Description
W. R. GILLIES HEAT INSULATING TAPE Filed Sept. 22 1922 Patented Oct. 16, 1923.
UNITED STATES 1,470,723 PATENT OFFICE;-
WILLIAM R. GILLIES, OF CHICAGO, ILL
RUBBER COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
HEAT INSULATING TAPE.
To allwkom it may concern:
Be it known that I, WILLIAM R. GILLIES, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Heat Insulating Tape, of which the following is a full, clear, concise, and exact description, reference being had to the accompan ing drawings, forming a part of this specification.
My invention relates to a tape which is formed of a heat insulating material, and Which is adapted to be applied to fluid conducting pipes of various kinds. When the pipes to be insulated convey high temperature steam or hot water, the heat insulating material employed is preferably fire resisting, or, at least, capable of withstanding extremely high temperatures without disinte gration. The hereinafter mentioned forms of asbestos have proved excellent materials for my purpose.
My invention contemplates the provision of an improved tape which affords the requisite insulation, which, if necessary, is capable of withstanding high temperatures, and which easily may be applied tightly and smoothly to the pipe in connection with which it is employed, the tape being so con structed as to compensate for the unequal stresses to which the margins of the tape are subjected during the process of its application to the ipipe.
In the a'companying drawing illustrating m invention,
i igure 1 illustrates the manner of applying my improved insulating tape to a pipe;
Figure 2 is a transverse sectional View of the tape, and
Figure 3 is a transverse section illustrating the elements of the tape as they appear prior to the closing of the fabric tube or sheath.
In the drawing. reference letter,A generally indicates the insulating tape of my invention. B indicates a pipe to which the tape is applied, and C indicates devices for securing the tape upon the pipe.
The tape A consists of a flattened tube or sheath 1. which is preferably formed of a heat insulating and heat resisting material, such as a textile fabric, the woof and warp of which are in the form of cords of asbestos fibre. Disposed side by side within the tube or sheath 1, and extending continuously and Application filed September 22, 1922. Serial No. 589,787.
longitudinally therethrough, is a multiplicity of independent ropes 2 2, each of which is formed of asbestos fibre. Each of the ropes 22 may consistmerely of twisted asbestos fibres, or may consist of a number of asbestos cords twisted together to form a rope.
In the manufacture vention, the sheath 1 is initially in the form of a long. flat strip of asbestos fabric, as is.
best illustrated'in Figure 3. The ropes 22 are positioned upon and longitudinally of the sheatl1-strip, as shown in the last mentioned figure, and then the edges 1 1 of the strip are turned over the ropes and overlapped, as indicated in Figure 2. The overlapped portions of the sheath are then permanently secured together by heat resisting cement, such as silicate of soda.
In applying the tape to a pipe. that end of the tape which is first applied is preferably beveled a distance equal to approximately three times the diameter of the pipe. One wrap is then made around the ipe with the beveled end of the tape lying in a transverse plane of the pipe. The said end of the tape is then secured by means of a hose clamp or band of the type shown at C. The tape is then tightly and closely spiraled around the pipe the distance required. Additional clamps or bands C are preferably placed at intervals of from twelve to eighteen inches and assure a very neat and secure application of the insulating tape.
I have previously alluded to the fact that the flattened tube or sheath 1 contains a any suitable INOIS, ASSIGNOR TO UNION ASBESTOS &,
of the tape of my inmultiplicity of asbestos ropes 2-2. While a 1n the manufactured product, the ropes 2-2 lie very closely together and, so far as the matter of heat insulation is concerned, constitute a single body of asbestos felt, they retain their individuality to the extent that they yield to different degrees under the tensions to which the tape is subjected during the course of its application to the piping, and thus compensate for the unequal tensions to which the different margins of the tape are subjected during the spiraling operation. This construction enables the tape to fit the pipe very tightly and snugly, with exceptionally tight fits between the lateral margins of adjacent turns of the tape.
Having thus illustrated and described my invention. what I claim is new is:
An insulating tape adapted to be tightly sfiiralled about a pipe comprising a. flexible In witness whereof, I hereunto subscribe S eath consisting of a flattened tube formed --my name this 19th day of September, 1922. of a textile fabric of asbestos and a multiplicity of independent asbestos fibre ropes WILLIAM GILLIES' 6 disposed side by side and longitudinally of Witnesses:
