Fig. 9 is a detail view of a modificasplit end q of an arm Q, extending laterally tion of the guide-roller attachment. from said frame. The lower end of this lever A designates the frame of said mechanism, is bifurcated at P and provided with in- 5 from the base A of which the cash-box is wardly-extending pins 1), which enter the cirsuspended. On its front said frame is procumferential groove 0 of said movable colvided with an offset A having a vertical lar. The upper end of said lever is reduced outer wall which affords onebearing for main to form a stud P, which enters a curved slot shaft 13. The inner end of the main spring 7' in a segment-plate R, fixed horizontally 011 I00 C is attached to the shaft, the outer end of a vertical shaft S, with which it turns. The said spring being attached to a fixed crosslower bearing of said shaft ]S in the arm Q.

Its upper bearing is in a fixed lug s of said frame. 011 the upper end of this shaft a crossbar T is fixed at its middle. WVhen one end of this bar strikes an Obstruction, the shaft S and plate R turn in one direction, and by reason of the shape of slot draw on the upper end of lever P and cause the lower end of said lever to throw the locking-collar outward against the outer disk M, as described, and hold it there. In the arrangement shown this action is effected by the striking of the right end of cross-bar T against an obstruction, the cash-carrier moving from right to left. WVhen the locking movable collar is thus in contact with the outer disk M, the pins 19 are also in contact with the outer wall of the peripheral groove of the locking movable collar. The outer wall of slot 7" in plate R being in contact with stud P prevents the said pins from yielding. The disk M will not allow the movable collar 0 to move farther away from said pins. The said locking movable collar and the pulley-shaft are held together by the engagement of pin 0 with the perforated disk N, and as no part can yield the track-wheel shaft and the mechanism for driving it are locked. When the cross-bar T and shaft S are turned in the opposite direction, the locking-collar is shifted, as before described, away from disk M, the shiftinglever P assumes a more nearly vertical position, the pins are withdrawn from the outer wall of the groove in the locking movable collar, and the shaft J and said locking-collar are free to turn. This of course unlocks also the rest of the mechanism.

' The shaft J consists of two sections J J having telescopic end connection, so that the section J, which carries the pinion I, maybe free to move endwise, although the two sections turntogether. WVhen in its inner position the said pinion, as already stated, meshes with gear-wheel F; but when in its outer position the said pinion meshes with a small wheel or pinion I, mounted on a stud I and meshing with gear-wheel G. As the said wheels F and G turn with the same shaft and always inthe same direction, and as, furthermore, the former wheel acts immediately on pinion I, but the latter wheel acts through the intervention of a wheel or pinion I, which reverses the direction of rotation, it follows that by shifting the section J of the shaft J so as to bring the pinion I into the one engagement or the other the cash-carrier will be driven forward or backward, as desired. The said section J is provided with two circumferential grooves j and j outside of frame A and corresponding in arrangement to the two positions of pinion I. A vertically-movable catch U, sliding in guides U and having a curvilinearly-recessed lower end U engages one or the other of these grooves to hold the pinion I in either position of engagement which may be chosen. WVhen the pinion is to be shifted to the other engagement, this catch is drawn up, the section J pushed in ism driven thereby will remain undisturbed.

When the main spring 0 turns the main shaft B in the opposite direction, the pawl (Z engages the ratchet cl, and the wheels are driven to turn the supporting track-wheel K and 4 propel the cash-carrier. A light spring (1 holds said pawl in engagement with said ratchet. I

The winding is effected by means of a cord V, which is wound on a pulley or drum W, the latter being mounted on shaft 13 and provided with a lateral pin 10, which extends through a curved slot 00 in a disk X, having at times a paWl-and-ratchet connection with said shaft. This pin thus protruding through said slot strikes the operative end of the pawl g, which is mounted pivotally on the inner face of said drum, and said pawl (see Fig. '7) is thereby forced into engagement with the ratchet-wheel Y, which is fast on the main shaft 13. A brake-spring :0, bearing against the periphery of disk X, holds it against being turned by the friction of the drum WV until said pin in its circumferential motion reaches the lower end of slot as, when the said drum and disk will turn together. ceases on the cord V, the said drum will be turned back to its former position by a retracting-spring WV, arranged within said drum. The slot 00 allows the backward movement of said drum to be at first independent of the disk X, so that the pin w is removed from the pawl y before the disk X begins to turn. A spring 3 is then free to lift the pawl y out of engagement with the ratchet-wheel Y and hold it so, (see Fig. 6,) as it always tends to do. The cord V passes down through a perforated guide-lip 2', attached to or formed on the base A of frame A. The drum W, disk X, ratchet Y, and parts attached thereto are located between the main frame A and its offset A so as to be protected thereby. The outer end of spring WV is attached to a clampblock WV which has a screw-threaded shank extending through a slot 1; in offset A said When the pull shank being provided with a nut j outside of v the latter. The inner end of said spring is attached to the cylindrical hub 19 of the drum WV by'a stud 9', which enters a slot therein. Annular plates WV WV are arranged as washers on each side of said spring. The lower end of cord V is provided with the usual handle or knob V.

Z designates an arm rigidly attached to grooved guide-wheel Z running on the track.

The operation of the devices having been for further explanation.

already described in detail, there is little need lVhen the carrier is to be started, the cord is pulled, winding the main spring, which at once drives the carrier along under the supporting-wire until the cross-head T strikes a prearranged obstacle, when the track-wheel K is freed and the shaft J looked, as described. The carrier then runs for a time by its own momentum only. When it comes to a halt, therefore, it does so without any sudden jar- In returning the carrier the shaft-section J is shifted, as described, to reverse the direction of its rotation, the cord V is again pulled, and the cash-carrier travels backward in the same way. Of course a receptacle for goods or anything else which may be suspended from frame A may be caused to travel in the same manner and the operation of the mechanism will be identical.

The devices for changing direction of motion, and, perhaps, some other features of my improvements, are applicable to mechanical movements generally. The function of wheel Z is to steady the running of the cash-carrier. The arm Z may be hinged -to the frame A, as shown in Figs. 1 and 9, to allow for turning curves.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

l. The combination, with the driving mechanism, track -wheel shaft, and loose trackwheel, of a cash-carrier for store-service, a pair of fixed disks on the track-wheel shaft, a grooved movable collar on said shaft between said disks, a lever engaging said movable collar to force it backward or forward, the crosshead T, and connections between said lever and the said cross-head, the said track-wheel and movable collar being provided with pins k 0, which engage substantially as set forth.

2. In combination with a shaft and two gearwheels arranged thereon, a pinion on another shaft, arranged to be moved alternately into engagement with. one of said gearwheels and into engagement with a wheel which meshes with the other one of said gear-wheels for the purpose of reversing motion, substantially as set forth.

3. In combination with a shaft section hav ing a pinion I and two grooves thereon and movable endwise, a catch engaging with one or the other of said grooves at will, a pinion or gear wheel I, and a shaft carrying two gear wheels F G, the gear-wheel F meshing directly with pinion I when the latter is in one position, and the gear-wheel G meshing'with pinion I, which pinion meshes with pinion I when the said pinion I is in the other position, substantially as set forth.

4. In combination with the main spring and wheels of cash-carrier mechanism, a driving or main shaft connected to said spring, a drum on said shaft, a disk having a pawl and ratchet for connection with said shaft, a brake holding said disk against turning by the friction of said drum, and a spring which normally holds said pawl out of engagement with said ratchet, but yields to permit such engagement under pressure of a pin extending from said drum through a slot in said disk, substantially as set forth.

5. In combination with a crossbar arranged to strike obstacles at predetermined distances,- a shaft connected to said bar and turned thereby, a slotted plate carried by said shaft, a lever engaging said slotted plate, a track wheel running on a supporting track or wire, a cash-carrier supported thereby, a trackwheel shaft on which said track-wheel is loosely mounted, and devices operated by said lever for simultaneously locking said shaft and freeing said wheel, substantially as set forth.

6. In combination with a lever and attachments for vibrating it automatically, a trackwheel shaft, and a loose supporting trackwheel forming part of cash-ca1'rier-driving mechanism, a locking movable collar movable endwise, backward, and forward on said shaft, a stop which limits its outward play, and projections which cause said track-wheel and movable collar to turn together when the said locking movable collar is in its inner position, the movable collar always turning with said track-wheel shaft, substantially as set forth.

'7. In combination with cash-carrier frame A and track-wheel K, the arm Z and guidewheel Z said guide-wheel being adapted to run on the track behind the track-wheel and the arm Z, and the frame being provided with a joint for convenience in turning curves, substantially as set forth.

In testimony whereof we aflix our signatures in presence of two witnesses.
