Improvements in Mechanism for Operating Change Shuttle Boxes
of 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 to be as
follows:
1
This invention relates to improvements in mechanism for operating the change
shuttle boxes through one set of holes in the cards whereby plain pegging is
Becured and the same card commands the same box.
According to this invention I attach to one of the ordinary pattern levers a
pendant rod on the lower end of which is a runner received in a cam slot in a plate
free to move on a stud by which it is attached to the frame of the loom.
At one end of the plate is a fork which loosely clips a rod connected to the
ordinary clutch which controls the spaced toothed wheel which operates the star
wheels and by connections the box lever rod, and boxes.
On one of the star wheels is cast an eccentric which is loosely clipped by a fork
with an elongated arm which is connected by link to the pendant rod of the pattern
lever.

SPECIFICATION
Improvements in Mechanism for Operating Change Shuttle Boxes
of Looms for Weaving.
| 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 mechanism for operating the change
rising and falling shuttle boxes of looms for weaving by means of one set of holes
in the cards whereby plain pegging is secured and the same card will always
command the same box.
According to this invention I attach to each one of two of the ordinary pattern
levers a pendant rod on the lower end of which is a runner received in a slot in a
plate or lever free to move on a stud by which it is attached to the frame of the
loom.
At one end of the slotted lever or plate is a fork which loosely clips a rod for
operating the ordinary clutch which controls the spaced wheels which operate the
star wheels and by connections the box lever rod and boxes.
On the axes of the star wheels I cast or fix an eccentric which is loosely clipped
by a fork with an elongated arm which is connected by link to the pendant rod of
the pattern lever so that the said pendant rod can thereby be moved from one end
to the other of the slot.

page_text: 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 an end elevation of part of a loom frame with the improved apparatus
for purpose aforesaid fixed thereto.
Fig. 2 is a front or end view of Fig. 1.
Fig. 3 is an oblique view of a detail drawn detached in order more clearly to
shew its construction.
Each
According to this invention I attach to each of the two ordinary pattern
levers 1. 1 a pendant rod 2. 2* on the lower end of each of which is a clip 3, 3ª,
carrying a runner 4, 4ª, received in a slot 5. 5° in the plate or lever 6. 6*.
plate or lever 6. 6* (see Fig. 3) is mounted, and free to move on its stud 7, 7º, by
which it is attached to the bracket 8 bolted to the end frame 9 of the loom.
Cast to or forming part of each plate 6. 6" is a lever 10, 10° one end of which
terminates in the fork 11, 11 which loosely clips the collar 12, 12" of the vertical
rod 13, 13 carried in the long collar or socket 14, 14* carried by the bracket 8 and
fixed to the end frame of the loom.
The lower ends of the rods 13, 13ª extend beyond the collars or sockets 14, 14*
and when lowered (as hereinafter described) are lineable and in contact with the
cam or inclined surfaces 15, 15* formed on the bosses of the spaced or segment
toothed wheels 16, 16ª forming part of the ordinary clutch 17 which operates the
star wheels 18, 18* and by the ordinary connections the box rod lever, and change
rising and falling shuttle boxes.
On the axis or stud 19 19* of each star wheel 18, 18" I cast or fix an eccentric
or tappet 20 20* loosely clipped and enclosed by a loop 21 21" formed in the lower
end of an elongated arm 22, 22ª each of which is free to move on its stud or
pin 23 23 in the bracket 24 24* fixed to the end frame 9 of the loom. The upper
ends of each of the elongated arms 22, 22" are by links 25 25° connected to the
pendant rods 2. 2" of the pattern levers 1. 1ª. It will be seen that the parts are in
duplicate like parts being used in combination with, and connecting each star
wheel 18. 18 to its pattern lever 1. 1*.
The action is as follows:-When a change of pattern is indicated by say a hole
in the cards on the pattern barrel 26 then the one of the rods 2 (which is
connected to the pattern lever 1* operated) will slightly lower one end 6° of the
frame or lever 6 turning the latter on its stud 7 and its fork 11* (see Fig. 1) will
allow the rod 13ª to drop slightly so that its lower end extends (see 13 Fig. 2) to
and comes in contact with the inclined or cam face 15* of the boss of the segment
wheel 16 and as the bottom shaft 27 revolves the segment wheel 16ª is, by the
inclined or cam face 15* bearing against the rod 13, pressed into the clutch and
linable with the star wheel 18 which is operated thereby and the indicated and
required change given to the shuttle boxes."
When the partial turn is given the star wheel 18ª its tappet or eccentric 20*
will operate on the loop 21 and move the arm 22" on its pin 23* and its upper
end will by link 25* move the runner 4 and rod 2 to the opposite end of the
slot 5.
Now if another hole in the cards follows, the rod 2" will be slightly lowered and
being now at the opposite end 6 of the slot 5, that is at the other side of the fulcrum
stud 7 when the pattern lever 1 is lowered its weight together with the weight of
the rod 2 will depress the end 6 of the slotted lever consequently the fork 11ª is
raised and raises the rod 13" above and clear of the inclined or cam face 15° and no
change takes place, and the parts will remain in this position until a blank occurs
in the cards whereon the end 6 of the slotted lever will be raised and the fork 11°
lowered and the rod 13 will slide the segment wheel 16 into line with the star
wheel 18 as herein before described. The action and operation of each of the
duplicate parts is similar.
It will be seen that a like card always commands the same' box, that is if a hole
bring up a certain box, and another hole follows then no change takes place. }

page_text: Having now particularly described and ascertained the nature and object of my
said invention 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 constituting
the improved mechanism for operating and controlling the change rising and falling
shuttle boxes in looms for weaving as herein described and substantially as
illustrated by Figs. 1 and 2 of the accompanying drawings.
2. The pattern levers 1. 1ª pendant rods 2. 2ª slotted frames or levers 66°
vertical rods 13. 13 segment wheels 16. 16" star wheels 18. 18* eccentrics 20. 20*
looped arms 22. 22° and links 25 25° all in combination and as and for the purpose
herein described and substantially as illustrated by Figs. 1 and 2 of the accoin-
panying drawings.
3. The slotted lever or plate 6ª comprising the slotted part 6ª lever 10° and
fork 11, as and for the purpose herein described and as illustrated by Fig. 3 of the
accompanying drawings.
