Year: 1853

page_text: PROVISIONAL SPECIFICATION left by the said James. Boydell
at the Office of the Commissioners of. Patents, with his Petition,
on the 20th December 1858..
I, JAMES BOYDELL of Gloucester Crescent, in the County of
5 Middlesex, do hereby declare the nature of the Invention for "IM-
PROVEMENTS IN THE MANUFACTURE OF WROUGHT IRON FRAMES" to be as
follows:
The object of this Invention is to obtain and use a section of wrought
iron bars where frames of glass or other material are used, by means
of which frames of hand glass lanterns and other articles may be formed

page_text: and go together with more convenience than heretofore, and allow of
the parts of a frame being packed in a smaller compass than when
ordinary sections of iron bars are used. For this purpose I roll wrought
iron bars with a longitudinal groove at each edge suitable for the sliding
in of the panuel of glass or other material; and in order to make them
into the proper form for the uprights of the frame of a hand glass or
other article, I further-roll such bars so as to bend them into angle iron.
If for a square frame the angle iron is bent so that the pannels will
come at right angles; and where tlie sides of the frames are more than
four, then the iron bars are bent to the angle required for the 'pannels
to stand in respect to each other at the proper angles for the number
of sides.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Boydell in the Great Seal Patent Office
. on the 20th June 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JAMES BOYDELL, of Gloucester Crescent, in the County of Middlesex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of December, in the
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said James Boydell, Her special
licence that I, the said James Boydell, my executors, administrators,
and assigns, or such others as I, the said James Boydell, 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 THE MANUFACTURE OF WROUGHT IRON FRAMES," upon the condition.
(amongst others) that I, the said James Boydell, by an instrument

page_text: 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. James Boydell, 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) :-
The object of this Invention is to obtain and use a section of wrought
iron bars where pannels of glass or other material are used, by means
of which frames. of hand glass lanterns and other articles may be
formed and go together with more convenience than heretofore, and
allow of the parts of a frame being packed in a sinaller compass than
when ordinary sections of iron bars are used. For this purpose I roll
wrought iron bars with a longitudinal groove at each end suitable for
the sliding in of the pannel of glass or other material; and in order to
make them into the proper form for the uprights of the frame of a hand
glass or other article, I further roll such bars so as to bend them into
angle iron. If for a square frame, the angle iron is bent so that the
pannels will come at right angles; and where the sides of the frames
are more than four, then the iron bars are bent to the angle required
for the pannels to stand in respect to each other at the proper angles
for the number of sides.
Having thus stated the nature of my said Invention, I will proceed
to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figures 1, 2, 3, and 4, show four sections of iron bars such as I use
in constructing frames of hand glasses, lanterns, and other articles
having pannels of glass fixed into them. The object of the Invention
is to employ in the making of frames to receive pannels of glass bars of
wrought iron formed with grooves so as to admit of glass being slid
into grooves, and to require as little putty or stopping as may be. In
some instances the iron bars are rolled with one groove to receive one

page_text: edge of a pannel of glass, and in other cases the bars are rolled with a
groove at each of its two edges so as to receive the edges of two
pannels of glass, and where only one groove is made to a bar, then there
is also a channel or part of a groove to receive the edge of another
pannel of glass.
bars.
Figure 1 shows a section of bar which I use in forming frames for
hand glasses, lanterns, and other articles, which section of bar has a
complete groove a, and a channel or part groove b. The complete
groove a, would require little or no putty or stopping material, and the
part groove b, will require stopping in like manner to ordinary sash
The section of iron bar, Figure 2, is suitable for forming
hand glasses, lanterns, or other frames, with numerous sides; this bar
is formed with two grooves a, a, which will require little or no stopping
material, and it will only require stopping material when it is desired
absolutely to exclude the air and weather. Figures 3 and 4 show two
sections of bars; they are similar in form, so far as having two grooves
a, a, to allow of glass being slid into them, but they are bent to different
angles, according as there are to be four or more sides to the frame
into which such bars are to be made. Figure 5 shows an exterior view
of a hand glass; Figure 6 is a plan thereof; Figure 7 is a vertical
section, and Figure 8, a horizontal section of the same.
or bars c, c, are formed at their lower ends with screws which pass
through the lower horizontal bars d, d, and are fixed thereto by screw
nuts e, as shewn. The bars or uprights c, are bent towards their upper
ends, and they are combined by the bars f, and screws g, and by the
bar h, and screws 7, by which arrangement the frames of hand glasses
may be readily packed in a small space. The bars or uprights c, are
made of the section of bar, Figure 1, but in place thereof the section
of bar, Figure 3, may be used. Figure 9, shows a horizontal section
of the frame of a hand glass, or of a lantern, or other frame, to receive
pannels of glass, and the parts may be put together in a similar manner
to that above described, when desired for convenience of packing in a
small space, or these bars, as well as the other sections of bars, may be
put together in any convenient manner, to form the character of frame
desired.

is, the manufacture herein described of wrought iron frames for receiving
pannels of glass or other materials.
