IMPROVEMENT IN CAR-COUPLINGS.

To all whom it mag concern! Be it known that I, SAMUEL D. UCK ER, of

(lircleville, county of Pick-away, State of Ohio, have invented certain new and useful Improvements in Oar-Couplings, of which the follow ing is a full, clear, and exact description, reference being bad tothe'accompanying drawing, making part of this specification, in

- which- Figure 1 represents a vertical section through two draw-heads, showing the arrangement of the coupling devices; and Fig.2 is a perspective view of one of they draw-heads with the coupling-latch raised.

Similar letters of reference denote corre' 'sponding parts in both figures.

. In the accompanying drawing, A A represent two draw-heads, which may be of the usual construction, adapting them to employ the link in common use, and provided with the usual flaring mouth, adapted to receive and guide said link to place. The upper wall of this hollow draw-head has an elongated slot, a, cut through it, and within this slot is placed a stout hook or latch-bar, B,pivoted at its'inner end in the draw-head by a transverse horizontal pivot at I), upon which the bar B is free to rise and fall within certain limits in the slot at. The outer swinging end of the pivoted bar B is, by preference, made in the form of a pendent hook or latch, (indicated by the dotted lines, Fig. 1,) and surrounding, or partially surrounding, this hook or latch end is a strong metal latch or plate, 0, bent into U shape, the vertical closed portion of said plate forming the part engaging the link, as shown. The outer face or open end of this plate or block 0 is cut away at its I upper corner,'formin g a notch or shoulder, c,

from which said outer face is made to recede downward to a point, 0 formingan inclined face, against which the link acts for automatically raising the latch in coupling the drawheads. The partof. the plate or block 0 extending below the-point'c when the block is in position, passes through a slot, a, in the lower wall of the drawhead, and the forward face of the block below said point e is made p more nearly vertical, adapting it to rest against the forward wall of slot a, and thus to form one of the points of support of said block or latch against the strain or draft of the coupling-link. When in this position, the

shoulder 0 passes underneath the upper wall of the draw-head in front of the slot at, and the vertical shoulder a" is drawn against the forward wall of said slot, and serves as another point of support to the block or latchagainst the strain of. the link, while the shoulder c, passing under the upper wall of the draw: head in advance of the slot 0., as explained, efl'ectually locks the blockor latch O in place when under tension. The loekin g block, latch, or plate 0, thus constructed, is con'pected with the pivoted bar or latch B by a" transverse pin, b, arranged in rear of the center of grave ityof the block, and passing through horizontal or slightly-inclined slots d in-the sides of the bent plate 0, at or near'its rear upper cor-' ner. The upper wall of this slot d isinclined or curved downward toward the front or outer end of the draw-head, as shown, in such mangravity will cause it to ride forward on the pivoting-pin until the shoulder 0 passes under the draw-head, as explained, and-.locksit in place, and the weight of the block, in connection with the inclined or curved face of the slot, as described, serves to hold it there when it is not held by the link under tension.

For withdrawing the locking block or latch, it is provided at its rear upper corner with a pivoted link, ball, or handle, D, by means of which'.th e attendant can draw the block or latch 0 back out of engagement with the drawhead, when, by lifting on the link or handle,

the pivoted bar B rises and lifts the block or plate 0 out of the link, uncoupling the drawwith'a cord running up over a guide-pulley,-
