Year: 1854

page_text: LETTERS PATENT to Thomas Miller, of Fair Field Place, Stepney, in the
County of Middlesex, for the Invention of "IMPROVEMENTS IN APPARATUS
FOR RAISING COALS AND OTHER WEIGHTS FROM THE HOLDS OF SHIPS AND
OTHER PLACES."
Sealed the 16th February 1855, and dated the 21st August 1854.
PROVISIONAL SPECIFICATION left by the said Thomas Miller at the
Office of the Commissioners of Patents, with his Petition, on the
21st August 1854.
I, THOMAS MILLER, of Fair Field Place, Stepney, in the County of Middle-
sex, do hereby declare the nature of the Invention for "IMPROVEMENTS IN
APPARATUS FOR RAISING COALS AND OTHER WEIGHTS FROM THE HOLDS OF SHIPS AND
OTHER PLACES" to be as follows:-
This Invention has for its object a combination of apparatus to facilitate
the unloading of coals or other weights from the hold of ships or other places,
and such apparatus consists of a lever or spar, supported intermediately of its
length by an upright or standard, the point of support allowing the lever to
be moved in any direction, and also admitting of adjustment lengthwise of the
lever or spar. At the ends of the lever or spar are attached ropes, cords, or
chains, which are passed over gins or pulleys attached at or near the lower
ends of the upright or standard. The ropes, cords, or chains are then passed

page_text: over other pulleys at the ends of the lever or spar, and respectively attached,
the one to the weight to be raised, and the other to the barrel of a windlass,
which is supplied with a break, with which to arrest the ascent or descent of
the coals or other weight, as desired.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Miller in the Great Seal Patent Office on the
19th February 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
MILLER, of Fair Field Place, Stepney, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of August, in the year of our Lord
One thousand eight hundred and fifty-four, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Thomas Miller, Her special licence that I, the said Thomas Miller, my
executors, administrators, and assigns, or such others as I, the said Thomas
Miller, 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
RAISING COALS AND OTHER WEIGHTS FROM THE HOLDS OF SHIPS AND OTHER PLACES,"
upon the condition (amongst others) that I, the said Thomas Miller, by an
instrument in writing under my hand and seal, 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 Miller, do hereby declare the
nature of the 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 (that is to say) :-
This Invention has for its object a combination of apparatus to facilitate
the unloading of coals or other weights from the hold of ships or other places,
and such apparatus consists of a lever or spar, supported intermediately of its

page_text: length by an upright or standard, the point of support allowing the lever to
be moved in any direction, and also admitting of adjustment lengthwise of the
lever or spar.
At the ends of the lever or spar arc attached ropes, cords, or
chains, which are passed over gins or pulleys attached at or near the lower
ends of the upright or standard. The ropes, cords, or chains are then passed
over other pulleys at the ends of the lever or spar, and respectively attached,
the one to the weight to be raised, and the other to the barrel of a windlass,
which is supplied with a break, with which to arrest the ascent or descent of the
coals or other weight, as desired.
Having thus stated the nature of my said Invention, I will proceed to
describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
The Drawing shows a side elevation of apparatus, combined according to
my Invention, as applied on board a ship; but it will be evident that it may
be applied to any place where coals or other substances require to be raised.
a is a spar, iron beam, or lever, which, suspended by a chain 6, may be longer
or shorter than what is shewn, according as may be desired, and the spar, iron
beam, or lever may be arranged to protrude more on one side than the other
beyond the point of suspension. c is an upright, from the upper part of which
the spar, iron beam, or lever a is suspended. The upright c is sustained in
position by stays or ropes, as shown. d is a basket, or it may be other form of
apparatus, for containing the coals or other substances to be raised. The basket
or other form of apparatus used is suspended by a rope e, which passes over
the pulley f (attached to one end of the lever, iron beam, or spar a); it descends
down to and passes under the pulley g, and then ascends and is made fast to
the pulley frame f'. By this arrangement it will be seen that the basket d
moves through a greater space than the end of the lever or spar a, both when
that end of the lever or iron beam a is caused to rise and to descend. The
power for raising the coals or other substances is applied to the other end of
the lever, iron beam, or spar a, where a block h is attached, to the frame of
which one end of a rope i is fastened. The rope i descends from the block h
to and passes under the pulley j; the rope then rises and passes over the pulley
in the block h; it then descends and is wound on the barrel of the windlass k,
which is put in motion by manual labour or other power by crank handles;
or in place of using a windlass or barrel k, the rope may pass under a pulley
where the barrel is situated, and the end of the rope be held and pulled by
hand; or the rope, when it descends from the pulley h, may be worked by
hand.

page_text: Having thus described the nature of my said Invention, and the manner
of performing the same, I would have it understood that I make no claim to
any of the parts separately; but what I claim is, the combination herein
described.
In witness whereof, I, the said Thomas Miller, have hereunto set my
hand and seal, this Nineteenth day of February, in the year of our
Lord One thousand eight hundred and fifty-five.
THOMAS MILLER. (L.8.)
