Abstract

820,094. Securing knobs on shafts. ROBERTSHAW-FULTON CONTROLS CO. July 22, 1957 [Aug. 2, 1956], No. 23182/57. Class 80 (2). [Also in Group XXIX] The temperature-setting rod 114 of a thermally-actuated valve screws through a casing 10 at 116 and has a tapered flange 118 on which an abutment ring 120 with projection 126 is clamped by a nut 122 screwing on the end of rod 114. The operating dial 124 slips over the nut and mates with the projection and presses on casing friction pads 135 under the action of spring 134 between the dial and a screw head 132. On rotating rod 114, the screw head compresses the spring as the rod moves axially through the dial and casing.
