Abstract

495,207. Hinges; adjustable lamp supports. COOPER, H. C. May 29, 1937, No. 14963. [Class 65 (ii)] [Also in Group XI] A lamp holder 10, attached to a bracket plate 11 provided with a scoop-shaped arm 12, is connected to a supporting arm 13 by a joint consisting of a U-shaped member 14 which straddles the arm 12, and has extensions 19 which engage the supporting arm 13. Pivot pins 15, 20 attach the joint to the two arms 12, 13 of the fitting. The U-shaped member 14 and the extensions 19 may be formed from one piece of sheet metal or the extensions 19 may be provided by a separate U -shaped plate attached to the U-shaped member 14 by the pivot 15. Fig. 7 shows a modification in which two such U-shaped plates are provided and secured between one link of the U-shaped member 14 and a projection 29 of a supporting bracket 32. Spring washers may be employed on the pivot pins or the pivoting surfaces of the U-shaped member 14 and its extensions may be distorted so as to act in the manner of spring washers. The pivot pins may be tubular in form.
