NEW GOODS AND SPECIALTIES IN RUBBER. 



"imperial" rubber vehicle tire. 



THE distinctive feature of the construction of this solid 

 rubber vehicle tire is that it provides a greater amount 

 of rubber between the wires and the channel than 

 has been true of tires in this class hitherto. The con- 

 stant compression and strain on many tires in the market 

 causes them, after short service, to become cut by the wires 

 and loosened from the wheels. By referring to the illustrations 

 on this page it will be noticed that the holes for the wires 



are above the angle of the channel and tire. This gives an 

 extra thickness of rubber between the holes and the base of 

 the tire, whereby increased service from the rubber is gained. 

 Besides large wires are used in connection with the " Imperial " 

 tires, which are less liable to cut the rubber. The fabric in 

 these tires is heavily coated with rubber, which prevents it 

 from becoming rusted and rotted through the action of water 

 and moisture. Sections are shown here of iji inch and i)s 

 inch tires ; they are made in sizes from ^ inch up. [Boston

LARGE RUBBER HOSE. 



The illustration herewith has been made from a photograph 



of a section of rubber suction hose manufactured by the Bowers 



Rubber Co. (San Francisco, California.) The measurements 



have not been stated, but the position within the hose of a full 



grown man indicates the diameter very fairly. The Bowers 

 Rubber Co. were incorporated November, 1890, to continue 

 the busiuess of manufacturing rubber goods, commenced in 

 San Francisco in 1888 by W. F. Bowers & Co. The firm make 

 a specialty of the lines of rubber goods in demand in the mining 

 districts. 



THE GAME OF "PING PONG." 

 The British correspondent of The India Rubber World, 

 in his notes this month, refers to " ping pong " as having be- 

 come so popular as to have enhanced the consumption of cellu- 

 loid to an important extent. The game likewise has gained 

 much vogue in Germany. It is a house game, and is known 

 also as room lawn tennis, or table lawn tennis, to say nothing 

 of another name — " Gossima." The game appears to have be- 

 come little known in the United States as yet, although it may 

 be seen in the windows of A. G. Spalding & Brothers, the 

 sporting goods dealers, 



FRENCH AUTOMOBILE HORN. 

 This automobile horn, which is called a " squacker " in 

 France, is made in three sizes— small, medium, and large — 

 which retail in this country at $6, $7, and $10, respectively. 



They are imported and carried in stock in this country by 

 Charles E. Miller, dealer in automobile material, Nos. 97-101 

 Reade street, New York, who has favored us with the illustra- 

 tion herewith. 



VENN'S PATENT SHOE MARKER. 

 The illustrations herewith will clearly show the improvement 

 that has been made by Frank Venn (Maiden, Massachusetts), 



in his new patent marker, for 

 marking rubber boots and 

 shoes, which is now being used 

 with success in many factories. 

 The old style shoe marker 

 patented by Mr. Venn was 

 illustrated and described in 

 The India Rubiser World, 

 August 10, 1897. As will be 



THE OLD STYLE. 



THE NEW STYLE. 



seen by comparison of the two cuts given here, the new 

 or perfected marker has a handle all of one piece. It is de- 

 signed especially for use by girls, the new marker being only 

 two-thirds as heavy as the old one, though just as strong and 

 durable. Many years of experience showed that the machine 

 Mr. Venn had been making was not perfectly adapted for mark- 

 ing shoes ofT the last, which is now done by many manufactur- 

 ers, it being too heavy for the girls to use. He has, therefore, 

 reduced very materially the weight of his new marker, from 

 about 24 ounces to 16 ounces. He has found that the letter F
