PROVISIONAL SPECIFICATION.
Improvements in Looms for Weaving.
I, THOMAS SINGLETON of Bank Top Works, Darwen in the County of
Lancaster, Machinist do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in looms for weaving and consists :-
Firstly. Of improvements in what are known as fast and loose reed motions of
looms for weaving the object being to ensure the reed being fast and rigid at the
beat up of the weft and at all times excepting when the shuttle fails to box
properly whereou the reed is loose and no damage is done to the yarn and the
improved apparatus will when the reed is loose stop the loom.
Secondly. To improvements in the swells of shuttle boxes the object being to
provide a swell which will effectively ease the momentum of the shuttle without
there being any possibility of binding or locking the shuttle.
Thirdly. To improved picker preserver by use of which I am enabled to
dispense with the picker preserver strap as heretofore employed and to construct a
more effacacious and cheaper appliance.
According to this invention the reed case is secured to a hollow rod or tube
carried in bearings beneath the slay and to the hollow tube is fixed a finger on the
end of which is an adjustable pin or stud. Above the pin or stud is a catch piece
carried on a short shaft fixed to the slay and the other end of this shaft carries a
loose catch or pawl in which is a stud or pin the end of which is received in a slot
formed in the ordinary finger which operated by the swell of either of the shuttle
boxes in the ordinary manner. The finger stop rod which carries the ordinary
finger is carried in the hollow rod or tube above mentioned. A spiral spring
attached to the short shaft and to any point of the slay ensures the catch piece
being held in contact with the pin or stud on the finger fixed to the hollow tube.
Below the loose catch or pawl is a notched bracket carried on the end of a blade
spring.
→
When the loom is in motion and the shuttle boxes correctly, the reed is fast, but
should the shuttle fail to box properly then the finger does not act on the loose
pawl or catch and the latter at the forward or beat up motion of the slay comes in
contact with the notch on the end of the blade spring, the catch or pawl is forced
backwards and by a short connection a part turn is given the short shaft so that
the catch piece thereon is moved clear of and liberates the pin in the finger fixed to
the hollow rod or tube and the latter is free to turn in its bearings and the reed is
loose..
As the slay continues to move a little more forward the blade spring after
overcoming the resistance of the spiral spring above mentioned is also moved and
comes in contact with an adjustable piece fixed to the spring handle and the latter
is moved out of its holding notch the loom is stopped.
The parts are set in their working position by the finger on the hollow rod
or tube being pressed down by the operator, under the holding catch on the
short shaft.
According to this I employ a swell made of cast or mallable iron or of a strip of
steel bent to the required form and catch end of the swell rests on the back of the
shuttle box. At the back of the shuttle box is fixed a bracket in which is a bolt or
stud carrying a blade spring so that one end of the latter rests and bears on each
end of the swell and thus the pressure of the spring is equal at each end of
the swell.
I employ a strip of stout felt or other woven fabric which is wrapped round the

page_text: picker spindle and enclosed in a tube preferably metal and open at both ends so that
the felt or other material protrudes beyond the tube and forms an effectual picker
preserver. A small piece of leather is preferably placed on the spindle as the face
of the preserver.

COMPLETE SPECIFICATION.
Improvements in Looms. for Weaving.
-I; THOMAS SINGLETON, of Bank Top Works Darwen, in-the-County of
Lancaster, Machinist, 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 :-
ส
This invention relates to improvements in looms for weaving and consists :-
Firstly-Of improvements in what are known as fast and loose reed motions of
looms for weaving, the object being to ensure the reed being fast and rigid at the
beat up of the weft, and at all times excepting when the shuttle fails to box
properly, whereon the reed is loose, and no damage is done to the yarn, and the
improved apparatus will when the reed is loose, stop the loom by knocking off the
stop handle.
Secondly. To improvements in the swells of shuttle boxes, the object being to
provide a swell which will effectively ease the momentum of the shuttle without
there being any possibility of binding or locking the shuttle, and the resisting
pressure of which can readily be adjusted as desired.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the accompanying drawings,
in which
Fig. 1 is a front elevation of part of a loom having the improved fast and loose
reed motion applied thereto.
Fig. 2 is an end sectional elevation of the improved fast and loose reed motion
drawn to a slightly larger scale than Fig. 1 shewing the slay back, i.e. when the
shed is open.
Fig. 3 is a similar view to Fig. 2, but drawn to an enlarged scale, and the slay is
shewn at the "beat up," and the several parts in the positions assumed when the
shuttle has failed to box.
Fig. 4 is a back elevation of a shuttle box back having the improved "swell
applied thereto.
Fig. 5 is a front elevation of Fig. 3.
Fig. 6 is a sectional plan view on line A. B. of Fig. 4.
According to this invention, the reed case-1-is secured by brackets or arms 2,
to a hollow rod or tube 3, carried in bearings 4 fixed beneath the slay 5, and to
the hollow tube 3 is fixed a finger 6 on the end of which is an adjustable pin or
stud 7. Above the pin or stud 7 is a catch piece 8, carried on a short shaft 9
fixed by brackets 10 to the slay 5, and on the other end of this shaft 9. is a
small crank 11, which carries a loose catch or pawl 12, in which is a stud or
pin 13, the end of which is received in a slot 14 formed in the ordinary finger 15,
which is operated by the swell 16 of either of the shuttle boxes 17 in the ordinary
manner. The stop rod 19 which carries the ordinary finger 15, is carried in
the hollow rod or tube 3 above mentioned. A spiral spring 20 attached to a
boss 18 on the short shaft 9 and to any point of the slay or slay sword 21, ensures
the catch piece 8 being held forward aud in contact with the pin or stud 7 on the
finger 6 fixed to the hollow tube 3. Below the loose catch or pawl 12 is a notched
bracket 13 carried on the end of a blade spring 14.
The action is as follows-When the loom is in motion, and the shuttle boxes

page_text: correctly, the reed 22 is fast; but should the shuttle fail to box properly, then the
swell 16 is not operated, and the finger 15 does not act on the loose pawl or
catch 12, and the latter at the forward or "beat up" motion of the slay, comes in
contact with the notch 23 on the end of the blade spring 14ª (see Fig. 3), the
catch or pawl 12 is forced backwards, and by the short crank or connection 11,
the resistance of the spring 20 is overcome, a partial turn is given the short
shaft 9, and the catch piece 8 fixed thereon is moved clear of and liberates
the pin 7, and the finger 6 fixed to the hollow rod or tube 3, and the latter is
free to turn in its bearings, and the reed case and reed are loose (see Fig. 3).
As the slay 5 continues to move a little more forward, the blade spring 14" after
overcoming the resistance of the spiral spring 20, is also moved and comes in
contact with an adjustable piece 24 fixed to the spring handle 25, and the latter is
moved out of its holding notch, or "knocked off," and the loom is stopped.
The parts are set in their working or normal position by the finger 6 on the
hollow rod or tube 3 being pressed down by the operator under the holding catch 8
on the short shaft 9.
The end 25 of the finger 15 fast on the stop rod 19 may be continued until its
end 25* rests against the back of the swell 16, or a second finger 26 fast on the
stop rod 19, may be employed for giving the requisite partial turn to the rod 19
when the shuttle is boxed correctly, and the catch or pawl 12 is required to clear
the notch 13.
Referring now to the improved swell and to Sheet 4 of the drawings. The
swell 1 is made of cast or mallable iron, or of a strip of steel bent to the required
form (see Fig. 6), and each end of the swell 1 rests on the back 2 of the shuttle
box. At the back 2 of the shuttle box is fixed a bracket 3, in which is a bolt or
stud 4 carrying a blade spring 5, so that the ends 6. 6 of the latter rest and bear on
each end 7 of the swell i, and thus the pressure of the spring 5 is equal at each
end of the swell 1.
Each end 6 of the spring 5 is recessed (see Figs. 4 and 6) so that the ends do
not slip or work off the swell 1.
By making a groove or corrugation 8 across the spring 5, the adjusting nut 9
is prevented from turning round when once set.
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 general construction, arrangement and combination of parts comprising
the fast and loose reed motion, as and for the purpose herein described, and
substantially as illustrated by Figs. 1. 2. and 3 of the accompanying drawings.
(2.) The hollow rod or tube 3, finger 6, pin 7, catch piece 8 carried on the short
shaft 9, on which is the crank 11 and pawl 12 operated by finger 15 from the stop
rod 19, all in combination, and as and for the purpose herein described, and
substantially as illustrated by Fig. 1 of the accompanying drawings.
(3.) The stop rod 19, finger 15, catch or pawl 12; notched bracket 13, blade
spring 14, and stop handle 25 with the adjustable piece 24, all in combination, as
and for the purpose herein described, and substantially as illustrated by Figs. 1. 2.
and 3 of the annexed drawings.
(4.) In shuttle boxes of looms for weaving, a swell consisting of a bent strip of
metal, the pressure on which is applied by a blade spring held in position by a mut
and bolt, as herein described and substantially as illustrated by Sheet 4 of the
accompanying drawings.
