CASH-CARRIER.

SPECIFICATION forming part of Letters Patent No. 416,924, dated December 10,1889.

Application filed May 21, 1887. Serial No. 238,962. (No model.)

To all whom it may concern:

Be it known that I, THOMAS M. KENNEY, of Cambridge, county of Middlesex, State of Massachusetts, haveinvented an Improvement in Cash-Carriers, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invention relates to a cash-carrier of that class in which the carrier or receptacle is propelled along a track consisting of a stretched Wire or cord, and the invention 0011- sists, mainly, in the novel construction of the motor for propelling the'carrier.

The motor consists, essentially, of a sliding device normally engaged with the carrier when at the station, and a hand-actuated spring connected with the said slide-bar in such manner that when the spring is strained it presses the bar against the carrier. The bar is restrained from moving when thus pressed upon by means of a locking device, which is disengaged and releases the carrier when the spring is sufficiently strained to 2 5' propel the carrier to the remote station.

Figure 1 is a side elevation of cash-carrier apparatus embodying this invention, showing the devices, in full lines, in the position occupied when the carrier is at the station and while the actuating-spring is being strained, and in dotted lines in the position occupied at the moment that the carrier is released; and Fig. 2 a front elevation of the apparatus at the station. 1

3 5 The track ais shown as consisting of a wire or cord extending from one to the other of the points or stations between which the cash or other material is to be conveyed, the said track being fastened at its ends to any con- 0 venient support. At the stations at the en ds of the track a the latter passes through a bracket b, which may be supported from the ceiling or any other suitable support, being shown as screwed upon the end of the rod 19. The

5 said bracket b is provided with a guide b for the sliding device or propelling-bar c, which is free to move in said guide in a direction parallel with the track a, and is provided at its forward end with a carrier-engaging portion 0, (shown as a fork,) that engages a portion of the frame 61 of the carrier, said frame to send it into the station at the other end of (Z being hung from grooved Wheels (1, that run on the track a, and having at its ends downwardly-projecting arms d that co-operate with the propelling mechanism at the stations.

The box or receptacle d for the cash or other articles or material to be conveyed is shown as a cylinder closed at its lower end,

adapted to be connected by a suitable fast- 6 ening with a cap-plate (1 preferably pivoted to the frame d, so that the said receptacle is free to swing on the said frame d. The fastening of the receptacle (.1 to the capplate or head-piece d is shown in this instance as effected by means of pins or projections d on the said receptacle that engage with curved arms d on the head-piece 01 so that by placing the pins d above the ends of said arms (1 and then turning the receptacle (1? about quarter around said receptacle will 7 be held securely up to the headpiece d but it is obvious that any other suitable catch or fastening might be employed to hold the receptacle d on the carrier'frame d. p

The arms d at the end of the carrier-frame are provided with inclined striking faces 01' cams 01 which, when the carrier comes into the station, engage a locking device e, pivoted at e on the bracket 1) and normally held by a spring e against a stop (2 in position to engage the arm d and prevent the carrier from moving away from the station, as shown in Fig. 1, although the said locking device is turned by the engagement of the inclined faces or cams to permitthe arm d to pass by it as the carrier comes into the station.

For the purpose of propelling the carrier away from the station with a force sufficient the track, the propelling slide-bar c is engaged by a spring f, provided with means for straining it so as to press the bar 0 against the carrier in the direction to propel the latter along, the track. The carrier cannot, however, move under the action of this pressure until disengaged from the locking device 2, which disengagement takes place when the spring is strained the proper amount to give the desired propelling impulse. In order to properly strain the spring and disengage the carrier at the proper moment,the said spring is ICO connected with an actuating-band f, (shown as connected with the drum or pulley 9,) having connected with it a second drum or pulley g, to which is attached an actuating-cord g, provided with asuitable handle g accessible to the operator. Thus by pulling down the handle 9 the pulleys g g are turned and the bandf wound upon the latter, thus straining the springf.

The locking device 6 is provided with an arm 6 at the opposite side of its pivot from the part that engages the arm 01 of the carrier, which arm e is provided with pins or projections 6 embracing the band j", which til the carrier returns, when the latter will engage the forward end of the said slide-bar and move the latter back to its normal position, (shown in Fig.1) simply unwinding the band f and winding up the cord g Without straining the spring f.

It is obvious that the band f might itself extend over the pulley and be provided with the actuating-handle instead of using a separate actuating-cord 9 but by using the two pulleys, as shown, any desired relation between the force of the springf and the force required to be applied to the handle g to strain it may be attained, and thus a very stiff quickly-acting spring may be used Without requiring too great force to be applied by the operator to the handle g In many cases the track a will be arranged in an inclined position,in which case the propelling device at the lower end will have sufficient force to propel the carrier up the incline, and it may be returned by aweaker propelling device, or by gravity alone it the incline is suificient, in which latter case no propelling device will be required at the higher end of the track.

I claim 1. The combination of" the track a and bracket Z), located near one end thereof, the propelling slide-bar longitudinally movable in a guide in said bracket, and the actuatingpulley and locking device pivotally supported in said bracket below said slide-bar, a band connected with said pulley and with a spring, which spring is connected with said slide-bar, and a tripping projection on said band, said locking device having a shoulder at the front of the pulley to engage with the carrier, and an arm at the rear of the pulleyto engage the said projection on the band, substantially as and for the purpose described.

2. The combination, with the locking device e, of the propelling-slide c and its actuating-spring f, and the band f and cord g and connected pulleys g g, to operate substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
