RUBBER IN CAR WHEELS. 



THE ii ii "i rubbei into cai wheel con truction opens 



a ticM of interesting possibilities to the rubber manufac- 

 turers. Such a wheel has not onlj been designed and 

 patented, but has been in use since early in April and is said 

 to have substantiated the claims of die inventor for the 

 elimination of the rattle and jar of the ear This Madden 

 Silent Wheel is constructed oil the principle of a wheel within 

 a wheel, the curved recesses preventing the inner wheel from 

 Iving except as the outer one revolves. The two wheels 

 are separated by a rubber cushion, as shown in the white 

 curved line in the interior view of the wheel, the other view 

 showing the wheel with side plates attached to In. hi the inner 

 wheel in position and prevent side motion. 



The wheel itself is designed to give 300.000 miles service, 

 and the rubber inner tire or cushion, as well as the outer 

 wheel tread, can he replaced when worn out. The wheels at 

 present in use have already run over 7,000 miles, and they 

 .or --till running in test service. The makers believe that the 

 rubber cushion can he greatly improved, and they invite the 

 co-operation of rubber manufacturers toward this end. Vs 

 26 pounds of rubber is used in each wheel, with eight wheels 

 to a car. and as there are in use in the United States at the 

 present time about 100,1 I it t trollej ears and 00.000 railway 

 passenger cars, besides about 2.500,000 freight cars — for all of 

 which this wheel is adapted — its adoption bj tin- street and 

 steam railways throughout the country would mean a urcat 

 increase in rubber consumption. [Madden Silent Wheel Cor-

THE ANGLE-TREAD NON-SKID TIRE. 



The usual procedure in tire manufac- 

 ture in the past has been to 1mm- the 



kid portic f the tread rim abi 'in 



half way down over tin- side walls, be- 

 ■ he point w here it a imes in con 

 tact with the road. The illustration 

 shows a type of tire in which this cus 

 torn is not followed, but where the ■ 

 is made higher in the center, where the 

 lire is subjected to the mo>t wear. This 

 feature, and a scientific arrangement of 

 the corrugations, at e sup; , ,,, ,\ to add 

 considerably to the tire's wearing quali- 

 ties. [The Marathon Tire & Rubber

•INDESTRUCTIBLE'' GASOLENE HOSE. 



The em In low. a photographic reproduction of a section of 

 a new type of "Indestructible" hose, nils its own story. The 

 manufacturers of tins hose are guaranteeing it to withstand 

 i lie action of gasolene and oil ami offer to replace it without 



charge if it becomes unserviceable from the action of gaso- 

 len< ; ami the hose is so branded, the guarantee providing, 

 however, that it must not he used for any other purpose than 

 conveying gasolene and oil. [New York Belting & Packing

THE "BESTYETTE" WATER BOTTLE. 



This is a seamless, narrow-neck bottle, made of tough and 

 durable rubber stock over a solid core. The stopper is integral 

 w ith the bottle and is not wired to the 

 neck or held in place by a piece of 

 friction tape, hut is really part of the 

 article itself. 



The unusual qualities claimed for 

 this bottle by the manufacturer are 

 demonstrated by a series of mo el 

 tests. The bottle is inflated until it is 

 five times its normal size, subjected to 

 an air pressure of forty pounds ; then 

 two men stand on the inflated bottle, 

 which stands this severe test without 

 rupture or break. The illustration 

 was made from a photograph ot a 

 "Bestyette" bottle taken after being 

 subjected to the above mentioned tests. 

 It will be seen that it retains its uni- 

 formity and has not lost its shape.

NEW RUBBER BALLS. 



The cut below illustrates three balls that have just come "ii 



the market, although the design of two of them, the "Campo" 



and the "Scouto," was mentioned on page 194 of our January 



These two balls, as their names imply, were designed for 



use by the Camp Fire Girls and the Boy Scouts, two very popular 



organizations whose membership now includes a large num- 

 ber of the young people throughout the country. On the Lamp. 

 hall, the words "lit Happy. Give Service" — two of the seven parts 

 of the club law — appear in raised letters on a hand around tin- 

 center of the hall; on the Scouto are the words "Do a Good 

 Turn Daily." The blanket ball in the center is in bright colors in 

 plaid effect. [Goodyear Rubber Co.. Milwaukee, Wisconsin.]
