PROCESS OF MANUFACTURING A DRAFT-YOKE FOR RAILWAY-CARS.
Specification of Letters Patent. I
' Patented Jan. 19, 1915.
Application filed September 30,1912, Serial No. 723,004. Renewed June 12, 1914. Serial No. 844,812.
To all whom it may concern:
Be it known that I, GEORGE A. JoHNsoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Processes of Manufacturing a Draft-Yoke for Railway-Cars, of which the following is a full, clear, concise, and exact description, reference being bad to the accompanying drawings, forming a part of this specification.
My invention relates to a process of manufacturing a draftyoke for railway cars.
The object of my invention is to provide a simple process of manufacturing a yoke for railway car draft rigging.
In the drawings Figures 1 and 2 show in plan and elevation respectively yoke stock formed to the shape of an ordinary wrought iron yoke. Figs. 3 and 4 show in plan and elevation respectively the yoke stock formed with two forwardly Y shaped members. Figs. 5 and 6 show in plan and elevation respectively the forwardly projecting Y-shaped members bent to meet at the longitudinal central line of the yoke. Figs. 7 and 8 show in plan and elevationrespectively the ends of the arms bent to over-lap in position for welding. Figs. 9 and 10 show in plan and elevation respectively the arms welded into two vertically and forwardly extended members or loops, and the yoke in its completed form.
My process consists in sawing or shearing a suitable distance rearwardly, as indiare horizontally parted along the saw or shear cut, and laterally bent to form two forwardly extending Y-shaped members, as illustrated in Figs. 3 and 4E. The opposite arms of the Y-shaped members are bent upwardly and downwardly respectively so as to meet at the longitudinal center of the yoke. The ends are staggered so as to facilitate their overlapping preparatory to Welding the same. These ends are overlapped, as illustrated in Figs. 7 and 8, and are then welded, forming the finished yoke as illustrated in Figs. 9 and 10.
I claim A process of making adraft yoke which consists in taking a U-shaped metal blank of suitable dimensions, said blank having its free ends separated into legs and said legs of each free end extending laterally, forming two Y-shaped members, brlnglng together the opposed ends of the legs so that they meet or overlap each other beyond the arms of the U-shaped blank, but in a line intermediate thereof, and then welding the opposed ends of the legs together.
