EMERY-WHEEL.
SPECIFICATION forming part of Letters Patent N 0. 760,957, dated May 24, 1904. Application filed July 10, 1903. Serial No. 165,012. (No model.)
To all whom it may concern.-
Be it known that I, JOHN W. CLARKE, a citizen of the United States, residing at Bay City, in the county of Bay and State of Michigan, haveinvented anew and useful Emery-Wheel, of which the following is a specification.
My invention relates to emery-wheels, and has for its object to produce a device which will be simple of construction, efiicient in operation, and one which may be readily applied to and operated by the hand-wheel of a sewing-machine and which in practice will readily adjust or center itself upon the sewing-machine wheel, thus rendering it applicable to wheels of varying sizes.
To these ends the invention comprises the details of construction and combination of parts more fully hereinafter described.
In the accompanying drawings, Figure 1 is a view in elevation, illustrating my improved device applied to the wheel of a machine.
Fig. 2 is a detailed sectional view of the same.
Referring to the drawings, 1 indicates my improved emery-wheel composed of any suitable material, but preferably of wood, and having an abrading-surface 2, formed by applying to the periphery of the wheel a coating of a suitable emery or like compound. The emery-wheel is provided with a central opening 3 and has one of its faces concaved to receive the rim of the sewing-machine wheel 4, as illustrated more clearly in Fig. 2.
5 indicates a series of clamping devices, preferably three in number and in the form of rubber or leather straps, secured to the side of the wheel near its periphery by screws or other suitable fastening devices and adapted to engage at their inner ends over headed studs 6, projecting from the inner wall of the wheel formed by its central opening In practice the emery-disk will be made of such size that it will readily accommodate the largest-sized hand -wheels now in use upon sewing-machines and When mounted upon the sewing-machine wheel will be secured in place by means of the fastening devices 5, which are so disposed around the disk that the same will when applied to smaller-sized wheels, or, in other words, wheels which do not fit accurately and snugly in the concavity of the disk, aiitonliatically adjust or center the disk on the w ee From the foregoing it will be seen that I produce a simple device which may be readily applied to sewing-machines and operated for grinding small tools or for polishing silverware or the like, in which latter case a piece of felt, chamois, or the like will be wrapped around the disk over the abrasive surface.
Having thus described my invention, what I claim is 1. An emery wheel comprising a disk adapted to be applied to a sewing-machine wheel, and having an abrasive surface, and a plurality of flexible straps disposed equidistantly around the disk and adapted to embrace the wheel and automatically center the disk thereon, said straps each having one end secured to the disk and its other end detachably engaged therewith.
2. An emery wheel comprising a disk adapted to be applied to a sewing-machine wheel and having a concaved face to receive the wheel and an abrasive surface, and a plurality of flexible elastic straps disposed equidistantly around the disk and adapted'to embrace the wheel and automatically center the disk thereon, said straps each having one end secured to the disk and its other end detachably engaged therewith.
3. An emery wheel comprising a disk adapted to be applied to a sewing-machine wheel and having a concaved face to receive the wheel and an abrasive surface, said disk being provided with a central opening bounded by an inner marginal wall, fastening devices carried by the concaved face of the disk, engaging members carried by the inner marginal wall, and a plurality of flexible elastic straps disposed equidistantly around the disk and adapted to embrace the wheel and automatically center the disk thereon, said straps each having one end secured to one of the fastening devices and its other end detachably engaged with one of the members.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
JOHN W. CLARKE.
