PROVISIONAL SPECIFICATION.
An Improved Telegraphic Apparatus for Transmitting Domestic
Orders or other Signals.
We LOUIS BOUDET, Pharmacist, and PIERRE LACOMBE, Mechanician, both
of Fumel in the Republic of France do hereby declare the nature of this invention
to be as follows:-
This invention consists in an electric telegraphic apparatus which may be fitted
and used for transmitting certain prearranged signals and is especially suitable for
transmitting domestic or similar orders especially those for refresliments or articles
desired by the consumer or person ordering same and may for such purposes be
advantageously fitted in hotels, restaurants, theaters clubs, cafés, private house,
institutions and other places.
The apparatus is composed of two electrically connected pieces of apparatus namely
a transmitter and a receiver. Each of these is provided with a dial or dials having
spaces into which cards or the like may be placed bearing any desired words, such
as the names of articles likely to be required or ordered in the particular place
where the apparatus is fitted. These names are the saine and are similarly arranged
on both dials. Upon a smaller circle on each dial are other indications for instance
of the amount of the article to be furnished of which the name is indicated by the
aforesaid cards in the outer circle. The transmitter may also be provided with an
indicator for showing that the order has been received and is understood. The
receiver may bear other indicating devices to show also from where the order
emanates and in such case the same receiver may be placed in electric connection
with several transmitters in different rooms or places.
The indications are given by means of pointers moved by toothed wheels
operated by or permitted to move by anchor escapement or similar devices and in
the case of the transmitter the. indications cause the passage of electric currents
which produce equivalent effects in the receiver so that the movement of the
indicators on the receiver is the same as that of those on the transmitter.
To indicate on the receiver the locality of the transmitter from which the order
arrives the former may be provided with electro magnets at different levels each
excited by a corresponding transmitter so as to move an indicator to the same
level, which thus differs for each transmitter, whereby the indication of the locality
of the transmitter may be easily provided for.

> An Improved Telegraphic Apparatus for Transmitting* Domestic
.Orders or other Signals.
We LOUIS BOUDET, Pharmacist and PIERRE LACOMBE Mechanician, both
of Fumel in the Republic of France 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 :-
:-
This invention consists in an electric telegraphic apparatus which may be fitted

page_text: and used for transmitting certain pre-arranged signals and is especially suitable for
transmitting domestic or similar orders especially those for refreshments or articles
desired by the consumer or person ordering same and may for such purposes be
advantageously fitted in hotels restaurants, theatres, clubs, cafés, private houses,
institutions and other places.
The apparatus is composed of two electrically connected pieces of apparatus,
namely a transmitter and a receiver. Each of these is provided with a dial or
dials having spaces into which cards or the like may be placed bearing any desired
words, such as the names of articles likely to be required or ordered in the
particular place where the apparatus fitted. These names are the same and are
similarly arranged on both dials. Upon a smaller circle on each dial are other
indications for instance of the amount of the article to be furnished of which the
name is indicated by the aforesaid cards in the outer circle. The transmitter may
also be provided with an indicator for showing that the order has been received and
is understood. The receiver may bear other indicating devices to show also from
where the order emanates and in such case the same receiver may be placed in
electric connection with several transmitters in different rooms or places.
The indications are given by means of pointers moved by toothed wheels
operated by or permitted to move by anchor escapement or similar devices and in
the case of the transmitter the indications cause the passage of electric currents
which produce equivalent effects in the receiver so that the movement of the
indicators on the receiver is the same as that of those on the transmitter.
To indicate on the receiver the locality of the transmitter from which the order
arrives the former may be provided with electro magnets at different levels each
excited by a corresponding transmitter so as to move an indicator to the same level,
which thus differs for each transmitter, whereby the indication of the locality of
the transmitter may be easily provided for.

showing the two electro-magnets in the centre.
Fig. 15, represents in elevation and in plan mechanism giving the indications
from the place where the orders are given.
In Figs. 1, 2, 3 and 4 the apparatus consists of a dial plate A fastened at a
certain distance from a plate B by means of long screws and a metallic frame a.
Said dial plate is provided with an indefinite number of cavities in which
labels may be introduced and held in place by flat springs 2. These labels bear
any inscription according to the desired purpose.

page_text: On a smaller concentric circle an equal number of Roman or other figures is
arranged, while the needles or hands A', A' which are manipulated by hand with
the aid of the pins a', a² thereon, indicate the desired article of consumption or
the like, of which A¹ gives the designation, A' the desired quantity. Along near the
periphery of said dial plate are also numerals which may be used as conventional
signs for designating, in a café or restaurant for instance, the number of tables or
the like.
From Fig. 2, showing the mechanism underneath the dial plate, between the
latter and the plate B, the operation and transmission of contacts and consequently
of the orders given, will be understood.
For the sake of a clearer understanding of the description we assume the hand
or needle A¹ to be keyed to a tube spindle c, and A2 to the end of the central
spindle c', traversing the former, a similar arrangement applies to the two hands or
needles of the receiving dial plate which is in all its details similar to the transmitter
and which we therefore considered useless to show in the drawings. The only
difference lies in the adaptation of a contact push a represented in dotted lines in
Fig. 1 and shown in its full features in Fig. 6. the object of which is to indicate to
the sender that his order has been received and understood.
The
By turning one of the hands or needles from the left to the right in the direction
of the arrow in Fig. 1, for instance the hand A', a toothed wheel C, keyed on to
the tube spindle c, follows that movement, this wheel being provided with 24 teeth;
each time that one of these teeth is in contact with the finger d fixed on to a
vertical plate that is supported in a suitable manner at d², it establishes an
electric current. The other hand or needle A2 acts with its spindle c¹, upon a
wheel Chaving 12 teeth, thus corresponding with the numerals of the dial
plate A which teeth are brought in contact with a finger e of a plate e'.
currents, which are regulated by the teeth of the wheels, are in an exact manner
reproduced on the receiver, passing through the rods which are adjustable
lengthwise, into the extremity f¹ of the conducting plates g, g', the current from
the plate g passing through the electro magnet D ou the pivot D', and the current
from plate g directly to the receiver. The electro-magnet D is combined with
two magnetic standards E, E', one E of which is arranged in front of one of the
coils and the other E' behind, in order to allow the electromagnet to vibrate about
one half turn around its pivot D¹ that is surmounted by a disk F, the latter bearing
an inscription to the effect that the order has been received. This signal is only
visible when the circuit has been closed by means of the contact that is arranged
at some point of the receiver; but at its deadpoint the disk remains in a position
showing to blank side, as illustrated in Fig. 2.
The current is supplied by a battery placed in a box as represented in Fig. 5,
the positive current running through the conducting plate d³ and the other parts
of the transmitter to the conductor 2, from there to the contact a of the receiver
and thence to the battery. The current also passes to the wheels C, C¹ and the
electro magnets of the disk F, they are directed to the electromagnets G, G¹, of
the receiver (Fig. 6) and the two indicators arranged behind the openings m.
The receiving apparatus comprises as above mentioned, a dial plate A³, similar
to the dial A, and supported in the same manner by a board B to which it is
secured by screws; further, a frame a' the hands or needles A+, A' being without
handles as they are moved electrically, the positive current being supplied from
the transmitter and the negative current directly from the battery (Fig. 6).
The positive and negative currents running through the conducting plates j
and from there to the electro magnets G, G¹, each actuate a lever H, H
respectively, which are movably keyed each to the base of a fork H². H³, the latter
having at their extremities pins i. The lever H of the fork H2 acts upon a
ratchet wheel I with 24 teeth, and the latter corresponds with the wheel C of the
transmitter; the lever H₁ of the fork H³ actuates the ratchet wheel I' with
12 teeth corresponding with the wheel C¹ of the transmitter. The regulation of
the course of oscillation of the forks H2, H3 and of the levers H, H', is effected

page_text: by the springs h which are secured on to the latter, their flexibility being regulated
or determined by the screws h'.
This first arrangement having been described it is easy to comprehend the
working of the apparatus which is to a certain extent nothing but two combined
wheel works, which instead of a direct engagement, are actuated by electric
currents the first part of them (transmitter) being manipulated by hand and the
second (receiver) acted upon electrically by the intervention of forks with pins
operating the ratchet wheel.
The receiver is at its upper end provided with a bell work J which is inserted
in a circuit supplied through a conducting plate 1 that is fastened to one of the
above-mentioned rods j, and this bell work sounds when the hande are set in motion.
The boards B of the transmitter and B₁ of the receiver are suspended in
convenient places by means of eyes or loops K.
Figs. 10 to 15 represent a multiple receiver actuated by two transmitters in
different localities. This arrangement is shown as an example for an extension,
or the mechanism could he made so as to combine one receiver with 3, 4, or more
transmitters.
The dial plate of the multiple receiver as shown in Fig. 10 is fitted along its
circumference with 24 separate cavities which differ in shape only from those
described above, and in these spaces are written the articles of consumption in the
same order as those on the transmitters in two different rooms, No. 1 and No. 2.
The larger hand K indicates the kind of article wanted in the room No. 1, the
smaller hand K' those wanted in room No. 2. On the central space of this plate
there are two small dial plates with 12 numerals each, the one L of which gives
the number corresponding with the transmitter of room No. 1 while the other L'
serving the same purpose corresponds with the transmitter of room No. 2. In two
corners of the plate openings m are arranged for the purpose above described.
The arrangement of the two hands K and K is the same as that above described,
one of them turning with a central axle n the other with a tubular shaft n', and
each being provided with a ratchet wheel o with 24 teeth corresponding to the
24 cavities of the transmitters. Each of these ratchet wheels is actuated by a
swinging fork P with pins px, the fulcrum being at ².
g"
The hands u of the small dial plates L, L', are also actuated each by a ratchet
wheel with 12 teeth, which is moved by a fork with pins 2, these forks pivoted
at the points s. The oscillating movement of these forks is effected by the contacts.
of the toothed wheels C, C', of the transmitters, these contacts being separately
repeated in the 4 electro magnets M. The movement of the forks is regulated by
springs t, which are secured to oscillating bars t', the latter being kept in place by
threaded screws t².
Fig. 15 represents in elevation and in plan an indicating device for rooms No. 1
or No. 2 where the order is given, and this device consists of a small board N
divided in two parts. The upper division is coloured and arranged in front of
one of the windows or openings m, in the dial plate of the receiver, the other
lower division bears the designation of the locality from where the order originates
be this room No. 1 or any other designation. This plate or board is at its upper
end fastened on to the armature v of an electro-magnet this armature pivoting
at the pivot on a vertical support v³. This little apparatus is inserted into the
electric circuit and actuated so as to present through the opening m, the designation
marked on the lower division of the board N; its return to its initial position
taking place upon a pressure on the contact described above, the object of which
is to cause the turning of the disk F of the transmitting board which bears an
inscription denoting that the command is received.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :
1. A telegraphic apparatus comprising a transmitter and a receiver, the

page_text: transmitter comprising a dial plate provided around its circumference with
openings for reception of designations of various articles, and having on a smaller
concentric circle numerals which designate the quantities thereof, two indicators
moved by hand for establishing circuits through toothed wheels adapted to
establish and interrupt successively the currents directed toward the receiver, the
latter having two electro magnets which actuate two oscillating levers united to
two forks governing two ratchet wheels; one of these wheels corresponding to the
designation of the objects etc., the other, of the quantities.
2. The combination with the aforesaid receiver of the bell work for notifying
the order, and the contact push adapted to cause a half revolution of a signal disk
in the transmitter.
3. The construction of a multiple receiver having cavities as described, and two
or more small dial plates, which indicate the quantities by means of hands that are
rotated about axes provided with ratchet wheels, in connection with forks operated
as described.
4. The construction in the said multiple receiver of two or more window
openings, behind which appears or disappears the designation of the locality from
where the orders are given; this result being obtained by use of an electro
magnet with one of its drums on a higher horizontal plane, the pivoted armature
of which magnet supports a board with the designation of the corresponding
locality.
