THE INDIA RUBBER WORLD 



[February 1. 1913. 



The Thcrmoid Rubber Co. showed a lull line of brake lining, 

 bumpers and hose, red inner tubes bearing the trade name 

 "Merit." Their "Thcrmoid dc Luxe" tire is the company's 

 leader. They also manufacture the "Nassau" tire. 



The Miller Rubber Co. has developed a new tread. It consists 

 of angle-shaped depressions arranged in two rows, one on each 

 side of the centre of the tread. They are manufactured by the 

 one-cure wrapped tread process. 



The United States Tire Co. showed the "G. & J.," Morgan 

 & Wright, Continental, and Hartford tires. The tread with 

 two chains running around the tire was on the stand, and the 

 "Nobby" tread was seen on an extra large tire designed for 

 truck use — 38 x 8 — easily the largest tire there. This company 

 also showed a new red inner tube. 



The Republic Rubber Co. makes the "Staggard Tread," which 

 has a series of finger-like projections running around the tire. 

 There are six rows of these so set that the space between two 

 ■of these come opposite centres of the adjoining row. 



The Empire Rubber & Tire Co. showed a new line of red tires 

 in smooth and non-skid treads. They claim that this wears better 

 and heats less than grey tires. 



The Diamond Rubber Co. exhibited the "Squee-Gee" tread as 

 their safety ; and the "Diamond Silvertown Cord" tires, the 

 making of which is described in the first part of this article. 

 The "Squee-Gee" tread consists of a series of five finger-like 

 projections joined together through their centers by a strip of 

 rubber running across the tread. This design repeats itself 

 around the tire. These tires are made of vitalized rubber. 



The Goodyear Tire & Rubber Co. showed tires with straight 

 sides, and also oversized tires. The "No-rim cut" features mark 

 this line. The anti-skid tread is made up of triangular shaped 

 studs. These tires are made bv tbo double-cure process. 



The B. F. Goodi ch Co. displayed a large line of tires, among 

 which were the "Goodrich Safety Tread" and "Goodrich Cord 

 Tires" for electrics. In the latter cord replaces fabric. These are 

 both new developments of this company. They also showed a 

 new plug for mending punctures, resembling a collar button in 

 appearance and method of insertion. This instantly closes a 

 puncture. They also had a self-vulcanizing patch. 



The Seamless Rubber Co. had a straight-side or clincher tire. 

 They are made plain or safety tread. They have a series of cuts 

 at each side of the centre of the tread, resembling a scaling 

 ladder. The seamless tubes are of red and of grey rubber and 

 are built without a seam. 



The Firestone Tire & Rubber Co. had a new red inner tube. 

 Their line of tires is marked "Non-Skid" diagonally across the 

 tread. The abrupt angles and hollows of the letters grip the 

 road and prevent slipping. Firestone cushion tires for electric 

 pleasure cars have double tread and internal cavities. 



The Portage Rubber Co. makes a heavy pneumatic tire of 

 four and five-inch sizes, having from eight to ten plies of fabric. 

 Durability and not speed is claimed of this style. Its non-skid 

 tread has many edges and angles which grip the road in all 

 directions. This is known as the "Daisy Tread." 



The "Brown Scientific Non-deflating" tube, made by the 

 Voorhees Rubber Manufacturing Co., is made in some respects 

 similar to a casing. It is made upon a mandrel, the outer, or 

 tread, half being of double thickness. On the inner side is 

 placed a strip of extremely high-grade non-elastic fiber. It is 

 then vulcanized, blown off the mandrel and turned inside out, thus 

 placing the rubber inside, causing the rubber to compress suffi- 

 ciently to effectually close any puncture. 



The Double-Fabric Tire Co. makes the "Interlock" inner tire, 

 which is made to be placed between the inner tube and the shoe. 

 It consists of a substantial casing-like structure, which has a 

 thicker portion where the interlock comes in contact with the 



shoe, and at the beads has two wide over-lapping flaps which 

 serve to lock the device when the tube is inflated. 



The Walpole Rubber Co. guarantees its tire against stone 

 bruises and defects in manufacture. The construction, which is 

 tlie basis for the stone bruise guarantee, consists of placing a 

 gum breaker strip between the fabric and the tread one-eighth 

 of an inch thick, tapering it down at the bead. 



The Federal Rubber Manufacturing Co. makes the "Rugged- 

 Tread." This has three rows of strong studs set equidistant upon 

 the body of the tire. 



The Continental Rubber Works, makers of the "Continental- 

 Erie," "Liberty" and "Tribune" brand of tires, had an exhibit of 

 these tires in plain and anti-skid treads, fitted for the Q. D. 

 Clincher, and straight-side rims. Their tires are noted for their 

 wearing capacity. 



The Essex Rubber Co. showed a line of automobile and tire 

 sundries such as blowout patches, inner sleeves, hook-on and 

 lace outer boots, "Perfection" rubber goggles, red rubber tubing, 

 radiator hose, gas-engine packing, brake lining and rubber spring 

 bumpers. I 



The L. J. Mutty Co. had a line of "Numotor" fabrics in 

 single texture for automobile seat covers, and also double te:4- 

 ture with Para rubber interlining for tops. These fabrics are 

 made of cotton yarn, dyed in the fiber with a special dye, 

 "Indanthrene" which will not fade. The single cloth comes 54 

 inches wide, and the double 60 inches wide, so as to eliminate the 

 center seam in tops. It comes in all colors and is guaranteejd 

 absolutely waterproof. 



The Standard Woven Fabric Co. showed the "Multibestos" 

 Brake lining. This comes in all sizes and is interwoven with 

 copper wire. Oils do not injure it, and it will not burn. 



A. Schrader's Son, Inc., had their Universal tire gauge on ex- 

 hibition, also the pencil type, which is very small, only 2,'/2 inches 

 long. Both of the gauges remain fixed so that they can be re- 

 moved from the valve stem for easy reading. 



The Overman Tire Co. exhibited a cushion tire of generous 

 proportion and of new design. It is based on the flow of rubber. 

 Such a tire requires a special rim to which the tire is bolted in 

 the center near the base. There is a triangular cavity extending 

 around the tire. This permits a flow of rubber inward. The 

 tread is cut with alternating wedge-shaped indentations around 

 the edge, which prevents skidding and allows the rubber to 

 give under pressure. 



The Racine Rubber Co. makes a "Trusty Tread," composed 

 of three rows of elongated studs; those in the centre being set 

 straight on the tread, the outer ones arranged irregularly ; so 

 that the breaks between studs do not come opposite each other. 

 The Swinehart Tire & Rubber Co. makes the "Keaton De- 

 pression" tread. These are kite-shaped depressions grooved in 

 centre, and act like a sharp skate on the ice, makmg it impossible 

 to slide sidewise. They also make the "Electrical Cellular" tire, 

 which consists of a series of deep holes in a solid tire, forming 

 a suction upon the road bed. 



The entire Marathon line was new, for the Marathon Tire 

 and Rubber Co. is a late entry into the tire field. The "Angle" 

 tread is its most marked feature, and designed for non-skidding 

 purposes; plain treads are also furnished. The company's inner 

 tube is of red rubber, for which much is claimed by the tire- 

 makers as an inner tube material. 



.•\ puncture-proof tire made by the Lee Tire and Rubber Co. 

 was mounted on a bed of spikes, weighted with over half a 

 ton upon the wheel. This tire has several layers of small round 

 metal disks imbedded in the tread and interlapping each other 

 with a thickness of rubber between. This is to prevent sharp 

 objects from entering the tire. They also make the "Zig-Zag" 

 tread, which grips the road with all the tenacity of chains. 

 When the middle wears down the sides prevent the car from 

 skidding.
