Improvements in the Construction of Pickers for Looms for Weaving.
I, HERBERT HIND, of Holme Top Mill, Little Horton, Bradford, in the County of
York, Loom Picker Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to the construction of loom pickers in a manner that,
when blocked or pressed into shape, the lower portion has a seam on one side only,
commonly called the front side; also to so shape the cutting that, when folded
and pressed, the cap or upper portion of the picker is strengthened to such an
extent, that the liability of breakage through the guide or spindle holes, hitherto
the weak part of the picker, is reduced.
In carrying out my invention the hide cutting is made with two of the sides
parallel, one longer than the other, these parallel sides I call the top and bottom
of the cutting, the bottom side being longer than the top; the connecting sides of
the cutting are at an angle to the top and bottom, all the sides being straight,
except at each bottom corner a small triangular piece is cut therefrom.
The cutting is folded and a packing piece inserted and held in position by the
folds, the top portion of the cutting is then brought over a portion of the packing
piece, to form the cap of the picker, after which, the sides are lapped over towards
the centre, and the folded shape placed into a press for blocking the folded hide
into the necessary shape, leaving the sides of the upper portion of the picker
more solid and stronger than is the case when the cutting is shaped and fapped
as hitherto.
Should the cutting be required to be blocked into a picker having a solid top;
after lapping over the top and sides as before mentioned, the upper portion is
blocked in a manner that a recess is formed and the top part brought further
over the roughly blocked folding is then placed into a press and finally blocked
upon shape, leaving the sides of the upper portion of the picker more solid than
has been the case when cut and folded in the manner as hitherto.
The blocked pickers may be wired and finished in the manner as hitherto.

Improvements in the Construction of Pickers for Looms for Weaving.
I, HERBERT HIND, of Holme Top Mill, Little Horton, Bradford, in the County of
York, Loom Picker Manufacturer, do hereby declare the nature of this invention
[Price 8d.]

page_text: 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 construction of loom pickers in a manner that,
when blocked or pressed into shape, the lower portion has a seam on one side only,
commonly called the front side; and to so shape the cutting that, when folded
or pressed, the cap or upper portion of the picker is strengthened to such an
extent, that the liability of breakage through the guide or spindle holes, hitherto
the weak part of the picker is reduced.
In describing my invention in detail, reference is made to the accompanying
sheet of drawings in which Fig. 1 represents a hide cutting suitable for construct-
ing my improved picker.
Fig. 2 represents the first fold of the hide cutting, embracing another cutting
or packing piece.
Fig. 3 the third fold of the cuttings ready for the rough blocking press.
Fig. 4 a view of the picker after blocking in the final press, and
Fig. 5 an end view of the same.
The remainder of the figures are hereinafter referred to, in all of which like
letters indicate like parts.
In carrying out my invention, the hide cutting A is made with two of the
edges B and parallel, one longer than the other, these parallel edges I call the
top and bottom of the cutting, the bottom C being longer than the top B. The
connecting sides 1) and E are at an angle to the top and bottom, and straight
except at each bottom corner a triangular piece FF is cut therefrom.
The cutting A softened in the usual manner is folded by hand, a packing piece G
being inserted which is held in position by folding the sides D and E over same
as shown by Fig. 2, the top portion of the cutting above the packing piece
marked B¹ is then brought over the packing piece G and folded sides D and E as
shown by dotted lines marked W in Fig. 2, in order to form and give strength
to what is termed the picker cap. The cutting thus folded is then further
folded by hand, the back part of the upper portion of the cutting being then
convex and somewhat semicircular as shown by Fig. 3 which represents a trans-
verse section through line 1-2 of Fig. 3 showing the sectional shape of the upper
portion of the hand folded cutting, the packing piece G being between the back
portion of the cutting A and the turned in or lapped edges of the cutting D
and E which are covered by the top portion B¹. The bottom portion of the
folded cutting is further compressed or folded to form the bottom portion of the
picker, the edges of the cutting being to some extent turned underneath somewhat
as shown by Fig. 3º representing a transverse section through line 3. 4 of Fig. 3,
and by dotted lines F2 in Fig. 3.
The hand folded cutting whilst still in a soft state is then placed in a press of
the ordinary construction for rough blocking the folded cutting, after which it
is finally pressed by suitable dies into the shape required, leaving the sides HH
of the upper portion of the compressed scoope or centre picker, as the case may be,
more solid and stronger than is the case when the cutting is shaped and lapped as
hitherto.
My improved form of cutting and method of lapping is also applicable for con-
structing what are known as solid top" pickers, this is accomplished by making
the cutting A a little longer but otherwise of the same shape, and lapping the
cutting over a packing piece in the manner as before described.
The lapping is then roughly blocked in a manner so as to form a deep recess
at J, the top K being brought over as shown by Fig. 6 representing a section
through the roughly blocked shape, which is afterwards placed in a press and
finally blocked into the required shape such as shown by elevation Fig. 7, leaving
the sides HH of the upper portion of the picker more solid than has hitherto
been the case when cut and folded in the manner as hitherto.
Fig. 8 is a plan of a "solid top" picker showing the picking strap hole in centre.
Fig. 9. is an end view, and

page_text: Fig. 10 an end elevation of a "solid top" picker arranged with a loop L cut from
the blocked picker in the ordinary manner.
The pickers may be wired at M and finished in the manner as hitherto, the
seaming of the pickers shown by the lines N being on one side only, and the
sides through which the spindle holes P are bored, strengthened by the intro-
duction of a packing piece inserted in the manner as hereinbefore described.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
-
The construction of loom pickers from hide cuttings such as shown by Figs. 1
and 2, the said cuttings being folded and pressed substantially in the manner as
hereinbefore set forth.
