New or Improved Process and Apparatus for Producing Long
Pieces of Embroidery.
I JOSEPH KAUFFMANN, of 16, Albertplatz, Plauen, Vogtland, in the German
Empire, Merchant, do hereby declare the nature of this invention to be as
follows:-
According to this invention long pieces of embroidery are produced as follows:-
The material is first embroidered lengthwise of the machine, the part so
embroidered is then drawn sideways through the machine, and then after being
accurately adjusted another part of the material is embroidered lengthwise of the
machine, and so on until the desired length of embroidery has been produced, such
length being only limited by the length of the material.
This production of embroidery of any desired length is rendered possible because
the material to be 'embroidered is only used in narrow widths up to about
90 centimetres.
This narrow material can be easily moved through the machine in either direction
and be rolled up or folded at one side in an embroidered and at the other in an
unembroidered condition without hindrance to the working of the machine. The
material is fastened in the ordinary manner to the long tension bars.
In order to protect the material to be embroidered from injury by side tension
hooks, a tension frame or bar without hooks can be used, as shown in the
accompanying drawing which represents by way of example, one method of carrying
out the invention.
Two or more bars A A¹are so connected together that one or more of them can move
sideways. The material E is placed on these bars. A similar apparatus consisting of
two or more bars B B¹, each of which is likewise movable sideways, is then placed
on A A¹, in such a manner that, as shown in the drawing, the first bar A¹, for
example, of the upper apparatus, is placed between the two first bars B B¹ of the
lower apparatus, the second upper bar between the second and third lower bars, and
so on according to the number of bars employed.
By means of clamps C the two interlocking frames or apparatuses are pressed
together, and thereby held firmly to the material to be embroidered.
The above described apparatus takes the place of the side tension bars at present
in use in embroidering machines. The stretching of the material is effected in the
usual manner by means of the thumb-screws D.
Dated this 21st day of August 1897.

Pieces of Embroidery.
I, JOSEPH KAUFFMANN, of 16, Albertplatz, Plauen, Vogtland, in the German Empire,
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:-
Heretofore it has only been possible to produce, in what is known as the Heilmann
embroidering machine, lengths of embroidery not more than 4 metres long. Such
pieces of embroidery have been produced by stretching a piece of material of about
that length in the frame of the machine, embroiding it, and then rolling it up
vertically on a horizontal roller, but according to this present invention long pieces
of embroidery are produced as follows:-The material is first embroidered lengthwise
of the machine, the part so embroidered is then drawn sideways through the machine,
and then after being accurately adjusted another part of the material is embroidered
lengthwise of the machine, and so on until the desired length of embroidery has been
produced, such length being only limited by the length of the material.
This production of embroidery of any desired length is rendered possible
because the material to be embroidered is only used in narrow widths up to about
90 centimetres.
This narrow material can be easily moved through the machine in either direction
and be rolled up or folded, at one side in an embroidered, and at, the other side in an
unembroidered, condition, without hindrance to the working of the machine. The
material is fastened in the ordinary manner to the long tension bars.
In order to protect the material to be embroidered from injury by side tension
hooks, a tension frame or bar without hooks can be used, as shown in the drawing
accompanying the provisional specification filed with my application for a patent
which represents by way of example one method of carrying out the invention.
Two or more bars A A¹ are so connected together that one or more of them can
move sideways. The material E is placed on these bars. A similar apparatus
consisting of two or more bars B B¹, each of which is likewise moveable sideways, is
then placed on A A¹ in such a manner that, as shown in the drawing, the first bar A¹,
for example, of the upper apparatus, is placed between the two first bars BB' of the lower
apparatus, the second upper bar A between the second and third lower bars and so on
according to the number of bars employed.
By means of clamps C the two interlocking frames or apparatuses are pressed
together, and the material to be embroidered is thereby held firmly.
The above described apparatus takes the place of the side tension bar at present in
use in embroidering machines. The stretching of the material is effected in the
usual manner by means of the thumb screws D.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what I
claim is
First. The new or improved process for producing embroidery of any desired
length greater than that for which the embroiding machine is adapted, which
consists in moving the material horizontally or sidewise, instead of vertically as
heretofore, after completion of the embroidery on a given length of such material,
substantially as described.
Second. In an embroidering machine adapted to produce embroidery by the process
forming the subject matter of the first claiming clause hereof, a clamping device for
holding the material laterally while being embroidered, which consists of two frames

page_text: formed of parallel bars, such as A A¹ and B B¹, so arranged and adapted that one or
more of the bars of the one frame come between adjacent bars of the other frame,
clamping devices C for pressing the bars together, and screws D for stretching the
fabric E by moving the entire clamping device transversely, substantially as described
with reference to the aforesaid drawing.
