Original application filed April 18, 1914, Serial No. 832,995. Divided and this application filed September 26, 19142 Serial No. 863,745.
To all whom it may concern Be it known that I, EDWARD RAMSDEN, a
subject of the King of Great Britain, and a.
the plunger or pitman through resident of the town of Perth, in the county of Lanark, Province of Ontario, and 190mmion of Canada, have invented certain new and useful Improvements in the Method of Forging Steel Car-Wheels, of which the following is a specification.
My invention relates to improvements 1n the method of forging steel car wheels as described in the present specification and illustrated in the accompanying drawings that form part of the same.
My invention relates particularly to the process or method of forging. steel car wheels consisting in first shaping the bloom to present a tread part flaring from the flange and subsequently treating such bloom tocause contraction of the metal, whereby said flaring tread will become cylindrical.
As described in my application, Serial No. 832,995, filed April 18th, 1914, of which this is a. divisional application.
The objects of my invention are to provide a new, simple and inexpensive means for forming the flange and tread, whereby the necessity hitherto existing of machining is entirely eliminated, whereby the outside and best portion of the forging is retained, whereby the full allowance of three-inches for the tire is preserved, and whereby the cost of forging is considerably reduced.
IVith these and other objects hereinafter more fully explained, reference isnow had to the accompanying drawings in which the carrying out of the process or method is illustrated and in which like letters of ref figure, and in which,
Figure 1 is a side elevation with parts of the bloom broken away to show the operation of the tool. Fig. 2 is a front elevation of Fig. 1. Fig. 3 is a perspective view of my improved tool. .Fig. 4 is an under view of Fig. 3. Fig. 5 is a side elevation of a car erence indicate corresponding parts in each 1 wheel bloom.
Referring to the drawings, A represents which power is applied. B is the improved fianging tool formed with means 6 adapted to dove-tail into the said plunger. The tool B is provided with the flange pocket d, and formed with the slanting contacting face e,
flaring upward away from said pocket.
0 is the bloom having formed thereon the flange f and the flaring face-tread or tire portion 6, slanting upwardly from the flange f as formed by the upwardly slanting face of the tool B.
From the foregoing the operation as wellcontraction took place, the result being that the cylindrical formed tread was drawn inwardly. This, in the first place, to again make it cylindrical, and a standard tread necessitated a considerable amount of machining with consequent expenditure of time, to say nothing of the cutting away of the outside or best portion of the forging. In other words, the forging' flange was practically of no value, as it became necessary to machine the flange already forged in order to obtain a standard tread. In the second place, by reason of having to machine as above mentioned, the original allowance of three inches for the tread was reduced to two inches, thus destroying approximately fifty per cent of the mileage surface, and reducing accordingly the value and life of the wheel. Irregularities in other parts of the wheel beside the tread were also caused by such contraction of the metal, requiring further machining to fit it for use. Now with my invention this does not take place. The blank in the forging ,is formed with an outwardly sloping tread and subsequently on said blank being placed in the finishing dies the amount of drawing in oroontraction ther resulting acts on this outwardly sloping tread with the result that it becomes cylindrical, thereby forming without any machining or standard tread or tire portion of the wheel. My invention, therefore, saves the labor and time expended on machining the tread and other parts of the wheel to give it a standard form and'remove irregularities, and also saves the material of the wheel lost by such machining. The economic and vantages thus obtained will be not only apparent but enormous. 1
