fabrics, and it is particularly adapted to cutting off the beads of 

 worn-out tires. 



The construction is extremely simple, and its operation may be 

 clearly understood by referring to the illustration and the fol- 

 lowing brief description: 



In removing the beads from clincher tires, the casing is placed 

 upon the horizontal guides and the vertical rollers are adjusted 

 to the inner circumference of the tire. When the treadle is de- 

 pressed the revolving cutter penetrates the wall of the casing 

 and the pressure of the collars on the cutter arbor revolves the 

 tire and the bead is quickly removed. The tire is then reversed 

 and the other bead cut off in the same manner. [Reichel & 

 Drews, Chicago, Illinois.]

THE MOMENT ADJUSTABLE COMPOSITION SOLE CRAMP. 



The shortage of sole leather has greatly developed the sale of 

 composition soles that are now being manufactured both here and 

 abroad in large quantities. The device here shown for attaching 

 soles to boots and shoes is a timely suggestion from England, 

 where it is used with success. 



A layer of special cement with strong adhesive properties is 

 first applied around the edges of the sole about one inch wide 

 and allowed to dry. It is then heated, placed on the shoe and 



hammered down tightly on the last. The welt grips being opened 

 widely, the cramp is placed on the shoe and the grips fitted over 

 the welt or middle sole. The thumb screws are then tightened 

 and the welt pressed down against the sole with nippers or the 

 handle of a wedge-shaped knife, making a close joint all around, 

 and the shoe is left in the cramp for ten minutes or until the heel 

 is benched. 



The device is adjustable to the right or left shoe by moving 

 the sole plates up or down and better results are obtained by 

 using a last in applying soles with this appliance. [The Revolite 

 Co., Limited, Manchester, England.] 



A NEW ALLOY FOH RUBBER MOLDS. 



Rubber molds cast from ABCilium metal alloy are said to be 

 so smooth that their surfaces do not require machining, polish- 

 ing only being necessary, and in some cases even this may be dis- 

 pensed with. 



They are, moreover, impervious to all acids used in the manu- 

 facture of rubber goods and unaffected by excessive heat or soap- 

 stone blasting. 



The thermal conductivity of this metal is even greater than 

 that of copper, consequently an instant heating or cooling is 

 possible. A mold made of this alloy is 70 per cent lighter than 

 an iron mold made off the same pattern, and may be constructed 

 lighter than iron molds now in vogue. It is claimed that cast 

 iron tire molds weighing 1,000 pounds will weigh less than 200 

 pounds when made of this alloy, all factors of safety being con- 

 sidered. The specific gravity of ABCilium is 2.S1. which is 

 lighter than 99 per cent pure aluminum. [The A. B. C. Castings 

 Co., Cleveland. Ohio.] 



and novel 

 construction and one that 

 has been designed to 

 meet the requirements of 

 modern tire production 

 is shown in the illustra- 

 tion. This is a multiple 

 opening bead press with 

 seven round steam 

 platens. Attached to the 

 press is a hydraulic ele- 

 vator, the platform of 

 which is guided on two 

 additional columns, which 

 are part of the press. 



Attached to the ele- 

 vator table is a platform 

 supported by rods. This 

 platform is for the oper- 

 ator, who rises with the 

 elevator and removes the 

 molds from the various 

 openings. This arrange- 

 ment saves considerable 

 floor space, as all the 

 molds are loaded on the 

 elevator instead of being 

 deposited on long oper- 

 ating tables, as is usually 

 done. [Southvvark Foun-

THE NEW ERA BRAIDER. 



The following description of a new braider should be of par- 

 ticular interest to manufacturers of elastic tapes and braids, as 

 this machine is so constructed that it is almost impossible for 



oil to get on the rubber or 

 finished braids. 



-Among the advantages 

 claimed by the manufac- 

 turers are fewer and sim- 

 pler parts, increased speed, 

 ease of operating, accessi- 

 bility, safety to operator, 

 freedom from shadows 

 and cleanliness of work. 



Perhaps the most nota- 

 ble change is the self- 

 lubricating feature, the 

 entire mechanism running 

 iu oil. It is necessary, 

 therefore, to oil only once 

 in several months, which 

 makes a considerable dif- 

 ference in production, be- 

 sides saving time. All 

 gears arc covered, reducing liability of accident and giving a 

 better rating by liability insurance companies. The studs are 

 cast integral with the base, and are constructed so that they 

 allow a positive fastening of the plates or "quoits." 



All gears used in the machine are cut, and the construction 

 is such that the carriers bear directly upon the surface, and are 

 revolved by smooth cam action in place of being knocked around. 

 This new action allows increased speed, with less strain and 

 breakage of the yarn. 



The carrier itself is designed to accommodate all sizes and 

 types of bobbins, and unless otherwise ordered the machines are
