PROVISIONAL SPECIFICATION.
Improvements in Drop-box Looms.
I FREDERICK HERBERT GOSLING of 70 George Jane Bredbury in the county of
Chester, Overlooker do hereby declare the nature of this invention to be as follows:-
This invention relates to check looms, and especially to the drop box motion known
Wright Shaw's" and consists in an improved arrangement for working the drop
as
boxes.
دو
I mount the pattern cylinder on an angle lever on the loom side at a convenient
height from the floor so as to allow the pattern chain to depend therefrom and also
to be more easy of access.
To the three pattern needles are connected to each a right angle lever, to the inside
and outside right angle levers are two rods connected at their lower parts to opposite
ends of a T bracket which T bracket is connected to a horizontal rod which gears the
bootjack.
To the angle lever on the middle pattern needle is attached a rod connected at its
lower extremity to a fork mounted on a suitable bracket, for throwing the double lift
cam into gear.
In place of the ordinary rack for raising or lowering the drop boxes I employ one
with slots cut in it, the distances of the slots apart being deterinined by the depth of
he drop boxes.
I dispense with the spring hammer for locking the drop boxes, the spring bracket
for holding the rack into gear, and the divided disc on the inside of the star wheel,
that the spring hammer locks into, and employ in their place a weighted lever, an end
of which presses the rack into gear, and also locks the drop boxes by binding in the
slots on the rack.
In my improvements the teeth in the bootjack, the two gears of the star wheel, and
in the rack are of the same number per inch not of two sizes as in the Wright Shaw
loom, my improvements not requiring the necessity of setting the drop boxes each
time they become unlocked.
As before mentioned the pattern cylinder is placed at a convenient height from the
floor and mounted on an angle lever, to the other end of the angle lever is suspended
a rod, carrying at its lower extremity a weight or spring, to this rod also is attached
a bowl working over a cam on the tappet or lower shaft of the loom by which cam the
pattern cylinder receives its movement.
To not allow the pattern cylinder to operate on the pattern needles in the event of
the weft breaking &c., I mount a rod in suitable brackets under the breast beam, one
end being connected to the pattern setting-on rod, and the other end being connected
to one end a a swivel lever, the other end of the swivel lever going underneath the
angle lever carrying the pattern cylinder, when the weft is broken thus preventing
the angle lever from traverseing its complete distance.

1 FREDERICK HERBERT GOSLING of George Lane Bredbury, in the county of
Chester, Overlooker 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 check looms, and especially to the drop box motion known

page_text: The object of my present invention is to simplify, and rearrange the mechanism for
working the drop boxes.
Fig. 1 in the annexed drawing is an elevation.
Fig. 2 a plan..
Fig. 3 a sectional plan through A. B. on Fig. 1, and
Figs. 4, 5, and 6, are detached views hereaffer described.
1 mount the pattern cylinder 7, on an angle lever 8, a stud 9, attached to the loom
side 10. carries the angle lever 8, at a convenient height from the floor, (preferably in
the position shown on Fig. 1).
The pattern needles 11, 12, and 13, (see Figs. 1 and 2) are placed in a more con-
venient position, each pattern needle being connected to one of the right angle
levers 14, 15, or 16, working on the stud 1.7.
When the pattern cards on the pattern cylinder 7, hereafter more particularly
described, actuate the pattern needles 11, or 13, the horizontal ends of the right angle
levers 14, or 16, will be raised, and thereby lift the upright rods 18, or 19, which rods
are connected at their lower extremity to opposite ends of a T lever 20, mounted on
a stud 21, (see Figs. 1 and 3).
Sliding in a slot on the lower portion of the Ț lever 20, is a small stud 22, attached
to the sliding horizontal rod 23, (see Figs. 2 and 5) the aforesaid rod 23, is supported
by the bracket 24, the end of the rod 23, nearest the bootjack 25, is of a fork shape, a
projecting portion of the bootjack 25, being in the middle of the fork, thus when the
T lever 20, is moved by the upright rods 18, or 19, the sliding horizontal rod 23, will
move the bootjack 25, into gear with the star wheel 32.
For working a double rise or drop of the shuttle boxes, the middle pattern needle 12.
(see Fig. 2) will be operated upon by the pattern cards, and the horizontal end of the
right angle lever 15, attached, will be raised and thereby lift the upright rod 26,
(see Figs. 1 and 4) the lower end of rod 26, is connected to one end of the fork 27,
mounted on suitable brackets 28, and 29, thus when the upright rod 26, is lifted the
fork will force the double lift cam 30, under the cam bowl 31, and cause the shuttle
boxes to skip a box in the usual manner.
In soine cases I propose to use a star wheel without the divided disc attached, my
star wheel 32, (see Figs. 1 and 3) consisting of two gear wheels connected together,
and both gears having an equal number of teeth to the inch, as has also the bootjack 25,
and the rack 33.
The rack 33, which is connected to the shuttle boxes, has grooves or slots in the
back of it into which a projection on the horizontal rod 34, work into, thus locking the
shuttle boxes, (see Figs. 1 and 3).
The horizontal rod 34, slides in the bracket 24, and is held in position against the
rack 33, by the spring 35. (See Figs. 1 and 3.)
The pattern cylinder 7, as aforementioned is placed at a convenient height from the
floor and is actuated by means of the grooved cam 36, (see Fig. 6) the bowl 37,
attached to the rod 38, works in the groove on the cam 36.
On the upper portion of the rod 38, is a slot, which slot is on either side of the
stud 39, which stud is attached to the angle lever 8, the bottom of the slot on rod 38,
is held into contact with stud 39, by the spring 40.
Thus the pattern cylinder 7, will receive a horizontal movement against the pattern
needles 11, 12, and 13, and the catch 41, will turn the pattern cylinder 7, and cause
it to revolve.
In the event of the weft thread breaking &c., to prevent the pattern cylinder 7,
continuing to revolve and the pattern cards from coming into contact with the pattern
needles 11; 12, and 13, an end of the swivel lever 42, having its centre on the stud 43,
is moved under the end of the angle lever S, (see Figs. 1 and 3) the aforesaid rod 38,
will still continue its usual movement as the spring 40, will yield, and allow the
stud 39, to work upwards in the slot on rod 38.. :

page_text: The opposite end of the swivel lever 42, to that which moves under the angle lever 8,
is connected to the horizontal rod 44, which rod working in suitable brackets under
the breast beam of the loom, is connected to the ordinary pattern setting on rod of the
loom.
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 :-
First The combination of the pattern needles 11, and 13, right angle levers 14,
and 16, upright rods 18, and 19, T lever 21, sliding horizontal rod 23, and bracket 24,
for controlling the bootjack 25.
Secondly-The combination of the star wheel 32, rack 33, and the bootjack 25,
having the same number of teeth to an inch.
Thirdly The combination of the pattern needle 12, right angle lever 15, upright
rod 26, fork 27, and brackets 28, and 29, for working a double lift of the shuttle-
boxes.
Fourthly The combination of the slots on the rack 33, and the horizontal rod 34,
and spring 35, for locking the shuttle boxes, and keeping the rack 33, into gear.
Fifthly The combination of the rod 38, stud 39, spring 40, and angle lever 9, for
giving a horizontal movement to the pattern cylinder 7.
Sixthly The combination of the swivel lever 42, and horizontal rod 44, connected
to the pattern setting on rod of the loom, to not allow the pattern cylinder 7, to beat
up its full distance in the event of the weft breaking &c.
Dated this 29th day of May 1890.
