Abstract
An improved workbench includes collapsible legs, tool holders attachable to the legs, extensible auxiliary support legs, a generally planar bench top with a removable section for power tools and a pair of adjustable vises cooperative with the planar top. The adjustable vises include a mechanism for gross and fine adjustment and additionally include gripping jaws that are pivotal.
Claims19
An improved workbench comprising, in combination:
- (a) a top with a side edge rail;
- (b) collapsible legs attached to and supporting the top;
- (c) a vise member affixed to the top, said vise member including a gripping jaw in opposed relation to the side rail of the top, said vise member also including means for separately adjusting the spacing of the attached gripping jaw from the side rail;
- said means for adjusting including three slidably telescoped members, mounted for telescopic movement transversely with respect to the side edge rail;
- the outside member connected to the gripping jaw, the middle member including adjustable ratchet means for engaging cooperative means attached to the bench and thereby providing means for gross adjustment of the gripping head with respect to the side rail, the inside member including means for simultaneous movement with the outside member with respect to the middle member to thereby provide fine adjustment of the gripping jaw or release of the ratchet means.

An improved workbench vise comprising in combination:
- (a) fixed side member including a fixed jaw;
- (b) a movable gripping jaw cooperatively attached to the fixed side member in opposed relation to the fixed jaw;
- and
- (c) means for separately adjusting the spacing of the movable jaw from the fixed jaw, said means for adjusting including three slidably telescoped members mounted for telescopic movement transversely with respect to the fixed jaw;
- the outside member being connected to the movable jaw, the middle member including adjustable ratchet means for engaging cooperative means attached to the fixed jaw and thereby provide gross adjustment of the movable jaw with respect to the fixed jaw, the inside member including means for simultaneously adjusting the longitudinal position of the inside and outside member with respect to the middle member to provide fine adjustment of the gripping head.

An improved workbench comprising, in combination:
- (a) a top with a side edge rail;
- (b) leg members attached to the top in support thereof;
- and
- (c) at least one vise member attached to the top, said vise member including a movable gripping jaw in opposed relation to the side edge rail, said vise member also including a fixed support tube attached to the top cooperative with three telescoping tubes connected to the gripping jaw, said tubes having means for a gross adjustment and means for a fine adjustment of the position of the gripping jaw with respect to the side edge rail, said means for gross adjustment comprising a ratchet and pawl mechanism with means to render the ratchet and pawl mechanism inoperative by telescopic movement of the tubes relative to each other.

An improved workbench comprising, in combination:
- (a) a top with a side edge rail;
- (b) leg members attached to the top in support thereof;
- and
- (c) at least one vise member attached to the top, said vise member including a movable gripping jaw in opposed relation to the side edge rail, said vise member also including a fixed support tube attached to the top cooperative with three telescoping tubes connected to the gripping jaw and having means for a gross adjustment and means for a fine adjustment of the position of the gripping jaw with respect to the side edge rail, said means for fine adjustment comprising a rigid connection between the inner and outer tubes, said gripping head being connected to one of said tubes, and an adjustable connection between the middle tube and the inner tube and outer tube, said adjustable connection including means for simultaneous movement of the inner and outer tubes with respect to the middle tube.

An improved workbench comprising, in combination:
- (a) a top with a side edge rail;
- (b) leg members attached to the top in support thereof;
- and
- (c) at least one vise member attached to the top, said vise member including a movable gripping jaw in opposed relation to the side edge rail, said vise member also including a fixed support tube attached to the top cooperative with three telescoping tubes connected to the gripping jaw and having means for a gross adjustment and means for a fine adjustment of the position of the gripping jaw with respect to the side edge rail, said means for gross adjustment comprising a pawl mechanism with means rendered inoperative by telescopic movement of one of the tubes relative to the other two, said means rendering the gross adjustment inoperative including a driving section of one of the tubes engaged with the pawl mechanism to prevent operation of the pawl.
