`- ,lliure STATES `PATENT i FFICE@ SAMUEL D. LEE, OF MEGHANICSVILLE, IOVA.

cAR--couPLlNe SPECIFICATION forming part ofLetters Patent No. 295,773, dated March 25, 138e. Application filed January 18, 188:4. (No model.)

To LEZ whom it may concern:

Be it known that I, SAMUEL D. LEE, a citizen of the United States, residing at Mechanicsville, in the county of Cedar and State of Iowa, have invented certain new and useful Improvements in Car-Couplings; and I do hereby 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 make and use the same.

This invention relates to car-couplings of that class `in which the Alink is adapted to be hooked over a projection or head formed upon the draw-head; and its object is to provide a coupling possessing `superior advantages in pointl of simplicity, durability, and general efficiency, and which can be readily and conveniently operated without danger of mashing the hands or otherwise injuring the operator.

In the drawings, Figure 1 is a perspective k view, showingthe end of a ear equipped with my improved coupling. Fig. 2 is a vertical longitudinal sectional view taken through the draw-head. Fig. 3 is avertical transverse sectional view taken on the line :c fr, Fig. 2. Fig. 4 is a detail perspective view of the couplingpin, a portion being broken away to better l j ections a and a?.

show the construction. Fig. 5 is a detail plan View of the coupling-link.

Corresponding parts in the figures are denoted by the same letters of reference.

Referring to the drawings, A designates the draw-head, which is secured to the car in any suitable manner, and is preferably cast from metal, and with all its parts integral. The draw-head is adapted also to form the bumper, and comprises a longitudinal body or main portion, a, from the top of which, at its front end, projects a head or extension, a', in'rear of which is provided another projection, a2, a space, a, being provided between these pro- This space ai receives the coupling-link, and it is lof sufficient length to permit necessary longitudinal play of the link as the draw-heads come together and separate, so that straining of the link is obviated.

Between the projection a2 and the rear end, a4, of the draw-head isprovided a longitudinallyextending groove, c6, having at veach end an auxiliary groove, a7, opening to the side of the draw-head, a guideway, c5, being provided between these auxiliary grooves. Perforations a8 are formed in the proj ections a a2, and the rear end, at, on a plane corresponding to the plane of the groove as. These perforations and the said groove receive the corresponding cylindrical coupling pin or bar, B, which has a longitudinally-sliding movement therein. To facilitate this movement, the perforations and groove are preferably formed on a plane which inclines towardthe rear end of the draw-head. The coupling-pin is provided with a lateral handle, C, which is adapted to engage the auxiliary grooves ci to lock the coupling-pin in the position to whichit is adjusted. This handle is preferably provided with a screw-threaded end, c, which is set in a corresponding recess, a9, in the coupling-pin after the latter has been placed in position.

D is the link, which may be of the usual con- 7o struction, and is provided at each side with a lateral handle, d, by which it can be readily manipulated.

From the foregoing description and annexed drawings, the operation and advantages of my 7 5 invention will be readily understood. To couple, it is only necessary to lift the link by means of one of its handles over the projection a, and then adjust the coupling-pin forward by means of its handle, when the latter will drop of its own gravity into the foremost groove, al, and the coupling-pin will be looked in this position. Ihe uncoupling is effected by a reverse movement, and it will-be apparent that the operation can be easily effected without endangering the operator. The general safety of my improved coupling and its durability will also be apparent.

I claim as my inventionl. The combination, with a draw-head having top projections, and provided with guideperforations and with laterally extending grooves, ofa longitudinal coupling-pin adapted to slide longitudinally in the guide-perforations,` and to turn therein, so as to engage the lateral grooves, substantially as and for the purpose set forth.

2. The combination, with a draw-head having two top projections provided with perforations on an inclined plane, of a longitudinal Ioo coupling-pin sliding in these perforations and retained thereby, substantially as set forth.

3. rlhe combination, with a draw-head having top projections, and a guideway terminating in lateral grooves, of a longitudinally-sliding coupling-pin engaging the projections, and provided with a lateral handle engaging said grooves, substantially as and for the purpose set forth.

4. A oar-coupling embodying the dra\v-head, provided with the front projection or head, the proj eetion 'in rear of this, the groove having the lateral end grooves and the intermediate guideway, and the longitudinal coupling-pin sliding in the proj eotions and provided With the lateral handle, substantially as set forth.

5. The combination, with a draw-head having the front head or projection, the projection in rear thereof, the rear Wall, the guide- SAMUEL D. LEE.`
