OTHER ARTICLES THEREPROM.
"
Sealed the 1st July 1878, and dated the 15th May 1873.
PROVISIONAL SPECIFICATION left by the said Joseph Armytage
Wade and John Cherry at the Office of the Commissioners of
Patents, with their Petition, on the 15th May 1873.
We, JOSEPH ARMYTAGE WADE, of the Borough of Kingston-upon-
Hull, and of Hornsea, in the East Riding of the County of York,
Timber Merchant, Shipowner, and Brick Manufacturer, and JOHN
CHERRY, of Hornsea aforesaid, Brick Yard Manager, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR

page_text: PRESSING CLAY AND OTHER PLASTIC SUBSTANCES IN ORDER TO FORM TILES AND OTHER
ARTICLES THEREFROM," to be as follows:-
Our Invention has referred to improvements on a former Invention,
for which a Patent was granted to us bearing date 12th January, 1871
(No. 74), and consists in making the pallet employed to form the t
undercut flanges on the one side of the tiles to clear itself from the said
flanges by the same power which lifts the lid of the press box, thereby
dispensing with the necessity of removing a loose pallet from the tile
after the pressure has been applied to it.
When worked by hand the lid of the press box and the pallet 1
connected thereto may be lifted as required by means of a lever with a
counterbalancing weight, the attendant working this lever with facility
by acting on a knob fixed at the end of the lever connected with the
pallet, and opposite to that end of the press box lid which carries the
counterbalancing weight, or other means of producing the required 1
motion of the lid. The manual power required for the purpose is only
that which is necessary to slide the pallet clear of the flange of the tile,
and to overcome the effect of the vacuum or partial vacuum under the
lid at the commencement of its rising from the box, and assist the
balance weight to raise the lid, the further raising of the lid being a
effected by the lever acted upon by the counterbalancing weight, or
otherwise acted upon.
The said pallet is connected to the lid by a link and guide connection
acted upon by a lever having its fulcrum in the lid of the box, such lever
having at one end the knob before referred to (when the press is worked
by hand) and at the other end the said link and guide connection of the
pallet.
The press box above referred to is fixed on the top of a press, which
may be mounted on wheels, which press may be worked by a hand lever
in order to give the required pressure to the bottom pallet or moveable :
bottom of the box by means of a pair of excentrics or cams and a
roller. The said hand lever is retained as required by a catch and catch
wheel. And the lid of the press box is secured by a catch at the time
of pressing.
When the lid of the press box is lifted as required by mechanical
power instead of by hand, modifications will be made in some of the
parts above referred to in order to effect the required movement of the

page_text: upper pallet and of the lid of the box, and to impart the required
pressure to the bottom pallet or moveable bottom of the box without the
oxcentrics or cams and roller above referred to.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Joseph Armytage Wade and John Cherry in the
Great Seal Patent Office on the 13th November 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPH
ARMYTAGE WADE, of Kingston-upon-Hull, and of Hornsea, in the East
Riding of the County of York, Timber Merchant, Shipowner, and
Brick Manufacturer, and JOHN CHERRY, of Hornsea aforesaid, Brick
Yard Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of May, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-.
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Joseph Armytage Wade and John Cherry,
Her special licence that we, the said Joseph Armytage Wade and John
Cherry, our executors, administrators, and assigns, or such others as we,
the said Joseph Armytage Wade and John Cherry, our executors, admini-
strators and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein ex-.
pressed, 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 APPARATUS
FOR PRESSING CLAY AND OTHER PLASTIC SUBSTANCES IN ORDER TO FORM TILES AND
OTHER ARTICLES THEREFROM," upon the condition (amongst others) that we,
the said Joseph Armytage Wade and John Cherry, our exccutors or
administrators, by an instrument in writing under our, 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 calender months next, and immediately after the date
of the said Letters Patent.

page_text: NOW KNOW YE, that we, the said Joseph Armytage Wade and John
Cherry, do hereby declare the nature of our 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 Drawings hereunto annexed, and to the letters and figures marked
thereon (that is to say) :-
Our Invention of "Improvements in Apparatus for Pressing Clay
and other Plastic Substances in order to Form Tiles and other Articles
therefrom," has reference to improvements in press boxes and presses for
forming tiles and other articles with undercut flanges, and consists in
making the pallet employed to form the undercut flanges on the one
side of the tiles or other articles to clear itself from the said flanges by
the same power which lifts the lid of the press box, thereby dispensing
with the necessity of removing a loose pallet from the tile or other
article after the pressure has been applied to it.
When worked by hand the lid of the press box and the pallet
connected thereto may be lifted as required by means of a lever and a
counterbalancing weight, the attendant working this lever with facility
by acting on a knob fixed at the end of the lover connected with the
pallet and opposite to that end of the press box lid which carries the
counterbalancing weight or other means of producing the required
motion of the lid. The manual power required for the purpose is only
that which is necessary to slide the pallet clear of the flange of the tile,
and to overcome the effect of the vacuum or partial vacuum under the
lid at the commencement of its rising from the box, and assist the
balance weight to raise the lid, the further raising of the lid being
effected by means of the counterbalancing weight, or it might be
otherwise effected.
The said pallet is connected to the lid by a link and guide connection
acted upon by a lever having its fulcrum in the lid of the box, such
lever having at one end the knob before referred to (when the press is
worked by hand), and at the other end the said link and guide connection
of the pallet.
The press box above referred to is fixed on the top of a press which
may be mounted on wheels, which press may be worked by a hand lever
in order to give the required pressure to the bottom pallet or moveable

page_text: in the lid at J) the link K and guide L, which is fixed to the pallet H.
By means of this connection between the lid G and the upper pallet H,
this pallet is slidden the required distance to remove it from the pressed
tile so as to clear the undercut flanges of the same by acting on the end
of the lever I furnished with a knob M for the purpose. This position 5
of the pallet H is shewn in Fig. 4, the lid also being shewn as raised by
the action of the counterbalancing weight N and lever O, and carrying
with it the pallet H away from the pressed tile.
The lever I and other parts forming the connection between the lid G
and the pallet H are shewn detached at Fig. 6.
1
At Fig. 7 is represented in elevation the press on which the press box
above described is fixed; P is a catch or rest for the hand lever by which
the excentric shaft E is worked; Q is the hand lever; R is a catch wheel
on the shaft E, which is held as required by the catch; S is a catch or
stop to hold fast the lid of the press box at the time of applying the 1
pressure to the tile or other article within the box.
The foregoing description relates to the working of the press and
lifting of the lid of the press box by hand. But these operations and
the working of the press may also be performed by the aid of mechanical
power, in which case the arrangement of the counterbalancing weight 2
for lifting the lid and the excentrics for working the moveable bottom of
the press box or bottom pallet might be dispensed with. The required
pressure might also be applied from above instead of from below the
press box, and the arrangement for moving the top pallet so as to make
it slide back from the undercut flange of the pressed tile or other article 2
might be made self-acting.
Having thus described the nature of the said Invention, and in what
manner the same is to be performed, we hereby declare that what we
claim as of our Invention is.-

page_text: And Secondly. The application of the catch and catch wheel to the
tile
press, as herein-before described.
In witness whereof, we, the said Joseph Armytage Wade and John
Cherry, have hereunto set our hands and seals, the Sixth day
of November, in the year of our Lord One thousand eight hundred
and seventy-three.
