THE GOODRICH TENNIS BALL. 



THE growing interest in lawn tennis in the United States 

 has induced The B. F. Goodrich Co. (Alcron, Ohio), 

 whose success in the manufacture of golf balls has 

 become so pronounced, to engage in making tennis 

 balls on an e.xtensive scale, in which every part is a product of 



their factory, whereas the tennis 

 balls used here hitherto have had 

 imported rubber centers. There 

 are some peculiarities in the mak- 

 ing of the " Goodrich " tennis 

 ball, that the company refer to as 

 giving them a marked advantage. 

 In the first place, they use three 

 thicknesses of rubber in the " cen- 

 ter " shell, instead of two thick- 

 nesses as has been customary 

 heretofore, and the advantage is explained by the statement 

 that calendered rubber stretches across the grain, rendering 

 the balls likely to lose their exact roundness when inflated. 

 In making the Goodrich ball two plies of the rubber are 

 joined, with the grains at right angles, which eflfectually 

 keeps the ball in shape. A third layer of an air tight 

 solution of thin rubber is put inside the shell as a lining, 

 to make it better hold compressed air, while the seams 

 where the ball is put together are covered with extra " patches" 

 to make them air tight. Another point of advantage 

 claimed is in the sewing, which is the most important fea- 

 ture in the lasting quality of a lawn tennis ball. A ball in 

 which a single stitch shows on the surface of the felt is likely 

 to rip soon, through the thread at this point becoming cut, af- 

 ter which the cover soon becomes loose. " Goodrich " balls 

 are " under sewn " entirely ; that is, the stitches are taken from 

 the side or edge of the felt, instead of the top, so that they do 

 not come to the surface to be cut or ripped, and yet they hold 

 the cover more firmly than those which do. These balls are 

 tested for size, for weight, for firmness, for roundness, and for 

 the stitching of the cover, and packed in tissue paper, three to 

 a box, and sold under a guarantee, at what is stated to be not 

 more than the price of other high class makes. 



DAVOL's whirlpool spray syringe — NO. 2 12. 



The first of the cuts shown herewith relates to a vaginal 

 douche spray which has been designed with a view to combin- 

 ing in one article the best features of the old style 

 popular syringes with the modern whirlpool rotary 

 spray principle, contributing to effectiveness and 

 simplicity, and the ease in use and the comfort 

 ^ of the user. This syringe throws 



a rotating hoUaw mass of water, with 

 the efltect of thoroughly cleansing 

 without the liability of harmful ef- 

 fects. It is constructed wholly of 

 hard and soft rubber, having no 

 valves to lose and no metals to cor- 

 rode. The rubber shield fits per- 

 fectly, and prevents all chance of leakage. The second cut 

 relates to the household " Handy Line "of rotary spray syringes, 

 capable of easy use with one hand. All the pipes are of hard 

 rubber, and adapted to the rotary spray. [Davol Rubber Co.

THREE HOSE NOVELTIES. 

 The " Hartford " rack, illustrated in the first of the three ac- 

 companying cuts, is a variation of the "Dewey" hose rack 



[See The India Rub- 

 HER World, May 1,1899 

 — page 216], for interior 

 fire hose equipment. In 

 the new type, an arched 

 instead of the straight 

 bed plate is used, the 

 result being that when 

 HARTFORD. ^j,g jjQgg jg coiled in the 



rack, the top of the pile is horizontal, and not concave. This 



rack is made in the same sizes as the " Dewey." It is made 



with wall brackets, and with pipe clamps. The racks are 



Japanned red, with parts most 



liable to be broken in malleable 



iron.^^^ The Gibbs garden spray 



nozzle, shown in the second of ^ 



the cuts, represents the result of gjS^ 



many years' experimenting. The 



shut-ofl is positive, because it is 



made by a washer against a ' 



shoulder at the base of the pipe. It gives a fine spray, and, it 



is claimed, a greater variation of sprays than any other nozzle. 



The straight stream, of course, is the same as with any other 



hose pipe. The nozzle is made of 

 few parts, its simplicity of con- 

 struction rendering it not likely 

 to get out of order.^=Sykes's 

 hose holder, shown in the third 

 cut, is a simple but very efTective 

 little article that sticks in the 

 ground on the lawn to hold the 

 hose, with a view to directing the 

 spray when used in connection 

 with a garden hose nozzle. This 

 article is intended to retail at 25 

 ' cents, which price is referred to 

 as allowing a good profit to the

A NEW ladies' rubber HEEL. 



Rubber heels hitherto have been made for the most part in 

 broad styles, which fact probably has led many ladies to re- 

 frain from wearing these 

 heels. The manufactur- 

 ers of the heel widely 

 known as the " Velvet " 

 have recently introduc- 

 ed on the market a heel 

 of the French or mili- 

 tary shape, as shown in 

 the illustration, which is 

 particularly neat in form 

 and which is offered in color similar to leather heels, being 

 " always black." This new heel is made in graduated sizes, to 

 fit any call for a heel of this character. It is covered by the 

 regular " Velvet " trademark, which the trade is warned not to 

 infringe. [Frank W. Whitcher & Co., Boston and Chicago.]
