IMPROVEMENTS IN THE CONSTRUCTION OF BRICKS FOR BUILDING PURPOSES
Year: 1884

page_text: 1 HENRY HART of Ballymacarrow in the County of Down Ireland Gentle-
nan do hereby declare the nature of my invention for IMPROVEMENTS IN THE
CONSTRUCTION OF BRICKS FOR BUILDING PURPOSES to be as follows:-
I make these bricks with a longitudinal ridge or projection of any suitable shape
or size on one face of the brick (in preference along the middle) on the opposite
face is a corresponding groove or channel made so as to take in the ridge or
projection above described of the adjoining brick when laid. The tie bricks or those
to be laid across I construct with two similar ridges or projections but in a
transverse or opposite way to the others having also the two corresponding grooves
or channels on the opposite face thereof. These latter thus fit across portions of
two of those laid lengthways locking them together and producing a building of
great solidity with a mimimum of mortar or cement.

page_text: I HENRY HART of Ballymacarrow in the County of Down Ireland Gentleman, do
hereby declare the nature of my invention for IMPROVEMENTS IN THE CONSTRUCTION
OF BRICKS FOR BUILDING PURPOSES and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
I make these bricks with a longitudinal ridge or projection of any suitable shape
or size on one face of the brick in preference along the middle and on the opposite
face is a. corresponding groove or channel made so as to take in the ridge or
projection above described of the adjoining brick' when laid—The tie bricks or
those to be laid across I construct with two similar ridges or projections but in a
transverse or opposite way to the others having also the two corresponding grooves
or channels on the opposite face thereof These latter thus fit across those laid
lengthways locking them together and producing a building of great solidity with
a minimum of mortar or cement.
My Invention is more particularly illustrated in the accompanying drawing
wherein Figure 1 shows the end view of the brick constructed according to my
system Fig: 2 a side view of the same with ridge on the upper side and
corresponding groove or channel opposite as dotted Fig 3 is a side elevation of
the tie brick. Fig 4 shews an end view of the ordinary and tie bricks when laid
together as previously described.-Figures 5, 6 & 7 show bevilled arch bricks on
this system with ridges & grooves constructed as may be found most convenient for
the particular work in hand.-Fig: 8 is a front view of part of an arch in the
centre of which is a similar brick to that shown in Fig: 6, and Fig: 9 is a plan of
the top of such arch showing the firm arrangement of this ridge & groove system.―
I do not however confine myself to the exact form shewn as the ridges or
projections may be of any suitable shape the groove of course corresponding
there with and it will be found that these bricks_or_blocks-so-constructed will
produce a building-of-great-strength and is especially adapted for sea walls and
embankment faces which are exposed to the action of water.
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 the construction and use of bricks or blocks for building purposes having
the ridge and groove substantially as hereinbefore described and illustrated by the
accompanying drawing.
