drum-ring is used to distend the band A. Owing to the differen- 

 tial movements of the cylinder and the spider, the expanding 

 pressure is applied throughout at the center of the band. At the 

 end of the upward travel, split rings snap into grooves in the mid- 

 dle drum-ring, which is removed with the shaped casing and tube 

 for the finishing operations. The plunger is lowered, the arms D 

 are swung centrally inwards to clear Ihc drum structure, which 

 is then removed by the tackle. The machine is adapted for 

 shaping tire casings of various sizes by the substitution of graded 

 rings and drurns. — E. Hopkinson, New York, N. Y., and H. V.

MACHINE FOR MAKING TIRES 



This apparatus shown in Fig. 2 consists of a series of plates, 

 coimected to a ram, with necessary air reservoir, valves, gages, 

 and a mechanically expanded ring. In operation, a partially vul- 

 canized flat-sectioned tire cover is expanded to the form of an 

 ordinary tire cover by the direct action of pressure. It is retained 

 in its expanded condition for vulcanizing purposes by a mechan- 

 ically expanded internal ring. The tire cover is placed between 

 the plates B. The ram C, automatically operated, advances the 

 lower plate towards the upper. Air admitted to the chamber D 

 from the reservoir or compression tank, expands the tire cover. 

 The center part is forced outwards to give the desired shape. 

 During this process, the expansion ring £ is held in its contracted 

 form by a pin and the lever F. When the free end of the lever 

 comes in contact with the upper plate, the ring is released. It 

 then expands under the action of internal springs until it fills the 

 space within the expanded tire cover. After the air has been 

 allowed to escape, the plates are separated. The tire cover is 

 removed in its expanded form on the ring and vulcanized. A 

 fluid-tight joint between the tire cover and the plates is made for 

 beaded tires by means of a separate ring and a packing ring, or, 

 for wired-on tires, by means of an L-section packing ring. — T. 

 Sloper, Southgate, Devizes, Wiltshire, England. British patent 

 No. 150,792. 



MOLDING AND VULCANIZING TIRES 



This machine relates to the method of manufacturing rubber 

 tires by the internal-pressure system. Referring to Fig. 3, the 

 mold shells A and B for the tire casing are mounted inside of, or 

 form part of the containers C. These containers are constructed 

 to provide the necessary space for the pressure. Such spaces form 

 a continuous passageway for the pressure from the supply pipe, 

 which is supplied as soon as the mold is closed. The shells A 

 are mounted in the containers C by screws. The containers are 

 held together by bolts and provide a pressure tight space. Pres- 

 sure enters by way of a channel formed between an upstanding 

 flange and the inner surface of the core D. A vent in the core 

 allows the air to escape from the inside of the tire casing. The 

 heating spaces around the mold may have a separate supply of 

 heating fluid. In order to heat up quickly a reserve of hot fluid 

 is provided in a steam heated vessel E. 



The containers C are preferably horizontal, as shown at F, the 

 lower one being fixed in a permanent position while the upper 

 half is hinged to it and operated by a hydraulic cylinder with bal- 

 ance weight. When arranged in rows, the molds are served by 

 an overhead carrier. While one group is being emptied another 

 may be closed with casings under treatment. The cores may be 

 solid, collapsible, or in the form of an inflatable tube. — Dunlop 

 Rubber Co., Westminster, London, and C. Macbeth, Birmingham, 

 England. British patent No. 150,373.
