This invention relates to grinding `wheels.
and means for mounting the same. The object being to provide a grinding wheel for general purposes and a mount therefor whereby work can be passed entirely across the outer face of said wheel when ink operation. Said mount having means whereby the wheel may be accurately centered thereon and quickly removed when desired.
Features of the invention are present first, in providing the grinding wheel with side depressions having flaring or beveled side walls the depressions in the outer face or side O' the wheel being preferably of a depth greater than that in the opposite face.
Further features of the invention arek found in an arborv having a conical shoulder and an extended vcircularflange and cheek pieces, plates or disks having flared peripheral edges and inwardly converging central portions providing conical sockets or chambers teiminating in short sleeves bearing on said ar or.
The outer end of the arbor terminates within the plane of the outer face of the wheel and is provided with short spiral grooves on which a nut, having a conical inner face and a circular flange, is threaded, said nut having wings or projections by which it may be loosis to be removed.l
The invention possesses other advantageous features, which, with the'foregoing will be set forth in the following description and it will be understood that I do not limit my-v self to the construction shown as I may ladopt many variations within the scope of the invention claimed.
In the drawings forming part of this specilisation similar characters of reference are employed to designate corresponding parts throughout the several views, in which:
Fig. 1 is a central vertical sectional elevation of my improved emery wheel andthe means for mounting the same, the locking nut being indicated as removed in dotted lines,
Fig. 2 is an outside face view of the device,
Fig. 3 is a detail side elevation of a portion of the arbor'. Y
ened and turned oif the arbor when the wheell Referringl tothe drawings in detail, liOiin-y dicates the'improved grinding wheel made Of emery or otherjma'terlal7 having a central bore 1l, and recessesor depressions 12 and 13,l
formedin the'opposite sides .thereof and it is preferably i reinforced against-k high i speed centrifugal'strains-by-a disk or sheet of heav7 wire jmeshfllt moulded into the wheel structure as shown. Y Y i. p.
In earrying'out my invention, I provide an arborv 15', formed with anV integral-circumferenti-al' shoulder;16formedwith an extended flanged? and a conical face portion 18,. To properly center or balance the grinder wheel 10 onits arbor 15..I provide companion cheekdisks, plates or pieces 19, which maybe stamped or formed with flared peripheral edges 2O to fitsnugly within the iaredwalls 2 1 of the depressions orrecesses 12 and 13 at the opposite sides of the Wheel, as shown in Fig.y ly of vthe drawings. f i vThe Vdisks 119are pressed inwardly at their centers A.producing inwardly converging or flaring portions. 221, terminating in shortA sleeves 23 which bear on yand enclose kthe ar` bor 15..` rlhe converging portions. 22 of the disks 19 provide conical sockets or chambers 24 and2 adaptedito receive iniintimate relation, the conical face portion 18, offthel arbor anda coineior conical face portion 26 of a nut.27 i: ,17. *I I Y The free yor outer end of the arbor 15, isk preferably provided with spiral grooves or channels 28, to receive kcorresponding spiral threads or ribs 29 in the bore of the nut as shown in F 2 of the drawings.
To facilitate the vremoval of the nut by backing up on the threads, I provide it with wings1 lugs or projections 30. against which a hammer or other tool may be tapped lightly to start the backward movement.
It will be noted that the spiral grooves eX- f tion of spiral of the grooves being in the direction of rotation of the wheel, so' that the nut is constantlyj ammed down into clamping*k relation with the parts.
The nut 27 has also formed therewith a circumferential flange 31, corresponding to the flange 17 on the arbor shoulder 16, which flanges normally bear against the plates 19 outwardly of the conical chambers 24 and 25 when the parts are assembled. Adjustments can be made by placing shim rings or pieces back ofthe said flanges as will be understood.
Having thus described my invention, what Ivclaim and desire to secure by Letters Patent is:
1. A grinding wheel having a central bore and recesses at its opposite sides, the recesses having flat parallel bottoms and outwardly flaring straight circumferential Walls, in conibination with means for mounting said wheel, comprising companion cheek plates each having a straight peripheral flaring flange to intimately engage the flaring wall of its corresponding recess, a flat body portion, a conical socket having a central opening and Y a unitary inwardly directed sleeve, the conical socket and `sleeve of each cheek plate extending within the wheel bore at both ends thereof, an arbor having a conical shoulder to engage the socket of one cheek plate and a nut having a conical shoulder to engage the socket of the opposite cheek plate for clamping the said plates to center and support said wheel.
\ 2. A grinding wheel having a central bore and opposite circular depressions provided With outwardly flaring straight circumferential walls, in combination with cheek plates shaped tointimately engage said walls and having conical sockets with central openings and unitary sleeves projecting inwardly from either end of said bore, an arbor and a clamping nut, each having a conical portion to fit said sockets and an extended circumferential flange bearing against the bottom of the recesses at the edge of said bore as shown and described.
In testimony whereof, I have signed my name to this specification, this 27th day of January, 1928.
