Improvements in Machines for Finishing Metal-ended Lacings.
I, CARL PAAS, of Barmen, Rhenish Prussia, Germany, Manufacturer do hereby
declare the nature of this invention and in what manner the same is to be performed,
to be particularly described and ascertamed in and by the following statement
Lacings for shoes, corsets and such like are finished at their ends in a variety
The machine herein to
of ways as by the employment of sheet-metal and wire
be described has been devised for the purpose of automatically finishing the ends
of lacings with wie tips.
In my improved machine the wire taken from a reel by a feeding device has its
ends thiust through the lacing and also preferably through a twisting device, and
the free end of the wue is the cafter caught by a wne pulling-device and drawn
further through the lacing and from the feeding device, the latter at such time
eliding back on the wue to its starting point, after which the wnc is preferably
automatically cut off for the length desired for the twisted end.
The lacing is held in clamp, and the wire having been cut off the twisting
device, holding the wire cach side the lacing, 13 10tated to twist the wire together
from its junction with the lacing, leaving a close twisted tapered end or tip.
Duing the twisting operation the lacing is held firmly by a suitable clamp close
to the point where the wire is doubled in the lacing.
The twisting device is shown as connected to a rotating spindle, means being
provided to change the relativo positions of the clamp and twisting device during
the twisting operation, the change being effected preferably by moving the spindle
longitudinally. I have devised means for hending the wire into staple form after
having been thust through the lacing, said operation being performed by
sliding longitudinally in the twisting device The twisting device is provided with
a spring-controlled jaw-closer which keeps the ends of the jaws pressed properly
one towards the other to ensure the proper twisting of the wie for the tip
or end

The fame work consists essentially of legs A upon which is mounted a
table A¹ which through suitable columns erected thereon, supports a bed-plate A³
the latter having sustained above it by suitable posts a a top plate A.
The table A has suitable bearings for the main shaft A having fast upon it
at one end a crank A provided with a crank-pm A over which is fitted a
link An turn fitted to a stud A8 OD ack A which is reciprocated up and
down, intermittingly with periods of test between each motion, in a suitable
gude way made a stand A secured to the bed plate A'
The stand A contains beatings for a short shaft a upon which is fixed a
pinion a engaged by said rach, said shaft having a toothed gear a³, which, see
Fig 3 engages pin on a on a second shaft, having beaugs in said frame, said
shaft having also applied to it a toothed gear a, which engages the long
pinion a fast on the twisting-spindle B, to be described, said pinion being made
long, in order that the engagement of the gears a' a' may be maintained and
cause the rotation of the spindle even when the latter is being moved longi-
tudiually as will be described, the said gearings imparting 1otation to said spindle
in one direction, while the wire for the tip is being twisted firmly together by the
twisting device to be de-cubed and then the spindle is revolved in the opposite
dnection back to its starting point as will be described.
The spindle B has fast upon it a threaded call ir B which is embraced by a
threaded nut B2, preferably made as two part stand, having its feet bolted by
bolts B', see Figs 3, to the top plate A³
The spindle B slides back and forth in a bearing 13 suitably bolied to the
top-plate
The spindle B at its front end has attached to, or made as part of it, a head B,
which serves to sustain the stud 17 constituting the fulcium for the jaws of the
twisting device or grippers 13 herem represented as having detachable pose-
pieces B provided with holes at B which are in line, when the jaws nie closed
upon a lacing, said holes serving to receive through them the wire W on its way
into and beyond the lacing, preparatory to being twisted into the form of
a tip
The inner ends of the jaws B receive pins 13" which join them to huks B in
tuin jointed to a coliai B loose on the spindle B said collar being connected by a
sping B to a più of projection Be on the head B, said spring normally acting
to pull the collar in the direction of the autow next it in Figs 11 and 12, to thus
effect the closing of the jaws of the twisting device upon the lacing and next to
bo tipped.
The collar BH is shown as rounded and at suitable timics after the spring has
acted to close the twisting device upon the lacing, a slide B, see Figs 3 and 22
is thrown forward with its preferably rounded end against the rounded rear end
of said collar, thus moving the same positively in the direction to cause the jaws

page_text: of the twisting device to grip the lace positively while the wire W is being
inserted through the holes B as will be described, the conect alignment of the
holes with the point of the wire being maured by the action of a plunger C guided
in a stand C secured to the upper side of the top-plate, see Fig. 3 and 21, said
plunger having a roller or other stud which is acted upon by a cam C' which causes
the plunger to contact with a flat o secaut face of a collar c¹ fast on the
spindle B
The slide B has at one side a collu or other stud see Fig 22 which enters a
suitable cam groove in 21 cam disk Bx fast on an intermittingly rotated
shaft du
The stand B has erected upon it a catch C, composed, as herem shown, of a
sping arm having an attached notched block shaped to constitute a hook, see
Fig 1, to engage and stop the collar B just about as the spindle B, then being
otated in one dnection by the ack A and being slid longitudinally by the
thi ended uut B, comes into the position to have the jaws of the twisting device
clamped upon the end of a lacing, the engagement of the catch with said collar
sei ving to quickly open the jaws of the twisting device in order that it may straddle
the lacing end preparatory to being closed thereon.
As soon as the spindle B has been moved sufficiently forward and the jaws have
been opened to get well about the lacing end, the catch C³ is acted upon by a can
finger c, see Fig. 3 and 22, attachiod in suitable manner as by screws to the
slide 13 said cam finger serving to lift the spring catch and let the
spring Bat
as described to quickly close the jaws of the twisting device upon the lacing.
The jaws of the twisting device, see Fig 11, are suitably grooved at their
une faces to receive slide blocks d to which are suitably seemed the bunters d',
said slides having pin-like projections d' which enter cam slots in gunde-bais di
preferably dove-tailed in cross section and fitted to slide in dove tailed guide-ways
formed in the head B of the spindle, said gunde bais being joined at then inner
ends by a pin d' extended through and free to slide back and forth in a diametrical
slot du said spindle B, said pin d being connected to a rod d' located within the
centre of the spindle B, the iod having at its opposite end a second pin d³ sce
Fig. 3, extended outwardly though other longitudinal slots in said spindle and
entering a collar do suntounding said spindle loosely, said collar at tunes being
acted upon by a pusher pivoted at on the top plate, the outer end of said
pusher having a roller or other stud which enters a cam slot in a hub d fast on
the intermittingly rotating shaft d, said pusher being moved to slide said collat
on the spindle B towards the twisting-device just after the jaws of said twisting
device have been closed upon the lacing and the wire constituting the tip his been
thrust through the hole Bo and though said lacing, the collat by its movement in
the duection stated causing the bats d' caurying the benders d to be moved forward
to thrust said benders between the said jaws then holding the lacing with the tip-
wue through it, the bendeis acting upon said tip-we then normally straight and
forcing the same into the space between the jaws of the lacing clamp, bending said
wne into the position shown in Fig 17 and the wire having been bent, the collat dro
will be again acted upon by the pusher d" and be drawn back quickly in the
opposite direction to pull sard beuders from between the lacing clamp and back
into the normal position in the twisting device, so that the twisting operation can
take place, the spindle B being moved backwardly during the twisting of the
wne W to form the tip, said wie, during the twisting operation being held at its
cential or beut part by the clamp holding the lacing and as the wite is being
twisted into spal forni, to make the tip shown at the tight in Fig 19, the twisting-
device 16 1otated and is also drawn away from the lacing clamp and the ends of the
wire fually escape from the holes B¹º.
The wire to be used for the lauing tip will be taken from a suitable reel, not
shown, and thence be drawn through any usual we straightening device nut
necessary to be here shown, the straightened wne W being led to and through
a guide e, see Figs. 3 and 6, the latter figure showing the guido en uge 1.

page_text: The guide e is connected to and forms part of what I shall designate as the wire
feeding device, it consisting essentially of a carriage e' adapted to slide in a suitable
guide way e formed in a track e" held in place by bolts see Fig 3, said carttage
having a downwardly extended rim e³, see Fig. 4, which enters a slot in a feed
lever e pivoted at e* on the bed plate A.
The carriage has a clamp preferably serrated at its underside and supported
upon links, one of which is acted upon by a suitable sping which normally
serves to keep the clampe down upon the wire W, so that when the carriage is
moved in the direction shown by the arrow in Fig. 6 with the end of the wile
extended a short distance through the nose e and fitting rather closely the hole
therein, said end is thrust, as stated through the hole B in one of the jaws of the
twisting device, then through the lacing, then between said jaws, and through the
hole B in the other jaw, at which point the end of the wire is grasped by the wire
pulling device which I now will describe.
The wire pulling device, see Figs 3 and 5, consists essentially of a carriage
having a downwardly projecting post which enters a slot in an arm
pivoted
at on the bed A' said canlage being free to slide back and forth in the slot e
referred to in the guide bar.
The carriage has a stop pin which abuts against the free end of the we
thrust through the lacing by the wine-feeding device, and said wue is pushed well
under a dog pivoted at / on an upright portion of the carriage, said dog being
acted upon by a sping to ensure the hold of the dog on the wire.
The wire having been thrust under the dog to the stop aud caught by the dog,
the levers e and fare quickly moved in the opposite direction, causing both
carriages to be moved away from the twisting device, the dog then acted upon
by the spring holding on to the end of the wire and drawing the latter farther
through the lacing and the holes B, the clamp e of the feeding device, as the
carriage eis being moved backwardly, sliding freely over the wire yet held by the
dog f
As stated the dog f' engaging the end of the wire positively draws the samne
through the twisting device and the lacing until a sufficient portion of the wire has
been drawn through the lacing to form one-half of the tip at which tune the
carriage having arrived back into its normal position, the said dog meets an
opening device which turns the dog about its pivot to effect the release of
the we, which donc, the wue is severed near nose e' by a suitable wire cutting
device, shown enlarged in Fig. 7, the same consisting essentially of a slide bai
having at its outer end a stationary cutter g', said slide having also at its outer end
a suitable guide-way g' in which is free to slide up and down a carrier g' having a
cutter said carrier being connected to one end of a lever y pivoted at g' ou an
upright portion of sand slide
9.
The side-bat g is fitted to slide in suitable ways in a stand g the foot of which
is bolted to the top plate A³ said hai having a roller or other study which enters
A cam groove in cam go fast on shaft before referred to
The slide is thrust forward with the cutters separated to embrace the wire and
as soon as the cutters ac m position, the inner end of the lever is acted upon
and moved by a lug g" carried by and projecting from one side of the cam go and,
the wire having been cut off, the cam go acts to quickly retract the sand slide bar
into its normal position
The lever has its inner short end connected by an adjustable link h with a
lever mounted upon suitable stud 0, said lever having connected to it a pinion *
which is engaged by the teeth of a tack-but adapted to be slid in a suitable
guide-way attached to the bed A, see Fig. 4, said lack having a suitable roller
or other stud, which enters a cam groove at one side of a cam & fast on a short
shaft occupying a position somewhat below the shaft d, the shaft deuving
its motion from a geat h7 on the shaft d', which engages a gear on shaft h
The les et has its inner on short ai n connected with the lever by preferably
an adjustable link so that said levels ef and are during the reciprocation
20

page_text: of the ack caused to move first toward and then away hom each other
quickly
The shaft has fast upon it neat one end, a worm toothed geat, which
engages a worm-toothed gear 10 fast on a shaft A substantially at light angles to
the shaft, sand shaft beng mounted in suitable bearings, see Figs & aud 24,
ecmed to the intermediate plate A* hxed on suitable posts or studs erected on the
table A¹.
The shaft is provided with a disk 4", having at one side see Fig 20, a cim
groove 425, which receives a roller or other stud 426, see dotted lines Fig. 8,
projected from a lacing clamp actuator ", shown as a slide having a thi ce-aimed
head, each am being picvided with a sumable beveled face as " 17 saul
heveled faces acting at proper times upon the beveled lower ends of like bars 418,
there being two such bais, each adapted to slide up and down in suitable guido-
ways of a lacing-carrier, herein shown as an oscillating cattle, secured to the
upper end of a shaft 20 having hearings on the table and bed, the said shaft having
at it lower end, see Fig 9 a gear which is engaged by the teeth of a toothed
secter lever pivoted at " on the table A', the inner end of said sector-lever
having a suitable roller or other stud, which enters a cam-groove in a cam h" fast
on a shaft mounted in suitable bearings secured to the said table, said sector
lever oscillating said lacing-caire during the rotation of sand shaft, so as to
present one after another of its lacing-holding clamps "see Fig. 3 opposite the
twisting device in order that the lacing 1 protruding from the said clamp, may be
grasped by said twisting device
The oscillating carrier is provided in this instance of my invention with two
lacing clamps 7 so that when one or the other of said clamps is opposite the
twisting device to be there provided with a wire tip, the other of said clamps may
be opposite one of two like tip-cutting devices by which to cut off the end of a
completed tip and ensure uniforme length therefor
The tip-cutting devices are each composed essentially of a stationary blade m
see Fig. 1, 1 and 1º, attached to a stand m² supported upon the bed A, said blude
having co-operating with it a movable blade m, attached to a blade carrier m
adapted to slide in suitable guide-ways in said stand, said carer having jointed to
talk m, which is connected to one end of an elbow-lever m pivoted at m² on a
stand secured to table A', said blade-carner being normally depressed by a
spring me, the rear ends of the like levers m being acted upon at suitable tunes,
one by projection m on a beveled gear mo fast on the shaft h2, the other by a
projection attached to a disk m" also secured to said shaft.
The gent see Fig. 9 is engaged by a beveled gear m" on the shaft A' before
described.
The cam hub " on shaft has two like cam-wings which in the retation
of the said hub, strike a lever see Fig 8 and 24, pivoted at " and connected
to the clamp actuator " by a suitable pin m³, said levor m18 moving forward the
clamp actuator and imparting to it what I shall denominate as an auxiliary
thrust, the stud 426 of the clamp actuator being at that time duectly opposite
the open throat 425* of the groove in the cam but the thrust impaled to the
sand actuator is not far enough to entuely remove the stud 426 from said thiont
and consequently the said cam, as it continues its rotation, meets the said stud and
pulls the actuator back sufliciently to enable the main path of the cam to hereafter
control the movement of the actuator, the particula tune and object of these
movements being hereafter more fully desembed
The lacing clamps are both alike, so I need describe but one of them riz. the
one eferung to Figs. 25 and 26 and 20 to 32 inclusive
Each lacing clamp is composed of two jaws pivoted at n* upon the
cairier
One JAW of each lacing clamp has at its forward end a projection or lip n' seo
Fig 29, which serves to support the lacing at the proper level while the lacing
clamp is open.

page_text: The rear ends of the jaws receive between them the wedge-shaped upper end, sec
Fig. 33, which is an enlarged sectional detail m the hue y' Fig. 3, of a bar 4",
which is elevated, as before descubed, whenever the jaws are to be closed upon a
lacing, sail bats having attached to then upper ends in suitable manner a yoke
which as the ban 418 depressed acts upon the outer sides of the rearwardly extended
ends of said jaws, thus causing the clamp to be opened at the proper times not
only to permit the attendant to lay a lacing in position between the jaws, but also
to enable a lacing provided with a tip to be removed from the clamp
The particular ban 18 holding the lacing-clamp jaws opposite the twisting devia
is made to descend temporarily just after we has been inserted through the
holes B of the twisting device and the lacing and just before the commencement
of the twisting operation, to thus enable the bender, before descubed, to pass
between the opposed faces of the lacing clamp to put into the wie the preliminary
bend, indicated at W Fig. 17, the portion 427 of the outer wall of the groove 425
then acting on the stud 426 and the bender having been operated to put the
pielimmery bend Winto the wine and having been withdrawn from between the jaws
of the Jacing clamp, the part 428, of said cam groove, acts on the stud 426 to agam
quickly thrust the said clamp actunt forward, so that the cam 16 thereof again
acts upon the lower end of and litts the bar 418, then in line with it, to again effect
the film closing of the lacing clamp upon the lacing, preparatory to the operation
of the twisting-device
While one of the lacing clamps, for instance 4" Fig. 23 is opposite the twisting
device and holding the lacing and we to be made into a tip by the twisting device,
the other of said clamps, as for instance clamp 27 stands opposite one of the tip-
cutters, with the jaws of the clamp open, the lower end of the bat ¹³ co-operating
with the clamp being held down by a spung 430 and resting just beyond the
cam "
As soon as the clamp opposite a tip-cutter has been opened, said opening being
effected after the cutting off of the tip, the attendant will remove the fished lacing
and will lay in place of it, between the open clamp, the lacing next to be tipped,
and this clamp must be closed upon this fresh lacing preparatory to the movement
of the cater to place the lacing clamp opposite the twisting device
The preliminary movement given to the clamp actuator 4" by the level m¹ before
described is to enable the meline " referred to, to act upon and raise the bar of
the lacing clamp to thus close the said clamp upon the fresh lacing and cuable
sau clamp to carry the Incing with it as the cariier 1 is moved after the lacing
held by the cater has been tipped
While the canne 4 is moving to put the clamp h" opposite the twisting device,
the clamp actuator bar 4" occupies such a position with relation to the lower ends
of the bar that said bar rides over the arc shaped track 429 see Fig. 8 and the
bar co-operating with the clamp is kept elevated and the bai 1 co-operating
with the clamp is also kept elevated and the tip projecting from the clamp
has its outer end placed between the blades of the up-cutter and the latter is
inoved as described to cut off the outer end of the tip just about as the lower end
of the bax reaches and slides down the incline under the action of the
sping 430 thus opening the clamp" to enable the attendant to remove the finished
lacing and substitute for it a fresh lacing, and there atter, as before described, by a
movement of the clamp actuator the incline the cof is mado to raise the bar 18
to close the clamp /** upon the fresh lacing, and the clamp 4" loft opposite the
twisting device is temporarily opened, as before descubed, of the clamp, to
cuable the bunter to operate and bend the wne, after which the clamp is closed
upon the lacing having the preliminary bend in the wire preparatory to the rotation
of the twisting device to twist the wiem the form for the tip
From the foregoing description it will be readily seen how the lacing clamps are
brought one after the other into position to present a lacing to receive a wie to be
twisted into a tip and then to have its tip end cut off to uniform length
To accomodate for lacings of different thickness the bar
is made in two parts

page_text: connected together by a suitable screw in a slot in one part of the said bar, and
when aid screw is loosened the wedge-shaped top pait may be adjusted on the
lower part thereof by the adjusting screw o device xx and in this way the
normal position to which the bat may be clerated, may be changed so that
the wedge will enter more or less between the rear ends of the jaws and's close the
forward ends of the said Jaws more or less closely to properly grasp the lacing,
whatever its thickness.
The lower ends of the arms of the yoke * when the bar 18 is fully depressed
coter suitable notches see Fig. 33, in the carrier 19 said notches preventing possible
lateral twisting of the said yoke
Power to operate the machine may be derived from a belt n diven from any
suitable source and going to a suitablo pulley herein shown as of the friction
variety, loose on the power shaft n" alongside of a stable co-operating comical
member splined on said shaft and under the control of a suitablo shipper-
lever which may be operated when desired to stop the machine by or through a
suitable treadle ni
The power shaft n" has an attached pulley " which dives a belt n extended
over the clutch pulley part n loose on the shaft d and said power shaft also has,
as shown, a sprocket wheel r which by chain rotates the loose pulley part
The spindle B and the shaft are rotated intermittingly and at different periods
to effect the various operations herein alluded to at the desned relative times and
in the established ordet and to do this the louse clutch pulley parts and must
at times be permitted to run loose on their respective shafts and at other times be
connected operatively with said shafts, as I will now describe
The crank A has attached to it at its real side a disk n see Fig. 9, provided
with a tappet shown also by dotted lines Fig. 2, which acts once during cach
evolution of the shaft A' upon one end of an elbow-lever n pivoted at non a
suitable stand x, the upper end of the said lever, when moved by said tappet
striking a clutch controller n' pivoted at a³ and normally held by spring against
said level.
The upper end of the clutch controller is bent to form a finger, see Fig. 2B
which enters a slot in the periphery of the clutch member no fast on the shalt d
before referied to alongside of the continuously rotating pulley " loose on said
shaft and denying its motion from a belt herein before descubed, said finger,
when put into the slot referred to, by the spring standing in the path of move-
ment of the spring dog no, see Fig 2, and causing it to be disengaged from that
one of the lugs or teeth n" of the pulley with which it may be in engagement
and the pulley will thereafter run loose on the shaft until the finger of the
dog is drawn outwardly by movement of lever nas in Fig 2, thus letting the
fice end of the spring dog catch one of the stops n" of the driven pulley n
The pulley uns loose on the shaft (, so as to leave it at rest while the
spindle B carrying the twisting device is being moved forward, and, the spindle
having been moved forward until the twisting-device is in position to grasp the
lacing, the sand clutch controller n' is moved away from the said clutch disk, letting
the pulley n", then running loose, come into effective engagement with the disk n
and rotate the shaft d to effect the release of the clutch from the collar B" and
to then move the bender forward to put the preliminary bend into the wire as
described, and the bender having been thrust for ward and retracted by the lever d¹
the further rotation of the shaft d is stopped by freeing the pulley n¹² from said
shaft while the spindle B 18 being retracted and rotated to twist the wine and forin
a tip for the lacing.
The mam shaft A' has fast upon it one part of a clutch, the part being
loose as stated on the said shaft.
In practice the clutch part will carry a spring dog as described with relation
to the pulley 0 and the loose clutch pulley part will contain in practice a series
of stops as provided for with relation to the loose pulley "".

page_text: The part is also provided at one side with a projection - having in it a groove
to be described.
The clutch controller n' has extended therefrom at its lower end an arm n³x
see Fig. 1 and 9, provided with suitable bearings to receive a spring-actuated
bolt o.
One end of the said bolt is uorinally projected by its operating spring beyond the
inner end of said aim, so that when the said controller a is moved by the sping nº
to effect the release of the pulley n and leave the shalt dat rest, said bolt will
act against the upper end of the auxiliary clutch lever ol and will cause its lower
end having a finger, as already described with relation to the controller to retue
from the part of the clutch pulley parts on the shaft A' and permit the dog
cared thereby to engage, as described, a suntable projection on the continuously
running part 2, such coupling together of the parts causing the main shaft A+
to be rotated, to thereby effect the reciprocation of the rack bar A herembefore
described, the movement of which rotates the spindle B first in one and then in the
other direction for the proper number of rotations and at the same time causes the
Band shaft to be slid forward and backward ab alieady provided for
At each otation of the main shaft A during which time the rack A° 18
actuated, the projection alives opposite the end of a level of pivoted at o' and
tuins said lever so. that its upper end, see Fig 1, stukes a projection 310 extended
from the bolt o down to a slot in the arm nx and causes said bolt to be pushed
back, thereby oleasing the auxiliary clutch controller o' so that when the lever n³
is agam moved as described by the projection said bolt may pass the auxiliary
controller and not turn it upon its fulcrain
The shatt A has given to it one complete rotation while the shaft d¹³ is at rest
and vice-versa
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what

1. A machine for automatically putting on, twisting on, and finishing spiral-
like tapered wire tips or ends upon langs for shoes, corsets and such like, in
which machine the wire is taken in from a suitable reel by a wie feeding
device (e) which has a corresponding and dependent alteinating movement
with a wire pulling-device f-1', so that they simultaneously approach to meet each
other and recede to distance from each other, and which said 'wne-feeding device
puts the wire into holes of the jaws of a gupping and wire-twisting device B-Bie
the jaws of which open and close to grip the end of the lacing to be provided
with a tip, and then thrusts the wire though the lacmg, pulls it through to
suitable length and gets it cut off then by a shearing device g- and then baul
wne is glasped by the then just opened lacing clamp standing opposite and
being activated by the stroke of a pair of pushers in the twisting device B so
as to give a preparatory bend to said grasped wire, whereafter by a revolving
twisting and at the same time retrograding movement of the said wire twisting
device B, it is formed into a helical tapered tip at the end of the then, by the
Jaws of the lacing clamp still grasped lacing, and after which the twisting device
again advances and opens its jaws, and the lacing-clamps by rotation of its
carrier ¹, presents the still held and tipped lacing to a finishing device m', having
its place opposite this new position of the lacing clamp holding the said tipped
lacing, in order to get the tip finished by having its ends cut off to have exact
length and finished ends, during which operation another lacing clamp " on the
carrier is brought into oposition to the before mentioned twisting-device, to be
opened there automatically and to receive another length of lacing to get tlus
grasped and get a wire thinst through, and to begin the cycle so ngain.

page_text: 9) In a machine for automatically putting on, twisting on and finishing spiral-
like tapered wire-tips upon lacing ends as specified under 1), a device for
periodically rotating and stopping the shaft d" while the diving pulley n" on said
shaft is continually rotating, which said device consists of a tappet n' ou the rear
side of disk n upon crank disk A', sand tappet operating a clank-lever n³ which
when moved, shifts to the side a double-aimed lever held in contact with said
crank-lever by a spring, and thus pulls out of a slot in the periphery of the
clutch-disk 10 fixed on shaft d, the other end of said double-aimed lever n' and
thereby allows a spring dog otting on the inner side of the clutch disk n¹º to
engage into the lugs or stops of the driven pulley n¹ or not, and so to couple
lisco and rotate with it together shaft, or leave it at rest, Figs. 2, 2º, 2º, 2º, 3.

shaft, consisting (Figs. 1, 2 9) essentially of an arm nx, extending from the
clutch controlling lever and being provided with a spring-activated bolt o, pushed
outwardly, in order to shift an auxiliary clutch-controller o' consisting of a double-
armed lever like n' in Claim 9) which said lever acts like 10 and n' in Claim 9.)
to clutch or release the two clutch parts and and which said pait has a
projection with a groove which may strike against a lever of and so bring bolt o
out of reach of the coutroller lever O'.
