Year: 1871

page_text: LETTERS PATENT to Mark Richardson, of Leeds, in the County of
York, for the Invention of "IMPROVEMENTS. IF MACHINERY OR APPARATUS
FOR PRESSING BRICKS, TILES, OR OTHER PLASTIC FORMS."
Sealed the 9th February 1872, and dated the 16th August 1871.
PROVISIONAL SPECIFICATION left by the said Mark Richardson
.
at the Office of the Commissioners of Patents, with his Petition,
on the 16th August 1871.
I, MARK RICHARDSON, of Leeds, in the County of York, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MACHINERY
OB APPARATUS FOR PRESSING BRICKS, TILES, OR OTHER PLASTIC FORMS,” to be as
follows:-
ני
On suitable framework of cast iron I mount a sliding table. On the
framework I also mount two pillars, on the top of which a cross piece is..
fixed, in which a bar is fitted so as to slide freely, and having the.
required mould attached to it. A reciprocating motion is given to the

page_text: "
bar carrying the mould to a cross head to which it is attached, being
transmitted thereto by connecting rods coupled to two cranks or discs,
the latter preferred, by means of suitable crank pins; on one of theso
discs is formed a cam arranged or constructed in such a manner as to
give an intermittant reciprocating motion to the sliding table by means
of a bell crank lever connected thereto by a connecting rod. On the
sliding table is fitted a plate to receive the plastic form previous to its
being pressed into the mould. The form being placed on the plate by
the attendant it is then carried by the sliding table directly under the
mould into which it is pressed by the mould itself being forced down.
Within the mould is provided a loose plate attached to which are two
adjustable screws. Theso screws are so arranged as to come in contact
with the cross piece as the mould is carried upwards, by which means the
loose plate forces the pressed form out of the mould on to the plate on
the sliding table. The mould being raised clear the form is taken off by
the attendant, and the table worked by the aforesaid cam lever and
connecting rod immediately afterwards travels forward a suitable
distance, and then pauses a sufficient time to allow another unpressed
form to be deposited on it, when it again returns, and the before
described pressing operation is repeated.
Endless sheets of ordinary construction may, if desired, be employed
fox the
of conducting the frums to and form the machine
SPECIFICATION in pursuance of the conditions of the Letters Patent, a
filed by the said Mark Richardson in the Great Seal Patent Office
on the 14th February 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARK
RICHARDSON, of Leeds, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of August, in the year
of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Mark Richardson, Her special licence
that I, the said Mark Richardson, my executors, administrators, and a

page_text: .
assigns, or such others-as I, the said-Mark-Richardson, 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 OR APPARATUS FOR PRESSING BRICKS, TILES, OR OTHER PLASTIC
FORMS," upon the condition (amongst others) that I, the said Mark
Richardson, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, 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 Mark Richardson, do hereby declaro
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying Drawings,
and to the letters of reference marked thereon, that is to say :—
On suitable framework of cast iron I mount a sliding table. On the
framework I also mount two pillars, on the top of which a cross piece is
fixed, in which a bar is fitted so as to slide freely, and having the
required mould attached to it. A reciprocating motion is given to the
bar carrying the mould through a cross head to which it is attached,
being transmitted thereto by connecting rods coupled to two cranks or
discs, the latter preferred, by means of suitable crank pins; on one of
these discs is formed a cam, arranged or constructed in such a manner as
to give an intermittant reciprocating motion to the sliding table by
means of a bell crank lever connected thereto by a connecting rod. On
› the sliding table is fitted a plate to receive the plastic form previous to
its being pressed into the mould. The form being placed on the plate
by the attendant it is then carried by the sliding table directly under
the mould into which it is pressed by the mould itself being forced
down. Within the mould is provided a loose plate, attached to which
; are two adjustable screws. These screws are so arranged as to come in
contact with the crosspiece as the mould is carried upwards, by, which
means the loose plate forces the pressed form out of the mould on to the
plate on the sliding table. The mould being raised clear the form is taken

page_text: and connecting rod immediately afterwards travels forward a suitable
distance, and then pauses a sufficient time to allow another unpressed
form to be deposited on it, when it again returns, and the before
described pressing operation is repeated.
Endless sheets of ordinary construction may, if desired, be employed
for the purpose of conducting the forms to and from the machine.
. Motion is given to the machine through gearing from some suitable
motive power.
Fig. 1 is a front elevation, and Fig. 2 a side elevation of machinery
or apparatus constructed according to my Invention.
A is the framework on which I fit the sliding table B. On the frame-
work A I mount two pillars O, on the top of which a cross piece ´D is
placed. The cross piece D and pillars O are secured to the framework
A by the bolts E, as shewn. A bar F is fitted into the cross piece D so
as to slide freely, having the required mould G fastened thereto by the
bolts H. The required reciprocating motion is given to the bar F
through the cross head -I, coupled as shewn at J; the motion being
transmitted by the connecting rods K attached thereto at L. The
connecting rods K are coupled to the discs M. by means of the crank
pins N. To one of the discs M is bolted the grooved cam O, which is
arranged or constructed in such a manner as to give an intermittant
reciprocating motion to the sliding table B. This motion is transmitted
from the cam O to the table B through the lever R, shaft S, and lever P,
which is connected or coupled to the table B by the connecting links Q
as shewn. A runner T. is fitted on the pin U on the lever R, so as to
work freely in the grooved cam O, thereby imparting motion to the lever
R. On the sliding table B is mounted the carrier V, on which is fitted
the plate W. On the plate W the plastic form is placed previous to its
being pressed into the mould G. The form being placed on the plate W
by the attendant it is carried by the sliding table directly under the
mould G, into which it is pressed by the mould G being forced down
upon it. Within the mould G is provided the loose plate X, attached to
which are the two regulating screws Y; on which are provided the check
nuts Z. These are so placed or adjusted on the screws as to prevent the
plate X from falling out, also to come in contact with the cross piece D
as the mould rises. By this means the plastic form is forced out on to a
1
:

page_text: receiver V, which may be made of wood-of any suitable width, and
placed on the sliding table B, the table B having moved sufficiently
forward to bring the receiver V₁ under the mould G. When in this
position another unpressed form is put on to the receiving plate W,
sufficient time being allowed by the cam O. This being done the table
B again returns, and the before described pressing operation is repeated,
and the pressed form taken off the receiver V¹.
Endless sheets of ordinary construction may, if desired, be employed
for the purpose of conveying the forms to and from the machine.
Motion is given to the machine from the driving pulleys on shaft 1
through pinion 2. and spur wheel 3, actuated by some suitable motive
power. To assist in driving the machine I employ a fly wheel 4 on the
shaft 1.
Having now described the nature of my said Invention, and the
manner in which the same is to be performed, it is to be understood that
I do not limit myself to the exact details and configuration of parts I
have described and shewn, as the same may be varied or modified
without in any way departing from my Invention, but what I do claim
and desire to be secured to me by Letters Patent is, the construction,
combination, and arrangement of machinery, herein fully described and
shewn, whereby bricks, tiles, or other plastic forms may be pressed.
In witness whereof, I, the said Mark Richardson, have hereunto
set my hand and seal, this Thirteenth day of February, in the
year of our Lord One thousand eight hundred and seventy-two.
