Airless Clinches Tire. 



[View of the Casing.] 



NATIONAL AIRLESS CLINCHER TIRE. 



The tire illustrated here is made of rubber and fabric, so far 



as the casing is concerned, the same as the ordinary clincher 



pneumatic. Instead of being hollow, however, like a pneumatic 



casing, the tire has a partly 

 solid interest construction, as 

 shown in the cuts. This inner 

 construction shows a series of 

 spherical cavities at short in- 

 tervals, separated by pieces of 

 solid rubber. These pieces 

 spread at top and bottom, thus 

 giving the truss the element of 

 strength. The cavities go 

 clear to the rim. When 



mounted on the car the tire has the appearance of a pneumatic. 



It is referred to as being resilient and easy on both machine and 



passengers, though 



slightly slower than a 



pneumatic. The inner 



construction is not sep- 

 arate from the outer 



casing, but the tire is 



built up from this core 



and the whole tire is 



cured in one mass.

LIFE SAVING AND SWIMMING APPARATUS. 



The appliance illustrated here is of the class in which buoyant 



bodies are enclosed in net 

 bags connected together by 

 straps. The buoyant bodies 

 are permanently inflated, and 

 have an airtight and water- 

 tight covering. In this case 

 hollow rubber balls are se- 

 cured in bags, as described, 

 and connected to the two 

 ends of a strap; or the strap 

 may have free ends, to one 

 of which a buckle is attached. 

 More than ball may be placed 

 in each bag. Patented by

 ony. 



"CANT-SLIP" RUBBER HEEL. 



A distinctive feature of the rubber heel illustrated here is a 

 piece of extra quality rubber at the tip of the heel where the 

 greatest wear comes. This is referred to as adding at least 

 one third to the service of the heels. Another feature is the 

 air chamber between the leather and the rubber heel which

keeps the opening clear, and produces a continual suction, 

 thereby preventing the wearer from slipping. These heels are 

 made under the patents of W. G. Anderson, by Converse Rub- 

 ber Shoe Co. (Maiden, Massachusetts), who have been adding 

 to their factory capacity to enable them to produce this new 

 line of goods.

 In the fitting out of plantation rubber factories outfits for 

 drying are essential, and under this heading may be mentioned 

 the strong, serviceable drying rack illustrated on this page. These

racks are supplied complete, including iron framing and gal- 

 vanized wire netting. The netting can be obtained also for fitting 

 to existing racks. [Boulton & Paul, Limited, Norwich, England.] 



HEALTH IN RUBBER FACTORIES. 



IN a certain important rubber manufacturing center in New 

 * England complaints have been made of the number of em- 

 ployes, particularly girls, who leave, as is alleged, on advice of 

 physicians. The superintendent of one factory, interviewed by a 

 local newspaper, is quoted as saying: 



"It is true we have found many physicians have advised their 

 patients to quit working in the rubber shops if they wished to 

 recover. We employ many girls and if one of them goes to a 

 doctor complaining of a headache, he will ask her where she 

 works and when she replies, 'In the rubber shop,' he will shake 

 his head and say, Well, you'll have to stop working there before 

 I can do anything for you.' 



"Such an idea is absurd. I invite any physician and the board 

 of health to come down to our shop at any time to see whether 

 it is not fit to work in. 



"It is a great injustice to us. It makes it hard to get people to 

 work for us, as such reports spread and many become frightened. 

 The fact of the matter is that some of our employes have been 

 with us for many years and are in first class health. I know 

 of one girl who has worked in the shop for the past fifteen years 

 and is even more healthy than when she began." 



An Unsatisfactory Water Bottle. — "I trust you slept com- 

 fortably and had everything you needed?" said Sandy Macpher- 

 son's hostess one cold morning last winter. 



"Ay, wecl enough," replied her guests, a venerable Scot; 

 "but I dinna see the guid of yon bottle in the bed." 



"Why, wasn't the water hot?" the hostess asked in surprise. 



"Verra hot," responded Macpherson, "but ye forgot to put 

 anything in it." — Scraps.
