CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 591 ,748, dated October 12, 1897. Application filed January 23, 1897. Serial No. 620,398. (No model.)

T0 at whom it may concern:

Be it known that 1, WILLIAM J. ENswoR'rH, of Erie, in the county of Erie and State of Pennsylvania, have invented a new and Improved Gash-Register, of which the following is a full, clear, and exact description.

This invention relates to an improvement in that class of cash-registers. by which the amount of each sale is visually indicated and at the same time cast into an aggregate register of the sales, so that the machine will always indicate at its registering mechanism the amount of cash which should be in the drawer.

The invention consists in such peculiar features of construction and combination of parts as will be fully described hereinafter and defined in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

' Figure 1 is a fragmentary plan of the invention, parts being shown in section. Fig. 2 is a front elevation with parts broken away to disclose the interior. Fig. 3 is a vertical longitudinal'section, and Fig. 4 is a similar view showing the parts in different positions. The casing or frame of the register has a bottom 5 with four vertical sides 6 and a sheet-metal top 7, shaped to conform with the mechanism within the casing. Slidable longitudinally on the bottom 5 is a cash-drawer 8, having an expansive spring 9 normally pressing against the rear-wall 6 and serving to project the drawer forwardly when the drawer is released. A horizontal plate 11 is held within the casing and has its inner portion 12 separated from the outer portion and pivotally connected thereto by a hinge 13. The movable plate 12 is capable of dropping downward when the drawer 8 is moved outward, as shown in Fig. 4. Pivoted on a rod 14, running transversely within the casing and directly adjacent to the rear wall thereof, is a transversely-elongated shoe 15, projecting over the rear edge of the movable plate 12 and having rigidly connected therewith a catch 16, which extends downward through an opening in the rear stationary portion of the plate 11. The catch 16 is adapted to enter an opening 17 in a plate 18, secured to the upper rear portion of the drawer 8. By these means the drawer is normally held within the casing against the tension of the spring 9. The rod 14 is located at the top of the rear portion of the stationary plate 11 and is pressed so as to throw the catch 16 downward by means of a spring 19. (Shown in Figs. 3 and 4.)

Mounted within the casing is a revoluble transverse shaft 20, located approximately midway the length of the casing and above the portion 12 of the plate 11. shaft 20 is a large wheel 21, the periphery of which is provided with numerals divisible by five and running from 5 to 100. These numbers represent cents in the record kept by the machine. Fixed to the shaft 20 is a lug '22, adapted to engage with teeth formed on the periphery of a wheel 23, mounted on a counter-shaft 24, held in the casing. The periphery of the'wheel 23 is also provided with numbers running consecutively from l to 100, and representing dollars in the record kept by the machine. A single revolution of the shaft 20 advances the wheel twenty-three one-hundredths of a revolution by the engagement of the lug or projection 22 with the teeth on the wheel 23. Fixed to the shaft 20 is a pinion 24, having a comparatively large number of small teeth. Adjacent to the pinion 24 is a pinion 25, fixed on the shaft 20 and having a diameter greater than that of the pinion 24 and also having larger and less numerous teeth than the pinion 24. A still larger pinion 26 is fixed to the shaft 20 adjacent to the pinion 25, and a pinion 27 is fixed adjacent to the-pinion 26, which pinion 27 is also larger than the pinions previously described. The remainder of the shaft 20 is occupied by a transversely-e101]gated drum 28 with teeth and diameter coextensive with the teeth and diameter of the pinion 2'7.

Carried longitudinally on the upper side of the movable plate 12 are a series of dovetailed cleats 29, which form parallel guideways wherein the rack- bars 35, 30, 31, 32, 33, and 34 respectively run. The rack-bars 35 all mesh with the drum 28, and the number of teeth on each rack-bar 35 is gradually diminished from the rack-bar which is far- Fixed to the thest to the left. The rack-bar S5 farthest to the left, which has the greatest number of teeth, stands for 95 cents, which is nearlya complete revolution of the drum 28. The imi'nediately-adjacent rack-bar 35 is capable of registering cents, and therefore causes a revolution of the drum 2S slightly less than a revolution brought about by the movement of the rack-bar farthest to the left, so the diminution runs until the rack-bar farthest to the right and having the least number of teeth stands for cents and turns the drum 2S one-twentieth of a revolution. The rack-bar 3O meshes with the pinion 27 and has a single number of teeth to turn the shaft a single complete revolution. The rack-bar 3O stands, therefore, for $1. The rack-bar 31 meshes with the pinion 2G and hasa suffieientlnnnber of teeth to turn the shaft 20 two complete revolutions. The rack-bar 31 stands, therefore, for $2. The rack-bar 32 meshes with the pinion and turns the shaft 20 three revolutions and stands for $3, and the rack-bar 33 meshes with the pinion 2 L and turns the shaft 20 four revolutions and stands for tit. The rack-bars 31-, according to the specific arrangement here illustrated, are superfluous, but they may be provided with teeth increased in number over those on the rack-bars 33, so as to register $5 and $6, if desired. Each rack-bar has an elevation sufficient to cause its teeth to properly mesh with the respective pinions or drum, as may be seen by reference to Fig. 2. The rack-bars 35 (shown outside of the cover-plate '7 in this View) are sectioned on a line forward of the rack-bars shown inside of the cover-plate 7. All of the rack-bars at points normally outside of the cover-plates 7 maybe made hollow, as shown at the right-in Fig. 2, for convenience in manufacturing. Located within a cavity in each of the rack-bars is aretractile spring 36. One end of each spring-ltiisfixed to its respective rack-bar, and the other end of each spring is fixed to the forward portion of the plate 11. These springs serve to hold the rack-bars in a forwardmost position, as shown by full lines in Fig. l. rearward to actuate the shaft 20, they move against the tension of the springs 36. As the rack-bars approach the limit of their rearward movement the inclined rear ends of the rack-bars, as shown in Fig. 4, engage with the shoe 15 and lift the same, as the dot-ted lines in Fig. 4: show, and this releases the drawer S by moving the catch 16 upward. Upon this operation the spring 9 asserts itself to project the drawer forwardly, as also shown in Fig. 4.. The movable plate 12 is now without support, and the action of the spring 36 on that rack-bar which has been moved rearward will cause the plate 12 to drop to the position shown by full lines in Fig. t. The plate 12 moving downward carries with it the rack-bars, which are consequently disengaged from their respective pin- When the raclebars are moved ions and drums, and the rack-bar which has been pushed rearward is permitted to return without engagement with the corresponding pinion or drum on the shaft 20. \Vhcn therefore a sale is made, the appropriate rack-bar is pushed inward, the amount of the sale is cast into the aggregate record kept by the wheels 21 and 23, and the drawer 8 is pushed forward to permit the deposit of the cash therein. Figs. and L illustrate a springpressed pawl 37, which is fixed to the rear wall of the casing and projects forwardly to bear down upon the drum 28 and prevent loose movement thereof. A similar spring 38 (shown in Fig. 1) bears upon the teeth of the wheel 23 to prevent the loose revolution of this wheel.

The top 7 of the casing is curved at an intermediate point to conform to the wheel 21, and at a point just above this curve the easing is provided with openings 3i), through which the operator may observe sale-indicating devices, which will now be described. A shaft 4C0 extends transversely above the wheel 21 and adjacent to the openings 39. Fixed to this shaft 40 is a series of right-angled plates 4K1, on the adjacent faces of each of which are printed numbers respectively corresponding with the raelebars. Each rack bar is provided at the point above its spring 36 with a rising-and-falling cam These cams -12 are arranged to engage the lower bar t3 of a frame it, slidable diagonally in supports and 46. hen one of the rack-bars is pushed rearward, its cam L2 engages the lower bar -13 of the frame at-f and causes the frame to move upward. Should any of the plates ll be in the position shown by dotted lines in Fig. 3 and by full lines in Fig. l, the upper bar L7 of the frame el; t will engage with such plate il and swing the same to the position shown by full lines in Fig. 3 and by dotted lines in Fig. at. hen in these positions, no number is visible through the openings 39. Bars at one for each rack-bar, slide independently in the support -f5 and. in an additional support 41!). Immediately after the cam on that rack-bar which has been operated passes the bar 4- 3 the frame -i-lwill return to its lower position and the cam will then ongage its corresponding bar l8 and push this bar up independently of the other bar 48, so that that angle-plate t]. which is actuated by the bar t8 that has been moved will be thrown to the position shown byfnll lines in Fig at and by dotted lines in Fig. 3,which position issueh that a number will appear through the corresponding opening 39, which number will correspond with the amount for which the rack bar that has been operated stands. When the rack-bar returns, its cam 4-2 again engages the frame -.i--l and operates the same to throw that plate 41 which has just been operated into a position at which it will. show no number through the corresponding open ing 3.

By the mechanism just described I have ICC) , for the register of sums divisible by five.

provided a register which has a cash-drawer to receive the cash and which casts into an aggregate register all sales that are made. The cash-register also displays the amount of each sale individually at the moment of its register. The form shown is adapted only It is obvious, however, that this can be changed to make any number registerable.

In using the invention the operator pushes inward the rack bar bearing the number which corresponds with the sale the operator has made and permits the drawer 8 to be shoved forward by its spring 9. The cash may now be deposited within the drawer'S and the drawer then returned. As the drawer is moved forward the plate 12 drops to permit the operated rack-bar to return, and immediately before its return the registering mechanism will have been moved to cast the sale into the sum of all of the sales.
