SPECIFICATION forming part of Letters Patent No. 268,553, dated December 5, 1882.

' Application filed July 22,1882. N0 model.)

.To all whom it may concern:

Be itknown that I, MOSES SEWAR-D, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Dies for Forging Carriage Fifth- WVheels; and 1 do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference .marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1,a face View of one part of the fifth wheel to be produced; Fig. 2, a longitudinal section of the two parts of the die; Fig. 3, a face view of the lower part; Fig. 4,a longitudinal central section of the plate.

This invention relates to the construction of dies for the manufacture of that part'of carriage-iron work commonly called turn-plate or fifth-wheel, the object being to construct illQhOIiZOIltfil bar with a segment at each end of sufficient length to take the turning bearing, and with the center forged complete and ready for market as an article of manufacture; andthe invention consists in the dies, as hereinafter more particularly described.

A represents the lower part of the die, and B the upper part. In the lower part a longi tudinal cavity, 0, is made corresponding to a horizontal bar, D, of the plate or wheel. At

each end is a segment-shaped cavity, E, corresponding to the segment-shaped bearings F on the bar, and at the center is a cavity G, correspondingto a central stud, H, on the bar, and near the segment at each end is a transverse cavity, a, correspondingto a transverse rib, b, on the plate. The space between the ribs 1) and their respective segments is for the location of theclip, the ribs preventing the clip from. slipping in one direction and the 1 segments in the opposite direction.

I The upper part, B, is constructed with aflat face, the reverse side of the plate being flat. The blanks from which the parts of the plate are to be forged are made from a straight bar of the proper size, upset to present a sufficient amount of metal at each end to form the segment at the respective end. The dies are arranged in a drop in the usual manner, the blanks placed over the cavities, in the lower die, then the upper part of the die struck thereon to force the metal into theoavities in the lowerpart of the die A. Then the plate is trimmed by dies corresponding in shape to the outline of the plate. The two parts are forged alike, leaving a stud, H, at the center produced by the central cavity, G, and these studs are turned or fitted so as to form a projection in one to extend into a cavity in the other, as seen in Fig. 4 but in forging both parts are made alike, the subsequent work being the work of the machinist or smith upon the article. By the employment of these dies I am enabled to produce these plates and furnish them to the trade as an article of manufacture.

While Ihave described the dies as working the flat part up and the recessed part below, it will be understood that this order may be reversed.

What I claim is- The herein-described dies for forging carriage fifthwheels,

consisting of one part, A,

having the longitudinal cavity 0 terminatingin the segment-shaped cavity E at'each end, and with the central cavity G, substantially as described.
