METHOD OB PROCESS FOR FINISHING BEARING-ROLLERS.-

To all whom it may concern:

Be it known that 1, ROBERT SMITH, a citizen of :the United States, residing at Grand Rapids, Michigan,-have invented certain new and useful Improvements in Methods or Processes for Finishing Bearing- Rollers, of which the following is a specification. I v

This invention relates to improvements in methods-or processes for finishing bearing rollers.

The main object of this invention is to provide an improved method or process for finishing bearing rollers which enables the rapid and economical production of substantially perfect rollers.

Further objects relative to details will definitely appear from the detailed description to follow, in which the details of my improved method or process are set forth.

In carrying out my improved method or process I preferably employ the apparatus or machine illustrated in the accompanying drawing, in which:

Figure 1 is a plan view. Fig. 2 is a vertical section taken on a line corresponding to line 22 of Fig. 1. Fig. 3 is a detail of the member 12. Fig. 4 is a detail of the member 13. Fig. 5 is a sideelevation of one of the rollers which the structure illustrated is especially designed to finish.

In carrying out my improved process, the rollers are first formed by a screw machine or the like. They are then placed in a machine having coacting finishing members adapted to receive them along with master rollers of high-speed steel or the like, and brought to substantially uniform size. said finishing members is revoluble, or movable, so that the rollers are revolved under pressure, the feeding finishing memher being preferably adapted to remove surplus metal. The rollers are then taken from the machine, case hardened and replaced in the machine, a feeding member having a finishing surface being substituted for the cutting member. This removes any irregularity which may have been produced by the case hardening operation and reduces the rollers to a uniform sizeand shape and polishes the same.

Specification of Letters Patent.

At least one of I v Patented Dec. 29, 1914. Application filed January 25, 1910. Serial No. 540,049.

I will now describe the machine which I.

preferably use for this purpose, the same being made the subject matter of my application for Letters Patent, Serial No. 540,050, filed Jan. 25, 1910, which has matured into Patent No. 1,098,336, granted May 26, 1914-.

In the accompanying drawing, similar reference characters refer to similar parts throughout the several views; and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the support or base 1 is provided with projecting ears 2, adapted to receive the securing bolts 3 by means of.which the support is secured upon a table, or other suitable bed.

The-support lis provided with an annular seat 4. In this seat I arrange a finishing member 5, preferably a ring having an annular finishing surface 6 adapted to act on one end of the rollers to be finished, as at 8. These rollers illustrated are conical and of uniform taper from end to end, and

provided with conical small ends 8 and convex large ends 9, (see Fig. 5). On this member 5 I arrange the finishing member 10 which is preferably a ring having an inclined annular finishing surface 11 thereon, adapted to act on the sides of the rollers 7. I also provide finishing members12 and 13 for the large ends of the rollers. These finishing members are provided with annular finishing surfaces 14 and 15, respectively, the surface 14 of the member shown being toothed, while that of the member 13 is a smooth or polishing surface, as 15.

The finishing surfaces 14 and 15 of the members 12 and 13 illustrated are curved in cross section to form the convex ends of the rollers. The finishing surfaces 6 and 11 of the members 5 and 10 illustrated are smooth surfaces. These finishing members are formed of steel, preferably of tool steel.

A coacting rotatable finishing member 16 is provided, having a conical finishing surface 17, which acts on the sides of the rollers to be finished. A feed member 18 is provided for the finishing members 12 and 13, the

feed member being provided with a seat 19 adapted to receive either of the memberswith a lever 20 having a hole 21 therein adapted to be engaged over the pin 22' on the support 1.

The rotatable member 16 is provided with a driving shaft 23, the driving means not being here illustrated. The master rollers are shown at 24. These master rollers are of the size of the finished rollers or slightly smaller. These master rollers are preferably made of high speed steel. In carrying out my improved method, the rollers are just turned out with a screw machine or the like. They are then placed in the machine described, and the cutting member 12 inserted in the feed member 19. This is gradually fed down, and as the metal is forced up on the rollers by the finishing members acting on the sides thereof, it is cut or ground off by the member 12. The

finishing member 13 is then substituted for the cutting member and the rollers replaced in the machine along with the master rollers, and the machine operated to bring the rollers to uniform size. The rollers are then removed from the machine and case hardened. They are then replaced in the machine along with the master rollers, the polishing or finishing member 13' being used, the machine again operated until the rollers are brought to a nice polish or finish and any irregularityor roughness produced by the case hardening removed. By this process I am enabled to very rapidly and economically produce perfect rollers which have a very fine finish throughout.

. The machine illustrated is adapted for the finishing of tapered rollers having conical small ends and convex large ends, as shown in the drawing.

Having-thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The method of finishing conical bearing rollers, consisting of associating and arranging a plurality of such rough cut rollers in substantially their coacting relation with master rollers of correct dimensionsv interspersed therebetween, acting on the same by rotating finishing members conformed thereto in contact with the sides thereof and thereby revolving said rolls, applying a cutting tool to the ends of said rollers when thus revolving, thereafter applying a burnishing tool to the ends of said rolls with said master roller present, hardening said rolls by a suitable process, and again associating and arranging the said hardened rolls with master rolls and subjecting them to a burnishing contact withsuitable rotating finishing tools on their sides and to a. burbers conformed thereto in contact with the sides thereof and thereby revolving said rolls, applying a cutting tool to the ends of said rollers when thus revolving, thereafter applying a burnishing tool to the ends of said rolls with said master rollers present, hardening said rolls by a suitable process, and again associating and arranging the said hardened rolls with master rolls and subjecting them to a burnishing contact with suitable rotating finishing tools on their sides and to a burnishing tool on their ends, while revolving, to finish the same, as specified.
