FRlCTlON DRAFT-*RIGGING FOR RAILROAD-CARS.
SPECIFICATION forming part of Letters Patent No. 717,677, dated January 6, 1903. Application filed November 5, 1902. Serial No. 130,136. (No model.)
To all whom it may concern:
Be it known that 1, JOHN J. HENNESSEY, a citizen of the United States, residing in Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Friction Draft-Rigging for Railway-Cars, of which the following is-a specification.
My invention relates to friction draft-rigging for railway-cars, and more particularly to the construction of the side plates or stopcastings employed therein. 7 V
The object of my invention is to provide a friction draft-rigging of a simple, strong, and durable construction, in which the opposing or engagingsurfaces between the transversely or vertically movable frietion-blockand the side plates or stop-castings shall be composed of suitable metals of different kinds or characters to secure proper wearing and friction surfaces and increase the durability of the draft-rigging as a whole.
My invention consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described and by which this object or result is accomplished.
In the accompanying drawings, forming a part of this specification, and in which simi- 'lar letters of reference indicate like parts throughout the several figures, Figure 1 is a vertical section of a friction draft-rigging embodying my invention, taken on line 1 1 of Fig. 2. Fig. 2 is a plan view, partly in horizontal section, the sectional part being on line 2 2 of Fig. 1. Fig. 3 is an enlarged detail horizontal section of one of the side plates or stop-castings. the same. Fig. 5 illustrates a modification, and Fig. 6 illustrates my invention as applied to a side plate or stop-casting for use in a friction draft-rigging having two transverselyarranged springs and friction-blocks arranged tandem.
In the drawings, A represents the drafttimbers, A thecenter sills, A the cross-sill, A the bufier-block, A the bufier-plate, A the carry-iron, B the draw-bar, and B the coupler, these parts being all of any suitable construction.
D is the sliding friction-draw-bar extension or sto p-castings Fig. dis a side elevation of or draft-iron, the same being directly in line with the draw-bar and connected thereto by d of the draft-iron is in sliding frictional engagement with the stationary friction face or plate G on the stop-castings F,'. the same being preferably formed in a separate piece therefrom, butsecurely anchored thereto.
H is the transverselymovable frictionblock, the same having double-incline friction-faces h h, engaging corresponding friction-faces d d on the draftsiron. The friction-block H is also provided with an integral downwardly-projecting flange or cup h to receive and guide the springK, which acts against the block H and is supported in a removable spring seat or cup K, secured to the stop-castings F-by cotter-bolts K The ver tically or transversely movable friction-block H is guided in its transverse or vertical movement and held from longitudinal movement by vertical guides or shoulders f on the side plates or stop-castings F, which are also provided with inserted wearing pieces or blocks of different material from theside plates and from the transverselymovable block to increase the wearing qualities and durability of the parts. The inserted pieces or blocks f are secured in place by rivets f and are preferably of the form illustrated in Figs. 8 and 4 for a single-spring draft-rigging or in Fig. 6 for a double-spring draft-rigging, so as to give a wearing-face of different material for both corner-faces of the block H and also a Wearing-face f for the vertical face of the draftiron. If desired, however, the inserted wearing pieces or blocks f may be of simple angle form, (illustrated in Fig. 5,)in which case the side plate F is provided with a shoulder or rib f to form a recess or socket to receive the inserted piece f As illustrated in Figs. 3, 4, and 6, the inserted piecesf have a flange or shoulder f to embrace the upright guide f of the side plate or stop-casting.
The draft-iron D is provided with shoulders or stops d which engage corresponding shoulders or stopsj" on the side plates or stopcastings to limit the longitudinal movement of the draft-iron and draw-bar connected thereto.
I claim 1. In a friction draft-rigging, the combination With a draw-bar, of a draft-iron in line therewith, having a straight friction-face on one side and double-incline friction-faces on the opposite side, a transversely movable friction-block having double-incline frictionfaces engaging the double-incline frictionfaces on the draft-iron, a transversely-arranged spring acting against said frictionblock, and side plates orstop-castings having a straight friction face or plate with which the straight friction-face on the draft-iron is in sliding frictional engagement, and provided with upright or transverse guide-surfaces for said transversely-movable frictionblock of different material from the side plates or stop-castin gs, substantially as specified.
2. In a friction draft-rigging, the combination with a draw-bar, a draft-iron in line therewith having a straight friction-face on one side and double-incline friction-faces on the opposite side, and a transversely-movable friction-block, of side plates or stop-castings secured to the draft timbers and having guides extending transversely to the draftiron for said friction-block provided with inserted Wearing pieces or blocks of different material, substantially as specified.
3. In a friction draft-rigging, the combination-with a draft-iron having a straight friction-face on one side and double-incline friction-faces on the opposite side, of side plates or stop-castings secured to the draft-timbers and provided with guides extending trans- Versely to the draft-iron having inserted Wearing faces or blocks of different material, substantially as specified.
4. In a friction draft-rigging, the combination with a draft-iron having astraight friction-face on one side and double-incline friction-faces on the opposite side, of a transversely-movable friction-block having doubleincline friction-faces, a transversely-arranged spring acting against said block, side plates or stop-castings, a stationary friction face or plate thereon engaging the straight frictionface of the draft-iron, and provided with upright guides for said transversely-movable friction-block, said guides having inserted Wearing pieces or blocks of different material, furnished with a face engaging the vertical side of the draft-iron, substantially as specified.
