SPECHCATION forming part of Letters Patent No. 383,260, dated May 22, 1888.

Application filed Drcember 20, i886. Serial No. 222,070.

To @ZZ w/"Lom it may concern:

Be it known that I, JUs'rrN Walzen, of ChauX-de-Fonds, Switzerland, have invented an Improvement in ltepeating-lVatehes, (for which l have received a patent in Belgium, dated May 3l, 1386, lo. 73, 178,) of which the vfollowing is a speciiication.

rEhe object ot' my present invention is to provide a repeating mechanism of simple eonstruction that can be applied to ordinary stem winding and setting watches and be operated by he winding and setting stem after the sounding mechanism has been brought into position i'or action by the turning of a button upon the watchAcase ring.

In the drawings, Figure l is an elevation of the watch with the dial-plate removed and with the parts of the repeating mechanism out of action. 2 is a similar view with the hands and quarter-wheel removed and with the repeating mechanism in position for striking the hours. Fig. 3 is a section ofthe striking mechanism at about the line .o tr, Fig. 2, without the case. Fig/l is an elevation showing the arbol-s oi" the hour and minute hands and the spring-pawl that controls the striking mechanism. The gearing for actuating the striking mechanism is shown by dotted lines in this ligure, and Fig. 5 .is an elevation of a portion ol' the stem winding and setting mech anism and of the device for throwing said mechanism out oi' action when the repeating mechanism is thrown into action.

The winding and setting stem A is provided willi a crown, A", as usual, and upon asquared portion ol the stem is a clutelrwheel, B, the ratchetteeth 3 ol' which normally meshes with the similar teeth on the pinion G, that is loose upon said stem. This pinion Cis always in gear with the wheel AQ, and this latter meshes with the teeth upon the spring-barrel A of the watch. This wheel A5 and springbarrel A are shown by dotted lines in Fig. 5. There is a third wheel, D, upon the winding and setting stem, and said wheel D is upon a squared portion of said stem and always turns therewith, and said wheel D gears into the wheel E of the train of gearing F G H, that actuates the sounding mechanism. 'When the parts are in the position shown in Fig. 5, the mainspring can be wound up by turning the crown A and its stem through the pinion C, wheels A5, and gear-teeth upon said spring- (No model.) Patented in Belgium May 31, i886, No. 73,178.

barrel r When the push-piece XV is pressed fully in, the ratchet-teeth 3 of the pinion B are disconnected from the pinion C and the teeth e'. are moved into gear with the wheel B of the hand-setting mechanism, and thehands can be set by turning said crown and its stem. When the wheel B occupies an intermediate position and is not in gear with either the pinion C or the wheel B, as shown by dotted lines in said Fig. 5, then the turning oi" the crown and its stem actuales only the repeating mechanism.

The wheel G is upon the swinging plate O, the pivot of which is the axis o ofthe wheel F, and said wheels D, D, F, and G are always in gear with each other; but the wheels G and H are in gear only when the plate O is moved to bring the repeating mechanism into operation, as hereinafter explained. This plate O also carries the hammer-tail 0, pivoted at g, and having a springshank and the hammer U for striking the hours. The spring o', that is screwed at one end to the plate O, acts en the tail O to cause the hammer to strike.

The wheel lil is fitted to turn loosely upon the hub L of the arbor L2 of the hour-hand, and this wheel H is kept in place by the plate l), that is screwed to the main plate ol' the watch. Said wheel 'l has a circular flange, H', passing up through a circular opening in said plate P, and the wheels M N are secured to the wheel H by screws a n a passing into 0 holes at 'm m in., Fig. el, in said flange H. These wheels Il hl N turn as one wheel.

The wheel hi has twelve teeth and actuates the hammer U i'or striking the hours, and the wheel N has forty-eight teeth and actuates the hammer a i'or striking the quartenhours. The arbor L'l of the heur-hand passes freely through a central hole in the wheels lil N, and in the hub L of said arbor .lf there is a notch forming a stop at Z for a pawl, K, to take against. rlhis pawl l is pivoted to the wheel H, and a spring, J, keeps the outer end of said pawl against the hub L".

lt is now to be understood that in the normal condition ofthe watch the wheels H, M, and N are stationary, but that they can be rotated by turning the crown A. and its stem alter the plate 0 is moved and the wheels B C disconnected, and the wheel G brought into gear with the wheel lil. he amount of the rotation of said wheels H, M, and N, however, is limited by the pawl K coming in contact with the stop Z on the arbor of the hour-hand. Thus, if the hour-hand has just passed 1 on the dial, the wheels H M N can be turned only onetwelfth of a complete revolution,when the end of the pawl K will come in contact with the stop Zand arrest their further rotation. As the wheel M has twelve teeth, it willbe turned but one tooth, and the hammer-tail O will be moved once by the tooth of the wheel M and only one blow be given by the hammer U upon the sonorous wire or sounder V, thereby indieating that it is one oclock. lf the hand has just passed 2 on the dial, the stop Z will be at such a distance from the pawl K that the wheels H M N can be rotated one-siXth of a complete revolution before their rotation is stopped by the pawl K coming against the stop' Z; hence the wheel M will be turned two teeth, the hammer-tail O acted on twice by the teeth of the wheel M, and two blows be given by the hammer U upon the sounder V to indicate that it is two oolock. In like manner the other hours are struck.

Vhen the wheels H M N are rotated, the barrel I is also rotated by the wheel H gearing into the teeth upon said barrel l', and a spring within that barrel is wound up, and the function of this spring is to return the wheels H M N after each striking operation to the normal position they occupied before the repeat-ing mechanism was brought into operation. L

Before explaining how the 'quarter-hours are struck it is necessary to first describe how the repeating mechanism is brought into action.

The swinging plate O is connected to a le ver, R, by the link Q, and one end of said lever R is within a groove of the cam S, which cam is at the inner end of a stud, s, that passes through the watch-case center, and at the outer end of this stud s there is a turn-button, T, for rotating said stud and cam. The button T and parts operated by it occupy the position shown in Fig. 1 when the repeating mechanism is out of action; but when the button T, stud s, and cam S are given a quarter-rotation by turning the button said cam acts through the lever R and link Q and swings the plate O into the position shown in Fig. 2, bringing the hammer-tail O between two of the teeth of the wheel M and the gears G and H together. At the same time a pin, O2, on the plate O is brought against the spring-lever YV and shifts the ratchetwheel B to its intermediate position, (indicated by dotted lines in Fig. 5,) so that the crown A3 and its stem can be turned for rotating the wheels H M N through the wheels D E F G, and the hour struck, as aforesaid, without the winding or setting mechanism being operated bythe turning of the crown and stem.

The hammer-tail X', carrying thespringshank and hammer u for striking the quarterhours, is pivoted at X2 to the swinging plate X and is actedupon by the spring Said plate X is pivoted at x to the watch-plate, and it is connected to the lever Z by the link Y. After the hour has been struck, as before described, the button T must be given a further tation of said cam does not move the lever R.

To strike the quarter-hours: Suppose the watch indicates twenty minutes past two. The button T is turned and then the crown and stem are turned, as before described. The

wheels H M N will be rotated, so that the wheel M turns two teeth and a third before the pawl K is arrested by the stop Z, and the hammer-tail O' will be lifted twice and two blows be given by the hammer U. As soon as the hours are struck the crown and stem must be released before giving the second quarterturn of the button T. As soon as the crown and stem are released the spring-barrel I turns back the wheels H M N one-third ofa tooth of the wheel M, when the rotation of said wheels is arrested by the tooth of the wheel M that last lifted the hammer-tail O coming in contact with said hammer tail, Du ring this back ward movement of the wheels H M N the pawl K was carried away from the stop Z. The crown and stem are now to be turned in the same direction as rst turned, (the button T having first been given its sccond quarter-rotation,) and the wheels H M N are rotated the same distance forward as they were turned backward by the spring in I-viz., one-third of a tooth of the wheel M or one and one-third tooth ofthe wheel N-beforethe pawl K again comes in contact with the stop Z, and in so doing the hammer-tail Xis moved once and one blow is given by the hammer a upon the sonorous wire V, thereby indicating that the minute-hand of the watch is between the quarter and thehalfhour. Ifthe minute-hand is between the half and the three-quarter hour, then the tooth of the wheel M thatlastlifted the ham mer-tail O passes beyond it a distance equal to two tooth of the wheel N, and the hammer-tail X will be lifted twice and two blows be given by the hammer u. If the minutehand is between the hour and the rst quarter, then the tooth of the wheel M that last lifted the hammer-tail O will not move beyond the same a distance equal to one tooth of the wheel N. Consequently when the crown and stem are turned the hammer-tailX will not be lifted to its full extent and no blow will be given by the hammer u, and the person operating the repeater will know that the minute-hand has not passed the first quarter-hour. When the IOO IIO

button T is turned back to the position shown in Fig. 1, the cam S acts through the leversR and Z to return the parts to the normal position shown in Fig. l, with the wheel G disconnected from the wheel H, the clutch-wheel B connected to the pinion C, and the hammertails X clear of the teeth of the wheels M N. As soon as said hammer-tails are clear of said wheels the spring-barrel I rotates the wheels H lll N back to the position they oeeupied bel'ore the repeating mechanism was brought into operation. A pin, t', upon the spring-barrel l, coming in contact with the plate P at t?, limits the return movement of the wheels H lll N and insures their stopping` at the proper place. This pin t', by coming in contact with the plate l) at t3, prevents the wheels H H N being turned more than a complete revolution in their forward rotation.

ln order te insure the button T being held in any one of the three positions to which it can be turned, l provide three notches at S' in the cam S, and into one of these notches, according to the position of the button, passes the hooked end ot' a spring, S, and holds said button securely from accidentaldisplacement, but allows for the button being turned by the thumb and lnger.

l claim as my invention-- l. ln a stem winding and setting watch, the combination, with the stem A4 and the wheels B, C, and D, of the wheel E, the swinging plate O, wheels F and G, hammer-tail O', and hammer and pin O2, means, substantially as specified, for moving the plate O, the clutchlever XV, the hour--eannonL astop upon said cannon, the wheels H and M, the pawl K, and spring J, carried by said wheel H, the spring barrel l and pin upon the spring-barrel, and stops l'or limiting the rotation ot' the barrel, substantially as speeilied.
