IMPROVED MACHINERY OR APPARATUS FOR PREPARING MATERIALS FOR THE MANUFACTURE OF GLUE
Year: 1874

page_text: LETTERS PATENT to Thomas Cannon, of the Firm of Edward Cannon
& Sons, of the City of Dublin, Ireland, Glue Manufacturers, for
the Invention of "IMPROVED MACHINERY OR APPARATUS FOR PREPARING
MATERIALS FOR THE MANUFACTURE OF GLUE."
PROVISIONAL SPECIFICATION left by the said Thomas Cannon at the
Office of the Commissioners of Patents, with his Petition, on the
26th January 1874.
I, THOMAS CANNON, of the Firm of Edward Cannon & Sons, of the
City of Dublin, Ireland, Glue Manufacturers, do hereby declare the
nature of the said Invention for "IMPROVED MACHINERY OR APPARATUS FOR
PREPARING MATERIALS FOR THE MANUFACTURE OF GLUE," to be as follows:-
This Invention relates to an improved construction and arrangement
of machinery or apparatus for preparing materials for the manufacture
of glue.

page_text: The Invention consists mainly in an improved construction and
arrangement of the rotating tumbler or drum, in which the materials are
prepared or treated.
The tumbler as constructed according to my improvements differs
from the ordinary, at all times open, thick, wooden tumbler, in that it is
made of iron or other suitable metal, and is constructed so that it can
be used as an open or as a closed tumbler as required for the purposes
subsequently explained, and is divided into compartments by diagonal
plates of metal instead of of wood as hitherto.
My improvements therein consist further in forming or providing the
circumference of each compartment at one part with a doorway, which
is closed or shut by a hinged door secured by pins, and at another or
other parts with cuts, holes, slots, slits, or other perforations, which
being left uncovered form the said open tumbler, or which may be
covered by removable shutter doors to form the said closed tumbler. 1
The shaft on and with which this improved tumbler rotates is also made
of metal, and receives the inner edges of the metal diagonal plates, and
is made hollow with radiating slits or apertures leading through its
circumference to the compartments of the tumbler. The bearings of
the shaft are placed on side brick or other supports, between which the 2
improved tumbler is situated. At each of its ends the shaft is connected
with a system or arrangement of pipes (provided with three cocks or
taps, or with a three-way cock or tap), which communicate with a water
main, and also with an acid tank placed on suitable supports above the
tumbler.
The tumble as above constructed and arranged may be actuated by

page_text: by a double-acting or two separate pawls, and also a pinion in gear with
the driving wheel on the tumbler shaft.
After the compartments have been supplied with the materials and
the doors refastened the hand wheel is removed, and the pawl or pawls
ungeared, and the tumbler is driven during the subsequent processes of
washing, acidulating, or vitriolizing and rewashing the materials by
steam power as hitherto. At the time of the first of these processes the
shutter doors are removed from covering the perforations in the cir-
cumference of the tumbler, which is thus made an open tumbler, so that
the water which is admitted thereinto by the system of cocks and pipes
in communication with the water main, and through the perforations in
the tumbler shaft for the purposes of washing the materials shall carry
the lime and other impurities therefrom, and escape therewith through
the said circumferential perforations. At the time of the next process
the shutter doors are refastened over the perforations so as to make the
tumbler a closed tumbler, so that the vitriolizing liquor or diluted acid
which is admitted thereinto by the system of cocks and pipes in com-
munication with the acid tank, and through the perforations in the
tumbler shaft shall be retained therein until it is spent and has properly
performed its functions (for this purpose the inner surfaces of the
doors and shutter doors are provided at their edges with rubber bands,
which fit closely to the exterior surfaces of the tumbler, and prevents
escape of the acid), after which the shutter doors are again removed,
when the spent acid runs out through the circumferential perforations,
immediately after which the last process (which consists in rewashing
the materials thus previously treated) is performed in the same manner
as the first washing above described, and when that is completed the
water is turned off and the tumbler has imparted to it a number of extra
revolutions, which partially drain the water from the materials thus
fully prepared, so that they can be removed from the compartments on
the opposite side of the improved tumbler to that on which they were
fed thereinto.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Cannon in the Great Seal Patent Office on
the 17th July 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
CANNON, of the Firm of Edward Cannon & Sons, of the City of Dublin,
Ireland, Glue Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of January, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Thomas Cannon, Her special
licence that I, the said Thomas Cannon, my executors, administrators,
and assigns, or such others as I, the said Thomas Cannon, 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 "IMPROVED MACHINERY OR
APPARATUS FOR PREPARING MATERIALS FOR THE MANUFACTURE OF GLUE," upon
the condition (amongst others) that I, the said Thomas Cannon, 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 Cannon, 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 in writing, and on reference being had to the
accompanying Sheet of Drawings, that is to say:-
This Invention, which is illustrated on the accompanying Drawings
in Figures 1 to 4 relates to the construction and arrangement of
improved machinery or apparatus for preparing materials for the manu-
facture of glue.

page_text: The Invention consists mainly in an improved construction and
arrangement of the rotating tumbler or drum 1, in which the materials
are prepared or treated.
The tumbler as constructed according to my Invention differs from
the ordinary, at all times open, thick, wooden tumbler, in that it is
made of iron or other suitable metal, and is constructed so that it can
be used as an open or as a closed tumbler as required for the purposes
subsequently explained. It is however divided into compartment 2 by
diagonal plates 3, as hitherto (Figure 2).
My improvements therein consist further in forming or providing the
circumference of each compartment at one part with a doorway 4, which
is closed or shut by a hinged door 5 secured by pins 6, and at another
or other parts with holes 7 (or with cuts, slots, slits, or other equivalent
perforations), which being left uncovered (as at a, Figure 1) form the
said open tumbler, or which may be covered by removable shutter
doors 9 (as at 6, Figure 1) to form the said closed tumbler. The shaft 10,
on and with which this improved tumbler rotates, is made of metal, and
receives the inner edges of the diagonal plates 3, sec (Figure 3), and is
made hollow with radiating slits or apertures 11 leading through its
circumference to the compartments 2 of the tumbler. The bearings 12
of the shaft 10 are placed on side, brick, or other supports 13, between
which the improved tumbler is situated. At each of its ends the
shaft 10 is connected with a system or arrangement of pipes 14, 14*, 15,
(provided with three cocks or taps 16, 16*, 17, or with an equivalent
three-way cock or tap) of which those marked 15 (which are of iron)
communicate with a water main, and of which those marked 14 (which
are of lead, as are also the pipes 14*) communicate with an acid tank 18
placed on suitable supports 19 above the tumbler.
The tumbler as above constructed and arranged may be actuated by
the system of driving gear × heretofore in use for driving the ordinary
open wooden tumbler.
When commencing an operation of preparing the materials for
subsequent manufacture into glue it is desired to supply the com-
partments 2 of the improved tumbler 1 with the materials to be treated
or prepared, the doors 5 closing the doorways 4 thereof are separately
unpinned and let down to admit of the feeding in turn as they come
round. This operation is performed at the side c of the tumbler

page_text: (Figure 2) at the time of supplying the compartments 2; thus the
tumbler is turned in the proper direction by a hand or spoke wheel 20
placed on the squared end of a spindle or shaft 21 carrying a double-
acting ratchet wheel 22 controlled by a double-acting or two separate
pawls 23 and also a pinion 24 in gear with the driving wheel × on the
tumbler shaft 10.
After the compartments 2 have been supplied with the materials and
the doors 5 refastened by the pins 6 the hand wheel 20 is removed, and
the pawl or pawls 23 ungeared, and the tumbler is driven during the
subsequent processes of washing, acidulating, or vitriolizing and re-
washing the materials by steam power as hitherto. At the time of the
first of these processes the shutter doors 9 are removed from covering
the perforations 7 in. the circumference of the tumbler (as at a,
Figure 1), which is thus made an open tumbler, so that the water which
is admitted thereinto by the system of cocks 17, 16*, and pipes 15, 14*,
the former of each of which is in communication with the water main,
and through the perforations 11 in the tumbler shaft 10 for the purpose
of washing the materials, shall carry the lime and other impurities
therefrom, and escape therewith through the said perforations 7. At the
time of the next process the shutter doors 9 are refastened over the
perforations 7 (as at b, Figure 1), so as to make the tumbler a closed
tumbler, so that the vitriolizing liquor or diluted acid which is admitted
thereinto by the system of cocks 16, 16*, and pipes 14, 14*, the former
of each of which is in communication with the acid tank 18, and
through the perforations 11 in the tumbler shaft 10 shall be retained
therein until it is spent and has properly performed its functions, after
which the shutter doors 9 are again removed when it runs out through
the perforations 7, immediately after which the last process (which
consists in rewashing the materials thus previously treated) is performed
in the same manner as the first washing above described, and when that
is completed the water is turned off and the tumbler has imparted to it
a number of extra revolutions, which partially drain the water from the
materials thus fully prepared, so that they can be removed from the
compartments 2 at the side d (Figure 2) of the improved tumbler
opposite to that c on which they were fed thereinto.
Having now particularly described and ascertained the nature and
objects of my said Invention, together with the manner in which the
same is to be or may be performed or carried into practical effect, I

page_text: would remark in conclusion that I claim as my Invention, the above
described improvements in the construction and arrangement of
machinery or apparatus for preparing materials for the manufacture of
glue, substantially as described and as illustrated on the accompanying
Drawings or any equivalent modification thereof or therein.
In witness whereof, I, the said Thomas Cannon, have hereunto
set my hand and seal, this Fourteenth day of July, in the
year of our Lord One thousand eight hundred and seventy-
four.
