PROVISIONAL SPECIFICATION.
Improvements in or connected with Embroidery Machines.
1, FREDERICK JAMES PERRY, of 5, Arboretum Street, in the Town and
County of the Town of Nottingham, Lace Manufacturer, do hereby declare the
nature of this invention to be as follows:
-
The invention relates to that class of multiple needle embroidery machine in
which a thick or other extra embroidery thread has been sewn on to lace or
other fabric by the ordinary needle or embroidery thread passing over the same
and forming a stitch alternately on either side thereof.
Heretofore in such class of machine the thick or other extra embroidery
thread has passed from the bobbin, around a roller, over a guide bar, and thence
through the eye of a comparatively heavy weight or lingoe, which has acted, in
combination with the pull of the work, to draw off such extra embroidery
thread from its bobbin and keep the same in tension. It has been found that such
method of drawing off the extra embroidery thread applies too great a strain thereto
and therefore interferes with the free working thereof, which results in slight dis-
tortions of the pattern, that is to say, such extra embroidery thread, in consequence
of the great drag put thereon it drawing it off the bobbin, does not lie in such
smooth or easy lines and curves on the fabric as can be obtained by the aid of the
present invention.
Now in lieu of, as heretofore, drawing off the extra embroidery thread from its
bobbin as above described, such extra embroidery thread is according to the present
invention passed as direct as possible to the guide eye from the roller around which
it passes on leaving the bobbin, and the comparatively heavy tension and draw off
weight is dispensed with, and in lieu thereof the aforesaid or other suitable roller is
converted into a draw off roller by any suitable arrangement of parts, a convenient
arrangement being to mount on the end of such draw off roller a ratchet wheel,
which is operated by a driver to which motion is given by a suitable cam and
suitable, preferably adjustable, connections. A lingoe or small weight is however
hung on the extra embroidery thread after the latter has passed the draw off
roller, but such weight or lingoe is only sufficiently heavy to keep the said
embroidery thread straight, without putting any great strain thereon.

COMPLETE SPECIFICATION.
Improvements in or connected with Embroidery Machines.
1, FREDERICK JAMES PERRY, of 5, Arboretum Street, in the Town and County
of the Town of Nottingham, Lace 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 :-
The invention relates to that class of multiple needle embroidery machine in
which a thick or other extra embroidery thread has been sewn on to lace or other
fabric by the ordinary needle or embroidery thread passing over the same and
forming a stitch alternately on either side thereof.

page_text: Heretofore in such class of machine the thick or other extra embroidery threa
has passed from the bobbin, around a roller, over a guide bar, and thence through
the eye of a comparatively heavy weight or lingoe, which has acted in combina-
tion with the pull of the work to draw off such extra embroidery thread from its
bobbin and keep the same in tension. It has been found that such method of
drawing off the extra embroidery thread applies too great a strain thereto and
therefore interferes with the free working thereof, which results in slight distortions
of the pattern, that is to say, such extra embroidery thread, in consequence of the
great drag put thereon in drawing it off the bobbin, does not lie in such smooth
or easy lines and curves on the fabric as can be obtained by the aid of the
present invention.
Now in lien of, as heretofore, drawing off the extra embroidery thread from its
bobbin as above described, such extra embroidery thread is according to the
present invention passed as direct as possible to the guide eye from the roller
around which it passes on leaving the bobbin, and the comparatively heavy
tension and draw off weight is dispensed with and in lieu thereof the aforesaid
or other suitable roller is converted into a draw off roller by any suitable
arrangement of parts, a convenient arrangement being to mount on the end of
such draw off roller, a ratchet wheel which is operated by a driver to which motion
is given by a suitable cam and suitable, preferably adjustable, connections. A
lingoe or small weight is however hung on the extra embroidery thread after the
latter has passed the draw off roller, but such weight or lingoc is only sufficiently
heavy to keep the said embroidery thread straight without putting any great strain
thereon.
And in order that my said invention may be more clearly understood and readily
carried into effect, I will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an end view and Figure 2 is a front view of parts of a multiple
needle embroidery frame showing my present invention applied thereto. Figure 3
is an end view and Figure 4 is a front view of some of the parts shown at Figures 1
and 2 drawn to a larger scale. Figure 5 is a detail view.
In all the figures like parts are indicated by similar letters of reference.
a, d, represent parts of the frame of the machine, b is one of the needle bars or
leads fixed to bars carried by guide bars 2 which are connected to levers (not
shown) fixed on shafts 3. In the machine represented in the drawings, there are
two sets of embroidery instruments of a precisely similar character and acting
simultaneously on the fabric. I have represented only the upper set of such
instruments in Figures 1 and 2 and only the lower set in Figures 3 and 4.
In Figures 1 and 21 have shown my improved drawing off apparatus for the
thick or extra thread as arranged for the two sets of embroidery apparatus.
The shafts 63 giving motion to the needle bars are operated in the ordinary
manner, is a needle, c is the bar on which the shuttle race is formed, c' is a
shuttle, is the bar for giving motion to the shuttles through the medium of the
drivers c, d, d, are the bobbins for supplying ordinary embroidery thread to the
needles, which thread is conducted from the bobbins d around rollers d', over
the bar d², under the bar 43, and thence through holes in. the leads b to the needles.
The fabric to be embroidered is carried by and strained between rollers ee
supported in a frame e which carries the fabrice in a vertical position between the
needles and the face c of the shuttle race or bar c; such frame e' is guided
vertically and is supported at the top of the machine, and it is operated by means
of a pantagraph to move the material to be embroidered in any required
direction in a vertical plane, according to the pattern to bo produced as is well
understood.

page_text: The parts above described are common to this description of embroidery machine,
and the moving parts are operated by cams, levers, and other apparatus in any
ordinary manner.
Embroidery machinery arranged as above described has also had combined
therewith reciprocating guides for the purpose of enabling a thick or extra
embroidery thread to be laid alternately on each side of each needle and to be
stitched to the material by the ordinary embroidery thread as described in the
Specification of Letters Patent No. 1206 of the year 1888 granted to H. S. Cropper
and W. Birks, and in the Specification of Letters Patent No. 16390 of the
year 1889 granted to myself, and my present invention applies to such improved
class of embroidery machine.
In the drawings represents one of the above mentioned thick or extra thread
guides, as described in my aforesaid Specification, and g represents part of the frame
carrying such guides.
The thick or extra embroidery threads or cords that are to be stitched to the
material by the ordinary embroidery threads and needles, are contained on
bobbins ', and according to my present invention, pass from such bobbins around
rollers h², thence through the eyes of light lingoes or weights ³, thence over guide
wires under the needle bars where possible but over the same at other parts,
and thence through the reciprocating guides to the material on to which it is to
be stitched. I also mount on the end of each draw off roller h², a ratchet wheel,
which ratchet wheels are operated by pawls or drivers mounted on a rod j
working in guides. This rod is pulled in an upward direction by a spring,
whilst it is depressed in the following manner to effect a
partial rotation of the
ratchet wheels and draw off rollers and thereby draw off the required length of
thread or cord from the bobbins . On the cam shaft is a small cam 1, which
acts upon a lever to raise it, whilst a spring 12 acts to pull such lever downwards,
so as to keep it constantly against the cam ; such lever is connected to the
lower end of a bar 3, which latter is connected at its upper end to a lever * to
ensure said bar moving in a vertical direction. On the bar 13 is a stud or pin,
which acts on an arm or wire projecting from the driving rod j, so that when
the bar is depressed, it shall also depress the driving rod and thereby cause
the draw off rollers to draw off the required length of thread or cord from the
bobbins. The lingoes or weights 3 employed are as light as possible, their
only object being to keep the threads or cords straight without putting any
great strain thereon. It will be evident that other arrangements of apparatus
may be employed for giving motion to the draw off rollers. A friction band m
passes over the boss of each ratchet wheel to prevent any slip of the rollers h³,
and such bands m are fixed at one end to a rod or rail m' and at the other to
a spring m² which is held with capability of adjustment by a fly nut m³.
The driving rod is capable of being put out of action when desired in the
following manner. At the lower end of such driving rod j is a slot, through
which passes a pin n, which is adjustably fixed on a link n', and this link is
mounted on one arm of a crank lever n² the other arm of which is connected
to the sliding rod n³ by which the crank lever n² can when desired be caused
to pull down the driving rod j and thus cause the arm to be removed out of
range of the pin or stud 1.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In multiple needle embroidery machines of the character described in the
Specifications of Letters Patent before referred to, the employment of a draw off
roller operated by mechanical means for drawing the thick or extra embroidery
threads off their bobbins, substantially as herein shown and described.
2. In multiple needle embroidery machines of the character above referred to

page_text: the employment, in combination with the bobbins carrying the thick or extra
embroidery threads, of drawing off rollers, ratchet wheels fixed on the ends of such
rollers, and pawls or drivers acting on such ratchet wheels and operated substantially
as herein shown and described.
