SLAG-BUGGY-TRAIN COUPLING.

SPECIFICATION forming part of Letters Patent No. 573,724, dated December 22, 1896.

Application filed February 21, 1896. Serialllox 580,172. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH L. THOMSON, a citizen of the United States of America, and a resident of Bayonne, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Slag-Buggy Trains and Couplers, of which the following is a specification.

Myinvention relates to an improvement in slag-buggy trains and also to a device for coupling the slag-buggies which make up the train together in such a manner that they shall form a train of the character hereinafter indicated.

In ordinary blast-furnace practice the slag as it issues from the furnace is tapped into conical or hemispherical pots mounted upon a pair of wheels, and, after filling, the pots are wheeled off by the handle. Ordinarily slag-buggies used in practice are so large and clumsy that they can only be removed by hand separately. In order to facilitate an easy and efficient removal of the slag, I employ a buggy of the character hereinafter shown, which is larger than the ordinary buggy. It is of such size that two or more of the same byco upling orlocking together may be formed into a train of buggies, which train may be removed by a horse or may be attached to a rope connected with a Windlass and dragged off from time to time when full. In order to effect the coupling or locking of the buggies together, at the same time to provide an unlocking and the emptying of the same at will, I provide a locking device of the character hereinafter indicated.

The invention will be best understood by reference to the accompanying sheet of drawings,which is hereby made apart of this specification, in which- Figure 1 shows a train of slag-buggies coupled together as hereinafter described; Fig. 2, a rear elevation of a single buggy; Fig. 3, a plan view of the same; Fig. 4, a side view of the coupling device proper, and Fig. 5 an end view of the same on the lines 5 5 of Fig. at.

Similar letters refer to similar parts throu ghout the several views.

In the drawings, A represents the body or by it is pushed or pulled by the workman, and

which cross-bar serves also to prevent the handle from being removed from the coupling device after coupling.

The body A of each buggy composing the train'is provided at the upper edge opposite to the handle B with a projection or lug P, preferably cast thereon, to which the coupling device is attached and to which is attached a plate M, carrying two vertical lugs N and N. The vertical lugs N N are provided with the openings S S, Figs. 4 and 5, which are of sufficient size to permit the insertion of the bar F, which serves as a lock to the coupling device. The bar F is provided at one end with the eyeF, by means of which it may be removed.

To couple the buggies together, the handle of any buggy has simply to be dropped into the opening between the lugs N N until the buggy-handle rests in the position shown in Fig. 1 between the vertical lugs N and N. The pin F is then inserted, and in this way the coupling is locked. In order to empty the buggy when it is uncoupled and to prevent it from tipping over, a leg R with a roller R is provided, attached to the pot A directly under the handle 13, and when the buggies are uncoupled the balance of the pot is such as to cause it to tip downward and rest upon this leg.

In order to uncouple the train, the workman has simply to take a hook and insert it in the eye F of the pin F and draw or otherwise remove the bar, whereupon the handle may be lifted out of the vertical lugs N and N and the buggy may be dragged off by the handle and emptied.

I claim as my invention In a slag-buggy, the combination with the edge of a pot, of a locking device composed of two vertical lugs placed upon the edge of the pot, between which the handle of another pot havinga suitable cross-bar is inserted, so ence of two witnesses, this 20th day of Febthat the same may be coupled up in a line ruary, 1896. behind the first pot, and a suit-able pin for JOSEPH L THOMSON holding down the handle with which the cross- 5 bar on the handle of the second pot engages. Vitnesses:

In testimony that I claim the foregoing as HENRY H. GRAFF,

JOHN FRENCH.
