ALLEN 10-INCH TUBING MACHINE. 



THE steady growth and expansion of the rubber industry is 

 reflected in the insistent demand for larger capacity ma- 

 chines used in the mak-ing of rubber goods. That the tire 

 business is no exception to this rule is shown in the illustration 

 of a large and powerful tubing machine, designed for making 

 solid truck tires. 



The machine is of extra heavy design. The feed box meas- 

 ures 9 by 10 inches, and is capable of handling large quantities 

 of stock without forcing the feed. The length of the cylinder 

 has been increased to allow greater bearing surface for the 

 worm, thereby increasing the compression and giving greater 

 density to the stock. The stock worm is made from a solid 

 forging, bored for water circulation, the delivery end being 

 counter-bored, thereby reducing the metal at this point so the 

 circulating water will more readily cool the worm. 



The stock worm spur gear has a 12-inch face and a bronze 

 bushed hub bearing directly on the thrust block. This is 22 

 inches in diameter at this point, resulting in a large and rigid 

 bearing that greatly relieves the worm from the usual side 

 thrust strain. The reduction gears are double helical cut, with 

 semi-steel gear and forged steel pinion. The outboard bearing 

 pedestal is en bloc, the three bearings being cast in one piece 

 with large oil reservoirs and self-oiling devices. All gears are 

 entirely protected by heavy steel guards. The bed plate is 



continuous and provides space for the motor, which is supplied 

 by the purchaser. A 60 h.p. variable speed D. C. motor is con- 

 sidered good practice. [Allen Machine Co., Erie, Pennsylvania.] 



The double drum rolling mechanism at the back of the ma- 

 chine has guide stands with quick adjustments to take any gudg- 

 coned roller within the machine's capacity. The cloth may be 

 threaded direct from the stamping table tci the rnll. or may first 



pass under both drums, around and outside of the outef drum 

 to the roller. The latter threading gives the stronger drive and 

 a harder roll. Those who market their fabrics wound in the 

 open width on any kind of a roll or tube, can adapt this as a 

 tinal packaging machine. 



The following are the specifications : Widest cloth capacity, 

 66^ inches ; driving pulley diameter, 10 inches ; revolutions per 

 minute, 60; belt width, two inches; length over all (right and 

 left), 98 inches; depth (front and back), SO inches; height, 68 

 inches; shipping weight, 1,5CK3 pounds. [Parks & Woolson Ma- 

 chine Co., Springfield, \'ermont.] 



MACHINE FOE SLITTING AND REWINDING RUBBER. 



Cameron's slitting and rewinding machine can be used on all 

 sorts of rubber goods such as sheet rubber, coated fabric, canvas 

 belting, insulation, etc. 



The slitting wheel, which presses rather than cuts through the 

 material, is a disk having a V-shaped edge, blunt and mounted 



The manufacturers of tire fabrics, proofed fabrics and car- 

 riage cloth will be interested in the following illustrated descrip- 

 tion of a machine that has recently been adapted to the rubber 

 industry. 



The Kaumagraph machine takes the cloth from the roll or 

 loose fold, trade-marks it, measures it and delivers the goods 

 in the roll. Moreover, the faliric can be inspected at the same 

 time. 



The trade-marking attachment is mounted above at the right 

 hand end of the machine and stamps on the upper surface of 

 the cloth, so that the impressions may be inspected immediately 

 after being struck and without stopping the cloth. 



The machine is fitted with a hand wheel and screw to adjust 

 the attachment for different widths of goods. The cloth will, 

 therefore, always run in the center of the machine. The adjust- 

 ment is so quick that various widths of pieces may follow each 

 other without inconvenience. The trade-marks may be spaced 

 at any distance apart and convenient means are provided to place 

 a trade-mark close up to the ends of each piece. 





on a ball-bearing center, pressed against a highly polished steel 

 cylinder. \'ery little attention is required to keep it in good 

 working order. The fabric passes between the cutter roll and
