FRED TERSTEGEN, OF ELIZABETH, NEW JERSEY.

TIMEPIECE REPEATING IVIECHANISM.

SPECIFICATION forming part of Letters Patent No. 487,399, dated. December 6, 1892.

Application A,tiled April 5, 1890.

To @ZZ whom t may concern.-

Be it known that I, FRED TEESTEGEN, of Elizabeth, in the county of Union and State of New Jersey, have invented a new and useful Repeating Mechanism for Watches and other Timepieces, of which the following is a specification.

This invention relates to improvements in the construction of repeating mechanism for watches and other timepieces and to the arrangement of the said mechanism on the front plate of the watch under the dial, and also to setting the repeating mechanism to strike the time by means of a winding-pinion and a train of gearing operated b v said pinion.

In my application bearing even date herewith, Serial No. 346,780, I have shown and described a repeating mechanism in which the repeater-setting lever is set by suitable gearing connecting it with the winding-stein and arranged to break the connection between the repeater-motor and the stein-driven train by the action of. the winding-stem. In my present invention the repeater-setting lever is operated by the repeater mechanism automatically to disconnect the stem-driven train from the repeater-motor. Furthermore, in my presentinvention mechanism is described and shown whereby the repeating mechanism can be disconnected from the stem-driven train positively by a repeater-setting device provided with a inger which is adapted to be actuated by the finger of the operator.

My invention consists of a repeating mechanism so arranged that the same may be arranged to break the connection of the gearing between the winding-pinion and a repeatermotor for actuating the same when the repeating mechanism isset to astriking position.

My invention further consists ot' a system ofgearing for actuating a repeater-motor and connected with a winding-pinion which op erates a system of gearing for actuating the time-motor, said gearing for actuating the repeater-motor being breakable automatically or positively between the winding-pinion and the repeater-motor to prevent the repeating mechanism from being stopped inadvertently.

My invention also consists of a system ot' gearing for actuating a repeatermotor so arranged that the same is connectable auto matically or positively with the Winding-train Serial No. 346,781. (No model.)

that operates the gearing for actuating the time-motor.

My invention further consists ot' devices by which the connection of the said gearing for actuating a repeater-motor can be broken or by which the same can be connected with the winding-train that operates the gearing for actuating the time-motor.

My invention further consists in special gearing interposed between a repeater-motor and a winding-pinion and of mechanism for setting the stem-driven train into its handsetting position, b v which the motion of the winding-train is communicated to the dialwheels, said mechanism being also adapted to interrupt the communication between the winding-train and the dial-wheels when` the winding-train is in connection with said motor, and when the said mechanism is set so that the motion of the Winding-pinion is communicated to the dial-wheels said mechanism breaks the continuity of the said gearing between the winding-pinion and therepeatermotor.

My invention further consists in details of improvement and combination ot` parts that will be more fully hereinafter set forth.

In the accompanyingdrawings, Sheet I reprepresents my improved repeating mechanism and gearing torwinding the motorspring of the same connected with the winding-pinion ot' awatch and which is actuated thereby.

Fig. 6 represents a sectional view of the repeating-mechanism bridge and the plate A', showing the position of the striking-hammer and its construction and also illustrating the moderating-gear. Fig. 7 is a similar view IIO dicate corresponding parts.

A winding-stem D is connected suitably with a winding pinion or wheel l of a watch. The said pinion engages a crown-wheel 2, placed under a yoke Y, pivoted to the watchplate A and held in place by a cap and screws, as usual. At one end of the yoke is pivoted an intermediate winding-wheel 3, engaging the barrel-arbor wheel 4 when the yoke is in its Winding position.

5 is the intermediate setting-Wheel for transmitting the motion of the crown-wheel to the dial-wheels when the yoke is in its setting position.

6 is the minute-wheel, and 7 the cannonpinion placed on the center-post 8, suitable wheels being shown that connect the setting- Wheel 5 with the cannon-pinion 7, and which are called the dial-Wheels.

The above-described mechanism of a stem winding and setting Watch is of wellfknown construction and does not differ in operation from similar mechanism found rin other watches, exceptv as modified in the manner hereinafter described by the mechanism and modes of operation peculiar to my invention.

I will now describe in detail my novel devices for operating a repeating mechanism by means of a winding-pinion forming part of a stern-driven train of a watch. The winding pinion or wheel l engages a wheel 2, which engages a gear-Wheel 1l, which is pivoted in a suitable depression or seat in the watchplate A and held in place by a screw and forms here part of the stem-driven train. A gear-wheel U, engaging the wheel ll and turned thereby, is pivoted in a depression or seat in the watch-plate A and held in place by a hollow screw u2, as shown in detail in Fig. le. The wheel U is provided with a ratchet-tooth u', projecting from its upper side near its center hole. A shiftable Wheel V, having on its upper side a head or rim t4 and on its under side an arbor or staff T, is set upon the wheel U, and its arbor is placed in the hollow screw or stud u2, so as to shift up and down within the same. The wheel V is provided with a diagonal oblong hole or incut t, of which one edge on its under side is rounded off or beveled down and the other under edge of the hole t' is sharpened, and the said Wheel V rests upon the Wheel U in such a manner that the said ratchet-tooth u engages into the hole t of the wheel V and bears against its sharp edge, so as to form acoupling or clutch device whereby the wheel U can turn the wheel V. A suitable spring t2 presses by its free end upon the head t4 on the shiftable wheel V to keep one of the coupling devices engaged with the other coupling device. The wheel U is turned by the crown-Wheel 2 in either direction by the winding-pinion and stem-arbor. The arrangement of the parts is clutch device t of the wheel V.

such that when the crown-wheel is turned by the winding-pinion and stem to the right the shiftable wheel V is unlocked or d-isengaged from the wheel U and the motion of the stemdriven train is transmitted to the wheel 4, which Winds the motor-spring of the time mechanism; but by turning the winding-pinion by the stem-arbor to the left or reverse direction the motion of the same is transmitted by the wheel U to the wheel V by its clutch device u engaging and locking the The wheel V engages a wheel 12, pivoted to the plate A and in engagement with the wheel O, which engages the wheel N for actuating the motorspring of the repeating mechanism.

The clutch devices of the wheels U and V can be connected and disconnected by a setting device S', as will be described hereinafter, or by mechanism connected with the yokelever E, which is for the purpose of setting the stem-driven train in connection with the dial-wheels. The yoke Y, which is provided with a projection or arm y2 and beveled at its end, is moved by the said yoke-lever in contact with and under the head or rim t4 of the shiftable wheelk V. The said head t of the wheel V is arranged so that its top is larger in proportion to its bottom, so as to form a rim which is beveled or rounded off, and under the said beveled rim t4 the beveled arm y2 of the yoke operates.

The operation is as follows: The yoke-lever E being moved in the direction of the arrow,

IOO

its arm c comes in contact with the projection y of the yoke Y, which is turned thereby until the arm e of the yoke-lever is pressed against and onto the said projection of the yoke, as shown in dotted lines in Fig. l, and the said yoke is thereby moved to the position shown in dotted lines, in which position the Wheel 3 on the yoke is disconnected from the winding-wheel 4 of the time-motor and the Wheel 5 is connected with the dial-wheels, and the yoke, with its arm y2, is set under the beveled rim t4 of the shiftable wheel V', thereby lifting or moving the Wheel V out of connection with the clutch device of the Wheel U, as shown by the dotted lines in Fig. l and shown in Fig. lb. The stem-driven train can now be operated for setting the dial-wheels, and as the wheel V is disconnected from the stemdriven train the gearing of the repeater-motor cannot be. actuated and the dial-wheels may be set forward or backward without interfering with the repeating mechanism. By pushing the yoke-lever E back to its initial position the yoke Y is turned back to its Winding position by a suitable yoke-spring,

and the Wheel V, being released by the pro- I tached to the watch-plate, and which engages the wheelN', provided with a winding-arbor N for winding the motor-spring, placed in a seat arranged on the underside of the bridge b. The bridge b is fastened by suitable screws to the watch-plate A. Between the bridge l) and the said plate the moderating-gear or regulating-wheels are placed-viz., the wheel N', which is partly turned out on its upper side to forni a depression or seat for a motorspring M, as shown in detail in Fig. ld and Figs. 6 and 7. The said wheel gears with a pinion c, connected with a wheel N2. On the pinion c a ratchet-wheel is attached, engaged by a click controlled by a click-spring and fastened to wheel N2and operates in the usual manner, but not shown in the drawings, as it' is fully illustrated and described in my application for patent bearing even date herewith, Serial No. 346,780. The wheel N2 gears with a pinion attached to wheel N3, which in turn gears with a pinion attached to wheel Ni or escape-wheel with which the escapement N5 engages, as shown in dotted lines, Fig. l.

The mechanism for transmitting motion from the motor-spring to the racks and hamf mers consists of the wheel O, engaged by wheel N'. The said wheel() is provided with a catch p', bearing against the edge of the hour-striking rack P, placed above or on the wheel O and is moved by the same. The wheel is provided with an opening o3, giving place for the seconds-hand statt, which passes through the same. The hour-rack P is provided with a pin or shoulder p2 near its center, projecting downwardly through an opening o4, provided for it in the wheel O, and the rack P through the said pin is engaged by the rack-spring NV, placed under the wheel O. This rack-spring is for the purpose of setting the hour-rack with its snail-piece p4 against the snail Z. A rack Q is placed above or on the hour-rack P and moved by the catch q', attached to the rack P, as shown. The rack Q is provided with a shoulder q2 near its center, engaged by the rack-spring X, which serves for holding the racks and wheel O down in place against the watch-plate A', and is also for the purpose of setting the rack Q with its snail-piece Q4 against the snail K. The snail K is attached. to the cannon-pinion 7, placed on the center post 8, forming part ot' the time-train of the watch. In connection with the snail K the arm 702 of'the surprise 7c at the full hour turns one tooth ot' the starwheel Z' forward. On the star-wheel the jumper J acts by its springj' as usual in repeaters.

The hour-rack P is provided with an incut p3, which forms a seat for the releasing' device R, pivoted at r to the watch-plate and under the bridge b. A pin b', attached to the bridge l) and having its end or point beveled down, projects toward the releasing device R. The releasing device is formed as aiiat spring, which is provided with a pin or suitable finger s', forming a stop-finger which projects downwardly from the releasing device and in line with a projection or guide device o2 ofthe wheel O. The said guide device o2 is for the purpose of setting and pressing the releasing device R by its stop-finger s' against and upon or over the pin b' on the bridge Z2, thereby bending or lifting' the end of the releasing device out of and away from the incutpof the rack P to release the strikingracks and also for the purpose of stopping the winding otm the stem driven train, so that the repeatermotor spring cannot be overwound or broken.

A device S', which I will call the setting device, is pivoted to the watch-plate at a2 and isin connection with a spring S5, attached to the plate at t3. The setting device S' is provided with two projections or arms. The longest arm 'Si is engaged by the strikingrack Q, which holds the short beveled arm s of the setting device S'away from the bev eled rim t4 ofthe shiftable wheel V', as shown in Fig. l, when the repeating mechanism is in its normal or initial position. The said beveled arm s of the `setting device S' is intended to be moved against and under the beveled rim t of the shiftable wheel V' for setting the same out of connection with the clutch device of the wheel U.

The operation is as follows: When the winding-stem D turns the winding-pinion 1, crown-wheel 2, wheel ll, wheel U, engaging by its clutch device the wheel V", wheel 12,`

and wheel O, engaging the motor-wheel N', the said wheel Nis turned in the direction of the arrow shown on bridge b in Fig. l until the projection or guide device o2 of the wheel O comes in contact with the pin or stop-finger s' of the releasing device R, thereby turning and pressing the releasing device against and upon or over the pin b' against the bridge b and also stopping the further windingof the stem-driven train and setting or bending the releasing device `R out of engagement with the rack P. The rack P, being set free, is turned by its spring W' against the hounsnail Z and the rack Q by its spring X against the snail K or into their striking position. The arm 57 of the setting device S' being set free by the repeating mechanism and the rack Q being released, the setting device S is moved by its spring 35, and its beveled arm s is set under the beveled rim t4 ot' the shiftable wheel V', thereby moving the said wheel V and shifting it out of connection with the ratchet-tooth u of the wheel U, as shown by the dotted lines in Fig. l and shown in Fig. l, thereby automatically' disconnecting the wheel V from the stein-driven train. The motor spring moves the wheel N', engaging the moderating gear, and now moves back the wheel O, and its catch p' comes in contact with tho rack P, turning the same back, and its rack-teeth, engagin g the ham mer-tooth 1-2,0perates the hammer H, which by its spring F is forced against the gong-spring G. The hour-rack P on its return motion by means of its catch q' comes again.

in contact with the rack Q and, turning the same back, its rack-teeth engaging the hammer-tooth 2, operates the hammer I, which by its spring f2 is forced against the gong-spring G', and when the last stroke is made the rack Q by the edge g3 comes in contact with the releasing device R, resting upon the pin b' on the bridge b, and turns and pushes the ref leasing device backward and from the said pin, whereby the releasing device springs back into the incut or seat p3 of the rack P At the sarne time the end or edge Q6 of the rack Q cornes in Contact with the arm S7 of the setting device S' and turns the same back, whereby its beveled arm s6 is moved 4away from under the beveled rim t* of the shiftable wheel V in the position as shown in Fig. 1, and the shiftable wheel is pressed back again in contact with the ratchet-tooth u of wheel U by the spring t", (as shown in Fig. 1%) thereby automatically connecting the gearing of the repeater-motor spring with the Stern-driven train.

The hammers are operated by their hammer-teeth as usual in repeaters. The hammers are shown pivoted to the front of plate A', and the head of each hammer is suitably formed s as to project through a suitable opening a3, provided for it in the front plate in position to strike the gong-spring on the other or under side of the front plate A', to which the -is placed on a post or stud a4, attached to the watch-plate. A suitable spring Z', attached to the watch-plate at 153, as shown in Fig. 2, presses against the under side of the said wheel V. Above the wheel V' is an arm of vthe yoke Y, provided with a projection y2 and a projection @/3, divided by an incut or hole y, as shown. The projection ys of the yoke bears on the hub Z of the shiftable wheel V and is in line with the said hub when the yoke and stem-driven train are in the winding position for t-he time-motor spring, as shown in Fig. 2, and the wheel V' is pressed oi` set out of connection with the wheel 12 and wheel 11, and therefore the gearing of the repeatermotor spring is disconnected from the stern-driven train, as shown in Fig. 2*. The position of the yoke Y is changed by an arm of the yoke-lever E, which arm is provided with two steps e2 and e', coming in contact with the projection y' of the yoke Y to give two different positions tothe same. When the yoke-lever E is turned to the position shown by the dotted lines in Fig. 2, the step c2 is set or pressed onto the projection 'y' of the yoke Y, which is moved thereby to the position shown in dotted lines, in which position the wheel 3 on the yoke is disconnected from the winding-wheel 4 of the time-motor and the yoke, with its projectionv if, is set out of line with the hub Z of the shiftable wheel V' and the incut g4 of the yoke is brought in linethehub of the said wheel, which is pressed and set into the said inout g4 by its spring Z', and thereby in connection with the wheel 11 and wheel l2, as shown in Fig. 2a, and therefore the gearing of the repeater-motor is connected with the stem-driven train. When the yoke-lever E is turned so that its other step e' is pressed against and onto the projection y' of the yoke, the projection y2 of the same cornes in contact and in line with the hub Z ot' the wheel V', which is thereby pressed or set out of connection with the wheels l2 and 11, and the wheel V is in the same position again as in Fig. 2b, and therefore the gearing of the repeater-motor is disconnected from the stem-driven train, as the yoke is now in its hand-setting position and the stem-driven train in connection with the dialwheels for setting the same. When the yoke-lever E is pressed back, the yoke Y is set by a suitable yoke-spring to its winding position and the stem-driven train in gear with the winding-wheel i of the timemotor, as usual. The projection @/3 is then resting on top of the shiftable wheel V to disconnect the said wheel from the

wheels

12 and 11, and istherefore out of connection with the gearing of the repeater-motor, and the stein-driven train can be turned iny either direction. When it is desired to make the repeater strike, the yoke-lever E is turned, as before described,so that its step e2 is pressed onto the projection 'y' of the yoke Y, thereby moving the yoke with its incut 1/4 in line with the hub Zot the shiftable wheelV,which is set by itsspring Z' in gear with the wheels 11 and l2, and the stein-driven train is thereby connected with the gearing of the repeater-fnotor, which is actuated thereby.

A setting device S', controlled by its spring si', is used to disconnect the wheel V from the stern-driven train when the striking-rack Q is being released, as described in connection with Fig. 1, Sheet l. The short arm s6 of the setting device S' is then pressed against and upon the hub Z, as shown in dotted lines in Fig. 2, Sheet Il, and the wheel V is thereby pressed out of connection with the

wheels

12 and 11 and is disconnected from the sterndriven train, as shown in Fig. 2b. When the striking-rack is turned back to its initial position by its motor, it comes in contact with the long arm s7of the setting device S', which is turned thereby and turns its short arm S6 away and out of engagement with the hub Z on the shiftable wheel V', which is set by its spring Z' again in connection with the wheels 1l. and 12, thereby again connecting the stemdriven train with the gearing of the repeatermotor, as shown in Fig. 2f. In case the set- IOO tingdevice S is not used, when the repeatermotor is wound and the striking-rack released the winding-gear of the repeater-mo tor remains in connection with the stemdriven train until the yoke-lever E is turned, whereby the yoke Y changes its position, so that either one of the projections y2 or g3 is moved upon the hub Z of the shiftable wheel V', thereby pressing the same out of connection with the stein-driven train, as before described. The yoke-lever E, with its step e2, is for the purpose of permitting the gearing of a repeater-motor to be put in connection with the stem-driven train of a watch.

In Fig.3 the stem-driven train and its winding and hand-setting arrangement are of wellknown construction, and my invention is shown applied thereto. The wheel O, wheels l2 and ll, and the shift-able wheel V', with its hub Z, controlled by its spring Z', are the same as described in Fig. 2. The shiftable wheel V' is set in connection with the stem-driven train by the setting device S', provided with an arm S8, which is to be engaged with and actuated by a finger of the operator. The setting device S has its long arm s?, which comesin contact with the stri king-1ack,forined as a thin latspri1'1g,as shown in Fig. 3, which is set by the spring S5 on the top of the rack ,and its other arm s rests upon the hublot Wheel V to disengage the same from the wheel l2, as shown in Fig. 3 and in dotted lines, Fig. 32

To actuate the repeater-motor and operate the repeating mechanism to strike, the setting-lever S' by its arm .98 is turned in the direction of the arrow by the linger of the operator until the spring-arm s7 of the said lever snaps behind the striking-rack Q and holds the setting-leverS in this position, as shown in the dotted lines in Fig. and in full lines in Fig. 3, whereby its arm s6 is moved away and out of line with the hub Z of the shittable wheel V', which is set by its spring Z in gear with wheel 12, which latter gears in wheel O, and the wheel O is in connection with a winding-gear of a repeater-motor, as before described. When the repeater-motor is being actuated by the stein-driven train and the striking-rack Q is released, the setting-lever S is released and is turned back again by the spring S5 to its first or initial position and the arm s is pressed against and upon the hub ZA of the shiftable wheel V', which is thereby pressed and set out of connection with the wheel 12,and the gearing of the repeater-motor is therefore out of connection with the stemdriven train. The stri king-iacl Q is provided on its end edge with an inclined notch or beveled groove rj', and when moved back to its initial position by suitable means actuated by the repeater-n1otor the said beveled groove Q7 comes in line with the point or end of the spring-arm 57 of the setting-lever S', and the said spring-arm S7 is thereby bent on and over the rack Q, as shown in Fig. 3 and in dotted lines in Fig. 3% but when the settinglever S' is turned by the finger of the operator, as before described, its spring-arm S7 is turned away from the upper side of the rack Q and snaps behind the said rack and with its end or point rests against the fiat edge and behind the beveled groove Q7 011 the rack Q, as shown, and in this position ot` the said setting-lever the connection is effected by the gearing of the repeater-motor with the stemdriven train; but when the rack is released at its striking position then the said gearing is automatically disconnected from the stemdriven train, as before described. In this figure the device for setting the hands is entirely separate from the gearing of the repeater-motor and is of well-known construction, as before stated.

Fig. 4 represents a stem-driven train of well-known construction to which my invention is applied. The shiftable wheel V' is attach ed to a sliding arbor T, (shown in Fig. 4%) which passes through the watch-platesA' and A and on its opposite end is provided with a gear-wheel V, which engages the wheel N for actuating a motor-spring, as described and shown in my application for patent bearing even date herewith, Serial No. 346,780.

The shiftable wheel V', placed on one side ot' the crown-wheel 2 and out of gear with the same, is set in connection with the said wheel by the setting device S in the following manner: The setting-lever S is provided with an arm 58, similar to that described in Fig. 3, and with an arm s, beveled down on its upper side, as shown. The said setting-lever t" is moved in the direction of the dotted lines by the finger of the operator until its arm s is moved away from under the shiftablc wheel V', which is then pressed by its spring t2 in gear with the wheel 2, as shown in the dotted lines in Fig. 4 and in solid lines in Fig. el, and the wheel 2 is thereby connected with the gearing of a repeater-motor, and the arm s6of the setting device S is locked by bearing against the edge of the wheel V', as shown. The gearing of the repeater-motor can be disconnected from the said train either by pressing or pushing with the finger the setting-lever S inwardly or back again to its initial position, by which operation the part sG is pressed under the sbit'table wheel V', which is thereby pressed out of engagement with the wheel 2, as shown in dotted lines in Fig. 4 and in solid lines in Fig. 4, or the said whcelV',with

its sliding arbor T, can be operated by a spe` cial setting' device S, which operates entirely independent ofthe setting device S', as shown in Fig. 4, whereby the sliding arbor is shifted and its wheel V disengaged from the wheel 2 by unlocking the setting-lever S', which is pressed under the Wheel V' by a spring S5, provided for the same and shown in Fig. 4.

The operation of the special setting device S is fully described and shown in my application forpatent bearing even date herewith, Serial No. 346,780. The device forsetting the hands is entirely separate from the gearing IOC IIC

of the repeater-motor and is of well-known construction.

Fig. 5 represents a stein-driven train ot' well-known construct-ion not forming part ot' this invention, but connected with it or that part of the invention that relates to interrupting the connection between the windingpinion and the gearing of the repeater-motor. The gearing for the repeater-motor is provided with a locking or clutch device, as described and shown in my application for patent bearing even date herewith, Serial No.

346,780. The said gearing is disconnected from the stem-driven train through the mechanism connected with the yoke-lever E for adjusting the stem-driven train to its handsetting position and is illustrated in Fig. 5a. The yoke-lever E is provided with a pin e5, which comes in contact with a setting-'piece e4, pivoted to the watch-plate and provided with an arm e', which'engages the projection y of the yoke Y and turns the same in the usual manner when the yohe-leverEis drawn out to its setting position. The said parts are old and their operation is well understood. The novel features are illustrated in Figs. 5, 5a, and 51 and will now be described. The setting-piece e4 is provided with a beveled stud e3, which operates a spring-bar t9 forA shifting the clutch or locking device of the gearing of the repeater-motor and disconnecting the same from the stem-driven train. The spring-bar t9 is provided with a hole t7 and a groove t8 and has a projection 156, as shown in detail in Fig. 5b, and through the said hole the arbor T and its clutch device are placed, and its collar t5 tits into the said groove of the spring-bar, and the said arbor is set and shifted by the said spring-bar when the beveled stud e3 is placed against and under the projection t of the said spring-bar, which is thereby bent upward, so that the clutch device t of the arborTwill be disconnected from the clutch devicett of the wheel U, and thereby disconnect the gearing ofthe repeater-motor from the winding-train, as s'hown in dotted lines in Fig. and the said beveled stud e3 is set and placed against and under the projection t6 of the said spring-bar t9, when the yoke-lever E is drawn out to its setting position. By pushing the yoke-lever E backthe setting-piece e4 is returned to its initial position by a suitable spring m2 and sets the beveled stud e3 away and out of engagement with the projection t6 of the said spring-bar, so that the same snaps back and the arbor, with its clutch device t', is connected again with the clutch device u of the wheel U by the pressure of the spring 252, whereby the gearing for the repeater-motor is set in connection with the winding-train, as shown in Fig. 5. Thus it will be seen that the connection of the gearing for transmitting its motion to a motor-spring of a repeating mechanism from a winding-pinion can be arranged to be broken in various ways and that the connecting of the same can be done automatically and separately; also, that the disconnecting of theV same can be done automatically by a repeating mechanism or by a yokelever E or by a setting device actuated by the finger ot the operator.

The connection ot' the gearing for transmitting the motion to the motor-spring of a repeating mechanism from the winding-pinion can also be arranged to be broken at any suitable point, or one or more wheels may connect with or-disconnect from each other, or other suitable coupling devices may be used or other suitable clutch devices, as may be desired. The main object of the said coupling or shiftable gearing is to furnish means by which the motion from a winding-pinion can be transmitted to a motor-spring of a repeating mechanism and that the connection of the gearing between a winding pinion and the said motor-spring can be broken.

The invention further consists of means whereby the gearing between lthe windingpinion and the motor-spring ot a repeating mechanism can be connected and the said connecting of the gearing can be actuated, first, automatically by the repeating mechanism provided with a setting device S by its part .S7 moving the part s6, as in Fig. l, Sheet I, and Fig. 2, Sheet II, and also in Fig. 5,by the setting device S, fully shown and described in my application for patent bearing even date herewith, Serial No. 346,780; second,A by a yoke-lever E to be set by the operator, as in Fig. 2, Sheet ILby its step c2 moving the part ff, which produces the same result as the parts SS and e6 ot" a setting device S', as in the following tigures; third, by the setting device S to be set by the operator as in Figs. 3 and 4, Sheet II, by its part S8 moving the part S6.

The disconnecting of the gearing can be done, first, automatically by the' repeating mechanism provided with a setting device S by its part S7 moving the part s6, as in Fig. l, Sheet I, Figs. 2 and 3, Sheet II, and in Fig. 5, by a setting device S, fully shown and described in my application for patent bearing even date herewith, Serial No. 346,780; second, by a yoke-lever E to be set back by the operator by its part c2 moving the part g3, as in Fig. 2, Sheet II, which produces the same result as the parts ss and 86 of a setting device S; third, by a setting device S to be set back by the operator by its part S8 moving the part s6, but can also be arranged to be disconnected automatically by using a setting device S, as shown in Fig. 4, Sheet Il, which operates separately from the setting device S, as described. The disconnecting of the said gearing is also produced by suitable mechanism connected with a yoke-lever when the same is moved to set the stem-driven train to its hand-setting position, as shown in Figs. l and 1b, Sheet l, and described in Figs. 2 and 5, Sheet II.
