  • String loop tensioning pliers device and method of use
    Patent number: 8783659
    Abstract: A string loop tensioning pliers device includes a first member comprising a first handle and a fixed arcuate jaw comprising an upper jaw and a lower jaw. The lower jaw has an arcuate claw end and the upper jaw has a first lateral dowel pin end and three in-line lateral facing beveled prongs. A second member comprises a second handle pivotally connected above the first member and includes a notched end opposite the handle and a second lateral dowel pin configured to join with the middle prong when the pliers are closed. A method for using the disclosed tensioning pliers includes tensioning a string knotted to the bowstring, spreading a loop created on the bowstring and tensioning the created loop by inserting the middle prong joined with the second lateral dowel through the formed loop and squeezing the pliers to separate the middle prong and the second lateral dowel.

  • System for inhauling and outhauling lines
    Patent number: 4353527
    Abstract: A cable hauling system includes a drive shaft, a haulback shaft with a haulback drum mounted thereon, and a main shaft with a main drum mounted thereon. A first pair of gears operatively associated with the drive shaft and the main shaft includes a positively acting clutch for selectively coupling the drive shaft to the main shaft in driving relationship through the first pair of gears. Second and third pairs of gears are operatively associated with the drive shaft and the haulback shaft. An energy-dissipating, power transfer device is associated with both the second and third pairs of gears to selectively couple one or the other of the second and third pairs of gears in driving relationship with the haulback shaft.
