NPROVBHENT IN CAR-COUPLING.

The Schedule referred to in the Letters Patent and pan c'l' me same.

To all whom t may concern Be it known that we, MANUEL VAN Emme vand DAVID WOOLSEY Woon, of Rome, in the county of Oneida and State of New York, have invented a new and useful Improvement in Car-Coupling; and we do hereby declare that the following is a. full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference beig had to the accompanying drawings forming part of this specification.

Figure 1 is a side sectional view of our improved car-coupling.

Figure 2 is a front elevation, showing the coupling- .hook raised.

Figure 3 is a similar linghook closed.

-ipilnr letters of reference indicate corresponding parte.

Our invention has for ln car-coupling; and

It consists in the construction and combination of parts, as hereinafter more fully described.

A is the bumper-head, which may be seemed to the car B in the ordinary manner.

D is the coupling-hook, which is placed in a slot in the upper side of the bumper-head A.

The coupling-hook is secured to the bumper-head by means of a pivot-pin, d, whichpasses laterally through the bumper-head, and through a longitudinal slot or opening in the coupling-hook, as shown.

its object an improvement 4The slot permtsrof a longitudinal movement of the hook D.

When the coupling-hook D is closed, as shown in 'the drawings, its under surface comes in contact with or meets the surface of the bumper-head, and the meeting surfaces of the coupling-hook and bmnperhead are made in a peculiar form, so as to resist the longitudinal strain of the link C against the coupling hook D. i

lt will be obse'ed that the lower portion e of thc coupling-hook is convex, and fits into a corresponding concave cavity, c', of the bumper-head.

'lhc meeting-surfaces o d form a lock to hold the coupling-hook D, and assist itin resisting any longitudinal strain brought against the hook by the link O.

The longitudinalr resistance of the coupling-hook D is also further assisted by the concave form of the front portion ot' the bumper-head at a', into which surface a of the coupling-hook lits, as shown.

The point of the h ook D enters a shallow recess ibrmed in the bottom or lower side of the month of the bumper-head A, and the forward edge of said elevation, showing the coup-` hook is beveled or rounded oil', so that the enteringlink C, when the cars are run together, may raise the said hook and pass into thc coupling-box.

The shoulder f of the hook D, that the link C rests against in sustaining the draft strain, is inclined or curved, so that the tendency of the draft strain may be to draw the hook downward, and thus hold it securely in place.

l) is a. projection or horn rising trom the surface oi' the interior of the bumper-heini, located a short distance from the roar of the coupling-hook D, when the lat-ter is closed.

The front portion of the horn b is made in concave form, and is intended to receive and resist the push of the link Cgvhen the latter is introduced within the bumper-head.

The concave form of the ern b, when tho link strikes it, prevents the link from rising against and lifting the coupling-hook l). f

Tile rear portion of the coupling-hook D is elongated beyond the pivot-pin d, so as to form a lever, It, against theI under side of which a spring, E, acts in such a manner as to press thc lever hy upward, thereby lorcing and holdingdown the front end of the coupling-hook D, preventingjt from being raised by jarring or jolting, thus forming a security againstaccidental nneoupling.

Thespring E is protected trom injury by the peculiar. formation of the interior ofthe hnnper-head, which forms a covering-shield for the spring l.

To the upper part of the forward end Oi' the honk D is attached the lower end of the short chain l, the upper end of which is pivoted to the inner end Of'thc lever G, which is pivoted to the 4body or platform of the car, and its'outer end extends out into such a position that it 'may be` conveniently reached,

and operated from the side of the car for uncoupling` the cars. e l

The outer part of the lever G passes througla keeper, 1I, attached to the body or platform oi' the car, and which is formed, orwith which is connected, a double catch, I, to hold the lever G, both when the hook D is down and when it is desired to hohl the said hook raised.

J is a lover, the lower cndof which is pivoted to the louter part of the lever G, and which extends up into such a position that it may be reached and operated to uncouple thc cars from the top of the car.

The lever J passesl up through an eye-bolt or keeper attached to the car, to keep the said lever in proper position, and which serves also as a fulcrum to enable the lever G to be detached from the catch I- by means of the said lever J.

We d not vclaim broadly the use f the slotted axis-opening in the draw-hook for the urpose of releving the axis-pin from-strain; but, 4

Having thus described our invention,

We claim as new and' desire to secure by Letters Patent- Y l 1. The bumper-head'A, coilpling-hook D, spring E, coupling-link C, bar I, lever G, and catch I, arranged as shown and described.

2. The cmbnation of the double catch I with the -Ami bar J, lever G, and coupling-hook D, whereby the coupling-hook D may be held in an elevated position, or ,A its undue4 elevation, by combined weight of said bar and lever, be prevented, all constructed' as hereinbefore shown and described MAUEL VAN sLY'Kn.
