\VILLIAM R. BOIVMAN, OF DANVILLE, KENTUCKY CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 329,262, dated October 27, 1885.

Application filed August 31, 1885 To all whom, it may concern.-

Be it known that I, WILLIAM R. BOWMAN, a citizen of the United States, residing at Danville, in the county of Boyle and State of Kentucky, have invented certain new and useful Improvements in Oar-Couplings, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in car-couplers, and is designed to produce an automatic device for dropping the pin in the link and for retaining the link at any elevation, that it may properly enter the drawhead of the succeeding car,whether it be relatively high or low.

In describing the device reference is had to the annexed drawings, in which Figure 1 rep resents a side elevation and section of contiguous draw-heads; Fig. 2, a plan View of one of the draw-heads; Fig. 3, a side elevation with a portion sectioned; Fig. 4, details of the pinholder.

The draw-heads A are of any approved construction. Near the mouth, and as low as can be conveniently placed to properly journal, is a transverse shaft, B, both ends being squared or similarly formed, as shown at E. On this shaft, as a pivot, rests the slotted ends 0 of a frame, D, projecting in front and across the mouth of the said draw-head. The slots in the ends 0 are for the greater part of their length considerably wider than the diameter of the said shaft B, but have a continuation, F, that fits snugly over the square portion E. On one end of the shaft, beyond the frame, is a ratchet-wheel, G, with which a pawl, H, pivoted to the draw-head, engages. On either end of the shaft is an operating-handle, I. By engaging the slot continuation F over the shaft it is evident that as the latter is turned the frame will be carried with it, and as it rises will engage with the link K, and elevate it to any desired angle to correspond to'the height of the draw-head in the car to which it is to be coupled. This is shown in dotted lines, Fig. 3. The ratchet holds the frame in place. WVhen the cars come together, the drawhead of the car not carrying the link will hit the frame and drive it backward after the end of the link has engaged in the mouth of the said draw-head, and the frame will fall to the Serial No.175,755. (N0 model.)

I pendent position shown in Fig. 3, the enlarged portion of the slot permitting such movement. In order that the coupling may be automatic, the draw-head is slotted to the rear of the pinhole on top, as at L, in which rests one end of a curved arm, M, the upper projecting portion of which is provided with holes N and a pin, 0, by means of which the extent of the travel of said arm M is regulated to suit different draw'heads. The end of the arm M, resting within the draw-head, is enlarged, as at P, and carries rollers B, so that the friction may be reduced as much as possible. On the enlarged end P rests the pin S. As the link engages with the end of the arm, it pushes it to the rear, the curved portion passing through the slot, and the pin falls within said link, thus automatically performing the operation of coupling. Each draw head is provided with the link-elevator and the pin-support.

It is evident that a clamping-nut may be used in place of the pawl and ratchet.

I claim- 1. In a car-coupler, a link-support consisting of a transverse shaft with squared ends and carrying a handle and ratchet-whcel, and a frame with slotted ends surrounding the shaft, said ends having a contracted continuation, substantially as and for the purpose specified.

2. In a car-coupler, a pin-support consisting of a curved arm with adjustable stops at one end and an enlargement and frictioirrollers at the other end, said arm resting within the draw-head, and having an end passing through a slot therein, substantially as and for the purpose specified.

3. In a car-coupler, the combination, with a draw-head, of a link-support consisting of a frame with slotted ends having contracted continuations and a transverse shaft supporting the same, and a pin-support consisting of a curved arm with an adjustable stop and friction-rollers, the whole arranged substantially as and for the purpose specified.

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

IVILLIAM R. BOWMAN.
