As clearly seen in Fig. '7 the end 69° of the
lever 69 is enlarged into segmental form to carry
a spring ?nger /I2I and is provided with an in
10 wardly bent forked lower end I2IX which is in
circumferential alignment with the pin II6.
It will be noted by referring to Figs. 17 to 19
that the cam bars 96, 99 and I00 are provided
with heads I22, I23 and I24 which are some-e
16 what triangular in form, the broad base por

to the distance between the outer ends of the

The gear 56 is secured to the shaft .55 as is
also the cam 51. The rotation of the cam 51
trips the tripping ?nger 59 once in every twenty
four hours‘ (see Fig. 4). The tripping ?nger 59
is secured to the shaft 56 as is also the escape

which is then driven by the spring 4i until the
pin 46 engages the projection 6I° of the detent

releases the pin 46 at SIX. When the cam 51 trips 15
the finger 59, the spring 60 swings the ?nger 59
towards ‘the shaft 55 and thereby rocks the de

Furthermore when the pawl Bl returns‘upward,
‘its frictional contact with its ratchet wheel would
fa not be su?lcient to turn the ratchet and shaft if
connected directly to such shaft and also carry

When the “day of the month” wheel is set by
hand, the pin 241 is engaged by the shoulder H
(see Fig. 35) as the sleeve I52 is rotated. If the
knob IN is rotated too‘ far when the pin 241 is
in engagement with the shoulder H, the rotation
15 of the knob i8>< may be reversed so that the
shoulder G engages the pin v241 to carry the indi—
cating wheels to the correct position.
.
Similarly when the day of the Weekv wheel is
, set by ‘hand, the pin 251 is engaged by the shoul
20 - der ofthe collar l53>< corresponding to the shoul?
der H of the sleeve I52 as the collar is rotated.
If the knob l'lX is rotated too far when the pin
251 is in engagement .with the aforesaid shoulder,
rotation of the knob "X may be reversed so that
25 ‘the .shoulder of the collar i53>< corresponding to
the shoulder G of the sleeve I52 engages the pin
251 to carry the day of the week wheel to the
correct
position.

From, this description it willbe seen that I
30 have devised means actuated from a time clock
for successively indicating from day to day the
days of the week, days of the month, months and
' years forming an automatically operated calendar
for a long period of years such as ?fty years to
which the foregoing device as illustrated is
adapted.
_
What I claim as my invention is:
1. In a calendar mechanism, a month wheel
' and a “day of the month” wheel, a main sup
thirty day month extending from the face of
the month wheel and bearing against the thirty
day cam when the corresponding month indi
cation is in the viewing position to positively hold
the said thirty day cam against the “day of the
month” wheel, a movable pin also extending from
the face of the month wheel and bearing against
either the twenty-eight or twenty-nine day cam
when a twenty-eight or twenty-nine day indica
tion is in the viewing position to positively hold
the corresponding cam against the "day of the
month” wheel, a spring held pin extending
through the "day of the month” wheel, and
means coacting with the aforesaid cam. bars and
pins for forcing said last named pin outwardly 15
into the path of the outer end of the recipro~
eating main lever to be engaged thereby to ro
tate'the “day of the month” wheel a plurality
of day spaces, and means operated from the year
wheel for moving the twenty-eight or twenty 20
nine day or movable pin into position to engage
the corresponding twenty-eight or twenty-nine
day .cam.
