New Machines and Appliances. 



VACUUM-DRYING, IMPREGNATING, AND SOLVENT RECOVERY 

 APPARATUS. 



THIS APPARATUS has been specially designed for impregnating 

 tire fabrics, belting and hose duck, and other fabrics; 

 drying after impregnating, and recovery of the volatile 

 solvent employed. 



The complete operation takes place under vacuum. The 

 material is first dried by passing it from the top roller to the 

 bottom roller between the heating tables. The solvent is then 

 admitted to the chamber and thoroughly impregnates the ma- 

 terial owing to the air having been entirely expelled. The 

 material is then rewound on to the top roller, passing between 

 rollers to squeeze out surplus solvent, and afterwards between 

 the heating tables to thoroughly dry it. 



The vapor from the drying chamber is drawn through a 



Machine for Vacucm-Drv 



Recovery, 



the 



multitubular condenser by means of a vacuum pump, 

 condensed solvent is collected in the receiver. 



Details of construction vary according to the materials to be 

 treated, and the solvent used. (Francis Shaw & Co., Limited, 

 Bradford, Manchester, England.) 



OIL-WIPER FOR SELF-OILING BEARINGS. 



The use of an efficient oil-wiper on bearings, particularly 

 heavy ones, results in a saving of oil, labor and machinery 

 repairs. Such devices are well adapted lo rubber mill practice. 



The wiper ot 

 novel construc- 

 t i o n here 

 shown consists 

 of a tempered 

 slcel spring 

 with a triangu- 

 Inr-shaped 

 ill. ce of Babbitt 

 Dictal mounted 

 nil the end. 

 This piece of 

 Babbitt metal is 

 shaped to the 

 shaft and wipes 

 the shaft clean 

 and returns the 

 oil to the reser- 

 voir of the 

 bearing. The 

 spring is fas- 

 tened to a convenient point in the groove at the end of the 

 bearing or to the housing at the end of the bearing. There is 



Oil-Wiper for Bearings. 



These wipers are equally useful for all self-oiling bearings, 

 whether plain, roller or ball. It is said that on a test run 

 of four months on ten bearings, each transmitting 250 horse- 

 power, one gallon of oil was required for replacement on all 

 ten bearings. (Industrial Products Co., 1024 Penobscot Build- 

 ing, Detroit, Michigan.) 



BEAD-MAKING MACHINE. 



The growing popularity of 

 straight-side tires has stimulated 

 the invention of labor-saving ma- 

 chinery to meet the tire manu- 

 facturers' requirements. The in- 

 e.xtensible beads used on all 

 straight-side tires are built up on 

 an annular wire core, and the ma- 

 chine shown in the accompanying 

 illustration is especially designed 

 tor the purpose of making this 

 bead-core. 



The wire is fed from a stock- 

 reel to an e.xpansion-head, where- 

 by any size of bead from 31 by 

 4 inches to 38 by S^'j inches may 

 be formed. The machine is Wire-Bead Machine. 



equipped with a direct motor- 

 drive and starting switch. (Gillette Rubber Co., Eau Claire, 

 Wisconsin.) 



iper placed at each end of the bearing. 



THE W-S-M HYDRAULIC RIMMING-PRESS. 



According to the old method used in the manufacture of 

 cord tires, the air-bag rings were drawn together by hand- 

 operated bohs that held them together — a very tedious process. 



The de- 

 mand for a 

 small but 

 simple press 

 for doing 

 this work 

 has resulted 

 in the ma- 

 chine here 

 i 1 1 u strated. 

 By using 

 this press 

 the rings 

 are quickly 

 brought to- 

 gether ready 

 to receive 

 the bolts, no 

 me c hanical 

 know ledge 

 being ne- 

 cessary. . 



The cyl- 

 inder, ram, 

 and platens 

 are of heavy semi-steel and the cylinder and base are cast in 

 one piece. The cylinder is outside packed with a U-leather 

 ring-packing having a flax core and held in place by a gland 

 which can be easily removed. 



The ram cap or lower platen and the upper platen are spider- 

 shaped to enable the operator to tighten up the bolts on the 

 rings easily after they have been forced together. The upper
