THE INDIA RUBBER WORLD 



[April i, 1904. 



A NEW VEHICLE WHEEL TIRE. 

 The illustration relates to a new detachable pneumatic tire 

 and to means for securing the outer cover of the same in posi- 

 tion on the wheel rim. It is the 

 subject of United States patent 

 No. 753.426, granted March 1, 

 1904, to Harry A. Palmer, of 

 Erie, Pennsylvania. The patent 

 covers the combination, in a ve- 

 hicle wheel, of a wheel rim ; a 

 metal tire thereon ; flange rings 

 secured to the sides of the wheel 

 rim so as to form a peripheral 

 channel thereon ; a pneumatic 

 ttre sheath provided with a slit 

 on its inner face, and adopted, to 

 inclose an inner tube, and fit 

 into the channel on the wheel 

 rim ; clamping rings on the inner 

 faces of the sheath opposite the 

 sides of the channel on the wheel rim ; and bolts passing 

 through said clamp rings, the sides of the sheath, and the 

 flange rings. A modification of the same patent claim relates 

 to the holding in position of solid rubber tires. 



THE " STITCH-IN-TIME " VULCANIZER. 

 The name adapted for the device illustrated herewith is 

 based upon the adage that " a stitch in time saves nine," the 

 idea being that many serious troubles with pneu- 

 matic result from the neglect of small cuts or 

 punctures which might, with an inexpensive ap- 

 paratus, be repaired with ease and promptness. 

 The " Stitch-ih-Time " vulcanizer is now made 

 in sizes applicable to patches as large as 2^X3^ 

 inches. It may be operated in repairing a tire 

 without removing it from the rim, the method 

 being indicated in a measure by the illustration. 

 The vulcanizer has a thermometer to register the correct heat, 

 and the lamp has a flame regulator to hold it at this point as 

 long as necessary to complete the work. It may be used also 

 to heal up small rents or cuts on solid rubber tires. The price 

 is $5, including a supply of material for a dozen repairs. The 

 apparatus weighs only 5 pounds. Patented by J. M. Padgett.

 BOOK FINISHERS "GOLD RUBBER." 

 It is well known that book finishers, both blank and 

 printed, use a great amount of gold leaf. Their scrap 

 is in the form of little bits that it would be almost 

 impossible to collect and save, were it not for the use 

 of " gold rubber." In its most primitive form, as it 

 is made by the finisher, it is a ball of uncured pure 

 gum that by the admixture of oil and the application 

 of heat has been formed into a sticky ill smelling mass. 

 Itonly needed a practical rubber man to produce 

 something that would have all of the virtues of the 

 old and none of its faults for the finishers to accept it 

 with enthusiasm. This has been accomplished by the 

 Mattson Gold Rubber. It is a compact, malleable, 

 odorless gum not too sticky and capable of any degree 

 of softening by the gentle heat radiating from the 

 tool heater. It remains forever plastic, and although 

 it sticks like a miser to the gold, it does not stick to 

 the fingers of the workman. It is put up in neat tin 

 boxes each holding about three ounces. This small 

 amount of gum will easily hold 32 penny-weight of 

 gold or about $30 worth before the olive oil, used in 



the size begins to make it hard to handle. Long before this 

 time, however, it is usually sent to the smelters where the 

 burning of the rubber sets the gold free. [Mattson Rubber Co., 

 No. 26 West Broadway, New York.] 



ORNAMENTAL RUBBER TILING. 



Anything in the line of a locking device for rubber tiling 

 is, at the present time, of interest, and the simpler it is the 

 more it appeals 

 to the practical 

 man. The type 

 shown in the 

 accompanying 

 i 1 1 u s t r a tion 

 consists of two 

 shapes, one like 

 a capital "I," 

 the other an 

 " E " with the 

 middle mark 

 left out, thus C. 

 These, when 

 built together, 

 hold perfectly 



without using the familiar " interlocking " devices. The sepa- 

 rate pieces of rubber need but two dies in the making, and are 

 really short strips rather than blocks. By the use of different 

 colors and combinations a great variety of artistic effects may 

 be produced. Design patent No. 36 558, granted to R. L. Chip- 

 man, September 15, 1903. 



THE CHASE MUFF LAP ROBE. 

 This combination of muff and lap robe is an excellent thing 

 for all who drive, ride in automobiles, or journey by sea or land 

 where a robe or rug is desirable. With the combination one's 

 hands are kept warm and the rug is easily held in place — two 

 boons that are not conferred by the possession of the ordinary 

 robe. In construction the muff is a departure from anything 

 yet made, as it has a rubber and wool padded interlining, mak- 

 ing it both waterproof and windproof, and as warm as a fur 

 muff. In the same way, the robe has a rubber interlining, is 

 absolutely windproof, and in fact, is just as warm as a fur robe 

 but much lighter in weight and not nearly as expensive. Pat- 

 ents have been applied for covering this promising novelty.
