.To all whom, t may concern:

Be it known that 1, DANIEL R. JosLYN, a citizen of the United States, residing at Gurdon, in the county of Clark and State of Arkansas,have invented a new and useful Car- Coupling, of which the following is a specitication.

The invention relates to improvements in car couplings.

The object of the present invention is to improve the construction of car couplings, and to provide a simple and eiiicient one capable of automatic coupling and adapted to be readily uncoupled without going between cars.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings: Figure 1 is a perspective view of a car coupling constructed in accordance with this invention and shown applied to a car. Fig.2 is a horizontal sectional view of two draw/heads coupled. Fig. 3 is a transverse sectional view. Fig. 4 is a detail perspective view of the pivoted jaw. Fig. 5 is a detail View of the unlocking lever.

Like numerals of reference indicate correspondin g parts in all the figures of the drawings.

1 designates a draw-head, having forwardly and outwardly projecting sides 2 and 3, forming an intermediate vertical opening. The side 2 extends outward beyond the other side 3, and is provided at its inner face with a cavity 4, and arranged adjacent to the latter is a pivoted jaw 5, adapted to engage a similar jaw of a corresponding draw-head, and to be swung backward from the intervening space between the sides 2 and 3, into the cavity of the main projecting side 2, for uncoupling.

The pivoted jaw is provided,at its inner end, with a vertical perforation or eye G, through which passes a vertical pin 7, arranged in registering perforations of the draw-head; and at its inner side the pivoted jaw is provided with verticallyaligned eyes or openings 8, receiving a vertical pin 9, which fulcrnms a horizontally-disposed unlocking lever 10, in a slot or opening 11 of the pivoted jaw. The horizontally-disposed unlocking lever is sulostan1 tially segmental, and it has a straight outer edge 12, arranged flush with the outer face of the pivoted jaw, when the latteris in position for coupling.

The inner end of the horizontally-disposed unlocking lever is provided with a perforation, and is connected by a short horizontal bar 13 with an upward-extending arm 14, of a hell-crank lever 15, which extends beneath the draw-head transversely thereof. The inner end of the short horizon tal har is provided with a depending pin 16, fitting in the perforation of the unlocking lever, and preferably formed integral therewith. The adjacent side of the draw-head is provided with an opening 17 through which passes the horizontal bar; and the outer end of the latter is perforated and receives a horizontally-disposed pin 1S of the arm 14 of the hell-crank lever.

The bell-crank lever is fulcrumed adjacent to its angle in a slot at the bottom of the drawhead, and it is connected with an arm 19, of a rock-shaft 20, which is j ournaled in suitable bearings of a car 2l, and terminates at its outer end in a handle. The lower portion of the bell-crank operating lever is sufficiently heavy to hold the upward-extending arm 14E against the adjacent side of the draw-head, to maintain the pivoted jaw in proper position for automatic coupling, and for holding the same in its locked position when coupled. IVhen the lower portion of the operating lever is swung upward, by means of the rock-shaft, the upward-extending arm 14. is moved outward to draw the pivoted jaw hack from the vertical opening of the draw-head, into the cavity of the-main projecting portion or side 2; and this sanne operation simultaneously throws the unlocking lever outward or forward toward the intervening opening between the sides 2 and 3 of the draw-head, to force the hook or shouldered portion of the engaging pivoted jaw out of engagement, to render the operation ot' uncoupling positive. As soon as the rock-shaft is released, the lower portion of the bell-crank lever Will fall and return the pivoted jaw to its locked position, and will normally maintain the saine in that position for automatic coupling.

The rock-shaft may he arranged to enable the operation of uncoupling to be performed pin perforation 22, and it has a link cavity 23, to enable the draw-head to be'coupled with carsr employing the ordinary pin-andlink car coupling, or the like.

When two cars come together for coupling, 1o the pivoted jaws yield sufficiently to pass each other, and to cause their shoulders to engage each other automatically, whereby the operation of couplingis automatic. It will also be apparent that the operation of uncoupling 'I 5 maybe performed withoutgoingbetween cars.

Changes in the form, proportion, and the minor details of construction. may be resorted to without departing from the principle or sacrificing any of the advantages of this inzo vention.

l. In a car coupling, the combination of a draw-head, a horizontal swinging jaw pivotally mounted on the draw-head and provided with a longitudinal slot, an unlocking lever arranged in said slot and fulcrumed on and carried by the jaw and arranged to lie iiush with the engaging side of the same when the jaw is coupled, and means for simultaneously 3o swinging the jaw backward and throwing the unlocking leveroutward, substantially as described.

2. In a car coupling, the combination of a draw-head, a horizont-ally swinging j aw pivotally mounted on the draw-head, an uncoupling lever fnlcrumed on and carried by the jaw and arranged to lie flush with the engaging side of the same and adapted to be swung outward to disengage a corresponding jaw from the said jaw, a bar connected with the unconpling lever, and means for actuat ing the bar, whereby the jaw is swung back and the uncoupling lever is simultaneously operated, substantially as described.

3. In a car coupling, the combination of a draw-head provided with outward-extending sides forming an intervening space, one of the sides being provided with a recess or cavity, a pivoted jaw mounted in the draw-head at the space between the sides thereof and arranged to swing backward into the recess or cavity in nncoupling and provided with a horizontal slot, a horizontally-disposed unlocking lever fulcrumed intermediate. of its ends in said slot, a bell crank lever fulcrumed at thebottom of the draw-head and located on the exterior thereof and having an upward-extending arm arranged at one side of the draw-head, and a horizontal bar connecting the 'upward-extending arm of the bell-crank lever with the unlocking lever and passing through the adjacent side of the draw-head, substantially as, described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
