page_text: LETTERS PATENT to Thomas Gater, of West Brompton, in the County of
Middlesex, for the Invention of " IMPROVEMENTS IN THE CONSTRUCTION AND
ARRANGEMENT OF MOULDS TO BE USED IN THE ManufactURE OF BRICKS."
PROVISIONAL SPECIFICATION left by the said Thomas Gater at the Office
of the Commissioners of Patents on the 8th June 1877.

"IMPROVEMENTS
IN THE CONSTRUCTION AND ARRANGEMENT OF MOULDS TO BE USED IN THE MANU-
FACTURE OF BRICKS."
This Invention relates to certain improvements in the construction and arrange-
ment of moulds by means of which bricks can be manufactured and moulded and
also removed from the moulds with greater rapidity and facility than has hitherto
been attainable in the manufacture of bricks by manual labour.
On a horizontal bed plate or table are placed any desired number of strips of
wood or metal, the same being.arranged side by side, and provided at the respective
ends thereof with handles, by means of which they can be readily lifted, removed,
and replaced, as may be desired.
The strips of wood or metal (which form the bottoms of the moulds, as herein-after
mentioned) are respectively a little wider than the width which it is intended the
bricks shall possess, and are of such a length as to correspond with the length of
any given number of bricks. The upper faces of the said strips of wood or metal
are provided with projections for the purpose of forming the requisite hollowed
portions of the bricks.
..
When metal is employed, such projections may be cast with the strips, and when..
wood is used, the same may be attached in any suitable manner.
The strips of wood or metal are held in position by means of pins, or bolts, or any
other contrivance adapted for the purpose.
The sides of the moulds are formed by means of strips of wood or metal, which
are respectively slotted, so as to allow of the same being arranged longitudinally.
and transversely by the slots being brought into coincidence with each other and

together, the points of junction being so arranged as to correspond with the length
and width of the bricks to be manufactured. By these means a series of cells or
moulds, each of which is capable of holding the necessary quantity of clay or other
material for one brick, is thus formed, and upon the same being placed upon the
strips of wood or metal which constitute the bottoms of the moulds the clay or
other material is forced into the cells or moulds, and when sufficiently dried the
strips of wood or metal which compose the sides of the cells or moulds are lifted
and withdrawn (handles being provided for that purpose), when the bottoms of the
cells or moulds can also be lifted, and the bricks removed and deposited as may be
desired.
Instead or forming the cells or moulds by means of the slotted strips of wood or
metal, as hercin-before mentioned, the same may be formed by employing
longitudinal strips of wood or metal, having grooves therein for the reception of
transverse pieces of wood or metal, and which are inserted or slid into the said
grooves, and removed when desired.
The strips of wood or metal upon which the bottoms of the bricks are moulded
may be so arranged as to form one side of the mould, instead of the bottom thereof,
as herein-before described.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Thomas Gater in the Great Seal Patent Office on the 8th December
1877.
THOMAS GATER, of West Brompton, in the County of Middlesex.
"IMPROVEMENTS
IN THE CONSTRUCTION AND ARRANGEMENT OF MOULDS TO BE USED IN THE MANU-
FACTURE OF BRICKS."
My said Invention relates to certain improvements in the construction and
arrangement of moulds by means of which bricks can be manufactured and
moulded, and also removed from the moulds with greater rapidity and facility than
has hiherto been attainable in the manufacture of bricks by inanual labour.
On a horizontal bed plate or table are placed any desired number of strips of
wood or metal, the same being arranged side by side, and provided at the respective
ends thereof with handles, by means of which they can be readily lifted, removed,
and replaced, as may be desired.
These strips of wood or metal (which form the bottoms of the moulds, as herein-
after mentioned) are respectively a little wider than the width which it is intended
the bricks shall possess, and are of such a length as to correspond with the length
of any given number of bricks. The upper faces of the said strips of wood or metal
are provided with projections for the purpose of forming the requisite frogs or
hollowed portions of the bricks.
When metal is employed, such projections may be cast with the strips, and when
wood is used, the same may be attached in any suitable manner.
The strips of wood or metal are held in position by means of pins, or bolts, or any
other contrivance adapted for the purpose.

page_text: The sides of the moulds are formed by means of strips of wood or metal, which
are respectively slotted, so as to allow of the same being arranged longitudinally
and transversely by the slots being brought into coincidence with each other and
passed over the unslotted portions, whereby the strips of wood or metal are held
together, the points of junction being so arranged as to correspond with the length
and width of the bricks to be manufactured. By these means a series of cells or
moulds, each of which is capable of holding the necessary quantity of clay or other
material for one brick, is thus formed, and upon the same being placed upon the
strips of wood or metal which constitute the bottoms of the moulds the clay or
other material is forced into the cells or moulds, and when sufficiently dried the
strips of wood or metal which compose the sides of the cells or moulds are lifted
and withdrawn (handles being provided for that purpose), when the bottoms of the
cells or mioulls can also be lifted, and the bricks removed and deposited as may be
desired.
When it is desired to remove the strips of wood or metal forming the sides
separately, the respective ends of each strip are provided with handles; but in cases
where the strips are fastened together, or when it is desired to remove the whole of
the strips at once, handles are arranged at each corner, or in any other suitable or
convenient manner.
Instead of forming the cells or moulds by means of the slotted strips of wood or
metal, as herein-before mentioned, the same may be formed by employing
longitudinal strips of wood or metal having grooves therein for the reception of
transverse pieces of wood or metal, and which are inserted or slid into the said
grooves, and removed when desired.
The strips of wood or metal upon which the bottoms of the bricks are moulded
may be so arranged as to form the side of the mould, instead of the bottom thereof,
as herein-before described.
Having thus declared and ascertained the nature of my said Invention and the
manner in which the same is to be performed, I would observe in conclusion that
what I consider novel and original, and therefore claim as constituting the Invention
secured to me by the said herein-before in part recited Letters Patent are, the
improvements in the construction and arrangement of moulds to be used in the
manufacture of bricks, substantially as herein-before set forth and described, or any
mere modification thereof.
In witness whereof, I, the said Thomas Gater; have hereunto set my hand and
seal, this Sixth day of December, in the year of our Lord One thousand
eight hundred and seventy-seven.
THO. GATER. (L.S.)
