DRAW-BAR.

ESIECIPICATION forming part .of Letters Patent No. 336,388, dated February 16. 1886.

Application tiled December 30, 1885. Serial No. 187,074.

To aZZ whom it may concern.-

Be it known that I, J OSEPH N. CruLsoN, a citizen of the United States, and a resident of Streator, in the county of la Salle and State of Illinois, have invented certain new and useful Improvements in DraW-Bars and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a bottom view of as much of the platform or floor of a railway-car as will show my invention. Fig. 2 is alongitudinal vertical section of the same on line war, Fig. 1. Fig. 3 is a horizontal section on line 9 3 Fig. 2; and Fig. 4182!. perspective View ofthe casting comprising my improvement.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to draw-bars and bearings for the same for railway-cars; and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the draw-bar, which has the drawhead B, which may be of any suitable construction, and the reduced inner portion, 0,

which forms a rearwardly-faoing shoulder, D.

E is the bottom or platform of the car, and FF are the draw-timbers, between which the draw-bar is placed and slides. The forward ends of the draw-timbers are connected by a bar or yoke, G, bolted to the timbers, and near the inner or rear ends of the timbers they are connected by the casting or bearing H, which is the principal feature of my invention, and which is formed with a longitudinal bore or perforation, I, in which the reduced end of the draw-bar slides, the drawbar having coiled springs J, bearing against the faces of the bearing and against the rearwardly facing shoulder of the draw-bar and against a removable collar, K, secured to the inner end of the draw-bar by means of a key, L, passing through a slot in the draw-bar, the springs being coiled around the bar and cushioning the same either for a draw or a push upon it.

(No model.)

The bearing consists of the perforated body M, the upper and lower sides of which are so recessed at both sides of the middle as to form a portion of the cylinder-surface concentric with the perforation through the casting, as shown at N, and the ends of the casting or bearing rest in rectangular recesses O U in the inner faces of the draw-timbers. These recesses have again sub-recesses or rectangular grooves in the middles of the inner sides, the said grooves running vertically, and vertical wings P P project from the ends of the casting or bearing and fit into the grooves Q Q. The outer edges of these wings or ribs are concavelygrooved, so as to form sharp edges R. R at the side of the grooves S, which edges will bite into the bottom of the grooves in the draw-timbers. The bearing is formed with two transverse perforations T T-one above and one below the longitudinal bearingperforationand these perforations register with transverse perforations U U in the draw -timbers, and have nutted bolts V V passing through them, which bolts secure the casting between the timbers and draw the timbers to bear with their recesses and grooves against the ribbed ends of the casting, forcing the grooves. It will thus be seen that the draw-bar will have a bearing with its springs against the casting, and that the said casting will be rigidly secured between the draw-timbers, the ends of the casting and the ribs gearing in the recesses in the inner sides of the timbers, relieving the bolts from some of the strain upon them.

The casting may be readily removed or inserted in the case of repairs being necessary, or whenever it is desirable to remove or insert the casting, by simply drawing the drawbar out of the bearing and thereupon removing the bolts, when the casting may be slid downward and out from between the timbers, the procedure being reversed when the casting is to be inserted.

The upper and lower sides of the casting being recessed or grooved, so as to give the said sides a cylindrical shape at their middles, will allow a saving of metal in manufacturing the casting, without depriving the casting of any strength, the removed metal being useless.

Having thus described myinvention,I claim the sharp edges of the ribs into the bottoms of and desire to secure by Letters Patent of the United States 1. A bearing for the draw-bar of arailwaycar, consisting of a longitudinally-perforated body having the upper and lower sides cut away to form cylindensurfaces at the middles of the same concentric to the perforation, and vertical ribs at the ends having their outer edges grooved to form sharp edges, the body and ribs having transverse perforations above and below the longitudinal bearing perforation, as and for the purpose shown and set forth.

2. In combination with a draw-bar of the usual construction and having two coils of springs placed around its reduced inner por-i tion, the draw-timbers connected at their forward ends by means of a yoke or bar and having vertical recesses in their inner faces near the rear ends, formed with vertical grooves in their bottoms,and a casting having a longitudinal perforation for the reduced end of the draw-bar and having the springs hearing against its faces, having its ends fitting in the recesses in the draw-tim bers and formed with ribs having vertical grooves in their outer edges fitting into the grooves in the bottoms of the recesses, and having transverse perforations above and below the longitudinal perforation registering with perforations in the timbers, and having nutted bolts passing through them, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
