2, Figure 2, represents a number of main dials which register the total of the numbers which are added together. These dials consist preferably of cup-shaped wheels which are numbered on their periphery and are mounted in their proper order on a transverse dial shaft 3, which is journaled in bearings on 4 the main frame, the dials being so arranged that the dial representing the lowest number is arranged on the right hand end of the series and the dials representing the successively higher numbers being arranged successively in their order toward the left from the dial representing the lowest number. The lowest or right hand dial is preferably divided on its periphery into eighths so as to indicate fractions of a cent in eighths, and the remain ing dials are graduated on their periphery according to the decimal system into tenths. As shown in the drawings, ten total dials are shown and extend from fractions of a cent to tens of millions, but if desired, additional dials may be added to the right and to the left of the series. if it is desired to register smaller divisions of a cent or more than tens of millions. Each of the main total dials 2 is pro- I vided on its left hand side with a gear pinion 4, which is rigidly connected therewith, as shown in Figure 2. The pinion of the fraction wheel has eight teeth while the pinions of the remaining dials are each provided with ten teeth. 5 represents the main registering gear segments, one of which is provided for each of the dials 2 and is adapted to engage with the pinion thereof. for operating the respective dial. Each of these gear segments is arranged in rear of its companion gear pinion and is provided at its lower end with a rearwardly projecting arm 6 which is pivoted loosely on a transverse supporting rod 7. This rod is mounted with its ends on the upper ends of two rock arms 8 which turn loose ly with their lower ends on a transverse. rockshaft 9. The rock-arms 8 are connected by a transverse bar 10 which compels the two arms to move back and forth together. In the nor .mal position of the gear segments when the machine is at rest these segments are retracted rearwardly out of engagement with the dial pinlons of the dials and the segments are elevated so that their lowermost teeth are opposite the space between the adjacent teeth of the dial with the pivots of the segments.

The gear segments are yieldingly held backwarclly out of engagement with the dial pinions by means of springs 11 connecting the rock-arms 8 with a stationary part of the frame. Figure 9 shows one of the springs 11 connecting one of the rock-arms 8 with a transverse stationary bar 12 in the rear part of the machine. moved forwardly so that 'their teeth engage with the dial pinions 4 by means of a shifting rock-arm 13, which .is preferably secured to the right hand rock-arm 8 and projects rearwardly. Upon raising the shifting rock-arm 13, the rock-arms 8 are swung forwardly and the gear segments 5 are enaged with the dial pinions. While upon swinging the shifting rock-arms downwardly, the rock arms 8 are swung rearwardly and the gear segments are disengagedfrom the dial pinions. v

1 1 represents a cam whereby the gear'seg ments are engaged with the dial pinions.

p1n1ons and the gear The gear segments are This cam is mounted on the upper portion of a vertically swinging rocking frame 15 which is arranged on the right hand side of the machine. This cam is provided at its front end with an incline or cam face 16 and at its rear end with a concentric, face 17 When the cam is in its rearmost or retracted position, its incline stands in rear of a roller or projection 18 on the rear end of the shifting arm 13 as shown in Figures 2 and 10. Upon swinging the rocking frame 15, so that the cam 14 moves forwardly, the incline of the latter engages underneath the roller 18 and raises the arm 13, thereby moving the arms 8 forwardly. The throw of the incline 16 is just suflicient to engage the teeth of the gear segments with the dial pinions. When the roller 18 has been raised to the top of the incline, the concentric portion of the cam enaffect the arm 13 and the parts connected therewith, but is affected by said arm at the last portion of the backward movement of Y the cam, at which time the back or lower side of incline 16 engages with the roller 18 which lifts said incline and at the end of the backward movement of the cam, the latter clears said roller and drops behind the same, as shown in Figure 2, preparatory to again ra1sing the roller 18 and connecting parts during the next forward movement of the cam 14.

For the purpose of permitting the front end of the cam to rise so as to clear the roller 18, this cam is pivoted at its rear end to the rear portion of the rocking frame 15, The upward and downward movement of the front end of the cam is limited b means of a lug projecting from the side of t e camand engaging with a slot in the adjacent part of whereby said shaft is rocked and the parts connected therewith are operated.

The gear segments 5 are raised to their highest position by means of a return or lifting bar 22 which extends transversely underneath all of the arms 6 of the gear segments and which is connected loosel at its rear ends with the transverse rod 7 by ifting plates 23. 24: represents two shifting arms which are ment with the transverse bar 25.

' forwardly during permitted to move downwardly with the bar until the segments are arrested.

Each of thegear segments is yiel-dingly held in contact with the lifting bar 22 by a spring 27 which connects the arm of the seg- If the downward movement of the gear segment is arrested while the shifting arms 24 continue to move downwardly, the lifting bar 22 is moved away from the underside of the arm of the gear segment and the spring 27 is strained. The transverse bar 25 is arranged at one end in a segmental notch 28 formed in the front part of the rocking frame 15, shown in Figures 2 and 10, and its opposite end is arranged in asimilar segmental notch 28, formed in a rocking frame29 (Fig. 10) which is secured to the operating shaft 20 on' the left hand side of the machine. The rocking frames 15 and 29 together with the operating shaft 20 constitute the main or universal operating frame of the machine.

When the machine is at rest, as shown in Figure 2, the transverse bar 25 engages with the front side of the notches 28 in the rocking frames 15 and 29. Upon turning the rocking shaft 20 forwardly, by means of its handle 21, in the direction of the 'arrow, Figure 2, the roc (ing frames are moved the first part of the movement independently of the transverse bar 25. The latter remains at restuntil the inclined front end 16 of the cam 14 has raised the arm 13 and moved the gear segments into engagement with the dial pinions, during which movement the rocking frames move idly the extent of their notches 28 along the ends of the bar 25 without disturbing the latter. After the gear segments have been engaged with the dial pinions, the. continued forward movement of the rocking frames causes the rear ends of their notches 28 to engage with the bar 25 and depress the same, thereby causing the lifting bar 22 to be moved downwardly and strain the springs 27. This causes all of the gear segments which are free, to be moved downwardly and to continue their downward movement until they are arrested. During the downward movement of the gear segments, while they, are in engagement with the dial pinions, the latter and the dials connected therewith are. turned until the downward movement of the segments is arrested. The extent which each dial is turned depends upon the position in which the downward movement of its operating segment is arrested. After the segments have been arrested in their downward movement, they remain in this position while the rocking frames complete their forward movement. At the end of the forward movement of the rocking frames, the roller 18 of the rock arm 13 drops off from the rear end of the concentric part of the cam 14, thereby allowing the springs 11 to pull the gear segments rearwardly out of engagement from the dial pinions. v

Upon now turning the rock-shaft 20 backwardly by means of the hand crank, Figure 10, the rocking frames are moved backwardly until the front ends of the notches engage with bar 25. \Vhen the latter is so engaged it is moved backwardly with the rocking frames to the end of their rearward movement which causes the transverse bar 25 to lift the lifting bar 22 and the" gear segments which have been depressed into their highest or normal position. During this upward movement of the depressed gear segments they are out of'engagement with the dial pinions, so that the dials are not turned backwardly with the segments, but remain in their shifted position. 30 represents a number of elbow-shaped controlling arms, which form part of the devices whereby the downward movement of the registering gear segments is controlled. One of these arms is'arranged along the left hand side of each gear segment and consists of an upright front part and a horizontal lower part which extends rearwardly from the lower end of the upright part, thereby leaving a clear space in rear of the upright part of the controlling lever, as represented in Figures land 2. The rear end of the lower part of each controlling arm is mounted loosely on .a transverse supporting bar 81, while the upper end of its front or upright part is loosely connected with the upper portion of its companion gear segment. This loose connection permits the controlling arm and the gear segment to swing freely about their individual axes, which are arranged parallel but out of line, and also permits the gear segment to move forward and backward into and out of en-, gagement with its companion dial pinion. The transverse stop bar 32, (Fig. 2) definitely limits the upward movement of the controlling arms. Each controlling arm is'provided on the rear part of its upper end with a locking lug 33, and on the front part of its upper end witha stop lug 3 1, both of which lugs project toward the left and are preferably stamped out in one piece with the controlling arm.

The operation of the registering device is controlled by a number of elbow-shaped key levers which are arranged side by side and pivoted to a transverse supporting rod 35.

All.

Each key lever is provided with a lower actuating arm 36, which projects forwardly, and an upper stop arm 37 which projects upwardly along the left hand side of one of the controlling arms and gear segments as represented in Figure 2. Each of these key levers is provided onthe rear side of its stop arm with a locking shoulder 38 which is adapted to engage with the locking lug 33 of the controlling arm when the latter is elevated into its highest position and the keylever is in its fully retracted position, as shown in Figure 2. When the parts are in this position, the key lever holds the controlling arm against downward movement and the latter holds the gear segment against downward movement. If the gear segment while so held against downward movement is moved forward into engagement with the adjacent dial pinion, and the rocking frames are turned forwardly for depressing the gear segment, the spring 27 ofthis segment will be strained without however, shifting the wardly thereon,

segment. At the end ofthis forward movement of the rocking segments the roller 18 of the rock-arm 13 drops off from the rear end of the cam 14, the gear segment is moved rearwardly out of engagement from the dial pinion and then the rocking frames move ackwardly without having shifted the dial. s The upper arm of each key lever is provided on its front side with a verticalfseries of differential stop shoulders 39, which arearranged step fashion and extend from the upper end of this arm downwardly and foror in other words the stop shoulders 39 are arranged radially out-of line with one another and different distances from the pivot of the key lever, These stop shoulders of the key lever are adapted to be moved forwardly into the path of the stop lug 34 of the controlling arm. The stop shoulders are arranged different distances from the stop lug 34 of the controlling arm, so that by moving different stop shoulders of the key lever into the path of the stop lug of the controlling arm, the latter and the gear segment connected therewith may be arrested at different points in their downward movement. The uppermost stop shoulder of the key lever is most remote from the. stop lug of the controlling arm, and therefore requires the greatest forward movement of the key lever, in order to bring this stop shoulder into the path of this stop lug. The stop shoulders of the key lever are so arranged that the distance from the stop shoulders to the path of the stop lug gradually grows less from the uppermost stop shoulder to the lowermost stop shoulder. The relative position of the different stop shoulders of the key lever is such that when its locking shoulder 38 remains in engagement with the locking lug 33 and the gear segment is simply moved into and out of engagement with its dial pinion, the latter remains at zero, if the same has not been previously moved. But when the key lever has been moved forwardly, so as to disengage its locking shoulder from the locking lug and moves one of its stop shoulders into the path of the stop lug of the controlling arm, the latter arm and gear segment connected therewith will be moved downwardly upon moving therocking frames forwardly, until the stop lug of the controlling arm strikes the respective stop shoulder of the key lever which stands in its path, whereby the gear segment while turning in engagement with the adjacent dial gear pinion turns the same forward. By turning the key lever forward more or less and moving one of the other of its stop shoulders into the path of its stop lug 34 of the controlling arm, the distance which this arm descends can be varied, thereby varying the number of spaces which its gear segment turns the adj acent' dial.

Main number key mechanism 40 represents the main keys whereby the key levers of the main registering and recording mechanism are operated, and WlllCh are guided with their depending stems in the top 41 and the bottom 42 of the keyboard. As shown in the drawings, nine longitudinal columns of these keys are arranged transversely side by side. The first column on the right-hand side of the machine contains seven keys and represents fractions of one-eighth of a cent, the next column toward the left contains nine keys and represents cents and the remaining columns of keys toward the left each contains nine keys and represent progressively-higher orders of numbers according-to the decimal system, so that the registering keys in the last or left hand column represent hundreds of thousands of dollars. V

The lowest 'numbers of the several columns of keys are arranged transversely in a row on the rear part of the keyboard and the corresponding higher numbers of the several columns are arranged likewise in transverse rows and progressively in their order towar the front end of the keyboard.

Each of the registering keys is yieldmgly held in an elevated position by a spring 43 surrounding the stem of the key and connected at its upper end to the key and hearing with its lower end against the bottom of the keyboard. The upward -movement of each key is limited by a shoulder 44 formed on the upper part of its stem and engaging with the underside of the top of the keyboard. The downward movement of all of the keys is substantially the same, but the arrangement of each column of keys lengthwise of the lower actuating armof each key lever causes the keys to bear against their lever at different distances from its pivot, so that by depressing most stop shoulders are shifted into the path of the stop lug 34 of the respective controlling arms. The throw of each key lever upon depressing any one of its keys is so adjusted, that the proper stop shoulder on its upper arm is'inoved into the path of the stop lug 34 of the controlling arm, and the downward movement of the respective gear segment is arrested after having turned the adjacent dial gear pinion a number of spaces corresponcL ing to the number of the key which is depressed.

Loose connection for segments The loose connection between each controlling arm and its gear segment, heretofore referred to, is shown in its simplest form in the connection between the controlling arm and the gear segment, which are controlled by the initial or lowest columh of registering keys. As shown in Figures 1 and 12 the loose connection between the controlling arm and the gear segment of the lowest registering ,device consists of upper and lower guide lugs 45 and 46 arranged on the upper end of the seg ment and bearing against the upper and lower guide faces 47 and 48, which are formed on the upper end of its companion controlling arm. As the controlling arm and segment rise and fall, the guide lugs of the segment slide back and forth on the guide faces of the arm. The guide faces are so constructed that the back and forth movement of the seg ment on the arm is radial with reference to the dial pinion in all positions of the segment. By so forming the. guide faces of the arm, the gear segment can be engaged with and disengaged from the dial pinion in all positions of the segment without disturbing the position of the dial pinion. 4 The construction of the loose connections between the controlling arms and gear segments of all of the higher registering devices above the fractional reg1stering device is combined with carrying devices, whereby each registering dial, upon making one complete turn, causes the next higher dial to be turned forward one space,

thereby carrying up a. number from one order to the next higher order. The loose connections between the controlling arms and the'segments-and the carrying mechanism of the higher registering devices are constructed as follows 7 As shown in Figures 1, 2 and 11, each controlling arm is provided at its upper end.with

upper and lower guide faces 47 and 48 and its lower guide face is engaged by a lower he same as in coupling between the controlling arm and segment of the initial registering device. The gear segments of the higher registering devices are each provided with an upper guide lug 49 which is adapted at times to bear against theupper guide face 47 of the companion controlling arm in substantially the same manner in which the up per guide lug 45 of the fractional gear segment bears against its companion arm, the only difference being that the upper guide lugs 49 of the higher gear segments are held out of engagement and separated by a space from the upper guide face of the companion arm whenno number is carried from a lower to a higher registering device. The upper guide lug 49 is held in this elevated position above the adjacent guide face bya rocking latch 50 which is arranged in a notch in the rear side of the gear segment and which normally projects toward the left and engages with the upper guide face 47 of the adjacent controlling arm, as shown in Figures 2 and 11.

During the ordinary up and down movement of each highercontrolling arm and gear segment, the latter is guided by its lower guide lug 46 and the locking latch 50 engaging with the lower and upper faces of the adjacent' arm, this movement being the same as the movement of the controlling arm and gear segment of the fractional registering device. Normally the downward movement v of the controlling arm is determined by the position of its companion key lever and this armin turn controls the extent of the downward movement of the gear segment. When, however, the locking latch 50 is withdrawn out of engagement from the upper guide face 47 of the arm, the companion gear segment is capable of moving downward independently of the arm until the upper guide lug 49 engages with the upper guide face of the arm. The extent of this independent movement of the gear segment with reference to its companion arm is equal to one tooth or space of the segment, so thatby this means the gear segment is enabled to turn the dial ,plnio'n one space more than the position of the key lever permits the same to move. I The withdrawal of the locking latch of each higher registering device is controlled by the next lower registering device and the withdrawal of each latch is effected when the next lower registering device has made one complete turn and arrived at zero. Each of the locking latches is pivoted on the right hand side of its adjacent gear segment, so

as to turn transversely with reference to the latter. The latch is turned toward the left into its operative position by a spring 51, the movement in this direction being limited by a shoulder 52 arranged on the latch and I bearing against the right hand side of the guide lug 46 on the adjacent gear segment,

gear segment. 53 tFig. 11) is an upright each latch and arranged normally at right angles or nearly so to the adjacent gear segment, when the latch is in its operating position. 54 (Fig. 4) represents a number of upright trip arms, each of which is controlled by a lower registering device and which turns the locking latch of the next higher registers its lowermost point near the axis thereof and then extend outwardly in a spiral line terminating with its highest point in line with its lowermost point with which its connects radially and abruptly. The trip cam of the fractional registering device has its face divided into eight parts, each part of which except the first is arranged one-eighth of a space further from the center of the cam than the preceding part, while the trip cams of the higher registering devices each has its face divided into ten parts, each part except the first being arranged one-tenth of a space farther from the axis of the cam than the preceding part. Each of the trip arms 54 extends upwardly along the right-hand side of the trip camw of a lower registering device, and its shoulder 56 engages with the face of this cam, while the hook 55 at its upper endextends toward the left and is adapted to engage with the trip plate 53 of the next higher registering mechanism. ltn the initial position of each trip arm, its shoulder 56 engages with the lowest part of its trip cam, as

represented in Figure 2. As thetrip cam is turned in the direction of the arrow, Figure 2, at the same time that its dial and gear pinions are moved forwardly by the adjacent gear segment during the adding operation, the trip arm is moved backwardly by the gradually rising face of the trip cam. During this backward movement of the trip arm, its book engages with the trip plate 53 of the next higher registering device and is deflected toward the right thereby, the hook being sufficiently elastic for this purpose. After the hook has passed in rear of said trip plate, the hook owing to its resilience springs back to its normal position, so as to stand behind said trip plate. When the shoulder of the trip arm reaches the highest part of the face on the trip cam the trip arm has been shifted to its rearmost position. Upon now turning this cam forwardly another space together with its companion dial and pinion, the highest part of the cam is carried from underneath the shoulder of the trip arm and the latter is moved forwardly over the abrupt face of the cam until its shoulder 56 again engages with the lowest part of-the cam face. During this movement of the trip arm, its hook strikes the rear side of the trip plate 53 of the next higher registering mechanism and turns the same forwardly, thereby disengaging the locking latch from the adjacent controlling arm and permitting the gear segment carrying the trip plate to move forward one space. The forward movement of the trip arm is effected when the dial with which its trip cam is connected has made one complete rotation and again stands at zero, whereby the addition represented by this complete rotation is carried to the next higher registering device. The forward movement of the trip arm is effected quickly by a spring 58, which connects with a stationary cross bar 59 arranged in front of the trip arms. The trip plate 53 of each registering device is so arranged and is of such length that the hook of the next lower trip arm cam engage with the rear side of the plate, for disengaging its latch in any position of the gear segment carrying the plate, and in order to accomplish this engagement itis obvious that cams 57 should be constructed so as to give arms 56 the propor throw. If a gear segment is locked in its highest osition by reason of none of its companion eys having been depressed, the withdrawal of its latch from the controlling arm simply permits the gear segment to drop one'space and turn its companion dial pinlon forward one space, while in engagement therewith, the movement of this dial representing one number carried up from the next lower dial. If any one of the keys of the key levers has been depressed, so as to release the gear segment and permit the same to move downwardly for effecting an addition, and if during this time the next lower registering device has made a complete turn, so as to require the carrying up of a number from the next lower registering mechanism, the latch of the higher registering device will be withdrawn while the same is effecting its addition, thereby causing the segment todescend and turn its'dial one space in addition to the space corresponding to the depression of its respective key.

When the locking latch has been withdrawn so as to permit a gear segment to move downwardly one space farther than its controlling arm, the latch remains in this position during the subsequent upward movement of the arm and the segment, until the upward movement of the arm is arrested by striking the stop bar 32, and the gear segment continues its upward movement independently of the arm the extent of one space. The gear segment has now reached its highest position and its latch is again swung automatically by its spring over the controlling arm. The controlling arm and gear segment now remain in this relative position until another number is to be carried up from the next lower registering device.

When the controlling arm has been retracted to its highest position, the adjacent key lever is moved into its normal retracted position, so that its locking shoulder 38 engages with the locking lug 33 of the controlling arm and locks the latter against downward movement. The return movement of each key leveris preferably effected by a spring 60 which connects the upper arm of the key lever with the transverse shaft 9, as shown in Figure 2, or with some other convenient part of-the machine. The lower cents.

guide lug of the gear segment is not absolutely necessary because the weight of the parts connected with the controlling arm and arranged in rear of its pivot is sufficient to raise the arm, but it is preferable to employ this lower guide lug 46 on the gear segment because it compels the arm to rise with the gear segment and avoids displacement of these parts with reference to each other, and also serves as a stop to limit the upward movement of-the gear segment.

The gear pinion and the co-operating gear segment of the fractional registering device are so constructed that the fractional dial makes one rotation whenever it is moved forward eight spaces. .After the fractional dial has made one rotation the whole number represented by this rotation is transferred by the first carrying device from the. registering mechanism of the fractional dial to the next higher registering device which represents he complete turns of each of the following registering devices are in like manner carried or transferred to the next higher dial by the respective carrying device. The dial which records the highest number, in this instance the millions of dollars is preferably operated only by the adjacent car-rying device of the next lower dial and is incapable of being operated directlv from the keyboard because'it,is not provided with a. key operating mechanism.

The mechanism whereby the dials are all turned back to zero or the place of beginning after the addition of numbers has been completed is constituted as follows:

61 (Fig. 2) represents a series of feeling rock levers which are adapted to shift the key levers, so as to permit the gear segments Loosely on the supporting bar 35 adjacent to" the left hand side of each of the key levers and is provided on its upper arm with a forwardly projecting feeling finger 62 and with a shifting finger 63 which extends laterally behind the upper arm of the adjacent key lever. The feeling levers have their fingers arranged in rear of the total cams 57, and

each of these levers is turned so that its uprepresents a transverse pull bar arranged in rear of the lower arms of the feeling levers and connected with each of .the latter by a pull spring 65, as represented in Figures 2 and 10. "lhis pull bar is connected at its ends to the lower ends of two depending pull or rock arms 66, which are secured at their upper ends to the rock shaft 9 as shown in Figure 10. Upon turning this rock-shaft, so as to swing its depending pull arms backwardly the feeling levers are turned by means of the springs 65 so as to move the upper arms of these levers forwardly. This movement of the rock-shaft 9 is effected by a cam (V (Fig. 9), which is mounted on the lefthand side of the rocking frame 29 and which is constructed substantially the same as the cam 14 which is mounted on the rockingframe 15. As shown in Figures 9 and 10, this cam is pivoted near its rear end by a transverse pin to the rear portion of the rocking frame 29 and is provided at its front end with an incline or cam face 68, and in rear of the incline with a concentric face 69. The cam 67 is pivotally supported on the rocking frame 29 in the same manner in which the like cam 14 is pivoted on its corresponding rocking frame 15. The cam 67 can be raised and lowered with its front end into an inoperative or operative position, this movement being limited by means of a lug 7 0 arranged on the cam as shown in Figure 10, and projecting into a slot 71 in the adjacent rocking frame in the same manner in which the movement of cam 14 is limited.

72, Figures 9 and 10, represents a rearwardly projecting rock-arm secured to the rock-shaft 9 and provided at its rear end with a roller or projection 7 3 which is adapted to be engaged by the cam 67 for turning the rock shaft 9. When numbers are being added with the machine, the cam l l is depressed, as shown in full lines, Figure 2, so as tobe in a position when moved forwardly by the rocking frame 15 to engage the roller on the arm 13, for moving thegear segments into engagement with the dial pinions, and during this time the cam 67 is lifted into the position shown in full lines, Figure 9, so that when the rocking frame 29 is moved forwardly, the cam 67 will clear the roller 73 of the rock arm 7 2 and not disturb the rock shaft 9 and the parts connected therewith.

If it is desired to restore all of the total dials 2 to zero, the cam 14 is raised into its inoperative position, shown by dotted lines in Figure 2, and the cam 67 is lowered into its operative position, as shown by dotted lines 67 in Figure 9. Upon now turning the rock shaft 20 by hand so as to move both rocking frames 15 and 29 forwardly, the cam 14 passes over the roller 18 of the arm 13 without disturbing the same, but the inclined front of the cam 67 engages with the roller 7 3 on the rear end of the rock-arm 72 and raises the same until this roller engages with the concentric part 69 of this cam. By this movement of the arm 72, the rock shaft 9 is turned in the direction for moving its depending arms 66 rearwardly and pulling the springs rearwardly. This pull on the springs 65 causes the feeling levers to be turned until the feeling fingers of their upper arms engage with the spiral surfaces of the trip cams. After the feeling fingers bear against these cams, their movement is arrested and the continued backward movement of the pull bar 64 simply stretches the springs 65 until the bar reachesthe end ofits backward movement. The feeling finger of each feeling lever engages with that part of the surface of the adjacent trip cam which is directly opposite the feeling finger, and as these trip cams are turned with the-adjacent dials they present difi'erent parts of their spiral surfaces to the opposing feeling fingers, which causes the forward movement of the upper arms of the feeling levers to be arrested in different positions when swung forwardly. During the forward movement of the upper arm of each feeling lever, its shifting finger 63 engages with the rear side of the upwardly projecting arm of the adjacent key lever and moves this arm forwardly. The construction of the parts is such that the spiral surfaces of the trip cams bear a definite relation to the step-shaped series of stop shoul ders on the upper arm of the key lever. When the feeling finger of. the feeling lever, upon being moved forwardly, bears against the lowest key-lever-stop-controlling part of the adjacent trip cam, the adjacent key lever is carried simultaneously forward with the feel ing lever the greatest distance audits uppermost stop shoulder is carried into the path of the stop lug of the controlling arm. The succeeding parts of the spiral surface of the trip cam are so constructed that they rise progressively higher and arrest the forward movement of the feeling lever when the same has carried the ad acent key .lever with its corresponding stop shoulder into the path of the stop lug of the controlling arm. This forward movement of the feeling lever and that of the upper arm of the key lever is gradually reduced as the progressively higher parts of the trip camvare presented to the feeling finger, and when the highest part of the trip' cam is presented to the feeling finger, the feeling fever is prevented from moving forward at all and the upper arm of the key lever is not moved with its locking shoulder out of engagement with the locking stop of the controlling arm and consequent- ,ly the companion gear segment connected therewith is held against downward movement. After the rocking frames 15 and 29 have been turned forwardly sufliciently to engage the several feeling fingers of the feeling levers with their respective trip cams, the rear ends of the segmental notches 28 in the rocking frames engage with the cross bar 25 and depress the same, thereby moving the lifting bar 22 downwardly and at the same time pulling down the springs 27. This downward pull on these springs causes each spring to pull its respective gear segment down as far as possible, and after the downward movement of the segment has been arrested the continued downward movement of the cross bar 22 together with the rocking frames simply stretches these springs until this bar reaches the end of its downward movement. If a gear segment is locked in its uppermost or zero position its spring 27 will be stretched its fullest extent. whereas, if a gear segment moves downwardly more or less before it is arrested by its shifting key lever, its spring 27 will be'stretched less in proportion. This downward movement of the gear segments which are free to move in this direction takes place While the gear segments are in their retracted position and out of engagement-from the dial pinions, so that the dials are not affected by this movement of the segments.

After the rocking frames have the end of their forward movement and the roller 73 has dropped off from the rear end of the concentric portion 69 of the cam 67, the gear segments are moved forwardly by hand operated mechanism into engagement with their respective dial pinions and are held in this position during the entire subsequent backward movement of the rocking frames, which is effected by hand operated mechanism. During the backward move- .ment of the rocking frames, the gear segvments are raised to their highest positions,

while in engagement with the dial pinions by the rod 22 and connecting parts and turn the dials backwardly. At the end of the upward movement of the gear segments the.

latter are released, so as to permit them to move into their retracted position, out of engagement from the dial pinions.

During this operation those'gear segments which are held or locked in their highest positions, by reason of their dials being at zero, are simply moved forward at the end of the forward movement of the rocking frames, so as to engage with their respective dial pinions and are again rnoved backwardly out of engagement therefrom'at the end of the forward movement of the rocking frames, without disturbing their respective dials. Each of the unlocked gear segments is moved downwardly a number of spaces corresponding to the number which is regreached sition,

the gear'segments forwardl in their variously depressed positions and t en raising them to their highest po-,

each depressed gear segment will turn its dial backward the same number of spaces that the gear segment was depressed. Inasmuch as each gear segment was permitted to descend by its trip cam, feelin lever and key lever the same number 0 spaces vas the number indicated on its dial, the gear-segment subsequently moves upwardly the same number of spaces before reaching its highest position, thereby turning its dial backwardly the same num- "ber of spaces and restoring the same to zero.

The mechanism whereby the positions of the cams 14 and 67 are reversed preparatory to restoring the dials to zero is constructed as follows:

" The earns 14 and 67 drop into their op- .erative position by gravity. Each of these oams'is provided in rear of its pivot with a tail 75 which is depressed when it is desired to lift the respective cam into its inoperative position.- I

76 is a shifting lever which is pivoted at its lower end and is normally turned so that its upper end is disengaged from the rear 'side of the tail on the cam 14 by a spring 77,

' jects in rear of the mainframe so as shown in'Figure 2. The member 76 proas to be 78 (Fig.

accessible for manual operation.

7 9) is a shifting lever which is pivoted be- I pivoted tween its upper and lower arms and arranged with its upper arm in rear ofthe tail of the cam 67'and normally held in engagement therewith by a spring 7 9, as shown in Figure 9.- 80 represents an elbow lever below the bottom of the keyboard, as represented in that figure, 81 represents a main line-or cord which is connected with the lower arm of the elbow lever 80 and whichis provided at its rear end withtwo branches 82 and 83. The branch 82 connects with the shifting lever 76 above its pivot, and shifting lever 78 below its pivot. 84 represents a total or shifting key having a de pending stem which is guided in top and bottom plates of the keyboard and which bears with its lower end against the upper armof the, elbow lever 80. Upon depressing the key 84, the elbow lever 80 is turned, .soas to .draw the cords or lines 81, 82 and 83 forwardly thereby moving the upper end of the shifting lever 7 6 into engagement wlth the tail of the'cam 14 and lifting the same the branch 83 connects with the into an inoperative position, while the shifting lever 78 is moved rearwardly with its upper arm from the tail of the cam 67, thereby allowing the latter to drop into its operative position. Upon depressing thegear segments while the parts are in this shifted position, the segments move downwardly out of engagement with the dial pinions. After the gear segments have been depressed the are moved forwardly into engagement wit their respective dial pinions by an elbow lever 85 which 'is connected with its lower arm by a line or cord 86 to the rod or bar 7, as shown in Figure 9, or to one of the rock arms 8. I

The elbow lever is turned in the proper direction for this purpose by a shifting key 87 having a depending stem which is guided in the top and bottom of the key-board and which bears against the upper arm of the elbow lever 85 After the gear segments have been moved forwardly into engagement with .the dial pinions, while in the depressed position, the gear segments are retained in forward position, and at the same' time raised until they reach their uppermost position, whereby the dials are turned to zero. The shifting key 87 is now released Which permits the spring 11 to move the gear segments rearwardly out of engagement with the dial pinions. The key 84 is also released, thereby permitting the shifting levers 76 and 78 to resume the positions shown in Figures 2 and 9, leaving the-machine .in position to resume adding.

Each of the dials is held against turning while out of engagement with its companion gear segment, by means ofa detent awl 103 which engages with the front side 0 its companion gear pinion, .as shown in Figure 2. The pawls 103 of the several gear pinions are mounted on a transverse pawl bar 104, which is supported at its ends by means of two pawl arms 105, which turn loosely upon the suptent pawls are swung forwardly out of engagement with the dial pinions by means of two shifting rods 107 which are connected at their rear ends to opposite ends of the transverse rod 7 or some part moving therewith and each of which is provided at its front end with a fork or bifurcation 108, which engages with a pin or shoulder 109 on the pawl arm arranged on the adjacent side of the machine. As the gear segments move forward into engagement with the gear pinions, the shifting rods 107 move the detentpawls 103 out of enill gagement with the dial pinions and when the gear segments move backwardly the detent pawls are again engaged with the dial pinions by the springs 106.

Recording mechanism For the purpose of recording the numbers which are added together'by the above described mechanism a recording mechanism is provided which is constructed as follows:

140 (Figs. 1, 2, 3, 9 and 10) rep-resents a printing roller or platen which is arranged transversely in the upper, rear part of the machine and under the lower side of which the sheet or other article is placed which receives the record. 141 represents a number of type segments which are arranged transversely side by side below the platen and which are pivoted at their front ends to the supporting bar 31 upon which the rear ends of the controlling arms are pivoted. Each of these type segments is provided at its rear" end with a segmental row of type carriers 142,. which are capable of moving radially back and forth on the typesegment.

Each of the type carriers is provided at its rear end with a type and is guided upon the type segment by means of screws or rivets 143 (Fig. 5) secured to the type carrier and arranged in radial slots 144 formed in the type segment, as shown in Figures 2 and 5. Each of the type carriers is held in its inward or platen.

retracted position by means of an S-shaped spring 145, which is arranged between the.

carrier and the type segment and is secured with one end to the carrier and with its other end to the type segment. Upon raising or lowering the type segment any one of its type can be brought to the printing point or line, and upon striking the back or inner end of the type carrier, when the same is in line. with the printing point the-type carrier will be driven outwardly and its type will produce an impression on the sheet supported by the After the carrier has received the blow for driving the same against the platen, the carrier is again quickly retracted to its innermost position by means of its spring. Each of the type segments is connected with one of the controlling arms, so that upon depressing a controlling arm and the registering gear,segment connected therewith the companion type segmentwill be raised and present one of its type to the printing point. For convenience in operating the machine, the keys are separated a considerable distance on thekey-board and in order to produce a compact record, theprinting segments are arranged closer together than the keys and the registering mechanism. In order to permit of this arrangement, each type segment and its corresponding controlling arm are connected by a connecting arm 146, as represented in Figures 1, 2, and 11. The connecting arms of the central controlling arms rmaeae and type segments are comparatively straight but the connecting arms of the outer type segments and controlling arms are arranged obliquely, the degree of this obliquity gradu ally increasing from "the central type segments and controlling arms in opposite directions toward the outer type segments and controlling arms, as represented in Figure 1.. The connecting arms 146 of the outer controlling arms are arranged in the spaces behind the upright parts and above the horizontal parts of the controlling arms, thereby permitting the inner controlling arms to move up and down without interfering with the connecting arms, 146 of the outer controlling arms.

The types on each type segment are arranged to correspond with the teeth and numbers of its companion gear segment and registering dial, the zero type being at the upper end of the series and the progressively higher digits arranged in their order downwardly from the zero typeVVhen the registering gear segment is in its highest postion it presents its zero tooth to the dial pinion, and the type segment which at this time is in its lowest position presents its zero type to the printing point. Upon depressing a gear segment so as to present one of its higher teeth to the dial pinion, its companion type segment is raised proportionally and presents a corresponding higher number type to the printing ioint.

1 147 represents a number of hammers whereby the type carriers are struck for driving the type against the platen. One of these hammers is arranged adjacent to each type segment and is provided with a head which is arranged in front of the series of tvpes and in line with the printing point of the platen. Upon shifting the type segment so as to bring one or another of its type carriers to the printing line and then operating the hammer, the latter delivers a blow against the inner end of the particular carrier which is at the printing point and produces an impression of its type on the platen. The several hammers are pivoted on the transverse rod 12, arranged in rear of the segment; and each of the hammers is yieldingly held in its forward position by a spring 148 connected at its lower end to a cross bar 149 and at its upper end to a depending arm 150 on the hammer.

151 represents a vertically movable trip bar or rod which is arranged transversely below the'hammers and whereby the latter are operated. This bar is supported at its ends upon the rear end of rock arms 152 which turn loosely with their front ends on the rod 31 supporting the type segments and controlling arms.

153 represents a number of hammer or trip pawls, whereby the hammers are retracted preparatory to delivering a blow against the type carriers which are at the printing point.

-One of these pawls is arranged adjacent to each hammer and pivoted loosely at its lower end to the trip bar 151 and its upper end is provided on its rear side with a downwardly facing hook orshoulder 154, and above said shoulder with a trip face 155, as shown in Figure 6. in front of its pivot adjacent to the upper end of the hammer pawl with a lower trip lug or shoulder 156 and an uppertrip lug or shoulder 157. When the parts are at rest, the hammer pawl 153 is raised into its high est osition and the hammer is in its normal pos1tion with its lower trip lug 156 below and in-rear of the hook of the hammer pawl and with its upper shoulder 157 in rear'of the trip face" of the hammer pawl, asrepresented in Figures 2, 5 and 6.

\ Upon shifting the hammer pawl rearward ly, while the parts are inthis position, so that its hook overhangs the lower shoulder 156 of the hammer, and then pulling the. hammer pawl downwardly, the hook of the hammer pawl engages with the lower shoulder .of the-hammer and turns the same so. that its head is retracted from the type carrier at the printing line. As the hammer moves downwardly with the hammer pawl, the upper shoulder of the hammer comes into engagement with the trip face of the hammer pawl and during the continued downward movement of the hammer and its pawl, this upper shoulder gradually crowds the hammer pawl forwardly with reference to the hammer,,by reason of the hammer and its pawl swinging on different centers. During thelast portion of thedownward movement,

of the trip bar 151 and the hammer pawl mounted thereon, the pawl is crowded forwardly by the upper shoulder 157 of the hammer'to such an extent that its hook is disengaged from the lower shoulder 156 of the hammer, thereby liberating the latter and permitting its spring 148 to throw the same quickly and deliver a blow against the type carrier at the printing line. The trip bar151 now'rises and carries the hammer pawl into its highest position, preparatory to again engaging thehammer for depressing the same.

158 (Figs. 5 and 6) represents a number of upright shifting arms whereby the hammer pawls are moved rearwardly, so that their hooks engage with the lower shoulders of the hammers. One of t'hese'arms is arranged adjacent toeach hammer pawl, and is pivoted at its lower end on the trip bar 151, and its upper end is provided with a roller or projection 159 cam 160 on the lower part of the adjacent type segment as shown in Figures 5 and 11. This hammer cam is provided at. its upper end with a receding or lower portion, aninclined portion arranged below the low portion and a concentric or high portion .ar-

ranged below the inclined portion. Each Each of the hammers is provided which bears against a hammer 'with the adjacent hammer cam by a spring 161 connecting said arm with a cross bar 162 secured to the rock arms 152, as represented in Figure 3. The backward movement of each hammer pawl with reference to its companion shifting arm, is limited by means of a stop 163 secured to the upper portion of the hammer pawl and engaging with the front side of the shifting arm, as represented in Figures 5 and 6.

Each hammer pawl is yieldingly held in its rearmost position with reference to its shifting arm by means of a C-shaped spring 16 1 secured with its ends, respectively, to the hammer pawl and its shifting arm, as shown in Figures 2, 5 and 6. In the lowermost position of a type segment, the receding part of its cam is presented to the roller of the shifting arm 158, which permits the hammerpawl to be retracted into its foremost position, as represented in Figure 2. Upon depressing the trip'bar 151 when the parts are in this position, the roller 159 is not engaged soon enough by the incline of the cam 160 to engage the hook of the hammer pawl with the lower shoulder of the hammer, before the hook has passed below this shoulder, but

the particular type at the printing line isproduced. If the type segment is raised, so as to present one of its lower types to the printing point or line, the incline of its-cam during the first part of the upward movement of the segment moves the shifting arm 158 rearwardly together with the hammer pawl yieldingly connected therewith, so that the hook of the hammer pawl stands over the lower shoulder 156 of the hammer. Upon now depressing the pawl 153, the hammer will be retracted and released near the end of the downwardmovement of the pawl, and will be quickly swung up by the spring 148, thereby delivering a blow against'the type at the printing'point and producing an impression thereof.

The incline 160 of the type segment cam is so constructed that it throws the hammer pawl backwardlyinto an operative position when the segment is raised one digit space, and during the continued upward movement of the segment, the hammer pawl is held in this operative position by the high concentric part of the segment cam. By thus constructing the type segment cam its companion hammer pawl is not shifted when the segment is not raised and its zero type remains at the printing line, but the hammer pawl is shifted into an operative position for producing an impression, if the type segment is raised one or more digit spaces and presents any Automatic printing of zero 165 (Figs. 5 and 6) represents a number of transfer or coupling fingers which enable the ciphers in a number to be printed automatically. One of these transfer-fingers is secured to each of the shifting arms 158, as represented in Figures5 and 6, and extends laterally toward the right therefrom into engagement with the shifting arm of the next lower hammer pawl. If any one of the printing se ments remains in its lowest position, so that its cipher remains at the printing line and the next higher printing segment has been raised for printing a higher number or digit, the transfer finger of the higher hamme lr-shifting arm 158 while being moved rearwardly by the cam of its companion printing segment, is caused to engage with the shifting arm 158 of the next lower hammer pawl and shift the latter backwardly, so that its hook is carried backwardly over the lower shoulder of the companion hammer. Upon now depressing the trip bar 151, the higher hammer pawl 153 is coupled with its hammer and the next lower hammer pawl is also coupled with its hammer, whereby an impression of the cipher or zero type on the lower segment is produced on the platen at the same time that the next higher number is printed on'the platen. If two ciphers occur in succession in the body of a number, the shifting arm to the left of the highest order printing segment to be operated for printing a zero sets the hammer mechanism of said highest zero-printing segment by means of the transfer finger of said shifting arm, and the shifting arm of said highest zero-printing segment in turn by means of its transfer finger sets the hammer mechanism of the printing segment of next lower order, etc. This operation of producing an impression of the cipher type is effected automatically and renders it possible to print any number of ciphers in succession in the body of a number because the hammer operating mechanism of each segment which remains standing with its upper type at the printing line is controlled by the hammer operating mechanism of a higher type. segment and in turn controls the hammer operating mechanism of the next lower type segment if the next lower segment presents a cipher to the printing line. Only the ciphers below the highest digit in the number to be recorded are thus printed automatical- 1y because the printing of a digit depends upon the upward movement of a printing segment. thereby avoiding the printing of ciphers ahead of the high est digit in the number to be recorded. The han'imer-shifting device of the segment which prints the numbers representing units of cents 1s, preferably, not provided with a transfer finger to operate on more springs 166 (Fig. 3) which connect this bar with the transverse rod 12. and the upward movement of the bar 151 is arrested when the hammer operating pawls reach their highest position by a transverse bar 16? (Figs. 2. 3, and 9) which is engaged by the rear ends of the rock arms 152. 168 represents a coupling hook, whereby the hammer trip devices are depressed. This hook is pivoted with its upper end to the trip bar 151 and its lower engaging end is provided with a notch having upper and lower shoulders.

In the lowered position of this hook its notches engage with a cross bar 169 which is connected with the rock arms 24, as represented in Figure 2, so that the hook and the hammer operating devices connecting therewith a-re actuated from the rocking frames 15 and 29, through the medium of the rock arms 24. In the rearmost position of the .rocking frames, the front ends of their notches 28 bear against the front sideof the bar 25 to which the gear segments are yieldingly connected and the cross bar169 bears against the rear or upper shoulder of the notch of the hook 168, as represented in F igure 2. Upon swinging the rocking frames forwardly the incline of the cam 14 first raises the rock arm 13 and shifts the gear segments into engagement with the dial pinions, and after the segments have been so shifted, the rear shoulders of the notches 28 in the rocking frames, engage with the cross bar25, so that thereafter this bar is carried downwardly with the rocking frames and the gear segments are depressed. During this downward movement of the bar 25 with the rocking frames, the companion bar 169 moves downwardly in the notch of the hook 168 until this bar engages with the lower or front shoulder of this hook. After the cross bar 169 engages with the lower shoulder of the notch of the hook, the latter and the hammer operating devices connected therewith are moved downwardly with the rocking frames until these frames reach the end of their downward 'movement. During the last portion of the downward movement of the rocking frames the hammer pawls are disengaged as before described, from the retracted hammers, whereby the latter are released and strike the type carriers which are at the printing line. By this means the blow of the hammers is delivered after the registering of the numbers has been effected on the dials and the type segments have been shifted into their proper position for recording the respective number.

The hammers do not follow the type caroutwardly by the impact of the hammers and "are then returned by their springs so asto clear the printing surface.

shifting key N on? print me cham'sm Vhen it is desired to only add the numbers and not record the'same, the coupling hook 168 is raised with its notch out of engagement with the cross bar 169, which allows the rocking frames and connecting parts to move back and forth without affecting the hammerhpen' ating devices. The conpling hook is disengaged from the cross bar by means of an elbow lever 171 secured to a transverse rock shaft 17 2. The lower arm of the elbow lever is connected with the shaft 20 by a spring 173 whereby the lever and the shaft carrymg the same are turned inthe direction for disconnecting the upper arm ofthe lever 171 from the hook 168, thereby permitting the latter to engage the bar 169. 17 4 (Fig. 9) represents an elbow lever arranged below the bottom of the key-board and connected by a line or cord 175 with its lower arm to the upper arm of the elbow lever 171. 176 represents a having a depending stem which is guided in the top and bottom of the keyboard and which engages with its lower end against the upper arm of the elbow lever 174. Upon depressing this key the elbow lever 174 is turned in the direction formoving the rock arm 171 into engagement with the coupling hook 168 and disengaging the latter from the cross bar 169, thereby throwing the recording mechanism outof gear. .Upon releasing the key 176, the rock arm 171 1s permitted to swing backwardly and allow the couphng hook to engage with the cross bar 169, thereby throwing the recording mechanism into gear: 'When the gear segments and the print ing segments are thus operated relatively to c the keys which have been depressed, the numher represented by the depressed keys is registered and also recorded by the printing mechanism. The addition of further numbers proceeds in like manner, theseveral numbers being added successively by the registering mechanism but each number is printed individually by the recording mechanism.

When it is desired to print or record the total at the foot of the column of the numbers which have been printed, the operation is as follows :-The total key 84 is first depressed, thereby raising the cam 14 into an inoperative position and lowering the cam 67 into an operative position. Upon now moving the rocking frames 15 and 29 forwardly the feeling levers 61 are turned so as to 7 move their feeling fingers forwardly into enarms 150 engaging with a gagement with the respective cams 57, and at .the same time each feeling lever carries the adjacent key lever forwardly so that its particular stop shoulder 39 corresponding to the position of the trip cam 57 and its dial .is moved into the path of the stop lug 34 of the controlling arml After the key levers have been thus shifted forwardly into their respective positions corresponding with their dials, the continued forward movement of the rocking frames causes the gear segments while in a retracted position out of engagement with the dial pinions to be depressed until each segment is arrested by the engagement of the stop lug on its controlling arm with the respective stop shoulder of its key lever, whereby each printing segment is raised so as to present the type carrier to the printing point which carries the-type corresponding to the number registered on its companion dial. During the last part of the forward and downward rocking movement of the rocking frames the hammers are operated and the paron the platen. Upon now swinging the rockof engagement with their companion dial pinions, thereby permitting further' numbers to be added to the total already registered on the dials- If, however, it is desired to turn the dials back to zero, after the total of the added numbers has been printed or recorded, the gear segments, while in the retracted lower position which they occupy while printing the totals, are moved forwardly into engagement with their respective vdial pinions by the depression of the key 87. Upon now moving the rocking frames backwardly the gear segments are raised while in their forward position in engagement with their pinions, whereby each of the latter is turned backwardly and when the segments reach the end of their upward movement, the dials. have been turned backwardly a number of spaces corresponding to the number on the dial, thereby turning all of the dials to zero.

Word pfinting mecha m'sm y For the purpose of permitting words to be ing frames backward, the gear segments are raised whilestill in a retractedposition out printed in front of the numbers which are added together the following mechanism is provided:

1411 (Figs. 1 and 3) represents a word printing segment which is mounted loosely on the rod 31 next tothe highest number printing segment of the mam number recording mechanism. This segment is provided with a number of radially movable carriers 1420 (Fig. 3), which arerconstructed the same as the carriers of the number printing segments and each of which is provided on its face with a word-type. The words of these types are selected according to the "purpose or business for which the machtne is to'b'e used. ,For instance, if the machine is to be used in a bank, types representing the words Vouchers, Checks, Drafts, Bills, and similar words common to the banking business may be used. When the machine is designed for use in a restaurant the words Soup, Vegetables, Meats, Dessert, and other words peculiar to this business may be used.

The position of the word type segment is controlled by a key lever 3000, Figure 3, which turns on the bar '35, is similar to the number key levers and is provided on the front side of its upper arm 3700 with a vertical series of differential stops or shoulders 3900 which are adapted to be engaged by the stop lug 3-100 of a controlling arm 3000; and lever 3600 is also provided with a locking stop or shoulder which is adapted to be engaged by a locking lug 3300 on the controlling arm, as represented in Figure 3. The controlling arm 3000 is connected with the word printing segment by a connecting bar 1400. The stop shoulders on the upper arm of the word key lever are so arranged that upon swinging this lever so as to carry different shoulders into the path of the stop lug on the controlling arm, the latter will be arrested at different points in its downward or forward movement and the word printing segment connected therewith will be stopped at different points in its upward movement and present the particular word type in the printing point which corresponds with the shoulder or stop on the word key lever. The upward movement ofthe controlling arm 3000 is limited by its rear looking lug 3300 engaging with the stop bar 32 which arrests the upward movement of the cont-rolling arm 30 of the number registering and recording mechanism. The downward movement of the controlling arm 3000 and the simultaneous upward movement of theword printing segment are effected by a spring 215 which yieldingly connects this arm with the bar 25 to which the registering gear segments are connected.

216 represents a row of word keys having depending stems which are guided in the top and bottom of the key-board and which ongage against the upper side of the front arm 3000 of the word key lever at different distances from the fulcrum thereof. Upon depressing any of the word keys the word key lever will be turned the proper distance to bring its proper stop shoulder into the path of the stop lug of the companion controlling arm and arrest the word type segment during its upward movement, when the word typo corresponding with the word of the depressed key has reached the printing line. "When the respective word type is in this position the same is driven against the recording surface for producing an impression thereon, at the same time that the printing of the nun'ibcrs by the numbering printing segments is cffected. The word. types are driven against the platen by a hammer operating mechanism which is constructed the same as the hammer operating devices of the number printing mechanism and the same letters of reference are therefore used to denote the same. The word key lever is yieldingly held in its normal position by a spring 600.

00cm ting meal: an ism An auxiliary adding or counting mechanism is provided which permits of rcgister ing the number of adding and recording operations which have been made by the main adding mechanism. This mechanism is constructed as follows:

2000 Fig. 4) represents a number of auxiliary dials which are mounted on the left hand end of the dial shaft 3. 5000 (Figs. 1, 4C, and 7) represents a number of auxiliary gear segments which are mounted on the transverse rod 7 and are adapted to engage with gear pinions 100 on the auxiliary dials, as represented in Figure 4. Each gear segment 5000 is connected with a controlling arm 3001 arranged adjacent to the gear segment by a latch or coupling which at times permits the segment to move independently of the controlling arm. 3001-3701 (Fig. 1) represent auxiliary stop levers which in the original application are combined with auxiliary key mechanism, but for the purpose of the pres ent application these levers may be considered as merely for the purpose of maintaining the gear segments and controlling arms in normal position, and controlling the clearing operation.

Printing segments are shown in Figures 1 and 4 as connected with the tuxiliary controlling arms but these form no part of the present invention and might be replaced by any other suitable counter weight. The combinations in which the auxiliary key mechanism and the auxiliary printing segments form elements are claimed in the parent application 1,004 and in other divisions thereof, to which reference is hereby made.

Thedetail construction of the dials, gear segments and parts connected therewith is substantially the same as the construction of the same parts in the main registering and recording mechanism, except as hereinafter distinguished, and the same letters of reference are therefore employed to denote like parts in both of these sets of mechanisms.

In the drawings, suilipicnt registering mechanism is shown for counting to 000, but additional registering mechanism may be employed it it. is desired to increase the capacity of the machine.

In the counting mechanism, each of the higher gear segments 5000 is provided with a pivot latch 501 (Fig. 7) the same as in the main registering mechanism. The lowest or primary gear segment of the auxiliary registering mechanism is provided with a movable 1 panion guide arm,

on the segment adjacentto the latch bears se ment.

against the controlling arm. The extent of this drop of the primary segment independent of its controlling arm is equal to one space or-number' of the registering mechanismthe same as in the higher counting mechanisms.

In the counting mechanism, the gear segments are not provided with lower stops 46, which in the parent application and in certain other divisions thereof, permits the printing mechanism to work independently of the registering mechanism, but for the purpose of the present application, the stop 46 might be used if desired, the same as in.

the mam registering and recording mechanism. The upward movement of the auxiliary or counter gear segments is limited by stops 218 with which the upper ends of the gear segments engage. 219 represents a foot formed on the lower side of each controlling arm 3001 and adapted to engage with the lifting cross bar 22.. 220 represents springs whereby the controlling arms 3001 are connected with the cross bar 25.

222 (Fig. 7) represents a number of stops whereby the counting gear segments, when in their foremost position, are permitted to move downwardly only one space to count the number of additions which have been made by 'the main registering mechanism. One of these stops is arranged adjacent to the left hand side of each controllingarm 3001 and is provided on the upper side of its rear end with a curved guide face which corresponds to and is in line with the upper curved bearing face of the controlling arm when the latter is in its highest position, as represented in Figures 4 and 7. The several stops 222 are secured with their front ends to a member 223 which in the parent application and in some of the other divisions is movable, but for the purpose of the present application this member 223 may be considered as stationarily positioned with the stops 222 in the downward path of the stop lugs 490 and latches 501 and 502.

227 represents a trip finger secured with its front end to the member 223 and arranged with its rear end adjacent to the front side of the latch 502 of the units counter gear revious to beginning the consecutive counting of the separate additions of the main'registering mechanism, the dials are all the latch rearwardlyturned to zero, all of the upper key lever arms3701 are in their rearmost positions and have their locking shoulders 38 in engagement with the locking lug 33 of the controllingarms 3001, whereby the latter are held in their highest position. Upon moving the rocking segments 15 and 29 forwardly after depressing the proper keys of the numher to be added on the main registering mechanism, the gear segments are all moved forwardly into engagement with their re spective dial pinions and the springs 27 of the several gear segments are then pulled downward by the bar 25.

During the forward movement of the auxiliary tens and hundreds gear segments their latches 501 engage with their companion controlling arms which prevent these gear segments from being depressed by the pull of their springs 27, whereby the tens and hundreds dials are not turned. During the forward movement of the primary .or units gear segment its latch 502 engages with the trip finger 227 and is turned backwardly out of engagement with the top of its companion controlling arm, thereby releasing the units gear segment and permitting the same to be pulled downwardly by its spring 27, while in engagement with its gear pinion, whereby the units counting dial is turned. As the gear segments 5000 move forwardly into engagement with the dial pinions, their lugs 490 move over the stops 222, but in the foremost position ofthese gear segmentstheir stop lugs 490 are separated from the stops 222 a distance equal to one tooth of the segments or one space on the dials. The instant the latch 502 of the units gear segment is released from the units controlling arm, while the units gear segment is in its forward position the pull of thespring 27 depresses the units segment until its stop lug l90 engages with the units stop 222, this movement of the units gear segment causing the same to turn the units dial one space or number. During the subsequent backward movement of the rocking segments 15 and 29, the auxiliary gear segments are withdrawn rearwardly from the dial pinions. While in this rearwardly retracted position the units gear segment is raised by the bar 22 and when the same reaches the upper end of this movement the latch 502 is automatically turned engage the latch 501 of the tens gear segment from the tens controlling arm, whereby the tens gear segment is liberated and permitted to be pulled downward by its spring 27.
