page_text: We, GEORGE HERBERT HODGSON, and MALCOLM ELLIOT HODGSON, and GEORGE
HODGSON LIMITED, all of Frizinghall Works, Bradford, in the County of York,
Machine Makers, do hereby declare the nature of this invention to be as follows:--
This invention relates to improvements in looms for weaving the object being
to reduce the number of working parts and so to greatly simplify the mechanism
required for conveying the motion from the primary driver to the shedding mech-
anism, and to the letting off and taking up motions in such a manner that in the
event of a fault occuring in the weaving the shedding mechanism, cylinder or
pattern surface, and the let off and take up motions can be turned back by hand
by disconnecting one clutch only instead of three as heretofore. The several
motions being all reversed or turned back at one and the same time compensates
for any faulty picks which it may be necessary to take out of the piece.
According to this invention we employ a vertical shaft on which is a loose long
collar or sleeve and a bevel wheel driven by a like wheel from the crank shaft
of the loom. On the collar or sleeve is also a clutch engaging with a correspond-
ing clutch fixed on the vertical shaft.

We, GEORGE HERBERT HODGSON, and MALCOLM ELLIOT HODGSON, and GEORGE
HODGSON LIMITED, all of Frizinghall Works, Bradford, in the County of York,
Machine Makers, 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 looms for weaving, the object being
to reduce the number of working parts and so to greatly simplify the mechanism
required for conveying the motion from the primary driver to the shedding mech-
anism, and to the letting off and taking up motions in such a manner that in the
event of a fault occuring in the weaving, the shedding mechanism, cylinder or

by disconnecting one clutch only instead of two or three as heretofore. The several
motions being all reversed or turned back at one and the same time compensates
for any faulting picks which it may be necessary to take out of the piece.
Such being the nature and object of our said invention, the following is &

page_text: complete description of same, reference being had to the annexed drawings, in
which:-
Fig. 1 is a side elevation of the improved driving mechanism for looms for
weaving.
Fig. 2 is an end view of Fig. 1.
According to this invention we employ a vertical shaft 1 on the top of which
is a bevel wheel 2 gearing with and driving the bevel wheel 3 which com-
municates motion to the shedding mechanism. At or near the bottom of the
shaft 1 is a strap eccentric 4 which by link 5 operates the "letting off" motion
and also a bevel wheel 6 gearing with and driving the bevel wheel 7 which in
turn communicates motion to the "taking up" mechanism.
on the
On the vertical shaft 1 is loosely mounted the long collar or sleeve
bottom of which is the bevel wheel 9 gearing with and driven by the bevel wheel 10
on the stud 11 which in turn is driven by the train of wheels 11, 11* from the
main shaft or primary driver 12. The top of the collar or sleeve 8 terminates
in the clutch plate 13 forming part of the clutch 14 which can be moved up and
down on the shaft 1 but revolves with the latter being keyed thereon by means
of a long key.
The clutch 14 can be thrown in and out of gear with the plate 13 by means
of the forked lever 15 and hand lever 16, and when in gear it will be seen that
the shedding mechanism, "letting off," and "taking up motions are all driven
from the vertical shaft 1. In event of a fault occuring in the weaving, or if for
other reason it is desired to turn back the shedding mechanism, the clutch 14
is thrown out of gear with the plate 13, whereon the long sleeve or collar 8
revolves loosely on the shaft 1 and the latter can be turned back by means of the
hand wheel 17 and bevel wheels 3, 2, and the shedding mechanism and "letting
off" and "taking up" mechanism are at the same operation turned back.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
(1) The improved driving mechanism as and for the purpose herein described
and substantially as illustrated by the annexed drawings.
(2) The vertical shaft 1, long collar or sleeve 8 bevel wheel 9 and clutch plate 13
loose thereon together with a clutch 14 keyed on but free to be moved up and
down the shaft I all in combination as and for the purpose herein described and
substantially as illustrated by the annexed drawings.
