1 CHARLES LUND, O1 20 Fleet Street, in the City of London, Cutler, do hereby
declare the nature of my said invention to be as follows:-
The object of my invention is to manufacture improved perpetual date indicators,
to act automatically for indicating the month, and the day of the month and week and
other information.
In carrying out my invention I usually construct a suitable outer case or box,
having three openings in front, one opening being for the month, another for the day
of the week, and the third one for the number of the day of the month.
Three small holes are formed in the top of the case, through which throe cylindrical
or other shaped keys project to a short distance above the case. These keys are in
connection with suitable mechanism fitted inside, and, upon pressing one of the keys
with the finger, the mechanism with which it is connected is moved forward one stage
or degree.
Upon the face of, and near the outer circumference of a wheel, or an annular ring
or its equivalent, I place figures to indicate the days of the month. I also form
thereon ratchet teeth or other suitable projections into each one of which a pawl
engages or is thereby raised, as it is caused to rotate in one direction only, in a manner
well understood by mechanics. One of the numbers indicating a day of the month
is always exposed to view in one of the openings before mentioned, the remaining
numbers being out of sight. I also fit a rod and pawl or its equivalent in such a
manner as to be operated upon by one of the keys in connection therewith, and also
to operate upon the ratchet teeth or suitable projections of the wheel or ring; the
result being that when the key is pressed with the finger, the wheel or ring is caused
to rotate to the extent of one of the numbers or dates upon its surface.
The two other keys are caused to actuate rollers in an equivalent manner, such
rollers carrying printed matter consisting of the days of the week, and the months
of the year.
These rollers may, in some cases, be made of small diameter,
and be made to wind or unwind webbing or paper, suitably printed, from or to other

such rollers may be made of sufficient diameter to contain, in longitudinal lines, the
days of the week, and the months of the year, in succession; one roller, in such last
mentioned case, being made to rotate through one seventh and the other one twelfth
of the circumference, with one impulse of the respective keys.
The foregoing description is intended to shew the nature of my invention, but not
to limit the construction of the same, as it will be obvious to practical mechanicians
that the positions of the keys, the axles, and the directions in which the various parts
are made to move, and the number of such parts may be very much varied in character
and detail.

page_text: 1 CHARLES LUND of 25 Fleet Street in the City of London, Cutler, do hereby
declare the nature of my said 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 my invention is to manufacture improved perpetual date indicators,
for indicating the month, and the day of the month, and week, and other information.
In carrying out my invention I usually construct a suitable outer case or box,
having three openings in front, one opening being for the month, another for the day
of the week and the third one for the number of the day of the month.
Three small holes are formed on the top of the case, through which three keys of
any convenient form project to a short distance above the case. These keys are in
connection with suitable mechanism fitted inside, and upon pressing one of the keys
with the finger, the mechanism with which it is connected is moved forward one stage
or degree.
Upon the face of and near the outer circumference of a wheel or an annular ring
or its equivalent, I place figures to indicate the days of the month. I also form
thereon ratchet teeth or other suitable projections into which a pawl or spring engages
and whereby it is caused to rotate in one direction only, in a manner well understood
by mechanics one of the numbers indicating a day of the month is always exposed
to view in one of the openings before mentioned, the remaining numbers being out of
sight. I also fit a rod and pawl or its equivalent in such a manner as to be operated
upon by one of the keys in connection therewith, and also to operate upon the ratchet
teeth or other suitable projections of the wheel or ring; the result being that when the
key is pressed with the finger, the wheel or ring is caused to rotate to the extent of
one of the numbers or dates upon its surface.
The two other keys are caused to actuate rollers in an equivalent manner, such rollers
carrying printed matter consisting of the days of the week, and the months of the
year. These rollers may in some cases, be made of small diameter and be made to
wind or unwind webbing or paper, suitably printed, from or to other rollers, with or
without self winding springs, or equivalent self winding devices; or such rollers may
be made of sufficient diameter to contain, in longitudinal lines, the days of the week,
and the months of the year, in succession; one roller, in such last mentioned case,
being made to rotate through one seventh and the other one twelfth of the circumference,
each with one impulse of the respective keys.
The foregoing description is intended to shew the nature of my invention, but not
to limit the construction of the same as it will be obvious to practical mechanicians
that the positions of the keys, the axles, and the directions in which the various parts
are made to move, and the number of such parts may be very much varied in character
and detail.

page_text: And in order that my said.invention may be particularly described and ascertained
reference is hereby made to the accompanying drawings in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a front view of my invention as usually constructed. Fig. 2 is a plan of
the top. Fig. 3 is a back view of the mechanism and Figs. 4 and 5 arc side views of
Fig. 3. a is the case having openings bede is a plate, which is screwed to the inside
of the caso. f is a box, fixed to the plate e. h are two rollers (shewn by dotted
lines) kkk are three grooved wheels secured to the plate e by screws as shewn. These
wheels act as guides, to and thereby retain the annular plate or ring 31 in position, at the
same time permitting it to rotate. This annular plate has 31 ratchet teeth formed upon
and projecting from its surface. The forward motion of 31 is effected by the bar d,
by means of the spring d' attached thereto, which drives 31 to the extent of one tooth,
when the button D is pressed by the finger. The bar is guided in the square
socket d², in which there is a spiral spring d³, which raises and returns the bar to its
normal position after being depressed. The ring 31 is also fitted with a pawl or click
to prevent backward motion. The front face of 31 has numbers formed thereon from
1 to 31 corresponding to the days of the longest months which are successively
exposed to view through the aperture 6. The button M is attached to the bar m, the
lower end of which works in the square socket m², in which there is a spiral spring m³.
This bar actuates the wheel 12 by means of the spring m¹. The wheel 12 has also a
pawl or click to prevent backward motion. The wheel 12 is fitted to the axle of the
roller which roller carries the names of the twelve months, which are successively
exposed to view through the aperture d. The button W is attached to the bar w, the
lower end of which works in the square socket w, in which there is a spiral spring w
This bar actuates the wheel 7 by means of the spring w¹. The wheel 7 is fitted with
a pawl or click o (Fig. 5) to prevent backward motion. The wheel 7 is fitted to the
axle of the roller 1, which roller carries upon its surface the names of the days of the
week, which are successively exposed to view through the aperture c in the case a.
In the foregoing description I have described one method of carrying out my
invention, but it is obvious that the details may be very much modified and varied to
effect the same object.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is :-
1. The manufacture and use of date indicators, constructed arranged and operating
substantially as herein before described and shown on the drawings.
2. The general construction, combination and arrangement of the several and
respective parts, together forming my invention of an improved date indicator,
substantially as herein before described and shewn on the drawings.
