I found a plan for this jig in an old woodworking book, long before the days of power tools were the major factor in the wood shop. Made from scraps, it is held in the bench vise to securely hold two mitred parts such as a picture frame while a saw kerf is cut to take a spline.
Hopefully the pictures can provide you with a better description than my attempt at describing it. The batten affixed near the bottom assists in both holding it in the vise while allowing the mitred parts to,clear the jaws of the vise. The clamp bar rides on two trammels pins. Small springs on the bars (photo 3) provide a little tension when releasing the clamp bar. A butterfly nut is all that is required to hold the parts in place while sawing the kerf(s).
