INSULATING MATERIAL AND PROCESS OF MANUFACTURING SAME.

JULIUS DE LONG, OF LAKE MAHOPAC, NEW YORK.
INSULATING MATERIAL AND PROCESS OF MANUFACTURING SAME.
Application filed April 26, 1922.
To all whom it may concern:
Be it known that I, JULIUS DE LONG, a citizen of the United States, residing at Lake Mahopac, in the county of lPutnam and State of New York, have invented new and useful Improvements in Insulating Materials and Processes of Manufacturing Same, of which the following is a specification.
My invention relates to improvements in insulating material which are particularly adapted for use in insulating railroad cars, buildings and other structures, and the objects of my invention are to produce a new insulating material which can be cheaply and economically manufactured, which will be essentially fireproof in its character, and which is a far betternonconductor of heat than the previous types of fireproof insulating material heretofore in use, and which also possesses sufficient rigidity to be easily handled and applied.
Reference is hereby made to the following pending applications by the applicant relating to the same or kindred subject matter, namely: Serial No. 432,649, Serial No. 517,923, and Serial No. 591,362.
Figure 1 is a perspective view of my insulating material with the layers of the material used partly broken away.
Figure 2 is an enlarged sectional view on the line XX of Figure 1.
In the drawings, 1 indicates the woven fabric; 2 the bats of asbestos fibre and cattle hair, and 3 the covering of asbestos paper.
Heretofore fireproof insulating material has been made from asbestos fibre, but in this type of insulating material the fibres were always secured together by glue or other adhesive. material which tended to close and fill the air spaces between the fibre and thereby greatly decreasing the insulating value of such insulating material. Insulating material has also been formed by mingling asbestos fibre and cattle hair, but in the past these fibres have also been secured together by means of glue or other adhesive material which tended to fill the air spaces between the fibres and detracted from the insulating value of the material so formed. Material so formed is also liable to disintegrate and fall apart when damp or wet and therefore is undesirable for many purposes for which insulating material is used.
I have found that I can make a strong,
Serial No. 556,579.
durable and more nearly fireproof insulat- 111g material by the following process:
I run finely divided asbestos libre and cattle hair through a picker and form the commingled asbestos fibre and cattle hair into bats by running it through a chine. I lay a bat so formed upon a strip of fireproofed burlap or other suitable noninflammable Woven fabric possessing the desired strength and run the bat and burlap through a punching needle loom, the needles of such loom forcing the asbestos fibre and cattle hair through the woven fabric and interlapping the fibres of asbestos and cattle hair with each other and firmly securing the bat to the woven material. lVhen this operation is completed I turn the product over and place another similarly formed bat upon the exposed surface of the woven fabric and again run the material through the punching needle loom with the result that the fibres of asbestos and cattle hair in the upper bat are interlocked, and the fibres of the upper bat are driven through the woven fabric and more or less interlocked with the asbestos fibre and cattle hair on the opposite side and the woven fabric. This produces a strong, durable felt which is a better nonconductor of heat than the material heretofore used and is at the same time essentially fireproof.
I prefer to use substantially equal quantities of asbestos fibre and cattle hair as this produces material which is strong, durable and essentially fireproof. These proportions may be varied, however, without departing from the spirit of my invention. Where burlap is used I treat the burlap with a solution which renders it flame proof.
Where a rigid material is required, I ap- Ely adhesive material to the surface of asestos paper or other suitable covering which I apply to one or both of the outer surfaces of the felt formed as above stated. \Vhere asbestos paper is so applied and particularly where it is applied to both sides of the felt the insulating value is increased because of the dead air trapped bet-ween the sheets of asbestos paper and the material possesses sufiicient rigidity and strength to be easily handled and applied.
Having described my invention, I claim:
1. An insulating material comprising in combination noninflammable woven fabric. bats composed of asbestos fibre and cattle hair on each side of said noninfiammable carding ma- Woven fabric, the cattle hair and asbestos fibre in each bat being interlocked with each combination noninfiammable woven fabric,
bats composed of asbestos fibre and cattle hair on each side of said noninfiammable woven fabric, the cattle hair and asbestos fibre in each bat being interlocked with each other, with the noninfiammable woven fab- I ric and with the asbestos fibre and cattle hair 0f the bat on the opposite side of such noninfiammable woven fabric, and an asbestos covering on each side thereof and secured thereto by adhesive material. 7
3. An insulating material comprising in combination noninfiammable woven fabric, bats composed of asbestos fibre and cattle hair arranged on opposite sides of such noninflammable Woven fabric and secured to each other and to such noninfiammable woven fabric by interlocking the asbestos fibre and cattle hair of each bat with the asbestos fibre and cattle hair of the other bat and with such noninfiammable woven fabric.
4. An insulating material comprising in combination noninfiammable woven fabric, bats composed of asbestos fibre and cattle hair arranged on opposite sides of such noninflammable woven fabric and secured to "each other and to such noninfiammable woven fabric by interlocking the asbestos fibre and cattle hair of each bat with the asbestos fibre and cattle hair of the other bat and with such noninfiammable woven fabric, and an asbestos covering on each side thereof and secured thereto by adhesive material.
5. The process of making insulating material consisting of (1) passing asbestos fibre and cattle hair through a picking machine, (2) forming the product thus obtained into a bat by passing the same through a carding machine, (3) arranging the bat so formed on noninfiammable woven material and securing the bat to the noninfiammable woven material by passing both through a punching needle loom, (4) placing a bat formed as above stated on the opposite side of the noninfiammable woven fabric and running the same through a punching needle loom.
Signed at New York, this 17th day of April, 1922.
