FRIEDRICH CARL GLASER of Berlin in the Kingdom of Prussia and Empire of
Germany Engineer and Patent-Solicitor "A NEW OR IMPROVED MACHINE FOR
THE MANUFACTURE OF GIMP" [communicated to him by Carl Ludwig Hohl a
person residing at Dresden in the Kingdom of Saxony and German Empire]
This invention relates to a new machine for the manufacture of looped gimps,
which heretofore has always been made by hand. The machine makes simul-
taneously two principal motions, of which one serves to form the loop or bow, and
the other to interlace the binding cord &c, so as to produce the 'gimp.
Fig. 1 of the accompanying drawings shows an elevation and Fig. 2 an end view
of the machine. a and b are two opposite shuttle boxes, in which a shuttle is
moved to and fro by means of the levers e and f actuated by the cam groove
cylinder g. The levers enter for this purpose slots (Fig. 2) in the shuttle boxes so
as to propel the shuttle first in one and then in the opposite direction. A peculiarly
formed arm Fig. 2, turning on the axis i, is periodically moved in between the
two shuttle boxes, close against the box a, and is drawn back again by spring
action. Another arm is situated opposite / on the other side of the shuttle boxes,
and is also, at a certain time, brought between the shuttle boxes. While the arms k
and are moving towards the shuttle boxes, the lower end of the lever is caused by
the cam cylinder g to move into the shuttle box band to move back again as soon
as the arms kl have resumed their position of rest.
The binding thread x is delivered from the shuttle, while the chain or warp
thread or cord y, which passes through an opening of tlie arm 1 is wound off from
a reel underneath the table, and is held stretched by a tension device. The
formation of the binding loops which has hitherto been effected by hand, is effected
by this machine as follows. The shuttle is in the box a (Figs 12 Sheet II) and the
binding thread passes round the projection k¹ of the arm k to the loop just completed,
the two arms and ke being already in their backward position. The arm is now
moved forward between the boxes a and b (Fig. 13) and immediately afterwards the
Duine 10.31

page_text: shuttle is moved over from box a to box b, and consequently between arm land the
warp thread y (Fig. 14). The binding thread x has thus been laid round the warp
thread y as shewn at Fig. 15, where the arm has already receded to its original
position. The shuttle with the binding thread being situated in b, is now led by
the levers e and f back through the loop into the box a (Fig. 16) thereby completing
the loop. After the loop is thus formed, the arm k moves forward between the
shuttle boxes (Fig. 17) whereby the binding thread x is made to slide off the
projection and the loop is then pushed up to the preceding one by means of a
wire m actuated by a crank as shewn at Fig. 1. On the arm k receding, the
projection k³ seizes the binding thread again and draws it back, whereupon the
*formation of a fresh loop commences.
For introducing the gimp material or cords into the above described loops, for
producing the said looped gimps, the following arrangement is employed. The
said gimp materials are wound upon reels attached to rods n n¹ that have loops for
guiding the threads, and that are attached to a horizontal cross piece o that receives
a to and fro motion by any suitable means, such as by a crank with a pin that
moves two slides to and fro that are connected by wires to the piece o, as shewn
on the drawing, so that the rods n n' are at one time situated in front of the box a,
and at another time in front of b. In order to effect the laying of the gimp
material into loops or bows by the to and fro motion of the cord carriers n n¹
needles p² p² p³ p₁ are provided, of which p¹ and p³ have a groove, as at Fig. 9,
while p and p are simply pointed, as at Fig. 8.
At Fig. 6 the needles p³ p³ p' are shewn inserted in completed loops, and a new
loop is formed by the forward motion of the cord carriers n n¹ Fig. 1 from left to
right, that is, from the box a to b, the cords being laid round the needle p¹. After
this loop has been bound in by the thread x in the described manner, another loop
is formed by moving the cord carrier from right to left. In order to free the
needle på for forming this new loop, the needle p' is drawn out of its loop, the lever
carrying it being turned round its pivot, whereupon p' drops with its point into
the groove of the needle p³ as at Fig. 7, and takes up the loop from this needle.
ps is then also drawn back and falls with its point deeper in the vertical slot,
whereupon it is free to form a new loop. In the same way pland p³ are disengaged.
The withdrawal of the needles from the loops is effected by means of an endless
chain r, which travels upon two rollers and turns the needle arms, Figs. 10 and 11,
at the right moment. The forward motion of the needles is effected by springs.
The wire m for pushing up the loop, as also the mechanism for moving the cord
carriers and the needles, can be arranged either at the right hand or at the left
hand of the machine, as shewn at Figs. 1 and 1*. In order to introduce pearls or
beads between the separato loops of the gimp an arrangement is employed as shewn
at Fig. 3. The arm is split at its lower end and leads, in addition to the warp
thread, a thread with beads which is unwound from a roller. The slit of the arm l
can be made wide or narrow, according as one, two, or more beads are to be
introduced. A brush t actuated by an eccentric or tappet, slides over the bead
thread, and thus causes the slit of the arm to be always supplied with beads.
Before a new loop is formed, a wire u, actuated by an eccentric, pushes the beads
out of the slit of the arm up the bead thread, where they are held by the forming
of the loop. If the beads are not to lie one behind the other, but by the side of
each other in the gimp loops, as many bead threads are introduced as beads are
required to lie beside each other. If only beads are to be introduced, the cord
carriers n n run empty.
According as the cords and beads are passed through the warp and binding
threads, various patterns can be produced. For example cord carriers can be
arranged on both sides of the machine, which cross in their motion, so as to lay
the cords across each other, whereupon they are bound together by the binding
thread as described.

the said Friedrich Carl Glaser in the Patent Office on the 21st May 1884.
FRIEDRICH CARL GLASER of Berlin in the Kingdom of Prussia and Empire of
Germany, Engineer and Patent Solicitor. " A NEW OR IMPROVED MACHINE FOR
THE MANUFACTURE OF GIMP." A communication to me by Carl Ludwig Hohl a
person residing at Dresden in the Kingdom of Saxony and German Empire.
This invention relates to a new machine for the manufacture of looped gimp which
heretofore has always been made by hand. The machine makes simultaneously two
principal motions, of which one serves to form the loop or bow and the other to
interlace the binding cord &c, so as to produce the gimp trimming.
Fig. 1 of the accompanying drawings shews an elevation and fig. 2 an end view
of the machine. a and b are two opposite shuttle boxes in which a shuttle is
moved to and fro by means of the levers e and f, actuated by the cam groove
cylinder g The levers enter for this purpose slots (fig. 2) in the shuttle boxes so
as to propel the shuttle first in one direction and then in the opposite direction.
A peculiarly formed arm k, fig. 2, turning on the axis i is periodically moved in
between the two shuttle boxes, close against the box a, and is drawn back again by
spring action. Another arm is situated opposite le on the other side of the shuttle
boxes and is also at a certain time, brought between the shuttle boxes. While the
arms k and are moving towards the shuttle boxes, the lower end of the lever is
caused by the cam cylinder g to move into the shuttle box b and to move back
again as soon as the arms kl have resumed their position of rest.
The binding thread x is delivered from the shuttle, while the chain or warp
thread or cordy, which passes through an opening of the arm is wound off from a
reel underneath the table, and is held stretched by a tension device. The formation
of the binding loops which has hitherto been effected by band, is effected by this
machine as follows: The shuttle is in the box a (figs 12, 13, Sheet II) and the
binding thread passes round the projection ¹ of the arm k to the loop just
completed, the two arms and ke being already in their backward position. The
arm is now moved forward between the boxes a and b (fig. 13), and immediately
afterwards, the shuttle is moved over from box a to box b and consequently
between arm 7 and the warp thread y (fig 14) The binding thread has thus been
laid round the warp thread y as shewn at fig. 15, where the arm has already
receded to its original position. The shuttle with the binding thread being
situated in b, is now led by the levers e and f back through the loop into the
box a (fig. 16) thereby completing the loop. After the loop is thus formed, the
arm k moves forward between the shuttle boxes (fig 17) whereby the binding
thread is made to slide off the projection ¹ and the loop is then pushed up to the
preceding one by means of a wire m actuated by a crank, as shewn at fig. 1. On
the arm h receding, the projection k¹ seizes the binding thread again and draws it
back, whereupon the formation of a fresh loop commences.
For introducing the gimp material or cords into the above described loops, for
producing the said looped gimps, the following arrangement is employed. The said
gimp materials are wound upon reels attached to rods n n¹, that have loops for
guiding the threads, and that are attached to a horizontal cross piece o that receives
a to and fro motion by any suitable means, such as by a crank with a pin that
moves two slides to and fro that are connected by wires to piece o, as shewn on
the drawing, so that the rods n n¹ are at one time situated in front of the box a,
and at another time in front of b. In order to effect the laying of the gimp
material into loops or bows by the two and fro motion of the cord carriers n n¹
needles p¹ p p p are provided of which p¹ and p³ have a groove as at fig. 9, while
p and p are simply pointed, as at fig. 8,

page_text: After
At fig: 6 the needles p³ p³ p* are shewn inserted in completed loops, and a new
loop is formed by the forward motion of the cord carriers n n¹, fig 1, from left to
right that is from the box a to b, the cords being laid round the needle p¹.
this loop has been bound in by the thread x in the described manner, another loop
is formed by moving the cord carriers from right to left. In order to free the
needle p³ for forming this new loop, the needle p is drawn out of its loop, the
lever carrying it being turned round its pivot, whereupon, 2 drops with its point
into the groove of the needle p³ as at fig. 7, and takes up the loop from this
needle. p is then also drawn back and falls with its point deeper in the vertical
slot, whereupon it is free to form a new loop. In the same way p¹ and p² are
disengaged. The withdrawal of the needles from the loops is effected by means of
an endless chain 7, which travels upon two rollers and turns the needle arms,
fig 10 and 11, at the right moment. The forward motion of the needles is effected
by springs. The wire m for pushing up the loop, as also the mechanism for
moving the cord carriers and the needles, can be arranged either at the right hand
or at the left hand of the machine, as shewn at figs 1 and 1ª In order to introduce
pearls or beads between the separate loops of the gimp, an arrangement is employed
as shewn at fig. 3. The arm is split at its lower end and leads, in addition to
the warp thread, a thread with beads which is unwound from a roller. The slit
of the arm can be made wide or narrow, according as one, two or more beads are
to be introduced. A brush t actuated by an eccentric or tappet, slides over the
bead threads and thus causes the slit of the arm to be always supplied with beads.
Before a new loop is formed, a wire u, actuated by an eccentric, pushes the beads
out of the slit of the arms up the bead thread where they are held by the forming
of the loop. If the beads are not to lie one behind the other, but by the side of
each other in the gimp loops, as many bead threads are introduced as beads are
required to lie beside each other. If only beads are to be introduced, the cord
tcarriers n n¹ run empty.
Figs 19 to 22 shew another modification of the apparatus for introducing beads
into the gimp trimmings. Fig. 19 shews the arm that guides the warp thread
and the bead thread, and which is pivotted at g. The position shewn in full lines
is the rest position, while the dotted lines shew the working position. The arm l
is looped at h and carries a second arm b passing through it and provided with a
broad or shovel shaped end i fitting in a recess in the lower part of the arm l, so
that it is flush with the latter. The thread with the beads is led over a small
roller x so as always to be held in the same position, and passes at k, through the
lower part of the arm 1, leading one or more beads up to the plate m, the number
of beads being varied at will, according to the position of the plate m, which is
adjustable, and is mounted on a hinge and held by a spring, so that if one of the
beads should be of excessive size, the plate can yield, so as to make room for it.
If the arm be moved towards the shuttle box, the warp-thread and bead thread
pass down the slots made in the arm from the openings for the beads backwards,
and thence into corresponding slots slots in the shovel, so that the requisite number
of beads that have been raised, will now be situated upon the shovel. The arm?
being still made to advance, a fixed stop n behind which the upper end of the arm b
is situated, causes this to be drawn downwards, and consequently the shovel to be
raised upwards, so as to push the beads situated upon it up the bead thread.
When the parts are in this position, the shuttle carrying the binding thread is
The arm
thrown across between the two arms into the opposite shuttle-box.
then returns to its rest position, while, at the same time the arm b, being released
by the stop n, is also drawn by the spring o back into its original position, with
its shovel in the recess of b. The beads raised by the shovel are entwined by the
loop gimp formed below them, as in the first described arrangement.
Fig. 20 shews the before described apparatus in the rest position, two beads
being situated under the plate m; fig. 21 shews the arm advanced so that the
warp thread and bead thread are situated in the slots of the shovel, with the two
beads situated above the latter, the upper end of b being brought against the

page_text: stops n; fig 22 shews the arm advanced between the shuttle boxes, with the shovel
and the beads thereon raised by the action of the stop, so that the shuttle can pass
beneath the same.
Having thus described the nature of this invention and in what manner the
same is to be performed, as communicated to me by my correspondent, I claim :-
First: The construction of machinery for the manufacture of looped gimps or
gimp trimmings wherein two main distinct operations are performed, namely-
firstly the formation of the binding loops by the combined action of the roller g,
levers ef, shuttle boxes a b, shuttle c, arms k 1, and wire m, and secondly, the
formation of the gimp loops by the combined action of the guide rods n n¹ and
needles p p p p, actuated by the endless chain 7 substantially as herein
described.
Second: The use, in combination with machinery for the manufacture of looped
gimps, of apparatus for the introduction of beads into the loops, wherein a certain
number of beads are first separated from others on a bead thread by a forked arm,
and are then raised up by a second arm or wire in order to be introduced into the
gimp trimming, substantially as herein described.
In Witness whereof, I the said Friedrich Carl Glaser have hereunto set my
hand and seal this twenty-third day of April in the year of our Lord one thousand,
eight hundred and eighty four.
