Abstract: A fastener driving tool which uses the mechanical advantage of a lever to aid in the loosening and tightening of screws, bolts, nuts, and the like. The tool amplifies the force of a user that is exerted on a fastener bit (e.g. screwdriver blade) and a fastener head (e.g. screw head) thereby reducing the chance of the fastener bit slipping off the fastener head. A lever arm has a first end which attaches to an adjacent nearby screw or bolt. The fastener bit is attached to the lever arm and engages the targeted fastener head. The fastener bit functions as the fulcrum (i.e. the support about which the lever turns) of the lever arm. The user exerts downward force on the second end of the lever arm while using a conventional torquing tool (e.g. screwdriver, wrench, etc.) to loosen or tighten the hard to turn fastener.

Abstract: A support arm for supporting a power screwdriver or similar device. The support arm prevents the transmission of the rotational force generated by the screwdriver to the hands and wrists of the operator. The support arm includes an internal lock plate secured to an extensible rod, which is disposed within a generally square outer housing. The internal lock includes a pair of generally square lock plates mounted on either side of a Teflon.RTM. guide sleeve, which acts as a slide bearing. The sides of the lock plates are flat and are used to abut against the interior flat surfaces to prevent the extensible rod from rotating inside the housing. A pair of universal joints are connected to the housing and rod to permit limited pivotal movement. The support arm may be mounted to a shiftable carriage, which rides on a transverse railing.

Abstract: A power transmission tool for the installation and removal of a spanner nut (15) on a threaded end of a drive shaft (27) comprises a torque reactor plate (32) with a central threaded aperture (35,37) for threaded engagement with a wrench shaft (39). The pitch of the wrench and reactor plate threads (37,39) is the same as the pitch of the drive shaft and spanner nut threads. The reactor plate (32) is fastened (60,63,65) to a drive flange (20), the flange being mounted on an end of the drive shaft and having splines to prevent relative movement therebetween. An aperture (73) is formed in the torque reactor plate for receiving a bar which is used to react the torque applied to the drive shaft/flange combination by the wrench via the nut, thereby preventing rotation of the flange and shaft combination when torque is applied to the wrench.

Abstract: There is presented a device for operating a valve handle in an underground location spaced from a ground surface, the device having brace means for preventing rotation of a housing portion thereof during operation of a turning portion thereof. The brace means includes two body portions, each substantially flat on an upper surface thereof and adapted to receive a foot of an operator so as to bring the weight of the operator to bear on the brace means which engage the ground surface.

Abstract: A locking plier structure arranged to secure a shaft includes facing movable semi-cylindrical inserts mounted relative to respective fixed movable jaws of the plier structure such that the movable jaw includes fixedly mounted thereto a support shaft secured in turn to a support plate.

Abstract: A wrench assembly for retaining a pair of propane tanks in spaced relationship, while providing a convenient storage structure for a wrench required for maintenance of the propane tanks. The assembly includes a threaded rod positioned between the propane tanks, and a bracket securely retains the tanks in position when a wrench having a threaded opening is screwed onto the threaded rod. The assembly overcomes the problems associated with the misuse of tools when the appropriate wrench is unavailable.

Abstract: A wrench tool for preventing cross threading during engagement of nuts with studs is provided. A driving body receives the nut and alignment with the stud is effected through a locating assembly pivotally connected to the driving body. The locating assembly is moved out of engagement with the stud by the movement of the driving body in the tightening direction.

Abstract: A support (10) for a hand operated rotatable tool, such as a wheel brace (12), having a socket (74) for location upon a nut/stud (14) for supporting an elbow (72) of the tool during use to inhibit slippage of the socket (74) off the nut/stud (14). The support (10) solves the problem of loosening nuts/studs (14) tightened with pneumatic wrenches--which loosening is often difficult and sometimes impossible with the relatively small wheel braces (12) provided in vehicle tool kits. The support (10) has a cradle (26) whose height above the ground can be adjusted so as to support the wheel brace (12) whilst maintaining an axis of the socket (74) in alignment with an axis of the nut/stud (14). The cradle (26) is mounted upon a frame (19) having a base (20), a first leg (22) and a second leg (24). The first leg (22) is pivoted between the base (20) and the second leg (24) so that the support (10) can be collapsed to a storage condition and erected to an in-use condition with the cradle (26) disposed upper-most.

Abstract: A lug wrench support for temporary placement on a wheel hub and including a sleeve having appendages on the sleeve outer wall defining wrench receiving grooves. A first internal wall surface of the sleeve is of diameter to receive and frictionally engage a wheel hub while a second internal wall surface of the sleeve is of a lesser diameter and frictionally engages a wheel hub of lesser size than the first mentioned wheel hub. The wrench receiving grooves support that portion of a lug wrench adjacent the socket end of the wrench during rotation of wheel lug nuts. An eye of each appendage serves to retain the lug wrench in the appendage groove.

Abstract: A lug nut removal tool has an upright support leg on a base, a clamp which can be adjusted up and down on the leg, a pivot bracket on the clamp, and a lug wrench mounted for axial sliding and rotation on the pivot bracket. The stand formed by the support leg and base holds the lug wrench at the proper elevation to be applied to lug nuts on a wheel, and and elongated handle on the wrench allows the wrench to be easily turned while applied to the lug nuts. The leg, wrench bar and handle can be pivoted to positions parallel to one another to provide for compact storage of the tool when it is idle.

Abstract: An apparatus for removing a feedthrough connector mounted in an internally-threaded access opening in a wall of a pressurized vessel includes an elongated hollow sleeve defining a chamber and having upper and lower opposite open ends. A flange mounting an O-ring is fixed on the lower open end of the sleeve for sealably attaching the sleeve to the vessel wall about the access opening thereof and the connector mounted therein. A cap is sealably mounted to the upper open end of the sleeve for closing the same, but is removable for opening the upper sleeve open end. A tool shaft extends through the cap and is vertically reciprocally movable relative to the cap and through the sleeve chamber between upper and lower sleeve ends. The shaft is operable for engaging the connector, unthreading the same from the wall access opening and lifting the connector to the upper sleeve end. Removal of the cap will remove the shaft and connector engaged therewith from the sleeve.
