  • Patent number: 4876757
    Abstract: A tool that allows a user to salvage a tube of caulk after the nozzle has become clogged. The approach is to cut off the nozzle to leave a stub of sufficient length, tap threads into the stub, and screw in a replacement nozzle. The tool comprises a body having a generally semi-cylindrical recess conforming to the base region of the caulking tube nozzle. A blade is mounted in the recess for cutting of the nozzle at a predetermined distance from the base of the nozzle. A tap, suitable for cutting threads into the stub of the nozzle, is rigidly mounted to and protrudes from the body. The tool includes provision for rendering the blade ineffective to cut nozzles or fingers when the tool is being used other than in the cutting mode.

  • Patent number: 4564148
    Abstract: A toilet paper dispenser (5) includes a roll-storing chamber (20) adapted for incorporation behind a room wall and a pair of facing guides for feeding rolls (10, 12), one at a time, to an exposed position at least partially in front of the wall. To this end, the chamber (20) has a front wall (35) formed with an opening (42) in a lower portion thereof commensurate with an aperture (30) in the room wall. Each of the facing guides includes a vertical channel (60) within the chamber (20) and a horizontal channel (62) contiguous therewith and extending to a point outside the chamber. The channels are sized and spaced to accommodate spindle ends (27) projecting beyond the end faces of a toilet paper roll to be dispensed. The end portions (67) of the horizontal channels are formed to support a roll in the exposed use position. One or both of the horizontal channels (62) may be formed with an open segment (75) that allows insertion and removal of the spindle.
