An improved wrench

1,213,378. Wrenches. P. H. WAGNER, [trading as P. H. WAGNER MASCHINENFABRIK]. 30 Oct., 1968 [2 Nov., 1967], No. 51366/68. Heading B3N. A socket wrench includes coaxial input, 4, and output 14 shafts, connected by a gear train which includes a pair of axially spaced gearwheels, 8, and that part of shaft 4 having teeth 15. The gear-wheels have planet gears 6 and 11; gears 6 are on pivots 22 which are welded at their ends to end plate 21 and ring 9 which is itself welded to gear 8; gears 11 are on pivots 10 which are welded via a ring 13 to output shaft 14. The planet gears are in mesh with teeth 20 on casing 1. Shaft 4 is axially movable so that extension 2 can engage a tubular member 3, this nullifies the action of the gear train and the whole wrench can then be rotated. In a modification, Fig. 4 (not shown), only one set of planet gears (6) are used in a smaller casing (36) where extension (18) of gear (8) acts as an output shaft. If the outer casing is to be locked during use a support (28) is attached to a hexagonal shaped portion (25) and a lever (30) inserted through bore (29) to engage any adjacent projection, Fig. 6 (not shown).
