carrying out my invention I have designed a MAR'lIN F. CHRISTENSEN, or oLnvELA-Nnomd APPARATUS FOR PRODUCING inst-Attic SPHE-"RESU SPECIFICATION forming part of Letters Eatent No. 632,336,:1ated September 5, 1399; i
Application filed March 7. 1899.
To all whom it may concern.-
Be itknown -that I, Il/IARTIN F. CHRISTEN- SEN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Machines for and Methods of Forming Spherical Bodies; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon, which forms a part of this specification.
My invention relates to apparatus for producing metallic spheres, and the novel features of the invention will be fully described hereinafter and then defined in the appended claims. I
The accompanying drawing is' an elevation, partly in section, of the machine employed by me in producing metallic spheres or bodies.
In carrying out my invention I cut from a metallic rod of proper cross-section a blank of a length approximately equal-to its greatest diameter or cross-section. The blank may be slightly longer or shorter than the greatest diameter of the rod. The blank thus severed may be heated, if desired or found necessary; but in some cases the heating of the blank is unnecessary. The blank is now fed intoIa machine which will give to the blank a movement similar to a gyratory motion and will roll the blank about its axis in every direction, and thus knead the blank until the grain of the same in the finished ball has been contorted and the metal is in a sense homogeneous and has no special grain.
Spherical bodies formed in the manner above set forth are so rolled, kneaded, condensed, and compressed during their formation that the grain of the metal is contorted, and the product will not split, crack, or break, as do such bodies which are produced by drop-forging, turning, or by rolling the blank In machine which is especially adapted for the purpose. This machine is illustrated in the drawing and is preferably constructed substantially as follows:
A represen ts the base of my 1nachine,which is'preferably formed with an annular cham- Serial No- '7os,122. (No nae'iii- 1 her A, which serves as a receiver for the finished balls or spheres. The chamber A is v 5 5 provided with an outlet afor discharging the balls. Secured centrally lo the base andun-,
derneath the same is a hollow flanged boss 0,
which is screw-threaded internally, as at c, to receive the adjusting-screw C'.- The adjusting-screw 0' is provided with suitablemeans for operating or turning it,such as bars or handles (Rand also withapointer Cfflwhich cooperates with a micrometer-scale 0 thus forming a. micrometer adjusting device. A lock-nut G is provided for'locking the screw I C after it is'properlyadjusted. 1 l
D Drepresents hard metallicplates-which" l are so shaped that a ball-race for balls dis; formed between them. The-plates-D -D' are located above the screw -C'- and beneath, the vertical shaft E of the machine, thus forming. an antifriction step-bearing for the shaft E. F represents a vertical rotatable 'conicalroller which is mounted on and operated by shaft E. The operating-face of roller jF may be formed plain and smoother may berough; encd by fiuting or cross-tinting thereon in any suitable manner, either wholly or a part of its area. Shaft E extends vertically through the roller F and is supported at its upper porv tion in a suitablebearing E,aarranged in the upper end of a casing G, which-willbe-herein-y after described. CasingGsurrounds the conical roller F and is secured in anysuitable 85 manner to the base A, as by means of flanges g g and screw g and an annular mortise and tenon g, which forms a rigid conuectionzforl the parts. The inneror operative face of the casing G is provided with a spiral-groove G, which is preferably formed in the saidface, so as to be uniform both indepth and width and preferably of uniform pitch, Ialso pre- 7 fer to round the edges of the groove G, as; illustrated, which gives 10 theinner-face of the casing. l a'corrngated appearance. The object in rounding the edges ofthe groove G is to lessen the danger of cutting, abrading or shavingthe-blank duriugits manipulation in the machine, which might-result if the corners of the groove:G;-were left sharp.
The inner face of the casing G isiat an an-. gle. which is uniform throughout from its upper end to itsbase, and the angle'iscoincident with or the same as theangle' ofthe major portionof the roller I. ,In order to -or bite the blank, and thus more readily feed the blank to the machine.
As hereinbefore stated, the upper end of the casing G is provided with a bearing E for the purpose of supporting shaft E, and this hearing E is the main upper bearing for said 'shaft'and the roller F. Above'the hearing E, I provide a vertically-adjustable hearing E, which is located in and supported by a yoke G; The bearing E is provided with an external screw-thread which engages an internalthread formed in yoke G and it is adjusted by turning the bearing in the desired direction. A flange-head e, having notches e, is formed at the low-er end of the bearing E for the purpose of-adjusting'the bearing by means of a spanner-wrench. A
lock-nut I engages the screw-thread of the bearing E above the yoke (El and locks the bearingin its adjusted position. J represents a collar, which is adjustably secured to the shaftE beneath the bearing E by means of a screw j. The adjustable bearing E and collar J act as an auxiliary to the micrometer-adjustment beneath the step of the shaft E for the purpose of securingthe said shaft and its attached roller F from jumping or chattering. The upper end of the shaft'is provided with suitable devices for receiving motionsuch, for instance, as-a pulley K. In this connection a bearing L, properly sup ported, may be employed to steady the upper end of the shaft E.
