IMPROVEMENTS IN THE CONSTRUCTION OF WALLS WITH LOUVRE
Year: 1884

page_text: I, JOHN CHAMPNEY BOTHAMS of Church Field Road in the Parish of Fisherton
Anger in the county of Wilts, Civil Engineer do hereby declare the nature of said
invention for IMPROVEMENTS IN THE CONSTRUCTION OF WALLS WITH LOUVRE
"to be as follows:-
OPENINGS AND BRICKS OR BLOCKS FOR THE PURPOSE
25
The object of my invention is to facilitate the building of walls with louvre
openings by forming bricks or blocks in such a way that when they are placed in
situ alone, or in conjunction with tiles the required openings will occur; their
number depending on the form arrangement and number of bricks or blocks
employed.
For this purpose I make such bricks with inclined perforations and recesses, or
either, substantially as I will now proceed to describe with reference to the
accompanying sheet of drawings which I give by way of illustration to facilitate
a clear understanding of the nature of my invention.
Fig 1 shews in front elevation a brick wherein the front or outer side as also the
back or inner side are formed each with a recess a. the one being in the upper part
as shewn in cross section of two such bricks at a Fig 2, and the other recess being
in the lower part as at b. b.
Referring to Fig 2 it will be seen that the two bricks when placed together one
above another form a louvre or slanting opening between them. In Fig 3 each
brick is formed with only one recess-the recess a being in the front top part of
the one, and the recess b in the back bottom part of the other so as to produce an
opening and omit an opening at the alternate joints as required, or the openings
may be at greater intervals apart if solid bricks be interposed.
Louvre Bricks or part bricks for bonding with others may be made as represented
in Figs 4, 5, 4, 5ª. In the arrangement, Fig 4 a part may be taken out of the
under side at one or both ends and in the arrangement Fig 5 at the upper side at
one or both ends, or the part may be taken out from both under and upper sides
at one or both ends; and in Fig 6 two such bricks as represented in Fig 4 are
shewn, the taking away of the parts c. and a forming with the under brick a
louvre or slanting opening.
These bricks may be built together to form tops to chimnies, leaving in the sides
or ends, louvres or openings slanting upwards from the outside, as shewn in Fig 7
in elevation and in Fig 8 in section.

page_text: The openings may be of any size, form or number and the opening may be
formed through one brick or through two bricks as in Fig 2 or through three
bricks as in Fig 9.
Or the bricks may be formed with one or more inclined recesses or grooves.g in
one or both ends as in Fig 10, or in one or both sides as in Figs 11 and 12, and in
these grooves may be placed tiles, discs of slate, glass or other material as at f. f.
Fig 13. or Louvre tiles as at f Fig 14.
The Louvre bricks or blocks and Louvre tiles may be made of the same
materials as ordinary ones, or of terra-cotta, stoneware, concrete or other suitable
material, and of any size; those shewn in the drawing being designed to work in
with ordinary bricks.

page_text: I, JOHN CHAMPNEY BOTHAMS of Church Field Road, in the Parish of Fisherton
Anger, in the County of Wilts, Civil Engineer, do hereby declare the nature of my
invention for "IMPROVEMENTS IN THE CONSTRUCTION OF WALLS WITH LOUVRE
OPENINGS AND BRICKS OR BLOCKS FOR THE PURPOSE "
and in what manner, the
same is to be performed to be particularly described and ascertained in and by
the following statement :—
The object of my invention is to facilitate the building of walls with louvre
openings by forming bricks or blocks in such a way that when they are placed in
situ alone or in conjunction with tiles, the required openings will occur, their
number depending on the form, arrangement, and number of bricks or blocks
employed.
For this purpose I make such bricks with inclined perforations and recesses or
either substantially as I will now proceed to describe.
Referring to the accompanying sheet of illustrative drawings, Fig 1 shews in
front elevation a brick wherein the front or outer side, as also the back or inner
side are formed each with a recess, the one being in the upper part as shewn in
cross section of two such bricks at a. a Fig 2, and the other recess being in the
lower part as at b. b. Referring to Fig 2 it will be seen that the two bricks when
placed together on one another form a louvre or slanting opening between them-
In Fig 3 each brick is formed with only one recess, the recess a being in the front
top part of the one and the recess b in the back bottom part of the other and so on
to produce an opening and omit an opening at the alternate joints as required, or
the openings may be at greater intervals apart if solid bricks be interposed.
Louvre bricks or part bricks for bonding with others may be made as represented
in Figs 4, 5, 6, 7.
Fig 4 represents in front view a brick having formed in the back of its lower
portion two recesses, one at each end, these recesses being (as seen in cross section
of the brick) of similar form to the recesses b in Figs 2 and 3. In some cases the
brick may have such a recess at only one end. Also instead of being in the back
under part such recess or recesses may be in the top front part as represented in
Fig 5 where two recesses a a are shewn-or there may be at one or both ends
recesses in both top and bottom parts. Fig 6 represents a half brick or block
recessed at one end at the back (bottom) and Fig 7 a similar half brick or block
recessed at one end at the front (top)-Fig 8 is a front elevation of the
arrangement represented in cross section in Fig 3. It will be seen that the
recesses form louvre or slanting openings as is clearly shewn in the cross section
Fig 3.
These bricks may be built together to form tops to chimnies leaving in the sides
or ends louvres or openings slanting upwards from the outside as shewn in elevation
and in section respectively in Figs 9 and 10 which illustrate a chimney top
constructed with my improved bricks or blocks according to the invention forming
the subject of another application for Letters Patent made by me bearing even
date herewith and numbered 5222 and which invention I do not here claim.
The louvre openings may be of any size, form or number, and the openings may
be formed through one brick as in Figs 20 and 21 or through two bricks; or
through three bricks as in Figs 11, 12 and 13 Or the bricks may be formed with
one or more inclined recesses or grooves g in one or both ends as in Fig 14 which
shews two bricks in end view, or in one or both sides as in Figs 15 and 16 and in

page_text: these grooves may be placed tiles, plates, or sheets of slate, glass or other material
as at ff, Fig 17, or louvre tiles such as shewn in Fig 18 and in cross section at ƒ. ƒ
Fig 19.
The louvre bricks and louvre tiles may be made of the same materials as ordinary
bricks and tiles, or of terra-cotta, stoneware, concrete or other suitable material
and of any size, those shewn in the drawings being designed to work in with
ordinary bricks.
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 The use for constructing or building walls with louvre or slanting openings
of bricks or blocks formed, with recesses or passages therein or therethrough
substantially in the manner hereinabove described.
2, The construction of walls with louvre or slanting openings by the use of
bricks or blocks having inclined recesses or grooves in conjunction with tiles or
plates or sheets of suitable material such as glass or slate substantially in the
manner hereinabove 'described.
3, The improved forms'of bricks.or-blocks shewn-in and described with reference
respectively to Figs 1 and 2; Fig 3; Fig 4; Fig 5; Fig 6; Fig 7; Figs 11 and 12;
Fig 13; Fig 14; Fig 15; Fig 16; and Figs 20 and 21 of the drawings for the
purposes specified.
