RUBBER MACHINERY. 



THE COIL STEAM GENERATOR. 



'HE accompanying illustration shows a coil steam generator, 

 suitable for use in repairing plants of ordinary size. It 

 stands only 37 inches high and 

 weighs (when ready for ship- 

 ment with all its accessories) 

 only 400 pounds. It is made by 

 tlic Williams Foundry & Machine 

 Co., of Akron, (Ihio, and is known 

 as their "27." It is heated by 

 gas or gasoline. It has a central 

 8-inch drum which serves as a 

 water and steam reservoir, 

 around which are two spiral coils 

 of -H-inch double strength pipe, 

 through which water circulates. 

 There are about 40 feet of pipe in 

 these coils, and they, together 

 with the central drum, are at all 

 times exposed to an intense heat. 

 The whole chamber is enclosed 

 in an asbestos-lined jacket. It is 

 economical and rapid in operation. 



REMOVING GUTTA-PERCHA TROM GOLF BALLS. 



The accompanying illustration shows a machine invented 



for the purpose of removing 



M.ACHiNE FOR Removing Gutt.\ 

 Percha Covers from Golf Balls. 



the gutta-percha covers or ex- 

 teriors from golf balls that 

 have rubber cores. This 

 apparatus cotjsists of a press 

 having a number of dies, 

 preferably perforated, which 

 subject the golf ball to pres- 

 sure, while the parts of the 

 machine surrounding the 

 golf ball are heated to a 

 temperature of aliout 200 

 degrees F. 



The gutta-percha, balata, 

 or other similar substance 

 that is used as a covering 

 around the rubber core be- 

 comes soft and semi-fluid 

 at that temperature and 

 under pressure flows quite 

 readily and can be squeezed 

 out. while the vulcanized 

 rubber lliread or tape which 

 forms the core is not af- 

 fected by this ■ temperature, 

 but remains intact, and in 

 this condition is expelled 

 from the press. 



The golf ball is dropped 

 in at the top of the press, 

 the parts adjacent to the 

 ball are heated to the proper 

 degree by means of steam, 



the gutta-percha squeezed out of the perforations and the remam- 

 ing rubber core is then expelled from the machine. 



It will surprise a good many people to learn that we are 

 actually exporting hydro-aeroplanes. Mr. Glenn H. Curtiss, the 

 hydro-aeroplane specialist, recently received an order from Russia 

 and three from France for the style of machine which he has 

 invented. 



AN ENGLISH PUTTING OUT MACHINE. 



The Turner Co., Ltd., Leicester. England, makes a specialty of 

 hide end leather working machinery. The European headquarters 

 of the company are at F'rankfort-on-the-Main, Germany, the 

 American house being the Turner Tanning Machinery Company, 

 Peabody, Massachusetts. 



Thf. Tl'r.n'er Putting Out M.\chine. 



A recent machine of theirs which lias met with great success 

 is the Rubber Roll Putting Out Machine No. 156. a cut of which 

 we give herewith. In working this the skins to be struck out 

 are placed on a rubber roller which is lifted up by the mechanism 

 connected with the foot treadle as shown in the cut, and then 

 struck out by means of a felt roller and a brass bladed cylinder. 

 This machine has met with great success and over 100 ha\e been 

 sold during the twelve months it has been on the market. 



A MACHINE FOR ATTACHING EYELETS. 



Eyelets and grommets are used very extensively in cer- 

 tain lines of rubber manufacture. Footwear, clothing, sun- 

 dries and specialty manufac- 

 turers find them a necessity 

 ■for fasteningsand for thread- 

 ing. As a grommet is difficult 

 to attach successfully with- 

 out a grommeting machine, 

 it also follows that the rub- 

 ber manufacturers are the 

 possessors oi hundreds of 

 machines. They are simple 

 in the extreme, either to 

 operate or understand, and 

 are as useful as they are 

 simple. 



The Edwin B. Stimpson 

 Co., New York, makes the 

 automatic feed foot-power 

 eyeleter and grommeting 

 machine, which is shown in 

 the accompanying illustra- 

 tion. This company manu- 

 factures the grommets, eye- 

 lets and washers, and the 

 automatic machine for ap- 

 plying them. They, how- 

 ever, state that they do not 

 have on sale the machine 

 , _^^ that makes the grommets. but
