Improvements in the Method of Embroidering Small Pieces of
Fabric.
I, GEORG BAUM, of Rorschach, Canton St. Gallen, in the Republic of
Switzerland, Engineer, do hereby declare the nature of this invention to be as
follows:-
:-
Heretofore in embroidering small square pieces of fabric, such as pocket-
handkerchiefs, a separate frame for each of the same has been used, which frames
were fitted into the outer frame and to facilitate the embroidering of the four
edges of each piece of fabric after the first edge, the said small frames had to be
turned individually about 90 degrees in order to bring the four edges successively
to the height required for the needles when embroidering.
This invention has for its object to reduce the number of such small frames and
separate turns to be imparted thereto in such a manner that for instance, when
embroidering sixteen pieces of fabric, three turns only are necessary to turn the
whole of the sixteen pieces, in lieu of as heretofore three times sixteen === 48 turns.
To this end in lieu of employing frames holding each a small piece of fabric, a
frame (see Fig. 1, of annexed drawing) is employed, which extends over several
rows of needles, preferably the whole height of the outer frame and which holds
not one but a number of such pieces of fabric t forming an undivided square piece,
for the purpose of embroidering simultaneously a square number (in the present
instance sixteen). The number of rows of needles n', n², n³, n', Fig. 2, corresponding
with the number of rows of pieces of fabric arranged above each other on the
inner frame r, i.e. sixteen pieces in four rows, on the said rows of needles proceeding
towards the outer frame they engage and embroider simultaneously the four rows
of edges of the whole of the pieces t upon the frame raud the latter after having
had imparted a turn of 90 degrees relative to the outer frame, bring first the
edges II, on a second turn the edges III and on a third and final turn the edges IV
of the whole of the pieces of fabrics to the height of the rows of needles to be
embroidered.
By the joint frame described a number of pieces of fabric (in the present
instance sixteen) must thus take part in the turn of one frame, i.e. the manipulation
hitherto necessary for the adjustment of each individual piece of fabric, suffices
for the simultaneous adjustment of the said number which is a considerable saving
of time.
In adapting embroidery machines in practice for this invention, two, three, four
or more rows of embroidery needles may be employed above each other for the
same fabric, in which case each inner frame must hold four, nine, or sixteen pieces,
and so forth, i.e. a number of pieces which will form a square for the rows of
needles employed.

shown in Fig. 1, i.e. with four rows, altogether sixteen pieces. The usual sizes of
machines admit of inserting into the outer frame y three such frames side by side
and the simultaneous production of three times sixteen 48 pieces. As each
inner frame after having embroidered one edge of each piece must be turned three
times, only nine turns are necessary after having been placed in its normal position
in a machine when employing three inner frames. Three inner frames being
employed side by side in the outer frame and three times three nine turns always
necessary, it being immaterial whether the inner frame holds four, nine, or sixteen

Improvements in the Method of Embroidering Small Pieces of
Fabric.
I, GEORG BAUM, of Rorschach, Canton St. Gallen, in the Republic of
Switzerland, Engineer, 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 in embroidering small square pieces of fabric, such as pocket
handkerchiefs, a separate frame for each of the same has been used, which frames
were fitted into the outer frame and to facilitate the embroidering of the four
edges of each piece of fabric after the first edge, the said small frames had to be
turned individually about 90 degrees in order to bring the four edges successively
to the height required for the needles when embroidering.
This invention has for its object to reduce the number of such small frames and
separate turns to be imparted thereto in such a manner that for instance, when
embroidering sixteen pieces of fabric, three turns only are necessary to turn the
whole of the sixteen pieces in lieu of as heretofore three times sixteen = 48 turns.
To this end in lieu of employing frames holding each a small piece of fabric, a
frame (see Fig. 1 of the drawings filed with the Provisional Specification) is
employed, which extends over several rows of needles, preferably the whole height
of the outer frame and which holds not one but a number of such pieces of fabric t
forming an undivided square piece, for the purpose of embroidering simultaneously
a square number (in the present instance sixteen). The number of rows of
needles n', n², n³, n, Fig. 2, corresponding with the number of rows of pieces of
fabric arranged above each other on the inner frame r, i.e. sixteen pieces in four
rows, on the said rows of needles proceeding towards the outer frame they engage
and embroider simultaneously the four rows of edges of the whole of the pieces t
upon the frame r and the latter after having had imparted a turn of 90 degrees
relative to the outer frame, bring first the edges 11, ou a second turn the edges III
and on a third and final turn the edges IV of the whole of the pieces of fabrics to
the height of the rows of needles to be embroidered.
By the joint frame described a number of pieces of fabric (in the present instance
sixteen) must thus take part in the turn of one frame, i.e. the manipulation hitherto
necessary for the adjustment of each individual piece of fabric suffices for the
simultaneous adjustment of the said number which is a considerable saving of
time.
In adapting embroidery machines in practice for this invention, two, three, four,
or more rows of embroidery needles may be employed above each other for the
same fabric, in which case each inner frame must hold four, nine, or sixteen pieces,
and so forth, i.e. a number of pieces which will form a square number of the needle
rows employed.

page_text: Fig. 2 of annexed drawing, is a vertical section of a machine with four rows of
needles n', n, n, n', adapted for embroidering pieces of fabric upon frames, as shown
in Fig. 1, i.e. with four rows, altogether sixteen pieces. The usual sizes of machines
admit of inserting into the outer frame y three such frames side by side and the
simultaneous production of three times sixteen = 48 pieces. As each inner frame
after having embroidered one edge of each piece must be turned three times, only
nine turns are necessary after having been placed in its normal position in a machine
when employing three inner frames. Three inner frames being employed side by
side in the outer frame and three times three nine turns always necessary, it
being immaterial whether the inner frame holds four, nine, or sixteen pieces, or so
forth, the saving of time owing to the reduction in the turns will thus be greater
in proportion to the increase of the pieces upon one of the inner frames. In order
to render the attention of the machine not too difficult, each inner frame is intended
practically for sixteen pieces only.

The inner frames on their sides are formed with teeth similar as the separate
frames heretofore in use and are inserted into the outer frame g by being slid into
a groove formed at the bottom by sheet metal strips c, so as to be guided and abut
sideways against stops a and be secured at the top by means of clamps k adapted
to turn on the wing screws of the outer frame.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim, is--
The method of and arrangement for reducing in "Heilman's" embroidering
machines the time required for turning individually a number of pieces of fabric,
consisting in fixing into a rectangular frame a larger piece of fabric intended for a
number of small pieces, turning the said fabric in its plane at a right angle after
having embroidered the first rows of the designs and then embroidering the others
across, i.e. rectangularly, the first rows at an angle of 90 degrees, all substantially
as set forth.
