DRAFT-HIGGING FOR RAILWAY-CARS.

' State of New York, have invented certain new and useful yImprovements in Draft,

Rigging for Railway-Cars; and I do hereby declare the following to be a full, clear, and. exact description of thesalne, reference be ing had to the accompanying I drawings, forming part of this specification.

This invention relates to draft rigging for railway cars, the objects of the invention being to make a structure of maximum etliciency which will occupy a very limited space and which, at the same time, may be assembled on a car at a minimum expense.

Theximproved rigging of the present invention 'provides for the proper {ieXibilit-y of mov-ement of the cars with relationto each otherin a very compact space without seriously "cramping or distorting any ofthe parts of the rigging, and, by reason of its compact-ness, the Vdevice is particularly adapted for use in cars having no platforms and with little overhang beyond the bolsters, It will be understood, however, that the features ofthe invention may be embodied in draft rigsuch as ore cars and the like.

ging for any type ofy car, wherein it is desired that a compact rigging of maximum efficiency be employed.

The invention consists in certain, novel. details of construction and combinations and arrangements of parts as will. be .herein after described and pointed out particularly in the-appended claims.

In the accompanying drawingsfe Figure -1 is a rigging 'constructed in accordance with the present improvements. f Fig. 2 is a longitudinal section of the Fig. 3 4is a front elevation of the rigging. Fig., a isa `section on the line 4.-4 of Fig. 1.

this member is` located behind the follower plate F which occupies a position to the rear of the vertically lalined inner 4flanges bs of the castings B, B and bridges the cou ler shank opening in the front castings ig. 2). Connected with the pin E are the side members g of a draft yoke G. Said draft yoke is preferably composed of a single bar or member, substantiallyU-shaped and with its 'forward open end receiving the shank C", and its rear closed end g passing around the bottom of the pressure resisting member. -The forward ends of the side members g of the yoke are provided with elongated slots g to receive the pin E, and to permit the rearward movement of the pin E 1n unison with the coupler shank, it being under-` i with a washer and Cotter pin e', although this rearward movement stood that durin remains stationary. Un-

the draft yoke der draft stress the yoke is carried forward b'y the pin E. The pin E may besecured to -its connected parts by providing it with a head e at one end and at the opposite end `any. other method of preventing slipping of the pin will besuicientfor'the purposes of ...thepresent invention. Between the follower plate F and the rear 4endg of the draft yoke is the yielding pressure resisting', memberwhch, in the present embodiment is of the type in my co4 by tapering vertical websmz. vertical web ms extends from the rear of the Y into engagement with the wedge blog ks and also intoengagement with a tongue f on the followery plate F. ASaid wedge blocks are sultably recessed or slotted for the `reception of the tongue f of the follower plate, aslmore fully set forth in my said co-pending application. The wedge blocks H and the center wedge K augment the springl resistance'by frictional resistance, a feature'common to many patents heretofore granted this applicant. It will be understood that the pressure resisting member operates both under draft and buiiing stress, to absorb the strain in a manner'well known in the art. Under buliing stress, the' st-rain is transmitted to the friction blocks by the follower plate F, the barrel L remaining stationary and the movement of the blocks is against the ielding resistance ofthe springs within t e barrel. Under draft'stress, the Afollower -plate F remains stationary abutting against the vertically alined inner llanges b of the frontstop castings, whereas, the barrel moves, the strain being. .taken up by' the friction blocks and the springs within the barrel.

Fixed between the 'sills A and positioned to the rear of the barrel L and-the rear end of the draft yoke G is the rear stop casting M. According to the present invention, this stop casting .is constructed of such cross section as to impart maximum strain resisting properties to the casting. The casting, which isv fram-ed' in between the .sills A, 1s provided'with 'a front bumpingface m, of

somewhat less transverse dimension than the main rear' portion ofthe casting and connected with th'e rear side vertical webs m The central i bumping face m and is reinforced by transverse Webs m* which connect the opposite .sides of the central vertical web with the side webs m. The central vertical web 'm3 is further reinforced by horizontal flanges m5 extendingv alongfeach side of the web Yand l'preferably tapering from the rear of' the bumping face', into the op osite sides of the web, as shown in Fig.'1. he tapering Vertical webs m2 are respectively reinforced by inner horizontalilanges m5.

The :bottom of the spring barrel L is provided vwith a reinforcing member N, this vbeing acasting or other suitable means for thickenn up the bottom of thetbarrel. To avoid' ma 'ng a heavy section of metal the .reinforcing memberis provided with open- -l, as shown'fin Eig'.;2.
