G. L. PIERCE. SHOT FOR ATHLETIC USES.
APPLICATION FILED APR.13. I905.

Specification of Letters Patent.
Patented Dec. 19, 1905.
Application filed April 13, 1905. Serial No. 255,373.
To all whom it may concern.-
Be it known that I, GEORGE L. PIERCE, a citizen of the United States, residing in the borough of Brooklyn, in the county of Kings, in the city and State of New York, have invented certain new and useful Improvements in Shots for Athletic Uses, of which the following is a specification.
This invention relates to what is called a shot to be thrown or put by an athlete. This is sometimes an iron ball, like a cannonball, either with or Without a cover of leather, and sometimes a bag of leaden shot covered with leather.
The present invention relates especially to the last-named form or species, wherein leaden shot supply the weight and bulk and provide a dead shot.
The object of the present invention is to improve the cover or casing which incloses the shot, as will be hereinafter explained.
In the accompanying drawing, which illustrates an embodiment of the invention, the figure is a side elevation of the ball or shot, partly broken away at the right in the figure in order to disclose the construction.
In the said drawing, 1 designates the leaden shot which provide the weight for the sphere or shot. These are inclosed in a spherical bag 2 of some woven fabric, as thin canvas or the like. This spherical bag of leaden shot is then inclosed in an outer casing formed as will be explained.
Wrapped about the fabric 2 as a reinforce are strips of fabric 3, consisting of a woven fabric charged or saturated with vulcanizable rubber or rubber mixed with sulfur in proper proportion to vulcanize into an elastic vulcanized rubber by the proper application of heat. There may be and usually will be several plies or thickness of this reinforcing fabric 3.
After the fabric 3 shall have been applied and pressed firmly over the fabric 2 there is applied an outer covering 4 of vulcanizable rubber, and the covered shot is then put into the vulcanizing-chamber and the rubber vulcanized. The result will be a shot S having an integral or seamless rubber cover, the outer cover t being made practically integral by vulcanization with the reinforcing fabric 3. The rubber in the fabric 3 will also be made to adhere firmly to the material forming the bag 2.
The rubber used need not be pure, as many vulcanized-rubber articles contain some adulterant. The invention is also applicable to a shot for this use where the material used for imparting weight is not leaden shot.
Preferably the fabrics 2 and 3 will be woven fabrics and they have been described as such; but obviously any strong flexible material may be employed which will withstand the process of vulcanizing the rubber.
Having thus described my invention, I claim- 1. A shot for athletic uses, having leaden shot in its interior to provide weight, a bag of woven fabric inclosing said leaden shot in spherical form,and a seamless,vulcanized-rub ber covering for said bag, said rubber covering having an internal reinforce of woven fabric.
2. A shot for athletic uses, consisting of a loose mass of leaden shot 1, of substantially spherical form, a bag 2, of woven fabric inclosing said leaden shot, a reinforce 3 of strips of woven fabric containing rubber, and an outer covering 4 of rubber, the rubber 0f the covering 4 being united integrally with the rubber of the reinforce 3 by vulcanization.
In witness whereof I have hereunto signed my name, this 12th day of April, 1905, in the presence of two subscribing witnesses.
GEORGE L. PIERCE.
