Application filed June 14,
This invention relates to a refrigerator, and is particularly directed to a cast-stone refrigerator that may be entirely formed by one casting operation, and has for its object means whereby the inner shell and outer shell may be cast-united together.
In such a construction it is essential that the conductivity of the heat from the outside to the interior of the refrigerator be broken and means are provided for casting a heat insulating frame in the refrigerator, the inner and outer shells being both cast-united to said heat insulating frame.
i In the drawings:
F ig. l is a sectional View through the moulds showing how the fibrous strip mayy be iioated therein in preparation for the pouring operation. u
Fig. 2 is a similar sectional view after the cementitious material is poured in the mould.
Fig. 3 is a section taken on tie line 3 3 of Fig. 2.
Fig. l is a vertical section through the completed refrigerator taken on the line d-Ll of Fig. 3, the mould frames being removed.
Fig. 5 is a detailed plan view showing how the inner mould member which separates the inner shell from the outer shell may be held in place.
Fig. 6 is a detailed perspective view of the fibrous frame to which the inner and outer shells are cast-united.
a designates the outer shell which comprises side walls b, a. top wall c, a bottom wall Z and a front wall e.
The front wall is provided with a plurality of door openings The inner shell g is provided with a plurality of food chambers 7L, which are adapted to register with the door openings f in the front wall of the outer shell when the inner and outery shells are assembled together. A fibrous frame structure z' is provided with a plurality of door openings j which are identical in shape as the door openings f in the front wall of the outer shell.
I desire to pour the inner and outer shells with one pouring so that the ent-ire refrigerator shell may be made by one operation. As shown in Figs. l, 2 and 3, this would comprise a bottom base structure k and the side walls m which may be bolted to the base structure and to each other. This base 1924. seriai'ivo. 720,035.
structure is provided with the inwardlyeX- as at p is the intermediate mould niembers Q.
rThe fibrous frame i is floated within theV mould by means of the screws or other suitable devices 1 which are accessible from the inside of the core mand this securely positions the fibious frame so that the plastic cenientitious material may flow around the fibrous frame during the pouring operation. I provide a plurality of fastening devices, which are here shown as large-headed nails, which are driven part way into the fibrous frame. The mould partg is adapted to rest on this brous frame and', as shown in Fig. l, the mould is assembled together in readiness for the pouring operation.
Fig. 2 shows lhow the cementitious material is poured in the mould and how the moulding material fiows all around the fibrous frame member, the fastening devices being embedded in the stone work, thus securing the inner and the outer shells to said fibrous frame, thereby forming a refrigerator structure in which the' outer and inner shells are cast-united together to forni a rigid and strong unit.
The fibrous strips t are cast-united to the back Wall of the inner shell by the fastening devices u. I secure a back plate o to these fibrous strips carried by the inner shell by means of the fastening devices w. The fibrous strips a2 are floated in the mould, so that when the outer shell -of the refrigerator is poured these strips are located in the outer shell and the fastening devices z, here shown as nails, are driven through the back plate into this fibrous strip castunited outer shells for providing an insulating medium therebetween to positively break the conductivity of heat fromA the exterior to :the interio .f

5. In a refrigerator, the combination-of a moulded inner shell, anouter sh'elhand a vfibrous `frame to which saidshells are castunited for insulating the shells from eachV unitedto said'outer shell, and a moulded inner `shell 'provided with food chambers which registers with the door openings, said inner .shell cast-united to said-,fibrous frame.
V7. Infa refrigerator, the combination of a moulded outer shell provided with door i openings at the front, and integrally formed side Walls, a fibrous frame` having door openings of like size, the outer shell castunited to one side of said frame,. and a moulded inner shell cast-united to the other side of .said frame.
8. In a refrigerator, the combination of a moulded outer shell including side Walls, a ibrous frame cast-united to' the front of the outer shell andl to a part of the side waits, an inner shell cast-united to said fibrous frame and spaced from the side Walls ofthe outer shell, and means for supporting the inner shell at therear `thereof in such spaced relation with respect to said side Walls. y
