IMPROVEMENT IN ELASTIC CLAMPS FOR POLlSHING AND GRINDING WHEELS.
Specification forming part of Letters Patent No. 158,617, dated January 12, 1875 application filed 'June 6, 1874.
To all whom it may concern: 1
Be it known that we, Bonn, BANNISTER, JOHN G. PERKINS, and WILLIAM H. Sron- DARD, of Kalamazoo in the county of ,Kalamazoo, and State of ichigan, have invented wheels, wherein it is desired to allow such wheels to center themselves automatically. The invention consists in the employment, in combination with an elastic center, an emery, or grinding wheel and elastic side clamps, of two dished (clamping-collars, one of which is constructed with a'sleeve, which passes through the said elastic center, and receives upon it the other movable collar, the whole being rigidly confined by means of a mandrel and a nut, as will be hereinafter explained.
Inthe annexed drawings, A designates a grinding-wheel, which may be composed inwhole or part of emery or other suitable substance, with a hole centrally through it. In this hole is confined a circular flanged eyepiece, J, which is composed of indie-rubber, and which is held ill-place by means ot' its flanges. O G" designate two clamping-collars of any required diameter less than the diameter of the wheel A, which collars are constructed with rims c on their edges that give them-adished shape, as shown in Fig. 1. The
collar 0 has constructed centrally on it a sleeve or tube, I, which is passed through the center of the eye-piece, J, and which receives through 1t a mandrel, M, having a shoulder, a, on one end, and a screw-thread on the other end. R R designate two elastic rings of in-' dia-rubber, whose interior diameter is such that they receive into them the flanges on the eyepiece J, and whose exterior diameter is such that they are received snugly in the clamping-collars 0G, and prevented from dis placement by the annular rims or flanges c a of these collars. When the eye J is adjusted in the center of the wheel A, the clampingcollars are applied to this wheel with the elastic rings R It between them and the wheel A,
the mandrel M is inserted through the collar (J and sleeve I and collar 0', and through the said eye J, and receives on its end the nut N,
by screwing up which the collars O O and the intermediate rubber rings It It will be firmly clamped to the sides of the wheel A.
The advantages derived from this form of clamp are as follows, to wit: The bearing upon the mandrel is greater than the thickness of the wheel, being the thickness of the wheel with the additional thickness of the body of the clamps or collars. The benefit gained is a greater bearing-surface when in use'on the mandrel. The clamping-collars, when adjusted to the wheel, being a part of this wheel, can be taken from the mandrel.
and mounted without'centerin g or turning up the wheel ateach change. This form of clamp, when once fitted to the wheel, remains with the wheel. Theclamp 0 and thimble I being made of metaha very accurate fit t0 the mandrel is obtained. In screwing up clamp 0 it is guided centrally by the thimble or sleeve, and will adjust itself perfectly. to the wheel, and bring all the parts in proper place.
What we claim as new,'and desire to secure by Letters Patent, is-,-
' The clamping-collar 0, formed entire with v the sleeve I, and receiving through it the mandrel M, in combination with the elastic eye J, elastic rings 1%. R; loose collar 0, and clamping-nut N, and with the grinding-wheel A, substantially as described.
In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.
' BUBR BANNISTER.
