Abstract
A safety compass comprising first and second leg members. The leg members have a pivot opening and an arcuate slot formed in an upper portion thereof. The upper end portion of the leg members are pivotally attached together by a handle member having a pair of spaced apart side leaves that receive the upper end portions of the leg members therebetween. The leaves have horizontally aligned pivot openings and substantial vertical slots formed therein. A pivot pin member extends through the pivot openings formed in the leaves and the leg members. A guide pin member extends into and moves within the slots formed in the leg members and the leaves. A unique means is provided to retain a drawing implement. All of the component parts are preferably fabricated from a plastic material.
