PRICE S VACUUM VULCANIZERS. 



IN the manufacture of tires, footwear, hose, and in fact prac- 

 tically all articles wherein rubber forms a component part, 

 the elimination of air and moisture is verj necessary to pro- 

 duce reliablt g 1- Price accomplishes this result by building 



the article in a 

 vacuum. I lis inven- 

 tion covers ibis prin- 

 ciple as applied to the 

 manufacture of foot- 

 wear, tires, hose and 

 tbe building up of 

 plies of fabric and 

 rubber. Tbe illustra- 

 tion shows only tbe 

 apparatus for manu- 

 facturing r u b b e r 

 boots. A is tbe air 

 tight casing. B is 

 the cover with a removable plate of glass C, and D is the 

 vacuum pipe. The air tight bag E is placed around the boot to 

 nt direct contact with tbe air. Tbe bag is subsequently re- 

 in. ..I'd, and the l">"t subjected to tbe usual vulcanizing process,

RIEDER'S FOOTWEAR VULCANIZER. 



This invention may be said briefly to consist of a drum 

 that rotates within a closed vulcanizing chamber. Tbe articles 

 being vulcanized are revolved with the drum for tbe purpose of 

 uniform vulcanization 



Tbe oven or chamber ./ contains a heating coil B regulated by 

 a valve. Within tbe oven a drum C is supported in bearings

and has mounted thereon a serii - oi ~ix stick carriers D. The 

 adjaci ol the carriers have a series ,,f parallel angle 



iron rack- £ which bold tbe sticks upon which the lasted rub- 

 ber shoes are carried during vulcanization. These stick carriers 

 are supported on shafts and revolve in bearings mounted upon 

 the end- of the drum. 



The drum is mounted upon and keyed to a shaft F, extend- 

 ing through and supported in bearings in the walls of the ovens 

 and is driven by a reduction gear connected to tbe main driving 

 shaft. 



The stick-carriers while revolving with the drums are made to 

 maintain tbe sticks and lasts constantly in a horizontal or level 

 position, by sprocket wheels driven by sprocket wheel G and 

 an endless chain /. 



The sticks with the lasted rubber shoes are set in tbe notches 

 of the different stick carriers, tbe drum being turned by hand 

 to enable this to be done. When the carriers are fully charged 

 the drum is revolved by power, steam is admitted to tbe coil, and 

 tbe vulcanizing operation otherwise carried on in the usual way. 

 Thus each article passes through the zones of the highest, me- 

 dium, and lowest temperatures. [T. H. Rieder, United States 

 patent X... 1.138.791.] 



DIAGONAL WEFT LOOM. 



litis is a power loom for weaving fabrics in which tbe weft or 

 filling is disposed at other than a right angle with respect to tbe 

 warp threads, preferably at an angle of about forty-five degrees. 



/- 



3r- 



The lay and harness are arranged diagonally to the longitudinal 

 axis of the loom and the warp threads, the latter passing, as is 

 usual, from a beam, through the harness and through the reeds 

 carried by the lay. which swings to and fro in the direction of tbe 

 warp and diagonally to the length of the lay. 



In the illustration, the side frames A, are connected together 

 by ep>ss beams, with arches B, extending between the frames at 

 the top for supporting the harness frames. The arches B lie 

 at an angle of about forty-five degrees and support the harness 

 at the same angle. 



The harness frames, any number of which may be used, are 

 offset sli^hth s, , that their side edges will be parallel to the 

 warp. This is done to enable the warp to he moved vertically bj 

 the beddles of the harness when the latter is raised and lowered, 

 without causing undue friction on the warp threads. The hed- 

 dles are moved by a well known type of head motion and com- 

 prise a number of jacks C, in the form of elbow levers, from the 

 upper end of ir.ic}) of which two straps D, extend, passing over 

 rollers £ and down to the harness frame, there being two of said 

 straps for each frame. On the opposite or horizontal ends of the 

 jacks, "ther straps pass around pulleys at the bottom of the frame. 

 thence toward the center of the frame and around pulleys, not 

 shown, to the bottom of the harness frame. The jacks are 

 operated by devices well understood and therefore not shown.
