GEORGE W. FURROW, F TROY, OHIO.
HOOD FOR EMERY-WHEELS.
I To all whom it may concern:
Be it known that I, GnonenW. Funnow, a citizen of the United States, residing at Troy,-in the county of Miami and State of Ohio, have invented certain new and useful Improvements in Hoods for Emery-Wheels, of which the following is a specification.
My invention relates to improvements in hoods for grinding, polishing and buiiing wheels.
The object of my invention is to provide a hood which will be particularly effective in carrying away the dirt and dust incident to devices of this character, the invention being more particularly adapted for removing dust from above the work and also those particles which adhere to and are carried around by the wheel and are thrown ofi ata point where the work is applied.
Theinvention consists in the constructions and combinations of parts hereinafter described and set forth in the claims.
In the drawings: Figure 1 is a side elevation of the device embodying my invention. Fig. 2 is a vertical section on the line ww of Fig. 3. Fig. 3 a front view of the same. Fig. 4t is a top plan view of the hinged forward portion of the conduit hereinafter referred to. Fig. 5 is a section of the same on the line y-y of Fig. d.
Like parts are represented by similar charactors of reference in the several views.
In the said drawings, a and (1 represent the hood of my improved device, preferably formed in two parts hinged together at a in the usual manner.
a represents a grinding, polishing or buding wheel mounted upon one end of the shaft 0; which is supported in suitable bearings on the'standard a The hood or casing extends about the wheel except for the open portion at the forward end and has attached at its rear end a conduit a which may be connected to any suitable form of suction fan in the usual Way.
Located in the upper and rear portions of the hood is a division wall 6 which extends from side to side of the hood so as to form a conduit 6 which communicates with the conduit a the conduit 72 beginning at the forward part of the hood immediately above the work and being adapted to receive the dust and dirt, which will be carried rearwardly through the same into the main conduit a.
It has been common in devices of this kind Specification of Letters Patent.
Application filed February 21, 1910. Serial No. 545,079.
Patented as a, rare.
to leave an open space between the wheel 4 i and the upper part of the hood and it has. I
by the current of air created by the revolution of the wheel.
To compensate for the wear on the wheel and also for difierent sized wheels, I have the forward part of the division wall, 6, in the nature of a hinged portion, 0, pivotally supported at c to the forward part of the division wall proper. A thumb-screw extends througl'i the slotted opening 0 in a side of the hood and engaging an ear or lug 0 on the hinged portion, furnishes the means for holding this hinged portion in any. position of adjustment with respect'to the wheel. I also slidingly mount in suitable guides (Z on said hinged portion a sliding shield 03, which may be held in any position of adjustment with respect to said hinged portion 0 by the said screw (i This shield, (Z, may be slid down to any position desired with respect to the wheel and prevent the small particles which adhere to the wheel from flylng up into the face of theoperator.
Having thus described my invention, I claim:
1. In a device of the character described, a wheel, a hood, for said-wheel formed with a work opening at the forward portion thereof, and a conduit 'in' said hood closed to the wheel and extending upwardly over said wheel, substantially as specified.
2. In a device of the character described,
a wheel, a hood for said wheel formed with I a work opening at its forward portion, and a conduit in said hood closed to the wheel and extending upwardly over said wheel,
said conduit beginning at a point coincident with said work opening, substantially as 3. In a device of the character described,
' a wheel, a hood for said wheel formed with thereof, a'conduit in said hood closed to the Wheel and extending upwar 1y oveI-szt'id Wheel, and an adjustable hinged portion at the forward end of said conduit, substan' 5 tially as specified.
4. In a device of the character described, a Wheel, a hood for said Wheel, and a conduit formed in said hood' extending upwardly over said Wheel, saidconduit hav- 10 ing an adjustable hillgdTOllllOIl at the for- Ward end if reef, and an adjustable shield carried by s m. hinged portion, substantially as specified.
In testimony whereof, I have hereunto set my hand this 10th day of February, 1910.
GEORGE W. FUBROW.
