Improvements in Card Mechanism of Change Shuttle Box Looms for
Weaving.
I, GEORGE HERBERT HODGSON of Bee Hive Works, Bradford 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 improvements in the card mechanism for controlling
the change shuttle boxes of looms for weaving the object being to obtain a certain
and rapid change of box as indicated by the pattern cards the barrel of which may
be revolved, or may have a rising and falling motion.
Such being the nature and object of the said invention the following is a
complete description of same reference being had to the accompanying drawings in
which-
Fig. 1 is a side elevation of the improved apparatus for purpose aforesaid as
applied to and in connection with a pattern barrel, having a rising and falling
motion.
Fig. 2 is an end view of part of Fig. 1.
Fig. 3 is a side elevation of the improved apparatus for purpose aforesaid, as
applied to and in connection with a pattern barrel which revolves on its axis.
Fig. 4 is an end elevation of Fig. 3.
Fig. 5 is a side elevation of apparatus to be employed when coupling with an
ordinary double lift shedding motion with plain pegging.
Fig. 6 is a modification of apparatus shewn by Fig. 5.
Fig. 7 is an end view of part of Fig. 6.
According to this invention, in connection with a pattern card and shuttle box
motion, in which the pattern cards have a single line of holes, and the barrel is
revolved, (see Figs. 3 and 4) (as distinguished from a card barrel having a double
line of holes, and lifted and lowered) upright rods 1. 1. are employed, and are free
to work through guide brackets 2. 2.
The lower ends of said rods 1. 1. rest on rim or boss 3. 3 of the ordinary segment
clutch wheels and discs 4. 4, on each of which is a tappet or eccentric 5 for purpose
of acting on the ends of the rods 1. 1. and lifting same as required, the upper ends
of said rods carry cranked arms 6. 6, and one limb 7 of the arm 6 carries the peg 8,
for the pattern cards 9, said arm 6 and peg 8 being lifted by the eccentric or
tappet 5, and carried clear of the cards 9 when the cylinder or barrel is being
turned in the ordinary manner, and when the eccentric has passed from under the
rod 1, the latter descends by gravitation, and the pattern pin 8 rests upon a blank
of the card 9, or passes through a hole as indicated. The said rods 1. 1, and
pattern pins 8. 8 can readily be raised by hand, and turned aside in the bearings 2. 2,
so as to be out of the way of the card barrel and cards 9, when it may be necessary
to "lag back," or turn back, or alter the relative order of the cards 9 on the card
barrel.
If a blank occurs in the card, the peg 8 opposite such blank is held up, and with
it limb 7 and rod 1, and no change takes place, but if a hole occurs in the card, the
peg
8 opposite thereto, passes through such hole, and is lowered along with the
limb 7 and rod 1, and the lower end of the latter on which is the runner 1ª comes
in contact with the inclined or cam surface 2ª cast on the face of the ordinary
segment clutch wheel 4, and the latter is thus moved sideways on its shaft 3, and
the teeth 4 are moved lineable with the teeth of one of the star wheels 11 (see
Fig. 1) and a partial turn is given thereto, and by the connecting link 11" to the
compound box lever 12ª and box rod and boxes.
When the card barrel has two lines of holes and a lifting and falling motion, (see
Figs. 1 and 2) like upright rods 1. 1 are employed, and the lower ends rest on the

page_text: boses 3. 3 of the segmental clutch wheels and discs 4. 4 which operate the star
wheels 11. Each of the first named wheels 4. 4 has a cam surface 2" 2" cast on its
face, which when it comes in contact with one of the runners 1" on the rods 1. 1, the
disc and segment wheel 4 is slided sideways on its shaft 3" and into gear with its
star wheel 11, and on the axis of one of the star wheels 11 is an eccentric 13,
motion to which is given by such wheel 1, and the eccentric 13 operates a fork 14,
the latter is thus turned on its fulcrum pin 15, and by link 16 and connection 17
gives a partial turn to the upright rods 1. 1, an arm 18 from the upper end is con-
nected with and imparts a sliding motion to a bar 19 in which is the pattern peg 8,
so that the latter is moved from partly across the pattern card, that is from one line of
holes to another line of holes, or to a blank, according to the order in which the
shuttles are required to be brought in line with the box, a like card always bringing
up the same box. There is an ordinary one star wheel 11 for each of the segment
wheels 4, so that one of the latter by being slided on its shaft, can be brought line-
able with its star wheel, and a partial turn given thereto. A spring 20 forces the
seginental clutch wheels 4. 4 outwards and away from one another when not acted
upon by one or other of the rods 1. 1.
When no pattern barrel or cards 9 are employed, but the shuttle boxes are to be
operated and controlled by any of the well known double lift shedding motions, I
employ appliances as illustrated by Figs. 5 and 6 of the drawings.
In Fig. 5 the jack lever 30° of the double lift shedding motion, is by strap 30
passing over guide pulley 31 connected to one end of a lever 30 free to turn on its
fulcrum 30, and the lever 30 has a cam face 31 which operates on a runner 32 on
the upper end of a lever 33 free to rock on its centre 34. The lower end of the
lever 33 is by rod 35 connected to a bell crank lever 36 on a fulcrum stud 37, and
the lever 36 is by rod 38 connected to the bell crank lever 39, which operates the
catch 40 for purpose hereinafter described.
The apparatus shewn by Fig. 6 is similar to that shewn by Fig. 5, but the jack
lever 30 is by strap 30 passing over guide pulley 31ª connected to one end of a
slide 35 carried in bracket 36" fixed to the top rail of the loom. In the slide 35*
is a cam slot 36 in which is received the runner 35 on the pendant rod 41, which
is connected to the horizontal lever 42, free to rock on its fulcrum 43, and one end
of the lever 42 is connected to the vertical rod 1. Above and below the rod 42, and
on the rod 41, coiled a spiral spring 44, which allows the vertical rod 1 and hori-
zontal lever 42 to move without breakage.
The action is as follows:-Referring first to Fig. 5. The jack lever 30° is
operated in the ordinary manner and when moving in an upward direction, it pulls
the strap 30°, and the top end of the lever 30, which turns on its fulcrum 30°, and
the tappet 31 wipes against the runner 32, turning the lever 33 on its fulcrum 34,
and by the rod 35 turns the bell crank lever 36 on its fulcrum 37, and by rod 38
turning the bell crank lever 39 on its fulcrum, and so pulling the catch 40 from
under the boss 41 fast on the vertical rod 1, and the latter is allowed to fall by
gravitation as soon as the cam 5 passes from under it, and when it falls, it acts on
the cam surface 2 on the face of the clutch wheel 4, and slides same on its shaft 3".
When the jack lever 30° is inoperative, and the cam 31 does not act on the
runner 32, a spiral spring such as 50 moves the several parts in a reverse direction,
and the catch 40 moves under the boss 41, when the vertical rod is raised, and the
latter is held up when the cam 5 passes from under the end, and no change of box
takes place until the catch 40 is withdrawn from under the boss 41.
Referring to Fig. 6: When the jack lever 30° rises as shewn, it by the strap 30°
pulls the slide 35 in its brackets 36, and the slot 36° acting on the runner 356, the
latter is raised, by the higher part of the slot and the lever 42 is moved on its
fulcrum, and lowers the vertical rod 1, so that the cam surface 2ª comes in contact
therewith, and the segmental clutch wheel 4 is slided on its shaft 3*, so as to be
lineable and gear with its star wheel. When the cam slot 36 has moved until the
runner 35 is in the lower part thereof as shewn, the parts are moved into the
position shewn, with the bottom of the vertical rod 1 clear above the cam surface 2*,

springs 44 prevent breakage of the parts, and allow of the vertical rods 1 being
raised by hand if desired.
In the several appliances shewn, the segmental clutch wheels 4 engage with
star wheels 11 of the ordinary box motion, and as illustrated by Fig. 1 of the
drawings.
Having now particularly described and ascertained the nature and object of the
said invention, and in what manner the same is to be employed I declare that what

tially as illustrated by Figs. 1 and 2 of the accompanying drawings, and as herein
