NITED STATE/s DAVID `JULIUs scHULTE, or LATROBE, rENNsYLvANIA.

srncrrrcnrron formingpart of' Letters Patent No. 549,159, atea November 5, 1895.

Applioatibn filed June 25,

Be it known that I, DAVID JULIUs SCHULTE, acitizzen ofthe United States, residing at Latrobe, in the county of Vestmorelad and State of Pennsylvania, have invented' anew and useful Car-Coupling, of which the follow-l ing is a specification.

The invention relates` to improvementsin car-couplings.

The object ofthe present invention 'is to.

improve the construction ofvear-couplings of the Janney type; to render the automatic operation of coupling positive, easy of action,l -so constructed as never to work hard, and to 1 5' prevent the knuckle' from being forced outwardor laterally o f the drawfh'ead when two 'cars' come together for coupling.

A further' object of the invention is to re" lieve the knuckle-pin of strain in backing, to prevent the knuckle-pin' from being broken,

,and to provide means for preventing two draw-heads from separating and one of themdropping to the track in ayer@ nfsuchdran head 'becomingdetached'from its car'.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fullydescibed, illustrated. in the acccompanying. drawings, and pointed v out in the claim hereto appended. I A ln the drawings, Figurel 1 is a perspective view of a car-coupling constructed in accordance with this invention', the knuckle being Fig. 2 is a longitudinal sectional View,-

' I the knuckle being closed. Fig. 3 is a horizontal sectional view. Fig.V 4 is a detail perspective view of the' knuckle. Fig. 5is areverse plan view of the 'car-coupling. Fig. 6

is a detail perspective view ofthe catch. Fig.4

7 is a similar view of the supporting-arm.

I -Like numerals of reference indicate corre- 'sponding parts in all the figures of'Y the draw.-

lngs. l

designates a drawfhead having the-gen# al; congnration o f the draw-headsl of the type, and' provided at one side with upp ,nd lower knucklepin-reeeiving eyes 2, `and .provided with a horizontal opening .3

to receive an arm 4 of a knuckle 5, which is pvotsd in the usual manner by a knucklepin.A 6, passing through the said. eyes and through aperforation of the knuckle.'

zvThe arm of the knuckle is adapted to be 1895. sesamo. 564,031. (No nada.)

engaged and locked by a substantially vertically-di`sposed catch 7, consisting of a bar arranged in openings '8 and 9 of the top and bottom of the draw-head and located 'in rear of the knuckle.

top of the recessll, adapted to be engaged beyond thev same. After the arm passes be the Lecess 11, the catch falls and llocks the knuckle in its closed position'. portion of the catch is inclined at 13, and the lower opening 9 of the draw-head is correinward, whereby when the catch is raised it moves vertically and rearwardly to release the arm 'of the knuckle to permit the latter to open. The lower end o f the, catch is provided with a perforation receiving a` key tolimit the upward movement of the catch, and any suitable means may be provided forenabling the catch to be lifted to effect the operation of nnc'ouplingfrom the topJ sides, 'or platform ofacar.

The knuckle is provided at its outer side with shoulders l14, formed by recessing the and to prevent the samey from being swu'ng outward when two draw-heads come together for coupling. 'lhe knuckle is providedat its inner side with shoulders 16,- arranged tobear draw-head to relieve the knuckle-pin of belo'w the arm.4, of the knuckle.

lnV order to prevent the draw-head from falling tothe track in event ofits being pulled out fromits'car, it is provided with a substanreadily attached to any ordinary draw-head `ofthe Janney type without altering the concomprises a downwardly-extending arm and by an inclined shoulder 12 of the knuckle' ,arm4 4,` whereby the knuckle in closing is. adapted to engagea-nd lift. the catchand pass,

struction of the carcoupling- The bracket` The bar is -provided with a recess,` and has' an inclined shoulder 10 at the v yond the inclinedA shoiflderldsatethe top of The lower spondingly inclined, extending upward'and eye of the knuckle,- and arranged to engage -v 'corresponding shoulders l5 at the side ofthe draw-head to limit the' opening of the knuckle against corresponding shoulders 17 of theI i strain when cars are .being backed, and the ,shouldersll' of the draw-head'. are` located in i rear of the knuckle-pin at points above and.

tially L-shaped bracket 18,- constructed of a' l e single piece of material and adapted to be l ICO 'a horizontally-disposed portion 'located .be-

its top with an enlargement, and it has a per- Y foration forthe reception of the lower end of a -knuckle-pin, whereby the device is adapted to be readily attached to-any ordinary drawhead of the Janney type, and is readily removable'therefrom when desired. It is retained on the lower end of the knuckle-pin by a key 19, and it is prevented from. rotating f and becoming displaced by a rearwardlyand upwardly extending arm 20, conforming to the configuration of the bottom of the draw'- Ahead and fitting in a recess or indenation of the bottomr'of the draw-head and locking the bracket rigidly in position.

It will be seen that the car-coupling is simple and inexpensive inl construction, that its' automatic operation is positive and reliable, and that the knuckle-pin is supported 'or relieved from strain in backing to prevent .the

same from being broken orfotherwiselinjured.

It will alsobe apparent that a simple and inexpensive device is providedfor preventing a draw-head from becoming.v uncoupled and dropping upon the track in event of its becoming detachedfrom its car, and that the device is readily applicable to draw-heads of the Jann ey type, and is rigidly held in proper position.

Changes in the form, proportiom-and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this in'- vention..

A supporting device for car couplings, designed to be arranged at the bottom thereof, and constructed of a single piece of material, and consisting of a substantially L-shaped bracket provided at its top 'with a knuckle in the presenceof two witnesses.
