CAR-COUPLING.

SPECIFICATION forming part Of Letters Patent N0. 400,617, dated April 2, 1889.

Application filed June 13, 1888- Serial No. 277,155- (NO model.)

Toall whom it may concern: I

Be it known that we, ISAAC LAYFITTE WHIDnoN and JULIAN SEAYBAsHAw, both of Ghipley,.in the county of Washington and State of Florida, have invented a new and Improved Oar-Ooupling, of which the following is a full, clear, and exact description.

This invention relates to car-couplings, and has for its object to provide a car-coupling which will couple automatically, and which may be uncoupled from either side of a car.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views. I

Figure 1 is a plan view of the invention n coupled position. Fig. 2 is a plan view, 1n horizontal section, showing coupled position. Fig. 3 is avertical section on the line mm, Fig. 1; and Fig. 4 is a vertical section on the line 1 y, Fig. 1.

In carrying out this invention, draw-heads 1 are provided, formed with inclined overlapping portions 2, having chambers 3, in which are located the rotary and Sliding catches 4. The latter are mounted on vertical pins 5, having their ends projecting through curved slots 6 in the top and bottom of the inclined portions 2, the upper ends being provided with arms 7, pivotally connected by rods 8 with crank-rods 9, mounted in bearings 10 on the ends of a car, and having crank-handles 11 at the sides of the car, with weighted ends 12. The catches 4 are formed with the engaging-shoulders 13 and the oval portions 14,with a rearwardly-extending projection, 15, located within curved hook-shaped springs 16, secured By means of this con-- struction it will be seen that as the inclined portions 2 of the draw-heads approach and slide over each other the outer side of the oval portions 14 will bear against and slide over each other, thereby pressing back the catches 4, the ends of the pins 5 moving back inthe curved slots 6, and upon the shoulders 13 passing each other the catches 4 Will be thrown forward by the springs 16 and into engagement.

To eifect the uncoupling, the catches 4 are disengaged by rotating a crank-rod, 9, which In order to use the draw-heads l'with an ordinary coupling-pinand link, a hole, 19, is formed in the end of the draw-heads, extending through recesses 20, for the admission of a link.

To allow for wear of the parts, the rods 8 are formed in two parts, connected by a turnbuckle, 21. r

In order to use the coupling with high and low cars where the portions 2 are located at unequal heights, the latter are formed with vertical recesses or grooves 22 in their overlapping surfaces opposite to the catches 4, thereby permitting the catches 4, owing to their height, to engage each other, whether their upper or lower surfaces are in a higher or lower plane.

- It will thus be seen that by means of this invention astrong and secure couplingis provided, which is readily and automatically coupled and which may be easily uncoupled from either side of a car.

Having thus described our invention, we claimas new and desire to secure by Letters Patent- 1. In a car-coupling, the vcombination, with a draw-head, of a spring-actuated catch slots 6 in the top and bottom of draw-heads 1, and formed with shoulders 13, oval portion 14, and projection 15, the reacting-spring 16, extending over the side of projection and oval portion 14, and the crank-rods 9, with weighted crank-handles 11 at the sides of a car, and rods 8 connecting crank-rods 9 with arms 7 on pins 5, substantially as described.

4. In a oar-coupling, the draw-heads 1, formed with recess and hole 19 at their outer ends, and with the overlapping inclined portions 2, having recesses 3, the roiarycatches 4, mounted on pins 5,having their ends located in curved slots 6 in the top and bottom of draw-head 1, and formed With shoulder 13, oval portion 14, and projection 15, the reacting-springs 16, extending over the side of projection 15 and oval portion 11, the rods 8,- conneoting arm 7 on pins 5 with crank-rods 9, and the operating-rod 17, connected with cranlerod 9 and extending to the top of a car, substantially as described.

5. in a car-coupling, the draw-heads 1, form ed with the inclined overlapping portions 2, having vertical recesses 22 in their abutting surfaces, recesses 3,with rotary catches 4, mounted on pins 5, having their ends located in inclined slots (3 in the top and bottom of drawheads 1, and formed with shoulders 13, oval portion 1 1, and projection 15, the reacting-spring 16, extending over the side of projection 15 and oval portion 14, and the crank-rods 9, with Weighted crank-handles 11 at the sides of the car, and rods 8, connecting crank-rods 9with arms 7 on pins 5, substantially as shown and described.
