DRAFT-PLATE FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Oct. 12, 1915.

Application filed September 23, 1914. Serial No. 863,111.

To all whom it may concern Be it known that 1', HENRY I. iVnmLnY, a citizen of the United States. and resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Draft-Plates for Railway-Cars, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to plates adapted to be attached to the sills of a railway car and to serve as means for transmitting thereto draft and bufiing stresses from the coupler.

More specifically it relates to plates of this character which constitute in themselves buffing blocks for receiving at their forward ends excessive buffing blows from the coupler horn, and which are also provided with draft shoulders or horns for engaging the inner face of the end sill of the car.

In draft plates of this type it is important that the forward end constituting the bufiing block should bear firmly against the outer face of the end sill and that the draft horn should bear firmly against the inner face of this sill. Car sills vary in size and are not fitted with exactness and it therefore frequently happens that the draft and buffing horns of the plate will not fit snugly against the timber. Looseness Offit may also be developed with service, partly due to the shrinkage of the material and partly due to its compression or abrasion.

The object of the present invention is to provide a wedging element fitting between the draft horn and end sill, and so constructed that it will automatically adjust itself and secure a tight fit. and will maintain such fit-automatically as it will advance to take up any looseness which may develop in the course of service.

An embodiment of the invention is hereinafter described, and is illustrated in the accompanying drawings, in which- -Figure 1 is a detail longitudinal section of a car showing the draft plate partly in elevation and partly in section; Fig. 2 is a detail plan section of the same; Fig. 3

is a detail section similar to Fig. 1, showing a slightly modified form of car construction; and Fig. 1 is a detail in perspective, and partly in section, of the draft plate.

The end sill of a car is represented at 10, and one of its center sills at 11. The draft plate, generally represented by the numeral 1:2, may be of any preferred form of construction as to the arrangement and location of its draft and buffing shoulders and as to the means for attaching it to the center sill of the car. It projects forwardly, as shown at 13, under and beyond the end sill 10, and is provided with an upstanding bufiing horn 14 for receiving on its forward face '15 the blows from the buffing horn 16 of the coupler 17, and for hearing with its inner face against the front face of the end sill.

Back of the end sill there is provided an upstanding horn, generally represented by the numeral 18, this horn being located adjacent the inner face of the center sill 11. The forward face of the h0rn 18 is inclined downwardly and forwardly, as shown at 19, and there is interposed between this face and the sill 10 a wedge-block 20, having a rearward inclined face conforming to the inclined face of the horn and a forward vertical face for engaging the sill, this forward face being preferably roughened for increasing its frictional engagement. The wedgeblock will automatically drop into place between the horn and sill, and will tend to work down under the influence of the vibration or weaving of the car frame and thus firmly clamp the sill between the two draft arm horns.

The important part of the invention consists in the means for connecting the wedgeblock with the draft horn. To this end the horn is provided with lateral flanges 21, 22, projecting in opposite directions from its web 23. The wedge-block 20 is provided with a pair of rearwardly extending lugs 24, 25, which embrace the front end of the horn, extending backwardly beyond its flanges 21, '22, and each being provided with an instanding boss 26 which hooks around or under the horn flange with which it cooperates. To facilitate assembling, oneof the flanges, as 21, is recessed at its rearward end, as shown at 27, to permit the boss 26 to enter, and the other flange, 22, recedes at its rearward end, as shown at 28, for the same purpose. The block 20 is first placed over the horn in the dotted lines position of Fig. 1, and then pushed forwardly and downwardly into place. By a blow of a hammer 7 upon the rearward end of the flange 22,

the point at which it angles inwardly, it is bent down, as indicated at 29. (Fig. 1),

thereby preventing accidental or intentional removal of the block.

' The bufling horn 1% extends laterally to the center line of draft, and is provided with an upstanding flange 30 adapted to bear against and be riveted to the corresponding flange of the companion arm, thereby providing greater rigidity of the bufiing element.

It is the practice with some car builders to extend the endsheathing 31 of the car downwardly over the front face of the end sill, as shown in Fig. 3. lVhen this construction is followed, the sheathing interposed between the bufling horn and the sill proper becomes in effect a part of the sill front face of the horn being inclined and provided with lateral flanges, a wedge-block applied, to such inclined face and having lugs hooking around the flanges.

2. A draft plate having a draft horn, the front face of which is inclined and provided with lateral flanges, a wedging block applied to such inclined face and having lugs hooking around the flanges, one of such flanges being recessed to permit the entrance of one of the lugs.

3. A draft plate having a draft horn the frontface of which is inclined and provided with lateral flanges, a wedging block applied to such inclined face and having lugs hooking around the flanges, one of such flanges having a shouldered end adapted to be bent down to prevent the disengagement of the lug.
