Abstract

843,555. Securing knobs on shafts. F.T. PRODUCTS Ltd. May 21, 1958 [June 3, 1957], No. 17587/57. Class 80 (2). [Also in Group XXV] A fastener, for releasably securing a moulded plastic knob 22 to a shaft 20 having a flat 21, comprises a C-shaped clip 12 which has a curved spring link 18 integral with a central web 13 and arcuate arms 14, 15 with inturned ends 16, 17 respectively. The knob 22 has a stop-bore 24 and a C-shaped central boss 23 with an external 'recess 26 having shoulders 27, 28. The clip 12 is pressed over the boss 23 so that the ends 16, 17 snap behind the shoulders 27, 28 and the limb 18 engages the flat end portions of the boss 23. The shaft 20 is then introduced into the bore 24, the limb 18 frictionally engaging the flat 21. In a modification the inturned ends 16, 17 of the clip are provided with a pair of out-turned prongs. A modified knob, Fig. 10, has a boss 33 comprising a major segmental section 34A formed on a radius slightly larger than that of the shaft 20 and a minor segmental section 34B formed on a larger radius.
