AN IMPROVEMENT IN THE CONSTRUCTION OF SHIPS' STOVES
Year: 1860

page_text: LETTERS PATENT to Alfred Vincent Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Mechanical Draughts-
man, for the Invention of "AN IMPROVEMENT IN THE CONSTRUCTION OF SHIPS'
STOVES." A communication from abroad by George Alexander New, of
New York.
Sealed the 26th June 1860, and dated the 4th February 1860.
PROVISIONAL SPECIFICATION left by the said Alfred Vincent Newton
at the Office of the Commissioners of Patents, with his Petition, on the
4th February 1860.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Mechanical Draughtsman, do hereby declare the
nature of the said Invention for "AN IMPROVEMENT IN THE CONSTRUCTION OF
SHIPS' STOVES," to be as follows:-
The object of this Invention is to enable a stove for use on shipboard to be
kept upright without interruption to its draft, whatever may be the position or
movements of the vessel. To this end the stove is suspended on hollow pivot
joints in a swinging gimbal-like frame, part of which constitutes a flue for con-
ducting the smoke and products of combustion from the stove to the chimney,
the vent from this frame to the chimney being in one of the pivot joints by
which the frame is supported. The hollow pivot joints are formed each of
two pieces made separate from the stove and the frame, viz., a thimble and a

page_text: socket. The thimble consists of a short tube provided with a flanch having its
side edges made of dovetail form to fit into dovetail grooves in the bollow por-
tion of the frame, which constitutes the flue. The socket is a short tube large
enough to fit easily to the exterior of the thimble, and provided with lugs to
receive bolts by which it is bolted to the stove; openings are provided in the
stove opposite to the thimbles to connect them with its main flue. The socket
of the joint which is bolted to the chimney standard is made to fit the interior
of the thimble instead of the exterior, the object of this difference being to
bring the bearing at the top of the joint in both cases, and thus to keep the
weight of the stove as far as possible below the bearings.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alfred Vincent Newton in the Great Seal Patent Office
on the 4th August 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Mechanical Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of February, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Alfred Vincent Newton, Her special license that I, the said
Alfred Vincent Newton, my executors, administrators, and assigns, or such
others as I, the said Alfred Vincent Newton, 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 makė, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "AN IMPROVEMENT IN THE CONSTRUCTION OF SHIPS' STOVES," being a com-
munication from abroad, upon the condition (amongst others) that I, the said
Alfred Vincent Newton, 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 Alfred Vincent Newton, do hereby
declare the nature of the said Invention, and in what manner the same is to

page_text: be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say) :-
:-
The object of this Invention, as communicated to me by my foreign corre-
spondent, is to enable ships' stoves to retain an upright position without
interruption to the draft whatever during the rolling or pitching of the vessels
in which they may be set. To this end the stove is suspended on hollow
pivot joints in a swinging gimbal-like frame, part of which constitutes a flue
for conducting the smoke and products of combustion from the stove to the
chimney, the vent from this frame to the chimney being in one of the pivot
joints by which the frame is supported.
In the accompanying Drawing the Invention is illustrated as applied to a
cooking stove; Fig. 1 is a vertical section of the stove in the planes indicated
by the line a, a, in Fig. 3; Fig. 2 is a vertical section taken in the plane
indicated by the line a, a, in Fig. 3; Fig. 3 is a plan of the same, partly in
section; Figures 4 and 5 represent separately the two pieces of which the
hollow pivot joints are composed; similar letters of reference indicate corre-
sponding parts in the several Figures.
A is the stove; B is the swinging gimbal-like flue frame, in which the stove
is hung by the hollow pivot joints E, E, arranged opposite each other, one on
each side. One half of the said frame is made hollow to constitute a fluè a to
receive the smoke and gaseous products of combustion through the hollow
pivots E, E, and convey them to the chimney C. The frame B has its two
pivots h and D, by which it is hung in the standards F, F', arranged at right
angles to the hollow pivots E, E. The pivot h may be solid, but the pivot D,
which forms the joint or communication between the flue in the frame and the
chimney C erected upon the standard F' is hollow. The course of the draft
from the stove through the pivot joints E, E, flue a, and pivot joint D to the
chimney C is indicated by arrows. The hollow pivot joints E, E, and D are
formed each of two pieces, made separate from the stove and the frame B,
viz., a thimble 6 and a socket c. The thimbles b, b, consist each of a short
tube provided with a flanch d having its side edges made of dovetail-form
to fit (as shown in Fig. 3) into dovetail grooves in the hollow portion a of
the frame B which constitutes the flue, such portion a, having suitable
openings to form communication between the said thimbles and its interior.
The sockets c of the joints E, E, consist of short tubes, large enough to fit
easily to the exterior of their respective thimbles b, b, and are provided with
lugs f, f, to receive bolts e, e, by which they are bolted to the stove. Openings
are provided in the stove opposite to these thimbles to connect them with its

page_text: main flue g, as shown in Fig. 2. The socket c of the joint D, which is bolted
to the chimney standard F is made to fit the interior of the thimble 6 instead
of the exterior, as is the case in the joints E, E. The object of this difference
is to bring the bearing at the top of the joint in both cases, and thus to keep
the weight of the stove as far as possible below the bearings. In the construc-
tion of the stove and its frame B care should be taken that the pivots E, E, D, h,
be respectively so arranged that the stove will be as nearly balanced as prac
ticable, that it may hang as nearly as possible in an upright position, and the
.same position will be maintained in all the movements and changes of position
of the vessel, without disturbing the communication that is provided between
it and the chimney by the pivot joints E, E, flue a, and pivot joint D. Cabin
.stoves or any other stoves used on shipboard may be hung in the same manner
as the cooking stove represented. In some kinds of stoves it may be sufficient
to have but one of the pivots E, E, hollow.
Having now set forth the nature of the Invention of an improvement in
the construction of ships' stoves, as communicated to me from abroad, and
explained the manner of carrying the same into effect, I wish it to be under-
stood that under the above in part recited Letters Patent, I claim combining
a stove for use on shipboard with its chimney by means of hollow pivot joints
and a swinging gimbal-like tubular frame in the manner and for the purpose
herein specified..
In witness whereof, I the said Alfred Vincent Newton, have hereunto
set my hand and seal, the Fourth day of August, in the year of our
Lord One thousand eight hundred and sixty.
