JNO. F. MASCHER, OF PHILADELPHIA, PENNSYLVANIA.
ALARM-CLOCK.
Specification of Letters Patent No. 22,883, dated February 8, 1859.
To all whom it may concern:
Be it known that I, JOHN F. Miisorrnn, orn the city ot Philadelphia and State ot Pennsylvania, have invented a neu7 and'usetul Improvement in ClocksVhereby rlhey May be llviade to Strike at any Desired nterval ot Time; and I do hereby declare that the following` is a full, clear, and exact description ot the same, reference being had to the annexed drawings, making a part oit this specilication. in Which- Figure l, is a :t'ront vieuv ot' my improvet clock. Fig. 2, is a side vieuv ot the same. F ig. 3, is a front view ot' the several parts added to an ordinary clock by ine.
My invention consists in applying a ratchet or other shaped pinion or Wheel A to the arbor of one of the Wheels ot the going part of a clock as herein shoivn to the arbor of the third Wheel, one pivot ot said arbor having,l its bearing in a slotted shaped hole B, in the trame.; said pinion t meshing into the rack C having' its center ot motion at D.
A sp ing secured to the clock trarne is used tor the purpose ot throwing` the rack back against the snail F Whenever Ythe pinion A is disengaged from the teeth ot the rack C, by means ot the lever Gf, and through the instrumentality ot the striking,` part of the clock, one end ot said lever being pressed aside by each pin in the pin or strike Wheel K, of the clock as said ivheel rotates, the other end of the lever lifting the arbor ot Wheel A out of place by means of the motion imparted to the lever by the pin Wheel ot the striking part of tie clock.
The rack C is used in part Jfor the purpose of unlocking the striking part ot the clock, through the instrumentality of a detent lever H, and it also in conjunction vvith the pinion A and snail F serves to divide the hour or any portion of time into minutes, and it required halt or quarter minutes, a spring l secured to the traine serves to keep the pitching ot the pinion A and rack C engaged during such times that the clock is not striking'.
The brass hand J is secured to the sleeve ot the snail and is used to change the time ot striking, the tigures upon an ordinary clock dial serving an index for that purpose, the hub ot the snail is a tube, fitting' spring' tight upon a tube securely fastened to the traine. the axis ot the snail, minute and hour hands ot the clocks are concent c, as the hand is moved from one ig'ure upon the dial to the other a corresponding i l is presented to the legl step i ot' the snail of the rack, the highest step in this case corresponds to one minute and the loivest to ten minutes, but prefer twenty-tour steps or divisions upon the snail to correspond Awith from one-halt to twelve minutes so that the clock is capable to strike either one or twenty-tour times per tvvelve minutes.
The rack in the case under consideration unlocks the strikingpart by direct action, but in some cases it may be desirable to do that duty bj: recoil acti The cio-cl; so constructed is designed to be used for the purpose of timing and startpxseugfer railroad cars. oinnibuses.I and other vehicles, which require to be started at regular and irregular intervals ot time, and also for timing,l the exposure ot' daerreotypc and other photographic pictures. ffc.
do not claim either the rack, snail separately, but
l claim- The application ot the rack pinion and snail in the manner set forth to the going partot` a clock or Watch tor the use and purpose described.
