ysheets, each ply or layer being composed of a fiat orrelatively-smooth sheet of the material and a corrugated sheet thereofce' mented to one of its faces to produce deadair spaces.
'llhe particular construction of non-conducting material thus outlined is in extensive use, and isregularly manufactured in long sheets which are cut up into suitable lengthsimposed one upon the other to produce a'desired thickness for application to the insulating purpose, being rolled into tubular. form for use on pipes,I or provided in block -or other form for different other applications. h
'llhe primary object of my inventlon 1s to greatly increase the Inumber of airspaces in the material and also render them relatively small and thus more confining to the air they contain, with the obvious advantage of enhancing the insulating prop: erty of the material, and at the same time to-compactthe structure with the advantage of providing a relatively-large number of the layers and air-spaceswithout increasing the thickness of the material, to thus further enhance the insulating property of the latter.
lln the accompanying drawing, Figure 1 is an edge-view in section and -in somewhat exaggerated proportions, of a portion of a. layer of the aforesaid known insulating material, formed of a flat sheet of asbestos and a corrugated sheet of the same cement'ed thereto; Fig. 2 is asimilar view of the same', showing the corrugations folded upon themselves to produce my invention; Fig. 3 shows a plurality of the'layers of Fig. 2 imposed' one upon the other to produce my improved insulating material lin suitable thickness, and Fig. 4 shows, by a view in end elevation, the material of Fig. 3 reduced to 'tubular-roll, form, for pipe-covering but with the flat sheets and the corrugated sheets having the corrugations flattened down or folded, extending only partway about the tube-formation to simplify the' illustration.
ft flat sheet 5., preferably of asbestos, has cemented to one surface thereof a regularlycorrugated sheet also preferably of asbestos, to form between the two sheets deadair spaces 7, the two sheets constituting a layer, which is produced by suitable machinery in a usual way. I mash down -the corrugations, preferably by passing the layer between suitable rollers (not shown), thereby to fold them upon themselves all in the same direction into the condition clearly illustrated in Fig.`2, which is the preferred condition, though they may be otherwise mashed down, and not necessarily all in the same direction, without departure from my invention.
With the structure of Fig. 2 in a pile of layers, as represented in exaggerated form 1n Fig. 3, to provide my improved article in suitable thickness for its purpose, the spaces 7 are still present but are reduced in size, 4and between the folded end 8 of each corrugation and the fiat sheet 5 of the next layer another air-space 9 is formed, thus doubling the number of air-spaces in the structure and materially reducing them in size, by the flattening and folding of the corrugations, to more thoroughly distribute and confine the air-content throughout the structure and at the same time so compact the latter as to enable a relatively-large number of the layers to be used for a given thickness of the material, thus augmenting its insulating effect. Aswill be seen, the described construction produces two series of the air-spaces between each pair of the sheets 5, the members of the series being in staggered relation to each other.
1When the structure of Fig. 3 is formed into a tube, according to Fig. 4, for a pipecovering, to enable it to be spread for the application, it is split, as shown at 10, where flaps 1l, 11 overlapeach other of a fabric jacket l2 cemented about the tube as a finish therefor; and after adjusting the covering on a pipe and bringing the spread e'nds together, the flaps are cemented in their overlll@ As a new article of manufacturernonfderies of air-spaces between thevsuccessive cfnldcting nlllagerial oxrprislilng'a piuraty first-named sheets. o ayers eac orme o a s' eet o msu at- 4' ing material and a corrugated sheet of the ECIL M' CLARKE" :same secured to a surface thereof and hav- In presence ofng the corrugations folded upon themselves D.
