PROVISIONAL SPECIFICATION.
Improvements in or relating to Cop Shuttles.
I, JOHN IRELAND, of Ireland's Laue, Dundee, in the County of Forfar,
Scotland, Shuttle. and Machine Maker, do hereby declare the nature of this
invention to be as follows:-
This invention which relates to improvements in loom shuttles used in weaving
operatione, has for its object the better regulation of the tension of the thread.
In carrying out my invention according to one modification, I introduce a spring
beneath a T tension device or drag in order to give it elasticity, such drag being
in this manner held against a pin with sufficient force to give the required tension.
The pressure of such spring is regulated by a screw. The drag may be made of
steel or of any other suitable material. The pin is made preferably of iron or steel
and the thread exit hole of porcelain. The woodwork of the shuttle is so fashioned
that a portion is left, forming a bridge in which is a holo through which the thread
from the cop is led toward the drag. The tension is determined by the force with
which the spring presses the T tension device or drag against the pin.
The T tension device or drag is provided with projections so disposed that the
tendency of the thread to pass over the eud of, and under such tension, may be
obviated.
In another modification the T tension device or drag is formed as a spring, such
spring being pressed by another, the combination acting much as in my first
modification.
In a third modification the spring is not used, but the spring of the tension
device or drag bears against a pin, such pin being so situated that the T tension
device or drag bears with sufficient force against the pin to give the necessary
tension. It is to be noted that in all these shuttles there is a slot through the
bottom for the purpose of allowing the caddis to pass away.

Improvements in or relating to Cop Shuttles.
1, JOHN IRELAND, of Ireland's Lane, Dundee, in the County of Forfar,
Scotland, Shuttle and Machine 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 which relates to improvements in loom shuttles used in weaving
operations, has for its object the better regulation of the tension of the thread.
And in order that my said invention and the mauner of performing and carrying
the same into effect or practice may be properly understood, I have horeunto
appended two explanatory sheets of drawings in which the same reference letters
are used to indicate corresponding parts in all the figures where shown.
Figure 1. (Sheet 1.) is a plan of a shuttle with catch nud part of spring cover

page_text: removed to more clearly show my improvements, and Figure 2. is a longitudinal
section at X. Y. (Figure 1.) of same.
Figures 3. 4. 5. and 6. (Sheet 2.) are similar respective part views of a shuttle
showing two other modifications, while
Figure 7. is a cross-section at V. W. (Figure 6.) while looking in the direction
of the arrow A.
Figures 8. to 13. are detached views of details drawn to a larger scale.
In carrying out my invention according to one modification as illustrated by
Figures 1. 2. 7. 8. 9. 10. and 11. I introduce a spring 20. beneath a T tension
device or drag 21. in order to give it elasticity, such drag being in this manner
held against a pin 22. with sufficient force to give the required tension. The
pressure of such spring is regulated by a screw 19. The drag may be made of
steel or of any other suitable material. The pin 22. is made preferably of iron or
steel and the thread exit hole 23. of porcelain. The woodwork of the shuttle is 80
fashioned that a portion 24. is left, forming a bridge in which is a hole 25. through
which the thread from the cop is led toward the drag. The tension is determined
by the force with which the spring 20. presses the T. tension device 21. against
the pin 22. The T tension device or drag is provided with projections 30. so
disposed that the tendency of the thread to pass over the end of and under such
Ttension may be obviated.
In another modification, as illustrated by Figures 3. 4. 7. 12. and 13. the
Ttension device 20. is formed as a spring, such spring 28. being pressed by
another 20, the combination acting much as in my first modification.
In a third modification, as illustrated by Figures 5. 6. 12. and 13. the spring 20.
is not used but the spring 28. of the T tension 26. bears against a pin 27, such pin
being so situated that the T tension device bears with sufficient force against the
pin 22. to give the necessary tension.
It is to be noted that in all these shuttles there is a slot 29. through the bottom
for the purpose of allowing the caddis to pass away.
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 loom shuttles, the construction, combination and arrangement of parts
consisting essentially of the screw 19. the spring 20, T tension device or drag 21,
pin 22, thread exit hole 23, bridge 24, and hole 25, substantially as heroin described
in reference to and shown in the annexed drawinga.
(2) In loom shuttles, the construction, combination and arrangement of parts
consisting essentially of the screw 19, the spring 20, spring tension device or
drag 26, pin 22, thread exit hole 23, bridge 24, and hole 25, substantially as herein
described in reference to and shown in the annexed drawings.
(3) In oom shuttles, the construction, combination and arrangement of parts,
consisting essentially of the spring tension device or drag 26, pin 22, thread exit
hole 23, bridge 24, hole 25, and pin 27, substantially as herein described in reference
to and shown in the annexed drawings.
(4) In loom shuttles, the mode of inserting drags from below by leaving the
bridge solid with a guide hole through which the thread passes from the cop to the
tension, substantially as described.
(5) In loom shuttles, the use of the T tension device or drag (Figures 10. and 11.)
as described.
(6) In loom shuttles, the use of the spring T tension device or drag (Figures 12
and 13.) as described.
