ELEVATOR FOR STORE-SERVICE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 431,783, dated July 8, 1890.

Application filed August 16, 1889. Serial No. 321,011. (No model.)

, Track for Store-Service Railways, of which the following is a full, clear, and exact description.

This invention has for its object to provide a means for transferring or switching a carrier from a dispatch-track to a return-track in a store-service railway where the ends of the tracks are in diiferent vertical and horizontal planes, the one track located below the other. To this end a switching-track is employed which is adapted to be moved vertically and also horizontally into position with the end of a dispatch-track or return-track of a store-service railway.

The invention consists in a combined elevator and switch track for store-service rail-I drawings, forming a part of this specification,

in which similar figures of reference indicate.

corresponding parts in all the views.

Figure 1 is a perspective view showing the switch-track in connection with forwarding-v traok of a store-service railway. Fig. 2 is a detail side view, with parts broken away, of one of the pivotal portions of the switchingtrack. Fig. 3 is a view of the upright upon which the switch-track is mounted and of the drum upon which the cord is wound that operates said switch-track, the upright being shown in vertical section and the drmnin elevation. Fig. 4 is a perspective view of the switch-track in connection with the returntrack of a store-service railway. Fig. 5 is a vertical cross-section of the spring-drum for elevating the switch-track, on the line a: 00 of Fig. 3. Fig. 6 is a plan view, partly in horizontal section, on the line y y, Fig. 1; and Fig. 7 is an enlarged detail side View of a portion of the invention as shown in Fig. 1. r

In the construction of store-service railways it occurs that the terminus of a discarrier reaches the terminus of the dispatchtrack to transfer it to the return-track. To accomplish this, I have provided a switching track and elevator which will receive the carrier from the dispatch-track and may be moved with it into position with the return.- track to transfer the carrier thereto.

In carrying out this invention a preferably hollow upright or post 1 is mounted on a counter 2 or other suitable support, and located adjacent to the terminus of the dispatch-track 3 and the end of the return-track 4 of a store-service railway. The tracks 3 and 4, as here shown, each consist of doubletrack rails 3 3 and 4 4', respectively, the end of the track 4 being located above the end of the track 3 in a diiferent vertical and horizontal plane.

Upon the upright 1 is mounted a verticallymovable elevator and switching track 5, formed with the track-rails 5 5, connected together at one end by a cross-bar 6 and of a length to bring their other ends adjacent to the ends of the rails 3 3 or 4 i. The switch- .track 5 is mounted on the upright 1 in any ends, an arm 8' projecting laterally from one side of frame 7 and terminating in a sleeve 9, movable on the upright 1, and a cord 10 is fastened at one end to the top. of frame 7, extending upward over a pulley 11 in a slot 12 in the upper end of upright 1 and down through the latter to a drum 13, mounted beneath the counter 2 and controlled by a spring 14 to wind up the cord 10 thereon.

The upright 1 is provided with a dovetail strip 15, terminating at one end adjacent to the top of post 1 and at the other end ashort distance above the counter 2.

The sleeve 9 is formed with two internal vertical dovetail grooves 16 and 17 the groove 17 engaging the strip 15 when the switchtrack 5 is in position to connect with the end of track 3, as shown in'Fig. 1, and the groove '7 16 engaging the. strip when the switch-track 5 is in position to engage the end of track 4, as shown in Fig. 4.

In order to shunt a carrier from the switchtrack 5 onto the return-track 4, the switchtrack 5 is connected to the frame 7 by means of pivot-pins 18, formed with a diametrical angular notch or recess 19, and located in sockets 20 in the lower end of the uprights 8 of frame 7, and having an angular projection 21 equal in size to half of the recess 19. The inner end of the switch-track 5, or that portion thereof on one side of its pivots adjacent to the end of dispatch-track 3, is longer than the portion on the other side of the pivots, or may be weighted so as to counterweight the switch-track 5 and hold it in connection with the end of track 3, one side of the recess 19 bearing against the projection 21. When a carrier runs onto the switch-track 5 from the dispatch-track 3 upon passing the pivots 18, it counterbalances the switch-track 5, tilts it, and is brought to a stop by a depending proj ection thereon striking against the cross-bar 6. At the end of switch-track 5 adjacent to the end of track 3 or 4 it is provided with a lateral pin 22, which as the tilted switch-track 5 is raised into juxtaposition with the end of rail 4 engages an arm 23, projecting from the end of one of the rails 4', and as the switchtrack 5 is raised tilts its inner end into connection with track 4. By this movement the carrier which is at the outer end of switchtrack 5 is caused to be moved over switchtrack 5 and shunted onto the return-track 4.

In use the switch-track 5 is normally held in connection with the terminus of dispatchtrack 3, as shown in Fig. 1, an inwardly-yielding spring-stop 24, projecting through a slot in post 1, engaging the top of sleeve 9 and holding the switch-track 5 from being drawn upward by the action of the spring 14 on the drum 13 and cord 10. In this normal position the groove 17 of sleeve 9 engages the strip 15. Upon a carrier having run onto the switch-track 5 from the dispatch-track 3 and being brought to a standstill against crossbar 6, with the switch-track 5 in a tilted position, the latter is drawn down 011 the post 1 until the sleeve is moved over an inwardlyyielding spring-stop 25, similar to the springstop 24 and in line therewith, pushes in the spring-stop 25, is brought beneath it and be low the strip 15, and is held by the stop 25. The contents of the carrier having been inspected, the switch-track 5 is swung laterally tobrin g slot 16 of sleeve 9into engagementwith strip 15. The switch-track 5 is then drawn up by the action of spring 14 on drum 13 and cord 10, a vertical opening 26in the sleeve 9, with tapering sides 27, permitting the sleeve 9 to pass the spring-stops 24 and 25. The inner end of the switch-track 5 ascending now in the same vertical plane as that in which the end of the return-track 4 is located, and arriving adjacent to the end of track 4,

is tilted by the pin 22 thereon striking beneath the arm 23, and the. carrier on the switch-track is thereby shunted onto the return-track 4. In the upward movement of the switch-track 5 just referred to the sleeve 9 moves over a yielding spring projection 28, having an inclined portion 29 at its upper end and located in post 1 above and at one side of the upper end of a strip 15. Upon the sleeve 9 passing above the spring projection 28 the lower end of the tapering side 27 of opening 26 farthest away from groove 16 is brought above the inclined portion 29 of spring projection 28. The switch-track 5 may then be drawn down by means of a cord 30,

suspended from frame 7, and the inclined portion 29 engages the tapering side 27 of sleeve 9, guides the sleeve 9, and turns it so as to bring the groove 17 into engagement with strip 15 when the switch-track 5 is drawn down on the upright 1 to its normal position, as shown in Fig. 1.

While I have described a specific construction of parts, I do not intend to limit myself thereto, as the parts may be varied without departing from the essential features of the invention.

It is obvious that a weight may be used instead of the drum and its spring, and that the cord 10 may extend outside of post 1 instead of inside; but the latter is preferred as being more sightly and keeping the parts out of the way.

I-Iavingthus described my invention, what I claim as new, and desire to secure by Letters Patent, is
