The heater consists ofa piece ot^>4-in. iron pipe, bent in a continuous double heli-cal coil, with spacing blocks to keep the pipes in the rightposition and Uie right distance from the tire. It is impor-tant that the latter distance so adjusted that the hottestpoint of the flame is at the tire. The first section of thecoil has no small holes in it and merely acts as the pre-heater The second section, which goes next to the tire flange,is provided with a continuous row of 1/16-in. holes drilled?y; in apart. The usual form of oil container and vapor-izer is then connected to the shop air line and to the tireheater bv a hose connection. , , , ., *^ This form of tire heater has proved to be both easy tostart and economical in the use of oil. It is possible toobtain a good blue flame with kerosene, and by inaking coilsof suitable diameters any size of tire can be heated m a satis-factory- manner. How Jim
