Improvements in or relating to Shuttles for Weaving Woollen,
Worsted, and other Fabrics.
I, WALTER MORTIMER, of Long Row, Horsforth, near Leeds, in the County
of York, Weaving Overlooker, do hereby declare the nature of this invention to
be as follows:-
This invention relates to improvements in shuttles such as are used in looms for
weaving woollen, worsted, and other fabrics, and its objects are, first, to provide
a spindle or tongue capable of being drawn in a longitudinal direction to prevent
"sluffing" or breakage of the weft on the bobbin or cop; and, secondly, to
securely retain the spindle or tongue in position within the shuttle during the
weaving operation, and preventing it from rising and thereby damaging the warp
thread.
According to this invention the spindle or tongue upon which the bobbin or cop
is placed is jointed within the shuttle and retained within the same by means of
the ordinary spring. But in order to prevent it rising when the shuttle is at work,
a spring is formed in one or more parts suitably fixed by any convenient means
within the shuttle. The said spring or springs is armed with a catch arranged to
pass across the top of the shank of the tongue for preventing it from rising when
the shuttle is at work.
The tongue of the shuttle is made in one or more parts, that is to say, the
tongue may be made to slide through its shank or heel that is in two separate
pieces connected together by a sliding piece or coupling arranged to slide in
a recess formed in the shank in which may or may not be also cut one or more
grooves in which a sliding piece,-in which the end of the tongue is secured-works.
The sliding piece is retained in position when the spindle or tongue is closed to its
working position by the sides of the shuttle. Between the front end of the recess
and the sliding piece is inserted a spring which permits of the tongue being drawn
forward or extended towards the nose or tip of the shuttle as required.
A second india rubber or other spring may also when required be employed for
retaining the two portions of the spindle or tongue in its normal position. Suitable
pins or hooks may be provided on the two parts of the tongue or spindle for the
said spring to pass over.
The tongue may or may not be armed with a spring or springs for retaining the
bobbin or cop thereon, and its nose or free end provided with or without a catch
or catches.
Also if desired on the spindle of the shuttle may be mounted an adjustable boss
provided with (or without) a flange for regulating the length of the spindle to that
of the bobbin. In the boss or its flange is provided a recess or aperture through
which the spring, (when a spring is employed) which is employed for retaining the
bobbin on the spindle, passes.
Shuttle spindles constructed as herein described may be raised for the insertion
or withdrawal of the bobbin or cop, and the above described improvements may be
applied, either separately or in combination to shuttles now in use.

page_text: Improvements in or relating to Shuttles for Weaving Woollen,
Worsted, and other Fabrics.
I, WALTER MORTIMER, of Long Row, Horsforth, near Leeds, in the County
of York, Weaving Overlooker, 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 shuttles such as are used iu looms for
weaving woollen, worsted, and other fabrics, and its objects are, first, to provide,
a spindle or tongue capable of being drawn in a longitudinal direction to prevent
sluffing" or breakage of the weft on the bobbin or cop; and, secondly, to
securely retain the spindle or tongue in position within the shuttle during the
weaving operation, and preventing it from rising and thereby damaging the warp
thread.
According to this invention the spindle or tongue upon which the bobbin or cop
is placed is jointed within the shuttle and retained within the same by means of
the ordinary spring. But in order to prevent it rising when the shuttle is at work,
a spring is formed in one or more parts suitably fixed by any convenient means
within the shuttle. The said spring or springs is or are armed with a catch of
any suitable construction arranged to pass across or engage with the top or other
portion of the shank of the tongue for preventing it from rising when the shuttle
is at work.
The tongue of the shuttle is made in one or more parts, that is to say, the
tongue may be made to slide through its shank or heel that is in two separate
pieces connected together by a sliding piece or coupling arranged to slide in
a recess formed in the shank in which may or may not be also cut one or more
grooves to which a sliding piece, in which the end of the tougue is secured -
works. The sliding piece is retained in position when the spindle or tongue is
closed to its working position by the sides of the shuttle. Between the front end
of the recess and the sliding piece is inserted a spring which permits of the
tongue being drawn forward or extended towards the nose or tip of the shuttle as
required.
A second india rubber or other spring may also when required, though not
necessarily so, be employed for retaining the two portions of the spindle or tongue
in its normal position. Suitable pins or hooks may be provided on the two parts
of the tongue or spindle for the said spring to pass over.
The tongue may or may not be armed with a spring or springs for retaining the
bobbin or cop thereon and its nose or free end provided with or without a catch
or catches.
Shuttle spindles constructed as herein described may be raised for the insertion
or withdrawal of the bobbin or cop, and the above described improvements may
be applied, either separately or in combination to shuttles now in use.

page_text: Figs. 12 and 13 are respectively a part side elevation and transverse section of a
spindle constructed according to this invention.
Like parts in all the views are marked with similar letters of reference.
A is the body or shell portion (hereafter termed the shuttle) of the shuttle
which is made of wood tipped with metal and is constructed in the usual shape
and ordinary manner. The spindle or tongue upon which the bobbin or cop is
placed is formed in two parts, namely the shank or heel portion B and the tongue B.
The shank B is jointed at b within the recess in the shuttle A and retained therein
by means of any convenient arrangement of spring, such as C.
But in order to prevent the spindle B rising when the shuttle is at work, a
spring D shaped as shown at Fig. 4 is formed in one or more parts and it is
suitably fixed by any convenient means such as by pin or pins E as shown within
the shuttle A. The said spring or springs D is or are armed as shown at Fig. 4
with a catch F of any suitable construction arranged to pass across or engage with
the top of the shank B of the tongue B¹ for preventing it from rising when the
shuttle is at work.
At Figs. 5 and 6 the catch F is shown in the form of a pin fixed in the side of
the shank B and a hole is formed in the spring D to prevent the tongue from
rising.
At Figs. 7 and 8 the catch F is shown in the form of a block mounted or
sliding upon a horizontal guide or barf and so arranged that its flattened surface
will pass over or slide upon the top of the shank. B and form a stop for preventing
the shank rising. A helical or other spring f' which encircles the guide bar fis
employed for keeping it over the top of the shank.
At Figs. 9 and 10 the catch-block F is arranged to pass under two horizontal
guides ff, semi-circular or other recesses being formed into which the horizontal
guides enter. In this case two springs f¹ is employed for retaining the catch block
in its outward position over the top of the shank B.
At Fig. 11 a circular catch block F is shown mounted or sliding upon a single
horizontal guide f, which is encircled by a helical spring f' for pressing the catch
block into a semi-circular, or other recess formed in the top of the shank B when
it is required to prevent the latter from rising.
The tongue of the shuttle is made in one or more parts, that is to say, the
tongue B' may be made to slide through front end of the shank B,-that is, as
shown in the drawings. The two separate pieces are connected together by a
bifurcated or other sliding piece or coupling G, shaped as shown in transverse
section Fig. 13, arranged to slide in a recess Bx formed in the sbank B. In the
recess B* may when required (though not necessarily so) be also cut one or more
grooves in which a sliding piece G may work, but I prefer to arrange it as shown.
In the tongue is cut one or more, say two, recesses or flats over or in which the
forks of sliding piece G pass for holding the tongue B¹ in a sliding position. The
sliding piece G is retained in position when the tongue B¹ is closed in to its working
position by the sides of the shuttle A. Between the front end of the recess B*
and the sliding piece G is inserted a helical or other spring G* which permits of
the tongue B¹ being extended or drawn forward by the weft towards the nose or
tip A¹ of the shuttle as required, thereby compressing the spring G*. As soon as
the cause of the compression is removed the spring assumes its normal or required
position. The spring G* also aids in retaining the bifurcated sliding piece Gin
position within the recess B* and on the end of the tongue B', as well as provides
for the tongue adjusting itself to the tension of the weft.
A second india-rubber or other spring H, shown in dotted lines at Fig. 12, may
also when required,-though not necessarily so,-be employed for retaining the
two portions, the shank B and tongue B¹ in its normal position.
Suitable pins or hooks H¹ may then be, provided on the two parts, the shank and
the tongue respectively, for the said spring H to pass over.
The tongue B' may, or may not, be armed with a spring or springs I,-one
spring is shown at Fig. 3, and two are shown at Fig. 1, for retaining the bobbin

page_text: or cop thereon, and the nose or free end of the tongue B' may be provided with a
catch or catches b* Fig. 3; or without as shown at Fig. 1.
Also if desired on the tongue B' of the shuttle may be mounted an adjustable
hoss J, shown in dotted lines at Fig. 3, provided with (or without) a flange for
regulating the length of the spindle to that of the bobbin. In the boss or its
flange is provided a recess or aperture through which the spring I, (when a spring
is employed) passes and which is employed for retaining the bobbin on the spindle.
The boss J may be fixed in position by any convenient means such as a set screw.
Shuttle spindles constructed as herein described may be raised for the insertion
or withdrawal of the bobbin or cop, and the above described improvements may
be applied, either separately or in combination to shuttles now in use.
Also should a spring G break it can be readily replaced with another one by
simply sliding the bifurcated piece G out of connection with the tongue B¹ and
drawing the tongue forward until the new spring can be placed in the recess B* in
the shank B. This arrangement of readily releasing and refixing the tongue B'in
position in the shank B also permits of springs G-strong or weak-being readily
changed so as to adapt them to the nature, quality, and character of the yarn,
weft, or cop being used.
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 shuttles for weaving woollen, worsted, and other fabrics the method of
-adjustably fixing the tongue to its shank and the means for preventing them
from rising when at work; consisting of (1) a shank such as B, jointed within the
shuttle, and provided with a recess, such as B*, (2) passing the one end of the
tongue, such as B', through the front end of the shank into the said recess (3) a
sliding piece, such as G and spring such as G* for securing the end of the tongue
in the recess and providing for the tongue adjusting itself to the tension of the weft
and (4) the catch such as F in Figures 1 to 6 or the sliding catch block, such as F
Figures 7 to 11 arranged to engage with the shank for preventing it and the
tongue from rising when the shuttle is at work-all combined and arranged in the
manner and for the purposes herein before described and illustrated.
2. In shuttles for weaving woollen, worsted, and other fabrics the combination of
a shank B jointed in shuttle A, recess B* in said shank, tongue B' one end of which
passes through the front end of the shank into the said recess, bifurcated or other
retaining piece G sliding in the recess, and spring Gx, all arranged as and for the
purposes set forth.
3. In shuttles for weaving woollen, worsted, and other fabrics the application to
and combination of the catch F either in the form of a spring hook or sliding
catch block to shuttle tongues of ordinary construction as and for the purposes
set forth.
