IMPROVE- MENTS IN LOOMS FOR WEAVING
Year: 1878

page_text: LETTERS PATENT to Robert Hopwood Hutchinson, of Blackburn, in the
County of Lancaster, Cotton Manufacturer, for the Invention of "IMPROVE-
MENTS IN LOOMS FOR WEAVING."
Sealed the 9th July 1878, and dated the 15th January 1878.
PROVISIONAL SPECIFICATION left by the said Robert Hopwood Hutchinson
at the Office of the Commissioners of Patents on the 15th January 1878.
ROBERT HOPWOOD HUTCHINSON,. of Blackburn, in the County of Lancaster,
Cotton Manufacturer. "IMPROVEMENTS IN LOOMS FOR WEAVING."
This Invention relates to improved apparatus for self-actingly stopping the loom
when a predetermined length of cloth has been woven, in order that a coloured or
ornamental heading may be woven at each "cut" or length.
According to this my Invention, I employ gear wheels driven from the emery
roller; these give slow rotation to a disc having a slot therein in the direction of its
axis. Resting upon and supported by the periphery of the disc, is a rod to which
is attached a finger, the latter so long as the rod is supported by the disc, is above
or out of the way of a pusher attached to the front of the going part or slay; when
however the disc has completed a revolution, the end of the rod is over the slot in
the disc into which it falls, thus lowering the rod and bringing its finger in line
with the pusher referred to, which acts upon the finger, forcing the latter against a
lever or rod connected with the ordinary knocking-off apparatus, and the loom is
stopped. The falling rod may have a finger applied thereto, so that the latter may
fall upon the catch end of the weft fork, and so stop the loom.
When starting the loom again, the rod will be raised or lifted out of the slot, and
rests upon the disc clear of the slot hole. The speed of the rotation of the disc will
be regulated by charge wheels, according to the length of "cut" or length of cloth
required to be woven before the loom is stopped.

ROBERT HOPWOOD HUTCHINSON, of Blackburn, in the County of Lancaster,
Cotton Manufacturer. "IMPROVEMENTS IN LOOMS FOR WEAVING."
This Invention relates to improved apparatus for self-actingly stopping the loom
when a predetermined length of cloth has been woven, in order that a coloured or
ornamental heading may be woven at each "cut" or length.
According to this my Invention, I employ gear wheels driven from the emery
roller; these give a slow rotation to a disc having a slot cut therein in the direction
of its axis. Resting upon and supported by the periphery of the disc, is a rod to
which is attached a finger, the latter so long as the rod is supported by the disc, is
above or out of the way of pusher attached to the front of the going part or slay;
when however the disc has completed a revolution, the end of the rod is over the
slot in the disc into which it falls, this lowering the rod and bringing its finger in
line with the pusher referred to, which acts upon the finger, forcing the latter
against a lever or rod connected with the ordinary knocking-off apparatus, and the
loom is stopped. The falling rod may have a finger applied thereto, so that the
latter may fall upon the catch end of the weft fork and so stop the loom.
When starting the loom again, the rod will be raised or lifted out of the slot, and
rests upon the disc clear of the slot hole. The speed of the rotation of the disc will
be regulated by change wheels, according to the length of "cut" or length of cloth
required to be woven before the loom is stopped.
Such being the nature and object of this my said Invention, I will now proceed
to describe the same in detail, and in order that the Invention may be fully under-
stood, I have hereunto annexed two Sheets of Drawings illustrative thereof, and
have marked the same with figures of reference, in which Fig. 1 is end elevation
of part of a loom having my improvements applied thereto; Fig. 2 a plan view of
same; Fig. 3 end elevation of modified arrangement; Figs. 4, 5, 6, 7, 8, are modi-|
fications of driving apparatus; 9, 10, and 11 are details.
DESCRIPTION OF THE DRAWINGS.
I employ gear wheels 2, 3, 4, 5, 6, 7, driven from the emery roller 1; these give
slow rotation to a disc 8, having a slot 9 cut thereon in the direction of its axis 10.
Resting upon and supported by the periphery of the disc 8 is a rod 11, to which is
attached a finger 12, the latter so long as the rod is supported by the disc is above
or out of the way of pusher 13 attached to the front of the going part or slay 14;
when however the disc has completed a revolution, the end of the rod 11. is over
the slot 9 in the disc into which it falls, thus lowering the rod 11, and bringing its
finger 12 in line with the pusher 13 referred to, which acts upon the finger 12,
forcing the latter against a lever or rod 14 connected with the ordinary knocking
off apparatus 15, and the loom is stopped. The falling rod 11 may (in lieu of the
pusher 13) have a finger 16 applied thereto, so that the latter may fall upon the
catch rod of the weft fork 17, and so stop the loom; see Drawings, Fig. 3.
When starting the loom again, the rod will be raised or lifted out of the slot 9,
and rests upon the disc 8 clear of the slot hole. The speed of the rotation of the
disc will be regulated by change wheels 4 and 5, according to the length of the
"cut" or length of cloth required to be woven before the loom is stopped.
Figs. 4 and 5 shew disc (8) having spiral groove, the end of the rod 11 being
cranked and received within the groove, is drawn down and over the slot 9 into
which it falls. When the cut is woven, the rod 11 is then to be sprung back, and
so as to pass out of slot or hole to the top of the groove again.

page_text: Figs. 6 and 7 shew another means of driving the disc 8 from the emery roller 1
by worm, worm wheel and bevel wheels.
Fig. 8 shews catches and catch wheel.
Figs. 9, 10, and 11, show disc 8 drawn about full size.
Having thus fully described the nature and particulars of this my said Invention,
together with the manner in which the same is to be or may be performed or carried
into practical effect, I would have it understood that what I claim as my Invention
is, the use of the slotted disc 8 and rod 11, combined as and operating in the
manner and for purpose described, and as illustrated.
In witness whereof, I, the said Robert Hopwood Hutchinson, have hereunto
set my hand and seal, this Twelfth day of July, in the year of our Lord
One thousand eight hundred and seventy-eight.
