GOLF-BALL.

SPECIFICATION forming part of Letters Patent No. 710,750, dated October 7, 1902.

Application filed July 30, 1902, Serial No. 117,604 (No model.)

To all whom, it may concern: 7'

Be it known that I, RICHARD B. CAVANAGH, a citizen of the United States, residing in \Vashington, in the District of Cl umbia,have

invented certain new and useful Improvements in Golf-Balls, of which the following is a specification. p

This invention relates to golfballs and its object is to reduce the cost and improve the 0 durability and other qualities of the balls.

Some of the golf-balls now in use are so lively that they meet with disfavor with many players, since it is impossible to make accurate puts and approaches.

My improved ball combines the feature of exceedingly low price and durability and avoids the disadvantage of being too lively for a short game, while well adapted for a long flight when given a heavy blow.

The accompanying drawing shows one form of golf-ball made in accordance with my improvements.

For a center piece A, I employ hard rigid material, preferably hard wood, although asbcstos or asphalt or other suitable substance may be employed. This center piece I inclose in asphere B of moderate size and consisting of sawdust, ground cork, or other comminuted material mixed with a compound of glue or glycerin or any other suitable viscous or colloid mixture. This sphere is preferably formed under great pressure, so that the comminuted material is compressed and the whole sphere is highly compacted. If desired, the

sphere B may be compressed into the form of half-shells and then applied to the center pieceAand subjected to further compression.

The comminuted material is indicated at B and the cement at B.

The sphere B, I inclose in a relatively thin spherical layer C of highly-compressed paperpulp similar to that employed in the manufacture of car-wheels or lincrusta-ware. This material is very durable and springy and contributes to the flight of a ball.

Upon the layer C, I apply a shell D, composed of a mixture similar or analogous to that employed for the shell I and the whole is inclosed in a cover E of gutta-percha, which preferably holds the filling of the ball in a state of compression.

It will be seen that the spheres B and D taken together form a thick layer or sphere, which is provided with a lining or inlaid layer 0 of relatively stiff hard material, whereby undue disturbance of either layer B or D under a blow is prevented, and hence undue distortion of the filling and cover is avoided. The comminuted material and the glue compound 1 are sufficiently springy to enable the ball to make a long flight undera heavy blow, while the ball is comparatively dead under a light blow, thereby meeting the requirements of the game.

Variations may be resorted to within the scope of my improvements. I

Having described my invention, I claim-- 1. A golf-ball comprising spheres of comminuted material, mixed with an adherent substance, an imperforate layer of hard ma- 7o terial separating said spheres, and a hard cover.

2. A golf-ball comprising spheres of compressed comminuted material, mixed with an adherent substance, an imperforate layer of compressed hard springy material separating said spheres, and a cover of gutta-percha.

3. A golf-ball comprising spheres of comminuted material mixed with adherent material, an imperforate layer of hard springy 8o material separating said spheres, and a hard cover.

4. A golf-ball comprising spheres of comminuted material mixed with a compound of glue and glycerin, an imperforate layer of hard material separating said spheres, and a hard cover.

5. A golf-ball comprising spheres of comminuted compressed cork, an imperforate layer of hard, springy material separating go said spheres, and a cover of gutta-percha.

6. A golf-ball comprising a hard center piece, a layer thereon of comminuted material, a layer of paper upon said comminuted material, a layer of comminuted material 5 upon said paper, and a cover of plastic material.

7. A golf-ball comprising a hard center piece, a layer of comminuted material mixed with adherent material, a layer of paper upon said commiuuted material mixed with adherent material, a layer of comminuted material upon said paper, and a cover of plastic ma terial.

S. A golf-ball comprising a hard center piece, a layer thereon of compressed comminuted material mixed with glue, a layer of paper upon said comminuted material, a layer upon said paper consisting of comminuted material mixed with glue, and a guttapercha cover.

9. A golfball comprising a hard center piece, a layer thereon of compressed comminuted material mixed With a compound of glue and glycerin, a layer of paper upon said comminuted material, a layer upon said paper consisting of comminuted material mixed with a compound of glue and glycerin, and a gutta-percha cover.

10. A playing ball comprising a relatively thin layer of compressed paper and two relatively thick spheres of softer springy material separated by said paper layer.

11. A playing-ball comprising an imperforate layer of compressed paper and two spheres of softer springy material separated by said paper layer.

12. A golf-ball comprising a sphere of compressed comminuted cork mixed with a compound of glue and glycerin, and a covering of compressed gutta percha holding said sphere under compression.

13. A golf-ball comprising a plurality of spheres of comminuted material, a layer of hard material separating said spheres, and a cover of compressed plastic material holding said spheres under compression.

14. A golf-ball comprising a plurality of spheres of compressed comminuted material,

a layer of compressed hard springy material separating said spheres, and a cover of compressed gutta-percha holding said spheres under compression. 7

15. A golf-ball comprising a plurality of spheres of comminuted material mixed with adherent material, a layer of hard material separating said spheres, and a cover of plastic material holding said spheres under compression.

16. A golf-ball comprising a hard center piece, a layer thereon of compressed comminuted material, a layer of compressed paper upon said comminuted material, a layer of compressed comminuted material upon said paper, and a cover of compressed plastic material holding said comminuted material under compression.

17. A golf-ball comprising a hard center piece, a layer thereon of compressed comminuted material mixed with glue, a layer of compressed paper upon said comminuted material, a layer upon said paper consisting of compressed comminuted material mixed with glue, and a gutta-percha cover holding said layers under compression.

18. A golf-ball comprising a hard center piece, a layer thereon of compressed comminuted material mixed with a compound of glue and glycerin, a layer of compressed paper upon said comminuted material, a layer upon said paper consisting of compressed comminuted material mixed with a compound of glue and glycerin, and a compressed gu ttapercha cover holding said layers under compression.
