WATERPROOF COVERS FOR THE MOTORIST. 



Storm aprons or protectors of some kind are necessary fea- 



tures of the automobilist's outfit, and since the opening of the 



pre '-nt season 

 ome excellent 

 in 1 1 d e I s have 

 ln-i-n show n . 

 The cut here- 

 with illustrates 

 a storm apron 

 which is made 

 in sizes from 

 the two -pa 

 senger runa- 

 bout to the li\ L-- 

 passenger large 

 tonneau size, at 



prices fn m plO I $15, ot rubber cloth These aprons have slip 



openings with yoke collars fitting closely around the neck, with 



snaps for cli -ing in case the car is left vacant during a shower, 



the apron lining the car perfectly and being absolutely water- 

 Each apron i^ packed in a water] i bag suitable for 



storing away when not in use. [The Gilbert Manufacturing Co., 



New Haven, Connecticut.] 

 'I lie other cut shows a waterproof protector of similar nature 



for the motorcyclist. This is in 



the form of a cape, made of 



light weight raincoat rubber 



cloth, affording protection to the 



machine at the same time that 



it shields the rider from rain, 



mud and cold. It has fastenings 



to hold it over the handle bars, 



and is so arranged that it does 



not inconvenience the wearer in 



dismounting. It can also be folded compactly for carrying. 



[Nathan Novelty Manufacturing Co., 84-90 Reade street, New- 

 York.] 



THE -SLIPKNOT" RUBBER HEEL. 



The demand tor rubber heels is engaging the attention of 

 many of the large manufacturers of rubber goods, and as shoe 

 styles increase in number and variety, the more rubber heels are 

 needed. The "Slipknot," though a comparatively recent addition 

 to the supply of heels on the market, has been well received, 

 the features which it is claimed have contributed to this favor- 

 able reception being its uniform composition, durability and 

 correctness of size and shape. [Plymouth Rubber Co., Canton, 

 Massachusetts I 



THE DIAMOND ACE GOLF BALL. 



This ball, the latest type brought out 

 by the manufacturers of a long line of 

 golf balls under the "Diamond" and other 

 brands, is said to have the endorsement 

 of some of the best-known professionals 

 oi the country, to have perfect flight and 

 an extremely long carry and wonderful 

 roll, besides being durable and retaining 

 its shape. [The Worthington Ball Co., 

 Elyria, Ohio.] 



The "Kewpie" is a new side garter for children, both the 

 single top section and the double suspender ends being of elastic. 

 These are joined by buckles of rustless nickeled brass similar to 

 the clasps. The garter is attached to the child's waist by a 

 "pin that locks," said to be an exclusive feature of this garter. 

 Each pair is put up in a sealed envelope. [Arthur Frankenstein 

 & Co., 516 Broadway. New York.] 



AUTOPNEUMATIC INNER TUBE. 



This inner tube, instead of being one continuous air chamber 

 as is the case with the ordinary inner tube, consists of a number 

 of sectional piei es ol tube, 

 requiring from 12 to 20, ac- 

 cording to the si/r oi tlii 

 wheel, to constitute a com- 

 plete tire. '1 i tional 

 pii i es or individual rubber 

 bags are all joined to a 

 .11 circular metal tube 

 u Imh acts as an air supply 

 conduit. 



i ' h bag or section is 

 si i i'u ed to a valvi let e-\ ery 

 4 inches along the outer 

 circumference of this con- 

 duit. By a turn of the 

 control stem, each valve is opened to the main conduit, th( 

 making the separate sections practically one inner tube. Then 

 the air is pumped through the main valve stem until the required 

 air pressure is obtained, which will be the same in every section. 

 By turning back the control stem, each valve is closed, and each 

 section becomes an independent unit. 



In case of a puncture, the 4-inch hag which has been punctured 

 collapses, and each adjoining sack or section will expand, taking 

 the place of the punctured bag. Tests have demonstrated that 

 five or six punctures may be made before it is necessary to stop. 



To remove the punctured bag, the air control stem is turned, 

 which opens all the valves, and partly deflates the inner tubes. 

 By means of a special tool provided for the purpose, the edge 

 of the shoe immediately over the punctured section is raised, 

 the punctured bag removed and a new one screwed in place. [G. 

 y. Baillard, 251 East Thirty-first street, New York.] 



THE "NOAIR" COMPRESSION TIRE. 



The "Xoair" is a new tire which costs about the same as the 

 high grade pneumatic, but which, it is claimed, gives 17,000 miles 

 of uninterrupted service and saves the cost of shock absorbers, 

 the strain on the car and also accident insurance. The tread of 

 this tire, which is made of solid rubber, is lined with steel. The 

 rim rests on a crown of rubber, which is supported on a resilient 



suspension, so that all shocks are absorbed inside the tire. This 

 tire has a purchase on the rim which is mechanical and does not 

 rely on inflation. It has the tenacity of the solid tire, without 

 either wire or fabric and, also according to the claim of the 

 manufacturers, will sustain a maximum compression that would 

 burst a pneumatic tire. [W. J. Spencer, 1504 Green street, 

 Philadelphia.] 



A NEW JENKINS DISC. 



A new disc made of rubber composition and to be known as 

 the "Jenkins Bros. Xo. 119," has just appeared on the market, 

 after a series of tests which are said to have shown the com- 

 position to be hard, but tough and flexible under service when 

 in steam pressure; to possess freedom from cracking and flak- 

 ing and durability in working steam pressures up to 150 pounds. 

 This new composition will hereafter be used in all of the manu- 

 facturers' standard pattern globe, angle, cross and radiator valves 

 when intended for steam service. [Jenkins Bros., Elizabeth, 

 Xew Jersey.]
