Year: 1874

page_text: LETTERS PATENT to Samuel Arnold Luke, of St. John's, Deptford,
in the County of Kent, for the Invention of "IMPROVEMENTS IN
ÅPPARATUS FOR MOULDING AND COMPRESSING SMALL COAL AND OTHER
SUBSTANCES."
Sealed the 26th February 1875, and dated the 2nd September 1874.
PROVISIONAL SPECIFICATION left by the said Samuel Arnold Luke
at the Office of the Commissioners of Patents, with his Petition,
on the 2nd September 1874.
I, SAMUEL ARNOLD LUKE, of St. John's, Deptford, in the County of
5 Kent, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN APPARATUS FOR MOULDING AND COMPRESSING SMALL COAL AND OTHER
SUBSTANCES," to be as follows:-
This Invention relates to certain improvements in the construction of
apparatus and machinery for mixing small coal and other substances,
and moulding and compressing the same into blocks for fuel and other
purposes, and is based upon that class of machinery for which Letters

page_text: Patent were granted to William Edward Newton, as a communication
from Messieurs Couillard and Mageline, bearing date the 24th day of
May 1860, No. 1289, and for which Letters Patent were also granted to
me, bearing date the 15th day of May 1873, No. 1771.
The improved apparatus which forms the subject, of the present In-
vention consists of a bed plate, in the lower part of which is placed a
horizontal shaft, the latter being so arranged as to traverse nearly the
entire length of the bed plate. A vertical shaft is geared by means of
a pair of bevil wheels to the before-mentioned horizontal shaft, such
bevil wheels being of such a size as to allow sufficient space for the
horizontal shaft to pass below the step of the vertical shaft. At the
upper part of the apparatus is placed a feeding pan, through which the
upper portion of the vertical shaft, which is provided with blades or
stirrers, passes. A cam is fixed upon the vertical shaft below the
feeding pan. A revolving table containing moulds, by preference ten in
number, is so arranged as to pass under a portion of the filling pan.
The said table has formed on its outer edge or periphery teeth corre-
sponding in number to that of the mould. The teeth are respectively
of such a depth that the cam on the vertical shaft will move the table
the proper proportion of the circumference thereof, and passing on leave
the table at rest for as great a portion of the revolution of the vertical
shaft as may be required. The moulds having been filled with the
substances under treatment from the filling pan by the operation of the
blades or stirrers pass under a pressing plate, beneath which the said
substances are compressed, such compression being effected by means
of a piston working within a steam cylinder, either below the com-
pressing stamp, as described in the Specification of my said previous
Invention, or as in that of the said William Edward Newton.'
If the steam cylinder be situated as described in the Specification of
my said previous Invention the valve is moved by a crank on the end
of the before-mentioned horizontal shaft. Upon the horizontal shaft is
placed a cam in a line with the centre of the table. A lever provided
for that purpose is so arranged as to push the blocks which have been
compressed out of the moulds, and a small steam cylinder is also so
arranged that the piston rod thereof pushes the blocks off the table, as
described in the Specification of my said previous Invention; but instead
of a balance weight being employed to draw back the piston, as therein
mentioned, a pipe is placed at the front end of the small cylinder and led

page_text: into the valve chest of the large steam cylinder of the machine, and so
arranged that when the valve has moved and exhausted the steam from
the large cylinder and from behind the piston of the small cylinder the
steam will be admitted to the front of the small piston and will push
it back clear of the moulds, also exhausting the steam from the front
end of the piston and allowing it to be moved in the direction required
to remove the blocks.
The apparatus herein-before described may be supplied with the
substance or substances desired to be treated either by a horizontal
mixer or by a pug mill, as may be desired; such necessary gearing being
employed in the latter case, as will be well understood.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Arnold Luke in the Great Seal Patent
Office on the 2nd March 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
ARNOLD LUKE, of St. John's, Deptford, in the County of Kent, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of September, in the year
of our Lord One thousand cight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Samuel Arnold Luke, Her
special licence that I, the said Samuel Arnold Luke, my executors,
administrators, and assigns, or such others as I, the said Samuel
Arnold Luke, 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 APPARATUS FOR MOULDING AND COMPRESSING
SMALL COAL AND OTHER SUBSTANCES," upon the condition (amongst others)
that I, the said Samuel Arnold Luke, 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

page_text: 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 Samuel Arnold Luke, 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 annexed
Drawings, and to the figures and letters marked thereon, that is to
say:―
My said Invention relates to certain improvements in the construction
of apparatus and machinery for mixing small coal and other substances,
and moulding and compressing the same into blocks for fuel and other
purposes, and is based upon that class of machinery for which Letters
Patent, bearing date the 24th day of May 1860, No. 1289, were granted
to William Edward Newton, as a communication from Messrs. Couillard
and Mageline, and for which Letters Patent were also granted to me
bearing date the 15th day of May 1873, No. 1771.
In the improved apparatus which forms the subject of my said
present Invention a bed plate is provided, in the lower part of which
is placed a horizontal shaft, the latter being so arranged as to traverse
nearly the entire length of the bed plate. A vertical shaft is geared by
means of a pair of bevil wheels to the before-mentioned horizontal shaft,
such bevil wheels being of such a size as to allow sufficient space for
the horizontal shaft to pass below the step of the vertical shaft. At
the upper part of the apparatus is placed a feeding pan, through which
the upper portion of the vertical shaft, which is provided with blades or
stirrers, passes. A cam is fixed upon the vertical shaft below the
feeding pan. A revolving table containing moulds, by preference ten
in number, is so arranged as to pass under a portion of the filling pan.
The said table has formed on its outer edge or periphery teeth, which
correspond in number to that of the moulds. The teeth are respectively
of such a depth that the cam on the vertical shaft will move the table
the proper proportion of the circumference thereof, and passing on will
leave the table at rest for as great a portion of the revolution of the
vertical shaft as may be required. The moulds having been filled with
the substance or substances under treatment from the filling pan by the

page_text: operation of the blades or stirrers pass under a pressing plate, beneath
which the said substance or substances is or are compressed; such
compression being effected by means of a piston working within a
steam cylinder, which is placed either below the compressing stamp, as
described in the Specification of my said previous Invention, or as
described in the Specification filed by the said William Edward Newton
in respect of the Invention of the said Messieurs Couillard and Mageline.
If the steam cylinder be situated as described in the Specification of
my said previous Invention the valve will be preferably moved by a
crank, excentric, or cam, formed or fixed on the end of the before-
mentioned horizontal shaft. Upon the horizontal shaft is placed a cam
in a line with the centre of the table. A lever provided for that purpose
is so arranged as to push the blocks which have been compressed out
of the moulds. And a small steam cylinder is also so arranged that the
piston rod working therein pushes the blocks off the table, as described
in the Specification of my said previous Invention, but instead of a
balance weight being employed to draw back the piston, as therein
| mentioned, I prefer to use the arrangements for these purposes, as shewn

page_text: the vertical shaft C. The upper part of the latter passes through a
feeding pan E, and has on it blades or stirrers F; E is the feeding pan,
below which the cam G is fixed upon the vertical shaft C. The revolving
table containing the moulds is shewn at H, and the teeth on the outer
edge or periphery thereof at I. As before stated the teeth are of such
a depth that the cam G on the vertical shaft C will move the table the
proper proportion of the circumference, and passing on leave the same
at rest for as great a portion of the revolution of the upright shaft as
may be required. The pressing plate is shewn at J, and the steam
cylinder by which the compression is accomplished at K, which latter 1
is situated either below the compressing stamps L, as in my said previous
Invention, or as in that of the said Messieurs Couillard and Mageline.
In the former case the valve is by preference moved by a crank M, or
by an excentric or cam formed or fixed on the end of the shaft B. The
rod N moves the lever O. The lever P moving the valve Q is connected 1
to the lever O by the catch R, which when lifted throws the valve Q out
of gear. The valve Q can then be moved by the handle S.
employed for raising the compressing stamps is shewn at T.
The incline
For the removal of the compressed blocks it is preferred to place a
small cylinder U in the position shewn in the Drawings, a pipe V being 2
led from the back of the cylinder U into the lower part of the cylinder K.
A second pipe W is carried from the front of the cylinder U into the
valve chest, as shown in the Drawings, exhausting the steam at the
proper time.
On the admission of steam to the cylinder K the same
passes up the pipe Y, moving the piston and rod X, and pushing the 2
finished blocks off the table on to the travelling belt or plate. Upon
the discharge of the steam the valve Q is in such a position that the
steam passes up the pipe W and pushes back the piston and rod X.
At Y are shewn the exhaust pipe and safety holes for preventing the
piston from striking the cylinder cover.

Having thus described and ascertained the nature of my said In-
vention, and in what manner the same is to be performed, I would
observe in conclusion that I do not claim specifically any of the com-
binations and arrangements embraced by the said Patent of the said
Messieurs Couillard and Mageline, and by my said previous Patent; 3
but what I consider novel and original, and therefore claim as con-
stituting the Invention secured to me by the said herein-before in part
recited Letters Patent is, the combination and arrangement of parts

page_text: and mechanism (save as aforesaid), substantially as and for the purposes
herein-before described and set forth, or any mere modifications thereof.
In witness whereof, I, the said Samuel Arnold Luke, have here-
unto set my hand and seal, this Second day of March, in the year
of our Lord One thousand eight hundred and seventy-five.
