Claw Bar Patents (Class 254/25)
  • Patent number: 8366075
    Abstract: A pry bar sliding fulcrum assembly having a fulcrum and saddle which slidably mates with a conventional prybar and which provides a greater force onto a work material than the conventional prybar alone. The pry bar sliding fulcrum assembly easily and quickly slides away from the work material when a conventional prybar function is desired and slides toward the work material when an enhanced application force or greater prybar end displacement is required. The assembly uniquely mates with or is held with the prybar end whereby the assembly retains a static position relative to the prybar during use.

  • Patent number: 8328164
    Abstract: A hive tool comprises an integrally formed elongated flat bar shaft with concavely shaped sides having a “Z” shaped portion at one end of the longitudinal axis and a gradually tapered straight edge on the other end. The “Z” shape end thereof is proportioned to slide between the frames of a hive box in the bee space and engages a top bar of a frame. The portion of the “Z” shape adjacent to the shaft provides a fulcrum holding one frame in place, while simultaneously lifting the other with an end flanged plane. A thrust and throw of the lever handle is required for operation.

  • Patent number: 8297594
    Abstract: A tool for disconnecting the air and electrical connections between a motor vehicle and a trailer or a utility hookup station includes a handle and a forked member. The trailer connection includes an electrical socket with pins covered by a hinged cover plate; the motor vehicle connection includes a plug member. The forked member of the tool includes a pair of parallel hooks, one at the end of each of two linear elements of the forked member. A sloped interface portion on the forked member of the tool lifts the hinged cover plate away from the trailer's socket. The forked member is placed around the electrical connection adjacent the plug member and is pushed forward to lift the hinged cover plate. Once the hinged cover plate is lifted, the handle is pushed towards the motor vehicle, where the hooks engage lugs on the plug member, thus causing the plug member to separate from the electrical socket. Gripping grooves on the linear elements help to facilitate engagement between the tool and the lugs.

  • Patent number: 7438279
    Abstract: A pulling tool for pulling nails, screws, rivets, pegs, or other protrusions includes a jaw which may be opened to receive the head of the protrusion. The jaw is then at least partially closed against the protrusion, and when the handle of the tool is pulled, the jaw is both urged shut and also away from the surface from which the protrusion extends. Thus, as the protrusion is pulled, its shaft is also more tightly grasped, which helps to pull the protrusion from the surface without stripping off its head/cap. The pulling tool can be provided as a part of a hammer, crowbar, or other conventional tool.

  • Publication number: 20080191181
    Abstract: A pry bar (16) of the type used to move objects through the application of leverage includes a shaft (22) having a roughened surface (24) to increase its coefficient of friction. The roughened surface (24) may extend over an elbowed (28) transition and at least partially over the tip (18). A slip cover (30) is moveably disposed along the shaft (22) into a selective intervening position covering the roughened surface (24) to protect delicate fulcrum points from the roughened surface (24). The slip cover (30) preferably includes a resilient, cantilevered tongue (34) for covering the elbow (28) and a portion of the tip (18). In an alternative embodiment, the slip cover (230, 330) is fitted with a supplemental journaling member (240, 340). In one specific embodiment, the supplemental journaling member (340) includes a roller wheel (346) to provide a rolling interface at the fulcrum point.

  • Patent number: 7338032
    Abstract: A leverage utilizing bar for facilitating prying a flat member from a slender member. A head extends from a handle. The head engages under the flat member and functions as a fulcrum by engaging the slender member and thereby cause the head to pry the flat member from the slender member when the handle is pushed away from the head by the fulcrum pivoting on the slender member. The head includes a pair of hook members and the handle includes a pair of shank members. The pair of hook members of the head together with the pair of shank members of the handle form a pair of main members, respectively, that are generally J-shaped. The pair of main members diverge from each other as they extend from a common proximal end to distal ends of the pair of hook members of the head so as to allow the head to straddle the slender member.
