New Machinery and Appliances. 



TixG Tire — Beginning of Stroke. 



THE W-S-M HYDRAULIC SOLID-TIRE PRESS. 



ANECESSARY part of the equipment of truck service sta- 

 tions and garages is a solid-tire applj-ing press. Speed, 

 simplicity and strength should be the prominent char- 

 aclerisiics of this machine that must be always ready and ef- 

 ficient and require but 

 little meclianical 

 knowledge in the op- 

 eration of mounting 

 and demounting tires. 

 Such specifications 

 are embodied in the 

 press shown in the 

 accompanying illus- 

 tration. It operates 

 by hydraulic pressure 

 and is built in two 

 sizes with 150 and 

 200-ton pressure rat- 

 ings. The frame con- 

 struction and strength 

 of the fittings are 

 amply able to take 

 care of the occa- 

 sional serious over- 

 loads that are de 

 manded in service. 



To mount a tire 

 the ram is lowered 

 the wheel is placed 

 on lower platen, with 1^ 

 the tire in position M 

 above it. The belt is 

 thrown onto tiyht pulley, and the control valve closed. 



To demount the tire a ring is placed on the lower platen, 

 just large enough to clear wheel, which is placed upon it. A 

 second ring, or a set of blocks as is sometimes used, is placed 

 on the circumference of tire. The control valve is then closed, 

 and the tire pressed down off of wheel. (The Wellman-Seaver- 

 Morgan Co., Akron, Ohio.) 



TWO-DIP SPREADER FOR CORD FABRIC. 



This machine is particularly designed for coating cord fabric, 



providing two coats with a short drying operation between the 



two immersions and a somewhat longer and more thorough 



process after the second coat. 



The let-ofif for handling the fabric is carried on a separate 

 stand on the feed end of the machine, delivering the fabric to 

 the machine under a light tension. The fabric passes through 

 the first tank and receives a heavy coat of cement, the excess 

 being removed by a scraper bar, and the pressure being regulated 

 by a spring. The fabric is then carried over two vertical steam- 

 coils and partially dried before being delivered to the second 

 tank, at which point it is given an additional coat. It is then 

 thoroughly dried over a bank of four vertical steam-coils and 

 delivered to an external wind-up stand which also carries a fric- 

 tion let-off for the liner. 



The fabric in passing through the machine is driven by six 

 rolls carried on the bottom framework on plain bearings and 

 driven by an endless belt. Idler rolls are provided over each 

 drying section and are mounted on ball bearings, the first four 

 rolls being of the spreader type, insuring a smooth finish. 



Drying coils, tanks, driving and idler rolls are all mounted on 

 an angle-iron frame which is rigidly braced and supported. 



This framework is enclosed except for a short distance above 

 the floor line by a sheet-metal cover, the driving side of which 

 consists of removable doors. The side section includes a con- 



D Dr\ER 



nection for an exhaust fan to assist in removing the vapor. 

 Due to the inflammable nature of the cement and vapors, it is 

 usual to provide a separate building isolated from the main 

 plant. For this reason the machine has been designed for 

 countershaft drive so that the cement churns and exhaust fan 

 may be driven from the same motor. (The Turner, Vaughn 

 & Taylor Co., Cuyahoga Falls, Ohio.) 



THE LARGEST TUBING MACHINE. 



Tubing machines are invalua 



making a great variety 



of rubber products that range from the smallest rod to the 

 largest solid tire. That the mechanical development of these 

 machines has kept pace with the manufacturing demands is 

 shown by the accompanying illustration of the largest tubing 

 machine. It is interesting to compare tliis 1918 product with the 



original Kiel tubing machine, built in 1876, and shown elsewhere 

 in this issue. 



The Royle perfected tubing machine was built for making 

 solid tires and has a cylinder bore of 9 inches. The die limits 

 arc 3 to 6 inches. Extra large dies of 8^ inches may be used. 

 The machine weighs 18,000 pounds and occupies a floor space
