A NEW WIKE COATIJIG AND SPOOLING MACHINE. 



/^NE of the principal difficulties that have been e.xpericnced 

 ^^ in machines for covering wire with insulating material 

 has been the removal of the surplus material by .neans of a 



time the wire has passed through the oven the insulation is 

 thoroughly baked on, and the coated wire then passes around 

 one of the pulleys M on the shaft T and back to the machine, 

 where it is wound on a spool A'. Any desired number of these 

 wind-up spools arc located on the uprights O 

 and driven by gears P. A reciprocating shuttle 

 W , operated by the screw-shaft Q, provides 

 a means of winding the wire evenly on the 

 spools. This shuttle bears a T-shaped bar R, 

 in which are a number of vertical pins 5 

 which guide the wires as they come from 

 pulleys M onto the wind-up spools. At the 

 top of the standards O is a conical speed pulley 

 )'. connected by a belt with a similar cone on 

 a countershaft (not shown). This pulley bears 

 a gear U and drives the screw-shaft Q through 

 the chain / ' and a set of bevel gears, by means 

 of which the snuttle is reversed in winding 

 up the coated wire on the spools. 



A New Wire Coating and Spooling Machine. 



wiping device, since such devices usually tend to "spot" the in- 

 sulation and thus prevent the use of such machines for perfectly 

 insulating very small wires. A new machine 

 designed for continuously and rapidly coating 

 a large number of wires simultaneously has 

 been patented by Myron D. Shiverick, of Al- 

 bany, New York. One of the features of 

 this machine is the new form of coating tip 

 and the method of supplying the coating 

 material to the tip. 



In the accompanying drawings Fig. 1 shows 

 a side elevation of the machine, Fig. 2 a plan 

 view, Fig. 3 a section through the dry- 

 ing oven, and Fig. 4 two views of the coat- 

 ing tip through which the wire passes. At- 

 tached to the frame A is a tank B which con- 

 tains the insulating material in liquid form. 

 The flow of this material to the coating tips 

 through the supply pipe C is controlled by a 

 stop-cock directly below the tank. The coat- 

 ing tips D are located side by side on the 

 horizontal pipe E, and any number of tips may 

 be employed according to the number of wires 

 to be coated. The uncoated wire is wound 

 on reels F , which are placed in uprights G, 

 the height of the frame being controlled by 

 the number of reels to be placed therein. At 

 H is shown a single wire passing under a 

 guide roller / and through the tip D, from 

 which point it is conveyed through one of 

 the holes / in the end of the oven. The oven 

 is heated in any suitable manner, such as 

 by a gas burner K, the wire being prevented from coming into 

 direct contact with the flame by means of a screen L. By the 



ANOTHER TIRE WRAPPING MACHINE. 



As a general rule machines adapted for 

 wrapping the treads of tires are designed for 

 that one purpose only, but the machine illus- 

 trated in the accompanying drawings and upon 

 which patents were recently granted, is de- 

 signed for wrapping and unwrapping tires 

 before and after the vulcanization process, 

 for wrapping tires for shipping purposes, for 

 removing the wrapper and also for cov- 

 ering wires and cables with paper, tape or
