    Abstract: A tool adapted to install and remove strainer basket assemblies. The tool has a tubular main body that incorporates a means for gripping the upper strainer nut on a strainer basket assembly. The tool also has a moveable shaft that incorporates a means for gripping a strainer basket assembly. The tool is used to assemble a strainer basket assembly by attaching the tool's upper strainer nut gripping means to a upper strainer nut, attaching the tool's strainer basket gripping means to a strainer basket assembly, and applying a force to the tubular main body and an opposing force to the moveable shaft to tighten the upper strainer nut. The tool is used to disassemble and remove a previously installed strainer basket assembly by attaching the tool's upper strainer nut gripping means to an upper strainer nut, attaching the strainer basket gripping means to a strainer basket assembly, and applying a force to the tubular main body and an opposing force to the moveable shaft to loosen the upper strainer nut.

  • Patent number: 6000301
    Abstract: An adjustable wrench utilizes a drive member housed in a wrench body. The drive member has a cylindrical drive element having external male threads formed thereon, onto which a guide block is mounted by means of a bore, within which female threads, complementary to the male threads, are formed extending longitudinally through the guide block, so that the drive element extends through the bore with the male and female threads in engagement with one another, whereby rotation of the drive element is operable to move the guide block longitudinally along the drive element. A drive knob is fixed to and manually operable for selectively rotating the drive element. A pair of alignment arms connect a movable jaw element to the guide block so that the movable jaw element faces and is displaced from the drive block in longitudinal alignment with the bore and is separated from the drive knob by the drive block.

  • Patent number: 5862722
    Abstract: An adjustable wrench has a slotted body member and a handle threaded into a bore in a body member stem and protruding into one end of the slot. A movable jaw piece is rotatably mounted to the protruding handle end and slidable in the slot. A pair of angled fixed jaw faces is formed at the far end of the slot, while corresponding jaw faces are formed on the movable jaw piece. Relative rotation of the handle and body member causes relative advance or retraction of the movable jaw piece in the slot to adjust the spacing between the sets of jaw faces to fit the wrench to bolt heads or nuts of various sizes. The structural support afforded by the handle-movable jaw piece connection enables low cost construction and compact structure allowing greater accessibility to recessed bolt heads and nuts. A locking rod extends within the handle in some embodiments, with a locking knob at the remote handle able to be tightened to hold an adjusted position.

  • Patent number: 5428853
    Abstract: A fireman's personal hand tool is comprised of a spike member and a wrench member. Both members may be used in combination as a slide hammer with the spike member being hammered by the wrench member between objects to be pried apart. The wrench member may also be used to open or close valves and is configured to fit a variety of hydrant valve head shapes and sizes. Both the spike member and the wrench member have integral hose coupling jaws to engage and disengage hose couplings. The members are separable so that the jaws may be used independently or in combination. In addition, there are three different sizes of jaws to enable the tool to fit a greater variety of coupling sizes.

  • Patent number: 4967613
    Abstract: The subject invention relates to the art of adjustable wrenches. The adjustable wrench of this invention is particularly suited for the gripping of hex head fasteners. The adjustable wrench has a handle portion and a head portion. The head portion has two downwardly extending jaws. One jaw is stationery, the other being moveable. The moveable jaw moves in an elongated slot which is integral with the head portion. The moveable jaw and the elongated slot incorporate opposing interlocking surfaces which cooperate in such a manner as to support the moveable jaw during usage. The moveable jaw is connected to an adjusting means which may be an adjusting screw and an adjusting nut. The adjusting means controls the fixed relationship between the moveable jaw and the fixed jaw. In the embodiment which utilizes an adjusting screw its movement and hence the movement of the moveable jaw is controlled by the rotation of an adjusting nut.

  • Patent number: 4781086
    Abstract: An adjustable wrench particularly useful to facilitate ease of installation and removal of fluid fittings in and from a fluid system. The wrench includes an elongated handle threadedly cooperating with a body member. The body member has a pair of opposed clamping faces defining a clamping cavity adapted to receive an associated fitting. Relative rotation between the handle and body portion axially advances and retracts a smooth end face of the handle into and out of abutting engagement with a side wall of the fitting. A cutout region in the wrench body is adapted to receive one branch of an associated tee or cross type fluid fitting. The subject wrench readily facilitates clamping engagement of a fitting while coupling nuts are run up on or backed off of the fitting branches by conventional means.

  • Patent number: 4549324
    Abstract: A combination of screw spanner and nut breaker includes a head piece having a nut receiving hole and a female threaded longitudinal hole, a tail piece having a first male threaded protrusion and a second male threaded protrusion, each of which is capable of threadingly engaging with the longitudinal hole, a first engaging piece having a first front end having an angled surface formed to match with an angle surface of a nutlike member, a second engaging piece having a second front end having a knife edge and a female threaded cover capable of threadingly engaging with either one of the protrusions to reserve therein the one protrusion. Such a combination bears the function of a screw spanner when the first engaging piece is put between the head and tail pieces and the other protrusion is screwed on the longitudinal hole and can bear the function of a screw nut breaker when the second engaging piece, instead of the first engaging piece, is put between the head and tail pieces.
