SPECIFICATION forming part of Letters Patent No. 396,201, dated January 15, 1889.

Application filed September 21, 1888. Serial No. 286,044. (No model.)

To all whom t may con/cern.'

13e it known that we, JOHN \V. FOREST, of Thayer, Neosho county, Kansas, and SAMUEL H. SCOTT, both citizens of the United States, the latter residing at Ohanute, in the county ot' Neosho and State of Kansas, have invented a new and useful Improvement in Oar-Ocupling's, of which the following' is a specification.

The invention relates to improvements in car-couplers; and it consists in the construction and novel combination of parts, hereinafter described,illustrated in the drawing's, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view ot' the end of a car with a draw-head embodying the invention attached. Fig'. 2 is a central horizontal section of two of such draw-heads coupled together, with the chains secured at their inner ends to the locking'- blocks. Fig. 3 is a perspective view of one ot' the locking-blocks detached. Fig'. 4 isa detail view ot' the face of the projection of one of the draw-heads to show the seat therein of one ot' the locking-blocks.

Referring to the drawings by letter, A designates a draw-head suitably secured to the adjacent end of a car and provided with the recess B, into which the projection ct'of the opposite draw-head enters, which projection is rounded at its end, as shown. The said recess is provided with the roof or web l), and with the outwardly-curved directing arm or plate b to guide the rounded end of the projection a of the opposite draw-head into the recess B, the roof or web b of which rides over this projection a. The said projection is provided with the transverse horizontal opening O, having the outer rectangular portion, c, and the inner portion, c', T- shaped in cross-section.

D is a recess in the inner surface of the projection a, having its front and rear sides, d d', respectively inclined and converging inward on each side of the opening O, which forms a seat for the corresponding locking-block, E. The said locking-block has the rectangular shank e seated in the opening C, and is provided on its inner side and end with the opposite flanges or studs c e', seated in the upper and lower extensions of the inner T-shaped portions, c', of said opening. The inner end of the locking-block is beveled outwardly at e2, and it has on its inner side a shoulder, e3, formed by notchiug said edge, which shoulder can catch over the side oi' the outer orice of the opening O, when the locking-block is drawn outward and prevents the latter from being moved inward into coupling position. The end of the projection a is provided with atransverse recess and upper and lower coupling-pin holes to couple with the common link 6o and pin.

F is a strong' spring-bar having' one end secured to the outer side ot' the projection ct and the other end passed throi'lg'h a loop or staple,

f, on the outer end of the corresponding locking-block, and G is a chain having' the coiled spring g secured between its outer and inner sections. The inner end of said chain is secured to the staplef and its outer end to a crank-arm at the Vlower end, 71., of the rod H, 7o

j ournaled in bearings secured at proper points to the end of the car and provided thereabove with the actuating handle or wheel It. The said coiled springA makes the chain elastic, and

thereby prevents breakage when the chain is under tension.

The action of the coupler is as vfollows: Then the draw-heads come together, the beveled ends of the locking-blocks will ride over each other in the recess l) and their rear surfaces 8o will catch' against each other, the locking'- blocks being forced inward by the springs F. The said blocks are unlocked by pulling' on the chains G, either at the sides of the car or from the top by means of the rod H and the wheel l. The combination of the draw-heads, each having' a recess, B, and a projection, CL, the projection a being provided with a transverse opening having' a rectangular portion, c, and

a T-shaped portion, c', and the locking-block having a rectangular portion fitting in the loo The flanges 9o portion c of the opening, and the flanges e', ourown we have hereto affixed om' signatures fitting n the T-Sllaped port-ion thereof, as in presence of two Witnesses. Specified. T f
