DRAFT AND BUFFING MECI-IANISM FOR RAILWAY-SARS. p e

Specification of Letters Patent.

Patented Mar. 13, 11917.

Appli-cationiled March 30, =1906. `Serial N0.f308,911.

i Lacanau, a citizen of the United States, re-

sidingat Collinwood, inthe county of Cuyahoga and State of Ghio, have invented certain new and useful Improvements in Draft and Bulfing Mechanism lfor Railway-Cars, of which the following is a. specification.

This invention relates to draft and buiing :mechanisms for Vrailway cars, and pertains 1more especially to Lthat class or type of such devices which require a comparatively wide range of lateral or angular movement of said parts on taccount of short and sharp` curves in the track. More specifically, the

invention belongs `to 'that class of devices in which `the bufling mechanism partakes 1 bodily `of the lateral movement of the drawbar, and lmaintainsa substantially7 constant relation tothe latter as :regards lateral or angular movement;

Among the leading objects of the inventionare to provide a mechanism capable of a wide rangefofangular movement, and in Vwhich 'the buffer plates of adjacent cars may maintain parallelism and `contact under all conditions; to dispense with the usual equalizer bar and one set of Iside stems; to provide improved means'of attaching the safety chains; to; provide an improved means of uniting the parts of a sec- :tional Vdraw-bar;` and, in generahto provide a reliable and efficient mechanism -of the character specified representing a relatively low cost of construction and maintenance.

To these ends the invention consists in the matters hereinafter described and more definitely pointed out in the claims.

My invention, in an approved mechanical form, is illustrated in the accompanying drawings, whereim- Y Figure l is a top plan view of the drawbar, draft-rigging, `and bufing mechanism, illustrating also a` means whereby the drawbar and draft-rigging may be laterally actuated from the truck;

, Fig. 2 is a longitudinal sectional View of the same; and

Fig. 3 is a cross-sectional view on the 0H- set line 3 3 of Fig. 1. Y

Referring to the drawings, 5 designates a longitudinal sill, and 6 an end sill of a car underframe, and 7 and 7a designate transverse I-beams forming hangers or carrier ends for the draw-bar and buing mech- .ings 8, front and j anism.- Somewhat inwardly ofthe forward `.end of the car-frame is located what I term the draft-rigging, the same comprising, in :the simple form shown, the usual stop castrear followers 9 `and 10, lresistance spring 11, and yoke 12, the forward end of which `latter' is pivotally `connected as by a pivot-bolt 13 to the vrear end of the draw-bar 14;, which latter is herein shown as of considerable length, and as consisting of forward and rear sections 14 and 114D connected end to end, as indicated at 14 -in Fig. 2, this being for convenience and economy in removing eithersection, especially the forward one, when necessary by reason of injury or wear, ywithout disturbing the other. r,I`he two .sections are unitedby upper and lower straps 15 and 16, respectively, which overlap both sections to a considerable extent, and are united thereto by through-bolts -17 and rivets 18.

Secured to Aand embracing the forward section `of the draw-bar, .slightly 'in rear of the coupler head 19 is what I `term ithe lbufl'er-.supporting frame; the same `consist- -strap 15 transversely thereof, land Aa generally U-.shaped casting 21 rigidly secured beneath `the same as I'by :bolts ,22 and ,embracing the draw-bar and straps, as clearly shown in Fig. 3. Atfthe ends ofthe casting 20 areformed pockets 23 to accommodate the buffer springs 24, said pockets being opened on their cute-11 sides to facilitate the lateral insertion of the springs. Disposed forwardly of the pockets 23 are guides 25 to accommodate the side stems 26 of the buiing mechanism, said stems at their rear portions being shouldered for engagement with followers 27 which in turn abut against the forward ends of the buliing springs, said stems having integral reduced portions or rods 26a extending axially through the springs and through the rear ends of the pockets, and retaining-nuts 28 and locknuts 29. The forward` ends ofthe stems 26 have lateral extensions'30 that are apertured, as shown atr31, for the connection thereto of the safety chains 32, and the forward ends of said stems, inwardly of the lateral extensions, are ypivotally connected by the usual buffer-plate 33.

The mechanism above described, when connected or coupled with the similar mechso j ' 1. In a draft and buffing mechanism, the vcombination with a draw-bar, of a buffer anism on an adjacent car, swingsfreely substantially into the Vline of draft between` the pivotal points lofthe respective drawbars, and, when disengaged, may be moved either manually, or by any suitable center-y ing or conti'olling device, such asthe truck@ actuated connection herein indicated as consisting Yof extensible connections Sil and 34 vbetween the draw-bar and the opposite sides of the truck, portions of the frame of the latter lbeing indicated at 85 and From the foregoing it willV be seen thatv Vforward section, to be removed and replaced when necessary without disturbing the rear Y section and the draft-rigging connected thereto. The lateral extensions of the side stems of the buffer mechanism form convenient points of attachment of the safety chains 32, and, in case the latter are called intoaction through injury or uncoupling of the coupler members, their pull is exerted throughV theV bilder-supporting frame, drawbar, and draft-rigging.

I claim:

casting overlying the same and secured (lopiesofV this patentmay be obtained for rlhe straps 15 and 16 Vform,

thereto, said casting having lateral pockets for the buffer springs, a depending casting secured to said overlying casting and em'- bracing the draw-bar, buffer springs in said pockets, side stems engaging said springs,

and a buffer-plate pivoted to the forward ends of said side stems, substantially as described.Y 2. n a buii'ng mechanism, the'rcombination of a buffer-supporting frame, of buer springs mounted. in either side thereof, side stems engaging said springs, a. buffer-plate connected tothe forward ends! of said side stems, and means for the attachment of safety chains to the VVforward ends of Vsaid side stems, substantially as described.

l 3.'In a bufngmechanism, the V,combination with a buffer-supporting frame, of buffer springs in eitherside thereof, side'stems engaging saidsprings and havingapertured Vlateral projections for thefconnectionof the .safety chains, and a Ybuffer-plate connected to and between the .Y forward ends V of'said side rstems, substantially as described.r ref. ln a buiiing mechanism for railway cars, the combination of a buffer-supporting frame, av buiiing cushion, a'bulfer-stem connection engagingthe same, and a safety chain co-acting. with said stem connection, substantially as described.V Y. 5.
