DRAFT-RIGGING FOR RAILWAY-CARS- Specification of Letters Patent.

Patented July 25, 1905.

T0 at whom, it may concern.-

Be it known that I, WILLIAM H. MINER, a citizen of the United States, residing in Ohicago, in the county of Cook and State of Illi 1101s, have invented anew and useful Improvement in Draft-Rigging for Railway-Cars, of which the following is a specification.

My invention relates to improvements in.

draft-rigging for railway-cars, and more par ticularly to tandem spring-draft rigging de *3 3 of Fig. 1.

In the drawings, A A represent the draftsills or portion of the carframe to which the draft-rigging is attached; A, the front sill; A a cross-sill; A the bufler-block; A, the movable buffer-plate; A the buffer-stem; A, the buffer-spring, and A the buffer crossbar. All these parts are of any suitable or ordinary construction.

B is the coupler, B the draw-bar, and B the draw-bar strap or yoke secured to the rear end of the draw-bar by a pivot b.

O C are tandem-arranged springs, D D D D the followers, and F F are the side plates or stop-castings. Each of the side plates or stop-castings F is provided with outwardly and upwardly extending brackets or armsfto fit against the vertical webs a of the draft-sills A, to which said brackets are secured by bolts or rivets f. Each of the side plates or stop-castings F is further provided with an outwardly-projecting horizontal flange f fitting against and beneath the lower flange a of the draft-sill A, and also with an upwardly-projecting shoulder or flange f, fitting against the outer edge of said flange a of. the sill A. Bolts or rivets f 3 secure said outwardly-projecting flange to the draft-sill A. Each of the side plates or stop-castings F is provided with an integral upper guide f 4 for the followers, said integral guide f consisting of an inwardly-proj ecting flange on the side plate F. The side plates or stop-castings F are furnished each with removable guide-plates G at their lower edges, secured thereto by short or stub bolts g, eX- tending through feet or projections f 5 at the loweredges of the sideplates or stop-castings. Each of theside plates or stop-castings F is further provided with downwardly-projecting. intergal brace-arms F F to enable the two side plates or stop-castings to be rigidly braced apart and rigidly connected together by transverselyextending bracethimbles K and connecting-bolts K, extending between said brace-arms below the drawbar strap or yoke B and followers. Each of the connecting-bolts K is furnished with a head 7: and with a threaded nut 7c and lockkey k By this means or construction the draftrigging may be made very strong, durable, safe, and reliable and at the same time be mounted entirely below the draft-sills, as illustrated in the drawings and as is frequently required in practice to accommodate or adapt the draft-rigging to particular car constructions.

I claim In a draft-rigging, the combination with the draft-sills, draw-bar, draw-bar extension, springs and followers, of a pair of side plates or stop-castings having outwardly and upwardly projecting brackets fitting againstthe vertical webs of the draft-sills and outwardlyprojecting flanges fitting beneath and secured to the draft -sills, and provided with integral downwardly-projecting brace-arms and brace-thimbles and connecting-bolts extending between said downwardly-projecting brace-arms of the side plates or stop-castings, substantially as specified WILLIAM H. MINER.
