PROVISIONAL SPECIFICATION.
Improvements in the Method of Mounting Loom Shuttle Tongues.
I, JAMES WADDINGTON, of Holme Top Mills, Little Horton, Bradford, in the
County of York, Shuttle Manufacturer, do hereby declare the nature of this
invention to be as follows
This invention is applicable to shuttles having interchangeable tongues and to those
having split or other tongues now in common use; and has for its object, the con-
struction of the tongue heads in such a manner that, when mounted in the shuttle
block more support is given to the tongue heads, and in such a way that, the ends of
the tongues are firmer, and not so liable to rise when crossing a loom, and thereby
damage the fabric, as when mounted in the usual manner.
I accomplish my object in the following manner : Each shuttle tongue head is
centred somewhat in the ordinary manner on a pin passing through the shuttle block,
but in addition to this, I secure two rest pins, one on each side the intermediate or
centre pin, one being above, and the other below the centre of the shuttle tongue:
the tongue head having recesses cut therein which receive the rest pins when the
tongue is in its normal position.
In connection with each tongue head I fix a spring, so arranged, that one end rests
upon and presses the tongue head, so that it is supported by the before mentioned rest
pins entering the recesses cut in the tongue head; and by the spring being formed so
as to exert its force upon the tongue head at a point between the under or front rest
pin and the end of the tongue nearest the shuttle eye, greater stability is gained and
the liability of damage to the warp threads or fabric minimised.
In the case of interchangeable tongues, the rest pins are arranged in a similar
manner, but the position of the centre or intermediate pin is away from the centre
line of the shuttle tongue, so as to allow of the insertion of the shuttle tongue into the
centre of the tongue head; and when the tongue is raised for changing the same or
bobbin, the head is moved into such position that it is held at an angle by means of
the before mentioned spring.
The tongue is supported by being inserted in a hole bored in the tongue head, and
has recesses cut to correspond with the rest pins, which when the tongue is lowered to
its normal position make it secure: thus by these means, I am enabled to apply
tongues of different lengths whenever required, to suit the bobbins on which the weft
is spun and prevent the tongue rising when not required.

COMPLETE SPECIFICATION.
Improvements in the Method of Mounting Loom Shuttle Tongues.
I, JAMES WADDINGTON, of Holme Top Mills, Little Horton, Bradford, in the
County of York, Shuttle Manufacturer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention is applicable to shuttles having interchangeable tongues and to
those having split or other tongues now in common use; and has for its object the
construction of the tongue heads in such a manner that, when mounted in the
shuttle block more support is given to the tongue heads, and in such a way that,
the ends of the tongue are firmer, and not so liable to rise when crossing a loom

page_text: and thereby damage the fabric, as is sometimes the case when mounted in the usual
manner.
In order that my invention may be fully understood, I will proceed to describe the
same by reference to the accompanying drawing showing my improvements in
combination with a shuttle.
Fig. 1. represents a section through an ordinary loom shuttle fitted with my
improved tongue head suitable for an interchangeable tongue.
Fig. 2. is a similar view with the tongue head raised to the position for changing
the tongue, bobbin or the like.
Fig. 3. an enlarged view of my improved shuttle tongue, with an interchangeable
tongue inserted, and
Fig. 4. a section through an ordinary shuttle fitted with a split tongue having the
tongue head arranged according to my invention.
The shuttle blocks are constructed as hitherto, and the shuttle tongue heads are
centred in the block somewhat in the usual manner. In Figs. 1 and 2. the shuttle
tongue head A. is centred in the shuttle block on a pin B. passing therethrough, but
in addition to this I insert two rest pins C and D. for supporting the shuttle tongue.
In the case of interchangeable tongues E. the centre or intermediate pin B. is below
the centre line of the shuttle tongue head A. in which a hole is bored for the
reception of the tongue E. the bottom rest pin C. is placed somewhat nearer to the
centre of the shuttle than pin B. and the top rest pin D. is about the same distance
from the centre as C. but above, towards the top of the shuttle.
or
The shuttle tongue heads A. for interchangeable tongues, have recesses
indentations C and D cut therein to such depth as to clear the rest pins C. D.,
so that when the head is in its normal position and an interchangeable tongue
inserted in the manner as hereinafter described, the latter is securely held in a
suitable position for allowing the weft to leave the shuttle when weaving.
Each shuttle tongue head A. has a hole bored in same in its longitudinal direction
for the reception of a shuttle tongue E. which has recesses cut therein in such
positions as to correspond with the before mentioned rest pins C and D. so that when
a tongue is inserted and lowered to its normal position as shown by Fig. 1. the rest
pins engage with the recesses cut in the tongue and thereby support the same, the
tongue being kept in its normal position by means of spring F. arranged to press
upon the upper side of the tongue head somewhat as shown, so as to exert its force
upon the tongue A. between the rest pin C. and the end nearest the shuttle eye G.
thereby obtaining greater stability to the tongue, with less liability of damage to the
warp threads or fabric by the end of the tongue rising on the shuttle being driven
across the loom.
When it is desirable to change a bobbin or the like, the shuttle tongue is raised
until the end of spring F. passes over the end of the shuttle head as shown by Fig. 2.
by which means the tongue is automatically held in the required position for replacing
a tongue, bobbin or the like.
When constructing shuttles having split or other tongues now in common use, the
shuttle tongue head H. is centred somewhat in the ordinary manner on a pin J.
passing through the shuttle block, but in addition to this pin, I insert two rest pins K
and L. one being above and the other below the centre of the shuttle tongue, the tongue
head having recesses cut therein to receive the rest pins, the latter supporting the
shuttle tongue in its normal position for delivering the yarn.
With tongues of this class I also fix a spring F. with its end terminating above the
shuttle head and which exerts its force on the same, in the manner as hereinbefore
described, so that the tongue is firmly retained and supported in its required position.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination with a loom shuttle block of a shuttle head A. having a hole
bored longitudinally in the same for the reception of a shuttle tongue and with

page_text: recesses C¹ and D¹ cut for clearing the rest pins C and D. the tongue and head being
secured in the required position by means of spring F. operating on the tongue head
substantially in the manner and for the purpose as hereinbefore set forth.
2. The combination with a loom shuttle block of a shuttle tongue having recesses
cut therein for the reception of the rest pins K and L. and held thereon by means of
spring F. operating on the tongue head substantially in the manner and for the
purpose as herein before set forth.
