SAN'IFORD P. COAN, OF MEDICINE LODGE, KANSAS.

CAR-COUPLING.

SPECIFICATION forming part of. Letters Patent No. 260,941, dated July 11, 1882.

' Application tiled April 15, 1882. (No model.)

To all whom it may concern:

Be itknown that 1, SANTEORD P. Conn, of Medicine Lodge, in the count-y of Barbour and State of Kansas, have invented certain new and useful Improvements in Oar Coupliugs; 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 makeand use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a perspective view ofr the t'ront end of a box-car provided with my improved' car-coupling. Fig. 2 is a plan or top view of the draw-head. Fig. 3 is a side elevation of the same. Fig. 4 is a perspective view of the two draw-heads coupled. Fig-5 is a perspective detail view of the stirrnp device for adjusting the elevation of the draw-bar and draw-head. Fig. 6 is a sectional view ot' the same, showing the draw-bar inserted through the stirrup. Fig. 7 is a perspective view of my combined latch and link and Fig. S is a top view, showing the application of the latter to the draw-head.

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

My invention has relation to automatic cnrcouplings or so-called self-couplers, and it consists in the improvements which will be hereinafter more fully described, and particularly pointed out in the claims.

In the accompanying two sheets ot' drawings, A represents the front end-of a box-car provided with my improved automatic coupling.

B B are the bumpers or buffers/7 to one or both of which I aiiix a block, C, which is secured at the outer end of an arm, D, that in turn is fastened to a rod, E, that works in staples or keepers e aand has a handle, E', at its upper end. By turning this handle arm D, with its block U, may be swung to one side out of the way, as shown in dotted lines in Fig. l; or the same may be done from either side ofthe carby means of a rod, F, which is pivoted upon a stud or pin, d, on arm D, and extends to'opposite sides of the car. It desired, springs may be employed to retain block G in either of its positions, so that when swung into place in front of the buffer-beam it will not swing out accidentally, or vice versa; or other means may be employed to effect the same result. The swinging block C, it' made of wood, should be shod or faced with iron, and provided with a rubber cushion to takeup the shoek'when the cars come together. When swung into place in front of the buffer-beam it will prevent coupling of the cars by preventing the draw-heads from engaging with one another. A

Each of the draw-heads Gr is cast with a projecting hook, g, and a recess, H, extending I '14. Thus it will be seen that tbe piece composed of the parts I, I', I2, I3, and I4 (which, for the sake of brevity, I shall denominate simply part I 7) is hingedin the top part of the draw-head, and actuated by the spring K, which keeps it down upon the draw-head Hush with its top. Part I is provided with a forwardly projecting curved arm, L, and a laterally-projecting arm or linger, M, and the play ot the part is limited or controlled by a stirrup or keeper, N, which spans the drawhead.

In coupling the draw-beads, the hook G of one will enter the recess H of the other, the beveled 4head ot' the hook, as it strikes cross-bar I4, raising part I until the hook slips under the bar, when spring K will force bar I4 down into the notch of the hook. The projecting curved arm L of one of the parts, l, striking the latterally-projecting finger M ot' the draw-head opposite, operates in like manner as the beveled hook-viz., raising part I so as to permit the hook to enter its recess freely.

To uncouple the cars (which may be done either from the roof or from the sides of either car) -the parts I are disengaged from their respective hooks g, with vwhich they are inter- IOO locked, by a rod or chain, O, the upper end ot' which connects with an arm, p, projecting from a rod, P, having levers or handles P P at its ends. Another rod, Q, extends from arm p up to the roof of the car.

Ifit is desired to use this draw-head with couplings of the ordinarjT link-and-pin 7 description, I use the combined latch and link shown in Figs. 7 and 8, by coupling it with the hook and latch of the draw-head, with its link-shaped end, W, projecting in front ofthe ook, so that it will enter the mouth of lthe draw-head opposite.

Where my improved draw-head is used withv cars of different height, its elevation may be adjusted by means of the device shown in Figs. 5 and 6. This consists simply of a stirrup, R,throu gh which the draw-baris inserted, and which is cast with a plate or extension R, having two slots, if ands. Plate R works in a vertical slot in a beam, S, which is bolted upon the front side of the car.

T is a bell-crank, the shaft tot" which passes through the Vertical slot i' of plate R', and has an arm, u, the bent outer end, u', of which works in the horizontal slot s. Thus by turning bell-crank T(by means ot rods connecting it with the sides and root' of the car,) its bent arm u u' will raise or lower plate R and its stirrup R, and with it the draw-head.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United Statesl. In a car-coupling, the combination of a draw-head having the projecting hook g, recess H, and channels a a' a2, hinged part I, provided with the projecting.;` arm L and iin ger M, set at right angles to each other, and spring K, constructed and combined to operate substantially in the manner and for the purpose herein shown and described.

2. In acar-coupling, the combination, with a hinged draw-bar and draw-head, of the stirrup It, having plate R', slotted at i' and s, bellcrank T, having shaft t and bent arm u u', and slotted beam or keeper S, constructed and combined substantially as and for the purpose herein shown and described.

3. The swinging buffer-block C and means for operating the same, in combination with the butter-beam and draw-head of a railwaycar, arranged to operate substantially as and for the purpose herein shown and specified. Y

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