Application May 21,

In Mexico J 6 Claims.

The present invention relates to an improvement in machines such as registers, adding machines andthe like. One object thereof has been to provide simpler purpose; and machines eminvention can be made and maintained in operative condition with substantial economies as compared to known types of machines for a similar purpose. Further advantages and beneficial effects in the manufacture and use of machines embodying the invention of this application will be apparent from an inspection of the following specification and the drawings appended thereto.

une 2, 1939 Figure 12, an enlarged view showing an intermediate position of locking devices illustrated in Figure 9.

The register and adding machine illustrated in the drawings provides among other features (1) indicator devices for exposing in predetermined positions at both front and rear of the machine numeral markings or the like representing a number or amount selected by the operator to be set up for addition in the totalizer devices, (2) totalizer devices for incorporating amounts or numbers selectively set up by the operator and means for carrying forward from one totalizer assembly to the next cumulative amounts or numbers of successively higher orders, as units to tens, ten to hundreds, etc.; (3) mechanism for resetting the totalizer devices to zero position; and (4) devices providing a positive stop to conclude each complete cycle of indicating and totalizing operation.

Said tens transfer mechanism and associated devices whereby cumulative amounts or numbers of successively higher orders are carried forward are set forth and claimed in my co-pending application, Serial No. 349,164, filed August 1, 1940, which, as to this subject matter, constitutes a continuation in part of the present application.

The embodiment of my invention shown in the drawings comprises a suitable frame including vertical side walls A andB mounted on a hollow base C, Figure 1, within which is a drawer D. A casing E of any desired or necessary shape resting on base C, encloses the walls A and B and the mechanism supported thereon. In the upper portion of casing E are front and rear openings, as windows, F and G, respectively, Figure 4, for viewing numerals presented at said openings by operation of the setting and indicator devices; and in the front wall is an opening, as a window H, for viewing numerals, representing totals, presented at said opening by operation of the setting and totalizer devices.

The front wall of easing E is also provided with vertically arranged slots K accommodating manually operated setting levers, and with a vertically arranged slot L accommodating a manually operated resetting lever.

Closely adjacent to each said slot K is a series (ten) of numeral markings 09 inclusive arranged parallel to longitudinal edge portions of the slot so that the setting levers may be selectively positioned by reference to said markings in a manner to be described. After each such setting, the mechanism of the machine is actuated by suitable means, such as the crank M.

Figure 1 illustrates a form of machine equipped for setting up and indicating numbers or amounts up to three digits, 1. e. units, tens and hundreds. The totalizer shown, however, includes additional cylinders to accommodate cumulative totals in terms of thousands and ten thousands. Obviously such a machine may be equipped to handle numbers or amounts of any desired number of digits in the indicating and totalizing devices, or either of them.

The machine shown in Figure 1 comprises a main shaft 1 journaled at one end (left) in a hub 2 of wall A. Wall B has a hub 3 extending outwardly through casing E. A stud shaft 1, journaled in hub 3 is recessed at its inner end to journal the other (right) end of main shaft l; and crank M is secured to the outer end of stud the ten numeral positions from 0-9 inclusive on cylinder 24. Thus, when a lever 29 is deflected to a position opposite 6, for example, on the units scale, cylinder 24 in the units column of the indicator is rotated to bring numeral 6 thereon into position at window F By a suitable well known construction, cylinders 24a are connected to rotate with cylinders 24 to indicate at rear opening G the same number indicated at front opening F.

The setting or positioning of levers 29, and

- therefore the corresponding rotation of gears 28,

shaft 4 which also carries at its inner end a gear 5 forming part of a driving train of gears.

As seen more clearly in Figure 9, gear 5 meshes with gear 6 which drives gear 1, the ratios shown being -10-40, or such that two complete turns of gear 5 produce one complete turn of gear I.

A gear 8 for actuating shaft I is secured on said shaft, as by a pin 9, Figure 1, and is rotated a quarter turn (90) first clockwise, Figures 4 and 9, and then counterclockwise during each complete rotation of gear I. For this purpose, a link l0, connecting said gears, is pivoted at l l on gear I and at l2 on gear 8.

Gear 8 also meshes with pinion l3 loosely mounted on shaft l4 and thereby actuates a gear i5 on a cam shaft IS. A recess H in said shaft adjacent to gear l5 presents a longitudinally extending shoulder 18 positioned to be engaged by a pawl 19, Figure 9, on a pawl arm 29 pivoted to gear 15 at 2| and held yieldingly in operative position by a spring 22. With gears 8, l3 and iii in the ratio 40-20-10, it is clear that, when gear 8 initially rotates a quarter turn clockwise, gear IE will rotate a full turn clockwise without turning cam shaft 16; but, when gear 8 is reversed a quarter turn by the driving mechanism above described, gear it, through pawl 19, will rotate cam shaft I6 counterclockwise to actuate cams for a purpose hereinafter to be explained.

Referring to Figures 1 and 6, an axle 23 is supported at its ends in the walls A and B. Indicator cylinders 24 and 2400, each having the numeral markings 0-9 inclusive on its outer periphery and being loosely mounted on said axle 23, are rotated the necessary extent and direction to bring any selected digits thereon into position opposite the front and rear openings F and G respectively, Figure 4, the selected digits on cylinders 24 (right) Figure 1, being visible through the front opening F and those on cylinders 24a (left) being visible through rear opening G at the same time.

Each of the independently rotatable indicator cylinders 24 is secured to or driven by a gear 25 meshing with pinion 26 mounted on a shaft 21 and rotated to the required extent by a manually actuated setting gear 28 loosely mounted on main shaft I. For this purpose, gear 29 is provided with an operating lever 29 arranged with its outer end or handle portion exposed through one of the slots K. in casing E. A pointer 30 extending laterally from each lever 29 rides freely over the corresponding scale of numeral markings arranged along edge portions of slots K.

In connection with the indicator devices above described, the ratio of gear 28, pinion 26 and gear 25 is -20-10; and the parts are so calibrated that one tooth of gear 25 corresponds to each of as above described is also the initial step in the operation of totalizing devices including totalizing cylinders, as 3| loosely mounted on a totalizer shaft 32. For this purpose, each of said gears 23 is provided near its periphery with a laterally extending trip 33, Figure 11, the angular or set position of which determines to what extent any corresponding totalizer cylinder 3| will be rotated to add a selected number to the previously established total represented by markings visible at opening H.

As seen more clearly in Figures 1 and 4, totalizer shaft 32 has a longitudinally extending groove presenting a shoulder 34. Cylinder 3| has at one side a pawl arm 35 pivoted at 39 and provided at one end with a pawl 31 which is yieldingly pressed against the periphery of shaft 32 by a spring 38. At the other side of cylinder 3!, is a, gear 39 secured to said cylinder 3! and also free on said shaft 32. Gear 39, and consequently totalizer cylinder 3|, is rotated by a gear til mounted to rotate freely on main shaft I. Gear 40 is actuated by suitable means hereinafter described to an extent controlled by the manually set position of a trip 33 on said trip carrier or gear 23.

As appears more clearly from Figures 1, 4, 6 and '7, a pawl carrier or disk 4|, loosely mounted on main shaft l between said setting gear 28 and said totalizer actuating gear 40, and which has a peripherally located stop 42, Figures 6' and 11, positioned in the path of movement of trip 33 on setting gear 23. Thus, when said trip carrier or gear 28 is manually rotated, as from its upper end position to an intermediate set position by deflecting lever 29 secured thereto, trip 33 immediately engages stop 42 on said disc 41 and. pushes said stop along ahead of it to the angular position in which the trip is set to the desired number. A pawl arm 43 is pivoted at 44 on pawl carrier disk 41 and has a pawl 45 at itssouter end and extending laterally therefrom across the periphery of the adjacent totalizer gear 40. It will be noted from Figures 6 and 11 that trip 33 on indicator and setting gear 28 also extends laterally from said gear 28 past the face of stop %2 and into the path of movement of pawl arm 43 which is controlled by a spring 46 to bias pawl 65 toward gear 43. However, during said setting movement of gear 28 and disk 41, trip 33 also engages a portion of pawl arm 43 and deflects its free end outwardly against tension of said spring 46, thereby holding pawl 45 clear of the teeth of gear 40 during said setting movement. A spring 41 secured at one end to a transverse rod 58 and at the other to pawl carrier 4! at 49, tends continuously to rotate said pawl carrier 4! counter-clockwise, Figure 6, to the extent of its movement in that direction as limited by a longitudinally extending shoulder 50 of a groove 5| in shaft I. Actual engagement with said shoulder 50 is effected by a stop 52 extending through an opening I53 in a collar I54 secured to or forming part of disk 4|, said stop being held with its inner end yieldingly engaging shaft by a spring I55.

A typical set relation of the parts above described is therefore as follows: When set as shown in Figure 4, that is with lever 29 in position at the top end of its slot, opposite units digit 9 for example, the spring pressed stop 52 of disk 4| adjacent to setting gear 28 extends into groove on shaft and with one edge engaging shoulder 50, thus determining one end position of rotation of said disk 4| The next lever, as 29a, Figures 1 and 11, associated with the tens occupies a diiferent angular position opposite the tens numeral 50 for example, this being an intermediate angular position of disk 4| to which the latter has previously been moved by manual setting movement of handle 29a. The spring pressed stop 52a of the corresponding setting gear 28, i. e. the tens gear 28, is angularly spaced from stop 52, as shown in Figure 4. The trips 33 of these several setting gears 26 when moved by levers 29, 29a, etc. respectively, occupy corresponding different angular set positions. Thus, in being moved from the 9 position to any lower or different angular position, each trip 33 deflects a pawl 45 away from the teeth of its corresponding gear 40 and engages and bears against a peripheral stop 42 of a disk 4| as previously described, to rotate the latter to a set position where pawl arm 43 remains with its pawl 45 in raised position, i. e. out of operative engagement with any tooth or interdental space of a corresponding totalizer gear 40, Figure 4, and ready to be deflected into such operative position upon the next actuation of disk 4| by shaft I through crank M and the driving train previously described.

Remembering that the total rotation of shaft is 90", it will be apparent that upon the initial complete turn of crank M, shaft I will rotate clockwise bringing longitudinal groove 5| and shoulder 50 to the dotted line position shown in Figure 4. In so advancing, said shoulder first engages the stop 52 and advances said stop and the corresponding pawl carrier disk 4|. Shoulder 5!] next engages the stop 52a and its corresponding pawl carrier disk 4| and so on, the order of engagement of the several stops 52 depending on their respective angular positions. However, as soon as a carrier disk 4| starts to rotate, its pawl 45 is moved beyond and therefore disengages the corresponding trip 33 and, when thus released, is deflected by operation of spring 45, into the next interdental space on totalizer gear 40 to engage and rotate said gear with said disk 4| to the end of the 90 clockwise rotation of shaft For reasons hereinafter explained, the initial full turn of crank M is followed at each operation of the machine by a second or concluding full turn. However, during said concluding full turn of crank M, the direction of rotation of shaft is counterclockwise to restore shoulder 50 to its normal initial angular position, as shown in full lines in Figures 4, 6 and 7.

During said return or reverse rotation of shaft the pawl carrier disk 4| follows in rotation under tension of spring 41 until stop 52 reaches the position shown, 1. e. corresponding to the 9 digit position of lever 29, Figure 4. The other carrier disk, as 4|, having stop 52a, follows along with the reverse rotation of shaft to the angular position indicated by said stop 52a, the 50 position. At this point, the stop 42 on carrier 3 disk 4| reengages trip 33 on corresponding setting gear 28. This arrests return movement of the pawl carrier disk 4| and disengages pawl 45 from the teeth of totalizer gear 40 over which the pawl 45 was riding until thus stopped and disengaged. Obviously shaft continues return movement to its zero or initial position, regardless of the set or selected positions of any of the levers 29 and connected indicator devices, which remain as set until the operator again moves said levers 29 or any of them to different selected positions.

My improved apparatus also includes accumulator devices for rotating a totalizer cylinder representing a higher order of digits or numbers one part turn, one digit, for each full turn, ten digits, of the totalizer cylinder representing the next lower order of digits or numbers.

For this purpose, four trips 53 angularly spaced extend laterally from one face of gear 40 near its periphery, so that during successive increments of rotation of said gear, each of said trips on passing a fixed point will mark the passing of ten gear teeth on gear 40 corresponding to ten digits added on the associated totalizer cylinder 3|.

As shown more clearly in Figures 4 and 7, the trip-s 53 on each gear 40 are positioned to successively actuate a latch 54 having an upper cam edge 55 arranged in the path of said trips 53. Said latch 54 is supported and guided for vertical movement between a transverse rod 56 having an annular latch guiding groove 51 and a transverse shaft 58 having an annular latch guiding groove 59. Latch 54 has an upper slot 66 edge portions of which ride in groove 51 and a lower slot 6|, edge portions of which ride in groove 59. A spring 62 having one end secured to rod 55 and the other to latch 54 normally holds the latter yieldingly in the elevated position shown in Figure 4. Latch 54 also has a laterally extending obliquely disposed detent 63 an inner inclined face of which, when in the position shown in said Figure 4, normally engages a pin 54 extending laterally from a pawl arm 65 pivoted at 65 on a rocking lever 61. Pawl arm 65 has a pawl 68 at its upper end and extending laterally therefrom (to the right Figure 3) to a position opposite and normally spaced from the teeth of that gear 40 which actuates a totalizer cylinder 3| bearing numbers of the next higher order. A spring 69 with one end secured to said rocking lever 61 and the other to pawl arm 65 normally biases pin 64 on said pawl arm 65 todescribed yielding engagement inclined face of detent 63 on Said rocking arm 61 is loosely mounted to rock on shaft 4 and is actuated by a cam 16, secured on cam shaft l6, against tension of a spring 1| having one end secured at the lower end of said rocking lever 61 and the other to a transverse rod 12.

As shown more clearly in Figure 7, when a trip 53 on a totalizer gear 40 engages the cam edge 55 of latch 54, the latter is pressed downwardly against tension of spring 62, thus carrying detent 63 below the level of pin 64 on pawl arm 65. Spring 69 now causes said pawl arm 65 thus released from detent 63 to rock clockwise; and pawl 63 moves into engagement with an interdental space of the next adjacent totalizer gear 40 representing numerals of the next higher Meanwhile, as soon as trip 53 on said gear of lower order clears the upper end of latch 54 which occurs with the passing of each tenth latch 54.

tooth of said gear, the unlatching movement shown in progress in Figure 7 is completed and said latch immediately returns, under tension of spring 62, upward toward its initial or up position, shown in Figure 4. Pin 64 is now to the left of detent 63 to an extent determined in part by the angular position of pawl arm 65 when pawl 68 is moved into engagement between adjacent teeth of gear 40 by spring 69 upon relseaase, as above described, of pin 64 from detent This release of pawl arm 65 and the consequent setting of pawl 68 into engagement with gear 40 of the next higher order is effected during the colckwise rotation of main shaft previously described and which takes place during the initial full turn of crank M. During the concluding turn of said crank and the reverse rotation of main shaft I, camshaft I6 is rotated counterclockwise by gear l5, Figure 9, one full turn so that a cam 10 on said shaft l6 will be rotated 360, during which movement, it deflects the lower end of rocking lever 61 against tension of spring H to the dotted line position and back to solid line position as shown in Figure '7. This motion of said lever 61 first imparts an upward thrust to pawl arm 65 and, through pawl 68, causes the totalizer gear 40 engaged thereby to rotate the angular space of one tooth and hence produces a corresponding rotation (one digit) of the associated totalizer cylinder 3|, in addition to such independent rotation thereof as may have been imparted to it by operation of the selective totalizer actuating devices previously described. This upward thrust of pawl arm 65 carries pin 64 upwardly past the left edge or outer face of detent 53 on latch 54 and into an end position just above the level of the upper edge of said detent 63. The relative positions of pawl arm 65, lever 61 and cam 10 at this point in operation of the machine are however as shown in dotted lines in Figure '7. Meanwhile cam 10, continuing counterclockwise rotation back to its initial solid line position, permits lever 61 to be returned to its initial (solid line) position under tension of spring I At the beginning of this return movement, the gear engaging end portion of pawl 68 rides outwardly and over the outer end of the gear tooth next below said pawl in its gear advancing position. This first deflects pawl arm 55 counterclockwise an additional amount and so that pin 64 is thereby moved toward the right past the upper edge of detent 53 to the dotted line position, Figure 4, and then moves into its initial position (Figure 4) against the inner inclined face of said detent as said lever 61 resumes its full line position. Thus for any order of numbers above units, the selected number or value is added at each operation of my improved machine to a corresponding totalizer cylinder 3| during the initial full turn of crank M; and any accumulated ten value is thereafter added thereto during the concluding full turn of said crank, so that when the latter comes to rest after each complete double turn, the totalizer cylinders will reveal, at window H, numerals representing the total of all numbers added.

As indicated more clearly in' Figures 3 and 4, the cams I are mounted within an angle of 180 on shaft N3 in spaced and angularly staggered relation so that the units to tens cam 10, at the left, Figure 3, will operate first and will be followed in succession by the tens to hundreds, hundreds to thousands etc. cams as rotation of shaft l6 continues. This arrangement insures that each transferred unit of a lower order will be included in the transfer or carry of ten units of the next higher order.

An adding device according to my invention also includes mechanism for resetting the totalizer cylinders 3| to zero position. As shown more clearly in Figures 1 and. 8, a resetting main gear 173 is loosely mounted on main shaft and meshes with a gear 14 secured on totalizer shaft 3|. One end of an operating handle 15 is secured to gear 13 and its other end extends through slot L in casing E. A stop 16 limits upward movement of said handle and another stop 'i'i limits downward movement thereof. Gear 14 has ten teeth corresponding to a like number on gear 14 and on the gears 39 attached to the totalizer cylinders 3|. The previously described pawls 31 on said cylinders, Figure 4, bear a fixed radial relation to the numeral markings on the peripheries thereof, being approximately in radial alignment with the zero marking in each case. It will be clear that, if totalizer shaft 32, Figure 4, is rotated counterclockwise a full turn, the shoulder 34 will move into engagement with pawl 3'! of each cylinder 3| and thereby rotate all of the cylinders 3| to whatever extent may be necessary to bring all of their respective zero markings simultaneously into transverse alignment, as viewed through opening 1-1 in casing E. This counterclockwise, Figure 4, rotation of shaft 32 is effected by pulling handle 15 downwardly to an extent limited by stop 11, Figure 8. thus rotating resetting gear 13 in the direction of the arrow thereon in Figure 8. When handle 25 is returned to up position as limited by stop l5, shaft 32 rotates in reverse direction but in view of the arrangement of pawl 31 on said cylinders 3| in relation to the shoulder 34 of said shaft, all of said cylinders 3! remain in reset or zero position.

On the down stroke of resetting handle 15 the cylinders 3| are rotated in the same direction as during normal adding operation and therefore transmit equivalent motion to the corresponding gears 40 and trips 53 thereon, with consequent effect on latch 54 and, unless prevented, on. associated accumulating devices when operating handle M is next turned as above described. To prevent this operation of said accumulating devices during resetting, the pawl arms 65 are restrained from rocking when the detents B3 disengages pin 5 incident to passage of trip pins 53 across the cam edge or nose 55 of latch 54. For this purpose, deflector arms 18, Figure 4, are secured on shaft 58 and rotate therewith during rotation of resetting gear 13 to the dotted line position shown in said figure, ThlS position is reached just before latch 54 reaches the position at which pin 53, in a normal transfer operation, is freed from detent 54. As seen more clearly in Figure 8, a crank 19 secured to said shaft 53 is yieldingly biased toward its inoperative angular position by a spring 89. A link 8| connects said crank 19 with resetting gear 13, so that when the latter is rotated in resetting, shaft 5% rotates and swings the ends of deflector arms 15 into engagement with the lower ends of corresponding pawl arms 65 which are thus restrained from swinging pawls as into position for engaging the teeth of associated gears Ml. It will be clear from Figure 4 that, while pawl arm 65 is held from moving to the deflected position by said deflector arms T3, the pin 64 on said pawl arm remains in position to be immediately reengaged by the inner inclined face of detent 63 when latch 54 returns to its up position, Figure 4, after passage of trip 53 across the top edge or nose 55 of latch 54 during resetting and while pawl arm 65 is in said restrained position said pawl arm 65 will not rock to engage pawl 68 with the teeth of gear 40.

Accidental or inaccurate turning of totalizer gears 40 is minimized by suitable friction or damping rollers 82 riding on the teeth of said gears and mounted on levers 83 pivoted on a transverse rod 84. Springs 85 each with one end secured on transverse rod 86 and the other end secured near one end of levers 83 hold the rollers 82 in yielding damping engagement with the teeth of their respective gears 40.

The machine shown in the drawings includes devices which automatically stop rotation of hand crank M at the end of its second or concluding turn, more particularly to prevent the operator from inadvertently recording or regismode of operating the machine.

As shown more clearly in Figures 1, 9 and 12, the stud shaft 4 has a collar 81 with a spirally contoured peripheral surface and a shoulder 83 interrupting said surface. Closely adjacent to said collar, a stop 89 projects inwardly from wall B. A latch lever 99, provided with a slot 9| is slidably and rotatably supported on wall B by a pivot pin 92. The upper end of latch lever 90 has a notch 93 and a laterally extending detent A spring 95 with one end secured to wall B at 99 and the other to latch lever 90 at 9'! biases said latch lever 90 toward its normal inoperative position, indicated in dotted lines in Figure 9, notch 93 engaging stop 89 and with hook I03 disengaged from shoulder 88. As shown in Figure 10, gear 8 carries a rocking trip arm 98 pivoted at 99 and having a laterally extending trip I which cooperates with arm 94 in a manner to be described. A spring IOI holds trip arm 98 yieldingly against a stop pin I02 and these parts when normally inoperative occupy the positions shown in Figure 10, relatively to arm 94.

On the first 360 rotation of crank M, gear 8 initially rotates 90 clockwise, Figure 9, carrying with it to an end position indicated in dotted lines trip I90 which yields as its inclined upper edge rides against the under edge of said arm 94, (dotted line position); and the shoulder 88 of collar 8? passes clear of hook I03 (dotted line position).

On the concluding 360 collar 81, counterclockwise, the direction of rotation of gear 8 and trip I 00 is reversed to counterclockwise, as viewed in Figure 9; and said trip I00, now prevented from yielding by stop I92, reengages arm 94 camming the same upwardly and to the left and thus rocks the upper end of latch lever 90 to the leftand upwardly releasing notch 93 thereof from stop 99. Said upper end of latch lever 90 now cannot rock to the right because its under edge is engaged by stop 89. Said latch lever 90, therefore, slides endwise upwardly across stop 89 under 95 to an intermediate position,

turn of crank M and as viewed in Figure 9,

92; and hook I03 at the lower 99 swings toward cam surface 87 and into position to be presently engaged by shoulder 88 WhlCh in returning to the position shown in Figure 9 reengages hook I03 and thus endwise downwardly until full line position of latch lever 90, Figure 9) the upper end of slot 9| is engaged and stopped by pivot 92. This stops further rotation of collar 81 and consequently of crank M. As soon as the operator releases said crank M, spring causes hook I03 to become disengaged from shoulder 88 whereupon, by reason of the eccentric pull of spring 95 which is secured to latch lever 90 below and to the left of pivot 92, said latch lever 90 rocks clockwise, Figure 9, back to its initial inoperative (dotted line) position with notch 93 engaging stop 89. It will be apparent that latch lever 90 can not, at this stage of operation, move to the intermediate position shown in Figure 12, but must take the position just described and as shown in dotted lines in Figure 9 because, when hook I03 is released from shoulder 88, the tip end thereof can not swing inwardly (right) being obstructed in this direction by the periphery of the collar ad- J'acent to shoulder 88. The latch lever 90, therefore, can not swing counterclockwise sufficiently for its upper end to clear the end of stop 89.

pulls latch lever (as shown in the The situation is different when, during return,

movement (left, Figure 12) of trip I00, the latter dislodges the upper end of latch lever 90 from when the trip I00 dislodges notch 93 from the stop 89 so that said notch 93 clears the end of stop 89, thus permitting the latch lever 90 to slide up on stop 89 to the position shown in Figure 12 under tension of spring 95.

Where my improved apparatus is embodied in a mac received is being rung up, i. e. recorded on the totalizer. For this purpose a bell I04, Figures 1 and 8, is struck by a clapper I05 upon each first turn of crank M, said clapper I 05 being mounted on an arm I96 secured to a shaft I 01 which rotates freely in one direction under tension of a spring I08. I09 is secured to shaft I 01 of gear 1. Thus, during rotation of said gear 1., tri II 0 engages and deflects arm I09 and rotates shaft I0'I a corresponding extent. When trip IIO passes and releases arm I 09, shaft I01 and clapper arm I06 rotate back toward normal position under tension of spring I08 thus causing clapper I 05 to strike bell I04.

Where the machine is used as a cash register and repository, the cash drawer D is locked and released by any suitable means. As shown in Figures 1 and 4, a latch lever I II is loosely mounted to rock on shaft I 01. Its lower end II 2 normally lies in the path of position, moved outwardly by spring II 3. On its return to closed position the rear edge of the rear wall of drawer D bears upwardly against the lower inclined edge 'Hli'of lever Ill and deflects said lever in passing to the normal locked position as shown in Figure 4.
