Improvements in the Construction of Perpetual Almanacs.
We, ALFRED CHARLES DURANT and FREDERICK WILLIAM HENRY
DURANT, both of Peel Place, Bradford, in the County of York, Insurance
Brokers, 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 :-
This invention relates to certain improvements in movable date almanacs, and
has for its object, the construction of the same in such a manner that, movable
figures of a large size for indicating the days of the month can be utilized on a
comparatively small card or other support, and to thus economise the wall space
occupied by the almanac and afford facilities for seeing the date at a considerable
distance.
In describing our invention in detail, reference is made to the accompanying
drawings, in which
Fig. 1 represents a front elevation of an almanac made according to our
invention.
Fig. 2 is a view of the dating device, and Fig. 3 a modification thereof.
The support or foundation A may be of cardboard or other material, and
ornamented in any suitable manner. The foundation is perforated towards one
side, by preference with two holes B and C, through which the date figures are
seen.
On the opposite side of the foundation A, is a circular disc D, mounted upon a
stud, and operated from the front side by means of a small knob E secured on the
stud. The disc D is provided with figures so placed thereon that, each figure when
brought opposite the opening C is perpendicular, that is, at right angles with the
bottom of the foundation.
Another set of figures are placed upon the cross piece F for indicating the tens,
and which is mounted and operated in the manner as before described. This cross
piece F has portions cut away at G, in order that the full area of the opening C
may be utilized for exposing the figures on the circular disc D, so that, by the
operation of the two, F and D, the date is indicated in a conspicuous manner by
larger figures than can be utilized upon a disc of the same diameter when they are
arranged in any other manner.
A modification of the disc D is shown by Fig. 3, in which case, the figures
thereon are arranged in the same manner as before described, but portions are cut
away from the periphery near to each figure as shown at H. in which case the
figures indicating the tens are placed upon a circular disc J.
By cutting the indents H in the periphery of disc D, in the manner shown by
Fig. 3, the whole area of the opening B. is rendered available for the exposition of
the figures equal in size to those placed upon the disc D and cross piece F shown
by Fig. 2.
It will be easily understood that, the dating device may be utilized for indicating
numbers for other purposes, such as recording the points won in games.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
"
In an almanac the perforation of the foundation A. at B and C. combined with

page_text: the mounting of a disc D. or the like and cross piece F having figures arranged
thereon substantially in the manner as shown and described.
