pair of ends 6; and a both of substantially cylindrical form, one of them tapering at I (L2 to form an enlarged section near the center of the blank and having a circular disk shaped enlargement a at the large end of this tapering'portion. This is accomplished by placing the original blank in a-die 10 having a conformation like the blank shown in Fig. l and just described and bringing down on it a second'die of the same shape,
a plurality of times, preferably turning the second die 11 and. operated on by a similar vided with two cylindrical ends I) and I) made from the portions a and a. The die does not greatly alter these portions but it v somewhatgdraws them out so as to elongate them andsmooths them up. The por tion I)- has a tapering part b which terminates at a base b i-and then is drawn out smaller at b. The disk shaped part a is formed out at this stamping into two opposite. projections of? and I), both of cylindrical form, and in axial alinement. One is made longer than the other either in the dies is removed. It will be seen thereforethat these opposite projections are formed from a single integral piece of stock by drawing pressure, that each of theoperations so far described is performed in a single, pair-of --.or by cutting off their ends after the blank This disk shaped enlargement 'is v it is taken out of this die and placed in a die. These dies are formed to produce the blank-shown in Fig. 2. This blank :is prodies by repeated blows, and'that after one pair. ofdies has been used, and'the blank removed, the blankfneverhas to be-transferred back to it. These -projections 'constitute 'ax-t-ransversecylinder for the formation of. the bearing. -A small-projection Z2 also is formed to furnish some additional metal.
This blank having been formed, it is put intoone of the dies ordinarily employed for the blank which is usually manufactured by welding and formed up into the shape-- V shown in Figs. 3 and 4'. Inthis case a flat 1 9 them out transversely to the direction of I Figure 1 is. a plan of the blank after the tapering end a is provided and a cylindrical end on the other side having a flattened shank 0 The end 0 has wings a as usual, and the parts 6 and b are formed intosmaller and smoother cylindrical projections c and 0. This blank need not be described in detail as itis' well known in this art eX- cept that as heretofore made, the parts 0 and c are usually welded to the main body before it is shaped up into this form, whereas, according to this process they are integral with it thus eliminating ipractically all the waste due to imperfect welding. It will be understood, of course, that after this blank 0 is formedthe flier (Z'shownin Fig. 5 is formed up by the usual process, no
change being necessary in these operations;
it is handled is cut off to the proper length at a later stage in the process.
While I have illustrated and described a specific embodiment of the invention, Tam aware that many modifications can be made v therein without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited to all substantially the details of construction herein shown and 7 described, but
What I do claim is:'-
1. The method of forming'a flier, which consists in forming from 'ablank a long body provided with anj'integral substantially circular disk at a point near the .center thereof, then working said blank by drop forging to form a second shape having 'cy lindrical ends and an integral transverse forging this latter blank to reduce the thickness of one cylindrical .end and to form wings thereon, thus providing a substan-.
tially fiat member on: one end-and flattening the shank on the other end near the transverse member, and finally forging this blank and drawing it out to form the fiier.
2. The method of forming a flier which;
consists informing from a blank along cylindrical body,
cylindrical member near the center, drop forming thereon an integral transverse substantially cylindrical member near the center, drop forging this blank to reduce the thickness of one end of the long body to form opposite wings thereon to provide a substantially fiat member on one side of the transverse cylindrical member and flattening the shank of theother end near. the transverse member, and finally forging this blank and drawing out both ends to form the flier.
.In testimony whereof I have hereunto set niy hand, in the presence of two subscribing witnesses. p y
I CHARLES T. BURLIN.
