My claim as my invention, and what I desire to secure by letters patent, is for an improved core box for making sand cores for castings, having its parts well guided in opening and closing, and having cutting edges at their lines of meeting, so that no sand can be retained between them to revent their closing exactly, and fitted to be placed partly open when oosely filled with tempered sand, which is suitably compressed by closing the core box, and the surplus sand at the same time pared off and thrown out by the edges, and thus making the core uniformly solid or hard in all its parts, and of so exact form that the hole made thereby in the castin will in many cases need no “reaming;” thus making better cores, j with greater despatch, than have usually been made by “reaming up,” so termed by moulders and founders.

No. 4484.

I am cognizant of the fact that toggles have been constructed, wherein one was a long lever, jointed between its ends to one end of a short arm, constituting the other toggle, and which turned upon a pin or fulcrum at its opposite end, the power which operated the said toggles being applied to but one end of them, viz: the long lever. I do not claim such ; but that which I do claim is the extended levers I and G, as made and combined together, and having the power which operates them applied to both of “wondolins upon, them as above described.
