ABSTRACT:
A stretcher apparatus for tightening multiple wire fences. The apparatus preferably comprises a pair of spaced apart, vertically parallel pulling angle members, a pair of horizontally disposed, rotatable adjusting rods extending between the pulling members and threadably coupled thereto, and a plurality of eye bolts secured in vertically spaced apart relation to each pulling angle member and adapted to be attached to the individual wire elements of a fence to be tightened. The pulling rods each comprise a central turnbuckle to which first and second threaded segments are weldably secured. Each turnbuckle is fastened to lefthand and righthand threaded segments threadably received by opposite pulling angle members. Rotation of the turnbuckles draws the fence elements together. Elongated reinforcement members are rigidly secured to the pulling angle members between the first and second adjusting rods to prevent deformation of the pulling angle members when the apparatus is operated.
