Application filed January 8, 1925. Serial No. 1,286.

My invention relates to filler blocks or plates for use in connection with draw bar yokes of railway cars and the like, and to a method of making the same.

One object of my invention is to provide an improved manner of forming filler plates of the desired contour; another object of my invention is to provide a filler plate of improved form; still another object of my invention is to simplify and improve generally the structure and shape of filler plates and the like.

One form which my invention may take is shown in the accompanying drawing wherein Fig. 1 isa sectional view showing a filler plate being formed between two dies, in accordance with my invention; Fig. 2 is a plan view showing the appearance of the forged article upon removal of the dies; Fig. 3 is a similar View showing the article completed; Figs. 4 and 5 are sectional views 16 intermediate its edges, to form seating on the lines 4l4; and 5-5, respectively, of

Fi 3 and Fi 6 is a View aartiallv in D J b .1

bottom plan and partially in section, showing the manner of application of the com pleted article to a draw bar yoke. The blank from wliichthe filler plate to be formed is preferably of substantially the same thickness as that desired forthe completed article, and has a rectangular area substantially equal to the largest rectangular area of the finished article. The blank may also be of uniform thickness throughout, and is placed between dies 8'and 9 preliminary to the forging operation. Thedie 9 is provided with projections 10. and 11 by means of which pockets 12 are formed in the plate 7 and with elongated projections by means of which the pockets'13 are formed.

The dies are provided with recesseslt into which metal may flow when they are brought together, to form shoulders 15. ,The upper die is also provided with rounded surfaces surfaces 17. The metal displaced by the projections 10 and 11 and the curved surfaces 16 is caused to flow into the recesses wherein the projections 15 are formed. In order to insure that all corners of the dies dies.

shall be properly filled with metal, more metal is usually provided in the blank than just suflicient to fill the spaces between the This surplus metal forms afin or what is known as. flash between the dies, as indicated at 19. When the dies are removed, leaving the completed article as shown in Fig. 2, the flash 19 is trimmed away. In-

the for in oneration draft is "iven to the o :3 l L1 article as indicated at 20 and clearance thereby provided between the forward corners of the plate and the legs of the draw bar yoke 21.

The projections-15 upon the upper edge of the plate serve to support it upon the yoke 21, as shown in Fig. 6. 1 Shoulders 22 are formed on the lower edge of the plate by reason ofthe depression made in the,

blank to form the curved bearing surfaces 17. hen the plate has been inserted in the yoke and slid backwardly to its seat, as shown in Fig. 6, the projections 22 will extend beneath the lower edge of the yoke 21, thus tending to prevent the plate from beingforced upwardly out of the yoke. Q

The pockets not only reduce the weight of the filler. plate, but the metal formerly contained therein is largely utilized to form the lugs 15. Furthermore the presence of the pockets results in spaced seating surfaces on the rear side of the plate so that it will not be so. likely to tilt or rock upon the end wall of the yoke. The curved surfaces 17 fit the yoke more closely at the bends thereof, thus avoiding damage to the yoke,

such as would occur if thecorners of the plate were not rounded. The clearance provided at 20 avoids the necessity of grinding the forward corners of the plate and enables it to be more. readily placed in the yoke and to properly sea-t within the same, notwith r standing the presence of slight irregularities therein.

I claim as my invention:

A filler plate for draw bar yokes which are curved at their closed ends, comprising a drop forging having vertical corner portions depressed to form rounded seating surfaces corresponding in dimensions and complementary in shape to the inner end face ot' of the body portion of the plate, and the a yoke, and having-undepressed shoulderlower shoulder portions lying within the like portions at the upper and lower ends boundaries of the vertical edges of the 10 of said depressed portions, for engaging the body portion of the plate.

5 upper and lower edges of the yoke when in In testimony whereof I, the said HARRY assembled position, the upper shoulder por- T. ANDERSON, have hereunto set my hand. tions projecting beyond the vertical edges HARRY T. ANDERSON.
