IMPROVEMENTS IN BRICKMAKING MACHINERY
Year: 1873

page_text: LETTERS PATENT to Jabez Woolley and Thomas Padgett, both of
Hunslet, near Leeds, in the County of York, for the Invention of
"IMPROVEMENTS IN BRICKMAKING MACHINERY."
Sealed the 16th January 1874, and dated the 16th October 1873.
PROVISIONAL SPECIFICATION left by the said Jabez Woolley and
Thomas Padgett at the Office of the Commissioners of Patents,
with their Petition, on the 16th October 1873.
We, JABEZ WOOLLEY and THOMAS PADGETT, both of Hunslet, near
Leeds, in the County of York, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN BRICKMAKING MACHINERY," to be as
follows:-
The object of our Invention is to produce a machine of great
simplicity, and not liable to break down or get out of order, at the same
time capable of turning out a great amount of work and of a good
Quality

page_text: mould is provided a loose plate, which is lifted upward in the mould
by means of a cam, eccentric, or equivalent means, whereby the brick
after being formed is forced out of the mould.
Above the table and in slides between the framework is fitted, so
as to work freely, one or more rammers, which by preference are heated 5
and actuated by a crank, eccentric, or equivalent means; the rammers
pass into the moulds to a suitable extent for the purpose of pressing the
brick. On the samo table is provided a box or measure, into which
the clay is first passed from a hopper of ordinary construction in a
semi-plastic state; by this arrangement the amount of clay can be 1
regulated in accordance with the size of the brick required. Whilst
this box or measure is being filled the brick in the mould is being
pressed. An intermittent reciprocating motion is imparted to the box
or measure by means of a cam.
The brick after being pressed is forced out of the mould by the 1
herein-before mentioned loose plate, then the box or measure is put in
motion, and sliding forward passes over the mould, thereby pushing the
brick off the plate on to the table, whence it is taken by the attendant;
the box or measure at the same time deposits its contents into the
mould ready for another brick.
Motion is imparted to the machine through gearing from some.
suitable motive power.

Over the hopper we provide a revolving siove of a conical or parallel
form, through which the clay passes. All large pieces that will not
pass through the sieve are conducted back again into the grinding pan, a
thus preventing breakage of machinery and producing a brick of a
regular consistency throughout.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by tho said Jabez Woolley and Thomas Padgett in the
Great Seal Patent Office on the 16th April 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, Jabez
WOOLLEY and THOMAS PADGETT, both of Hunslet, ucar Leeds, in the
County of York, send greeting.

bottom of each mould is provided a lifter d, which is forced upwards,

Above the tables 6 and in the slides f-between the framework a is.
fitted, so as to work freely, the rammers g, which may be lieated and
actuated by cranks - through connecting rods . These connecting-
rods may be made adjustable, as shewn in detail at Fig. 4, for the
purpose-of-varying the thickness of the bricks: The packing for
adjusting the length of connecting rod is put in, as shewn at t; Fig.‍4,
by which means the length of the rod is increased or diminished.
The rammers 9 pass to any required extent into the moulds c for the
purpose of pressing the bricks. Underneath the lifter d-we provide:
the safety lovers i, having adjustable balance weights j. These balance 1
weights ; may be placed either above or below the levers i, and at any
required distance from their fulcrums k; by this arrangement any

very fine, there will be no additional strain upon the machine. Tho
safety levers i come in contact with and act upon the lifters d, as shewn:
at l. The lifters & when required may be heated in the same manner.
as the rammers 9. On the tables are provided the boxes or measures-m,
into which the clay is first passed in a semi-plastic state; by this.
arrangement the amount of clay may be regulated in accordance with 2
the size of the brick required. Whilst the boxes or measures m aro
being filled the clay in the mould is being pressed into a brick.
An intermittent reciprocating motion is imparted to the box or
measure by means of a cam n, the required movement being transmitted
thereto by the levers ọ and rods p.
Motion is given to the machine from some suitable motive power
transmitted thereto through driving pulley 9, shaft r, and gearing 8.
