To all whom it may concern.- wire I), Fig. 2, is now out to such a length as Be it known that I, FRANK ALLEN, a citizen will permit its being Wound around the tube of the United States, residing at New York, in the proportion of about one convolution to in the borough of Brooklyn and State of New each lineal foot of the tube a, as shown in 55 York, have invented certain new and useful Fig. 3. Of course the wire may be previously Improvements in the Art of Manufacturing wound in helical shape, as shown in Fig. 2, Temperature-Equalizing Ooils, of which the and then placed over the tube a.

The wire should be of such heating or cooling purposes generally and thickness that it corresponds to one-half the which are especially applicable to ammonia difference between the internal diameter of andother refrigerating machines. the outer tube 0 and the external diameter of The object of the invention is to produce the inner tube a, or approximately so, so that 65 I5 such coils of the desired size quickly, conthe tubes can beplaced over one another, with veniently, and inexpensively. the wire serving as a separating medium, af- The invention consists of certain successive fording a neat fit and practically maintainsteps to be hereinafter described and then ing the concentricity of the tubes.

A suitable bending-machine is cle to be made. Fig. 2 is an elevation of a now used for the purpose of bending the sohelically-coiled wire which is to be placed assembled parts, causing them to assume the 75 over said tube. Fig. 3is an elevation of said shape shown in Fig. 5, with alternate bends tube wound with said wire. Fig. 4 is an elea at the ends of the straight portions.
