| Abstract: |
A multi-purpose tool, most useful for barbeque work, comprises a pair of parallel arms with barbeque implements at distal ends thereof and which are hingedly joined by a pair of spaced cross members so as to form a movable parallelogram at the other end thereof. This allows the tool to be adjusted in either of two positions so that the arms are adjacent and parallel with the distal end of either arm projecting forward so that its implement can be used alone, or with the arms parallel and spaced apart so that the arms can be squeezed together so that the implements can used as a pair of tongs. One implement is a fork and the other is a spatula. A pair of handles are provided in the middle of the arms. A grasping and hanging ring is attached to the middle of the end cross member. One end of the end cross member is pivotably attached to its arm by a bolt and thumbscrew so that it can be loosened and the parts can be thereafter locked in position; the pivot includes a detent lock for holding the cross member and arm orthogonally. The pivots are preferably formed at locations offset from the arms.

I claim:
1. A multi-purpose tool, comprising:
- first and second elongated arms, each arm having a proximal end and a distal end at the end opposite said proximal end, each arm comprising first and second portions, said first portion being at said proximal end and said second portion comprising the rest of each arm, including said distal end thereof, said first portion being shorter than said second portion;
- said distal end of each arm having a working implement thereat;
- joinder means for joining said proximal ends of said arms together, said joinder means comprising first and second crossarms, each crossarm comprising a member having first and second ends;
- said first ends of said crossarms being hingedly attached to said first arm at spaced locations thereon, said locations defining said first portion of said first arm, said second ends of said crossarms being hingedly attached to said second arm at spaced locations thereon, said locations defining said first portion of said second arm, said second locations corresponding, respectively, to the locations on said first arm where said first ends of said crossarms are attached, such that said crossarms and said first portions of said arms intermediate said locations where said ends of said crossarms are attached form an adjustable parallelogram at said proximal ends of said arms;
- said second portions of said arms extending away from said paralleogram;
- each arm being hingedly joined to each of said crossmembers at locations on each arm which are offset from each arm;
- whereby said arms can be moved to and held in any one of the following three working relationships:
- (a) said arms are adjacent and parallel to each other with said distal end of one arm projecting forward of said distal end of the other arm so that said working implement at said distal end of one arm can be used alone,
- (b) said arms are adjacent and parallel to each other with said distal end of said other arm projecting forward of said distal end of said one arm so that said working implement at said distal end of other arm can be used alone, and
- (c) said arms are spaced from and parallel to each other with said distal end of one arm opposite said distal end of said other arm so that when said arms are grasped between said ends thereof and squeezed together, said working implements at said distal ends of said arms will be brought together so that said working implements can be used together.
