MEANS FOR WATERPROOFING PIPE-COVERINGS.
Specification 01 Letters Patent.
Patented Sept. 22', 1914.
Application filed September 23, 1912. Serial No. 721,835.
To all whom it may concern:
Be it known that I, DUDLEY A. BoNrrz,
a citizen of the United States, residing at' Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Means for WVaterproofing Pipe-Coverings, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.
My invention relates to a means and method for waterproofing the coverings for steam pipes. Heretofore a great deal of difficulty has been experienced in providing permanent heat insulating coverings for steam and hot Water pipes, and the like owing to the fact thatno provision has been made in connection with such coverings to prevent deterioration of the same when water or moisture leaks through from the pipe or other sources and into the covering. The result has been that the covering has disintegrated more or less and become useless under the influence of the water or moisture.
My invention has to do with a method for waterproofing and steam-proofing the pipe covering so that, when Water does leak from the pipe or other sources, no damage will be done to the covering owing to the fact that such covering is provided with an inside surface which is impervious to the action of water, steam, or moisture.
My invention will be better understood by referring to the accompanying drawings in which- Figure 1 illustrates a pipe covering embodying the features of my invention, this covering being shown partly in section in position surrounding a pipe; Fig. 2 is a cross-sectional view taken on line 22 of Fig. 1; andFig. 3 is an enlarged cross-sectional View of the pipe covering.
As shown in Figs. 1 and 2, the covering comprises a plurality of sections, which sections are made up of semi-circular metal members 4, 4 which are rovided with side flanges 5, 5 and with end flanges 6, 6. The side flanges are bolted together by means of bolts 7 and, between these side flanges, there is disposed suitable cement 8. so as to make a Water-tight joint. The end flanges are bolted together by means of bolts 9 and, between these flanges, there is disposed a disk or diaphragm 10 which has a central opening 11 through which the pipe 12 extends. This diaphragm forms suitable supporting means for the covering, this arrangement providing a means so that the covering is supported concentrically or otherwise with respect to the pipe. On either face of the diaphragm there is spread suitable cement 13, 13 so that when the flanges 6 are bolted together, this cement will form a water-tight joint.
It is customary in connection with the arrangement I have shown to dispose suitable asbestos covering 14, which surrounds the sections and extends between the flanges. This asbestos covering may have surrounding it an outside covering 15, which may be of any suitable material such as asbestos or similar substance. It will be noted that there is an air space 16 between the sections 4, 4 and the pipe 12. This air space is large enough so as to admit the coupling of the pipe.
As is well-known in the transmission of steam through pipes, there is more or less leakage if the connections are not absolutely tight and this leakage of steam or moisture -'has the effect of deteriorating the asbestos covering and thus making it necessary to renew the covering at stated intervals.
My invention contemplates the provision of a covering which.is enameled or coated on the inside so as to render the coveringimpervious to the influence of water or moisture.,
As shown in Fig. 3, the metal section 4 is provided with an inside enameled surface 5 and the outside of the same may be provided With a similar surface 6. This enamel may be either painted on each section 4 or it may be otherwise applied. The object to be attained is to prevent the destruction of the covering when water or moisture is brought into contact therewith. Since each section is properly painted or coated and as there is cement between each of the sections, the water which may leak from the pipe cannot come into contact with the asbestos covering disposed on the outside of the sections 4 so that the asbestos covering is always kept in a dry condition, thus preventing deterioration of the same.
What I claim is:
1. A steam pipe covering comprising an enameled metallic sleeve surrounding the pipe and'formin awater-tight compartment, and a layer of eat-insulating material disposed on the outside of said sleeve.
2. In combination, a steam pipe, a metal sleeve mounted on said pipe and spaced therefrom to form av water-tight compartment, a glazed coating on said sleeve, and a layer of asbestos on the outside of said sleeve. v
3. In combination, a steam-pipe, a covering therefor comprising a plurality of metallic sleeve sections forming a water-tight compartment, each section having a coatlng of enamel and being provided with end flanges, spacers mounted on the steam-pipe and disposed between said sections, and means for securing adjacent flanges and the interposed spacer together, and a layer of asbestos on the outside. of said sleeve sections. 1
4. In a pipe covering, a plurality of tubular flanged sections having the interior surface thereof covered with a water proof coating of enamel, spacing members surrounding the pipe to be covered, said spacing members being clamped between the flanges of said tubular members to form a tight joint, and an asbestos cover surroundsaid end flanges of adjacent cylinders together, spacing members surrounding the pipe to be covered, said spacing members interposed between said end flanges, a coating of water proof enamel on the interior surface of said sections, said sections and said spacing members forming a water tight wall, and a cover of heat insulating material surrounding said wall to prevent heat losses.
In witness whereof, I hereunto subscribe myname this 21st day of September, A. D. 1912.
. DUDLEY A. BONITZ.
