DRAFT-RIGGING.
SPECIFICATION forming part of Letters Patent No. 711,822, dated October 21, 1902.
Application led August 5,1902.
To all whom it may concern:
Be it known that I, PATRICK M. CANTY, a citizen of the United States, and a resident of Altoona, in the county of Blair, in the State of Pennsylvania, have invented certain new and useful Improvements in Draft-Rigging, of which the following is a specification.
My invention is an improvement in draftrigging for railway-cars, and particularly in the means whereby the draw-bar is yieldingly connected with the car so it can yield longitudinally to a limited extent in both directions, and thus cushion the longitudinal strains on the said bar; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed. I
In the drawings, Figure l is a perspective view of my improvement in connection with the longitudinal angle steel stringers of a carframe. Fig. 2 isa top plan View ofthe box-v ing and the parts therein, the lid being omitted. Fig. 3 is a cross-sectional view on about line 3 3 of Fig. l. Fig. 4. is a detail perspective view of the rear end of the draw-bar. Fig. 5 is a detail perspective view of one of the wedge-blocks.
In carrying out my invention I provide a boxing` A, whose interior A is adapted to receive the double frusto-conical end B', the wedge-blocks C, and the springs D, the interior or recess A' of the boxing A being open at the top and closed in practice by the plate E, as shown in Figs. 1 and 3. The boxingA is provided in its front plate A2 with an opening A3, in which operates the draw-bar B, as will be understood from Figs. l and 2, the said draw-bar being in practice provided with any suitable form of coupling device. At its upper end the boxing A is provided with lateral flanges A4, which rest upon the horizontal wings F of the stringers F, the body of the boxing fitting between the upright wings Fa of said stringers and being secured rigidly thereto by means `of the rivets G, as will be understood from Figs. l and 3. The top plate F. is secured by rivets H to the lateral fianges A4 of the boxing. By this means the vboxing is firmly secured to lthe framing of the car and the top plate is secured in place over the recess or interior of lthe boxing, wherein serial No. 118,459. (No modem' and the rear end will taper inwardly Itoward the rear.
The end B of the draw-bar operates between the front-and rear wedge-blocks, of which I iemploy four, as shown in Fig. 2.
The wedgeblocks are alike in construction, so that the illustration and description of one will answer for all. In Fig. 5 I show the block I as provided with the body portion I', sloped on its inner face I2, and the shank I3 at one end of said body portion, the outer side of the wedge at I4 being straight from the outer extremity of the shank I3 to the point of the wedge, as will be understood from Figs. 2 and 5. The spring D bears between the outer straight sides of the wedges I and the walls of the chamber A of the boxing and is preferably in the form of a plate .bent at its middle at D and between said middle and its ends to produce the bows D2, which operate upon their -respective wedge-blocks, as shown in Fig. 2. By the described construction the draw-bar may be moved in either direction to such extent as to iatten the springs D against the side walls of the chamber A without in any way injuring any of the parts and will when so adjusted have a solid surface to prevent it from further movement in such direction. The shanks Irol operate to properly space the body portions of the wedge-blocks away from the ends of the chamber A and preserve said blocks in position to properly operate in connection with the double :frusto-conical head of the draw-bar, as will be understood from Fig. 2 of the drawings.
By my invention I provide a construction which is simple, can be readily applied to the framing of the car, will yield properly in both directions, will afford an unyielding bearing for the drawbar at the end of its ICO movements in both directions, and which cannot be pulled out of the car in the use of the latter. I am also by the described construction able to employ solid wedge-blocks and to arrange the springs to bear between the outer sides of such solid wedge-blocks and the walls of the chamber in which they operate.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
l. The improvement in draft-rigging herein described comprising the boxing having a chamber for the wedge-blocks and rear end of the draw-bar and having in its front end an opening for the draw-bar and at its upper side the lateral flanges for connection with the stringers of the car-frame, the draw-bar operating in the front opening of the boxing and having a double frusto-conical end operatin gin the chamber of the boxing, the wedgeblocks having the body portions sloped to coincide with the double frusto-conical end of the draw-bar, and the shanks by which said body portions are spaced away from the ends of the boxing, the plate-springs bent to form the bows operating between the wedge-blocks and the adjacent sides of the boxing, and the top plate secured over the chamber of the boxing, substantially as set forth.
2. The combination with the boxing and the draw-bar having a double frnsto-conical end operating in the boxing, of wedges having body portions sloped to coincide with the frusto-conical end ofthe draw-bai-,and Shanks by which the body portions are spaced away from the ends of the boxing, and springs oper- -ating upon the wedge-blocks, substantially tongues for spacing them away from the ends' of the boxing, of the boxing in which said devices operate,said boxing being provided with lateral anges whereby it may be secured to the car-frame, substantially as set forth.
5. The combination with the boxing, of the draw-bar having a double frusto-conical end portion operating within the boxing, of the wedge-blocks sloped on their inner faces to bear against the corresponding faces of the frusto-conical end of the draw-bar and bearing attheir outer ends against the ends of the boxing, and springs operating between the outer sides of the wedge-blocks and the boxing, substantially as set forth.
