Specification of Letters Patent.
Patented Dec. 2'7, 1921.
Application filed February 25, 1920. Serial No. 361,078.
ingris a full, clear, and exact description.
he invention relates to the manufacture of drawbar yokes and its object is to provide an improved method of forging one-piece yokes.
The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.
In the drawings: Figure 1 is an elevation and Fig. 2 is a plan of a channeled blank from which the yoke is forged. Fig. 3 is an elevation and Fig. 4 is a section showing the blank after it has been cut to form draft-gear openings and key-slots and after its ends have been trimmed. Fig. 5 is an elevation and Fig. 6 is a section of the blank after the endportions have been bulgedoutwardly and shaped and the flanges have been notched. Fig. 7 is an elevation of the blank after its flanges have been shaped for overlapping. Fig. 8 is a plan and Fig. 9 is a horizontal section of the finished yoke. Fig. 10 is a section on line 10-10 of Fig. 9.
The yoke is forged from a longitudinal bar 10, preferably of rolled or wrought steel. Said bar has top and bottom flanges 11 and 12 and a connecting web 13. This bar is ofsufiicient length to form both sides of a yoke and may, if desired, be cut from long stock. Four openings 16 are cut throughthe web 13, as shown in Fig. 3. These openings are spaced apart to leave a vertical columnar portion 17 medially of the blank, between the flanges. area to receive one side of a draft-gear. The portion 17 is adapted to be formed into the back of a yoke, integral with the sides. A key-slot is cut through the web adjacent each end of the blank. The end-portions of the flanges are out ofl and the web is trimmed on convergent lines, as at 18, to form rounded narrowed ends. The metal adjacent the These openings are of sufficient- "ofa outer ends of each key-slot 19 is swaged or upset, as shown at 20, to form an enlarged or reinforced bearing for a key in the slot. Next, the web portions 26,, which are outwardly of the draft-gear openings 16, are bulged outwardly and, inclined away from the plane face of the blank. Medially, the flanges are notched or cut away, as at 28.
Next, one portion 11 of flange 11 and a portion 12 of the flange 12 will be forged into offset relation with respect to remaining 7 portions 11 and 12 Fig. 7 Next, the blank will be bent and doubled transversely on a medial line to form sides in juxtaposition and with the key-slots and draft gear openings transversely alined. This bending operation will bring the flangeportion 11 and 11 in lapped relation andthe lower flange- portions 12 and 12 will be similarly lapped. The front portions of the lapped flanges are then secured together by rivets 30, and then the yoke will be finished.
The bulged web-portions 26 and adjacent lapped flange-portions form a coupler-shank pocket. Openings 16 are adapted for the lateral insertion of members of tandem draftgear, as well understood in the .art. The edges of these openings form abutments for the draft-gear members.
The invention is not to be understood as re stricted to the details set forth, since these may be modified within the scope of the ap pended claims, without departing from the spirit and scope of the invention.
Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is:
1. That improvement in making railway draft-gear yokes which consists incutting a plurality of draft-gear openings in a bar of metal, forming the ends of the blank for keying to a coupler shank, forging oflset marginal flanges on the doubling the blank tobring the draft gear openings into transverse alinement.
2. That improvement in making railway draft gear yokes which'consistsin cutting a plurality of draft-gear openings in the web marginally flanged bar of metal,"forming the ends of the blank for keying to couresp'ectively, as shown in blank, and bending and metal forming the ends of the blank for keyingto a coupler shank, forging the offset marginal flanges on the blank, bending and doubling the blank to bring the draft gear openings into transverse alinement and securing the lapped flanges together.
