Improvements in Faced Bricks.
I, REGINALD HADDAN, of the Firm of Herbert Haddan & Co., of 18, Buckingham
Street, Strand, W.C., Patent Agent, do hereby declare the nature of this invention
a communication to me from abroad by Henry Rosenbaum, of the City of Cincinnati,
County of Hamilton, State of Ohio, and Michael Joseph Murphy, of the City of
Akron, County of Summit, and State of Ohio, in the United States of America,
both Merchants and Manufacturers, and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following state-
ment:-
This invention relates to a glass faced brick, block or slab, for the walls of
buildings, and for mantels vaults &c.
The primary object of the invention is to prevent crazing or cracking of the
facing, from the exposure of the facing to heat and cold and to varying atmos-
pheric conditions, and from blows or jarring from any cause.
With this object in view, and to the end of realizing other advantages hereinafter
mentioned, the invention consists in certain peculiarities of construction hereinafter
described and pointed out in the claims.
In the accompanying drawings, Fig. I is a view in perspective of a brick, block
or slab embodying the invention. Fig. II is a vertical section of the same, on either
one of lines II II Fig. I.
Referring to the drawings, A designates the body portion of the brick, block or
slab, that is composed of argillaceous or earthy material, and B represents the
facing, which is attached to the body portion. The facing upon its rear side, is
provided with two tongues or projections B1 B2 arranged a suitable distance apart,
and projecting into holes, grooves or recesses C formed in the body portion. The
body portion is provided with ingates D that communicate with the holes or
recesses C, and the cement G, employed in securing the aforesaid tongues within
the body portion, is introduced at the said ingates. The cement G should have two
characteristics, namely, toughness and the capacity of securing, or uniting, the
vitreous projections of the facing to the argillaceous or earthy body portion, and the
most suitable cement that has been found, for the purpose, is a sulphur compound
having arsenic as an ingredient. The sulphur and the arsenic, in the proportions
of one or two grains of the arsenic to one pound of the sulphur, are mechanically
mixed, and the compound is liquified by heat and poured into the aforesaid ingates,
whence it flows around the aforesaid projections and cements the said projections
to the body portions.
To attain the object indicated, in the second paragraph preceding the description
of the drawings, a layer K of expansible and contractible and elastic material,
such, for instance, as cork or rubber and preferably, powdered cork, is interposed
between and cemented to, the body portion and facing. The cement O, found
most suitable for attaching the said layer to the argillaceous or earthy body portion
and to the vitreous facing, is a glue cement having corrosive sublimate and
strychnine as ingredients, and this cement consists, preferably, of the glue,

page_text: corrosive sublimate and strychnine, in the proportions of about three grains of
strychnine and five grains of the corrosive sublimate to one quart of the liquid
glue, and made by mechanically mixing the strychnine and corrosive sublimate
with the liquified glue..
The method of assembling the parts of the brick, block or slab is preferably as
follows: The cement O, employed in attaching the clastic layer to the facing and
body portion, is brushed, firstly, upon the front side of the body portion, and the
elastic layer is then spread over, or placed-upon, the said side of the body portion,
whereupon cement O is brushed or spread upon the back of the facing, and lastly,
the facing is applied.
Very desirable results are obtained by interposing a layer of powdered cork
and Portland cement between the facing and body portion, in lieu of a layer com-
posed entirely of cork.
It should be observed, furthermore, that the thickness of the cement layers G
and and cork layer K are considerably exaggerated in the drawings in order to
more clearly illustrate the invention.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :-
1. A brick, block or slab having a facing, and a layer of expansible and con-
tractible material interposed between and attached to the facing and body portion.
2. A brick, block, or slab having a facing and a layer of elastic material inter-
posed between and attached to the facing and body portion.
3. A brick, block, or slab having a facing and a layer of expansible and con-
tractible and elastic material interposed between and attached to the facing and
body portion.
4. A brick, block or slab having a body portion composed of argillaceous or
earthy material, a glassy, or vitrified facing, a layer of expansible and contractible
material interposed between and cemented to the facing and body portion.
5. A brick, block or slab, having its body portion provided with a facing, and
a layer of cork interposed between and cemented to the facing and body portion.
6. A brick, block, or slab having its body portion provided with a facing, and
a layer of powdered cork between, and cemented to the body portion and facing.
7. A brick block or slab having a body portion composed of argillaceous or
earthy material, a glassy or vitreous facing, and cork between and cemented to
the facing and body portion.
8. A brick, block, or slab, having the following:-a body portion composed of
argillaceous or earthy material, a glassy or vitrified facing, and cork between the
facing and body portion and cemented to the latter and to the facing by a glue
cement having corrosive sublimate and strichnine as ingredients.
9. A brick, block, or slab, having the following:-a body portion composed of
argillaceous or carthy material and holes or recesses, a glassy or vitrified facing
provided with tongues or projections extending into the said holes or recesses and
cemented to the walls of the said holes or recesses by a sulphur cement containing
arsenic as an ingredient.
10. The method herein described of attaching a glassy or vitreous facing to an
argillaceous or earthy surface, consisting, firstly, in brushing or spreading cement
over the said surface; secondly, applying a layer of elastic material to the cement
bearing surface; thirdly, brushing or spreading cement over the back of the
facing and lastly applying the cement bearing surface of the facing to the elastic
layer.
