PROVISIONAL SPECIFICATION left by the said Herbert John Haddan at
the Office of the Commissioners of Patents on the 15th March 1883.
HERBERT JOHN HADDAN, of Kensington, Middlesex, "IMPROVEMENTS IN
MECHANISM FOR CONTROLLING AND REGISTERING CLOCKS," a communication to
me from abroad by Anatole Lasmoles, of Chateauroux, France,
This invention has for its objects to obtain security of control, by placing it in
a fixed position, and without the reach of the night watchman, who has only to
move an electric contact piece or switch placed in 'every building visited by him,
also to record the exact time of the visit and how many times the apparatus has
been set in operation, also to provide an electric dial or sheet which indicates the
places visited, and the number of visits.
Also to exercise a control over carrier pigeons, so as to indicate the arrivals
without interfering with the ordinary work of the attendant, And also to
serve as an ordinary clock, while capable of performing the functions described
above.
The construction and operation of the apparatus is as follows: If the electric
contact is established, a pawl is lifted thereby disengaging a counting disc or wheel,
which turns until the said pawl meets another notch of the counting wheel, after
which the pin of a stop-wheel strikes against a face or buffer of the pawl. In
turning, the counting wheel sets in motion a lever by means of suitable projections,
and lifts a movable dial which then strikes a pointed clock-hand, is perforated and
shows the exact time.
The dial is afterwards brought back into its previous position by means of
springs.
At the same time the counting wheel lifts by means of suitable projections
another lever, thereby moving a wheel which carries a pointed clock hand. If then
Prine 71

page_text: the movable dial is lifted, it meets the point of the said hand and is perforated,
after which the hand is placed back by a spring.
At the same time a pin attached to the counting wheel releases a tooth of
the totalizing tooth wheel and causes the pointer which it supports to advance
one division. This pointer shows how many times the apparatus has been in
operation.
An alarm apparatus may be combined with the clock by providing a hammer
placed so as to strike a removable gong.
If used for the control of carrier pigeons the door of the pigeon house is
lifted by the pigeon when entering, thereby coming in contact with the pawl
described above, releasing the wheel and operating the hammer which strikes
the gong.

IN
HERBERT JOHN HADDAN, of Kensington, Middlesex " IMPROVEMENTS
MECHANISM FOR CONTROLLING AND REGISTERING CLOCKS," a communication to
me from abroad by Anatole Lasmoles, of Chateauroux, France
This invention relates to the construction of controlling or registering clocks
applicable as watch mens' time detectors and for similar purposes, and has for its
object to obtain the following advantages:
1. Security of control, by placing the apparatus in a fixed position and out of
reach of the watchman, who has only to press with the finger on a button connected
with an electric contact piece or switch placed for this purpose in every building
to be visited.
2. To record the exact time of the visit.
3. To record how many times the said apparatus has been set in operation.
4. The connection of the apparatus with a dial or board in electric connection
indicating the total of the number of visits and the places visited.
5. The adaptability of the apparatus for the purpose of exercising a control over
carrier pigeons by indicating the arrivals of the pigeons without interfering with
the ordinary occupation of those in charge of the same.
6. The apparatus also serves as an ordinary clock, its working not being affected
by its functions as a controlling apparatus.
In the accompanying drawing which illustrates this invention
Fig. 1 represents a front view of the whole apparatus after the dial has been
removed.
Fig. 2 is a front view of the perforating mechanism without the star-wheel a and
the dial.
Figs 3 and 4 are side views of the apparatus showing the working of the locking
plate g, of the lever e as well as of the perforating hour hand m'.
Fig 5 is a back view showing the arrangement of the going part after the plate
has been removed.
Fig 6 is a side view of the going part.
Fig 7 shows the position of the lever after the same has been released.

v detent of the ratch '.
y counting dial mounted on the arbor of the ratchet wheel x¹.
¹armature serving to discharge the detent l.
2 rod connecting the armature with the detent 1.
The apparatus works as follows:
When electric contact is established two movements take place simultaneously.
1. The spring u' is attracted by the magnet t' whereby the part u" causes the
ratch to move one tooth which causes the counting dial y¹ to advance one
number.
2. At the same time the armature z¹ is attracted by the electro-magnet t¹¹ and
the rod fixed to the armature lifts the detent and consequently discharges
the locking plate which turns till the detent meets another notch k when the
forelock or pin of the wheel g₁ strikes against the projection of the detent 7,
during this turning of the locking plate g one of the projections & comes in contact
with one end of the lever e lifts the same by causing it to oscillate round its axle e¹

page_text: while the other extremity e of the same lever depresses the wheel b as well as the
hand m, the latter while being depressed meets the dial of paper p" which by
means of the pin or tooth m¹¹ is perforated at the time indicated by the clock on
which the apparatus is mounted.
Furthermore one of the pins i of the locking plate g meets the star wheel a and
causes the same to move one tooth in consequence of which the hand o' mounted
on the arbor of the star wheel a is advanced for one number on the dial p¹ and
thus indicates how many times the apparatus has been operated. After the lever e
has caused the movements as above described, it is brought back into its previous
position by means of the spring f which at the same time lifts the wheel band the
hand m. During the whole time the locking plate g turns, the hammer r¹ strikes
against the bell 81; this bell s¹ is adjustable.
The movement of the hammer is a vibrating movement produced by means of
the anchor which discharges but one tooth of the wheel dat a time; in this
manner the apparatus becomes an alarm.
The detent is brought back in its previous position by means of the
spring m.
It is sufficient to establish another electric contact, to reproduce the operations.
as above described.
If the apparatus is used for the control of carrier pigeons the door of the pigeon
house is arranged in such a manner that the pigeon when entering the pigeon
house causes the door to establish the electric contact, the detent discharges the
mechanism, the bell announces the return of the pigeon and the dial p" indicates
the time while the dial p¹ indicates the number of pigeons returned.
.
The motion of the hand m³ may be combined with the dial p¹ without departing
from the nature of the invention.
CLAIM
In combination with an ordinary clock movement an indicating and controlling
apparatus substantially as described and illustrated and for the purposes set
forth.
In witness whereof I the said Herbert John Haddan have hereunto set my
hand and seal this 24th day of September A.D. 1883.
