COVERING FOR STEAM AND HOT-AIR PIPES.

' srsorricsrrox forming part of Beissued Letters Patent No. 9,318, dated July 27, 1880.

Original No. 221,695, dated January 20, 1880. Application for reissue June 14, 1880.

Be it known that I, ANDREW B. BATTELLE, of Bellairc, in the county of Belmont and State of Ohio, have invented certain new and useful lmprovelnentsin Coverings or Shields for Pipes and other Articles; and 1 do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon.

My inven ion relates to an improved covering or shield for confining the heat around steam-pipes and other "articles which radiate heat; and it consists. lirst, in the use and application of cotton-seed hulls applied 'to said pipes or other articles in the manner hereinat'tcr described; second, in a covering or shield I consisting-of the combination of cottonseed hulls and an outer casing; lhird, in a cover-- ing or shield consisting of the combination of cotton-seed hnlls and an inner and onter cas- I ing; fourth, in a covering or shield consisting a covering or shield consisting of cotton-seed o pipe and the inner casing of said covering or pipe.

bulls and an outer casing as applied to a steam- Fig. Zrepresents a covering or shield consisting of an inner and outer casing with raw cotton-seed hulls packed between said casings, said covering or shield being applied to a hot-air pipe' with anair-spac'e between said shiellL. Fig. 3 is a transverse section at line p.01 Fig. 2. Fig. 4 is-a perspective view of a suitable tool for packing-the cotton-seed hulls between the casings.

'ln'the accompanying drawings, in Fig. 1A represents the steam-pipc,-' B represents the cotton-seed hulls, and U the outer casing.

in Figs. 2 and 3 D represents, a hot-air pipe;

E, the inner casing; F, the outer casing, and G the cotton-seed hulls packed between them.

Theouter andinnercasing, when constructed of thin sheet metal, may be provided with a longitudinal-grooved seam or joint formed-by grooving the edges of the metal, so that they will hook into each other, as indicated at H in Figs. 1 and 3; and said casing may, if desired, be furnished with a bead or beads near the ends of each section of the casing, as indicated at I.

I proceed to give two examples in applying my covering or shield as applied to steam and hot-air pipes. Other applications of the covering or shield will readily suggest themselves to the skilled mechanic. As an example, in applying the covering to the pipes, l first take the sheet-metal casing,

which is usually in short lengths, about thirty inches long, and spring it apart at the seam suflicient to permit it to be placed over the steam-pipe.

Withv the aid of two or more clips on the end of the casing, I secure a uniform annular space between the casing and steam-pipe, which I fill with cotton-seed hulls, tamping the same aroundthe pipe with the tool J, made for this purpose. The elasticity of the metal and the pressure of the covering material hold thecasing together at the joint H.

When it isdesirsd to move the casing the sides are compressednear the joint sufliciently to unhookthe edges, when the casing can readily be taken olf- The mode of application of the double casing is practically the same, the inner casing having metal projections on its surface to keep it from'direct contact with the pipe. Whcn the covering is to be put on while the pipes in general. I

When desired to close the'end of the cylinder, 1 cut a round piece of sheet metal a little larger than the cylinder, turn a rim on h edge, cnt out a central opening the size of m .are being placed in position the double casing steam or hotair pipe, cut the ring thus iormed through one side and spring it over the steampipe and slip it on the end of the cylinder.

containing the covering. If required, a drop of solder will secure it in position.

In large pipes additional security can be obtained by means of bands of wire being placed a short distance apart along the cylinder. For hot-air pipes the double casing is peculiarly adapted, as it removes the covering material from direct contact with the hot-air pipe, and

thus pl events any possible char-ring of the material from undueheat.

The form of the covering or shield must in all cases be adapted'to the article to which it is to be applied, and in-hot-air pipes, or other articles which are frequently highly healed,

' there should be an air-space between the easing and said pipe or other article, at kin Figs. 2 and 3.

In the construction of a covering or shield for the purposes hereinbefore specified cottonseed hulls have the following advantages:

as indicated Lightness, non-conductibility', elasticity, practically nomcombustibility, contains natural oil, which prevents oxidation when applied to metals, cheapness, durability, adaptability to various forms, and can be removed from or placed in connection with pipes or otherthings, V

as a coveringor shield, with great facility.

Having thus described my invention, what I claim is 1. As a covering or shield for steam-pipes and other articles, cotton-seed hulls, applied substantially as herein described.

2. In a covering or shield for steam-pipes and other articles, the combination of cottonseed hulls and an outer casing, substantially as herein described.

3. In a covering or shield for steam-pipes and other articles, the combination of cottonseed hulls and an inner and outer casing, sung stantially as herein described.

4. In a covering or shield for steam-pipes and other articles, the combination of cottonseed hnlls, an inner and outer casing, and an air-space between said inner casing and the steam-pipe or other article, substantially as' herein described.

5. A eoveringfor steam and hot-air pipes,

composedxof an outer-casing of metal having 7 its edges bent so that they may be hooked together, and an interposed non-conducting filling of cotton seed hulls, all constructedand arranged substan tially as herein described.
