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 inven-
tion to be as follows:-
The invention has for its object improvements upon an invention for which Letters
Patent were granted to W. Birks and H. S. Cropper, dated January 26, 1888,
No. 1206, and relates to a novel construction and method of operating the thick thread
guides, by which simplicity of construction is secured and a better view of the work
is obtained as it progresses.
For this purpose I dispense with the rotating thick thread guides or pinions, and
the gearing for giving motion to the same, shown and described in the specification of
the aforesaid Patent, and I substitute therefor the construction and arrangement of
parts substantially as hereinafter described.
To a bar extending lengthwise of the machine, I attach a number of guides, one for
each embroidery needle, preferably formed of wire, but which may be otherwise made;
each of these guides has an eye at the outer end, through which the thick thread or other
embroidery material employed, is passed, and I give motion to the aforesaid bar in
such manner as to cause the guides attached thereto to reciprocate around the coacting
needles first in one direction and then in the other, whereby each guide is caused to
carry its thread first to one side and then to the other side of the needle, thereby
causing the needle, as described in the aforesaid specification, to stitch such thick
thread or other material to the lace or other fabric to which it is to be applied, by
alternately stitching on each side thereof, and not by passing through the saine.
These thick thread guides are so bent or formed as to enable the guide eye thereof to
make somewhat more than a complete rotation around the needle; for this purpose,
the stem of the guide has a straight portion by which it is connected to the bar and a
doubly curved portion which connects such straight portion with the guide oye; this
will enable the guide to clear the needle throughout its entire motion, as when in the
extreme position in both directions, a curved portion of the guide stem will partly
surround the needle.
One method of giving motion to such bar of guides is to mount it in vertical guides,
and to employ two cams at each end and at intermediate distances, to act upon such
guide bar, one of such cams giving motion to the same in a vertical direction and the
other in a horizontal direction, the combined action giving the desired reciprocating
motion to the guides around the needles. These cams may be operated in any suitable
manner which will give the required reciprocating motion thereto; for instance, a
toothed wheel may be mounted on the axis of each pair of cams and a reciprocating
rack-bar may be employed to give simultaneous motion to the toothed wheels and
cams.
Other means may however be employed to give the required motions to the guide
bar.

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 inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement, reference being had to the
accompanying drawings and to the figures and letters marked thereon:-
The invention has for its object improvements upon an invention for which Letters
Patent were granted to W. Birks and H. S. Cropper dated January 26, 1888,
No. 1206 and relates to a novel construction and method of operating the thick thread
guides by which simplicity of construction is secured and a better view of the work is
obtained as it progresses.
For this purpose I dispense with the rotating thick thread guides or pinions and the
gearing for giving motion to the same shown and described in the Specification of the
aforesaid Patent and I substitute therefor the construction and arrangement of parts
substantially as hereinafter described.
To a bar extending lengthwise of the machine I attach a number of guides, one for
each enibroidery needle, preferably formed of wire but which may be otherwise made,
each of these guides has an eye at the outer end through which the thick thread or
other embroidery material employed is passed and I give motion to the aforesaid bar
in such manner as to cause the guides attached thereto to reciprocate around the
coacting needles first in one direction and then in the other whereby each guide is
caused to carry its thread first to one side and then to the other side of the needle
thereby causing the needle as described in the aforesaid specification to stitch such
thick thread or other material to the lace or other fabric to which it is to be applied
by alternately stitching on each side thereof and not by passing through the same.
These thick thread guides are so bent or formed as to enable the guide eye thereof
to make somewhat more than a complete rotation around the needle; for this purpose
the stem of the guide has a straight portion by which it is connected to the bar and a
doubly curved portion which connects such straight portion with the guide eye, this
will enable the guide to clear the needle throughout its entire motion as when in the
extreme position in both directions a curved portion of the guide stem will partly
surround the needle.
One method of giving motion to such bar of guides is to mount it in vertical guides
and to employ two cams at each end and at intermediate distances to act upon such
guide bar one of such cams giving motion to the same in a vertical direction and the
other in a horizontal direction the combined action giving the desired reciprocating
motion to the guides around the needles. These cams may be operated in any suitable
manner which will give the required reciprocating motion thereto; for instance a
toothed wheel may be mounted on the axis of each pair of cams and a reciprocating
rack bar may be employed to give simultaneous motion to the toothed wheels and
cams.
Other means may however be employed to give the required motions to the guide
bar.
In the accompanying drawings
Figure 1 is an end view and Figure 2 is a front view of parts showing my present
invention applied to a "Swiss embroidery machine."
Figure 3 is a cross section drawn to a larger scale of parts thereof.
Figures 4 and 5 are respectively a front elevation and a cross section showing my
improvements and the ordinary embroidery needle and shuttle drawn half full size.
Figure 4 is a plan of some of the parts shown at Figure 4, and
Figure 6 is a separate view of one of the guides drawn full size.
In all the figures like parts are indicated by similar letters of reference.
I would here remark that I have shown only so much of the machine as will clearly

page_text: illustrate the class of machine to which I refer and the method of applying my inven-
tion thereto.
a. a represent parts of the frame of the machine, b. b are needle bars or leads fixed
to bars 6 carried by guide bars 62 which are connected to levers 63 fixed on a shaft b¹.
In the machine represented in the Drawing there are two sets of embroidery
instruments of a precisely similar character and acting simultaneously on the fabric,
there are therefore two shafts 64 to which other levers 6 are fixed which are connected'
together by links or connecting rods 6°..
Motion is given to one or other of the shafts 64 in the ordinary manner, 67 is a
needle, c is the bar on which the shuttle race is formed, c¹ are shuttles, c² is the bar
for giving motion to the shuttles c¹ through the medium of the drivers c³; d. d are
bobbins for supplying ordinary embroidery thread to the needles, which thread is
conducted from the bobbins d. d around rollers d¹, over the bar d², under the
bar d³, and thence through holes in the leads or bars 6 to the needles.
The fabric to be embroidered is carried by and strained between rollers e. e supported
in a frame e which carries the fabric æ in a vertical position between the needles 6*
and the face of the shuttle race or bar e; and such frame e¹ is guided vertically by
vertical roller guides e² and is supported at the top of the machine on rollers e³ and
such frame e¹ is operated by means of a pantagraph (not shown) to move the work in
any required vertical or horizontal direction in a vertical plane according to the pattern
to be produced as is well understood.
The parts above described are common to this description of embroidery machine
and the moving parts are operated by cams and levers in any ordinary manner.
According to my invention 1 combine with each needle b' a guide ƒ formed
preferably of wire and having the guide eye f¹ connected by a doubly curved portion f
to the stem of the guide, and such guides fare formed with loops f³, by which aided
by screws f, they are fixed to bars g¹ fixed to the upper and lower parts of a frame g
which is guided to move in a vertical plane in any direction within certain limits, as
will be hereinafter described.
This frame g is formed with a cross bar g² and vertical bars g³, which respectively
rest upon and against cams hi which give combined vertical and horizontal motion to
the said frame g in a vertical plane in such manner as to cause the guide eyes f¹ to
travel around the needles b' first in one direction and then in the other, the motion of
such guide eyes being so controlled by the cams h. i. as to cause the doubly curved
portions to travel clear of the needles 67 in a path somewhat the shape of a spiral or
scroll so that when the guide eyes are in the extreme position in one or the other
direction the needles shall pass through the centres of one or other of the curves 1. 2 of
the part 2 as indicated at Figure 6.
The bars g¹ are fixed to the upper and lower returned ends of the vertical bars 9³ by
means of screws 9 passing through said returned ends and through interposed distance
pieces 9 and screwing into the bar g' thus leaving a space or mortise between the
bars g and g³ to receive a sword or arm g6 fixed to a bracket g' which is fixed to the
frame of the machine. Each angle formed by the bars gl and g³ is fitted as above
described and at intermediate places along the length of the bars g¹ other similar mortises
or spaces are formed to receive other like swords or arms 9. By these means the said
bars gl are firmly and correctly guided with capability of moving within certain limits
in any direction in a vertical plane as moved by the cams h. i.
The cams h, i, of which there are two or more pairs along the length of the machine,
are mounted on axes j fixed to brackets k and they have connected to each pair thereof
a toothed pinion l. These toothed pinions are acted upon by toothed racks m fixed
to a reciprocating bar m¹ which is mounted on guide rollers n. n and is connected at
one end by a link m² with a bell crank lever m³ which by a link m' is connected to a
lever m acted upon by a cam me fixed on the counter shaft m².
The thick or other embroidery thread or cord o that is to be stitched to the fabric
by the ordinary embroidery thread passing through the eyes of the needles b', is con-
tained on bobbins o' and passes from such bobbins over the rollers o², over the bar d³,
through the eyes of the tension wires o³, and thence through the guide holes f¹ in the

page_text: guides to the fabric x, upon which it is stitched by the ordinary needle embroidery
thread passing alternately on each side thereof.
At any time if required by the design the guides f may be thrown out of action, as
has already been proposed with respect to the rotary wheel guides, by the attendant
operating the pantagraph, who by the action of the foot upon a treadle (not shown)
connected to the rod m" throws the clutch m³ into or out of gear with the cam m³,
thus connecting said cam with its shaft m² or disconnecting it therefrom at pleasure ;
whilst the needles continue to do embroidery of the ordinary description.
The counter shaft m receives rotary motion from the shaft m10 by the toothed
gearing m³ and said shaft m¹0 is rotated in the ordinary manner.
By the aid of my invention I am enabled to embroider with almost any thickness
and character of cord, such as cannot be used with the rotating wheel guide heretofore
in use; my improved apparatus moreover does not obstruct the view of the work like
the rotary guide and pinion and rack heretofore in use, which cause a considerable
amount of friction and frequently cause the thick or extra braiding cord to catch,
thereby making bad work and entailing frequent stoppages; the reduced friction of
my improved apparatus will also admit of the embroidery machine being driven at a
quicker rate.
I would here remark that my invention is not confined in its application to the
shuttle embroidery machine shown in the drawings but it is also adaptable to all kinds
of multiple needle embroidery machines driven by hand or power and worked with
pantagraph or Jacquard as well as to a combination of embroidery machine with a
lace machine.
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 :
1. The combination with multiple needle embroidery machines operated by means
of a pantagraph or Jacquard as well as with combined lace making and embroidering
machines, of extra embroidery thread or cord guides formed each with a guide eye
connected by a doubly curved portion with its stem which is fixed to a bar operated
in such manner as to cause the extra embroidery thread or cord guide to travel first
in one direction and then in the other around the needle in such a path as to clear the
needle and carry its cord or thread first to one side and then to the other of the
needle, substantially as herein shown and described and for the purpose stated.
2. The combination with multiple needle embroidery machines as well as with com-
bined lace making and embroidering machines of extra thread or cord guides formed
each with a stem, a carrier eye and a doubly curved portion connecting the eye to the
stem, a bar to which the extra thread or cord guides are fixed, a frame to which the
bar is fixed, moving in a vertical plane in any direction, having a cross bar and vertical
bars, cams on which the cross bar rests, cams against which the vertical bars bear,
axes on which the cams are fixed having a pinion, and a reciprocating rack bar
substantially as herein shown and described and for the purpose, stated.
