I, ALFRED LUGRIN, of Orient-de-l'Orbe, in Switzerland, Watchmaker, do hereby
declare the nature of this invention to be as follows:-
My invention consists of a new mechanism for repeating watches, striking the
hours, quarters, and minutes.
My repeating mechanism is actuated by a rack which gears into a pinion fixed upon
the axis of the striking spring-barrel. Upon said axis there is further affixed a finger or
eccentric which is intended to withdraw a pinion which turns freely upon the same
axis, and which is provided with a pin against which bears the said finger or
eccentric. The aforesaid pinion' gears into an inner toothed range with which the
opening of a rack of peculiar shape is provided, the outer edge of which is furnished
with the teeth causing the striking of the quarters and minutes.
The travel of said rack is limited on the one hand by the snail of the quarters, and
on the other hand by means of a rack provided with 15 teeth, which hooks itself on
to a pin affixed upon the first mentioned rack. A minute snail, provided with
15 steps, and carrying a pinion moved by means of a wheel which is affixed to
the minute-wheel, and which causes the said pinion to make 4 revolutions an
hour, is placed so as to cause the hooking of the rack on to the pin with the
tooth corresponding to the number of minutes which are to be struck.

page_text: I, ALFRED LUGRIN, of Orient de l'Orbe, in Switzerland, Watch Maker, do hereby
declare the nature of this Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following statement
(reference being had to the accompanying drawings, and to the letters and figures
marked thereon) that is to say :-
My invention relates to a new mechanism for repeating-watches striking the hours,
quarters, and minutes, and will be readily understood on reference to the accom-
panying drawing which illustrates a watch provided with said mechanism.
My mechanism is acted upon by a pusher P, formed like a knee lever and provided
with a spring p. The arm P₁ of the pusher P bears upon the prolongation A¹ of a
rack A which gears into a pinion B fixed upon the axis C of the sounding or striking
spring-barrel. The travel of the rack A is limited by the hour snail K which is fixed
to the star wheel L having a break and turning one tooth for each hour. Upon the
axis C, of the sounding or striking spring-barrel, there are further mounted a seg-
mental rack R, having twelve teeth, and an eccentric D which is intended to withdraw
a pinion E which turns freely upon the same axis C, and which is provided with a
pin e, against which bears the said eccentric D. The rack R strikes the hours by
acting upon the projection n of the hammer axis N. The pinion E gears into the
inner toothed range with which the opening of a peculiarly shaped rack F is provided,
the outer edge of which is furnished with teeth causing the striking of the quarters
and minutes by acting upon the projections o and s of the hammer axes N and S.
The travel of the rack F is limited, on the one side, by the quarter snail G, and on
the other by means of a rack H, carried by the lever H', said rack being provided
with fifteen teeth, so as to hook itself on to a pin h fixed upon the rack. A minute
snail J, formed with four arms each provided with fifteen steps to limit the stroke of
the lever H', and fixed to the minute wheel, is placed so as to cause the hooking of
the rack H on to the pin h by the tooth corresponding to the number of minutes
which are to be struck by the teeth f of the rack F acting upon the projections of
the hammer axis S.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same may be performed, I declare that what I
claim, is:-
1. The combination of the rack A, on the one hand, with the hour snail K. and on
the other hand with the pinion B, the rack R, and eccentric D fixed to the axis () of
the sounding or striking spring-barrel, and with the pinion E turning freely upon
said axis and provided with a pin e which is acted upon by the eccentric D, sub-
stantially as and for the purpose specified.

page_text: 2. The combination of the pinion E with the rack F having an inner toothed range
gearing into the pinion E, and an outer toothed range so arranged as to strike the
quarters and minutes, and with a lever H' bearing a rack H hooking itself on to the
pin of the rack F by one of its teeth determined by the minute snail J, substantially
as and for the purpose specified.
3. The minute snail J fixed to the minute wheel and formed with four arms J, each
having fifteen steps for limiting the stroke of the lever H³, substantially as shewn and
described,
