THE INDIA RUBBER WORLD 



[July 1, 1915. 



suspended on a cable, the ends of which are attached to pivoted 

 arms carrying the roller supports 117. The rollers act obliquely 

 and their inclination is adjustable to facilitate working on the 

 beads. A lever is provided for swinging the arms 117, clear 

 of the core against the action of the weight, which lever 

 may also be used to relieve or increase the pressure of the rolls 

 trimming the edges of the finished founda- 

 tion, a pair of cutters is fitted in adjustable holders on slides near 

 the edges of the carriage 63. [W. C. Stevens, British patent No. 

 3S85, 1914.] 



OTHER DEVICES. 



Tike Shoe and Method of Making.— The frictioned fabric 

 of loosely woven material is wound spirally around an 

 annular form. The casing is then split around its inner 

 hery and the strips folded back, enclosing the bead wires 

 and reinforcing the tread. I Charles T. Dickey, assignor to 

 Voorhees Rubber .Manufacturing Co.; United States patent No. 

 1,138,092.] 



icess of Making Inner Tubes.— The stock is forced over 

 a mandrel to which graphite has been applied. The tube is then 

 vulcanized, and when reversed it presents a smooth, durable 

 outer surface. [Arthur W. Savage; United States patent No. 

 1,138,250.] 



Mold for Tire Fillers. — This is for casting a resilient tire 

 filler in the form of a ring having a continuous channel on its 

 inner periphery. [H. J. Hardie ; United States patent No. 

 1,139,276:] 



M \ki.M, Collapsible Cores. — The separate segments are cast 

 in dry sand molds and then assembled, producing a complete 

 collapsible core; the customary way being to first make the 

 core and then cut it into segments. [Peter Bacher ; United 

 States patent No. 1.139.325.J 



Collapsible Core Locking Device. — The locking ring is split 

 and the ends are drawn together by the bolt-shaped locking de- 

 vice. This aligns the sections of the core and locks them in 

 place. [Martin D. Kuhlke ; United States patent No. 1.140,045.] 



Pneumatic Tire Core. — This is a rubber core intended to be 

 inserted in the inner tube or casing as a substitute for air. 

 [Monsel Bracey; United States patent No. 1,140,242.] 



Sheet Metal Collapsible Core. — The core sections are cham- 



i red for steam, and have relatively thin walls as compared 



with the heavy cast-iron sections of the ordinary core. [Joseph 



Chalfant and Harve G. Haun ; United States patent No. 



1.140.499.] 



Tire Repair Air Bag. — This bag is designed to distend and 

 support the walls of collapsible tubes during vulcanization in 

 repairing automobile tires. [Peter Powell, assignor to Standard 

 Tire & Rubber Co.; United States patent No. 1.140.527.] 



i rcular Braider. — This machine makes tire casings in tubular 

 form with closer mesh at one side than at the other, and is 

 particularly adapted for spring wire braiding. [Adolph L. De 

 1 ei aw; I'nited States patent No. 1.141.382.] 



A New \ i lcanizer to Be Carried in the Car. — The heat is 

 applied and at the same time limited by improved devices. The 

 clamping arms and screws are collapsible so that the vulcanizer 

 occupies a small space. [James E. Bancroft ; United States 

 patent No. 1.141,519.] 



Tire Repair Vulcanizer. — This device can be used for bicycle 

 as well as automobile tires. A variety of molds is not required 

 as the sides of the vulcanizer are adjustable. [Charles E. Miller; 

 United States patent Xo. 1.142,526.] 



A Ramless Press Vulcanizer. — The usual hydraulic ram and 

 cylinder are done away with in this new machine. The vul- 

 canizer cylinder contains a piston, suitably packed and fitted, 

 upon which the molds are placed, and the piston or ram is 

 operated by hydraulic pressure. Thus the vulcanizer serves the 



double purpose of a ram cylinder and a vulcanizing chamber. 

 The head is raised and lowered by two small hydraulic rams 

 fixed to the side of the vulcanizer. [J. H. Xuttall and David 

 Bridge & Co., Limited. British patent No. 978, 1915.] 



Cementing Machine.— This invention applies cement or 

 other coating materials to stock, and is particularly adapted for 

 nting leather shoe uppers. [Hiram Holden; United States 

 patent No. 1,138,565.] 



Sole and Welt Cementing Machine. — The novelty in this de- 

 vice consists in the regulation and control i if the cement, and 

 also in the means for cleaning the brush. [Charles P. Stanbon, 

 assignor to United Shoe Machinery Co.; United States patent 

 No. 1.138,903.1 



Duplex Cement Applying Mai mine. — Where parts of leather 

 footwear in duplicate, or rights and lefts placed face to face, are to 

 be cemented, this machine applies the cement to both of the 

 outside surfaces at the same time. [William F. Lautenschlager ; 

 United States patent No. 1.140,602.] 



Sole Cementing Machine. — This is used in the manufacture 

 of leather footwear, where it is sometimes necessary to apply 

 cement to one side only of a piece of stock and at other times 

 to both sides. [Michael F. Brogan, assignor to United Shoe 

 Machinery Co.; United States patent No. 1,141.311.] 



A New Mixer Roll. — The chambers between the outer shell 

 and the hollow central shaft are supplied through the latter with 

 heating or cooling fluid. [Miller & Co., and J. White: British 

 patent No. 715, 1914.] 



Latex Coagulating Apparatus. — Shallow pans containing the 

 latex are supported in tiers on frames within smoke chambers. 

 The latex is coagulated by smoke produced in a wood combus- 

 tion furnace. [F. Ripeau ; British patent No. 2,281, 1914.] 



THE WILLS OVTiRFXOW TRIMMING MACHINE. 



This compact, light running machine is demonstrating its use- 

 fulness as an efficient labor-saving device in many leading Ameri- 

 can rubber factories, where it may be found singly or in groups — 

 up to fourteen machines in number. A practiced operator with 

 one of these trimmers can do perfect work, and in speed of out- 

 put (2,500 pairs of heels per day) exceed that of the most ex- 

 pert hand-maker fully 200 per cent. Although designed primarily 

 for heel trimming it can be made, by means of suitable attach- 

 ments, to trim a variety of rubber work, such as soles, basin 



plugs, stoppers, valves, discs, diaphragms and numerous other 

 small molded specialties. The machine consists of a pair of 

 rotary shears, sensitively regulated by the operator with rela- 

 tion to the position of the overflow to be removed. The article 

 is hand-guided or rotated past the cutting point as it rest- on 

 the adjustable work table. 



The trimmer, in material, workmanship and design, embodies 

 the best modern practice. It is a bench machine, requiring only 

 i ne-eighth horse-power for its operation. [Arthur J. Wills, North 

 Brookfield. Massachusetts |
