ROLL ADJUSTMENT INDICATOR FOR MILLS. 



Imperfect roll adju.stment of washers, mixers and warming 

 mills is very often the cause of trouble in the mill room. If the 

 rolls are not parallel and spaced a definite distance apart, the 

 result will be 

 poor batching 

 and often seri- 

 ous damage to 

 the machine. 

 The present in- 

 V e n t i o n pro- 

 vides a very 

 simple means 

 for preventing 

 these difficul- 

 ties. As shown 

 in the drawing, 



this consists of collars A mounted on each adjusting screw and 

 formed of two halves detachably secured together by a screw B. 

 The periphery of each collar is provided with spaced circular 

 lines scored around the collar, that register with pointers C. 

 attached to each mill frame. The rolls are first brought into 

 contact with each other and the collars then adjusted longitud- 

 inally so that the outer faces D are flush with the ends of the 

 pointers. The adjusting screws are then backed out sufficiently 

 from the mill frames to provide the necessary space between 

 the rolls. This movement causes the circular scale marks on 

 the collars to become visible beyond the pointers and indicate 

 the space between the rolls. [George E. Nettleton, assignor 

 to The Hartford Rubber Works Co., both of Hartford, Con- 

 necticut. United States patent No. 1,206,894.] 



STORAGE BATTERY JAR MOLDING MACHINE. 



This machine is designed for making battery jars or similar 

 articles by folding sheets of rubber stock around a suitable core. 

 The drawing is a sectional detail through the center of tlie 

 machine show- 

 ing the princi- 

 pal parts. These 

 are supported 

 on the table A 

 and comprise a 

 front presser 

 plate 5; a core 

 C ; a rear 

 presser plate 

 D; two vertical 

 folding rollers, 

 one of which 

 is shown at E: 

 two side presser 

 plates, one being shown at F ; and a top presser plate G. 



'Hie operation is briefly as follows : A sheet of rubber H , 

 having on one side a thin sheet of tin, is placed in the opening 

 between the vertical folding rollers, while another sheet is 

 placed on top of the core to form the bottom of the jar. The 

 hand wheel / is then operated, moving the front plate and core 

 forward between the rollers that fold the sheet around the sides 

 of the core, which is forced against the back presser plate. The 

 ends of -the rubber sheet are folded around the front of the core 

 by an alternate right and left movement of a hand lever con- 

 trolling the transverse movement of the folding rollers. By 



means of the hand wheel, the front and back presser plates, with 

 the core and partly finished jar, are moved still further for- 

 ward until directly under the top presser plate, when the move- 

 ment is arrested by stop /. Foot levers, not shown, are now 

 operated together with the cam lever A' to force the front plate 

 forward, the side plates inward and the top plate downward, 

 thereby molding the jar. The core and jar are subsequently 

 removed from the machine for vulcanizing. [William H. 

 Weitling, College Point. New York, assignor to American 

 Hard Rubber Co., New York Citv. United States patent No. 

 1,205,940.] 



M-'SCHINE FOR Wrapping Hose. Strips of frictioned fabric are 

 spirally wrapped under tension around hose or similar articles 

 without using a stiffening core or mandrel or distorting the 

 article being wrapped. [Henry Z. Cobb, Winchester, Massachu- 

 setts, assignor to Revere Rubber Co., a corporation of Rhode 

 Island. United States patent No. 1.204,342.] 



Inner Tube Rag Wrapping Machine. This is really a double 

 lathe with parallel centers. The pole and uncured tube are 

 placed in the back lathe, and the pole with the spirally wound 

 fabric strip is placed in the front lathe. The strip is spirally 

 delivered from one pole to the other by revolving both poles in 

 the same direction. After curing, the strip is unwound from 

 one pole and wound up on the other in the same machine. [John 

 A. Vey, assignor to Continental Rubber Works, both of Erie, 

 Pennsylvania. United States patent No. 1,204,213.] 



Tire Tread Cementing Machine. This applies a coating of 

 cement to the buffed surfaces of tire casings prior to applying 

 the tread bands. [John M. Hibner, assignor to Morgan & 

 Wrigfft, both of Detroit, Michigan. United States patent No 

 1,205,203.] 



Yarn Impregnating Apparatus. This comprises a U-shaped 

 solution tank in which the threads to be impregnated are im- 

 mersed for a considerable period, the surplus liquid removed from 

 the threads, which are then delivered to the twisting appara- 

 tus. [Walter R Uenman, assignor to The Miller Rubber Co.— 

 both of Akron, Ohio. United States patent No. 1,206,420.]
