CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 535,083, dated March 5, 1 895.

Application filed March 15,1894. Serial No. 503,686. (No model.)

To ctZZ whom it may concern:

Be it known that I, ELIJAH F. SPAULDING, a citizen of the United States, and a resident of Bound Brook, in the county of Somerset and State of New Jersey, have invented certain new and useful Improvements in Cash- Registers, of which the following is a specification.

The invention relates to improvements in cash registers, and consists of a register embracing the novel features of construction and combinations of parts hereinafter described and particularly pointed out in the claims.

The object of the invention is to provide a cash register which shall be simple and durable of construction, capable of being readily understood and operated, accurate, safe, and possible of manufacture and sale at a figure which will admit of its use by persons who do not employ the expensive registers at present on sale.

Referring to the accompanying drawings forming a part'of this specification: Figure 1 is a front View of a cash register constructed in accordance with and embodying the invention. Fig. 2 is a vertical section of same on the dotted line 2-2 of Fig. 1. Fig. 3 is a similar section of a detached portion of same on an enlarged scale and illustrating the operative parts in a position different from that shown in Fig. 2. Fig. 4 is a vertical section of same on the dotted line 44: of Fig. 2, said Fig. 4 being substantially a frontview of the cash register, with the front of the register removed for the purpose of disclosing the interior mechanism thereof. Fig. 5 is a vertical section of said register on the dotted line 5-5 of Fig. 2 and showing in detached form the mechanism for registering the amount of sales. Fig. 6 is a detached top view of the mechanism illustrated in Fig. 5. Fig. 7 is an enlarged transverse section of a portion of the machine on the dotted line 77 of 1, and Fig. 8 is a transverse section through a portion of the machine on the dotted line 88 of Fig. 1, said Fig. 8 being intended particularly to show the form of the shutter which conceals the numbering wheels, except at such time as the owner of the machine may desire the shutter removed for the purpose of disclosing to him the total amount of sales at any definite time.

In the drawings A designates the main exterior frame of the machine, and B the cash drawer below said frame. The frame A is composed of a base O, front-face D, back E, ends F and vertical extensions G, the latter being provided for the purpose of permitting the movement of the actuating slides hereinafter referred to.

Between the front face D and the back E of the frame of the register are secured a tilting frame H and a series of vertical actuating slides I, J, K, L, which slides are more clearly illustrated in Fig. 4E and are in the form of vertical tablets numbered from O to 9 inclusive. The slides I, J, K, L, are each provided on their rear face with a rack M, illustrated more clearly in Fig. 2 by full lines and indicated in Fig. l by dotted lines, and each of said slides is also provided with a handle N projecting forward through the face D in convenient position to be grasped by the attendant.

In the face D of the frame of the machine are provided the vertical slots 0 through which the handles N project and which serve to guide the same during their vertical movement. Between the pairs of slots O, the face of the machine is provided with the indicating plates or tablets P, Q, numbered, as illustrated in Fig. 1, from 9 to 0 inclusive and provided with the indicating ribs or marks R in line with the numerals on said plates. The handles N projecting forward through the slots 0, are each provided with an index finger S, which, during the operation of recording the amount of sales, will be carried upward in line with the numerals on the plates P, Q, as hereinafter explained, and during such movement the ribs or marks R will serve to guide the attendant in bringing the said index fingers S in direct alignment with the numerals on said plates P, Q.

In the front-face D of the frame of the machine and directly over the plates Q, P, thereof are the apertures T, U, V, \V, which are in alignment with the upper ends of the slides I, J, K, L, and when said slides are in their lower position disclose the cipher at the upper ends thereof, and when said slides are elevated so that the index fingers S reach any special figures on the plates P, Q, the corresponding figures on the slides will be disclosed at the said apertures T, U, V, V, and indicate to the purchaser the amount being registercd.

In rear of the vertical slides I, J, K, L, is pivot-ally mounted the frame II, indicated more clearly in Figs. 2 and 5, the said frame being secured by pivots a, to ears 1) cast upon the inner face of the front D of the machine. The frame H is composed of the vertical side bars d, c, the upper transverse connecting bar f, and suitable lugs which need not be especially referred to, for supporting the numbering wheels lettered, respectively, g, 7L,i,j and 7t, as illustrated in Fig. 5. The pivots a are below the horizontal center of the frame H, and hence the upper portion of said frame being heavier than the lower portion thereof, will tilt when left unrestrained and I have therefore called the frame H a tilting frame. The purpose of allowing a tilting movement of the said frame 11 will be referred to here inafter.

The wheels 71, 2,7', 7c, are numbered from O to 9 inclusive and are arranged with respect to each other so that the said wheels will add and register the amount of sales d uring a day or any other period of time, the wheel 9 registering cents up to ten; the wheel 7L registering tens or dimes up to one dollar; the wheel 2' registering dollars up to ten; the wheelj registering tens of dollars up to one hundred, and the wheel 71') registering a multiple of one hundred dollars up to ten.

The wheels 9, 7t, 71, j, are actuated to revolve in the directions indicated by arrows in Fig. 5, by means of the racks M carried by and projecting rearward from the slides I, J, K, L, asindicated more clearly in Fig. 7; and said wheels g, h, t', j, are provided with bent arms at which serve to do the carrying of the amounts from one wheel to another in succession, the said arms being more clearly shown in Fig. 7 and being so arranged that with each revolution of a wheel its arm will move the next adjoining wheel a distance equal to one tooth thereof. The wheel 79 is not provided with one of the arms 92 since the amount registered thereon is not intended to be carried to any other wheel.

In order to prevent any back movement of the toothed wheels 9, 71,2', j, the frame 11 is provided with pivoted pawls q, as shown in Fig. 5, which engage said wheels and prevent their movement, except in the direction of the arrows and in the proper operation of the machine for registering the amountof sales and carrying the same forward. The wheel has contacted with its teeth a flexed spring 0 which prevents any undue movement of said wheel. As will be more fully observed from Figs. (3 and 7 the wheels g, 7L, 1', j, 7t: are arranged at an angle with respect to the vertical portion of the front of the machine and the object of such arrangement is to prevent the arms 71 from coming into contact with each other during the revolution of said wheels. \Vhen arranged in the manner illustrated, the arms n may pass each other, as illustrated in Fig. '7, and perform their due functions without danger of meeting each other and obstructing the operation of the machine.

When the frame His in an upright position, as illustrated in Fig. 2, the teeth of the racks M on the slides I, J, K, L, will be in position to engage the teeth of the wheels 9, 7t, '11, j, upon the upward movement of the slides for the purpose of registering the amount of the sale; but when, after the elevation of the said slides and the registering of the said amount, the drawer B is pulled open to receive the money and permit the making of change, the said frame II. will, at. its upper end, tilt rearward, thereby removing the said wheels g, h, t, from alignment with the said racks M and at such time no change in the position of the numbering wheels can be made. The tilting of the frame If is accomplished simply by the pulling outward of the drawer l which leaves the frame unrestrained and permits its heavier portion to tilt rearward. As shown in Figs. 2 and 5 the arm (Z of said frame It projects downward through a slot in in the base 0 and is directly over a partition t formed in the drawer 13. The upper edge of the partition '6 is cutaway to form a shoulder 10 which, when the drawer I3 is pushed inward will come into contact with the lower front edge of the arm (I and operate to restore the frame If to a vertical position and to retain the same in such position until the said drawer is again pulled outward and the shoulder 2!] relieved from the lower end of the arm (Z, at which time the frame ll will again tilt rearward and withdraw its wheels g, It, t', j, from alignment with the racks Ill.

Upon the lower front portions of the arms (I, c, forming a part of the frame 11 are the ears as to which are pivoted the dogs 11 whose front ends are inclined and lighter than their rear ends (see Figs. 3 and 5) which are in position to rest upon the shoulder as of the back E, as shown in 2, when the frame ll is in an upright position, and to bear against the front edge of said shoulder, as shown in Fig. 3, when the frame If is allowed to tilt rearward by the opening of the drawer 13, during such time as the slides I, J, K, L, or any of them, may be in a raised position. The object of the dogs y is to prevent the frame from being restored to its upright position except when the slides l, J, K, L, are in their lower position, and thus a salesman could not when the frame is in a tilted position and the cash drawer open, move any of the slides upward and then secure it in its elevated position by the registering wheels by closing the cash drawer. hen the dogs y are in the position shown in Fig. 3 and it being assumed that the slide K is being held up by the salesman, the insertion of the drawer B would not restore the frame II to its vertical position, since the dog y pressing against the shoulder 50, would prevent such result. IVhen, however, the slide descends, it strikes the front end of the dog y and turns the rear end thereof upward from the front of the shoulder 0c, and at such time, the slide being stationary in its lower position, the insertion or closing of the cash drawer will restore the frame H to its upright position, and the slide cannot be elevated without engaging and turning the registering wheels.

In the operation of the machine the amount of sales will be recorded by the attendant by the moving upward of the slides I, J, K, L, by means of the handles N, and in accordance with the amount of sales. If a sale should amount to five cents, the attendant would elevate the slideI until theindex finger S thereof registered with the numeral 5 on the tablet or plate P, and if the following sale should amount to fifty cents, the attendant will, by means of the handle N elevate the slide J until its index finger S registers with the numeral 5 on said plate P, thus indicating a sale amounting to five tens or fifty cents; and if a sale amount to five dollars the attendant will by means of the arm N elevate the slide K until its index finger S registers with the numeral 5 on the plate Q; and if the sale should amount to fifty dollars the attendant will elevate the slide L until its index finger S registers with the numeral 5 on said plate Q. Thus for the varying amounts of sales the slides I, J, K, L, will be operated, in each instance, the index finger S being arrested at the numeral on the plates P, Q, which would indicate the amount of the sale. The upward movement of the slides I, J, K, L, actuates the Wheels g, h, t, j, in the direction of the arrows, illustrated in Fig. 5, the sale amounting to five cents causing the wheel g to revolve a distance equal to five of its numerical spaces; the sale of fifty cents resulting in the wheel 7t being moved a distance equal to five of its numerical spaces; the sale amounting to five dollars resulting in the wheelt' being revolved a distance equal to five of its numerical spaces,

and the sale of fifty dollars resulting in the wheeljbeing revolved a distance equal to five of its numerical spaces, and the said sales being indicated by the numerals on said wheels. Upon the continued sales amounting to more than ten cents or one dollar or ten dollars, respectively, the wheels g, 7t, t', j, will communicate their movement from one to the other in a well known manner in adding machines by reason of the arms a 011 one wheel engaging the teeth of the next adjoining wheel and revolving said wheel a distance equal to one of its numerical spaces. With each elevation of the slides I,J, K, L, the amount of the sale is exposed at the openings '1, U, V, \V, and may be seen by the customer; while the total amount of sales registered on the wheels g, 71 t',j, his not exposed to the customer, but may be read by the proprietor through the openings ct, Z), c, d, and e, which openings are in line with the numerals on said toothed wheels and are preferably closed by means of a sliding plate or shutter f interposed between the wheels g, 70, t',j, 7t, and the said openings. The shutter f is simply a plate of metal bent into form to pass around the slides I, J, K, L, and its shape is indicated in Figa 1 and 8. The shutter f is adapted to be operated by means of a lock g, the key to which will be held by the proprietor and the bolt 7t of which will be connected with the said shutter and upon being extended upward from its casing, as illustrated in Fig. 1, will push the shutterf upward so as to close the apertures ct, Z), c, d, and c, and when the lock g is operated to withdraw the bolt 7t into its casingthe shutterf' will be lowered a sut'ficient distance for the openings 1), c, d, and e, to be used in reading the indicating numerals on the registering wheels g, h, t', In the shutterf is provided an aperture t, as indi cated by dotted lines in Fig. 1, which aperture, upon the lowering of the shutter will come into alignment with the opening a in the front of the machine and permit the exposure of the indicating numeral of the wheel 7c. Thus upon the lowering of the shutter f, the indicating numerals on all of the registering wheels will be exposed and the proprietor may read the entire amounts of sales for any given period.

Upon the elevation of the slides I, J, K, L, their upper ends enter the extensions G formed at the upper end of the machine, and thus said slides are enabled to make their full vertical movement without obstruction.

In order to prevent any noise or rattling of the parts of the machine during the descent of the slides I, J, K, L, there is provided at the lower ends of said slides a simple form of dash-pot, as illustrated more clearly in Fig. 3, in which it will be observed that at the lower end of the slide adjoining the arm N is provided a recess or cylinder m receiving a piston n which is held in place by a pin 0' and permitted to have a vertical movement by means of the slot in said piston passing over said pin. Upon the elevation of the slide the piston n will of its own weight descend to the position shown in Fig. 3, and upon the descent of the slide the piston 'n will by its contact with the frame of the machine below it, be driven upward into the cylinder m, and thereby will be formed an air cushion which will ease the contact of the parts and prevent noise.

In practical use, when a sale is made, the drawer B is first drawn out to receive the money and permit the making of change, this operating to permit the frame II to tilt backward and the rear weighted end of the dogs y to assume a position to drop downward in contact with the front edge of the shoulder a" should any of the slides at such time be eievated and thus relieved from the front end of said dogs. Upon the money having been placed in the drawer B, the latter is closed,

' movement it will strike the front end of the dog y and thus operate to lift the rear end of same free of the shoulder :0, thus leaving the frame H in a condition in which it may berestored to its vertical position on the next insertion of the drawer. It will be observed that the registering is accomplished after a sale has been made and the money has been placed in the drawer and the latter closed.

To prevent the fraud which would ensue in case the salesman should be able to elevate a slide while the drawer is open, and then close the drawer to restore the registering wheels into position, to hold the slide without said wheels having been rotated, I have provided the dogs 1 which prevent, as above described, the drawer from being closed and the frame II from being restored to its vertical position except when the numbered slides have actually been permitted to descend to and are stationary in their lower position. Then on the closing of the drawer the frame II will assume its vertical position and the elevation of the slide or slides cannot be effected with-- out acting on the wheels to register the sale.

As above mentioned, when the drawer is pulled out or opened, the frame I] tilts and the dogs 3 cometo a position in which, should the slides or any of them be at such time raised, their rear ends will drop down against the front edge of the shoulder 06', as shownin Fig. 3,and prevent the closing of the drawer and the restoring of the frame II to its vertical position, and hence any attempt to raise the slides when the drawer is open for the purpose of disclosing the sale at the apertures 'l, U, V, \V, would be frustrated, since the slides would not remain elevated and the dogs y would prevent the registering wheels from being moved forward to the racks M by the closing of the cash drawer.

After the proprietorhas, at the close of day or anyother period, examined the registering wheels through the apertures a, Z), c, d and e, he may return said wheels to zero by means of the slides I, J, K, L, which will then be used to rotate the wheels until the ciphers thereon appear opposite to said apertures.
