GRINDING AND POLISHING WHEEL.
SPECIFICATION formingpart of Letters Patent No. 683,942, hated October 8, ieoi. gate... filed April 4, 1901. Serial. No. 55257. m. model.)
To all whom it may concern:
Be it known that I, DAVID B. HYDE, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements 'in Grinding and Polishing Wheels, of which the followingis a specification, reference being bad therein to the accompanying drawings.
This invention relates to grinding and polishing-wheels and is in the nature of an improvement upon the construction set forth in the application filed 'by me June 11, 1900, Serial No. 19,800.
The object of the present invention is to provide a firm and uniform gripping of the wheel by the clamping-plates; and to these ends the invention consists in certain novel features, which I will now proceed to describe and will then particularly point out the claim.
. each clamping-plate.
In the accompanyingdrawings, Figure 1 is a central sectional view of a structure embodying my invention in one'form. Fig. 2 is a View of the inner face of one of the clamping-plates, and Fig. 3 is a detail view of a modified form of the teeth or serrations.
In my prior application above referred to I have described a grinding and polishing wheel comprising a wheel proper having its sides converging toward'its outer periphery, the same being held in position on the mandrel byapair of clamping-plates having their inner faces concave to engage with said wheel on opposite sides thereof and provided with teeth or serrations formed on said plates adjacent to said wheel. In the construction therein set forth these teeth or serrations are shown as being uniformly and equidis'tantly distributed over the entire inner surface of I have found in practice that it is advantageous to arrange the teeth or serrations in groups separated by intervening spaces, there resulting from this arrangement two advantages-first, that the number of teeth being reduced the amount of pressure on each individual tooth is correspondingly increased, and the bite or hold thereof is consequently improved, and, sec-' ond, that the intervening spaces not provided with teeth serve to give a greater measure of accommodation for inequalities on the clamping-surfaces of the grinding-wheel.
In carrying out my invention Ihave shown a grinding-wheel 1, which maybe of any suitable material and which is so constructed that its sides converge toward its outer pe-, riphory. This wheel is provided with the usual opening 2 to receive the mandrel or spin dle 3, said opening being provided with a filling 4. of lead or the likein the usual manner, and the spindle being provided with a fixed collar 5, movable collar 6, and clamping-nut 7 or any other suitable means for tightening up the clam pin g-plates. The clamping-plates are indicated at 8 and are concave on their inner faces to fit the tapering wheel. The
inner face of each disk is provided with annular groups 9, composed of teeth or serrations 10, the spaces 11 being not provided with teeth. These annular groups may be of any suitable number, and the number of teeth or serrations in each group may be varied. It will be noted that the omission of teeth at the blank spaces so reduces the number of teeth or serrations 011 each disk that when a given pressure is applied to the clampheld and the device as a whole is rendered more effective. v
In Fig. l of the drawings I have shown teeth the sides of which are inclined at equal angles to the surface of the wheel with which they contact. This construction may, however, be modified, and in Fig. 3 I have shown a construction in which teeth are employed whereof those faces which are nearest the spindle are substantially perpendicular to the surface of the wheel.
teeth may be otherwise varied, and the de- The form of the tails of construction hereinbefore set forth inay be modified, and I therefore do not wish to be understood as limiting myself to the precise construction hereinbefore described,
.5 and shown in the accompanying drawings.
Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-
In a grinding and polishing wheel, the com- 10 bination, with a wheel proper having its sides converging toward its outer periphery, of a pair of clampingplates having their inner faces concave for engaging with said Wheel proper on opposite sides thereof, said inner faces being provided with annular groups of teeth or serrations formed on said clampingplates adjacent to said wheel proper and with intermediate blank or toothless spaces, sub stantially as described.
In testimony whereof I affix my signature 20 in presence of two witnesses.
