Abstract
A clamp mechanism (20) having a pair of jaws (22, 23) cooperating with a pair of threaded rods (24, 25) that displace equally from a midpoint (36) of mechanism (20) along threaded rods (24, 25) by means of a spirally-wound rod (40) with sets (41, 42) of keyways riding in sets (50, 51) of keys positioned in jaws (22, 23). A center 20. Sliding assemblies (60, 94) lock and unlock barrel nuts (71, etc.) in the jaws from threaded rods (24, 25). Different senses of threads for threaded rods (24, 25) extend to each side of rod 40. In another embodiment, a push handle (116) directly actuates the ‘quarter-turn’ threads in bores (122) of barrel nuts (115) into and out of engagement with threaded rods (121).
Claims21
A clamp mechanism including a pair of jaws and threaded rod members extending through said jaws,
- barrel nut means rotatably mounted in each of said jaws, said barrel nut means including body formations forming bores and on which ‘quarter-turn’ means are formed in the bores, and
- assembly means slidably mounted to said jaws for actuating means for locking and unlocking said barrel nut means to said threaded rod members through engagement and disengagement of said ‘quarter-turn’ means with said threaded rod members.
A clamp mechanism including a pair of jaws and threaded rod members extending through said jaws, said jaws including conical-like slots,
- barrel nut means rotatably mounted in each of said jaws, said barrel nut means including body formations forming bores and on which ‘quarter-turn’ means are formed in the bores,
- means for maintaining equality of opening and closing from a midpoint in said clamp mechanism for said pair of jaws from and to one another along said threaded rod members, and
- means for actuating said barrel nut means to engage and disengage said jaws with and from said threaded rod members.
