CASH-REGISTERING MACHINE.

,SPECIFICATION forming part of Letters Patent No. 504,409, dated September 5, 1893.

Application filed March 29, 1893. Serial No. L1458,13@ (No model.)

To all whom, it may concern:

Be it known that I, FORTUNE L. BAILEY, a citizen ofthe United States, residing at Northampton, in the county of Hampshire and State of Massachusetts, have invented new and useful Improvements in Cash-Registering Machines, of which the following is a specification.

The objects of this invention are to provide improved drawer locking devices, and a safety device in relation thereto, for preventing the opening of a drawer except through means of the key; improved devices for guiding the drawer evenly and easily; improved registeroperating devices whereby each keylever may move the register its proper proportionate distance to accord with the amount indicated by the key;-and there is comprised as a part of, or in conjunction with, the registeroperating device improved means for preventing the register wheel from ruiming away from its actuating part,that is moving by momentum a distance in excess of that intended, as might occur on the somewhat violent operation of any of the key-levers. And there is, furthermore, comprised in conjunction with the register operating mechanism means whereby all of the keys, except the one being operated, are locked against movement. And there is, furthermore, an improved construction of device to hold all of the keys locked when the drawer has been opened,whereby it becomes impossible to operate any key unless the drawer is closed.

To these ends the invention consists in constructions and combinations of parts all substantially as will hereinafter fully appear and be set forth in the claims.

Reference is to be had tothe accompanying drawings in which- Figure l is a sectional elevation of a cash registering machine of the type known as a combined detail adder and total adder, all of the various features of improvement being here more or less clearly shown or indicated. Said figure also comprises, as a projection at the right, a face view of a part of the total adding mechanism. Fie'. 2 is a plan view of the principal parts, as seen above the base or wheels, and their supports being also removed, as they constitute no part of thls 1nvention. Fig is a perspective view of one of the cam-slotted arms and its rocking support,and as detached therefrom the rear end of the key-lever. Fig. 4t isa plan view below the base or table showing the cash-drawer thereunder, and the guide therefor, andthe safety plate for the drawer-lock; and Fig. 5 is a vertical cross section taken on the hne 5 5, Fig. 4., as seen looking forwardly. Fig. 6 is a sectional elevation on the line 6-6, Fig. 2, this view involving a modification ofthe form of cam-slotted rocking members, to be hereinafter referred to while Figs. 7 and 8 are enlarged face and perspective views of the latter.

In the drawings, A represents the set 0f key-levers mounted upon the horizontal shaft, a, Which is supported by the framing, B, the latter being screwed or otherwise secured to the base or table, C, below which the drawer, D, slides in suitable housing therefor. i

Between the rear portions of the framing there is, horizontally extended, and ata short distance above the table, C, the horizontal shaft, Z), on which a series of arms, E, are fulcrum-supported, all of the arms having their bottoms a short distance below the shaft, b, rigidly connected upon the common rockingbar, d, the rocking movement being imparted to the latter by one of the arms, E, which incidentally imparts rocking movements to all of the rest of the arms. Each of the arms, E, has a cam-groove, f, the widths of the various arms and the cam-grooves, respectively therein, bein g graded in regularly increasing pitch so that each successive arm may,-onthe given and uniform arc-play of the stud, g, of the key-lever, respectively therefor within its cam-groove,-have a regularly increased degree of swinging movement, and to consequently impart the corresponding degree of rocking movement to the common bar, d. In both Figs. land 2 it will be noted that the said arms, E, are widened as just above eX- plained.

G represents a ratchet-Wheel which is to be regarded as comprised in, or as an adjunct to, the total adding registering mechanism. The said rocking-bar, d, has at its one end the IOO upwardly extended pawl-carrying arm which l is adapted to swing forwardly and rearwardly as the bar rocks. The pawl, i, is pivotally connected upon the upper end of said arm, h, its tooth taking into the aforesaid ratchetwheel, G, the spring, j, holding it to its ratchet-tooth engagement at all times whether the pawl is moved forwardly to drive, or is being retracted to take a new tooth. Another spring, lo, having one end secured to the arm, h, and its other t0 a suitable fixed part of the frame insures the forward driving movement of the pawl-carrying arm and pawl when the key has been depressed and released, this spring serving to reswing the bar, d, and the several arms, E, back to normal position.

The ratchet-wheel is movable concurrently with the bevel gear-wheel, m, which meshes into the bevel gear, n, of the total adding registering mechanism which is indicated generally by the letter, M, the same comprising several register wheels or disks, 1 2, 3 and 4, the amounts registered by one being, on its complete rotation, accumulated into the next higher, as well known,-this class of registers constituting no part of this invention and a very particular description thereof is not deemed expedient. In fact, and manifestly, other descriptions of cash registers may be substituted for the one indicated.

As an example of a machine equipped with the devices described, we will assume that the rst one of the key-levers will cause, by the impingement of its stud, g, against the wall of the arm, E, such a swinging of that arm, a rocking of the bar, d, and swinging of the arm, h, and pawl, t', rearwardly as to cause the latter to pass back over one whole tooth ofthe ratchet-wheel; the next key-lever insuring the retraction of the pawl twice as far, the third three times as far, and so on, the last key,-being for instance the fifty-cent key,-causing the retraction to the extent of ten of the teeth. Therefore, of course, the depression and release of each key will, through the novel mechanism described, result in the rotational movement of the ratchet-wheel, G, and operation of the register in the extent desired and proportionately correspondingto the amount assumed to be represent-ed by the keys. It will be noticed that each of the arms has the arc-formed slot, o, which is concentric with the center of swinging movement of the arm these slots merging into the aforesaid cam slots, f. As each key is depressed, (its stud, g, rising in, and exerting a forcing action on the border of, the slot of the respective arm therefor, and the common bar, d, with all the other arms, swinging inthe extent determined by the depressed key) the upper borders of the slots, o, for all of the other arms, E, of the series, ride over the studs of the non-depressed keys and serve as very effectual locks against the depression of any one or more of the non-depressed keys. The upper ends of the slots,f, form the means of limitation for the swinging movements of the key-levers.

In carrying out this invention with respect to the register operating mechanism, the graded set of cam-slotted arms, E, have footlugs, (Z2, by which they are screwed tothe bar, d. Y It is, of course, to be understood that the arms graded for the greater swinging movements have the lengths of their slots, o, correspondingly increased so that as the bar is swung by any one of the key-levers, all of the other arms, swinging in consonance therewith, will have free play by their slots over the studs of the passive key-levers.

The case or housing, .l for the drawer, D, under the table, C, has the upper and lower horizontal parallel strips, S, S, extending from front to rear between the sides. The drawer has, at its rear, the ianged roller, t, which is journaled for rotation in a vertical plane coincident with the direction of movement of the drawer. And this roller is of such diameter as to have the flanges at its upper and lower edges overlie the opposite sides of the said strips, s, s, the lower strip supporting the weight of the drawer through the roller. As seen more especially in Figs. 4 and 5, the rear wall of the drawer,which may form the boundary of one of the bill-compartments, is cut out, as indicated at a, and the metallic carrier, o, for the roller, is let within the drawer through this recess, u. This rollercarrier consists of a metallic strip or casting which is of U-form having the laterally turned extremities, e2, r2, which are screwed to the outer side of the rear wall of the drawer. This part, e, in addition to serving as the journal support for the roller also serves to reinforce the recessed back wall of the drawer.

In the middle of the drawer, at its top, is the horizontal rectan gularly recessed plate, w, the rear boundary, w?, of the recess constituting the abut-ment which is engaged by the arm, of the rocker-plate, y. The rockerplate extends under and is common to all of the key-levers, and is normally in the position seen in the full lines in Fig. 1,that is when no key is depressed,-but as a key is depressed the rocker-plate is swung, as indicated in the dotted lines in Fig. l, carrying the end of the arm, out of engagement with the catch-abutment of the drawer. The arm, plays through the aperture, m2, therefor, in the table, C, of the machine.

P represents a flat, rectangular, metallic plate pivotally supported within the aforesaid apertured plate, w, and having the tendency to be self-leveling so as to lie horizontally in the plane of the plate, tu; but it will be apparent (see Fig. l) that so long as the key is in its normal position, the drawer being closed and the arm, :15, is in its indicated locking engagement with the abutment edge, 102, the said plate, P, will be tilted into the forwardly and upwardly inclined position shown in Fig. l. It will therefore be appar- IOO IIO

ent that a person cannot, by running a thin blade or other thin article through the crack, if any there be, at the upper edge of the drawer, reach the locking arm, or, to force it from its drawer-locking engagement.

In'the operation of the register actuating mechanism, comprising the ratchet-wheel, Gr, and the pawl-carrying-arm, h, with the driving spring, 7c, it will be understood, that as any one of the key-levers is depressed the pawl-carrier moves rearwardly enabling the pawl to take as many new teeth as properly corresponds to the amount represented by that key-lever which causes the retractile movement of the pawl-carrying-arm; and that the driving movement is imparted to the ratchet-wheel after the key-lever has been fully depressed and released by the spring, 7a, which causes the pawl-carrying arm to come to bearing against the edge of the ratchet- Y wheel; and it will also be perceived that by reason of the one or more teeth, h2,'-formed at the forward edge of the pawl-carryingarm,-coming to engagement with the ratchetwheel just as said arm completes its forward driving movement there can be no over-running of the ratchet-wheel by momentum, to result in over-registration; Of course in lieu of the driving spring, 7c, for effecting the return of the pawl-carrying-arm 7L, and, as one therewith the series of swinging arms, c, and the key-levers, the return movements of these parts might be positively imparted through the key-lever by the hand.

In the drawings, Figs. 6, 7, and 3, the swinging camslotted arms, E', are of somewhat different form, they being so fulcrumed that the cam-slots, f thereof are below the shaft or support-rod, b. The slots,f, of these arms are open to the bottom, while the common uniting bar, d, is secured to all of the arms above the fulcrum, the paWl-carrying-arm, h, being connected to the said bar substantially as in the other arrangement indicated in Figs. l and 3. The part, 02, serves in this form of the arm as the key-lock substantially the same as the upper border of the slot, o,in the form of the members shown in Fig. 3.

In the cash-registering machine here illustrated, the bar, R,-which is mounted on the arms, R2, which are fulcrumed on the shaft, a, on which the key-levers are mountedfranges across all of the keylevers and is swung upwardly as any key-lever is operated; and of course when this bar is in its normal position and locked against movement none of the key-levers may be operated.

T indicates a plate capable of a fore-andaft sliding movement under the key-levers, this part being constrained for its movement by the Shanks of the screws, a, passing through the slots, a4, and into suitable stationary supporting parts of the machine. This plate has the upright, b3, with the hooked extremity b4; and the spring, d2, exerts the action upon the said plate, T, to forwardly draw it so that the hook, b4, will engage the aforesaid bar, R, and therefore lock all of the keys against movement. The said plate, T, has the depending stud, c3, which passes downwardly through a slot, c, in the base, C, of the machine to he rearwardly moved by the drawer, D, as the latter is closed, so that always when the drawer is closed the hooked upright, b3, b4, is out of engagement with the bar, R.

A person,having made the proper registration by the depression of one or more keys, and, having` through well known mechanism released the drawercatch, permitting the drawer to open, manifestly, after the keys and bar,R, then return to their normal positions, unless the drawer is forced closed,the hooked upright, h3, will be moved into its bar-engaging position and another registration may not be made. If it is desired to restrain this last described device from its automatic operation, so that, at pleasure, registrations may be successively made even while the drawer remains open, the proprietor, or authorized person having access to the interior of the cabinet, may upwardly draw the vertical rod, f3, on which is the cam incline, f4, so that said incline, in its impingement against the pin, b5, will rearwardly force the hooked bar and its plate, T, and restrain these parts against sliding movements so long as the rod,f3, remains in its elevated position.
