PROVISIONAL SPECIFICATION,
Improvements in or relating to 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
similarly as to the picker described in my Specification No. 6623 A.D. 1896, and
consists in an improved construction or formation of the picker. With the picker
described in my said specification the threading of the picking band through the
slots is somewhat inconvenient and a portion of the hide has to be cut away and is
wasted, which adds to the expense of making them. The object of the present
invention is to remedy these drawbacks. The improved picker is formed with a
raised ridge across the top, which ridge is slotted above the top for the band, so
that the band can be easily pushed straight through the slot. The raised ridge is
produced by forming the picker in the following manner: A piece of hide of about the
same width as used for an ordinary scooped picker, but greater in height by the
width of the ridge to be formed, has a slit cut into it on each side at a distance
from the top of the piece equal to this width of the ridge, and corners cut out at
the bottom for the foot as usual. The sides below the slit are then folded over in
the same manner as for forming a scooped picker, while the upper part is simply
doubled or folded together, and may be secured at the front edge by a rivet or
rivets. The picker is then widened out at the scoop and a portion of the doubled
part pressed down to form a flat top, leaving a raised ridge across the same. A slot
is then punched through the ridge for the picking band to pass through and the
picker secured below the scoop by wire staples as usual, while the two folds of the
ridge may be further secured by rivets.
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:-
:-

page_text: is attached to the top with its broad side horizontal or parallel to the picker spindle,
similarly as to the picker described in my Specification No. 6623 A.D. 1896, and
consists in an improved construction. or formation of the picker. With the picker
described in my said specification the threading of the picking band through the
slots is somewhat inconvenient, and a portion of the hide has to be cut away and
is wasted, which adds to the expense of making them.
The object of the present invention is to remedy these drawbacks. The improved
picker is formed with a raised ridge across the top, which ridge is slotted above the
top for the band, so that the band can be easily pushed straight through the slot.
The raised ridge is produced by forming the picker in the following manner:-
A piece of hide of about the same width as used for an ordinary scooped picker,
but greater in height by the width of the ridge to be formed, has a slit cut into it on
each side at a distance from the top of the piece equal to this width of the ridge, and
corners cut out at the bottom for the foot as usual. The sides below the slit are then
folded over in the same manner as for forming a scooped picker, while the upper part
is simply doubled or folded together, and may be secured at the front edge by a rivet
or rivets. Or, as a variation in detail, the slit in the sides of the piece of hide may be
cut higher up, or dispensed with and the superflous hide may be all folded over at
the sides instead of being partially cut away.
The picker is then widened out at the scoop and a portion of the doubled part
pressed down to form a flat top, leaving a raised ridge across the same. A slot is
then punched through the ridge for the picking band to pass through and the picker
secured below the scoop by wire staples as usual, while the two folds of the ridge may
be further secured by rivits.
But that the improvements may be better understood I will, with the aid of the
accompanying drawings, proceed more fully to describe means employed by me.
The same letters indicate corresponding parts wherever they occur.
Fig. 1 represents a plan view of a sheet of hide of a shape suitable for constructing
pickers in accordance with my invention.
Fig. 2 represents a vertical section of a completed picker folded and compressed
from a sheet as in Fig. 1 when such is cut at the sides by the two slits b; while Fig. 3
shows a vertical section at right angles to Fig. 2.
Fig. 4 shows a vertical section of a completed picker folded and compressed from a
sheet as in Fig. 1 when such is cut at the sides by the two slits 6¹; while Fig. 5
shows a vertical section at right angles to Fig. 4.
Fig. 6 shows a vertical section of a completed picker folded and compressed from a
sheet as in Fig. 1 when such sheet of hide is folded into a picker without cutting any
slit at all; and Fig. 7 is a vertical section at right angles to Fig. 6.
In Fig. 1 a is the sheet of hide which is cut away at the bottom corners, and
may be cut with slits at 6 or b¹ or may be folded into a picker without such slit
cuttings.
In Figs. 2, 3, 4, 5, 6, and 7, a is the folded sheet, and c is a supplementary
packing sheet customary to be inserted for strengthening the picker but which forms
no part of this my present invention.
In Figs. 2 and 3 a portion of hide is cut away from the sheet a as shown in Fig. 1,
above the slit b: in Figs. 4 and 5 a less portion is cut away above the slit as at b¹;
while in Figs. 6 and 7 no portion whatever is cut away. It therefore follows that in
the example shown by Figs. 2 and 3 the upper portion of the picker, as at a¹, is
composed of two single thicknesses of hide, which are joined together at the centre
to form the projecting ridge a². In Figs. 4 and 5 the upper portion becomes double
by the folding over of the portions marked a³; while in Figs. 6 and 7 both the
upper portion and projecting ridge are folded double the whole length of the side of
the sheet,

page_text: d is the slot punched in the projecting ridge for the attachment of the picking
strap or band, which projecting ridge forms the essential feature of my invention.
The vertical section shown in Fig. 6 is taken upon two lines or thereabouts,
namely x, x and y, y¹ in Fig. 7.
In each of the Figures 2, 3, 4, 5, 6, and 7 the rivits or fasteners are indicated
at e.
Variations in detail may be made such as in the size of the pickers, and whether or
not packing or strengthening prices are employed, as also in the proportions of the
various parts, without departing from the peculiar character of the invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
The improved picker manufactured by folding and compressing a sheet or sheets
of hide so as to form a projecting ridge with a slot therein on the top of such
picker in manner and for the purpose substantially as herein shown and described.
