SPECIFICATION forming part of Letters Patent No. 317,622, dated May 12, 1885.

Application led October 31, 1884. (No model.)

lb au whom it may concern.-

Beit known that I, JOHN G. BUZZELL, of Lynn, in the county of Essex and State of Massachusetts, have invented a new and useful Improvement in AbradingDisks, which will, in connection with the accompanying drawings, be hereinafter fully described, and specifically defined in the appended claims,

This invention has for its object certain improvements in disks which are more especially intended and adapted for evening and smoothing the breast of boot and shoe heels, and bufting or removing the grain from the shank, and it will, in connection with the accompanying drawings, be hereinafter more particularly and fully described and claimed.

In said drawings, Figure l is a side elevation of my improved disk, shown as mounted upon an arbor. Fig. 2 is a longitudinal scction taken as on line :t fr, Fig. 3. Fig. 3 is a front elevation taken as at the left of Fig. l and right of Fig. 2. Fig. 4 is a rear elevation taken as at the right of Fig. I and left of Fig. 2.

In these views, A represents the body of my disk, formed preferably of wood and secured on arbor B by means of the flanged bushing c, in a well-known manner, as shown in Figs. 2, 3. Upon the cuter face of this disk I secure the felt cushion b, in a manner common and well known, and upon this cushioning-disk I mount the disk c,ofsandpaper or emery-cloth, and I detachably secure such abrading-disk upon the cushion by means of the hooked elastic arms or wires d, which at their converging ends are rigidly secured in the flange of sliding disk e, mounted on arbor B, and forced from, disk A by the expansive action of coiled spring f, mounted on `said arbor, the outer or diverging ends of arms d being reduced and bent hook-like, as shown in Figs. 2, 3, so as to compress at their point of contact therewith by the action of spring f the sand-paper into the cushion, so that the operative face of disk c will be outside or" said hooks, thus preventing said hooks from coming in contact with the surface which is being abraded. Said cushion b and abrading-disks c may extend entirely across the face of body A, or a central portion may be cut out, as shown, both being equally well-kuown methods.

I form the peripheral face ol'nly disk oblique to its axis, as shown in Figs. l, 2, and with guard or support, f1', at the inner or converging part of said oblique face, and I cover said face with a cushioningband, g, on which I mount the abradingband h, said band It being in a well-known manner cut with the requisite edge curvature to iit smoothly upon the peripheral face ci" cushion g, it being held in position by its edge bearing against said guard t', which extends outward l'roin the peripheral face of cushion Q0, i ust sufficiently to secure the sand paper in place. If desired, sand-paper h may be stretched and secured in position on the disk by means of a hinged binding-section, j, (shown in Fig. 4,) and which is a common and well-kno wn device for such purpose. The arms d are by means of their converging elas* tic pressure embedded in peripheral cushion g, so as :not to interfere with the operation of the abrading-covering hv when in use. By the use of said abrading-band h the concave breast of the heel may be scoured smooth and even without bringing disk c in contact with the sole or bottom, and then while the shoeis still in the hands of the operator the shank may,it` desired, be scoured and buffed by the action of face or disk c. When the sand-paper disk c becomes worn by use and it is necessary to replace the same, the operator has only to slide sleeve c toward disk A, so as to-loosen the hooks oi arms d from said disk c, when it can be instai'i'lly dislodged and replaced by a new one.

well known to :mount a disk of sand-paper upon the cushioned face or plane of a rotary..i

disk, and I am also aware that it is equally well known to mount a band of sandpaper upon the periphery of a rotary disk or roll; hence I claim neither, broadly, or in the abstract, my invention consisting in the method and means of securing the disk of saudfpaper in place upon the plane ofthe cushion, in a disk having a peripheral face oblique to its axis and with a guard to prevent displacement of the band of sand-paper, and in the resulting combinations; hence I claim as my invention- 1. In combination with an abrading-disk, a series oi" arms arranged around the periphery I CO said arms may be lineally adjusted and re-.

tracted, to press said abrading-eover against its cushioning-support, substantially as specied.

2. In combination with disk A, the arms d, sliding sleeve e, and spring,` all substantially as specied.

3. An abrading-disk formed with a cush ioned peripheral face oblique to its axis, and with a circumferential guard, i, adapted to sustain the abrading-band h and secure it in position upon the disk7 substantially as speci- 15 ripheral face oblique to the axis of 4the disk 2o and provided with a circumferential guard, whereby the abrading-band is secured in position thereon, substantially as specified;
