rlhis invention relates to improvements in registers and like machines, and is more particularly directed to controlling means for such machines. v
For illustrative purposes, the inventionis shown applied to a machine of the type d1sclosed in Letters Patent of the United Stat-es, No. 1.242,170, granted October 9, 1917, toy F. L. Fuller, and No. 1,619,796, granted March l, i927, to B. M. Shipley.
Specifically, this invention is an improve ment on the mechanism disclosed in Letters Patent ot the United States, Number 1,736,063?, granted November 19, 1929, to Samuel Brand. Y f 'lhe'patents mentioned above disclose a register or accounting machine of the key-set type efpiipped with thewell known total con trol lever to condition the machine to make add, sub-total, and total7 operations. This control lever, as disclosed in said patents, is manually set before the machine is released for operation and, after the completion oi the operation, is manually restored to its normal add position.
The Brand a iplication discloses means to automatically restore the control lever to its normal or cadd position immediately at the end ot a total operation, which relieves the operator ot this duty. Brands mechanisni,A however, restores the control lever to add position at the completion'of each total taking' operation whether it is desired to do so or not, and the condition frequently arises when the operator desires to make a series of total operations to successively clear the several totalizers with which machinrs of the type indicated are usually provir l. selective automatic restoration of the total control lever to its add7 position.
lt is, therefore, an object of the present invention to provide a register or accounting machire ot the type indicated, with novel mecha.` in under control of the operator to determine the effectiveness of the automatic restoring means.
Another object is to provide a' machin-e of the type indicated with a key-controlled 1929. Serial No. 362,962.

ith these and incidental objects in view, the invention consists of certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims anda preferred form or embodiment ot whichk is hereinafter described with reference to the drawings which accompany and form a part of this speciiication.

General description to select the totalizers and otherwise control the operation of the machine, indicators to indicate the amount and classification of the transaction registered in the machine, and a total control lever to position the machine to make adding, sub-totaling7 or totaL ing operations. Several other elements are' included in the general make-up of the niach1ne,such as printing mechanism, special counters, etc., but since this invention is d1- rected more particularly to automatic restoring means for the total control lever, and mechanism for controlling the restoring means, description and illustration of all elements not pertinent thereto are omitted from this application.
In registers and accounting machines, such as are disclosed in the above-referred to patents, the amounts of the items or transactions entered into the machine are accumulated on one or more of the totalizers selected under the control of clerks or transaction keys, and the conditioning or total control lever. After a lapse of time, as for instance, at the end ot each day, it is desired to take a total from certain of the totalizers. rlhese totalizers, in the particular type of machine chosen for illustrative purposes, are arranged in a plurality of groups, and the particular group from which it is desired to select a particular totalizer to be cleared, is selected by manually moving the total control lever from its normal add position to a certain one of its several remaining positions, after which the appropriate transaction key is depressed which sets mechanism to select a desired totalizer. The machine is then operated to select the desired totalizer and to take the total therefrom. After the operation of the machine, the total control lever, as disclosed in the above-mentioned patents, may be manually returned to its adding position, or adjusted to another of its totalizing positions, or allowed to remain in its last position, depending upon the nature of the next succeeding operation, and the group from which it is desired to select a particular totalizer for the operation.
The Brand patent, referred to above, discloses mechanism which, upon adjustment of the total lever to a certain one of its tota-liZing positions, and operation of the machine, automatically returns the lever to its adding position at or near the end of the machine operation, regardless of the particular totalizer selected.
In the normal use of the machine, it is desired, at the end of ay days business, to clear all of the totali/Gers which have been selected during that day, under the control of the banks of totalizer-selecting keys. In such cases, it is not desired that the total control lever return automatically to its add position after each totalizer is cleared, as to do so would only necessitate repositioning the lever to the desired totalizing position before the ne: 3ii=.\2eed.iiig operation. For this reason mechanism is novv provided to render ineffective the automatic restoring mechanism for the tot-al lever at such times as the operator desires to make successive totaling operations.
However, this type of register is usually constructed ith a certain special key in the totalizer selecting bank which the operator depresses Whenever it is desired to list a plurality of items, the total of which is desired immediately. This key is known as the list key and is usually located in the l position in the key bank. After the amounts of a group of items have been accumulated on the totalizer selected under control of the list key, the total control lever is adjusted to the correct position for conditioning the machine to take the total of the list totalizer. Since this is the only totalizing operation to be made at this time, it is desirable to have the automatic total lever restoring means effective to return the total lever to its add position.
Mechanism for selectively controlling the effectiveness of the automatic restoring mechanism for the total control lever constitutes the subject matter of lthe present invention and is fully described below.
Detail description The total control lever 30 (Fig. 2) which conditions the machine for item entering and total taking operations, projects from a substantially circular control disk 3l, pivoted on a stud 32, suitably supported in the machine. The total control lever 30-31 is shown in full lines in its add position, the dot-and-dash line in Fig. 2 indicating the first position of the lever below its add7 position, to which it is adjusted When printing the total ofthe amounts accumulated by lis ,Y ing operations. The various mechanisms adjusted by movement of the total control lever 30 to its total7 position for conditioning the machine to make a totalizing operation, are only partially disclosed herein .and for a full and complete understanding thereof, reference may be had to the above-mentioned patents.
The usual drive shaft 33 is journaled in a right side frame 34 (Fig. l) and left side frame 35 (Fig. 3) of the machine. This shaft makes one rotation in a clockwise direction, as viewed in Figures 1 and 3, at cach :uiding operation of the machine, and two rotations in the same direction, at each totaltaking operation, for reason ivell known in the art, and which are fully set forth in the abovementioned patents. Any suitable means mav be employed to rotate the shaft 33, the usual means being an electric motor. However. in case of failure of the electric current a crank 36 indicated by dot-and-dash lines in Fig. 1, enables the machine to be manually operated. The crank 36 is removably coupled rto pinion 37 ournaled on a stud 3S projecting from the right side frame 34 of the machine. The pinion 3T meshes with a large gear 39 journaled on a stud 40 also projecting from the right side frame 34, the gear 39, in turn, meshing with a gear 41 fast on the drive shaft 33. The ratio of the gears 37, 39 and 41, is such that it requires two complete rotations, in clockwise direction, of the crank 36 to impart one complete rotation in Clockwise direction to the gear l1 and the drive shaft 33. The gear 39, however, completes only one-half of a rotation in counter-clockwise direction at each adding operation of the machine, and one full turn in counter-clockwise direction at each total-taking operation of the machine.
Adjustment of the total control lever 30 in either direction from its normal or add position with a consequent rocking of the disk 31, causes the walls of a cam slot formed in the total control disk to shift a pin 106 carried by one arm of a multiple-armed lever 107 pivoted at 109, to rock the lever. An arm 112 also pivoted at 109 and having a pin and slot connection 111 with the multiple-armed lever 107, has a cam-shaped slot 115 formed therein to accommodate a pin 116 on an arm 117 fast on a suitably supported shaft 100. A spring 1141 extending between the multiplearmed lever 107 and the cam-slotted arm 112 normally holds these parts separated as far as the pin and slot connection 111 will permit.
A link 97 (Fig. 1) connects an arm 99 fast on the outer end of the shaft 100 with one arm of a lever 89 pivoted intermediate its ends at 90, the remaining arm of the lever 89 having a pin and slot connection with one end ot a pitman slidably mounted on the stud 40 on which the large driving` gear 39 turns. The pitman 120 determines whether or not the machine will make one or two cycles of operation.
A disk 118 journaled on the stud 40 just behind the pitman 120 remains stationary during operations wherein the drive shaft 33 is to make but a single rotation, due to the disk 118 being held to the pitman 120 by a stud 119 on the pitman resting in a recess in a cani slot 121 formed in the outer face of the disk 118. y
A radially extending coupling slide 124C` slotted to embrace the stud 40 lies in a diametrically extending groove 127 formed across the back of the normally idle cam di sk- 118 and between the cam disk and the large drive gear 39, such coupling slide carrying a laterally projecting ear 123 at its outer end embraced between a pair of inwardly projecting studs 122 extending from the inner face of the pitman 120, thek outer end ofthe coupling slide lying in line with a recess formed in the large gear 39 when the machine is at rest.'
So long as thetotal control lever 30-31 remains in its normal or add7 position, the linkage commencing with the multiple-armed lever 107 (Fig. 2) and terminating with the lever 89 (Fig. 1) maintains the pitman 120 and the coupling slide 124 in their normal idle positions, but adjustment of the total control lever 30-31 in either direction, as, for instance, to the first rposition below the add position, shown in dot-and-dash lines in Fig. 2, operates through the linkage to rock the lever 89 clockwise, to draw the pitman 120 and hence the coupling slide 124 outwardly radially of .the cam disk 118 and large gear 39, to enter the projection 119 of the pitman into the cam groove 121 on the face of the disk 118 and simultaneously enter the outer end of the coupling slide 124i into that one of the recesses 125 which, at that time, lies in line therewith.
The extent of movement imparted to the pitman 120 by the total control lever'30, 31 when adjusted is always the same, due to the cam slot 110 (Fig. 2) in the total control disk 31, irrespective of the extent of adjust'- ment of the total control lever, and is just sufficient to effect the coupling of the cam disk 118 to the large drive gear 39, but as the cam disk 118 completes the first half of its rotation, the cam groove 121 yor the disk shifts the pitman 120 farther outward radially, the pitman being held at its outward limit of travel through nearly the remaining half of the rotation of the cam disk, after which it is returned to its intermediate position where it remains until the end or the rotation of the cam disk.
The pitman 120 carries a stud 126, and as it is shifted by the cam disk 118'to its extreme outer position, the pitman through the stud 126, shifts mechanism not pertinent to the present invention and hence not shown, which controls the application of ypower to the large drive gear 39 so as to disable the usual control mechanism until the large gear is given a single complete rotation. Return of the pitman 120 to such. intermediate position restores the rotation controlling mechanism (not shown) to position where it will become effective atthe end of the complete rotation of the large gear 39.
The coupling slide 124, however, does not partake of the additional outward and inward travel of the pitman 120 under control of the cam disk 118, because rotating or the large drive gear 39 carries the ear 123 from between the pins 122 of the pitman 120 which is returned to its intermediate position in plenty of time'to enable the ear to insert itself between the pins as the ear completes one counter-clockwise rotation.
Automatic rcstomt/oa of the total control Zever to normal 'position As originally designed, the total control lever 30, 31 was manually adjusted to any of' its positions and remained where set until manually shifted to another position, but the United States Letters Patent of Samuel Brand, No. 1,736,067, disclosed means to automatically restore the total control lever 30, 31 to its normal or add position, from its first position below add back to its add or normal position.
Movement of the total control lever 30r` from its add position to its first position below the add position, as shown in dotand-dash lines in Fig. 2, shifts a lug 42 projecting rearwardly from the control plate or disk 3l, into the path of oppositely placed rollers 43 and 44, rotatively mounted within an angulaigroove 45 (Fig. 5) formed in the periphery ot' a restoring collar 46 journaled on a shaft 47 supported in the side frames 34 and 35.
A segmental gear fast on a short shaft 5G j ournaled in a bracket 57 (Fig. 1) entending downwardly from a back frame 58 secured to the machine side trames 34 and 35, meshes with a partial gear 59 (Figs. 2, 4 and loosely mounted on the shaft 47 adjacent the restoring collar 46. A strong spring 60 (Fig. 1) attached to an arm 6l secured to the other end ot the short shaft 56, constantly urges the shaft and the toothed segment 55 in clockwise direction to the position shown in Figs 2 and 4, in which the parts are arrested by contact of the laterally turned end ot' the arm G1 (Fig. l) with the back plate 58. ik spring 62, (Fig. 5) coiled about the l shaft 47, constantly presses the partial gear 59 axially against the adjacent end ot' the collar 46, to normally maintain the driving lugs G3 projecting from the hub of the partial gear 59 within not-ches (i4 in the adjacent edge of the restoring collar 46.
A hooked tensioning link 82 (Fig. 1) pivotally connected to the arm G1, depends to a point adjacent a stud 81 mounted on a lever 72 pivoted at 'T3 to the side frame 34, and
" when the machine is operated, under certain adjustments, this stud is adapted to engage the hook 8B to pull the tensioning link 82 downwardly and rock the arm (51, shaft 56 and toothed segment 55 to rotate the partial gear 59 and tension the spring 60.
A cam turning *ith the drive shaft 33, is adapted, in its rotation, to wipe against a roller 71 on the lever 7 2' at each operation of the machine, to rock the latter in clockwise direction against the tension of a strong return spring` 7 4 which maintains the roller 7l in Contact with the cani 70 at all times.
The nodal point of the cain normally lies just beyond the roller .7 1, and as the shaft 33 makes a single complete rotation at each adding operation, and two rotations at each totaling and sub-totaling operation, the cam 'TO will rock the lever 72 with its stud 8l clockwise near the end of each rotation and the spring 7 4 will restore the lever in counter-clockwise direction to normal just as or immediately after the shaft completes its rotation.
But the hook 83, although embraced between the tree end of the lever 72 and a guide arm 80, normally lies outside the path ot travel of the stud 81 so long as the total control lever 30, 31 occupies its normal add position, being held in such idle position b v a restraining link 85 slidably supported on a guide stud 86 intermediate its ends, one end ot the restraining link 85 having an open latch 84 releasably hooked over a. pin 91 on the tensioning link 82, and the opposite end of the restraining link 85 having an inclined slot to encircle a stud 8T carried on one arm of the lever' 89 constituting part of the linkage between the total control lever 30, 31 and the pitman 120.
A spring 92 tends to draw the restraining link 85 to the left (Fig. 1), but so long as the total control lever 30, 31 remains in its add position, it will retain the lever 89 in the posit-ion shown in Fig. 1, which lastnamed lever will maintain the restraining link 85 at the right hand limit of its travel to hold the hooked link 82 in idle position disconnected from the rocking drive lever 72.
The total control lever 30, 31, is adjustedprior to the operation of the machine and when set to its first position below its add position, operates the linkage previously described, terminating in the lever 89 to rock the latter clockwise and cause the pitman 120 to shift the coupling slide 124 to effective position.
The stud 87 carried by the lever 89 rocks to the left to enable the spring 92 to draw the restraining link 85 to the left (Fig. 1), and with it, the hooked link 82.
The advance of the hooked link 82 is not sufficient at this time, to locate the hook 83 beneath the stud 8l towards which it advances.
The machine being now set for a total taking operation, the crank 3G is operated to turn the pinion 37, the large gear 39 and the gear 41 on the drive shaft 33, and due to the coupling slide 124, the large gear 39 carries the cam disk 118 along with it, the projection 119 of the pitman 120 lying in the cam groove 121 of the cam disk.
It will be remembered that the large gear 89 and its cain disk 118 make one complete rotation on total taking operations and as a consequence the drive gear 41 and the drive shaft 33 with its cam 70 make two complete rotations.
The cam 70, shortly after the beginning of its first rotation, starts to depress the drive lever 7 2, but since the restraining link 85, at this time, still holds the hook 83 apart from the stud .81 on the lever 72, the lever moves idly downward, and at the end of the first rotation the tensioned spring 74 snaps the lever back to its normal position as the high point of the cam 70 escapes the roller 71 on the lever.
However', justprior to the return of the Gli clockwise travel to the lever 89 which enables the spring 92, operating upon the restraining link 85, to draw the hooked link 82 into the path of the stud 81 on the drive lever 72 which, at this time, islocated some distance beneath the hook 83. n
Consequently, the lever 72, as it returns to its normal position under the influence of the spring 74 at the end oit the first rotation of the cam 70, causes the stud 81 to strike the inclined face `93 and rock the hooked link countereclockwise against the tension of the spring 92 which immediately restores the hooked link to its adjusted position with its hook 83 beneath the stud 81 as soon as the stud passes the hook. The slot and pin connection 87 between the restraining linkrv 85 and the lever 89 permits relative motion between the link and lever tor this purpose.
The cam groove 121 continuing to hold the pitman 120 at its limit of outward travel, the cam 70 on the drive shaft 33, as it starts on its second cycle of rotation, depresses the drive lever 72 and its stud 81, which latter contacts the hook 83, drawing the link 82 downwardly to rock the arm 61, shaft 56 and toothed segment counter-clockwise. The toothed segment, being meshed with the partial gear `59, turns the latter clockwise. The teeth 63 (Fig. on the hub of the partial gear, due to their pitch, ratchet idly over the co-acting recesses 64 on the hub of the total lever` restoring collar 46 during the clockwise rotation of the partial A dog 65 pivoted at 66 on the side 'frame 34, holds the restoring collar 46 against` clockwise rotation at this time, which might be induced by the kfriction between the hub ot the partial gear and the collar due to the pressure of the spring 62 encircling shatt- 56, a springk67 holding the nose of the dog in engagement with one of the notches 69 in the hub of the restoring disk.
The toothed segment 55 carries 'a stud 95, which contacts the tail 96 of the dog 65 just as the toothed segment completes its counterclockwise travel, to disengage the nose ot the deg from the notch 69 to free the restoring collar 46 for operation.
Meanwhile, as the drive lever 72 rocks clockwise under the infiuence of the cam 70 on the drive shaft 33, to .draw the hooked tensioning link 82 downwardly and tension the drive spring 60, the pin 91 of the tensioning vlink 82 is withdrawn from the throat of the latch 84 which is cut away or beveled oft', as at 94 for clearance and to form a guiding sartace for the pin 91 as hereinafter appears.
4s the large drive gear 39 and the cam disk i158 approach the end oi' the secondcycle o? rotation in a totalizing operation, the cam ve 121 shifts the pitman 120 inwardly to termediate position, as a result of which, the pitman rocks the lever 89 counter-clockwise to its intermediate position. On this partial return movement, the stud 87 partially returns the restraining link 85 towards its normal position, but since, at this time,
theL lever 72 has drawn ythe tensioning link 0 82 and its rpin 91 downwardly so that the latter lies opposite the clearance iace 94 of the restraining link, this link exercises no influence upon the tensioning link which remains hooked under the stud 81 of the drive lever 72,
until the spring 74 restores the lever 72 to s The drive spring 60, in drawing the teni sioninglink 82 upwardly, rocks the arm 61, shaft 56 and toothed segment 55 in clockwise direction to turn the partial gear 59 counter-clockwise, whereupon the abruptvr side-s of that tooth 63 on the hub of the partial gear which is entered in the notch 64 of the restoring collar 46, turns such collar counter-clockwise and with it the rollers 44 piounted in the peripheral groove of the col- As previously explainech'the manual adjustment ofthe total control lever 30, 31 from its add position to its first total taking position below the add position turns the total control plate 31 to introduce the peripheral lug 42 thereof into the peripheral groove 45 of the restoring collar 46.
Hence the collar, on its counter-clockwise rotation, brings one of the rolls 43,44 into contact with the lug 42 to restore it, together with the total control disk 31, and its control lever 30 to the normal or add position. Y
The faced end of the arm 61 striking the 'inner side of the back traine 58, arrests the farther travel in clockwise direction of the toothed segment 55, which latter, as it returns to normal position, withdraws the stud from the tail of the dog 65 to release the dog to the action of its spring 67 which rocks the nose of the dog into Contact with the hub of the collar so that inthe rotation of the collar, as soon as a notch 69 is brought beneath the nose, the dog will drop in to lock the collar against clockwise rotation on the next operation of the machine.
`The total control lever 30, 31 on its automatic return to its normal .add position, causes the wall of its cam slot 110 (Fig. 2) to operate the linkage controlled therebyincluding the lever 89, to which is imparted its final step of counter-clockwise travel, the lever, in turn, restoring the itman 120 to its normal posit-ion with its pin 119 in the seat in the inner wall of the cam groove 121. The
pitman, on it-s restoration, disengages the coupling slide 124 from the large gear 39 and sets the mechanism (not shown) which prevents further operation of the machine.
If, prior to the operation of the machine, the total control lever 8C', 81 is moved to any other position except-ing' the first position be low the add position, the restoring mechanism will operatD idly since the lug 42 is not in the path of the roller 43. Thus, the tot-al lever will only be returned to its home position from the first position below the add position.
rIhe bank of transaction keys and the differential mechanism controlled thereby are old in the U. S. Letters Patent to Fuller, No. 1,242,170, and to Shipley, No. 1,619,796, heretofore mentioned, to which reference may be had for a full and complete disclosure of this mechanism. However, for a complete understandinOf of the present invention, a brief description of the key bank and differential controlled thereby follows.
The transaction keys (Fig. 3) are slidably mounted in the usual key frame 146 supported in the machine on cross rods 147 and 148 extending between the machine side frames 34 and 35. A detent bar 149, suitably mounted in the key frame 146 cooperates with key pins on the keys 145 to retain the keys in their depressed positions. When, towards the end of the operation of the machine, the depressed key is released by mechanism (not shown herein) the key depressed is restored to its outward position.
Operation of the main drive shaft 33 in clockwise direction rotates a pair of cams 162, 168 fast thereon. These cams rock a bell crank 164 journaled at 165 on a hanger of a pair of hangers fixed in the machine, to rock the bell crank first clockwise and then counter-clockwise. A link 166 connects the bell crank with a shouldered driving sector or actuator 161 journaled on a stud 154 extending between the hangers 155, one only of which is shown, so that the drivingr sector is rocked through a constant path of travel first clockwise and then counter-clockwise at each operation of the machine.
A differentially adjustable arm 158 journaled on the stud 154 is slotted at its outer end to accommodate a stud 156 projecting from one arm of an elbow lever 157 pivoted at 144 to the outer end of a second differentially adjustable arm also journaled on the stud 156 parallel with the arm 153 and this elbow lever 157, together with a. link 158 mounted on the arm 160, unite in supporting a latch 159 which normally connects the differentially movable arms 153 and 160 with the invariably movable actuator 161.
The differentially adjustable arms 153, 160 normally lie at their extremes of counterclockwise travel, the latch 159 connecting them with the actuator, and a spring-pressed zero stop pawl 150 fast on a short shaft 151 journaled in a depending ear of the key frame 146, normally lies in the path of the free end of the differentially movable arm.
Depression of any one of the keys 145 rocks the zero stop pawl 150 to its ineective position out of the path of the differential arm 153. Depression of any one of the keys 145 interposes its inner end in the path of thc elbow lever 157. The actuator 161, because of its latch connection 159 with the differential arms 153, 160 carries the differentially movable arms therewith on its clockwise travel until the forward end of the elbow lever 157 strikes the inner end of the depressed key, whereupon continued movement of the actuator rocks the elbow lever 157 counter-clockwise to draw the latch 159 out of cooperative relation with the actuator 161 and thrusts the nose of the latch into one of a succession of notches 167 in a serrated plate 168 secured to the inner face of the key frame adjacent the inner ends of the keys. The actuator 161 completes its invariable excursion and on its counter-clockwise return movement, as the shoulder in the actuator 161 arrives opposite the foot of the latch 159, a spring 169 draws the latch out of the notch 167 and engages the righthand end thereof with the shoulder on the actuator 161 to disconnect the latch from the keyboard. At the same time, a face 170 of the actuator 161 engages a stud 171 projecting from the differentially movable arm 160 and restores the arms 153, 160 to their normal positions as viewed in Fig. 3. The differentially movable arm 160 variously positions the left-hand end of a beam pivotal1y connected thereto, and having its right hand end bifurcated to straddle a stud 181 in a link 182. The lower end of the link is pivotally connected to a type carrier adjusting arm 183 journaled on a shaft 184 turning in bearings in the side frames 34 and 35, and the upper end of the link is pivotally connected to an aligner segment 185 fast on the shaft 186. The differential movement of the differentially movable arm 160 under the control of the transaction keys 145 differentially adjusts the left hand end of the beam 180 accordingly. On
the clockwise travel of the bell crank 164, a roller 186 thereon contacts the lower edge of the beam 180` to complete the adjustment thereof if necessary. The differential movement of the beam 180 is transmitted by the link 182 to the arm 183, to set mechanism in the printer (not shown) but which is disclosed in the above-mentioned patent, and to set the indicator aligning segment 185 to a position corresponding to the particular key l:
depressed. This segment 185 is provided with teeth 190, the purpose of which is to set indicators, (not shown herein) but which are fully disclosed in the above-mentioned patent.
An aligner bar 191 supported on a plurality of arms 192, only one of which appears in the drawings, which are fast on an aligner shaft 193 journaled in the frames 311-35, cooperates with serrations on the aligner' segment 185 to align the segment 185, link 182 and the arm 183 in the positions to which they are adjusted. Any suitable mechanism may be employed to operate the aligner shaft 193.
ln the machine as disclosed in the U. S. patent of Samuel Brand, Number 1,736,067, the total lever restoring mechanism functions to restore the total control lever to its normal position from its lirst position below the add position at the end of each totalizing operation, regardless of which of the transaction keys are depressed. However, as heretofore explained, it is desirable to disable the total control lever restoring device when resetting certain of the totalizers to zero, and to this end, mechanism now to be described, is adjusted under the control of certain, at least, of the bank of transaction keys (Fig. 3), to disable the total control lever restoring mechanism when the machine is operated with such transaction keys depressed.
This disabling mechanism may conveniently comprise a bolt 130 (Fig. 1) slidably mounted on guide studs 131 and 132 projecting from the right side frame 34 of the machine. A stud 133 near the upper' end of the link 130 projects through an aperture 134. in the right side frame 311 to cooperate with a lin ger 135 fast on the shaft 136 which is differentially rotated under the control of the transaction keys. The ends of the shaft 136 are tapped out and journaled on trunnion studs 137, the heads 138 (Fig. 1) of which are secured to the side frames 34 and 35,. Only one of the trunnion studs 137 appears in the drawings, the other being on the opposite side of the frame (F ig. 3). The shaft 136, linger 135 and bolt 130 are shown in Fig. 1 with the differential inechaiiismiii the zero position. Upon an operation of the machine, the differential mechanism, under control of the 1 key, rocks the linger 135 one step in clockwise direction to lower the bolt 130. This movement, however, is not sulficient to enter a lug 139 formed on the lower end of the bolt 130 into a recess in the upper edge of the link 85. However, when the differential mechanism is operated under the control of the transaction keys in the 2 to 9 positions inclusive, the finger 135 rocks a corresponding number of steps farther in clockwise direction to permit the spring 129 to lower the bolt 130 a greater extent, to enter the lug 139 in the recess 1110 in the restraining link 85. The bolt 130 needs to operate but two steps before its lug 139 seats itself in the recess 140, after which the linger 135 merely rocks idly in clockwise direction away frointhe stud 133 when transaction keys in the 3 to 9 positions, inclusive, have been depressed. Under such adjustment of the transaction keys, it is seen that, when the total control lever 30 is shifted from its add to its first totalizing position below the add7 position, to rock the lever 89 (Fig. 1) through y.
its initial movement or step in clockwise direction, the spring 92 causes the restraining link 85 to follow until the right hand wall of the recess 140 in the link contacts the lug 139 on the lower end of the bolt 130, which arrests the restraining link 85 while the latter is still effective to hold the tensioning link 82 with its hook 83 out of the path of the stud 81, and since the bolt 130 remains in this position throughout the totalizing operation, the links 85 and 82 will also be retained in their respective positions, just described, throughout the operation kto prevent the drive lever 72 from lowering the tensioning link 82 to cock the total lever restoring mechanism which, therefore, remains ineffective to restore the total control lever 30, 31 at the end of the operation. The recess 1410 in the restraining link 85 is of sufficient length to enable the link to advance under the iiiliuence of its spring 92, relatively to tlielug 139, to rock the hooked tensioning link 82 through its lirststep or movement in which its hook 83 still remains out of the path of the stud 81, when the total control lever 30, 31 is rocked out of its add position. But the lug 139 withholds the restraining link in its intermediate eective position, the automatic rocking of the lever 89 through its second step of clockwise travel operating to shift its stud 87 along the slot in the restraining link 85. The stud 87 restores the restraining link 85 to the limit of its travel towards the right, under this arrangement, only when the total control lever 30, 31 is manually restored to its normal add position.
If the totalizer from which the total is to be taken, is selected under the control of the transaction key 145 in the 1 position, the finger 135 holds the bolt 130 out of the recess 140 to enable the automatic restoring device for the total control lever 30, 31 to function at the end of the operation. But if the totalizer is selected under the control of the 2 yto 9 keys, inclusively, the differential mechanism rocks the linger 135 out of contact with the stud 133 permitting the spring 129 to urge the lug 139 into the recess 140 to disable the automatic restoring mechanism.
Modified control A modification of the transaction key control is illustrated in Fig. 6 of the drawings.
In this form of control, a stud 195 projecting from the upper end of a bolt 196 mounted to slide on guide studs 197 and 198 projecting from the side frame 31 of the machine, projects through an opening (not shown) in the frame and cooperates with a recessed control disk 199 fast on the shaft 136 and differentially rotatable therewith under the control of the transactions keys 145, as heretofore explained. The control disk 199 may be differentially adjusted to a number of positions equal to the number of transaction keys plus one, which is the Zero position. lVhen the machine is operated, the control disk 199 rotates to bring the position on the periphery thereof corresponding to the key depressed beneath the stud 195 in the bolt 196. This bolt operates in t-he same manner as does the bolt 130, heretofore explained, to disable the automatic restoring means for the total lever, the bolt having a projection 200 which may be accommodated in the recess 140 in the restraining link 85. ln this modified form, the periphery ot the control disk 199 is recessed according to a predetermined plan, so that when one of the recesses is positioned beneath the stud 195, a spring 201 draws the bolt 196 downwardly to insert the projection 209 thereon into the recess 140 and prevent the tensioning link 82 from moving beneath the stud 8l of the drive lever 72, thus preventing the automatic restoration of the total lever to its normal add7 position at the end of the operation of the machine.
