•AtTTOPHoNIX' PNEUMATIC VULCANIZER. 



This new German vulcanizer consists of a special heating 

 appliance, which can be screwed on and used with any pneumatic 

 tire, whatever the measurement. Its application is very simple. 

 The damaged portion of the tire is cleaned and coated with 

 ".-Xutophonix Vulcanizer Solution," and then filled with 

 "Autophonix Vulcanizer Mass." The whole is then surrounded 

 with a small piece of fabric, and the apparatus screwed on, 

 being left for 20 minutes, until it has reached a temperature of 

 140 degs. C. (284 dcgs. F.), when the tire is again ready for use. 



NEW STYLE OF HOKIT BULB HOLD. 



The accompanying cut show-s an entirely new departure from 

 the old style rubber bulb mold. This type is said to be a distinct 

 innovation and is the first attempt in the nature of improvement 

 over the original. .-Xmong the advantages of the new mold — 



Tuij c .wnv H(iK.\' LluLii Molu. 



which, liy the way, is made by William Eggers & Sons, of 294 

 Taaflfc place, Brooklyn — is the small quantity of metal used in 

 its construction, which naturally means that it is very much 

 lighter and consequently more susceptible to heat, cools more 

 quickly, and therefore economizes time in vulcanization. The 

 cut shows a two cavity autohorn bulb mold, size No. 12, the 

 weight of which is only twenty pounds. These molds are used in 

 rubber factories, are said to have produced excellent results and 

 have been extensively patented by the makers. 



MOLD FOR STRETCHING AND VULCANIZING TIRES. 



In the manufacture of the ordinary type of pneumatic tire, 

 the fabric foundation of the tire casing is covered with the 

 raw rubber and placed under a uniform tension, which stretches 

 the fabric to approxi- 

 mately the limit of elon- 

 gation of the threads, 

 and the tire is vulcan- 

 ized while in this con- 

 dition. The accompany- 

 ing drawing shows a 

 new mold for accom- 

 plishing this purpose, the 

 invention of N. W. 

 McLeod, of St. Louis, 

 Missouri, on which 

 a patent was recently 

 granted in England. The 

 device comprises the hol- 

 low outer sections A, 

 connected by means of 

 the bolts B. The hol- 

 low core C is made in 

 sections and is secured to the ring D by the screws E. The 

 core is perforated so that steam admitted to the interior there- 

 of will act upon the inner surface of the tire casing F. It will 

 be seen that the space between the core and the outer section A 

 is greater than the cross section of the tire before vulcanization. 

 This allows sufficient clearance for expansion of the casing and 

 the stretching of the fabric when the bolts B are tightened. 

 Means are provided for introducing different -forms of tread 

 molds between the section A and the tire, one of these molds 

 being shown at G, with the apparatus ready for the introduction 

 of steam.
