CAR-COUPLING.

:EPECIFICATION forming part of Letters Patent No. 362,996, dated May 17, 1887.

Application filed February 3, 1887. Serial No. 226.3%.

To all whom, it may concern:

Be it known that 1, JOHN RAWLES, a resident of Macomb, in the county ofMcDonough and State of Illinois, haveinventcd a new and useful Improvementin Oar-Couplings, of which the following specification will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked IO thereon.

This invention has for its obj eet the construction of a safety ear-coupling especially adapted to freightcars, and that is simple in construction, durable and very efficient in pperation,

which does not endanger the life of the operator, and its novelty will be fully set forth in the following specification and pointed out in the claims.

In the drawings, Figure 1 is a perspective view of the coupling attached to the car-body. Fig. 2 is a top View of the drawhead detached. Fig. 3 is a longitudinal elevation of Fig. 2, taken in center, showing the inner construction of the drawhead and coupling-pins.

Similar letters indicate like parts in each figure, in which- A represents the car-body. 13 represents the draw-head, constructed with upper and lower jaws, the upper jaw forming guides and a rest 0 for the coupling-pins i'ii. The lowerjaw is constructed with suflicient strength to receive the shock produced when the cars come together when in the act of coupling.

On each side of the draw-head B are formed 3 5 ears 8 s, in which are fitted the rear ends of the coupling-elevis O. The bolt 1. passes through the ears and through the ends of the couplingelevis and draw-head. (See Fig. 2.) The drawhead is constructed with three pin-holes for 40 couplingpins. In the rear of the center hole is a hole for the gravity-pin J. (See Figs. 2 and 3.)

The conpliugpins i t t are connected together at the top by means of the boltK. They fit loosely on said bolt, so that each pin sustains an equal amount of the draft. In the rear of the center pin and connected therewith is aloosely-pivoted gravity-pin, J. (SeeFig. 8.) This gravity-pin is about one-third longer than the coupling-pins i t This gravity-pin is arranged so that the lower end extends back out (No model.)

of plumb when down, as shown in Fig. 3, and

its purpose is, when the pins i 17 i are raised up, as shown in dotted lines in Fig. 3, to (by its own gravity) pass into and rest in the 0011- cave seat I (see Fig. 3,) and hold the pins iii up out of the way when the linker couplingclevis O is entering between the jawsof the draw-head, and when the link or coupling clevis presses back against the gravitypin it forces it out of the concave seat P. Then, by their own weight, the pins t i t and gravity-pin J drop down to their shown position in Fig. 3.

The coupling-pins 2 i i and gravity-pin J are all operated by means of the shaft 10, which is 6 attached by suitable bearing to the car-body, and to which are firmlyattaehed the arms a a, which, by means of short chains, are attached to each end of the bolt K. (See Fig. 1 Each end of the shaft 10 is bent at right angles to form handles a a. Attached to the lelt arm a is an upright rod, 7), which extends to the top of the car-body with suitable hand-hold, so that the operator can operate the coupling pins without danger to life from the top of 7 the car.

The shaft Z extends across the ear-body, and is constructed and attached thereto the same as the shalt '10, and has firmly attached to it the arms lb, which extend outward and two or three inches beyond the pivot-bolt i, one on each side of the draw-head, (the right arm not shown.) These arms, by means of short chains, are connected to the pins 9 g on the couplingclcvis C. On the left arm is attached an up- 8 right red, I), which extends to the top of the car with suitable hand-hold. This shalt Z, with its appliances, is for the purpose of operating the COllPllllg-ClGVlS O by raising it up to its shown position in Fig. 3, which can be done either from the top of the ear or at either side without danger to life.

Operation: The operation of this car-coupling is in the very extreme of simplicity. The operator can either from the top of the car or the sides operate the coupling without being L exposed to danger. If the operator is on top of the car and wishes to couple, he first sets the coupling-pins i t t by grasping the upright red I), that is attached to the arm a on the shaft I00 10, and draws up the pins until the gravitypin J passes into the concave seat P, which movement will hold up the coupling-pins z i i, as shown in dotted lines in Fig. 3. Then, by means of the rod 1), attached to the arm h on the shaftl, he can raise up the coupling-clevis O to its shown position in Fig. 3. The outer end of the arm h extends out beyond the pivot-bolt t, and by means of short chains draws the eoupling-clevis 0 forward sufficient to pass the center of the pivot-bolt t. The clevis O is then raised up easily, and when the cars come together the coupling-clevis Ostrikes the gravity-pin J and presses it back out of the concave seat 1?, which causes all the pins to drop together and couple the cars, and to uncouple the pins i i i are raised up as before, and when the cars are apart the couplingclevis 0 assumes the position shown in Fig. 1. WVhen coupling or uncoupling at either side of the car, the handles n n on the shaft 20 and the handles e e on the shaft Z are used to operate the coupling devices the same as above described. This coupling can be coupled to any of the old-style draw-heads by using a common link.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, 1's

1. In a car-coupling, the draw-head B, having an upper and lower jaw, and provided with ears 3 s, in combination with the couplingclevis 0, having pins 9 g, and secured to the draw-head B by means of the bolt 1, and shaft Z, having suitable handles at each end, and arms h and upright rod b, attached substantially as shown and described, for the purpose specified.

2. In a car-coupling, the draw-head B, constructed with an upper and lowerjaw and con cave seat P, in combination with a series of coupling-pins, t i t, loosely attached together by means of the bolt K, the gravity-pin J, pivoted to and in the rear of the center couplingpin 1', the projecting arms a a, rock-shaft w,

and upright rod b, substantially as shown, and

for the purpose specified. I
