ROYLE THREE-WAY HEAD STRAINING MACHINE. 



■ I "I I K illustration shows a new reclaiming strainer designed 

 * for heavy work, and plenty of it. The body of the ma- 

 chine i- supported on a broad, square base. It is chambered 

 for heating or cooling, and is accurately bored to receive the 

 large and powerful stock norm. This has ample thrust bearings, 

 is driven by a belt and cm spur gearing, and is capable of hand- 

 ling large quantities oi stock. The feed hoppers are large and 

 specially constructed for capacity. The three-way head lias 

 heating or cooling chambers, and the holes in the plates are 



square instead of round. This feature is a decided improve- 

 ment in straining machines where capacity is desired. I lie 

 usual wire gauze strainers can be removed for cleaning by un- 

 screwing the octagonal headed bushings with the special socket 

 wrench provided for that purpose. [John Royle & Sons, 1'ater-

SPRIGG'S MACHINE FOR REPAIRING RUBBER 

 GLOVES. 



■ I 'HIS machine is designed for repairing glove tips. Fourteen

finger trees are arranged seven on each side of an elec- 



trically heated vulcanizing platen. They are pivoted on rods 

 and the ends thai rest on the platen are flattened. The finger 



position on the platen, and when each ringer and tree has been 

 similarly treated they are all clamped down. \ thermometer at- 

 tached to the platen indicates the degree of heat. 



THROPP-DELASKI TIRE MAKING MACHINE. 



' I 'HE illustration is a front view showing a tire core mounted 

 * on a spider revolved by a driving shaft. This shaft ex- 

 tends through the housing, has re\rrsc gearing and is connected 

 to .1 variable speed device so that the con i- driven at various 

 speeds to the right or left. A cylindrical head slides in a cyl- 

 inder bolted to the overhanging stanchion and supports a roll 

 of fabric in a frame. It is moved vertically by a screw, bevel 

 gearing and an inclined shaft operated by a hand wheel

The fabric, cut in bias lengths, is passed under a guide roller 

 over the wooden friction roller, under another guide roller, an.! 

 is then pressed firmly on the periphery of the core. At the same 

 time the interposed wrapper is wound on a take-up roller. 



Mounted on a sliding carriage are two plates that swing in 

 opposite directions in a curve equal to the periphery of the core. 

 These support the two motor driven forming discs. 



The various layers of fabric are laid on the core and then 

 stretched and formed down by these discs. The bead rings are
