Abstract: A Universal Single Person Undermount Fixture Installation Device is sued for the installation of undermount style plumbing fixtures by a single installer. This device includes a support that is set atop the counter/substrate and spans the opening where the fixture is to be raised into its final position. This support includes an attachment that protrudes down through the opening and engages the fixture through the drain opening to allow it to be raised from above the countertop. This device also includes a method for final tightening of the fixture from above while in full view of its current alignment to the opening within the counter/substrate. The tool can be disengaged to release from the fixture drain opening once the fixture is fastened in accordance with the manufacturer's instructions.

Abstract: A prying tool comprises: a pry bar comprising a load tip at a distal end and a handle at a proximate end, the pry bar having a pair of pins extending on opposing sides thereof; a body through which the pry bar extends, the body forming a pair of pivot points for the respective pins, and a slot extending away from each of the pivot points; and a clamp that is attached to the body and configured for securing the prying tool by clamping a base of the body to a surface.

Abstract: A foldable clamp suitable for use in a mounting system is disclosed. In one embodiment, the foldable clamp comprises a base member, a first jaw, and a second jaw. The first jaw is connected to the base member using a first hinge. The second jaw is connected to the base member using a second hinge and a ratchet. A mount for selective interconnection is provided on either the first jaw, the second jaw, or the third jaw.

Abstract: A tool for loosening and/or unscrewing a screw in an object. The tool includes a frame dimensioned and configured to receive (or be mounted on) an object having at least one screw removably embedded therein.

Abstract: A bar clamp includes a handgrip; a fixed jaw carrier; a slide bar comprising two opposite wing members; a moveable jaw carrier and comprising a transverse channel, a trough extending from center of the channel to one end of the channel, a bottom recess, and two opposite stop members in the recess wherein the slide bar passes the channel with the wing members being stopped by the trough in a locked position; and a U-shaped spring-actuated lock assembly in the recess and comprising inverted U-shaped opposite first and second lock members being engaged with the wing members in the locked position, and first and second projections between the lock members and a bottom of the lock assembly and being engaged with the stop members in the locked position. Pushing the locking assembly until being stopped will disengage the lock members from the wing members.

Abstract: A single hand operated ratchet clamp comprises a finger ring lever and a typical ratchet clamp having a slide rail, a sliding arm, a fixed arm, and a lever element with pressure plate. The finger ring lever is pivoted to the free end of the lever element so that the ratchet clamp can be operated with one hand only.

Abstract: A clamp includes two handles pivotally connected to each other, a jaw pivotally connected to a short section of each of the handles and a device for positioning of the handles relative to each other. The positioning device includes a cylinder pivotally connected to a long section of one of the handles, a rack pivotally connected to a long section of the other handle and movably inserted in the cylinder, a detent pivotally connected to the cylinder for engagement with the rack to position the handles relative to each other, a lever comprising a first section pivotally connected to the cylinder and a second section operable to cause the first section of the lever to pivot the detent, and a spring compressed between the cylinder and the second section of the lever, thus tending to cause the first section of the lever to pivot the detent towards the rack.

Abstract: A single hand operated ratchet clamp comprises a finger ring lever and a typical ratchet clamp having a slide rail, a sliding arm, a fixed arm, and a lever element with pressure plate. The finger ring lever is pivoted to the free end of the lever element so that the ratchet clamp can be operated with one hand only. An alternate design is to make a finger hole on the free end of the lever element.

Abstract: Disclosed is a clamping device for securing and clamping work-piece quickly and efficiently. The clamping device includes an elongated slide bar; a first support assembly and a second support assembly. The first support assembly affixed at a proximal end portion of the elongated slide bar includes a first body portion, and a first clamping member. The second support assembly includes a second body portion, a second clamping member configured on the second body portion, and a locking mechanism configured on the second body portion. The second body portion is slidably coupled to the elongated slide bar for assuming a plurality of positions with respect to the first body portion. The first clamping member and the second clamping member are positioned in a spaced apart relationship for abuttingly clamping the work-piece there between to assume a clamped position of the plurality of positions.

Abstract: A bar clamp having a first jaw assembly, a second jaw assembly and a bar. The first and second jaw assemblies are mounted on the bar which is movable relative to the second jaw assembly. A trigger is operatively associated with the bar and is adapted to be activated to move the bar and the first jaw assembly relative to the second aw assembly in one direction. A release mechanism on the second jaw assembly is operatively associated with the bar and is adapted to be activated in order to permit the bar and the first jaw assembly to move relative to the second jaw assembly in the opposite direction.

Abstract: A hand-held clamp is described which is operable by one hand. The clamp includes a stationary jaw and a movable jaw carried on elongated support arms. A pressure arm is attached to the movable jaw and is advanced by a ratchet mechanism operated by the hand holding the clamp.

Abstract: A multi-element C-clamp has a workpiece gripping surface at a gripping arm on one end piece, and a rotatably advanceable gripping element supported from a cooperating gripping arm of a second end piece. A spring biased locking lever locks the end pieces in predetermined juxtaposition with respect to one another, with one non-gripping arm of one end piece inserted into a corresponding non-gripping hollow arm of the other end piece. Further increase in the gripping span of the C-clamp is obtained by interposing one or more lockable hollow extension pieces, nesting within one another intermediate the two end pieces, such that the C-clamp can be reduced to a compact unit when not in extended form for use. Slideable security latches are provided in the locking levers to ensure against accidental disengagement of extension or end pieces during use.

Abstract: A C-clamp arranged for operation by one hand, from a depending hand grip unit, to cause actuation of a ratchet assembly which quick-sets or closes the C-clamp on a work piece; the arrangement permitting of ready manual release of the C-clamp from the work piece.
