Description
I aiwa jll' ust describedis applied 1:; A. smrn, or Bananas, ctenrroamn.
. Wm nosnn mar access or sums m a v8o Ii -swims, Application flied September To all it may con/semi Be' it known that I, HENRY A. SMI fllH, a
. 1' citizen of the 'Uni'ted s'tatesf resid' at.v
Santa Barbara, in the countyof Santa I ar- .B bara and State of California, have invented new '/and u ful Improvements in Wall Boards and of which the following is a specification.
, My-inventon relates to wall board and l the pro'cesso making the same. I
' fvItiis'a bect of' thisinvention'to conlndoor-use, wich is inexpensive ofmanufacture, durable, and which is suitable for v1,5 the application of either aint or other coat- .in or plaster iindthelil er I y invention consists in the composition of the wall board and the process of makin the same hereinafter described and claime The composition is made as follows: as-
phaltum 15%, coarse sawdust 40%, wooden slivers of thesize and shaped broken tooth picks and sand 15%.
gIVBD. are by volume. v I W 'Theasphaltum 1s heated to a proximately,
350 R; and the sawdust an slivers ,are'
thoroughly mixed therewith. TheJhot as-v haltum mixed. with sawdust and-slivers as onto a moving so which is covered with a thin layer-o sand,
1 surface of the. hot mixture and a compression'rollei which reduces the] thickness of.
The layer to about five eighths' of'an inch passes over the same. It is essential that l vthe sand as well as the roller'be heated sufprevent the chilling ofw der of the asphaltum much arder. The
rocesses of Making the Seine,
ard suitable for outdoor and The quantities table so, 1920. Serial 1%. 413,902;
absorption of the volatile constituents by the wooden fibre hasa tendency to preserve the same and make it impervious to moistuie.
- In place of the sawdust,"slivers or straw a mineral fibre could be substituted, such as asbestos, although ordinarily the cost of; such mineralfib're is'prohibitive. The wall board prodiiced by my method;
presents a smooth surface, yet having sufclent roughness to take paint, either oil or cold water, readily, as-well as a coating of cement or plaster.
It will be understood that the present :invention is not concerned with the particular apparatus used. in making mywall boar but only the composition and method o making the same. n v, Various changes maybe made in the ess by those skilled in the art,=and the proportions of the ingredients'lmay likewise varied without departing fr nrthespirit of my invention as claimed.
'I' claim: v f I l, A recess'of making wall'boardcomprlsirig eating asphaltum to approximately 350? mixing sawdust andsh vers into: the asphaltum placing the mixedchihssupon a fmoving table covered with. a thin layer of sand, reducing the mass: onthe-table to about 1 two inches in thickness, applying a thin flaky slate preferred, to prevent the hot --ture from sticking to the table. The tlilck-v" ness of the layer ofthe hoth nixture applied. to the table is about two inches." Another 3 thin layer of. sand is placed on the upper layer-of sandjto the upper surface of the masspap lying. a compression roller which:
reduces-t I five-eighths of an inch,';kee pingthe sand and roller hotflto prevent chilling and cracking I delivering the. layer of asphaltum and san sion rollers; and passing thelay er between the compression rollers and thereby reducing the thickness to about thrm eighths of I an inch. I f i: I
'2. A process of making'wallboard comprisin eati 15% of; asphaltum to about 350 applying 40% of'co'arse' sawdust and 30% of wooden slivers'bf the size and shape of broken toothpicks and stirring the sawdust and slivers into the asphaltum thoroughly I thus producing a mass containin an'excess or almost an excess of saw "slivers, applyin I a thin layerofhct sand to a moving, ta 1e, applying the hot mix- .ture to the moving tab ejon top of the 1 sand to form a 1ayer, about'two inches I f thickness of the layerto about 1 I from the-moving table to a set ofcompres jtop oft thick, a-gplying a layer of hot sand to the 3. A wall boaid composed of 15% as- I compression roller over the layer an reducslivers, and 15% sand, the sand being aping theythickness; to about five-eighths of plied to the faces of the board. 1 l
