Attachments for Sewing Machines and for other Purposes
I, HENRY HARRIS LAKE of the firm of Haseltine Lake & Co Patent Agents,
Southampton Buildings, in the County of Middlesex, 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
1
This invention relates to an improvement in that class of embroidery attachments
for sewing-machines adapted to carry a cord, braid, or like material above the fabric
on the work-plate, and so that the said cord, braid, or like material will move with
the fabric under the feed of the sewing machine, but the cord also receives a move-
ment alternately to the right and left from the line of stitches, so that the stitches
will be made first upon one side, and then upon the opposite side of the said cord or
thread, the needle thread passing over the cord will serve to secure the cord to the
fabric, the pattern being produced by moving the fabric or work accordingly
invention also relates to the device for carrying the cord, thread, or braid, parts of the
said invention being applicable to other purposes
In the accompanying drawings
The
Figure 1 is a front view of the attachment showing the operating arm at one extreme
of its vibration
Figure 2 is a similar view to Figure 1 showing the operating arm at the other
extreme vibration, the gears being indicated in broken lines
Figure 3 is a side view, drawn to a reduced scale
Figures 4 and 5 are diagrams illustrating the eccentric or cam connection between
the active wheel and the lever

page_text: Figures 6, 7 and 8 show modifications in the eccentric connection between the active
wheel and the lever
A represents the frame, which terminites at its lower end in pres-er-foot A',
beneath which the work pisses, the frame is adapted to be attached to the presser-bar
of the sewing machine by a socket A2, or otherwise, and so as to retain its position in
the usual manner for similar attachments
On the frame A, a gear wheel B is arranged, upon an axis C, at right angles to the
plane of the frame
D represents a second gear wheel, like the gear wheel B, and of the same diameter
and teeth, it is arranged upon an axle E in the frame parallel with the axis C, and
so that the two wheels may work together, as represented in Figure 1, that the rotation
imparted to one may be communicated to the other
The wheel B is provided with a radially projecting arm F and with a second like
radially projecting arni G, the two arms being diametrically opposite each other
The wheel D is provided with arms H and I, diametrically opposite each other,
similar to the arms FG of the wheel B Preferably the arms project beyond the
working face of the wheels, but must always be so that the reciprocating device can
work between them so that as it moves in one direction, it will strike one arm, and
impart rotation to that wheel, and then moving in the opposite direction, the arm of
the other wheel will be presented for action, and so as to impart like rotation to the
said other wheel, and whereby the rotation of the wheels under both steps is in the
same direction
J represents lever, hung upon the frame, on a pivot K, and so as to swing in a
plane parallel with the axis of the two wheels B D, the lever is forked at its free end,
so as to engage with the needle arm that the reciprocating movement of the
lever arm may impart a vibratory movement to the said lever J, the needle bar is
not shown
The lover J extends to a point in front of the plane of the wheels, and so as to
work in the path of the respective arms F, G, H, I, as they rotate
As the lever J stands in the up position, the arm F of the wheel B is supposed to
have been turned up with it, as represented in Figure 1 Starting now from this
position, the lever J descends, and in its descent meets the arm H in its path, and
turns that arm downward to the position 2 indicated in broken lines Figure 1, which
imparts a corresponding rotation to its wheel D, and a corresponding reverse rotation
to the wheel B, carries the arm F, to the position 3 indicated in broken lines Figure 1
which brings the arm G to the position 4, at the same time the arm I of the
wheel D has been carried to the position 5, also seen in broken lincs, this will leve
the arm G at the position 4 above the lever J, and so that is the lever J next ascends,
it will strike the arm G at the position 4, and will cause that arm to 11se to the
position indicated by the arm F, Figure 1, which will impart a corresponding rotation
to the wheel B, and thence to the wheel D, and bring the arm I to the position
represented as occupied by the arm H in Figure 1, leaving that arm I then in the
path of the lever Jon its next descent, thus as the reciprocating movement is produced
downward, it acts through the one wheel D, and on the return movement it acts upon
the wheel B, alternately acting upon the respective wheels, but imparting an inter-
mittent rotation to both wheels, one step as the reciprocating device moves in one
direction, and the second step as the said device moves in the opposite direction, thus
from the reciprocating movement an intermittent rotation is imparted to the said two
wheels, first through one wheel as the reciprocating device moves in one direction,
and then through the other wheel as the reciprocating device moves in the opposite
direction
L represents an arm, which is hung to the frame A, and so as to swing in a plane
parallel with the plane of the wheels B D, as here represented the arm is hung upon
the axis of the wheel B, and the arm is constructed with an opening M through which
the axis E of the wheel D extends, so that the wheel stands upon the outer face of the
arm L, as represented in Figures 1 and 2
Into the opening Ma stud N on the wheel works, as a cam, the shape of the

page_text: opening M is such that the stud N working therein, imparts a swinging or vibratory
movement to the arm L, as from the position Figure 1, to that in Figure 2 and
return
The operation of the stud N on the cam shaped opening M in the lever L, is represented
in Figures 4 and 5, N represents the position of the stud on the wheel, and E the
axis of the wheel The position of the lever being at the left, as seen in Figure 1, as
the arm N moves, under rotation from the position 6 in Figure 1 to the position 7,
Figure 5, the shape of the opening in the arm is such that the stud forces the arm to
the opposite position, represented in Figure 2 From the position 7 through one-
fourth rotation to the position 8, the shape of the opening is concentric with the
axis E, as seen in Figure 5 From the position 8 through the third quarter to the
point 9, the shape is eccentric to the axis, consequently the stud acting against that
portion of the opening, returns the arm to the position seen in Figure 1, the position 9
being indicated in Figure 4, then through the fourth quarter, as from the position 9 to
the position 6 Figure 4, the surface of the opening is concentric with the axis E, hence the
arm receives its vibratory movement in one direction, as from the position 6 to position 7,
then the arm will remain stationary from position 7 to position 8, or during the second
portion of the rotation, then under the third portion of rotation, as from the position 8
to position 9, the arm will be returned, and then remain station try through the fourth
or last portion of the rotation, as from the position 9 to position 6, thus the application
of the intermittent rotary-motion is illustrated as a means for producing intermittent
vibratory motion
Instead of the cam shaped opening as the means of communicating the rotary move-
ment of the wheels to the arm, the sides of the opening may be parallel, as represented
in Figures 6, 7 and 8, and instead of a stud to work against the side of the opening at
one point only, as first described, the stud may be enlarged in the form of an eccentric,
as represented in said figures, and so that the rotation of the wheel and the eccentric
will operate through the opening in the lever, and throw it from one extreme to
the other, as from Figure 6 to Figure 8 and return, the central position being
vertical, as indicated in Figure 7, but under this arrangement there will be no
positive rest to the arm or vibrating part, as in the first illustration, that is to
say, in the first illustration the vibratory movement is imparted by the movement
of the reciprocating device in one direction only, when moving in the opposite
direction, the vibrating arm remains stationary, whereas in the last illustration
the vibrating movement in one direction is produced by one half the rotation, and in
the opposite direction by the other half
The lower or free end of the lever L is turned forward over the presser-foot, and
carries an eye P, through which the embroidery thread, cord, or whatever it may be,
is led to the fabric or work, and as usual in this class of embroidery attachments
When the machine is put in operation, the lever will vibrate, so as to take the
embroidery thread or cord across the path of the needle, and so that the needle will
descend first upon one side and then upon the opposite side of the said thread, thereby
laying the needle thread over the cord, as usual in this class of embroidery
attachments
Having now particularly described and ascertained the nature of the said invention
and in what minner the same is to be performed, as communicated to me by my
foreign correspondents I declare that what I claim is
-
First The combination of a pair of gear-wheels B D, of equal size and teeth,
working together, ench wheel provided with radial arms, a reciprocating device
arranged to work in a path between said arms, substantially as described, and whereby
said reciprocating movement in one direction will impart rotation to one wheel, and
that one wheel communicate its rotation to the other wheel, but when moving in the
opposite direction, the said reciprocating movement will impart rotation to the other
wheel, and the said other wheel will communicate its rotation to the first mentioned
wheel, the rotation of the wheels being in the same directon under both operations

page_text: Second In an embroidery attachment for sewing-machines, the combination with a
supporting frame A of two wheels B D, geared together, and provided with
arms F, G, I H, a device connected with and actuated by the needle-bar, arranged
to impinge alternately against said arms, whereby an intermittent rotary movement
18 imparted to said wheels, the embroidery-thread carrier, and means for communicating
motion from said wheels to the thread-carrier, substantially as described
