THE INDIA RUBBER WORLD 



April 1, 1913. 



TR£ ST. LOUIS CO.'S KOTCH ELECTBIO TIBE. 



About three years ago Mr. J. A. Swinehart, who had been for 

 some time connected with a tire manufacturing concern, retired 

 from the business. But once a tire man, evidently always a tire 



man; and Mr. Swinehari 

 was not able to keep his 

 mind from the great tire 

 problem. As a result he 

 has evolved a tire which 

 he has called the Notcli 

 Electric Tire, and which 

 is being manufactured 

 by the St. Louis Tire & 

 Rubber Co., of St. 

 Louis, of which Mr. 

 Swinehart is vice-presi- 

 dent and manager. The 

 accompanying cut gives 

 something of an idea of 

 this "Notch" tire. These 

 notches are inserted 

 alternately at regular intervals on a slant of about 20 degrees. 

 They serve to give tlie solid tire more spring and resiliency. 

 and according to Mr. Swinehart, they serve another very im- 

 portant purpose. Where the car is running on a smooth but 

 muddy road-bed, these notches serve to push the mud or mois- 

 ture to one side so that the smooth tire has a clean smooth 

 surface to operate on, and thus avoid skidding. Moreover, these 

 notches serve an excellent turn in city streets, as they make it 

 easy for a car to get out of a street car track when it is wet. 

 Mr. Swinehart's new company not only makes this notch 

 cushion tire, but is manufacturing truck tires of the flange type, 

 and also a pneumatic tire on a new principle, which provides 

 for the expanding of the carcass within the mold by hydraulic 

 power, so as to insure against b\ickling or pinching of the fabric. 



EUBBEK SEAL FOR BOTTLED LlftUIDS. 



Bottled liquids have come into such general use for domestic 

 as well as outdoor purposes, that to keep them secure, and 

 at the same time free from exposure to air, has become a mat- 

 ter of daily necessity. These ends have been accomplished by 

 the "Brownie Cap," an absolutely sanitary rubber seal for bot- 

 tles, which is quickly 

 cleansed and sterilized 

 in hot water. The rub- 

 ber is always pliable and 

 effectually protects the 

 liquids from germs, dust, 

 vai)ors and foul air or 

 odors. 



While this cap thus af- 

 fords full protection for 

 liquids, it can be easily 

 slipped on or off, and is 

 thus specially adaptable 

 for use on picnics, excur- 

 sions and camping trips. 

 It is also most valuable 

 for the purpose of sterilizing milk intended for babies and, 

 owing to its airtight clinching under the collar, permits the bottle 

 to be placed in any position on the ice, without risk of leaking or 

 spilling. 



A REMEDY FOR C1L4FING. 



Insulated wire and rubber gas tubing are liable to become 

 chafed by passing through holes in sheet metal. This can be 

 prevented by short pieces of heavy rubber and fabric tubing 

 slipped over the former, and held in place by a little rubber 

 cement. 



A LITTLE EUBBEE TUB FOB. BABY. 



How to bathe that member of the family usually flippantly 

 referred to as the "kid," has always been something of a 

 conundrum. Obviously it would not do to fill a bath-tub full 



The Baby's B.\th Tub. 

 of water as the child might go under, and to bathe him in 

 a few inches of water in the bottom of the tub is a back- 

 breaking process for the mother or nurse. But here is a bath- 

 tub designed especially to meet the situation. It is a flexible 

 rubber tub, just the baby's size, on a rigid steel frame that fits 

 on the side of any bath tub. This tub within a tub can be 

 filled from the faucet and emptied into the tub, which obviates 

 all carrying of water. The child gets all the depth of water 

 necessary, and can tumble around in the tub without being 

 injured in any way, while the nurse can stand or sit during 

 the bathing operation in a comfortable position. [The Heaton

PERFECTION NON-SKID CLIMBER. 



The adaptation of motor vehicles to commercial uses has- 

 resulted in the presentation of various difficulties, prominent 

 among which is that of skidding. While this problem is a 

 troublesome one under all circumstances, it 

 becomes doubly so in the case of motor- 

 trucks where the weight of the load is naturally 

 heavy. 



With a view to remedymg these troubles 

 the "Perfection Non-Skid Climber" has 

 been introduced, in which the shoes or 

 treads are made from fine drop-forged steel, 

 treated with heat, connected to Swedish 

 iron side chains by steel side-links. The 

 shape of the shoes prevents them from in- 

 juring the tire. Tires can be worn down 

 to the rim without altering the shape. 

 The cross-shoes having two flexible joints, 

 there cannot be any permanent distortion- 

 of any of the parts, the tread freely adopt- 

 ing itself to the surface of the road. There 

 are no chains over the tire to collect sand and gravel to cut 

 into or wear it. The device is marked by simplicity of con- 

 struction. Ease of adjustment and infallible action are also- 

 claimed for it. It has but three working parts, can be easily 

 and quickly put on and taken off; operating on a simple 

 mechanical principle which automatically checks all sliding,, 

 skipping and skidding. [Perfection Non-Skid Climber Co.,
