Cyclopedia of heating, plumbing and sanitation; a complete reference work . k issubject to severe storms, it isfrequently necessary to guy thepoles even on straight such cases, the guys shouldextend from a point near the topof the pole to a point near thebutt of the a d j a cent guying should also beemployed at the terminal pole,the guy extending to a stubbeyond the last pole, to counter-act the strain of the wires pull-ing in the opposite direction. ()nparticularly heavy lines, it issometimes necessary to usestraight guys for the second andeven the third pole from the ter-minal pole, to prevent unduestrain on the terminal pole itself,as shown in Fig. 65. AMiere there are three ormore cross-arms, either two setsof guys should be employed, orelse a Y form of guy shouldbe used. If a single guy is usedon a long pole or on a pole car-rying a number of cross-arms, oron which there is unusual strain,the pole is apt to break wherethe guv is attached. Figs. 66 and67 show respectively a proper andan improper method of guying,and their 863 74 ELECTRIC WTRTNO At corners, or wherever the direction of the linework changes,guys should be provided to counteract the strain due to the change indirection. Guys are also necessary ;it points where poles arc set inother than a vertical position. Where the soil is not linn or solid, or where poles are subject tounusual stress, h is sometimes necessary to obtain additional stiffnessby what is known as crib-bracing, as may he seen from Fig. 68. Thisconsists of placing two short logs at the butt of the pole. Theselogs need not be more than 1 to 5 feel long, or more than 8 to 9 inches
