ALARM-CLOCK.

SPECIFICATION forming part of Letters Patent o. 391,802, dated October 30, 1888.

(No model.)

To @ZZ whom 176 may concern:

Be it known that l, ALMEnoN M Linn, a citizen of the United States, residing at Meriden, in the county of New Haven and State ot Connecticut, have invented certain new and useful lmprovementsin Alarm-Clocks, of which the following is a specification.

My invention relates to improvements in alarm-clocks ot` the class in which the alarminovement is constructed separately from the eloclrmovement and located within a different part of the clock; and the object of my improvement is to so connect the alarmmovement with the holding and releasing mechanism of the clock as to more conveniently locate said parts, whereby they may be placed in a position to render the alarm more effective and to give a better appearance to the clock.

In the accompanying drawings, Figure l is a reverse plan view of my alarm-clock. Fig. 2 is a partial vertical section of the same on the line .fr .r of Fig. 1. Fig. 3 is an enlarged horizontal section of a portion of the same on line g/ 1/ of Fig. 2. Fig. 4 is a horizontal section of the vibrating arm and the holding and releasing arm on linee e of Fig. 3; and Fig. 5 is a front elevation of detached parts illustrating a slight modilication.

A designates the clock-case containing the movement oi an ordinary construction, and B the base upon lwhich said clock -ease is mounted. Underneath this base at one end I mount an alarm-bell, C, and at the other end an alarm-movement, D, which in the main is of an ordinary construction. This alarmmovement is mounted with its movementplates in a horizontal position, and consequently the eseapenient or verge which carries the hammer 6 is upon a vertical shaft, 7.

Pivoted upon a suitable stud, 8, on the base B is a vibrating angle-lever, 9, having an upwardly-projecting rod or arm, 10, which extends at right angles to said anglelever up into the movement of the clock by the side of the holding and releasing arm 11. I eennect said angle-lever with the vibrating hammer-arm and verge by means of a link, 12, whose ends are pivoted, respectively, to said angle-lever and hammer-arm. In some cases l may make the linl; :d iustableby forming it of two pieces, one of which is slotted and the other of which receives the threaded end of a holdingserew, 13, whereby said two parts of the link may be adjusted one upon the other in the ordinary manner ol" a slotandserew adjustment, but such adjuslability is not essential.

The holding and releasing arm 1l within the clock-ease is a spring-arm with the portion which surrounds the center shaft, 1l, of the cloclemovement pressing against one of the dial-wheels15,said wheel being so mounted as to slide longitudinally willi the center shaft. Said wheel is also provided with a cam, 1G, against which a pin, 17, on the setting-wheel 1S bears. The alarnrpointer 19 is connected with the hub of the setting-wheel, andthe setting-wheel meshes into a pinion, 20,whieh is turned by moving the settingbutton 21. ,Vhen the hour arrives for which the alarm is set, the pin 17 slips oll' the shoulder of the cam 16 and permits the lower end of the holding-arm 1l to spring forward,thereby throwing it out of the path of the laterallyvibrating arm or rod 10, which arm or rod,by reason of its link-connection with the hammer-arm or verge and the angle-lever, necessarily vibrates laterally with the vibratory movement of the hammer.

In some eases it may be desirable to set the alarm-movement with its vergeshaft in a horizontal instead of a vertical position. ln such a ease l employ the angle-lever shown in lFig. 5, in which the laterally-vibrating arm l0 is integral with the lever and projects upward in the same plane as said lever, instead of at right angles thereto. It is, however, connected with the alarm bythe link 12, and the arm 10 extends up by the side of the holding and releasing arm 11., so that the operation is the same.

Heretofore l have made an alarm-elocl without the link and angle lever, in which cloel; the laterally-vibrating arm or rod pro jected upwardly from the verge or hammerarm to the holding and releasing arm of the clock, the alarm and clocl; movements, sep arately considered, being the same as herein shown and described.
