page_text: LETTERS PATENT to Frank Moline, 1, Berkeley Square, Bristol, and
Thomas Granger Stock, Arley Hill, Bristol, for the Invention of
"IMPROVEMENTS IN APPARATUS FOR FILLING SUGAR AND OTHER CASKS AND
AASTHA MYD CONTENTS DEDING THE FILLING
"
PROVISIONAL SPECIFICATION left by the said Frank Moline and
Thomas Granger Stock at the Office of the Commissioners of
Patents, with their Petition, on the 29th August 1873.
We, FRANK MOLINE, 1, Berkeley Square, Bristol, and: THOMAS
GRANGER STOCK, Arley Hill, Bristol, do hereby declare the nature of
the said Invention for. "IMPROVEMENTS IN APPARATUS FOR FILLING SUGAR
AND OTHER CASES AND FOR COMPRESSING THE CONTENTS DURING THE FILLING,"
to be as follows:
This Invention relates to apparatus for filling casks with sugar and
other similar substances and for compressing the contents during the
filling, the object being to dispense with manual labour as much as
possible and to expedite the filling and compressing operations.

page_text: The Invention consists of a frame of skeleton form between which
plunger rods are caused to rise by excentrics or cranks and are then
freed to fall and compress the contents of the cask, which cask is upon
a rotating table beneath. The rotation of the cask is in proportionate
relation to the filling operation, which is effected from a hopper or shoot
arranged above or by hand as found convenient.
The excentrics or cranks which lift the plungers and their rods are
actuated preferably by a band from some prime mover, the rods working
within guides, and also between sliding boxes to which pauls are
arranged for taking into teeth upon the rods. There are bolts upon the
boxes which in the up-stroke impinge against stops whereby the bolts
become shot downwards, and bulges or projections upon two of their
faces come into contact with the pawls and throw them out of the teeth,
the plungers or rammers being then free to fall. In their fall the boxes
travelling with them cause the bolts to impinge against other stops at
the bottom, the stops being on fixed parts of the framing so that the
pauls are freed and are caused .to take into the teeth again under the
action of springs or their equivalents. The pawls may have tongues upon
them to regulate their action, and to prevent injury to the teeth by the
suddenness of the release.
The plungers or rammers are in most cases a fixture upon the rods,
but they may be affixed to be removed when desired.
By this Invention as the cask becomes filled the rammers rise to the
same distance, consequently the pressure at each stroke is the same upon
the material within the cask, whether the cask is only partially or
wholly filled.
I do not limit myself to the method of releasing the plungers above
described, as this may be effected by the withdrawal of rollers or wheels.
from the rods in any suitable manner, particularly if the rods be raised
by frictional gearing, the casks rotating upon its table the while for the
equal distribution and the ramming of the material.

filed by the said Frank Moline and Thomas Granger Stock in the
Great Seal Patent Office on the 27th February 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FRANK
3 MOLINE, 1, Berkeley Square, Bristol, and THOMAS GRANGER STOCK,
Arley Hill, Bristol, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of August, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Frank Moline and Thomas Granger
Stock, Her special licence that we, the said Frank Moline and Thomas.
Granger Stock, our executors, administrators, and assigns, or such
others as we, the said Frank Moline and Thomas Granger Stock, 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. APPARATUS FOR FILLING SUGAR AND OTHER CASKS AND FOR COMPRESSING THE
CONTENTS DURING THE FILLING," upon the condition (amongst others) that
we, the said Frank Moline and Thomas Granger Stock, or one of us, our
executors or administrators, by an instrument in writing under our, or
one of 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 Great Seal Patent Office within six calendar months next. and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Frank Moline and Thomas Granger
Stock, 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 thereof, reference being
had to the Drawings hereunto annexed, that is to say :—
This Invention relates to apparatus for filling casks with sugar and
other similar substances and for compressing the contents during the

page_text: filling, the object being to dispense with manual labour as much as
possible and to expedite the filling and compressing operations.
The Invention consists of a frame of skeleton form between which
plunger rods are caused to rise by excentrics or cranks, and are then
freed to fall and compress the contents of the cask, which cask is upon
a rotating table beneath. The speed of rotation of the cask is in pro-
portionate relation to the filling operation which is effected from a
hopper or shoot arranged above or by hand as found convenient.
: .
•
The excentrics or cranks which lift the plungers and their rods are
actuated preferably by a band from some prime mover, the rods working
within guides, and also between sliding boxes to which pauls are
arranged for taking into teeth upon the rods. There are bolts upon the
boxes, which in the up-stroke come against stops whereby the bolts
become shot downwards, and bulges or projections upon two of their
faces come into contact with the pauls and throw them out of the teeth
the plungers or rammers being then free to fall. In their fall the boxes
travelling with them cause the bolts to come against other stops at the
bottom, the stops being on fixed parts of the framing, so that the pauls,
are set free and are caused to take into the teeth again under the action
of springs or their equivalents. The pauls may have tongues. upon them
to regulate their action, and to prevent injury to the teeth by the sud-
denness of the release.
· The plungers or rammers are in most cases a fixture upon the rods,
but they may be affixed to be removed when desired.
The method of carrying the Invention into effect is clearly shown in
the accompanying Sheet of Drawings, in which Figure 1 is a front-
view of a complete apparatus for compressing the contents, say, sugar
within a cask as the sugar is fed by hand (shovelling) or from a hopper
above.
- A, A, is the frame of skeleton form composed of standards united by
a cross bar B and a base plate C, the centre of which is open for the
reception of a revolving or turntable D upon which the cask E to be
filled is placed, substantially as shown, the table D being upon rollers-
F, F, at equidistance apart for the proper balancing of it and the cask.
thereon. On the bottom of the table is a bevil wheel G, and this is geared
into by a bevel pinion П upon a projecting end of a horizontal shaft I
supported in bearings within a kind of box J on one side of the frame

page_text: A, which shaft receives its motion of rotation by a band K upon its
band wheel L, and upon a band wheel M from a shaft N, or in some
other convenient manner. The shaft N is the main shaft of the
machine or apparatus, and it is driven by a band P upon its fast pulley
Qby a rear or an overhead motion.
The main shaft N has two excentrics R, R, upon it for producing an
up-and-down motion of the rods S, S, as in Figure 2, the lower ends of
which are pinned to boxes T, T, to impart to the boxes a corresponding
up-and-down motion, but between slides U, U, to ensure their vertical
action. These sliding boxes T, T, are provided with spring catch
and slip pauls V, V, which are in a piece with arms W, W, as shown
in. Figures 3 and 4. The pauls take into teeth X, X, upon rammer
shafts or stems Y, Y, for the lift of the rammers Z, Z, and are released
from the teeth, for the fall or ramming operation by the boxes taking
with them one or more bolts a, a, the top ends b, b, of which come
against projections c, c, of the cross pieces d, d, and remain stationary
while the boxes continue their upward motion under the action of the
eccentrics. This extra motion causes the arms W, W, to ride against
the bulged or projecting portions d', d', of the bolts a, a, and to open out,
taking the pauls V; V, out of the teeth X, X, and thereby permitting
the rammers 'to fall by their own weight to compress the contents of
the cask placed beneath them, the sugar or other material being sup-
plied and the cask rotating at the same time. After cach fall of a
rammer its box T partakes of a downward motion by the excentric R
and rod S, the box taking the bolt a with it, the bulges d', a, being still
between the arms W, W, and just before the box arrives at the bottom
of its stroke the bottom of the bolt comes against the stop piece e and
the bolt is thereby shot up to permit of the springs f, f, drawing or
pushing the pawls into the teeth of the rammer stem y for the next lift
of the rammer.
It will be seen that the motions of the bolt are very slight and that
the release of the rammers is very sensitive, the lift being always the
same whether the cask be full or empty or only partially filled, because
the teeth upon the stems are formed to suit the height of the tallest cask
that can be placed under the rammers, and upon the rotating table
the pressure of the stroke or force of the blow being also always the
same

page_text: The main shaft N is furnished with a loose pulley on to which the
band P can be thrown to put the apparatus out of work.
We do not limit ourselves to the method of releasing the plungers
above described, as this may be effected by the withdrawal of rollers or
wheels from the rods in any suitable manner, particularly if the rods be
raised by frictional gearing, the cask rotating upon its table the while
for the equal distribution and ramming of the material.
And having now described the nature of our said Invention and
in what manner the same is to be performed, we declare that we
claim,―
Firstly. Compressing sugar or other body or substance within rotating
casks or vessels by rammers which have an equable lift from an overhead
motion, and a free fall without reference to the height of the contents
of the vessel in the manner and by the apparatus described and shown.
Secondly. The special method of and appliances for releasing pawls 1
from the teeth of free falling rammers, and the method of re-engaging
such pawls and teeth, as and for the purposes set forth.
Thirdly. We claim the modifications referred to by which our
Invention, i.e., mechanically compressing the contents of casks and.
similar vessels while rotating can be effected, as set forth.
In witness whereof, we, the said Frank Moline and Thomas
Granger Stock, have hereunto set our lands and seals, this
Twenty-third day of February, One thousand eight hundred and
seventy-four.
