Abstract

654,893. Hinges. WEBLEY & SCOTT, Ltd., and SMALLWOOD, H. W. Aug. 7, 1948, No. 20884. Addition to 630,391. [Class 65(ii)] [Also in Group XXVI] An electric fan as claimed in the parent Specification comprises a fan guard and vane assembly in which aligned forks arranged on the guard locate and retain bearing pins supported in the ends of the vanes. Forked lugs 30, Fig. 4, are formed integral with a die-cast guard 3b. Each vane 4 has a socketed end 25 into which a bearing ball 26 is inserted as a push fit. A bearing pin 27 is inserted in a lug 30 and retained by pinching in the tips of the lug about a reduced portion 28. Each vane 4 is connected to a coupling rod 6<1>, Figs. 6 and 7, by means of a pin 34 which is received in a recess 33 and retained by pinching inwardly the margins 35 of the recess. Specifications 451,597, [Group XXVI], and 497,683 are referred to.
