' GRINISING WHEEL Filed July 15, 1925 6 ES 2 w W Patented Apr. 29, 1930 UNITED STATES PATENT OFFICE THOMAS F. EMMINGER, OF WEST VIEW, PENNSYLVANIA, ASSIGNOR TO PITTSBURGH CLAY POT COMPANY, A CORPORATION OF PENNSYLVANIA GRINDING WHEEL Application filed July 15,
This invention relates to grinding and more particularly to an improved form of grinding wheel especially adapted for use in grinding clay blocKs and the like.
An object of this invention is to provide a grinding wheel of the type set forth which will operate more satisfactorily than those now in general use.
A further object is to provide a device of the type set forth which is provided with grinding members of such construction as to materially increase the rapidity of grinding over similar devices now in use and known to A still further object is to provide a device of the type set forth which will be easy and cheap to manufacture, simple to assemble and rugged in construction.
These and other objects which will appear obvious to those skilled in this art are accomplished by means of this invention, one embodiment of which is shown in the accompanying drawings, in which Fig. 1 is a view in elevation of a part of the grinding-wheel Fig. 2 is a transverse sectional view on the line 5-5 of Fig. 1; s
Fig. 3 is an elevation of one of the grinding members.
The particular embodiment of this invention which has been chosen for the purposes of illustration includes a wheel frame adapted to be mounted in any desired manner upon the rotary spindle 12 of a grinding machine.
The wheel frame 10 is provided with an axially extending, peripheral flange 13 forming a circular shoulder 14 on which a grinder ring 15 is adapted to seat. The grinder ring may be formed of a single casting or may be made up of any number of segmental sections. The grinding ring, whether of a single piece or of a number of sections, is clamped in position against the retaining shoulder 14: by means of wedge blocks 16 which, as illus- 1925. Serial No. 43,765.
formed on the wheel frame 10, concentric with the outer peripheral flange 13. Clamping bolts 20 extend through the wheel frame and are threaded to the wedge blocks for clamping the various members in assembled relation.
The grinder ring is provided with a plurality of radial series of openings 21 and the openings of each series are staggered with relation to the openings of the adjacent series; A shaft 22 extends through the openings 21 of each series and is clamped in position on the grinder ring 15 by a nut 23 at one end and 65 an angular arm 24 at the other which is received in a slot 25 formed for that purpose on the outer peripheral face of the grinder ring. An enclosing band 26 surrounds the grinder ring to which it is secured by any desired. means such as'screws 27 In each slot or opening 21 a plurality of toothed grinding Wheels 28 which are preferably in the form of star wheels are rotatably mounted upon the shaft 22. These star wheels are formed of steel and provide an abrading surface which is particularly advantageous for use in grinding clay blocks. The action of the steel star wheels 28 is rapid and accurate and the time of grinding is mat-erial- 1y lessened by their use.
What I claim is:
1. A grinding wheel having a plurality of openings for receiving abrading elements and provided with slots in the periphery adjacent said openings and an element supporting shaft extending through said. openings and provided with an angular end seated in said slots.
2. A grinding wheel having a plurality of openings for receiving abrading elements and provided with slots in the periphery adjacent said Openings, an element supporting shaft extending through said openings and provided with an angular end seated in said slots and an enclosing band surrounding said Wheel and covering the angular ends of said shafts. 1
In testimony whereof, I have hereunto subscribed my name this 9th day of July, 1925. THOS. F. EMMINGER.
