Year: 1874

page_text: LETTERS PATENT to Edward Richard Hollands, of No. 37, Stoke
Newington Green, South Hornsey, and Leonard William Cubitt,
of No. 62, Church Road, Islington, for the Invention of “IMPROVE-
MENTS IN THE CONSTRUCTION OF IRONS TO BE HEATED BY GAS.”
PROVISIONAL SPECIFICATION left by the said Edward Richard
Hollands and Leonard William Cubitt at the Office of the Com-
missioners of Patents, with their Petition, on the 29th October
1874.
We, EDWARD RICHARD HOLLANDS, of No. 37, Stoke Newington
Green, South Hornsey, and LEONARD WILLIAM CUBITT, of No. 62,
Churcli Road, Islington, do hereby declare the nature of the said In-
vention for "IMPROVEMENTS IN THE CONSTRUCTION OF IRONS TO BE HEATED BY
GAS," to be as follows:-

page_text: we form in the body or block of the iron, parallel and close to its bottom
surface or face, as many holes as there are burner tubes to be contained
within it, these holes may either be made transversely or longitudinally
of the body, by preference they are made longitudinally. In this case
they are open at the back end of the boby and pass along the iron
nearly to its opposite end; from each hole a slot is made passing in an
inclined direction towards the top of the body, where the slots all meet
together and form an open chamber. The top is covered over by a
plate, in which a hole is formed, through which the products of com-
bustion may pass away. Into each of the holes before mentioned is:
inserted a metal tube with a row of perforations along it to form a gas
burner. To the end of the iron is affixed a chamber connected by a
flexible tube with a gas supply pipe, and from this chamber gas passes
to each of the burner tubes contained within the iron.
Above the cover plate of the top of the iron, and at some distance from:
it may be carried a plate of non-conducting material, or a chamber con-
taining non-conducting material, and to the top of this plate or chamber
is carried the handle. The products of combustion from the burners at
the lower part of the iron impinge against the sides of the slots, which
incline upwards to the top of the iron, and pass out through the hole
before mentioned in the cover plate and escape at the sides between this
cover plate and the plate or chamber above it.
By constructing box irons to be heated in the manner above described
a great extent of heating surface is obtained and the bottom or face of
the irons is effectually heated without the necessity of employing a blast,
as heretofore, to direct gas flames on to the bottom of the iron. The
beat imparted to the burner tubes themselves is also taken up by the
metal body, and they thus serve to increase the heating surface of the
iron
SPECIFICATION in pursuance of the conditions of the Letters Patent, 3
filed by the said Edward Richard Hollands and Leonard William
Cubitt in the Great Seal Patent Office on the 28th April 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, EDWARD
RICHARD HOLLANDS, of No. 37, Stoke Newington Green, South
Hornsey, and LEONARD WILLIAM CUBITT, of No. 62, Church Road, 3
Islington, sond greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of October, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Edward Richard Hollands and
Leonard William Cubitt, Her special licence that we, the said Edward
Richards Hollands and Leonard William Cubitt, our exccutors, admini-
strators, and assigns, or such others as we, the said Edward Richard
Hollands and Leonard William Cubitt, 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 THE CONSTRUCTION.
OF IRONS TO BE HEATED BY GAS," upon the condition (amongst others) that
we, the said Edward Richard Hollands and Leonard William Cubitt,
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 be performed, and cause the same to be filed in the
Great Scal Patent Office within six calendar months next and immc-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Leonard William Cubitt, on behalf
of myself and the said Edward Richard Hollands, 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, that is to say :-
This Invention has for its object to improve the construction of irons
to be heated by gas burners contained within them. For this purpose
we form the burners in the bottom part of the body or block of the
iron, so that it takes up heat directly from the burners, thus the bottom
of the iron is effectually heated without the necessity of employing a
blast to direct the gas flames on to it. The hollow chamber formed in
the body of the iron above the burners is formed with its sides sloping
inwards for the heated gases to impinge against, and is open at the top.
Above the body or block is a cover with perforations for the escape of
the heated gases, and above this is a flat plate carrying the handle. We

page_text: also surround the sides of the iron with a casing to retain the heat.
Figures 1, 2, 3, 4, and 5 of the Drawings hereunto annexed shew various
views of an iron constructed in this manner.
Figure 1 is a side view of the iron; Figure 2, a longitudinal vertical
section; Figure 3, a transverse vertical section; and Figure 4, a plan
view of the iron; Figure 5 shows an under side view of the iron with
its bottom plate removed.
A is the body or block of the iron, cast with channels A' along its
under side; B, B, are perforations passing from these channels to the
hollow chamber O formed in the block. The channels at the back end
of the iron open into a cross passage D, which at one end opens into a
hollow chamber E formed at one side of the block. Into this chamber
is screwed the end of the gas supply pipe F, this pipe is supplied with
gas through a flexible tube, and directs a jet of gas into the passage D;
G, G, are openings in the chamber E to allow air to be carried in
along with the jet of gas; II is a plate rivetted on to the bottom of the
block and closing in the channels A' and D. The sides of the hollow
chamber Care made to incline inwards, as shown at Figure 3, so that the
heated gases from the burners may impinge against them if desired;
passages C* may be conducted from these sides to the top of the block,
or these passages may be omitted; I is a plate closing in the back end
of the chamber, a small opening I* being left to admit of lighting the
mixture of air and gas as it issues from the burner holes; K, K, are
two channels formed in the under side of the block at its front end,
these channels are open in front, and perforations are also made from
them into the hollow chamber C, and serve to admit air to it. The
hollow chamber C is open at the top, as shown at Figures 2 and 3, and
above it is a cover L with perforations for the escape of the heated
gases; M is an outer casing which surrounds the sides of the iron and
serves to retain the heat, a small space being left between it and the
sides of the block to contain heated air; N, N, are openings into this
space from the lower part of the chamber C. Above the top of the
outer casing is a plate O carrying the handle; this plate is held down to.
the block by bolts P, as shown; Q, Q, are openings at the top of the
outer casing to permit the heated gas to escape.
In place of the burner being formed of hollow passages, cast or
formed in the bottom of the body or block of the iron and of holės

page_text: bored from these passages into the hollow chamber of the body, the
burners may be formed of separate perforated tubes fitted into recesses
in the bottom of the body or block, as shown at Figure 6, which repre-
sents a cross section of the body or block of an iron formed in this
manner. When burner tubes are thus inserted into the bottom of the
body or block they may be supplied with gas through a trough-shaped
cover secured to the back end of the body, so as to communicate with
the ends of cach of the tubes.
Projections R, R, for the heated gases to impinge against may also if
desired be formed to stand up within the hollow chamber of the block
for the heated gases from the burners to impinge against, as is also
shewn in this cross section.
Having thus described the nature of our Invention, and the manner
of performing the same, we would have it understood that we claim,-
First. The construction of irons, substantially as herein-before
described and shown in the Drawings annexed.
Second. Forming the burners in the bottom of the body or block of
the iron, substantially as herein-before described, so that the heat from
the burners may be taken up directly by the bottom of the iron.
In witness whereof, I, the said Leonard William Cubitt, have here-
unto set my hand and seal, this Twenty-eighth day of April, in
the year of our Lord One thousand eight hundred and seventy-
five.
