THE INDIA RUBBER WORLD

A NEW INNER TUBE BY GUSTAVE RUSH. 



Mr. Gustave ECush, of New York, the well known manu- 

 facturer of mechanical rubber goods, has invented an inner 

 tube which certainly is unique and original. The first 

 the two accompanying illustrations shows this tube placed 

 in the casing and only sufficiently inflated to hold its natural 

 shape. It will be noticed that at the tread there are three 

 longitudinal ribs, very much wider at the top than at their 

 base. When the inner tube is fully inflated it assumes the 

 shape shown in figure No. 2, when- it will he seen that the 



ribs overlap and form several chambers in which the air be- 

 comes compressed when the tube is inflated. This inner tube 

 weighs about one-third more than the ordinary kind, but it 

 will be possible with this tube to use a casing about 25 per 

 cent, thinner than the usual casing. 



It is obvious at a glance that this tube makes the tire much 

 less liable to puncture than the ordinary tube which has the 

 same thickness at all points. In addition to this merit Mr. 

 Kush claims that by reason of the compressed air caught be- 

 tween the ribs and the decreased thickness of casing required 

 the tire becomes more resilient. His further contentions are 

 that there is no pinching or friction between the tube and the 

 easing, and much less liability to over-heating. Me believes, 

 further, that with this tube pneumatic tires can be used on 

 heavy trucks in place of solid tires to great advantage and with 

 much economy. [Gustave Kusk. 61 Beekman street, New York.] 



THE COATS RESILIENT WHEEL. 



Many tires have been designed with the object of eliminating 

 the pneumatic tube feature and preserving the resiliency, but 

 the Coats wheel preserves the pneumatic cushion effect in a 

 novel manner by distributing. the air in six pneumatic bags placed 

 around the hub. As shown in the illustration, each of these 

 air hags is a circular cushion, placed between the hub and the 

 rim. The rings are 

 inflated simultaneously 

 from an air valve near 

 the center of the wheel, 

 and are inter-connect- 

 ed by flexible tubes so 

 that a road shock on 

 one is distributed 

 among the six. The 

 rings are enclosed by 

 cover plates on the 

 sides of the wheel and 

 are thus protected from 

 oil, moisture and light. 

 Should one of the cush- 

 ions become deflated, 

 the wheel could still be used, or the cushion replaced in a few 

 minutes. Since the cushions do not come in contact with the 

 mad, they are not subjected to wear. The rim is made in S. 

 A. E. standard sizes and will take standard solid tires. [Ameri-

A PNEUMATIC TUBE WHERE IT CANNOT BE PUNCTURED. 



A Louisville company has put a combination wheel and tire on 

 the markel ol such .i character thai the tire, while pneumatic, is 

 not subject to punc- 

 ture, it is 

 far remo 



whei i' anj puncture 

 is possible. I h I 

 wheel .has a 

 rubber tire, li 



cushii med hub. 

 - ii isting of an in- 

 ner and an outei 

 circle; and bet 

 these there is in 

 ed an annular in- 

 flat e d e u S h i o n 

 which, as a mattei 

 of fact, is a small 

 size pneumatic tire, 

 but, b e i n g plai < 'I 

 where it is, it is immune from the accidents that befall the pneu- 

 matic tire in its usual place around the rim. The accompanying 

 illustration shows the location of this new pneumatic. [Pneu- 

 matic Hub-Tire- Wheel Co., Louisville, Kentucky.] 



THE SHERRIN-DIAMANT TIRE. 



An innovation in the construction of solid rubber tires is 

 presented in the Sherrin-Diamant tire illustrated herewith. 



From external appearances it 

 seems to be of about the same 

 construction as the average 

 solid tire, although it is said 

 to combine the resiliency of 

 a pneumatic with the advan- 

 tage of being puncture proof. 

 The inside is hollow and the 

 lower edges set in the rim of 

 the wheel in the ordinary 

 manner. There are two ribs on 

 the inside extending around the 

 tire, and these are laced to- 

 gether by a raw hide thong, 

 which supports the lateral 

 walls but allows sufficient re- 

 siliency to take up the road 

 shocks. [The Sherrin-Diamant Tyre Syndicate, 10 Copthall 

 avenue, London, England.) 



THE "NO-STRETCH" TIRE BOOT. 



A new type of tire boot, known as the K. C. "No-Stretch," has 

 been introduced in the West. Ibis boot is built on a core the 

 exact shape of a tire, in quarter-inch sizes, so as to fit non-skid 

 tires, and in 

 both hook ■ 

 and lace- 

 styles. I t 

 constructed 

 two inner layers 

 of rubberized 

 tire fabric and 

 an outside layer 

 of leather. The 

 no-stretch fea- 

 ture is the result of the use of the rubberized fabric, which resists 

 the action of water, while the studded leather cover supplies 

 wearing quality. It is guaranteed by the manufacturers to give 

 2.000 miles service. [Western Tire & Rubber Co., Kansas City,
