Plumbers are often required to carry out various tasks on water pipes including measuring, cutting, bending, threading, joining, soldering and marking positions on pipes. Each of these activities requires the pipe to be held securely by the plumber (for instance in one hand, or under one foot, while the task itself is carried out using the free hand(s). The present invention is a tote tray provided with a clamp 15 connected to the open-top box, the clamp configured for releasably gripping a pipe 17. In this way, a plumber may place a pipe 17 within the clamp 15 and securely grip it therein, and may then carry out various types of work on the pipe 17 without the need to hold the pipe 17 manually in position. Once work on the pipe 17 has been completed, the user may release the clamp's grip on the pipe 17.

A cable clamping device includes a pair of grip jaws, a reset mechanism, and a handle connected to the grip jaws by the reset mechanism. The handle is pivotable about a handle pivot between a first position in which the grip jaws are in an open position and a second position in which the grip jaws are in a closed position around a cable. The reset mechanism pivots the handle from the second position to the first position before moving to a reset position of the reset mechanism that holds the handle in the first position.

A fixing device adapted to fix at least one needle-shaped member comprises a fixing base and a fixing mechanism. The fixing base has at least one positioning groove disposed at a front end of the fixing base. The needle-shaped member is adapted to be positioned in the positioning groove. The fixing mechanism has at least one pressing protrusion at a front end of the fixing mechanism. The pressing protrusion is adapted to press and hold the needle-shaped member in the positioning groove.

When coupling tubular parts by fitting, the seal interposed between them may roll on itself, be pinched or damaged. Now, a twisted or damaged seal no longer correctly ensures the seal-tightness and it is very difficult to detect this. The present application discloses a tool for installing a seal between two tubular parts, one male and one female, including a compression ring to encircle the male part and exert a compression on the seal before producing the join. The tool also includes a tongue that can be positioned at a chamfered surface of the female tubular part. The tongue makes it possible to offer the pre-compressed seal with the dimensions of the female part a continuous travel making it possible to prevent any twisting or other effect compromising the seal-tightness.

A method of manufacturing a cylindrical cargo container includes: providing a plurality of rigid panels together formable into a cylindrical shell; forming a first semi-cylindrical shell from a first set of the panels; forming a second semi-cylindrical shell from a second set of the panels; forming the cylindrical shell from the first semi-cylindrical shell and the second semi-cylindrical shell; forming a collar conformably encircling the cylindrical shell; constricting the collar to compress joints formed at abutting edges of pairs of adjacent panels; rolling the cylindrical shell and collar to bring respective joints of pairs of panels to a lower position, and welding an inside seam of the joint when at the lower position; removing the collar from the cylindrical shell; and rolling the cylindrical shell to bring respective joints of pairs of panels to an upper position, and welding an outside of the joint when at the upper position.

A frame block clamp includes first and second block portions dimensioned and configured to provide first and second tube receiving apertures for snugly receiving a predetermined tube; and to provide first and second “V” configured recesses in respective first and second side portions when portions of said first and second block portions are cooperatively engaged. The frame block clamp further includes a retaining spring dimensioned and disposed to urge together predetermined portions of the first and second block portions to ultimately secure a tube in the first or second receiving apertures. The frame block clamp is ultimately secured in a vise to allow a person to service the tube secured in the first or second receiving aperture.

A workpiece holder, which does not require actual parts matching as required in a related-art automatic pallet changer, and has higher maintainability than a related-art automatic pallet changer. The workpiece-side jig includes a workpiece-side fitting element provided on a surface opposed to the master-side jig. The master-side jig includes: a master-side fitting element to be fitted to the workpiece-side fitting element, which is provided on a surface opposed to the workpiece-side jig; a rotary pressing member to be brought into abutment against the workpiece-side fitting element fitted to the master-side fitting element to press the workpiece-side fitting element toward the master-side jig; and a rotational drive source configured to rotate the rotary pressing member. When the rotary pressing member is rotated by the rotational drive source, the rotary pressing member is brought into abutment against the workpiece-side fitting element to press the workpiece-side fitting element toward the master-side jig.

A clamping device includes first and second clamping components and at least one elastic component. The first clamping component includes a first rear portion and a first front portion pivoted to each other. The second clamping component includes a second rear portion and a second front portion pivoted to each other. The first and second rear portions are pivoted to each other. The elastic component connects the first and second clamping components. The first and second clamping components can rotate, with respect to each other, to a first state due to an elastic force of the elastic component so that the first and second front portions have a first distance. When the first and second clamping components are subject to a force, the first and second clamping components resist the elastic force of the elastic component and rotate, with respect to each other, to a second state so that the first and second front portions have a second distance greater than the first distance.

A stabilization clamp for stabilizing and holding fire hydrants or other vertical members, riser pipes, etc., during installation. The stabilization clamp includes a pair of jaws (or other means for holding a vertical member) adapted to securely hold a vertical member, a pivot assembly having a first end and a second end and a pivot between the first end and the second end, the pivot assembly being connected to the jaws at the first end and to a pair of legs at a second end, and an anchor attached to a distal end of each leg. The legs are positionable such that when the distal ends of the legs are spaced apart from each other and anchored, the pivot assembly causes the jaws to close and hold the vertical member in a fixed position.

At least some implementations of the present invention include the ability to access and secure a compressed riser portion of a pop-up sprinkler. Access is gained through use of the tip of the tool, sloped for access clearance between the sprinkler nozzle lip and outer sprinkler base. Once raised from the outer sprinkler casing, the riser is secured in a designated clamping bay or within designated clamping points. This two-pronged approach accommodates varying diameter of sprinkler risers and increases the multi-use function of the tool. The tool's overall inward tension is provided by an engineered compression spring designed with adequate outward tension without making hand compression use of the tool restrictive. Use of the tool in an inward sweeping motion toward the sprinkler allows for raising and clamping the riser in a quick and simple fashion. Thereafter, allowing free and open-hand access for quick and thorough maintenance, repair, exchange or adjustment of the sprinkler nozzle and filter.
