JOEL COLE, OF ARKANSAS CITY, AND JOEL R'. COLE, Ol" WINFIELD, KANSAS.

AIR-B RAICE C OUPLIN G.

Applicatior filer] To all who'mfit may concern;

Be it known thatJonL H. COLE and JOEL li. COLE, citizens of the United States, residing lat Arkansas City, in the county'oi Cowley'and State of Kansas, and Winiield, in the county of Cowley and State of Kansas, have invented certain new and useful. lmprovements in Air-Brake Couplers, ol" which the following is a speciiication.

This invention relates to railway apparatus, and more .particularly to couplers for airbrake pipes, and has for an object to proyide. a coupler 'capable of automatic locking en gagement with its co-engaging coupler and thus obviate manual assistance.

A further object of this invention is to provide means whereby such couplers may be adjusted whereby each coupler may be held in alinement for eo-engaging its mating coupler.

Other objects and advantages will be apparent from the following description and it will be understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

ln the drawings forming a portion ol this specification, and in which like numerals of reference indicate similar parts in the several views, Figure l is a top plan view of the meeting ends of two railway cars showing the application of my invention thereto, F ig. 2 is a horizontal sectional view through the couplers, F'g.' 3 is a cross sectional view on the line 3-3 of Fig. 2, Fig. l is a perspectivev view of one lol" the couplers, Fig. 5 is a perspeetive view of theattaching member for each coupler.

Referring now more particularly to the drawings, there is shown a portion of two cars A. and B respectively. Each ear is provided with. my improved coupler 10, and as the construction of the members for each ear is identical, it is thought that a description of one wil sulilee for both. Each car is provided with a metallic plate 11 disposed be.- neath 4each end of the car adjacent the usual draw-bar, and this plate has its horizontally disposed portion bolted to the under side oi each ear, as shown at 12. The plate 1.1. is )rm-:ded with longitudinally disposed spaced flanges 13, lor a purpose to be hereinafter described. A ieaf-spring 14 is provided for each plate 1 1 and this spring has a portion ex Specification of Letters Patent.

tending beneath the plate, as shown, and this portion ofthe spring is pivoted for horizontal movement as shown at 15. Each spring outwardly of the pivotal point is extended downwardly as shown at 1,6 then curved as a-t 1.7, and then extended upwardly in spaced relation to the portion 16, shown at 18. -The spring' at the upper endetl the portion 18 is underside of the. spring, as shown.

lllaeh coupler 1() consists ol a vertieally exteiiding plate 24/ comprising a portion 25 arranged for engagement with the portion 2() i the spring, and this plate.A has its upper and. lower edges flared toward. theportion 25 to provide an enlarged portion 26, and from this portion the plate is provided with a portion 27 which terminates at its out-er end to a point 28. The plate 24 is provided upon one side with a socket member 29 comprising vupper and lower walls 30 and 31 respectively and a connecting side wall The socket member is provided with an enlarged Outer end 33, and at the inner end the member is reduced as shown at .34. The outer edge of each wall of the socket member beveled as shown at The lsocket member is preferably located with its inner end adja-v cent the portion 25 of the plate 24', and with its other portion adjacent theouter end of the enlargement 26. Upon the plate 24 opposite the socket member 4there is.

provided. a socket engaging member 36 oonsist-ing ola horizontally'disposed plate 37 which has its outer edge tapered to a point 3N The plate 37 is provided with longitudinally disposed wear strips 3) and 4() located upon the upper and lower side ol the pl ate 37 at the outer edge thereof'. The plate 37 is tapered at its outer edge as shown l'or en gage ment with the. side wall 32 ol" its cri-engaging socket. Each plate 24 is provided with an inwardly directed nipple 41 for attachment of the train, line hose 42. The nipple 41 has y1 oo other, pivoted springsfor yieldingly its inner end disposed in a horizontal passage 43 in the plate 24 and at the opposite side of the plate from the nipple, lthe passage is enlarged as shown at44, and is thus arranged to receive a rubber washer 45, i

It will of course be understood that each coupler for the ends of adjoining ears is arranged with its vparts oppositely disposed, that is to say the coupling member of one car will be arranged to engage. the socket of its co-engaging coupler. i y

.By use of a coupler of this character it will De seen that if an attempt should be made to uncouple the cars while the train is in motion the springs would immediately return each member of the coupler to its original position, and thus iobviate trainmen re-coupling the members which would of c'ourse result in delay of the train. The use of the springs serves to provide a coupler which will be operable at all times, and by the provision of the adjusting screws for each spring it will be seen that each coupler may accurately set for co-engagement with each other.

What is-claimed is:

1. A coupler of the class described comrising coengaging members, each 'meinberiaving oppositely disposed sockets, means carried by each member for engagement-in the sockets, air line connections carried by each member and communicating with each supporty seaoee ing said members, and adjusting scre -s engaged 'with said springs.

2. .A coupler ol" tl'ie class prising co engaging coupling member'- springs carried by said members,A attaching plates, and adjusting screws carried by said plates and engaged with said springs. v

3. The combination with a car, of a plate carried thereby, a spring pivotally mounted upon the under side of said late, and air brake coupling section carried by said spring, and screws carried by said plate and engaged with the spring for movement of the coupling section in a horizontatplane.

4. The combination with a ca r, of a plate carried thereby, a spring piyotally connected. With the under side of the plate, a coupling member carried by said sl'iring, a socket member carried by said coupling member, air line connections carried by said member, a socket-engaging member carried by said coupling member and located outwardly bf the socket member, and means carried by described comY said plate for adjusting said spring in a liori zontal plane.

In testimony whereof we ailix our .signa tures, in presenceof two Witnesses.
