supported in the base of the housings and the six hydraulic 

 rams operate in perfect unison in raising and lowering the steam 

 platen. This is 24 inches wide and 16 feet long, chambered 

 for steam and attached so that the e.xpansion due to the heat is 

 provided for. The top platen is of the same dimensions, sim- 

 ilarly constructed and attached to the upper part of the housing. 

 While this press is used for forniuv.; ami cunii- ti 



it is eciuallv serviceable in vulcanizing hose, matting and belting.

MACHINERY PATENTS. 



THE WINKLEY SOLE CUTTING MACHINE. 



THE machine illustrated in the drawing is specially designed 

 to automatically cut shoe soles from sheets of rubber stock 

 and to impress thereon the medallions which usually appear near 

 the middle of the sole. , , , •, d ^u 



The frame of the machine is designated by A, while B are the 

 extensions supporting the moving work table C. on which the 

 cutting is done. This table is composed of thin, flat plates pivoted 

 together, forming an endless carrier that is driven by the sprocket 

 wheel D The sheets of rubber stock are placed upon the table 

 bv the operator, and as they are advanced into position to register 

 w'ith the cutters thev are operated upon by pressure rollers which 

 press them uniformly and evenly upon the surface of the table. 



The two cutting mechanisms F, F, which are mounted over this 

 table are driven bv independent gearing, cams and levers 

 operated from the main shaft. Each cutting mechanism com- 

 prises a form or pattern corresponding in outline to the sole to 

 be cut, a cutter carrying head, and feeding and controlling 

 mechanism which causes the cutter to travel in a path corre- 



sponding to the outline of the pattern. Each cutter is operated 

 and controlled independently of the other, and as each cutter 

 finishes cutting a sole its operating and controlling mechanism 

 is thrown out of operation. When both cutters have finished 

 their operation the heads are raised to disengage the cutters 

 from the stock, and mechanism for moving forward the 

 table to present a new portion of the stock to the cutters is 

 thrown into action. As the shifting movement of the table is 

 completed the medallion impressing mechanism G, G, is operated 

 to impress one or more medallions upon the cut soles.

APPARATUS FOR IMPREGNATING TIRE FABRICS. 

 Kremer's invention relates to a process and mechanical ap- 

 paratus for impregnating cotton fabrics with rubber or other 

 materials suitable in the preparation of fabrics for use in the 



rtical section of the apparatus 



ito the interstices of the 

 excess rubber is removed 



manufacture of tire casings, 

 is shown in the illustra- 

 tion in which .1 is the 

 solution tank. B the dry- 

 ing chamber and C' the 

 compartment where the 

 saturated fabric is 

 wound up on a roller. 



In operation the fab- 

 ric is fed from the roll 

 D into the rubber solu- , 

 tion, where the air is 

 removed by a pair of " 

 rollers that also force the solutiu 

 cloth. As it passes out of the tank 

 by another pair of rollers. 



The fabric (which is attached to the cross bar £) is then 

 drawn through the drying chamber by the endless chain belt F, 

 driven by a series of sprocket wheels, and is wound up on the 

 roller G. Hot air is introduced to the drying chamber through 

 valve H, and circulation is maintained through pipe / located at 

 the top of the chamber. The condensed solvent is drawn off 

 through a pipe provided for that purpose at the bottom of the 

 chamber. [F. W. Kremer, Carlstadt, New Jersey. United States 

 patent Xo. 1,174.995.] 



COVERING HOSE WITH LEAD PRIOR TO VULCANIZING. 



This machine is primarily adapted for forming a tube of lead 

 around rubber hose to perform the services of a mold during 

 Ihe process of vulcanization. It may also be used with other 

 machines for making 

 metallic tubes, without 

 regard to whether such 

 tubing is formed around 

 rubber hose or a tube of 

 other character. 



Referring to the illus- 

 tration, A is the base of 

 the machine that sup- 

 ports the block B, pro- 

 vided with a die cham- 

 ber C in which the die 

 D is supported by a 

 threaded sleeve. The for- 

 ward end of this die co- 

 operates with the female 

 die E supported in the die carriLi / 



The molten metal is discharged into the passage G from the 

 supply chambers H and /. The block / swings on a pivot and 

 automatically closes the chamber / when pressure is applied 

 by the plunger K to the molten metal in chamber H. When 

 pressure is applied to the metal in chamber /, the opposite 

 chamber is closed by the swinging block / and the metal from 

 chamber / is discharged into the passage G. From here the 

 metal is forced through the dies D and E which encase the 

 hose in a tube of lead as it passes through the openings pro- 

 vided for it in the dies. 



In order to partially cool the molten metal and head block, 

 the latter is provided with angular chambers M M, through 

 which water is caused to flow. [C. D. Garretson, Wilmington,
