Claims.

The present invention relates to improvements inbuiilng wheels, and particularly to improvements in buffing wheel sections where a plurality of the sections are adapted to be assembled and secured together on a rotating spindle to provide a completed bufling wheel.

One of the primary objects of this invention is to provide an improved bufling wheel section which is simple in its construction, and which is economical to manufacture.

A further object of the invention is to provide a buifing wheel section in which the hub and spokes are formed of wire elements and secured to the buffing wheel mounting ring in such a. way as to provide an economical construction.

Other objects of the invention will become apparent from the following specification, the drawing relating thereto, and from the claims hereinafter set forth.

In the drawing in which like numerals are used to designate like parts in the several views throughout:

Figure 1 is a side elevatlonal view of a bufling wheel section embodying features of the present invention;

Fig. 2 is an enlarged, fragmentary cross-sectional view, taken substantially along the line 2-2 of Fig. 1;

Fig. 3 is an enlarged, fragmentary cross-sectional view, taken substantially along the line 3-3 of Fig. 1;

Fig. 4 is a perspective View of one of the wire hub and spoke elements forming a part of the present invention; and

Fig. 5 is a perspective View of a center closure plate employed with the bufing section of the present invention.

Referring to the drawing, the buffing wheel section comprises a wire ring I upon which an annular buifing section 2 is mounted. The bufiing section 2 is formed of a strip of cloth fabric which has a width substantially twice the radial depth of the bufiing section when it is in its final position on the ring I. In forming the bufiing section 2, the strip is wound upon itself in a suitable number of layers and generally in a cylindrical form. The ring I is then placed over the cylindrically wrapped layers of fabric at substantially the transverse midpoint thereof and those portions of the fabric on opposite sides of the ring are then folded radially outwardly of the ring. The inner part of the bufilng wheel section, indicated at 3, is evenly gathered about the ring and stitched thereto around the outside, as indicated at 4.

A pair of wire elements 5 are secured to the buffing section 2 and to the ring I and are of such construction and arrangement as to provide the mounting hub for the section as well as the wire spokes. Each element 5 is generally V- shaped in form having the bite thereof rounded, as indicated at t, and having the outer ends thereof reversely bent and pointed to provide hooks, indicated at I. A pair of elements 5 are disposed in diametrically opposed positions with respect to the inside of the ring I so that the rounded ends 5 overlap to provide a hub and axial opening within which the driving shaft is received. The arms of the elements 5 are at such an angle with respect to each other that the outer hooked ends engage around the periphery of the ring I at substantially uniform spacing around the ring. The arms thus form the spokes for the bufiing wheel segment.

The hooked ends I of the elements 5 are pierced through the buffing wheel section 2 outwardly of the ring I and are then clamped around the ring I. One of the elements 5 is disposed on one side of the section with the hooked ends passing over the ring I in one direction, and the other element 5 is disposed on the other side of the section with its hooked ends I disposed in the opposite direction around the ring I. The engagement of the hooked ends through the buffing wheel section 2 serves to hold the elements 5 against displacement around the ring I.

While not necessary under the broad aspects of the present invention, it may be desirable to close the space within ring I. For this purpose, a disk 9 having a central opening I0 is disposed within the ring I, with the periphery thereof abutting against the inside annular edge of the buffing element 2. The disk 9 is disposed between the inside adjacent edges of elements 5, and the hooked ends I are clamped against the disk 9, as shown in Fig. 2, so that the disk is firmly held in position. In the embodiment illustrated, the disk 9 is formed of laminated sheets of cardboard, but it may be of other material.

In the use of the buffing wheel section of the present invention, a plurality of such sections are mounted on a suitable spindle, enough of such sections being employed to build up a wheel of the desired width. End plates may then be used to clamp the sections together on the spindle so that such sections will rotate with the spindle.

Formal changes may be made in the specific embodiment of the invention described without departing from the substance thereof, the scope of which is commensurate with the appended claims.

What is claimed is:

1. A bufiing wheel section comprising an annular bufiing section of fabric, an annular metal ring, said bufiing section bein mounted on said ring, and V-shaped wire members having their outer ends secured to said ring at annularly spaced points and having their inner ends overlapped to provide a shaft-receiving hub.

2. A bufiing wheel section comprising an annular buffing section of fabric, an annular metal ring, said bufiing section being mounted on'said ring, and a plurality of V-shaped wire members having their outer ends hooked through said buffing section and around said ring at annularly spaced points and having their inner ends overlapped to provide a shaft-receiving hub.

3. A buffing wheel section comprising an annular bufling section of fabric, an annular metal ringusaid bufling section being folded around the inside of said ring and extending radially therebeyond, and a plurality of V-shaped wire members having their outer ends hooked through said bufiing section outwardly of said ring and hooked around said ring at-annularly spaced points said a shaft-receiving hub.

5. A buffing wheel section comprising an annular bufiin section of fabric, an annular metal ring, said buffing section being mounted on said ring, a pair of V-shaped wire members extending from the center of said ring in diametrically opposed positions to provide wire spokes, the

outer ends of said wire members being hooked through said buifing section and around said ring at annuiarly spaced points, the bights of said wire members being rounded and overlapped'to provide a shaft-receiving hub.
