Abstract

536,785. Tripods; adjustments. KODAK, Ltd. March 1, 1940, No. 3848. Convention date, March 29, 1939. [Class 52 (iii)] Telescopic tripod legs 11, Fig. 1, are secured to a tripod head 10 by brackets 13 pivoted to lugs 14 by clamping bolts 15 and are formed of angular sections 12, 16, Fig. 2, frictionally clamped by lugs 20 fixed to the outer sections 16 and hinged at 26 to movable jaws 25 exerting pressure at the re-entrant angle 29 of the sections. The member 25 is actuated by a hollow bolt 32 having threaded engagement with the member 25 and provided at its respective ends with a flange 33 and cap-nut 35. The pairs of bolts 32 are oppositely threaded and are simultaneously rotated by a rod 37 with a hand grip 38 recessed at 40 to receive compression springs 39. The handle 38 also facilitates manipulation when adjusting the length by pulling out the sections.
