A Method of and Means for Avoiding Waste of Thread or Yarn in
Shuttle Bobbins.
I, FRANZ LOUIS WÄCHTLER, of No. 48, Süchtenelerstrasse, Dülken, near
München, Gladbach, Rhineland, in the German Empire, Director, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:
6
This invention relates to shuttles and bobbins for looms and to a method for
working the same, so as to save the waste of the thread. or yarn rests" of the.
bobbins or cops, and to allow the whole of the thread or yarn on the bobbins and
cops being used up, which is not possible with the bobbins and method. used.
hitherto.
In order that this invention may be the better understood, I now proceed to..
describe the same reference being had to. the accompanying drawings and to the
letters and figures marked thereon in which like letters refer to like parts in
the various figures.
- Figures 1, 2 and 3 illustrate the reel constructed of two parts on which the
thread or yarn is wound.
Figures 4 and 5 illustrate parts of the bobbin holder.
Figure is a plan of the shuttle."
Figure 7 is a part sectional side view according to the line BC Figure 6.
Figure 8 is a sectional transverse view through the shuttle on the line AB
Figure 6.
The shuttle is somewhat longer than those in use at present, otherwise its form
is the same as in ordinary use. The improvement consists in the construction of
the reel, which consists of an inner and of a shorter outer part, in the method of
using such reel to avoid waste of rests of bobbins or cops and in the adaption of
the shuttle therefor.
The reel on which the thread or yarn is wound is constructed of a short slotter
outer tube 1,. Figure 1, having a turned up end or rim, and of an inner tube 2.
Figure 2 slotted at the part marked X. The divided parts of the tube 2 formed
by the slot may be pressed together when the outer tube 1 is placed over the
inner tube shown in Figure 3. The outer tube 1 when apart can be held in the
holder 4 in the bobbin, which has a spring 3. When on the inner tube 2 it can
be held on a known bobbin spindle 5. When winding the thread or varn on reel,
the commencement of the thread, a must be placed in the slot of the rim as
shown in Figure 3. When the bobbin is completed it is placed on the bobbin
spindle 5 Figure 7, in the usual manner. When the bobbin has been used in
the usual manner except the rest (Figure 6) the tube 2 is removed from the outer
tube 1, the latter carrying the rest of the thread or yarn which has been con-
sidered waste hitherto, is placed on the holder 4, Figure 7. The end a is now
tied to the end b of a newly inserted bobbin. When the shuttle has been inserted
into the loom the rest on the tube 1 is used first and then without interruption

page_text: the thread or yarn of the new bobbin, except the rest of the latter. When the rest
marked c has been used the thread takes the shortest route and passes through the
middle of the tube 1 see Figure 6.
It will be obvious that the form of the bobbin holders &c. may vary the prin-
cipal point is that the rest on the rear of the bobbin is placed in front of the new
bobbin and that the end of such rest is tied to the thread of the new bobbin,
without removing the thread from the eye or hole 6 and without threading the
thread afresh through the latter. Thus before inserting a new bobbin the slotted
tube 1, on the holder 4 (Figure 6) is removed from the shuttle; the rest of the
last used bobbin is taken off the spindle 5 and placed on the holder 4; then the
end a of the last rest is tied to the thread of the new bobbin.
It is immaterial how much the rest is, which is placed in front of the new
bobbin, the point is that there is no thread or yarn left on the tube 1 to be
removed.
"
When using cops from which the thread or yarn winds from the inside, a
slotted bridge may be arranged, if desired, instead of the holder 4, to separate
the con carrying the "rest" from the new cop. However, this is not absolutely neces-
sary the important arrangement is that the "rest" on the cop shall be between
the exit hole of the shuttle and the new cop, and that the remaining end of the
old cop, shall be tied to the starting end of the new cop, and further that the
shuttle is of suitable length to accommodate the rest bobbin or cop, to be placed
in front of the new bobbin or cop.
Instead of the elastic inner tubes shown, tubes of paper may be used: and
instead of making the outer tube of sheet metal which is assumed in the draw-
ings; it may be made of wood or other suitable material. The means and method
herein before described may be used in ordinary looms, as well as in any other
machine having shuttles or the like, for instance in ribbon looms &c.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1st. A method for using up the "rests" or waste on bobbins, cops and the like,
in which such bobbins or cops carrying the "rest" are placed in front of the fresh
material in the shuttle, and the "rest" tied to the fresh ntaterial so as to use the
same up without interruption.
2nd. A shuttle of suitable length adapted to the method claimed in Claim 1,
and reels or similar devices of suitable construction adapted to be shortened.
