MOORE AND KENNETH L. MOORE, 0F MUNCIE, INDIANA MOLDER S FLASK 1 vision of a simple and efi'ective means for con necting the flask walls, so that the flask may be readily assembled for use and thereafter knocked down or separated through the use of a small hammer or like tool or implement.

15 Another object of the invention is the provision of a novel form of partition bar which may be quickly secured within or removed from the flask, or may be adjusted to any desired position therein.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is a plan view partly in section showing a flask constructed in accordance with the invention.

30 Figure 2 is an elevation looking at one side 35 tively on the lines H and 5-5 of Figure 1.

Figure 6 is a fragmentary view showing one end of one of the walls of the flask.

Figure 7 is an edge view of the same.

Figure 8 is a view similar to Figure 6 but showing the end of another wall of the flask.

Figure 9 is an edge view of the flask wall shown in Figure 8.

Figure 1-0 is a detail perspective view of the assembling wedge.

Referring to the drawings in detail wherein like characters of reference denote corre sponding parts, the flask as shown includes a cope 10 and a nowel or drag 11 which are arranged in superimposed relation as shown in the drawings. The cope 10 and drag 11 are of like construction and comprise pairs of walls 12 of like construction and pairs of walls 13 also of like construction. The walls 12 and 13 may be made of various sizes and are interchangeable so that when the walls are connected in a manner to .be described, flasks of different sizes and shapes maybe made. The walls 13 are provided near each; end with transversely disposed elongated-open ings 14, the walls at each end of these openings being reinforced as shown at 15. Ex tending from the walls 13 are handles 16 by means of which the mold may be conveniently moved. These handles 16 may be replaced by centrally located trunnions for large flasks, so that the latter may be conveniently handled by a crane. In addition, thewalls 13 are provided with laterally extending apertured lugs 17 which receive locking pins 18, so that the cope and drag may be properly assembled. H p

Thewalls 12 have extending therefrom ears 19 which are provided with openings. 20, These ears are adapted to extend through the opening 14 to receive removable wedges 21. The walls 12 are provided with laterally ex tending lugs 22 which form shoulders adjacent the inner edges of. the openings 20 and these shoulders are adapted to abut one face of the walls 13, so that when the wedges 89 21 are arranged within the openings 20, these wedges will engage the outer faces of the walls13 and clamp these walls between the lugs and wedges. The outer walls of the openings 20 are inclined as shown at 23 to conform to the inclined faces of the wedges21.

It will be apparent from the foregoing description and accompanying drawings that the mold units may be quickly assembled, while a light blow from a hammer or other implement will remove the wedgesand permit of the separation of the mol V The cope is provided along opposite walls with longitudinally extending ribs 24. These ribs are adapted to be engaged by a partition bar 25 which is provided along one edge with spaced recesses 26 for this purpose. The other edge of the bar 25 is inclined as shown at 27 and pivotally secured to this end of the bar 25 as shown at28 is a member 29; This member is provided with spaced recesses 30' similar to the recesses 26 so as to engage one of the ribs 24 and in order to hold the member 29 and the opposite end of the bar 25 in such engagement, a wedge 30 is inserted between the member 29 and the adjacent beveled edge 27 of the bar.

The bar 25 may be adjustably raised or lowered, or it may be adjusted laterally to hold the sand within the cope.

From the foregoing description and accompanying drawings it will be seen that the invention provides a flask which is made up of inexpensive interchangeable units which are readily assembled or knocked down, so that from a stock of such units a number of flasks of different sizes may be assembled. When the flask is not in use the units may be disassembled and stored in a convenient place.

The invention is susceptible of various. changes in its form, proportions and 11311101 details of construction and the right herein reserved to make such changes as properly fall within the scope'of the appended claim.

Having described the invention what is claimed is o In a molders flask, separate pairs of side members and separate pairs of end members, each of said members defining an interchangeable unit,'one pair of said members having openings adjacent each end, ears extending from opposite ends of each of the other pair of members for passage through the openings of the first referred to pair, said ears also having openings therethrough, shoulders extending laterally from the ear carrying members adjacent to and parallel with said open ings to engage the other members between the openings and outer ends of said other members to engage the other members, and Wedges removably positioned within the open ings of the ears and also engaging said other members to clamp the latter between the shoulders and wedges and removably hold the parts assembled.

' In testlmony whereof we aflix our signatures.
