CAW-HANDLING DEVICE.

Specification of Letters Patent.

Patented Aug'. 22, 1905.

Application filed August 25, 1902. Serial No. 120,934.

To all whom, t may concern,.-

Beit known that I,Jo1-IN V. ScHAnFER,a citi- Zen of the United States, residing at Chicago,

in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Car-Handling Devices, of which the following' is a specification.

My invention relates to car-handling devices, and particularly such as are intended for conveniently handling cars where loaded and empty cars are to be carried over inclined surfaces.

I have shown in my drawings, somewhat diagrammatically, oneform of device in which my invention is made use of.

Figure 1 is a diagrammatic plan view. Fig. 2 is a diagrammatic longitudinal section. Fig. 3 is a side elevation of a portion of the driving mechanism. Fig. 4 is a part cross-section and elevation view substantially on the line t 4, Fig. 3. Fig. 5 is a side elevation of the trolley and spring-actuated pusher. Fig. 6 is a cross-section on the line 6 6 of Fig. Fig. 7 is an elevation of the trolley-carrying and fixed pusher.

Like parts are indicated by the same letter in all the figures.

A is the shed, for example, at the top of a mine from which the loaded cars'are had. A is the iioor of such shed.

B B are the rails of the two tracks, which in this case side by side run up a slight incline way from vthe receiving-shed and down along the incline to the delivei'y-ljioint.

C is the delivery-floor.

D D are the cars, in this case coal-cars.

E is an endless chain which passes through a suitable slot or between the rails down under the iioors A and C.

Referring to Figs. 3 and 4, FF are suitable supporting-timbers, and mounted on them in a vertical position is the shaft F', carrying the sprocketwheel F2, around which travels the chain E. On this shaft is the gear-wheel F, meshing with the gear-wheel Fl on the shaft F 5, which carries the bevelgear F, meshing with the gear F7 on the shaft F, which shaft carries the'driving-pulley F9 or may be driven by any desired power. F10 is a brake-wheel on the shaft F8, controlled by the lever-arm F11, associated with the supporting-arm F12. By means of these several parts the operation of the driving sprocketwheel may be controlled so as to drive the chain, and thus move the cars in any desired manner or speed. The cars must be connected with the chain, and the mechanism for so doing' is shown in Figs. 5, 6, and 7. G is a trolley-link inserted in the chain E and provided with down wardly-projecting parts G G at its ends. Each of these parts terminates in the piece G2, which is placed in opposition to a similar piece G3, on which latter piece is formed the bearing G'L for the axle G5, which carries the two trolley-wheels G G, adapted to run in the angle-iron rails G7 G7. The bearing GEt will be seen to be enlarged toward both its ends from the middle, so as to give the trolley-axle G5 a certain amount of play. The parts G2 and G3 are held together by the bolts Gs The trolley-link is inclosed by two blocks G9 G, which are held in position by the pins G10 G1, and on the outside of these blocks rise the stops composed of the two side blocks G1l G, which are held together and pivoted on the cross-bolt G12 and by the cross-bolt G13. From this latter bolt proceeds the spiral spring G, its other end being connected to the pieces G2 and G. The upper ends of the parts G1I are inclined, as indicated at G15. The stop is therefore free to move at its upper end toward the right in opposition to the action of the spring G1* and is held from moving in the other direction by the engagement of the cross-pin G1 with the lower ends of the blocks GJ G".

In Fig'. 7 I have illustrated the fixed pushers. The several parts are the same as those illustrated in Fig. 5, except such as relate to the pushers themselves. Here I show attached to the link G pushers J J, similarly shaped as the stops Gu G, but set on the chain in such a way that the inclined faces J' of each faces in the opposite direction from the inclined faces G G15 on the stops Gu G11. The pushers J J are secured in.position by the cross-bolts J2 J2.

The trolleys are placed along the chain alternately and are spaced so that there is approximately one car length between each pair.

The cars D D are provided with the end cross-beams D DL and are mounted on the wheels D3 D3, which run on the tracks B B.

At the head of the shaft or in the shed A is mounted horizontally asprocket-whecl K and around which the chain E travels. This sprocket-wheel is mounted on the shaft K', which carries the pinion K2, and there may be at this end of the line a duplicate of the driving mechanism at the other end of the line, or either end may have any desired mechanism, or one end may have the driving mechanism and the other simply an idler to give the chain its proper direction.

I have not shown the rails, switches, &c., which extend beyond theends of the chain E, as of course any desired arrangement of these parts can be had.

I wish, as previously suggested, to have my drawings taken in the largest possible sense as diagrammatic, and I wish it understood that various figures of my device could be modilied without departing from the spirit of my invention.

The use and operation of my invention are as follows: Ie will assume that the chain is traveling in the direction indicated in Fig. l, that in Fig. 2 we are looking at the ascending side, and that the chain, with its trolley-pushers, is traveling as indicated by the arrows in Figs. 5 and 7. Obviously the stops GH Gr1l will engage the first car pushed up onto the rails from the point where the chain with such pushers rise through the floor C. The stops, however', will present to the beam D the inclined faces G15 G15; but the weight of the car will prevent its motion, causing the spring Grl4 to yield and allow the stops to descend and pass under the beams of the car and again assume their upright position, as indicated in the several drawings. Since the distance between the stops and the pushers of each pair is approximately equal to the length of one of the cars, by the time this action has taken place the fixed pushers J J will have reached the car and will engage its rear beam D. The further motion of the chain will carry the car up the incline, as indicated in Fig. 2, and when the car begins to descend the rear beam D will leave the pushers J J and the car will roll forward until the forward beam D2 engages the stops G11 Gu, and the car by reason of its weight is held against the stops and continues its motion until it passes ofi' on the rails along the floor A. In like manner when the loaded cars are standing, for example, in the shed A in proper position and the chain is returning the action will be repeated, but in this case the car will be carried up the short incline by the pusher and will be sustained by the stop as it passes down the long incline. It is quite obvious that any irregularity of the ground over which the cars are to travel can thus be compensated and the cars can be controlled regardless thereof. In ordinary practice the loaded car is pushed onto the track to a point just beyond where the chain and the trolleys come up to the iioor and there the car stands. The first stop being hinged and held upright by the spring when it strikes the car is depressed and slips under the car and comes up in front of it. The pusher being' rigid engages the car by striking against its rear end and pushing it along. On the downgrade the car runs forward against the stop and is held rigid. Thus the car is held between the pusher and the stop. hen the lower end is reached, the forward stop passes down through the iioor and the car runs olf freely. I am enabled to bring about these results by the association of the stops and the pushers, the stops being hinged or spring-actuated. I am also enabled in this manner to use a single chain instead of using two chains with the fixed stops or pushers as heretofore.
