GEORGE E. DUNHAM, OF LYNN, MASSACHUSETTS, ASSIGNOE OF ONE-HALF TO JOSEPH B. JOHNSON AND ARTHUR FULLER, OF SAME PLACE.

BUFFlNG-WHEEL.

SPECIFICATION forming part of Letters Patent No. 240,395, dated April 19, 1881.

Application filed February 26, 1881. (No model.)

To all whom it may concern:

Be it known that I, GEORGE B. DUNHAM, of Lynn, of the county of Essex and State of Massachusetts, have invented a new and useful Improvement in Buffing-Wheels; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figures 1 and 2 are opposite side views,

Fig. 3 a front elevation, Fig. 4 a vertical and transverse section, and Fig. 5 a longitudinal section, of a butting-wheel containing my said invention, such wheel being forthe purpose of buffing the edges of the heels of boots or :5 shoes. Fig. 6 is an inner side view of the adjustable gage and its clamp-screw and standard, to be hereinafter described.

The natureof my invention or improvement is duly set forth in the claims hereinafter made. In the drawings, A denotes a wheel having but one head, a, such wheel being chambered concentrically, as shown at b, and provided with a mouth or opening, 0, leading obliquely through the periphery or rim dinto the chamher I). The head of the wheel extends beyond the rim of the wheel, so as to form a gageflange, e, that has a diameter sufficient to cause it (the said flange) to project a short distance beyond the abrasive surface of the wheel. The

0 sides of the oblique mouth or opening 0 are provided with yielding or elastic lips fg, which are fixed to the inner periphery of the rim, and extend through the mouth and beyond it a short distance, as shown. ,From one of these 3 5 lips to the other there is arranged around the outer periphery of the rim a yielding strip of cloth or cushion, h, around which there is carried an abrasive ribbon or strip, *5, which may be of what is termed sand or emery paper, or be a tape or ribbon covered on its outer surface with an abrasive powder or material. The ends of the cushion or strip of cloth h abut directly against and are supported by the yielding or elastic lips f g, they reaching to,

4 5 or nearly to,the outer periphery of the cushion. They thus not only prevent extension of the cushion at its ends, but are of further advantage, as hereinafter explained. The strip is wound upon a spool, B, having a single head,

k, of a diameter sufficient to enable the head to serve as a cover to the chamber of the wheel.

The spool is to turn freely on the shaft or arbor l of the wheel A. The abrasive strip wound. upon the spool is led therefrom out through the month 0, and is thence wound upon and. 5 around the cushion h, and has its free end passed into the mouth and a short distance into the chamber. On thespool being revolved in the proper direction, the strip may be drawn tightly upon the cushion.

Besides the spool upon the arbor there is a driving-pulley, O, that has in it a screw, m, which screws into it and against the head of the spool. Besides the said screw, there is another screw, it, that screws into the hub of the pulley and against the arbor. This latter screw serves to clamp the pulley to the arbor, the screw m answering to prevent the spool from revolving so as to loosen the abrasive strip on the cushion.

The buffing-wheel so made has the journals 010 of its arbor supported in bearings in the upper parts of two standards, E F, erected upon a base, G; and at the side of the wheelhead there is arranged, as shown, an adjusta- 7 Die gage, H, which is to prevent the wheeltla-nge from penetrating the space between the shoe back and the heel far enough to reach their confining-stitching, to the injury thereof. This gage is composed of a curved are, r, of metal, and a supymrting-arm, 8, arranged as shown. There is in the arm a slot, t, to receive a clampscrew, u, for fastening the arm to the next adjacent standard. By means of the slot and screw the gage can be properly 8 adjusted relatively to the periphery of the wheel-flange.

In using the wheel a person holding a shoe in his hands is to present it to the wheel in a manner to cause the flange thereof to enter the joint between the heel and the back with the latter against the adjustable gage, the edge of the heel being against the buffing-surface of the wheel. This surface being put in rapid revolution, the person holding the shoe is next 5 to turn it in a manner to cause the curved edge of the heel to be carried around in contact with the abrasive surfaceof the wheel, which, acting on the edge while the shoe is being so turned, will reduce or buff it, as may be refoo quired.

- It will readily be seen that, with the wheel made as described and provided with the spool, the strip, as it may become worn, may be unwound and have the worn part removed from the rest and a fresh portion substituted on the wheel.

The elastic or yielding lips answer while the wheel is in action to clamp the strip in the mouth 0 and to make a close joint between the parts that are therein, and also to prevent the mouth from being stopped by the cushion in case it should become elongated. By being elastic the lips yield with the cushion as well as support it at its ends while the wheel may be buffing a heel.

What I claim as my invention is as follows:

1. The combination of the chambered wheel provided with a strip-receiving mouth in its rim with the rotary spool arranged on the arbor and to extend into the chamber of the wheel, as and for the purpose set forth.

2. The combination of the chambered wheel provided with the rim mouth and flange, arranged, as described, with the rotary spool arranged on the arbor and to extend into the chamber of the wheel, as and for the purpose set forth.

3. The combination of the driving-pulley and its clamp-screws, arranged in it, as described, with the wheel and its arbor and the spool, substantially as set forth.

4. The combination of the abrasive strip and its supporting-cushion with the wheel and with the rotary spool arranged on the arbor and to extend into the chamber of such wheel, substantially as explained.

5. In combination with the buflingwheel and its surrounding cushion, the elastic lipsf 9, applied to the rim of the wheel and the openin g thereof, and arranged to extend up through such opening and in front of and against the adjacent ends of the elastic cushion, so as to serve as yielding abutments thereto, all being substantially as described and represented.

GEORGE B. DUNHAM.
