I FRANK LEEMING, of the firm of John Leeming and Son, North Vale Works,
Bradford, in the County of York Machine Maker, do hereby declare the nature
of my said invention for “IMPROVEMENTS IN Äpparatus for operatING SHUTTLE
BOXES, FOR REGULATING THE PICKING, AND FOR ENSURING THE BOTTOM OF THE
CELL BEING LINABLE WITH THE RACE OF LOOMS to be as follows:---
"
This invention consists, of an improved construction, and combination, of
segment peg, and star wheels, and compound levers, for operating multiple shuttle
boxes, of looms for weaving, and to an improved link and slot, or cam plate,
combined with, and for guiding and controlling the movement of the shuttle box
rod, so as to ensure the bottom of each shuttle cell being on the same plane, or
level with the shuttles race.
By gear wheels, from the crank shaft, is operated a cross shaft, on which are
two peg wheels, these wheels are made in two parts, one part by the inner boss,
being fast on the shaft, the other part which carries the pegs, being capable of
sliding on its shaft by a cam or inclined surface formed on its boss. A star wheel
driven by the peg wheel, by means of rod or link, is connected with a lever, having
its fulcrum, at the end of a second lever, the latter has an independant and
stationary fulcrum, and is actuated by rod or link, and star wheel, operated by a
peg wheel, as described in relation to the first mentioned lover, the peg portion of
the wheel is caused to slide upon its shaft, and key, by means of a small anti
friction pulley, carried by fingers, controlled by the peg or pattern mechanism.
The action is as follows:-
When there is no peg, to lift the finger and antifriction pulley, out of the cam,
formed in the boss, of the peg segment of the wheel, the incline draws the pegged
portion of the wheel inwards, and clear of the star wheel, thus bringing the flanged
portion into line with a cavity of the star wheel, and no change of box will occur,
but when a peg lifts the runner out of the cam way of the boss, a spring will draw
the peg part, into position, for engaging with the star wheel, and moves the latter
half a revolution, and by the connecting rod, operates a lever, and box rod, changing
T "

page_text: the shuttle cell, and locking the box, by the rim and cavity of the star wheel in
position, until another box is required. Where a change from box 1 to 4, is
required, both peg and star wheels, will be operated, so as to simultaneously move
both the levers, theroby ensuring the full amount of motion. The end of the
compound lever, is by link and stud, connected to the foot of the box rod, the
stud being passed through an inclined slot, or angled plate, fixed to the end frame
of the loom, so that as the lever raises the box rod, the stud connected therewith,
will move in this slot, so as to control and guide the angle or line of motion of the
box rod, ensuring the bottom of the cell, being linable with the shuttles race.
When the pattern being woven, requires eight shuttles, there will be three star,
and peg wheels, and three levers employed.

I FRANK LEEMINO, of the firm of John Leeming and Son, North Vale Works,
Bradford, in the County of York, Machine Maker, do hereby declare the nature
of my said invention for "IMPROVEMENTS IN APPARATUS FOR OPERATING SHUTTLE
BOXES, FOR REGULATING THE PICKING AND FOR ENSURING THE BOTTOM OF THE
CELL BEING LINABLE WITH THE RACE, OF LOOMS" and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:-
This invention consists, of an improved. construction, and combination of
segment, peg, and star wheels, and compound levers, for operating multiple shuttle
boxes, of looms, for weaving, and also relates to an improved link and slot, or cam
plate, combined with and for guiding and controlling the movement of the shuttle
box rod, so as to ensure the bottom of each shuttle cell being on the same plane, or
level, with the shuttles race.
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
forming a part of this specification in which:
-
Fig. 1 is an end elevation of part of a loom having my improvements applied.
Fig. 2 is an enlarged plan of Fig. 1.
Figs. 3, 4, 5 and 6 are details.
Fig. 7 is a section of Fig. 6.
By gear wheels 1, 1, from the crank shaft 2, is operated a cross shaft 3, on which
are two peg wheels 4, 5, these wheels are made in two parts 6, 7, one part 6 by the
boss 8 being fast on the shaft 3, the other part 7, which carries the pegs 9 being
capable of sliding on its shaft 3 by a cam or inclined surface 10, formed on its
boss 11, a star wheel 12 driven by the peg wheel 4, by means of rod or link 14, is
connected with a lever 15, having its fulcrum 16, at the end of a second lever 18,
the latter has an independent and stationary fulcrum 19, and is actuated by rod or
link 20, and star wheel 21, operated by a peg wheel 5, as described in relation to
the first mentioned lever 15, the peg portion of the wheel is caused to slide upon
its shaft 3, and key, by means of a small antifriction pulley 23, carried by fingers
or levers 24, controlled by the peg or pattern mechanism 25.
The action is as follows:-
When there is no peg 25 to bring the antifriction pulley 23 into the cam
surface 10 formed in the boss 11 of the peg segment wheels 4, 5, the spiral
springs 26 force back the peg segment wheels 4, 5, clear of the star wheels 12, 21,
the flanged portion of the wheels 6, 7, then engages in the cavity 27 of the star
wheels 12, 21, locking the same, and no change of box will occur. But when a
peg 25 brings the antifriction pulley 23, into the cam 10 formed in the boss 11 of
the peg segment wheels 4, 5, the antifriction pulley forces the peg portion of the
segment wheel 4 into position for engaging with the star wheel 12, and moves the
-

page_text: latter half a revolution, and by the connecting rods 14, operates the lever 18, and
box rod 29, changing the shuttle cell and locking the box by the rim or flanged
portion of the wheel 6 and cavity 27 of the star wheel 12 in position until another
box is required.
Where a change from A to B is required, both peg wheels 4, 5, and star
wheels 12, 21, will be operated, so as to simultaneously move both the levers
thereby ensuring the full amount of motion. The end of the lever 15, is by link
and stud 28, connected to the foot of the box rod 29, the stud 31 being passed
through an inclined alot or angled plate 30, fixed to the end frame of the loom, so
that as the lever 15 raises the box rod 29, the stud 31 connected therewith will
move in this slot 30, so as to control and guide the angle or line of motion of the
box rod, ensuring the bottom of the cell being linable with the shuttles race.
When the pattern being woven requires eight shuttles, there will be three star,
and peg wheels, and three levers employed.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
}
1. The peg and star wheel mechanism controlled by pattern mechanism such
as 25, the peg and star wheel mechanism operating the compound levers 15, 18,
and box rod 29, and shuttle boxes, in combination, and as herein described, and
substantially as illustrated by drawings annexed.
2. The link 28 combined with a lever such as 15, and a slotted plate 30 for
operating and guiding the box rod 29 as herein described and illustrated by
drawings.
