L. A. BAN TA INSULATION STRUCTURE FOR REFRIGERATORS Filed Jan. 27. 1923 Patented Aug. 19, 1924.
UNITED STATES LEN ALBERT BANT'A, OF CLEARFIELD, PENNSYLVANIA.
INSULATION STRUCTURE FOR REFRIGERATORS.
.Application filed January 27, 1923.
To all whom it may concern:
Be it known that I, LEN ALBERT BANTA, a citizen of the United States, residing at Clearfield, in the county of Clearfield and State of Pennsylvania, have invented certain new and useful Improvements in Insulation Structures for Refrigerators; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in refrigerator structure and, more particularly, to an improved heat insulating panel structure for use in refrigerators.
Th object of the present invention is to provide an improved structure of the character indicated eliminating any direct contact between the interior surface of the panel and the exterior surface of the panel except through a plurality of independent interposed insulating and moisture retarding obstacles. Further objects will more particularly appear in the course of the following detail description.
The invention consistsin the novel construction, arrangement and combination of parts as hereinafter mor particularly described and claimed.
One sheet of drawings accompanies this specification as part thereof in which like reference characters indicates similar parts throughout.
The drawing is a fragmentary transverse sectional view taken through an improved panel adjacent one edge.
The present practice in refrigerator structure for large refrigerators and cooling boxes such as are used commercially by butchers and other dealers in perishable food stuffs is to construct such boxes or cooling chambers from a plurality of substantially identical panels constituting the side walls, bottom and top of the refrigerator respectively, said panels being joined adjacent their edges all of which is more particula-rl described in a co-pending application erial No. 615,329.
In such panel structures it is essential that no single part either of. wood or mtal should extend from the inside surface of the refrigerator to the exterior surface of the refrigerator as such direct connection permits the passage of heat by conduction. It is equally desirable that the passage of Serial No. 615,330.
moisture through said panels be efliciently retarded or prevented.
To accomplish the above ends I construct a refrigerator panel of an exterior or bottom face 1 of suitable timber and interior or upper face 1', said faces being spaced by marginal walls 2.
The structure can be best described in the steps of its manufacture in th course of which the outer face or plate 1 is covered with a sheet of waterproof paper 3 and then the marginal walls 2 secured in position by any suitable means (not shown). Waterproof paper 3 is then positioned circumferentially of the panel againstthe inner faces of the walls 2 and strips & secured in the corne formed between the face of panel 1 and the marginal walls 2 entirely surrounding the panel. Narrow strips of waterproof paper are then positioned circumferentially and interiorly of strips 4. Fibrous material such as granite rock wool 5, or, if desired, ground cork, is filled in to the height of strips 1, then a sheet of waterproof paper 7 is laid over strips 4 and the wool filling 5, which, in turn, is covered with a sheet of quilt fibre 6 and a second sheet of waterproof paper 7 and, if desired, a second sheet of quilt fibre and a third sheet of waterproof paper 7, as is illustrated. A second series of strips 4 are then positioned circumferentially of the panel and over the first layer of strips 4 and these, in turn, are seated and secured by nails or other suitable means not shown. Thereupon an additional filling of granite rock wool 5, is spaced to the height of the second tier of strips 4 and the process repeated as many times as may be desired.
It will be noted that, by reason of the structure thus described, there is no opportunity for conduction fromthe interior surface 1' to the exterior surface 1. Particular means for the prevention of the conductance of heat through the interior surface 1' are more particularly described and claimed in my co-pending application filed herewith.
Having thus fully described my invention, I claim:
1. An improved housing structure for refrigerators comprising a panel having an outer face and an inner face, said faces lined with waterproof material and secured by marginal walls abutting against said lined faces, waterproof lining for the inner face of said marginal walls and a plurality of tiers of heat insulating and waterproofing material between said faces and within the'marginal walls, each tier of heat insulating -material being surrounded by marginal waterproof covered strips and said tiers'of heat insulating material and their marginal strips being separated by sheets of waterproofing material.
.2. An improved structure for refrigerators comprising a panel having inner and outer wood faces joined by marginal wooden walls, a plurality of layers of neat insulating material between said faces, said layers being each surrounded by inner marginal strips adjacent the marginal walls and layers of felt and waterproof paper interposed between said layers of heat-insulating material, said faces, marginal walls and inner marginal strips having all their adjacent faces separated by and in close contact with waterproof paper.
