THE INDIA RUBBER WORLD 



[June 1, 1914. 



Referring to the drawing, uhicli shows a section of a mold 

 for making snti riilibcr biilbj siith as are used on atomizers, 

 the mold shells ./ are form d w.th flanges y^. which inter-engage, 

 iind also lit into rc.-esses in plalci C. These plates are con- 

 nected with the npp.T and lower frame plates D and E hy ?cr, w 

 bolts !■', and the mold sections are chimpcd together by tluimb 

 screws C. The mold 

 shells .-/ are cast /D 



from soft metal such ^ 



as tin, type-metal, 

 aUiniinum or alloy, 

 and are finished 

 smooth by swaging. 

 A mold of this sort 

 may be made of ten 

 cent metal, and 



weighs ten pounds. 

 Thus 500 tw-o-cavity 



auto horn hiilb molds would weigh only 10,000 pounds as against 



40,000 pounds weight for the same numl)cr of molds as made 



today. 



Quick curing and cooling, lengthened life, more frequent use, 



economy in metal, and greater care in handling are some of 



the results obtained. 



The inventor is William Eggers, of P.rooklyn, New York, a 



practical mold maker kni.wn to the whole trade.

, HU3BER STOCK CUTTING SHEAR. 



A convenient form nf shearing machine for cutting rub- 

 ber stock which is to be placed in molds to be cured — such 

 as horseshoe pads, rublier heels, and other small rubber articles- 

 has been introduced by a manufacturer of rublier machinery. 



This machine is 

 built to be oper- 

 ated either by 

 hand or foot 

 pressure. the 

 shearing action 

 of the knife on 

 the stock being 

 such as to pro- 

 duce a clean, 

 smooth cut. The 

 knife is of fine 

 tool steel and 

 will hold its 

 cutting edge 

 w i t h o u t fre- 

 quent sharpen- 

 ing. Where the 

 knife comes in 

 contact with the 

 frame there is 

 placed a hard- 

 Shearing Machine for Cutting Rubber wood strip in a 

 Stock. groove of the 



frame to protect the cutting edge. The frame is of cast iron and 

 is machined at the joints. Altho the machine shown is of 

 small size, shears of larger construction for special purposes' 

 may be built to order. (Birmingham Iron Foundry, Akron 

 .Branch, .'\kron, Ohio.] 



VULCANIZERS FOR EVERY PURPOSE. 



The Biggs Boiler Works Co.. of .\kron, Ohio, has just 

 issued catalog No. 16 covering tire repair equipment. The 

 catalog contains 40 pages showing different styles of both 

 vertical and horizontal tire and tube vulcanizers, as well as 

 small apparatus for the repair shop and garage. Several 

 pages are devoted to directions for installing and operating 



THE WERNER Sc PFLEIDERER CO. OPENS A WAREHOUSE. 



In connection with its New York office, 1031 Tribune Building, 

 the Werner & Pfieiderer Co. has opened a warehouse in that 

 neighborhood where prospective customers can see all the vari- 

 ous machines made by the company — washing, masticating, com- 

 pounding machines, as well as rubber solution and cement mak- 

 ing machines — thoroughly demonstrated, so that they can judge 

 their value for themselves. Customers from out of town will 

 (ind it to their advantage to make an appointment in advance, 

 and if tliey wish, they can bring their own materials to be used 

 in tliese demonstrations. 



AKRON-WILLIAMS TIRE REPAIR OUTFITS FOR FORD SERVICE 

 STATIONS. 



The Ford Motor Co. recently ordered Akron-Williams 

 localized heat tire repair outfits for each of its fourteen serv- 

 ice stations. As this was done after very thorough testing 

 of the quality and efficiency of various repair outfits, it may 

 be considered a great compliment to the Williams Foundry 

 & Machine Co., of Akron, which manufactures these outfits. 

 The "A-W" tire repair vulcanizers have the exclusive feature 

 — which is patented — of localized steam chambers. Each sec- 

 tion is heated by three separate steam chambers, which makes 

 it possible to apply the heat exactly where the repair is to 

 be made and to prevent over-curing or burning. 



ANOTHER TIRE TEEAD, 



Miller's Non-Skid "C o g" 

 Tread is noted for its triple 

 traction surface and surplus 

 rubber to resist rut-wear and 

 which suffices, when ground- 

 tread is worn smooth, to pro- 

 vide a two-thirds traction sur- 

 face, obviating the necessity of 

 chains on slippery drives. The 

 corrugated or "Cog" tread sur- 

 face is said to promote a highly 

 satisfactory action and to be 

 wear resisting. (Chas. E. Mil- 

 ler, Anderson, Indiana. ) 



RUBBER GARTERS WITH 

 POCKETS. 



It is currently reported — 

 whether the report is true or 

 not it is impossible at this time 

 to verify, there being no statis- 

 tics in this office bearing on 

 the subject — that some women 

 at some times deposit their 

 valuables in their hosiery. In 

 order to accommodate ladies with such tendencies, and to make 

 it easier for them to deposit their valuables where they can be 

 obtained with a fair degree of readiness, a woman residing in one 

 of the smaller towns of New York State has devised an elastic 

 garter — made presumably of rubljer threads — which is in reality a 

 double garter with a number of pockets sewed in between the 

 two, the pockets of course opening at the top. The theory is that 

 diamond rings and other small but valuable objects can be de- 

 posited in these bags, the garter put in its place and the desired 

 security obtained. It is hardly necessary to add that to make 

 this movable deposit entirely secure the garter should be a good 

 fit and the rubber of such a quality that it will not give way while 

 the wearer is about lier dailv walks.
