p,ng the inturned edge of the toe-strip. The last is then placed on 

 the conveyor and the rag sole, the inner sole and the inturned edge 

 of the toe-strip are rolled down together by the mechanism C. The 

 last is then removed from the conveyor and the counter, heel- 

 piece vamp, quarter and outer filler or sole piece are applied, the 

 last replaced on the conveyor and the parts rolled down by a 

 mechanism not shown. The toe and heel fo.xing are then applied 



tion from the coil in the upper part of the evaporating chamber. 

 Thus a smaller volume of circul::ted air effects the same amount 

 of evaporation and a higher concentration of evaporated solvent 

 is reached, as well as more uniform and rapid drying, without 

 risk of overheating. The current of air carrying a large per- 

 centage of evaporated solvent, is now cooled to the saturation 

 point by contact with the cooHng coils. The mixed air and sol- 

 vent vapors thereupon acquire their greatest density, and fall 



and rolled bv a mechanism similar to C, when the outer sole is 

 applied and the edges rolled into close contact with the foxings, by 

 a mechanism not shown, the final set or rollers D completing 

 the operation. [Myron H. Clark, Maiden, Massachusetts, assignor

KEEMERS TIRE BTJILDING MACHINE. 



The principal object of this invention is to provide a tire 

 shoe making machine that will shape or stretch the longitudinal, 

 median portions of the fabric without stretching the edges in a 



corresponding manner. 



The following briefly 

 describes the operation 

 of the machine shown 

 herewith in side eleva- 

 tion. 



The rolls of frictioned 

 fabric are placed upon 



^ the four fabric holders, 



A. and the strips drawn off by feeding them over the liner reels 

 Bin such manner that the liners are rolled up on the reels. 



From the fabric holders, the frictioned fabric passes to a 

 tension mechanism C, which serves to place it under suitable 

 tension or stretching action. The rubberized fabric then passes 

 over shaping rollers D that stretch the longitudinal median por- 

 tions of the fabric, without correspondingly stretching the edges. 

 The shaping or stretching rollers are yieldingly mounted in 

 any suitable manner, and a registering dial £ indicates or 

 registers the tension under which the fabric is placed by the 



stretching devices. . ■ . ..i. 



The fabric then passes to the rotary core F, upon which the 



carcass is built up. The reference letter G indicates the tread 



forming and spinning mechanism by means of which the tread 



is formed and the sheets of fabric are stretched into position, 



and H indicates the bead setting mechanism. 

 The machine is provided with a change-speed mechanism, and 



is driven by an electric motor shown at /. [Franklin W. 



Kremer, Carlstadt, New Jersey. United States patent No.

THE BAKER SOLVENT RECOVERY APPARATUS. 



The illustration is a vertical transverse section of this invention 

 applicable to the recovery of solvents from rubber-coated fabrics. 



In operation the coated fabric is constantly moved through the 

 apparatus ; the air contained therein is first heated by the reheat- 

 ing coils thereby decreasing its density, and increasing tts 

 evaporating capacity. The heated air is then conducted over 

 the coated surface which is subjected to the heat radiated from 

 the heating coils. The heat lost by the coated fabric and the air 

 in contact with it, due to the latent heat, is made good by radia- 



downwardly through the vertical passageway until the condenser 

 is reached. The available part of the solvent is then condensed 

 and removed through the discharge pipe. A portion of the solvent 

 having been separated from the current of air, the latter is again 

 conducted upwardly into contact with the heating coils, thereby 

 decreasing the specific gravity and causing it to again circulate in 

 contact with the coating to be dried. [Theodore Baker, assignor
