Improvements in Looms for Weaving.
1, CHARLES THOMPSON, of 2 St. James Place, Otley Road, Baildon, in the
County of York, Mill Furnisher, do hereby declare the nature of this invention to.
be as follows:-
:-
1
This invention relates to improvements in looms for weaving, and consists.:-
Firstly-Of improvements in shuttle checking appliances, whereby I dispense
with the check strap, "swell and finger of the shuttle box, and 'the shuttle checking
appliance also operates the "check end on the stop rod.
"
Secondly-To improvements in the method of and means employed for connecting
picking straps to the picking sticks designed to ensure greater durability of the
straps, and a direct action on the picker, so that the latter is effective in its action,
and subject to less wear and tear.
:-
Thirdly To improvements in "fast" and "loose" reed motions consisting of
appliances designed for locking the reed in position whilst the shuttle is crossing
the race, dispensing with the bow spring and bowl heretofore employed, and
simplifying, and reducing the cost of production, of the motion.
.
According to this invention, and referring to the shuttle checking appliances,
I employ a finger or lever pivoted to the front of the shuttle box, with its free
end connected to a loop of leather passing, around the picker spindle. The
lower end of the lever or finger is by rod, or wire and cord, passing over. a
guide pulley connected to the stop rod tonge, which is held down by a spiral'
spring. When the shuttle enters the box, the picker is forced 'thereby against
the loop of leather, and the latter draws the finger or lever outwards, and the
wire, or rod and cord, pull the stop rod tonge upwards, and clear of the frog,
so that the slay is at liberty to complete the "beat up.'
If 'the shuttle fails to
box properly, the stop rod tonge remains down, and at the "beat up." comes
in contact with the frog, which prevents a further forward movement.
"""
The improvements in picking straps are as follows:-I' employ a loop of
leather, the outer surface of which is covered with thin sheet metal, and the
inside is provided with a bush of leather. The end of the picking stick is
passed through the bushed end of the loop, and on each side of the loop, and on
the stick placed a leather flange, the whole being held by a through pin. The
picking strap is connected to the loop by being passed through a hole therein, then
over a peg, and again through the same hole, and. then through a second hole, so
that no holes are formed in this end of the picking strap. In the loop.between
the picking strap and the outer end of the loop, I place a peg. which prevents the
loop turning. The strap is connected 'to. the picker by means of a leather thong
passed round the top of the picker and strap, and then through a hole in this end
of the strap. The first part to become. worn is the leather bush, which can readily;
be replaced with scrap leather.
The improved fast reed motion comprises a bracket fixed to the front of the.
slay, and in this bracket is pivoted. a lever held in one position by a spring. On,
the stop rod is a finger, one end of which comes under the end of the lever, and is
thereby held, and the reed is fast when the slay is moving backwards. At the
forward movement of the slay, 'one end of the lever comes in contact with a
t

clear of the finger, so that the reed is loose in its cap.

Improvements in Looms for Weaving.
I, CHARLES THOMPSON, late of 2 St. James' Place, Otley Road, Baildon, in
the County of York, Mill Furnisher, now of 41 Low Baildon, Baildon aforesaid,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement —
This invention relates to improvements in looms for weaving, and consists,
Firstly. Of improvements in shuttle checking appliances, whereby I dispense
with the check strap, swell and finger of the shuttle box, and the shuttle checking
appliance also operates the "check end on the stop rod.
"
Secondly:-To improvements in the method of and means employed for connecting
picking straps to the picking sticks designed to ensure greater durability of the
straps, and a direct action on the picker, so that the latter is effective in its action,
and subject to less wear and tear.
Thirdly To improvements in "fast" and loose reed motions consisting of
appliances designed for locking the reed in position whilst the shuttle is crossing
the race, dispensing with the bow spring and bowl heretofore employed, and
simplifying, and reducing the cost of production of the motion.
Such being the nature and object of my said invention, the following is a com-
plete description of same, reference being had to the accompanying drawings, in
which
Fig. 1 is a front elevation of part of a shuttle box having the improved shuttle
checking appliances applied thereto."
Fig. 2 is an end elevation, partly in section of Fig. 1.
Fig. 3 is an elevation of the end of a picking stick with the picking strap attached
thereto, according to this invention.
Fig. 4 is an elevation of part of a picking strap such as shewn by Fig. 3, but in
this case the strap consists of two parts or lengths.
Fig. 5 is a 'view shewing the method of attaching the picking strap to the
picker.
Fig. 6 is a plan view of the improved appliances for locking and releasing the
reed.
Fig. 7 is an end sectional elevation of Fig. 6.
Fig. 8 is a detail.
According to this invention, and referring to the shuttle checking appliances, and
to Figs. 1 and 2 of the accompanying drawings, I employ a finger or lever 1 pivoted
at 2 to the front of the shuttle box 3 with its free end cranked towards the picker
spindle 4, and connected to the cranked end is a loop of leather or disc of buffalo
hide 5 passing around or spanning the picker spindle 4. The lower end of the
lever or finger 1 is by rod, or wire and cord 6, passing over a guide pulley or boss 7
of the lever or finger 1, connected to the ordinary stop rod tonge 8, or to another
finger 9 on the stop rod 10, which is held down by a spiral spring 11 as ordinary.
When the shuttle enters the box 3, the picker 12 is forced thereby against the loop
of leather or buffalo hide 5, and the latter forces the finger or lever 1 outwards,
and the wire or rod and cord 6, pull the finger 9 turning the stop rod 10, and raising
the stop rod tonge upwards and clear of the ordinary frog, so that the slay is at
- 1

page_text: liberty to complete the "beat up.” If the shuttle fails to box properly, the stop
rod tonge remains down, and at the "beat up," comes in contact with the frog,
which prevents a further forward movement.
The improvements in picking straps (see Sheet 3) are as follows:-I employ a
loop of leather 1, the outer surface of which is covered with thin sheet metal 2, and
the inside is provided with a bush of leather 3. The end of the picking stick 4 is.
passed through the bushed end of the loop 1, and on each side of the loop 1 and on
the stick 4 are placed leather flanges or washers 5, the whole being held by a through,
pin 6. The end of the picking strap 7 may itself form the loop 1 and be in one-
piece, or the loop 1 may form a separate part (see Fig. 4) and the strap 7 be-
connected thereto by its free end being passed through a slit 8 in the loop,' then
carried round the front of the loop 1, and in at the back through the same hole or
slit 8 to the front.. By this method of securing the strap 7 to the loop 1, it is not.
necessary to have any holes in the strap, as the greater the pull on the strap, the
tighter the knot or fastening becomes.
In the loop 1 between the picking strap 7 and the outer end of the loop, I place
a peg or strip of leather 9, which prevents the loop tearing at the bottom of the
slit 8. The strap 7 is connected to the picker 10 by passing the end of the strap 7,.
(or a thong of leather attached to the strap 7) through a loose loop 11, then passing
the end of same strap round the top of the picker 10, and then again through the
hole in the loop 11, after which a pin 12 is passed through the end of the strap 7 or
thong. In the loop formed by the strap 7 passing round the top of the picker 10,
I preferably place a bush of leather or metal 13. The first part of the loop 1 to
become worn is the leather bush 3 or the bush 13, which can readily be replaced with.
scrap leather or metal.
•
The improved fast and loose reed motion (see Sheet 4) comprises a bracket 1
fixed to the front of the race or slay 2, and in this bracket is pivoted a lever 3, held
in oue position by a spring 4. On the stop rod 5 is a finger 6, one end 6" of which
comes under the end of the lever 3, and is thereby held, and the reed is fast when
the slay is moving backwards. At the forward movement of the slay, one end 8 of*
the lever 3 comes in contact with a projection 7 on a fixed part of the loom, such
as the front rail, the lever 3 is turned on its pin, and the opposite, end of the lever
is moved clear of the finger 6, so that the reed 12 is loose in its cap. In Fig. 6 the
reed case 10 is loose, the lever 3 not being in contact with the finger 6 as it is shewn
by Fig. 7 where the reed 12 is fast.
The finger 6 is preferably made double acting, by carrying out from near the
end 6ª a second cranked finger 6b, with an intervening space between the two. By
this means the motion is made to lock the reed fast both at the backward and the
forward motion of the slay, as follows:-When the slay moves backwards, the
spring 4 pulls and holds the lever 3 above and in contact with the finger 6, so that
the latter cannot turn on the stop rod, and the reed 12 is fast while the shuttle is
crossing the race. When the slay moves forward, the end 8 of the lever 3 comes
in contact with the projection 7 on the breast beam, and is thereby turned on its pin,.
moving its other end clear of the finger 6, and the finger 6 can then turn on the
stop rod, and the reed 12 is loose. When the shuttle is "boxed," and just before
the "beat up," the lever 3 is moved still further by the continued and increased
pressure against the projection 7 until the other end is above and in contact with
the end 6 of the finger 6, so that the reed is again locked fast just previous to the
"beat up."
As long as the lever 3 is between the ends 6, 6b of the finger 6, the reed 12 is
loose, ie, if the shuttle is trapped whilst crossing the race, the reed case 10 will
be forced backwards, the finger 6 and stop rod 5 will make a partial turn, and the
reed is free to swing in its ca. To compensate for wear and tear of the fingers 6", 6",
and also the end of the lever 3, and to allow of the parts being readily adjusted
to suit different thicknesses of reed, I employ caps or covers 13, of steel (see
Fig. 8) which as the ends of the fingers 6, 6b or levers 3, become worn, or when
a thinner reed is employed, are placed on the ends of the said fingers, or on the

page_text: underside of the lever 3, and fixed thereto by screws. When necessary, a strip
of leather can be placed between the steel cap or cover 13, and the finger or lever,
to regulate the thickness.
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. I
claim is :-
(1) The cranked finger or lever 1 with the. loop or disc of leather or buffalo
hide 5; picker spindle 4, strap, rod, cord, or wire 6; stop rod tonge or finger 9,
