  • Patent number: 5951221
    Abstract: Apparatus for cutting a hole through a plastic liner in a gas or other main comprises a body forming module of a train of modules adapted to travel through the main. The body has a radially movable platform carrying a cutter. The platform has four cams engaging four cams pivotally mounted on tie-bars. Advancing movement of the platform pushes the cams outwardly causing support legs to move outwardly and to cause four slave legs carried by the support legs to engage the plastic liner. Further advancing movement of the platform causes the cutter to engage the liner and also holds the support legs in their advanced position as noses on the cams traverse the faces of the cams.

  • Patent number: 5951216
    Abstract: A programmable, variable volume and pressure, coolant system regulating the amount of coolant flow to a cutting tool by controlling the speed of a coolant pump, and is comprised of a fluid control unit and an electrical control panel. The fluid control unit includes a pump and a AC pump motor operatively connected thereto. The electrical control panel includes: a power supply; circuit breakers; a computer; a variable frequency drive; control relays; and a junction block for making electrical connections to the control panel. The computer receives signals from the tool and a pressure transducer, and is programmed with information concerning the total flow area of the coolant orifices. Using this information, the computer determines an ideal pump speed, and sends a control signal to the variable frequency drive which in turn determines the pump motor speed.

  • Patent number: 5927913
    Abstract: A tool holder having a holder body, a collet, an intermediate rod, a clamp bolt and a pull stud. The collet and the intermediate rod are integrally connected by screwing. The collet is retracted into the holder body via the intermediate rod by rotating the clamp bolt in the first direction, and presses and holds a cutting tool. In this event, a head of the clamp bolt comes in pressure-contact with a stepped surface of the holder body by surface friction and rotates. On the other hand, in order to release the cutting tool, the clamp bolt is rotated in the second direction opposite to the first direction. In this event, the clamp bolt is rotated by rolling friction via steel balls inserted between the head and a center hole of the holder body, and the collet is pressed out forward.

  • Patent number: 5918907
    Abstract: A reading apparatus capable to support a book with adjustable angle includes: a base having a guiding groove and two sleeves, a supporting mechanism for supporting the book, and a clamping member for clamping the book on the supporting mechanism. The supporting mechanism includes a M-shaped frame defining two side rods, an elongated middle rod and an adjusting plate. The two side bars of the M-shaped frame are pivotally connected to the sleeves respectively. The middle rod is connected at middle of the M-shaped frame at one end thereof and is parallel to the two side bars. The adjusting plate is slidably and rotatably engaged with the middle rod and is formed with an oblique edge which can be received by the guiding groove at an adjustable position. The clamping member is pivoted to the front edge of the base for providing a clamping force facing the M-shaped frame. By adjusting the position of the adjusting plate along the guiding groove, the angle between the M-shaped frame and the base can be changed.

  • Patent number: 5918886
    Abstract: A keyless drill chuck includes a raising-and-lowering member which moves back and forth with reference to a shaft in order to secure a rear portion of the cutting tool, and jaws which grip the cutting tool in association with the movement of the raising-and-lowering member toward the jaws while the internal diameter of a circle defined by the jaws. The rear portion of the cutting tool is automatically gripped without the use of a chuck handle by means of a machining resistance transmitted to the jaws from the cutting tool and of the movement of the raising-and-lowering member caused by torsional torque transmitted to a shaft. A V-shaped recess is formed in the end of the raising-and-lowering member facing the jaws, so that the rear portion of the cutting tool can be removable, yet attached to the V-shaped recess.
