A TIRE PRESERVER. 



Where a tire shows weakness or has blown out it is frequently 

 discarded, although there may still be a good wear in it. Com- 

 paratively few tires wear through on the treads before they give 

 out on account of fabric breaks. The fabric breaks that are on 

 the inside of the casing cause the tube to chafe and it gives way 

 when least expected. In the accompanying illustration is shown 

 a device by means of which a tire showing signs of weaknes.s is

strengthened and its life prolonged. Made endless, of several 

 plies of fabric and rubber vulcanized together and molded to fit 

 the inside of the casing it is coated on the outside with cement 

 so that when the tire heats by friction in running it becomes part 

 of the casing itself and makes its interior as smooth as when 

 new. Easily inserted and reasonable in cost it goes a good way 

 to prevent tire troubles and adds life to the lire. It can be 

 obtained in 20 sizes, ranging from 28 x 3 to 36 x 5 and makes the 

 casing good untilcomplctely worn out. [Boston Tire and Rubber 

 Co., No. 184 Friend street, Bostnn.] 



A NEW "KNOCK' LOCATOR. 



When the human machine goes wrong and the truuble is not 

 easily apparent, the physician attaches one end of a stethoscope 

 to his ears, and sounds various parts until the seat of the trouble 

 is located'. Some such reliable device for machines not Inmian, 

 such as automobiles has long been needed. It is found in the

vibracator, which is a scientifically designed sound intensilier. It 

 is made of rubber and metal. In use the ear tips arc put into 

 the ears so as to shut out external sounds, then the corrugated 

 diaphragm head is placed against the machine case and moved 

 about until the sound is absolutely located. By the way, the 

 device is of use in any factory particularly in locating pounding 

 in steam engines due to water in the cylinder, loose packing 

 rings, or defects in valve seting. [Hopewell Brothers, Newton, 

 Massachusetts.] 



AUTO AND AVIATION WRAPS. 



Among the ladies' new wraps for aeroplaning or motoring dis- 

 played at John Wanamaker's store are some very smart imported 

 raincoats. One, called the "Bleriot" is of heavy corduroy, dark 

 green or brown, and with a rubberized lining; another, the 

 "Mercedes," and the "Simplex" are of silk rubber; the "Renault" 

 of satin rubber and the "Cycliste" of crepe de cygne. These last 

 are in colors of tan, champagne and blue, and are not expensive 



RESULTS OF THE GRANT PATENT DECISION. 



'T'HE action of the Consolidated Rubber Tire Co. concerning 

 ■*• infringers of the Grant patent is awaited in the trade with 

 considerable interest. Naturally neither the company nor the 

 15 or more rubber companies that are said to have been making 

 solid tires that infringed are explaining their respective positions. 



The Grant patent has some two years yet to run and it is a 

 question whether either side would take much interest in licenses, 

 although it is understood that the Consolidated company has no 

 (il)jcctions to granting them. Damages, if granted, would be 

 assessed for a period covering six years from the present time, 

 in case suit had not been brought previously. Some, however, 

 were instituted about four years ago which w^ould make the 

 lieriod ten years. 



The company seemed to be engaged in conference with various 

 solid tire manufacturers with the idea of getting an estimate of 

 the pondage made by each company during the last 6 to 10 

 months. F'or a guess the plan is to be able to secure through 

 damages at least enough to remunerate the company for its very 

 expensive law suits which have been industriously prosecuted 

 for some years past. 



The historic Grant i)atent was issued tn .Krthur W. (irant. 

 February 18, 1896. It has been the suljject of much litigation. 

 The patent was sustained in the following cases: The Rubber 

 Tire Wheel Co. vs. The Columbia Pneinnatic Wheel Co.; the 

 Consolidated Rubber Tire Co. vs. I'inlay Rubber Tire Co. ; the 

 Consolidated Rubber lire Co. vs. Firestone Tire & Rubber Co.; 

 the Rubber Tire Wheel Co. vs. Milwaukee Rubber Works; the 

 Diamond Rublier Co. of New York vs. the Consolidated Rubber 

 Tire Co. The patent was also declared valid in the Circuit 

 Court of Appeals of the Republic of France, sitting at Paris, in 

 1902. It was held invalid in the Gooyear Tire & Rubber Co. et 

 al., vs. the Rubber Tire Wheel Co., and in the Rubber Tire 

 Wheel Co. vs. Victor Rubber Tire Co.
