" INSULATING-BOARD.
Specification of Letters Patent.
Patented May 2, 1911.
Application filed July 22,1910. Serial No. 573,235. 1
T 0 all whom it may concern: I
Be it known that I, SAMUEL Car-or, residing at Canton, in the county of Xorfoll: and State of Massachusetts, have invented an Improvement in Insulating-Boards, of which the following is a specification.
This invention relates to insulating boards adapted for refrigerating purposes, and also wherever an insulating board may be desired for heat or cold.
It has for its object to construct a board essentially of shredded wood, arranged in a promiscuous or tangled mass and adhesively secured together, and slightly but. not severely compressed and dried, whereby dead air spaces are formed in the board which @are permanently maintained; also to treat 'the board thus produced whereby 1t 1s substantially svatggp 'ggi galso to treatthe ,noard thus Touu ed wmreby it is substant'ially watt a )roof and fire-proof. rigu re l, shows a portioii' board embod ingthis invention. and. Fi 2, .l D
one of the shreds of wood.
a represents the shreds of wood, which are employed in tlmof the board. lVhile these shreds may be produced in any suitable manner, so far as my invention is concerned, they are easily obtainable at shingle mills, being a waste produced when sawing shingles and sometimes called shingle hair. In the manufacture of the board these shreds are formed into a promiscuous or tangled mass, so that they are more or less interlocked. yet separated sulliciently to form air spaces. This mass is then provided with a binding material havin; ad hesive characteristics. as for instance. it may be saturated with an adhesive solution for the purpose of adhesively securing the shreds together. Many adhesive solutions are. adapted for the purpose, but I prefer to employ a viscose solution. which made in any well known 01 suitable manner. ()l'dlnarily such solution may be made by taking cellulose ch as p p ck, and treating it with caustic soda and hi-snllid of carbon.
The bath into which the tangled mass of shredded wood is suluucrgrml may contain say. 5'. viscose. r m-h :1 solution is sullicicnlly adhesive to secure the shreds tom and is sulliciently alkaline to soften l l l l the shreds. The mass having been saturated with the viscose solution is dried and moderately but not severely com iressed. The pressure of the hand may e su ucl'ent but severe pressure acts to flatten the dead air spaces, so that the board loses a part of its insulating qualities. A viscose solution is especially well suited for this purpose for the reason that when dried it. secures the shreds together, yetholds them more or less separated in order that the dead air spaces formed in the board may be permanently maintained, and also permits the board to yield slightly to pressure.
If it is desired that the product shall be waterproof, the mass thus treated and having i s l i reds adh ';e l sec1 'ed together, at least sufliciently to manit ii iiTitEsliapeIKS then subjected to the action of a r i z i r o lggg zog p subsequent? to r. Fa lb o t?!luminum ulii tg a so ution of some other, substance, tending to iorm with the soap r sub stanceinsolublein.watcr- In case some other adhesive solution than viscose is employed, a difl'erent water-proofinn compound may be required.
In case it is desired to make the product substantially waterproof and lireqnooilhe product which is Hmipressed and dried may be subjected to a fire-proofing material. as for instance to a bath of anannngpiuurphos; .phate solution, approximately a 5, solution should suhice, or ammonium phosphate may be added to the viscose solution, and subse quently the mass treated with the waterproofing compound.
I claim I 1. The insulating board herein described 90 which is yielding) and ccllul:lr composed of a tangled mass of shredded wood, the shreds being adhesively secured together by a viscose solution, and the mass subsequently moderately compressed and dried.
.2. The insulating board herein described which is yieldingand cellular, composed of a fang-led mass of 'niixi'tltltil wood. the shreds being: ndhesirely secured together by a. viscose solution and treated with a soap and 100 aluminum sulfate. to render the board subslnulinllv waterproof.
3; The insulating board herein described which is vielding and cellular and substaln tially waterproof and fire-proof, composed of I In testimony whereof, I have signed my a tangled muss of shredded wood, the shreds name to this specification, in the presence of being adhesively secured together, and the two subscribing witnesses. mass being treated with a water-proofing SAHUEL CABOT. 5 compound and with a fireproofing com- 'itnesses: j
