RUBBER SOLE GANG MOLD. 



THIS invention provides strong molds that do not break 

 easily and with interchangeable parts on which uniform 

 pressure may be maintained, for producing a variet) 

 of soles. The plan view on the right show- the middle sec 

 tion of the mold ./ with the top and bottom plates B and ( 



removed, while on the left is a vertical section showing the 

 plates in position. In the arrangement of the four single molds 

 /». shown in the drawing on the right, the toe oi one mold is 

 cent to the heel of the next, which gives greater strength to 

 the heel portions of the forms. The molds are uniform in thick- 

 ness with the middle mold, thereby preventing uneven pressure 

 On the contour frames. [Charles II. Hill. I nilcd States patent, 

 No. 1.136.336.1 



MACHINE FOR COVERING ROLLS OF FRICTION TAPE. 

 The operation of the machine is a- follows: A series oi 

 uncovered tape rolls is placed in the roll carrier, resting upon 

 the upper laps of the endless feed bands. The tin-foil is passed 

 under the feed roll and laid upon the periphery of the bed roll. 

 This is set in rotation and the uncovered tape rolls are fed one 

 by one to the holding jaws or arms that deliver them to a 

 chute with guides which present the rolls in proper position 

 above the bed roll. The tape roll is then pressed down on the

cylinder having ends which project beyond the sides of the tape 



roll. A folding device folds these projecting ends against the 



sides of the tape roll, as it is carried through the passage from 



which it drops into the delivery chute. [C. J. Landin, assignor 



to Boston Woven Hose & Rubber Co., United States patent.
