Original application December 29, 1949, Serial No. 135,675, now Patent No. 2,693,064, dated November 2, 1954. Divided and this application April 2, 1954, Serial No. 420,510
8 Claims. (Cl. 51193) This invention relates to an improved manner of construction of a surface-treating wheel by which it is easily and simply provided with a uniform distribution of surface-treating material.
This application. is a division of my copending application entitled Method of Making a Buifing Wheel, filed December 29, 1949, U. S. Serial No. 135,675, now Patent No. 2,693,064 issued November 2, 1954.
According to this invention a pluarlity of strips of surface-treating material are disposed at an acute angle across a cable and are then folded over the cable so that the opposite ends of each strip are divergently related, i. e. the ends of each strip are divergent at opposite angles to a plane transverse to the cable, preferably with such opposite ends extending along lines bisected by a plane transverse to the cable. Thus the ends of each strip are offset in a direction parallel to the cable.
The opposite ends of each strip may then most preferably be sewed together close to the cable and then the cable may be wound on a suitable core so that the strips of surface-treating material project outwardly from the core and the opposite ends of each strip will be circumferentially displaced.
' With this arrangement, the total circumferential extent of each strip will be greater than the extent of the strip at the cable while the angle subtended by the portions of each strip at the periphery of the wheel may be approximately equal to the angle subtended by the portion of the strip at the cable. Accordingly, it is not necessary to bunch, gather or pleat the strips close to the cable and yet a very uniform distribution of the surface-treating material at the periphery of the wheel may be achieved.
An object of this invention, accordingly, is to provide an improved surface-treating assembly in which a cable is wound on a core and a plurality of strips of surfacetreating material are folded over the cable to project outwardly from the core with the opposite ends of each strip being divergently related and circumferentially displaced.
Another object of this invention is to provide an improved surface-treating assembly in which a plurality of strips of surface-treating material are folded over a cable with the cable crossing each strip at an acute angle.
A further object of this invention is to provide an improved surface-treating assembly in which strips of surface-treating material are folded over a cable with the opposite ends of each strip divergently related and with such opposite ends sewed together close to the cable.
Still another object of this invention is to provide an improved method of making a surface-treating assembly.
This invention contemplates other objects, features and advantages which will become more fully apparent from the following detailed description taken in conjunction with the accompanying drawings which illustrates a preferred embodiment and in which:
Figure 1 is a fragmentary and elevational view of a portion of a surface-treating wheel constructed according to the principles of this invention;
Figure 2 is a side elevational view, on a reduced scale, of the wheel of Figure 1;
Figure 3 is an end elevational view of one of the. strips of surface-treating material in folded condition, as utilized in the wheel of Figures 1 and 2;
Figure 4 is a plan view of one of the strips of surfacetreating material, before folding;
Figure 5 is a cross-sectional View of the strip of Figure 4 taken substantially along line VV of that figure; and
Figure 6 is a perspective view illustrating one manner of this position of the strips of surface-treating material on a cable prior to winding of the cable on a core.
Reference numeral. 10 generally designates a surfacetreating wheel constructed according to the principles of this invention. The wheel 10 may comprise a cable 11 wound on a core 12 with a plurality of strips 14 of surface treating material folded over the cable 11 to project outwardly from the core. The core 12 may have an irregular peripheral surface corresponding to the contour of an article to be surface-treated with the radial extent of the strips 14 being uniform and with the core 12 being grooved to receive the cable, as more fully described in my abovereferred to copending application of which this application is a division- According to this invention, each of the strips 14 has opposite end portions 15 and 16 divergently related so that the terminal ends thereof are offset in a direction parallel to the cable 11. Hence, the portions 15 and 16 extend at opposite angles, preferably equal, relative to a plane through the axis of the core 12 and through a mid point of the strip 14 at the cable 11. Such a plane, accordingly, bisects the angle defined by the medial lines of the opposite end portions 15 and 16.
With this arrangement, the circumferential extent of each strip 14 at the terminal ends of the portions 15 and 16 thereof is greater than the extent of the strip 14 at the cable 11. Most preferably, the angle of divergence of the portions 15 and 16 may be such that the angle subtended by the terminal ends of the portions 15 and 16 is equal to the angle subtended by the portion of the strip 14 at the cable 11. With this relation, the leading edge of one of the portions, for example, the edge 17 of the portion 15, and the trailing edge of the opposite portion, for example, the edge 18 of the portion 16 will both extend along a radius of the wheel 10.
With the arrangement as thus far described, it is possible to achieve a uniform distribution of surface-treating material at the peripheral boundary of the wheel 10 but bunching, gathering or pleating of the material at the cable 11 is not required.
The strips 14 may be constructed in any desired manner and of any desired material. Preferably, however, each strip may be made up of a sheet of buffing material folded over on itself several times and then joined together by stitching 19 as illustrated in Figures 4 and 5.
In assembly, the cable 11 may be disposed at an acute angle across the central portion of each of the strips 14 as illustrated in Figure 4 and the opposite end portions 15 and 16 of the strip 14 may then be folded about the cable 11 to positions as illustrated in Figures 3 and 6. Most preferably, the opposite end portions 15 and 16 are then stitched together close to the cable 11 by stitching 20. This insures that the portions 15 and 16 will be at proper divergent angles when the cable 11 is subsequently wound on the core 12.
Instead of placing the strips 14 on the cable 11 and then subsequently winding the cable on the core 12, the strips 14 could be folded about the cable 11 as the cable is wound on the core 12. With such an arrangement, however, it is more difiicult to obtain the proper angular dis position of the opposite end portions of the strips and the method in which the strips are placed about the cable and then stitched close to the cable and the cable subsequently wound on the core is preferred.
It will be understood that modifications and variations may be effected without departing from the spirit and scope of the novel concepts of the present invention.
