STORE-SERVICE APPARATUS.

SPECIFICATION forming part of Letters Patent N 0. 469,014, dated February 16, 1892. Application filed March 26, 1891- Serial No. 386,495. (No model.)

To all whom it may concern.-

Be it known that I, ALFRED J. GILLESPIE, a citizen of the United States, residing at Atlantic, Iowa, have invented certain new and useful Improvements in Store-Service Apparatus, of which the following is a specification. My invention relates to certain improvements in package and cash carriers, and particularly to an improved form of back-stop [O which is provided to stop the cars as they approach the elevator-well.

I 5 tracks are employed, arranged one above the other in the same vertical plane, and which are provided with elevators for raising the cars from the counter and dispatching them upon the upper track to a cashiers desk or wrapping-table, from whence they are re turned on the lower track and descend upon the elevator to the counter. In this system no turn-outs are employed, but free tracksections are used to bridge the elevator-well to permit the passage of a car when the elevator is not in use, said sections being raised by the elevator on its upward movement and deposited again on its downward movement.

In this system, also, a cable or cord is em- 0 ployed to raise theelevator; and afeature of my improvement consists in the employment of this elevator-cable to operate the backstops. The track rails or Ways are composed of flanged metal bars, and I perforate the 3 5 webs of these bars for the passage of the engaging end of the back-stop, said perforation forming a guide and way for the stop and causing its certain and effective action to stop the car.

In the drawings, Figure l is a side elevation of a section of the upper and lower tracks at a station with a basket or carrier on the upper track. Fig. 2 is a plan View of the same below the line 2 2 of Fig. 1, and Fig. 3 is a sectional elevation looking to the left of line 3 3 of Fig. 2.

In the drawings,

A represents the upper track, having the swinging track-section A, andB the lower track, having a movable section 13.

C is a supplemental track-section adapted to bridge the gap when the elevator is below the lower track rail. The track-rails are flanged metal bars, in this instance of U form, and with their webs vertically disposed. The track-rail A at a suitable distance from the elevator has its web slotted longitudinally,

as shown at a, and-through this aperture the back-stop works. This back-stop consists in the form shown in the drawings of a sleeve C, having a dog a thereon, which is adapted to enter the slot at in the track-rail. The sleeve is carried by one member D of a bellcrank lever loosely or pivotally connected to v the side of the rail. A spring E surrounds the member D, one end of the spring form-. ing a yielding seat for the sleeve, the other end of the spring being seated against a projecting shoulder cl of the member D. A keeper F limits the outward movement of the free end of themember D. The member D of the bell crank is connected at its outer end to a link G, and said end is normally retracted by a spring H, made fast at one end to the well-frame I. The opposite end of the link G is connected to a bell-crank J, pivoted on frame I, and to the other 'mem ber of the bell-orank is secured one end of the operating-cable K, which is passed over a suspended sheave 7c, and thence conducted around a sheave Z on the elevator-car L, and thence up around. the guiding-sheaves M M, from the latter of which it depends within reach of the attendant. The lower rail is provided with a back-stop identical in construction with that just described, but located on the opposite side of the well of the elevator. The bell-crank of the lower back-stop is connected with the bell-crank J of the upper by means of the link N, and hence a pull on the elevator-cable operates both of the backstops simultaneously.

It is evident from the foregoing that so long as the elevator-cable is under tension the back-stops are held in position to arrest the cars on the tracksleading to the well, and it is also evident that the cable cannot be made effective to lift the elevator-car until the back-stops are thrown into operative position. Obviously this back-stop can be used in a cash-carrier system having a single trackrail instead of the two track-rails shown,and

in this case, as there would be only one backl of its body, of a back-stop device comprising 3 5 stop at each station, the elevator-cable would an operating-lever pivotally mounted at the be adapted to operate but one back-stop. side of the rail, and a dog having a sliding It will be observed that the back-stop serves connection with said lever and adapted by the 5 the purpose of a spring-buffer and that it is vibration thereof to be projected through the guided and controlled in its movement by aperture of the rail into the path of a moving 4o traveling in the slotted way formed in the rail. carrier, substantially as described.
