CERTAIN IMPROVEMENTS IN AND APPLICABLE TO LOOMS FOR WEAVING
Year: 1853

page_text: COMPLETE SPECIFICATION filed by Valentine Cocker and Reuben
Herbert at the Office of the Commissioners of Patents, with their
Petition and Declaration, on the 15th February 1858, pursuant to
the 9th section of the Patent Law Amendment Act, 1852.-A
communication.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we,
Valentine Cocker, of Salford, in the County of Lancaster, Machine
Maker, and Reuben Herbert, of Manchester, in the same County,
Commission Agent, do hereby declare the nature of our said Invention
of "CERTAIN IMPROVEMENTS IN AND APPLICABLE TO LOOMS FOR WEAVING,"
and in what manner the same is to be performed, to be particularly de-
scribed and ascertained in and by the following statement (that is
to say):
The nature of our Invention consists in applying a guard to the
reed-cap or other convenient part of the loom, in order to prevent the
shuttle leaving the shed when traversing from one shuttle box to the
other.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1, is a front view of part of a loom shewing the application
of the guard. Figure 2, is a section through the reed, shewing one
mode of constructing the guard; and Figure 3. is another section
shewing the guard thrown up to admit of the shuttle being taken out
of or put into the shed.
In Figure 1, A, A, is part of the loom sides; B, B, are the lay
swords; and C, is the lay bottom, shewn also in Figure 2; D,
is the reed, and E, the reed-cap. The red lines F, in Figures 2,
and 3, indicate the warp threads and the cloth; G, is the guard
which, in this instance, is shewn as being made of wood, but it
may be of iron or any other suitable material. I prefer to make
the guard of the same length as the reed; it is hinged to the
reed-cap, as shewn at G1, in Figure 1; but it may be longer or
shorter, if found desirable. G*, is a spring which acts on a catch
G³, and serves to retain the guard in the position shewn in Figure 2,
as long, as the loom is working, or until it is necessary to take the
shuttle out of the loom; when this is required the attendant by
lifting at the front edge of the guard causes the catch G³, to overcome
the spring G, and the guard then assumes the position shewn in Figure
3, being retained there as long as is required by the spring G³, acting
on the catch G³. In Figure 4, is shewn another mode of holding the
giard G, in the required positions; in this case the spring G, is
dispensed with, and a latch H, fixed to a bracket H', is employed
instead of it. The latch H, bears on the reed-cap when the guard is
down, and when the guard is up the latch assumes the position indi-
cated by dotted lines. When the shuttle has been replaced the guard
is brought down to its original position, and the work of the loom can
be resumed. By this means the shuttle is retained in the shed; con-
sequently, the injury to the shuttle, or to the loom, or to the operatives,
occasioned by the shuttle flying out, is entirely obviated; and when the
shuttle has to be taken from the loom to replace the bobbin, or for
other purposes, it can be done without 'loss of time or trouble.
Having. now described the nature of our Invention, and the mode of

page_text: carrying the same into effect, we declare that we claim the guard G,
and the inode of connecting it. to the reed-cap or any other convenient
part of the loom, when used in the manner and for the purposes herein-
before described.
In witness whereof, we, the said Valentine Cocker and Reuben
Herbert, have hereunto set our hands and seals, this Twelfth.
day of February, One thousand eight hundred and fifty-three.
