Abstract
3191. Curtis, A. H., and Adams Manufacturing Co. Feb. 9. Resistances. - A thin flat strip or a woven or braided tape E of resistant material is wound over radial projections on insulated heads C, the flat sides of the strips &c. being radially disposed to facilitate cooling. The heads Care adjustably carried by a central rod A, one or both of the heads being supported on compression springs D so as to stretch the resistance-material E. The heads C may be of metal insulated from the resistance-material, for example by mica strips G, which may be secured by metal strips ; or the heads may be of porcelain or of metal supporting a porcelain top. The radial arms may be formed by pins screwed into the head and carrying insulating bushes, an encircling clip holding these in place. The heads may be adjusted by nuts B which may be turned simultaneously on right- and left-banded screws by a tube fitting both nuts, or by a bar having pins at each end which engage slots in the nuts B. The radial arms may be increased in length to carry more than one convolution of resistant material.
