  • Patent number: 4989326
    Abstract: An apparatus for marking a cloth or other material for the precise placement of stitches in a quilt. The apparatus includes a handle portion having extended therefrom a stem or elongated bar which includes a means for containing a marking medium such as ink or chalk and a wheel rotatably connected to the end of the stem, the wheel having a series of spaced points thereon, the points communicating with the marking medium such that as the wheel is rolled across the cloth the spaced pointed portions of the wheel mark the cloth in a manner that shows the placement of stitches thereon. A spacer bar is provided adjacent the wheel for spacing the wheel a precise distance from the edge of the material. The marking means includes a well and, in an alternative embodiment, may include ink or chalk cartridges placed therein for providing the ink or chalk to the wheel. The handle is angled from the stem such that it provides an easy operation of the pointed wheel across the cloth.

  • Patent number: 4723434
    Abstract: A compression tool head assembly for compressing a metal connector about a conductor. The assembly includes a head section having two, opposing arms moveably connected thereto, each of the arms having a compression point thereon; a rigid column disposed between the opposing arms and having a die mounted therein, the die having a compression point at one end and a mechanism for centering the cylindrical connector over the compression point at approximately a central location between the arms prior to compressing the connector; a hydraulic pump section is connected to the head section and operates to move the head section towards the rigid column; the arms have cammed surfaces which interact with rollers fixed to the rigid column to cause the arms to move towards each other as the head is moved towards the rigid column; as the arms move towards each other the compression points on the arms will compress an article disposed therebetween.

  • Patent number: 4719672
    Abstract: A novel apparatus for clamping a cable in an overhead transmission line system. Said apparatus comprising an elongated clamp having a lower half and an upper half, said lower half having openings to receive U-bolts therethrough to secure the upper half thereto. The lower half having means for allowing the U-bolts to free the upper half from the lower half without disassembling the entire U-bolt assembly. Said means including a slot and an opening, each to receive a leg of the U-bolt, said opening having an interior beveled area to allow the U-bolt to tilt away from the clamp body and said slot permitting a leg of the U-bolt to rotate away from the clamp body. The upper half of the clamp having grooves for retaining the U-bolts, each groove on one side of the clamp having a pair of retainers adjacent thereto crimped over the U-bolt and on the opposite side having a reduced wall area to allow the U-bolt to be lifted off of the grooved area.

  • Patent number: 4667502
    Abstract: A hydraulic apparatus for converting hydraulic pressure into mechanical movement for operating a tool or other device, operated by a pump block having a bore therein and a moveable plunger disposed within said bore. A cylinder is disposed over the pump block. The cylinder is captively held over the pump block and is moveable with respect thereto along the common axis. A fluid reservoir is defined between the cylinder and the pump block, and contains the hydraulic fluid. The plunger is operated by a pair of moveable arms secured to the apparatus and causes pressure to build in the fluid in an inlet chamber which communicates between the pump block and the cylinder. A pressure control valve is mounted adjacent the pump block and limits the hydraulic pressure which may be applied in the system. A release valve and apparatus is provided for releasing the hydraulic pressure and returning it to the reservoir.
