Improvements in: Loom Pickers.
I JOHN GREENWOOD of 71, Partington. Street, Castleton near Manchester in
the County of Lancaster, Traveller, do hereby declare the nature of this invention
to be as follows:-
This invention relates to pickers for overpick looms in which the picking band
is attached to the top with its broad side horizontal or parallel to the picker
spindle and consists in an improved construction or formation of said pickers..
The several attempts. to make pickers with the picking band attached in the said
manner in order to obtain a straight pull in the direction, of the, spindle and avoid
the twisting of the band during the picking and the lateral canting of the picker,.
bave not been successful hitherto. In some cases the pickers have been. formed
with separate tops attached to the picker body which shake loose and break under
the rapid succession of the numerous blows pickers are subjected to in the loom.
In other cases the top has been formed of a strip or tongue solid with one side of
the picker and bent over and fastened to the other side for which purpose the
picker body must be made-solid in the upper part in order to fasten the end of the
tongue, in consequence of which there has been too much friction and beating of
the spindle, while the fastenings also work loose and. break. The object. of my
invention is to obviate these defects.
In carrying out my invention I form the picker out of one sheet. of hide or its,
equivalent or of two thinner sheets of the same size, placed one on the top of the
other-which is cut in the same shape as for making an ordinary scooped picker.
but of a greater height, the addition being about equal in height to the thickness
of the finished picker at the top. From each side I cut a slot into the sheet so that
the aforesaid additional piece is connected to the remainder only for a width equal.
to the length of the back of the. finished picker, and narrow down the. two free
ends thus formed by about the thickness of the hide in each side. I then bend the
additional part over at a right angle with the back, and the. two free ends at a
right angle to the central part, and then fold the rest of the sheet in the usual.
way for forming.a scooped picker, enveloping the two free ends of the top part in
the borns of the picker, and pressing and fixing the. folds.by a wire clamp or clamps
in the usual way.
In this way a picker is formed like a scooped picker with a continuation of the
back folded over the tops of the horns and held down by the ends.embedded in the
borns: In pressing I curve or bulge out the top part between the horns and also
preferably press the back next to the top outwards, so that two cross slots, cut
into the curved top part of the same width as the picking strap, are in a central,
position to the picker spindle holes: The back part opposite the spindle may be
perforated to promote circulation of air round the same.
The picking strap is attached by being drawn through the two slots and a wood
peg or its equivalent passed through the end..

page_text: I, JOHN GREENWOOD of 71 Partington Street, Castleton near Manchester in
the County of Lancaster, Traveller, 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 pickers for overpick looms in which the picking band is
attached to the top with its broad side horizontal or parallel to the picker spindle
and consists in an improved construction or formation of said pickers.
The several attempts to make pickers with the picking band attached in the said
manner in order to obtain a straight pull in the direction of the spindle and avoid
the twisting of the band during the picking and the lateral canting of the picker,
have not been successful hitherto. In some cases the pickers have been formed
with separate tops attached to the picker body which shake loose and break under
the rapid succession of the numerous blows pickers are subjected to in the loom.
In other cases the top has been formed of a strip or tongue solid with one side of
the picker and bent over and fastened to the other side for which purpose the
picker body must be made solid in the upper part in order to fasten the end of the
tongue, in consequence of which there has been too much friction and heating of
the spindle, while the fastenings also work loose and break. The object of my
invention is to obviate these defects.
On the drawing appended hereunto.
Figure 1 shows a front view of the improved picker.
Figure-2-an-end-view..
Figure 3 a top view.
Figure 4 a section along line x-x in the upper part and along line y-y in the
lower part.
Figure 5 shows the shape of the piece of hide the picker is made of reduced to
half size relatively to the other figures.
In carrying out my invention I form the picker out of one sheet A of hide or its
equivalent, Figure 5, which in the lower part a¹ is cut in a similar shape as for
making an ordinary scooped picker, but has added to it a part a² at the top, the
height of which in the middle part is about equal to the width b' of the top 6 of
the finished picker. From each side I cut a slot a into the sheet, so that the
additional part a is connected to the remainder only for a width n equal to about
the length of the top and back of the picker and narrow down the two free ends
flaps c thus formed as shewn on Figure 5. I then bend up the part a' with ends
at a right angle with the part a¹ to form the top 6 of the picker and bend the
flaps c at a right angle to the central part and then fold the lower portion al of the
sheet A over in the usual way for forming a scooped picker, enveloping the two
free ends c of the bent over top 6 in the sides or horns d of the picker, as shewn by
Figure 4. I then press the picker into the shape it is to assume, and fix the folds
by means of a wire clamp e or clamps in the usual way.
b
In this way a picker is formed like a scooped picker with a continuation 6 of the
back folded over the tops of the horns d and held down securely by the flaps
embedded in the horns. In pressing the picker I preferably curve or bulge ou
the top part 6 between the horns as shewn on Figure 1 and press the back nex
to the top boutwards, so that two cross slots g cut into the curved top part 6 of the
same width as the picking band are in an approximately central position relatively
to the picker spindle holes h. The back part may be perforated opposite the
spindle to promote circulation of air round the same.

page_text: In some cases the top and back may be left flat instead of being bulged out..
Instead of forming the picker out of one sheet, in some cases two thinner sheets of
the same size placed on the top of one another are used. The picking strap is.
attached by being drawn through the two slots and a wooden peg or its equivalent
passed through the end. By this mode of attachment the picking band is not
twisted while picking and the lateral canting of the picker prevented, whereby the
duration of the band and picker is prolonged.
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. The improved manufacture and formation of pickers substantially as herein--
before described and illustrated by the drawing.
2. The improved manufacture of a picker having a top with cross slots for the
attachment of the picking band formed solid with the back of the picker and attached
to the horns substantially as herein before described and illustrated by the drawing..
