METHOD 01E FORE/ENG BRAKE-BEAM TRUNNIONS.
Application filed April 28,
To all whom it may concern Be it known that I, Learn L. Wnrrnnr, a citizen of the United States, residing; at Hammond, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Methods of Forming Brake-Beam Trunnions, of which the toll wing is a specification.
This invention relates to a method for forming brake beam ,trunnions.
An object 0'? this invention is to siinpli fy and improve the methods of forming brake beam trunnions, reducing the cost 01 menu- -i'acture and at the same time providing: a brake beam trunnion adapted. to meet the requirements for successful commercial use.
This and other objects are accomplished by means of the method disclosed on e accompanying sheet of drawings, in whi.h-
Figures 1 and 2 are end and top plan views, respectively, of a brake beam b t Figures 3 and 1 are end and top phn views or the same blank after being upset; Figures 5 and 6 are end and top plan views of the same blank after being further upset;
Figures 7 and 8 are end ano rep plan vlews of the blank after being; still further upset, the blank now being; shown as 3ovided with sufiicient built-up stock necesy for succeeding operations;
Figures 9 and 10 are end and'top pian views of the same blank after the end has been drawn out a Dredetermir er: 1
Figures 11 and 12 are end and top 3 views of the same blank atter being ups predetermined amount to approach the anal shape of the trunnion, there being a tin or flash left after this operation;
Figures 18 and. 14 are end and top plan views of the same blank after the fiash has been removed; and
Figures 1.5 and 16 are end and top plan views of the finished brake beam trunnion.
It will be noted from the figures of the drawing that only a portion 01'' the brake beam has been shown, it being understood that the opposite end or same will appear as the end shown.
The type of brake beam shown is of the plain I section. In forming the trunnion a commercial brake beam blank 10 of I section is provided, as shown in Figures 1 and 2. The end of the blank is then heated and at the proper points.
end of the blank 2. built-up portion 11 of stock, as shown in Figures 7 and 8, preparatory to the succeeding operations. It will be understood that during all of these upsetting actions the blank 10 is properly aripned bet-ween suitable dies to control the upsett ing The end of the beam is then drawn out between suitable dies on a steam hammer to the form shown in Figures 9 and 10, it being noted that the end 12 of the blank is rounded, which is the first rounding action given to the blank. The end of the blank is then upset a fourth time between suitable dies for shortening the trunnion portion 13 and forming a shoulder 14, it being noted that a fin or flash 15 is left around the trunnion which is caused by the junction of the dies, as shown in Figures 11 and 12. In the next operation the fin or flash 15 is removed, as shown in Figures 13 and 14, whereupon the blank is given its fifth upsetting action to give the trunnion 16 its final shape, as shown in Figures 15 and 16.
It is my intention to cover all modifications or the invention falling within the spirit and scope of the following claims.
I claim:
1. The method of forming a brake beam trunnion consisting in pro iding a blank, heating same,upsetting said blank to build up the stock for the trunnion, dr wing out said upset portion to approach the final trunnion shape, and then upsetting the drawn-out portion to give the trunnion its final shape. 1 r
2. The method of forming a brake beam trunnion consisting in providing a blank, heating same, upsetting said blank to build up the stock for the trunnion, drawing out said upset portion to approach the final trunnion shape, and then treating the drawn-out portion to give the trunnion its final shape.
Signed at Hammond, Ind, this 22 day of April, 1920,
I LOREN L. WHITNEY.
