An adjustable double-ended box wrench comprising:
- (A) a wrench body of an elongated shape including:
- (a) a hollow intermediate portion of an elongated shape having opposite ends, said intermediate portion including a base wall having an adjusting opening and also including a pair of spaced side walls connected by the base wall and projecting therefrom, and said intermediate portion having a pair of adjusting seats located between the side walls on opposite extremities of the adjusting opening toward the opposite ends of the intermediate portion;
- (b) a large box wrench connected to one end of the intermediate portion of the wrench body and including support portions extending therefrom in a diverging relationship to each other, said large box wrench also including engagement portions extending from its support portions in a converging relationship to each other and having engagement surfaces that define an included angle of about 60.degree., and said large box wrench also including a connecting portion;
- and
- (c) a small box wrench connected to the other end of the intermediate portion of the wrench body and including support portions extending therefrom in a diverging relationship to each other, said small box wrench also including engagement portions extending from its support portions in a converging relationship to each other and having engagement surfaces that define an included angle of about 60.degree., and said small box wrench also including a connecting portion that connects its engagement portions;
- (B) an adjustable jaw assembly supported by the wrench body and including:
- (a) an elongated adjusting member supported within the hollow intermediate portion of the wrench body for movement along the length thereof in opposite directions toward and away from the large and small box wrenches, said adjusting member having an intermediate portion including an externally threaded portion adjacent the adjusting opening in the base wall of the intermediate portion of the wrench body, and said adjusting member having end portions that extend in opposite directions from the threaded intermediate portion toward the large and small box wrenches;
- (b) an adjusting nut that threadingly receives the externally threaded portion of the intermediate portion of the adjusting member, said adjusting nut being located within the adjusting opening of the base wall of the wrench body, and the adjusting nut having oppositely facing surfaces that engage the adjusting seats of the intermediate portion of the wrench body to move the adjusting member in opposite directions with respect to the large and small box wrenches upon rotation of the adjusting nut in opposite directions;
- and
- (c) a pair of jaw ends on the opposite ends of the end portions of the adjusting member, said pair of jaw ends being respectively received between the support and engagement portions of the large and small box wrenches, and each jaw end including a generally flat jaw surface that defines an angle of about 60.degree. with respect to each of the pair of engagement surfaces of the associated box wrench to permit gripping of a hexagonal nut or bolt head thereby upon appropriate rotational adjustment of the adjusting nut;
- and
- (C) a cover plate that extends between the side walls of the wrench body and is secured thereto to retain the adjustable jaw assembly within the hollow intermediate portion of the wrench body, said cover plate having an adjusting opening through which the adjusting nut projects to permit the rotational adjustment from either side of the wrench, the externally threaded intermediate portion of the adjusting member having a greater size than the spacing between the cover plate and the base wall of the wrench body so as to be received within the openings thereof, and the openings of the cover plate and base wall of the wrench body having end surfaces that engage the threaded intermediate portion of the adjusting member in order to limit movement of the adjusting member in opposite directions.
