PLASTIEK-BOARD FIBROUS MATERIAL.
Specification of lIiettersjlatcnt. Patented hltl. 16, 1920.
Application led September 30, 1919. Serial No. 327,540.
Be it known that I, TREADWAY B. MoN- non, a citizen of the United States, residlng at Forest Glen, in the county of Mont-- gomery and State of Maryland, have invented certain new and useful Improvements 1n Plaster-Board of Fibrous Material;
and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates t0 a. plaster board of fibrous material and has for its object to rovide an article of this kind which will be ess costly to manufacture and more efficient.
in use than thosey heretofore proposed.
lVith these and other objects in view the invent-ion consists in the novel details of construction more fully hereinafter disclosed and particularly pointed. out in the claims. Referring to the accompanyingdrawings forming a part of this specification in which like numerals refer to like parts in all the views:
Figure 1 is a diagrammatic partly sectional view ofa plaster board made in,ac
' cordance with this invention;
Fig. 2 is a. cross sectional view of the parts shown in Fig. 1;
Fig. 3 is a View similar to Fig. plaster applied;
Fig. -it is a View similar to Fig. l of a somewhat modified form of the invention;
Fig. 5 is a cross sectional view of the part-s shown in Fig. 4;
2, with Fig. 6 is a view similar to Fig. 5 with the heat insulating qualities due to thehigher poroslty, glven by the slivers 2, sald insulite has long hair like fibers 3 which serve to bind together said sllvers 2. These fibers 8 are often one'or two inches long, and are say one one hundredth or one two' hundredth of an inch in diameter. f These said fibers 2 and 3 make an exceedingly porous mass, but it is loosely compacted, and has not a suiicient body to it. To remedy this defect, said insulite further is provided with short fine hair like fibers 4 which are say one vtwo hundredth of an inch in diameter, or smaller still, and say about onefourth inch long, or even shorter. These said fibers 4 serve as a filler for the mass, and may be associated 4with a substantial percentage of other filler fibers, such those usually employed in paper making. When the mass is constructed as above disclosed such a large quantity of air is entrained-'in the pores thereof that there results a board having not only an ab,- normal lightness and porosity but it possesses the lvaluable property of havin ab'- normal heat insulating qualities, and t ere- -fore, it possesses many of the physical characteristics of cork. In fact, such a board will seldom be found to have a specific gravity exceeding (14) four tenthsLand it often will be found to have a specific gravity not exceeding (.2) two tenths. It is readily pro duced in thicknesses greater than those possessed by other fiber paper boards, .and as the above mentioned fibers are truly felted together, during the manufacture of the board, said board -does not readily peel or flake off in layers as do paper boards.
The physical properties, and especially the abnormal and extraordinarily high heat insulating qualities of this particular insulite board, render it peculiarly adapted for walls of inexpensive buildings when stucco, cement, or' plaster isapplied thereto, but its unusually porous nature permits it to more readily absorb moisture than other paper boards, especially where the fibers are torn to provide recesses, or holding perforations,
for the plaster, stucco, or cement, as must be ico son of the fact that cement itself, as Well as Portland cement stucco, absorbes Water readily. Therefore, for this reason alone, it is very desirable to render the insulite material waterproof, but again, it has been found that if the waterproofing material extends throughout the mass of the insulite, it has a decided objection in that it reduces somewhat its heat insulating properties.
Not only does the cement or stucco material'readlly absorb water, as above stated, but 1t, owing to its alkahne character, at-
tacks the Wood pulp constituents of the insulite, and this attacking action i`s enhanced by the moisture which has been absorbed by the cement material.
To avoid these last mentioned` objections, instead of impregnating the insulite throughout its body with a waterproofing material, I coat only the outer surfaces of' said insulite material, with a Water resist-ing compound, such as tar, asphalt, pitch or boiled linseed oil. This coating cannot be applied by the usual process of dipping, etc., because, the very porous nature of the insulite material would cause the waterproofing material. to readily soak throughout the mass, and thus reduce the heat insulating properties, as
above mentioned, as well as Waste the Waterproofing material. Therefore, I spray the outer surfaces of' the insulite material, Wlth any suitable Water repelling material, such for example as a solution of asphalt and take care that the spray enters the perforations or recesses With which the body ofthe insulite is provided.
Accordingly, ,in carrying out this inven? l tion, I provide the body of insiilite 1, above mentioned, I further cut, mold or otherwise produce in said body, suitable recesses l plaster, cementfor stucco, 8 which fills said recesses 6 as shown, but which is nevertheless separated from the body of the insulite 1 by the waterproong material 7, as shown. In the modified forms of the invention illustrated in Figs. l, 5, and 6, the saine process is carried out, but the recesses or indentations 9 are of a different form from the recesses 6, shown in the preceding figures, and
further` they are pointed in different directions as indicated in dotted lines in said figures, for the purpose of giving ay better hold to the plaster material 8. It will now be clear that by providing the peculiar composition board known` as insulite, and by protecting its outer surfaces thoroughly from moisture, I am enabled to produce a plaster board which is free from the objections above noted, and which yet possesses the very high heat insulating qualities insiilite is known to possess.
It is obvious-that those skilled in the art may vary the details of the procedure as Well as the construction without departing from the spirit of the invention, and therefore, I
vided between said plastic material and said fibers with a thin layer of Water proofing material preferably sprayed onto said fibers, substantially as described.
A plaster board composed of sliver like fibers to give porosity, long hair like fibers to act as a binder, and short fibers to act as a filler,4 said body portion having a specific gravity less than .4: and possessing abnor' mally high heat insulating qualities; said body portion also provided with recesses in its surface, and with a layer of plastic mate rial having caustic properties entering said recesses; said body portion further provided between said plastic material and said fibers to prevent the caustic action of said plastic material vwith a thin-layer of water proofing material. preferably sprayedonto and not substantially penetrating the mass of said fibers. substantially as described.
In testimony whereof I affix my signature, in presence of two Witnesses.
