DUMPlNG-CARQ SPECIFICATION formingpart of Letters Patent No. 280,735, dated July 3, 1883.

Application tiled February 3. 1883.

To all whom it may concern:

Be it known that I, J osErH H. GARTSIDE, of Pittsburg, county of Allegheny, State of Pennsylvania, have invented certain Improvements in Dumping-Oars, of which the following is a full and complete description, such as will enable others to construct and use the same.

The object of this invention is to improve that class of cars used for the purpose of removing slag or cinder from blast-furnaces. In the cars heretofore commonly used for this purpose much difficulty has been encountered from the nature of the material to be removed,

as its great heat, when flowing from the furnace, forbids the use of anything but refractory substances for those parts of the car with which it comes in contact; and as these substances are generally of a brittle and more or less fragile nature, they require the support of a metal backing, which is liable to serious injury from sudden contraction and expansion to the extremes of temperatureto which it is exposed. Another trouble is caused by the diificulty of removing the contents of the receptacles when solidified, as the slag flowing into them takes the exact form of their interior, and all inequalities of surface from keys, which tend to prevent the block of solid cooled slag from leav- 0 ing the receptacle in which it is molded. To avoid these difficultieslhave constructed a car the trunk and body of which are wholly of metal, the body being so formed from segments of limited area as to avoid all danger of damage 3 5 to the same from sudden contraction or expansion of-the metal of which it is constructed; and, further, its shape is such as to readily allow the removal from it of the block of cooled slag before the latter is dumped from the car-platform upon which it rests.

My invention consists, therefore, in the construction and arrangement of the several parts of the car, as will be hereinafter fully described, and then specifically stated in the claims.

In the accompanying drawings, Figure l is a side elevation of the car complete. Fig. 2 is an end elevation of the same; and Fig. 3 is a plan of the truck, showing its construction and the general arrangement of its parts.

Similar letters indicate like parts in all the figures.

(No model.)

A represents the truck-frame, in which a a are the principal parts, formed of channel-iron, connected at the corners by angle-pieces I) b, properly fitted and firmly secured to the parts a c by rivets. The cross-bars c c of the frame are formed of fiat iron,having their ends bent at right angles, and secured to the channelplates a a by rivets. To these cross-bars, as well as the channel-plate frame, is secured the longitudinal draft-beams d d, between which is located the draw-bar V, with its springs 16 and follower-plates, the draw-bar and springs being retained in place between the draft-sills by bridles pp, which are attached to the draftbeams at each end and pass below the drawbars. To the frame A are attached the pedestals q g, which retain the axle-boxes in place, while resting upon the boxes are the bodysprings s s, carrying the truck-frame. The wheels and axles may be the same as those in common use.

Connected with each end of the truck-frame, by means of supports ff, are the carrying-bars E E, which present a flat upper surface pierced 7 5 with a series of holes for the reception of guidepins attached to the rocker-bars G G. These rocker-bars are formed,preferably, of fiat iron, curved so as to present a convex face to the carrier-bars, upon which they rest, and are provided with a series of pins, which register with the holes in the carrier-bars, causing the rock er to retain its position and oscillate in a straight line upon its carriers. Two additional pins are inserted in each rocker-barone near each endwhich serve as stops and prevent too great an oscillation. Supported upon the rocker-bars E, and firmly secured thereto, are the floor-sills h h, which are preferably formed of channel-iron and carry the floor-plates '0' 2', which are riveted to the sills with countersunk rivets, thus presenting a smooth, unbroken upper surface, so as to allow the load to slip easily therefrom when the floor is tilted.

The car box or body B is of rectangular shape, corresp ending in dimensions with the car-floor, and is formed by placing at each corner a post, J, having an L-shaped section. These posts incline toward the center of the body, their fiat sides being wider at the bottom than at the top, so that, notwithstanding their inclination, the distance between any two of them shall be IOO the same at either top or bottom. Filling the spaces between these posts, on both sides and ends of the body, is a series of sheet-metal staves, L- 70, which, as well as the posts, arc 'se eurely riveted to the encircling bands I I, which hold the several parts of the body firmly in place.

Attached to the sides of body B are the straps a provided at their upper ends with eyes, to which is attached the hoisting apparatus by which the body is raised from the cariloor, when desired. There are also connected to the outer sides of the body a series of hinged clamps, d, by which it is secured to the floor, when desired, but which, when the body is to be removed, are unhooked, thus allowing it to be lifted from the floor;

In order to retain the car-body in ahorizontal position while it is being filled and transported to the dumping-ground, stops N are pro vided, which are placed. between the rocker and carrying bars and secured by a pin, that may be easily knocked out and the stops removed when. it is desired to dump the car.

Having thus described the construction, I will now explain the manner of using the car, which is as follows: The body having been placed in position upon the floor and securely locked thereto by means of the clamps, its interior, as well as the floor, is covered with a coating of loam or other refractory material. The car being then run under the cinder-spout, the furnace is tapped, and the liquid cinder or slag allowed to run into the ear-body until it is full, when the car is run out upon a suitable track, and another, similarly prepared, takes its place under the spout. The loaded car may then be allowed to cool gradually; or this may be hastened by the application of water, the construction of the car-body in sections giving play to the several parts without danger from the sudden contraction, and allowing this ineth od of cooling the slag to be employed with impunity. When themass has become solid, the car is run to the dumping-ground, at which point one rail. is preferably higher than the other, so as to slightly tip the car. A crane or other hoisting apparatus is then attached to the eyes upon the body and the clamps unhooked, when the body maybe raised from the car, leaving the slag in a solid cubical mass resting upon. the floor of the car. The stops are now removed from between the rocker and carrying bars, and the floor or platform slightly tipped, when the slag slides oil, and the floor is returned to a horizontal position. to receive the body.

It will be apparent that, if desired to save time, the body may be placed upon the floor of another car that has been already unloaded, as the parts are all interchangeable.

Having thus described my invention, I claim as new and desire to secure by Letters Patent the iollowing:

1. In a dumping-car, a removablebody composed of a series of staves inclined toward the middle of the body and secured together by hoops and to the lloor by suitable clamps, all combined and arranged substantially as and for the purpose specified.

2. The combination, in a dumping-car, ot' a metallic truck-frame, an oscillating iloor attached to said frame, and a removable body composed of a series of inclined staves, all arranged and opera-ting as set forth.

3. The combination, in a dumping-car, of an oscillating iloor composed of a series of metallic plates riveted to the floor-frame, a body formed of staves, clamps for securing the body to the iloor, and a refractory lining covering the inner side of the body and the floor, all the parts being arranged for joint operation substantially as and for the purpose described.

In testimony whereof I. have hereunto set
