Improvements in Looms.
I, GUSTAV FUNKENBERG of Elberfeld, Laurentiusstrasse 25 Rhenish Prussia
Germany, Merchant do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to make the loom to go easy and light and to
enable the weaver to have a free look over the warp and the shedding, so that he
can work quicker and make more strokes than usual. To attain this the loom is
constructed as shown in the accompanying drawing and as described hereafter.
Figure 1 is a front view of the loom; Figure 2 is a top view of the same;
Figure 3 is a longitudinal section; Figures 4 and 5 show skeleton drawings of the
working mechanism of the leaves.
The frame 1 of the loom is in the example shown supposed to be made of wood,
though it may be of iron, at the back side of the same is arranged the main driving
shaft 2, carrying the pulley 3, from which the power is transmitted on to the
pulley 4 of the shaft 5. From this shaft the batten 9 is worked to and fro by
means of the fly wheel 8, the crank pin 6 and the rod 7. A bevil wheel 10 on
shaft 5 gears into a similar wheel 11 on an oblique shaft 12 and by means of the
bevil gear 13 the shaft 14 is made to turn; perpendicularly below the shaft 14 is
mounted another shaft 15, which is connected to and driven from the shaft 14 by
means of the spur wheels 16 and 17.
Upon the shafts 14 and 15 are keyed the lifting drums or discs 18 and 19
respectively, which are made of various shape according to the binding of the
fabric, which shall be produced.
These drums consist of pairs of excentric discs, which work together and which
are so shaped, that they never touch each other but that the distances between the
circumferences of two corresponding discs are always the same, whatever their
angular position may be-(one disc is always the reciprocal of the other).
Into this constant and open space between two discs I put rollers 21° which are
held at the end of levers 21 having their fulcrums at 24 in the horizontal plane
put centrally between the geometrical axis of the shafts 14 and 15. The other end
of these levers is connected to the lower prolongation 22 of the shafts 23 supporting
the same and these prolongations are also guided in a grate 25 below.
By means of the Figures 3, 4 and 5 it will now be easy to understand how the
lifting and lowering of the leaves and the formation of the shedding is done by
means of the excentric disc drum.
For each particular binding a special combination of discs for the drum is to be
made or the single discs may be exchanged for others.
The excentrics 26 which actuate the levers 27 have for their object to cause a
regular and perfect throw of the shuttle; this arrangement is not new in itself; it
is mentioned here for the sake of giving a complete description; the levers 27 are
guided between vertical bars 28. A cam 30 serves for actuating the regulator 31
and take up arrangement by means of levers and rollers as shown in Figure 2.
The woven fabric is carried between the rollers 32 and over the guide bars 33 on
to the clothbeam 34 which is set in motion by means of a belt 35 from the
regulator; 36 is a bar by means of which the levers 37 and the coupling 38 are
actuated so as to couple the pulley 3 firmly with the shaft 2 or allowing it to turn
freely on the shaft; 39 are brackets carrying the shaft 5.

Improvements in Looms.
I, GUSTAV FUNKENBERG of Elberfeld, Laurentiusstrasse No. 25 Rhenish
Prussia Germany, 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 :-
The object of this invention is to make the loom to go easy and light and to
enable the weaver to have a free look over the warp and the shedding, so that he
can work quicker and make more strokes than usual. To attain this the loom is
constructed as shown in the accompanying drawing and as described hereafter.
Figure 1 is a front view of the loom; Figure 2 is a top view of the same;
Figure 3 is a longitudinal section; Figures 4 and 5 show skeleton drawings of the
working mechanism of the leaves.
The frame 1 of the loom is in the example shown supposed to be made of wood,
though it may be of iron, at the back side of the same is arranged the main driving
shaft 2, carrying the pulley 3, from which the power is transmitted on to the
pulley 4 of the shaft 5. From this shaft the batten 9 is worked to and fro by
means of the fly wheel 8, the crank pin 6 and the rod 7. A bevil wheel 10 on
shaft 5 gears into a similar wheel 11 on an oblique shaft 12 and by means of the
bevil gear 13 the shaft 14 is made to turn; perpendicularly below the shaft 14 is
mounted another shaft 15, which is connected to and driven from the shaft 14 by
means of the spur wheels 16 and 17.
Upon the shafts 14 and 15 are keyed the lifting drums or discs 18 and 19
respectively, which are made of various shape according to the binding of the
fabric, which shall be produced.
These drums consist of pairs of excentric discs, which work together and which
are so shaped, that they never touch each other but that the distance between the
circumferences of two corresponding discs are always the same whatever their
angular position may be-(one disc is always the reciprocal of the other).
Into this constant and open space between two discs I put rollers 21 which are
held at the end of levers 21 having their fulcrums at 24 in the horizontal plane put
centrally between the geometrical axis of the shafts 14 and 15.
The other end of these levers is connected to the lower prolongation 22 of the
shafts 23 supporting the same and these prolongations are also guided in a grate 25
below.
By means of the Figures 3, 4 and 5 it will now be easy to understand how the
lifting and lowering of the leaves and the formation of the shedding is done by
means of the excentric disc drum.
For each particular binding a special combination of discs for the drum is to be
made or the single discs may be exchanged for others. The excentrics 26 which
actuate the leavers 27 have for their object to cause a regular and perfect throw of
the shuttle; this arrangement is not new in itself; it is mentioned here for the
sake of giving a complete description; the levers 27 are guided between vertical
bars 28.
A cam 30 serves for actuating the regulator 31 and take up arrangement by
means of levers and rollers as shown in Figure 2.
The woven fabric is carried between the rollers 32 and over the guide bars 33 on
to the cloth beam 34, which is set in motion by means of a belt 35 from the
regulator; 36 is a bar by means of which the levers 37 and the coupling 38 are
actuated so as to couple the pulley 3 firmly with the shaft 2 or allowing it to turn
freely on the shaft; 39 are brackets carrying the shaft 5,

page_text: 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:
In a loom the leaves 23 having prolongations 22 which are guided in a grate 25
and connected to levers 21 having antifriction rollers 21° at one end, in combination
with drums 18 and 19 that are composed of pairs of excentric discs corresponding
with each other in such a manner that there is always an open space of equal
distance between two corresponding discs in any position of the same and which in
being turned cause the levers 21 to raise and lower the leaves 23.
