Abstract: A quick acting coupling device includes a male member 10 and a female member 32 with an axial opening for receiving the male member. A plurality of circumferentially spaced locking segments 50 are supported on the female member and move radially between an unlocked position and a locked position. A radially inward portion of each of the plurality of locking segments engages a locking groove on the male member when in the locked position, and rotation of the male member relative to the female member does not move the male member axially relative to the female member.

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.
