COVERING FOR BOILERS.
SPECIFICATION formingpart of Letters Patent No. 231,832, dated August 31, .1880.
' Application filed June 28,1880. (No model.)
To all whom it may concern:
Be it known that I, TRUMAN IVIERRIAM, of Milwaukee, in the county of Milwaukee, and
in the State of Wisconsin, have invented certain new and useful Improvements in Coverings for Pipes, Boilers, &c. and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention relates to coverings for steam pipes and boilers, and is an improvement on the covering patented to me November 10, 1874.
In the drawings, Figure 1 is a top view; Fig. 2, a transverse section of a portion of the covering ready to be put on the pipe and Fig. 3 a transverse section of it as if in place on the pipe and finished.
I make my covering in sections by first wrapping a piece of asbcstus paper or board, A, abouta former, through which I pass a current of steam or hot air. I now cover its exposed surface with cement, and leaving flanges a a, Icover the cemented surface of the asbestus with a layer of hair felt or mineraLwool, B, of uniform thickness on all sides,
and about this felt or paper I wrap a layer of heavy paperfO, cemented on its inside, the paper and asbestus clasping the felt or mineral woollbetween them, and as the felt or mineral wool is made to adhere to the paper and asbestos by the cement, there will be no danger of its falling down in upright pipes to pack in the lower parts and leave the upper parts empty. Aboutthe paper I cement a layer of heavy cloth, D, covered with cement from a point directly opposite the flanges a, about three-fourths of the circumference of the covering, leaving flaps d d. I then place an outside former over the whole and allow it to remain until the section is dried, after which I take it off in perfect shape and in condition to be applied to the pipe by any intelligent workman, as follows: Draw the flanges a a sufficiently wide apart to admit the pipe between them, and slip the section onto the pipe. The elasticity of the covering will then cause the edges'to close together again. Press down the flap d, and cement it over the joint, and then (6' over that, when that section will be finished. The next section is put on in a like manner and the joint made air-tight by cement and cloth, and so on.
In covering for small pipe the asbestus, felt, or mineral wool should be cut clear through to the paper, and in very large pipes or boilers the asbestus, felt, or mineral wool and paper should be made in distinct longitudinal sections and united on the pipe or boiler by the cemented cloth.
about the boiler spirally to support the covering out from it.
Paste of any kind may be substituted for the cement in my covering without departing from the spirit of my invention, and instead of felt or mineral wool alone I may use both together, and instead of cementing it on only one side, I can cement the asbestos on both sides What I claim as my invention is 1. A covering for steam pipes, boilers, 850., consisting of an inner layer of asbestus paper or board and an outer layer of paper, both covered on their adjacent surfaces with ccment and clasping between them hair felt or mineral wool, in combination with an outer covering of cloth cemented to the paper and having overlapping flaps, as described, the whole shaped upon a former and dried, as set forth.
2. The covering for steam pipes, boilers, 850., consisting of the inner layer of asbestus having flanges a, a, in combination with the outer layer of paper, both cemented, as described, an intermediate layer of felt or mineral wool held in place by the cement on the paper and asbestos, and the outer covering of cloth having flaps d d, the whole shaped and dried upon a former, through which is passed a current of hot air or steam, as set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 17th day of April, 1880.
TRUMAN MERRIAM.
