Improvements in Looms for Weaving.
I CHARLES THOMPSON of Otley Road Baildon, near Bradford, in the County of
York, Mill Furnisher, do hereby declare the nature of this invention to be as
follows:-
"
This invention relates, firstly: To an improved guard for preventing the shuttle
'flying out" when the loom is in motion, the said guard being removed, and leaving
the race open, as soon as the loon 15 stopped. Secondly: To an improved warp beam,
and appliances connected therewith, by the use of which the warps can be woven close
up to the healds whereby great saving in warp ends is effected. Thirdly: To further
improvements in the brakes of looms for weaving for which Her Majesty's Roval
Letters Patent were granted to me on the 8th day of July 1882 and numbered 3249,
whereby less strain, and consequently wear and tear is put on the loom when the
brake is applied
According to this any said invention hinged to the hand rail of the loom is a flat
strip or bar of wood of section and to one end of this bar of wood is attached a
strip of leather or wire one end of which passes over the top of the hand rail the other
end passing below the same. Fixed to the back of the hand rail is a small grooved
palley over which the strip of leather or wire which passes over the top of the hand
rail is passed; the strip of leather or wire which passes under the hand rail is carried
round the same pulley the free ends of the strip are secured to cords, or wires the
lower ends of which are attached to two lovers working on a fulcrum stud fixed to the
end frame or front rail of the loom, the other end of the levers are connected by wire
or cord to two bell crank leveis carried on the front rail, or end frame of the loom,
the other ends of the bell crank levers are connected by wire or cords one to the top
handle direct and the other to a small slotted lever on the loom end and from hence to
the stop handle. So that when the stop handle is moved to start the loom the bar of
wood first mentioned is drawn down on its hinges by the levers and connections and
being of
section pads against and fits closely to the hand rail forming a cover
over the shuttle race and preventing the shuttle from flying out. When the stop
handle is moved in the opposite direction to stop the loom the bar of wood is turned
back on its hinge close to the hand rail leaving the shuttle race open. Instead of the
lever connections for raising or lowering the bar of wood, I, in some cases prefer to
use a spring for drawing down the bar of wood, or for raising the same when the
pressure is taken off by moving the stop handle in which case one end of the strip of
leather or wire first herein mentioned is connected by cord or otherwise to a spiral
spring attached to the slay sword or other convenient part of the loom.
The improved warp beam and appliances connected therewith are designed for the
purpose of allowing the warps on the beams to be woven close up to the healds, and
thus prevent loss and waste of "ends" and to dispense with the tying of the warp
bean, which is a tedious and uncertain operation by reason of the varying strength of
cords or strings employed. According to my invention the warp beam rod is attached
to the warp beam by means of steel ribbons (preferably two) one of their ends being
secured to the warp beam, and a loop is formed in the free ends through which loop
the warp beam rod is passed and thereby securely held, the steel ribbons being wound
two three or more times round the warp beam, according to the distance between the
latter, and the healds, and the warp beam rod is placed in the race of the beam as
usual.
The improvements in brakes of looms for weaving consist of appliances for easing
the strain on, and taking pressure off the brake when the loom is stopped. In
Specification No. 3249 the brake is applied by a neb turning on its fulcrum stuð

page_text: To ease the strain, or jar on stopping
the loom the neb is continued at the opposite side of the fulcrum so as to form a lever,
to the end of which a spiral spring is attached the other end of which is fixed to the
front rail, or end frame of the loom so that when the brake is applied the spring is
extended, and its tendancy is to draw back the brake shoe from the brake wheel, and
the brake is cased in its action and less strain is put upon the soveral parts.
when operated by the frog and connections:

Improvements in Looms for Weaving.
I CHARLES THOMPSON of Otley Road, Baildon near Bradford in the County of
York, Mill Furnisher, do hereby declare the nature of this invention and in what
imanner the saino is to be performed, to be particularly described and ascertained in
and by the following statement :-
This invention relates first to an improved guard for preventing the shuttle flying
out when the loom is in motion, the said guard being removed, and leaving the race
open, as soon as the loom is stopped.
Secondly. To an improved waip beam and appliances connected therewith, by the
use of which the warps can be woven close up to the healds by which great saving in
warp ends is effected."
According to this my said invention hinged to the hand rail of the loom is a flat
strip or bar of wood of section and to one end of this bar of wood is attached a
strip of leather, or wire one end of which passes over the top of the hand rail the other
end passing below the same. Fixed to the back of the hind rail is a small grooved
pulley over which the strip of leather or wire which passes over the top of the hand
rail is passed, the strip of leather or wire which passes under the hand rail is carried
round the same or a separate pulley the free ends of the strip are secured to cords or
wires the lower ends of which are passed round a guide pulley and attached to a lever
working on a fulcrum stud fixed to the end frame or front rail of the loom the other
end of the lever is connected by a second lever mounted on the front rail or end fiame
of the loom, the other ends of the second lever is connected by wire or stud to the
stop handle direct. So that when the stop handle is moved to start the loom the bar
of wood first mentioned is drawn down on its hinges by the lovers and connections
and being of
section pads against and fits closely to the hand rail forming a

stop handle is moved in the opposite direction to stop the loom the bar of wood is
turned back on its hinge close to the hand rail leaving the shuttle race open. Instead
of the lever connections for raising or lowering the bar of wood, I in some cases
prefer to use a spring for drawing down the bar of wood, or for raising the samo when
the pressure is taken off by moving the stop handle in which case one end of the
strip of leather or wire first herein mentioned is connected by cord or otherwise to a
spiral spring attached to the slay sword or other convenient part of the loom.
The improved warp beam and appliances connected therewith are designed for the
purpose of allowing the warps on the beam to be wover close up to the healds, and
thus prevent loss and waste of "énds" and to dispense with the tying of the warp
bean, which is a tedious and uncertain operation by reason of the varying strength
of cords or strings employed.
'
According to my invention the warp bean rod is attached to the warp benin by
means of steel ribbons (preferably two) one of their ends being secured to the warp
beam, and a loop is formed in the fiee ends, through which loop, the warp beau
rod is passed and thereby securely held the steel ribbons being wound two, three, o
more times round the warp beam according to the distance between the latter and the
healds, and the warp beam rod is placed in the race of the beam as usual

According to this my said invention hinged to the hand rail of the loom is a flat-
strip or bar of wood 2 of section which extends from one end of the shuttle race to
the other, and at one end of the strip or bar of wood 2 is attached a cord or leather
strap 3 which passes over the top of the hand rail 1 or through a hole 4 formed near
the top of the same, and over a small grooved pulley 5. fixed to the back of the hand
rail 1. To the strip or bar of wood 2 is also secured a second cord or leather strap 6,*
or the end of the first strap 3 which is fixed to the bar of wood
so as to take the place of the part-marked 6 and this strap 6 is carried underneath the
may be prolonged,
hand rail 1 and over the grooved pulley 5, or over another grooved pulley 7 fixed at the
back of the hand rail 1. Both free end 8-9 of the strap or straps 3. 6 are connected
to cords or wires 10-10 the lower ends of the latter being attached to a strip of leather
or cord 11. which passes round the grooved guide pulley 12 carried on the bracket 13'
fixed to the front or side frame of the loom. The bracket 13 also carries a lever 14
free to rock on its fulcrum stud 15, and one end 16 of the lever 14 is attached to or
works through a eye or slot in the strap 11 and its other end is formed with a slot 17
in which is received one end of a lever 18 free to move on its fulcrum stud 19 fixed
to the loom frame, the other end of the lever 18 is formed with a slot 20 through,
which works a pin or stud 21 fixed to the lower part of the stop handle 22.
The action is as follows:-When the loom is standing or "knocked off" the strip
of wood or guard 2 is up, or turned back and the race is open (see Figs. 1 and 4) but
when the stop bandle 22 is moved to restart the loom the strip of wood or guard 2 is-
rawn down on its binge (see Figs. 2 and 3) by the stud 21 fixed on the stop handle 22.
nd working in the slot 20 one end of the lever 18 is raised and turning on its fulcrum
tud 19 the opposite end working through the slot 17 in the lever 14 is lowered
onsequently depressing one end of the lever 14 and the latter moving on its fulcruni,
tud 15 its end 16 is raised, and being attached to the strap 11 the latter is drawn up,
nd the portion of the strap 11 at the other side of the pulley 12 is by the same
ovement pulled down and by the connecting cords or wires 10. 10 the straps 3.6
re operated, the strap 3 being moving in an upward direction when the strap 6-is
rawn down the strap 11 cords or wire 10. 10 straps 3. 6 forming practically an
adless band from the shuttle guard 2 to and round the pulley 12 so that the action
the guard is positive when one end or cord is being drawn down the other, and
posite one is drawn up and vice versa and by the movement of the stop handle the
uard 2 is raised to the position shewn in Figs. 1 and 4 when the loom is stopped and
e race is open, but so soon as the stop handle 22 is moved to start the loom the
ard is brought down to the positions shewn by Figs. 2 and 3 and the strip or bar of

page_text: wood 2 being of
section pads against and fits closely to the hand rail 1 forming
a complete cover over the shuttle race and preventing the shuttle from flying out.
In the modified form of my invention which is illustrated on sheet 2 of the
accompanying drawings. The shuttle guard is composed of a flat strip or bar of.
metal 2 hinged-at-its-ends-2-2-to-the-handrail 1 and to one end of the shuttle 5
guard 2 is attached the strip of leather 3 which passes over the guide pulleys 5. 7 aud
its free end 8 is by wire or cord 10 attached to the strap 11 the other end of
which is secured to the end 16 of the lever 14. To the other end of the shuttlo
guard-2.is attached a strip of leather_or_cord_6″ which passes over the guide pulleys 5ª
and 7ª and its free end 9 is connected to the end of a spiral spring 23 fast to the slay-1
sword 26 or other convenient parts of the loom. In action it is similar to the herein-
before described device when the loom is in motion the guard 2 being drawn out or
turned on its hinge with a parallel and horizontal motion so as to cover the shuttle
race and prevent any possibility of the shuttle flying out (see Fig. 10) when the loom
is stopped the spiral spring 23 turns or draws the guard 2 on its hinge close into the
hand rail 1 and the race is open. (See Fig. 7)
It will be obvious that the apparatus described and illustrated by Figs. 1. 2. 3. 4
and 9 can be operated by spiral spring and one or a single strap 3 in which case the
shuttle guard will be raised in the manner described, and lowered and applied by
the spiral spring when the loom is started or vice versae that is to say the guard 2 will
be raised by the spiral spring and lowered by the strip 3 and its connections with the
stop handle 22.
The improved warp beam and appliances connected therewith (see Sheet 4) are
designed for the purpose of allowing the warps 27 on the beam 28 to be woven close
up to the healds 29 and consist in the employment of two strips, or bands of
metal 30, 30 preferably steel one of the ends 31, 31 being fixed to the warp beain 28
their other ends 32, 32 having loops 33, 33 formed on them and which loops receive
the warp beam rod 34 and securely hold the same. The warps being tied to the rod 34
or otherwise secured as ordinary. The steel ribbons or bands 30. 30 being wound
two three or more times round the bean 28, according to their length; and the
distance from the beam 28 to the healds 29, and the warp beam rod 34 is received
in the beam race 35 as ordinary, the steel ribbons 30. 30 being thin and soft
enough to admit of being pressed into the race 35 when the rod 34 is being placed
therein. By the use of the improved appliances I am enabled to utilize the "ends" of
the warps 27 close up to the healds 28 without any danger of shipping or breaking of
the bands, or ribbons, thus a great saving of the ends of warp is effected.
Having now particularly described and ascertained the nature of my said Inven
tion and in what manner the same is to be performed, I declare that what ]
claim is
1. A folding shuttle guard consisting of a hinged strip, or bar of wood, or meta
such as 2 connections 10, 10 passing over pulleys the whole being operated through
the intervention of levers such as 14, 18 stop handle 22 all the parts in combination
and substantially as illustrated by Drawings annexed and herein fully described.
2. A shuttle guard such as 2 having horizontal and parallel motion imparted theret
through the agency of the cord, guide pulleys and spiral spring, levers, and sto
bandles, all the parts in combination substantially as illustrated by Figs. 5. 6. 7
and 10 and as herein described.
3. In a warp beam the use of bands or ribbons such as 30, 30 loops 32. 32 an
rod 34 to which the ends of the warp are attached for purpose as herein set forth an
substantially as such apparatus is illustrated by drawings annexed.
