CAR-COUPLING.

SPEGIFICATION forming part of Letters Patent N0. 502,295, dated August 1, 1893.

Application filetl March 27. 1893.

T0 all whom it ma;y concern:

Be it known that I, WILLIAM MOKINNE HALL, a citizen cf the Unitecl Staates, residi1ig ab Victoria, in the county cf Marshall a11d State of Mississippi, have inventcd a certain new, useful, and valuable Improvexnent. in Oar-Oouplers, cf which the following is a full, clear, and exact description.

My invention l:1as relation to car couplers and it consists in the novel construction and arrangement of its parts.

In the accompm'ying drawings:-Figure 1, is a longitudinal sectional view cf a drawhead and link. Fig. 2, is a top view of the drawhead. Fig. 3, is an end view of the drawhead, ancl Figs. 4, 5, and 6, are details of differcnt pa1ts that will be explained;hereinafter.

The object cf my invention is toprovide an automatic coupler that can be operated without the necessity of thc operator going between the cars.

It is dcscribed as follows: It consists cf the drawhead 1, which has in its perpendicular inner sides the horizontal grooves 2, 2. In the top cf the drawhead is cut ehe slot 3, which has at one end the enlargement 4. In tlie said slot 4, is located the post 5, the edges of thc slot entering the reccsses 6, 6, on either side cf the said post. The sliding block 7, is provided 011 eacli longitudinal lower edge with the flanges 8, 8. Said fianges rest in the grooves 2, 2. The block 7, is also provided in its lower front edge with the recess 9. Said recess is preferably V-shaped as shown in Fig. 4. The post 5, is placed in the slot 3, by passing through the enlargcment 4; thcn the plate 10, is sccured over the said enla1gement and tl1e said post is thereby prevented fro1n coming ont.- After the sliding block 7, is placed in the drawheacl the pegs 11, are securedin the grooveS 2, 2, in front cf the said block and thereby the said block is prevented frorn coming out.

In connection with this couplcr a link 12,

sm1 No. 467,762. (N0 model.l

with beveled and converging ends is preferably 1ised, Said link consists cf a solid piece of iron having at each end a perforation 13.

My invention operates as f0llows :The post 5, is pullecl forward which pnshes the sliding block 7, under tl1e pin perforation 14, in the top of the drawhead. Then the link is securcd in the clrawhead of thebacking car and the free end will strike, the inclined surface 15, of the stationary drawhead. The link then passes up and strikes in the recess 9, of the sliding block which pushes the said block and post 5, back, and at the same filme the pin falls 011 the said link, and as the cars pull apart the pin falls through the perforation 13, in the said link. Then the lower end of the pin falls into the socket 16, in the lower part of the drawhead, and tl1e cars are coupled.

In coupling the pin is simply raised by hand 01 by a chain attac'hed to the top there- 6 cf and running to the top cf the car.

Having described my invention, what I claim as new, and desire to secure byLetters Patent, is-

1. A car coupler consisting cf a drawhead having in its inner and perpcndicular sides horizontal grooves, and in its top a suitable slot; a sliding block having suitable flanges adapted to rast in said grooves, and a suitable recess; a sliding post located in said slot and adapted 130 push the sliding block forwar. substantially as sei; forth.

2. In a car coupler having a suitable sliding block, a drawhead having a slot'with an enlargement cut in its top; a sliding post adapt- WILLIAM MCKINNE: HALL. Witn esses:
