PROVISIONAL SPECIFICATION.
Improvements in the Methods of and Apparatus for Using Date and
Time Stamps.
I, BENJAMIN WILLIAM WARWICK, of 134 Highbury Hill, London, N., Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention consists in improved methods of and apparatus for using date
and time stamps such, for example, as are described in my Patent No. 19549 of
the year 1892.
In order that the stamp may not be tampered with hy any unauthorised person,
but at the same time to give free access to the stamping apparatus, 1 secure the
clock carrying the stamp inside a frame. The part of the frame to which the clock
is secured or other portion of the frame is pivoted so as to allow of a slight
movement, which enables the card or other document to be thrust through an
aperture in the frame so as to receive the impression of the stamp. The card to be
stamped is placed on a slide which at the remote end carries the inking pad or
roller. When the slide is drawn out the inking pad is brought so that contact can
be made with the stamp dial.
The minute and hour bands of the stamping dial can be driven so as to revolve
in the same plane in the following way. A crown wheel fixed on the hour axis
gives motion to a pinion. This pinion by means of a carrier supports a cap
carrying the minute hand outside but in the same plane as the hour hand. In a
modification of this arrangement motion is conveyed from the clockwork by a
flexible or jointed conductor or gearing to the stamping dial which is fixed on the
exterior of the case.
I also attach a date and time stamp to the parallel link motion now used for
stamping apparatus, but I make the horizontal frame detachable from the parallel
links so that the apparatus can be easily adjusted. I secure the clock to the link
motion by one or more snaps or springs.
I also fit the clock and dial stamp in a frame so that when not used for stamping
the clock face is approximately vertical, and the clock can be moved forwards and
backwards so as to bring the dial stamp into a horizontal position on the document
to be stamped and in the reverse direction on to an inking pad. The clock is
pivoted to a stirrup which itself is pivoted to the fixed support. The clock is
caused to tumble in its forward and backward movements by an arm attached at
one end to a cam plate or eccentric pin on the clock, and at the other end to the end
of a pin or rod secured to one arm of the frame and moving in a slot in the opposite
arm.
Dated this 14th day of March 1895.

Time Stamps.
I, BENJAMIN WILLIAM WARWICK, of 134 Highbury Hill, London, N., Engineer,
do hereby declare the nature of this invention and in what manuer the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
My invention consists in improved methods of and apparatus for using date
and time stamps, such, for example, as are described in my Patent No. 19549 of
the year 1892.
In order that the stamp may not be tampered with by any unauthorised person,
but at the same time to give free access to the stamping apparatus, I employ the
device shown in Figs. 1 and 2.
Fig. 1 is an external front view of the apparatus ready for use.
Fig. 2 is a sectional side view showing the interior of the same.
In practice A is pivoted at B so as to allow a slight movement. The document
to be stamped is placed on the slide D and inserted through the slot E in the
frame so as to bring the document close to the stamp dial C on the back of the
clock. When the slide is out as shown, the ink pad Ġ comes close to the stamp E.
The front A is fastened by inserting the bolt H in the groove J, and inserting a
padlock through the end. The bolt H allows the frame portion A to move a little
so that the stamp C can be brought right on the document or inking pad as
required. F is a stop or rest on the slide D.
Fig. 3 shows in vertical section a device enabling the minute and hour hands of
a stamping dial to revolve in the same plane.
K is a crown wheel fitted on the central axis L, and driving a pinion M secured
to frame at m, m. The pinion M drives the toothed cap N which carries the minute
hand Q. The cap N rests ou the box frame P. P¹ is the circumference of stamp.
The hour hand R is driven in the way usually employed in time-pieces, the minute
hand and axis as ordinarily used being suppressed.
Fig. 4 is a view showing a device for conveying motion from the clock by a
flexible or jointed conductor to the stamping dial.
X is the flexible conductor attached at one end to the set-hands X' of the
clock X2, and at the other end secured to the axis of the stamp C. Y is a plunger
secured to clock frame by bracket Z. A simple modification of this is shown in
dotted lines, where the flexible conductor X³ is carried to the stamp through a
movable arm, which occupies the position of the bracket Z and is hiuged at Z.
In this case a pad is placed on the clock frame beneath the stamp. In this
modification the stamping dial is at C2 and the pad at C¹.
Figs. 5 and 6 show the clock and dial stamp fixed in a frame, so that, when
not used for stamping, the clock face is in a position convenient for observation.
The clock can be moved so as to bring the dial stamp into a horizontal or other
desired position on the document to be stamped and in the reverse direction on
to an inking pad.
Fig. 5 shows the dial stamp on the inking pad, and Fig. 6 shows it on the
document. The clock is pivoted to a stirrup S, which itself is pivoted to the
fixed support T. The clock is caused to tumble in its forward and backward
movements by an arm U attached at one end to a cam plate or eccentric pin V on
the clock, and at the other end to the end of a pin or rod W secured to one
arm W' of the frame.
Fig. 7 shows a device in which the clock and dial stamp are tilted by a method
already employed in self-inking endorsing stamps. My improvement consists in
checking the movements of the shouldered plunger A' by means of a trigger

page_text: catch B' which is forced on to the plunger by a spring C¹. The lever handle D¹
by forcing up the spring liberates the catch. In this modification the clock face.
can be retained at pleasure in the horizontal or vertical position.
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 method of and apparatus for securing a date and time stamp substantially
as described and shown in Figs. 1 and 2.
2. In date and time stamps a device enabling the minute and hour hands of a
stamping dial to revolve in the same plane substantially as described and shown in
Fig. 3.
3. A date and time stamp operated by a flexible or jointed conductor, substan-
tially as described and shown in Fig. 4.
4. A moveable date and time stamp containing a clock in which the clock face is
retained in a position convenient for observation when not in use, and can be
tilted so as to bring the stamping dial in contact with the document to be
stamped, or an inking pad or roller, substantially as described and shown in
Figs. 5 and 6.
5. In a movable date and time stamp the device for stopping and liberating the
plunger substantially as described and shown in Fig. 7.
