AN IMPROVED EMBROIDERING MACHINE
Year: 1885

page_text: I, HERBERT JOHN HADDAN, of 67, Strand, in the City of Westminster, Civil
Engineer, do hereby declare the nature of said invention for AN IMPROVED
EMBROIDERING MACHINE, a communication to me from abroad by Friedrich Albin
Gräf, of Plauen, in the kingdom of Saxony, Manufacturer, to be as follows:-
This invention has for its object to construct a machine which can work either
with the ordinary needle-clips like Heilmann's embroidering machine, or as a
shuttle machine and can be easily converted from one kind into the other.
For this purpose the shuttle mechanism belonging to each row of needles is
mounted on a beam placed parallel to the main beam of the needle carriage, and
secured to two or more short arms adapted to turn on an axis parallel with the row
of needles; on the opposite side of this axis is situated another beam which carries
the needle clips belonging to a row of needles and is secured to extensions of the
same arms which carry the beam supporting the shuttle mechanism, so that the two
rows of needles and their mechanism, mounted on the same shaft are parallel, but
almost diametrically opposite to each other, and that either the one or the other
may be turned into the working position in front of the hanging frame, while the
other row is turned out of the way.
The shaft which supports the two beams, is held at each end by a bracket, which
is in its turn fixed to a plate, attached to the inner side of the main beam of the
needle carriage.
On the same shaft is fixed a hand wheel, provided on its circumference with
notches, which serve to fix the hand-wheel and therefore the shaft and the two
beams in the desired position by means of a spring or pawl adapted to fall into any
of the said notches, after the hand-wheel has been turned a certain distance.
The mechanism for setting in motion the shuttles or the needle-clips may be
similar to that of ordinary embroidering machines.
The needle carriage is suspended from a pair of vertical rods, each of which
carries at its lower end a hook provided with a knife edge bearing, and connected

page_text: with the rod by an excentric pin, by the turning of which the needle-carriage may
be lifted off its rails.
For better guiding the carriage, each side frame of the carriage is provided with
a slide-block adapted to slide in a slotted lever pivoted to the contiguous side frame
or stand of the machine, when the said lever or arm is placed horizontal.
For using the needle clips, the suspending hooks and the slotted arms are set out
of action, the latter being allowed to drop into a vertical position, while the
knife edges which support the carriage between its wheels are lifted out of their
bearings.

page_text: I, HERBERT JOHN HADDAN, of 67 Strand, in the City of Westminster, Civil
Engineer, do hereby declare the nature of this invention, a communication to me
from abroad by Friedrich Albin Gräf, of Plauen, in the kingdom of Saxony,
Manufacturer, and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
The embroidering machines hitherto in use have the inconvenience, that plain
and hollow fabric cannot both be cheaply produced on the same machine; the latter
requiring a Heilmann machine, while the former requires a shuttle machine.
To produce a machine, which may work all kinds of fabric at pleasure and with
advantage, the same must be so arranged that the clipping mechanism as well
as the shuttle mechanism can be employed in a suitable manner.
It is to be
considered as the chief condition, that the two different mechanisms are so
connected with the machine as to allow either of them to work with certainty
without requiring any complicated changes.
The said condition is fulfilled by the construction shown by Figs. 1-5 of the
accompanying drawings.
The shuttle mechanism, as well as the needle clips are arranged on double
carriers C adapted to turn with the axle, viz: each mechanism is rigidly connected
with the carriers, adapted to hold the needle clips and shuttles in a secure position
and to allow the required adjustment.
The beams A and B are rigidly connected with the axle D by the pieces C, and
the axle D is supported in the adjusting iron E, which is fixed to the tubular main
beams G by means of the brackets F.
The axle D carries a hand wheel H, serving to change the mechanism carriers
and provided with the notches or recesses h for the purpose of properly fixing the
position of the mechanisms. Into the recesses h fits a stop-spring J for securing the
whole rigidly in its position.
The various positions of the mechanism carrier for the use of the shuttles and
of the needle clips are clearly represented by Figs. 1, 2 and 3, sheet I of the
accompanying drawings, in which Fig. 2 shows the working position of the shuttle-
mechanism, while Fig. 3 represents the working position of the needle clips
Fig. 1 shows the needle carriage drawn backward. The mechanisms for the
movement of the shuttles, and of the needle clips are as usual. As the needle
carriage, during its function, alters but slightly its position, and this movement
must be produced as easily as possible, the carriage is suspended from the rods K,
which for this purpose carry the hooks L provided with knife edge bearings.
The hooks are excentrically pivoted in K, and each of the pivots a is furnished
with a square projection, by means of which the rotation is effected and the
carriage removed from the rail M.
For the easier guiding of the carriage, the carriage frames N are provided with
slide blocks O, adapted to slide in the slotted link P placed into a horizontal position
when working with the shuttles, see Fig. 4.
When the needle clips are used, the hook L and the link P are out of action, the
|latter being turned downward after loosening the screws Q, see Fig. 1.

page_text: The described machine is not only very simple in its arrangement, but also
convenient for attendance, especially as the working space is never influenced by
mechanisms suspended in front of the same, but is freely visible to the operator.
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
An embroidering machine having the following peculiar features for the purpose
of operating at will either with shuttle- or with needle-clip mechanism.
1. Shuttle- and needle clip mechanism mounted on beams A and B which are
rigidly connected with the axle D and adapted to be turned with the same by
means of a hand wheel H (which may be secured in its position by a spring and
stop notches) so as to bring either the shuttle or the needle clip mechanism into its
working position.
2. The employment of hooks L adapted to be lifted by excentric pivots, and of
guide links P, for lifting the needle carriage R off the rails M and for guiding the
same, when required.
