NEW GOODS AND SPECIALTIES IN RUBBER. 



T 



A NON PUNCTURABLE PNEUMATIC TIRE. 

 HE cut herewith illustrates the cross section of a new 

 punctureless and non collapsible pneumatic tire de- 

 signed to meet the wants of a considerable number of 

 persons whose experience with the ordinary pneumatic 



tire has not been wholly 

 satisfactory. The tire 

 embraces a central rub- 

 ber core, and two air 

 chambers. The rubber 

 core lessens the danger 

 of punctures to a mini- 

 mum and overcomes en- 

 tirely the danger of col- 

 lapsing, as the tire runs 

 upon the core. In case of the puncture of one of the air 

 chambers, only that one can become deflated, and there still 

 remains two-thirds of the tire to ride upon. Leakage around 

 the lugs is prevented by the lugs being embedded in the cen- 

 tral rubber core, entirely away from the air chambers. The 

 tire is inflated by means of a single valve, which connects with 

 each of the two chambers. This tire has been patented in sev- 

 eral countries — the United States patent being No. 745,040, 

 November 24, 1903 — by Dr. T. J. Cooper, Paterson, New Jersey. 



WILLIAMS NON SLIPPING TIRE. 

 Among the new features in tires exhibited at the recent 

 cycle shows in England was Williams's patent " Uvula " rub- 

 ber tire for motors, fitted to an 

 open channel by means of a pat- 

 ent adjustable band and fasten- 

 ings. A cushion tire with an 

 uvula shaped buffer between the 

 tread and the steel band ; the 

 band is passed through the bed 

 of the tire clamped into the steel 

 channel. In the event of the tire 

 being damaged, a section can be 

 cut out and a new piece inserted. A sectional view of the tire 

 is illustrated herewith. The advantages of a pneumatic tire, 

 with regard to resiliency, are claimed, with a superior degree 

 of rigidity, greater durability, and freedom from creeping, roll- 

 ing, or side slip. [The Williams Tyre Co., 4, Denman street, 

 Piccadilly circus, W., London.] 



" KLEEN INSIDE " NURSING BOTTLE. 

 The difficulty of cleaning the inside of the ordinary nursing 

 bottle, and keeping it clean, suggested to the inventor of the 



bottle illustrated 



V 



I 



herewith the idea of 

 a milk receptacle, 

 every part of which 

 is easily accessible. 

 It may be made in 

 the shape of an ordi- 

 nary flat oval nursing 

 bottle — but it differs 

 from all others in be- 

 i ng made in two 

 pieces, one side lifting off the other like the lid of a box. The 

 joint is made tight by means of a rubber washer. The two sides

are held together by a metal clamp that snaps on in a moment 

 and can be removed instantly, though the spring is too strong 

 for an infant's fingers to open. It is intended to retail at 25 

 cents. [Lee Anderson, No. 97 Chambers street, New York.] 



"DR. HALL'S MAGICAL SYRINGE." 

 A new spray syringe, patented in the United States Septem- 

 ber 1, 1903, has been placed upon the market under the name 

 given above. The features in 

 this contrivance claimed to 

 be new are the changeable di- 

 rections of the sprays from 

 the nozzle. In fact, the en- 

 tire novelty of the new con- 

 struction is in the nozzle. 

 For the rest, the syringe is 

 an ordinary soft rubber bulb, 

 attached directly to the hard 

 rubber nozzle. There are no 

 valves, no pistons, no rubber 

 tubes ; the whole construe- - 



tion is simple and there is no liability of any part to get out of 

 order. At the end of the hard rubber tip, however, there is a 

 movable nozzle which screws on to the end of the tip, and its 

 position is reversible. When screwed on in one position it 

 throws a radiating spray forward, and when screwed on in a re- 

 verse position, the spray is thrown backwards. The merit 

 claimed for this appliance, giving as it does a douche both 

 forward and backward, is that it is thoroughly cleansing in its 

 effect. The syringe is also fitted with a shield of soft rubber, 

 which prevents any leaking and adds to the convenience of 

 its use. One more feature is that the construction of the 

 syringe prevents the injection of air. [The Vant Woud Rub- 

 ber Co., No. 88 Reade street, New York.] 



"ALL RUBBER" STAMPS. 

 THIS is a new line of rubber stamps, made without the use of 

 any metal or wood, but of rubber throughout. Among the ad- 

 vantages claimed for such stamps is 

 their durability, as compared with 

 other styles; their adaptation to 

 rapid work and hard usage ; and the 

 production of uniformly good prints. 

 If struck carelessly or quickly the 

 impression is not spoiled or blurred, 

 as the pressure is equalized and 

 there is no rebound. The wear to 

 stamps and noise of stamping is re- 

 duced. They will not break when 

 dropped, and are claimed to outlast 

 stamps mounted on rigid handles. 

 Besides, they are light in weight 

 and restful to the hand, which is an 

 item of importance to railway postal 

 clerks, for example, whose work is 

 practically continuous for long per- 

 iods of time. Patent No. 732,236, 

 issued to Eugene M. Tilden, June 

 30, 1903. Leading stamp manufac- 

 turers have been licensed under the patent. [Lamb & Tilden, 

 No. 525 Tenth street, N. W., Washington, D. C]
