CASH REGISTER AND INDICATOR.

SPECIFICATION forming part of Letters Patent No. 556,756, dated March 24, 1896.

Application filed November 29, 1892- gerial No. 453,470. (No model.)

To all whom it may concern:

Be it known that 1, JOHN J. LAWRENCE, Jr. a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Cash Registers and Indicators; and I do hereby declare the following to be a full, clear,.

and exact description thereof.

My invention relates to what are commonly termed cash registers or indicators, its object being to construct a simple form of apparatus which is free from the complicated mechanism and multiplication of parts which mark the machines now in use, and which not only increase their cost, but also their liability to get out of order.

.To enable others skilled in the art to make and use my invention, I will describe the same more fully, referring to the accompanying drawings, in which Figure 1 is a sectional side elevation of my improved cash-register. Fig. 2 is a top View of same with the cover removed. Fig. 3 is a top view with the recording apparatus removed and showing the operation of thelevers and drawer. Fig. 4 is a-rear view. Fig. 5 is a section on the line 5 5, Fig. 1, showing the construction of the tilting frame. Fig. 6 is a central sectional side elevation showing the position of the tilting frame with one of the keys depressed. Fig. 7 is an enlarged plan view of the gearing mechanism which operates the registering-dials. Fig. Sis a face view of the dials. Fig. 9 is an enlarged sectional View of the card-releasing device, and Fig. 10 is an enlarged sectional view of the tilting frame and recording mechanism.

Like letters and figures indicate like parts in each of the views.

The box or casing which incloses the meohanism may be formed of wood or metal, as desired, and it consists of the base-plate A, the ends A A the rear plate A and the hinged cover or lid A which is preferably curved to add to the appearance of the apparatus, and by which access is obtained to the working parts of the same. Secured in the ends A A of the box and extending longitudinally thereof is the shaft a, and loosely secured to said shaft is the tilting frame a. tilting frame a consists of the parallel bars a o connected by suitable cross-braces a The saidthe bar a having the steps or gradations Z) I) b 12 &c., formed thereon and beginning at the left-hand end thereof, as viewed from the rear on the section 5 5, as clearly illustrated in Fig. 5. The bar a of the tilting frame a has the steps or gradations B B B &c.,but said bar (t is arranged with the narrowest portion of said bar a opposite to the widest portion of the bar a and vice versa, in order that the operating-levers may only tilt the frame a sufficiently to register the desired amount, as will fully appear in the description of the operation of the register hereinafter set forth. To further provide for the tilting of the frame a to a sufficient degree to operate the gearing mechanism. connected thereto, the said frame is preferably secured to the shaft to in such position that said shaft will pass through said frame at points slightly off a central line passing longitudinally thereof, whereby a greater tilting action can be imparted to said frame. Secured to the shaft (L is the toothed sector 0. To further support said toothed sector 0, it may be formed with an arm (1 secured to the bar a of the tilting frame. The bar a of said tilting frame is provided with the slot (1 adapted to receive a portion of the toothed sector 0. It is apparent that the tilting frame may be constructed in different ways without departing from the spirit of my invention, and that it may be made larger or smaller, according to the size of the machine.

A second tilting frame, 6, is mounted on the shaft a, and, as in the case of the tilting frame a, said frame is-loosely mounted on said shaft, so that it may be tilted independently'of any like movement on the part of the tilting frame a, for the purpose more fully hereinafter set forth. This second tilting frame, 6, is similar in construction to the tilting frame a, but is usually made of shorter length, as it operates to register dollars, while the tilting frame a operates to register cents in the ratio of lives. Accordingly said tilting frame 6 is formed of the bars 6 6 connected by cross-arms e the said bar 6 having the steps or gradations e c 6 &c., and the bar 6 having the steps or gradations E E, &c., all arranged in the same manner as the tilting frame c. There is also a toothed sector f mounted loosely upon the shaft a and secured by the arm f to the frame 0. Further, said frame 6 is mounted on the shaft to on a line slightly off a central line passing longitudinally of said frame, for the purpose hereinbefore set forth.

The toothed sector c is adapted to mesh with a gear-wheel g, mounted loosely on the shaft g, said shaft being journaled in suitable standards erected within the box or casing. In order to turn the shaft g to operate the reg istering mechanism, as hereinafter set forth, said gear-wheel g is provided with a pawl and ratchet g adapted to engage, the ratchetwheel g, secured to the said shaft 9, whereby upon the revolution of said gear-wheel gin one direction the pawl will turn the ratchetwheel g" and the shaft g, but upon the revolution of said gear-wheel g in an opposite direetion the said pawl will pass over the teeth of said ratchet wheel without turning the shaft g. An additional ratchet-wheel, g, is secured to the end of the shaft g with the ratchet-and-pawl device g", whereby said shaft g is permitted to turn in one direction. A bevel-pinion h on said shaft g meshes with a bevel-pinion 7b on the shaft h, which is journaled in the standard 72/3, and the plate h", carrying the registering-dials II II H 011 the outer end of the shaft 7L2, adjacent to the inner face of the plate 7U, is secured the gearwheel '2', adapted to mesh with a gear-wheel i, mounted loosely on the stud T projecting between the standards h and h". This gearwhecl '11 is provided with a rigid pawl or finger i, which is adapted upon each complete revolution of the gear-wheel. t" to engage with a gear-wheelj, rigidly secured to a shaft j, and impart a partial revolution thereto. The shaft j is journaled in the plate 71; and in the standard 7:. Back of the gear-wheelj is the ratchet-wheel 75, secured to the shaft j. A ratchet 70' engages with said ratchet-wheel 7e and is held in engagement therewith by means of the spring-arm 70*, whereby said ratchetwheel is only permitted to move in one direction. On the inner end of the shaft j is the bevel-pinion 1, adapted to mesh with a bevelpinion Z, secured to the shaft Z said shaft being journaled in suitable bearings in the standards and 7 A similar bevel-pinion, m, secured to the said shaft 1 meshes with a bevel-pinion in on the shaft 171*, said shaft being journaled in the standard it and the plate 71 Rigidly secured to the shaft m is the wheel m, provided with the rigid linger m7, which is adapted upon. each complete revolution of the wheel m" to impart a partial revolution to the gear-wheel a secured to the shaft n jourualed in the standard 72, and plate 75. To prevent any backward movement on the part ofsaid gear-wheel n andthe shaft 11, a ratchetwheel a is secured to said shaft, with which the ratchet 22 engages, held .in position by the springarm it. Finally a gear-wheel 0 on the shaft Z meshes with the toothed sector f on the tilting frame e. Said gear-wheel 0 is provided with the pawl and ratchet 0, adapted to engage the ratchet-wheel o secured to the shaft 1*. This completes a description gen erally of the gearing mechanism operated by the tilting frame and throughwhieh the registering on the dials is accomplished. In the description of the operation of the machine, hereinafter set forth, the purpose of such gearing mechanism will be clearly apparent when taken with the other parts of the apparatus.

The dials II II II have been referred to and said dials may be constructed of any suitable material and the numbering on the faces of said dials will correspond to the number of keys and the registering capacity of the device. The shafts 71. it may be termed the index-shafts, as it is to the ends of said shafts that the index-fingers l 2 3 are secured. As I have illustrated my invention in connection with a register having three dials, the first dial, II, is for registering cents and is divided into twenty parts, numbered 0 15 20, &c., up to 95; the dial II is for registering dollars and is numbered 0 I 9 3 i o, &c., up to 19; and the dial H is also arranged to register dollars, but it may more properly be termed the adding-dial, as it sums up the amounts registered by the dials II and II. As the dial II is capable of registering up to twenty dollars, when that amount has been registered on said dial the index-linger on the dial II will move from 0 to 20, and aceordingly said dial is marked 0 20 i0 Si), &c., up to 38.0.

In order to operate the tilting frames a and c, lovers 1) 12 M)" r", &c., and levers I 1 P, &c., are employedrespectively. The said levers 1) p p p, &c., are arranged on the shaft 1 journaled in the ends A A of the box or casing. The number of the lovers 1) F p 1'), &c., and I P P, &e., corresponds to the number of the steps or gradations I) U U", &c.,

i *3 15*, &c., and c" c c, &c., E E E", &c., on the tilting frames at and e, respectively, and each lever engages with two of said steps. Forinstance, the lever 1) engages with the steps I) B, the lever 17 with the steps b and B and so on throughout the series, and likewise the lever I with the steps (3" It, and so on in the same manner. In order to hold each lever in position, so that it will always engage with its corresponding steps or gradations on the tilting frames, guides r are provided for each lover. The outer ends of said levers g) p 1')" p", dsc, are provided with suitable keys marked 5 1015 20 25, &e., while the lovers 1 I I &c., are provided with similar keys marked $2 $3 be.

The drawer s for containing the cash fits in the lower part of the box or casin and is adapted to slide to and fro in suitable guides. Back of said drawer sis the carriages, which is adapted to exert sufficient force against the back of said drawer to open the same. This carriage 3' consists of the bar 5* normally in contact with the back of the drawer, the

IIO

guid e-bars s resting on the base A of the box or casing, the rack-bars s secured to said guide-bars, the end pieces 8 and the standards s, which support the locking-bar 8 whose particular function will more fully hereinafter appear. In order to operate the carriage s so that sufficient force will be imparted to it to open the drawer, a shaft 25 is journaled in suitable standards If in the rear of the box or casing, said shaft having mounted on the ends thereof the toothed wheels 2?, adapted to mesh with the rack bars s on the carriage s. A coiled spring i is wound about the said shaft 15, said spring being secured at one end to the said shaft and at the other end to a fixed support, such as the bar 25 This spring i must be of sufficient strength to drive forward the carriage s with force enough to open the drawer, and as said drawer may often contain a great deal of coin it may be necessary from time to time to increase the impelling force of said carriage. Accordingly the shaft 75 may be made to extend beyond the end wall A of the box or casing, where it can be provided with a key or handle for winding up the spring 15 to obtain the necessary increase of power to open the drawer.

As hereinbefore mentioned, the carriage 3 supports the locking-bar 8 said locking-bar acting to lock the remaining levers p 19 133, &c., and P P P, &c., after one of said levers has been operated in registering the amount of apurchase, whereby only one lever can be operated at a time and no opportunity is given to register falsely. s is supported on the carriage s at an inclination in order to correspond with the inclined ends of the levers p 19 11 &c., and P P P, &c., said levers being provided with inclined ends in order to permit of the advance of the locking-bar with the carriage, for otherwise, if said levers were formed with square ends, it would be necessary to provide for the raising of the inner ends of said levers to a greater height to give the required clearance, and this could only be accomplished by increasing the length of said levers and the size of the machine. The inner ends of the levers p 13 13 &c., and P P P, &c., rest upon the su pporting-bar i In order to retain the drawers normally in its closed position, a rocking frame a is mounted 011 the shaft (1, said rocking frame consisting of the bars a U2, connected by the rockers 2L3, through which the shaft g passes. A dog or detent o is secured to the rocking frame a and the shaft q, said dog or detent extending rearwardlytherefrom and engaging with the back wall of the drawers, whereby the impelling force of the carriage s is counteracted and the drawer is held in its closed position until the dog or detent o is released upon the depression of one of the key-levers p 13 13 &c., and P P P &c., as will more fully hereinafter appear.

This locking-bar The carriage s carries a suitable striker w, which is adapted upon the advance of the carriage to impinge the knob 10 of a suitable gong or bell 10 secured in any convenient manner within the box or casing.

The rear portion of the box or casing is elevated above the main portion in order to provide for the exposing of the cards containing the amount of the last purchase, which is generally one of the functions performed by these cash-registers. Horizontal bars a: are arranged the one above the other, said bars being supported by the standards A of the box or casing, and having formed therein at regular intervals a series of openings 00, the position of the openings in the upper bar coinciding with those of the lower bar. Rods y g 3 &c., are adapted to enter the openings 00 and move readily up and down therein, the number of said rods corresponding to the number of the key-levers pp p &c., and P P P &c., and the lower end of each rod 3 1 g &c., is arranged to be engaged by the inner end of the corresponding key-lever, whereby upon the elevation of the inner end of one of said levers the corresponding rod will likewise be elevated. The upper end of each rod y g 850., carries a card or check, of any suitable material, bearing a number on it corresponding to the number on the key of the lever which operates said rod.

As hereinbefore mentioned, in cash-registers of this class it is customary to expose to view a card or check bearing the amount of the last purchase, and this card or check remains in full view until another purchase is made, when, upon striking another key to register the amount, the first-mentioned card or check drops out of sight and a different card or check is thrown into full view, havin g a different amount thereon. In this manner the amount of each purchase is always exposed to the purchaser, and the amount of the last purchase is always known. In order, therefore, to provide for the lowering of the exposed card or check upon the elevating of another which indicates the amount of the next purchase, a tilting frame .2 is journaled in the standards A said frame comprising the rods 2- .2 joined at their ends by the crosspieces The tilting frame .2 extends above the upper one of the bars in and is normally slightly tilted toward said bars :0, the amount of the tilting action of said frame being regulated by the stops or pins .2 on the standards A. The rods y 1 1 &c., are formed with the inclined lugs which project toward the tilting frame ,2, so that upon the elevation of the rods y &c., through the levers p 19 P3, g and P P P, &c., the inclined faces of said lugs will come in contact with the up per rod, 22, of the tilting frame .2 and throw back said frame until said lugs pass above said rod .2 when the tilting frame will resume its normal position of inclination. In this manner, with the lugs 2 resting upon the upper rod, rods y y position.

In order to lower the rods 2/1/ 31 &e., said rods are provided with the studs or pins .2, which upon the raising of said rods are adapted to come in contact with the lower rod, .2, of the tilting frame Although the lugs act to tilt the frame .2, yet the pins .2 further insure such a result. This will act to throw back the upper rod, .2 of said frame and disengage said rod from the rods 1 11 31", supported by the lugs whereby said rods 1 '3 y will d rep of their own accord to their original positions. The cards or checks on the rods y 71 1 &c., are arranged to overlap each other when in their lowered position, in order that they may be compactedwithin a smaller space.

The elevated portion of the box or casing is provided on its front and back face with the opening A, which may be covered with glass, and through which the cards or checks when raised are exposed to full view.

llaving described the several parts which comprise my improved cash-register, I will now describe the manner in which they operate in conjunction with each other.

If a purchase amounting to five cents has been made, and it is desired to register that amount, the operator strikes the key5, which acts to lower the outer end of the lever 1) attached thereto and elevate the inner end thereof. The inner end of said lever p", traveling in its corresponding guide r, first comes in contact with the step or gradation U 011 the tilting frame a with sufficient force to tilt forward said tilting frame a until the said lever also comes in contact with the step 13, as shown in Fig. (3, whereupon, the lever 1) being in contact with the steps I) 3' of said tilting frame a on different sides of the shaft (1, said tilting frame is not free to tilt further. The lever 19 is thus arranged to come in contact with the second step, 15, when the tilting frame a has tilted sufficiently to move the index-finger 1. the proper distance over the face of the dial ll, as will presently appear. As the teeth of the sector 0 mesh with the gearwheel it is at once apparent that as said tilting frame tilts forward said sector will impart a partial revolution to said gearwhcel g. The amount of this revolution of the gear-wheel g is predetermined by the distance bet-ween the numbers on the dial II, it being necessary to impart sufficient movement to said gear-wheel to move the indexlinger of the dial ll from O to 5. Accordingly as said gear-wheel revolves the ratchet-wheel g also revolves, together with the shaft 9 and the bevel-pinion 71. Through the bevelpinion 7L and like pinion h on the shaft 71. the index-finger 1 will move from 0 to 5 over the face of the dial ll. At the same time the gear-wheel i on the shaft h imparts a partial revolution to the gear-wheel t" on the stud i Simultaneous with the operation of the regof the tilting frame, the said are supported in their elevated istering mechanism just described, as the in ner end of the key-lever 1) rises the corre sponding rod 7/ in contact therewith is elevated until the inclined lug thereon passes beyond the upper rod, 2' of the tilting frame .2 when the card or check carried thereby and bearing the figure 5 appears in full view at the opening A of the box or casing. In like manner simultaneously with the depression of the key 5 the rocking frame 11 will be tilted forward, thereby releasing the dog or detent r carried by said rocking frame. Upon the release of the said dog or detent u the carriage s, impelled by the spring i will advance, the toothed wheels 1 engaging with the racle bars s" on said carriage and will force out the drawer s. As the carriage s advances, the locking-bar s carried thereby likewise advances and passes over the remaining keylevers p p to, and l l 1, the, so that any attempt to depress another lever while the lever p is depressed is impossible. As the further upward movement of the rear end of said lever is prevented by the said lever being in contact on both sides of the shaft (1 with the steps l1 ll of the tilting frame a, it is thus apparent that said key is locked against any movement until the drawer is closed, and it is impossible to depress it further to register a greater amount than it represents. At the same time as the carriage s advances the striker 1/: comes in contact with the knob uof the gong or bell n" with sufficient force to sound said gong or bell and to indicate that the drawer has been opened. The operator then deposits the coin in the drawer, and having taken therefrom, if necessary, the correct amount of change closes the drawer. As the carriage s recedes and resumes its former position, the locking-bar s releases the keylOVOlSlfljfZi, &c., and l I 1", &c., and peri'nits the inner end of the key-lever to descend to its normal position with relation to the other key-levers. The rod 7 however, which was elevated by the depression of the key 5, remains in its elevated position, the lug .2 thereon having passed above the upper bar, .2 of the tilting frame and acting to support said rod in its elevated position by engaging with said bar .2. In this manner provision is made for exposing to view, even after the lever 1) has resumed its normal position, the card or check bearing the amount of the pnrchase last registered.

If the next purchase amounts to ten cents, the operator depresses the key 10, when the parts operate in the same manner as before, with the exception that the inner end of the lever engaging with the step or gradation Z) will impart a greater tilting action to the tilting frame (1 than that imparted by the lever 2) engaging with the step or gradation. Z), the consequence being that the sector c will impart a greatermovement to the g'Oll'-\Yllf3tl g and it, through the mechanism described, a greater movement to the indexfinger ll whereby said linger will move over the face IIO of the dial II from 5 to 15. The depression of the key 10 will elevate the rod 1 carrying the card or check bearing the amount of the purchase; but as said rod 1 is elevated the pin or stud 2 coming in contact with the lower rod, 2, of the tilting frame ,2 will throw back the upper rod, .2 thereof sufficiently to release the lug .2 on the rod y, previously elevated, from engagement with said upper rod, .2 whereby said rod y descends of its own weight to its normalposition. The lug 5 on the rod 3 however, engages with the upper rod, Z2, and is held in its raised position with the card or check in full View.

If the next purchase amounts to twenty-- five cents, upon depressing the twenty-fivecent key the inner end of the lever 19 will engage with the step or gradation b, whereupon the tilting frame a will tilt sufficiently to cause the in dex-finger 1 to move over the face of the dial II from 15 to 40, while the check or card bearing the amount of the last pur chase drops out of sight and the newly-registered amount appears in its place, as before described. In this manner the amounts from five cents up to one dollar may be registered on the dial H. \Vhen the index-finger 1 has moved over the entire face of the dial H and arrived again at O, the gear-wheel t", which is revolved by the gear-wheel i, will have made one complete revolution, whereupon the rigid finger 2', carried by said gear-wheel 1, will engage with the teeth of the gear-wheelj and impart a partial revolution thereto sufficient to move the index-finger 2 over the face of the dial H from O to 1, thereby indicating that amounts to the sum of one dollar have been registered on the dial H. In the same manner when the index-finger 1 has moved a second time over the face of the dial H, the gear-wheel i will again revolve sufficiently to move the index-finger 2 from 1 to 2 on the dial H to indicate that amounts to the sum of two dollars have been registered on the dial ll. Thus by glancing at the dial H the total amount registered is readily apparent.

I have confined the description of the operation of my improved register thus far to the registering of amounts from five cents up to one dollar; but I will now proceed to describe its operation in the registering of amounts from one dollar up.

As pointed out in the description, the machine is provided with a second tilting frame,

0, similar in construction to the tilting frame a, butmounted loosely on the shaft a, so that it can be operated independently of the tilting frame a". If the amount of the purchase is one dollar, the key carrying the mark of is depressed, whereupon the inner end of the lever P will come in contact with the step or gradation e and operate to tilt said tilting frame 6. to turn the gear-wheel 0 and through the ratchet-wheel 0 the shaft Z Upon the revolution of the shaft Z the bevel-pinion Z, engaging with the bevel-pinion I, will turn the This will cause the sector f shaft j, whereby the gear-wheeljis revolved sufficiently to move the index-finger 2 from 0 to 1 over the face of the dial H. The other parts of the mechanism operate as before, and the rod 1 carrying the card or check bearing the mark will remain exposed to view until it is lowered by the registering of the next purchase. Then the amounts registered on the dials H II have reached a total equal to twenty dollars, the wheel m will have made one complete revolution and the rigid finger m carried thereby will have imparted a sufficient movement to the gearwheel or to move the index-finger 3 over the face of the dial H from O to 20.

By adding more tilting frames, similar in construction and manner of operation to those described, the machine may be made to register sums smaller than five cents or larger than twenty dollars, as may be desired.
