Abstract: A torque applying tool (10) having a housing or body (14) including a rectangular body portion (16) having a worm receiving opening (20) extending therethrough and an arcuate housing portion (18) having a gear receiving opening (22) extending therethrough at right angles to the worm receiving opening (20). A toothed gear (26) is mounted within gear receiving opening (22) and has a central opening (32) of a hexagonal shape to receive nut (N) therein to be rotated. Worm gear (38) is received within worm receiving opening (20) and has a helical thread (39) thereon formed of a concave shape to engage teeth (28) on gear (26) for rotation of gear (26) and nut (N).

Abstract: A spreader tool (10) and method for spreading apart a pair of opposed parts (F) comprising a housing (12) having a central bore (18) with a piston (42) mounted therein for reciprocal movement. The lower end of the piston (42) has a center spreader member (45) secured thereto and fitting between a pair of side spreader members (30, 32). Upon actuation of the cylinder (42) the center spreader member (45) moves in a parallel relation to the adjacent side spreader members (30, 32) for spreading the members (F) apart. The tool (12, 12A) may be manually actuated by a ratchet handle (66) as shown in the embodiment of FIGS. 1-3, or may be hydraulically actuated by pressurized hydraulic fluid from a pump (P) as shown in the embodiment of FIGS. 4-6.
