An elongated channel-shaped body is provided including a pair of opposite side longitudinal flanges and an elongated bight portion extending between and interconnecting one pair of corresponding longitudinal edge portions of the flanges. One of the flanges is rigid with and thus fixed relative to the bight portion and the other flange is pivotaly supported therefrom for oscillation about an axis extending longitudinally of the body along the adjacent marginal edges of the pivoted flange and the bight portion. The pivoted flange is oscillatable between a closed position with the adjacent sides of the flanges substantially parallel and an open position with the free longitudinal edge of the pivoted flange swung away from the free edge of the rigid flange. An elongated lever has one end pivotaly supported from one end of the bight portion on the side thereof remote from the flanges and an intermediate portion of the lever includes portions engageable with remote side surfaces of the longitudinal midportions of the flanges to cam the pivoted flange toward its closed position and to brace the rigid flange against flexure away from the pivoted flange. One end of the bight portion includes a structure defining a transversely extending and endwise outwardly opening channel for cradling a piece of lumber in the channel and the other end of the bight portion includes a transverse outwardly projecting abutment flange which may be utilized to support a wall board relative to a stud with which the clamp is clampingly engaged.
A lumber clamp comprising an elongated channel-shaped body including a pair of generally parallel opposite side longitudinal flanges and an elongated bight portion extending between one pair of corresponding longitudinal edge portions of said flanges, one of said flanges being rigidly supported from said bight portion and the other flange being pivotally supported from said bight portion for oscillation relative thereto about an axis extending longitudinally of said body and adjacent the adjacent marginal edges of said other flange and bight portion, for oscillation of said other flange between a closed position with the adjacent sides of said flanges substantially parallel and an open position with the free edge of said other flange remote from said bight portion swung away from the corresponding free edge of said one flange, and clamp actuator means shiftably supported from said body for movement between active and inactive positions and including portions engageable with said flanges intermediate their opposite ends for camming said other flange toward said closed position and bracing said one flange against flexure away from said other flange upon movement of said clamp actuator means to said active position, said clamp actuator means, when in said inactive position, being shifted to an out of the way position for movement of said other flange toward said open position.
A lumber clamp comprising an elongated channel shaped body including a pair of generally parallel opposite side longitudinal flanges and an elongated bight portion extending between one pair of corresponding longitudinal edge portions of said flanges, one of said flanges being rigidly supported from said bight portion and the other flange being pivotally supported from said bight portion for oscillation relative thereto about an axis extending longitudinally of said body and adjacent the adjacent marginal edges of said other flange and bight portion, for oscillation of said other flange between a closed position with the adjacent sides of said flanges substantially parallel and an open position with the free edge of said other flange remote from said bight portion away from the corresponding free edge of said one flange, and clamp actuator means shiftably supported from said body for movement between active and inactive positions and operative to swing said other flange toward said closed position upon movement of said clamp actuator means to said active position from said inactive position, said clamp actuator means, when in said inactive position, being inactive to prevent movement of said other flange toward said open position, the opposing inner surfaces of said flanges including outwardly projecting gripping elements adapted to penetrate at least the opposing surface portions of a piece of lumber clamped between said flanges.
