ROD-POLISHING ACCESSORY.

SPECIFICATION forming part of Letters Patent No. 587,973, dated August 10, 1897. Application filed October 28, 1896. Serial No. 610,263. (No model.)

To [LZZ Ll/7min it may concern/.- 7

Be it known that we, LAZARD KAHN and MARTIN LoNeEELLoW, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Rod-Polishing Accessories,of which the following is a specification.

Our invention relates to a device accessory to polishing wheels or belts for use in polishing rods, the accessory being a device to aid the workman in supporting the rod and presenting it to the wheel or belt.

The invention will be readily understood from the following description, taken in connection with the accompanying drawing, which is a perspective view of a device eX- emplifying our invention.

In the drawing, 1 indicates a portable standard with its lower end adapted to rest upon the floor and preferably somewhat sharpen ed to permit it to take a good grip on the floor; 2, a handle on the upper portion of the standard 3, a pair of bearing-wings carried by the standard at a height from the floor corresponding with the height at which the rod is to be presented to the polishing wheel or belt, these wings being disposed side by side and a few inches apart; 4-, perforations in these wings adapted to loosely receive the rod to be polished and support the rod in a substantially horizontal plane, our preference being that each of the wings should contain several perforations of varying sizes, so as to be suited to various sizes of rods; 5, the rod to be polished, the same being passed through and carried by the proper-sized perforations in the two wings, and 6 a polishing-wheel.

' In using the device the workman places the rod in the proper perforations in the wings and places the standard in such position as to present the rod across the face of the polishing-wheel. By means of the handle, which is held by one hand, he supports the standard and presses the rod against the wheel with a proper degree of force. The contact of the wheel with the rod rotates the rod and results in the polishing of its circumference at the lengthwise portion presented to the wheel. While the rod is thus rotating, the workman, grasping the rod Where it extends to one side of the standard, feeds the rod endwise, the feeding motion taking place with a screw-like action due to the rotation of the rod and its oblique presentation to the wheel, the obliquity of presentation being secured by having the aperture in one wing a trifle higher than the corresponding aperture in the opposite wing or by leaning the standard a trifle sidewise. In practice it will be found almost impossible to secure anything but an oblique presentation of the rod to the wheel, and consequently the endwise feeding of the rod will be automatic, and the action of the workmans hand as he grasps the rod is more a matter of regulation of feed than of applying feeding force.

The device lends itself to use in polishing all manner of cylindrical rods, whether solid or hollow.

, lVe claim as our invention- In a rod-polishing accessory, the combination, substantially as set forth, of a portable standard adapted to have its lower end rest upon the floor and its upper portion supported by hand, and a pair of bearings carried side by side by an intermediate portion of said standard and adapted to receive and obliquely support the rod to be polished.
