Overlooker, for the Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING,
AND IN APPARATUS CONNECTED THEREWITH."

PROVISIONAL SPECIFICATION left by the said John Webster at the Office
of the Commissioners of Patents on the 19th April 1879.
JOHN WEBSTER, of Bradford, in the County of York, Overlooker. " IMPROVE-
MENTS IN LOOMS FOR WEAVING, AND IN APPARATUS CONNECTED THEREWITH."
My Invention relates to fitting on the hand rails of looms shuttle guards which
check the shuttles when flying out of their looms, causing them to fall downwards,
and preventing them flying across to other weavers attending other looms, which
has frequently caused serious accidents and damages.
For this purpose I fix two rods in small plates or levers; the rods are fitted at a
suitable distance apart and extend nearly across the hand rail of the loom; the
ends of the levers are formed with studs which work in small staples fixed near the
ends of the hand rail, and near the bottom of the face of the hand rail the studs
form the hinges of the guard or rods fitted in the small levers; one of these levers
is made on the top with notches, in which is placed a pawl to keep the guard down
and in checking position; the pawl is fitted and works in a bearer fixed near the
top of the hand rail, and is actuated by the weaver who puts the pawl in gear or
out of gear of the notches; directly the pawl is released from the notch in which it
has been placed the guard opens and is forced against the front surface of the hand
rail by an india rubber band which is fixed to the end hand rail and passed over
two small pullies fitted on the top of the hand rail; the end of the india rubber
band or spring is secured to a string which is fastened to the end of the small guard
lever not having any notches; or the end of the band can be secured by a wire or
wires; the india rubber spring keeps the guard against the face of the hand rail
during the time the weaver replaces the shuttle or a shuttle, and directly the
weaving operations are ready the weaver lowers the guard and places the pawl in
any suitable notch to give the required position to the guard; the loom is then.

it to fly downwards, preventing accidents and damage.
A rod or band can be attached or fixed to the pawl, and connected by a suitable
gear to the stop motion of the loom, and automatically raise the guard on the stop-
page of the loom. A spiral spring enclosed in a box can be employed instead of
the india rubber band, and the india rubber band can be passed over one pulley
instead of two.

MENTS IN LOOMS FOR WEAVING, AND IN APPARATUS CONNECTED THEREWITH."
My Invention relates to fitting on the hand rails of looms adjustable shuttle
guards, which check the shuttles when flying out of the race of the loom and
preventing their flying across the gate to the danger of weavers attending other
looms.
For this purpose I affix two rods in small plates or levers; the rods are fitted at
a distance apart, according to the size of the shuttle, and extend nearly across the
hand rail of the loom; the ends of the levers are provided with studs fitted to small
staples fixed near the ends of the hand rail; the studs form the hinges of the guard
or rods fitted in the small levers; one of these levers is notched on its upper edge,
in which notches is placed a pawl or holding catch to keep the guard down and in
checking position; the pawl is fitted and hinged to a bearer fixed near the top of
the hand rail. The weaver puts the pawl in gear or out of gear of the notches
when adjusting the guard, and directly the pawl is released from the notch in
which it has been placed the guard is folded against the front surface of the hand
rail by an india-rubber band or spring fixed near the end of the band rail; the
india rubber or metallic spring keeps the guard against the face of the hand rail
during the time the weaver replaces the shuttle and when piecing up broken ends,
and directly the loom is ready for working the weaver lowers the guard and places
the pawl in any suitable notch to give the required position to the guard; the loom
is when started and the guard is in position to check and prevent the flying out of
the shuttle and divert it downwards, preventing accidents and damage.
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 a Sheet of Drawings, and have marked the same
with figures and letters of reference, the same figure referring to the same or like
parts in the several views.

page_text: DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a plan view of hand rail of loom having my improved adjustable guard
applied thereto; Fig. 2 is an end view of same; Fig. 3 shews guard in raised
position. At A is the guard; B, an india rubber spring; C, a holding catch or
pawl engaging with the notches in the end D of guard. At Fig. 4 twisted hollow
rib springs E are employed. At Figs. 5 & 6 a spiral spring F is employed, and
when the guard is to be placed in the raised position it is slided endwise so as to
draw the pin G out of a bole H formed in the bearer bracket J (see Fig. 6), and on
raising the guard the pin G enters the hole K, the expansion of the spring thus
keeping the guard in close contact with the bearer J.
Having thus fully described the nature and particulars of this my Invention, I
would have it understood that I do not limit the same to the exact details
described and shewn, as such may be varied without departing from the Inven-
tion, nor do I claim the use of fixed guards for purpose aforesaid, as such are not
new, what I do claim is,-
The application and use of guards adjustable in manner and for purposes borein
described.
In witness whereof, I, the said John Webster, have hereunto set my hand and
seal, this Fifteenth day of October, in the year of our Lord One thousand
eight hundred and seventy nine.
