CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 481,906, dated August 30, 1 892.

Application filed November 12, 1891. Serial No. 411,718. (No model.)

To all whom, it may concern:

Be it known that we, DELBERT W. J EWELL and GEORGE JEWELL, citizens of the'United States, residing at Alexander, in the county of Genesee and State of New York, have invented a new and useful Car-Coupling, of which the following is a specification.

This invention relates to car-couplings, and more especially to that class thereof known [0 as twin-jaw; and the object of the same is to effect certain improvementsin the catches for the jaws of such couplings.

To this end the invention consists in the construction hereinafter more fully described and claimed, and as illustrated on the two sheets of drawings, Wherein Figure 1 is a general perspective View of the end of a car provided with our improved coupling, the latter being seen as open and viewed slightly from the upper side. Fig. 2 is a plan view of two draw-heads coupled. Fig. 3 is a transverse section through a drawhead in its coupled position. Fig. et'is a similar section showing the catch as having been raised and supported on the lug. Fig. 5 is a horizontal section showing the heel of the wedge as just tripping the pin. Fig. (5 is a horizontal section showing the coupling as locked closed. Fig. 7 is a perspective detail 0 of the jaw inverted. Fig. 8 is a similar view of the catch.

In the accompanying drawings the drawbar 1 is supported in any suitable manner heneath the car-body 2, and at the front end of 5 the draw-bar is the draw-head 3, whose face is approximately U-shaped in plan, coming to a sharp edge 4: at the left side and to a rounded edge 5 at the right side, the latter edge being vertically bifurcated, so as to form ears, between which is pivoted the swinging jaw. This jaw comprises a rounded front end 13, having a horizontal slot 1t,illt61S60ted by a vertical pin-opening 15, whereby the coupling may be connected with another of the ordinary pin-and-link type, and in rear of this front end is a reduced angle 6, mounted in the bifurcation of the rounded end 5 of the draw-head on a vertical pivot-pin 16, the body then extending to the rear in an arm 18, which is adapted to be engaged by acatch. In eyes '7 on the dead-block 8 is mounted an oscillating rod 9, havinga handle 10 at one or both sides of the car-body, and on the rod, at about the center of said body, is a forwardly-projecting crank 11, which is connected by a chain 12 with the said catch, the latter being of the construction hereinafter described.

Coming now to the present invention, the rear end of the arm 18 is provided with an are 20, struck on a circle around the pivotpin 16. The rear lower corner of this are is provided with a recess or cut-away portion 21, opening at the left end of the are and with its inner end at about the center of the arc, and the right end of the arc is provided with a rearwardly-projecting heel 23, all as best seen in Fig. 7.

22 is a pin rising from the bottom of the mouth of the draw-head, and the recess 21 moves over this pin, as seen in Fig. 5, its inner end engaging the pin when the coupling is uncoupled, and thereby preventing a further movement of the jaw.

24: is a V-shaped expansive spring, one of whose feet rests against a lug 25 within the draw-head, while the other foot rests in a notch 26 in the body of the jaw, the tendency of this spring being to hold the jaw open, as seen in Fig. 5. lhe catch above mentioned is a block of iron mounted on a horizontal pivot 30, which stands longitudinal of the draw-head, the body of the catch standingin a transverse slot in said draw-head at about the position shown and carrying at its upper edge a surrounding flange 31, which covers said slot and prevents the entrance of snow and ice or dirt or other substances which would clog the coupling and prevent its proper operation. In the rear face of the body of the catch is a recess 32, in which is pivoted at 33 a pin 34, which rises through the top of the draw-head and is connected with the chain 12 above mentioned. It will be understood that the body of the drawhead is recessed or formed with internal cavities of the proper size and shape to receive the parts above described and permit their proper operation. Within such cavity there rises from the bottom thereof a lug 35 at a point to stand adjacent the rear face of the are 20, and this lug is of such a height that the heel 23 will pass over its upper end.

With this construction the operation of the device is as follows: The parts being in the position shownin Fig. 3, when it is desired to uncouple the device one of the handles 10 is manipulated to raise the crank 11, and this draws on the chain 12 and lifts the catch by its pin 34; but as said pin at its upper end stands a little to the left of the crank-arm 11 when the latter is raised the pin is not only raised, but is also turned on its pivot 33, and by this means the lowerend of the pin is caused to ride up the lug 35 and rest on the upper end thereof, as seen in Fig. 4. The tension on the front end of the jaw or the force of the spring 24 then causes said jaw to swing on its pivot-pin 16, and in doing so the heel 23 pushes the lower end of the pin 84: oil? the lug 85, as seen in Fig. 5, after which the corner 36 of the catch will rest on the upper face of the are 20, and the catch will be supported thereby. The are meanwhile turns until the inner end of its recess 21 strikes the stop-pin 22, which limits the outward movement of the jaw. The coupling is automatic, as in nearly if not all ear-couplings of this character, and the operation thereof is as follows: hen the two draw-heads come together, the jaws turn around their pivot-pins 16 until the arcs 20 pass from beneath the corners 36 of the catches, which were supported thereby, the catches fall, and the jaws are locked. It will be seen that the cars can be uncoupled when at a standstill, because when the catch is raised it is held raised by the pin resting on the lug, and when the cars separate and the jaw opens it pushes the pin cit the lug and places the parts in position to automatically lock the jaw when it is again closed.

The parts of this coupling are of any desired sizes and materials, and considerable change in the details of construction may be made without departing from the spirit of our invention.

In Fig. 1 we have shown an arm 50 depending from the draw-11 ead 3 and turned forward, as at 51, at its lower end, and when two drawheads are coupled and by any accident one of them becomes disconnected from its car and pulls out it is obvious that the front end of its jaw will drop onto the forwardly-bent portion 51 and be sustained thereby. In this manner a draw-head which becomes detach ed is prevented from falling onto the track, whereby it might derail or injure the cars.

hat is claimed as new is 1. In a car-coupling, the combination, with the draw-head and a catch therein, the body of the draw-head having a horizontal cavity and a pin in the bottou thereof, of a jaw mounted on a vertical pivot, an arm projecting from said jaw and moving in the cavity, and a recess in the arm, moving over said pin.

2. In a car-coupling, the combination, with the draw-head having a horizontal cavity and a vertical recess, a lug rising from the bottom of said cavity, a catch mounted on a horizontal pivot in said recess, and a pin pivoted to the catch and adapted to rest on the upper end of the lug when the catch is raised, of a jaw mounted on a vertical pivot, an arm projecting from said jaw and moving in the cavity of the draw-head, the rear end of said arm having an are moving pastsaid lug and pin, and a projection on the face of this arc adapted to strike the pin as the device is uncoupled.

5. In a car-coupling, the combination,with the draw-head having a horizontal cavity and a vertical recess, a lug rising from the bottom of said cavity, a catch mounted on a horizontal pivot in said recess, and a pin pivoted to the catch and adapted to rest on the upper end of the lug when the catch is raised, of a jaw mounted on a vertical pivot, a spring throwing the jaw normally open, a stop limiting its movement, an arm projecting from said jaw and moving in the cavity of the draw-head past said lug and pin, and a projection on the arm adapted to strike the pin as the device is uncoupled.

6. In a car-coupling, the combination, with the draw-head having a horizontal cavity, a lug within the same, and a V-shaped spring, one foot of which bears against the lug, of jaw mounted on a vertical pivot and having a notch in its body, within which the other foot of said spring rest-s, a stop for limitin g the outward movement of the jaw, and a pin pivotally mounted for holding said jaw in closed position.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
