HOOD FOR BUFFINGr-WI-IEELS.

Specification of Letters Patent.

Patented Mar. 13, 1917.

Application filed. April 21,1916. Serial No. 92,785.

To all whom it may concern.

Be it known that we, WILLIAM M. HAUSER and JAMns McDANIE citizens of the United States, residing at Evansville, in the county of Vanderburg and State of Indiana, have invented certain new and useful Improvements in Hoods for Buffing-lVheels, of which the following is a specification.

Our invention relates to hoods for buffing or grinding wheels.

The object of our invention is to produce a hood of the character described adapted to partially surround a buffing or grinding wheel of ordinary construction and recover the particles of metal that are cut from the article ground upon the wheel. A further object of our invention is to produce a hood adapted to protect the operator from the flying particles and to draw such particles away from the operator and to deposit same in a receptacle in which same may be conveniently removed. A further object thereof is to produce an article of the character described adapted to be conveniently adjusted to accommodate the character and size of the article to be ground. A still further object thereof is to produce a hood and suction device adapted to deflect particles produced from the grinding wheel from the face of the operator and deposit same in a receptacle from which they may be removed: and a still further object of our invention is to produce a more-simple, cheap and efficient hood of the character described than has heretofore been attained.

To these ends our invention includes the combination and arrangement of component parts to be hereinafter described and more particularly pointed out in the claim.

On the accompanying drawings, in which like reference characters indicate similar parts:

Figure 1 is a side view of our invention.

Fig. 2 is a vertical sectional view.

Fig. 3 is a front view, and

Fig. 4 is a back View.

Referring to said drawings, 1 indicates a grinding wheel of ordinary construction and 2 designates a hood adapted to surround the major portion of the wheel, leaving a minor portion thereof 3 exposed to the operator. As shown in the drawings, the rear face of said hood is closed while the front thereof is entirely open to permit access to the exposed portion of the perimeter of the grmding wheel. Said hood may be ad usted to 1 containing the particles produced from the grinding operation.

Intermediate of said chamber and recep tacle and the hood proper the suction pipe 14 communicates with the draw pipe 11 at right angles thereto at its upper wall, although as shown in the drawings, the lower contacting walls form an acute angle at 15 which is also somewhat offset from the vertical line of the draw pipe 11.

A suitable suction wheel, not shown in the drawings,,is provided for the suction pipe 14, whereby a constant flow of air is produced from the opening in the face of the hood through the suction pipe 14, which suction draws the particles produced on the grinding wheel inwardly and downwardly toward the suction pipe 14 and awayfrom the face of the operator. It will be further obvious that a partial vacuum will occur in the chamber 12 beneath the right angular connection between the-draw pipe 11 and the suction pipe 14 and thatin making the turn from the draw pipe into the suction pipe the particles produced by the grinding or loufling wheel are likely to fall into chamber 12 I rather than be drawn at right angles into the suction pipe 14.

The receptacle 13 is adapted to be supplied with water for the purpose of retaining said particles and may be removed from the chamber to recover the particles deposited therein.

From the foregoing description and by reference to the accompanying drawings it will be appreciated that the hood of our invention may be conveniently adjusted to accommodate same to the nature, character and size of the article to be treated on the grinding or buffing wheel, and that the particles produced by the operation may be retained and recovered in the receptacle 13 through the partial vacuum created in the chamber 12 and the diminution of the force of the suction from the pipe 14 at the right angular turnformed with the draw pipe 11.

' draw pipe connected with said hood sections 15' beneath the wheel, a vacuum chamber at the base of said draw pipe, a suction pipe c011- nected with said draw pipe intermediate of said hood and vacuum chamber at right angles to the draw pipe, and a removable receptacle carried in said vacuum chamber for the reception of particles produced bygrinding, substantially as described.

In testimony whereof we hereby aflix our signatures in the presence of two witnesses.

WILLIAM M. Hansen. JAMES MODANIEL.
