Skeleton
A frame made by the pattern-maker from which, by the aid of outside and inside strickles, the loam-moulder constructs his mould without employing a full pattern. A convenient and cheap device for the production of tanks, condensers, etc., that are rectangular in form. Also, for moulding cylindrical objects, as steam-cylinders, etc., in loam. A skeleton-frame for this purpose consists of bottom and top flanges, in the rough, connected by a few lags vertically, which serve to fasten thereon steam-chest, feet, exhaust-belt, brackets, etc., at once, and thus obviate all possibility of the errors which frequently occur when these attachments are built separately into the brickwork. The skeleton-flange rests on the swept seating or guide-bearing. After the cope has been built to a template the screws are taken out from the inside, skeleton-frame taken away, and the loam swept on the surface by means of the spindle and sweep-board.
