SWINEHART'S TIRE VULCANIZER AND MOLD. 



WHEN .i tire is being cured by hydraulic pressure applied 

 to the interior, it is sometimes injured by excess 



pressure. In this dew.. S////Il/ / I'''///////7////////i 



the excess pressure es- 

 capes automatically. The 

 tire is placed in the mold 

 and filled with water 

 through the pipe pro- 

 vided for that purpose. 

 The mold is then sub- 

 jected to pressure in a 

 h y d r au 1 i c vulcanizer 

 press and live steam ad- 

 mitted. This expands the water in the tire and presses the 

 casing against the inner surface of the mold. In case there 

 is excess pressure within the tire the relief valve opens auto- 

 matically and allows it to escape. [United States Patent 

 No. 1,122,333.]

THE JOHNSTON BEAD TRIMMER. 



THE machine shown in the illustration is used in reclaiming 

 scrap tires. It cuts off both beads of quick detachable or 

 clincher tires in one operation. It has a crowned roll A, driven 

 from the motor B by gears C and D. Two pressure feed rolls E, 

 covered by shields F, are held in contact with the roll A by 

 springs G. Back of the feed rolls are circular knives covered 

 by shields H and held down by springs /. The tire is cut and 

 one end fed into the machine under the rolls E and the circular

s sever the beads from the casing. The cutters are ad- 

 justed to cut off beads of all sizes of tires up to 6 inches. With 



perators the capacity is 25,000 pounds in ten hours. [The

ORREY'S Shoe Bottom Filler. — This machine keeps the 

 filler material continuously in motion and has a by-pass 

 through which it circulates when the delivery opening is closed. 

 The material is delivered and spread automatically on the shoe 

 bottom. All the operator does i> to place the shoes on the jacks 

 and remove them. The machine does the rest. [United State-* 

 patent No. 1,122,661.] 



Welti n's Hydraui ii Vuli wizek 1'kess. — This press has two 

 rams and cylinders which are bolted to opposite sides of a 

 al vulcanizer shell. The upper ends of the rams are at- 

 tached to a ring shaped cross-head, which has two hooks on 

 the underside for engaging and lifting the vulcanizer door. Two 

 rods attached to the cross-head pass through stuffing boxes in 

 the door and support on their lower ends a floating platen within 

 the shell. The outside rams and cross-head hooks engage and 

 raise the cover while the rods raise the platen. The heater is 

 then filled with molds and the door locked. The rams are raised, 

 and the rods and platen pull the molds up against the cover.

Staple's Rope Packing Machine. — This invention relates to 

 the manufacture of round packing in continuous lengths. Under 

 the frame of the machine are reels holding the strands of ma- 

 terial. These are passed through an assembling ring and around 

 a grooved wheel, where they are gathered together. This core is 

 then passed up through the center of a revolving spool table and 

 attached to a grooved wind-up wheel. Mounted on the spool 

 table are a series of spools containing strands of material. The 

 ends are attached to the core and the spool table is revolved, 

 winding the strands around the core as it is drawn through. 

 [United States patent No. 1,122,168.] 



Tire Fabric Strip Feeder. — Brucker's machine feeds strips of 

 frictioned fabric from stock rollers to a power driven tire core. 

 The reel frame is mounted on a shaft journaled in two side 

 frames. It carries four power driven fabric rollers and four 

 friction driven wind-up rollers for the lining. The feed of the 

 frictioned fabric to the core is regulated by a tension weight and 

 the lining is wound up on a separate roller. 

 When one stock roller is emptied another is 

 brought in position by turning the drum. 

 [United States patent No. 1,121,793.] 



N all's Take-off Reel. — This machine 

 spools fabric coated with uncured rubber and 

 interposes the lining at the same time. A 

 square reel frame is mounted on a shaft jour- 

 naled in two side frames. It supports at op- 

 posite corners two lining spool shafts driven 

 independently by chain belting from the center 

 shaft. The coated fabric is attached to the 

 empty fabric spool and the lining from the 

 lining spool is wound up with it when the 

 fabric spool is revolved. When the spo, .1 i-, 

 filled the reel frame is reversed by being 

 rotated This places an empty fabric and a 

 liner spool, previously placed in the frame, in 

 position to be filled with fabric and lining.

Dees' Collapsible Cire. — This core is in 

 four sections, joined by wedge keys and has 

 an annular water groove on the periphery. 

 An inlet conveys water under pressure to 

 this groove and the same pipe acts as a 

 drain. Tin tire is built up on the core and 

 wrapped or placed in a mold. Before or 

 during vulcanizing water is forced between the core and the 

 tire, which stretches the fabric. A small quantity- of -water 

 produces the desired result. [United States patent No 

 1,117,803.]
