Abstract

237,023. Barber, G., and Hough, T. April 23, 1924. No Patent granted (Sealing fee not paid). Wireless tuning-apparatus, adjustment devices for.-An improved knob and dial attachment for variometers, condensers and other electrical instruments comprises a brass or other sleeve d secured to the dial b and provided at its upper end with a screw-threaded hole for the reception of a grub screw e, the outer end of which projects into a vertical slot g in a circular aperture in the knob a. An aperture f in the knob allows the insertion of a screwdriver when the position of the. knob and dial on the spindle c of the instrument is being adjusted.
