Abstract

667,681. Hand contactappliances. HUGHES & CO., Ltd., F. A. March 3, 1950 [April 7, 1949], No. 9486/49. Class 38 (i). A contact device suitable for pushing into contact with buried metal, comprises a tube 1, enclosing a rod 5 with a contact point 9 which can be withdrawn within the tube or propelled out of it by relative movement between a threaded plug 17 on the rod and a threaded portion 14 of the tube. The plug 17 may be provided with a socket for a plug connected to a measuring instrument. The point 9 is preferably a gramophone needle secured by a grub screw 12. The tube and the rod shown are in two parts coupled respectively at an enlargement 4 and by a sleeve 8.
