page_text: 1. PETER MCGREGOR of 5, John Dalton Street Manchester in the County of
Lancaster, Mechanical Engineer and Patent Agent, do hereby declare the nature of
this invention to be as follows:-
The object of this invention is to give additional security against tampering with
the Clock, and an improved mode of marking by the watchinan the time or hour of
his visit.
The works of an ordinary watch or time-piece are used, and to the axle of which-
instead of the usual hour finger-is fixed a disc made of tin or other suitable material,
which carries round with it a paper dial with the hours marked on it, and upon
which can be stamped, signs indicating the time or hour, and the number of times, the
watchman did so.
The clock work is fixed in a tin case, but the disc revolves outside the case-This
case with the disc outside of it, is placed in another case-the space betwixt the two
cases being filled with asbestos felting.-The front of this outside case is hinged as a
door or lid with a lock on it, which locks itself when the lid is closed, and it can then
be only opened with a key.-This outside case when the lid is closed covers the whole
of the clock and the disc with the paper dial-The tin dise with the paper dial on
front of it is fixed to the axle of the clock work by a screw with a flange sufficiently
large to keep the paper dial flat against the disc. A pointer is attached to the
inside case immediately below the dial, to which the dial must be set according to
the time chosen to be marked, and this pointer indicates the time on the paper dial as
the disc revolves.
On the lid of the outer case is attached in a tin bush, a spring stamp with an
ink receptacle on it, which when pressed forward makes a mark on the paper dial-
the handle of the stamp working in the tin bush projects outside of the lid, so that it
can be acted upon by the watchman.
To secure that the lock on the lid of the outside case cannot be tampered with, a
slide is inserted betwixt the lock and the lid with an opening in it to admit of the key

page_text: to the lock, a slip of paper is inserted along with the slide which covers the opening
for the key, so the key cannot be inserted into the lock, without piercing the slip of
paper which can easily be detected when the dial is to be inspected. The slip of
paper may be furnished with special marks, or made of certain sizes, to. prevent its
being easily changed at will.
The whole clock enclosed in its two cases is fixed in a wood box with a lid on it-
the space betwixt the tin case and the wood box, being filled up by asbestos packing
or felting The lid of the wood box is also fastened by a similar lock to that
on the outside tin case, there being a hole provided in the lid, leading to the
stamp handle which may be reached by the watchman, with a peg, nail, or other
suitable instrument.
The clock to be walled in and fixed in any convenient way.

1, PETER MCGREGOR of 5 John Dalton Street, Manchester in the County of
Lancaster, Mechanical Engineer and Patent Agent 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 :-
The object of this invention is to give additional security against tampering with
the clock, and an improved mode of marking by the watchman the time or hour of
bis visit.
The works of an ordinary watch or time piece are used, to the axle of which,
instead of the usual hour finger, is fixed a disc made of tin or other suitable
material which carries round with it a paper dial with the hours marked on it, and
on which can be stamped signs indicating the time or hour, and the number of times,
the watchman did so.
The clockwork is enclosed, and works in a case or framing as usual, and this
case or framing is enclosed in another case, made of tin or other suitable material
with the disc and paper dial outside this case. The whole is then enclosed in a wood
box which can be easily inserted. into a wall and the space betwixt the clockwork
case or framing, and the tin caso, and the space betwixt the tin case and the wood
box, may be filled with asbestos packing or felting to protect the works from the
influence of heat and cold.
In the accompanying sheet of drawings the same letters refer to similar parts
as shewn in the different figures-Figure 1, represents a side view of the wood
box in section, shewing in outline the clock work, and tin cases, as fixed in the
wood box, and the works in their position-Figure 2, represents a front view of
the clock with the lid of the wood box completely open, and the lid of the tin case
partly open.
a is the clock work, 6 the case or framing to which it is attached in the usual
manner, c is a tin case to which the clockwork case or framing 6 is attached, d is the
This
tin or copper disc, and e the paper dial, both of which work outside the case c.
case has a hinged lid which has a lock g on it, which locks itself in closing and the
lid when closed, completely covers up the disc and dial, which cannot be got to except
by opening the lid with a key.
The disc d is made fast to the end of the axle h of the clockwork and the paper
dial e is attached to the disc by the hand screw i screwed into the axle h
the screw has a flange j on it made sufficiently large to keep the paper dial flat
against the disc.
A pointer k, is attached to the case c immediately below the dial, to which the dial
must be set according to the time chosen to be marked, and this indicates the time on
the paper dial, as the disc revolves.
A short wire or pointer fixed on the edge of the disc serves to facilitate the
setting of the dial by placing the figure of the dial corresponding with the hour of the
day in a line with the pin or pointer 1 and in setting the clock the disc to be turned
until the two pointers meet each other as shewn in Fig. 2.

page_text: On the lid of the case c is attached by soldering or any other convenient manner,
the ordinary or well known self-inking pocket, or desk spring stamp m, (see Fig. 3)
the handle of which works freely in the bush or tube n attached to the lid, and when
pressed forward, makes a mark on the paper dial, and thus indicates the time or hour,
and the number of times, thus acted upon by the watchman.
To provide against any unobserved opening of the lid f, a slide o is inserted
betwixt the lock and the lid with the opening p (shown at Fig. 4) in it to admit the
key to the lock, this slide is made with a slit q in it, shewn at Fig. 5, into which is
inserted a slip of paper covering the opening p for the key-the slide with the slip
of paper in it is inserted behind the lock before closing the lid and consequently
a key cannot be inserted into the lock without piercing the slip of paper which can
easily be detected when the dial is to be examined-The slip of paper may be
furnished with special mářks or made certain shapes, or sizes, to prevent its being
easily changed at will.

1. The whole clock in its cases is fixed in the wood box with the lids on it, which is
fastened by the lock t similar to the lock on the lid of the, tin case, the hole in the
lid leading to the stamp handle, which may be reached by the watchman-when the
lid is closed and locked, with a peg, nail or other suitable instrument.

"
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
;
ist. The general arrangement of the clock in the cases and box whereby it can be
easily inserted in a wall, as described and set forth in the drawings.
2nd. In recording the control signs by means of a spring stamp as described and
set forth in the drawings.
3rd. In the arrangement against any unobserved opening by means of placing a
slip of paper before the key-hole of the lock as described and set forth in the
drawings.
