I, JOHN HENRY WILLIAMS STRINGFELLOW, of Canal-side Works, Andrews Road,
Hackney, in the County of Middlesex, Engineer, do hereby declare the nature
of this invention to be as follows:-
My invention relates to the production of a compound material having water-
proof and acid-proof properties, which is capable of being applied to numerous
purposes in the industrial arts, in the form of sheet, rod block, casing and other
forms required for use.
The objects of my invention are attained by forming a material composed of
vitreous or silicious matter such as ground glass, flint, pumice and like material,
with a binding or cementing agent of carbonaceous or hydro-carbonaces matter,
such as pitch shellac bitumen india-rubber gutta-percha, or other substitutes, to
which compound is sometimes added organic matter such as paper peat-fibre or
other material in suitable form, or inorganic matter like asbestos fibre or any
substitutes for same which are calculated to act as chemical and strengthening
agents.
a
My invention is applicable to the following amongst its many uses. Namely--
As a compound capable of being produced in either a flexible or non-flexible
form and of being used either with or without combined fibrous and other
strengthening and chemically acting matter; which compound may be made
plastic and then pressed, rolled, cast, or otherwise made into sheet, rod, block,
case, tube, or other form desired. b. As a compound capable of being brought to
a state for, and into which any kind of natural or manufactured material or
body such as wood, asbestos, stone, brick, leather, canvas, millboard, strawboard,
or other suitable material, may be immersed, to be more or less penetrated by
penetrable properties of the compound, and to be more or less coated with the
encasable properties of it. °. As a compound capable of being superimposed upon
a metallic framing, sheeting or groundwork such as a skeleton-frame, wire-work,
expanded-metal, metal-casting or other structure; whereby metallic strength
combined with resistance to acid, atmospheric, watery and other influences is
obtained. That is to say, the compound may be made to act either as a casing to
the several parts of such metallic structures, or as a combined casing of same
and as a filling of any interstices desired. For example. A piece of wire-netting
may be encased as to the wire, and the meshes be filled in, so that it becomes a
solid sheet of water-proof or acid-proof material, suitable either for constructional
work, or for covering a floor, a roof, or lining a cistern or wall, or other appli-
cations; with the capability of joint cementation as butt-joint or lap-joint. It is
therefore able to fulfill the objects of calcareous and hydraulic cements and lead,
zinc, and the like, as a protecting material where desirable.
The carrying out of my invention would be effected as follows. Namely, by
one method. Into a suitable vessel I put one part by weight of any suitable
hydro-carbon, say common pitch, and when this is melted, I add one part by
weight, equal to the pitch, of pulverized glass or other suitable silicious matter.
When this is sufficiently incorporated and in a fluid state, I immerse in the
compound a sheet of suitable material, say asbestos, which I then by any avail-
able method form into a box case or cylinder as may be required, which is not

page_text: affected by sulphuric acid or water, and which is adaptable for cheap and efficient
electric-battery cases and other uses. Another method would be by using the
above compound alone, then again by adding to it whilst in a melted state, asbestos
fibre in the proportion of one eighth the weight of pitch contained in the com-
pound, and after suitable working and incorporation to put the whole into a
suitable pressing chamber or other vessel, and then by any suitable mechanical
appliances to force or work the compound into a mould or through dies, or a
combination of both, whereby a box, case or cylinder would be produced, of
similar form and shape to that producible by the other method described, and
capable of being used as an electric battery-case or for other purposes. Either of
the before described methods are also adaptable to produce lids of boxes, rims.
feed-sockets, caps, stoppers and other fittings, by variations of the mechanical
moulds and appliances. When flexibility or increased tenacity is required, a
more or less flexible hydro-carbon is selected for the cementing matter, and the
other components of the compound may be likewise adjusted in the usual well-
known methods of chemical working. The flexible hydro-carbon may be gutta-
percha, india-rubber bitumen or other matter possessing suitable properties.
It is self evident that the invention is adaptable to electrical and innumerable
other purposes and in many ways. Also that the compound is capable of being
varied to meet different requirements, by varying the descriptions and propor-
tions of the vitreous or silicious or hydro-carbon or other materials used as
described. For example. Suitable compounds may be formed and then be drawn
or pressed into suitable or continuous lengths of rod, tubing, sheeting, moulding
or other goods required. Also that wrought, or cast-iron rods, bars, tubes, main-
pipes and other goods in these or other metals may be cased inside or outside.
Then the compound in a suitable form may be used for jointing, for constructing
and for repairing, or cementing various things in various kinds of material, such
as metal stone, glass, wood and others.. Then when the compound is not to be
subject to the action of acids a wider range of silicious material may be utilized
than otherwise.

COMPLETE SPECIFICATION.
Improvements in Waterproof and Acid-proof Compounds.
I, JOHN HENRY WILLIAMS STRINGFELLOW, of Canal-side Works, Andrews Road,
Hackney, in the County of Middlesex, Engineer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
My invention relates to the production of a material having waterproof and
acid-proof properties which is capable of being applied to numerous purposes in
the industrial arts.
The objects of my invention are attained by mixing vitreous or silicious matter,
such as ground glass, flint, pumice, and like material, with a binding or cementing
agent of carbonaceous, or hydrocarbonaceous, matter, such as pitch, shellac,
bitumen, india rubber, gutta percha, or other substitutes, to which compound is
sometimes added organic matter, such as paper, peat fibre, or other material, in
suitable form, or inorganic matter, like pumice, asbestos fibre, or any substitutes
for same which are calculated to act as strengthening agents.
In carrying out my invention, I may proceed as follows:-I place in a suitable
vessel a quantity of any suitable hydrocarbon, say, common pitch, and subject it to
heat. When this is melted, I add an equal weight of pulverized glass, pumice, or

page_text: other suitable silicious matter, keeping up the heat whilst adding it.
When
this is sufficiently incorporated, and while in a fluid state, I immerse in the
compound a sheet of suitable material, say, of asbestos millboard, which is then
withdrawn and rolled down, or otherwise reduced to a required gauge of thickness.
from which boxes or cases may be produced in any convenient manner. Or the
sheets may be applied to produce cisterns tanks, tubing, or as linings or outside
casings to same, and to such other purposes as it may be adaptable to, for giving
acid-proof or water-proof results.
When flexibility or increased tenacity is required, a more or less flexible hydro-
carbon is selected for the cementing matter. Such flexible hydro-carbon may be
gutta percha, indiarubber, bitumen, or other matter possessing suitable properties.
Also the rubber may be vulcanized when necessary.
The invention is adaptable to electrical, and innumerable other purposes, and
in many other ways. The compound is capable of being employed for different
requirements by varying the proportions and kinds of vitreous silicious, or
hydrocarbon or other material used. Wrought or cast iron rods, bars, tubes,
main pipes, or constructional work, in any metals, may encased or lined by the
material produced under the invention, so as to render such metal acid-proof and
water-proof.
My invention is applicable to the following, amongst its many uses, namely, as
a compound capable of being produced in either a flexible or non-flexible form,
and of being used either with or without combined fibrous and other strengthening
material, and chemically-acting matter, which compound may be made plastic,
and then be pressed, drawn, cast, or otherwise made into sheets, rods, blocks.
cases, tubes, or other form desired. As a compound capable of being brought
by heat to a more or less fluid state, for, and into which, any kind of raw or manu-
factured material or body, such as metal, wood, asbestos, stone, brick, leather,
canvas, ordinary or asbestos millboard, strawboard, or other material, may be
immersed, so as to be more or less penetrated and encased by the respective
properties of the compound. As a compound capable of being superimposed upon
skeleton metal or other frame-work, such as wire-work. expanded metal, castings.
stamped metal, or other basis, whereby metallic and mechanical strength, combined
with resistance to acid, water, atmospheric, and other influences, is attained. For
example, wirework so covered would form slabs or sheets adaptable for covering
floors, walls, roofs, and the like, or for building tanks, which material would
possess the advantage of readily-made jointing of an effective kind at little
expense.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
:-
1. A waterproof and acid-proof compound or material, composed of vitreous
or silicious matter and a suitable hydrocarbon or carbonaceous cementing material,
with a strengthening addition of organic or inorganic material, as herein described.
2. The manufacture of water-proof and acid-proof slabs or blocks as herein
described, & for the purpose set forth.
3. The use of the water-proof and acid-proof compound, or slabs or blocks
produced therefrom, in the manufacture of boxes & cases and for other purposes,
as herein described.
