Letters Patent for this invention have been 'granted to me as follows: France,deposited April-16,1883, granted Lugust 3, 1883, No. 151,905; German Einpire,deposited November 10, 1883, granted May 5, 1884, No. 26,971; Italy, deposited December 6, 1883, granted December 15, 1883, Vol. XVII, No. 16,181, Vol. XXII, No. 15S.
This invention relates to an alarm-watch in which but one spring is used to actuate'the time and alarm mechanism; and my improvements relate to the means' l'or winding up the spring, to the mechanism for setting the hands and the alarm, and to the alarm mechanism, all as hereinafter described.`
In the drawings, Figure 1 is a'view of the front ot'y the watch, theworksbeing detached from the case and the main and alarm dialsv partly removed. Fig. 2 is a vieu-'at the rear oithe watch, with the capplate that covers thewinding gear and 'resilier removed. Fig. 3 is an eleva-tion oi'v said cap-plate. a diagramillustrating the gearing of thetime mechanism. Fig. 5 represents the device for limiting the striking ofthe alarm, and Fifr. (i is an elevation of the double rocker detached.
The springbarre-l has teeth at B that gear into a pinion upon the central arbor of the watch, and by the wheels 1, 2, and 3,`and pinions upon the shafts of 2 and 3, motion is communicated to the escapement wheel 4 and balance 5. This arrangement of gearing, as. well as thegearing i'or giving motion to the hour and minute hands, is ot' the usual character.
a is a rocker that occupies a recess in the plate b3, and its pivot a is at the center of said plate. This rocker carries a wheel, a, that is always in gear with a wheel, o, upon a squared portion of the winding and setting stem f, and c isa spring that bears against said rocker, and moves said rocker to thelel't, Fig. 2, and causes the wheel u to mesh with a wheel, t, upon the arbor a "t the spring- Fig. 4 is i vmove as one wheel.
barrel. Then the wheels tand narein gear, as shown in Fig. 2, the main spring can be wound up by turning the stem ci Z) is a lever for moving the rocker-plate a to the right, Fig. 2, and'disconnecting the wheels tand u for apurpose hereinaiter explained, and d is a cap-plate (shown detached in Fig. 3 and bydottcd lines in Fig. 2) that keeps the rocker a., wheel u, and leyer I; iuplace. The cap-plate d presses upon the lever b with sufiicientforce to hold said lever in'the position to which it may bc moved. In consequence of the rocker a. having its center o." motion at the center ot' the pillar-plate,the wheela, can ried b y said rocker. gears with the wheels v and t under the most favorable conditions.
Beneath the dial c ot' the watch thereisa double-acting rocker, f, carrying the wheels g, l1., i, and j, and said rocker is pivoted at di. The wheel 7L is uponsaid pivot Rand is always in gear with the wheels t', i, and g, and the wheels t' and j areA upon the saine stud and Z and 7s are 1Hishvpins. Their inner ends are connected with said roekerfand their outer ends project through the ring ot' the watclr. case, so that theyr` can be pressed upon by the finger to swing the rocker. XVhen the pin l is pushed in, theroeker is moved .and the vwheel j brought into gear with the minute; wheel k2, and in this position the hands can be set by turning the `stem at through the medium of the wheels c, h, ,j, and It. W'hen the h'ngcr is removed from the pin 1,the spring z returns the rocker to its normal position, disconnecting the wheelsj and tf". Vhen the pin k is pushed in,the wheel g is brought into gear with the wheel q, and in this position the dial e* can be turned for setting the a'larm,the stem a? acting through the wheels o, h, g, and q. The. is a notched disk, y, connected to the Wheei q by the pin 12, and said wheel q has a tubular hub surrounding the cannon ot' the hour-wheel and revoives with it by friction,- and the dial e* sets upon a tubular hub ofthe disl ',1/; hence the wheel q, dish y, and dial e4L all revolve as one with the hour-wheel once in every twelve hours, but said parts can be turned without moving said hourwheel when the wheels g and c are in gear for setting the YI OO and at the saine time thepin e is released. by

When the leverrests against the periphery of this disk l, as Vshown by dotted vlines in Fig. 1, the other end of the lever is in the path afa pin, e', upon the hammer e, and prevents the hanr mer being 'vibrated /Vhen' the disk has revolvedsothat its notch comes opposite the tooth 25, then the spring L moves the lever tothe position shown by full lines in Fig. l, the tooth passing into the notchin the disk,

ment-wheel sf acting upon the pins 1- i' and the alarm sounded' by the hammer e striking the steel wire Z. rDheeseapement wheel s is upon the arbore?, that receives its motion from the spring-barrel through the wheels 6, 7, and S.' The wheel 6 is loose upon the arborI of the spring-barrel, so as not to be revolved when the spring is heilig wound up; but when the lever s -releases'the pin 'e" then` this wheel 6 is revolvedby the ratchetwheel a, that is fast to the arbor d', acting upon the pawl 14, that' is pivoted yto the wheel G. Thespring-b-inrel is of a size to furnish six and one-half turnsv of winding, of which three' turns are for the alarm. Thebalancc enables the watch to lrun for thirty hours. R is a linger upon the arbor of the springl the plate b Vhen the alarm is striking, the segment is turned one tooth during each revolution of the arbor a' until the segment is turned tothe position shown in Fig, hwhere the further movement of the arbor a is arrested, and the alarm stops striking. The pins yr r, forming lthe recoil-e`scape1nent. are made with semi-cylindrical heads for the teeth of the Aescapementwheel s' to act against, and with circular bodies entering correspondingly-shaped holes in the hammer c. By turning these pins around in their holes their adjust' ment is effected to regulate the working of the escapement. I
To prevent the alarm vstriking when the, watch is in the pocket, I providea spring, a, having a projecting part, a, against which'the case strikes when the case is closed, thereby forcing the free end of the spring against the hammer e and preventing said hammer being moved by the eseapement-wheel s.. rihis arrangement necessitates leaving the ease open when the watch is placed uponatable or other support and it is desired to have the alarm sound. The ,stemy @Zand wheel o revolve when the alarm strikes if the wheels u and t' are in gear. lt is therefore preferable to disconnect these Wheels a and t by the lever b, the outcr/ end of which passes through the case and the inner end acts upon the rocker a.
If the stem l is allowed to turn, its crown may catch in the watch-chain and prevent the alarm striking. f the niainspring of the watch is fully wound up, and it is desired to set the hands, then 'the lever b must be moved to disconnect the gears a and t; otherwise the hands cannot be set. If the spring is only partially wound up, then the act of setting the hands only winds up the spring further, and there is no necessity for disconnecting the wheels u and t. In setting the alarm the stem and wiieel o are turned to the left in the direction ofthe n1otion ofthe hands, and as this motion doesl not wind up the spring it is iinn'iaterial whether the wheels u and t are in gear 'or not. The spring 'n might be replaced by the lever m, (shown by dotted lines in Fig. 2,) 'said lever to be moved bythe finger to bring its inner end in or out ofthe teeth of s and prevent or allow the alarm 'to be rung, as desired;
I claim as my invention- ,1. The rocker a, pivoted at the center ofthe watch, in combination with the'wheel u, carried by said rocker, the spring-barrel and its wheel t, the stem a?, and wheel u, substantiall y as and for the purposes specified.'
2.

3. The double rocker-plate f, the wheels h, i, j, and g, the ste-m a?, and wheel o, the handsetting wheel k2, the alarm-dial 6*, gear Q, and notched disk y, substantially as set forth.
