  • Patent number: 9809484
    Abstract: A bottle cutter has a body having two generally arcuate components connected to each other by straight parallel members permitting one component to slide relative to the other component between an open, non-cutting position and a closed, cutting position. Each arcuate component includes a plurality of an inwardly facing rollers that facilitate rotation of a bottle held by the bottle cutter in the closed, cutting position. A cutting wheel disposed on one of the two components cuts, or at least scores, the bottle as the bottle is rotated. If the bottle is only scored, separation of the top and bottom portions of the bottle may be effected using hot and cold water to induce differential thermal stresses in the glass. The edge may be finished or polished using sandpaper or any other suitable abrasive material.

    Abstract: A pipe peeler for removing a uniform layer of material from the outer surface of a polyethylene pipe is provided. The device comprises a body, a blade, a chain coupled near a first face of the body, a means for coupling the other end of the chain to the body near a second face of the body, a means for tightening the chain around a pipe, and a grip for rotating the device around the pipe in order to peel the pipe. The chain may define a helix shape when wrapped around the pipe, creating a spiral track on the pipe that the blade will follow when the device is pushed around the pipe, thereby creating a uniform spiral peel.

  • Patent number: 5461955
    Abstract: A device for cutting pipe comprising two sleeves, which sleeves are securely tensionable about a pipe and adjacent to each other. An axial cleft remains exposed between the two sleeves, in which lies the cutting line. A chain type pipe cutter runs upon the sleeves, the cutting disks of the pipe cutter engaging the pipe between the sleeves and severing the pipe. The rollers of the cutting disks are supported by the sleeves, whereby the cutting depth is limited. Further, support bearing rollers support the chain type pipe cutter upon the sleeves. The device is economical and makes possible the cutting of pipes even of minimal form stability without deforming the pipes.

  • Patent number: 5086961
    Abstract: A pipe severing device (1) and method utilizing a chain (13) having stress inducing wheels (19) efficiently and safely severs brittle materials including cast iron, vitreous clay, cement and asbestos pipe. The device includes an actuating handle (6) which pivots over a pipe support surface (3). Upon pivoting over the surface, holddown arms (7) attached to the actuating handle frictionally grasp a pipe. The handle may then pivot about a second point or remain rigid, in either case engaging a first limit switch (25) which actuates a hydraulic cylinder (35). The hydraulic cylinder tightens the chain causing the stress inducing wheels to create stress concentration points around the circumference of the pipe. Cracks propagate between stress concentration points, quickly severing the pipe. The pipe support surface includes resilient pads (5a,b) which further frictionally grasp the pipe.

  • Patent number: 4763413
    Abstract: A chain tube cutter has two plier-like levers with hand grips on one side of a pivot pin which projects from one lever through a slot in the other and chain-engaging arms on the other side of the pivot pin. A link cutting chain is secured to one arm. The other arm has notches for engaging a selected link of the chain after it is wrapped around the tube to be cut. Squeezing the hand grips together generally keeps the chain adjusted about the tube as it is cut by rotating the cutter relative to the tube, but to provide greater initial and operational adjustment, the pivot pin is variably positionable in the slot.
