Year: 1853

page_text: LETTERS PATENT to Henry Jackson, of High Street, Poplar, in the
County of Middlesex, for the Invention of "IMPROVEMENTS IN MACHINERY
FOR MOULDING BRICKS AND OTHER ARTICLES OF DRICK EARTH,
PROVISIONAL SPECIFICATION left by the said Henry Jackson at the
Office of the Commissioners of Patents, with his Petition, on the 29th
December 1858.
I, HENRY JACKSON, of High Street, Poplar, in the County of Middlesex, do
hereby declare the nature of the Invention for "IMPROVEMENTS IN MACHINERY
FOR MOULDING BRICKS AND OTHER ARTICLES OP BRICK EARTH" to be as follows:-
This Invention has for its object a peculiar combination of machinery for
moulding bricks and other articles of brick earth. For this purpose the brick
earth is delivered from pug mills or other preparing machinery on to an
incline, and it is then pressed forward by rollers with inclines or blades which
move forward the brick earth on to a series of endless straps of gutta percha
or other suitable material, such straps carrying forward the brick earth in
divided sheets between guides. On the sheets of brick earth arriving over a
table or platform cutting moulds descend, and each mould cuts out a quantity
of brick earth suitable for a brick or other article, depending on the form of
the mould, and by reason of each mould having a piston or plunger thereon
pressed down by a spring or springs tending to force out the plunger or piston.

page_text: the brick earth is pressed in the mould, and when the mould rises the reaction
of the spring or springs forces out the moulded and pressed articles. The
movement of the endless straps carries away the moulded bricks or articles,
and a fresh quantity of brick earth comes under the moulds which again
descend and cut through the brick earth. In order to insure the delivery of
the bricks or articles, a box or vessel with perforated bottom is employed to
dust sand over the brick earth just before it comes to the moulds. The
bricks or articles thus moulded are taken by hand from the several endless
straps.

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Jackson in the Great Seal Patent Office on the 29th
June 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
JACKSON, of High Street, Poplar, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date, the Twenty-ninth day of December, in the year of our
Lord One thousand eight hundred and fifty-three, in the seventeenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Henry Jackson, Her special licence that I, the said Henry Jackson,
my executors, administrators, and assigns, or such others as I, the said Henry
Jackson, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use; exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY FOR
MOULDING BRICKS AND OTHER ARTICLES OF BRICK EARTH," upon the condition
(amongst others) that I, the said Henry Jackson by an instrument in writing
under my hand and seal, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office, within six calendar
months next and immediately after the date of the said Letters Patent,
NOW KNOW YE, that I, the said Henry Jackson, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed;
to be particularly described and ascertained in and by the following statement
thereof (that is to say):-
This Invention has for its object a peculiar combination of machinery for

page_text: moulding bricks and other articles of brick earth. For this purpose the brick
earth is delivered from pug mills or other preparing machinery on to an incline,
and it is then pressed forward by rollers with inclines or blades which move
forward the brick earth on to a series of endless straps of gutta percha or other
suitable material, such straps carrying forward the brick earth in divided sheets
between guides. On the sheets. of brick earth arriving over a table or plat-
form cutting moulds descend, and each mould cuts out a quantity of brick
earth suitable for a brick or other article depending on the form of the mould,
and by reason of each mould having a piston. or plunger therein pressed down
by a spring or springs tending to force out the plunger or piston, the brick
earth is pressed in the mould, and when the mould rises the reaction of the
spring or springs forces out the moulded and pressed articles.
The movement of the endless straps carries away the moulded bricks or
articles, and a fresh quantity of brick earth cones under the moulds, which
again descend and cut through the brick carth. In order to ensure the
delivery of the bricks or articles, a box or vessel with perforated bottom is
employed to dust sand over the brick earth just before it comes to the moulds.
The bricks or articles thus moulded are taken by hand from the several
:
endless straps.
Having thus stated the nature of my Invention, I will proceed to describe
the manuer of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a longitudinal section; Figure 2, a plan; and Figure 3, a
side elevation of a machine constructed according to my Invention.
a, a, is
the framing of the machine; b, is the main shaft or axis which receives motion
by a band over the pulley b' from a steam-engine or other motive power; c, c²,
are cranks fixed on each end of the axis b, which give motion by means of the
connecting rods d, d', to the bell cranked levers e, e', fixed on the axes &², e³,
supported by the side framings of the machine; f, f, are other connecting
rods which connect the bell cranked levers e, e', with the crank levers g, g',
moving freely on the axes h, h', upon which are fixed the pressing rollers
i,, which act at alternate intervals to move forward the brick earth as it
comes from the pug mill or other preparing machinery down the incline k, l,
between the pressing rollers i, j, and i, j, on to the endless straps or bands 7, 1,
of gutta percha or other suitable material to be carried under the cutting
moulds v, v, as hereafter described. The crank levers g, g', give motion alter-
nately to the ratchet wheels n, n', fixed on the axes of the feed rollers i, i¹, by
means of the drivers n², as shewn; and o, o', are toothed wheels fixed on the

page_text: axes i, 2, which take into and give motion to the toothed wheels p, p, fixed on
the axes of the upper feed or pressing rollers j, j. The endless bands or
straps 1,, receive motion by passing partly round the lower pressing rollers,
and are supported at the other end of the machine by passing partly round
the rollers,, the upper parts of the endless bands being supported by the
rollers. The brick earth (and straps 1, P.) as it passes from between the
pressing rollers is conducted along channels formed by the sides and centre
framing of the machine, and is guided between guide rollers q, q, on to tables
or platforms r, r, supported underneath the cutting moulds v, v, the action of
one of which I will now proceed to describe. t, t, are excentrics fixed in opposite
positions on the main shaft or axis b, in order to counter balance or equalize
the action of the two moulds v, 14; the excentric t gives an up and down move-
ment to the frame v* by means of a connecting rod to, the frame * to which
the mould vis affixed, being guided up and down in slots formed in the framing
of the machine; is a piston or plunger working up and down in the mould
2, so as to form the upper side of the mould when at its highest position in the
mould, and against which (and the strap resting on the table which forms the
bottom of the mould) the brick earth is compressed during the descent of
the mould; is the piston rod, which is guided up and down through an
opening formed in the cross bar ; and , v, are spiral springs which act and
are alternately compressed between the cross bar a and the collars &,, fixed
on the piston rod; the spring vo, when compressed by the lifting of the mould,
acting to force the piston outwards so as to discharge the moulded brick or
other article; the compression of the spring v, on the descent of the piston,
acting to raise the piston within the mould. At Figure 4 I have shown a
modification of the apparatus for discharging the brick or other article from
the mould, in which arrangement the discharge of the brick does not depend
upon the springs; u, u, are guides affixed to the mould frame v*, and through
which the piston rod is guided; u is a stop affixed on the piston rod, upon
the upper side of which the levers u, u, are caused to act during the partial
ascent of the frame v*, so as to retain the piston from rising until the brick is
discharged; the levers u, 162, are connected by pin joints to the rods u', and to
the connecting rod t, by which the levers
are brought into action upon the
down, and then release it to be
fixed stop, and caused to retain the piston
lifted by the action of the spring v'. The bricks or other articles when
discharged from the moulds are conducted by the movement of the endless
band on to a frame w; one end of which rests on the surface of the roller
the other end being jointed at w¹ to the balanced levers w; and when the
brick has been received on to the frame w, the attendant places a board or

page_text: pallett upon the brick and tilts the frame w (by means of a handle) upon its
axis w, so as to transfer the brick or other article on to the board or pallet to
be carried away; x, is a box or vessel, perforated at bottom or covered with
wire gauze, containing sand to be dusted over the brick earth before it comes
to the moulds; al, is a connecting rod, which is connected by pin joints to the
sand box a, and to a lever arm ³, fixed on one of the axes e, e³, by which a
rocking motion is given to the sand box .
Having thus described the nature of my said Invention, and the manner of
performing the same, I would have it understood that I make no claim to any
of the mechanical parts separately, nor do I confine myself to the precise details
so long as the peculiar character of the Invention is retained; but what I claim
is, the combination herein described.
In witness whereof, I, the said Henry Jackson, have hereunto set my
hand and seal, this Twenty-ninth day of June, in the year of our Lord
One thousand eight hundred and fifty-four.
Witness,
J. G. TONGUE.
HENRY JACKSON. (L.B.)
