[June i, 1909. 



NEW FACTORY APPLIANCES. 



A WIRE INSULATING MACHINE. 



AMACHIXE for insulating wire recently invented by Frank 

 D. Flatter, who has assigned his to the Western Electric 

 Co., is shown in the accompanying illustration. Briefly described, 

 it shows a frame on which is a cop carrier rotatably supported 

 and arranged to wind the insulating thread upon the wire. There 

 is also a mechanism for driving both the cop carrier and for

feeding the wire; a magnet mechanism for stopping the driving 

 mechanism, an insulated contact piece with which the wire en- 

 gages after passing the cop carrier, a circuit for the magnet 

 including a source of current, and having its opposite terminals 

 connected respectively with the contact piece and the frame of 

 the machine. The United States patent is No. 918.590. 



CONTINUOUS VULCANIZATION. 



A NEW suggestion in continuous vulcaniEation is shown in the 

 accompanying illustraticn. It is a vulcanizer for curing long 

 strips, belts or rods. It is really a series of steam pipes, coupled

end to end, standing roughly in the form of the letter W. Above 

 each end is a roll over which the strip to be vulcanized passes. 

 There are also three rollers, one in each curve. The strip to be 



vulcanized is led into the pipe under the first bottom roll, up 

 and over the top roll, then down under the second bottom roll, 

 up again, and out. During this process steam is let into the two 

 central pipes and prevented from escaping by "mercury or other 

 liquid seals." A British patent (No. 26,627 — 1907) has been 

 granted to W. D. Gratama, Rijswijk, Holland. 



VULCANIZING HOSE IN CONTINUOUS LENGTHS. 



Another ingenious and yet simple machine for making hose 

 in continuous lengths has been patented by John Gammeter and 

 assigned to The B. F. Goodrich Co. As will be seen from the 

 illustration, the machine consists in the main of a hollow vul-

canizer, open at both ends, through which the hose is led. At 

 either end are bobbins and coiling dies, so arranged that the 

 hose is wrapped before entering the curing chamber and un- 

 wrapped as it comes out. This process is continuous. The 

 patent is numbered 913,720. 



BEVELING PNEUMATIC TIHE TUBES. 



A SIMPLE and effective machine for beveling inner tubes for 

 pneumatic tires is shown in the accompanying illustration. It 

 consists briefly of a shaft upon which the tube casing is

mounted, and means for transmitting rotary motion to the 

 shaft, and the proper slanting motion to an angle knife whereby 

 the end of the tube is skived or beveled. This is an invention 

 by Andre Olier, of Clermont-Ferrand, France. The United 

 States patent is No. 918,360.
