PROVISIONAL SPECIFICATION.
Improvements in Taking Up Motions for Looms.
I JAMES HOLGATE of No. 3 Elm Street, Burnley in the County of Lancaster
Manager, do hereby declare the nature of this invention to be as follows:-
--
1st. In forming a single bracket with suitable bearings to carry the taking up
mechanism, and be attachable to the loom, by which greater rigidity and truth of
its parts are secured, and better facilities for adjustment.
2nd. In attaching the retaining pawl to the bracket in lieu of the usual finger
rod, and so arranging the same to project sufficiently under the actuating pawl to
allow an adaptation of the present finger rod-connected with a lever for the use of
the weaver for raising both pawls out of gear, and at the same time doing away
with the movement of the finger rod during the operation of the loom, thus
reducing wear and securing better taking up.
3rd. In so arranging the change wheel shaft and bearings that the shaft shall
revolve and the bush carrying the same which is adjustable in a radial groove shall
be fixed. The shaft works through the centre of the bush whilst the nut which
holds it to the bracket is large enough to admit it through its centre and leave
sufficient metal to pull at. This ensures its being fixed near to where the strain is,
and further the arrangements make the present change wheels which are principally
of small bore about th inches come in.

COMPLETE SPECIFICATION.
Improvements in Taking Up Motions for Looms.
I JAMES HOLGATE of Number 3 Elm Street Burnley in the County of
Lancaster Manager 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 :-
The object of this invention is to improve the taking-up mechanism in looms,
make it better adapted for the successful working of my Patent 13039, 1891, and
make use of existing change wheels in connection therewith.
My improvements consist,
Ist In arranging and building the taking-up mechanism on a bracket which is
attachable to the loom. I prefer to make this bracket stand, as it were, on three
legs, which regulate the distance from the loom side. Two of the legs answer for
the bolts to pass through to fix the bracket to the loom, whilst the third is hung on
the sand beam pike, and answers as a link, round which the whole bracket and its
mechanism can be revolved till a suitable position can be got at to fix the bracket
clear of the moving parts, such as the sley, drop boxes, &c. The three legs besides
insuring contact and firm fixing to the loom-though such loom may be out of
square or twisted-insures accuracy and parallelism in boring or drilling the
bearings, for no matter whether such bearings be bored in a lathe, or drilled in a
drilling machine, or changed about, they always fall in the same position; that is,
they do not rock when on the face plate or bed; thus rigidity and truth are
secured.
2nd-Hitherto the retaining catch has been directly attached to a small rod, called
the finger rod. When the weft broke the fork operated the draw off levers, which,
by its arrangement through this finger rod, raised the retaining catch out of gear.

page_text: In my arrangement I attach the retaining catch-which works on a cast-iron bush
-to the bracket. Its disconnection with the long rod, and its superior bush and
rigid fixing, greatly improve its smooth working and increases its certainty of
action. I make use of the finger rod for attaching levers to, for raising the pawls
out of gear to allow of the successful working of my Patent 13039, 1891, for letting
back. I would observe that this arrangement leads to the finger rod being at rest
at all times except when the weaver requires to raise the pawls out of gear, which
can be done conveniently at the knocker off end of the loom. Thus the excessive
wear during the operation of the loom on what is usually a small wrought iron bar
is prevented.
3rd There exists at the present time large quantities of change wheels which
are chiefly of small bore-about finches-with bosses too small to admit of much
larger bore. To make these wheels useful I bave arranged a bush or shackle
through which works the shaft carrying the small pinion and change wheel. This
is a fixture attachable to the main bracket along a radial groove-radial from the
sand beam pike-to suit the various sizes of change wheels. The centre of this
radial groove is the centre of the variable change wheel shaft in preference to any
other radial groove, in order that there may be the least leverage or shifting
tendency when it comes to be strained in work. Providing the change wheels
were capable of large bore, say 14 inches diameter hole, then a fixed stud of
inches or so could be fixed in this radial groove on which could ride a boss,
carrying the change wheel and pinion, but in my arrangement here I reverse the
two elements, making the boss the fixture, and the shaft, with its change wheel and
pinion, moveable. These are also moveable laterally for throwing the mechanism
in and out of gear. The arrangement also prevents the change wheel and pinion
being pulled right off and dropped on the floor, which often breaks the frail
castings.
The parts lettered A is the bracket on which is built the taking-up mechanism.
The retaining catch D is fixed on the bracket A, working on a cast-iron bush,
and projects under the catch C so that upon the weaver operating the lever B,
through the finger rod F, the catches C and D are released, and allows of the
better working of my Patent 13039, 1891; whilst the arrangement reduces the wear
in the finger rod F.
Through the shackle P works the shaft L, on which is fixed the small pinion M
and the change wheel W, capable of sliding laterally to admit of being put in and
out of gear with the sand beam wheel S. The small clip U hangs on the shaft L,
to keep the wheels in gear. The shackle P, with its parts L, M, W, is secured-
as may be desired-along the radial groove G by the nut O, which, having a direct
pull, is firm and not so liable to shift.
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 :
1st. A single bracket, on which the taking-up mechanism is built, preferably one
that when fixed to the loom-touches at three points, or stands on three legs; as,
and for the purpose, herein described.
2nd. The attaching of the retaining catch D to the bracket A, and the arrange-
ment and method of releasing the catches C and D by the use of the finger rod as
herein described.
3rd. The parts lettered L, M, O, P, U, and their arrangement substantially,
and for the purpose as set forth in the foregoing Specification and shown in the
accompanying drawings.
