  • Patent number: 9603310
    Abstract: Loppers include first and second elongated handles that are both directly connected and indirectly connected through a linkage assembly. The first handle has a static blade having a concave shearing edge extending generally transverse from the longitudinal axis of the first handle. The second handle has a curved end portion that curves toward the first handle and is pivotally secured to the static blade. An articulated blade has a convex cutting edge and is rotatably secured to the static blade. A link connects the curved end portion to an end of the articulated blade. Movement of the second handle relative to the first handle pivots the curved end portion about the static blade, thereby moving the cutting edge relative to the shearing edge via the link. The static blade and articulate blade are offset from the handles and extend generally transverse to the longitudinal axis of the first handle.

    Abstract: A multi-function pipe cutting and fitting tool includes a spring biased connecting rod, a pair of plier teeth and a pair of friction teeth. The spring biased connecting rod improves the pipe cutting function of the tool by improving the operation of a movable jaw toward engagement of a fixed jaw. The pair of plier teeth positioned on one side of the tool allows a user to firmly grip a pipe or other object to be held in place. The pair of friction teeth positioned on an opposite side of the tool allows a user to more reliably engage an object such as a cap on a can of glue. The inclusion of all of these features in the same tool allows a user to perform multiple functions easily and more rapidly.

  • Patent number: 7743509
    Abstract: A hand-held and hand-operated cutting tool particularly well suited for cleanly and quickly cutting plastic pipe or tubing, rubber hose, or the like is provided. The tool has a blade which is easily manually removed from and replaced into the cutting tool without the use of additional tools. The blade is slid into the tool and then rotated slightly into an initial operating or loaded position whereat a blade pivot pin may be inserted into the tool and through a hole provided in the blade. During use, the blade is rotatable in increments or steps from a retracted position in which it is substantially enclosed within the tool housing to a cut off position in which it cooperates with a stationary cradle anvil so as to sever the article to be cut. A ratchet drive interconnects a movable handle and the blade so as to incrementally drive the blade towards its cut off position upon manipulation of the handle.

  • Patent number: 7690119
    Abstract: An apparatus for cutting a bolt includes a first member and a second member that are adapted to pivot about an axis. An L-shaped member is pivotally attached to an end of the second member. A sliding member is attached to the L-shaped member that bears on an exterior of the first member when the L-shaped member is fully pivoted toward the first member. A threaded rod includes a first end that is attached to the sliding member. The threaded rod engages with a threaded opening provided in the L-shaped member. A knob that is attached to the threaded rod is tightened which urges the sliding member and the first member toward the second member and severs the bolt that is disposed in a pair of openings proximate the axis.

    Abstract: A cutting tool includes a first lever having a first end and a second end, the first end being connected to a second elongated element in an articulated manner at a third pivot point and the second end being arranged to engage with a tongue in a metal plate to transmit force from the second elongated element to a first blade in the metal plate so as to perform a cutting movement with a cutting jaw when the first and the second elongated elements are shifted towards one another. The cutting tool also comprises an engagement device provided in the tongue and arranged to receive the second end of the lever optionally at two or more engagement points with respect to the first pivot point so as to perform stepwise cutting movements. The engagement points are placed in the tongue successively away from the third pivot point.

  • Publication number: 20090293288
    Abstract: Disclosed is an improved pipe cutting tool based upon a ratchet closure action wherein handles are pivotedly attached to allow successive movement of a cutting blade in response to the squeezing of the handles. The handles are also hingedly coupled to the cutting member to maintain the cutting member in a position perpendicular to the tubular item to be cut while allowing the operator to squeeze the handles at offset angles, up to and including a right angle cut. The hinged handles allow for offset operation without forgoing the ease of operation by the consumer or causing a large reduction in the mechanical advantage. A ratchet allows sequential advancement of a cutting member toward a tubular shaped jaw that holds the item to be cut.
