Application filed August 15, 1912. Serial No. 715,151.
To all whom it may concern Be it known'that I, FRANCESCO SKERL, a
citizen of Austria-Hungary, residing; at
Dayton, in the county of Montgomery and .State of Ohio, have invented certain new ries of levers adapted to be adjusted, preliminarily to determine an amount to be registered, indicated and recorded upon the completion of an operation of the register. In the construction of a register of the type above mentioned it is one of the objects of the present invention to have the manual adjustment of the amount levers merely predetermine the amount to be registered, indicated and recorded. The purpose of so constructing the register is to have the performance of the three functions mentioned occur during the operation of the register and wholly beyond the control of the operator.
A further object is to adapt the register for a segregate analysis of transactions by the provision of a plurality of totalizers capable of preliminary adjustment to establish a cooperative relation between any one of said totalizers and a common totalizer operating means.
Another object is to provide an improved form of transfer mechanism for the several totalizers.
A further object is to'provide suitable interlocking mechanism for preventing an adjustment of any of the amount levers while the special transaction lever for positioning the counters for operation isin a no sale or non-registeringposition and, further, to prevent the adjustment of the special transaction lever to its no sale or non-registering position while any of the amount levers is out of normal position.
Vith these and incidental objects in view, the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in the appended claims. and a preferred form of embodiment of which is-hereina fter described with reference to the drawspecification.

Fig. 3 1s a cross section of the entire machine looking to the left and showing one of the amount levers'together withv its connecting mechanisms for operating the positioned to talizer, and the indicating and recording mechanisms Fig. 4: is a detail front section of one of the amount levers showing the locking mechanism for holding the same in adjusted position. Fig. 5 is a cross section of the machine showing the connections for adjusting the multiple counter reel. Fig. 6 is a side elevation of the printing mechanism. Fig. 7 is a detail-cross sectional view of the printing mechanism showing the automatically reversible feed mechanism for the inking ribbon. Fig. 8 is a rear elevation of the printing mechanism. Fig. 9 is a detail view of the cam and connections for controlling the locking devices for the amount levers. Fig. 10 is a detail view of ment of the levers, While predetermining the amount to be entered upon the totalizer, would directly' operate on the connections for indicating and setting up the printing mechanism. In the present case, however, all of the general operations of the machine have been removed from the control of the operator and an adjustment of one of the amount levers will merely predeterminethe amount to be registered, indicated and recorded, the actual performance of such functions taking place upon an operation of the main operating mechanism and wholly beyond the control of the operator.
The machine is provided with a main operating handle adapted to be given two complete revolutions at each operation of the machine. Through-the medium of the gearing shown in Fig. 12 the rotary movement of the handle is transmitted to two main operating shafts l6 and 17, each of which is adapted to receive one complete revolution at each operation of the machine. The shafts 16 and 17 carry the operating parts and connections for giving a complete operation to the working parts of the present machine, as will be hereinafter described.
The machine is further provided with a series of adjustable amount levers 20, exact duplicates in form, and each comprising a part 21, pivotally mounted upon a stud 22 carried by a section 23 on the main frame of the machine, and a part 24 mounted to slide upon the part 21 and being connected thereto by slot and pin connections 25,. (See Figs. 3 and 4). The part 24 carries on its upper and outer end a handle or knob 26 and an index pointer 27. The part 24 also carries a lug 28 which is adapted to engage in any one of a series of notches 29 formed in a locking plate 30 rigidly mounted on the section 23 of the main frame. The lug 28 is normally held in engagement with the uppermost notch 29 of the plate 30 by the action of a spring 31 interposed between the lug 28 and a flange 32 formed on an upward extending arm of the part 21.
Nhen it is desired to adjust an amount lever 21, the operator grasps the handle 26 and pushes the part 24 inward to disengage the lug 28 from the uppermost locking notch 29. This pushing in of the handle 26 is permitted by reason of the slot and pin connec tions 25 before mentioned, and the operator is then permitted to move the lever down along a scale on the front of the register until the index pointer 27 rests opposite the number which it is desired to register. The handle 26 is then released and the outer end 24 of the amount lever will spring upward and outward under the action of the spring 31 and the lug 28 will again engage in one of the locking notches 29.
The amount lever is held locked in its adjusted position until an operation of the main operating mechanism, when it is released and restored to normal zero position. Through the restoring movement the amount represented by the position of adjustment, which was primarily given to the amount lever will be entered upon one of a series of totalizers 33.
The totalizers 33 are carried by a rotatable frame 34 and previous to an operation of the mainoperating handle the carrier 34 is adjusted to establish a cotiperative relation between any one of the series of totalizer elements 33, and operating racks 35 forming part of the members 21 of the amount levers. Upon an operation of the main operating mechanism pinions 36 of the selected totalizer will be caused to mesh with the teeth of the racks 35 of the amount levers and when the amount levers are released and restored to normal position it will readily be seen that an operation of the totalizer will be effected to extents commensurate with the preliminary adjustment of the amountlevers. The mechanism for positioning the desired totalizer and for causing the totalizer pinions 36 to engage with the registering racks 35 will be hereinafter described.
In order to prevent any attempted readjustment or accidental displacement of the amount levers after the operation of the main operating mechanism has been begun, suitable mechanism is provided for holding the lug 28 positively in engagement with the locking notch 29 corresponding to the position to which the registering lever had been adjusted. This positive locking means comprises a plate 37 pivotally carried by a pair of hangers 38 pivoted on the section of 16 and carrying an anti-friction roller 46 playing in a groove 47 of a box cam 48 rigidly mounted on the shaft 16. The for mation of the cam groove is such that immediately upon the rotation of the shaft 16 and box cam 48 in the direction of the arrow shown in Fig. 9 it will cause a downward movement of the pitman 44 and a consequent movement of the rock shaft 42. The movement of the rock shaft 42 will cause the hangers 38 to be swung downwardly thereby forcing the plate 37 forwardly to cause the rearmost wall of the slot 39 to engage the under side of roller 40 and thereby hold the lug 28 positively in'engagement with the locking notch 29.
The locking of the levers in their position of adjustment is merely momentary and continues only during the operation of engaging the positioned totalizer with the racks 35. As soon as this engagement is effected the cam 48 will have been rotated to an extent sufficient to rock the shaft 42 .in the opposite direction so as to cause the constant mesh g mme given the amount lever, through the medium of the racks and the totalizer pinions 36.- 1 The restoration "of the amount levers .to normalzero position is efiected in the fol-- Each member 21 of the lowing manner: amount levers (see Fig; 3) is. a rack portion rovided with Pivotally carried on the segment 50; is a pawl 51 having one arm engagmga p1n=52 carried'by the rack- 49 when the amount lever is in normal zero position. The pawl 51 is provided with a spring 53 whi h nor face of the disk 55 of least radius;
is provided with a locking shoulder 56.;
mally tends to rock said pawl about" its pivot, but by reason of the engagement of the pawl with the pin 52 as aforesaid, such rocking movement is prevented. The pawl 51 is providedwith a locking projection 54, which in the normal position of the partsas shownxin Fig. 3, is held out of engagement with a disk 55 fast on'the operating shaft 17. At each operation of the machine the disk 55'is adapted to be given a single rotation inthe direction of the arrow. It
will readily be seen that when the amount lever 20 is moved downwardly to any one of its possible positions of adjustment the number 21 of the amount lever will be rocked about its pivot 22-and through the medium of the rack 49, the segment '50-will be rocked about theshaft 1 7. When. the racks 49 and thesegment 50 are so moved the pawl 51 and the pin 52 will move away from each other and under the action of the spring 53 the said pawl will be caused to rock about its pivot so as to cause a locking projection 5413f said pawl to "rest on the When the levers 26 have been adjusted and the machine is operated, the parts just described become elfective immediately fol-" lowing the release of the amount levers.
Upon the operation of the machine it will be readily seen that the disk 56 will be given one complete rotation durin which move- -ment the shoulder of sai disk will en-' gage the locking projection 5 1 of the pawl 51 and thereby carry the segment 50 with-it- When the segment 50 is so moved it will readily be seen that the action will tend to restore the amount lever to normal zero position through the medium of the constant engagement of the rack 49 with the segment 50. As soon as the rack 49 and segment 50 reach their normal positions as shown in Fig. 3,-the pin 52 .will again engage the pawl 51 and through the engagement rock said awl'about its pivot to disengage the lockmg projection 54 of saidpawl from the in mesh with the rack 35 during the restorlooking shoul ers of the-disk :55. 'At this point, in the o eration of the machine, the
cam 48 (Fig. 9 will have reached the igosh;
tion when it will again rockthe sha to permitthe outer portion 24 of the-f6 1 the lug 28 with thelocking plate 30 to hold I the amount amount-flever to move outward to engage lever in its normal zero positlon.
As the positioned totalizer is constantly" ing movement of the amount lever, it will thus be seen that the; totalizer will be oper-" ate'd to an extent appropriate to the exten of restoration of the amount levers.
Totaliz'er setting meohanism.-The meek-' anism for estabhshing coiiperative relation between any desired one of the totalizersBS and the-common set of actuating racks 35 will now be described. The means for posi-- tioning the desired totalizer relative to the actuating racks comprises a setting lever 57 pivoted at 58 to a section of the. main frame.
The lever 57 carries a curved rack 59 the teeth of which mesh'with a pinion 60 mounted on a counter'frame comprising two side arms 61 'bifurcatedat either end to straddle the pivotal point 58 of the lever 57 and a horizontal rodf62 mounted in a pair of standards 63 mounted on the'base of the machine. The pinion 60 is of double width and, besides meshing with the'teeth of the rack 59, also meshes with a companion pin ion 64: fast upon a shaft 65 mounted in a counter elevating frame. On the shaft 65 is mounted the rotary carrier 3 1 which carries four sets of totalizer elements 33 It will thus be seen thatwith the mechanism izer "frame 34120 position one of the totalizers 33 in coiiperativerelation with the actuating.
racks'35.
In order temporari y to lock the adjusting lever 57 in any position of adjustment, the lever 57 carries locking means adapted to cooperate with a series of notches 66 formed in the locking plate 67 rigidly mounted, on the frame of the machine; The locking means comprises a plunger 68' having a head 69 which is adapted to enter any one of the above mentioned notches 66. The plunger 68 is carried by twohangers 70 and 71 piv-:
oted on the lever 57. The hanger 71 is of bell crank formation, an upwardly extend-- ing arm being adjacent the handle or knob of the lever 57. When it is desired to adjust thetotalizer carrying member 34, the operator should grasp the handle of the lever 57 and rock the bell crank 71 about its pivot whereby to disengage the head 69 of the plunger 68 from the locking notches 66.
The lever 57 is then free to be moved downany of its proper positions of adjustmentv means are provided for locking the main operating device until the lever 57 is moved to one of its proper positions. This means .comprises a curved plate 72.which is curved on the are of movement of the head 69 of the locking plunger 68. The plate 72 is mounted on two hangers 73 and 74 pivoted at 75 and 76 respectively to the main frame of the machine. Pivoted to the hanger 74 is a rearwardly extending link 77 having an elongated slot 78 surrounding the shaft 16 which is thus adapted to su port the rear end of the link. The link 77 carries a'lug .79, which in the normal position of the parts, as shown in Fig. 1, is in alinement with a notch 80 formed in a cam 81 which is rigidly mounted on the operating shaft 16. The link 77 extends rearwardly at the shaft .16 and is pivoted at 82 to a lever 83, which is rigidly mounted on a rock shaft 84, for a purpose to be hereinafter described. The lever 83 extends downwardly from its pivot, and connected to its lower end is one end of the spring 85, the other end of which is connected to an eye 86 formed on the base of the machine. The purpose of 'the spring 85 is normally to hold the link 77 and the hangers 73 and 74 and the plate 72 in'forward position with the lug 79 out of locking engage- 'ment with the notch 80 and the cam 81. The head 69 of the locking plunger 68 extends laterally and is adapted to ride on the forward surface of the curved plate 7 2 when the bell crank 71 is rocked to disengage the locking plunger 68 from the locking plate 67. The extended portion of the head 69 of said locking plunger will force thecurved plate 72 rearwardly to rock the hangers .73 and 74 about their pivots thereby to force the link 77 rearwardly to cause the lug-79 carried thereby to pass into locking engagement'with the notch 80 of the cam 81. It will thus be seen that as long as the locking plunger 68 is out of locking engagement with the plate 67, the lug 79 will be held in locking engagement with the disk 81, consequently any operation of the machine, while the plunger 68 is in non-locking posi tion, is prevented and the entire machine is locked.
Immediately upon the beginning of the operation of the machine the positioned totalizer 33 is brought into operative engagement with the actuating racks 35. (See Fig.
locking plate 93 which 1.) Means for establishing the operatingengagement comprise a lever 87 pivoted on the shaft 88 and carryingat its rear end an .anti-friction idler 89 which at all times thereby to carry the side plates 61 upwardly to cause the pinions 36 of the positioned totalizer 33 to mesh with the actuating racks 35. The formation of the cam groove 90 is such as to maintain .the operative engagement of the positioned totalizer with the actuating racks during the entire time that the amount levers and their actuating racks are being restored to normal Zero position, during which restoration, as here before mentioned, the actual operation of the positioned totalizer is intended to take place.
In order to prevent any movement of the positioned lever 57 after the totalizer carrier has been elevated to engage the positioned totalizer with the actuating racks, the lever 57 is locked in its adjusted position. This lock is effected by a series of lock notches 92 formed in the forward side of the rack portion of the lever adapted to cooperate with the shaft 65, which carries the totalizer frame 34. Whenever the lever 57 is in one of its positions of adjustment, one of the notches 92 will be in alinement with the shaft 65*and as soon as the totalizer frame 34 is elevated as heretofore described,
locked against movement by the rotation of the cam disk 81 which when rotated will carry the notch 80 out of alinement with the lug 79,' thereby to prevent any rearward movement of the link 77. It will readily be seen that this will hold the head 69 of looking plunger 68 in engagement with a notch 66 until the operation of the machine is completed.
When the totalizer the pinion 60 will. be rack 59.
In order to prevent any accidental displacement of the positioned totalizer, there is provided a suitable locking means. (See Fig. 5.) This locking means comprises a is bifurcated at either end to straddle the pivot 58 and shaft 65. Locking plate 93 is formed with a locking tongue 94 provided with a bifurcation 95. enever any one of the totalizers 33 is in operative position, the supporting shaft 96, appropriate to said totalizer, will be in frame 34 is elevated,
izo
alinement with the bifurcation 95. Mounted upon the operating shaft 16 is a box cam .9
.formedwith a groove 98 into which extends an anti-friction roller 99. The roller 99 is carried by pitman 100 bifurcated at its upper end to straddle theshaft 16 and pivoted 'at its lower end to a lever 101 pivoted at 102 to the frame of, the machine. The lever 101 carries at its forwardend a roller 103 which extends in the bifurcation 104 formed in the lockingplaite 93. Immediately upon the beginning of the operation of the machine the formation of the-cam groove 98. will draw thepitman. 100 up-. wardly, thereby rocking the .lever 101 and causing the locking plate 93 to move downwardly to effect an engagement of the bifurcation 95 with the supporting shaft 96 of the positioned totalizer. This movement of the locking plate 93. is very slight, but is sufiicient to lock the adjusted totalizer in position immediately upon the beginning of the operation of the machine. The bifur;
. cation 95-is of sufficient length to permit the position.
shaft 96 to .pass up into the same when the totalizer carrying frame 34 is elevated.
Upon the completion of an operation of the machine the plate 93 will, of course, through the described connections,be caused to move upward to disengage the tongue 94 from the su] orting shaft 96.
. e formation of the restoringv disk 55, shown in Fig. 3, and of the cam' groove90, shown in Fig. 1, are such, withrelation to each other, that the cam groove 90 will first .cause the positioned totalizer to move upwardly into engagement'with the actuating racks and to maintain the engagement while the disk acts to restore the actuating racks 35 which had. been moved to normal Immediately following the re-. storation of all of the adjusted racks, the cam groove 90 will' cause the positioned totalizer again to be disengaged from the actuating racks "by lowering thev totalizer carrying frame. Transfer meckanism.'1n the "constructionof the present machine there provided an improved form of transfer mechanism for transferring amounts 'from the totalizer' elements of lower order to the totalizer elements of higher order. As shown in Fig. 3,-each element of the to'talizers 33 is provided. with an operating pinion 36 and a toothed alining disk 105. Coiiperating with each of the toothed alining disks 105 is a spring pressed pawl 106 which is at all times held in engagement with the teeth of said disks 105 by means of springs 107. In addition to the above all of the totalizer elements except the unit elements are provided with. a transferring projection 108 which is adapted upon'each complete rotation of the totalizer element-to engage a projection 109 carried'by a, pivoted pawl 110.
The pawl 110 is normally spring drawn to a position in which the projection 109 will be inthe path of the projection 108. An upwardly extending arm 111 of the pawl .110
normally stands just beneath aflange 112 formed. on a transfer .pawl 113 mounted on a rocking plate 114.
113 is provided with a forwardly extending finger 115 which is adapted to engage the alining plate 105, of the totalizer element of next higher order, and move the totalizer ivotally element a distance of one step. In the nor -mal position of the parts, however, the fin-' ger 115 is held out of engagement with the aliningdisk 105 byreason of the, flange 112' he pawl of the pawl 113 resting on the upper arm 111 of-the pawl .110. A spring 116 normally holds the described parts in this position.
As soon, however, as a totalizer ele ent has made a .complete rotation, its projec ion 108 will engage the projection 109 ofthe pawl v110and, upon the continued movement from osition of the totalizer,
the 9 to .the 0 element, the .projectron'109 will be forced .out of the path of the projection 108 and the pawl 110'will thereby be rocked against the action of the s ring 116 to withdraw the upper arm 111 rom beneaththe flange v112. This will permit the pawl 113 to .rock
about its pivot under the action of the spring 116 to bring the finger 115 into en-' gagement with the tooth alining disk, 105
of the totalizer element of next higher order.
The plate 114 carrying the pawl v113 is adapted then to be given a single reciprocation tbgeifect a movement of the totalizer 'wheel of next higher denomination a distransfer pawls 113. The operating means for the plates 114 are therefore common to all of the totalizers on the rotary carrier and when any totalizer is in operative position 1tS appropriate plates 114 are in a position to receive a single reciprocation upon an operation .of the machine. Each of the plates 114 carries a pin 117 and when a totalizer is in operative position its appropriate pins 117 are in alinenient with notches 118 formed in levers-119 which are pivoted at 120 to arms 121 all rigidly mounted on a rock shaft 122. The shaft 122 carries an arm 123 which is pivotally connected .at 124 to a pitman 125 adapted to be operated by a 'cam 126 shownin Fig. 11. Each lever 119 extendsrearwardly of its pivot and is pivotally connected at 127 to a pitman 128 which is adapted to be operated by a cam [129. There are provided a plurality of cams 129 similar in design but so arranged on the shaft 16. as to be effective in succession to operate the transfer connections in proper each other that the cam 126 will first draw sequence from lower to higher order in a manner well known in the art. The cam 126 and cams 129 are so timed with relation to the pitman 125 upward to rock a shaft 122, thereby to carry the levers 119 forward to cause the notches 11.8 therein to engage the pins 117. The levers 119 are held in this engagement for a brief period and during that time the cams 129 will act to force the pitmen 128 downward and thereby rock the levers 119 about their pivots 120, thereby to give a single reci rocation to each plate 114. The cams 129 wi 1 then rock the levers 119 to restore the plates 114 to normal position and the cam 126 will then again rock shaft 122 to withdraw the notch 118 of the lever 119 from engagement with the pin 117.
Indicating mechanism.-Arranged across the top of the machine are a series of indicators 130, each of which is of usual form and carries a plurality of indicia on its periphery. This form of indicator is well known in the art, and the mechanism shown "forms no part of the present invention, but will be briefly described herein. For a more detaileddescriptionof the parts constituting the indicating mechanism of the present machine, reference may be had to the copending United States application of Charles F. Kettering and William A Chryst, Serial No. 451,446, filed September 2 1908.
Each of the indicators 130 carries a pinion 131 which meshes with a gear segment 132, all of which segments 132 are pivotally mounted upon a shaft 133 extending across the machine beneath the series of indicators. (See Figs. 1, 3 and 5.) Each segment 132 is pivotally connected at 333 to a downward extending link 134. At 135 the link 134 is pivotally connected to one end of a floating beam 136, the other end of which beam is pivotally connected at 137 to the part 21 of the amount setting lever. Midway of its length the beam 136 carries a roller 138, the normal neutral position of which is in alinement with the pivotal point 22 of the amount lever.
In the normal position of the parts the indicator is held in adjusted position by the engagement of a locking pawl 139 with alining teeth 140 formed on the segment 132. The alining pawls 139 are rigidly carried by rock shaft 141. The rock shaft 141 is adapted to be .rocked by an arm 142 rigidly mounted thereon and pivotally connected at 143 to a downwardly extending pitman144, carrying an anti-friction roller 145. The anti-friction roller 145 extends into a groove 146 formed in a box cam 147 carried by the operating shaft 16. The shaft 16 is rotated in the direction of the arrow shown in Fig.
10 and it will readily be seen that immediately upon the beginning of an operation of the machine, the formation of the cam groove 146 will effect the downward move ment of the pitman 144 to rock the shaft 141 to an extent suflicient to withdraw the alining pawls 139 from engagement with the alining teeth 140 of the segments 132. How
ever, between operations of the machine and during the time that a preliminary adjustment is being given to the amount levers 20,
the pawls 139 are held in locking engagement with the segments 132.
' s As the parts are shown in normal position in *Fig. 3, it will readily be seen that when the amount lever 20 is moved downward to any of its positions of adjustmentfthe beam 136 will be rocked about the pivotal point 135. It will thus be seenthat when the beam'136 is so rocked, the roller 138 mounted thereon-will be carried out of it's normal neutral position. As soon as the operation of the machine is begun, the amount levers 20 are locked in their adjusted positions as herein before described. This will hold the pivotal point 137 rigid. The cam 147 (Fig. 10) will then be effective to disengage the 'alining pawls 139 from the segments 132 and the indicator 130, and all its connections are then free to move as well as the pivotal point 135. The roller 138 is then forced back to its normal neutral position by a pelican shaped cam plate 148 shown in Figs. 1 and 3. The plates 148 are rigidly mounted on a rock shaft 88'. As shown-in Fig. 2, the shaft 88 isadapted to be rocked by cam 149 carried by the operating shaft 16 through 'the medium of a pitman 150 pivotally connected at 151 -to an arm 152 fast on the shaft 88. As soon as the alining pawls 139 are disengaged from the segment 132, the shaft 88 will be rocked to cause the pelican plate 148 to move rearwardly so that either of its cam faces 153 will engage the roller 138 and thereby cam it back to normal neutral position. When the roller 138 is so moved it is momentarily held in position by a notch 154 formed in the pelican plate 148.
During the time that the roller is held in its neutral position by the notch 154, the alining pawl 139 will again become effective to lock the segment 132 in adjusted position. It will readily be seen that .as the roller 138 is midway of the length of the beam 136, the movement of the pivotal point 135 when the roller 138 is forced to normal neutral po-.
sition, will correspond in extent to the preliminary movement of the pivotal point 137 when the lever 20 .was adjusted previous to the beginning of the operation of the main operating mechanism. It will thus be seen that through the described connections the indicator 130 will be adjusted to a position corresponding with the position previously given tothe levers 20. I As soon as the segthrough the medium of the mechanism,
herein before described, the levers 20 will again be restored to normal zero position. This movement will again move the roller 138 out of normal neutral position, but this movement will have no effect on the indication as the pawls 139 will remain in locking effectiveness.
The indicating mechanism with the lever 57 for positioning the desired 'totalizer, is almost identical in form with the mechanism which has been described with regard to the amount levers and no further description will therefore be given of the mechanism in connection with the lever 57 except that the lever is provided with an additional indicator 155 extending across the top of the machine and having a series of faces 156 corresponding in number to the positions of setting lever 57 and adapted to bear a full word indication to indicate the totalizerwhich is in operative position. This indicator 155 is connected through the medium of a pinion 157 rigidly mounted on a shaft 158 which carries the indicator 155 with the indicator setting mechanism of the special setting lever 57. The pinion 157 is constantly in mesh with a mutilated gear 159, one section on which gear is constantly in mesh with a pinion 1131 loosely mounted on the indicator sup-- porting shaft. It will thus be seen that any movement of the special indicator setting mechanism will be transmitted through the connections described to the indicator 155 at the top of the machine. As shown in Fig. 1, the indicator155 is formed in two sections. This is for thepurpose of indicating to both the front and the back of the machine. As shown, the indicator 155 has five faces and it is therefore necessary to have a perpendicular face showing at both the front and back of the machine which faces should have marked thereon the same indication. Suitable connections-may be provided for furnishing a duplicateindication of amounts at both the front and back of the machine, and certain connections for performing this function have been shown in the drawings. These parts, however, have neither been numbered nor described, as they form no part of the present invention and a detail description of the same may be found in the before mentioned copending application.
Printing mechanism.As shown in Figs. 1, 3 and 5, each of the links 134 are alSO pivotally connected to arms 184 rigidly mounted on cross shafts 185 which extend to the left hand end of the machine. On the left hand ends of the shafts 184 are rigidly mounted arms 186. Each arm 186 has pivotally connected to it a downwardly extendin connection ing link 187 .which is pivoted atthe point 188 to a gear segment 160,- the teeth of which are constantly in engagement with a pinion 161 which forms an intermediate connection between the segment.160 and a pinion 162 fast to the right hand end of one of a series of nested sleeves 163. The sleeves 163 ex-' tend to the left and on the outer ends of said sleeves are mounted a series of type wheels 1-64. It will thus be seen that when the indicators 130 are moved to a position to indicate the adjustment previously given with the amount lever, its corresponding type wheel 164 will be adjusted through the connections just described to present at the printed point a number corresponding to the number displayed on its corresponding indicator.
As shown in Figs. 6, 7 and 8, the type wheels 164 are adapted to cause an impression on a detail strip 165 which is led from a supply roll 166 around a pair of rollers 167 and 168 to a receiving and feeding roll 169. The printing impression ismade through an ink ribbon 170 carried by a pair of spools 171 and 172, the impression means comp-rising a platen 173 carried by a platen arm 174 having a downwardly extending arm 175 carrying an anti-friction roller 176 extending into a groove 177 formed in a box cam 17 8 carried by the operating shaft 16. The cam 178 is adapted to be given a single rotation in the direction of the arrow in Fig. 6 at each operation of the machine, thereby to oscillate the platen carrying arm 174 to take an impression from the type wheels 164 immediately following their adjustment as hereinbefore described.
.When the platen arm 174 is so rocked it will effect an advance of the detail strip a single space by the following means. Rigidly mounted on the receiving roller 169 is a notched feeding disk 179. Carried on. a reciprocating plate 180, is a feeding pawl 181 which is spring pressed into engagement with the notches formed on the periphery of the disk 179. The plate 180 is arranged to be oscillated about the pivotal point, 182 through the medium of the link 183 connecting the plate 180 to the platen carrying arm 174. It will thus be seen as the platen arm 174 moves rearward to take an impression, the pawl 181 will be moved in a, counter clockwise direction over the periphery of the disk 179 a distance of one tooth and consequently, through the connec- -tions above described, when the platen arm .pair of spools 171 and 172 as shown in Figs. Y
6, 7 and 8. In order to bring a fresh portion of the inking ribbon into printing alinement after each operation of the machine, a feeding means is provided for feeding the inking ribbon from one spool to another. Means are further provided whereby when the complete length of the ribbon is fed from the one spool to the other, the direction of feed will be reversed so that there will be a constant feed of the ribbon in either one or the other direction at each operation of the machine.
The means for feeding the inking ribbon is as follows: Each of the spools 171 and 172 carries a toothed feeding disk 188 and 189 respectively. Cooperating with the disks 188 and 189 is a double feeding pawl 190 having two operating extremities 191 and 192, and pivoted mid-way of its length at 193 to a yoke 194. At its upper end the yoke 194 is pivoted to a hanger 195 pivoted to the main frame of the machine. At its lower end the yoke 194 is pivoted to a hanger 196 rigidly mounted on a short shaft 197 which extends through the side frame and has mounted on its inner end an arm 198. Pivotally connected to the arm 198 is a link 199 which may be operated by any suitable mechanism preferably a cam (not shown) so as to give a slight oscillation to the shaft 197 at each operation of the machine. Considering the ribbon to be wound about the spool 172 and the feeding movement of the ribbon being in a downward direction to be wound on the spool 171, the operating parts of the feeding mechanism would be in a position shown in Fig. 7. In'this position the feeding extremity 191 of the pawl 190 is in engagement with the feeding disk 188 of the spool 171. It will thus be seen that when an oscillatory movement is given to the shaft 197, the hangers 195 and 196 will move downward thereby carrying the yoke 194 downwardly to cause the pawl 190 to move the notched disk 188 a distance of one tooth, thereby advancing the inking ribbon.
The operating movement of the hangers 195 and 196 is first to carry the yoke 194 downwardly and then upward to an extent double the distance of downward movement and then to be given a second downward movement to carry the hangers 198 and 194 back to normal position. It will thus be seen that both the extremities 191 and 192 will be given an operative movement relative to their appropriate disks 188 and 189, but with the parts in the position shown in Fig. 7, the extremity 191 is the only one of the two extremities which is in operative engagement with its appropriate disk. Therefore the feeding movement of the inking ribbon will be in one direction only.
Nearits two extremities the pawl 190 carries a pair of pins 200 and 201 cooperating with a pair of pawls 202 and 208 respectlvely. The pawls 202 and 203 are pivotally mounted on the pivotal connections beneath the yoke 194 and the hangers 195 and 196 respectively. As shown in Fig. 7, a
spring 204 normally tends to rock the pawl 203 about its pivot in a counter clockwise directlon. On the other end of the pawl 203 opposite to that to which the spring 204 1s connected, there is formed a bifurcation 205, one of'the adjacent fingers 206 having a bevel face resting against the pin 201 when the parts are in a position shown in F 1g. 7. When the pawl 203 is in this position, the operating pawl 190 will be held n the position shown in Fig. 7 to cause the ribbon 170 to be wound on the spool I When the extremity 191 of the pawl 190 is in a position shown in Fig. 7, the pin 200 Wlll be in the notch of the bifurcation 207 formed in the drawn by spring 208 which tends to move the pawl 202 about its pivot in a clockwise directlon. By reason of the engagement of the notch 207 with the pin 200, and the bevel face of finger 206 of pawl 203 with the p1n 201, the pawl 190 will be held in a position shown in the figure.
Ad acent the spools 171 and 172 are pivoted a pair of bell cranks 209 and 210 respectively. The springs 204 and 208 are connected to the bell cranks 209 and 210 respectively and tend to turn the bell crank 209 about its pivot in a counter clockwise direction, while turning the bell crank 210 about its pivot in a counter clockwise direction. Each of the pawls 209 has a projection 211 which bears upon the roll of ribbon which is wound upon its appropriate spool. It will readily be seen by reference to Fig. 7, that when the bulk of the ribbon is wound on the spool 171, the bell crank 209 will be rocked about its pivot so as to bring the arm 212 thereof beneath the right hand extremity of the pawl 202. When the bell crank 209 is so rocked, the succeeding operation of the machine will cause the right hand end of the pawl 202 to strike the upper end of the arm 212 and upon a continued upward movement of the yoke 194, the pawl 202 will be rocked about its pivot and by reason of the formation of the slot of the bifurcation 207, the pin 200 will be forced to the left thereby rocking the double pawl 190 about its pivot 193, thereby to disengage the extremity 191 from the notched disk 188 and to engage the extremity 192 with the notched disk 189. It will therefore be seen that when pawl 202 which is spring such an operation takes place, the subsequent manner just described, the pin 201 carried thereby will enter the notch of the bifurca-' tion of the machine to defeat the purposes thereof, suitable locking mechanism is pro-' vided for preventing an operation of any of the amount levers 26 until the totalizer setting lever 57 is moved to bring one of the, to-
' talizers into operative position. By referonce to Fig. l'it will be seen that while only four totalizers are provided, the lever 57 has five positions of adjustment. The position in which it is shown in Fig. 1 is the home position and any operation of the machine, while the lever is .in that position, to register an amount, is prevented by reason of an interlock provided to prevent an operation of amount lever until the special lever '57 is moved to another one of its positions of adjustment. 4
This interlocking mechanlsm comprlses the following mechanism. The lever 57 (see Fig. 1) is provided with a cam groove 213 into which projects an anti-friction roller 21 1 carried by an arm 215 rigidly mounted on a rock shaft 216.. ;A djacen t each of the amountlevers 20 (see Fig. 3) is an arm 217' rigidly mounted on the shaft 216 and having a locking nose 218 projecting into a notch 219 formed in a locking plate 220 carried by the part 21 of the-amount lever. When th e lever 57 is in the position shown in Fig. 1, the formation of the cam groove 213 will cause all of the levers 217 to be held in a position wherein their noses 218 are held in lock-" ing engagement with the locking plates 220. As soon however, as the lever 57 is moved downward to any other of its possible positions of adjustment, the cam roove 213 will effect the rocking of the sha t 216, throughthe medium of the anti-friction roller 214 and the arm 215. The rocking movement of the shaft 216 will thus effect a disengagement of all of the locking noses 218 fromthe locking notches 219 formed in the plates 220. It will thus be seen that the levers 20 are locked against operation until the lever 57 is so moved.
The mechanism just described will also act to prevent the movement of the let er 57 back to the normal position in which it is shown in Fig. 1, while an amount lever 20 is out of normal zero position. The plates 220 are formed with an upper curved surface formed on an arc concentric with the pivotal point 22 of the amount levers 20. It will readily be seen that Whenthe lever 57 is moved to unlock the amount levers and an amount lever is then moved to one'of its positions of adjustment, the notch 209 appropriate to the moved lever will pass from beneath its appropriate locking nose 218 and the continued curved surface of the plate 220 will pass beneath the locking nose.- This prevent 'a further rocking movement of the shaft 216, as the nose' 218 will then bear on the surface of the plate 220. Consequently, by reason of the formation of the cam groove which would. tend to rock the shaft 216 a restoration of the lever 57 to normal positlon, while one of the amount levers is out of normal position, is absolutely prevented.
Machine Z0ck.-Means are provided,"un-' der control ofthe totalizersetting lever 57 for locking the machine at the end of each operation of the machine and holding the same locked until the lever 57 has been given a movement to position a desired. totalizer for operation. The locking means just referred to is clearly shown in Fig; 12. As hereinbefore' described, the crank handle 215 is adapted to be given two turns at each operatlon'of the machine and through the medium of the train of gears shown in said figure the shafts 16 and 17 are adapted each to be given a singlerevolution at every operation of the machine. The gear shown in Fig. 12 which is fast on the shaft 16 carries a locking plate 221 formed with-a locking notch 222. Pivoted adjacent the locking plate 221 is a locking pawl 223 normally sprlng drawn out of engagement with said locking plate, The pawl 223 is formed with a lockln'g nose 224 which is adapted to engage in the locking notch 222 at the end of each operation of the machine. This locklng engagement is effected by the engagement of a pin 225 with an upwardly extending arm 226 formed on the pawl 223.- When the pawl 223 is moved to the position shown in Fig. 12, it is held in that position against the action of the spring 227' by a spring pressed plunger 228 carried in the down wardly extendin arm 229 rigidly mounted on the rock sha t 8 1. As hereinbefore described, the shaft 84 carries the arm 83 (Fig. 1) to which is pivotally connected the rear end of the link 77 controlled by the lever 57. It will thus be seen that whenever the lever 57 is moved to one of its positions of adjustment, the shaft 84 will be rocked through the medium of the link 77 as hereinbefore described, thereby moving. the plunger 228 out of holding engagement with the pawl 223, thereby to permit the pawl 223 to move downward under the action of the spring 227 to. disengage the nose 224 from the locking notch 222, thus permitting anoperation of the machine. When the ma chineis then operated the gear on the shaft 16 will be rotated clockwise and upon the completion of a single rotation of said shaftthe pin 225-carried by said gear will engage the arm 226 to again rock the locking pawl 223' to locking position, in which position it will again e held by the spring pressed plunger 228. I v
General operati0n.-The general operation of the machine described herein is as follows: It is customary in aymachine of this type to assign each of the plurality of totallzers to some particular class of transactions or' to assign each-totahzer tosome part1cular grasp the lever 57 and rock the bell crank 71 to release the temporary latchingmeans of the setting lever 57. The lever 57 is then moved downwardly until the desired totalizer is placed in cotiperative relation with held in both normal zero position and any the registering racks 35. The handle 57 and bell crank 71 are then released and the temporary latch will again be effective to latch the lever 57 in its adjusted position. While the bell crank 71 is rocked and the lever 57 is intermediate any of its positions of ad-- justment, it will be remembered that the latching lug '79 on the link 77 will thenbe effective to prevent any rotation of the shaft 16, and, consequently, any operation. of the machine until the lever 57. has been moved to one of its adjusted positions, is thereby prevented. It-will also be remembered that the adjustment of the setting lever 57. will act to release the machine lock. mechanism shown in Fig. 12. If a No Sale transaction is to be recorded and merely identified with some clerk or department, the machine is then free to be operated and an indication of the clerks initial or department will be displayed without, however, any amount appearing; on (the amount indicators. If an amount is tobelentered, however, the amount levers 20 are first adjusted to a position rep-- resenting the amount .to be recorded. When the lever 57 was moved out of its normal non-registering position the interlocking mechanism comprising the cam slot 213, roller 214C, arm'215, shaft 216 and arms 217 was operated to release the amount levers to permit an operation thereof. The levers are latching means comprising-the locking lug 28 carried on the outer end 24 of the amount levers. 'If it is desired to register an amount, the temporary latch is first released by pushing in the outer end of the amount levers and then moving the same down along a scale, which may be formed on-the outer front portion of the. casing, until the lever is in a position representing the amount to be recorded. The handle 26 is then released and the amount lever will be held in its adjusted position. Assoon as the lever 20 is moved out of normal zero position it will result in the displacement of the pawl 51 from normal position to place the same under control of the restoring disk 55 carried by the rotation shaft 17. After the amount levers have been properly adjusted the machine is then ready to be operated by two turns -of the operating handle 15 shown'in Fig. 12. As soon as the turning of the op- 'erating handle is begun the totalizer frame 34 will be elevated to cause the pinions 36 of the positioned totalizer to mesh with the racks 35 formed on the amount levers. disks 5.5 will then become effective to restore all of: the amountlevers 20 which had previously been adjusted, and upon the restoration of the amount levers the amount, represented' by, the adjustment which had been preliminarilygivento them, wi-ll be added on the positioned totalizer. Upon the comletion .of the restoring movement the rame 3.41 will again be lowered to disengage the positioned totalizer from the operating racks 35 and the transfer mechanism will thenbecome efiective to effect any transfer which has been, placed in operative condi- 'tion during the adding of the amount'to any total which may previously have been represented by the position of the totalizer elements.
The
Just previous to the beginning of the restoring movement of the amount levers, mechanism will become effective to posit on both the printing and indicating mechanisms. The positlon which will be assumed by the indicators 130 and the printing segments is predetermined by the adjustment store the rollers 138 carried by the beams 136 midway of their length, back to normal neutral position'in alinement with the pivotal point 22 of the amount levers. This restoration of'the roller 138 to normal neutral position will effect the movement of the pivotal points 137-corresponding in extent to the preliminary movement given to the pivotal points 137. This movement will then be transmitted to the indicators and printing segments'through the medium of the links 134 and segments132 and through the arms 184:, shafts 185, links 187 and segments 160. This positioning of the indicator and printing mechanism.will be effected during the time that the positioned totalizer is being carried by e amount levers. As soon as the positioning of theindicators and printing mechanism has been effected the amount levers are then released and are free to be restored to normal zero position, as hereinbefore stated. During the restoring movement it will, of course, be remembered that the indicators and printing segments are allowed to remain in their adjusted positions and during such time the printing mechanism is operated to cause the platen 173 to take an impression from the type wheels 164 of the detail record strip 165 through an ink ribbon 170.
The feeding mechanism in connection with the detail strip will be effected during the reciprocating movement of the platen 17 3 and platen arm 174 through the medium of the link 183, plate 180, feeding pawl 181 and the notched feeding disk 179 hereinbefore described. Simultaneously with the feeding of the detail strip, the mechanism for advancing the inking ribbon will also become effective.
While the form of mechanism herein shown and described is admirably adapted to fulfil the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown and described, as it is susceptible of embodiment in various forms, all coming within the scope of the claims which follow.
