Complete Specification Left, 26th June, 1894-Accepted, 28th July, 1894
I, JAMES WHITAKER of Ingrow near Keighley in the County of York,
Shuttle Maker, do hereby declare the nature of this invention to be as follows, that
is to say:
It relates to improvements in that class of loom shuttles wherein the spindle or
peg upon which the bobbin or spool is to be mounted is loose or detachable,:
and consists of constructing said spindles and the hub' parts in which they are
mounted in such a manner that the former are more firmly held and are rendered
less liable to deterioration than are those at present in use.
In accordance with my invention I construct the hub-part for carrying 'the
spindle as far as regards its hinging upon the shuttle, of a somewhat similar
formation as those at present in use, but instead of arranging it in its bearings so
that the spindle's holding pin is on that side of the hub's hinging pin towards the
central part of the shuttle I have it mounted on the other side of said hinging pin,
while the heel part of the hub is prolonged and left with a suitable transverse notch
so that on the spindle being inserted therein and turned down or'moved into position
in the shuttle its outer end which has a hollow groove formed 'across it, lays hold
of this holding pin which thus retains it in position so long as the hub is not
moved on its hinge.
On the other side of the hub's hinging pin approaching the central part of the
shuttle I also fix another cross or stay pin upon which the spindle descends when
turned down into the shuttle, this inner end of the hub part being also formed to
extend over said cross pin so as to maintain the spindle in its said position against
the said cross pin while assuming its said horizontal position.
In that part of the spindle which rests upon the inner cross pin, I form' a
small cross groove to give more bearing surface to the spindle at this part and
so prevent it from rapidly wearing and falling below its desired horizontal
position.
By forming the hub-part and spindle as above described, the full strength of
the spindle may be carried almost throughout its entire length the two small cross
grooves being the only parts cut away, while those at present in use are
weakened throughout a considerable portion of the part which forms their" only
bearing.

COMPLETE SPECIFICATION.
Improvements in Loom Shuttles.
I, JAMES WHITAKER of Ingrow near Keighley in the County of York, Shuttle
40 Maker, 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 relates to improvements in that class of loom shuttles wherein the spindle or
peg upon which the bobbin or spool is to be mounted is loose or detachable and
TD 21

page_text: consists of constructing said spindles and the hub-parts in which they are mounted
in such a manner that the former are more firmly held and are rendered less liable
to deterioration than are those at present in use.
In order that my said invention may be more readily understood, I have
hereunto appended a sheet of drawings illustrative thereof to which by figures and
letters, reference is made in the following description.
Fig. 1 is a longitudinal section of a loom shuttle and shows the spindle and
bobbin in position as when in use.
Fig. 2 is a top view of said loom shuttle.
Fig. 3 is a longitudinal section similar to Fig. 1, but of one end only of the
shuttle, and shows the peg and bobbin raised into position for the latter to be
detached from the former.
Fig. 4 is a sectional drawing enlarged scale showing the formation of the hub
and spindle.
Figs. 5, 6, 7 and 8 are similar views to Figs. 1, 2, 3, and 4 respectively and are
illustrative of a modification hereinafter explained.
In accordance with my invention I construct the hub-part a for carrying the
spindle b (over which the bobbin k takes) as far as regards its hinging upon the
shuttle c, of a somewhat similar formation to those at present in use, but instead of
arranging it in its bearings or upon its pivotal pin d so that the spindle's holding-
pin is on that side of this pin d towards the central part of the shuttle I place
it upon the other side of the pin d and towards the outer end of the shuttle c,
while the heel part of the hub a is prolonged and left with a suitable transverse
notch a' so that on the spindle & being inserted therein and turned down as shown
by Figs. 1 and 2, its outer end 6 which has a hollow groove formed across it, lays
hold of this holding pin f which thus retains it in position so long as the hub a is
not moved on its pivotal pin. d, thus the advantages attained by forming the cross
groove as near the outer end 6 of the spindle 6 is effected and which leaves the
body part of said spindle as strong as possible. This result may also be effected
by forming the hub a³ (see Figs. 5 to 8 inclusive) so that the transverse notch a² is
vertical therein and instead of the holding pin which extends across the shuttle,
the holding-pin which only projects a little into the cavity in which the hub a¹
is mounted, may be employed in which case the pivotal pin d' for the spindle b is
on the opposite side of said holding pin to that above described.
On the other end of the hub a I also fix in the shuttle c another cross or stay
ping upon which the spindle b descends when turned down as shown by Figs. 1
and 5, this end of the hub a is also formed to extend over this pin g (upon which
I mount the spring which acts in the well known manner) and spring at which
part it has a notch or cross groove m formed in it so that by a corresponding
shallow cross groove on the spindle 6 coming into contact with the said pin and
spring when the spindle is down as before described, this spindle b is maintained in
the horizontal and secured position desired.
The shallow cross groove of the spindle b which rests upon the spring and pin g
forms a greater bearing surface for said spindle b than would its cylindrical surface
resting upon that of the said spring and pin g by which means its rapid
wear and consequent liability to fall below its desired horizontal position are
prevented.
By forming the hub-part a and spindle bas above described, the full strength
of this latter may be carried almost throughout its entire length, the cross grooves
being the only parts cut away, while those at present in use are weakened
throughout a considerable portion of the parts which forms their only bearings.
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 combination in a loom shuttle of a spindle having cross grooves formed
near its rear end, a hub for receiving said spindle and having corresponding cross

page_text: grooves formed in it and retaining pins for holding said spindle within said hub all
these parts being formed and arranged to perform their respective functions
substantially as herein specified.
2. The combination in a loom shuttle of a spindle having cross grooves formed in
it, a hub for the reception of said spindle, retaining pins and a spring formed to
operate substantially as herein set forth and described.
