' Specification of Letters Patent. Patented N OV. 12, 19,18;

y Application led April 18, 1918. Serial No; 229,384.

To all whom t may concern Be it known that I, HARRY R. ALLsHoUs,V

a citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented new and useful Improvements in Reinforced Wooden Articles, f

of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to wooden implements which are subjected to extraordinary shock and wear such as, for instance, bowling pins or the like, its object being to provide a structure for such instruments whereby such portions thereof as may be subjected to such shock may be reinforced so as to retard the destruction of the wood from which the implement is made and thus prolong the life thereof. My said invention consists of means hereinafter fully described and particularly set forth in the claims.

The annexed drawing and the following description set forth in detail certain means embodying my invention the disclosed means constituting but one of the various mechanical forms in which the principles of the invention may be applied.

In said annexed drawing Figure 1 represents a front elevation of a bowling pin constructed in accordance with my invention.

.Figa 2 represents a bottom plan of Such pin.

Fig. 3 represents a fragmentary axial section of the lower or base end of such pin and taken upon the planes indicated by lines IV-IV, in Fig. 2, said figure illustrating the form of the parts in an intermediate stage of the construction of the pin.

Fig. 4 represents a view similar to that shown in Fig. 3 but showing the pin in its completed form.

In applying my invention to a bowling pin as illustrated by the drawing, the lower or base end thereof is first turned so as to form a fiat annular base 1, as shown in Fig. 3. I then drill into the pin a plurality of cylindrical holes 2 the diameter of which is made somewhat greater than the Width of the annulus l. These holes are furthermore drilled so that their aXes converge upwardly and away from the base, such convergence being preferably uniform so as to cause their axes to lie in the surface of a cone.

After these holes are drilled I then 'take a plurality of reinforcing plugs 3 composed of a material having force-resistant qualities greater than those of the wood from which the main body of the pin is made and insert these plugs in such holes securing the same thereln by means of a suitable glue. These plugs are made so as to iit snugly and preferably so as to drive into the holes. Suitable grooves (not shown) may be provided in the sides of the plugs to permit the exit of the air which would otherwise be impounded by such act of insertion, this practice being well known in connection with the insertion of dowel pins as will be readily understood by those skilled in the art.

These plugs may be advantageously made from hard compressed fiber orbhard rubber, but it will be understood that any suitable material for this purpose having the required increased force-resisting qualities may be utilized.

After these plugs have been inserted, as above described, the end of the bowling pin is turned off so as to round the base to assume a convex annular form such as is illustrated in Fig. 4. It will be thus seen that as a result of such turning the sides of the plugs 3 extend laterally both exteriorly and interiorly beyond the lower-most or base plane of the pin, thus presenting their resisting surfaces 1n such lateral direction.

By means of the above described arrangement I obtain a base for the bowling 'pin which is effectively reinforced so as to prevent the destruction of the wood of the base to a large degree which results in a material lengthening of the life of the pin, this base of the pin being, as is well known, that part thereof which is most susceptible to such destruction.

While I have illustrated my invention as applied to a bowling pin and while I have found that it is very advantageously applied to such pins it will be, of course, understood that such reinforcements might be applied to any wooden implement any part of which is subjected to extraordinary force tending to destroy same or shorten the life thereof.

What I claim is:

l. A wooden implement having a base upon which it is adapted to stand and a plurality of cylindrical reinforcing plugs terminating in the surface of said base, the M axes of'si'd base and said plugs being angu larly related to each other.

2. A Wooden implement having a base upon which it is adapted t0 stand and a plurality of cylindrical reinforcing plugs terminating in the surface 0I" said base7 the axes 0f said plugs converging toward each other in a direction away from such base.

face of such base.

Signed by Ine this 13th clay of April, 1918.
