To all whom 'it may concern:

Be it known that l, BENJAMIN BANYAY, a subject of Hungary, residing'at Newark, 1n the countyof Licking and State of Ohio, have invented certain new and useful lmprovementsin Draft-Gear and' Couplings, of which the following isv a specification.

Myinventi'on relates to a draft gear'and coupling primarily designed for use upon street cars though it may be used upon rail waycars, if desired.

The object of the invention is to provide a device of .this character comprising a buffer for the device as a whole, means tend-ing to hold the draw bar in longitudinal alinement lW1th the bodyof the car, and means controllable either` from the ground or from the front platform of the car, said means being 4 adapted to release the locking knucklevof the' coupling.

Further objects and advantages of the `-invention will be set forth in the detailed de-l scription which now follows. Inthe accom anying drawings, Figure .1 1s a plan view o the front end of a street car brokenaway to ,illustrate the parts located there beneath, Fig.- 2 is a view partly in vertical section and partly `in side elevation of thefront end of said platform, Fig. 3 is an enlarged horizontall section through the front end. of the `draw bar, Fig. 4 is a horizontal section through the'rear end. of the draw bar, and Fig. 5 is a vertical sectionl through the front end of the draw bar.

Like numerals designate corresponding parts in all of the figures of the drawing.

Referring t'o the drawings, the numeral 5 designates a portion of the floor of the front platform of. a street car, said floor being supported upon -sills 6.4 Transverse channel lrons 7 are secured to the under side of these sills -by bcltsand these channel virons in turn support a draft buffer 9. A spring 10 is located in and forms .a part of the buffer 9,

' said spring receiving the rear thrust of a king bolt 11.

mounted upon this king bolt and antifriction' The draw bar -12' "is pivotally devices 13 are inte osed between the draw bar and the upper ace of draw bar 12 swings upon saiddraw bar being out out as at 15 to form a recess for thel reception of the outer edge of an. arcuate-plate 16, said plate being carried b the front edge of the platform. This p ate serves as a guide and support for the outer end of the'draw bar. Transverse bars tudinal movement with relation thereto. spring is coiled about the shaft 18 in the a collar 14. TheA the king boltl 11,.

18, byt

17, 17 extend between the sills 6 and said bars carrying bearing blocks 8, 8 of a shaft 18. A bevel inion 19 is splined as at 19 upon this sha t in such manner that it will rotate therewith though capable of longirear of the bevel pinion 19 and bears between said pinion and a collar 21. This spring serves to l.maintain the bevel pinion 19 always in mesh with a bevel pinion 22 which is fast with a transverse arm 23and is mounted to rotate freely upon the king bolt 11. The shaft 18 has a universal connection 24 with a shaft 25 the outer end of this shaft passing through the front of the platform and having a hand lever 26 secured thereon. By means of this lever the operator standing u on the ground may impart a partial rotat1on,to the shaft 25 in either direction for a l purpose lhereinafter described.

A hand Wheel- 27 is fast upon a stem 28 which passes through the platform and which has a bevel pinion 29 upon its lower' end. This bevel inion meshes with a bevel inion 30 of the s aft 25. It will therefore e seen that movement of the hand wheel will impart movement to the shaft25,said

hand `Wheel being accessible to a person standing upon the platform 5.

The draw bar com rises the coupler head .12 and the rearwar y extending U shaped portion 122,' and it is this U vshaped portion through which the king bolt 1 1 passes. The coupler is of the J anney type and com rises the head 12 and the 4movable knuc e `31 which lis pivotally mounted at 32, in the coupler head 12. As is best illustrated in Fig. 3, the knuckle 31 is provided with a tail '33 which is ladapted to be engaged by a latch bolt 34.` This bolt carries a vertically disosed pin 35 at its rear end, said pin traveling 1n a slot 36 of the draw bar. A coil spring 37 bears between Lthe enlarged front portion of the bolt l34 and the collar 38 said collar being fixed within the bore 39 and the reduced rear end of the bolt 34 sliding freely through this collar. The slotted ends 40 of links 41 and 42 engage the upper end of the pin 35 and the rear end of these links are pivotally connected at 43 to the outer ends ofthe transverse arm 23. It will therefore be seen that when a artial rotation is imparted to shaft fie actuation of either the hand lever 26 or the hand wheel 27, ka dpartial rotation will in like manner be imparted to the pinion Iseen that the king bolt 11 has a block 45 22. This will rock the arm 23 in one direc tion or the other, to cause one of the links 41 and 42 to draw the pin 35 rearwardly against the tension of springr 37 and release the tail 3S of knuckle 3l. s soon as this tail is released, a at spring 44v throws the knuckle outwardly to release the couplin The parts so far described re ate to the means for releasingr the coupling from a distant point and for applying a bufing spring to the draw bars as a whole. lhe means for normally holding the ldraw bar in longitudinal alinement wlth the body of the car will now be described.

Referring particularly to Fig. 4, it will be rigidly iixed thereto. Uon opposite sides.: of the king bolt this bloc carries shoulders 46 and 47. A block 48 is mounted upon the rear end of a rod 49, said block having recessed shoulders 50 which lie in engagement with the shoulders 46 and 47 when the draw bar is -in longitudinal alinement with the car. body. The front end ofl the rod 49 is slidably disposed in an opening 51 of the front portion of the draw bar and a comparatively i ieavy spring 52 bears between the end 53 of the draw bar and a collar 54, said collar being threaded upon'the rod 49. It is apparent that by screwing the collar 54, toward'the block 48, the tension of the spring 52 will be decreased, while by "screwing said collar in the opposite direction, the tension of said spring will be increased. It will therefore be seen that if the draw bar be swung bodily in either direction, the spring 52 willl be compressed by reason of one of the shoulders 50 engaging with its corresponding shoulder 46 or 47. Of course there would be no eoml, pression of spring 52 if the block 45 werefree to rotatevaround the kino' bolt l1. In that case all of the parts would remain in just the same relative position. But with the block 45 held against movement and with the il 45 block 48 tending to rotate about the king bolt 1l, it is apparent that said block 48 will be forced forward to thereby compress the spring 52 between the collar 54 and shoulder 53. lf the draw bar be now released, it is apparent `that the spring 52 will serve to return the parts to their former position, that is, said spring will throw the draw bar into llongitudinal alinement with the car bodyF When the knuckle 31 has been o )enedits tail lies against the front face of the atch bolt 34 and a-s opposing ears come together and the knuckle 1s forced inwardly, this tail 83 rides over the front face of' the bolt and forces said bolt inwardly against the tension of s )ring 37 until the parts assume the position shown in Fig. 3.

From the foregoing description it will be seen that sim le and el'licient means are herein provided)for accomplishing the objects of the invention,l but while the elements shown and described are well adapted to serve the purpose for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claim.

Having described my invention, what l claim is:

ln a device of the character describel,the combination with a car body, of a pivot member, a member xed to said pivot member and having shoulders eccentric to said pivot member, a draw bar pivotally mounted upon said pivot member, a member adapted to engage said shoulders and a spring intel'- posed between av portion of the draw bar and said last named member,

In testimony whereof l allx my signature in presence of two witnesses.

BENJAMIN BANYAY.
