ALARM-CLOCK MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 267,619, dated November 14, 1882.

Applicntion'filed December 19, 1881. (Model.)

To all whom, it may concern: l either shaft C or F may be turned to wind its Beitknown thatLWALDOL.UPsoN,ofMeri respective spring independent of the other, 55

declare the following, when taken in eonnec- The train of gearing between the main timetion with the accompanying drawings and the wheel D and the pointers is of the usual ar- 6o letters of reference marked thereon, to be a rangement, and needs no further description full, clear, and exact description of the same, than to say that L is the center shaft upon io and which said drawings constitute part of whichthepointers arearranged. On this shaft,

This This invention relates to an improvement in hollow shaft (l is provided with a pinion, e,

NVith the pinion c rangement ofthe main wheel for the alarm on and vergewheel f thus arranged upon the a tubular shaft on the shaft of the main wheel, center shaft, they occupy no additional space 75 the shaftof the main wheel extending through over what is required for the time-movement. the tubular shaft of the alarm-wheel, so that The hammer-shaft is applied within the space the shaft on the main wheel may be turned to of the time-movement, so that, in fact, the adwind the spring of that wheel through the ditionofthealarm,withitsindependent spring. tubular shaft of the alarm-wheel; second, in is made with no greater width and height of 8o the arrangement of the verge-wheel, which opthe movement than would be required were era'tes the hammer, loose on the center shaft; the alarm not pre-sent.'

3o third, in the arrangement of the setting-shaft m is the set-ting cam-shaft, which passes through the time-pinions, all as more fully herethrough the time-pinions a, so that the shaft inaftcr described. becomes the center or bearing on which the 85 A represents the front and B the rear plates time-pinions a revolve, these pinions a beingI ofthe movement, secured togetherinthe usual the same as usually employed between the manner. C is the main shaft, upon which is hour and minute pinions on the center shaft the main driving-wheel D, provided with the to communicateA the di'erential revolution to usual spring, E, the outer end ofthe main shaft the hour and minute hands. The shaft m is 9o C constructed of polygonal shape, as at a, or provided at its front end with a pinion, l, otherwise, for the application of the windingworking into the hour-pinion s on the center 4o kel;r thereto, so that by turning the shaft the shaft, so that the rotation of the hour-hand is spring will be wound in the usual manner. imparted to the shaft on. This shaft extends O11 the main shaft C is a tubular shaft, F, through the movement to the rear, and is there 95 which takes its bearing in the rear plate, and provided with thel setting-cam t, with which extends outward around the main shaft. On an arm, a, from the hammer-shaft engages unthis tubular shaft F is the main alarm-wheel til the fall-ol on the cani permits the arm from Gr, provided wit-h its independent spring H, the hammer-shaft to escape. Thus the alarm one end ot' which is attached to the tubular is sounded. This cam is adjusted by turning roo shaftFandthe other to the wheel G,in the usual it upon its shaftin the usual manner, the dial manner.- The outer end of the tubular shaft thereon indicating the position of the cam in 5o F is fitted with a hollow key, I, by which the the usual manner. This tripping mechanism, shaft F may be turned to wind the spring, the being concentric with the time-pinions, also shaft provided with the usual pawl and ratchet comes within the space required for the timeto hold the spring, as seen in Fig. 2. Thus movement. This concentric arrangement of the two independent springs may be employed in the time and striking movement as well as in time and alarm. I therefore do not wish to confine this part of my invention to an alarm mechanism.

It is not essential that the verge-wheel and its pinion should be arranged concentric with the center shaft7 as they may be otherwise arranged and yet preserve the main wheel concentricwiththetimemainwheel. li'lyinvention is therefore not to be limited to the combined arrangement of the main wheel and the verge- Wheel or setting-shaft.

I am aware that two independent wheels have been arranged upon the same shaft, each to have a movement independent of the other, and therefore do not broadly claim such construction or arrangement; but

l. The combination of the main time-Wheel, its shalt and spring7 with a second and main wheel and its independent spring', arranged upon the shaft of the main wheel, with a tubular extension or shaft from thesaid second main wheel, outward and around the shaft of the main time-Wheel, by which said tubular extension the spring` of thel second main wheel may be Wound, leaving the main shaft eX- posed to Wind the time-spring7 substantially as described.

2. The combinaion of the verge-wheel of the alarm and its pinion, arranged and loose upon the center shaft of the time part, with mechanism, substantially such as described7 to impart revolution to the verge-wheel independent of the center-shaft, substantially as described.

3. In a combined alarm and time movement, the combination of the setting-shaft m, arranged concentrically through the pinions a, which connects the hour and minute pinions on the center shaft with the pinion 1' on said setting-shaft, in connection with the hourpinion s on the center shaft, substantially as described.

4. In acombined alarm and time movement,

the combination of the alarm main wheel and its independent spring, arranged concentric with and loosely upon the main shaft of the time part, the said alarm main wheel contructed with a tubular shaft extendingoutward and around the main shaft, whereby either springmaybe Wound independent ofthe other, with the alarmverge and its pinion arranged concentric and loosely upon the center shaft of the time-movement, substantially as described.
