Improvements in Machines for Embroidering Oloth and other
Fabrics.
I ALEXANDER GASS-of 17 College Street South in the City of Belfast, Sewing
Machine Maker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to embroidering machines of the ordinary double-pointed
multiple-needle type in which the needles are furnished with threads of limited
length through eyes at the centre and are transferred from one set or row of
holders or grippers to another whereby the threads are carried through the material
being embroidered and the embroidery frame is suspended and balanced and guided
by a pentograph in the ordinary way.
My invention consists in the mechanism by which the machine is made capable
of being driven by steam or other mechanical motor and its productiveness
considerably increased.
The tensioning apparatus is fixed to the front carriage of the machine and moves
with the needles and is so arranged that, when the proper tension has been given
to the threads, the machine reverses its movement automatically. The apparatus
consists of three horizontal rods swinging on arms and crossing the machine in front
of the needles, one above the threads dropping between the other two which are
below them and, when at its lowest point, locking the two others at their highest
position but being free itself, when pulled by the threads, to rise a short distance
without unlocking them so as to produce a uniform tension.
When the tension has been completed the needles return for another stitch and,
as they approach the embroidery frame, the tensioning rods are made to clear away
from before them. To this end the top rod rises and turns back unlocking the
others and letting them fall and, when descending, raises them again and relocks
them, freeing itself as before.
For reversing the movement of the machine and modifying the travel of the
carriage to the diminishing lengths of the threads I employ a lever pivoted at or
near its centre to the front carriage so that when the top tensioning rod rises on the
completion of a stitch one end of the lever which extends below the arm carrying
such tensioning rod is released and the other end engages a notched or toothed rail
upon the machine and, moving it, thereby acts upon an arrangement of levers,
catches, spindle and springs operating upon a shaft mounted with two friction cones
and, by engaging such cones alternately with a cone upon another shaft, causes the
last mentioned shaft to revolve to the right or left, as the case may be, thus moving
the carriage in one direction or the other. I furnish this second shaft with a worm
which actuates a series of toothed wheels and sections of pinions giving, at the
required times, to the carriages, alternately, travel in the proper directions and
rest at the proper place and, by means of eccentrics or cams, levers, rods and cranks,
opening and closing the holders or grippers at the transfer of the needles from one
set or row to the other when both carriages remain at rest for an instant.
I provide a take-up appliance which catches the threads when fully stretched
and carries them down, in accordance with their diminishing lengths, preventing
entanglement while the carriage is advancing to pass the needles but never tightens
them and always gives sufficient slack for the passage of the needles. It rises when
the carriage resumes its motion and, when the threads are being pulled through but
before the stitch is finished, releases them.

page_text: Instead of arranging and operating the back carriage, as I may do in the way I
have described with reference to the front carriage, I may preferably employ a
back carriage actuated from cams or eccentrics on the back shaft and travelling
only a sufficient distance to clear the needles and allow the work to be moved by
the pentograph for the next stitch.
I also employ a bar provided with a series of Lor T shaped hooks and actuated
by the carriage or toothed rail to lift the threads and form loops by which the
button stitch edging is embroidered or to move such threads aside and prevent
looping.

COMPLETE SPECIFICATION.
Improvements in Machines for Embroidering Cloth and other
Fabrics.
I ALEXANDER GASS of 17 College Street South in the City of Belfast Sewing
Machine Maker 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 :-
My invention relates to embroidering machines of the ordinary double pointed
multiple needle type in which the needles are furnished with threads of limited
length fastened through eyes at the centre and are transferred from one set or row
of holders or grippers to another whereby the threads are carried through the
material being embroidered to the full extent of their lengths and the embroidery
frame is suspended and balanced on pulleys and levers and is guided by a
pantograph in the ordinary way.
My invention consists in the introduction of mechanism by which the machine is
made capable of being driven by steam power or other mechanical motor and
provides means for imparting all the motions of the needle carriages (which are
impelled by bolts and pulleys in the ordinary way) and the holders or grippers and
proper tension to the threads automatically and not by hand as heretofore the
result being greatly to lessen manual labour and increase the productive capacity
of the machine.
In machines of the type indicated, when the threads which form the embroidery
are of limited lengths and gradually shorten at each stitch put through the material
(the amount of thread used up being variable), the machine must be capable of
adapting itself through the tension to the varying lengths thereof in order to
produce proper work: and it will be seen from the nature of the tensioning device
and the means of reversing the motions of the needle carriages provided by me that
I attain this end as by their use the length of travel of the carriage varies with the
length of the threads and the tension thereof is uniform.
The tensioning apparatus is attached to the gripper horns fixed on the front
carriage (or on both carriages when both are made to travel the full length of the
threads) and moves with the needles. It is so arranged that when the proper
tension has been given to the threads the machine reverses its movement auto-
matically. This apparatus consists of three horizontal rods swinging on arms and
crossing the machine in front of the needles, one above the threads dropping in
between the other two which are below them and, when at its lowest position,
locking the two others at their bighest position but being free itself, when pulled
by the threads, to rise a short distance without unlocking them so as to produce an
uniform tension.
When the tension has been completed, the needles return for another stitch and,
as they approach the embroidery frame, the three horizontal rods are made to clear

page_text: away from before them. To this end the top or tensioning rod rises and turns
back, unlocking the others and letting them fall and, when descending, raises them
again and relocks them, freeing itself as before.
I have found, however, in the course of my experiments that I may advantageously,
and I will preferably, dispense with the use of one of the two rods below the
threads, namely, that rod which is nearest to the needles, and I may cause the other
of such rods to clear away from before the needles when these are approaching the
embroidery frame either by a swinging movement as above mentioned or by a
sliding movement hereinafter described and which I prefer.
For reversing the movements of the machine and accommodating the travel of
the carriage to the diminishing length of the threads I employ a pawl-lever pivoted,
at or near its centre to the front carriage (or to both carriages as the case may be)
so that, when the tensioning rod rises on the completion of a stitch, one end of the
lever which extends below the arm carrying such tensioning rod is released and
the other end, dropping down, engages a notched or toothed rail upon the machine
and, moving it, thereby acts upon an arrangement of levers, catches, spindle and
springs operating upon two friction cones or bevel pinions mounted on a shaft and,
by engaging such cones or pinions alternately with a cone or pinion upon another
shaft, causes the last mentioned shaft to revolve to the right or left, as may be
required for moving the carriage in one direction or the other.
I furnish the second shaft with a worm which actuates a series of toothed wheels
and pinions giving, at the required times, to the carriages, alternately, travel in the
proper directions and rest at the proper places, and, by means of eccentrics or cams,
levers, rods and cranks, opening and closing the holders or grippers for the transfer
of the needles from one set or row to the other while both carriages remain
at rest for an instant.
In connection with a back carriage travelling only a sufficient distance to clear
the needles and allow the embroidery frame to be moved for the next stitch as
mentioned in my Provisional Specification I provide a take-up apparatus which
catches the threads when the stitches have been completed by the front carriage
and descends along with them and in accordance with their diminishing lengths, to
prevent entanglement but never draws them and always gives sufficient slack for
the passage of the needles to the back carriage. It rises when the front carriage
resumes its motion and, when the threads are being pulled through but before the
stitches are finished, releases them.
But I have discovered since filing my Provisional Specification that the take-up
apparatus, which I employ only for doubling up the threads and preventing their
entanglement, in its arrangement for the outlet of the threads resembles an apparatus
for drawing the whole lengths of the threads through the material being embroidered
and tensioning them, which was made the subject of Letters Patent of 1890 No. 7031
granted to Rudolph Weiss, and I therefore do not claim to be the inventor or
entitled to the exclusive use of such arrangement except when the same is employed
in connection with a machine having a short stroke or travel of the needle carriage
on one side, to enable the embroidery frame to be moved before the return of the
needles, and a long stroke or travel on the other side, for drawing the threads
through the material.
In my Provisional Specification I have stated that I may employ a back carriage
actuated from cams or eccentrics on the back shaft and having only a short stroke
or travel but I have found by subsequent experience that I may advantageously
dispense with the use of such cams or eccentrics and actuate the back carriage like
the front one by means of belts and pulleys in the ordinary manner which I now
prefer to do and in that case I limit its stroke or travel to about two inches by a
stop on the notched or toothed rail already mentioned or by preventing the lower
end of the pawl-lever hereinafter described rising over the notches or teeth of the
rail in which event I remove the protection boards in front of the embroidery in
order to allow the take-up apparatus to travel up and down and I tighten the
friction bite of the compensating mechanism hereinafter described. By providing

page_text: such means the machine may be made convertible from one mode of operation to
the other, at will.
I also employ a bar provided with a series of L or T shaped hooks and actuated
by the carriage or the notched or toothed rail to lift the threads and form loops by
which the button stitch edging or festooning is produced or to move such threads
aside and prevent looping. The bar is, by obvious means, suspended free above
the threads and in front of the embroidery frame and the hooks drop between the
threads when stretched. When the machine reverses the bar is drawn aside by
the carriage or the notched or toothed rail to let the hooks pass under them. The
bar is then lifted with the threads above the line of the needles so that the needles
may pass through the loops but. I do not desire to claim this arrangement as part
of my invention.
It will be understood that by dispensing with the treadles and crank handle and
substituting belt pulleys and friction cones or bevel pinions with the composite
wheel hereinafter described and adding the tensioning and reversing mechanism
also hereinafter described I may transform the ordinary hand driven embroidering
machine of the type referred to into an automatic machine driven by steam or
other such power.
And by a modification of the composite wheel above mentioned and the employ-
ment of pinions having double saddles in connection therewith and also altering
the motion cams of the take-up apparatus or hooks and attaching them to
the composite wheel I may actuate other types of embroidering machines
automatically.
And in order that my said invention may be fully understood I shall now proceed
more particularly to describe the same and to refer to the figures upon the several
sheets of drawings hereunto annexed the same letters of reference indicating the
same or corresponding parts of the machine and my new apparatus throughout all
the figures.
Fig. I (Sheet 1) is an end elevation of the machine shewing the belt pulley
communicating motion thereto, the worm and shaft for carrying it, the worm wheel,
the composite timeing and driving wheel with part of its circumference void of
teeth, the cam for opening and closing the holders or grippers, a lever and rod for
actuating the eccentric rods, the pinions for driving the needle carriages each
furnished with a saddle, the notched or toothed rail for limiting the travel of the
carriages, a bracket and the spindle employed for actuating the friction cones or
bevel pinions and giving direction to the carriages, the horizontal rods on the right
in position for tensioning the threads and on the left when resting for the return of
the needles, and curved arms carrying adjustable weights to bear on the tensioning
rods and regulate the tension, the pawl lever for reversing the motion of the
carriages and a governing lever and weight for balancing such motion, with the
frame and other parts of an ordinary embroidering machine.
Figs II and III (Sheet 2) are sectional end views of the gripper rail and
horizontal rods, showing holders or grippers each of which is pulling a thread at
different stages through the material being embroidered: also the ordinary guards
and network for protecting the threads. The horizontal rods are shewn on the
left side of the material while out of action; and to its right in Fig. II before
tensioning and in Fig. III while tensioning the threads.
Fig. IV (Sheet 2) is an enlargement of the end arm and bracket carrying the
horizontal rods and shews, by the full lines, their positions before being pulled and,
by dotted lines, when pulled by the threads; also the locking mechanism for
keeping the rods below the threads in position.
Fig. V (Sheet 2) is a sectional side view of the locking mechanism at one end of
the machine.
Fig. VI (Sheet 3) is an enlargement of a holder or gripper and tensioning rod
arm shewing one of the rods below the thread arranged to clear away from
before the needles by a sliding movement and a slotted bracket or guide to regulate
such movement.

page_text: Fig. VII (Sheet 4) is an enlargement of the worm wheel and composite wheel,
the cam for opening and closing the holders or grippers, the lever and rod for
actuating the eccentric rods and the saddles attached to the pinions for driving the
needle carriages.
Fig. VIII (Sheet 4) is an enlargement of the notched or toothed rail, the
tensioning rod arm and the pawl-lever which drops into the rail when the threads
have lifted the tensioning rod and the ordinary wheels on which the carriage runs.
Fig. IX (Sheet 4) is an enlarged plan of the belt pulleys, the bracket and
spindle shewing a clutch and bevel pinion giving direction to the carriages, the
notched or toothed rail and bell crank lever connecting it with the clutch; also
the shaft and worm actuating the worm wheel and composite wheel and the
division of the latter for working the carriages alternately.
Fig. ✗ (Sheet 5) is an enlarged elevation of the holders or grippers and the
material being embroidered, the single rods below the threads supported by sliding
brackets for clearing them away from before the needles; also the tensioning rod
and the take-up apparatus caught upon a thread before bringing it down.
Fig. XI (Sheet 5) is an enlarged view of the holders or grippers and material,
the tensioning rods and take-up apparatus when the needle is being carried towards
the material.
Fig. XII (Sheet 5) is a similar view of the same parts as shewn in Fig. XI
when the holder or gripper is drawing the needle upon a short stroke or travel of
the carriage.
Figs. XIII and XIV (Sheet 5) are a front and end view respectively of the
take-up apparatus when the threads have passed through.
Fig. XV (Sheet 6) is an enlargement of the mechanism for opening and closing
the take-up apparatus and guiding it.
Fig. XVI (Sheet 6) is an enlargement of the mechanism for driving the take-up
apparatus, consisting of pulleys for guiding the belt to which it is attached,
a ratchet wheel on the end of the carriage shaft for shortening the downward
stroke of the take-up apparatus as the threads become shorter and raising it a
little to give out more thread, the pawl which engages the ratchet wheel, a rod for
working a swinging lever carrying the pawl and a weight for disengaging it. A
portion of. the carriage to which the arm is attached being also shewn and
Fig. XVII (Sheet 6) is an enlargement of portion of the carriage shaft shewing
a boss pinched to it with a screw, a section of the swinging lever, the ratchet
wheel separated from the lever by a washer and the pulley carrying the driving
belt; also a leather friction washer, a metal washer and a thumb screw with spring
to regulate the friction.
The belt pulley is driven off a revolving shaft or other motor and communicates
notion to the embroidering machine through the shaft, a, which revolves in one
direction only and carries the bevel pinions, a' and a², running free thereon, to be
alternately engaged by the clutch a³ sliding upon a feather in the shaft, a, in order
to rotate the bevel pinion, a³, in one direction or the other and drive the carriages
to and fro as required.
A spindle, b, supported on a bracket, 61, attached to the frame of the machine
carries two arms forming a bell crank lever, 62, for connecting the clutch, a³, with
the notched or toothed rail, s, and reversing the motion of the carriages. The
shaft, c, is rotated by the bevel pinion a' and carries the worm, c', which actuates
the worm wheel and the composite wheel, d. This wheel d is divided in the
width of the rim into two parts, d' and d² with which respectively the pinions, e,
and e, on the driving shafts of the carriages engage to actuate the carriages
alternately. Half only of the periphery of each of such parts is provided with
teeth so that the contact between the teeth of the wheel and pinion is intermittent
and ceases when the wheel has revolved the pinion a sufficient number of times
to return the carriage from the end of its stroke or travel. Each of the parts, d'
and d, of the wheel, d, is furnished externally with a smooth semicircular rim, f,
which engages a saddle, e, attached to each of the pinions, e and e', for the purpose

page_text: of locking the carriage when returned and for starting it again at the proper time
when required to recommence its stroke or travel. The composite wheel, d, is
provided on its inside face with a groove cam g, for actuating the gripper eccentric
rods through a roller on the end of a lever, g¹, connected by a rod, g², with an
-oscillating lever, g³, having forked ends, 9ª, which receive the studs on the rods
connecting the eccentric cranks and actuate the holders or grippers in the
usual way.
The tensioning rod is attached to the arms which in ordinary cases hear the
wire running across and over the threads and clear it from before the needles by
means of the forked lever attached to the end of the spindle carrying the tensioning
rod arms which engages a stud on the frame of the machine and lifts the tensioning
rod in like manner as the wire is lifted in ordinary machines and as shewn on the
left side of the embroidery frame in Fig. I. The rods h¹ and h' below the threads
are attached to brackets, k, and held in position by a slotted segment / on the end
bracket working free on the boss of such bracket or on the spindle i which carries
all the brackets supporting the rods below the threads and to which also each
bracket k is pinched as shewn in Fig. V. The end bracket carries a tail piece to
hold it in position when the tensioning rod is on the threads. A pin ² fixed into
one of the gripper horns and pressed into a detent in the slotted segment, k', holds
it in position while the tensioning rod h is pulled by the threads and rises as shewn
by the dotted lines on Fig. IV (Sheet 2) tightening the threads, without allowing
them to come into a straight line, and reversing the motion of the carriage by
letting the pawl lever, p, drop into the notched or toothed rail, s, as shewn in
Figs. I (Sheet 1) and VIII (Sheet 4). Another pin, k³, is fixed into the slotted
segment, k, and presses against the tail piece of the end bracket, k, while the
. tensioning rod is on the threads, thereby locking the various brackets which support
the rods, and ³, or the rod h¹ when h' is dispensed with. When I employ a
.sliding support (such as k) for the rod h¹ I fix a roller upon one of the links and 12
connecting such support with the shaft, ', which roller, as the carriage approaches
the material being embroidered, strikes against a slotted bracket or guide, m,
attached to the frame of the machine and pushes back the link and the support k*
with the rod h¹ into the position shewn by dotted lines on Fig. VI (Sheet 3) while
the carriage passes on with the needles and the tensioning rod and the rod h¹ are
cleared away from before the needles as already described. A spring n restores
the link , support and rod h¹ to their previous positions on the outward travel
of the carriages.
The dotted lines on Fig. IV (Sheet 2) shew the change of position of the
tensioning rod, h, when raised by the threads. During the change so shewn the
segment, k, is not affected by the tensioning rod arm but, on the carriage approaching
the embroidery frame, the stud on the frame of the machine engages with the forked
lever attached to the end of the spindle carrying the tensioning rod arm and tilts it
.over. A roller attached to a projection of the end arm and working in a slot in
the segment then disengages the segment from the pin, k², and swings it back,
draws the pin, k³, from the tail piece of the bracket, k, and allows the rods h¹ and ²
(or h' alone when h³ is dispensed with) to fall into the position shewn on the left
side of the embroidery frame in Fig. I.
A slight deviation from a direct line is given to the threads in both arrangements
when the tensioning rod falls upon them as shewn in Figs. II (Sheet 2) and VI
(Sheet 3) in order to impart a soft, uniform tension to them and to enable the
tensioning rod to be lifted by and to tension the threads on the completion of a stitch
as shewn in Fig. III (Sheet 2) while at the same time reversing the motion of the
carriage. The thread is not allowed, while the carriage is being reversed, to form
a direct line between the needle and the material being embroidered lest it should
snap or tear the work. The tensioning rod, h, is stayed by a number of curved
arms, o, o, upon which the adjustable weights, o¹, o', are placed for the purpose of
regulating the tension.
The reversing mechanism consists of a pawl-lever, p, balanced on a pivot, r,

page_text: attached to the carriage and extending in one direction to and below the arm.
supporting the tensioning rod, h, and in the other direction to a notched or
toothed rail, s, supported on the frame of the machine and attached thereto by
studs passing through slots so as to admit of a slight movement in either direction.
into the notches or teeth of which rail the adjacent end of the pawl-lever, p, drops-
when the tensioning rod, h, is lifted by the thread and allows the end below the arm
supporting the rod to rise. On the end of the pawl-lever, p, dropping into a notch,
when the thread lifts the tensioning rod, h, the rail, s, is moved a short distance, say
about half an inch, and the clutch, a³, is shifted to the opposite pinion, a¹ or a³,
thereby reversing the motion of the carriage before the thread assumes a straight.
line and so that it cannot receive any more strain than is produced by the lifting of
the tensioning rod. At the outer end of the rails I place a projection, s¹, for the
purpose of reversing the carriage when the threads have first been drawn out to:
their full length through the material to be embroidered and until they have got
firmly held by the material, after which, the tensioning rod, h, begins to operate
and reverses the carriage at whichever tooth the end of the pawl-lever, p, drops
into when the tension of the thread happens to be completed. A portion of the
top of the rail, s, is plane so that the adjacent end of the pawl-lever, p, may not
be obstructed while the carriage is commencing its outward movement and until
the tensioning rod, A, is again bearing on the threads and holding such end above
the teeth or notches of the rail.
The take-up apparatus consists of a bar, t, attached to a stiffining tube, t¹, and
having openings or niches, 2, 3, to receive the threads when fully stretched..
Between each pair of openings I place a conical guide, t³, to direct the threads
into the mouths of the openings as the take-up bar rises to catch them. A bar, t
within or beside the bar, t, and held by studs passing through slots in it is furnished.
with pins or bolts, to, t, which are carried by it across the mouths of the openings
or niches, t, t, after the threads have entered and are withdrawn again just before
the stitches are completed on the upward motion of the take-up bar. The bar, t*,.
is also provided with openings, t, to receive the threads as shewn by dotted lines
on Fig. XIII (Sheet 5). For actuating the take-up apparatus I employ a
compensating mechanism on the end of the carriage shaft and revolving with it..
This consists of a collar, u, fixed on the shaft and having a swinging lever, u',
moving free, which carries a pawl, 22, to engage with a ratchet, u³, held in position.
on the shaft by a friction bite, and a chain belt pulley, ut, on the ratchet, u³,.
communicates motion to the take-up driving shaft, r.
In order to give slack to the threads and reduce the travel of the take-up
apparatus as the length of the threads diminishes I fix upon the carriage a snug, w
so as to come into contact with a catch, x, pinched to a sliding bar which is
connected with the swinging lever, u', and push the sliding bar forward as the
carriage approaches the embroidery frame. This movement of the sliding bar
causes the pawl, u³, to engage the ratchet, u³, stopping the forward motion of and
slightly reversing the ratchet and raising the take-up apparatus for the purpose of
giving back sufficient slack to the threads for the short stroke or travel of the
carriage. When the motion of the carriage is reversed, the pawl, u?, strikes a pin
on one of the brackets supporting the sliding bar and is thus disengaged, allowing.
the ratchet, u, to again revolve with the carriage shaft. A weight at the outer
end of the sliding bar draws it back at the same time. The catch, x, is adjustable.
for regulating the quantity of thread to be given out for the short stroke or travel.
of the carriage.
A guard or fence, ², may be provided for protection from the chain belt. Upon.
each end of the take-up driving shaft there is an inner pulley, shewn on Fig. XVI.
(Sheet 6) by dotted lines, carrying a perforated belt, 3, over a guide pulley, ³, to-
one side of which belt the take-up apparatus is attached. By means of this belt the
apparatus is lowered and raised. The parallel motion of the apparatus is provided.
for by a guide bar, y, at each end of it and to this guide bar I attach a bracket.

page_text: having a tongue y and weight y pivoted upon it to draw back the bar, t', and
pins, to, to, and release the threads as before described. As the take-up apparatus
rises a roller at the back of the outer end of a connecting rod, , attached to the
bar, t, runs up the incline formed by the tongue, y¹, and, when it reaches the top
thereof and the threads have entered the niches or openings, t², 2, is pulled over to
the inside of the tongue by a spring, 2, on the connecting rod, z, and descends
between the tongue and the guide bar. A pair of rollers is placed on the end of
the take-up bar, t, to reduce friction.
On the opposite end of the machine I place a notched or toothed rail and pawl-
levers corresponding with the rail, s, and lever, p, in order to balance the motions
of the carriages and such rail is held in the required position by a governing lever
and weight, g, which swing on a pivot fixed on the machine and are connected with
the rail by a pin and slot.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I would have it to be
understood that I do not claim as of my invention nor the exclusive use of an
embroidering machine of the double pointed multiple needle type or a take-up or a
tensioning or a reversing apparatus except when the same are constructed specially
and employed according to my invention nor do I claim the use of pantographs,
holders or grippers, gripper-horns, tensioning rods, carriages, notched or toothed
rail, composite wheels, springs, eccentrics or cams, ratchets and pawls, rods and
cranks or any other of the separate mechanical parts which are employed in the
construction, operation and regulation of the automatic embroidering apparatus
invented by me but I claim in embroidering machines of the type above
indicated
