AN IMPROVED APPARATUS FOR FORMING OR REPAIRING THE MOUTHS OF BOILERS OR OTHER TUBES
Year: 1865

page_text: LETTERS PATENT to George Reverdy Ghiselin, of No. 445, West Strand,
in the County of Middlesex, Gentleman, for the Invention of "AN
IMPROVED APPARATUS FOR FORMING OR REPAIRING THE MOUTHS OF BOILERS OR
OTHER TUBES." A communication from abroad by Edward Clark, of New
York, in the United States of America.
Sealed the 17th April 1866, and dated the 19th October 1865.
PROVISIONAL SPECIFICATION left by the said George Reverdy Ghiselin
at the Office of the Commissioners of Patents, with his Petition, on the
19th October 1865.
I, GEORGE REVERDY GHISELIN, of No. 445, West Strand, in the County
of Middlesex, Gentleman, do hereby declare the nature of the said Invention
for "AN IMPROVED APPARATUS FOR FORMING OR REPAIRING THE MOUTHS OF BOILER
AND OTHER TUBES," to be as follows:-
>
My Invention consists of the combination of a short tube about three
inches long made of cast iron or other suitable metal and a split collar or
gland, as herein-after mentioned. The tube has a flange or lip at one end and
is of conical form, that is, it is of less diameter at the other end than it is at
the flange end. The spring collar or gland which is cylindrical is composed
of two pieces of metal split longitudinally and made of wrought iron or other

page_text: suitable metal, and the end of one of them is turned back or lapped over to about
the width of an inch and a half over the other piece of metal, which is of
shorter length and surrounds it. The gland so formed is put over the flange
tube so that the lapped end shall be at the smallest end of the flange tube,
and it is then ready for use. When it is desired to repair the end or mouth
of the boiler tube or flue of a steam engine, the flange tube with the gland
thereon as aforesaid is forced into the end or mouth of the boiler tube,
and by such pressure of the flange tube the gland is expanded against
the interior of the boiler flue and fixed, and the mouth is thus formed or
repaired.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Reverdy Ghiselin in the Great Seal Patent Office
on the 19th April 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
REVERDY GHISELIN, of No. 445, West Strand, in the County of Middlesex,
Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of October, in the year of our
Lord One thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said George Reverdy Ghiselin, Her special licence that I, the said George
Reverdy Ghiselin, my executors, administrators, and assigns, or such others as
I, the said George Reverdy Ghiselin, 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
"AN IMPROVED APPARATUS FOR FORMING OR REPAIRING THE MOUTHS OF BOILER
AND OTHER TUBES," upon the condition (amongst others) that I, the said
George Reverdy Ghiselin, my executors or administrators, by an instrument in
writing under my, 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 I, the said George Reverdy Ghiselin, do hereby

page_text: declare the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement and accompanying Drawings, that is to say: -:
My Invention consists of the combination of a short tube about three inches
long, made of cast iron or other suitable, metal, and a split collar or gland
herein-after mentioned. The tube has a flange or lip at one end and is of
conical form, that is, it is of less diameter at the other end than it is at the
flange end. The spring collar or gland, which is cylindrical, is composed of
two pieces of metal split longitudinally and made of wrought iron or other
suitable metal, and the end of one of them is turned back or lapped over to
about the width of an inch and a half over the other piece of metal, which is
of shorter length and surrounds it; and the gland so formed is put over the
flange tube so that the lapped end shall be at the smallest end of the flange
tube, and it is then ready for use. When it is desired to repair the end or
mouth of the boiler tube or flue of a steam engine, the flange tube with the
gland thereon as aforesaid is forced into the end or mouth of the boiler tube,
and by such pressure of the flange tube the gland is expanded against
the interior of the boiler flue and fixed, and the mouth is thus formed or
repaired.
My Invention will be better understood by reference to the Sheet of
Drawings, and the figures and letters marked thereon.
Figure 1 is a longitudinal section of a boiler tube and corresponding section
of the tube sheet, and of the split collar or gland, and of the short tube, in-
cluding a side view of the apparatus (shewn in Figure 5) by which the split
collar or gland is drawn into its place; Figure 2 is a section of the split collar
or gland; Figure 8 is a top or edge view thereof; Figure 4 is a side view of
the short tube with its flange or lip; Figure 5 is a longitudinal view of the
contrivance I use for drawing the split collar or gland into its required
position, but I do not claim such contrivance as part of my Invention.
The same letters of reference are applicable to the same parts in each
Figure.
A is the short tube, with its flange or lip B, the boiler tube in the tube
sheet; C, C, is the split collar or gland, composed of two rings or pieces of
metal; D is a screw bolt with a nut E and washer F, and having pivoted to
it by a pin G a head composed of 2 pieces of plate iron or steel H, H, of
nearly semicircular form, of just sufficient length to permit it to be passed
along the tube B. When those two pieces of metal have reached the position
sbewn by the red line, Figure 1, their weight will cause them to drop or fall
into the position shewn by the black line in Figure 1; the washer and nut

page_text: are then put on and the nut screwed up to draw the gland over the short tube
sufficiently to close any aperture.
I am aware that arrangements for 'similar objects have already been in use,
but I aver that this my Invention essentially differs from all previous arrange-
ments, as my Invention of an. improved apparatus for forming and repairing
the mouths of boiler or other tubes consists of the combination of a short tube
with its flange or lip and a split collar or gland composed of two rings or
pieces of metal split longitudinally, and having one end of one of, such rings
turned back or lapped over the other ring, as herein-before mentioned and
described.
In witness whereof, I, the said George Reverdy Ghiselin, have hereunto
set my hand and seal, this Eighteenth day of April, in the year of
.. Lord One thousand eight hundred and sixty-six.
GEO. R. GHISELIN. (L.s.)
