BOWLING PIN.

This invention relates to bowling pins and it is especially useful in those pins which are made of a plastic composition in the form of a hollow shell.

It has been found in practice that bowling pins made of plastic composition in the form of a hollow shell are liable to break at the neck because of the bending strains to which the neck is subjected under the impact of the ball against the body of the pin and also from the blows to which the body and the head are subjected in the bowling alley pit.

The object of my invention is to reinforce and strengthen the neck of the pin so that it will satisfactorily resist the bending strains to which the neck of the pin is subjected in actual use, and to do this in a manner and by use of means which will not add materially to the cost of manufacture.

In the accompanying drawings have illustrated the invention in a pin made of plastic composition in a simple form, and referring thereto- Fig. 1 is a vertical central sectional view.

Fig. 2 is a transverse sectional view on the line 22 of Fig. 1., and

Fig. 3 is a detail perspective view of one of the reinforcing members.

Referring to the drawings, the pin comprises a shell made of a plastic composition, such as a hard rubber compound, and having a body 4-,, a neck 5 and a head 6. I have shown this shell in a simple form to illustrate the adaptation of my invention, but it will be understood that the invention can be employed in any form of hollow composition shell to which it is or may be adapted. A plurality of reinforcing strips or members 7 are embedded in the neck of the shell on the inner surface thereof and preferably extend throughout the length of the neck and. into the body and head of the pin. I prefer to make these members or strips of resilient strengthening and reinforcing material, and for this purpose I have found spring metal satisfactory because it can be made thin, light in weight and easily applied. The members may be secured to the shell in a suitable manner as by providing the members with projections or barbs. 8 and turning over the-ends 9 so that all of 16, 1925. Serial N0. 9,371.

the projections will be embedded in the neck of the shell as shown in Fig. i.

These members or strips reinforce and strengthen the neck of the pin to resist the strains to which the neck is subjected in the use of the pins. As many of the members may be provided as found to be necessary or desirable and they can be made narrower or wider than those shown in the drawings, as good practice may require. However, i have found that four members of substantially the size and shape illustrated answer the purpose satisfactorily. Not only do these members resist the strains to which the neck of the pin is subjected in use, but they strengthen and reinforce the neck of the pin generally and in that Way prolong the life of the pin.

I am aware that changes may be made in the construction and arrangement of my invention, some of which have been hereinbefore indicated, andI reserve the right to make all such changes as fairly fall within the scope of the following claims:

I claim:

1. A bowling pin comprising a shell made of plastic composition and having spaced reinforcing members embedded in the neck lengthwise thereof.

2. A bowling pin comprising a shell made of plastic composition and having a plurality of relatively narrow elongated strengthening and reinforcing members spaced apart and embedded in the neck thereof.

3. A bowling pin comprising a shell made of plastic composition and having a plurality of relatively narrow and resilient metal members embedded in the inner surf-ace, of the neck thereof to strengthen and reinforce the neck.

4. A bowling pin comprising a shell made of plastic composition, and a, plurality of strengthening and reinforcing members having projections thereon embedded in the inner surface of the neck thereof.

5. A bowling pin comprising a shell made of plastic composition, and a plurality of strengthening and reinforcing metal members extending throughout the neck thereof and beyond to the body and to the head of the pin and having projections embedded in the inner surface of the neck.
