332 The Farmstead 



The insulator shown is manufactured by the 

 General Electric Company, of Schenectady, New 

 York, and similar ones are made by other man- 

 ufacturers of electrical materials. 



In order to attract the discharge, the rods 

 must project some distance above the roof, 

 about 6 feet being the proper height. This 

 projection must be supported, and there are two 

 ways to do this. The first is to screw or nail 

 a piece of timber to the side of the building, 

 projecting about 5 feet above the roof. Two 

 insulators on this will provide the necessary 

 support for the rod. As this might be con- 

 sidered unsightly in some places, a neater but 

 more expensive method is to use a piece of 

 %-inch copper, brass or iron rod for the upper 

 9 or 10 feet of the rod. This can be easily joined 

 and soldered to the copper ribbon and is strong 

 enough to support itself in any wind. A brace 

 from the vertical to the horizontal rod will pro- 

 vide additional support if desired, and will give 

 a more substantial appearance. At the point at 

 which the horizontal rod passes through a tim- 

 ber support, in case such plan is used, a hole 

 1% inches should be bored in the timber to avoid 

 any risk of its being burned. In joining the 

 horizontal to the vertical rod, the former should 

 be bent up at right angles for an inch, and the 

 surfaces should then be well cleaned and soldered.
