Abstract
The invention pertains to a winch construction for use with portable power pulls, the winch consisting of two cast portions interconnected by bolts wherein hub portions include opposed and engaging faces in which cable anchor and cable-receiving recesses are defined wherein, upon assembly, the winch accomodates the cable inner end and anchor within its hub configuration and the cable end is supported in such a manner to meet acceptable cable stress standards.
Claims11
In a power pull comprising a frame having an anchor defined thereon, a ratchet winch rotatably mounted on said frame having a retaining dog, a cable wound on said winch, and an operating lever pivotally mounted on said frame operatively associated with said ratchet winch, the improvement comprising said winch constituting first and second molded portions, said portions each including a hub portion and a flange portion each having a periphery, ratchet teeth defined on the periphery of one of said flange portions, said portions each including an axial shaft receiving bore concentrically extending through said hub portions and a radially extending hub portion face adapted to engage the face of the other hub portion, a cable anchor recess defined in said hub face of each hub portion, a cable receiving recess defined in said hub face of each hub portion of lesser axial dimension than said cable anchor recesses, said cable receiving recesses intersecting the associated cable anchor recess and the associated hub portion periphery, and releasable fastening means maintaining said first and second winch portions in assembled relation with said hub portion faces in engagement wherein said cable anchor recesses together defined a cable anchor chamber and said cable receiving recesses together define a cable chamber adjacent said cable anchor chamber.
A winch for a power pull comprising, in combination, first and second molded portions, said portions each including a hub portion and a flange portion each having a periphery, ratchet teeth defined on the periphery of one of said flange portions, said portions each including an axial shaft receiving bore concentrically extending through said hub portions and a radially extending hub portion face adapted to engage the face of the other hub portion, a cable anchor recess defined in said hub face of each hub portion, a cable receiving recess defined in said hub face of each hub portion of lesser axial dimension than said cable anchor recesses, said cable receiving recesses intersecting the associated cable anchor recess and the associated hub portion periphery, mutually interfitting keying means defined upon said hub portions' faces, and releasable fastening means maintaining said first and second winch portions in assembled relation with said hub portions faces in engagement wherein said keying means interfit, said cable anchor recesses together define a cable anchor chamber and said cable receiving recesses together define a cable chamber adjacent said cable anchor chamber.
