NON-CONDUCTING COVERING.
SPECIFICATION forming part of Letters Patent No. 683,514, dated October 1, 1901. Application filed February 25, 1901. Serial. No. 8,64=3. (No specimens.)
To all whom it may concern:
Be it known that 1, DAVID Q. STEPHENS, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Non-Conducting Coverings, of which the following is a specification.
The present invention relates to that type of non-conducting covering for steam-pipes and like uses in which layers of asbestos paper or like fabric constitute the body of such covering and is so formed or rolled as to provide a series of dead-air chambers or cells within the body of the covering to afford a better non-conducting or heat-insulating nature to the covering. The object of the present improvement is to provide a simple, cheap, and efficient arrangement and formation of such covering in which a large series of isolated air-cells are formed within the body of the covering, all as will hereinafter more fully appear, and be more particularly pointed out in the claims. I attain such objects by the construction and arrangement of parts illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a section of pipe-covering with portions of the layers composing the covering broken away to better illustrate the present invention Fig. 2, afragmentary longitudinal section of the same.
Similar numerals of reference indicate like parts in both views. 7
As represented in the drawings, the present covering will alternate layers of plain and longitudinally- corrugated sheets 1 and 2, of asbestos paper or other analogous material bent or formed into the required tubular or other shape and divided longitudinally, so as to permit of the application of the coveringsection to the pipe to be covered. Such construction is usual and common to pipe-covering heretofore in use, and no claim is made herein to suchformation nor to the outer casing 3 or the attaching-flap 4.
The present invention involves as the sole feature of novelty the provision, in connection with the alternate plain and longitudinally-corrugated sheets above described, of a series of short partition-strips 5, arranged in a direction transversely to the longitudinal direction of the corrugations of the corrugated sheets or layers 2 of the covering, the
corrugations being removed or cut away at such points to receive such strips 5. As so arranged the series of transverse strips will partition the extending longitudinal dead-air spaces formed by the corrugations into a series of separate and isolated air-cells to afford a very perfect insulating nature to the cover ing.
The scope of the present invention involves the described transverse arrangement of the partition-strips with relation to the longitudinal direction of the corrugations, and this whether the said corrugations of the sheets 2 extend in a longitudinal or transverse direc* tion in the section of covering.
In the manufacture of pipe-covering embodying the present invention it is preferable to form in the flat a duplex layer of plain and corrugated sheets with the transverse strips in place and then roll the said duplex layer up into a section of pipecovering of the required diameter and thickness.
Having thus fully described my said inven tion, what I claim as new, and desire to se cure by Letters Patent, is-- 1. As an improved article of manufacture, a non-conducting covering, formed of alternate layers of plain and corrugated sheets, combined with strips intersecting the corrugations of the corrugated sheets, to form a series of isolated dead-air cells within the body of the covering, substantially as set forth.
2. As an improved article of manufacture,
a tubular non-conducting covering having tiers of isolated dead-air cells throughout its body, said cellsbeing formed by superimposed sheets of material,each alternate one of which is corrugated, combined with strips intersecting the corrugations of the corrugated sheets, substantially as set forth.
3. As an improved article of manufacture, a tubular non-conducting covering having tiers of isolated dead-air cells throughout its body, said cells being formed by superimposed sheets of material, each alternate sheet being corrugated longitudinally, combined with strips intersecting the corrugations of the corrugated sheets, substantially as set forth.
Signed at Chicago, Illinois, this 20th day of February, 1901.
