PROVISIONAL SPECIFICATION.
Improvements in the Construction of Walls, Partitions and other
Structures and in the Form of Bricks or Tiles for the same and in
the Manner of Setting such and other Bricks or Tiles immediately
after Moulding in Hacks for Drying.
JAMES SHEPPARD, Trayshill, Hornsey Lane, London, N., Surveyor, FREDERICK
DASHWOOD, Lindisfarne, Hersham Road, Walton-on-Thames, Clerk of Works, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the form of bricks or tiles to be used
in the construction of walls partitions and other structure the object being to
effect further improvements in the form of, and the mode of building with, the
bricks or tiles described in the Specification of Letters Patent granted to us
Numbered 16654 and dated 1st Sep. 1894, and to reduce the cost. of their
production and use.
The improvement in the form of, and mode of building with, our bricks or tiles
consists in moulding channels on their sides as well as on their ends when they
are to be used in structures having a thickness equal to that of two or more of the
bricks or tiles, the divisions between all such channels being slightly increased in
thickness from their roots to their outer edges so as to secure a dovetailed outline
on plan. When building with our bricks or tiles the usual lime or cement mortar
is applied in the following manner, a layer of mortar is placed on the bed and ends
of the brick or tile and also on the channels on their side when used in structures
exceeding one brick or tile in thickness these layers of mortar are firmly pressed
into position as the bricks or tiles are built together forming dowels and keys of
mortar in all beds and joints respectively.
The concrete filling described in the specification before referred to may be
altogether omitted or used only for the vertical spaces between and below all joints
at the ends of the bricks or tiles and the horizontal channels also described in the
above specification may be omitted if desired.
The improvement in setting our and other bricks or tiles in hacks for drying
immediately after they are moulded consists in using pallets formed with latticed
or pierced corrugated work, of wood metal or other, suitable material so arranged
as to allow free circulation of air which pallets are placed and left between the
bricks or tiles in the hacks all being firmly stacked together to prevent twisting
while drying, the pallets are made slightly deeper than the bricks or tiles and
strips of wood pierced corrugated sheets of metal or other material are placed or
fixed on the upper edges of the pallets so that the whole weight of the different
courses in the hacks is carried by the pallets each brick or tile being firmly held
in a separate cell free from vertical pressure.
Suitable blocks are provided for each end of the hacks to resist thrust from the
closely stacked bricks or tiles and pallets.

page_text: This mode of stacking in hacks to dry is applicable for all kinds of bricks or
tiles that may be liable to twist or warp when drying.

Improvements in the Construction of Walls, Partitions, and other
Structures and in the Form of Bricks or Tiles for the same, and in
the Manner of Setting such and other Bricks or Tiles immediately
after Moulding in Hacks for Drying.
JAMES SHEPPARD, Trayshill, Hornsey Lane, London, N., Surveyor, FREDERICK
DASHWOOD, Lindisfarne, Hersham Road, Walton-on-Thames, Clerk of Works, 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:
This invention relates to improvements in the form of bricks or tiles to be used
in the construction of walls partitions and other structures the object being to
effect further improvements in the form of and the mode of building with the bricks
or tiles described in the Specification of Letters Patent granted to us Numbered
16654 dated 1st September 1894 and to reduce the cost of their manufacture and use.
The improvement in the form of and mode of building with the bricks or tiles
consists in moulding channels on their sides as well as on their ends when they are
to be used in structures having a thickness equal to that of two or more of the
bricks or tiles the divisions between all such channels being slightly increased from
their roots to their outer edges so as to secure a dovetailed outline on plan.
The hollow spaces through the bricks or tiles with the channels on their ends and
sides are varied to suit the different structures for which the bricks or tiles may be
intended. The form and area of these hollow spaces and channels being pro-
portioned so as to secure, when built together, a strength, at the dowelled beds and
keyed joints, equal to that of other parts of the structure.
་
These
When building with these bricks or tiles the usual lime or cement mortar is
applied in the following manner, a layer of mortar is placed on the horizontal joint
or bed of the bricks or tiles and also on the channels on their ends and on their
sides, when used in structures exceeding one brick or tile in thickness.
layers of mortar are firmly pressed into position as the bricks or tiles are built
together so as to form dowels and keys of mortar in all beds and joints respectively.
The concrete filling described in the specification before referred to is altogether
omitted or used only for the vertical joints at the ends and sides of the bricks or
tiles in place of mortar, and the horizontal channels also described in the above
specification may be omitted if desired.
The improvement in setting these and similar bricks or tiles in hacks for drying
immediately after they are moulded consists in using corrugated and pierced
pallets, formed in any suitable material arranged so as to allow free circulation of
air, these pallets are placed between the bricks or tiles horizontally or vertically
and remain in such position until the bricks or tiles are dry and hard, the whole
hack being firmly stacked together to prevent the bricks or tiles warping or twisting
during drying.
Description of diagrams illustrating the improved bricks or tiles referred to in
the foregoing specification.

two or more of the bricks or tiles.
Fig. 3. Elevation shewing the bricks or tiles built in position to form partitions
indicating the mortar dowelled beds and mortar keyed joints.
Fig. 4. Corrugated and pierced pallet for use between the bricks or tiles when
stacked in hacks to dry.
Corresponding portions in the different figures are indicated by the same letters
as follows.
a hollow vertical spaces through the bricks or tiles.
a dowels of mortar in the heds of the bricks or tiles.
b dovetailed vertical channels on the internal faces of the bricks or tiles.
b keys of mortar to the joints of the bricks or tiles.
c shallow channels to form key for plastering.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed we declare that what we
claim is:-
1. In the construction of thin partitions and the like, the combination of bricks
or tiles formed with hollow spaces and channels in which mortar used when build-
ing with the bricks or tiles forms dowels and keys to all beds and joints respectively
for the purpose specified and substantially as described.
2. In the construction of walls and the like the combination of bricks or tiles
formed with hollow spaces and with channels on all internal faces in which mortar
or concrete grouting used when building with the bricks or tiles forms dowels and
keys to all beds and joints respectively for the purpose specified and substantially as
described.
3. The use of corrugated and pierced pallets between bricks or tiles in drying
hacks for the purpose specified and substantially as described.
