Improvements relating to Driving Gear and Stopping and Starting
Devices for Sewing and other Machines.
I, DONALD NOBLE, of 11 to 21, Paul Street, Finsbury, in the County of
London, Engineer, do hereby declare the nature of this invention to be as
follows:--
This invention has for its object further improvements relating to frictional
driving gear of the kind described in the Specification of Letters Patent No. 4770
of 1897 granted to Thomas Robert Rossiter and myself, and is particularly
intended for application to power driven sewing machines which require to be
stopped after each single stitch is made, as when doing "fanning work for
example, or after a definite number of stitches have been taken. The said inven-
tion may however be applied to other machines that require to be driven
intermittently.
By my present invention I utilize the momentum of the rotating parts for the
purpose of applying a brake to such parts after the disconnection or release of
the driving clutch has been effected. The brake is applied with a force which
is proportional to the momentum of the moving parts, and it ensures the stoppage
of the machine with the moving parts in some definite and pre-arranged position,
and without shock to the machine.
In sewing machines for doing fanning work the release of the driving
clutch and the application of the brake occur after every complete revolution
of the main spindle of the machine, but where a number of stitches have to be
taken before a stoppage occurs the parts for releasing the driving clutch and
applying the brake are controlled by a special device which only allows them to
act after the required number of stitches have been made.
According to my invention I employ for separating the gripping discs of the
driving clutch and for applying the brake a brake ring arranged concentrically
with respect to the driving spindle and having on one side of it inclined faces
which bear against corresponding inclined faces on a fixed or stationary part of
the machine, the other side of the brake ring being arranged to make contact
with the projecting heads of the screws that hold the gripping discs together.
In some instances I interpose a loose ring supported by balls or rollers between
the heads of the screws and the brake ring to reduce the friction between them.
When the brake ring is turned slightly the inclined faces aforesaid slide over
each other and the brake ring is thereby moved axially and caused first to press
on the heads of the screws and so separate the gripping discs and then to press
against the revolving disc and stop it. The part of the ring that comes in con-
tact with the revolving disc may be faced with leather or other suitable material.
The brake ring is for this purpose actuated as follows, that is to say, a lever
(hereinafter termed the brake lever) pivoted on an arm of the brake ring engages
at one end with a cam groove in a lever under the control of the operator through
a treadle or otherwise, the other end of the brake lever being arranged in the
path of a cam or projection on one of the driven gripping discs. As applied to

page_text: a fanning machine where only single stitches are required to be made between
the stoppages, the cam groove of the operator's lever is so shaped that when
the said lever is moved, it first releases the brake lever and moves it out of
contact with the cam or projection on the gripping disc and then immediately
brings it back again, but in the interval, the brake ring being released is at once
forced back by the springs on the beforementioned screws and the gripping
discs seize the rotary driving disc and so start the machine. When however
a single revolution is completed the cam on the gripping disc comes again in
contact with the brake lever, presses thereon, and first separates the gripping
discs and then applies the brake. It is the momentum of the moving parts
after the clutch is released that supplies the force for pressing on the brake lever
and so applying the brake.
When a number of stitches are required to be made before the machine is
stopped, the cam groove in the operator's lever is shaped to release and move
the brake lever away from the cam on the gripping disc thus starting the
machine, after which the brake lever is held back by the rim of an intermittently
rotating feed disc, and the machine continues working.. When however a notch
in the rim of the said feed or counting disc comes under the brake lever, the
said lever is free again and is immediately brought back by a spring which acts
on the operator's lever to return the latter to its initial position, whereupon the
cam on the gripping disc at once acts on the brake lever and stops the machine
The feed or counting disc is driven preferably through a silent feed arrangement
from a crank or eccentric and an arm whose position can be adjusted in a slot
so as to alter the relative speed of the counting disc with respect to the machine
and so provide for a fewer or larger number of stitches being made before the
machine is stopped.

Improvements relating to Driving Gear and Stopping and Starting
Devices for Sewing and other Machines.
I, DONALD NOBLE, of 11 to 21, Paul Street, Finsbury, in the County of
London, Engineer, 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 machines generally in which it is required to transmit
power to operating mechanism and to stop and start the operating mechanism
at the will of the operator.
My said invention is especially adapted for use in connection with either
regular or zigzag sewing machines and I have therefore illustrated its applica-
tion to a sewing machine and will describe its uses in connection therewith,
this single application of the invention being deemed sufficient for the purposes
of this specification.
The essential features of novelty are:-An automatic release of the operating
mechanism after each stitch as in "flossing" or
fanning" or after any predeter
mined number of stitches as in the manufacture of clothing; and automatic
brake mechanism which stops the operating mechanism when the latter is released.
the important feature of this brake mechanism being that I utilize the momentum

page_text: of a rotating part for the purpose of applying the brake to such rotating part
after the release, the brake being applied with a force proportional to the
momentum of the moving part thereby insuring the stoppage of the moving part
in some definite and predetermined position and without shock or jar..
In the accompanying drawings which illustrate my invention as applied to a
Wheeler and Wilson sewing machine,
Figure 1 is a front elevation of the machine.
Figure 2 is an end elevation as seen from the right of Figure 1, the parts
being in the normal or stopped position.
Figure 3 is a view similar to Figure 2, the driving pulley, counting disc,
friction feed, and other parts being removed.
Figure 4 is a vertical longitudinal section of a portion of the machine on the
line - in Figure 2.
Figure 5 is a transverse section on the line y-y in Figure 1.
Figure 6 is a perspective view of the driving pulley and of the parts of the
gripping and releasing mechanism, detached.
Figure 7 is a detail sectional view corresponding substantially with a portion
of Figure 4 but showing a modification in construction.
Figure 8 is a view corresponding with Figures 2 and 3, except that the count.
ing disc and link are dispensed with and the cam slot in the operating lever
is so modified that but a single movement of the operating lever is required to
start the machine and to stop it when a single stitch has been formed as in "floss.
ing" or fanning," the parts being in the stopped position.
Figure 9 is a similar view, the parts being in the operating position, and
Figures 10 and 11 are views corresponding respectively with Figures 2 and 3,
showing the parts in the operating position, i.e. a position of the parts while the
upper shaft is being carried by the driving pulleys.
Like letters and figures of referencé denote corresponding parts in the several
figures.
A denotes the arm of the sewing machine; B the bed plate: C the upper
shaft: 1) the lower shaft; E the connecting rod; F feeding mechanism as a
whole; and G stitch forming mechanism as a whole.
It is not deemed necessary for the purposes of this specification to describe the
stitch forming mechanism of a sewing machine in detail, for the reason that
my novel releasing and stopping mechanism is not only applicable to other types
of sewing machines than the one illustrated, but is applicable to any machine
having intermittently actuated operating mechanism.
20 denotes the driving pulley which is loose on the shaft C, or in the present
instance upon a sleeve 21 fixed to a clutch disc 22, which is itself rigidly secured
to the shaft. Power is applied to drive this pulley in any suitable manner as
by a band or belt, not shown. 23 denotes a recess in the inner face of the
driving pulley, and 24 a friction washer, which may be a leather ring, and
which projects from the inner periphery of the driving pulley into the recess.
25 denotes a movable clutch disc lying in the recess 23 and on the inner side
of the friction washer so that in practice the friction washer, carried by the
driving pulley, lies between the movable clutch disc and the. clutch disc 22
which, as stated; is fixed to the shaft. The movable clutch disc is rigidly secured
to and is carried by bolts or rods 26 which pass through the friction washer and
through the clutch disc 22 and whose heads 27 project from the face of said dise,
see Figure 6. 28, 28 denote springs bearing against the under sides of the
heads 27 and against the clutch disc 22 and normally acting to draw the clutch
dise 25 outward so that the friction washer 24, carried by the driving pulley,
will be gripped between the movable clutch disc 25 and the clutch disc 22, and
the shaft to which said disc 22 is fixed will be driven by the driving pulley, it
being understood of course that the distance the movable friction disc moves in
order to grip or release the friction washer is so slight as to be incapable of illus-

page_text: tration in the drawings. In the present instance, I have shown the springs 28
as seated in recesses 30 in the clutch disc 22. 29 denotes a brake ring made
of leather or other suitable material which projects from the face of the clutch
disc 22.
In use, the movable clutch disc is moved inward to release the friction washer
of the driving pulley, by means of a brake disc 31 the face of which is adapted
to engage with or bear against the heads 27. This brake disc is loose relatively
to the shaft, (in the present instance it is mounted on a fixed sleeve 32) and is
adapted to oscillate fliereon and at the same time to move laterally thereon.
This movement of the brake disc is effected by means of inclines 33, "Figures 1
and 6, on the opposite face thereof, which inclines are adapted to engage corre-
sponding inclines 34 on a disc 35 also concentric with the shaft, and fixed to the
machine. In the present instance I have shown the disc 35 as provided with an
arm 36, having at its outer end a slot 87 Figure 3 through which a bolt or
screw 38 passes to lock the part in place, the slot being provided in order that
the fixed inclines may be adjusted to compensate for wear in use. If preferred
a loose ring 39 Figure 7 may be interposed between the brake disc and heads 27.
This ring, may rest upon balls or rollers 40 in a race 41 between the ring and
the brake disc. In use, when the brake disc is turned slightly, the inclines 83
will ride up the inclines 34 so that in addition to its turning movement the brake
disc will be moved inward against the heads 27 forcing said heads and conse-
quently the clutch disc 25 inward away from the friction washer and thereby
releasing the friction, washer from its engagement by clutch dise 22 and 25 and
disconnecting the shaft from the driving pulley. It will be understood that the
first action of the clutch disc as it is moved inward is upon heads 27 to effect
the release of the shaft from the driving mechanism. An instant later, however,
the brake dise comes in contact with the brake ring 29, which projects from
the face of the clutch disc 22, and stops the rotation of said dise 22 and therefore
of the shaft.
The brake disc is actuated to release the shaft and also to stop its rotation in
the manner which I will now describe. 42, Figure 6, denotes a cam incline
extending outward from the periphery of the clutch disc 22, the function of
which I will presently explain. 43 denotes an arm extending from the periphery
of the brake disc to which a brake lever 44 is pivoted. This brake lever is in
shape a bell crank lever the pivotal point being at the angle thereof; one arm
of said lever carries a roller 45, which is adapted to engage with the cam
incline 42, and the other arm carrying a roller 46, is adapted to engage with a
cam slot 47 in an operating lever 48; fulcrumed on a stud 49, the said arm
carrying the roller 46 being also provided with a dog 50 adapted to engage with
a recess 51 in the periphery of a counting disc 52 which is mounted on the
stud 49, as will presently be fully explained.
The operating lever 48 may be actuated by hand or by a treadle as preferred.
When my novel releasing and stopping mechanism is applied to a sewing machine
it will be found convenient to actuate the operating lever by means of a rod 53
extending to a rocking treadle, not shown. The counting disc is not used when
the operating mechanism is stopped after each stitch as in flossing or
"fanning" but when it is required that a number of stitches be made between
each stop the counting disc is an essential element. In practice the counting
disc is actuated by means of a friction feed, which as a whole I have designated
by H and the stop pawl operating in connection therewith by h. This friction
feed, which specifically is not of the essence of my invention as any preferred
style of friction feed may be used, lies in a recess 54 Figure 4 in the outer face
of the counting disc and is itself actuated by means of an eccentric or crank 55
on the lower shaft D), from which a rod 56 extends to a block 57 adjustably
secured in an arc shaped groove 58, in an arm 59 which is made integral with
or is rigidly secured to a part of the friction feed, this part of the friction feed

page_text: being free to oscillate on a sleeve 61 by which the counting disc'is carried and
which itself is free to rotate on the stud 49. The counting disc may be provided
with one or more recesses 51 depending, of course, upon the size of the dise
and the special work to which the machine is to be applied. In the present
instance I have shown the counting disc as provided with two recesses, which
provides for two stops during each rotation of the disc, a stop being effected
when the dog 50 drops into one of the recesses and the parts assume the position
in which they are shown in Figures 2 and 8.
60 denotes a spring the normal action of which is to raise that end of the
operating lever in which the cam slot 47 is formed. This raised position of the
operating lever is the stopping position and is clearly illustrated in Figures 2
and 3, the roller 46 being at the lower end of the cam slot which swings that
arm of the brake lever inward so that the dog 50 will enter the recess in the
counting disc. In this position of the parts, the friction washer 24 carried by
the driving pulley is released, i.e. not gripped by the clutch discs 22 and 25,
so that the shaft will remain stationary. To start the machine it is simply
necessary to throw the operating lever from the position shown in Figures 2
and 3 to the position shown in Figures 10 and 11, the effect of which is to place
the roller 46 at the upper end of the cam slot and to swing the brake lever
outward, withdrawing the dog 50 from the recess in the counting disc so that
the latter is then free to be actuated by the friction feed; this I term the
operating position. The effect of the oscillation of the brake lever just above
described is to oscillate the brake disc 31 and, through the action of the
springs 28, to cause the inclines 33 thereon to ride down the fixed inclines 34
so that the brake disc, as seen in Figures 4 and 7, will move slightly toward
the left, the heads 27 of the bolts 26 following the brake disc and causing the
movable clutch disc 25 to clamp the friction washer on the driving pulley
between itself and the clutch disc 22 on the shaft, so that the latter will be
carried round by the driving pulley. While the machine is operating, the
dog 50 will rest upon the periphery of the counting disc, the operating lever
remaining in the position shown in Figures 10 and Il with the roller 46 at the
upper end of the cam slot, in which position the parts are retained by the
spring 60, the roller 45 now being out of the path of the cam incline. The
instant however that the rotation, or partial rotation as may be, of the counting
disc is completed and a recess 51 is brought into alignment with the dog 50,
the spring 60 will act to throw the operating lever from the position shown in
Figures 10 and 11 back to the position shown in Figures 2 and 3. This move-
ment causes the roller 46 to travel down the cam slot, swings the brake lever
inward again and causes the dog 50 to enter the recess 51 in the counting disc.
At the instant the counting disc has reached a position in which the dog 50 13
in alignment with a recess 51, the cam incline 42 on the clutch disc 22 will have
reached the position indicated by dotted lines in Figure 3, i.e. a position in
which it will be engaged by the roller 45 on the brake lever when the last above
described oscillation of said lever takes place. The effect of this oscillation of
the brake lever is to release the driving pulley and to stop the rotation of the
clutch disc 22 and the shaft in the manner I will now describe.
It should be borne in mind that the brake lever is in fact a bell crank lever,
that the arm 43 extending from the brake disc 31 is pivoted to the angle of said
lever, and that the arm of said lever which carries the roller 45 is, in the present
position of the parts, locked in place through the engagement of said roller with
the cam incline 42 on the clutch disc 22. It follows therefore that oscillation
of the operating lever will impart a toggle movement to the brake lever and
will, through the connection of the arm 43 with the angle thereof, oscillate the
brake disc and cause the inclines 33 to ride up the fixed inclines, the effect of
which is to move the brake disc slightly toward the right, as seen in Figures 1
and 7 against the power of springs 28; so that the clutch disc 25 carried by the

page_text: bolts 26 will be moved away from the friction washer on the driving pulley and
said friction washer will be released from its engagement by said clutch disc,
and clutch dise 22, leaving the shaft disconnected from the driving pulley.
The instant this release of the shaft is effected the rotation of the shaft will be
stopped through the engagement of the brake disc with the brake ring 29
which projects from the face of the clutch disc 22, the action of the inclines
being to press the brake disc against this brake ring with a force proportional
to the momentum of the clutch disc 22. This utilization of the momentum of the
clutch disc 22 to stop its own rotation when it is in a certain definite position
will be readily understood from the fact that the cam incline 42 by which the
brake disc is actuated through the brake lever, is a fixed part of said clutch
disc 22. The momentum of said clutch disc and cam incline is communicated
to the brake lever through the engagement of the roller 45 on said lever with
the cam incline, and the brake lever in turn oscillates the brake disc and the
inclines move said disc laterally, with more or less force, against the brake ring
on the clutch disc 22 carried by the shaft.
The machine is started again by another oscillation of the operating lever,
i.e. throwing said lever from the position shown in Figures 2 and 3 back to the
position shown in Figures 10 and 11. This movement throws the dog 50 out
of the recess 51, releasing the counting disc, and leaving the friction feed free
to act, and also imparts another toggle movement to the brake lever owing to
the fact that roller 45 is still in engagement with the cam incline on the disc 22,
as clearly indicated by dotted lines in Figure 11. The effect of this last described
oscillation of the brake lever is to oscillate the brake disc and permit the
springs 28, which press the heads 27 of bolts 26 against the brake disc, to cause
the inclines on the brake disc to ride down the fixed inclines, moving said brake
disc laterally towards the left and again causing clutch disc 25 carried by said
bolts to clamp the friction washer upon the driving pulley between said clutch
disc and clutch disc 22, so that the movement of the driving pulley will be
communicated to clutch dise 22 and the shaft. The cam incline will now pass
out of engagement with the roller 45, but the parts will remain in the position
shown in Figures 10 and 11 owing to the engagement of the dog 50 with the
periphery of the counting disc until a recess 51 is again in alignment with the
dog and the cam incline is in position to engage the roller 45 on the brake lever
the instant the latter is oscillated through the action of the spring 60 and the
operating lever. This last oscillation of the brake lever oscillates the brake
disc, the inclines 33, 34 again move it laterally toward the right and by engage-
ment with the heads 27 of the bolts 26 move the clutch disc 25 toward the right
and release the friction washer upon the driving pulley, the rotation of clutch
disc 22 and the shaft being stopped as before at the required position and with-
out shock to the machine by the engagement of the brake disc with the brake
ring.
It will of course be understood that the time which elapses between two stops
is the time that it takes for the counting disc to turn far enough to enable the
dog 50 to engage with the next recess 51, if there are more than one, or make
an entire revolution if there is but one recess. It follows therefore that if a
relatively small number of stitches is required between stops, the counting disc
must be moved relatively farther at each actuation, and if a relatively large
number of stitches is required between the stops the counting disc must receive
relatively less forward movement at each actuation of the machine. The adjust-
ment to accomplish this result is effected by moving the block 57, to which the
rod 56 is pivoted, inward or outward in the arc shaped groove 58. To produce
a relatively small number of stitches between stops the block is moved inward
in said slot so as to produce greater movement of the counting disc at each actua-
tion; and if a relatively large number of stitches is required between stops the
block is moved outward in the groove so that the counting disc will receive less
forward movement at each actuation.

page_text: Should it be desired to have the operating mechanism stop after each stitch
as in "flossing" or fanning," the counting disc and the friction feed would be
removed and the operating mechanism would be stopped and started in the
manner already described by means of the operating lever, brake lever, and
clutch discs, it being, of course, understood that an upward and downward move-
ment of the operating lever would be required in order to start the machine and
to stop it again after each stitch. For convenience in operation, where this
form of work only is to be performed by the machine, I preferably use the form
of operating lever illustrated in Figures 8 and 9. This form differs from the
other form only in that the cam slot 47 consists of a double incline instead of
a single incline, and consequently but a single movement of the operating lever
is required to start the machine and to stop it again after each stitch. The
roller 46 travels from one end of the cam slot to the other at each actuation of
the operating lever, the stitch forming mechanism being stopped when the roller
is at either end of the slot and released only when said roller is in the mid position
as shown in Figure 9..
The operation of the machine as a whole is briefly as follows:-suppose that
it is required to make a certain definite number of stitches between stops and
that the counting disc upon the machine is provided with two notches 51, the
block 57 would first be so adjusted in the are shaped groove as to produce a
half rotation of the counting disc by means of a number of actuations corre-
sponding to the number of stitches it is required to make between stops. In
practice the upper side of the arm 59, in which the block 57 slides, is provided
with a scale for convenience in making this adjustment. When the operator
has the work in place and everything is ready, the machine is started by oscilla-
tion of the operating leyer. The automatic action of the releasing mechanism
and the brake to stop the machine when the predetermined number of stitches
has been formed has already been fully explained. The machine is again
started by oscillation of the operating lever as before.
When my novel mechanism is applied to a "flossing" or "fanning" machine,
in which use it is required that the machine should stop after each stitch, the
counting disc and friction feed are of course dispensed with, otherwise the opera-
tion is the same as before. When the operating lever is oscillated it oscillates
the brake lever in the same manner as before and moves the roller 45 out of
engagement with the cam incline 42 on the clutch disc 22 and then immediately
brings said roller back into engagement with the cam incline again, but in the
meantime, through the action of the brake disc, springs 28, and clutch discs,
the shaft will have been engaged and have made a revolution, whereby a stitch
is formed, and have been again released and stopped and will be ready to be
started again by another oscillation of the operating lever, hundreds of stitches
being made in less time than the operation can be described. In the form
illustrated in Figures 2, 3, 10 and 11 the operation of starting and stopping
requires a movement of the operating lever in each direction owing to the fact
that the cam slot is formed with a single incline, but in the form illustrated
in Figures 8 and 9 the cam slot is formed with a double incline, so that a move-
ment of the operating lever in either direction will start and stop the machine,
.e. cause the clutch discs to grip the friction washer on the driving pulley, then
release it and the brake disc and brake ring will act to stop the rotation of the
shaft.
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. A device for driving a sewing or other machine intermittently and for
stopping the same in a predetermined position comprising a pair of clutch discs
which tend to come into driving connection with a loose driving pulley, such

page_text: connection being controlled by an oscillatory and axially movable brake disc
acting to separate the clutch discs and then to brake the rotating parts; sub-
stantially as, and for the purposes specified.
2. In a device of the character described, the combination with a shaft and
a driving pulley loose thereon and having a recess in its face and a friction washer
extending into said recess, of a clutch disc fixed to the shaft and lying on the
outer side of the friction washer, a movable clutch disc lying in said recess on
the inner side of the friction washer, bolts by which the movable clutch disc.
is carried and which pass through the friction washer and the fixed clutch disc
and are provided with heads, springs bearing against said heads and the fixed
clutch disc whereby the friction washer is normally gripped between the clutch
discs, and an oscillatory and laterally or axially movable disc 31 lying in contact
with said heads whereby the movable clutch (lise may be moved and caused to
release the friction washer, substantially as described.
3. The construction of the fixed clutch disc with a brake ring on its outer face
so arranged that immediately the disc 31 has caused the movable clutch disc
to release the friction washer it engages with the brake ring and stops the rota-
tion of the fixed clutch disc and the shaft, substantially as described.
4. The construction of the brake disc with inclines 33 working in combination
with staticnary inclines 34 so that when the brake disc is oscillated in one direc-
tion it will be caused to move axially and will first release the friction washer
and then by engagement with the brake ring will stop rotation of the fixed
clutch disc and shaft, and when it is oscillated in the opposite direction the
springs which control the movable clutch will cause the inclines on the brake
dise to ride down the corresponding fixed inclines, substantially as, and for
the purpose specified.
5. The combination, with the brake disc 81 having inclines 33, of a disc 35
having inclines corresponding with the inclines on the brake disc and means
for adjusting the disc 35 to compensate for wear in use, substantially as described.
6. The combination, with the stopping and starting devices, of a ring 39
between the bolt heads 27 and the brake disc, and a ball-race and balls for sup-
porting the said rings, substantially as, and for the purpose specified.
7. The means for actuating the brake disc, said means comprising an operating
lever having a cam slot a bell-crank lever to whose angle the arm 43 of the brake
disc is pivoted and one arm of which is provided with a roller 45 adapted to
engage with a cam incline 42 on the clutch disc 22 and the other with a roller 46
engaging with the cam slot, so that when the roller 46 is in the operating
position in the cam slot the roller 45 will be out of the path of the cani incline
and when the roller 46 is in the stopping position in the cam slot, the roller 45
will be in position to be engaged by the cam incline, the action of the operating
lever when moved in either direction being to actuate the brake lever with a
toggle movement which in turn oscillates the brake disc, substantially as
described.
8. The operating lever constructed with a cam slot having operating and
stopping positions for the roller 46, and controlled by a spring 60 normally
acting to hold it in such a position that the roller will be in the stopping position
in the cam slot, substantially as described.
9. The brake lever provided with a dog 50. in combination with a counting
disc having in its periphery a recess adapted to receive said dog when the
roller 46 is in the stopping position in the cam slot of the operating lever, the
periphery of said dise being engaged by said dog when the parts are in the
operating position, substantially as described.
10. The adjustable friction feed for actuating the counting disc whereby the
latter may be rotated to place its recess in alignment with the dog 50 by any
required number of actuations, the number of rotations of the disc 22 between
stops being thus determined, substantially as described,

page_text: 11. The improved driving gear and stopping and starting device, substantially.
as described with reference to the accompanying drawings, and operating as
specified.
