PROVISIONAL SPECIFICATION.
Improvements in or applicable to Watchmen's or Tell-tale Clocks.
We, ALWYN WALTER STAVELEY, of East View, Regent Road, and ISAAC
HARDY PARSONS, of 21, Narborough Road, both of Leicester, in the County of
Leicester, Electricians, do hereby declare the nature of this invention to be as
follows:-
This invention relates to watchmen's or tell-tale clocks, and consists essentially
in the provision of improved means for marking the record sheets with ink instead
of with pencil, or by perforating the same, as has heretofore generally been the
practice.
According to our invention the cylinder or drum upon which the record sheet is
clipped is mounted upon a horizontal or vertical axis and adapted to move.
synchronously with the hands of the clock in a well known manner.
The markers each consist of a pivoted lever, one end of which serves as the
armature of an electro-magnet, whilst the other end is shaped to bear against the
surface of the record paper, or arranged to move a pin provided for the purpose
and working in bearings, to produce marks thereon when properly inked.
In order to effect the marking of the record sheets we employ an inking ribbon
arranged between the cylinder carrying the record paper and the said pivoted.
levers or pins so that, when the latter are operated by the electro-magnet, they
will press the ribbon against the record sheet and mark it.
It is necessary that the inking ribbon be moved from day to day to expose a
fresh inking surface and we effect this by connecting it in any suitable manner with
the drum carrying the record sheet, so that when this drum is moved to allow a
fresh sheet to be put on the act of moving the drum will operate or move forward
the inking ribbon, or this movement of the inking ribbon may be effected by the
opening of the door of the apparatus.

Improvements in or applicable to Watchmen's or Tell-tale Clocks.
We, ALWYN WALTER STAVELEY, of East View, Regent Road, and ISAAC
HARDY PARSONS, of 21 Narborough Road, both of Leicester, in the County of
Leicester, Electricians, do hereby declare the nature of this invention and in
wbat manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to watchmen's or tell-tale clocks, and consists essentially
in the provision of improved means for marking the record sheets with ink, instead
of with pencil or by perforating the same as has heretofore generally been the
practice

page_text: According to our invention the cylinder or drum upon which the record sheet is
clipped, is mounted upon a vertical axis and adapted to move synchronously with
the hands of the clock in a well known manner.
The markers are each arranged in connection with one end of a pivoted lever
the other end of which serves as the armature of an electro-magnet.
In order to effect the marking of the record shects we employ an inking ribbou
arranged between the cylinder carrying the record paper and the said pivoted
levers or pins so that, when the latter are operated by the electro-magnet, they
will press the ribbon against the record sheet and mark it.
To enable our invention to be fully understood we will describe the same by.
reference to the accompanying drawings, in which :-
Figure 1 is a sectional front elevation of our improved tell-tale apparatus; and,
Figure 2 is a side elevation of the same :
Figure 3 is a face view of the marking mechanism :
Figure 4 is an underside view of the same; and,
Figure 5 is a side view looking in the direction of the arrow, Figure 3:
Figure 6 is a view of one of the bearings for the drum carrying the record.
sheet :
Figures 3 to 6 are drawn to a larger scale than Figures 1 and 2.
a is the frame of the clock movement, and 6 is the cylinder or drum carrying the
record paper the spindle of which is mounted in bearings e and d, the said cylinder
as shewn in the drawings being arranged with a vertical axis and driven from the
clock movement through the medium of the shaft e and the gear wheels f and g so
that it will make one rotation in twelve hours.
is
h, are the markers which are in the form of pins sliding in a suitable frame i,
and j, j are the pivoted levers for operating the same, each of which levers engages
at one end with one of the pins h and at the other end is formed as the armature of
an electro-magnet k whereby, when the armature is attracted by the magnet, the
pin will be brought into contact with the surface of the cylinder b in a manner
which will be readily understood by reference to Figure 4 of the drawings.
the inking ribbon which is carried upon rollers or bobbins m, m and passes between
the ends of the markers h and the drum b in such a manner that when either of the
said pins is moved in the manner hereinbefore described an impression will be
produced upon the record paper. In practice we prefer to arrange the inking
ribbon at an angle to the axis of the cylinder b, as shewn for instance in Figure 1,
so that a very slight movement of the said ribbon will serve to bring an entirely
fresh surface opposite to the pins .
C
It is advisable to move the ink ribbon from day to day to expose a fresh surface
and we provide that the removal of the drum, which takes place when a fresh
record sheet is being applied, shall ensure this and advantageously by the following
means, that is to say, we arrange the lower bearing e for the spindle of the drum on
pivots, and we arrange the upper bearing d in the form of spring-jaws as clearly
shewn in Figure 6. In removing the drum the spindle is pulled out from between
the spring-jaws which open and at the same time the bearing is oscillated upon its
pivots. To the bearing c is fixed a pawl n engaging with a ratchet wheel o
connected by suitable gear wheels with the shaft of one of the inking rollers or
bobbins as will be clearly understood by reference to Figure 2, whereby as the
said bearing c is oscillated the ratchet wheel o and consequently the inking roller
or bobbin will be moved a sufficient distance to bring a fresh surface of the inking
ribbon opposite to the markers h. When the bottom bobbin is full the positions of
the bobbins can be reversed so that the ribbon will then be wound onto the empty
bobbin.
Although we have described our apparatus with the drum having its axis
arranged vertically, it may be arranged horizontally and furthermore the levers by
means of which the markers are operated may have their free ends suitably shaped
to form the markers themselves.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A watchman's or tell-tale clock wherein a series of electrically operated
markers is adapted to produce impressions upon a record sheet carried upon a drum
through the medium of an inking ribbon, substantially as described.
2. In a watchman's or tell-tale clock wherein the impressions are produced upon
the record sheet through the medium of an inking ribbon, means whereby the
removal of the record paper carrying drum to change the record paper is utilized
for moving the inking ribbon, substantially as described.
3. In a watchman's or tell-tale clock wherein the marks upon the record sheet
are produced through the medium of an inking ribbon, arranging the said inking
ribbon diagonally or at an angle to the axis of the record paper carrying drum,
substantially as described.
4. The manufacture and use of the improved watchman's or tell-tale clock.
herein before described and illustrated in the accompanying drawings.
