Application filed February 14, 1910. Serial No. 543,838.
for use in refrigerator cars or other refrigk crating structures in which the tem erature 1s conslderably below the norma atmos- The object of the invention is to so construct a paper insulating sheet or structure having a multiplicity of air cells that the paper sheet havin said air cells shall be protected from molsture. i
The invention consists in the peculiar insulating sheet herein shown and described.
Figure 1, represents a plan view of a portion of a sheet of the new insulating material. .Fig. 2, represents an enlarged sec-- tional view taken on lines 2-2, Figs. 1 and 3. Fig. 3, represents an enlarged sectional view taken on lines.33, Figs. 1 and 2.
Similar numbers of reference designate corresponding parts throughout.
Insulating sheets or strips of the nature herein referred to are formed of paper and are used for the general purposes of'insulating chambers or compartments from the heat of the atmosphere. Said sheets may, however, be used ,to advantage as non-conductors of heat in or on any suitable structure.
In refrigerating cars or compartments the temperature is considerably less than that of the atmosphere and, consequently, the
Walls of said compartment become heated sufficiently to effect the condensation of moisture contained in the cooler air within the compartment. Such moisture attacks and, ultimately, will injuriously affect ordi nary paper insulation and particularly such insulation having air cells formed therein.
In carrying this invention into practice, I find that a satisfactory insulation may be formed by a compound structure formed by several layers of paper, one of which is furnished with'means for segregating a multi- 'plicity of'small bodies of air, and others of which 'form covers each common to all of the aircells. at one side of the cellular sheet, but such insulation in actual use attracts moistii're and the fibrous paper material absorbs such moisture and soon becomes pulpy and useless; tearing or falling away from its su'pportiugmeans arid leaving openings for heated air. v
AsshoWn in the drawings 5, represents the. cellular paper sheet having at each side a multiplicity of air cells 6, 6, formed by indenting or embossing said sheet: 7 7, are
outer sheets of waterproof paper which are secured to the ridges or boundaries of the .air cells 6, 6, by the comparatively thick coatings of asphaltic waterproof adhesive 8, 8, in which said ridges are partially embedded, said coatings 8, 8, being applied to the surfaces of the sheets 7 7 beforesaid sheets are brought-against the sheet 5.
' In insulation of, this character one object is to secure the insulating qualities of air by fur ishing means for segregating comparatively small bodies thereof, to avoid the circulation of the air. The more complete the layer of air surrounding the compartment to be insulated the more effective is the insulation and, therefore, the shape of the air cells 6, 6, is preferably such that the edges of the air cells at one side of .the sheet 5 overla the similar cells 6, 6, at the other side 0 said sheet so that, in effect, as to its insulating properties, the sheet 5 forms continuous unbroken means for segregating small bodies of air without breaking the continuity 0f the layer of air, while the waterproof covers 7, 7, with their asphaltic layers 8, 8, protect the sheet 5 from moisture.
Having thus described my invention I claim as new and desire to secure by Letters Patent. I
