Year: 1868

page_text: LETTERS PATENT to John Alcock Farrar, of Hartlepool, in the County
of Durham, Master Mariner, and Benjamin Ralph Huntley, of
Hartlepool, aforesaid, Ship Chandler, for the Invention of "IMPROVE-
MENTS IN THE HATCHES AND CABIN TOPS OF SHIPS FOR VENTILATING AND
OTHER PURPOSES."
Sealed the 13th April 1869, and dated the 20th October 1868.
PROVISIONAL SPECIFICATION left by the said John Alcock Farrar
and Benjamin Ralph Huntley at the Office of the Commissioners of
Patents, with their Petition, on the 20th October 1868.
WC, JOHN ALCOCK FARRAR, of Hartlepool, in the County of Durham,
Master Mariner, and Benjamin Ralph Huntley, of Hartlepool, aforesaid,
Ship Chandler, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE HATCHES AND CABIN TOPS OF SHIPS FOR VENTILATING
AND OTHER PURPOSES," to be as follows:-
other
The hatches are proposed to be made of iron or steel or
metal, and the hatches are proposed to be fastened to the combings
by means of a clamp over the joining of each hatch. The hatches will
be made water-tight by having india-rubber, gutta percha, tarred felt,

page_text: or leather linings or packings at every joint of the hatches, so that
when the clamps are on the hatches are perfectly water-tight. On
the top of one or more of the hatches or cabins it is proposed to have
a man-hole of any height or width made of iron or steel or other
metal in a tubular or other shape with four or more tubes or ventilators
attached thereto, or making the man-hole a ventilator by enclosing
therein a smaller tube with openings, which openings can be closed
at any time in case of bad weather. The man-holo is to be used as
a ventilator for the cabins of ships, thereby dispensing with the use
of wind sails, and also as a means of entering the hold for trimming
or discharging the cargo or shifting the same without lifting or taking
off or removing the hatches, the top or cover of the man-hole or a
portion thereof to be made of rough plate glass to give light below,
and to have a hinge attached thereto for the purpose of opening
the same; when not in use the top or cover of the man-hole or
ventilator is to be fastened, screwed, or bolted down. The hatches
proposed will be much stronger, tighter, and lighter than the hatches
now in use, and they will also entirely do away with tarpaulings,
battens, &c.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Alcock Farrar and Benjamin Ralph Huntley
in the Great Seal Patent Office on the 19th April 1869.

page_text: 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 HATCHES AND CABIN TOPS OF SHIPS FOR VENTILATING AND
OTHER PURPOSES," upon the condition (amongst others) that we, the said
John Alcock Farrar and Benjamin Ralph Huntley, our executors or
administrators, by an instrument in writing under 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 bo
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 John Alcock Farrar and Benjamin
Ralph Huntley, 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:—
The hatches are proposed to be made of iron or steel or other metal,
and the hatches are proposed to be fastened to the combings by
means of a clamp over the joining of cach hatch. The hatches will
be made water-tight by having india-rubber, gutta percha, tarred felt,
or leather linings or packings at every joint of the hatches so that
when the clamps are on the hatches are perfectly water-tight. On
the top of one or more of the hatches or cabins it is proposed to have
a man-hole of any height or width, made of iron or steel, or other
metal in a tubular or other shape, with four or more tubes or ventilators
attached thereto, or making the man-hole a ventilator by enclosing
therein a smaller tube with openings, which openings can be closed
at any time in case of bad weather. The man-hole is to be used as a
ventilator for the cabins of ships, thereby dispensing with the use
of wind sails, and also as a means of entering the hold for trimming
or discharging the cargo, or shifting the same
without lifting or
taking off or removing the hatches, the top or cover of the man-
hole or a portion thereof to be made of rough plate glass to give
light below, and to have a hinge attached thereto for the purpose of
opening the same; when not in use the top or cover of the man-
hole or ventilator is to be fastened, screwed, or bolted down. The
hatches proposed will be much stronger, tighter, and lighter than

tarpaulins, battens, &c.
Having thus stated the nature of our said Invention, we will proceed
more fully to describe tlie manner of making the same.
DESCRIPTION OF THE DRAWINGS.
A (Fig 1) shews the combings of hatchways on deck, to which a
metal flange B is bolted or screwed; C, C, C, are the hatches screwed
with bolts and nuts to the flanges B, which are made perfectly water-
tight with india-rubber or other packing between the flanges D; the
ventilator is attached to one segment of the hatches C, C, C, with a
glass top E; F is a band fitted round the top G, provided with openings
at equal distances. By turning the handles H, H, the openings can
be wholly or partly opened according to the requirements of ventilation
or quite closed for keeping sea water from getting to the cargo.
The ventilator (Fig. 2) is made of two bell-mouthed cylinders or
tubes, one within the other, with a flange fitted to the same for screwing
or bolting to the hatches C, C, C; the flange J, J, is the ventilating
or air passage.
In witness whereof, I, the said Benjamin Ralph Huntley, on
behalf of myself and of the said John Alcock Farrar, have
hereunto set my hand and seal, this Fourteenth day of April
in the year of our Lord One thousand eight, hundred and sixty-
ninc:
