Improvements in Combined Clocks and Calendars, and in
Calendars.
I THOMAS SLAITER Mechanical Engineer 4 Lisburne Road Gospel Oak
London do hereby declare the nature of this invention to be as follows:-
On the body of an ordinary circular clock of American or other type, I place a
number of light dial plates, bored so as to fit on the body of the clock but free to
turn easily when required. These dial plates are of different diameters and I
divide and mark the outer part of the face of one of them so as to represent all the
days of the month. The face of the next dial plate is divided into a corresponding
number of divisions but these divisions are marked with the names of the days of
the week in succession, week following week. A third dial plate is divided and
marked with the names of the months and on this dial plate may also be marked
the number of days in each month. The two dials, one of which shews the names
of the days of the month and the other the days of the week in succession are
connected together by means of one or more readily removeable small screw pins
with nuts.
Thus the divisions on the dial marked with the names of the days of
the month are set against the divisions marked with the names of the days of the
week on the other dial and remain and shew so throughout the month. The
clock body is further provided with three fixed small discs or collars, the first of
which is provided with a vertical pointer. The dial shewing the names of the
months is placed between the first and second of these small discs or collars, the
two connected dials being placed between the second and third or back one.
method of working the combined clock and dials is as follows-
The
At the commencement of the month or whenever the calendar is to be put into
use, the dial marked with the names of the months is to be moved until the proper
month be under the vertical pointer. Then the screw pins which connect the
before mentioned dials together are to be removed and the dials moved until the
first day of the month on one dial appears against the proper day of the week on
the other. This must be ascertained from an almanack or from a table shewing
upon what day of the week the first day of every month will fall which can be
affixed to the back of the dials.
The two dials are again to be connected together by the small screw pins and
are then to be moved round on the body of the clock until the proper date and day
are vertical under the pointer where the name of the month already appears and
these connected dials require to be moved forward one division each day.
If the clock be one of 24 hours, this will be a very simple matter and can be done
babitually after winding up the clock every morning.
I may further add a front disc on the body of the clock, leaving the face exposed
and having a vertical slot in the upper part so as to shew the date, day, month &c.
The remainder of the disc to be filled with useful information or advertisements as
desired.
In my second arrangement of calendar, 1 dispense with the clock, using the two
dials bolted together as before, one dial shewing the days of the month and the
other the days of the week. The smaller of the two dials is also marked with the

page_text: names of the months and also with the hours of the day. This calendar is provided
with fingers like an ordinary clock, the smaller finger to be moved monthly so as to
point out the month whilst the longer finger requires moving every day so as to
point out the day of the month and week. The two dials also require correctly
setting before putting into use as in the case of the previously described arrange-
ment. I may further add an intermediate disc marked with a series of numbers.
The front dial would be perforated to shew one of these numbers which with three
others appearing on the front dial would represent the years.

I THOMAS SLAITER, Mechanical Engineer of Silverleigh, Constantine Road,
Hampstead, London formerly of No. 4 Lisburne Road, Gospel Oak, London do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
Firstly An arrangement of dials turning freely on a circular body or distance
ring connecting a frontal disc having apertures to shew the days, dates and months
and a back cover. This frontal disc, distance ring and back cover are bored out
so as to fit tightly on to the body of a circular clock of American or other type,
leaving the face exposed and forming with the dials a perpetual calendar around it.
The back cover is further provided with a hinged foot which with the frontal disc
enables the whole to stand on a table. The dials are of different diameters and I
divide and mark the smallest so as to represent the months. The face of the
second dial is divided into thirty five, representing five complete weeks and these
divisions are marked with the names of the days of the week in succession. The
third and largest dial is similarly divided, thirty one of these divisions are marked
to represent the dates of the month. But I do not claim the invention of dials
divided in the manner I have adopted.
The construction and arrangement is as follows-
On the distance ring between the frontal disc and back cover, I insert a second
distance ring to the face of which I attach a dial of the months of the same
diameter and to the back I attach a cover. These are connected together and
bored so as to turn freely. This back cover is provided with projecting studs for
the purpose of moving the dial of the months. On this second distance ring and
between its back cover and the frontal disc, I insert a third distance ring to the
face of which I attach the dial of the days of the week and to the back I also
attach a cover, the whole connected together and bored so as to turn freely. This
back cover is provided with projecting studs for the purpose of moving its dials
every morning. The dial of the days of the week is larger in diameter than its
distance ring and on this distance ring in the space between the dial and the back
cover, I insert the dial of the dates of the month, fitting somewhat tightly between
so as to be carried round by them but capable of being turned on the distance ring
when the dials require to be set. If necessary, I further connect these two dials
by means of a readily removeable small screw pin or otherwise, after the dials are
set. Thus, the dial of the months is attached to a distance ring and back cover
which are moveable on the fixed circular body or central ring of the frontal disc.
The dial of the days of the week is attached to a distance ring and back cover which
are moveable on the distance ring of the months and the dial of the dates is
i

arrangement of calendars.
The whole substantially as herein before described.
Dated this 19th day of March 1895.
