To defeat any attempt to remove and replace the paper disc I employ a circular
nut of large diameter to confine the disc upon the hoor axis of the clock. I form i
a small perforation in this nut and when the paper disc is in place I mark it with
a pin inserted through this perforation. Similarly before changing the disc I again
insert the point of a pin into the perforation which if the disc has been tampered
with marks it a second time but if not passes through the original perforation.

I JOHN MILLAR of Bethnall House Cambridge Road in the County of Middlesex
Physician 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:―
My tell tale timekeeper consists in a clock of any construction but with a paper
disc suitably marked replacing the hands and revolving say in twelve hours.
This clock is locked up in a box and there is a hole in the door or cover of the
box through which a pencil can be inserted and made to mark on the paper disc.
The clock so locked up is fixed at the station to be visited by the watchman. The
position of the clock in the box can be altered to render the necessary changes of
the paper disc less frequent. To prevent or detect tampering with the apparatus
by opening the box with a false key and then marking the disc in a manner to
deceive. I provide a sheet of transfer paper beneath the disc but separated from it
by an intermediate surface of cardboard or other material with an aperture in it.
The aperture coincides with the hole in the door or cover of the case. The
transfer paper and the separating material are so fixed in the clock as not to
revolve with the disc. When the disc is marked in a legitimate way in addition
to the mark on the face a corresponding mark is produced on the back by the
transfer paper.
To defeat any attempt to remove and replace the paper disc I employ a circular
nut of large diameter to confine the disc upon the hour axis of the clock. I form
a small perforation in this nut and when the paper disc is in place I mark it with
a pin inserted through this perforation. Similarly before changing the disc I again
insert the point of a pin into the perforation which if the disc has been tampered
with marks it a second time but if not passes through the original perforation.
In order that my said invention may be fully understood and readily carried
into effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS,
Figure 1 is a front elevation of the tell tale clock-the door of the case being
open. Figure 2 shows the record disc separately. Figure 3 shows the surface of
cardboard or other material behind the paper disc. Figure 4 shows the transfer
disc. Figure 5 shows a metallic table or surface supporting the preceding parts
and serving to enclose the clock train.
Figure 6 shows a portion of the hour axis of the clock.
a a is the case it has a door and it is provided with a lock. At a¹ is the hole
in the door by which when the case is closed the pencil is inserted for the purpose
of marking the record disc. b is the record disc it is of paper. The hole in the
centre of the record disc through which the hour axis passes is made to receive
the axis loosely so as to increase the difficulty of tampering with the nut and
record disc and readjusting them after movement to their previous position. c is

page_text: a large flat nut d. The record disc b when in place is clipped between the collar o'
and the nut d. d' is the perforation in the nut d for the insertion of a pin point
to mark the record disc so that when set it may not be removed and replaced
without detection. is the surface interposed between the record disc and the
transfer disc. f is the transfer disc it only marks the back of the record disc
when the pencil is legitimately applied to the face that is to say through the
hole a and then the point of the pencil meets the gap el in the surface e. g' g³are
shallow blocks which may be placed in the case beneath the clock to raise it when
the record disc has been already marked so that the record disc may serve for more
than one record and that marks afterwards made may not interfere or be confused
with previous marks. Colored pencils may also be employed to distinguish the
records so that more than one record may be made on the same part of the record
disc without confusion. By employing pencils of three colors to mark the outer
ring of the record disc and raising the clock by the successive use of first one and
then both of the blocks g¹ and g' and marking the inner rings with pencils of two
colors it will be necessary to change the record discs only once a week.
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. A tell tale clock with case a having a hole a¹ for the insertion of a pencil
and record disc b secured upon the hour axis c of the clock train substantially as
and for the purpose described.
2. A tell tale clock with case a, hole a¹, record disc b, hour axis c, perforated
nut dd, surface e, and transfer disc f substantially as and for the purpose
described.
3. A tell tale clock with case a, hole a³, record disc b, hour axis c, and perforated
nut d substantially as and for the purpose described.
