While the invention as disclosed in the parent application is embodied in a machine for adding numbers, the principles and construction may be usefully employed in machines for various other purposes.

' Therefore, in the accompanying drawings and description, the adding mechanism is omitted. I

Like letters of reference refer to like parts in the several figures.

stantially 'in line I avenues General construction 1 represents the main frame of the machine which may so as to support the working parts of the machine.

5 (Fig. 2) represents the main gear segments, which in the parent application are utilized to operate suitable accumulating mechanism and which in the present instance are used to move type carriers to position their various types. Each of these gear segments is provided at its lower end with a rearwardly projecting arm 6 which is-pivoted lgosely on a transverse supporting rod 7.

This rod is mounted with its ends on the upper ends of two rock arms 8 which turn loosely with their lower ends on a transverse rock shaft 9. The rock-arms 8 are connected bya transverse bar 10 which compels the two arms to move back and forth together. In the normal position of the gqear segments when the machine is at rest tese segments are retractedrearwardly and are elevated.

The gear segments are yieldingly held backwardly by means of springs 11 (Fig. 9) connecting the rock-arms 8 with a stationary part of the frame. Fig. 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. The gear segments are moved forward by means of a shifting rock-arm 1.3., which is preferably secured to the right hand rock-arm 8 and projects rearwardly. 'lUponraising the shifting rock-arm 13, the rock-arms 8 and gear segments 5 are swung forwardly while upon swinging the shifting rock-arms downwardly, the rock arms 8 and gear segments 5 are swung rearwardlv.

1a (Fig. 2) represents a cam whereby the gear segments are moved forward. 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, 7, and 14:. Upon swinging the rocking frame 15, so that the cam I l moves forwardly, the incline of the latter engages underneath the roller 18 and raisesthe arm 13, thereby moving the arms 8 forwardly. When the roller 18 has been raised to the top of the incline the concentric portion of the cam engageswith the roller during the continued forward movement of the cam and the latter does not shift the gear segments any further forward.

When the rear end of the concentric face 17 of the cam passes forwardly from underneath the roller 18, the constant pull of the springs he of any suitable construction an part of thero'ciiing'frame 15, as shown in Fig- 13 and the parts conroller 18 which lifts said incline, and at the end of the backward movement of the cam,

the latter clears said roller and drops behindthe same, as shown in Figure 2, preparatory to again raising 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.

ront end of the'camis limited by means of a lug l9 projecting from the side of the cam engagi g with a slot in the adjacent ures 14 and 32.

The rocking frame 15, is secured with its lower portion to a transverse rock-shaft 20 journaled in the-main frameand provided outside of the frame with a hand crank 21, as shown in Figure 14, whereby this shaft is rocked and the parts connected therewith are operated. 1

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 loosely at its rear ends with the transverse rod 7 by lifting plates 23. 24 represents two shifting arms which are mounted loosely at their rear ends on the rock-shaft 20 and which support at their other ends a transverse'bar 25 which transverse bar is connected at its ends, by two links 26, with the lifting platis 23, whereby upon raising the shiftin arms 24, the lifting bar 22'is caused to raise t e gear segments and the other parts connected therewith resting on said bar. Upon depressing the transverse bar 25, the lifting bar 22 is moved downward ly and the gear segments resting thereon are permitted to move downwardl with the bar until the segments are arrested Each of the gear segments is held in contact with the lifting bar 22 by a spring 27 which connects the arm of the segment withthe transverse bar 25. 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 in one end in a segmental notch 28 formed in the front part of the rocking frame 15, shown in Figrocking frame 15, this card ing shaft 20 constitute the main moved the gear yieldingly ures 2, 'Z, and 14, and its opposite end is arranged in a similar segmental notch 28, formed in a rocking frame 29 (Fig. 14) 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 operator universal operating fraine of the machine.

hen the machine is at rest, as shown in F lgure 2, the transverse bar 25 engages with the front side of the notches 28 in the rock ing 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 rocking frames are moved forward 1y during the first part of the movement inde pendent of the transverse bar 25. The latter remains at rest until the inclined front end 16 of the cam 14 has raised the arm 13 and segments, 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 moved forward the continued forward movement l 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 he are arrested. After the segments have been arrested in their downward movement, they remain in this position while the locking 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 05 from the rear end of the concentric part of tion.

30 represents a number. of elbow-shaped controlling arms, which form part of the devices whereby the downward movement of the 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 exten 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 1, 2, 'Z', 13, 33 and 34.. The rear end of the lower the uppermost as shown in Fi art of each controlling arm is mounted loosey on a transverse su porting bar 31, while the-upper end of its out or upright part is loosely connected with the up er portion of its companion gear segment. his loose connection permits the controllingarm and the gear segment to swing freely about their in dividual axes, but out of line, and also permitsthe gear segment to move forward and backward. In osition of the "controlling arms the same ear with their upper ends against a transverse stop bar 32, as shown in Figure 2, which limits the upward movement of thesearms. 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 with a stop lug 34, both of which lugs project toward the left and are preferably stamped out of one piece with the controlling arm.

The operation of the recording devices is controlled by a number of elbow-shaped key levers which are arranged side by side and pivoted to a transverse Each key lever is provided with anlower actuating arm 36 which projects forwardly and an upper sto arm 37 which projects upwardly along the eft hand side of one of the controlling arms and gear segments, as represented in Figures 2, 7 13 and 33. Each of these key-levers is provided on the 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 key-lever is in its fully retracted position,

ure 2. When the parts are in this position, t e 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. and the rocking frames are turned forwardly for depressing the gear segment, the spring 27 of this segment will be strained without, however, shifting the segment. At the end of this forward movement of the rocking segments, the roller 18 of the rock arm 13 drops ofi from the rear end of the cam 14, the gear segment islmoved rearwardly, and then the rocking frames move backwardly.

The upper arm of each key lever is provided on its front side with a vertical series of differential stop shoulders 39, which are arranged ste fashion and extend from the upper end 0 this arm downwardly and for wardly thereon or 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 forward into the path of the stop lug 34 on the controlling arm. The stop shoulwhich are arranged parallel supporting rod 35.

ders are arranged difierent 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 plug of the controller arm, the latter and the gear segment connected therewith may be arrested at diiferent 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 levers are so arranged that the distance from the stop shoulders to the path of the stop lug 34' gradually grows less from the uppermost stop shoulder to the lowermost stop shoulder. By turning the key lever forward more or less and moving one or the other of its stop shoulders into the path of the 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.

M az'n number key mechanism 40 represents the main ke s whereby the key levers of the main recor ing mechanism are operated, and which are guided with their depending stems in the top 41 and bottom 42 of the key-board. 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 eight keys and represents fractions of one-eighth of a cent, the next column toward the left contains nine keys and 'reprresents cents and the remaining columns of eye toward the left each contains nine keys and re resents progressively higher orders of num ers according to the decimal system, so that the registering keys in the last or left hand column represent hundreds of thousands of dollars.

The lowest number 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 toward the front end of the keyboard.

Each of the registering keys is yieldingly 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 bearing with its lower end against the bottom of the keyboard. The upper movement of each key is imited by a shoulder 44 formed on the up or art of its stem and engaging with the un erside of the top of the key-board, as represented in Figures 20 and 22.

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 arm 0 each key lever tances. The keys having the lowest numbers j,

bear against their respective key levers nearest the pivot and consequehtly the levers are thereby thrown the greatest distance, and the uppermost stop shoulders are shifted into the path of the stop lug 34 of the respective controlling arms. The throw of each key lever upon pressing any one of its keys is so adjusted that the proper stop shoulder on its upper arm-is moved into the path of thestop lug 34 of the controlling arm and the downward movement of the respective gear segment is arrested after having turned a number; of spaces correspondin to the number of the key which is depresse 'A slip or loose connection is provided between the controlling arms and the gear segments of higher denominational order which in the parent application is utilized'for car,- rying in the accumulating mechanism, However, in the present application such sli connection might be dispensed with an any means provided whereby-the gear segments may drive the controlling'arms.

As shown in Figures 1, 2,and 7, each controlling arm is provided at its upper end with upper andlower guide faces 47 and 48 and its lower guide face is engaged by a lower guide lug 46 on the adjacent gear segment, the same as in the coupling between the controlling arm and the segment of the initial registering device.

When a key lever is actuated and the machine operated, the controlling arm related to said key lever descends until stopped by said key lever, and during the last portion of the operation the controlling arm and key lever are returned to their normal positions.

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 ofthe controlling arm and locks the latter against downward movement. The return movement of each key lever is preferably effected by a spring 60 which connects the upper arm of the key lever with the transverse shaft 9, as shown in Figures 2 and 7, or some other convenient part of the machine. The lower 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 sufiicient to raise the arm, but it is preferable to employthis lower guide lug 46 on the gear segment because it compels the arm to raise 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.

Recording mechanism For the purpose of recordin numbers, a recording mechanism is provi ed which is constructed as follows 140 (Figs. 1, 2, 7 9, 14, etc.) represents 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 sheetor .other article is placed which receives the record. 141 represents a number of'type se ments 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 t e controlling arms are pivoted. Each of these type segments is provided at its rear end with a segmental row of. pa carriers 142 which are capable of moving radially back and forth on the type segment.

Each of the type carriers is provided at its rear end with a type and is guided upon the type segments by means of screws or rivets 143 (Figs. 3, 29 and 30) secured to the type carrier and arranged in radial slots 144 formed in the type segment. Each of the type carriers is held in its inward. or retractmg 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, as shown in Fi ures 29 and 30. Upon raising or lowering t e type segment any one of its type can be broughtto the printing point or line, and upon striking the back or lnner 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 platen.

After'the carrier has received the blow for driving the same against the platen, the car rier is again quickly retracted to its innermost position by means of its spring.

Each of the type segments is connectedwith one of the controlling arms, so that upon depressing a controlling arm and the re 'ster-f mg gear segment connected. therewit the companion type segment will 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 the key-board and in order to produce a compact record, the printing segments are arranged closer together than the keys. .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 andv33. The connecting arms of the central controlling arms 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 gradually increasing from the central type its type on 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, the zero type being at the upper end of the series and the progressively higher digits arranged in their order downwardly from the zero type. When the registering gear segment is. in its highest position, 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, its companion type segment is raised proportionately and presents a correspondingly higher numbered type to the printing point.

147 represents a number of hammers whereb the type carriers are struck for driving t e 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 types 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 polnt and produces an impression of laten. The several hammers are pivoted on t e transverse rod 12, arranged in rear of the segments; 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 ends 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 t pe carriers which are at the printing point. ne of these pawls is arranged adjacent to each hammer 'and pivoted loosely at its lower maaeae upper end of the hammerd pawl with a lower trip lug or shoulder 156 and an'upper trip lug or shoulder 157. l/Vhen the parts are at rest, the hammer pawl 153 is raised into ts highest position and the hammer is in its normal position with its'lower trip lug 156 below and in. rear of the hook of the hammer pawl and with its upper shoulder 15'? 1n rear of the trip face of the hammer pawl, as represented in Figures 2, 3 and 41.

Upon shifting the hammer pawl rearwardly, while the parts are in this 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 the last portion of the downward 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 bar 151 now rises and carries the hammer pawl into its highest position, preparatory to again engaging the hammer for depressing the same.

158 (Fig. 3) 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 these arms is arranged adjacent to each hammer pawl, as shown in Figures 3, 6 and 41, and is pivoted at its lower end on the trip bar 151, and its upper end is provided with a roller or projection 159 which bears against a hammer cam 160 on the lower part of the adjacent type segment, as shown in Figures 3 and 7. This hammer cam is provided at its upper end with a receding or low portion, an inclined portion arranged below the low portion, and a concentric or high portion arranged below the inclined portion. Each shifting arm 158 is moved forwardly and its'roller is yieldingly held in en agementwith the adjacent hammer cam y a spring 161 connecting said arm with a cross bar 162 secured to the rock arms 152, as represented in Figures 7 and 8. The backward movement of each hammer pawl with reference to its companion shifting arm, is limited by means of a stop163 secured to the upper portion ofthe hammer pawl and engaging with the front side of the shifting arm, as represented in Figures 3, 5 and 41.

Each hammer pawl is yieldingly held in its rearmost position with reference to its shifting arm by means of a C-shaped spring 164 secured with its ends, respectively, to the hammer pawl and its shifting arm, as shown in Figures 2,3 and 41. In the lowermost posi-" hook has passed below. this shoulder; but instead, the trip face of the hammer pawl slides idly against the shoulder 156 without retracting the hammer, whereby no impression of the.

particular type at the printing line is produced. 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, movesthe 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 downward movement 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 backwardly into 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 shift ed into an operative position for producingan impression, if the type segment is raised one or more digit spaces and presents any one of its digits higher than zero to the printing line.

Automatic printing of zero 165 (Figs. 3 and 41) 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 Figures 3, 7, and 41, and extends laterally toward the ri ht therefrom in front of the shifting arm 0 the next lower hammer pawl, as represented in Figure 22. If any one of the printing segments 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 hammer 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 book is carried back wardly 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, 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 thetransferiinger 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 effectedautomatically 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 printin line.

Only the ciphers elow the highest digit in the number to be recorded are thus printed automatically because the printing of a digit depends upon the upward movement of a printing segment, thereby avoiding the printing of ciphers ahead of the highest digit in the number to be recorded. The hammer shifting device of the segment' which prints the numbers representing units of cents is, preferably, not provided with a transfer finger to operate on the hammer shifting device of the segment which prints fractions of a cent, because it is proper that the space to the right of the lowest integer shall remain blank when no integer is recorded therein.

The trip bar 151 is raised by one or more springs 166 (Fig. 8) which connectthis bar with the transverse rod 12, and the upward movement of the bar 151 is arrested when of the rocking frames, the front ends of their the hammer o crating pawls reach their highest position y a transverse bar 107 (Figs. 8, 9, and 16) 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 up 'er and lower shoulders.

In the. lowere position of this hook its notch engages with a cross bar 169 which is connected with the rock arms 24, as represented in- Figures 2 and 7, so that the hook and the hammer operating devices connecting therewith are actuated from the rockin frames 15 and 29, through the medium 0 the rock arms 24. In the rearmost position notches 28 bear against the front side of the bar 25 to which the gear segments are yieldingly connected, and the cross bar 169 bears against the rear or upper shoulder of the IlOtClQl of the hook 168, as represented in Figure U on swinging the rocking frames forwar 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 bar 25, so that thereafter this bar is carried downward 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 down idly 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 downward 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 ham mers, 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 delievered after the type segments have been shifted into their proper position for recording the respective number.

The hammers do not follow the type carriers to the end oftheir outward movement but are stopped short, after delivering a blow against the inner ends of the carriers by their depending arms 150 engaging with a rubber" facing 170 on the cross bar 167, as

shown in Figure 3, so that the type are moved outwardly by the impact of'the hammers and are then returned by their springs '50 as to clear the printing surface.

N on-pn'nt mechanism When it-is desired to render the recording mechanism ineffective, 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 hammer operating devices. The con ling hook is disengaged from the cross bar y means of an elbow lever 171 secured to a transverse rock shaft 172. The lower arm of the elbow lever is connected with the shaft 20 by a spring 17 3, whereby the lever and the shaft carrying the.

.same are turned in the direction for disconnecting the up er arm of the lever 171 from the hook 168, t ereby permitting the latter to engage the bar 169. v

174 (Fig. 9) represents an elbow lever arranged below the bottom of the ke board and having its lower arm connecte by alineor cord 17 5 to the upper arm of the elbow lever 171. 176 represents a shifting key having adepending stem which is guided in the top and bottom of the key-board'and which engages with its lower end a ainst the upper arm of the elbow lever 1 4. Upon depressing this key the elbow lever 174 is turned in the direction for moving the rock arm 171 into engagement with the cou ling hook 168 4 and disengaging the latter rom the cross bar 169, thereby throwing the recording mechanism out of gear. Upon releasing the key 17 6, the rock arm 171 is permitted to swing backwardly and allow the cou ling hook to engage with the cross bar 169, t ereby throwing the recording mechanism into gear.

Duplicate painting by counterpart types For the purpose of permitting the numbers to be printed in duplicate, for instance, when it is desired to print an amount on a bank check, and the same amount on a stub, the machine is provided with a mechanism which is constructed as follows:

1410 (Fi s. 1, 14 and 16) represents a number of dup icate printing or type segments which are arranged transversely in line and preferably toward the right of the main printing segments 141, and which are pivoted loosely at their front ends on the supporting rod 31. One of these duplicate number printing segments is provided for each of the main number printing segments, and each duplicate segment is connected with its companion main segment by a U-shaped frame (Fig. 18) which frame is connected by the upper ends of its arms 189 to its duplicate and main segment and has its crossbar 190 arranged transversely below the intervening segments, as shown in Figures 1, 2, 4, 7 and 18., The cross bars 190 are arranged sufficient distances below the segments so. that each pair of connected main and duplicate .to and constructed the same as the type carriers of its companion main segment and each of these duplicate segments is provided with a hammer operating device which is constructed the same as the hammer operating devices of the main segments, and the same description and letters of reference, therefore apply to the details of both the main and duplicate printing segments.

Duplicate printing inoperative If it is desired to duplicate only the small numbers no duplicate segments need be provided for the higher numbered printing seg ments. For the purpose of throwing the duplicate printing mechanism out of gear when. it is not desired to print the numbers in duplicate a horizontal movable bar 191 (Fig. 19) is providedwhich I is arranged transversely in rear of the hammer pawls of the duplicate printing segments and which is provided with a number of forwardly projecting lugs or stops 192, as represented in full lines in Figures 4, 16 and 19. Upon shifting this bar, so that its stops stand in rear of the duplicate hammer pawls, as shown in full lines in Figure 19, these pawls are prevented from being swung rearwardly and operating the hammers. Upon moving this bar so that its stops clear the duplicate hammer pawls,- as represented by dotted lines 192, Figure 19, these pawls are free to be swung rearwardly by the segment cams 160 into engagement with the hammers, so as to retract the same during the downward movement of the pawls for producing an impression of the types of the duplicate segments which are at the printing line. A suitable key or finger-piece is provided, by the operation of which the bar 191 is shifted into effective position.

Horizontal ruling or cross ruling upon the sheet or surface which receives the record, the following mechanism is provided:

193 (Figs. 2, 7, and 17) represents the lowermost type carrier of each of the number printing segments, each of which is provided at its rear .end with a horizontal ruling type. Each of these ruling type carriers is constructed the same as the number type carriers with the exception that the front end of each ruling type carrier is widened horizontally, preferably, in both directions in the form of the letter T, as shown in Figure 17 and the ruling type extends transversely from end to end of the widened ,part of',this carrier, so that the ruling types, when placed transversely in line and driven against the platen, will produce a practically continuous line transversely on the recording surface. Each of the number key levers is provided on the front side of its upper arm with a ruling stop or shoulder 194, which is arranged one space below the lowermost number registering stop or shoulder 39.

Upon swin ing the key levers, so as to bring their ruling s oulders 194 into the path of the lugs 34 of the controlling arms,-.the latter together with the gear segments connected therewith are depressed upon moving the rocking frames 15 and 29 forwardly, until the stop lugs 34 of the controlling arm engage with the lowermost or ruling shoulders 194 of the key levers. When the controlling arms reach this lowermost position, the printing segments connected therewith have i been raised to their highest position and present The key levers are turned simultaneously for bringing all of their ruling shoulders simultaneously into the path of the stop lugs of the respective controlling arms by means of a rocking plate 195 which is arranged transversely in front of the lower arms of the key levers and overhangs the front ends thereof, as represented in Fi ' ures 2, 7 and 22. This rocking plate is secure to a transverse rock shaft 196 which is 'ournaled in the frame .key is provided with a depending stem which is guided in the top and bottom of the keyboard and which engages against the rear end a of a 'rock arm 199 projecting rearwardly from the rock shaft 196, as represented in Figure 9. For the purpose of producing horizontal.

Upon .depressing this key, the rocking plate 195 is turned in the direction for depressing the front arms of all. the number key levers and bringing the ruling shoulders 194 on the upper arms thereof into position for arresting the type segments during their upward movement when the ruling types arrive at the printing point.

In order to prevent the gear segmentsfrom moving forward during the crossruling operation the position of the cam 14 is reversed at the same time that the plate 195 is depressed.

The mechanism whereby cam 14 is reversed is constructed as follows:

The cam 14 drops into its operative position by gravity, and is provided in rear of its pivot with a tail 75 which is depressed when it is desired to lift the cam into its inoperative position.

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, as shown in Figures 2 and 7. 82, Fig. 9, represents a line or cord connected to lever 76 above its pivot, and 1961 represents a line or cord for operating cord 82.

In the parent application several 'cords operate the cord 82, but for the purpose of the present application, the members-82 and 1961 might be a single cord.

The cord 1961 is connected to arm 1960 fast on a shaft 196, operable by the cross rule key 198.

When it is desired to produce horizontal ruling on the recording surface, the key 198 is depressed, thereby raising the cam 14 into an inoperative position, and moving all the number key levers with their ruling shoulders 194 into the paths of the stop .lugs of the controlling arms. Upon now moving the handle 21 (Fig. 14) forwardly the consequent rocking of the frames 15 and 29 first causes the gear segments and their controlling arms to be moved downwardly until arrested by the rulin shoulders 191 of the key-levers, in whic position of the parts, the printing segments have been raised with their ruling types to the printing line. The continued forward movement of the rocking frames operates the hammer-tripping mechanism and produces an impression of the ruling types on the record surface; upon moving the handle 21 backwardly the parts resume their normal position.

Instead of producing cross ruling by means of a transverse row of independent types, this ruling ma be effected by a separate ruling late 200 Fig. 37) which extends transversey along the entire width of the space to be ruled. In this modified construction of the horizontal ruling device, the ruling plate may be supported by upright arms 201 from a transverse bar or shaft 202, and may be operated by any suitable mechanism.

Vertical ruling Mechanism is provided whereby vertical ruling may be roduced on the recording surface, this mec anism being constructed as follows: v l

203 (Figs. -1-,-14,.-16, and 28) represents an upright ruling lever which turns loosely on the supporting bar 12 and which is arranged between the dollars and dimes printing segments: The upper arm of the ruling lever is provided with a vertical rulingblade 204 (Fig. 28) which is arranged close to the platen when in its upper position. The ruling lever is yieldingly held in this position by means of a spring 205 connected with the lower arm of the ruling lever and the movement of thelatter toward the platen is limited by the engagement of its lower arm with the rear side of a rubber buffer 206 on the cross bar 167 similar to the rubber 170. 207 represents a pawl whereby the ruling lever is retracted and then released for permittingthe same to deliver a blow against the recording surface for producing a vertical ruling impression thereon. This pawl is pivoted at its lower end on the cross bar 151 and is yieldingly held with the hook 208 on its upper arm in engagement with a shoulder 209 on the ruling lever by means of a spring 210 which connects the lower arm of the ruling lever with the rod 162.

In the uppermost position of the bar 167 the ruling pawl engages the shoulder of the ruling lever and upon depressing this bar, the ruling lever is pulled downward by the ruling pawl. During this downward movement of the ruling lever and pawl, the front side of this lever engages with the upper arm of the pawl and gradually crowds the awl forward until the pawl is disengaged rom the shoulder of the lever. When the ruling lever is thus released from the pawl, the lever is quickly turned by the spring 205 in a direction for throwing its upper arm upwardly, whereby its blade delivers a blow against the recording sheet or surface on the platen and produces a ruling im ression thereon. During the last portion 0 the subsequent upward movement of the ruling pawl 207 its hook again engages over the shoulder of the ruling lever. This construction of vertical ruling devices produces the vertical ruling in sections by successive blows of the ruling blade.

If desired vertical ruling may be produced by holding a stylus or lead pencil 211 against the recording surface by means of a stationary holder 212, as represented in Figure 38, whereby continuous ruling is produced on the recording surface or sheet as the sheet is fed past the same.

Vertical ruling may also be produced by a ruling disk 213 arranged to bear with one side against the recording surface and an inking wheel 214 supplying the ink to the edge of the ruling disk, as represented in Figure 39.

' Word printing mechanism For the purpose of permitting words to be locking lug printing segment of the main number record ing mechanism. This segment is provided with anumber of radially movable carriers 1420, (Figs. 8 and 16) which are constructed the same as the carriers of the number print- 1 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 3600, Figure 8,'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 3400 of a controlling arm 3000; and lever-3600 is also provided with a locking stop or shoulder 3800 which is adapted to be engaged by a 3300 on the controlling arm, as represente in Figure 8. The controlling arm 3000 is connected with the word-printing segment by a connecting bar 1460. The stop shoulders on the upper arm of the wordkey lever are so arranged that upon swinging this lever so as to carry difierent 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 to the printing point which corres onds with the shoulder or stop on the wordey lever.

The upward movement of the controlling arm 3000 is limited by its rear locking lug 3300 engaging with the stop bar 32 which arrest the upward movement of the controlling arms 30 of the auxiliary recordin mechanism. The downward movement 0 the controlling arm 3000 and the simultaneous up ward movement of the word printing segment is effected by a spring 215 which yieldingly connects this arm with the bar 25 to which the registering gear segments are connected.

216, Fig. 1, represents a row of word-keys having depending stems which areguided in the top and-bottom of the keyboard'and which engage against the upper side of the front arm 3600 of the word ey lever at different distances from the fulcrum thereof. Upon depressing any of the word keys, the work-key lever will be turned the pro er distance to bring its proper stop shoul or into 'ent invention.

3601 (Figs. 9 and 22) and 3701 (Figs.'1, 9

the path of the stop lug of the companion controlling arm and arrest the word-type segment during its upward movement, when the word-type 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 numbers by the numbering printing segments, is effected. The word-types are driven against the platen by a hammeroperating 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.

Auxiliary printing mechanism .structed as follows 5000 (Figs. 1 and 25) represents a number of auxiliary gear segments which are mounted on the transverse rod 7 and are movable forward and back therewith. Each gear segment 5000 is connectel with a res ective controlling arm 3001 (Figs. 1 and 25) in substantially the same way that the main gear segments are connected to their controlling arms, except that the auxiliary controlling arms are capable of moving independently of their correlated gear segments. This last feature, however, forms no part of the presand 25) represent the lower and upper arms respectively of auxiliary key levers which are operated by auxiliary keys 401 (Fig. 1),

and which control the operation of the auxiliary recording mechanism.

The detail construction of. the gear segments, printing segments, key levers, and the parts co-operating therewith of theauxiliary recording mechanism, is substantially the same as the construction of analogous parts in the'main recording mechanism, except as elsewhere mentioned, and the same letters of reference are therefore employed in most cases tov denote like parts in both of these sets of mechanisms.

In the drawings, two auxiliary key levers and related parts are shown, but additional recording devices may be emplo ed if it is desired to increase the capacity 0 the machine. H In the auxiliary recording mechanism the gear segments are not rovided with lower stops 46 like those of t e gear segments of the main recording mechanism, so that the auxiliary controlling arms may move down-
