PROVISIONAL SPECIFICATION.
An Improved Calendar or Date Indicator.
I, CHARLES JOHN LETTS, 3 Royal Exchange, in the County of London,
Manufacturer, do hereby declare the nature of this invention to be as follows :-
--
The object of the present invention is to produce a more sightly and neater date
indicator than those heretofore in common use.
According to my invention, I provide a box or case made of cardboard, pasteboard
or other suitable material and of a convenient or suitable size, and having in the
front wall thereof an opening for a purpose hereinafter explained. I fix to the back
wall of the said box on the inside thereof a spring, or two or more springs. I then
place in the said box an ordinary date block of the kind which display the date in
prominent character and from which a leaf is torn to change the indication each
day or week or other period for which the block has been constructed. The said
block is pressed by the aforementioned spring or springs against the front wall of
the box, and the date is exhibited through the aforementioned opening in said wall.
I sometimes make the box to open in order that access to the date block may be
readily obtained to facilitate the removal of the front leaf as required for changing
the date exhibited.
Dated this 17th day of February 1893.

COMPLETE SPECIFICATION.
An Improved Calendar or Date Indicator.
I, CHARLES JOHN LETTS, 3 Royal Exchange, in the County of London,
Manufacturer, 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 the present invention is to produce a more sightly and neater date
indicator than those heretofore in common use.
According to my invention, I provide a box or case made of metal, wood, card-
board, pasteboard or other suitable material and of a convenient or suitable size,
and having in the front wall thereof an opening for a purpose hereinafter explained.
I fix to the back wall of the said box or to the sides on the inside thereof an elastic
cord, or a spring, or two or more springs. I then place in the said box an ordinary
date-block of the kind or class which display the date in prominent characters and
from which the front leaf is removed to change the indication cach day or week or
other period for which the block bas been constructed. The said block is pressed
by the aforementioned spring or springs against the front wall of the box, and the
date is exhibited through the aforementioned opening in said wall. I sometimes so
make the box that it will open in order that access to the date block may be readily
obtained so that it may be renewed from year to year.
In the accompanying drawing I have shown how my invention may be conveniently
carried into practice.
Figure 1 is a perspective view of a date indicator constructed in accordance with
my invention.
Figure 2 is a section of the same.
A is a box made of metal, wood, cardboard, or other suitable material and having
an opening B in the front wall thereof through which the front leaf of the date-block

page_text: can be seen. The said date-block C may consist of a pack or bundle of loose
leaves or slips arranged in proper sequence. D is a spring suitably secured to the
back wall of the box and arranged to press against the back of the date-block to
maintain the front leaf of said block pressed against the front wall of the box. As
each day or period to which each leaf or slip of the block is appropriated expires,
the front leaf is removed, and the next leaf exposed to view by slightly pressing
down the block and simultaneously withdrawing the expired date slip. It is
obvious that by means of the spring D the block is always maintained tightly
pressed against the front wall of the box until every leaf is used. The date
indicator thus always retains the same appearance, and is very neat. When the
date-block is exhausted, another may be substituted for it, so that it is not necessary
to replace the containing box each time the date-block is changed. To facilitate
the changing of the entire block I may make the back or front wall, or the top,
bottom or one of the sides of the box removable or hinged to the box so that the
box can be readily opened and access bad to the interior.
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 :-
:-
1. A date indicator comprising a box having an opening in the front through
which the date can be seen, a date-block having removable leaves contained in said
box, and means for pressing the said date-block against the front wall of the box,
for the purposes specified.
2. A date indicator constructed substantially as described with reference to the
drawing, and operating as specified.
Dated this 24th day of October 1893.
