CHARLES LOUIS MUELLER, OF HUMBOLDT, MINNESOTA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 337,780, dated March 9, 1886.

Application iiled December 30, 1885. Serial No. 187,156.

4To all whom, it may concern:

Be it known that l, CHARLES Louis MUEL- LER, a citizen of the United States, residing at Humboldt, in the county of Clay and State of Minnesota, have invented certain new and useful Improvements in Gar-Couplings; and I do hereby declare the following` to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to draw-heads, and particularly to that class in which the strain imparted in drawing the cars or in receiving` the impact of adjoining carsin coupling is received upon a reciprocating plateheld in place by a spring.

The object of the invention is to produce a draw-head in which those parts upon which there is any great amount of friction or wear shall be strengthened, in order to retain the different parts in their proper places and to successfully withstand the hard usage to which draw-heads are usually subjected.

Vith these objects in view my invention consists of a draw-head in which the draftbars are provided with protecting-plates of peculiar and novel forni so disposed as to protect the bars from becoming worn, and in this way allowing` the parts resting thereon and moving in contact therewith from becoming displaced. Further, the invent-ion consists in various novel details of construction, whereby the parts are retained in their proper relative positions.

In the accompanying drawings, forming part of my specification, like letters of reference indicate corresponding parts.

Figure l represents a horizontal longitudinal section of a draw-head made in accordance with my invention. Fig. 2 is a plan view of one of the plates employed to protect the wearing-faces of the draft-bars, showing also the cleats or lugs placed upon and secured to said plates for the purpose of limiting the movement of the spring-actuated followers. Fig. 3 is a section taken on the line c a of Fig. 2. Fig. 4 is an inverted plan view of the protecting-plate. Fig. 5 is an end View of the plate and lug. Fig. 6 is a plan View of the lug; and Figs. 7 and 8 represent, respectively, side and end views of the retaining-lug.

(No model.)

In these figures, A represents the protecting or wearing plates,which are of a length to extend over all that portion of the draft-bars against which the moving parts of the drawhead bear. The ends of these plates are bent at right angles and form the projections a which enter the draft-bars and aid in retaining them in place on the same, and have the mortises or slats B and holes E for the reception of retaining devices, by means of which they are held to the draft-bars.

H H represent follower-plates, which are situated between the draft-bars and bear against and slide in contact with the plates A. To these followers I attach the coupling-bar J, which is provided at its inner end with the loop K, which incloses the rear follower H, and this bar is retained in proper position by means of the pin L, which in turn is held in position by the pin m. The pin L extends from the said bar and through the two followers, and is prevented from moving out by means of a pin, m, passing through the bar and remaining in contact with the end of the p1n.

I is a coil-spring of proper rigidity interposed between followers,which forms a cushion or yielding bed to receive the strain exerted in drawing the cars or in coupling by running one against the other.

As a convenient means oflimitiug the movement of the followers and retaining them in proper position, I provide the lugs l), having the square inner faces, F, and the tenons C, which enter slots or holes in the wearingplates and the draw-bars, and when in position serve both to keep the lugs in place and to hold the wearing-plates in position, and

.bolts b are passed through the lugs, wearingplates, and the draft-bars and serve to retain the parts in proper place.

From the foregoing it will be clear that a draw-head made in accordance with my invention will be much more durable and reliable in operation, by reason of the fact that the parts will always be retained in their proper positions and not liable to become displaced by being worn, for the reason that the plates A,upon which most of the wear comes, may be readily removed and replaced by others, while in the ordinary form of draw-heads the wood IOO of the draw-heads is exposed and'soon becomes worn, causinga displacement of the operative parts. l

Having thus described myinvention, what 5 I claimas new, and desire to secure by Letters Patent, is-

In combination, With the draft-bars and the follower-plates, the wearing-plates provided with bent ends entering the draft-bar and 1o provided with slots or openings, and the lugs provided with tenons entering the slots in the plates,` andthe bolts passing through the said lugs,wearingp1ates, and draft-bars, substantially as described.

In testimony whereof I aix my signature 15 in presence of two witnesses.
