UNITED STATES CHARLES FISHER, OF MANITOYVOO, VISGONSIN,

ASSalGliUlt TO THE INTER- NATIONAL STORE SERVICE COMPANY.

STORE-SERVICE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 314,814, dated March 31, 1885.

Application filed December 29, 1884. (No model.)

To all whom it may concern Be it known that I, CHARLES FISHER, of Manitowoc, in the county of Manitowoc and State ofWisconsin, have invented certain new and useful Improvements in Store-Service Systems; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to storeservice systems, the object being to provide an improved receiver of novel construction for use in connection with systems employing rolling carriers.

The invention consists in a receiver for storeservice systems adapted to be automatically raised and lowered by the movement of the carriers.

The invention further consists in the various appliances, hereinafter fully described, when combined with the receiver of a storeservice system.

Figure 1 is a side elevation of a portion of the track and guideway of a store-service system with my improved receiver and its operatin g mechanism applied thereto. Fig. 2 illus trates a detail.

A represents the track or strip upon which the carriers travel, and A a short guard-strip arranged above the track A and secured th ereto by rods a.

B represents the strip or way, to which the guard-stripAissecuredby connecting-stripsb.

0 represents the carrier-seat of the receiver, formed on its upper side with a beveled stop, a, and secured loosely by a spanning strip, 0, upon the way B.

D represents a curved spring, which is secured at its lower end by a spanning strip, (1,

loosely upon the way B. This spring D eX- The seat 0 is provided with an upwardlyprojecting eye-rod, F, to which is secured an elastic cord, G, formed with a knot, g.

H represents a springsupport, rigidly secured at its upper end to the inner side of the way B. This support H extends downwardly below the seat 0 when the latter is in the po- 1 sition shown by the full lines of Fig. 1, and is inwardly bent at its lower end to engage the lower edge of the seat 0, as shown. This spring is also formed with a bracket-like extension, h, which projects inwardly over the stop 0 of the seat (when the latter is raised) in position to be struck by the carrier I after the latter has rolled onto the seat.

The inner side of the way B is recessed adjacent to the spring-support H, to enable the latter, when struck by the carrier, to be forced out of engagement with the seat 0, as shown 7 in dotted lines, Fig. 1.

J represents a rod pivoted to a bracket, j, projecting from the strip A, adjacent to the way 13. The inner end of the rod J is bent downwardly and slightly curved, to extend through an opening formed inthe strip A, and is provided at its free end with a short cross-bar, J upon-which is secured an elastic bumper, J

The elastic cord G extends through an opening in the strip A, and also through an opening in the arm J, the knot 9 being below the arm J, and serving to hold said arm in ele vated position when the receiver is raised.

L represents an elastic bumper, which serves as a stop to limit the upward movement of the receiver.

The operation of the improvement thus described is as follows: The carrier will readily roll from the track A onto the seat 0, and, 0 striking the bracket h of the spring-support H, will release the carriage, which will immediately descend. The descent will release the arm (2 from its engagement with the shoulder E, and said arm will at once assume the posi- 5 tion shown in the dotted lines of Fig. 1 to secure the carrier upon the seat. The descent of the seat has the further effect of al lowing the guard-arm J to drop into the position shown by the dotted lines, Fig. 1, to hold back any carrier that would otherwise roll oil after the seat has begun its descent. The

elastic cord G (whose upper end, it will be understood, is suitably secured above the strip A) will draw the seat back to its raised position as soon as its load is removed, thus reengaging the spring-support H with the seat 0, and by means of the knot g elevating the guard-arm J to allow the waiting carrier to roll onto the seat.

The spring-support D serves as a brake to prevent undue speed in the descent of the receiver by reason of its frictional contact with the Way B.

I do not limit myself to the use of an elastic cord for raising the seat, as a spiral spring or other elastic suspensory might be employed in lieu thereof; nor do I limit myself to the other details of form and construction, but reserve to myself the right to make all such minor changes and modifications as may p roperly fall within the scope of my invention.

Having fully described 1nyinvention,whatl claim as new, and desire to secure by Letters Patent, is-

l. The combination, with the receiver of a store-service system, of a spring-catch for supporting the receiver in raised position, said catch being adapted to be struck by the carrier to automatically release the receiver, substantially as set forth.

2. The combination, with the receiver, of a spring-catch for supporting the receiver in raised position, and adapted to automatically release the receiver by contact with the carrier, and a spring-brake provided at its free end with an arm to support the carrier upon the seat, substantially as set forth.

3. The combination, with the shouldered end of the track-strip, of the seat and its brakespring, whose free end is provided with a guardarm, which engages the shouldered strip, substantially as set forth.

4. The combination, With the receiver-seat and its beveled stop, of the spring-support provided with an inwardly-proj ecting bracket and a shoulder, as described, the combined spring-brake and guard, and the elastic suspensory, substantially as set forth.

5. The combination, with the receiver-seat and its suspensory formed with a knot or stop, of a pivoted'guardarm adapted to be automatically raised and lowered, substantially as set forth.

6. The combination, with the receiver, of a pivoted guard supported above the track and adapted to be automatically raised and lowered by the elevating-cord of the receiver, substantially as set forth.

7. The combination, with the single guide strip or way, recessed as described, of the carrier-seat andits suspensory formed with aknot or stop, and its beveled stop, the spring-support formed with a shoulder to engage the seat, and with a bracket projection adapted to be struck by the carrier, the curved spring forming a combined brake and guard, and the pivoted guard-arm adapted to be automatically raised and lowered, and provided with a bumper at its free end, substantially as set forth.

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

CHARLES FISHER.
