and in other Parts in Connection therewith.
I SMITH HARTLEY, of Union Shed, Skipton-in-Craven, Yorkshire Manufacturer, 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:
That is to say it consists of improvements in the construction or formation of the
spindles of shuttles used in looms for weaving and in other parts in connection there-
with, whereby said spindles are more securely fixed or attached to said shuttles, and
the bobbins used in connection with same may be larger without adding to the size of
the shuttle, said bobbins being also rigidly and firmly held, with the advantages well
known to those versed in this class of machinery.
In order that this invention may be more readily understood I have hereunto
appended a sheet of drawings illustrative thereof to which reference is made in the
following description and in which fig. 1 is a part-sectional side view of a shuttle with
spindle and parts attached, fig. 2 being a view as seen from above, of a complete
shuttle with spindle, parts and bobbins, and fig. 3 being a similar view to fig. 1 but
including the bobbin, while fig. 4 is detail drawing hereinafter referred to.
A suitable opening is made in the end of the shuttle a for the reception of the
end (which is preferably of square or rectangular shape in cross section) of the
spindle c, the sides dd of said shuttle a preventing any lateral movement of said
end while the pins e e aided by the bottom part of said shuttle a secure same in
other directions.
The other end g of said spindle c is made of a suitably curved shape (see fig. 1)
having a hook / formed at its extremity so that in addition to securely holding the
bobbin i, by its elasticity or springiness keeping the hook in connection with the
upper edge of the outer end of said bobbin i as shewn by fig. 3, said curved shape
enables or allows said bobbin i to be detached therefrom, without requiring the
spindle c to be hinged as is usual, which hinging, together with the spring used in
connection with same, lessens the space for the reception of the bobbin in the shuttle
as is well understood.

page_text: Additional strength is given to spindle c towards its fixed end, by forming the part k
thereon, which part also assists in the holding of the bobbin i.
To prevent the bobbin i from revolving on its spindle c a piece m is fixed, by the
pin n, above the end of said spindle c, one end of said piece m being made to enter
the grove o which is made in the end of said bobbin i.
By the bobbin i being securely fixed as herein before described, I am enable to
employ means for putting more than the usual amount of "drag" upon the weft s
whereby the tension of such weft thread is always sufficient to draw it tightly against
the edges of the piece so that said edges appear more uniform and loss of weft thereby
is avoided. This I attain by placing a brush p and p³ on each side of the shuttle a
(said brushes being formed of threads of weft or warp and fixed as is well understood),
the brush p being made larger than the brush p when the weft s is unwound from the
bobbin in the direction shewn by the arrow y so as to better enabled to catch said weft
thread s.
P
Beneath the brushes and p² are stretched the threads of fibre r (shewn by detail
drawing fig. 4, which is a cross sectional view of fig. 2), which prevent the weft from
getting downwards out of contact with the brushes p and p¹.
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 :
1. The spindle e having its ends b and g respectively formed as herein described
and illustrated, and the pins e e in combination with the piece m and the pin n
substantially as and for the purposes specified.
2. The brushes 2 and p', and the threads of fibre in combination with the spindle c
having its ends 6 and 7 respectively formed as herein described; and the pins e e
substantially as and for the purposes specified.
