GEORGE W. OSBOBN, 0F BEDFORD, OHIO.

EMERY-WHEEL DRESSER.

Application filed February 19, 1920. Serial No. 359,768.

To aZZ whom it may concern Be it known that I, GEORGE V. OsBORN, a citizen of the United States, and resident of Bedford, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Emery-Wheel Dressers; of Which I hereby declare the following to be a full, clear, and exact description, such as Will enable others skilled in the art to which it appertains, to make and use the same.

The objects of the invention are to provide an improved construction of tool for dressing emery wheels and the primary object is to provide a detachable guard which is mounted upon the handle of the rotatable cutter.

This guard is an important feature of the invention since it protects the face and eyes and also the hands of the operator from flying sparks and grit and makes the operation of dressing the emery Wheel a much easier and cleaner one in every way.

The device comprises the forked handle, the revolvable cutter mounted between the sides of the fork, a pivot shaft or pin )assingthrough the cutter and upon which t e cutter revolves, a hood slidable upon the handle and cutter pins or other securing means engaging the hood and preventing its movement and also engaging the aforesaid pivot shaft and preventing it from falling out of its place in the fork of the handle.

The invention is illustrated in the accon1- panying drawings, hereinafter more fully described and specifically pointed out in the claims.

In the accompanying drawings Fig. l is a perspective of the device; Fig. 2 is a trans verse section thereof on the center of the pivot shaft.

Fig. 3 is a perspective of the pivot shaft showing lateral openings to receive the hold in pins. I

%ig. l is a perspectlve of the protecting hood or cap.

In these views A is the handle forked at B. In the arms of the fork is secured the pivot shaft C upon which the cutter D revolves freely.

The upper longitudinal edges of the arms of the fork overhang to form horizontal guides E and a hood F is slidably movable over the guides to its position over the upper and rear portions of the cutter by means of channelled edges F movable upon said guides.

When in position, both the hood and pivot shaft are rigidly secured in place by means of detachable pins such as split pins G, G, which pass through openings in the lugs 1 upon the hood and also through openings K, K; openings J, J, in the fork and openings L adjacent to the extremities of the pivot shaft.

These spring pins can easily be Withdrawn if the use of the hood is not desired and the hood removed.

Having described the invention what I claim as new and desire to secure by Letters Patent is:

1. In an emery Wheel dresser, in combination a forked handle, a shaft mounted in the arms of the said fork, a cutter revolvable upon said shaft, a hood having channelled longitudinal edges, and guides upon the longitudinal edges of said fork, in Which said channelled edges of said hood are slidingly movable.

2. In an emery WllG'dl. dresser, in combina tion, a forked handle, a shaft therein, a cutter revolvable on said shaft, ahood slidahle upon said arms over said cutter, and having lugs on its base and detachable pins passing through said lugs, arms and through portions of said shaft adjacent to the extremities thereof.

In testimony whereof, I hereunto set my hand this 16th day of January. 1920.

GEORGE W OSBORN.
