A New, Cheap and Si7nple Apparatus for repeating the Hours, 

 and Quarters in Clocks and Watches, By Mr, J.M. Elliot. 

 Communicated by the Inventor, 



JL HE great expence of repeating watches in the firft pur- New and fimple 

 chafe, as well as in the fubfequent repairs, have induced Mr. repeating mo- 

 Elliot to turn his thoughts towards reducing their conftru6lion 

 to a greater degree of (implicity, and confequently to dimi- 

 nifh the charges in both thefe refpeds. 



In the mechanifm reprefented in plates VII. and VIII. the 

 parts and their arrangement are fuch that without the ufual ap- 

 paratus of pinions, pullies, chains, or racks, the watches re- 

 peat both the hour and the quarters, viz. the hour firft and the _ 

 quarter afterwards, or the hour or the quarters feparately; or ^ 

 either of thefe firft as may be wilhed, without interruption, 

 and by one hammer. As feveral of thefe pieces have been 

 made and difpofed of in this country as well as exported, the 

 pradlicability as well as the coft are both afcertained, which laft 

 is about one third of the former charges. 



Plates VII. and VIII. reprefent the parts of this new ma- 

 chinery. Fig. 1. fhews the principal pieces as attached to the 

 upper pillar plate by means of a pottance A B C D, called the 

 repeating pottance, kept to its place by the fcrew x, — a b fhews 

 the pendant attached to a fteel axis upon which the repeating 

 apparatus is fixed and carried. In the adual time piece thefe 

 parts are as clofe to each other as convenience will allow ; but 

 ihey are here reprefented for the fake of difiin6tnefs, as if at 

 a difiance from each other. Tims, they are made to a6t and 

 perform the ftriking by turning the axis of the pendant to the 

 fight or left.
