RUBBER SHOE SOLE ROLLING MACHINE. 



VERY few machines are in use in the manufacture of rubbei 

 boots and shoes; in fact the whole process of manufacture 

 is a hand process. Winklcy's machine, however, i 

 sinned imt only to apply the sole to the otherwise finished shoe, 

 but to roll it, pound it, and stick it securely, practically copying 

 the motions used bj the operative with the hand roller. 



I In machine is quite complicated and one outline cut is hardly 

 sufficient to illustrate it in detail. The important parts, how 

 ever, are shown and they are the shoe itself, which on its last 

 is rarried on a jack; above this works a shoe arm to which a 

 roll is attached. The jack is moved backward and forward 

 and turning, while the roll above it is vibrated and manipulated 

 so that every portion of sole, heel, shank, forepart and beveled 

 edge are thoroughly and quickly covered. This is a double ma-

chine and finishes a pair of shoes at one time. The illustration 

 shows only one-half of the machine working on one shoe. [E. E. 

 Winkley, United States patent No. 1.124,190.] 



INNER SOLE CUTTING MACHINE. 



T^HIS machine can be used for slitting any fabric in strips 

 * with straight or curved edges. Mere it is described in refer- 

 ence to cutting sole linings, which are then wound with the 

 proofed side down on reels so that the heel strip unwinds first. 

 The two side frames support the bearings of the various shafts 

 and the driving mechanism. The cross frame which carries 

 the lower cutter shaft, brackets, gearing, etc., is bolted to the top 

 of the frames. Directly above this is a similar frame that car- 

 ries the upper cutter mechanism. This is hinged to give access 

 to the parts. The cloth is fed from the fabric roll around a 

 guide roller and under and over two tension rollers. It then 

 passes between the upper and lower revolving cutters and is 

 slit into strips which then pass under and over the tension 

 rollers, and between the feed rollers to the wind-up reels. The 



toe strips are wound on the upper reels, while the heel strips 

 are wound on the lower reels. These are afterwards rewound

MACHINE FOR MAKING SHEETS OF ASBESTOS 

 AND CEMENT. 



THIS is a machine designed to make multiple layers of as- 

 bestos fiber and cement and form them into sheets. The 

 illustration shows an end view in section. The perforated drums 

 are mounted in hearings supported by side frames not shown in 

 the drawing. They revolve toward each other and are driven 

 from a cross shaft by worm and pinion gearing. The two hop- 

 pers containing the material are provided with agitator blades

that prevent the mass from settling to the bottom. The two 

 perforated feed rollers are mounted parallel to the drums and 

 revolve in the same direction. These rollers spread the material 

 over the surface of the revolving drums and carry the two layers 

 between their adjacent surfaces, where the material is formed 

 into a continuous sheet. 



The feed of the material on the right is regulated by ad- 

 justing the feed roller in the direction of the arrow, while the 

 feed of the material on the left is constant. (G. Oeisler. German 

 patent No. 231,713.]
