Improvements in or connected with Embroidering Machines.
I, JOSHUA ENTWISLE, Patent Agent, of the Firm of E. K. Dutton & Co., of Queen's
Chambers, No. 5, John Dalton Street, Manchester, in the County of Lancaster,
Chartered Patent Agents, do hereby declare the nature of this invention (a con-
munication to me by The Kursheedt Manufacturing Company, (Incorporated under
the Laws of the State of New York), of 356 to 360, West Broadway, New York
City, United States of America, Manufacturers), and in what manner the same is to
be performed to be particularly described and ascertained in and by the
following statement and accompanying drawings:-
My said invention relates to improvements in embroidering machines and refers
to various improvements in the construction of such machines whereby the utility of
such machines is greatly enhanced.
In the first place my invention relates to mechanism for disconnecting the
embroidering machine operating mechanism from its driving mechanism, so that opera-
tions other than the needle stitching operations can be effected during such stoppage;
for instance, suppose it is desired to bore out parts of the fabric, then by my device,
the embroidering machine mechanisın can be disconnected leaving the fabric frame
moving mechanism still connected with a prime mover and operative, so that during
the stoppage of the embroidering mechanism the fabric frame moving mechanism
and the boring mechanism may still be operated conjointly.
To this end I have shown in the accompanying drawings an embroidering machine
and a disconnecting mechanism for disconnecting the said embroidering machine
from its prime mover and a Jacquard device for controlling the actions.
And my invention also relates to means whereby the various functions in the
operation of the embroidering machine may be effected and produced by mechanism
under the control of the Jacquard, whereby the movement and also the penetration
of the bore points, the regulation of the tension and the regulation or changing of
the shuttles is effected.
And further my invention relates to means for balancing and supporting the
fabric frame of the embroidering machine.
My invention will be more fully understood by referring to the accompanying
drawings wherein I have shown inechanism embodying my invention.

In the first place I will refer to the disconnecting mechanism for disconnecting the
embroidering machine from its source of power without disconnecting the Jacquard
mechanism therefrom.

page_text: In the drawings, Sheets 1 to 5 inclusive A is an embroidering machine provided
with any usual needle or shuttle driving mechanism such as B, which embroidering
machine is driven from a main shaft or prime mover C through the medium of a
sprocket wheel D which is geared to another sprocket wheel E on a driving shaft F
of the embroidering machine by means of a suitable sprocket chain G or otherwise.
The sprocket wheel D is carried loosely upon the shaft C which also carries a
cam C which is provided with a cam groove c and by referring to Fig. 5 it will be
noted that the sprocket wheel D is provided with a pivot c¹ which carries a latch c²
having a trip and engaging with a pin on the cam C: The latch c² is recessed
at c' to fit over the pin d and is provided with recesses cinto which recesses a
spring bolt c' enters to hold the latch in either of its extreme positions, as will be
explained. This latch c' co-operating with the pin d serves to couple or uncouple
the cam and the sprocket wheel D, so that by working the latch the said cam C¹ can
be coupled or uncoupled from the sprocket wheel, and it being remembered that the
cam C¹ is secured to the main shaft C the embroidering machine will be connected or
disconnected from the said main driving shaft or prime mover C. The means for
effecting the coupling and uncoupling will now be described.
:
Supported in bearings on the frame A is a three-armed lever I which is shown in
Fig. ns of considerable length. This three-armed lever K is shown clearly in
perspective in Fig. 7. One of its depending arms is provided with a sleeve k¹ (see
Figs. 4 and 7) in which a stem works. Thin stem connects with a crescent
carried by the lever K for entry into the cam groove c of the cam C¹, and is slotted
at to receive a stud 2 on a Jacquard rod. This Jacquard rod is operated by
the Jacquard to enter or remove the crescent from the cam at the proper times;
and to enter the stem of the crescent into a hole or to secure it in position'
to re-enter the cam so as to render the mechanisin operative. The depending arm k
of the three-armed lever K is in such position as to strike the trip of the latch c
when the arm has been swung, as will be explained. The arm is shown as provided
with an arc ³ notched at 7 to receive a latch 3 which, entering either notch,
serves to hold the three-armed lever stationary, so that the crescent will be properly
positioned for entrance into the cam. The restoring mechanism for the latch c² is,
shown as consisting of an arm I projecting into the path of the latch c² to restore the
same, as will be explained. Having got thus far, it will be profitable to explain the
action of the parts heretofore described, in order that the subsequent explanation of'
their interaction with the other parts may be fully understood..
This operation is as follows.
We will suppose the shaft C to be rotating and the latch to be in the position;
shown in Fig. 5 when it will couple the cam C' and the sprocket wheel D so that
from the said shaft C, cam and sprocket wheel, the shaft F will be driven, thereby
driving the embroidering machine. When it is desired to disconnect the embroider-
ing machine from its driving mechanism the Jacquard acts to reciprocate the rod k².
entering the crescent ³ into the cam groove c of the cam C¹ and as the cam revolves
the three-armed lever K will be swung to the left bringing the arm into position
to strike the trip c³ of the latch to swing the same free of the pin d on the cam C¹ so
as to swing the latch on its pivot into such a position as to engage the notch co with
the spring bolt or latch c' thus holding the latch clear of the pin d and allowing the
cam to run free from the sprocket wheel, so that the shaft C will revolve the cam
without producing any motion of the sprocket wheel, and hence, the embroidering
machine being deprived of its power, will stop. This stopping, however, should be
gradual and should be brought about in a certain and positive fashion so that the
parts will always stop in the same position ready for re-engagement with the cam.
This is effected in the present instance by suitable stopping mechanism, which will
now be described.
Secured to or made integral with the sprocket wheel I) is a gear J which rotates
with the said sprocket wheel.
-
Working vertically in guides a¹³ on the brackets A³ of the frame A² is a fraine A
composed of ways a¹ a¹, joined by bars a¹ and carrying a slide a², which slide carries
oppositely placed racks a³ a'.
:

page_text: These oppositely placed racks are adapted to be alternately engaged with the gear J.
The frame A is freely movable vertically on the guides a¹³ and the slide a² is freely
movable laterally on the said fraine so that the rack may be raised and lowered by
raising and lowering the frame and the slide may move laterally on the said frame,
the said racks being as aforesaid rigidly secured to the slide a². Mounted in
proximity to the frame are shafts as a (see Figs. 3 and 8), the shaft as carrying a
cam a entered and working between the ways al a¹ of the frame A at one end
thereof and the shaft a carrying a cam a likewise entered between and working in
the ways a¹ at the other end of the frame. Each of these cams is provided with an
arın aº, which arms are connected by a yoke a10 carrying pins all and a¹².
The third arm of the three-armed lever is provided at its lower end with a
hub 10 which carries a pin " provided with a loose block 12 (see Figs. 3 and 4),
which block enters a slot in the slide a so that when the three-armed lever is swung
as before described, the slide a² and racks will move with it.
One of these racks at a time meshes with the gear J so that the rotation of the said
gear is governed by the action of the cam C¹ on the three-armed lever K, so that when
disconnecting is being effected the arm K swinging slowly to the left under the action
of the cam will gradually decrease the speed of the gear J and consequently gradually
bring the embroidering machine to rest. When the machine starts up again, it is
necessary to disengage the upper rack from the gear and engage the lower rack
therewith. As the gear always turns in the direction of the arrow in Fig. 3, it will
be necessary to engage the lower rack a' with the gear so that as the arm K moves to
the right under the action of the cam C¹ it will impart motion to the said gear J so as
to speed it up from a position of rest to a speed equal to that of the rotating cam C¹
so that when the head of the latch c strikes the arm I, the cam Cand sprocket
wheel D will be running at the same rate of speed and there will be no shock when
the connection is made. This shifting of the rack is effected by turning the
cams aa on little shafts as a to raise the frame A' carrying with it the slide a² and
racks as a. This swinging of the cams a7 8 is accomplished by swinging the
yoke a by means of a three-armed fish-tail lever M pivotted upon an extension 13
of the arm (see Fig. 8). This three-armed lever is shown as pivoted at the
point and provided with arms m m¹ and a fish-tail or wedge-piece m² which
co-operates with either pin all or a¹² to swing the yoke a to the right or to the left.
The various positions of the lever and the pivoted fish-tail piece M are shown in
dotted lines in Fig. 8, the two extremities of the throw of said lever being clearly
shown. As shown in full lines, the arm m² of the fish tail lever has just been actuated
to swing the said fish-tail lever on its pivot to throw the fish-tail piece m² to the
right, thus carrying the yoke a¹0 with it and lowering the slide carrying the racks so
as to mesh the upper rack a with the gear J. When in its opposite or dotted line
position the arm brings the fish-tail lever into contact with the pin a" and the
cam L rotating acts upon the arm m of the fish-tail lever so as to swing the same on
its pivot causing the fish-tail piece m² to push against the pin a to throw the
yoke a to the left, thus raising the slide carrying the racks by the mechanism
described to bring the lower rack into mesh with the gear. I will now proceed to
describe a complete cyle of operations so that the seriatim operations just set forth
may be understood.
We will suppose the parts to be in the position shown in Fig. 2, when the Jacquard
acts and enters the crescent into the cam groove c of the cam C which, rotating in
the direction of the arrow in Fig. 2, causes the said crescent to traverse the said
groove and to swing the three-armed lever K to the left at a progressively decreasing
rate of speed.
As the three-armed lever K swings it brings its arm into a position where it will
strike the trips (see Figs. 4 and 5) of the latch c², thus raising. the said latch clear
of the pin d and engaging the recess co of the latch with the spring bolt c holding
the said latch clear of the pin d. The cam C¹ and the sprocket wheel D have now
been disconnected and the cam C being rigidly connected to the shaft C will revolve
free of the said sprocket wheel which is loose on the shaft. At about the time the

page_text: rest.
latch c² is worked by the arm k, the upper rack which, as will be understood, is
being moved to the left by the swinging arm of the three-armed lever K, will
mesh with the gear J and as the rack moves progressively slower under the impulse and
government of the progressively slower moving three-armed lever K, the said gear
and consequently its connected embroidering machine will be brought gradually to
As the arm is about to reach the left extremity of its swing or stroke, the
fish-tail piece m³ of the three-armed fish-tail lever M is thereby brought against the
pin all and the cam L will come against the arm m of the three-armed fish-tail
lever M and, swinging it upward, will cause the fish-tail piece to thrust the pin all
and its connected yoke to the left, thereby swinging the said yoke into the position
shown in dotted lines and causing the cams a7 a to raise the frame A carrying with
it the slide a² to disengage the rack a³ from the gear J and to engage the rack a
with the said gear, the parts having now come to rest. When the parts have been
brought to rest the crescent has reached about the point in the cam groove cat which
instant the Jacquard again acts to withdraw the crescent from the cam and enter its
stein into a hole to secure it in position. The embroidering machine being brought
to a standstill, any desired manipulation of the fabric frame may be effected and
actions performed on the fabric if desired, for instance bore points may be operated
to pierce the fabric while the embroidering needles no longer operate. It will be
remembered that the three-armed lever K having been moved to the left the crescent
or are carried thereby will have been moved sufficiently far to the left to allow the
latch to drop iuto the notch so that the said arm will be held at the left extremity
of its swing by the latch entering the said notch. When the proper moment
for re-connecting the embroidering machine has arrived, the Jacquard operates at
such an instant of time as to enter the crescent into the rotating cain at the point x
and to withdraw its stem from the hole and at the same time rocking the latch 8
by any suitable means such as the arm Fig. 4 to release the arm from its locked
position. Then, as the cam revolves, it will carry the three armed lever to the right.
The first effect of this movement to the right is to start the wheel J through the
medium of the rack at and as the speed of the arm K gradually increases, the speed
of the rack a connected thereto and wheel J meshing therewith will likewise gradually
increase until in a few tenths of a second the wheel J is being driven at the same
rate of speed as the cam C¹ at which instant the latch c² carried by the sprocket
wheel D which moves with the gear J, will be just passing under the arm I, which
arm will force the said latch inward at the proper instant to engage the said latch c²
over the pin d on the cam so that the sprocket wheel D. and the cam C¹ are now
again coupled. The last part of the movement of the arm K serves to bring the slide
to rest and to bring the fish-tail lever into position (see Fig. 8) to be struck by the
rotating cam I. to throw the yoke ao into the position shown in Fig. 3 where the
racks will be completely disengaged from the rotating gear, but will be in such a
position that the upper rack will engage the said gear when the lever / shall again
begin to move to the left in obedience to the action of the Jacquard. As soon as
the yoke has been thrown, as just described, the Jacquard operates to withdraw the
crescent from the cam C' and enter the stem in a hole to receive it so that the
embroidering machine will proceed to do its work in the ordinary manner until at a
predetermined time the Jacquard again acts to set the disconnecting mechanism into
operation.
I will now describe with reference to Sheets 6 to 9 of the drawings my.
improvements for effecting the movement and penetration of the bore points, the
regulating of the tension and the regulation or changing of the shuttle from a
common source of power.
In the drawings Sheets 6 to 9, A indicates the main frame of the embroidering
machine, B is the main driving shaft upon which the main driving cam C is mounted,
D is the shuttle operating shaft, E the tension regulating shaft and F the bore point
moving shaft.
This part of my invention has for its object to produce mechanism for effecting
the operation of these several parts from the Jacquard. The Jacquard mechanism,

page_text: which may be of the construction shown in the Specification of Letters Patent
No. 21361 of the 6th November 1894, is not here shown but it will be understood
that bars or connections may be run from the connectors of the said mechanism
shown in the Specification of the said Patent, so that the various operations
hereinafter set forth may follow from actuating the said bars. by means of the
Jacquard.
I will first proceed to describe the connections from the main cam wheel C, which
move and regulate the bore points. It will be understood that as heretofore devised,
bore points were designed to enter a fabric stretched upon a tambour frame and to
be withdrawn therefrom. My present invention contemplates causing the bore
points to approach the fabric to the working position with a long forward stroke;
then to receive one or more short oscillations while in the fabric in order to clear out
the hole and to withdraw the bore point from the fabric to the working position,
which last named operations may be repeated ad libitum; and then to be withdrawn
from the working position by a long retractive stroke. In order to do this, I have
provided one side or face of the main driving cam C with a cam path c which
receives the bowl g carried on an arm g¹ of the three-armed lever G. When the bore
points are intended to be inactive, the bowl gis in the position shown in Figs. 9.
and 10 and is only entered into the cam c when the bore points are to be actuated.
This bowl enters the cam at about the point 1 (Fig. 20) and between the points I
and 2 the movement of the cam causes the bore point to enter the fabric. Between
the points 2 and 3 the bore points make two short oscillations and between the
points 3 and 4 the bore points are withdrawn from the fabric. The bore points f
are moved from the shaft or bore point mover F, which is oscillated by the arm H,
which in turn is swung by the link or rod h which is engaged with the arm g2 to the
three-armed lever G. This three-armed lever G is also provided with an arm g³
which is provided with a sliding crescent g' which is slid into or out of the cam c¹
by means of the Jacquard, as will be readily understood. When it is desired to
actuate the bore point the crescent g4 is slid into the cam c¹ which thereupon swings
the three-armed lever G on its pivot far enough to bring the bowl into the cam c
on the opposite face of the main driving cam, so that the oscillations which have
been described will be imparted by the said cam to the shaft F through the medium
of the arm g², rod and rocking arm H.
It is frequently desirable to change the amplitude of the vibrations of the bore
points, which in the present instance I have done by shifting the lower end of the
rod h so as to engage it near to or farther from the centre of the arm g³.
Referring particularly to Figs. 9, 10, 13 and 14 it will be noted that the
end of the arm g2 of the three-armed lever G is perforated forming a series of
apertures go, g', I³, Iº, I¹º, g¹¹, g, with which a pin ¹ carried on the lower end of the
rod may be engaged.
When the pin on the rod is entered into the hole 9%, the oscillations of the
said rod will be shorter than when the said pin is engaged with the outermost hole g¹²,
inotions of intermediate extent being imparted to the said rod by engaging the pin
with the intervening holes g7 to g". This rod, in addition to its up and down move-
ment, may likewise be shifted laterally by the Jacquard to engage its pin h² with the
teeth of an oscillating bar I. This lateral shifting may be effected by the
connection h³ running to the Jacquard and engaging with the arm h, as clearly
shown in Fig. 14.
This oscillating bar I is likewise provided with ears to which are pivoted inclined
teeth which are held yieldingly inwards by means of the spring i engaging studs 2
on the said yielding teeth. This bar I extends upwards and across the machine and
is oscillated backwards and forwards by a swing arm of a three-armed lever J carried
on the shaft and having depending arms for engaging in the cam c¹ of the
main driving cam C. The operation of so much of my device as I have now described
is as follows.
When the bowl g is entered into the cam, the rock shaft F governing the bore
points will receive oscillations of varying amplitudes, which oscillations will be constant

page_text: as long as the pin his entered into a hole of the arm g of the three-armed lever G.
When, however, it is desired to increase or decrease the amplitude of the vibrations,
this may be done by adjusting the lower end of the rod h along the arm g² as
follows.
If it is desired to shorten the vibrations the Jacquard is made to act at the proper
instant to move the lower end of the rod laterally to remove the pin from a hole in
the aring and enter the pin 2 into one of the slots between the teeth i of the
reciprocating rod or connection I when the said rod or connection is moving to the
left, as shown in Figs. 9, 10 and 13.
This movement of the oscillating rod or connection I is just sufficient to carry
the lower end of the rod from one hole go to an adjacent hole g³. When this
shifting has been accomplished, the Jacquard again acts to insert the pin h into the
hole which it is now opposite, so that further movements of the bore will be of less
amplitude.
By suitably arranging the Jacquard, the lower end of the rod may be moved in
either direction step by step within the limits of the arm and when the rod h
reaches either extremity of its adjusted positions, the pin is entered into
the inclined slot of the yielding pivoted teeth is so that should further adjustment be
attempted, no damage will ensue.
I will now proceed to describe the parts which constitute the shuttle changing
inechanism and will have special reference to Figs. 9, 10, 15, 16 and 17.
In these Figs. K is a two-armed lever whose lower arm is provided with a
crescent (see Fig. 15) and whose upper arm ³ is connected to an upright rod or
connection which is shown as provided at its upper end with a cam plate 5 (seen
clearly in Fig. 16) which cam plate is provided with a slot ko. On the shaft D of
the machine a shuttle working cam L. is mounted which has two working surfaceз l
and see Fig. 16 each giving a different character of throw to a bowl which may
be engaged with one or the other of the cam surfaces ll, as will be explained. This
bowl is connected to the yoke d which works the shuttle shaft d¹, and is shown as
carried upon an arbor secured in a bracket on the slide 2 of the yoke d. This
bracket is provided with a slide 10 from which projects a pin which enters a
slot in the cam plate k³.
This slide is shown as provided with an angle piece which is entered between
collars on the bowl 7 so as to slide the said bowl along its arbor S. This bowl is
suitably connected to shuttle working mechanism whose action depends upon the
throw given by the cam L, whose action on the bowl depends upon which of the
cims or is engaged by the bowl. Shifting the bowl will engage it with one or
the other of the cams, this shifting, as will readily be understood, being effected as
follows. The crescent is entered into the cam c¹ by the Jacquard and thereupon
the arm is swung by the cam c¹, thereby swinging the arm 13, oscillating the
upright rod and shifting the bowl 17 from one of the cams or to the other.
The tension regulating shaft carries an arm e with a block e¹ sliding in the arc e² of
the ordinary secondary take-up bar mechanism and is controlled by the lever M to
which is connected a rod m, clearly shown in Figs. 9 and 10 and in considerable
detail in Figs. 11, 12 and 18. The free arm of this link is provided with a series of
apertures mm² m³ m³ m³ and with a pair of yielding pivoted teeth m' which are
provided with studs m' and are held in place by the spring m³.
These pivoted teeth are provided with inclined faces mo. This free end of the arm
extends into proximity to a pin m10 on the arm j, and is embraced by a forked arm N
which is provided with a guiding pin n passing through a bracket a on the frame A
of the machine. The arm N is shown as extending downward and provided with an
extension n' which leads to the Jacquard, so that the Jacquard will operate to shift
the arm N laterally carrying with it the lower end of the rod or bar in to move the
said lower end of the rod, to enter the pin mo into one of the apertures m¹ m³ and
so on of the said bar.
In this manner when it is desired to give the lever M an oscillating motion to
adjust it, the Jacquard operates to shift the said rod or link m laterally to engage it
with the pin m¹º of the constantly vibrating lever J.

page_text: '
Opposite to the pin m10 is a standard a carrying pins a³ a', which are spaced far
enough apart to enter adjacent holes m³ m' and so on, of the lower end of the link m
and when the Jacquard operates to shift the lower end of the said link m off the
pins a a, it moves the same on to the pin m10 for the purpose of engaging the link m
with the pin mo on the swing lever J. This may be done while the lever J is at
either extremity of its swing, so that if it be desired to adjust the link m to the right
the Jacquard is so operated as to shift the link m off the pins as a when the lever J
is at the left extremity of its swing and on to the pin m10, which swinging to the
right will carry the link m to the right, thus adjusting it. This adjustment of the
link is to an extent equal to the distance between the centres of adjacent
holes m¹ m² m³ and so on, so that when the adjustment has been effected, the link m
may be again shifted by the Jacquard to enter the pins as at into a pair of holes mm.
Adjustments to the left may be similarly effected by timing the shifting of the link m
to an instant when the lever J is at the right extremity of its stroke. This adjustage
of the lever may be effected as often as desirable by first moving the link m into
engagement with the pin m10 and then back into engagement with the pins a³ ³, the
teeth m providing against any breakage which might occur in case of false adjust-
ment. It will be understood that the various parts of the mechanism constituting
iny invention may be and are used in an ombroidering machine irrespective of its
character, and that the Jacquard mechanism may be of any desired construction.
The final object of my invention is to provide a mechanism which shall so support
and balance the fabric frame of an embroidering machine, that the motion of the
said frame shall be the same and in the same direction over all parts of the said
frame.
It is well known that as present constructed embroidery frames, although
mechanism has been provided to balance them, are not properly balanced and the
motion of the portions of the frame remote from the point where the Pantograph or
the Jacquard mechanism is attached are not the same in direction or extent as the
motions of the part of the frame adjacent to the point of attachment of the
Jacquard mechanism.
By my invention I obvinte these defects, and have produced an absolutely parallel
motion throughout the entire extent of the fabric frame, by which means the figures
embroidered upon the fabric at a distance from the point of attachment of the
Jacquard device or Pantograph are of the same size and shape as those near to the
said point of attachment, instead of being as at present, of different sizes and
distorted shapes. To the ends named, my invention consists in the construction and
arrangement of devices hereinafter set forth and claimed.
In the drawings in Sheets 10 to 13, A represents the fabric frame of an embroidering
machine which may be connected to a Pantograph or Jacquard mechanism at any
suitable point. Stretched upon the fabric frame is a fabric B with which co-operate
the usual needle carrying bars CD. E is the frame of the machine, which frame is
shown as provided with brackets F G for the support of the fabric frame. Pivoted
at the point on the brackets F of the frame is a lever H, which is shown in the
present instance as an elbow or bell-crank lever.
The fabric frame A is suspended from these two fabric-frame supporting devices,
as follows.
Depending from one end h (see Fig. 24) of the lever H and pivoted thereto at the
point h is a vertical link or suspension-bar or rod J which is pivoted at its lower
end to a bracket K on the fabric frame, and depending from one end i (see Fig. 24) of
the lever I and pivoted thereto at the point i is a vertical link or suspension bar L
which is pivoted at its lower end to a bracket M on the fabric frame. The end ¹ of
the lever H (see Fig. 22) is pivotally connected to a longitudinal connecting link or
rod N which extends to the end i' (see Fig. 22) of the lever I and is there pivotally
connected to the lever I, so that the levers H and I with their connecting rod N
constitute a parallel motion all of whose parts are positively connected together as
by pivots, as shown, so that there will be no lost motion, as in the present type of

page_text: machine wherein the fabric frame is suspended upon rails carried by brackets
connected to the fabric-frame and resting upon wheels upon the suspension device.
This parallel motion suspension device inay be provided with a counterbalancing
device which is shown in Figs. 22 and 23 as a counterbalancing weight O for
counterbalancing the weight of the fabric frame and the parallel notion, which
weight O is carried upon a lever o connected to or made integral with the lever H. By
virtue of this parallel motion and counterbalancing mechanism, it will be obvious that
the fabric frame is supported in a very positive manner, so that a movement of one
end thereof will be faithfully reproduced at the other end, so that where a multiplicity
of similar figures are intended to be worked by the needles, as is usually the case, the
figures will in truth be similar and not more and more distorted as we proceed along
the fabric frame away from its point of connection with the Jacquard inechanisın.
It is obvious that the fabric frame and parallel motion may be counterbalanced
otherwise than by a weight, as for instance, by a spring or tension mechanism. One
form of this spring or tension mechanism combined with a fabric frame of the
embroidering machine and the parallel motion is shown in Figs. 24 to 29.
In Fig. 24 the supporting and parallel motion mechanism are shown as in all
respects similar to the corresponding elements in Figs. 22 and 23 with the exception,
however, that the weight O and lever o are dispensed with and their place supplied
by a counterbalancing spring or tension device comprised in part by springs P Pland
provided with compensating mechanism as will be explained. The construction and
connection of these springs will clearly appear by reference to Figs. 24, 25 and 27.
In these figs. the frame E of the embroidering machine is shown as provided at the
upper left hand corner with a journal or pivot socket Q.
Swinging freely in this journal or pivot socket Q is a yoke R which is provided with
a rounded face or portion S which is seated in the journal or pivot socket Q and has
extending therefrom a bracket T provided with an extension t. The yoke R, bearing
or socket Q, rounded portion S and bracket T are pierced for the passage of a shaft U.
One end of each of the springs P P¹ is connected to the bracket T and the other ends
of the said springs are connected by means of adjusting screws to a crosshcad V
(seen clearly in Figs. 25 and 27), which crosshead is shown as provided with
guide-ways v¹. Connected to the extension t of the bracket T and working in
guide-ways v¹ of the cross head V is a T shaped guide or guide bar W, clearly seen in
Figs. 25, 26 and 27 which guide-bar prevents the cross head V from rotating or
twisting. The shaft U which passes through the yoke and its adjunctive devices is
screw threaded for a portion of its length and carries upon the said screw threaded
portion a threaded nut X to which the lower end h¹ of the lever H of Figs. 24 and 25 is:
shown as pivoted. The end u of the shaft U is shown in Fig. 25 as seated in a cup or
socket Y which is provided with a concave bearing face y, which bears upon a small
circular bulge v² carried by the cross head V. It will thus be seen that as the yoke
is held stationary and the end of the shaft U bears against the cross head, that
motion of the fabric frame will cause the springs P P¹ to be extended or collapseil, as
the case may be, and consequently that the device thus constituted will be a
counterbalanced device for the fabric frame, serving the same functions as the
weighted lever shown in Fige. 22 and 23. For small motions of the frame the springs
are quite efficient and serve the purpose with great exactness. It has been
observed, however, that when the fabric frame is given a greater range of
movement and the springs become extended, it becomes more and more difficult
to extend them further, and consequently some compensation must be made,
which compensation should be proportional to the extent of movement of the
frame, so that the resistance to the movement of the frame will not increase as
the frame is given a greater range of movement, but will at all times be
substantially the same. For this purpose I have provided a compensating
mechanism for automatically controlling the tension of the counterbalancing
spring, one form of which compensating mechanism is shown in Figs. 24 to 29,
which I will now proceed to describe. In these figs. I have shown a plurality of
clutch-members a b. The clutch-member a is provided interiorly with a series

page_text: of teeth a' and is mounted upon or made integral with a sleeve a² which is
carried loosely upon the shaft U.
This sleeve a is circumferentially grooved at a³ for the reception of the edge of a
guiding disc at which is carried upon an arbor a" and pressed outwardly on the said
arbor by a spring as, so that the clutch-member a may have a slight longitudinal
movement on the shaft U, and will be restored to position by the restoring spring aº.
The clutch member b is similarly provided interiorly with teeth b¹, and as in the case
of the clutch member a, is mounted upon or integral with a sleeve 62, which turns
freely upon the shaft U and is provided with a circumferential groove b³ for the
reception of a guiding roller 6* which is carried upon an arbor b fixed in the yoke,
and pressed outwardly by a restoring spring 60, so that the clutch member b may have
a longitudinal movement on the shaft U. These clutch members a bare rotated in
opposite directions by suitable belts or other means continually or periodically.
Keyed or otherwise secured upon the shaft U is a clutching disc or member Z,
clearly shown in section in Fig. 26 and in face view in Fig. 29, which clutching
member or disc Z is provided peripherally with projecting teeth which enter
between the teeth a¹ and b¹ of the clutch members a or bas the case may be, it
'being noted that the lever H, when the fabric frame is moved, imparts a longitudinal
movement to the shaft U, carrying with it the clutching member or disc Z and
engaging the said clutching member with one or the other of the interiorly toothed
clutch members a b.
By reference to Figs. 28 and 29 it will be observed that the faces of the teeth a'
and 6 are wedge-shaped, and that the said wedge or inclined faces of the teeth a¹ b¹
are inclined in opposite directions, so that the sides of the teeth of the clutching
member Z may abut firmly against an abutting face of the teeth a¹ 61, so that the
inclined faces of the teeth a 6 will guide the teeth, which are lozenge shaped
into position, and will form a butt or shoulder for the teeth to bear against.
The operation of this form of my invention will be obvious from the foregoing
description. I would state however, than when any considerable motion of the fabric
frame takes place, the counterbalancing springs are stretched or allowed to contract,
and as their tension varies with their degree of distension, much variation must be
compensated for, which is performed automatically by the movement of the rod U
which brings the clutching member Z of the clutch into engagement with one or the
other of the oppositely rotating clutch members which revolve the shaft U in
.the nut.
