Shuttle Manufacturer do hereby declare the nature of the said invention for
"IMPROVEMENTS IN SHUTTLES FOR LOOMS FOR WEAVING to be as follows:-
"
This invention relates to an improved arrangement for holding the bobbins in
shuttles for looms for weaving.
In carrying out my invention I employ a fixed head for the bobbin spindle.
The spindle is loose and its end is adapted to take into the fixed head, and when
placed in position it is securely held by means of a spring catch which takes into
a suitable notch in the spindle.
By this arrangement a bobbin being placed on the spindle it is merely necessary
to push the end of the spindle into the fixed head and the spindle will be auto-
matically locked by the spring catch. To remove the bobbin the spring catch is
raised and the bobbin and spindle can then be removed.

Shuttle 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:-
This invention relates to an improved arrangement for holding the bobbins in
shuttles for looms for weaving.
+
In carrying out my invention I employ a fixed head for the bobbin spindle.
The spindle is loose and its end is adapted to take into the fixed head, and when
placed in position it is securely held by means of a spring catch which takes into a
suitable notch in the spindle.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing in which figure 1 is a central
longitudinal section and figure 2 a plan of a shuttle for looms for weaving con-
structed according to my invention; figures 3 and 4 are transverse vertical sections
on the lines A, B and C, D respectively of figure 2; figures 5 to 9 are detached
views of the parts forming my fixed head; figures 10 and 11 are detached views
of the spring catch. Similar letters in all the figures represent similar parts.
a, is the body of the shuttle which is of ordinary construction; b, b, are the
shuttle wheels which are preferably made according to the specification of former
Letter's Patent granted to me dated the 9th February 1878 N° 550 and c, is the
usual bobbin..
My fixed head is constructed of a tube d, shewn detached in side elevation at
figure 5, which is driven into a hole made in the part of the shuttle a, where the
head of the peg or spindle for holding the bobbin is usually placed; the tube d,
has a shoulder e, at each end upon one of which I fit a plate f, (shewn in front and
edge views at figures 6 and 7 respectively) having a hole a¹, for this purpose and
a semi-circular boss or projection g, the plate being fastened to the shuttle a, by
means of screws h, h, as shewn in figure 4; on the opposite shoulder e, of the
tube d, I fit a plate i, shewn in front and edge views at figures 8 and 9 respectively
and provided with a hole b¹, corresponding to the hole a¹, and for a similar
purpose; I attach the said plate i, to the shuttle a, by screws j, j, as shewn in
figures 1 and 3; the plate i, is formed with a projection k, above the hole b¹, and
with a stop or projection 1, opposite the said hole; the plates f and i, serve to
prevent the tube d, from moving in any direction; m, represents the bobbin
spindle which is loose and is adapted to fit closely in and be passed through the
tube d, of the fixed Bead, the stop or projection 7, preventing its entering the same
too far; n, is the groove in the end of the spindle m, which enters the fixed head
and o, is a head on the free or opposite end of the same, the grooved end of the
spindle extending for some distance past the end of the bobbin; p, is the spring
shewn detached in longitudinal section and face view at figures 10 and 11
respectively; q, is a slot in the spring p, which slot slides over the projection k,
which acts as a guide to the spring which is fixed on the top of the shuttle a, as
shewn in figure 1, r, representing the screw. therefor; the slot is contracted in
size at its lower end so as to just admit the groove n.

page_text: By this arrangement a bobbin c, being placed on the spindle m, it is merely
necessary to push the end of the spindle into the fixed head, at the same time
pressing downwards the spring p, which will be guided by the projection k, so as
to always ensure its coming in proper position across the hole in the tube d, to
catch, with the reduced part of the slot q, the grooved end of the spindle m; the
spring p, is then released and the spindle will be automatically locked thereby.
To remove the bobbin c, the spring catch p, is depressed and the bobbin and
spindle can then be removed.
'
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. In a shuttle for looms for weaving the use of a fixed head or tube adapted to
receive the end of a loose bobbin spindle in combination with a spring for securing
the spindle in position substantially as hereinbefore described and represented in
the accompanying drawing.
2. In a shuttle for looms for weaving the peculiar construction of spring p,
having a slot q, contracted in size at its lower end so as to catch and retain the
grooved end of the bobbin spindle substantially as hereinbefore described and
represented in the accompanying drawing.
3. The improved shuttle for looms for weaving hereinbefore described and
represented in the accompanying drawing.
