Abstract: A toothpaste tube squeezer has first and second squeezing blocks for holding a toothpaste tube therebetween. A first clamping mechanism is positioned toward an opening end of the toothpaste tube to apply pressure to the first and second squeezing blocks to squeeze the toothpaste tube. A second clamping mechanism is positioned toward a sealed end of the toothpaste tube to release pressure on the blocks. Both squeezing blocks may have slightly outwardly curved surfaces to contact the toothpaste tube. As the second clamping mechanism is loosened to release pressure applied at the sealed end of the toothpaste tube, a gap may increase between the squeezing blocks at the sealed end of the toothpaste tube. Due to the slightly curved surfaces of the squeezing blocks and the increasing gap, a squeezing pressure moves further up the toothpaste tube in a direction from the sealed end to the opening end.

Abstract: A seal clamp assembly for sealing an opening in a piping system includes, in an exemplary embodiment, a base having a first side, a second side and an aperture extending therethrough from the first side to the second side, and a brace coupled to the base. The brace includes a distal pad hingedly coupled to a distal end portion of the brace. The seal clamp assembly also includes a spring bridge coupled to the base first side. The bridge includes a substantially rectangular U-shaped frame and an aperture extending through the spring bridge frame such that the spring bridge aperture is in substantial lineal alignment with the base aperture. A clamping assembly is coupled to a proximate end portion of the brace.

Engagement portions on the tools are clamped by the clamping blocks comprising a connector assembly; the tools may be C-clamps, bar-clamps, pipe-clamps, coupling devices, brackets, standoffs, and like implements.

Abstract: An interior c-clamp's holding-device (10), for repairing cracks in violins without removing the soundboard (18) (top of the violin), comprising a housing (15) located at the bottom-end of a c-clamp (21). The housing (15) has both a horizontal and a vertical passage bored through the housing (15) creating an intersection inside the housing (15) where the two bores meet.

Abstract: In accordance with the present invention, there is provided a riveting device. The riveting device is provided with a body defined by a body longitudinal axis and having a pressure port formed therein. The riveting device is further provided with a jaw defined by a jaw plane. The jaw has first and second jaw extensions with the first jaw extension having a jaw plunger orifice extending therethrough. The riveting device is further provided with an angular attachment having an attachment plunger orifice extending therethrough. The angular attachment is attached to the first jaw extension with the attachment plunger orifice being axially aligned with the jaw plunger orifice. The angular attachment is further attached to the body and formed to maintain the jaw plane at an angular orientation relative to the body longitudinal axis. The riveting device is further provided with a rivet plunger having opposing rivet and base ends.

Abstract: An apparatus for moving a movable assembly along a mast is provided. The movable assembly has a bore adapted to receive the mast passing through it. The movable assembly has a release and retain mechanism; a uni-directional drive mechanism; and a switching mechanism for engaging the uni-directional drive mechanism. The switching mechanism has a shaft positioned within the movable assembly, generally oriented parallel to the bore, that is capable of rotational movement around the longitudinal axis of the shaft and axial movement along the longitudinal axis of the shaft. The switching mechanism also has a drive pin attached to the shaft of the switching mechanism that is oriented generally perpendicular to the longitudinal axis of the shaft. The switching mechanism also has a mechanism for affecting the axial movement of the shaft that is preferably in the form of a cam. The release and retain mechanism has a biased release lever defining a slot that is sized to receive the mast.

Abstract: A clamping tool, in particular a screw clamp (1) having a fixed bracket (3), which provides a clamping surface (4) and is fixedly connected to a slide rail (2) on which a sliding bracket (5) is seated such that it can be displaced and secured, and having a counter clamping surface (8) which, by a clamping element (7), can be braced against a workpiece which can be clamped between the clamping surface (4) and the counter clamping surface (8), the eyelet (6) of the sliding bracket (5) being secured against slipping with respect to the profiled slide rail (2). A latching body (13) which is associated with the sliding bracket (5), projects into the eyelet (6), and is capable of yielding resiliently for cooperation with a latching profiling (10) of the slide rail (2).

Abstract: A hand tool or clamp, capable of clamping a work-piece of any size within a wide range of sizes, includes a fixed jaw secured to one end of a slide bar, the other end of which is received in an elongate hollow sleeve and supported for back and forth movement relative to the sleeve. A movable jaw is supported on said sleeve at a selected one of plural mounting locations spaced along the length of the sleeve, each defined by a transverse pin extending through the sleeve. Once the fixed jaw has been advanced by hand toward the movable jaw sufficiently to clamp the work-piece, the sleeve and slide bar are releasably locked together by a pawl and ratchet mechanism. The clamping pressure is increased over that provided by hand by a screw mechanism associated with the fixed jaw.

Abstract: A corner clamp joining a pair of generally orthogonal elongated members is formed by slicing a generally C-shaped frame form an aluminum alloy extrusion so that the frame includes a member spanning opening with a pressure pad defining one extremity of the opening and an opposite opening extremity face including a threaded hole and a threaded shaft passing through the threaded hole and helically movable therein toward and away from the pressure pad. The members are joined by clamping them together between the pressure pad and the end of the movable shaft. One elongated member may be an I-beam and the other a U-shaped channel with the U opening away from the I-beam. The slice is taken obliquely to the direction of elongation of the extrusion so that the pressure pad has a non-rectangular generally parallelogram shaped face. When assembled, one edge of the pressure pad face extends generally parallel and adjacent to an inner U surface.

Abstract: A locking, three-way clamp for applying a bi-directional vector force against one or more workpieces. The clamp 10, of the present invention, includes a handle 22, first and second opposing jaws 24 and 26, respectively, a jaw actuation lever 28, a threaded adjusting screw 30 and a toggle lock 32. Second opposing jaw 26 pivots, in relation to first jaw 24, about a central pivot point 34. First and second opposing jaws 24 and 26 each include a distal end 25 and 27, respectively. A workpiece restraint member 36 can be utilized for providing a rigid planar surface for engagement with a workpiece. The locking three-way clamp 10 of the present invention also includes an engagement device 50, on the distal end of each jaw, that pivots inward towards the restraint member 36 thus applying a vector force having x- and y-component vectors that forces a first workpiece against a second workpiece and simultaneously forcing the clamp 10 towards the workpieces 120 and 140.

Abstract: A C-clamp device has a blocking bar detachably secured to the upper pad to prevent rotation of the pad and has a swivel pad on the lower anvil means for engagement with the clamped article.

Abstract: A clamp useful for firmly securing a camper housing within the bed of a pickup truck which allows for efficient attachment or removal of the camper housing. The device includes a U-shaped clamp body having a pivotal connector at one end that is affixed to the camper housing and a reciprocally movable, spring biased arm having a roller at its free end such that the roller engages the lip of the pickup truck bed to permit pivotal movement over center to effect spring locking action of the clamp. The device allows a camper housing to be readily installed or removed from a vehicle bed by manual actuation of the holding clamps.
