On the cylinder is a small conical or bevel wheel gearing with a double sized
wheel on which is an eccentric which operates two lifters these lifters are being con-
nected at their outer ends to studs or pins, carrying the needle bar case, by the
motion of the small bevel wheel and eccentric the lifters are moved to and fro and
80 moves the needle bar case to which they are connected, and-also-the-needle-bur
ease to which they are connected and also the needle bar and needle backwards

JOHN EDWARD WALSH of Halifax, Leeds and Bradford all in the county of York
Patent Agent and Consulting Engineer IMPROVEMENTS IN SHUTTLE SEWING
MACHINES FOR BUTTON HOLE SEWING Communicated to him from abroad by John
Kayser of Kaiserlautern Palatinate of the Rhine, Germany
I construct the needle bar carrying the needle so as to be actuated by the sewing
machine, and it has have a selfacting and changeable stitch for-stitch forwards, or
backwards, movement in the one or the other definite position so that the needle
at one time pierces the slit of the button hole, and at another time pierces sideways
from the slit into the material to be sewn, and in this way the button hole edge
seam is obtained by mechanism as follows.
On the cylinder is a small conical or bevel wheel gearing with a double sized
wheel, on which is an eccentric which operates two lifters, these lifters are being
connected at their outer ends to studs or pins, carrying the needle bar case, by the
motion of the small bevel wheel and eccentric, the lifters are moved to and fro,
and so moves the needle bar case, to which they are connected, and also the needle
bar and needle backwards and forwards giving the zigzag motion required for
button hole sewing.
When wishing to change to ordinary sewing by loosening a screw in a slot and
drawing the apparatus to the right the bevel wheels are thrown out of gear the
screws are then tightened and the studs and needle bar case are secured.
Such being the nature and object of this my said invention in order that the
same may be fully understood I have hereunto annexed one sheet of drawings
illustrative thereof.
I attain these objects by mechanism illustrated in the accompanying drawings in
which,-
Figs 1 and 2 of the drawings show one construction of the machine.
Figs. 3, 4 and 5 of the drawings show a modification of the above.
It will be seen by Figs. 1 and 2 that axle a is provided with a conical bevel
wheel b, which gears with another bevel a wheel c, of double its size, on wheel c, is
the cam eccentrie d, over which the two levers e, are drawn. These levers e, by
their ends being connected with bolts or studs f and the bolts are being connected
with the casing g of the needle bar h, by the rotation of the conical-wheel by and
by the movement of the eccentric-d-the-levers-c, or rather it follows that as the
bolts are drawn to and fro, by the rotation of the bevel wheels which rotate the
cum à which actuates the levers e, the same movement is imparted to the needle
bar easing-serewed to the bolts must of course follow this to and fro movement
giving thereby to the needle bar / that bears the needle, sometimes-the-one-and
sometimes the other position, both necessary for making the bordering stitch of the

page_text: button-hole and needle which thus makes one stitch through the material being
seun, and one stitch through the slit of the button hole. For disengaging this
apparatus in order to employ the ordinary stitching apparatus, the slacken screw i
must be slackened and also the pointed screws l whereby the bolts and the needle
bar-ensing again-are-conveniently fastened. Fig 1 tightened the former provides
for the play of the levers, while the latter prevents the stud f moving.
The pivots o on which the levers e turn may be fixed or adjustable; in the latter
case they are, as shown in Fig. 1 each mounted on a slide 1 the pin n of which
takes into an excentric slot of the disc m; by rotating the latter the slides 1
and thereby the pivots o of the leverse may be brought nearer to or moved farther
from the axis of the cam d. For this purpose the levers e are slotted at o. When
the pivote o are fixed, as shown in Fig. 2 the ends of the levers must be slotted.
It follows that by rotating the disc m the proportions of length of the levers e and
consequently the to and fro motion of the needle bar casing can be altered.
Figs 3, 4 and 5 of the drawings sheow modifications of the above described
invention, the needle bar a (for distinction marked here a) is also placed in a
moving casing connected with made-moveable-by-means-of the studs bolts b (marked
BO for distinction); the bolts studs b carry the boxes ce with the cylindrical pistons,
therein, which pistons are perforated, rectangular to the-axis, into these holes,
eatch-the bolts-of-levers-dr-the rivetted on the ends of the levers d, the latter being
provided with studs or projections Fig 4 and the boxes c are being provided with
suitable slots or eonveniently-made cavities in order to secure free motion to the
studs belt. On the main axle behind-the heart is fastened a bevel eonieal wheel i
which gears with another bevel eonical wheel jb of double its size, the wheel hj on
its backside is provided with an-eccentrical cam groove h, in which engages the
roller p, fastened to the dovetailed sliding piece g, the levers d, d, engaged at one
end are-eneased,-and-are with the studs b attached by means of moveable pins frfs
the-levers-dr-d-eatch-at-the-one-side-on-the-guides-b,-b, of needle bar a, and at the
other side they are connected by the studs f with the moveable sliding piece g, g
in the middle they are supported by the eramps-c-c-by-moving of wheel h, the
sliding piece by means of groove-and-runner-p-will be-displaced this movement is
transmitted-by--levers-d-d--on-needle bar a which now goes to and fro, (the
maximum-way-xx) pivotted sleeves e e. As the wheel j revolves motion is imparted
to the sliding piece g by the roller p running in the cam groove h and thence
through the levers d to the studs b and needle bar a, which thus receives a motion
similar to that described above. Tthe wheel i being only of half the size of
wheel jh, the roller p passes the greater bend of the groove h, during a complete
rotation of the main axle and it passes the smaller bend of the groove during the
next rotation.
The position of the needle bar varies with the corresponds to both positions of
the roller p the-first one as shewn in the drawing and the second displaced-to-the
right-hand, moved to the opposite side of the space provided for it in In order
to alter the width of the bar sewing, the horizontal movement of the needle
bar, is made adjustable by means of conveniently arranging the position distance
of the turning points e, e,; the pins of the sleeves eramps are arranged in the
slides k, k, which are provided with racks opposite to one another, with the small
pinion between and gearing with both, between the racks is placed-a-small
driving gear-l-of which Tthe neck pin of this pinion 1 projects through the
: plate m, specially screwed to it and carries the a small adjustingable lever n by
turning the lever round to the left, the driving gear 1-brings the two racks one

opposite directions thus increasing the distance between the turning centres c c,

Having thus fully described and particularly ascertained the nature and object
of this my said invention, and the manner in which the same may be performed or

page_text: carried into effect I would have it understood that what I claim as the invention
to be secured to me by the hereinbefore in part recited Letters Patent is,-

Patent Agent and Consulting Engineer IMPROVEMENTS IN SHUTTLE SEWING
MACHINES FOR BUTTON HOLE SEWING. Communicated to me from abroad by John
Kayser of Kaiserlautern Palatinate of the Rhine, Germany
I construct the needle bar carrying the needle so as to be actuated by the sewing
machine, and it has a selfacting and changeable stitch for stitch forwards, or back-
wards, movement in the one or the other definite position so that the needle at one
time pierces the slit of the button hole, and at another time pierces sideways from
the slit into the inaterial to be sewn, and in this way the button hole edge seam is
obtained by mechanism as follows.
On the cylinder is a small conical or bevel wheel gearing with a double sized
wheel, on which is an eccentric which operates two lifters, these lifters are connected
at their outer ends to studs or pins, carrying the needle bar case, by the motion of
the small bevel wheel and eccentric, the lifters are moved to and fro, and so moves
the needle bar case, to which they are connected, and also the needle bar and
needle backwards and forwards giving the zigzag motion required for button hole
sewing.
When wishing to change to ordinary sewing by loosening a screw in a slot and
drawing the apparatus to the right the bevel wheels are thrown out of the
gear
screws are then tightened and the studs and needle bar case are secured.
Such being the nature and object of this my said invention in order that the
same may be fully understood I have hereunto annexed one sheet of drawings
illustrative thereof.
I attain these objects by mechanism illustrated in the accompanying drawings in
which,―
Figs 1 and 2 of the drawings show one construction of the machine.
Figs. 3, 4 and 5 of the drawings show a modification of the above.
It will be seen by Figs. 1 and 2 that axle a is provided with a conical wheel b,
which gears with a wheel c, of double its size, on wheel c, is the eccentric d, over
which the two levers e, are drawn, these levers c, by their ends being connected
with bolts or studs fand the bolts are connected with the casing g of the needle
bar h, by the rotation of the conical wheel b, and by the movement of the
eccentric d, the levers e, or rather the bolts fare drawn to and fro, the needle bar
casing screwed to the bolts must of course follow this to and fro movement giving
thereby to the needle bar that bears the needle, sometimes the one and sometimes
the other position, both necessary for making the bordering stitch of the button
hole. For disengaging this apparatus in order to employ the ordinary stitching
apparatus, slacken screw i and also the pointed screw whereby the bolts and the
needle bar casing again are conveniently fastened.
Figs 3, 4 and 5 of the drawings shew modifications of the above described
invention, the needle a (for distinction marked here a) is also placed in a
casing made moveable by means of the bolts (marked so for distinction) the
bolts b carry the boxes e with the cylindrical pistons, therein, which pistons are
perforated, rectangular to the axis, into these holes, catch the bolts of levers d, the
boxes being provided with conveniently made cavities in order to secure free
motion to the bolt. On the main axle behind the heart is fastened a conical
wheel which gears with another conical wheel of double its size, the wheel h, on

page_text: its backside is provided with an eccentrical groove, in which engages the roller p,
fastened to the dovetailed sliding piece g, the levers d, d, are encased, and are
attached by means of moveable pins f, f, the levers d, d, catch at the one side on
the guides b, b, of needle bar a, and at the other side they are connected with the
moveable sliding piece g, g, in the middle they are supported by the cramps c, c,
by moving of wheel h, the sliding piece by means of groove and runner p will be
displaced this movement is transmitted by levers d, d, on needle bar a which now
goes to and fro, (the maximum way x, x,) the wheel i being only of half the size of
wheel h, the roller p passes the greater bend of the groove, during a complete
rotation of the main axle and it passes the smaller bend of the groove during the
next rotation.
The position of the needle bar corresponds to both positions of roller p the
first as shewn in the drawing and the second displaced to the right hand, in
order to alter the width of the bar sewing, the horizontal movement of the
needle bar, is made adjustable by means of conveniently arranging the distance
of the turning points e, e, the pins of the cramps are arranged in the slides k, l,
which are provided with racks opposite to one another, between the racks is placed
a small driving gear of which the neck pin projects through the plate m, specially
screwed to it and carries a small adjustable lever n by tuining the lever round to
the left, the driving gear brings the two racks one from another widening thus
the distance between the link points K, K, thereby the arms of levers d, become
unequal and the movement of the needle bar will be shortened,
l
Having thus fully described and particularly ascertained the nature and object
of this my said invention, and the manner in which the same may be performed or
carried into effect I would have it understood that what I claim as the invention
to be secured to me by the hereinbefore in part recited Letters Patent is,―
1 The displacing of the needle bar by means of eccentrics d which give to the
levers e an oscillating movement and touching the guide bolts f, push alternately
to and fro the needle bar guide g, by means of the wheels, as shewn and described.
2 The application of guide piece g, g, with roller p in combination with the
eccentric groove in the toothed wheel for moving the lever d, as shown and
described.
3 The changing of the turning points e of levers d by means of the racks on the
slides, , in combination with gear moveable from without by means of lever n
as shewn and described.

hand and seal this seventh day of February in the year of our Lord one
thousand eight hundred and eighty three
