NEW GOODRICH SAFETY TREAD TIRE. 



RAISED tread fiirination in any style does not of itself con- 

 stitute a non-skid tire. It is the arrangement of it which 

 offers resistance to any sHpping or skidding movement. In 

 the case of the traction engine, the cross-bars or strips at- 

 tached to the rim of the 

 wheel bite into the road, 

 giving the necessary hold 

 against slipping, thus al- 

 lowing the bulky engine 

 to be propelled up and 

 down hill, and over all 

 kinds of roadway. 



The application of this 

 principle to the tread of 

 an automobile tire has 

 been engaging the at- 

 tention of the B. F. 

 Goodrich Co., and the 

 apparent diiliculty in the 

 matter has been overcome by means of a series of longitudinal 

 bars, broken into cross sections and strengthened by the cross- 

 bars. In this way there is in reality a double series of raised 

 projections, with the cross-bars holding against forward slipping 

 and the longitudinal bars gripping the pavement and lessening 

 the possibility of side slipping. 



The double set of bars is distributed so as to prevent any 

 punching in at any point on the fabric construction. In this 

 way the cross-bar principle of traction wheels is adapted to 

 automobile tire tread construction, being modified to meet rub- 

 ber tire conditions. [B. F. Goodrich Co., .Akron. Ohio.] 



scription. The importance of these preventives in cases where 

 the coating of the stomach of the patient had been injured was 

 particularly dealt with. 



"STEEREASE." 



For the prevention of slipping through the hands, it has been 

 customary to wrap motor steering wheels with twine, rope, tap 

 etc. .Apart from the fact that such 

 a wrapping is apt to chafe the hands, 

 its efficacy for the purpose intended 

 has hecn questioned. 



With the object of meeting 'this 

 difficulty a new device. "Steerease," 

 has been introduced. This is manu- 

 factured from a fine quality of rubber, 

 specially molded, and constructed to fit the steering wheel of the 

 various motor cars and trucks. Being slightly corrugated, it pre- 

 vents any slipping of the hands in wet 

 weather, while there is no bunching, 

 caused by the slipping of the cover 

 upon the wheel. 



"Steerease" is easily applied. -After 

 thorough cleaning and the consequent 

 removal of all moisture and grease, 

 it is stretched over the wheel, the 

 edges being made to fit closely to- 

 gether. These are turned back and 

 the cement applied ; being allowed to 

 spread as much as possible. The wheel is firmly wrapped with 

 tape and allowed to stand overnight, being then unwrapped.

 gloves afforded greater antiseptic protection than any other de- 



THE ESSEX BUMPERS. 



Among the prominent features of the Essex Rubber Co.'s 

 line of automobile accessories are their very elastic and pliable 

 rubber spring bumpers. These are made from high-grade 

 stock, and retain their elasticity without becoming hard from 

 old age. With the object of conforming to different kinds 



of springs, they are made in vari- 

 ous shapes and sizes ; the oblong be- 

 ing in three sizes, from d'/z to &'/i 

 inches in length, 1^ to l-)4 in. width, 

 and 3 to 4 in height. The round 

 bumpers (illustrated herewith) are 

 likewise made in three sizes from Ij/j 

 to 2 inches in width, and from 3% 

 to 3f4 in. diameter. One special ad- 

 vantage of the Esse.x Bumpers is that 

 they will at certain times prevent the 

 springs from breaking, when sub- 

 jected to a sudden jolt. 



Seeing the important functions of 

 the spring bufifer, the value of its 

 This consideration is specially met 

 by the Esse.x Rubber Go's products of this class, which are the 

 results of close study of existing requirements.

 popular among many users of automobiles. It is made of fine 

 duck and high grade rubber. [Essex Rubber Co., Inc., Tren-

ANDERSON NEVERSLIP CUSHION HEEL. 



The Anderson Patent Neverslip double cushion heel is said to 

 be a triumph in rubber heel manufacture. Among its other 



features, claim is made 

 that it is self-leveling 

 and arch-supporting. It 

 is further claimed that it 

 is unusually resilient and 

 will absolutely prevent 

 slipping. The patentee.

ME. EGGERS INVENTS A NEW MOLD. 



.A new type of mold adapted for the manufacture of both 

 hard and soft rubber specialties, which produces excellent results 

 and costs less than the old kind, is now being made under his 

 own patents by William Eggers, the well-known rubber machinist 

 of Brooklyn, New York. The weight of the new molds is much 

 less, consequently they are more easily handled ; and because of 

 the thinner material, they are more susceptible to heat and more 

 uniform in vulcanization. The molds are so constructed that 

 they cannot warp and are said not to be adversely affected by 

 heat. The metal of which thej' are made, while less expensive 

 than the material formerly used, takes a very high polish, giving 

 the rubber product a fine finish. These molds are being used 

 by prominent manufacturers, who state that they have used, 

 them with much success.
