Year: 1875

page_text: LETTERS PATENT to Thomas Titley, of Leeds, in the County of York,
for the Invention of "IMPROVEMENTS IN MACHINERY FOR PRESSING
BRICKS OR OTHER PLASTIC FORMS."
Sealed the 21st September 1875, and dated the 27th July 1875.
PROVISIONAL SPECIFICATION left by the said Thomas Titley at the
Office of the Commissioners of Patents, with his Petition, on the
27th July 1875.
I, THOMAS TITLEY, of Leeds, in the County of York, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MACHINERY
FOR PRESSING BRICKS OR OTHER PLASTIC FORMS," to be as follows
-
My improvements have reference to screw presses employed for
pressing bricks or other plastic forms whereby the work may be done
much quicker than by machines of ordinary construction.
The framework is similar to that of the ordinary screw press, and I
also employ the ordinary screw but in combination therewith, and cut
on the same shaft is another screw of a different "hand.” This second

down to its work by turning the ordinary screw, but simultaneously the

By this means the presser plate is brought down and the form pressed
in at least half the time required by machines of ordinary construction
without any perceptible loss of power.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Titley in the Great Seal Patent Office
on the 27th January 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
TITLEY, of Leeds, in the County of York, send greeting.
WHEREAS Ücr most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of July, in the year
of our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Thomas Titley, Her special licence
that I, the said Thomas Titley, my exccutors, administrators, and
assigns, or such others as I, the said Thomas Titley, 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 Ircland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
MACHINERY FOR PRESSING BRICKS OR OTHER PLASTIC FORMS," upon the condition
(amongst others) that I, the said Thomas Titley, 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

page_text: Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent
NOW KNOW YE, that I, the said Thomas Titley, do hereby
declare 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 accom-
panying Drawings, and to the letters of reference marked thereon, that
is to say:-
My improvements have reference to screw presses employed for
pressing bricks or other plastic forms whereby the work may be done
much quicker than by machines of ordinary construction.
The framework is similar to that of the ordinary screw press, and I
also employ the ordinary screw but in combination therewith, and cut
on the same shaft is another screw of a different "hand." This second
screw works in a nut formed by preference in the head or boss of the
presser plate. By this arrangement not only is the presser plate moved
down to its work by turning the ordinary screw, but simultaneously the
other screw causes the presser plate to be worked down on to the form.
By this means the presser plate is brought down and the form pressed
in at least half the time required by machines of ordinary construction
without any perceptible loss of power.
The lifting plate in the mould in the table is so connected with tho
presser plate that it forces the form out of the mould simultaneously
with the lifting of the presser plate.
And in order that my Invention may be more completely understood
reference is given to the accompanying three Sheets of Drawings, and to
the letters and marks thereon.

page_text: The framework a is similar to that of the ordinary screw press, and I
also employ the ordinary screw, as shewn at b, but in combination
therewith and cut on the same shaft is another screw c of a different
"hand; " this second screw e works in a nut d, formed by preference
in the head or boss e of the presser plate ƒ By this arrangement not
only is the presser plate f moved down to its work by turning the
ordinary screw 6 but simultaneously the other screw c working in the
nut & in the boss e of the presser plate causes the presser plate f to
work down on to the form. By this means the presser plate ƒ may be
brought down in at least half the time required by machines of ordinary
construction without any perceptible loss of power
Figure 2, Sheet 2, shews an arrangement whereby I utilize the boss of
the-presser plate fas a nut, as shewn at g, and dispense with the nut
shown in Figure 1.
66
Figure 4 shews another modification of my Invention, in which is an
external screw, 2 an internal screw; 7 is a nut secured to the upper
part of the framework a by means of the bolts k, and the interior of
the screw forms a nut for the screw ; the end of the screw i
being produced to the required length is attached in the ordinary
manner to the piesser plate. The screws hand are made of different
hands," consequently on the external screw h being caused to revolve
by means of the swing lever or other convenicut arrangement may be
caused to traverse downwards or upwards in the nut 1, causing thereby
the inner screw working in the internal nut formed in the screw h
simultaneously to be moved downwards or upwards, carrying with it
the presser plate. By this means the presser plate fis brought down
or up in a similar manner to that described for the presser plate f
Sheets 1 and 2.
The lifting plate m in the mould n on the table o is connected with
the presser plate as follows-Above the presser plate f is provided a
beam p, to which is attached by the rods q another beam or plate r
underneath the table o; the plate or beam is attached to the lifting
plates m by means of the rods &
By this arrangement the lifting
plate m forces the forms out of the mould n simultaneously with the
lifting of the presser plate f. In some cases only one rod 8' is required;
in this case I release and reverse the plate or beam 7 and attach the
rods' to the lifting plate m, this is required in some cases to suit the
shape of the mould.

page_text: Figure 5 shows an arrangement of lifting plate which is constructed as
follows t is a framework within the mould n, to which is attached the
rods s in the manner herein-before described In this case that part of
the lifting plate which forms the hollow is made separate from the outer
part or framework t and fixed to the table o, as shewn at u, whereby on
the form being lifted out of the mould it is relieved from the projecting
part v, so that when clear of the top of the mould the brick or other
form can be more readily taken away and with less injury thereto
various parts not herein explained are of ordinary construction.
The
Having now described the nature of my said Invention, and shewn by
Drawings how the same may be carried into practice, I would have it
understood that I do not limit myself to the exact details or configuration
of the parts I have explained and shewn, as the same may be vaned 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,—
-
Fust. The arrangement, construction, and application of right and
left hand screws and parts connected therewith, whereby the presser
plate is worked down on to the form for the purpose of pressing the
same, with mere modifications, substantially as herein set forth.
Second. The combination of the herein-before mentioned screw
arrangement with the other parts forming the machine, substantially as
and for purposes herein set forth.
In witness whereof, I, the said Thomas Titley, have hereunto set
my hand and seal, this Twenty-fifth day of January, in the year
of our Lord One thousand eight hundred and seventy-six
