I, RICHARD VOIGTLÄNDER of Gohlis Leipzig in the Kingdom of Saxony Empire
of Germany, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to frames for carrying the cloth or fabric to be embroidered
either in embroidering machines or in sewing machines with which such embroidering
mechanism is employed as an attachment.
The frame is moved in connection with a pantagraph by or through the following
improved connections whereby the orienting of the frame is retained. To a suitable
plate adapted to be rigidly secured, are pivoted two or more parallel and equal rods or
bars the opposite extremities of which are pivoted to a plate or bar-To this plate or
bar are likewise pivoted two or more parallel and equal rods pivoted at their opposite
ends to a plate or bar to which the cloth frame may be firmly fixed-One of the first
mentioned parallel rods is extended beyond its movable pivotal point, and its outer
end is pivoted to one end of a long arm having at its further end an index point or
stylus for passing over the pattern-The last mentioned frame supporting plate or bar
is connected to said arm by a rod pivoted at its extremities to each respectively, of a
length equal to that of the extension of the rod pivoted to said arm, and parallel to
said extended rod.
The movement of the stylus on the long arm is therefore transfered in a reduced
measure to the cloth frame and the manner of connecting the frame to the stationary
base plate before mentioned ensures the orienting of the frame being preserved.
The frame may be secured to the plate or bar for supporting the same by means
of a screw threaded pin passing through a slot in an ear on said frame and a thumb
nut or the like screwed down thereon-The stationary base plate of the mechanism if

page_text: applied to a sewing machine attachment is provided with.a. suitable clamp for fixing
it to the table or plate of the sewing machines.
The connecting rods of the mechanism may be made adjustable for varying the
proportion of the embroidering and the pattern.

Embroidering Machines, and the like.
RICHARD VOIGTLÄNDER of Gohlis Leipzig in the Kingdom of Saxony, Empire
of Germany, Manufacturer 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 :-
This invention relates to embroidering attachments for sewing machines in which
a frame carrying the fabric to be embroidered is caused to move through intervention
of a pantagraph in correspondence with the stylus or guide point thereof connections
being contrived between the said frame and the table of the sewing machine or
other fixed part thereof whereby the orienting of the frame is preserved during its
movement.
The improvement relates to the manner and means of connecting the frame afore-
said holding the fabric to be embroidered (hereinafter called the cloth frame) to the
pantagraph and to the table or other fixed part of the sewing machine (hereinafter
referred to as the table).
A further improvement lies in the rendering of the cloth frame detachable from the
remainder of the parts of the embroidering attachment and in the manner of connecting
it thereto.
A further improvement lies in rendering the parallel guiding arms together with
the pantagraph arms adjustable in length whereby the proportion between the
movement of the cloth frame and that of the pantagraph point may be varied for
embroidering on a comparatively large or small scale from one pattern.
To these ends the invention consists in the combinations of parts substantially as
hereinafter described and specifically pointed out in the claims.
Referring to the accompanying drawings
Fig. 1 is an elevation of the table of the machine with the improved attachment
fixed thereon.

page_text: Fig. 2 is a plan view of said attachment.
Fig. 3 illustrates in plan and elevation a portion of the cloth frame and part to
which it is attached showing the improved mode of attachment.
Fig. 4 is a similar view in plan showing a slightly modified manner of connection.
Figs. 5, 6, 7, 8 and 9 illustrate in plan modifications of the improved attachment,
Fig. 7 showing more particularly the manner of rendering the length of the parallel
guiding arms and pantagraph arms adjustable this improvement being however equally
applicable to all the forms shown.
Fig. 10 shows on a larger scale in plan a modified method of connecting the cloth
frame to the part immediately supporting the same.
Figs. 11 and 12 illustrate the same in cross section, Fig. 11 showing the frame
fixed, Fig. 12 the parts in relative position for fixing.
The attachment consists essentially of a stationary plate (hereinafter called table
plate), an intermediate plate connected to said table plate by a set of two or more
parallel rods of equal length, a third plate for supporting the cloth frame (hereinafter
called the frame plate) connected to said intermediate plate by a second set of two
or more parallel rods of equal length, one of said connecting rods, whether of the
first or second set being extended or prolonged to form that outer arm of the pantagraph
which does not carry the stylus or point, one of the other sets of connecting rods
forming one of the innor arms of the pantagraph.
A stylus arm pivoted to the outer end of the aforesaid extended rod and the second
inner arm of the pantagraph the same being equal in length to the extended portion
of the beforementioned extended rod and parallel thereto connecting the stylus arm to
the table plate or frame plate. In the drawings m represents the table plate the same
being of convenient form and fixed to the table o or other firm part of the sewing
machine by means of a clamp such as indicated in Fig. 1 or by other means
according to the nature of the sewing machine. d is the intermediate plate, the same
being connected to the plate m by two or more parallel and equal rods c. In Fig. 2
three rods c are employed whereas in Figs. 5, 6, 7 and 8 only two are shown. The
plate may be of any convenient form, for instance triangular as in Fig. 2, a simple
bar as in Fig. 8 or an L shaped bar as indicated in Figs. 5 to 7. in which latter case
the rods c may be connected at the extremities of the bar, or one at one extremity
and one at the angle of the bar.
s is the frame plate; the latter being either a simple bar or an L or other shaped
bar according to the manner of arrangement of the rods which connect it to the
intermediate plate d; the said rods are equal in length and parallel, preferably two in
number.
One of the rods for c is extended in a direction from the intermediate plate d and
the said rod so extended forms the arina of the pantagraph one of the rods c or f
respectively of the set, other than that of which the aforesaid rod was extended forms
one of the inner arms a' of the pantagraph and the latter is completed by the other
inner arm a and the stylus arm a³ as above described. The construction shown in
Fig. 9 differs only in that the intermediate plate d is removed and replaced by an
equivalent construction namely the prolongation of the two parallel rods c to an equal
length the connection of the same at their extremities by the plate d' the rods c c
being connected to the rods at the points where the plate d would have been
connected.
The essential features of the connection of the cloth frame and frame plate are
that the frame should have an ear adapted to overlap said plate said car being
perforated and said plate tapped thereunder to receive and engage a screw passed
through the said ear, that the ear and plate should be prevented from relative
rotary movement about said set screw. Referring to Figs. 3, 4, 10, 11 and 12 the
cloth frame is provided with the ear n having slot e and in the plates is tapped a
hole adapted to receive the screw a. To prevent rotary displacement the plates may
carry the piur adapted to engage into the hole r¹ in ear n or the latter may have the
flange n¹ abutting upon the edge of the plate s.
In the latter case the slot is preferably chamfered and is of comparatively large

page_text: diameter, the screw a then carries the conical part a' bearing into said chamfer and
adapted when screwed down to centre said chamfered slot and thereby bring the
flange n' into firm contact with the edge of the plate s. By this means also on
loosening said screw the frame p may be lifted as upon a hinge for more commodious
adjustment of the fabric therein. When a pin r is used as aforesaid the slot vis
preferably open laterally of the earn so that on loosening the screw z without removal
of same the ear may be lifted off the pin r and thereupon slid from under the head of
the screw and so removed.
For adapting said attachment for adjustment in the manner similar to that in which
pantagraphs are heretofore rendered adjustable the rods c and fare provided along
their length with equidistant boles whereby the length of connection between the frame
plate s intermediate plate d and table plate m may be varied in accordance with
the adjustment of the pantagraph, the arms of the latter being also provided with
such holes.
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 :
