ROWLEYS TIRE BUILDING MACHINE. 



The illustration shows in a general way a portion of the 

 tire-building machine invented by Robert Rowley of New 

 York (Pat. April 25, 1911, Xo. 990,392). The mechanism 



Rowley's Tire Huilding Machine. 



is designed briefly to lay a strip of rubber frictioned fabric 

 back and forth from edge to edge of an open bellied tire 

 shoe. It is also arranged to build a single tube type which 

 may afterward be cut open on the inner circumference and 

 thus form the usual open shoe. 



CENSUS DISREGARD OF RUBBER STATISTICS. 



I.\ VIEW of the extent to which rubber enters into our na- 

 * tional manufactures, it is a matter of regret that its results 

 did not form the subject of a special bulletin for the census of 

 1905, nor is there any assurance that any such special reports 

 will be issued for the census of 1910, the results of which are 

 now being compiled. In value, rubber, with 107 millions of dol- 

 lars for last year, formed a close second to hides and skins, the 

 imports of which in 1910 reached about 114 millions of dollars. 

 With regard to production, as the results for the separate 

 branches of the rubber industry are shown in the census returns 

 for 1905 under different heads, it is necessary to group them 

 in order to arrive at the facts of the case. The figures for 1905 

 include among principal items of production : 



Rubber boots and shoes $70,065,296 



Rubber and elastic goods 62,905,909 



Rubber belting and hose 14,954,186 



.Apart from the electrical uses of rubber, it is the basis of 

 various other industries, so that it may reasonably be estimated 

 to have represented in 1905 about 200 millions of dollars of our 

 national manufactured output. 



Since 1905 the business has expanded enormously. It would 

 therefore be most interesting if the census would give us figures 

 including the production of 



Automobile and Cycle Tires. 



Solid Tires. 



Druggists' Rubber Sundries. -■ 



Hard Rubber. 



Reclaimed Rubber. 



Cements. 



Carriage Cloth, Surface Clothing, Mackintoshes and 

 Rubber Surfaced Goods in analogous lines. 



Dental and Stamp Rubber. 



Whatever may have been the situation in 1905, special interest 

 attaches to the changes which have since occurred. Pending 

 the compilation of the United States Census returns, those of the 

 separate States, issued by the various State Statistical and Fac- 

 tory Inspection Bureaus, contain a good deal of pertinent in- 

 formation. Among the first of these returns is the report of 

 the New Jersey Bureau of Statistics, which, to a great extent, 

 anticipates the United States Census figures. By comparing the 

 latest return, for 1909, with those for 1908 and 1904, as has been 

 attempted in the subjoined table, the growth is seen of the New 

 Jersey rubber production between 1904 and 1909, from 17 to 

 30 millions of dollars. This augurs well for the genera! pros- 

 perity of the industry.
