UNITED STATES PATENT OFFICEQ HENNING HAMMARLUND, OF CHICAGO, ILLINOIS,

WATCH.

SPECIFICATION forming part of Letters Patent No. 388,036, dated August 21, 1888 Application filed March 17, 1887. Serial No. 231,251. (No model.)

.To all whom it may concern.-

Be it known that I, HENNTNG HAMMARLUND, a subject of the King of Sweden, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Watches, of which the following is a specification.

The more prominent features of my invention relate, first, to a novel mode ofA winding up a watch, whereby in place of turning the mainspring-arbor by a key, according to the old way, or of winding up the mainspring aecording to the more modern stem-winding system, the operator can by a single pull upon a button wind up the mainspring, which button is then returned to its normal position, desirably at the point heretofore occupied by the rotary stem-winding button on the pendant. To the attainment of such end I provide a flexible strip, which is normally coiled around the mainspring-barrel and provided at its outer end with the pull-button, which will be held in its back position, desirably on the pendant, at such time as the strip isin its coiled condition. By drawing this button outwardly and away from the watch the dexible strip can be uncoiled in a manner to rotateV the barrel, and consequently to wind up the mainspring. After the liexible strip has been drawn out to an extent to wind up the mainspring it is restored to its norrnally-coiled condition within the watch, dcsirably by spring-power, which said power is desirably attained by forming the flexible winding-strip of spring metal, so that said strip shall combine with the feature of flexibility suitable to permit it to be wound or coiled upon and unwound or uncoiled from the barrel the feature of sufhcient inherent elasticity to automatically restore it to its normally coiled or wound condition after it has been drawn out and released.

The principal objects of the foregoing are: the attainment of ease and rapidity in winding; the absence of all wheels in the winding mechanism, (heretofore from five to eight wheels have usually been employed) and hence the avoidance of the breakage and wearing out of gearing heretofore incident to winding mechanisms; the avoidance of any necessity for or liability of disturbing the regular running of the watch by rocking or vibrating it during the operation of winding up the mainspring;

the avoidance of what is termed the back stroke of the click-spring and mainspring, heretofore consequent upon each winding impulse, and not only weakening the same, but frequently causing the breaking of the mainspring; the attainment of the winding up of the mainspring by a steady pull, and other minor advantages which will be apparent to those skilled in the art `to which this invention relates.

The second feature of my invention relates to means whereby during the winding up of the mainspring a winding indicator-hand upon the dial-face can be turned from the rotation of the mainspring-barrel through the medium of an uptrain of gearing, and whereby during the running down of the mainspring the said indicator-hand can be turned from the mainspring-arbor through the medium of a downtrain of gearing. To the attainment of such ends Iprovide a rocker with an uptrain, which is driven from the barrel during the ro tation of the barrel in a direction to wind up the mainspring, and a downtrain, which is driven from the mainspring-arbor, the rocker being shifted to place the uptrain into connection with the spindle of the winding indicatorhand during the winding up of the mainspring, and subsequently shifted to place the downtrain in connection with the spindle of the winding indicator-hand and free the uptrain from connection therewith as soon as the winding-up action ceases.

The third feature relates to means whereby during the free running down of the main spring it shall serve, in addition to its usual function, to maintain the downtrain of gearing in position to turn the indicator-hand, while, on the other hand, during the winding up of the mainspring the downtrain shall bc automatically placed out of position for controlling the indicator-hand, and the uptrain automatically and simultaneously therewith placed in position to control said indicatorhand during the entire operation of winding up the mainspring. To the attainment of such ends the rocker carrying the up and down trains of gearing is,by the action ofthe mainspring, shifted to normally place the downtrain in connection with the spindle ofthe winding indicator-hand, while on the other hand,the barrel is turned to wind up the mainspring,during which winding aetion the force of the mainspring normally exerted against the rocker is counteraeted and a spring to which the rocker is subject permitted to shift the rocker in a direction to place the uptrain in engagement with the spindle of the winding indicator-hand.

Among the principal obj eels of the two last-` mentioned features are to cause the winding indicator-hand to move continuously and steadily during the unwinding or running down of the mainspring and to effect a like movement in a reverse direction on the part of the Winding indicator-hand during the winding up of the mainspring, thereby indicating the condition of the mainspring with greater certainty and nicety than can be attained by causing the winding indicator-hand to move intermittingly or with a succession of impulses; and, further, to avoid the presence of springs for controlling the movement of the winding indicator-hand and to operate it from gearing having regular depths.

A fourth feature relates to novel and improved means for permitting the regulation of the watch without opening the back cap, the principal objects being to avoid the exposure of the works in regulating the watch, to facilitate the regulation thereof, and to permit the regulation to be effected with ease and precision.

A fifth feature relates to novel and improved means for setting the hands; also, to an improved construction of arbor for the center pinion, the objects being simplicity of construction and arrangement, the absence of idle-wheels from the motion-work and a free action thereof except at the operation of setting the hands, the attainment of a desirable spring frictional contact of the arbor with the center pinion, and the attainment of other useful ends which will be apparent to the skilled watch-maken,

Further features consists in certain details, all as hereinafter more particularly set forth.

In the drawings, Figure 1 represents a plan view of one side of the under or dial plate, which carries the watch mechanism and which isto be fitted within the center" of the watchcase, the side vof said plate represented in this figure being the one whereon the bridge-plate B is arranged. This figure also represents in dotted lines a portion of the outline of the watch-case and pendant. The remaining gures are on a larger scale than Fig. 1 and are as follows: Fig. 2 represents theopposite side of the dial or under plate, A, of Fig. 1, the Winding-button F shown in said Fig. 1 being omitted, and the outer end of the hand-setting stem broken away for convenience of illustration. Fig. 3 is au enlarged detail representing a portion of the dial or under plate, A, and is mainly designed to represent the regu lating devices. Fig. 4 is a sectional detail taken through Fig. 3 on the line :c x, and mainly represents in section the rotary disk for actuating the regulating-arm. Fig. 4** is a detail showing a portion of the back cap, I, of a watch-case, with one of the hubs of the regulatingdisk exposed through an opening in the back cap. Fig. 5 is aface view mainly of a portion of the dial, this view serving to show the winding indicator-hand. Fig. 6 represents a section on the line y y, Fig. 2. Fig. 7 is an enlarged view of the arbor for the usual center pinion. Fig. 8 represents one side of the dial or under plate, A, with the bridgeplate B and the usual works removed. It illustrates the winding-strip slackened and partly wound in the groove surrounding the mainspring-barrel. Fig. 9 represents a seetion through a portion of plate A, Fig. 8, on the line z z. Fig. 10 represents a section through the pendant and the pull-button for winding up the watch. Fig. 11is a detail representing, in elevation, a portion of the devices of Fig. 9, a small part only of plate A being shown in section. Fig. 12 is a detail section on the line z z', Fig. 1. Fig. 13 represents in elevation the perimeter of the barrel. Fig. 14 represents a section taken through the barrel on a plane at right angles to its axis of rotation, and includes the click-spring 2. Fig. 1'5 is a detail section on line z2 z2, Fig. 3. Fig. 16 is a plan view of a portion of the under side of the bridge or bearing piece 41 shown in Fig. 15. Fig. 17 shows the inner or pivotal end portion of the regulator-arm 31. Fig. 18 is an enlarged sectional detail through a portion of the barrel, this view serving to show, in section, a portion of the line of ratchetteeth 4 of the barrel and the inner catch end of the winding strip or spring,a portion of the line of ratchet-teeth 15 for the click-spring beingincluded in this figure. Fig. 19 is a detail showing in section a portion of the lid or front cap of a hunting-case watch and in elevation the outer endof thehand-setting stem.

In said drawings, A indicates the under or dial plate, which carries the watch mechanism and which is to be fitted within the ceuter of the watch-case, as usual. This plate A is provided at one side with the upper or bridge plate, B, and at its opposite side is to be covered by the usual dial, C, it being understood that the upper or bridge plate, B, will be covered by the back cap, as is customary in watches.

The niainspring D is arranged within the barrel E, Fig. 6, and around the arbor 1,which latter has one of its bearings inthe bridge plate B and its opposite bearing in the barrel, the inner end of the mainspring being attached to said arbor aud its outer being attached to the barrel, as usual. p

As a means for turning the barrel in order to Wind up the mainspring, I provide the winding-spring F, arranged to normally lie in a coil around the barrel with its inner end in engagement with the barrel and its outer end extending tangentially to the barrel and attached to a pull-button, 6, which is to be drawn or pulled out from the pendant, so as .to temporarily uncoil the windingspring F,

and in so doing turn the barrel. After the pull-button has been pulled out and away from the watch to an extent to draw outasufticient length ofthe winding-spring F, the pull-button can be released by the operator, whereupon the winding-spring, which has the same normal bow as the barrel,will instantly spring back into its original coiled condition around the barrel. This reeoiling of the windingspring F around the barrel will take place notwithstanding the fact that the barrel is held against back rotation bythe spring-pawl or click-spring 2, Fig. I4, such reeoiling on the part of the winding-spring F being permitted by causing its inner end to engage the barrel through the medium of a hook or beveled catch, 3, Fig. IS, secured to the inner end of the winding-spring F and arranged to engage in a line of ratchet-teeth, 4, with which the barrel is provided alongits perimeter. These teeth 4 upon the barrel and the bevel of the hoek or catch 3 on the inner end of the winding-spring are arranged so that when the winding-spring is drawn out from the watchcase the catch will positively engage the said teeth on the barrel, and thereby cause the barrel to be turned to an extent proportional to the extent to which the winding-spring is drawn out from the case; but, on the other hand, after the winding spring has been thus drawn out and then released, the bevel side ofthe catch 3 will ride back over the teeth 4 of the barrel, thereby permitting the retractile energy ol' the winding-spring to bring said spring again into a coiled condition around the barrel. As shown in Figs. l and 8, the outer end portion of the winding-spring lies in and is guided by a channel, 5, which is formed in the plate A and arranged tangential to the barrel.

The pull-button 6, by which the windingspring can be drawn out for the purpose of winding up the mainspring, is desirably connected with the winding-spring by a swiveljointto preventaecidental twisting ofthe winding-spring. To such end the outer terminal ot' the winding-spring is secured to a stempiece, 7, Fig. l0, and the pull-button 6 swiveled to such stem-piece in any suitable wayas, for example, the button may have a contracted inner end portion of its shank extending through an opening in the outer end of the stem-piece 7 and engaging a nut, 8, which is arranged to turn within a socket or recess in the stem-piece. In such case the stem-piece can have an opening for the admission of said nut. When the winding-spring is in its normally-coiled condition upon the barrel, the stein-piece 7 and also the main or larger shank portion of the button will lie within the hollow pendant 9. (Indicated in dotted lines in Fig.

I and in full lines in Fig. l0.) Hence, should anyone turn the button, mistaking the watch for a stem-Winder, no harm will be done tothe winding-spring, since they button will be free to turn independently ol the said spring.

The devices forindicating the extent to which the mainspring is wound up and for indicating at all times the condition of the mainspring, so as to show whether or net it has run down or to what extent it has run down, are as follows:

Upon the face of the watch-dial is arranged an index-hand or pointer, G, Fig. 5, which is used in conjunction with -an index, 10, consisting of a circular row of numbers. vThe pointing of the oscillatory index-hand G relates to the numerals, serving, ofcourse, to indieate the different conditions of the mainspring. This indeX-hand is turned in one direction from the rotation of the barrel during the operation of winding up the mainspring, while, on the other hand, during the running ofthe watch mechanism said hand G is turned in a reverse direction through the medium of certain connections with the arbor l, to which the mainspring is attached. To the attainment of such ends I provide upon the dial side of the plate A a rocker, H, carrying two separate sets or trains of gearing, one train, which I term the uptrain,77 being driven from the barrel, and the other, which I terni the downtrain,77 being driven from the arbor l, to which theinner end ofthe mainspring is attached,the said rocker being arranged whereby it can be turned first one way to connect the uptrain with a gear-wheel, Il, on the spindle 12 of the winding indicator-hand G, and then turned in an opposite direction to throw the downtrain into gear with the said gear Il on the spindle of the indicator-hand.

The rocker II (see Figs. 2, G, and I2) consisls of a plate let into a recess, 13, that is formed in the dial side of plate A. The plate forming the rocker is ot' a proximately segmental shape, and,while the recess is of a corresponding eontour, it. is lnadc somewhat larger than the rocker, as best shown in Fig. 2, in order to permit the desired extent of oscillation on the part ot' the rocker. The rocker is tted to oscillate about the barrel E, to which end the barrel has at one end a eylindrie hub portion, 14, Fig. I8,whieh is received in arecess formed in the inner side ot' the rockerplate H, and partially indicated in Fig. 6. In this connection it maybe observed that the spring-pawl or click-spring 2,which engages a ratchet, I5, on the barrel E, as in Fig. 14, is attached to the inner side ol" the rocker I-I, as indicated by dotted lines in Fig. 2, and that the barrel has between its said ratchet 15 and its ratchet 4, hereinbefore described, a smooth cylindric portion, I6, Fig. 13, which has a bearing in the plate A, as will be understood from Fig. 6.

rIhe uptrain, whereby the winding indicatorhand G is turned in a direction to denote the winding up of the inainspring, comprises a ring-gear, I7, Fig. 2, which is rigidly secured to one end oi' the barrel E and arranged to engage a gear, 1S, which is mounted upon the rocker H, the piece I9, herein shown secured tothe rocker, being p .aetically a portion ofthe same and affording one of the bearings for IOO 4 saaose the spindle of the gear-wheel 18. The spindle of the gear 18 or the gear itself is provided with a small cog or pinion, 20, (shown in dotted lines in Fig. 2 back of or under the gear 18 and in full lines, Fig. 12,) which said pinion is designed to engage the gear 11 on the spindle 12 of the winding indicator-hand G when the rocker is in position for such purpose.

The downtrain comprises a gear-wheel, 21, which is fixed on the squared end of the arbor 1, to which the inner end of the mainspring is attached, the said gear-wheel 21 being in engagement with a gear-wheel, 22, and the said gear-wheel 22 in engagement with a gear-wheel, 23, as illustrated in Fig. 2.

The gear-wheel 23 or its spindle is provided and rigid with a pinion, 24, which is at the inner side of the gear-Wheel 23, as indicated in dotted lines, Fig. 2, and shown in full lines in Fig. 12. The pinion 24 of this downtrain is to engage the gear-wheel 11 on the winding indicator-hand spindle alternately with` the pinion 20 of the uptrain, for which purpose the two gear- wheels 22 and 23 of the downtrain are mounted upon the rocker H,wl1ereon the piece or small plate 25, which is secured to the rocker by a screw, 26, affords appropriate bearings for one end of each of the spindles for said gear- wheels 22 and 23.

The pinions 20 and 24, respectively, of the uptrain and the downtrains are set at such distance apart that the rocker can be turned one way to bring the pinion 20 of the uptrain in engagement with the gear-wheel 11, but throw the pinion 24 of the downtrain out of engagement with the gear-wheel 11, after which the rocker can be turned to throw pinion out of engagement with gear-wheel 11, but bring pinion 24 into engagement with said gear-Wheel 11, which has its spindle 12 journaled at one end in the stationary plate A, with its opposite end journaled in and passing through a bearing-piece, 27which is fixed to the plate A, and over which the dial C is placed. It will be observed that the plate forming the rocker H is cut away at points to provide space for certain of the gear-wheels, as will be readily understood without further description.

The adjustment of the rocker for alternately bringing one and the other of the two trains into engagement with the gear-wheel that is xed on the spindle of the winding indicatorhand G is effected automatically. To such end I provide a spring, 28, which is secured within a recess in the plate A, and having a tendency to bring the rocker into position to throw the pinion 20 into engagement with the gear-wheel 11 on the winding indicator-hand spindle, and thereby permit said gearfwlieel 11 to be actuated from the barrel during the operation of winding up the Inainspring.

In drawing out the winding-spring F the Vpull thereof on the barrel will turn the latter in a direction against the force of the mainspring D, and hence in thus opposing and overcoming the resistance of the mainspring the spring 28 will be left free to throw the rocker into position to bring the pinion 20 of the uptrain thereon into engagement with the gearwheel 11 of the winding indicator-hand, and thereby permit the winding indicator-hand to be turned in a direction to denote the extent to which the mainspring is wound up. As soon, however, as the mainspring has been wound up and the operator has released the winding-spring, or permitted the same to retract within the case, the force of the mainspring will cause the rocker H to shift to the other extreme of its limited play, and thus permit the pinion 24 of the downtrain to be brought into engagement with the gear-wheel 11 on the winding indicator -hand spindle, thereby allowing the winding indicator-hand to be turned from the arbor 1in a direction to denote the condition of the mainspring as it runs down.

The barrel gear-wheel 29, Figs. 1 and 6, is arranged opposite one end of the barrel, but is independent of the barrel and secured by screws 30 to the arbor 1, to which latter the inner end of the mainspring D is attached. This barrelwheel 29 is consequently driven by the mainspring, and serves to move the train that is to be driven from the mainspring in the usual way.

The regulator-arm 31, which is employed for adjusting the usual hair-spring,32, and which engages the said hair-spring in the usual way, is pivotally held at one end, and at its opposite end bent inwardly or provided upon its inner s ide with a projection for engaging in the spiral groove 33,that is formed in one of the sides or faces of a pivoted disk, 34. (Represented in Figs. 1, 3, and 4.) This groove 33 commences adjacent to the central portion of the disk 34, and from thence runs outwardly from and eccentric to the axis of the disk until at or near the circumference of the disk, at which point the groove runs around the face of the disk concentric with the axis thereof.

By turning the disk 34 the regulatocarm will be adj usted by reason of its engagement with the spiral portion of the groove 33 in said disk, the object in forming the outer portion of the groove 33 concentric with the axis of the disk being to prevent the regulator-arm from being adj usted either to an undue extent or to an extent which might force it out of engagement with the regulating-disk.

The regulating-disk has a pivot or journal extending from both of its two sides or faces, one of its said journals being applied to turn in a bearing provided by the bridgeplate B, which, as shown in Fig. 4, drops toward the plate A., and is formed so as to afford a halfcircular seat or recess for the regulating-disk, as illustrated in Fig. 4, taken in connection with Fig. l. The other journal, 35, of the regulatingdisk 34 is designed to extend into a hole to be formed through the usual back cap at a point where the journal will be received in such hole when the back cap is closed.

In order to more effectually exclude dust from entering at such point the journal 35 of the regulating-disk 34 is provided with an annular shoulder, 36, Fig. 4, which, when the back cap is closed, will lie against the inner face of the back cap. The outer end of the journal 35,which is thus visible through the back cap, is provided with a scale or circular index,which will be used in conjunction with index 37 on the back cap, as in Fig. 4a, wherein asmall portion of the back cap I is shown with the scale upon the journal of the regnlating-disk visible-through the same.

The journal 35 of the regulating-disk can be provided with one or more holes, 3S, in which a pin or any convenient pointed instrument can be engaged for turning the regulating-disk without the necessity of opening the back cap and exposing` the works ofthe watch.'

As shown inFigs. 15, 1G, and l7,the pivotal end of the regulator-arm 3l is provided with a split ring, 39, which is fitted to turn in an annular groove, 40, formed in the inner side of the bridge-piece 41, that is secured to the plate A.

The hand-setting stem K is arranged to work through the casecenter and over the upper or back-cap side of the plate A. This stem K is provided at its inner end with a pinion, 42, which engages in one of the two lines of gear-teeth of the minute-wheel L. (Represented partially in full and partiallyin dotted lines in Figs. 8 and 9 and in full lines in Fig. l1.) Vhen the hand-setting stem Kis drawn out to a certain extent, as shown in Fig. 9, its pinion will engage in the annular line of gear` teeth 43 of the minute-wheel L, so that the stern K can be turned for the purpose of operating the minute-wheel. Vhen, however, the handsetting stem is pushed in,-the pinion 42 on stem K will be brought about over the center of the minute-wheel, so as to stand centrally Within and free of the annular line of gearteeth 43.

The hand -setting stem K is subject to a catch or locking spring, M, Figs. l, 9, and 11, secured at one end to theplate A, and arranged with its free end across the handsetting stem at a point within the watchcase. The plate A is provided with two fixed studs or pins, 44 and 45, which rise from the plate and stand alongside the hand-setting stem adjacent to locality where the spring M crosses said stem, and the said stem is provided with a short tapered portion, 46, of which the contracted end terminates at a shoulder, 47, the taper of this said portion of the hand setting stem being toward its inner end. When the hand -setting stem is at its inner position, so as to place the pinion 42 at its inner end free from engagement with the upper annular line ofgear-teeth 43 ofthe minute-wheel,the spring M will lie within the notch formed by the aforesaid taper 46 and shoulder 47 of the handsetting stem, as in Fig. 11, the spring in such case bearing against the shoulder 47 and thereby serving to keep the hand-setting stem in its inner or back position. lNhen, however, the hand-setting stem is drawn out, so as to bring its pinion 42 into engagement with the annular gear 43 ofthe minute-wheel, as in Fig. 9, the shoulder 47, acting against the spring M, will draw the free end thereof over the pin 45, the under side of the spring being beveled, as shown, in order to permit it to ride over said pin during such operation. rIhe spring, after riding over the pin 45, drops between .the two pins, of which the pin, 44, nearest the periphery of plate A serves as a stop for preventing further outward movement of the spring, and hence for limiting the extent to which the hand-setting stem can be drawn out, while on the other hand the pin 45 prevents the spring from returning to its normal position and allows the spring to keep the handsetting stem in its outer position so long as may be necessary. After turning the stem K to an extent to properly set the hands the stem can be pushed in or back to its inner or back position, during which movement the inclined face of its tapered portion 46, acting against the beveled under side of spring M, will lift the spring to an extent to permitit to ride back over the stop-pin 45.

Vith regard to the minute-wheel L, it may be observed that its lower line of gear-teeth 48 engage the usual cannon-pinion 49,(sec also Fig. 2,) fixed on an arbor, 50, which carries the minute-hand, the hour-hand being carried on an hourwheel,which turns on a hub of the cannon-pinion in the usual way. The usual center pinion,5l, is drilled through its center for the passage of the arbor 50, which said arbor is split, as in Figs. 6 and 7, so as to give it spring frictional contact with the center pinion and at the same time permit the arbor to be readily turned independently of the center pinion for the purpose of setting the hands. It is understood that the center pinion, 5l, is driven from the mainspring through the usual or any desirable and appropriate gearing, and that when so driven it carries with it the arbor 50,as usual. It may also be observed that the small pinion 52 (herein shown on the minute-wheel L) is the pinion usually employed for moving thehourwheel.

In order to avoid all liability of the handsetting stem being left in its out position after it has been drawn out and turned for setting the hands, I can provide a safety device, consisting of a catch or pin, 54, Fig. 19, arranged in position on the edge portion of the front cap,N,of the watch-case, to engage a bevel or taper, 53, on the hand-setting stem when the stem is out and the cap is being closed, said catch or pin acting during the closing ofthe case to force back the hand-setting stem.

In Fig. 2 I have shown a common form of stop-wheel, 54, serving to arrest the rotation of the barrel at a time when in winding up the mainspring the latter has been wound up to the proper tension. As indicated in dotted lines in said figure, the gear-wheel 2l has on its under side a disk-shaped hub provided at a point along its periphery with a segmental IOO IIS

notch. The gear-wheel 21 is further provided on its under side with a pin,which stands back from the wheel at a point opposite the middle of the segmental notch, as also indicated in dotted lines.

It is understood that the rotation of the barrel or the arbor brings the radial arms or teeth of the stop-wheel successively into engagement with the pin, and in each instance' the stop-wheel is given a partial turn, except at the engagement with the pin of one particular tooth formed as in the usual star-Wheel stop device, at which juncture the said tooth cannot pass, the pin being stopped at the corner of the disk alongside the pin in the usual way.

The winding spring F, hereinbefore described, serves, when drawn out by the pullbutton 6, simply as a fiexible cord, strip, or band, which, being wound around the barrel, serves, when pulled out and unwound, to rotate the barrel for the purpose of winding up the mainspring. As a provision for restoring such fiexible strip to its normally-coiled condition upon the barrel, I preferably make it of spring metal and provide its inner end with a tooth, 3, for engaging in a line of ratchet-teeth around the barrel, as hereinbefore described; but I believe it is novel with me to provide a watch wherein the mainspring can. be wound up by pulling out a strip, or the like, that is coiled around the barrel, whether the restoration of such strip to its originally-coi1ed condition is effected by the inherent elasticity of the strip or by other means which may suggest themselves to the skillful watch-maker. Hence, while I regard the provision of a winding-strip having` inherent spring force to restore it to its normally- Wound condition upon the barrel after the winding has been effected as a part of my invention, I also desire to be understood as covering the feature of a flexible strip for winding up the mainspring, as aforesaid, whether said strip be recoiled by its own spring-power or by springpower auxiliary to the strip.

What I claim as my invention is- 1. In a watch-movement, the combination of the barrel having its periphery provided with ratchet-teeth, and the mainspring coiled in said barrel,with a flexible springstrip having its inner end provided with a hook adapted to normally bear against said ratchet-teeth and its outer end provided with a pull-button, whereby said strip is adapted to be drawn out from the watch and uncoiled to turn the bar- :rel and wind up the mainspring, substantially as described.

2. In a watch-movement, the combination of the dial-plate A, having a channel cut therein, the barrel having its periphery provided with ratehetteeth,and the mainspring coiled in said barrel, with a flexible spring-strip having its inner end provided with a hook and bent to normally engage with said ratchet-teeth and adapted to be drawn out and uncoiled to wind up the niainspring and to be returned withits hook sliding over said ratchet-teeth to resume its normal coiled condition within the watch, substantially as set forth.

3. The combination, with the mainspring, the barrel, and the windingindicator-hand, of the rocker II, carrying the two sets or trains of gearing, one being the uptrain, driven from the barrel, and the other the downtrain,driven from the arbor of the mainspring, a gear carried by the spindle of the winding indicatorhand and in position to be alternately engaged by one and the other of said two trains of gearing, a spring, 28, tending to throw the rocker into position to bring the uptrain into engagement with the gear-wheel on the winding indicator-hand, and the winding-spring for turning the barrel,so as to wind u p themainspring, and in so doing relieve the rocker from the tension ofthe mainspring and permit the spring 28 to shift the rocker, which latter when subject 'to the tension of the mainspring is shifted in an opposite direction by the same, substantially as described.

4. The combination, with the pivoted regulator-arm for regulating the hair-spring,of the rotary disk provided with a spirally-formed groove wherein the regnlator-arm engages, said spirally-grooved rotary disk being provided with a hub, 35, which is received in an opening through the back cap when thelatter is closed, substantially as described.

5. The combination, with the pivoted regulabor-arm for regulating the hainspring, ofthe rotary disk provided with a spiral groove, wherein the regulatorarm engages, said spially-grooved rotary disk being provided with a hub, 35, having on its outer endascale which is visible through the back cap when the latter is closed, substantially as described.
