Abstract
A post puller having substantially universal application for pulling posts of various cross-sectional configurations and characterized by a pair of transversely spaced jaws carried by the pulling clevis opposite the clevis pin, the clevis being pivotally connected adjacent one end of a lever handle which is pivotally supported by a stand, the space between the jaws accommodating the leg of T-shaped posts, and the jaws engaging the base of the U-shaped posts, during the pulling operation.
Claims8
A post-pulling apparatus comprising:
- (a) a fulcrum stand having a ground-engaging foot at one of its ends;
- (b) a lever handle pivotally mounted at a point intermediate its ends on said fulcrum stand;
- (c) a generally U-shaped clevis pivotally attached to said lever handle adjacent one of its ends and outwardly of the point of attachment of said lever handle to said fulcrum stand and being constructed and arranged to clampingly engage a post to be pulled;
- (d) said clevis having a pair of spaced opposite legs extending outwardly relative to its point of attachment to said lever handle and having free ends;
- (e) a clevis pin extending between said free ends of said clevis;
- (f) a pair of transversely spaced jaws carried by said clevis opposite said clevis pin and spaced therefrom at locations between said clevis pin and the point of pivotal attachment of said clevis to said lever handle;
- (g) said jaws being constructed and arranged to define a space therebetween sufficient to receive the leg of a T-shaped post therebetween;
- (h) said jaws, said legs and said clevis pin being constructed and arranged to define a space therebetween which will receive either U-shaped, T-shaped, or angle posts therewithin in clamping engagement.
