2 Claims ABSTRACT F THE DISCLOSURE A polishing pad or disk of tufted base fabric with an attached backing of the same diameter and an additional backing disk of smaller diameter, whereby the marginal edge of the polishing pad may be caused to curl in proportion to the amount of pressure applied to such edge.
BACKGROUND OF THE INVENTION Field of the invention The invention is in the eld of bufing and polishing, including pads applied to and rotated by polishing machines for bung and polishing highly polished surfaces of automobiles and other objects for maintaining such surfaces in highly polished condition.
Description of the prior art SUMMARY OF THE INVENTION AND OBJECTS The present invention is a buffing or polishing disk or wheel of relatively simple and inexpensive construction which can be readily produced by using a tufted base fabric with a lightweight fabric backing of corresponding diameter attached to the base fabric, and reinforced by a further backing of heavier fabric of smaller diameter leaving a marginal edge which will be radially curled or curved, the curvature of which is increased by pressure thereon during use.
It is an object of the invention to provide a polishing disk or wheel of relatively simple inexpensive construction having a relatively stiff body with a marginal edge of greater flexibility so that it may curl radially when pressure is applied to such edge in the polishing process.
Other objects and advantages will be apparent from the accompanying description and the accompanying drawing.
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a perspective of the operative surface of a polishing disk or pad;
FIG. 2 a similar view of the rear surface thereof;
FIG. 3 a horizontal section on the line 3 3 of FIG. 2;
FIG. 4 an elevation of the edge of the polishing disk or wheel attached to a machine by which it is driven with a portion of such edge broken away;
FIGS. 5, 6 and 7 are enlarged fragmentary detail sections illustrating the use of the pad for polishing concave surfaces of different curvatures; and
FIG. S is an enlarged fragmentary detailed section.
DESCRIPTION OF THE PREFERRED EMBODIMENT With continued reference to the drawing, the polishing pad of the present invention has a polishing surface 10 of tufted wool in a suitable base 11 of canvas or duck.
The base 11 is of tightly woven heavy canvas with chenille loops of relatively soft thick wool yarn sewn in said base so that the loop portions are in contact with the rear surface of the base and the loops of yarn which extend through the base are cut apart at their extremities to form individual strands on the front side of the base to provide a deep dense soft pile having a relatively smooth operating surface, the individual relatively soft thick wool strands being so closely associated that they laterally support themselves and provide a relatively thick work surface. To this tufted wool base is fastened by means of adhesive, or in any other desired manner, a lightweight fabric backing 12 uniting the same and of the same diameter as the diameter of the basic fabric, and to this is attached by adhesive or by other means an additional backing in the form of a fabric disk 13 of smaller diameter but greater thickness.
These three disks form the essential parts of the complete bufling pad about a central opening 14. The pad thus formed is stiff enough to serve the purpose for which it is intended, nevertheless it is suiciently yieldable to conform to the surface being polished and at the same time due to the thinner fabric along the edge such edge will curl and no stiff fabric edge will be exposed to mar or cause damage to the surface being polished.
In other words, the lightweight fabric 12 reinforces and assists in keeping the stitches in the basic fabric, and the smaller diameter fabric provides the necessary stiffness to the body portion of the pad while the thin edge can curl and thus prevent the rough edge of the canvas or duck from injuring the surface being polished.
In FIG. 4 is disclosed a machine 15 to the spindle 16 of which the polishing pad is connected, and which in turn is connected to a disk or plate 17 which directly engages the pad 13 for rotating the same and performing the polishing action, the pad being attached to the machine in the usual manner.
In FIGS. 5, 6 and 7 are disclosed curved surfaces 18, 19 and 20 of different curvatures and illustrating how the brush can conform to the contour of such surfaces.
What is claimed is:
1. A disk type polishing pad comprising a tightly woven relatively heavy canvas base, chenille loops of relatively soft thick yarn sewn in said base so that the loop portions are in contact with the rear surface of said base and the loops of yarn which extend through said base are cut apart at their extremities to form individual strands on the front side of said base to provide a deep dense soft pile with a relatively smooth operating surface, the individual relatively soft thick strands being so closely associated that they laterally support themselves and provide a relatively thick work surface, a lightweight exible fabric attached over the loops on the rear surface of said base and uniting the same, and a canvas backing overlying said lightweight fabric but being of smaller diameter so that the marginal edge of said pad can curl when pressure is applied to such marginal edge due to its relative thinness and the amount of curl will be in proportion to the amount of pressure applied.
2. A polishing pad including a tufted base fabric disk to provide a deep dense soft pile with a relatively smooth operating surface a lightweight relatively thin fabric disk corresponding in diameter and attached to the back of and reinforcing said tufted base fabric disk while allowing exing and the accommodation of the polishing pad to a surface being polished, a relatively thick fabric back- 3 4 therewith, and when pressure is applied to the marginal 3,084,364 4/ 1963 Hutchins 15-97 edge prton of the pad causing it to curl, said edge por` 3,413,674 12/ 1968 Reid 15-230.12
tion will remain of constant thickness regardless of the amount of pressure applied.` FOREIGN lPATENTS 355,999 9/ 1931 lGreat Britain.
