KEMPSHALLS NEWEST GOLF BALL. 



Tl i IC amazing- aclivit\" of Mr. Eleazer Konipshall as ,1 golf 

 ball inventor has been referred to already in these pages. 

 It is much to his credit that he has been able to find the 

 money to pay for the great number of fees which have been 

 necessary to meet the requirements for the Kempshall patents 

 at Washington and London, not to mention the other great 

 capitals of the earth. Not so long ago we described in these 

 pages the "Flat Bramble" golf ball. Now is to be mentioned a

new type of the Kempshall output. Although the inside of the 

 new ball is similar to others of the same make, the outside is 

 marked by a series of wavy bands, separated not by the usual 

 little round knobs, or "'bramble," ])ut by circular recesses in which 

 are minute "protuberances." This design is covered by the 

 United States patent No. 922,773. [The Kempshall Rubber Manu- 

 facturing Co., Arlington, New Jersey.] 



THE BHICTSON TIRE TREAD. 



The construction of this new tire tread involves an outer 

 layer of specially tanned and very pliable chrome leather. Next 

 to the outer chrome leather are five plies of cotton tire fabric. 

 Inside of these is another layer of leather. Through the outer 

 leather and the five plies of cotton are driven the steel stud and 

 steel rivet clinched into the layer of leather which follows the 

 lire fal)ric and then there is another layer of leather which

covers these clinched ends of rivets and studs and prevents them 

 from coming into contact with the rubber til e. The ends of 

 the outer layer of chrome leather are skived or sliced thin where 

 they are placed between the rubber tire and rim. This does 

 away with any possibility of thick ends which might crumple up, 

 and makes possible a snug fit of the Brictson tread over the 

 rubber tire. [The Brictson Manufacturing Co., Inc., Brookings, 

 South Dakota.] 



BILATERAL HOSE. 



The "bi-lateral" type of hose now being marketed is claimed 

 to be more durable than the ordinary pattern, as the new con- 

 struction obviates the tendency to crack at the two places where 

 the jacket bends, which disposition is caused by compression. 

 The compression of the lining is occasioned by changing from 

 the arc of a circle that measures zyi" across to one about the 

 size of an ordinary lead pencil, and which causes the rubber to 

 lose its moisture and dry out much quicker at the circle point 

 than in other parts of the lining. The compression also causes 



Ihe two to crease which eventually results in a crack. The bi- 

 l.iteral improvement leaves the rubber free at the two points 

 where the bend takes place in the jacket. When the hose flattens 

 the rubber gets from "in under," and as it is not attached to the 

 jacket, it takes three distinct curves, which relieves it from all 

 compression and crease. The niothod of stretching back ruhlicr

that was condensed at two places so that the tube will be suffi- 

 ciently large for the jacket consists in merely straightening out 

 the three cruves. There is no stretching or elasticity demanded 

 at these two points because there is no loss or compression when 

 ihe hose is fiattened. [The I'i-I-ateral Fire Hose Co., Chicago.] 



■GOOD SAMARITAN' HOT WATER BOTTLE. 



Tins popular type of hot water bottle, made under the process 

 of Mr. Frederick J. Gleason, is molded from one piece of rubber 

 without seams or joints or cement and without the use of wire 

 in its construction. Its hollow disk shape and thin model make it

 pillowlikc and comfortable to lie upon. It is referred to as the 

 only hot water bottle which fits every part of the body. The ten 

 inch two quarts size retails for $2.50. [Walpole Rubber Co., No. 

 185 Summer street, Boston.] 



NOVELTIES BRIEFLY MENTIONED. 



A NEW line of footwear specialties in which sponge rubber is 

 the active principle includes a hygienic cushion arch support made 

 with a Russia calf top, a rubber sponge center, and ooze calf 

 bottom. The company making these is turning out a somewhat 

 unique line of soles in red, black and white rubbers of difl'ercnt 

 grades. [E^sex Manufacturing Co., Inc.] 



A company in the west has manufactured a "metal hot water 

 bag" that is claimed to be superior to those made of rubber. In 

 shape this "metal bag" resembles those of rubber. It is flexible, 

 bnt will not stretch. There are two covers, the outer one of soft 

 cloth, easily removed when the whole force of the heat is de-
