This invention relates to-abrasive polishing wheels.
An object of this invention is to provide an abrasive polishing wheel which is polygonal in front elevation and is so designed that the abrasive action is produced by the corners of the wheel, and as the corners wear down successive new corners are brought into operation.
Another object of this invention is to provide an abrasive wheel which is formed of right angularly disposed interlaced or interlocked abrasive strips which may be held together by means of adhesive or other securing means.
A further object of this invention is to provide an abrasive wheel which is formed of laminated layers of abrasive material which are interlaced together so as to provide progressively usable abrasive surfaces as the outer surfaces wear down.
With the above and other objects in view, my invention consists in the arrangement, combina- 4 ca s. (or. 51-193) tion and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.
In the drawings:
Figure l is a detailed front elevation of an abrasive polishing pad or element constructed according to an embodiment of this invention.
Figure 2 is an end elevation of this device.
Figure 3 is a sectional view taken on the line 3-3 of Figure 1.
Figure 4 is a plan view partly broken away showing the manner in which the abrasive strips are initially secured together and interlaced.
Figure 5 is a view similar to Figure 4 showing the abrasive faces of the strips.
Figure 6 is a front elevation showing a modified form of this invention.
Figure 7 is a fragmentary sectional view taken on the line 11 of Figure 6.
Figure 8 is a fragmentary front elevation of another modification of this invention.
Referring to the drawings, and, first, to Figures 1 to 5, inclusive, the numerals l0 and H designate generally a pair of elongated abrasive strips having a fabric base. The abrasive strips 10 and II are initially secured together in overlapping relation and at right angles to each other as shown in Figures 4 and 5 with the abrasive faces of the strips on the same sides. The strips Ill and II are then alternately overlapped one upon the other so as to interlace the strips and in the final overlapping of the strips, the end of the strip [0 will terminate as shown in Figures 2 and 3 at a point inwardly from the marginal edges of the pad formed thereby. The pad generally designated as [2 which is formed by the interlacing of the stripslll and I l together will beoi substantially polygonal. form as shown inFigure 3 with cutouts I3 at each corner.
In the interlacing of the strips together, the marginal or outer edges of the pad formed by the overlapping and interlacing of the strips will form a convex transversely curved marginal edge i4. Where the pad is of relatively large size, a core or sleeve I5 is extended centrally through aligned openings is which are formed in the overlapping portions of the strips, and a mandrel I1 is extended through the sleeve or core l5.
In the construction shown in Figures 1 to 5, inclusive, the terminal end portion of the abrasive strip It] may be secured to the adjacent portion of the strip H by adhesive l8 or the like. If desired, the several folds or overlapping portions of the abrasive strips may be securely fastened together by adhesive so that the central body portion of the pad will be relatively solid; whereas the outer marginal portions of the pad will be of cushioned characteristic.
Referring now to Figure 6, there is disclosed a modification of this invention wherein abrasive strips Illa and Ila are interlaced together after the manner shown in Figures 1 to 5, inclusive. The pad Ila shown in Figure 6 is relatively thinner than the pad shown in Figure 3, and in this instance a piece of adhesive tape I9 is wrapped about the terminal end of the abrasive strip Illa and engages about the overlapping or laminated portions of the strips Illa and Ila. Preferably the adhesive securing member I9 is disposed inwardly from one marginal edge of the pad so that the adhesive tape or strip will not be torn during the use of the pad.
Referring now to Figure, 8 there is disclosed another modification of this invention wherein the abrasive strips lllb and lib are disposed in overlapping and interlaced position. In the present instance, however, the strips lllb and I lb have a folded length substantially greater than the width of the strips so as to thereby form a pad of substantially cross shape. Figure 8 will provide a pad which has slightly greater cushion characteristics than the pads shown in Figures 1 to 6, inclusive.
In the use and operation of this abrasive pad, the mandrel I1 is extended through the center of the pad and secured thereto by means of a nut 20. The pad is then rotated with the corners of the pad engaging the work, and as the corners of the pad wear down, the outermost turns of each strip will wear off and the succeeding turns or folds of the strip will be rendered efiective.
The pad shown in sheet material folded upon itself toform a plu-,
rality of plies,"adhesive'means'binding said plies together into a flat pad having angular corners V pad.
3. An abrasive pad comprising mjsm g of 15 abrasive coated sheet material arranged at right angles to each other and folded in plies upon Number abrasive coated sheet material arranged at right angles to each other and folded in plies upon each other to form an X-shaped flat pad with radially extending arms, the plies of said pad being adhesively vbonded together and said pad having an aperture through the center thereof, and a bushing disposed in said aperture.
