A multi-model pipe joint connection device, which includes a main body, a pipe body clamping mechanism located on one side of the main body for clamping the pipe body, a supporting part with an internal space, a joint positioning fixture that can be detachably assembled in the internal space and used for clamping the joint, and a power part located on the other side of the main body. The power part is capable of driving the supporting part towards the pipe body clamping mechanism, enabling the joint clamped within the joint positioning fixture to connect to the end of the pipe body held by the pipe body clamping mechanism. The invention employs the pipe body clamping mechanism and joint positioning fixture to achieve quick positioning of the pipe body and joint, respectively, and uses the power part to enable the positioned joint to enter the positioned pipe body.

A centerline clamp assembly sized to insert into an end aperture of a pipe structure, characterized by two or more symmetrically-formed linkages interoperably connected in series, with each of these linkages comprising respective opposing toggle joints pivotally joined at their inner ends to a shared common linkage assembly and at their outer ends by a respective first linkage assembly and a second linkage assembly, with each linkage assembly defining a respective bore configured to concurrently receive an actuating shaft in position along a common geometric centerline axis of the pipe. Multiple alternative configurations may be used in which the number of linkages and linkage assemblies may be increased to achieve clamping action at multiple locations in a pipe structure, thus varying the clamping force according to the properties of the pipe. The configuration and number of linkage assemblies may serve as mounting platforms for instruments, tools, and/or accessories.

A segmented wood bracing assembly includes a base that has an upper surface a first lateral edge and a second lateral edge. A pair of rails is attached to the base and extends between the first and second lateral edges. Each of a plurality of cradles receives a plurality of wood sections to be glued together into a polygonal shape. The cradles include a receiver having a top side, a first side edge and a second side edge. The top side has a convexly arcuate section for receiving the wood sections. Each of the first and second side edges has one of a pair of clamps mounted thereon. A strap has a first end and a second end. Each of the first and second ends is removably engaged to one of the clamps. The clamps is actuated to locked position to tighten the strap over the top side.

A method for assembling a ball valve using a system having a support structure and a tool includes positioning a body of the ball valve on a surface of the support structure. The method also includes driving one or more engaging members of the tool radially outward from a retracted position to an expanded position to engage a seat disposed within the body of the ball valve. The method further includes adjusting an axial position of the surface of the support structure relative to the one or more engaging members of the tool while the seat is engaged by the one or more engaging members of the tool to drive the seat into a seated position within the body of the ball valve.

A plug for closing a hose connector termination includes a hollow cylindrical body closed by a rounded end portion and open at the opposite end. The plug comprises tensioned fibrous material that extends in a continuous manner across the width of the rounded end and to the sides of the body.

A pipe alignment tool for aligning abutted ends of first and second pipe sections to be joined includes a clamp member adapted to be clamped circumferentially about the first pipe section and one or more pipe engaging members mounted on the clamp member adapted to extend across a seam between the abutted ends of the first and second pipe sections to overlap the second pipe section. A bearing member is rotatably supported on each pipe engaging member for rolling contact with the second pipe section to assist in positioning the second pipe section relative to the first pipe section. The clamp member may be formed of modular sections connected circumferentially in series in which each modular section defines a mounting location upon which a pipe engaging member can be removably attached.

A first aspect of the invention provides for a fixture for securing a component to be drilled. The fixture may comprise: a support structure positioning the component thereon; a template substantially surrounding the component configured to locate a position on the component that is to be drilled, the template being positioned on the support structure and having at least one hole therethrough; and a centering device positioned on the support structure configured to center the component within the template.

A rafter angle square door clamp stand system functions like a truss, utilizing tension and compression. A horizontal tension base is suspended off of the ground by rotatable support members, one at each end of the base. The tension base has a T shaped slot that runs the length of the base. Two rafter angle squares, each having a T shaped member, slide into the slot of the base, one from each end of the base, with the vertical edges of the angle squares facing each other. The weight of the door on the tension base causes the base to flex downward, and the rafter squares to compress, holding the door in an upright position. Stop elements prevent the angle squares from moving backwards when the door is compressed and clamped. The system can be converted to support cylindrical objects, by reversing the positions of the angle squares.

A multi-functional clamping device is disclosed. The multi-functional clamping device includes a handle portion having a vice grip handle, and a clamping portion coupled to the handle portion. The clamping portion includes opposing clamps. The multi-functional clamping device also includes an accessory mount coupled to the clamping portion. The position of the accessory mount is adjustable or non-adjustable with respect to the clamping portion. Further, the multi-functional clamping device includes an accessory locking fixture coupled to the accessory mount.

An alignment device is configured to receive, in a generally aligned configuration, workpieces which are to be joined together. In addition, the device is further configured such that, in use of the device, a joining line between the two workpieces is visible for checking alignment, and such that, in use of the device, each workpiece can be marked at a predetermined distance from the joining line. The device and a method of alignment using the device are particularly suited to the joining of pipes in the construction of marine vessels.
