Improvements in Ribbon Looms.
I, PETER VOM STEIN, 10 Louisenstrasse Barmen in the Province of Rhenish Prussia
Ribbon Manufacturer do hereby declare the nature of my said invention to be as
follows:-
My invention has for its object, Improvements in Ribbon Looms by which when
one of the small quills or bobbins bearing the shute is empty I am enabled to stop it
for refilling without stopping the whole of the loom which has hitherto been necessary
so, that by my improvements the loom is kept constantly at work and a great saving
of time and money is effected.
In my improvements the batton of the loom consists of two parts, one part being
stationary the other being made so as to have a vertical movement. This moveable
part of the batton carries two shuttles with the quills one above the other, the operating
mechanism of which is arranged as hereafter described so that one only of these
shuttles can work at one time. This is effected by a cog wheel which engages with
a toothed rack on the shuttle and is connected by a shaft with a second cog wheel
operated by the driving rack or bar. That part of the batton which contains the
shuttles is supported by a spring and is made to fall by means of a chain and pulley
operated by the weaver in charge so that when the bottom shuttle is empty it may
be disengaged from the operating cog, and the upper one may be lowered so as to
engage in its place, and when this is in turn empty the release of the chain by the
weaver will allow the spring to raise the batton to a position in which the bottom
shuttle is engaged with the operating cog. By this means the one shuttle when
empty is stopped and may be refilled without stopping the whole of the loom..
The shuttle consists
The putting in of new quills is done in the following manner.
of two parts one part bearing the quill being easily removed and replaced in a manner
similar to some shuttles now in use. As soon as a shuttle is set out of work and in
consequence stopped the front part of the shuttle is taken off and a fresh quill put
in it afterwards being again fixed on the back part. The moveable part of the batton
can never fall or rise until the working shuttle is exactly in place that is to say as
soon as the shuttle has reached the end of its course it rests a moment but as the
weaver is not able to operate the chain in the short time available when the shuttle
rests a bar or rack is provided having a catch which every time the rack comes to
the end of its course and the shuttle also has reached the end of its course noves the
end of a little iron bar. The other end of this bar holds back the moveable part of
the batton from falling or rising up by means of two catches so that only when the
end of this catch is moved can the moveable part of the batton be raised or lowered.
The weaver may draw the chain or let it go when he likes so that the moveable part
of the batton can only rise or fall, when the right moment comes and the shuttle is
exactly in its right position. This bar is connected with a spring which always brings
the bar to its position again.
To secure the exact vertical lifting or falling of the moveable part of the batton two
iron pins are provided which enter, corresponding holes in the moveable part of the
batton. These pins also penetrate the shuttles. By means of the employment of two
shuttles for one space in combination with the vertical movement of a part of the
batton by a spring or other means I am enabled to bring a full quill into work without
stopping the loom. The motion obtained whether by the driving rack or bar as
described or with cogs by a peg motion or fly shot motion is similar to those commonly
used in present machines.

Improvements in Ribbon Looms.
I, PETER VOM STEIN of 10 Louisenstrasse Barmen in the Province of Rhenish
Prussia Ribbon Manufacturer de 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 :-
My invention has for its object improvements in ribbon looms by which when one
of the small quills or bobbins bearing the shute is empty I am enabled to stop it for
refilling without stopping the whole of the loom which has hitherto been necessary
so that by my improvements the loom is kept constantly at work and a great saving
of time and money is effected.
In my improvements the batton of the loom consists of two parts one part being
stationary and the other being made so as to have a vertical movement. This removable
part of the batton carries two shuttles with the quills one above the other the operating
mechanism of which is arranged as hereafter described so that one only of these
shuttles can work at one time. This is effected by a cog wheel which engages with
a toothed rack on the shuttle and is connected by a shaft with a second cog wheel
operated by the driving rack or bar. That part of the batton which contains the
shuttles is supported by a spring and is made to fall by means of a chain and pulley
operated by the weaver in charge so that when the bottom shuttle is empty it may
be disengaged from the operating cog, and the upper one may be lowered so as to
engage in its place, and when this is in turn empty the release of the chain by the
weaver will allow the spring to raise the batton to a position in which the bottom
shuttle is engaged with the operating cog. By this means the one shuttle
when empty is stopped and may be refilled without stopping the whole of the
loom.
The putting in of new quills is done in the following manner.
The shuttle consists
of two parts one part bearing the quill being easily removed and replaced in a manner
similar to some shuttles now in use. As soon as a shuttle is set out of work and in
consequence stopped the front part of the shuttle is taken off and a fresh quill put
in it afterwards being again fixed on the back part. The movable part of the batton
can never fall or rise until the working shuttle is exactly in place that is to say as
soon as the shuttle has reached the end of its course it rests a moment but as the
weaver is not able to operate the chain in the short time available when the shuttle
rests a bar or rack is provided having a catch which every time the rack comes to the
end of its course and the shuttle also has reached the end of its course moves the end
of a little iron bar. The other end of this har holds back the movable part of the
batton from falling or rising up by means of two catches so that only when the end of
this catch is moved can the removable part of the batton be raised or lowered. The
weaver may draw the chain or let it go when he likes so that the movable part of
the batton can only rise or fall when the right moment comes and the shuttle is exactly
in its right position. This bar is connected with a spring which always brings the
bar to its position again.
To secure the exact vertical lifting or falling of the movable part of the batton
two iron pins are provided which enter corresponding holes in the movable part of
the batton. These pins also penetrate the shuttles. By means of the employment
of two shuttles for one space in combination with the vertical movement of a part of
the batton by a spring or other means I am enabled to bring a full quill into work
without stopping the loom. The motion obtained whether by the driving rack or
bar as described or with cogs by a peg motion or fly shot motion is similar to those
commonly used in present machines.
In order that my invention may be clearly understood and more easily carried
into practice I have appended a sheet of drawings upon which I have fully illustrated
my improvements which will enable any practical person to adapt them under altered
conditions.

Figure 4 is a plan of the shuttles and racks and also shews the catch arrange-
ment M when engaging with the movable part A of the batton.
Figure 5 is a plan of the catch arrangement M when disengaged from the movable
part A of the batton.
Figure 6 is a side, view of the movable part A of the batton shewing a modification
in the arrangement for securing the movable portion of the batton when down.
Figure 7 is a similar section to Figure 6 but shewing the movable portion A of the
batton when up.
In my improvements the batton of the loom consists of two parts A and A¹ the
part A¹ being stationary and the other A being made so as to have a vertical move-
ment and provided to each pair of shuttles. This moveable part A of the batton
carries the two shuttles B and B with the quills one above the other the operating
mechanism of which is arranged as hereafter described so that one only of these
shuttles can work at one time. This is effected by the cog wheels E which engage
with the toothed rack and on the shuttles B and B and is connected by the
shaft d' with second cog wheels D which are operated by the driving rack or bar F.
The part A of the batton which contains the shuttles is supported by the spring H
and is made to fall by means of the chain and pulleys and h³ operated by the
weaver in charge so that when the bottom shuttle B is empty it may be disengaged
from the operating cogs E and the upper one B may be lowered so as to engage in
its place and when this is in turn empty the release of the chain h' by the weaver
will allow the spring to raise the batton A to a position in which the bottom
shuttle B is engaged with the operating cogs E. By this means the one shuttle
when empty is stopped and may be refilled without stopping the whole of the loom.
The shuttle consists
The putting in of new quills is done in the following manner.
of two parts B and 6 the one part 6 bearing the quill being easily removed and
replaced in a manner similar to some shuttles now in use. As soon as the shuttle is
set out of work and in consequence stopped the front part 6 of the shuttle is taken
off and a fresh quill having been put in, it is afterwards again fixed on the back
part B.
The moveable part A of the batton can never fall or rise until the working
shuttle B or B' is exactly in place that is to say as soon as the shuttle has reached
the end of its course as shown by Figure 2 it rests a moment but as the weaver is
not able to operate the chain ' in the short time available when the shuttle rests the
bar or rack F is provided with the catch m¹ so that every time the rack comes to the
end of its course and the shuttle also has reached the end of its course the said rack
moves the end of the pivoted lever M the other end of which prevents the moveable
part of the batton from falling or rising up by means of the two catches n¹ and n³
being engaged by the end m³ of the lever so that only when this catch m¹ is moved
can the moveable part A of the batton be raised or lowered. The weaver may draw
the chain H or let it go when he likes but the moveable part A of the batton can
only rise or fall when the right moment arrives and the shuttle B or B' is exactly
in its right position. The lever M is connected with the spring m³ which always
causes it to take the position shown in figure 4.
Figure 5 showing the position of the lover M when moved by the catch m².
To secure the exact vertical lifting or falling of the moveable part of the batton
two iron pins O are provided which enter corresponding holes in the moveable
part A of the batton and also penetrate the shuttles. It is not absolutely necessary
to use the chain H for in some cases the weavers may prefer to do work without it
in the following manner. A catch P in combination with the spring p' is fixed on
the stationary part A of the batton just over the top of the moveable part A of the
batton when put down thereby preventing it from rising, the releasing of the catch P
having the same effect as the releasing of the chain. In order to lower the movable
part A of the batton a skilful weaver will be able to press it down by his hand when

page_text: the right moment arrives in which position it is retained by the catch Pas shown in
Figure 6.
As the racks and 63 of the shuttles when rising or falling may not be in the
exact position to engage with the teeth of the cog wheels E I round the edges of the
teeth of the cog wheels E both top and bottom so that they may slip into the teeth of
the racks 6 and 6 as the case may be. By means of the employment of the two
shuttles B and B₁ for one space in combination with the vertical movement of the
part A of the batton separately for each space which vertical movement is regulated
by the catch m' upon the driving rack F the shuttles being operated by the. cog
wheels E having rounded edges I am enabled to bring a full quill into work without
stopping the loom. The main motion obtained whether by the driving rack or bar
as described or with cogs or by a peg motion or fly shot motion is similar to those
commonly used in present machines.
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 :-
1st. In improvements in ribbon looms the use of two shuttles for one space in
combination with the vertical movement of the part A of the batton substantially as
and for the purpose herein set forth & shewn upon the drawings.
2nd. In improvements in ribbon looms the mode of and means for regulating the
time of the rise & fall of the movable part A. of the batton substantially as & for the
purpose herein set forth and shewn upon the drawings.
3rd. In improvements in ribbon looms the means of raising or lowering the
moveable part A of the batton substantially as & for the purpose herein set forth &
shewn upon the drawings:
4th. The improvements in ribbon looms substantially as & for the purpose herein
set forth & shewn upon the drawings.
