IMPROVEMENTS IN EMBROIDERING MACHINERY
Year: 1877

page_text: LETTERS PATENT to Joseph Lindley, of the City of Manchester, Manufacturer,
for the Invention of "IMPROVEMENTS IN EMBROIDERING MACHINERY."
Sealed the 26th February 1878, in pursuance of an Order of the Lord Chancellor,,
PROVISIONAL SPECIFICATION left by the said Joseph Lindley at the Office
of the Commissioners of Patents on the 14th August 1877.

EMBROIDERING MACHINERY."
"IMPROVEMENTS IN
The object of this Invention is the construction of an embroidering machine
capable of producing parallel rows of Bonnaz embroidering stitches simultaneously
upon any required description or thicknesses of textile, fels, or other fabric.
I take a series of Bonnaz needles, corresponding in number to the rows of stitches
I require, and mount them side by side in a frame, and impart a reciprocating;
motion to such needles; these needles all pass through a bar perforated at the desired,
distance apart, which forms a shield for the needles; or if the distance between the.
needles is sufficient, I then use the ordinary nipples employed in Bonnaz embroi-,
dering machines for each needle.
The twist or throwing of the threads round the needles to produce the Bonnaz
stitch is effected by a bar actuated by a pair of suitable cams; this bar being
provided with a number of guides or loops (corresponding in number to the needles);
which lead the threads from a series of bobbins mounted within a creel; the drawing;
off of these threads being effected by an oscillating shaft and faller bar, whilst the
necessary tension is obtained by a small weight suspended upon each of the
threads.
I am thus enabled to produce a number of Bonnaz embroidery stitches simul-
taneously for the purpose of ornamenting fabrics in parallel rows or lines of any.
desired colors, or for the sewing together of two or more thicknesses of materials.

"IMPROVEMENTS IN
The object of this Invention is the construction of an embroidering machine
capable of producing parallel rows of Bonnaz embroidery stitches simultaneously
upon any required description or thicknesses of textile, felt, or other fabric.
I take a series of Bonnaz needles, corresponding in number to the rows of stitches
I require, and mount them side by side in a frame, and impart a reciprocating
motion to such needles; these needles all pass through a bar, perforated at the desired
distance apart, which forms a shield for the needles; or if the distance between the
needles is sufficient, I then use the ordinary nipples (employed in Bonnaz embroi-
dering machines) for each needle.
The twist or throwing of the threads round the needles to produce the Bonnaz ]
stitch is effected by a bar actuated by a pair of suitable cams; this bar being
provided with a number of guides or loops (corresponding in number to the needles)
which lead the threads from a series of bobbins mounted within a creel; the drawing
off of these threads being effected by an oscillating shaft and faller bar, whilst the
necessary tension is obtained by a small weight suspended upon each of the s
threads.
:
I am thus enabled to produce a number of Bonnaz embroidery stitches simul-
taneously, for the purpose of ornamenting fabrics in parallel rows or lines of any
desired colors; or for the sewing together of two or more thicknesses of materials.
In order that this my said Invention may be more readily carried into effect, I s
have hereunto annexed a Drawing of the essential parts of my multiple Bonnaz
embroidering machine, drawn to a scale of about 1/2 inches to the foot.
Fig. 1 is a sectional view upon the line a, b, in Fig. 2.
Fig. 2 is a partial front elevation; and Fig. 3, a side elevation.
"
A, A, A, A, are a series of Bonnaz needles secured, by means of clamping bar Ba
to the reciprocating frame C. D is a perforated bar, perforated to correspond with
the needles A, and which may form the shield for the said needles, or of the distance
between the needles will admit. I prefer to use the ordinary Bonnaz nipples E, E, E,
secured in such bar, as shewn. F, F, F, are the guides or loops for throwing the
threads round the needles in forming the Bonnaz stitch. The threads are supplied
to these guides or loops from the creel G, by a self-acting drawing-off motion con--
sisting of a slotted bar or tube H, provided with a lever I, to which reciprocating
motion is imparted at each stitch; each of the threads passes through this slotted
bar and under the faller bar J 'which is connected to the bar or tube H, and partakes
of the same reciprocating motion at each downward movement of the faller bar J, 4
a given amount of thread is drawn off the creel G, and as the faller bar returns,
the thread is kept tight by a small weight K which is suspended from a runner or
eyelet upon the thread, and thus a constant tension is maintained in the threads,
irrespective of the size of the bobbins.
Although I have only shewn a small number of needles in use, it will be apparent
that any required number may be put in, limited only by the width of the machine,
and that the space between the needles may be varied according to the pattern being,
embroidered.
I will now proceed to describe how the necessary motion is communicated to
the various parts.
The reciprocating frame C is guided in the bars L (one at each side of the machine), .
and receives its motion from the cam M upon the main shaft N, driven in the
ordinary manner (a side view of this cam and the necessary friction bowls is
seen at Fig. 2a).
:

page_text: The perforated bar D carrying the Bonnaz nipples (by means of the guide rods O
which pass through the reciprocating fram C, is connected to the longitudinal bar P,
to which the necessary motion is imparted by the cam Q upon the main shaft N,
through the friction bowl and link R. I employ several of these cams and connections
in the length of the machine in order to give steadiness to the movement
according to the width of machine.
In order to give proper throwing movement to the guides or loops F, I mount a
cross shaft S' in bearings T, branching from the main frame, and which is driven
from the main shaft N through the bevil wheels V.
!
The cam W, as it revolves, imparts the necessary traversing motion to the loops
through the lever X and fork Y, whilst the oscillating movement is derived from
the cam Z upon the main shaft N through the link a and arm b; the two movements
combined producing the throwing movement necessary to produce the Bonnaz
stitch.
Having thus particularly described and ascertained the nature of this my said
Invention, I desire it-to be understood that I make no claim to the use of a
single Bonnaz needle, nor to the guiding loops for carrying or throwing the threads,
but what I do claim is,-
-
First. The use of a number of Bonnaz needles for producing parallel rows of
Bonnaz stitches simultaneously.
Second. The combination and arrangement of machinery consisting of a series
of Bonnaz needles, guides or loops for throwing the threads, and actuating
mechanism, substantially as and for the purposes described, and illustrated on the
accompanying Drawing.
In witness whereof, .I, the said Joseph Lindley, have hereunto set my hand
and seal, this 27th day of February, in the year of our Lord One thousand
eight hundred and seventy-eight.
JOSEPH LINDLEY. (LS.)
