ALARM CLOCK .AND WATCH.

Specification of Letters Patent.

Patented Dec. 12, 1911.

Application led September 30, 1905, Serial No. 280,808. Renewed Februaryll, 1911. Serial No. 608,396.

To all whom it may concern:

Be it known that I, CHARLES Louis FAivim, watchmanufacturer, citizen of Switzerland, residing at Le Locle, Canton of Neuchatel, Switzerland, have invented new and useful Improvements in Alarm Clocks and Vatches, of which the following is a specification.

This invention relates to alarm mechanism for application to clocks or watches and consists in cert-ain devices for locking and releasing the usual vibratory hammer and also manually operable means for effecting the release of the hammer', to operate the alarm, at a predetermined time.

The invention will be more fully described in connection with the accompanying drawing and will be more particularly pointed out and ascertained in and by the appended claims.

In the drawing Figure 1 is a view of the manually operable means for setting the alarm. Fig. 2, is a reverse view. Fig. 3, is an enlarged sectional View on line A-B of Fig. 2. Fig. 4, is a sectional view on line C-D of Fig. 3.

Like characters of reference designate similar parts throughout the different figures of the drawing.

As shown in the drawing A portion of the time train is indicated in Fig. 2 by wheels l, 2, 3, t and 5, said wheel 5 meshing with a barrel pinion 6 actuated by a spring 7. IVheel Z, Figs. l and 3, is fast to the arbor of the hour hand, (not shown), and meshes with and is positively driven by wheel o, of equal diameter, which is mounted on arbor 7c. A wheel c, equal in diameter to wheel o, is also mounted on arbor la and is held thereby in frictional contact with wheel o to afford relative adjustment of the former with respect to t-he latter.

An improved adjusting or setting means is provided for adjusting the setting wheel 7c which consists of the following construction. A swinging or adjusting member s, preferably in the form of the bell crank lever, is pivotally mounted at t to the pillar plate b or other stationary part and carries at r a wheel p adapted to mesh with the setting wheel c and a wheel Q, adapted to rotate with the wheel j) and in mesh with a manually operable wheel o rotatably mounted at t. Said member s is provided with an extension u, adapted to normally project through the case, diagrammatically indicated by line e. As will be seen by reference to Fig. l, the manually operable wheel o also projecting beyond the case. A spring a engages the swinging member s and serves to normally hold the wheel p out of mesh with wheel 7c. An index 7a2 secured to t-he wheel 7c rotates abreast of a graduated portion 7c3 visible to the operator, so as to indicate the position to which the wheel 7c has been set.

When it is desired to set the alarm mechanism the operator presses inwardly on the extension u against the action spring fr while forcing the wheel p into mesh with the wheel 7c. Wheel c is then set by rotating the manually operable wheel o. A striker or hammer i is pivotally mounted at t" in a bridge 2 and in the pillar plate and is operated from a spring barrel 7 through the medium of wheels, 4, 5, 6 and a ratchet wheel 3 and escapement pawl 8 which latter are mounted at z". A gong a is secured to the pillar plate Z) by the mounting 'n' in striking proximity to the hammer Said hammer z' is provided with a projection L, Fig. 4, adapted to be engaged byapin f provided with a knife edge f and held thereby in a retracted position. The pin is mounted in one end of the lever c which is secured at its opposite end to a spindle or arbor o. A bridge a mounted on pillar plate supports the lever c and forms a bearing for the arbor o. Said arbor c extends through the pillar plate Z) and carries on its opposite end a hand or index d. Said index d extends from the arbor c toward the wheel 7c and into the plane of travel of a lug m mounted on said wheel. The disposition of the parts just described is such that when the lug mengages the index l the latter serves through the arbor c and lever e to throw the pin f out of engagement with the project-ion 7L releasing the hammer z' and permitting the same to operate under the action of the independently driven alarm train hereinbefore described.

When the striker is engaged by the pin f and held in a retracted posit-ion it is desirable to provide means serving to hold the pin f in enga-gement with the shoulder h and it is necessary that said means permit of disengagement of the pin f from the projection h when the lug m engages the index (Z and to this end said means is designed to yieldingly engage the lever c or other suitable part connected with the pin f. As

shown a spring is provided having forked arms g which engage the lever e at opposite sides. Said arms g terminate in a base g rigidly secured to the bridge a. In assembling the parts the base g is mounted upon the bridge a in a manner to cause the arms g to normally hold the pin in engaging proximity to the projection 7L as clearly shoivn in Fig. 2.

l claim l. A device of the class described comprising in combination a gong, a striker therefor, a. pivotally mounted lever for holding said striker in a retracted position, a spring yoke engaging said lever on opposite sides to hold it in locking relation with said striker, and a frictionally act-ing gear train for displacing said lever.

2. A device of the class described comprising in combination a gong, a striker therefor., a pivotally mounted lever for holding said striker in a retracted position, a spring yoke engaging said lever on opposite sides to hold it in locking relation with said striker, a positively driven pinion, and an adjustable pinion frictionally driven by said first-mentioned pinion and cooperating with said lever to release said striker.
