Complete Specification Accepted, 14th Dec., 1888
I, ANTHONY CLEGG of 14 Hardman Street Failsworth near Manchester in the
County of Lancaster Weaving Manager do hereby declare the nature of this invention
to bo as follows:-
This Invention relates to the means or apparatus for imparting motion to the
weft fork in underpick looms provided with scroll" picking motion and it
has for its object to operate the weft-fork hammer without the use of toothed
gearing.
These Improvements consist in connecting the weft fork hammer to the lever of
the scroll motion by means of a rod or link through which the motion originated
in the scroll is conveyed to the weft fork hammer. The gearing and apparatus
usually employed for imparting and conveying motion from the crank shaft to the
weft. fork hammer is omitted with the exception of the connecting rod or its
equivalent which is connected to the lever of the scroll motion as hereinbefore
described.
Dated this 12th day of January A.D. 1888.

page_text: I, ANTHONY CLEGG, of 14 Hardman Street Failsworth, near Manchester, in the
County of Lancashire, Weaving 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:
This Invention relates to the means or apparatus for imparting motion to the
weft fork in underpick looms provided with scroll picking motions, and it has for
its object to operate the weft fork hammer without the use of toothed gearing.
These Improvements consist in connecting the weft fork hammer to the lever,
of the scroll motion by means of a rod or link through which the motion originated
in the scroll is conveyed to the weft fork hammer. The gearing and apparatus
usually employed for imparting and conveying motion from. the crank shaft to
the weft fork hammer is omitted with the exception of the connecting rod or
its equivalent which is connected to the lever of the scroll motion as before
described.
I will further describe my Invention with reference to the appended sheets of
Drawings, in which A is the weft fork; B is the weft fork hammer; C is the con-
necting rod; and D is the scroll motion lever upon which there is secured or formed
a lug E or other means for attaching the connecting rod thereto. The scroll lever and
the scroll G are in other respects identical with or equivalent to the ordinary scroll
and lever forming part of the picking motion.
In ordinary looms, the connecting rod C is attached to the weft fork hammer above
its centre of oscillation so that the fork is timed with the shuttle. For this purpose
the weft fork hammer may be secured to the arm F which is pivotted to the loom side
at H. The rod Cis connected to the arm by means of a bolt passing through a slot
in the arm as shown, so that the motion of the weft fork may be increased or
diminished by shifting the position of the joint in the slot. It will be obvious that in
other cases or when required the rod may be connected to the weft fork hammer
below its centre of oscillation. It is evident also that the form of the connecting rod
will have to be varied from a straight line in order that it may clear the lay sword and
according to the conditions of its use.
The motion of the weft fork hammer is practically identical with the motion which
is obtained when the ordinary means for operating it are employed.
In the drawing, the loom side and part of the picking motion are indicated
by dotted outlines for the purpose of showing the relative positions of the
apparatus.

page_text: 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 :-
(1.) In looms having a "scroll" underpick motion, operating the weft fork hammer
from and by the scroll motion; substantially as and by the means hereinbefore described
and as illustrated by the accompanying drawing.
(2.) In looms having a "scroll" underpick motion, the combination with the scroll
and scroll-lever of a connecting rod attached at one end to the scroll-lever and at the
other end to the weft fork hammer; substantially as and for the purpose horeinbefore
described and as illustrated in the accompanying drawing.
