`.Application led January 2, 1926. Serial No. 78,796.'

To all whom t may concern: Be it known that I, JAMES' F. HINns, a citizen of the United States of America, and a lresident of Lakewood, in the county of 5 Cuyahoga and State of Ohio, have invented certain new and useful Improvements' in Mold'Containers, of which the following is a full, clear, and exact description.

So far as I amawaresnap flasks and jackets in use prior to my invent-ion have all been open to a variety of objections, principally the high cost of providing a permanently rigid flask or jacket having a finished interior, the inability to construct '15 a finished interior fiask or jacketwith rigid corners at a commercial cost, and the 1nability of any one flask or jacket to function yin all the various types of molding. My invention provides a mold container free from In the drawings accompanying this specification and forming a part of this application I have shown, for purposes of illustration, one form which my invention may assume, but I have illustrated this form, only as 'applied to the drag section of al ask since its application to the cope section of a fiask, or to a jacket, or to any other mold container, will be obvious from. the disclof sure relating to the fiask drag section.

In these'drawings:

Figure l represents a preferred method of forming the flask, while Figures 2, 3, and 4 show alternative forms of corner construction.

The present'application is a continuation in part of my copending application Serial Number 720,218, filed June 16, v1924.

In constructing the fiask drag section heren in shown Isfirst construct a form 3l, preferably madeof wood, and having its exterior of the exact form desired for the interior of the fiask section, and I then .assemble v aboutthis form 31 a pair of drag side plates 5 32' and a pair ofl drag end plates 33 of thel proper dimensions to exactly encircle the form v31 when their ends are tightly abutted, preferably formed of cast aluminum, having their inner-surfaces completely finished bemold container, wou d of course fore assembly, and each provided-at-eachend wlth a recess 34 arranged to communicate -and cooperate with the adjoining recess of the adjacent part. I then clamp these members 32 and 33 tightly in position about the form 31, close the lower ends of the recesses 34 in any suitable manner, as b resting the lform and members upon a suita lel flat plate,

and then pour into the recesses 34 molten metal 35 which may be lead or babbitt but it preferably the same material as the flask members and therefore preferably aluminum. I then maintain the members 32 and 33 in position about the'form 31 until the metal 35 isset after which the metal 35 is effective to firmly and fixedly permanently` 06 retain the members 32 and 33 together and form the members 32 and 33 into a unitary and integral flask drag section 36.

A jacket, or flask co .e section, or anyother be constructedf in the same `manner, but in con` structing; the sections of a flask I prefer to extend t e form -31 as shown and tov construct the additional sections about the same form above the drag section 36.

Undercertain circumstances I refer to form the corner joint as shown in i re 2 wherein each recess 34 is interrupte by 'a plurality of vertically spaced cross pins- 37 which are embraced bythe metal 35v and serve 80 as an anchorage toabsolutely prevent the metal-35 from pulling out `of the recesses 34. In other4 cases I find it entirel 'suiiicient to use the construction shown inl igure 3 wherein each recess 34 is interrupted byA a pluralit of vertically spacedlugs 38 u on which t e metal 35 may grip. In still ot er cases 'I- find it entirely safe to utilize the construction of Figure 4 whereinI' omit all interruptions'in the recesses 34 and'rely -solely'lupon the roughness 'of the-walls of the recesses 34, as cast, -to provide the desired, grip between .the members and the metal 35. Under certain circumstances it might alsobe` desirable to .taper the walls of the recesses 34 to provide a dove-tail construction but so .far Ihavenot found such a construction necessary and I' prefer.- to

omit it, as I`also prefer to omit the pins 37 and lugs 38' when possible, all in order to' reduce the costof manufacture.

' In actual practice, however, I find desirable eitherthe pins 37 or the lugs 38, pref.

- erably the pins 37, because byl interconnecting the interior and exterior walls l39 and 1,0 they permit these walls being made thinifer and therefore-lighter.

Afterv the mold containers have .been formed in this way any sand strip and registering devices and other accessories may be added `thereto in any manner found convenient.

From the above it will be obvious to those skilled in the art that I have disclosed herevin a mold container superior to anything lheretofore used. Itwill also be obvious to those skilled in the art that the-particularA embodiment of my invention herein shown" and described may be variously changed and modified without departing from the scope of my invention or lsacrificing thel admol vantages thereof.

It will therefore bel understood that the disclosure herein is illustrative only and that Vmy invention is not limited thereto.

I claim:

1. A joint securing'togethertwo substantiall non-integrated members of a metal container, comprising cooperating joint sections formed one-on each of said members, and abutting, and formed "to pro- .'vide a* recess between said sections, and a vmetal tie cast in said. recess and effective `alone to hold said members firmly and fixedly rigidly assembled.

.2. A ask section comprising a plurality of nonintegrated metal members' arranged in an annulus with each pair of adjacent ends abutted and containingfa .recess lying partly in each member, and metal ties cast ,1n said recesses l'and effective to hold said members firmly and xedly permanently assembled into a rigid flask section. v

3. A joint securing together two members i of a metal mold container, comprising, cooperating joint sections formed one on-'each of said members, and abutting, and formed to provide a recess between said sections, and a metal tie cast in said recess, and 'lying entirely exteriorlyof the inner walls of said 5./A flask section comprising a plurality iiswis ly and fixedly permanently assembled into a rigid flask section.

6. A joint securing together two members of a metal mold container, comprising cooperating joint sections formed one on each of said members, and abutting, and formed to provide` a recess between said sections elongated longitudinally of the axis of said joint, and a metal tie cast in said recess and vacting to hold said members firmly and fixedly rigidly assembled.

7. A joint securing together two members of a metal mold container, comprising cooperating joint sections formed one on each of said members, and abutting, and formed to provide a recess between said sections elongated longitudinally of the axis of said joint and lying partly in each of said sections, and a metal tie cast in said recess and acting to hold said members firmly and fixedly rigidly assembled.

8. A flask section comprising a plurality of metal members arranged-in .an annulus with each pair of adjacent ends abutted and containing a recess lying partl in each member and elon ated longitudinally of the junction of said members, and metal ties cast' in said recesses yand effective to hold said members firmly and fixedly permanently assembled into a rigid flask section.

9. The method of forming an all metal moldgcontainer which comprises forming a set of side Imembers each provided with joint sections each arranged to abut the cooperating joint section of-an adjoining side member, and toA form with said vcooperatingjoint section a recess lying between the two said joint sections, assembling said members with said joint sections abutted and said recesses formed, and, without substantially integrating said members, casting metal into said recesses to form ties acting to hold said members firmly and fixedly rigidly assembled.
