VVOLCOTT J. PARMELEE, OF \VILKES-BARRE, PENNSYLVANIA.
MACHINE FOR ROLLING AXLES.
SPECIFICATION forming part of Letters Patent No. 4A4,253, dated January 6, 1891. Application filed August 22, 1390. Serial No. 362 761. (N0 model.)
T0 at whom it may concern:
Beit known that I, WoLooTT J. PARMELEE, a citizen of the United States, residing at Wilkes-Barre, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Process of and Apparatus for Rolling Axles, of which the following is a specification.
This invention relates to the manufacture of vehicle-axles by rolling the spindles upon the same, instead of forging them under the hammer, as has been formerly done.
The invention consists in the improved process and apparatus which will be hereinafter fully described, and particularly pointed out in the claims.
In the drawings, Figure 1 is a side elevation of a set of rolls having dies to operate in accordance with my invention. Fig. 2 is a vertical sectional view of the same.
Like numerals of reference indicate like parts in all the figures.
The rolls, which are designated by l 1, are
suitably geared together and are provided 25- with longitudinal ribs 2, upon which the dies 3 and 4: are mounted. Said dies are provided in their faces, which are concentric to the axis of the rolls, with grooves 5 and 6. The grooves 5 in the dies 3 are semi-elliptical in contour, while the grooves 6 in the dies are semicircular. The dies 3 may be designated as the shaping-dies, while the dies 4 are the finishing-dies.
It is obvious that the grooves in both the shaping and the finishing dies are to be made tapering from end to end, so as to produce the requisite taper in the spindles which are to be formed therein.
In practice the blank, which is a bar of square iron of suitable dimensions, is heated to the requisite degree, and is then fed by the operator between the dies 3 of the rolls, which are caused to revolve by suitable motive power. end of the blank an elliptical and tapering shape. The dies, it will be observed, extend only part way around the circumference of the rolls. Hence the blank, after passing between and being operated upon by the faces of the dies, will be released by the latter,and may be readily withdrawn from the rolls without passing between the latter. The blank- The said dies 3 will impart to thebar is then, after being withdrawn from the rolls, reversed to the extent of one-quarter revolution and again fed between the dies 3. The efi'ect of this second manipulation will be that the spindle is upset and its elliptical shape changed to one which more nearly approximates the circular. Having undergone this second manipulation, the spindle end of the blank is passed between the finishing-dies 4, from which it receives the tapering and in cross-section the true circular shape. The blank is then ready for subsequent manipulat-ions to form the collar, after which it is trimmed in the usual manner by turning and otherwise.
By my invention a single set of rolls having suitably-constructed dies will besufticient to shape the spindle of the axle, which has heretofore been done exclusively by hammerforgingin a comparatively slow and expensive manner. I also desire to state that, while by the process of hammer-forging reheating of the axle is necessary to fit it for subsequent operations, my improved process of rolling the spindle is so rapidly performed as to render reheating unnecessary.
Having thus described myinvention, what I claim, and desire to secure by Letters Patent of the United States, is-
1. In the manufacture of vehicle-axles, the process of forming the spindle by rolling, which consists in first compressing the end of the axle-blank to a tapering shape elliptical in cross-section, nextupsetting the tapering elliptical portion by edgewise pressure to an approximate circular shape in cross-section, and finally finishing between tapering rollerdies circular in ci-osssection, substantially as set forth.
2. In the manufactureof vehicle-axles, the process of forming the tapering spindle by rolling, which consists in subjecting the blank to the action of revolving dies acting from the point in an inward direction, the blank being withdrawn from between the rolls after each operation of the dies, substantially as set forth.
3. In a machine for forming spindles upon axle-blanks, the combination, with the rolls, of the spindle-shaping dies mounted detachably upon the same, substantially as set forth.
4. The combination, with the rolls, of the spindle shaping (lies mounted (letachably In testimony that I claim the foregoing as IO upon and extending part way around said myown I have hereto aflixed my signature in rolls, substantially as set forth. presence of two witnesses.
