IMPROVEMENTS IN OR APPLICABLE TO BRICK-MAKING MACHINES
Year: 1875

page_text: LETTERS PATENT to Thomas Constantine Fawcett, of Leeds, in the
County of York, Engineer, and Charles Bowman Allen, of the same
Place, Foreman, for the Invention of "IMPROVEMENTS IN OR APPLICABLE
TO BRICK-MAKING MACHINES.'
"
Scaled the 21st August 1875, and dated the 22nd February 1875.
PROVISIONAL SPECIFICATION left by the said Thomas Constantine
Fawcett and Charles Bowman Allen at the Office of the Com.
missioners of Patents, with their Petition, on the 22nd February
1875.
We, THOMAS CONSTANTINE FAWCETT, of Leeds, in the County of York,
Engineer, and CHARLES BOWMAN ALLEN, of the same Place, Foreman,
do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN OR APPLICABLE TO BRICK-MAKING MACHINES," to be as follows:-
This Invention relates to means or apparatus to be employed for
lubricating the faces of the moulds in brick-making machines. For this
purpose we employ a vessel to contain the oil or other lubricant, and

page_text: from this vessel is an outlet communicating with a cylinder large
enough to contain a sufficient quantity of lubricant for lubricating the
face of one die. From this cylinder the oil passes through a pipe
terminating in a "rose-" placed in such manner that the lubricant on
being projected therefrom will fall on to or strike the surface of the die.
The projection of the lubricant is effected by a piston working within
the cylinder, motion being given to the piston by levers and springs so
arranged that the rotation of the mould table shall cause the piston to
be drawn back, and the levers being released the springs acting in a
contrary direction will force the piston upwards sharply and so project
the lubricant. Other means may be adapted for this purpose.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Constantine Fawcett and Charles Bowman
Allen in the Great Seal Patent Office on the 21st August 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
CONSTANTINE FAWCETT, of Leeds, in the County of York, Engineer,
and CHARLES BOWMAN ALLEN, of the same Place, Foreman, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of February, in the
year of our Lord One thousand eight hundred and seventy-five, in
the thirty-eighth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto us, the said Thomas Constantine Fawcett
and Charles Bowman Allen, Her special licence that we, the said Thomas
Constantine Fawcett and Charles Bowman Allen, our executors, admini-
strators, and assigns, or such others as we, the said Thomas Constantine
Fawcett and Charles Bowman Allen, our 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 OR APPLICABLE TO
BRICK-MAKING MACHINES," upon the condition (amongst others) that we,
the said Thomas Constantine Fawcett and Charles Bowman Allen, our

page_text: executors 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
5 Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Thomas Constantine Fawcett
and Charles Bowman Allen, 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
and accompanying Sheet of Drawings (that is to say):-

This Invention relates to means or apparatus to be employed for
lubricating the faces of the moulds in brick-making machines.. For this
purpose we employ a vessel to contain the oil or other lubricant, and
from this vessel is an outlet communicating with a cylinder large
enough to contain a sufficient quantity of lubricant for lubricating the
face of one die. From this cylinder the oil passes through a pipe
terminating in a rose" placed in such manner that the lubricant on
being projected therefrom will fall on to or strike the surface of the die.
The projection of the lubricant is effected by a piston working within
the cylinder, motion being given to the said piston by levers and springs
so arranged that the rotation of the mould table shall cause the piston
to be drawn back, and the levers being released the springs acting in a
contrary direction will force the piston inwards sharply and so project
the lubricant. Other means may be adapted for this purpose.
In order that this Invention may be more fully understood, we herein
give reference to the accompanying Sheet of Drawings illustrative
thereof.
Fig. 1 is front elevation, and Fig. 2, end elevation of such parts of a
brick-making machine as are necessary to illustrate our Invention.
A is the cylinder, and B the die or mould; C is a cistern containing
oil or other lubricant, and this cistern communicates through the pipe D
with a small cylinder E; a piston F is worked to and fro in the
cylinder E by means of the bell-crank lever G, the backward movement

page_text: the said lever is brought sharply back to its former position by the
action of the spiral spring J. On the backward movement of the piston
the orifice of the pipe D is opened and the oil flows into the cylinder,
filling the space vacated by the piston and rising into the pipe K to the
level of the oil in the cistern. The pipe K terminates in a rose or
other spreading device L, and as the piston is forced sharply into the
cylinder on its return stroke the oil is forced through the pipe K and
impinges upon the face of the mould B.
"
"
Various means or modifications of apparatus may be employed for
operating the piston other than those herein described and shewn by the 1
Drawings, but what we claim as of our Invention is the combination
and arrangement of mechanism applied and operated in manner, sub-
stantially as and for the purpose herein shewn and described.
In witness whereof, I, the said Charles Bowman Allen, for and on
behalf of myself and the said Thomas Constantine Fawcett, have 1
hereunto set my hand and seal, this Nineteenth day of August,
in the year of our Lord One thousand eight hundred and seventy-
five.
