A rough repair may be made by trimming back the broken ends, overlapping them as in Fig. 1.22,

and fastening them with two or three cable clamps, for sizes up to ⁄ 8 or ⁄ 2 inch, or with three or more
for larger sizes. Or two interlocked loops may be made, as in (B), fastened with clamps or any type
of loop fastening. Cables repaired in this manner are weakened but may last a long time. The patch
will not go through pulleys and is inconvenient in other ways.
Winches on Wheel Tractors. If a winch is mounted on a wheel tractor or truck, it is usually nec-
essary to anchor it for heavy pulls. The anchor chain or cable should be attached to the winch
frame, or to a heavy member as near to it as possible, to reduce strain on the tractor.
An important consideration in the use of these winches is the fact that the cable will tend to
take a straight line between the work and the anchor. In making a high pull, as in Fig. 1.23(A), the
