CAR-COUPLING.

SPECIFICATION forming part of' Letters Patent No. 321,372, dated June 30,1885,

Application filed April 30, 1885. (No model.)

To @ZZ whom it may concern:

Bc it known that l, J osnrH N. LEROUX, a citizen ofthe United States, residing at Toledo, in theeountyof Lucas and State of Ohio, have invented certain new and useful Improvements in Gar Couplings, and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to 1o make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which forni a part of this speciicationmrw f.

My invention relates to automatic car-couplings in which a hooked link is engaged by hooks in the draw-head.

The objects of my improvements are, first, to so arrange the hook with reference to the draw-head that the stress exerted on the hook ze shall be sustained by shoulders in the frame of the draw-head over a broad surface in any position the hook may be forced by the pull or jarring of the cars short of its uneoupling position, and at the same time to allow for easily coupling automatically without danger of jamming; second, to provide a means for uncoupliug by hand; third, to provide axnea-ns for automatically holding the link in a horizent-al position for entering the cavity of the 3o opposite draw-head; fourth, in my automatic car-coupling to provide for coupling with a pin and elliptical link, in the usual manner. I attain these objects by the means illustrated in the accompanying drawings, in which* 3.5 Figure l is a top view of the entire drawhead. Fig. 2 is a section through the drawhead,with the movable parts removed. Fig. 3 is a vertical projection of the eoupling,with the side of the draw-head frame removed,

4e showing the hooked link held in position for entering the cavity ofthe opposite draw-head. Fig. 4 is a vertical projection of the coupling, with the side of the draw-head removed,show ing the manner oi' coupling it with the ordinary pin and elliptical link'. Fig. 5 is an iso metric view ofthe couplinghook removed from the draw-head. Fig. 6 is an isometric view of the link used in coupling automatically.

Si milar letters referto similar parts througl1- 5o out the several views.

The hook B is made in the form oi' a cross in its horizontal projection by the shoulders b I), which slide in the slots 7L Il., formed in the frame of the draw-head for that purpose, and is provided with thc slot y, for receiving the pin g, upon which the hook turns, and to pre vent the stress being communicated from the hook to the pin. The faces cr a; of the shoulders Z1 b are formed in the are of a circle in their section parallel to the side of the hook, 6o

y whose center is g. The slots li h in the frame /of the drawhead A are formed to receive the shoulders b b, their forward part forming au arc of a circle whose center is f/, Fig. 2, having the faces of the shoulders V V in the frame A A concave to correspond to the contour of the faces x x of the shoulders Z1 b.

By thus forming the hooks and corresponding slots in the frame of the draw-head A A, the stress upon the hook is transferred by the 7o shoulders bb to the frame of the draw-head at 'u o in any position of the hook until it is drawn clear of the frame of the draw-head, and the face YV of the hook B, against which the head of the link strikes for raising the hook in entering the draw-head, can be made rapidly retreating or inclined to the perpendicular, so that the hook can be easily raised by the entering head o of the link L, and thus danger of jamming is avoided. S0

The hook is raised for unc-oupling by the series of connected cranks E D F F D E, forming one bar of iron or other suitable material, as shown in Fig. l, turning on the journals D D. The portion F F is hollowed in the mid- S5 dle and slides forward and back in the slot C C o n the hook B. By turning the crank E, the

hook B is raised, as shown at B in Fig. 3, al-

lowing the link to be withdrawn from the draw-head. The portion D F should be long enough to raise the hook clear of the drawhead without turning it into a position that would prevent the link from returning into the draw-head.

The hook B is preferably held down by a spring, G, but may be forced down by gravity alone.

The hook B is set back in the frame of the draw-head a sufficient distance to allow space ahead of it for coupling in the ordinary way roo by the pin P passing through the holes a a, provided for that purpose, and through the elliptical link L, as shown in Fig. 4, thus admitting of coupling` with the ordinary draw` head.

The hook B, passing down upon the link L, holds itin a horizontal position, ready to enter the cavity of the opposite draw-head. The link L is prevented from entering too far into the draw-head by the cross-piece d d, Fig. 6, the ends of which may also be used as handles.

Having fully described myinvention,whatl desire to claim and secure by Letters Patent 1s- 1. The hook B, having the shoulders Z) Z), with faces x x, curved in the arc of a circle, whose center is the point about which the hook turns, and having the surface NV, against which the link strikes in entering the drawhead, rapidly retreating or very nluch inclined to the perpendicular, substantially as shown I and described.

2. The hook B, in combination with the frame A A of the draw-head, having the slots h 7L and shouldersV V, substantially as shown and described.

3. The hook B, having the shoulders b b, inclined face W, and slots y, in combination with the frame of the drawhead A A, having the slots h h and shoulders V V, substantially as and for the purpose described.

4. The hook B, having the shouldersb b, inclined face W, and slot i, lsubstantially as shown and described.

5. The series of connected cranks consisting of the handles E E, journals D D, Working in suitable bearings, and the portion F F, bent as shown in the drawings, working in the slot G C on the hook B, in combination with the hook B, substantially as and for the purpose speciied.

In testimony whereof I affix my signaturein presence of two Witnesses.

JOSEPH N. LEROUX.
