ELASTIC COLLAR FOR POLISHING AND GRINDING WHEELS. APPLICATION FILED APR. 30. 1920.

' wam ATTORNEY GILDEROY O. BURLEW, OF NEWARK, NEW JERSEY.
ELASTIC COLLAR FOR POLISHING AND GRINDING- WHEELS.
To all whom it may concern.
Be it known that I, GILonRoY O. BURLEW, a citizen of the United States, residing in the city of Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Elastlc Collars for Polishing and Grinding Wheels, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it pertains to make, construct, and use the same, reference being had to the accompanying drawings, and to numerals of reference marked thereon, forming a part of this specification.
My invention relates to elastic collars for polishing, grinding or other abrasive wheels, and the main object of the invention is to provide a yielding bearing for a wheel,
thereby preventing undue shaking or trembling of the wheel and the support upon which it is mounted, at the same time allowing the wheel to is met.
The application of the elastic collar to the sides of the wheel imparts to the periphery of the grinding wheels, a certain amount of resiliency, thereby absorbing and taking away much of the shock from the work and the operator.
These objects I perform in the preferred embodiment of my invention, which I have illustrated in the accompanying drawings, to which reference is had, and in which similar characters of reference indicate corresponding parts in the several views.
In the accompanying drawings forming a part of this specification,
Figure 1 represents, an axial section of a yield when undue resistance grinding wheel provided with my improved collars. I Figs. 2 and 3 represent, inner face views of two different forms of collars, and
Figs. 4 and 5 represent, sectional views thereof.
In the drawings, 1 represents an abrasive wheel, which may be an emery or other abrasive wheel, grinding or polishing wheel,
provided with the usual central hole 2 for the reception of the arbor or spindle 3.
A rubber collar 4 is placed at each side of the wheel, provided with a central hole 5 to receive the arbor 3, and said collars are held in place by metal washers 6 on the Specification of Letters Patent.
Application filed April 30, 1920.
'fPatented Aug. 59, 1921.
Serial No. 377,839.
spindle, 3 and nut 7 which hasscrew threaded engagement with the screw threaded end of the arbor 8.
The'inner faceof therubber collar 4L (illustrated in Fig. 2 of the drawings, which shows the preferred form of my invention) is provided with gripping means, said gripping means, consisting of a plurality of recesses8, preferably concaved and which are formed in the collar during the process of the manufacture of the same.
These concaved recesses 8 which may be of any other convenient shape act as vacuum cups, so that when the collars areclamped at each side of the wheel by means of the metal washers 6 and the nut 7 the wheel is resilient[l y1 mounted and prevented from turning. in Fig. '1 of the drawing assuming that two collars like-the one illustrated in Fig. 2 are used, permits the wheel to be suspended and resiliently clamped between the washers free from the spindle. 1 v
In actual practice I have also found the rubber collar 4 illustrated inFig. 3 of the drawings, which is provided with a plurality of inserts 9 made of cork projecting slightly beyond the inner face of the collar, very eificient. This collar may also be provided with a tubular projection 10 designed to be received in the central hole 2 of the wheel 1.
The collar illustrated in Fig. 2 of the drawings may also be provided with this tubular projection 10 if desired. When the tubular projections 10 are not, employed on the collars, there'is a small space between the spindle 3 and the wall of the central hole 2, and whenso mounted considerable resiliency is imparted to the periphery-of the grinding wheel, thereby absorbing and taking away much of the shock from the work and the. operator. 7
The same result is obtained when the collars provided with are used.
Experience has demonstrated that the organization. above described is a highly eflicient one, and while I have shown the pree parts whenin the position indicated the tubular projection '10 by any skilled mechanic, and such departures from what is herein set forth, I consicer within the scope and terms of my claims.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is: I
1. In a grinding and polishing wheel, the combination of a pair of apertured rubber clamping collars upon opposite sides thereof,
the inner face of each collar being provided with a tubular projection, and further provided with a plurality of gripping means located between said tubular projection and the periphery of said collar.
2. In a grinding and polishing wheel, the combination of a pair of aperturedrubber clamping collars upon opposite sides thereof, the inner face of each collar being provided with gripping means, said means comprising a plurality of recesses.
3. A new article of manufacture comprising an apertured rubber collar, one face of said collar being provided with gripping means.
a. A new article of manufacture comprising an apertured rubber collar, one face of said collar being provided with a tubular projection and with gripping means.
This specification signed and witnessed this 27th day of April, 1920.
