PROVISIONAL SPECIFICATION.
Improvements relating to Weavers' Loom Shuttles.
I JAMES WADDINGTON Holme Top Mills Little Horton Bradford in the
County of York Shuttle Maker do hereby declare the nature of this invention to
be as follows, that is to say :-
This invention relates to improvements combining a cushion spring and cover in
combination with a shuttle tongue such as employed in weavers loom shuttles having
for their object the prevention of the sloughing of the spool the protection of the
bobbin end by the intervention of the cushion spring also the prevention of the weft
from entanglement with the delivery end of bobbin or cushion spring at the same
time protecting the latter from grease and dirt.
To effect these improvements I employ a rubber or spiral spring in combination
with a cap or cover which I mount on the end of the tongue nearest the
shuttle eye.
The delivery end of the spool bobbin when placed in working position on the
shuttle tongue bears against the cushion spring the latter being mounted inside the
cap or cover and is thus thoroughly shielded against grease and dirt or entanglement
with the weft.
The cap or cover I make a little larger in diameter than the delivery end of the
bobbin therefore the weft when in the act of unwinding is supported on the outside
of the cap or cover and kept clear of the delivery end of bobbin and free from
entanglement with the cushion spring which as before stated is inside the cap or
cover It will now be seen that by the employment of this invention split or cracked
bobbins may be utilised as the cover or cap protects the weft from contact with the
delivery end of bobbin the cushion spring serving to relieve the sudden shock and
acting as a preventative against the damaging of the bobbin end or the sloughing of
the spool consequent on the sudden picking or stoppage of the shuttle.

COMPLETE SPECIFICATION.
Improvements relating to Weavers' Loom Shuttles.
1, JAMES WADDINGTON, of Holme Top Mills, Park Lane, Bradford, in the
County of York, Shuttle 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 :—
This invention relates to improvements in that type of weaving shuttle in which
loose or removable shuttle tongues are employed and its object is to provide a spring
buffer or spring stop at the end of the peg nearer to the weft eye of the shuttle for
the delivery end of the spool or bobbin to bear against and thereby cushion that end
of the bobbin (that is to say, reduce the shock caused by the picking of the shuttle)
which besides preserving the bobbin checks the tendency of the weft to "slough" or
slip off the bobbin.
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification, in which similar letters of reference indicate corresponding parts
in each of the figures.

page_text: Figure 1, represents a longitudinal section of a shuttle having an india rubber
buffer also shown in section fitted on the tongue in accordance with my invention.
Figure 2, represents a separate view of the tongue and buffer in full.
Figure 3, represents an end view of the tongue and buffer.
Figure 4, is also a separate view of a shuttle tongue fitted with a spiral spring
buffer.
Figure 5, is a similar view to Figure 4 with the spring buffer shown in section.
Figure 6, represents an end view of Figure 4.
The shuttle A is represented broken away at one end and the tongue B is secured
therein in the manner for which Letters Patent No. 223 were granted to me and
others on the 5th day of January 1893. The bobbin C shown in section in
Figure 1, is mounted on the tongue in the ordinary way.
The hollow cap D is loosely mounted on and against the head E of the tongue B
and the india rubber buffer F is also mounted upon the tongue and lies within
the cap D thus forming a cushion between the end G of the bobbin and the
head E of the peg. The raised bead H surrounding the outer periphery of the
cap D also forms a guide for the weft as it leaves the bobbin and keeps it from
coming in contact with or catching the end of the bobbin.
In Figures 4, 5 and 6 a spiral spring F1 is shown instead of india rubber,
and a washer F is mounted upon the spindle to form a bearing for the end of the
bobbin.
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. In a weaving shuttle fitted with a loose tongue, the use of a spring stop or
buffer adjacent to or forming the head of the tongue, substantially as herein shown
and described and illustrated in the accompanying drawings.
2. In a weaving shuttle fitted with a loose tongue, the combination with the
tongue of a hollow cap or head containing a spring stop or buffer, substantially
as herein shown and described.
3. In a weaving shuttle fitted with a loose tongue, the combination with the
tongue of a hollow cap or head forming a guide for the weft leaving the bobbin
and adapted to enclose a spring stop or buffer, substantially as herein shown and
.described.
