Mover of the Watch did bend the other again 5 fince it will bene 
matter in this way, whether it bend again more or lefs fpeedily, fo 
it bend only again before the other have done unbending ic felf ; 
and confequcntjy, the one delivering the other at the end of its 
motion, this play will always continue aniforp, and fo by letting 
go, ac every turn or period of thefe two Springs, a tooth of a 
wheel carriedabQutby the ordinary, Auptior^ vvhigh counts fe- 
conds or other parts of time, equal to the periods, we fliall have 
fiicha Watchasisdefired by us. ' 
Thefe thoughts of mine I have executed in the following man- 
p. J ner|j: Let ABbeoneof the Watch-plaresj C andM. 
ySee ig. ♦ two indented barrels, wherein the fmall Springs are 
ineloffed; Th€ teeth of the barrels Catch thofe of the pignons 
d;d. which carry the bal lances e/e ; and other teeth of the faid 
barrels are catcht by thofe of the interrupted wheel F Now 
let us imagine, that this wheel FG, being moved towards HF by 
the force of the firft Mover of the Watch, and turning the bar- 
rel bends the Spring inclofed in it, and flops with the 
barrel as foon as it hath bent this Spring* This piece which ferves 
to ftop, is eafie, and hath not been thought neceffary to be marked 
here, to avoid embarafling the Figure. But vvhilft one indented 
part of the interrupted Wheel pG, viz. F. turns the barrel C, 
the empty part, oppofed thereunto, which is G, anfwersto the o- 
ther barrel M, and gives liberty to^the Spring, it iucl0feth,to un- 
bend it felf. Thus whilft the movement of the Watch bends the 
fmall Spring of the barrel C, in the fame time the finall Spring of 
the other barrel M, unbends of it felf. I fay, w the fame time^ 
except the Spring C fiiaU have done bending a little Doner, than 
t-he Spring M liall have imbent it felf; So that the Spring C. be- 
iiigbent, and t be Wheel FG flopped ; both of them flay in this 
poiture, till the Spring M, when it ihall be quite unbent, do, at 
the end of its motion, touch a piece which delivers it. And then 
the Spring C unbends of it felf in its turn ; the teeth of the inter- 
rupted Wheel, which continues its motion the fame way as before, 
fince 'ti delivered, not being any more able to hinder it there- 
from, becaufe the barrel C doth now meet Vv'ich the empty part H 
of the faid Wheel. But before it hath.done unbending it felf, the 
indented part L', being oppofite to the empty part H, that turns 
she barrel M, -bends its Spring again, and having done fo, flopps 
^^ith ir, whilll: the Spring C, making an end of unbending it felf, 
i delivers
