  • Patent number: 7347134
    Abstract: A dispenser for dispensing and advancing sheet material is provided. The dispenser includes a frame and a drive roller rotationally mounted to the frame. The drive roller is configured for engagement with sheet material so that rotation of the drive roller causes movement of the sheet material. A segmented gear with first and second drive segments is mounted to the frame and is in communication with the drive roller. A spring is included and is in communication with the segmented gear. The spring is configured so that rotation of the segmented gear causes the spring to store potential energy. Release of potential energy in the spring causes the segmented gear to rotate. A cutting blade is provided and is configured for cutting the sheet material in order to release potential energy. The dispenser allows for a piece of sheet material to be dispensed therefrom and subsequently presents the user with a new piece of sheet material for future removal.

  • Patent number: 7340978
    Abstract: A method for manufacturing a rotary tool for chip removing machining with at least one chip flute that extends in the longitudinal direction of the tool. The method involves preparing a mixture of a cemented carbide, cermet or ceramics powder and a carrier, such as a polymer, and placing the mixture in an extruding machine. The mixture is extruded in a feed direction by means of a die to form the diameter of the mixture body. The mixture body passes against a chisel which forms a chip flute in the outer periphery of the mixture body by chip-removing machining. When the chisel is displaced away from the mixture body, a non-fluted shaft portion is formed. By rotating the mixture body while contacted by the chisel, a helical chip flute can be formed. Alternatively, the body could be twisted after a straight flute has been formed, whereupon the flute becomes helical.

  • Patent number: 7308763
    Abstract: A sealant cutting tool including a handle defining a blade slot. Also included is a clamping bolt having a clamp axis transverse the blade slot, which clamping bolt is threadably engaged with the handle. In addition, a “T” pull is operatively associated with the clamping bolt so that rotation of the “T” pull around the clamp axis causes a distal end of the clamping bolt to move relative to the blade slot. The sealant cutting tool may include a blade received in the blade slot in operative association with the clamping bolt. In addition, the “T” pull may include an engagement head operatively associated with a proximal end of the clamping bolt. The clamping bolt may include a noncylindrical shoulder received through a mating, noncircular opening formed in the engagement head. Thus, the noncircular opening may be selectively engaged with the noncylindrical shoulder, allowing the “T” pull to be selectively engaged or disengaged from the clamping bolt.

  • Patent number: 7296356
    Abstract: The present invention discloses an adjustable base for a portable saw and a portable saw therefore. The base includes a longitudinal shell secured to the housing, and mounted to a baseplate. A shaft is mounted to the housing extending through a slot formed in the shell. A collar is connected to the shaft and has a first cam surface cooperating with a corresponding second cam surface of the housing. Rotation of the collar in an unlocked direction extends the shaft away from the housing. A clamp member is received within a shell inner region and cooperates with the shaft. The shaft is threadably engaged to one of the collar, the housing or the clamp member so that rotation of the collar in the unlocked direction either extends the shaft further away from the housing or extends the clamp member along the shaft away from the housing.
