PROVISIONAL SPECIFICATION.
Improvements in Shuttle Tongues for Looms.
We, THOMAS SHACKLETON, of Grantham Road, Bradford, in the County of
York, Shuttle Tongue Manufacturer, and WILLIAM HENRY HARGREAVES, and
ROBERT HOLLINGS DEWHIRST, both of Sunbridge Road, Bradford, aforesaid,
Engineers, do hereby declare the nature of this invention to be as follows:-
The object of this invention is the construction of and combination with shuttle
tongues of certain additional parts in such a manner that, they are applicable for
weaving both spool bobbins and tubes, and to so form the tongues that they will
allow the yarn to leave the bobbin or tube more freely by reducing the friction of
the yarn as it is leaving the bobbin or tube to such an extent that, all the yarn can
be drawn therefrom, also to be enabled to weave the yarn from bobbins or tubes
having cracked or otherwise damaged ends.
We accomplish our object in the following manner :-The shuttle tongue is
hinged to the shuttle block in the manner as hitherto, and near to one end of the
tongue, a slot hole is cut for the reception of the tongue spring.
On placing a bobbin or tube on a shuttle tongue, the end nearest the shuttle eye
is supported by a tube fitting on the end of the said tongue and held in position by
a spring, the end of the tube being prepared with a flange larger in diameter than
that of the bobbin or tube, so that, as the yarn is delivered, it passes over the
before mentioned flange without coming in contact with the bobbin or tube, thereby
reducing the friction on the yarn and the liability of entanglement with the bobbin
or tube.
By placing a flange at the end of the tube, the end of the bobbin or tube is
protected, so that, the yarn, as it is leaving, does not come in contact with any
rough or damaged portion and break the yarn as is now the case when weaving
with shuttle tongues of the ordinary construction.

COMPLETE SPECIFICATION.
Improvements in Shuttle Tongues for Looms.
We, THOMAS SHACKLETON, of Grantham Road, Bradford, in the County of
York, Shuttle Tongue Manufacturer, and WILLIAM HENRY HARGREAVES, and
ROBERT HOLLINGS DEWHIRST, both of Sunbridge Road, Bradford, aforesaid,
Engineers, 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 has for its object, the combination with shuttle tongues of certain
additional parts in such a manner that they are applicable for weaving the yarn
from both spool bobbins and tubes, and to so form the tongues that they will allow
the yarn to leave the bobbin or tube more freely by reducing the friction of the
yarn as it is leaving the bobbin or tube to such an extent that all the yarn can be
drawn therefrom; also by our improvement to be enabled to weave the yarn from
the bobbins or tubes having cracked or otherwise damaged ends.
In order that our invention may be fully understood we will describe the same
by making reference to the accompanying sheet of drawings in which
Fig. 1. represents a section through an ordinary loom shuttle fitted with our
improved tongue and additional parts attached.

page_text: Fig. 2. a detail of the tongue partly in section with the additional tube thereon
in section.
Fig. 3. a modification of same.
Fig. 4. a view of the shuttle tongue, and
Fig. 5. a view of a shuttle tongue having the spring attached to the point
thereof.
The shuttle tongue head A. is hinged to the shuttle block B. in the manner as
hitherto, and near to the opposite end of said tongue a slot hole C. is cut for the
reception of the end of tongue spring D.
On a bobbin or tube containing the yarn being placed on the shuttle tongue A11
the end nearest the shuttle eye E. is supported by the additional tube F. which is
securely held in position between the shoulder G. formed on the shuttle tongue or
at G' on the spring D. and the projection or catch H. at the end of said tongue by
the spring D.
The end of the additional tube F. is prepared with the flange K. larger in
diameter than that of the yarn bobbin or tube, so that as the yarn is delivered
from the bobbin or tube, it passes over the flange K. without coming in contact
with the bobbin or tube, thereby reducing the friction on the yarn and the liability
of entanglement of the same with the yarn bobbin or tube. By placing the
flange K. at the end of the additional tube F. in the manner shewn and described,
the end of the bobbin or tube is protected, so that, the yarn as it is leaving the
same, does not come in contact with any rough or damaged portion there may be
on the bobbin or tube and thereby endanger the yarn of being broken as is now
the case when weaving with rough or otherwise damaged bobbins or tubes placed
on shuttle tongues of the ordinary construction.
When the movable tube F. is placed on the shuttle tongue A¹ the end of the
spring D. is shown inserted in the slot hole C. cut in the said tongue, but it will be
easily understood that by forming a spring such as is shown by Fig. 6. it will allow
the tube F. to be placed on the shuttle tongue and retain same in position
thereon.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The combination of the parts forming the shuttle tongue A' and the movable
tube F. arranged substantially as and for the purpose herein set forth and illustrated
by the accompanying drawings.
