BOWLING PIN.

Application ined April s, 1924. serial No. 704,957.

To all whom t may concern:

Be it known that I, JOHN O. MILLER, a citizen of the United States, residing at Chi-- cago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bowling Pins, of which the following is a specification.

This invention relates to improvements in bowling pins, and its object is to provide simple and eliicient means for protecting the base of the pin against wear and thereby maintain the pin in serviceablev condition and prolong its life for a greater period than has been customary herebefore.

Many bowling alleys are provided with pin setting devices which `comprise metal pins operating through the alley bed at the pin spots thereon to project above'the surface of the bed for engaging openings provided for them in the bases of the pins. These metal pins register the bowling pins in correct position on the pin spots on the alley bed, after which they are lowered below the surface of the alley bed, so as not to interfere with the game. The pin boy operates the setter to project the setter pins above the surface' of the alley and then places the bowling pins on the metal setter pins; and after this has been done many times, it is found that the metal pins wear the wood walls of the openings so that correct setting and spotting of the bowling pins is not always assured. This wear of the wall of the mold in the bowling pin makes the pin setting operation more diliicult and laborious because the metal setter pin is somewhat pointed and will not enter a wornv hole properly.

Furthermore, a bowling pin wears in service at the base so that it will' not stand properly, and means are sometimes provided where a number of bowling alleys are installed, as well as at sales rooms for bowling supplies, for re-linishing the bowling pin base; some pins are provided with reinforced bases, and other means have been proposed for reducing the wear on the bases ofthe bowling pins.

My invention has for its object to provide simple means for reducing wear of the setter pins on the bowling pins, and also for reducing the normal wear on the bases of the pins, whereby to prolong the efiicient service of a bowling pin.

merely for the purpose of explaining the invention, and it will be understood that the inventlon can be embodied in any form of bowling pin for which it is or may be adapted.

The drawing is an elevation of a duck p1n and shown partly broken away and in section. The pin 1 shown in the drawing has anannular rubber ring 2 which is now used on duck pins and constitutes no part of my mvention. A plug 3 is inserted in a bore 4t in the bottom of the pin and this plug has a flange 5 which is seated in a counter rbore 6. The plug has a central opening 7 which is of a size and shape adapted to receive the metal registering pin of that form of bowling pin setter which comprises a plurality of metal pins adapted to be projected upward through the alley bed and is known commercially as the simplex pin setter.

The plug is preferably made of liber 1n one piece and secured by glue in the bores, but it can be made of other suitable materials and in more than one piece and securely anchored in the bowling pin in any suitable manner. The plug provides a fiber sleeve 3 which will resist the wear of the setter pin, and the flange 5 provides a bottom or base for the pin which will resist the wear to which the bottom or base of -a bowling pin is subjected. This base 5 preferably projectsslightly below the body the size, shape and arrangement of the plug and that it can be used in other bowling pins and secured in place in any suitable manner, and I reserve the rightl to make all such adaptations of and changes in the construction and arrangement of my. invention as fairly fall within the scope of the following claims.

I claim:

1. A bowling pin having a bore and a counter bore in its base, and a wear preventing tubular plug seated in said bore and having a liange seated in said counter bore.

2. A bowling pin having a bore and a counter bore in its base, a wear preventing tubular plug comprising a sleeve seated in 4. A bowling pin having a, bore and a said bore, and an integral flange seated in counter bore in its base and a wear pre- 10 said counter bore. venting tubular plug comprising a sleeve 3. A bowling pin having a bore and a seated in said bore, and an integral flange 5 counter bore inits base, and a wear preventseated in said counter bore and projecting ing tubular plug seated in sald bore and below the body of the pin. counter bore, andl projecting below the body of the pin. JOHN O. MILLER.
