Aeriu'lane Ci-ixniFR Tire. 



The illustration shows an aeroplane wheel and tire manufac- 

 tured by the Pennsylvania Rubber Co. (Jeannette, Pennsyl- 

 vania). Aeroplane tires, in spite of the fact that they work 

 only when the machine is starting and alighting, undergo some 

 service. The rush of the start, and the ofttimes hard shock of 

 landing, call for strength and toughness. A weak tire might 

 burst and cripple the machine. In their cloud journeys they are 

 idle and do not pick up nails, nor is the aerial skidding ever laid 

 to them. Two styles are in vogue, those with a leather tread, 

 and the ordinary rubber surfaced tire. So far no aeronaut has 

 complained of heating; indeed, after a flight the surface of the 

 tire is often as cold as ice. 



THE OKANUS FACE WATER BOTTLE. 



The O'Kanus brand of water bottles and like goods are made 



up in various colors, to suit 

 the tastes of buyers — -white, slate, 

 white-slate trim, and slate-white 

 trim. All the goods of this brand 

 are packed in flat telescope boxes, 

 with a new form of hinged plat- 

 form for fittings. An interesting 

 item in this line of goods is the 

 O'Kanus face water bottle, made 

 in the same way as the larger bot- 

 tles in this line. The shape of the 

 face water bottles is admirably 

 adapted for the purpose for which 

 they are intended. They are made in 

 tliree sizes — one-fourth pint, one- 

 half pint, and one pint. By the 

 way, these bottles are recommend- 

 ed also for infants. [The Miller 

 Rubber Co., Akron, Ohio.]

RUBBER GOODS IN AVIATION. 



In connection with the aviation meet at Belmont Park, near 

 New York (October 22-30), were exhibited a great variety of 

 aeroplane engines, propellers, and appurtenances. Of special in- 

 terest to rubber men were the exhibits in their own line. 



For example, the Goodyear Tire & Rubber Co. (Akron, 

 Ohio) exhibited a full line of tires for aeroplanes, together with 

 aeroplane and balloon fabrics. 



The Hartford Rubber Works Co. showed three types of single 

 tube aeroplane tires, called "the Hartford .\viator," ".'\eropIane," 

 and "Aeronaut," respectively. They had on exhibition also Hart- 

 ford clincher airship tires in regulation sizes. The Hartford Aero 

 varnish was another specialty that was evident in their exhibit. 



The new Century Rubber Trading Co. showed a full line of 

 automobile tires which were explained by Mr. Nathan Baruch. 



An interesting exhibit was that of aviator cord and aviator 

 wire, made by John .'\. Rocbling's Sons Co. (Trenton, New- 

 Jersey). 



THE BALDWIN AEROPLANE FABRIC. 



For aeroplanes and balloons a silk double walled, vulcanized 

 fabric, claimed to have ten times the wear of varnished stuflfs 

 used, has been accepted by the United States government for 

 balloons, dirigible and spherical. This material, it has been 

 proved, requires little care, is not subject to spontaneous com- 

 bustion, will not crack and is of course waterproof. Its break- 

 ing strain is 100 pounds per inch width. [Thomas S. Baldwin, 

 Madison Square, New York.] 



AVIATION SUITS. 



The man who runs an aeroplane oftentimes gets very wet and 

 cold, unless properly clothed. To be anywhere near comfortable 

 he must be encased from top to toe in waterproof and cold- 

 proof clothing. Such clothing must, moreover, be light, flexible, 

 and not bulky. Suits of very light waterproof leather are often 

 worn. What interests the rubber trade more, however, are the 



The "J. M." Aviator Suit. 



double textured suits made of special tweeds, extra light in 

 weight, and absolutely wind and weather proof. The illustra- 

 tion shows one of these suits which is known as the "J. M." 

 aviator suit and exhibits its construction so well that no explana- 

 tion is necessary. [J. Mandlebcrg & Co., Limited, Manchester, 

 England.] 



FRENCH AVIATION CLOTHING COMPETITION. 



The Ligue Nationale Aerienne have organized several com- 

 petitions with the object of rendering aviation safer and pleas- 

 anter. One of these competitions is for protective clothing 

 from wind, cold, and water, for the aviator. 



CRAVENETTE POPLIN. 



PoPLiN, a popular fabric for ladies' and children's gowns, is 

 made of cotton but is very silky in appearance. "Cravanette 

 Poplin" is the same material, but is water repellent, stainproof.
