CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 338,297, dated March 23, 1886` Application filed January 5, 1886. Serial No. 187,646.

To all whom t may concern.-

Be it known that I, WILLIAM POWELL, a citizen ofthe United Statesresiding at Oneida, in the county of Knox and State of Illinois, have invented certain new and useful Improvements in Railway Gar Couplings, of which the following is a specication.

My invention relates to a car-coupling of the class in which a draw-head, pin, and link ofthe ordinary form are employed; and the irnprovement consists in providing novel means for supporting the pin and link in position to properly enter the draw-head and couple or be coupled together, either automatically or by means of instrumentalities operative by hand either from the ground or irom the top ofthe car, the link-and-pin supporting devices being constructed to adapt themselves to the varying positions of an ordinary yielding spring draw-head.

In the accompanying drawings, Figure 1 is an end elevation of a car body and coupling with a portion of the body and the bottom of the draw-head broken away; Fig. 2, avertical sectional elevation in the line x m in Fig. 1, showing the coupling and a fragmental portion of the car-body; Fig. 3, a side elevation of one end' of a box-car, showing the levers and arms for supporting the pin and link in their lowered positions by full lines and in their raised position by dotted lines.

The body A of the box-car is provided with the usual Hoor-sills, A', and end timbers, A2, which support a draw-head, B, secured to a draw-bar, B', in a well-known manner to admit of its limited longitudinal or yielding movement. rlhis yielding movement of the draw-head is effected in this instance by means of coiled springs b b', which encircle the drawbar and exert themselves uponend blocks, b2 b3, through which the draw-bar passes, one of said blocks, b2, being securely fixed to the sills of the car, and the other block, b3, being free to move with the draw-bar.

The draw-head Bis supported and has a limited endwise movement within a box or bumperplate, C, secured to the end timbers of the car.

The draw-head B is formed with the usual hollow bell-shaped body to readily receive the link of an approaching car. The draw-head (No model.)

is also provided with coupling-pin holes b4, formed in both the top and bottom walls of the coupling-head, and with a link-lifter pinhole, I, formed in the said bottom wall slightly in advance of the lower coupling-pin hole, b4.

rPhe coupling-pin D is supported upon the end of an arm, E, secured to a rock-shaft, F, supported by bearingsf in a horizontal position above the draw-head, and hand-levers G G', secured to the respective ends of the rock-shaft F, provide simple and effective means for rocking the shaft andlil'ting the coupling-pin out ot'and allowing it to drop into the draw lhead. The lever G is arranged upon one side of the car and the lever G' upon the other side of the car. These levers are of unequal lengths. The shorter lever, G, permits the rook-shaft F to be operated from the ground, and the longer lever, G', extends to the top of the car, and admits of its being reached and operated from the top of the car. A segment-plate, H, is secured to the body of the car, and is in this instance formed of a slotted or double-plated segment, h 7L', between which the lever G' passes, and is held in any required position by the frictionalcontact of a spring-plate, g, secured to the said lever G', to bear against the inner side of one of the segments h h', and thus hold the lever with a yielding pressure against the other segment, in whatsoever position the lever may be placed, until it is pulled down by hand or jarred down by the shock of an abutting car or train.

The middle portion of the rock-shaft F is attened at f to receive the mortised end of a tubular arm, E', into which is fitted an end- Wise-moving pin or arm, E, which serves to support the coupling-pin. A coiled spring, e, surrounds the pin E inside of the tubular arm, and a screw-cap, e', threaded to engage with an external thread upon the tubular arm, incloses the spring and provides-simple means for adjusting the normal length of the arm as well as the tension of the spring.

An open link, D', connects the end of the arm with .the head of the coupling-pin and permits the latter to be readily removedfrom the pin or replaced. Bearing-blocks f2, secured to the car to it close upon the opposite sides of the tubular arm E', support the midlle portion of the shaft and hold the said arm accurately in position to lift and drop vthe pin into the holes in the draw-head. A similar system of rock-shaft, l, link-lifter arm K, pin l?, and levers M M are employed to support and guide the link N of a coupling into the draw-head of an approaching car. The handlevers M M' are of unequal lengths, and are arranged correspondingly with the levers Gr G', above described, in order that each of the rock-shafts may be simultaneously operated from either the ground or the top of the car, and asegment rock-plate, O, secured to the side of the car 4below lthe segmentplates H, above described, serves to securely hold the lever M in any required position. A spring-pawl, in., in this instance engages with the teeth of lhe rock-bar to secure the lever in a fixed position, which can be removed only by hand and by the following` means: A handle, fm', pivoted to tlielever M immediately above the segment rock-plate O, and a similar handle, m, pivoted to the upper extremity oi' the lever, both of said handles being connected to the pawl by links or rods m in a well-known manner, will provide means for lifting the pawl from the rock-bar either from the ground or from the top of the car upon one side thereof, and a pull-rod, m, held in eye-staples m5, is arranged across the end of the car, and is connected by a bell-crank lever, m, and link m7 with the spring-pawl m, whereby the latter may be disengaged from the segment-rack by a person from the opposite side of the car when it is desired to rock the shaft I and operate the coupling-link supported by means of the lever M.

The link -lifter arm K is similar to but somewhat longer than the arm E, and is formed or' a tubular section, K, secured by a mortised end to a flattened part of the rock-shaft I, and receives the endwise-moving pin or arm K and coiled spring K, which are held and adj usted in said tubular section by means of a screw-cap, K3, iitted upon the tubular section K. The outerend of the arm K is jointed to a link-lifter pin, I), which is supported in and passes through the hole b5 in the draw-head above described, and in position to lift the link from the position shown by full lines into the position shown by dotted lines in Fig. 2.

' he devices herein described operate in the following manner: When the link is to be lifted to enter the draw-head of an approaching car, the hand-lever M or M may be operated after disengaging the spring-pawl from the segment-rack, and the lever placed and locked in position to hold the link to the required height. 'Ihe hand-levers G G of the approaching car are drawn back to the position shown by dotted lines in Fig. 3, with the coupling-pin lifted and inclined backwardly and partly supported or propped up by the Walls of the upper pin-hole, b4, in the drawhead, and partly supported by the springpressure of the lever upon the segment-plate H. Vhen the draw-head or bumpers of the cars come together, the shock of the collision will jar down the pin,and throw the lever for- Ward with sufficient force to overcome the frictional contact of the spring upon the segment-plate, and thus permit the pinto quickly and securely drop into the link and seat itself into the holes b4 of the draw-head,to completely couple the cars together without other attention and without danger to the operator.

The spring-connections and eXtensible sections of the coupling-pin, arm E, and linklifting arm K will admit of the free endw-ise movement of the draw-head without straining or interfering with the Amechanism for operating the coupling pin and link, and admit of their adjustment to compensate for slight changes of position due to unequal expansion or contraction or wear and tear of material.

I claim as myinvention and desire to secure.
