  • Patent number: 9114546
    Abstract: A cutting guide assembly facilitates straight and circular cuts using a power cutting tool. The assembly includes a saddle and a tape measure coupled to the saddle. The tape measure has a tape extendable from the saddle. A tab is coupled to and extends from a distal end of the tape. A guide member is coupled to the saddle and has a guide flange alignable with a proximal end of the tape relative to the saddle. Thus, a distance between the distal end of the tape and the guide flange of the guide member is measured by the measuring tape. A tool attachment is coupled to a cutting tool. A slot is positioned in the tool attachment and aligned with a cutting blade of the cutting tool. The slot receives the tab.

  • Patent number: 8950307
    Abstract: A jig for use in cutting an elongate workpiece with a saw blade features separate first and second guide members, each having a respective slot that passes through the guide member on a path spanning along a lengthwise dimension of the guide member. The paths of the respective slots match one another in shape, and a mounting mechanism is operable to secure each guide member in a tightened position abutted against a respective one of two opposing sides of the workpiece. The elongate workpiece is cuttable cross-wise by insertion of the saw blade through the respective slots on the opposing sides of the workpiece and cutting into the workpiece along the path of the slots. The separate guide members can accommodate workpieces of varying size and shape between them while guiding the blade on two sides of the workpiece for optimal reliability and cut accuracy.

The tool comprises a tool body and a canister interface with a joint that permits the tool body to rotate about the canister interface. The tool can also comprise a marking implement that is secured to the tool body, and which implement is configured to mark the surface of the canister such as to mark the surface when the canister is depleted of its contents. In one example, the marking implement comprises a marking point shaped and constructed so as to puncture the surface of the canister in a manner that exposes the interior of the canister to the environment.

  • Patent number: 7823489
    Abstract: A system and/or method for making a pizza pie having an outer cheese portion comprises a cutting tool and/or a cutting guide to enable formation of at least one opening at an outer crust region of a pizza pie to cause an inner cheese portion embedded within the outer crust to flow through the at least one opening, thereby forming the outer cheese portion at the upper surface of the outer crust. A cutting tool of the system comprises a rotatable disc with notches in its cutting surface to enable formation of the at least one opening in the outer crust. A cutting guide of the system comprises a generally disc shaped member with a support surface at its outer edge for supporting and guiding application of a cutting device against an outer crust region of a pizza dough.

  • Patent number: 7806750
    Abstract: An apparatus and method for cutting a material using a water jet. A central shaft is mounted so as to extend outward from a material to be cut. A support member is mounted on the central shaft so as to extend transversely therefrom. At least one water jet cutting head is mounted on the support member so as to be translatable therealong. In addition, the at least one water jet cutting head is mounted so as to be rotatable about the central shaft. By controlling the translatory and rotational motion of the at least one water jet cutting head (for example, using computer numerical control or other computer control), a desired cut pattern can be followed with respect to the material being cut.

  • Patent number: 7784387
    Abstract: A kit for constructing a sawhead comprises a pair of plates adapted to be stacked upon and secured to one another by bolts to form a plate stack. The kit further comprises a pair of elongate guide receivers. Each guide receiver has a longitudinal axis and an interior wall which defines a bore extending through the each guide receiver and through which bore the longitudinal axis extends. The interior wall has a cross-section which is substantially constant along the length of each guide receiver. The guide receivers are adapted to be mounted to the plate stack by bolts at respective operative positions whereat the longitudinal axes are oriented parallel to one another and whereat the guide receivers are spaced from one another in a direction transverse to the axes.

  • Patent number: 7757592
    Abstract: Operating a power saw between a pair of parallel guide rails, which engage opposing sides of saw base plate to constrain the motion of the saw to a straight path, allows for precise cuts. A set of two or more fences allows for multiple cutting options. In some embodiments, non-parallel fences coupled to the guide rails allow for precise cuts at more than just a single angle. In some embodiments, two fences may engage opposing sides of the object to be cut simultaneously, holding the object more securely with respect to the guide rails than would a single fence. A possible clamping force holding the two fences against the object allows the miter guide to remain fixed relative to the object so that the user's hand may be freed for another task, such as holding the saw with both hands.

  • Patent number: 7703856
    Abstract: A manhole cover frame removal apparatus has a ring-shaped base with a circular track thereon and a saw mounting framework disposed atop the base. Rollers allow the saw mounting framework to advance in rotation about aligned vertical axes of the frame and the base. A saw mounting arm is joined to the framework and may be raised and lowered and locked in the raised position. A saw carriage is mounted on the saw arm for reciprocal movement toward and away from a saw arm hinge axis. A single saw motor is mounted on the carriage and can be immobilized at selected angles. Separate horizontal-cut and vertical-cut saw blades are alternatively and interchangeably attached to the saw blade rotor.

  • Publication number: 20100043609
    Abstract: A cutting apparatus for columnar items such as metal pipes has a base frame that supports a movable cutting blade. At least one blade actuator is disposed between the blade and the frame to drive the blade back and forth between retracted and extended positions. First and second arms are pivotably connected to the frame and moveable between disengaged and engaged positions. An arm actuator is associated with each arm and drives each arm between the disengaged and engaged positions. A segmented collar engages the entire circumference of the columnar item being cut. The blade is supported by the frame and the arms during the cutting process while the collar supports the material of the columnar item adjacent the cut.
