PROVISIONAL SPECIFICATION.
Improvements in Circular Box Looms.
I, ARTHUR SOWDEN, of the firm of David Sowden and Sons, of Sowden's
Loom Works, Shipley, in the County of York, Loom Maker, do hereby declare
the nature of this invention to be as follows:-
This invention relates to circular box looms, and the object is, by utilizing the
momentum and impact of the incoming shuttle, and its picker, upon the picker
buffer or upon the check strap to operate devices which will admit of the use of
"fast reeds" in connection with such looms.
According to this my invention I connect with the buffer nearest the outer end
of the shuttle box, a rod, or strap attached to and controlling an interposing finger
or a rod lever and slide piece employed in connection with a finger on the stop
rod, so that when the shuttle enters the box properly it presses forwards the picker
in that box and forces the latter against the buffer connected with the rod or
check strap referred to and thereby draws the interposing part clear of the finger
on the stop rod, but should a trap occur or from any cause the shuttle fail to enter
the box, there being.no impact or pressure on the buffer, the finger or interposing
part is not drawn clear of the finger on the stop rod and as the latter is not
operated the "stop finger" comes in contact with the " frog" and the motion of
the loom is arrested, before the warp composing the shed can be damaged by the
shuttle trapped.
The interposing part may consist as described of a finger a slide piece or a anti-
friction runner working on inclines. A return spiral spring is employed for insuring
the parts returning to their normal position.
For some class of circular boxes I may employ a "swell" which is applied to
the side of each cell there being a curved finger from the stop rod to the back of
the swell and on the crank shaft is a tappet which at each revolution acts upon a
lever and through the latter in part lifts the stop finger and cases the pressure on
the swell for the outgoing pick.

Improvements in Circular Box Looms.
I, ARTHUR SOWDEN, of the firm of David Sowden and Sons, of Sowden's
Loom Works, Shipley, in the County of York, Loom Maker, 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 circular box looms, and the object is, by utilizing the
momentum and impact of the incoming shuttle, and its picker, upon the picker
buffer or upon the check strap to operate devices which will admit of the use of
"fast reeds" in connection with such looms.
According to this my invention I connect with the buffer or check strap nearest
the outer end of the shuttle box a rod, or strap attached to and controlling an
interposing finger or a rod L lever and slide piece employed in connection with a
finger on the stop rod, so that when the shuttle enters the box properly it presses
forwards the picker in that box and forces the latter against the buffer connected
with the rod or check strap referred to and thereby draws the interposing part
гл.

stop rod is raised above, and clear of the "frog" but should a trap occur or from
any cause the shuttle fail to enter the box there being no impact or pressure on the
buffer or check strap the finger or interposing part does not draw clear the finger
on the stop rod, and the latter not being operated the stop finger comes in contact
with the frog" and the motion of the loom is arrested, before the warp composing
the shed can be damaged or the shuttle trapped.
The interposing part may consist as described of a finger, a slide piece or a anti-
friction runner working on inclines. A return spiral spring is employed for insuring
the parts returning to their normal position.

For some class of circular boxes I may employ a
"swell which is applied to
the side of each cell there being a curved finger from the stop rod to the back of
the swell and on the crank shaft is a tappet which at each revolution acts upon a
lever and through the latter in part lifts the stop finger and eases the pressure on
the swell for the outgoing pick.
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 view of a part of a loom having my improved "fast reed"
motion applied to the ordinary check strap and shewing the parts in the position
assumed when the shuttle is crossing the " race or has failed to box.
Fig. 2 is an end sectional view of Fig. 1.
"
Fig. 3 is a front view of my improved "fast reed" motion as applied to the
buffer.
Figs. 4, 5 and 6 are front elevations of forms of interposing finger or levers.
Fig. 5 is an end elevation of a part of Fig. 5.
Fig. 7 is a front elevation of a pair of mitre, or bevel wheels for operating the
"fast reed" motion.
Fig. 8 is a front elevation of rack and pinion for operating the motion.
Fig. 9 is a front elevation of slide piece and inclines for operating the "fast
reed" in motion.
Fig. 10 is an end view of Fig. 8.
Fig. 11 is a side elevation of part of a shuttle box having my improved appliances
for removing the pressure from the "swell" applied thereto.
Fig. 12 shews the same appliance as used in connection with a circular
shuttle box.
The remaining figs. on Sheet 3 are details drawn detached in order to more
clearly illustrate their construction.
According to this my invention and referring, to the "fast reed" motion I
connect with the buffer A. by rod or strap 1 (see Figs. 3, 4, 5, 54, 6, 7 and 8) an
interposing finger or lever 2, or such finger or lever 2 is connected to the
ordinary check strap 1ª see Figs. 1, 2, 9 and 10, the said finger or lever 2 being
carried on a fulcrum stud or pin 3 fixed to the slay sword 4 or to the front of
race 5 or other going part of the loom. On the finger 2 I mount a cross piece or
lever 6 (or the lower arm 6, of the lever is used in lieu of the cross piece)
and on the stop rod 7 of the loom I mount a finger 8 which carries an anti-
friction runner (see Figs. 1, 2, 3, 4 and 5) the action of which is as follows:-
When the shuttle enters the box 10 and is properly "boxed it presses forward
the picker 11 in that box and the picker II being forced against the buffer A
or against the check strap 1" (see Fig. 1) draws or moves the buffer A and
strap or check strap 1 along with it and so turns or moves the interposing finger
or lever 2 on its fulcrum 3 and lifting the cross piece, or lower arm 6 of
the finger or lever 2 which carries with it the runner 9 and curved finger 8 the
latter giving a part turn or revolution to the stop rod 7 and the latter thereby
raises the "stop finger" 12 above and clear of the frog 13 of the loom the stop
finger 12 assuming the position shewn by dotted lines in Fig. 2.

But should the shuttle fail to "box then no motion is given to the buffer A

page_text: rod or strap 1 or ordinary check strap 1, and the interposing parts connected
therewith, and the stop rod 7 and finger 12 not receiving any motion the "stop
finger" 12 will at the forward movement of the slay of the loom come in contact
with the "frog" 13 (see Fig. 2) and the motion of the loom is arrested and
stopped before the "beat up and consequently before the warp composing the
shed can be damaged or the shuttle become "trapped" therein.
In Fig. 7 the lower part of the finger or lever 2 is cast to or forms a mitre
wheel 14 which gears with a like wheel 15 on the stop rod 7 the action being
similar to that above described when the shuttle is "boxed" the mitre wheel 14
is partly revolved on its stud 3 thus giving a partial rotation to the wheel 15
and stop rod 7 thereby turning or raising the stop finger 12 above and clear of
the frog 13.
Fig. 8 shews a rack 14 gearing with and driving a pinion 15 and operating in
the manner herein above described.
When a buffer A and rod or strap 1 are employed a return spring 16 brings the
parts to the normal position when the shuttle is expelled from the box, and the
tension removed from the strap 1 but where the ordinary check strap 1ª is employed
no spring is required as the entrance to the shuttle into one of the boxes brings
the interposing parts at the opposite end of the loom into their normal position
and vice versa.
In Figs. 9 and 10 the ordinary check strap 1ª is divided and each end is fixed
to a slide bar 17 carried in brackets 18 fixed at or near the centre of the race 5.
The slide bar carries two inclined faces 19, 19 one or other of which when the
shuttle is "boxed" is drawn by the ordinary check strap 1° under the runner 9
and by the finger 8 the stop rod 7 is turned in its bearings, and the "
clears the "frog" of the loom, no return spring being employed.
stop finger"
Referring now to the device for removing the pressure from the "swell" 20 of
the shuttle box (see Sheet 3 of the drawings) which is employed in connection with
a fixed or stationary shuttle box (see Fig. 11) or to each cell 10 of a circular
shuttle box (see Fig. 12) I employ a curved finger 22 securely mounted on the stop
rod 7 one end of such finger 22 pressing against the swell 20 and near the other or
stop finger end of the finger 22 is mounted an antifriction runner 23 which rests
on a lever 24 mounted on a fulcrum stud 25, and the opposite end of the lever 24
is depressed by a tappet 26 at each revolution of the crank shaft 27 on which
the tappet 26 is mounted. The finger 22 is pressed against the swell 20 by a spiral
spring 20 fixed to the slay sword 4 and to the finger 22, or by a blade spring as
shewn at 21º.
This depressing of one end 28 of the lever 24 raises the opposite end and in
part lifts the curved finger 22 turning the latter on the "stop rod "7 and so
removing the end of the finger 22 from the swell 20 easing the pressure of the
latter on the shuttle for the outgoing “pick.”
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 check or strap 1 (or its equivalent) finger L, lever 2, cross piece or arm 6
runner 9 curved finger 8 stop rod 7 and stop finger 12 all in combination as and for
the purpose herein described and substantially as illustrated by Figs. 1 and 2 of
the accompanying drawings.
2. The buffer A connecting rod or strap 1, finger or L lever 2, cross piece or
arm 6, runner 9, curved finger 8, stop rod 7, and stop finger 12 all in combination
