We, HARRY LOUIS ROSENTHAL, of 41 Ackers Street, Manchester, Jeweller, and
ELIOT LEVY, of Lewis's, Market Street, Manchester, Merchant, do hereby declare
the nature of our said invention to be as follows:-
Our invention consists of a combined date Calendar and puzzle, or a date
calendar which can be used as a puzzle, or by which the dates of all the Fridays,'
or any other days of the week, for the whole year, or for any part thereof,
can be seen at a glance, or by which same calendar, provided the day and month
are known, the date can be ascertained, or if the date and month are known the
day of the week can be readily found. This said combined calendar and puzzle
also forms an advertising medium.
In carrying out our invention we employ a number of, by preference, cubical
blocks or pieces, and for the purpose of the date calendar comprising 31 pieces,
all consecutively numbered from 1 to 31, and for the purpose of the puzzle com-
prising three further pieces, but not numbered and left plain. The numbers of
these pieces run laterally and with the pieces marked (8), (15), (22) and (29)
arranged directly beneath the piece marked (1), therefore producing five lines of
numerals. These 34 pieces (with the addition of another piece for the purpose of
keeping them in a permanent position when used as a Calendar, but which is
removed for the purpose of the puzzle) are placed in a shallow box or frame, and
in, or about, this same box or frame, or an extension thereof we mount a series of
tablets or plates (by preference seven) each of which bears the name of a day of
the week, and the current year. These plates or tablets are also divided by rect-
angular lines into two rows of spaces or squares which in the case of say Friday
and the year A.D. 1897 will be divided and marked with the name of each month
in the following manner: —
The peculiarity of this date Calendar is that according to the tablet placed above
the set of pieces. (which represents one day of the week only as aforesaid) the
0 numerals on the pieces or cubes represent the whole of such days for twelve
months, or the whole of such days in any given month. Thus if the tablet is
marked Friday and, with the months in the order given above the numerals on the
IP ST

page_text: cubes represent all the Fridays" of the year 1897, or of any particular month of
such year.
The same description applies to the tablet for 'Saturday' and each other tablet
for the other days of the week with the names of the months on the tablet altered
to suit, or the names of the months on each successive tablet put one space nearer
the right hand end of the tablet and the names which were on the end spaces
moved on to or appearing on the left hand spaces, or, if the tablet were a cylinder,
the names being all moved one space for each tablet round the circumference. It
will therefore be seen that the position of the numerals is permanent or constant,
whilst the position of the months is variable for each tablet.
For each succeeding year 1898, 1899, 1900, etc. except leap years, the name of
each tablet is altered one day later (Friday to Saturday, Saturday to Sunday, etc.).
For leap years such as 1896 the tablet is recast and appears as follows:-
When not required for use as a Calendar and for the purpose of Puzzle we trans-
pose two of the cubes or pieces and, by preference, those numbered 6 and 9, and
the solution of the Puzzle is to arrange such pieces by sliding them in the box
into their proper place and order in relation to the other pieces, and keeping the
three plain pieces in the original order, which latter is an essential feature of our
invention.
These pieces and the case or holder containing same and the tablets may be used
for advertising purposes.
If desired the printed matter on the seven tablets may be on one large tablet,
or upon an object having seven facets or divisions, and in this connection more
particularly. we are able to provide a perpetual calendar, by which the date may
be found by knowing the day and month, and the day by knowing the date and
month as aforesaid, and the changes of the months and days be readily effectuated.
The said tablets may be in the form of cubes or movable pieces with the date
aforesaid suitably impressed. Likewise the numerals on the cubes aforesaid may
be arranged to read consecutively in a vertical instead of in a horizontal direction
with the tablets arranged to read vertically.
Dated this 18th day of January 1897

page_text: of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
Our invention consists of a combined date Calendar and Puzzle, or a date
calendar which can be used as a puzzle, or by which the dates of any day of the
week for the whole year, or for any part thereof, can be seen at a glance, or by
which same Calendar, provided the day and month of the year are known, the date
can be ascertained, or if the date and month are known the day of the week can
be found. This said combined Calendar and Puzzle also forms an advertising
medium.
And in order that our said invention may be more readily understood and carried
into practical effect, we have 'hereunto annexed a sheet of drawings, and will now
proceed to describe the same with the, figures and letters of reference marked
thereon.
Fig. 1 represents our improved Puzzle-calendar, as arranged for indicating the
dates of all the Fridays of the year A.D. 1897.
Figs. 2 to 9 illustrate two of the essential parts separately, and Fig. 10 shews a
modification for use in 'leap' year.
In carrying out our invention we employ a number of, by preference, cubical
blocks or pieces (A), and for the purpose of the date Calendar comprising 31
pieces (see Fig. 2), all consecutively numbered from 1 to 31, and for the purpose
of the Puzzle comprising three further pieces (B), but not numbered and left
plain. The numbers of the pieces (A) run laterally, and with the pieces marked (8),
(15) (22) and (29) arranged directly beneath the piece marked (1), produce five
lines of numerals. These 34 pieces (with the addition of another piece for the
purpose of keeping them in a permanent position when used as a Calendar, but
which is removed for the purpose of the Puzzle) are placed in a shallow box or
fram (C), and in, or about, this same box or frame, or an extension thereof or
otherwise in combination with the side cubes, we mount a series of tablets or
plates (D), each of which bears (or is identified with) the name of a day of the week,
and the, current year.
These plates or tablets are also divided by rectangular lines into two rows of
spaces or squares, which in the case of say Friday, and the year A.D. 1897, of the
tablet which bears the name of the first day of the year (except leap year), will
be marked with the name of each month in the manner shewn in Figs. 1 and 3
of the accompanying drawing.
Each other tablet for each of the other days (Saturday, Sunday, Monday, Tues-
day, Wednesday and Thursday) is divided and marked in a similar manner, but
the months, or particulars, on each plate are one division nearer the right-hand
end than the preceding plate, whilst those which were on the extreme right-hand
divisions are moved on to the first divisions at the left-hand end of the tablet, as
shewn in Figs. 3 to 9, or supposing one of the tablets to be a cylinder the whole
of the lettering is moved one division forward in the direction of arrow (z).
Assuming, therefore, that the tablet for Friday 1897' is placed over the
cubes (A), as shewn in Fig. 1, the numerals represent all the Fridays of the
year 1897, or all the Fridays of the month,, or months, of 1897 mentioned in
the divisions, above. Thus the numerals 1, 8, 15, 22, 29 in Fig. 1 represent the dates
of all the Fridays in the months of January and October of the year 1897,-like-
wise the numerals, 2, 9, 16, 23, and 30 represent all the Fridays in the months of
April and July A.D. 1897, and so on for each column and month, and conse
quently the entire set of numerals indicate all the Fridays of the year when read
in conjunction with the names of the months appearing above them.
If any other of the tablets is substituted the same description applies in respect
of the day marked upon, or above it. The marking of the several tablets with the
correct day for each successive year (except leap year) is determined by always
marking the tablet which bears the name of New Years Day in the order shewn
in Figs. 1 and 3,--Thus, for example, the first day of 1898 being on a Saturday,
the
on
Saturday will appear
name
shewn with
the plate now
the
.

page_text: name Friday on it, and so on with each of the other tablets, each one being
marked one day later, ie, from Saturday to Sunday, Sunday to Monday, Monday
to Tuesday, Tuesday to Wednesday, Wednesday to Thursday, Thursday to Friday,
, and Friday to Saturday."
This changing of the names of the days for each year may be effected in various
ways, and, if the tablets are impressed on one piece of material, may be effected
by a sliding tape bearing the names of the days, and when moved readily transpose
.the name from tablet to tablet.
For leap years the tablets are recast and appear as shewn in Fig. 10, and each
succeeding tablet is similarly marked and the names of the months put one division
forward for each successive day, as in the tablets aforesaid.
When not required for use as a Calendar, and for the purpose of a Puzzle, we
transpose two of the cubes or pieces (A), and, by preference, those numbered 6
, and 9, and the solution of the Puzzle is to arrange such pieces, by sliding them in
the box, in their proper place and order in relation to the other pieces, and keeping
the three plain pieces (B) in their original order.
These pieces and the case or holder containing the same and the tablet may be
used for advertising purposes.
If desired the printed matter on the seven tablets may be on one large tablet, or
upon an object having seven facets or divisions, and in this connection we are able
to provide a perpetual calendar, by which the date may be found by knowing the
day and month, and the day by knowing the date and month as aforesaid, and the
changes of the months and days be readily effectuated. In applying our invention
.to a disc or dial form of calendar, we repeat the numerals in seven radial segmental
divisions, one division for each day of the week, and over each division we place
the names of the months in the order and manner given on the separate tablets
.aforesaid, so that with the names of the days and months movable, the calendar is
made perpetual.
'
The said tablets (1) may be in the form of cubes or movable pieces with
the months aforesaid suitably impressed, and the numerals on the cubes may be
arranged to read consecutively in a vertical, instead of in a horizontal, direction,
with the tablets arranged to read vertically.
In lieu of using one set of numerals for each tablet we may employ, or combine,
a separate set with each tablet.
Having thus particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1: The combination of 31 blocks or movable pieces bearing numerals, and three
other blocks without numerals, and arranged as a puzzle and calendar, as set forth.
2: Tablets printed or impressed in the manner shewn in Figs. 3 to 9, or Fig. 10
(and the modified forms to suit the different days), and either upon a series of
plates, or a continuous sheet, or upon a drum, or disc, in combination with
numerals representing the days of the months, as set forth.
Dated this 18th day of October 1897.
