Improvements in or connected with Weaving Shuttles.
I, EDMUND SLICER, of 37A, Booth Street, Bradford, in the County of York,
Merchant, do hereby declare the nature of this invention to be as follows:
My invention relates to weaving shuttles.
Weaving shuttles and especially those used for double pick weaving are fre-
quently made of much greater width than height; heretofore in such shuttles,
when used for single pick weaving, the thread carrier has been in the form of a
round bobbin and the amount of thread which can be placed upon such a bobbin
is limited by the height of the shuttle so that considerable spaces are left between
the bobbin and the sides of the shuttle. The object of my invention is to pro-
vide means whereby a much larger amount of thread than heretofore may be
placed in the shuttle so as to obviate the stoppage of the loom so frequently as
is now the case.
According to my invention I use a wood block or centre for carrying the
thread, which block has a shape approximately corresponding with the section
of the shuttle but considerably smaller than the recess in the same, so that
whilst the said block is capable of receiving as many convolutions of thread as
the ordinary bobbin, such convolutions will be of very much greater length,
whereby when the block is fully wound to an extent corresponding with the
height of the shuttle, the thread will extend to the sides of the said shuttle.
I have found in practice that by means of my invention as much as four
times the quantity of thread that it was heretofore possible to place in a shuttle
of a given size can be placed in the said shuttle.
I advantageously provide for varying the tension of the thread as it is drawn
from the shuttle by the use of one or two pairs of pins between which the thread
is passed and which can be turned to a greater or less extent in order to cause
the thread to pass through more or less of an angular course.

Improvements in or connected with Weaving Shuttles,
I, EDMUND SLICER, of 37A, Booth Street, Bradford, in the County of York,
Merchant, 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:-

page_text: Weaving shuttles and especially those used for double pick weaving are fre-
quently made of much greater width than height; heretofore in such shuttles,
when used for single pick weaving, the thread carrier has been in the form of a
round bobbin and the amount of thread which can be placed upon such a bobbin
is limited by the height of the shuttle so that considerable spaces are left between
the bobbin and the sides of the shuttle. The object of my invention is to pro-
vide means whereby a much larger amount of thread than heretofore may be
placed in the shuttle so as to obviate the stoppage of the loom so frequently as
is now the case.
According to my invention I use a block or centre of wood or other suitable
material for carrying the thread, which block has a shape approximately corre-
sponding with the section of the shuttle but considerably smaller than the recess
in the same the shape of which in cross section also approximately corresponds
with the cross section of the shuttle.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which:-
Figure 1 is a plan view of a shuttle having my improvements applied to it:
Figure 2 is a section on the line 2--2 of Figure 1; and
Figure 3 is an end view of the block or bobbin of the shuttle upon which the
thread is wound:
Figure 4 is an elevation of the tension device.
a is the body of the shuttle which is of ordinary construction except that the
recess in the same for receiving the bobbin is cut out so that it has practically
the same shape as the exterior of the shuttle in cross section and b is the hinged
peg for carrying the bobbin or block.
c is my improved bobbin or block upon which the thread is wound the said
block having that part upon which the thread is wound made of a section
approximately corresponding with the section of the shuttle, for instance as
clearly indicated in section in Figure 2 and in dotted lines in Figure 3. The
flange d on the end of this block c is as shewn provided with a slot which
when the block is fully wound to an extent corresponding with the height of
or lugupon the shuttle in order to retain the said block stationary relatively
with the shuttle; it is to be understood, however, that any other suitable means
may be provided for holding the said block.
With the construction herein before described it will be understood that whilst
the said block is capable of receiving as many convolutions of thread as the
ordinary bobbin such convolutions will be of very much greater length, whereby
when the block is fully wound to an extent corresponding with the height of
the shuttle, the thread will extend to the sides of the said shuttle as shewn in
Figure 2.
I have found in practice that by means of my invention a shuttle of a given
size will carry as much as four times the quantity of thread that it has hereto-
fore been possible to carry in the said shuttle with the usual bobbin.
I advantageously combine with a shuttle having my improved block or bobbin
applied to it an eye g or the like for varying the tension of the thread as it is
drawn from the shuttle, this device as shewn consists of an eye through which the
thread is passed and which can be turned to place the said eye more or less at
an angle to the thread in order to cause the said thread as it is drawn from the
bobbin to assume an angular position as it passes through the eye and so pro-
duce more or less friction between the said thread and the eye.
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. A weaver's shuttle having a recess for receiving the thread of a shape in
cross section approximately corresponding with the cross sectional shape of the
exterior of the shuttle, in combination with a block or bobbin having that

page_text: portion upon which the thread is wound also of a shape approximately corre-
sponding with the cross sectional shape of the recess, substantially as, and for
the purpose described.
2. In a weaver's shuttle a recess for containing the bobbin of a cross sectional
shape approximately corresponding with that of the exterior of the shuttle in
cross section, a hinged pin for carrying the block or bobbin, a block or bobbin
upon the said pin having that part upon which the thread is wound of a cross
sectional shape approximately corresponding with that of the recess in the
shuttle, a flange on the end of the said block or bobbin, a slot in the said flange
and a pin on the shuttle for entering the said slot all substantially as, and for
the purpose, described.
3. The combination with a weaver's shuttle having the block or bobbin carry-
ing the thread of approximately the same shape in cross section as the shuttle,
of an eye through which the thread passes as it is drawn from the bobbin the
said eye being capable of rotation in order to produce more or less tension upon
the thread, substantially as described.
