1, MARK HENRY BLANCHARD trading as M. H. Blanchard & Co. of the Terra Cotta
Brick and Tile Works, Bishop's Waltham, Hants, Terra Cotta, Brick and Tile
Manufacturer, do hereby declare the nature of this invention to be as follows:-
The object of my Invention is the formation of bricks, for wells, for manholes to
sewers and similar purposes, in such a manner that the shape of the side of each brick,
forms a portion of the circular or other curvilinear outline of the well, sewer or other
structure that is to be built; thus obviating the necessity for hand cutting and
trimming, by which operation the brick is often fractured and made unsuitable for the
purpose for which it is intended to be used, and consequently causing a great waste of
material. One of the principal objects of my Invention is to overcome the defects and
disadvantages above pointed out. At the same time the material composing the
bricks, according to my invention, is of such density and corresponding co-hesive
strength as to resist great strain from the weight of superincumbent structure and
thus preventing disintegration from crushing.
According to my Invention, I construct the improved bricks by pressing or forcing
plastic clay, brick-earth or other suitable material through dies or moulds of a suitablo
size and shape, cutting or dividing the bricks vertically or longitudinally, or as may
be desired, by means of knives, wires, or equivalent methods; the curvilinear shape
being obtained by the dies or moulds before referred to. The blocks so formed are
then passed through suitable presses, actuated by hydraulic, steam, or hand power.
The clods may in certain cases be made entirely by hand labour, and the bricks can
be used without being pressed.
When the bricks aforesaid made in accordance with my Invention are laid in
cement or good mortar and applied for the lining of wells, the percolation of surface
water or other objectionable fluids is prevented from mixing with, or polluting the
water obtained from a lower stratum. Also when said bricks are used dry in building
a well, they are not liable to displacement, and the risk of accident arising from such
displacement is avoided.

page_text: I, MARK HENRY BLANCHARD trading as M. H. Blanchard & Co. of the Terra Cotta
Brick and Tile Works, Bishop's Waltham, Hants, Terra Cotta, Brick and Tile
Manufacturer, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by the
following statement :-
Hitherto in the manufacture of bricks such as are employed in the construction of
wells, the manholes of sewers, culverts, and similar applications, it has been necessary
to submit bricks used for said purposes, after same have been made, to hand cutting
and trimming in order to allow of same being adapted to the circular or other
curvilinear outline or configuration of the well or the like in the formation of which
said bricks have to be employed. Now said cutting and trimming frequently results
in fracture of, or otherwise in such injury to, the brick as to render same unsuited for
the purpose for which it was intonded to be used and consequently involves
considerable waste of material.
My present invention is mainly devised with a view to overcome the defects and
disadvantages above pointed out. In accordance with my invention, I make the
bricks to be employed in the construction of wells, the manholes to sowers, culverts
and the like, in such a manner that the shape of the side of each brick conforms with,
and constitutes a portion, of the circular or other curvilinear outline of the well, sewer
manhole or other like structure to be built.
In carrying out my invention I prefer to construct the improved bricks by taking
the clods of plastic clay brick-earth or other suitable material and forcing them
through dies or moulds of a size and shape to meet the requirements of the particular
application for which the bricks are to be used and I proceed to cut or divide the
bricks vertically, or longitudinally, or as will be desired; the curvilinear shape or
contour being imparted to said bricks as may be understood by means of the dies or
moulds aforesaid. I prefer then to pass the bricks so formed through suitable presses
to be actuated by hydraulic, steam or hand power.-I may however in certain cases
form the bricks when in a plastic state of the necessary contour or configuration
entirely by hand labor and dispense also with the pressing of same.
The material composing the bricks according to my invention, is of such density
and corresponding cohesive strength as to resist great strain from the weights of the
superincumbent structure and thus preventing disintegration from crushing-Further,
when bricks aforesaid made in accordance witn my invention are laid in cement or
good mortar and applied for the lining of wells, the percolation of surface water or
other. objectionable fluids is prevented from mixing with, or polluting the water
obtained from a lower stratum. Also when said bricks are used dry in building a
well, they are not liable to displacement, and the risk of accident arising from such
displacement is avoided.

page_text: 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:
In the manufacture of bricks to be employed in the construction of wells and the
like, the imparting to same in the process of manufacture and when in the plastic
state of the necessary contour or configuration so as to dispense with subsequent
cutting and trimming substantially as herein set forth.
