IMPROVEMENTS IN THE PRESSING OF BRICKS
Year: 1874

page_text: LETTERS PATENT to John Gill, of Hunslet, near Leeds, in the County
of York, for the Invention of "IMPROVEMENTS IN THE PRESSING OF
BRICKS."
Sealed the 25th September 1874, and dated the 9th April 1874.
PROVISIONAL SPECIFICATION left by the said John Gill at the Office
of the Commissioners of Patents, with his Petition, on the 9th
April 1874.
I, JOHN GILL, of Hunslet, near Leeds, in the County of York, do
hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE PRESSING OF BRICKS," to be as follows:-
My Invention relates to an improved brick-pressing machine, which
brings the bricks to the die to be pressed, and removes and them
passes
on to the kiln after pressing in a self-acting manner and without any
attendance.
The machine consists of a presser worked up and down in slides by an
Beneath the
excentric upon a shaft at the upper part of the machine.
presser is a die, in which works a lifter to raise the brick out of the die

page_text: after being pressed, also operated by eccentrics on the same shaft. The
bricks, which are fed to the pressing machine by a creeper from the
brickmaking machine, or deposited on the creeper by hand, are brought
under the presser by a pusher attached to oscillating arms worked by an
excentric also on the above mentioned shaft, by which the pusher is
moved backwards and forwards. In moving backwards the pusher is
also raised by arms, each working on a stud and oscillated by a cam on
the shaft in order to lift the pusher over the next brick advancing on
the creeper, behind which it drops to push it forward under the presser ;
this brick at same time pushing the one that has been pressed on to
another creeper in front. The brick to be pressed is received on the
lifting plate in the die, which immediately drops the full depth of the
brick, and the latter is then pressed by the descent of the plunger, after
which the lifter is raised by its excentrics to remove the brick, and drops
again on receiving a fresh brick to be pressed. For this purpose the
lifter is not connected to the eccentric rods, but has studs working in a
right angled slot therein. In lifting the bricks out of the mould the
studs are kept in the horizontal part of the slots by the pressure of a
weighted lever against the eccentric rods until a projection on the latter
comes in contact with a stud, whereupon the weighted lever is forced
back and the lifter allowed to drop into the vertical part of the slot.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Gill in the Great Seal Patent Office on the
9th October 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN GILL,
of Hunslet, near Leeds, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of April, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Gill, Her special license that
I, the said John Gill, my executors, administrators, and assigns, or such
others as I, the said John Gill, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at
all times thereaftor during the term therein expressed, should and

page_text: 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 THE PRESSING. -OF-BRICKS,"
upon the condition (amongst others) that I, the said John Gill, my.
executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, should particularly describo
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 John Gill, 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, reference being had to the accompanying
Sheet of Drawings and to the letters and figures marked thereon (that
is to say):-
My Invention relates to pressing bricks, and consists of an improved
arrangement or combination of machinery or apparatus which when
placed in a suitable position with respect to a brickmaking machine will
bring the bricks to the dic to be pressed, remove them, and pass them
on to a kiln in an entirely self-acting manner without any attendance.
whatever. Or if required to press semi-dry bricks the same can be fed
by hand without risk of accident, inasmuch as by the arrangement of
creeper sheet hereafter described the attendent can be at any safe and
convenient distance from the machine.
The entire machine is characterized by its simplicity of construction,
being compact and self-contained or composed mainly of two castings
which need no foundation, and its adaptability as a self-acting and self-
feeding machine for the purpose above mentioned.
In order that the Invention may be more readily understood I have
described it with reference to the accompanying Drawing, in which
Figure 1 shows a front elevation of the brick-pressing machine with the
devices for feeding and removing the bricks; Figure 2 is a side elevation"
(the die being shown in section); and Figure 3 is a rear elevation of the
same.
The pressing machine comprises a presser A. attached to a cross-head B

page_text: the pusher to have deposited a brick under the presser, where the pressed
brick is shown in the Drawing, the cam will then rock the lever U, so
raising the pusher lever T and pusher S, which are then moved back-
wards over the next brick by the action of spring V, whereupon the cam
releases lever U, and the pusher falls, as shown. Behind the next brick,
which is moved forward in turn the creeper R receives intermittent
motion, as before mentioned, and is coupled with a brickmaking machine,
by which the bricks are deposited on said creeper to be pressed, as above
described. Each brick as it is pressed is pushed away from the die by
the next brick, and is received on a second endless travelling sheet Y,
having continuous motion, by which the pressed bricks are conveyed to
the drying kiln.
In feeding the machine by hand the creeper R would be marked with
transverse lines to indicate the exact positions in which the bricks are to
be deposited by the attendant.
Having described the nature of the Invention, and the manner of
performing the same, I declare that what I claim as my Invention to be
protected by the herein-before in part recited Letters Patent is,-
1st. The combination with a brick-pressing machine constructed as
described of a pusher arranged and operating substantially as shown and
described for the purpose specified.
The combination with the subject of the first claim of a creeper R, to
which intermittent motion is imparted, as described, to receive the bricks
from a brickmaking machine or from the hand of an attendant, as
described, and a second creeper Y to convey the pressed bricks away,
substantially as described.
In witness whereof, I, the said John Gill, have hereunto set my
hand and seal, this Seventh day of October, in the year of our
Lord One thousand eight hundred and seventy-four.
