THE EWALD TIRE RETREADER. 



:)rn casings, properly stapled together with the 

 ill give from 1,000 to 3,000 miles of 

 service, is of interest to 

 tire dealers, repair men 

 and tire users generally. 

 The operation is ex- 

 tremely simple. Having 

 two worn tires of the 

 same size, cut the treads 

 from the best one and 

 slip it over the other cas- 

 ing Insert a staple in 

 I he holder and push it 

 ill the way down, then 

 I lace the tire over the 

 machine table, setting the 

 ., iiigc so that the staples 

 will be three-eighths of 

 an inch from the outer 

 casing edge. A forward 

 movement of the hand- 

 lever forces the staple 

 This operation is repeated 



through the casings and clinche 

 around the tire on both sides, setting the staples about one 

 inch apart. A three-quarter-inch reliner strip of gummed fabric 

 is then placed over the staples and the tire is ready for the 

 road. (Romort Manufacturing Co., Oakfield, Wisconsin.
