I ALFRED DE BOTTON of 26 Dickinson Street Manchester in the County of
Lancaster, Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved clock or time piece to which is applied a
continuous and perpetual calendar which is actuated by simple clock work
dependent on the minute wheel work.
The apparatus is set in motion at the raising of the catch of the striking
inovement at midnight and is worked by a double acting spring box.
On the arrival of the finger at the hour of midnight the date of the day is
changed even if the clock should be stopped.
It is also provided with mechanism by which the regulation or movement of the
days can be effected even when the time piece is stopped, and such motion does not
interfere with the regular changes of month and date effected by the action of the
clockwork.
This calendar marks automatically the day of the week, the date, and the month
whether of twenty-eight thirty or thirty-one days besides which, every four years,
it indicates the twenty-ninth day of February of the bissextile or leap year.
The mechanism which I employ to carry out my invention is constructed and
arranged in the following manner.
The calendar as before stated is actuated from the minute wheel work preferably
by a shaft upon which is mounted a toothed wheel gearing with the "minute-
pinion" which drives the hour wheel and making one revolution in every 24 hours.
Upon this shaft is a tappet which at each revolution releases a spring catch upon
a vertical shaft from a fixed projection or stop and allows the said vertical shaft to
make one revolution before being arrested by the said projection or stop. This
vertical shaft is actuated by a quick threaded worm keyed or fixed thereon driven
by a worm wheel which is carried round by a spring pawl and ratchet wheel on the
main spring or barrel arbor in connection with the ordinary going-barre! of the
clock work, the spring of which is thus double acting, and serves both for the clock
or time piece and for the calendar.
The spring catch upon the vertical shaft can be released also by a hand lever
and thus the date calendar which is worked by this vertical shaft can be changed
even when the clock is stopped (when the main spring is wound up) either by the
minute hand or by this hand lever.
Upon the vertical shaft is a worm actuating a worm wheel upon the shaft or
axle of a seven faced barrel on each face of which is printed or marked one of the
days of the week; (Monday, Tuesday, etc.).
The worin and worm wheel are in such proportion that at each complete revolu-
tion of the vertical shaft the week day barrel will make one seventh part of a
revolution and so alter the date.
The worm wheel is loose on the barrel shaft but is mounted between two discs
fixed on the said shaft and is provided with seven holes or notches into one of
which a spring pin on one of the aforesaid discs engages; thus whether the clock
is going or stopped this week day date can be adjusted or altered by hand by
turning the spindle or shaft of the barrel the end of which is squared or otherwise

page_text: formed for a key to fit upon; the spring pin running over the holes or notches
in the worm wheel (which remains stationary) until the required day is visible
through an opening or window in the frame or front of the clock.
Below the last named worm on the vertical shaft is mounted a pinion which is
loose on the shaft but is capable of being keyed thereto by a catch pivotted to the
wheel and engaging (at the time and in the manner hereafter described) in a groove
in the said shaft the pinion being capable of rising or falling for a short distance
on its shaft.
The pinion is provided with a grooved boss in which works a fork fixed to a
spring bolt or vertical spindle hereafter described, and the said pinion is made
sufficiently broad to be constantly in gear with a toothed wheel mounted upon a
barrel which revolves upon a vertical axis, and it is so proportioned to this toothed
wheel that at each revolution of its shaft it causes the latter and its barrel to make
part of a revolution and gradually wind upon the said barrel a band or ribbon
unwinding the same from a spring barrel at the other side of the frame. Each
motion presents to view a fresh date of the day of the month marked upon the said
ribbon or band. When the last day in the month has been shewn, at the next
change of date a projection is so set and fixed upon the upper side of the toothed
wheel of this date barrel that it will come against the catch which holds the pinion
keyed to the vertical shaft and will release the said pinion. The spring at the
other end of the ribbon or band can then wind back the latter until the 1st date of
the month is shewn when the projection on the toothed wheel will again come in
contact with the catch and key the pinion to the vertical shaft thereby arresting
further winding of the band or ribbon on the spring barrel.
As. including leap year, there are four different ds of month namely months
of 28 29 30 and 31 days, there are four projection of different heights on the
toothed wheel for causing the return of the date ribbon or band, the projection for
changing the month at the end of 28 days being the shortest and that for the
31 days the longest and the height of the pinion upon the vertical shaft is regulated
by the spring bolt or vertical spindle before mentioned the lower end of which rests
upon a cam hereafter described in order to release the catch according to the
month shown by a barrel with twelve faces upon which are marked the names of
the said months. The axle or shaft of this last named barrel is provided with a
ratchet wheel having 12 teeth corresponding with the 12 faces shewing the
months and held in position by a spring catch; it is moved one tooth forward
every time the band or ribbon is wound back by a swivelling frame carrying a
catch or bar which engages in the teeth of the said ratchet wheel and is mounted
upon a nut moving upon a screw thread on the spindle of the band or ribbon
barrel which changes the date. As the numbers advance the catch or bar is
lowered by the nut until it falls below one of the ratchet teeth and when the month
is ended and the ribbon or band is wound back the reversal of the direction of
motion of the screw raises the catch or bar and turns the wheel one tooth forward
thereby shewing a fresh face on the month barrel.
This at the same time changes the position of the cam upon the axle of this
barrel and adjusts the height of the spring bolt or vertical spindle which regulates
the position of the catch upon the pinion which ensures the winding back of the
band or ribbon as before described at the proper day when the ensuing month shall
be ended.
The position of the month barrel can be altered if required without moving the
rest of the mechanism by raising the catch or bar and frame on its pivot and partly
turning it to remove it from the ratchet wheel, when the axle of the said barrel is
free to be rotated by a key or otherwise.
Thus each part of the calendar can be adjusted separately and independently of
the clockwork.
The 29th day of February is shewn every fourth year by a star wheel mounted
at the bottom of the February depression in the cam on the month barrel axis.

page_text: The motion of the cam beneath the spring bolt above named causes the latter to
move this star wheel one tooth forward every year; and every fourth depression
between the teeth of this star wheel is less deep than the others and prevents the
end of the spring bolt from falling so far as the other depressions allow thus causing
the releasing pin of the 28th day to pass under the releasing catch of the band or
ribbon above named and to be released by the pin of the 29th day instead.
The clock or time piece as well as the plates for indicating the date, the month
and the day, may be made of any suitable material and the inscriptions of the
calendar may be in any language.
Dated the 22nd day of December 1892.

COMPLETE SPECIFICATION.
A Combined Calendar and Clock.
Communicated from abroad by JULES MARIUS GIUILI, of 16, Traverse du
Chapitre, Marseilles, France, Merchant.
I ALFRED DE BOTTON of 26 Dickinson Street Manchester in the County of
Lancaster, Merchant, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to an improved clock or time piece to which is applied a
continuous and perpetual Nendar which is actuated by simple clock work
dependent on the minute wheel work.
The apparatus is set in motion at the raising of the catch of the striking
movement at midnight and is worked by a double acting spring box.
On the arrival of the finger at the hour of midnight the date of the day is
changed even if the clock should be stopped.
It is also provided with mechanism by which the regulation or movement of the
days can be effected even when the time piece is stopped, and such motion does not
interfere with the regular changes of month and date effected by the action of the
clockwork.
This calendar marks automatically the day of the week, the date, and the month
whether of twenty-eight thirty or thirty-one days besides which every four years it
indicates the twenty-ninth day of February of the bissextile or leap year.
The mechanism which I employ to carry out my invention will be readily under-
stood from the following description to which I have annexed two sheets of
illustrative drawings.
On Sheet 1 Fig. 1 shows a front elevation of a clock with my invention applied
thereto.
On Sheet 2 Fig. 2 is an elevation of the mechanism seen from the back with the
casing removed.
Fig. 3 is a side elevation shewing the front of the clock in section and parts of
the mechanism removed or in section.
Figs. 4, 5, 54, 5B, and 6 are views of detached parts hereafter more particularly
referred to.
The calendar as before stated is actuated from the minute wheel work preferably
by a shaft a upon which is mounted a toothed wheel gearing with the "minute
pinion" c which drives the hour wheeld and making one revolution in every twenty
four hours.
Upon this shaft a is a tappet a¹ which at each revolution releases a spring catch e
upon a vertical shaft f from a fixed projection or stop el and allows the said vertical
shaft to make one revolution before being arrested by the said projection or

page_text: stop e. This vertical shaft f is actuated by a quick threaded worm f¹ keyed or
fixed thereon driven by a worm wheel which is carried round by a spring
pawl and ratchet wheel on the main spring or "barrel arbor "/" in connection
with the ordinary going-barrel of the clock work, the spring of which is
thus double acting, and serves both for the clock or time piece and for the
calendar.

The spring catch e upon the vertical shaft can be released also by depressing a
hand lever see Fig. 2 and thus the date calendar which is worked by this vertical
shaft can be changed even when the clock is stopped (when the main spring is
wound up) either by the minute hand or by this hand lever f.
Upon the vertical shaft is a worm 8 actuating a worm wheel upon the shaft
or axle of a seven faced barrel i on each face of which is printed or marked one
of the days of the week (Monday, Tuesday, etc.) see Figs. 1, 2 and 3.
'
The worm and worm wheel are in such proportion that at each complete
revolution of the vertical shaft the week day barrel i will make one seventh part
of a revolution and so alter the date.
The worm wheel is loose on the barrel shaft but is mounted between two
discs and fixed on the said shaft and is provided with seven holes or notches
see Figs. 3 and 4 into one of which a spring pin 10 on one of the aforesaid discs
engages. On the drawings the disc is shown divided by a curved line to form
the spring which carries the pin 10. Thus whether the clock is going or stopped
this week day date can be adjusted or altered by hand by turning the spindle or
shaft of the barrel the end of which is squared (see Figs. 2 and 3) or otherwise
formed for a key to fit upon; the spring pin 10 running over the holes or notches
in the worm wheel 2 (which remains stationary) unt the required day is visible
through an opening or window A in the frame or fB of the clock.
Below the last named worm 8 on the vertical shaft is mounted a pinion k
which is loose on the shaft but is capable of being keyed thereto by a catch
pivotted to the pinion and engaging (at the time and in the manner hereafter
described) in a groove in the said shaft the pinion being capable of rising or
falling for a short distance on its shaft.
The pinion is provided with a grooved boss see Fig. 2 in which works a fork /*
fixed to a spring bolt or vertical spindle hereafter described, and the said
pinion is (as shewn) made sufficiently broad to be constantly in gear with a
toothed wheel m mounted upon a barrel 'n which revolves upon a vertical axis, and
it is so proportioned to this toothed wheel m that at each revolution of its shaft f
it causes the latter and its barrel n to make part of a revolution and gradually
wind upon the said barrel na band or ribbon n unwinding the same from a spring
barrel n at the other side of the frame see Fig. 2 and detached plan Fig. 5.
Each
motion presents to view a fresh date of the day of the month marked upon the
said ribbon or band n¹.
When the last day in the month has been shewn, at the next change of date a
projection m² m² m² or m² is so set and fixed upon the upper side of the toothed
wheel m that it will come in front of and in contact with the catch which holds the
pinion keyed to the vertical shaft f and will release the said pinion k as seen on
the detached view Fig. 5. The spring barrel n² at the other end of the ribbon or
band can then wind back the latter until the first date of the month is shewn,
when the projection m' on the toothed wheel m will again come in contact with the
catch and as it is moving in the reverse direction see Fig. 5" it will key the
pinion to the vertical shaft thereby arresting the further winding of the band
or ribbon n' on the spring barrel ². The difference of the speed or motion of the
projections m³ m² m² m² and the projection I causes the barrel n and pinion k to
make several revolutions before contact occurs.
As, including leap year, there are four different kinds of month, namely months
of 28, 29, 30 and 31 days, there are four projections m'm² m³ m' of different
heights on the toothed wheel for causing the return of the date ribbon or band, the

page_text: projection m for changing the month at the end of 28 days being the shortest and
that m for the 31 days the longest and the height of the pinion k upon the vertical
shaft is regulated by the spring bolt or vertical spindle before mentioned the
lower end of which rests upon a cam o hereafter described in order to release the
catch according to the month shown by a barrelp with twelve faces (see Figs 2
and 3) upon which are marked the names of the said months. The axle or shaft p¹
of this last named barrel p is provided with a ratchet wheel på having twelve teeth
corresponding with the twelve faces shewing the months and held in position by a
spring catch p; it is moved one tooth forward every time part of the band or
ribbon n is wound on the barrel n' by a hanging frame carrying a catch bar or
screw which engages in the teeth of the said ratchet wheel pand is mounted
upon a nut p moving upon a screw thread on the spindle n³ of the band or ribbon
barrel which changes the date. As the numbers advance the catch bar or
screw p is lowered by the nut p until it falls below one of the ratchet teeth and
when the month is ended and the ribbon or band n' is wound back the reversal of
the direction of motion of the screw n³ raises the catch bar or screw pt and turns
the wheel one tooth forward. thereby shewing a fresh face on the month
barrel p.
This at the same time changes the position of the cam o upon the axle of this
barrel and adjusts the height of the spring bolt or vertical spindle which regulates
the position of the catch upon the pinion k which ensures the winding back of the
band or ribbon n² as before described, at the proper day when the ensuing montli
shall be ended.
The position of the month barrel p can be altered if required without moving
the rest of the mechanism by raising the catch bar or screw pt and frame on its
pivot and partly turning ito remove it from the ratchet wheel, when the axle pl of
the said barrel is free to be rotated by a key or otherwise. The said axle p' is
squared at the end for that purpose.
P
Thus each part of the calendar can be adjusted separately and independently of
the clockwork.
The 29th day of February is shewn every fourth year by a star wheel o' mounted
at the bottom of the February depression in the cam on the month barrel axis see
detached view Fig. 6. The motion of the cam o beneath the spring bolt above
named causes the latter to move this star wheel o' one tooth forward every year
and every fourth depression between the teeth of this star wheel o' is less deep than
the others as seen at o' and prevents the end of the spring bolt from falling so
far as the other depressions allow, thus causing the releasing pin m' of the 28th day
to pass under the releasing catch of the band or ribbon above named which will
be released by the pin m³ of the 29th day instead.
It will be understood that for months of 30 days the pinion k will be so raised
that m¹ and m² pass below the catch which will be released by m³ and for months
of 31 days the latter will pass beneath the catch which will be then released by
the pin mt.
The clock or time piece as well as the plates for indicating the date, the month
and the day, may be made of any suitable material and the inscriptions of the
calendar may be in any language.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1st. The general construction and arrangement of mechanism (substantially as
hereinbefore described and illustrated by the annexed drawings) forming a com-
bined calendar and clock each part of the former being adjustable separately and
independently of the latter.
2nd. The combination of mechanism, substantially as hereinbefore described and
illustrated by the annexed drawings for winding back the date ribbon or band and

page_text: changing the month at the twenty eighth, twenty ninth, thirtieth, or thirty-first day
according to the number of days in the month indicated, thus automatically
indicating the twenty-ninth day of the bissextile or leap year in its due time.
Dated this 12th day of April 1893.
