A further object consists in the adaptability of the improved construction to jig plates. 7
According to the invention the molders flask is constructed of two sheet metal cylinders concentric with one another and ar ranged a short distance apart so as to form an annular space between the cylinders. This space is filled with slag or'other suitable material, and in order to enable the material to obtain a firm grip on the sides of the flask, both cylinders and walls are provided with a series of perforations or recesses. The perforations are formed by stamping or in any other suitable manner so as to form or leave a projecting edge or flange aroundthe hole projecting into the annular space between the walls of the flask. Handles are. provided on opposite sides of the flask to enable it to be lifted. These handles are formed of round metal bar, split at one end for a portion of their length, the split ends being bent at right angles to the handle portion and embedded in the filling material. The walls are provided at opposite ends with guide pins and metal bushes or sockets respectively to enable the flask to register with corresponding pins or bushes arranged in or on an adjoining flask or mold ing plate or board.
The ends of the flask having bushes or sockets in its outeredge, may be provided with arecess or window above the end of the bush to enable the ,hole in the bush to be kept free of sand and facilitate the opera- Specification of Letters Patent.

The molding plate or board may be pro vided wlth clearance holes within which are placed gulde pins adapted to be locked when adjusted and in order to insure accurate adjustment of the guide pins, pieces of thin sheet metal may be fixed to the board marked with center lines.
The method of constructing the flasks may also be applied to the making of patternfframes or odd sides.
In order that my invention may be readily understood reference is made to the accompanying drawings showing several applications of'the invention by way of example, in which p V Figure l is a plan view of a molders flask. which may be used as a drag or a cone.

Referring to Figs. 1 to 4. a is the other casing and 7. the inner lining, both formed of sheet metal and arranged concentric with one another so as to form an annular space 0 between each wall. The annular space 0 is filled with slag or any other suitable mate rial. Each wall is provided with a series of recesses or perforations e punched, stamped, or otherwise formed from the outside of the outer casing and from the inside of the inner lining. The holes may be of any convenient size and are formed so as to leave inwardly projecting gged edges or flanges 6 hen the annular space is filled with the material. the edges of the recesses are {gm-l l enju:=a:l;lml while the outer surfaces of the' two walls present a comparatively cope is lifted off.

. In the construction shown'in Figs. 3 and 4,j b ushesfor sockets f are provided with a recess or window z above the inner end of the bush opening through the outer wall a so asto enable thehole in the bush t-o-be kept free of sand and facilitate the guiding of the flask onto a second flask or molding plate or board. p -1 r F'g. 5 shows a deep flask, "The inner walls 6 in this case are provided at each end 7 with an inwardlypi 'ojecting lip or flange 7c cutaway at a seriesfofequidistant points in its periphery to. receivethe loose barsor "45 arms Z shown in Fig. 6.
