THE INDIA RUBBER WORLD 



423 



Perkin, Strange and Mathews. Cheap and abundant raw ma- 

 terial is a point of the tirst importance in the production of 

 synthetic rubber. Several raw materials are referred to as 

 possible bases of future synthetic rubber, such as acetylene and 

 •carburet of calcium. 



In the concluding words of the volume : 



"As between the cup and the lip, there is room between the 

 laboratory and the factory for some disappointments and for a 

 good deal of work." 



The book is a valuable contribution to rubber literature, par- 

 ticularly with reference to synthetic rubber. 



NEW TRADE PUBLICATIONS. 



"R 



E.\CI1 1914 H.-\SEBALL" is the title of a catalog which 

 has just been issued by the A. J. Reach Co., of Phila- 

 delphia, enumerating a very complete line of baseball sup- 

 plies suitable for the 1914 season. Five pages of this thirty- 

 two page booklet are devoted to baseballs, no less than 23 

 varieties of which — some with rubber centers, some with rub- 

 ber surrounded cork centers, and one, the "Lively Flyer," 

 made entirely of rubber — are described and illustrated. 

 Twenty pages are occupied by mitts and gloves of styles 

 appropriate for catchers, basemen, fielders, etc.; bats, masks 

 and body protectors occupy two pages each, the final page 

 and inside back cover showing bat and uniform bags, bases, 

 plates of rubber, etc., score cards and shoe plates. It would 

 seem practicable to select from this catalog any article re- 

 quired by any player, the illustrations, descriptions and prices 

 being particularly clear. 



The North British Rubber Co., Limited, Castle Mills, 

 Edinburgh, has just sent this office a most attractive booklet, 

 the 16 pages of which are devoted to description and repro- 

 ductions in colors of various designs in rubber floor tiling 

 as made by this company, also mentioning rubber mats, stair 

 treads, etc. The colored photographs represent tiling as laid 

 in offices of insurance companies, banks, mercantile houses 

 and on decks of steamships, tho its suitability for use in other 

 places — such as hospitals, churches, public offices, libraries, 

 etc. — is apparent. 



The Acme Rubber Manufacturing Co., of Trenton, New Jersey, 

 has distributed among the trade a booklet of 16 pages descrip- 

 tive of Acme Red Letter tires, and containing prices, etc. Every 

 tire put out by this company bears the name of the company, a 

 serial number and the brand "Acme" in large red letters, and 

 tires from which these marks have not been effaced are guaran- 

 teed, the nature of the guarantee being described on page 13 of 

 this booklet. Red letter tires are hand made with wrapped tread 

 and given single cure in open steam, while Acme Red Letter 

 inner tubes are described as being made extra heavy and united 

 by a special process so that slow leaks cannot develop at the 

 splice. These tires are made plain tread, dimple tread — anti skid 

 and Hemisphere tread — anti skid. Schedules of weight and infla- 

 tion and of interchangeable sizes are given, also advice to tire 

 users and telegraphic code. The booklet also contains descrip- 

 tion and price list of Acme inner liners. It has 7 illustrations, 

 including a photograph of the company's plant at Trenton. 



A four-page folder of newspaper size is being sent out by the 

 Firestone Tire & Rubber Co. to its dealers all over the country, 

 and largely in their interest. It contains numerous suggestions 

 which, if properly followed out by the dealers, would probably 

 result in greatly increased sales. The inside pages show proofs 

 of electrotypes in various sizes ready for the dealers' use in their 

 local papers, space being left in each case for the insertion of the 

 dealer's name in type. The last page shows special electrotypes, 

 etchings or halftones, illustrating various types of tires, tubes, 

 repair apparatus, etc. Each folder is accompanied by a postal card 



for use by the dealer in sending in his order for cuts, which are 

 furnished absolutely free and delivered all charges prepaid. 



MOTOR TH1JCKS OF AIISBICA. 



On account of the cniliusiastic reception accorded last year 

 to the first volume of "Motor Trucks of America," the B. F. 

 Goodrich Co., of Akron, has been encouraged to make the issue 

 a yearly one. Volume 2 has accordingly been published and 

 contains a wealth of information about more than ninety motor 

 trucks built in the United States; thus placing full and accurate 

 details at the disposal of prospective buyers. The illustrations 

 are in the highest style of execution, while the specifications 

 include in most cases the Goodrich tires, either as regular or 

 optional equipment. 



With the details given the customer can appreciate how each 

 car looks and what it claims to do. Motor truck buyers require 

 such data about motor transportation as will enable them to 

 select the right truck for their particular service, and thus get 

 the best results from their investment; their aim being to obtain 

 the largest amount of productive time per unit of machinery. 



Comparison of details is the surest way to obtain satisfac- 

 tion and this has been abundantly provided for by "Motor Trucks 

 of America." The Goodrich company, Akron, will be glad to 

 send a copy of the second volume, on receipt of a request to 

 that effect on the letter head of the prospective truck buyer. 



TKUCK STANDAEDS IN CAKD FORM. 



Sets of cards showing standards of commercial vehicles rec- 

 ommended in 1912 by the National Association of Automobile 

 Manufacturers are being mailed to all manufacturers of com- 

 mercial vehicles by the National Automobile Chamber of Com- 

 merce, successor to the above-named association and to the Auto- 

 mobile Hoard of Trade. These seven cards, 8 x 10, are arranged 

 for filing or distribution and include warranties, in form approved 

 December 3, 1913, superseding the motor truck warranty recom- 

 mended by the N. A. A. M., in 1912, which it combines with the 

 standard passenger car warranty adopted in 1910. The tables are 

 accompanied by charts of curves and by half-tone engravings 

 illustrating the new lithographed standard warranty. 



The subjects of the cards are as follows: 



Standard Warranty, Standard Speed Rating, Standard Body 

 Weight .Allowance, Overload .'Allowance Resolution, Standard 

 Caution Plate, Standard Frame Widths, and Lengths and Stand- 

 ard Demonstration Charges. 



To encourage the adoption of these standards, the National 

 Automobile Chamber of Commerce is sending sets of the cards 

 to all companies on its list of active manufacturers of com- 

 mercial vehicles. 



Requests from those makers who have not received cards 

 should be addressed to Secretary, Commercial Vehicle Commit- 

 tee, National Automobile Chamber of Commerce, 7 East Forty- 

 second street. New York City. 



PROTECTION FOR THE EAR AGAINST NOISES. 



On page 581 of the August, 1913, number of The India Rubber 

 World, mention was made of an invention composed of a 



celluloid tube with rubber discs 

 to prevent impairment of the 

 sense of hearing through shock 

 from gunfire or other loud 

 noises. No adequate illustration 

 of the device being at that time 

 available, and believing that such 

 an illustration might be of in- 

 terest to our readers, we repro- 

 duce herewith a drawing which 

 shows the protector in use.
