ABRASIVE WHEEL.

Application filed February 4, 1927. Serial No. 165,945.

This invention relates to abrading tools, and its general object is to provide an abrasive Wheel of the abrasive band receiving type, that is capable of receiving or having removed therefrom a seamless band of abrasive material in an eflicient and expeditious manner and with very little efiort on the part of the operator.

A further object of the invention is to provide an abrasive wheel that includes a soft, resilient material underlying the abrasive, material, so that the abrasive material will give to the work and be suitable for use on allkinds of work.-

Another object of the invention is to provide a grinding wheel of the circumferential split type adapted to receive a resilient band and an abrasive band and which is held associated without the use of bolts, nuts or other like fastening means, with the result, damage caused by casual separation of the parts, as well as flying nuts and bolts, has been entirely eliminated.

Another object of the invention is to provide an abrasive wheel of the character set forth, that is extremely simple in construction, strong and sturdy, and inexpensive to manufacture.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a side elevation of the abrasive Wheel which forms the subject matter of the present invention and showing the same applied to the drive shaft of a power unit. K

Figure 2 is a front elevation of the wheel.

Figure 3 is a sectional view taken on line 33 of Figure 2.

Figure 4 is an edge view illustrating the manner of removing or applying an abrasive band to the resilient band of my wheel.

Referring the drawings in detail the wheel proper includes circumferentially divided sections 1 and 2, each of which includes cooperating inwardly inclined rim portions 3 and 4 having formed on their outer ends annular flanges 5. Each of the sections also include disk portions 6 and 7 formed with hubs 8 as best shown in Figure 3 of the draw1ngs. The disk portion 6 of the section 1 is provided with a plurality of openings 9 for a purpose which will be presently described.

As shown in Figure 3 as above set forth, the rim portions 3 and 4 are inwardly inchned toward each other and are adapted to receive a resilient band 10 having its inner face which is covered with a leather band 11, sloped inwardly and toward its center so as to be accommodated by the rim portions, and by this construction, it will be obvious that when the respective sections are associated with the resilient band which has a normal diameter slightly smaller than the sections, therefore, the sections will cause the resilient band to expand and therefore hold the. abrasive band 12 taut thereon as -W1ll be readily apparent. The resilient band proper is formed from rubber or other like resilient material and is reinforced through its central portion by fabric drilling or the like 13, and a wire mesh 14 which is disposed outwardly of the drilling as shown in Figure 3 of the drawings. The flanges 5 provide stops and function -to prevent casual lateral movement of the resilient band.

The hub 8 formed by the respective sections is provided with a transverse groove or key way to accommodate the usual key 15 so as to revent slippage of the wheel upon the tool s iaft, and the usual nut 16 is adapted for securing the wheel to the shaft as best shown in Figure 3 of the drawings.

From the above description and disclosure of the drawings, it will be obvious that I have provided an abrasive wheel adapted to receive a seamless abrasive band which is frictionally held in operative position upon the resilient band 10 and when it is desired to a ply the abrasive band to the resilient ban the latter is arranged in the manner as shown in Figure 4 which will allow easy applicationof the resilient band thereto. The same action is resorted to when it is desired to remove a worn abrasive band from the resilient band. When the abrasive band 12 is applied to the resilient band as above set forth, the latter is then applied to the respective sections 3 and 4 which are frictionally held in cooperative association until the wheel in its entirety is secured to the driving shaft of the power unit in the manner as shown in Figure 3. When it is desired to remove the sections from the resilient band, a nail or a tool capable of fitting in one of the openings 9 of the section 1 can be passed through the opening and caused to contact with the opposite section for pushing the same from the band and of course the first mentioned section 1 can then be readily removed as will be obvious.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scopeof the appended claims.

What I claim is:

1. An abrading wheel of the character described comprising circumferentially divided sections adapted to be associated to form the wheel, one of said sections being provided with openings, a resilient band adapted to surround said sections when associated, a flange formed with each section and adapted to cooperate for retaining the resilient band on said sections, a flexible hand between the sections and resilient band, a fabric drilling for reinforcing said resilient band, an abrasive band surrounding said resilient band, and said openings being adapted to receive a tool for separating said sections as and for the purpose specified.

2. An abrasive Wheel of the character described comprising circumferentially divided sections, each of which include an inwardly inclined rim portion, a disk portion formed in said rim portions, a hub formed with said disk portions, a flange for each rim portion and being formed on its outer edge thereof, a resilient band for said rim portions and disposed between said flanges, said resilient band having its inner face sloped inwardly to be accommodated by the inclined surface of the rim portions, a leather band between the resilient band and rim portions, reinforcing means including a wire mesh embedded within said resilient band, and an abrasive band surrounding said resilient band.

In testimony whereof I aflix my signature.
