COMPLETE SPECIFICATION.
Improved Pickers for use in Looms for Weaving, in which what are
known as "Side Tip Shuttles " are employed.
I,THOMAS OXLEY of 18 Saint Mary's Parsonage Manchester in the County of
Lancaster Mechanical Engineer, 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 :-
"
:
My invention consists in improved pickers for use in looms for weaving in
which shuttles each provided with a tip at the side of each end and known as
"side tip shuttles are employed which are more durable and advantageous in
use than the pickers hitherto constructed and possess greater strength to resist
the blows to which they are subjected when the shuttles are struck by them than
the pickers hitherto constructed.
According to my invention I so employ and arrange the material of which each
picker is formed that the portions of such picker which slide upon the picker-
spindle and the portions which act upon the shuttle when the picker is in use
in a loom are formed in great part or entirely of the outer surface of the hide
of which the picker is formed so that such parts are less readily worn out or
injured when the picker is in use.
One form of picker constructed according to my invention is illustrated in the
accompanying drawing in. which Fig. 1 is a front view and Fig. 2 is an end
view. Figs. 3 and 4 are vertical and horizontal sections of the picker taken upon
the planes respectively indicated by the lines A, A. and B, B of Fig. 1.
A picker constructed according to my invention is formed of three pieces a, b, c
of hide of which the piece a is folded so as to enclose. the piece and is after-
wards bent or moulded into the required form and secured upon the piece < by
means of rivets d, the hole e for the insertion of the picking-band or strap being
afterwards formed in any suitable manner. The piece a of hide is folded so that
its longer edges are placed in contact with each other and are enclosed in the
interior. of the completed picker and preferably at about the middle part thereof
as indicated in Fig. 4. The piece a of hide is so folded that the surface of the
said piece of hide which is outermost in the completed picker shall be the outer
side of the hide while the other surface of such piece a of hide which was towards
the flesh of the animal.shall be wholly enclosed within the body of the completed
picker.
A picker constructed in the manner above described in reference to and
indicated in Figs. 1, 2, 3 and 4 of the accompanying drawing is more durable and
advantageous in use than those hitherto constructed for the reasons that the
interior surface of the eye finto which the picker-spindle is inserted is
formed of the outer surface of the hide except in so far as such eye is formed
of the edge c¹ of the piece c of hide, that the surfaces of the parts and y either
of which may be used to act upon the shuttle are mainly portions of the outer
surface of the hide and that the piece of hide being enclosed within the piece. a
of hide the piece is not liable to become displaced while the picker is in use.
In Figs. 5, 6, 7, and 8 of the accompanying drawing is illustrated another form
of picker constructed according to my invention and possessing the advantages in
comparison with that above described in reference to and indicated in and by
Figs. 1, 2, 3 and 4 of the accompanying drawing that instead of a piece c of hide
being secured between the parts of the piece a of hide which are secured together,
he portions of the picker which slide upon the picker-spindle and act upon the
buttle when the picker is.in-use are. formed entirely of the outer surface of the
ide and that the whole picker being still more securely bound together is still

page_text: more durable than that indicated in Figs. 1, 2, 3, and 4 above referred to. In
Figs. 5, 6, 7 and 8 of which Fig. 5 is a front view, Fig. 6 is an end view, Fig. 7 is
a section taken on the plane indicated by the line C, C of Fig. 5 and Fig. 8 is a
section taken on the plane indicated by the line D, D of Fig. 5, the same letters
of reference as are used in Figs. 1, 2, 3 and 4 are employed to indicate parts corre-
sponding to those above mentioned in regard to Figs. 1, 2, 3 and 4.
In the picker
illustrated by Figs. 5, 6, 7 and 8 the pieces a and 6 of which the picker is formed
are folded and employed substantially as in the picker illustrated in Figs. 1, 2, 3
and 4 but instead of a piece of hide being secured between the parts of the
piece a which are brought and secured together pieces c, d of hide are enclosed
within each of such parts of the said piece a of hide as is clearly indicated in
Figs. 7 and 8, the pieces and, of hide being secured within the piece a of
hide and in position within the substance of the completed picker by means of the
rivets d. In the picker illustrated in Figs. 5, 6, 7 and 8 the interior surface f
of the eye through which when the picker is in use the picker-spindle passes and
the faces g which may be used to act upon the shuttle are formed exclusively of
the outer surface of the hide of which the picker is formed and the whole picker
is very securely bound together.
It is obvious that the pieces c¹¹ of hide may be connected by a portion passing
around the eye and contained within the piece a of hide and that if the piece of
hide be sufficiently thick the pieces c', e may be dispensed with and also that
instead of each of the pieces b, c and e', c¹ of hide two or more pieces or sheets of
hide may be employed in order that the completed picker may be of any required
thickness.
In the formation and moulding of pickers constructed according to my invention
apparatus of any suitable kind may be employed and the pieces of hide to be
employed may be subjected to any kind of treatment which may be suitable in the
formation of the pickers from such pieces of hide.
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. For use in looms for weaving in which what are known as "side tip shuttles"
are employed a picker formed so that the parts to be in contact with the picker-
spindle upon which such picker will be placed while in use and the parts which
may be required to act upon the shuttle to be propelled by such picker are formed
mainly of the outer surface of the hide of which the picker is constructed and
composed of three pieces of hide one of which is so folded formed and moulded as
to enclose the second piece and is secured to the third piece of hide for the purposes
and substantially in the manner hereinbefore described in reference to and indicated
in and by Figs. 1, 2, 3 and 4 of the accompanying drawing.
2. For use in looms for weaving in which what are known as "side tip shuttles"
are employed a picker formed so that the parts to be in contact with the picker-
spindle upon which such picker will be placed while in use and the parts which may
be required to act upon the shuttle to be propelled by such picker are formed
entirely of the outer surface of the outermost piece of the hide of which the picker
is constructed and in which the outermost piece of hide is folded so as to enclose
the other piece or pieces of hide used in the construction of the picker for the
purposes and substantially in the manner herein before described in reference to
and indicated in and by Figs. 5, 6, 7 and 8 of the accompanying drawings.
Dated this Third day of June 1891.
