page_text: LETTERS PATENT to Thomas Green, of the Phoenix Chemical Works,
Ouseburn, Newcastle-on-Tyne, for the Invention of "IMPROVEMENTS
IN THE TREATMENT OF BONES AND OTHER ARTICLES, AND IN APPARATUS FOR
THE SAME.
"
Sealed the 30th May 1873, and dated the 6th December 1872.
PROVISIONAL SPECIFICATION left by the said Thomas Green at the
I
Office of the Commissioners of Patents, with his Petition, on the
6th December 1872.
I, THOMAS GREEN, of the Phoenix Chemical Works, Ouseburn, New-
castle-on-Tyne, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE TREATMENT OF BONES AND OTHER ARTICLES, AND IN
APPARATUS FOR THE SAME," to be as follows:-
My Invention consists in the adaptation and application to the boiling
pans of mechanism or apparatus by means of which water and steam are
admitted to the pan as required for the process of boiling the bones,
and the pan is upset or tilted for the discharge of the bones after

page_text: Each
boiling. The pan is mounted on a hollow gudgeon at each end
supported by a suitable frame or standards, such hollow gudgeons
forming pivots or centres for the required movements of the pan.
gudgeon is furnished with a gland or stuffing box through one of which
and the gudgeon passes a steam pipe, and through the other a water
pipe, these pipes being adapted to convey the steam and water res-
pectively to the lower part of the interior of the pan, the steam pipe
being formed so as to direct a jet of steam upwards.
The pan is upset or tilted as required by means of a worm wheel or
wheels on one (or both) of the gudgeons worked by a worm mounted on
the frame or standard, and turned by a cranked handle or wheel fixed to
the axis of the worm. The pan is filled to within a short distance of
the top with the bones intended to be treated, and the bones are covered
by the water admitted through the water pipe and boiled by the steam
at about thirty pounds pressure admitted through the steam pipe until
all the grease is extracted. The waste water is then run off, and
the pan is upset or tilted by the means described in order to discharge
from it the bones that have been treated. After the pan has been
thereby emptied it is returned to its position and re-filled for a fresh
operation.
The above described apparatus may also be employed for boiling in

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Green in the Great Seal Patent Office on 25
the 5th June 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
GREEN, of the Chemical Works, Ouseburn, Newcastle-upon-Tyne, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 30
Letters Patent, bearing date the Sixth day of December, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Thomas Green, Her special licence

page_text: that I, the said Thomas Green, my executors, administrators, and
assigns, or such others as I, the said Thomas Green, 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
THE TREATMENT OF BONES AND OTHER ARTICLES, AND IN APPARATUS FOR THE
SAME," upon the condition (amongst others) that I, the said Thomas
Green, 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 Thomas Green, 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 Drawings hereunto
annexed, and to the letters and figures marked thereon, (that is to
say) :-
My Invention consists in the adaptation and application to the boiling
pans of mechanism or apparatus by means of which water and steam are
admitted to the pan as required, for the process of boiling the bones,
and the pan is upset or tilted for the discharge of the bones after
boiling. The pan is mounted on a hollow gudgeon at each end
supported by a suitable frame or standards, such hollow gudgeons
forming pivots or centres for the required movements of the pan. Each
gudgeon is furnished with a gland or stuffing box, through one of which
and the gudgeon passes a steam pipe, and through the other a water
pipe, these pipes being adapted to convey the steam and water res-
pectively to the lower part of the interior of the pan, the steam pipe
being formed so as to direct a jet of steam upwards.
The pan is upset or tilted as required by means of a worm wheel or
wheels on one (or both) of the gudgeons worked by a worm mounted on
the frame or standards, and turned by a cranked handle or wheel fixed
to the axis of the worm. Or the pan might be upset or tilted as required

page_text: by means of blocks and tackle. The pan is filled to within a short
distance of the top with the bones intended to be treated, and the bones
are covered by the water admitted through the water pipe and boiled by
the steam at about thirty pounds pressure admitted through the steam
pipe, until all the grease is extracted. The waste water is then run off,
and the pan is upset or tilted by the means described in order to dis-
charge from it the bones that have been treated. After the pan has
been thereby emptied it is returned to its position and re-filled for a
fresh operation.
The above described apparatus may also be employed for boiling in
the same manner other articles or materials requiring to be so treated,
and afterwards discharged from the pan.
Having thus stated the nature of the said Invention, I will proceed to
describe more particularly in what manner the same is to be performed
by the aid of the accompanying Drawings, in which is represented the
apparatus above referred to.

page_text: about thirty pounds pressure, by which means the boiling is to be
carried on until the grease or other foreign matter is extracted. The
waste water is then run off and the pan is tilted by turning the
spindle K, and acting on the worm wheel H through the worm I, and
the cleansed bones or material discharged or removed from the pan.
After emptying the pan is returned to its position by the same wheels
and refilled as required. In Fig. 2 the dotted lines shew the pan in a
tilted position.
Fig. 3 shews an arrangement of the steam pipe to admit steam into
the bottom of the pan, and Fig. 4 shews another arrangement for
admitting steam into the side of the pan.
Having thus described the nature of the said Invention and in what
manner the same is to be performed, I hereby declare that what I
claim as of my Invention is, the combination of parts of apparatus
applied to boiling pans whereby water and steam are admitted to the
pan as required for the process of boiling, and the pan is upset or tilted
as required for the discharge or removal of the bones or other articles or
materials after boiling, as herein-before described.
In witness whereof, I, the said Thomas Green, have hereunto set
my hand and seal, the Third day of June, in the year of our
Lord One thousand eight hundred and seventy-three.
Witness,
