The tool comprises two leg members, each pivotally connected at their upper ends to the opposite ends of a crossmember. Attached at approximately the mid-point of each leg member is a horizontally aligned chain designed to limit the distance the leg members can be spread apart during operation. A second chain is attached at one end to approximately the mid-point of the cross-member. During operation, the second chain hangs vertically from the crossmember. A hook is attached to the opposite end of the hook which either directly engages the edge of the cover or a lifting element attached to the cover. The chain is adjustable in length so that the leg members may be spread apart on opposite sides of the cover. During use, the second chain is attached to the cover and the tool is moved to one side which lifts and moves the cover to the desired position. The same movement is used to install the cover.

  • Patent number: 4637769
    Abstract: A carrier for lifting and transporting a log. The carrier includes a wheeled frame, a hook, and a load stabilizer. The hook has, at one end, a hinged attachment to the frame, and, at the other end, both a point for gripping one side of the log and a point for prodding logs into position. The load stabilizer is movably attached to the frame. After a log is initially gripped between the hook and the frame, the stabilizer is moved into a position in which the stabilizer applies a force to the log to hold the log against the hook and thereby prevent the hook from losing its grip on the log.

  • Patent number: 4221416
    Abstract: An apparatus for lifting logs from the ground to an elevated position in order to allow for cutting of the logs. The log lifter comprises a lever arm having one end thereof bent downwardly to form a leg, the leg having on the end thereof a detachable support tube which serves as a fulcrum about which the lever arm may pivot. The log lifting apparatus includes a first claw which is attached at the bend between the lever arm and the leg. The log lifting apparatus further includes a log gripping arm which is pivotably mounted with respect to the lever arm and which terminates in a second claw. To lift a log that is lying on the ground, the lever arm is held in the upright position and the log gripping arm is pivoted in the withdrawn position so as to be adjacent to the lever arm. The first claw is slipped under the log and the log gripping arm is then pivoted to provide for engagement of the log with the second claw. The lever arm is then pivoted, preferably by manual means, about the support tube.

  • Patent number: 4013313
    Abstract: Disclosed are turning tools for elongated agricultural irrigation pipes which lie along the earth's surface and which include longitudinally aligned gated ports along each pipe segment for radial water emergence therefrom. The pipe turning tool, which ensures that the gated watering ports can be positioned the appropriate distance above the ground, generally comprises: an arcuate shoulder for abutment against the pipe outer side, an elongate handle rigidly attached to the shoulder and extending rearwardly therefrom and away from the pipe, and a fixed positioned stationary detent extending downwardly from a rigidly secured header and which detent is engageable with a radial discontinuity on the pipe thereby effecting turning about the pipe central-axis. Alternate tool embodiments are disclosed appropriate for use with latch-recess type radial pipe protuberances and depending upon the latch-recess spatial relationship to the aligned gated ports.
