IMPROVEMENT IN CARS FOR TRANSPORTING COAL.

Specification forming part of Letters Patent No. 152,630, dated June 30, 1874; application filed November 28, 1873.

To all whom 'it may concern:

`Be it known that I, JOEL HAINES, of West Middleburg, in the county of Loga-n, Ohio, have invented an Improvement in Coal-Cars for Railways,of which the following is a specilication:

This invention relates to means for loading, transporting, and unloading coal.

The irst part of the invention consists in a detachable truck or frame for application to a common flat railway-car, or gondola, and provided with sloping-sided dumping-boxes, which are lled in the mine, then loaded on the car, and, on reaching their destination, are lifted oft' and readily dumped to discharge the load.

The second part of the invention consists 'in a traveling derrick applied to the car, or

to a train of cars, for'lit't-ing the boxes to and from their seats.

The third part ot' the invention consists in a peculiar grapple, by means ot' which to susmay be the platform or deck-frame of an ordinary hat car, or gondola, which may, if preferred, be untloored, as in the illustration. A truck, B,is applied to the deck A by means of standards z, attached to the truck, and entering the ordinary sockets y. This truck is a rectangular frame, with vertical sides and ends, of which the former areconstructed with sloping-sided notches w, which form seats for boxes C, having' bottoms of corresponding shape. These 'boxes are equal in length to the width of the car, and in width and height they are of variable dimensions. Their sides are parallel, inorder that they may load closely together. Their ends are likewise parallel, and are strengthened and enlarged by means of plates fw. These may serve to prevent vthedisplacement of the boxes, but cleats o are preferably applied to the bottoms ofthe boxes for this purpose. The end plates w are constructed with pivot-sockets l, by which to suspend the boxes, and arranged below the center of gravity, so as to facilitate dumping; also with sockets 2 at one end, to receive a locking-pin. A derrick, D, and a grapple, E, applied thereto, constitute the means for handling the boxes. ln the illustration a traveling derrick is employed, dovetailed ways u being formed in or attached to the edges of the platform A for its reception. The carriage t of the derrick consists of a strong frame, which is prevent-ed from spreading by the doveta-iled ways. A turn-table, s, is pivoted to the top of this carriage so as to swing horizontally, and on this a fulcrumpost, r, and a windlass, q, of approved construction are mounted. In the fulcrum-post a lever, p, is pivoted at, say, one-third of the distance between its outer end,where it carries the grapple E, and its rear end, where it is connected to the drum of the windlass q by a rope or chain, o. The windlass is preferably furnished with power-multiplying gear 3; but, owing to the employment of the liftinglever p, a single spur-wheel and pinion will be suflicient. A retaining-pawl, 4, Fig. 2, is also applied to the windlass. A forked standard, n, which may constitute a part ot' the windlass, receives the rear end of the liftinglever when a box is elevated, and supports the same laterally. The weight of the box is sustained by the holding-pawl el, and the box is swungoft' to either side of the car by means of the turn-table. The grapple E, for suspending and dumping the boxes, is attached to the lifting-lever by means ot' a shackle, on, so as to swivel, to some extent, at least. The grapple is composed of a pair of jaws, Z, a fulcrumstrut, k, and suspension-links i, uniting the jaws, and a latch, h, hinged to one of the jaws l, to engage with the locking-sockets 2, to prevent the premature dumping of the boxes. Each of the jaws carries a suspending-pivot,

to engage with the pivot-sockets l of theA boxes. The parts of the grapple are so constructed and arranged that the weight of the suspended box tends to press the jaws together, and the accidental unshipping of a box is thus precluded. When a box has been swung into proper position it is released by lifting the latch h, and it is then readily dumped by turning it on its pivots l, as illustrated in Fig. 2. rlhe empty box may be returned toA its seat and detached by loosening the shackle, and the derrick may then be shifted so as to bring the shackle over another box, as illustrated by dotted lines in Fig. l, and thus each of the boxes may be removed, dumped, and replaced. When one car has thus been emptied the derrick may be transferred to another, the carriage being adapted to span the spaces between the cars, and an entire train may thus be unloaded or loaded; or xcd derricks at the loading and unloading points may be employed, in combination with cars otherwise constructed according to this invention, as illustrated in Fig. 3. It is designed that the boxes shall be filled in the mine and then lifted to place. In returning to the mine a large number of trucks and boxes may be carried by a single car, and the cars thus cleared may be used for return freight; or the cars may be thus converted at any time. The multiplication of cars, in providing for carrying and dumping coal, is thus obviated, While most effective and simple means for this purpose is provided. The number of boxes to be carried by each car will be determined by the length and capacity of the flat cars of the different roads on which the invention is employed.

rlhe following is claimed as new:

l. The detachable truck B and the dumping-boxes C, in combination with an ordinary flat car, A, for carrying' coal, in vthe manner set forth.

2. The traveling' derrick D, composed of a carriage, t, turn-table s, fulcrum-post o", liftinglever p, Windlass q, and rope or chain o, in combination with a car or cars, A, furnished with Ways u, substantially as and for the purposes specied.

3. The grapple E, composed of jaws l, fulcrum-strut k, links i, and latch L, in combination with a derrick, D, and dumping-boxes C, substantially as described, for the purpose specified.
