PROVISIONAL SPECIFICATION.
An Improved Combined Perpetual Calendar and Paper Weight.
We, ALFRED WATSON of No. 8 First Avenue, Bush Hill Park, Enfield, in the
County of Middlesex, Electrical Engineer, and ROBERT JOSEPH HOOPER-RASTRICK
of No. 30 Lavender Gardens, Lavender Hill, Wandsworth, in the County of Surrey,
Gentleman, do hereby declare the nature of this invention to be as follows:-
Our invention has reference to what are known as Perpetual Calendars, wherein,
by the movement of one or more parts, the day of the week may be found for any
given day of a month and year. The disadvantage of those hitherto produced is, that
they are devised for suspending against a wall, not always readily available without
the inconvenience of having to rise from ones' seat. To obviate this, we mount upon
a weighted base or stand, ornamental or otherwise as may be desired, three discs of
any suitable material, supported between two uprights, the two end discs being fixed
or loose as may be desired. Upon the periphery of preferably the right-hand disc are
marked the names of the months; upon the centre disc, which is always movable, are
the days of the week and the index letters; and upon the left hand disc are the days
of the month. The years are, with the index letters, arranged upon the stand,
supports or other convenient part of the device. Provision is made for securing the
disc or discs in the position desired.
In using the appliance, if it is desired to ascertain the day of the week for any day
of the month in any year, find the index letter for that year, then turn the centre disc
until the index letter marked thereon corresponds with the month on the right hand
disc, the day of the week will then be found in a position corresponding with the day
of the month shown on the left hand disc.
The device above described, whilst eminently useful as a paper weight, is, as a
caleudar always present when it is desired to ascertain and fix any given date.

COMPLETE SPECIFICATION.
An Improved Combined Perpetual Calendar and Paper Weight.
We, ALFRED WATSON of No. 8 First Avenue, Bush Hill Park, Enfield, in the
County of Middlesex, Engineer, and ROBERT JOSEPH HOOPER-RASTRICK of
No. 30 Lavender Gardens, Lavender Hill, Wandsworth, in the County of Surrey,
Gentleman, 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 :-
The object of our invention is to obviate the disadvantages obtaining with what are
known as Perpetual Calendars which ordinarily are printed upon a sheet of paper or
board and devised for suspension upon a wall, necessitating rising from the seat to
make a reference, thus diverting attention from the subject matter in hand, or, in the
event of its being placed upon the table or desk, the calendar may become overlaid by
other papers, necessitating a search and in all probability causing the thread of
thought to be lost. We overcome these disadvantages by combining a Perpetual
Calendar of novel form with a Paper Weight in the manner hereinafter described.
In the accompanying sheet of drawings illustrative of our invention Figure 1
represents one form of the device having one central movable disc, and Figure 4 is a
plan of same showing the arrangement of the days of the week, months and index
letters. Figure 2 is another form in which there are three movable discs, and
CD 37

page_text: Figure 3 is an end view of same. Figures 5, 6 and 7 illustrate some forms of catches
for holding the discs in any desired position.
In accordance with our invention we mount upon a weighted base or stand A,
ornamental or plain, three discs a, b, c, supported between two standards or
uprights B B¹, the discs a c being fixed to or forming part of said uprights as in
Figure 1, or capable of rotary movement as shown in Figure 2. The centre disc b is,
under all circumstances movable. Upon the periphery of preferably the right disc c
are marked the names of the months. Upon the centre disc b are the days of the
week and the index letters, and upon the left hand disc are the days of the month.
The years are arranged upon the stand, supports or other convenient part of the
device. Said centre disc b is preferably rotated by means of a thumb nut C secured
to a shaft or spindle which, moving freely within the tubes upon which the discs a
and c are mounted, holds the disc 6 firmly. To the free end of said spindle is adapted
a disc or plate D Figures 5, 6, 7 having upon its face or periphery a number of
depressions d, notches e or denticulations corresponding to the number of index
letters and days of the week and month, into which depressions, notches or denticu-
lations is pressed, by a spring g, a button, point or equivalent h to hold the disc D in
any position.
In using the appliance, if it is desired to ascertain the day of the week for any day
of the month in any year, find the index letter for the year, then turn the centre
disc b until the index letter marked thereon corresponds with the month upon the
right hand disc e, the day of the week will then be found in a position corresponding
with the day of the month shown on the left hand disc a.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
First The combination with a Paper Weight of a Perpetual Calendar substantially
as herein described and shown in the accompanying drawings.
Second-The mode of and means employed for locking or holding the centre
disc of the Calendar in any desired position substantially as set forth.
Dated this 3rd day of February 1890.
