Complete Accepted, 18th Mar., 1887.
We, FRANK SEWILL, Nautical Instrument Maker of 126 Broomielaw, and JULES
BELICARD, Junior, Civil Engineer, of 339 Now City Road, both of Glasgow in the
County of Lanark, Scotland, do hereby declare the nature of this Invention to be as
follows:-
It consists in apparatus for changing the date automatically.
In a suitable case with an open or glazed front for showing the date, we mount a
roller around which is wrapped a length of printed papers or canvas or other suitable
material, with a sufficient number of dates for a year or other period of time printed
thereon.
In the other end of the case we mount another roller which revolves and draws the
length of paper from the first roller either coiling it round itself or rolling the paper
upon a second roller placed beneath, or gripping upon the paper by means of projecting
pins or other suitable means and passing it out of the case by means of a suitable
opening provided for that purpose. To the axle of this second roller is attached a
pinion wheel in which is genred a larger toothed wheel with but a fow toeth on a small
part of its circumference which revolves once in 24 hours or other fixed period, so that
only one revolution of the pinion wheel is affected by one revolution of the larger
toothod wheel, or a ratchet wheel can be used instead of the pinion wheel and operated
by a lever catch or a fleet spring, put on its axle. The necessary motion is given to
the apparatus by means of the works of an ordinary eight day or other long period
clock enclosed in the case or the calender may be mounted in or connected with an
ordinary eight day or other long period clock.

We, FRANK SEWILL, Nautical Instrument Maker of 126 Broomiclaw, and JULES
BELICARD Junr. Civil Engineer, of 339 New City Road, both of Glasgow, in the
County of Lanark, Scotland, 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 :-
It consists in an apparatus for changing the date or other information at fixed
periods automatically. In a suitable case with an open or glazed front for showing
the date, tides, or other information, we mount a roller, around which is wrapped a
length of printed paper or canvas or other suitable material, with a sufficient number
of dates for a year or other period of time suitably marked thereon.
In the other end of the case we mount another roller, which revolves and draws the
length of paper, or other material, from the first roller, either coiling it round itself,
or rolling the paper upon a second roller placed beneath (or in any other suitable
position beside) and in contact with it, or gripping upon the paper by means of
projecting pins, or other suitable means. When the coil of paper has been all wrapped
on the second roller, this roller is taken off and replaced by an empty one and the first
roller which has then become empty is replaced by ono which carries a new coil of
paper, or other material. To keep the first roller from uncoiling itself too rapidly, a
Hat or spiral spring is made to press upon its axle, or other similar appliance is used,
to keep the roller always at a proper tension.
To the axle of the second roller is attached a pinion wheel, in which is geared a
larger toothed wheel, with but a few teeth on a small part of its circumference, or rack
or other similar appliance, which revolves once in 24 hours or other fixed period of
time, so that only one revolution of the pinion wheel is caused by one revolution of the
larger wheel, rack or other similar appliance, the teeth of the larger wheel or rack or
other similar appliance by this means only engaging with the teeth of the pinion wheel
once in 24 hours or other fixed period of time, or a ratchet wheel can be used instead
of the pinion wheel, and operated by a lever catch or a flat spring, put on its axle, or
any other suitable method by means of which a regular intermittent motion may be
obtained, from the regular motion given by the works, or clockwork similar to the
works of an eight day or other long period clock, enclosed in the case, or the calendar
may be mounted in and connected with an ordinary eight day or other long period
clock.
In order that the foregoing may be better understood we send herewith a sheet of
drawings in which is shown a side view of the Apparatus in which a indicates the first
roller, around which is wrapped the strip of paper, or other material, 6 on which is
printed or otherwise marked the dates or other information desired, c indicates the
second roller which is revolved at fixed interval by means of the pinion wheel d into
which gears the wheel segment e revolved by means of works similar to those of a long

period clock, the position of which is indicated by dotted lines ff. This second roller c
revolves a third roller 9 by contact coiling the strip b round it. The third roller g is
mounted upon arms h for convenience of removal when full, and is, as also the roller a
fitted in such a manner as to be readily detached. Any back motion of the roller c is
prevented by the ratchet i held against it by the spring k, but any of the previously
described methods may be used instead of these if found convenient, is the ratchet
and ratchet wheel used in winding up the apparatus.
Having now 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 :-
1st. The apparatus, substantially as described and shown hereinbefore, and in the
accompanying drawing for the purpose set forth.
