[58] Field Search 30/365 A handle secured to the roller enables the roller to be 30/307, 312, 319; 15/143, 230-11 rolled over a suitable surface to place small indentations therein. [56] References Cited UNITED STATES PATENTS 1 Claim, 6 Drawing Figures 2,471,763 5/1949 Merrick 30/365 PERlF-A-BOARD ROLLER TYPE TOOL FIELD OF THE INVENTION Siding contains hard surface regions on its outer surface constituted by knots and growth marks. Paint does not adhere to these regions nearly as well as it adheres to the remainder of the surface and, subsequently, the paint peels and cracks.

SUMMARY We have discovered that when many closely spaced indentations are formed in these hard surface regions, the paint applied thereto will exhibit more permanent and lasting adhesion. Moreover, when these indentations are formed in surfaces to be repainted, the formation of indentations assists in clearing away loose paint as well' as preparing the surface regions as previously described.

In our invention we provide elongated roller means with an outer cylindrical surface. Many sharp points uniformly spaced over the entire surface extend outward therefrom at right angles thereto. Manually operable means secured to the roller means enables the roller means to be rolled over the outer surface of wood,

siding to produce the desired indentations therein.


FIG. l is a partially cut away side elevation of one form of our invention;

FIG. 2 is one end elevation of the structure of FIG.

FIG. 3 is an opposite end elevation of the structure of FIG. ll;

FIG. 4 is a detail perspective of a modification of the structure of FIG. 1;

FIG. 5 is similar to FIG. 1 but showing another modification thereof; and

FIG. 6 is a detail showing part of the structure of FIG. 5.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring first to FIGS. 1-3, an elongated solid roller 10, cylindrical in shape, has an axial bore 12 with recesses 14 at each end. The outer surface of the roller carries a plurality of closely and uniformly spaced points 16 extending outward from the surface at right angles thereto. Typically the outer surface and points can be of metal and can take the form of a sleeve A slidably engagable with an inner plastic or wood cylinder 10B.

A shank has an elongated section 18 extending through the bore with a free end exposed in one end recess and held in place by nut 20. The other end of the section 18 extends outward from the other end of the roller, is bent at right angles as shown at 22, is bent again at right angles to form an extension 24 parallel to.

section 18 and spaced from the roller and is bent again at right angles to form a final portion 26 engaged by handle 28. A sleeve 30 may be rotatably disposed over extension 24. The invention can then be used as previously described.

The depth of points 16 can decrease linearly with increasing separation from one end of the roller as shown in FIG. 4. This enables the roller to be applied to siding tapering in thickness (such as in simulated shingles) to form indentations of uniform depth despite the differing resistance of the siding, as its thickness varies, to the indentation process.

In FIGS. 5 and 6, the roller 10 is replaced by a plurality of like discs 32. Each disc has a central opening 34 through which section 18 passes and also has an offset hole 40 and an oppositely disposed offset prong 42. The prongs and holes are engaged whereby the discs are locked together side by side and act as a rigid cylinder whereby the same type of roller use as previously described can be obtained.

While the length of the cylinder can vary, I have found that a length of less than 7 inches is satisfactory and that a length of 3 inches is excellent. The points can have the shape of an inverted V, but best results are obtained when the points are rounded with the shape of an old phonograph needle or large sewing needle. If desired, the cylinder can be a solid tube with the points machined into the outer surface.

While we have described our invention with particular reference to the drawings, such is not to be considered as limiting its actual scope.

Having thus described this invention, what is asserted as new is:

1. In combination:

elongated roller means having an outer cylindrical surface and an axial bore;

a plurality of sharp points closely and uniformly distributed over said surface and extending outward therefrom at right angles thereto;

a shank having an elongated section extending through the bore with a free end exposed in one end recess and held in place therein;

the other end of said section extending outward from said bore and back in U-shape again to form a portion parallel to the outside of said roller;

said section being further bent at right angles at the center of the roller for a final portion;

a handle on the end of said final portion to be grasped by one hand; and

a sleeve rotatably disposed over the portion parallel to the roller to be grasped by the other hand. =0
