McEWEN'S TIRE VULCANIZER. 



v. 



""THE McEwen patented portable vacuum vulcanizer for rubber 



■*• tires has for its chief characteristic the absence of steam 



in its operation but is referred to as being capable of producing 



a higher heat and a better heat for vulcanizing rubber, fabric, 



leather, or other materials 

 into a homogeneous mass 

 without any injury to any 

 of the materials employed 

 than any of the other sys- 

 tems in use. It is stated 

 that a heat from 1 deg. to 

 S00 degs. F. can be obtained 

 readily in this vulcanizer 

 with positive regulation in 

 a very short space of time. 

 The idea is that this vul- 

 canizer facilitates the re- 

 covering and repairing and 

 also the building of auto- 

 mobile tires, and is cheaper 

 in operation than a steam 

 plant. These vulcanizers 

 are economical in the 

 amount of space occupied. There is no bolting of any door or 

 cover required in opening or closing the apparatus; either the 

 opening or closing is accomplished with one operation. The in- 

 ventor and patentee of this apparatus is Mr. Fred E. McEwen, 

 No. 562 West One Hundred and Sixty-fourth street, New York.

THE "IDEAL" SLEEVE FOR TIRES. 



A DEVICE of interest to motorists, and one which has 

 ** proved of much excellence, is illustrated herewith. It is 

 designed to insert on the inner side of a tire tube to remedy a 

 blow out, or, if applied to a weak spot, to keep an old shoe in 

 service. The "Ideal" sleeve is made to conform -with the inside 

 of the shoe and completely take the strain from the latter. These

sleeves are made fr< .m high grade cotton duck, four to seven 

 plies, according to size, with beveled edges to insure a smooth 

 surface for the tube, and have a flap on each side which passes 

 over the rim to hold the sleeve in place. [Voorhees Rubber Manu-

THE "UNIVERSAL" STEEL CALENDER SHELL. 



' I 'HE rapidly increasing demand of late years for rubber prod- 

 * ucts made up from sheet stock has so taxed the manu- 

 facturers that practically a reorganization of shop practice has 

 been necessary. One drawback has been the matter of getting the 

 sheet stock ready for use after it has been milled, at the same 

 time maintaining the quality of the stock. An improvement has 

 been in the introduction of metal shells instead of wooden rolls, 

 the advantage of the former being manyfold. 



In the use of metal shells the heat of the stock is removed in 



half the time, as the heat from the inner portion of the roll is 

 transmitted through the metal to the hollow interior and then 

 carried away by ventilation, consuming the least possible time in 

 cooling the stock and still procuring a proper "set" to the stock. 

 By this more rapid removal of the heat it was found that bloom- 

 ing, where sulphur is used, has been materially retarded and 

 further, that the all metal shell used in the metal frame work of 

 the calender, forms an immediate ground for the static electricity, 

 generated by the friction of milling, and practically eliminating 

 magnetism of the stock. 



In addition to the above consideration has been the question 

 of producing a metal shell that will stand strain, and have a 

 maximum of strength with a minimum of materials. The 

 Universal steel calender stock shell manufactured by W. F. 

 Gammeter (Cadiz, Ohio) is offered to rubber manufacturers as 

 combining the desirable requirements above outlined. 



RUBBER READY FOR TAPPING. 



THE Tabasco-Campeche Timber and Fruit Co., Inc., with 

 properties in Mexico, are inviting subscriptions to an ad- 

 ditional issue of preferred stock, the proceeds of which are to be 

 used for extending their rubber plantation over a large area. 

 They will also acquire an important amount of mahogany timber. 

 The company are in a position to derive revenues at once from 

 the sale of mahogany and of rubber from trees now arrived at a 

 productive age. The headquarters of the company are at 

 Moberly, Missouri, where Mr. Ed. F. Haley, the president, and 

 Mr. James V. O'Leary, the secretary-treasurer, are business men 

 of high standing, with favorable connections elsewhere in the 

 United States and in Mexico.
