IMPROVEMENTS IN THE CONSTRUCTION OF CLOTH BEAMS FOR BEETLES
Year: 1856

page_text: LETTERS PATENT to John Musgrave, the younger, of the Globe Iron
Works, Bolton-le-Moors, in the County of Lancaster, Ironfounder, for the
Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF CLOTH BEAMS FOR
BEETLES."
Sealed the 31st March 1857, and dated tho 26th November 1856.
PROVISIONAL SPECIFICATION left by the said John Musgrave at the
Office of the Commissioners of Patents, with his Petition,, on the
26th November 1856.
I; JOHN MUSGRAVE, the younger, of the Globe Iron Works, Bolton-le-Moors,
in the County of Lancaster, Ironfounder, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF CLOTH BEAMS FOR
BEETLES," to be as follows:-
The nature of my Invention consists in constructing the cloth beams for
beetles of wrought-iron plates, rivetted or welded together; the centres of the
beams are either rivetted or otherwise attached to the ends of the beam, or an
axle passing through the beam and projecting at each end may be used. Tho
object of this improved construction of beam is to combine strength with
lightness. These beams have hitherto been made of wood, which is liable to
be injured by the stampers, or of cast iron, which is very heavy.

by the said John Musgrave in the Great Seal Patent Office on the

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOBN
MUSGRAVE, the younger, of the Globe Iron Works, Bolton-le-Moors, in the
County of Lancaster, Ironfounder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of November, in the year of our
Lord One thousand eight hundred and fifty-six, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Musgrave, Her special license that I, the said John Musgrave, my
executors, administrators, and assigns, or such others as I, the said John
Musgrave, my executors, administrators, and assigns, sbould 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 CONSTRUC-
TION OF CLOTH BEAMS FOR BEETLES," upon the condition (amongst others) that I,
the said John Musgrave, 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 Offico within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Musgrave, do hereby 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
(that is to say);
The nature of my Invention consists in constructing the cloth beams for
beetles of wrought-iron plates, rivetted or welded together; the centres of the
beams are either rivetted or otherwise attached to the ends of the beam, or an
axle passing through the beam and projecting at each end may be used.
The object of this improved construction of beam is to combine strength with
lightness. And in order that my Invention may be fully understood and
readily carried into effect, I will proceed to describe the accompanying Sheet
of Drawings, reference being had to the figures and letters marked thereon.
Fig. 1 is a longitudinal section, and Fig. 2 a transverse section, shewing
one mode of constructing my improved cloth beams for beetles. a is the

page_text: cylindrical part of the beam, consisting of a wrought-iron plate, bent to the
required form, and welded together at the seams; to each end of the cylindrical
part a is rivetted an angle iron b, and to these angle irons are rivetted the
flanches c, forged of one piece with the centres d.
Figs. 3 and 4 are two similar views of a modification in the mode of con-
structing my improved cloth beams; in this instance the cylindrical part a is
formed of two wrought-iron plates, bent to the required circle, and rivetted
together longitudinally, the angle irons b, flanges c, and centres d are as above
described. It is evident that the cylindrical part a may be formed of more
than two plates rivetted together, if preferred.
Figs. 5 and 6 are two similar views of another modification in the mode of
constructing my improved cloth beams. In this instance the cylindrical part a
is supposed to be welded together, as in Figs. 1 and 2, or it may be rivetted
together, as in Figs. 3 and 4; the ends of the cylindrical part are shewn
rivetted to the cast-iron ends e, which aro keyed on the axle f. The foregoing
description and the Drawings are sufficient to illustrate the peculiar character
of my Invention, but various other modifications in the construction might be
shewn. The object of my improvements is to combine strength with lightness
in the construction of cloth beams for beetles, such beams having hitherto
been made of wood, which is liable to be injured by the stampers of the beetle,
or of cast iron, which is very heavy, and renders the beams inconvenient for
moving about.
Having thus described the nature of my Invention, and the best means with
which I am acquainted for carrying out. the same in practice, I wish it to be
understood that I do not limit myself to the details herein set forth, as they
may be varied; but what I do claim is the use and application of wrought-
iron plates for forming the cylindrical portions of cloth beams for beetles.
In witness whereof, I, the said John Musgrave, the younger, have
hereunto set my hand and seal, this Twenty-third day of May, in the
year of our Lord One thousand eight hundred and fifty-seven.
Witness,
H. B. BARLOW,
