Year: 1853

page_text: LETTERS PATENT to Jean Pierro Albert Galibert, of Paris, in the
Empire of France, Doctor of Medicine, and of No. 4, Trafalgar
Square, in the County of Middlesex, for the Invention of "AN
IMPROVED DOMESTIC TELEGRAPH."
PROVISIONAL SPECIFICATION left by the said Jean Pierre Albert
Galibert at the Office of the Commissioners of Patents, with his
Petition, on the 10th August 1853.
I, JEAN PIERRE ALBERT GALIBERT, do hereby declare the nature of
the said Invention for "AN IMPROVED DOMESTIC TELEGRAPH to be as
follows:-
This Invention consists in certain new mechanical arrangements and
combinations of parts constituting a cheaper and more simple machine
or apparatus for the above purpose than the arrangements bitherto
employed for a similar purpose. And in order to ascertain the nature
of this Invention more completely reference must be had to the
illustrative Drawing hereunto annexed, and to the numeral figures
and letters of reference marked thereon respectively, as follows:-

Figure 1, exhibits a front elevation of a machine constructed
according to this Invention.
Figure 2, is an elevation of the machine with the front plate
removed.
Figure 3, is an elevation of the back of the front plate.
Figure 4, is a top plan view of the machine.
Figure 5, an elevation of the back of the machine.
At each of these Figures similar letters of reference are employed to
lenote corresponding parts in so far as such parts appear or can be
seen at each of the Figures respectively.
A, A, marks a metal frame, to which is screwed the front plate B,
and back plate C.
The frame A, has holes formed through the upper part thereof
through which pass a series of rods D, D, and there is a cross bar E,
fixed to the frame A, A, through which the lower ends of the rods D,
pass, as shown at Figure 2, said parts, as also the holes in the plate,
being formed square to prevent the rods from turning round. F, F,
mark two lovers, the outer ends whereof are connected together by a
bar G, and the inner ends of said levers are connected to the sides
of the frame A, by screws 1, which are the filera for said levers to
turn upon. The bar G, is formed with holes therein, through which
are passed cords 2, the ends whereof are affixed to the lower ends of
cach of the rods D, and there is another lever H, connected to the
bar G, the fulcrum of said lover being a pin at 8, and to the opposite
end of the lever H, a wire I, is attached, which communicates with the
parts K, L, M, for actuating the hammer N, which strikes the bell O.
It will be scen upon referring to Figures 1, and 2; that each of the rods
D, are formed with pins or projections 4 which take into slots 5,
formed in the front plate B, and there are pieces of metal PP, which
slide in said slots for the purpose of covering and uncovering certain
figures or numbers marked 1, 2, 3, 4, and so on, and there is a sliding
frame Q, placed at the back of the plate B, to which is attached a
lever R, and spring, and wire S, & T, said-spring being employed for

page_text: keeping the frame always up in the position exhibited at Figure 3.
Thus it will be seen that as one or other of the rods D), are pulled
up the plate P, in connection with such said rod will be raised, and
expose to view the number or figures which were previously concealed,
the rod D, being caused to descend by a spring at 5; and supposing
the bell wires from each of the several rooms of a house to be con-
nected to the rods D, D, it will appear evident that the servant will be
able at once to ascertain from which room the hell has been rung, and
in like manner if the bell should be rung from several rooms, as is
frequently the case at hotels, the numbers corresponding to cachi
room will be uncovered, and thereby indicate these particulars rooms 1s
requiring attendance.
Before answering the summons the servant should again cover the
numbers to enable him to ascertain upon his return whether the bell has
been rung from other rooms, and such covering may be effected by
pulling the wire T, by the ring U, by which the bars 6, of the frame Q,
will depress as many of the plates as are up, the spring S, returning
the frame to its original position.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Jean Pierre Albert Galibert in the Great Seal
Patent Office on the 10th February 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, S
JEAN PIERRE ALBERT GALIBERT, of Paris, in the Empire of France,
Doctor of Medicine, and of No. 4, Trafalgar Square, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of August, in the year of
our Lord One thousand eight hundred and fifty-three, in the seven-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Jean Pierre Albert Galibert, Her
special licence that T, the said Jean Pierre Albert Galibert, my execu-
tors, administrators, and assigns, or such others as I, the said Jean

page_text: Pierre Albert Galibert, my exccutors, administrators, and assigns,
should at any time agree with, and no others, from time to time and
at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "Ax IMPROVED DOMESTIC TELEGRAPH," upon
the condition (amongst others) that T, the said Jean Pierre Albert
Galibert, by an instrument in writing under my hand and seal, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Jean Pierre Albert Galibert, do
hereby declare the nature of the said Invention, and in what manner
the same is to be perforined, to be particularly described and ascertained
in and by the following statement thereof (that is to say):
'
My. Invention of an improved domestic telegraph is intended to
supersede the apparatus at present in use for indicating to domestic and
other servants the particular apartment where their presence or atten-
dance is required, and is applicable to hotels, private dwellings, and
other buildings, and is more particularly adapted to be used on board
of steam and other vessels, as it is so arranged and constituted that no
rocking or pitching motion of the vessel, even during the most severe
weather, can possibly derange or alter the relative positions or move-
ments of the various parts.
•
The arrangement of apparatus which I employ for this purpose is as
follows: Upon a dial plate in front of the apparatus a certain number
of letters, numeral figures, or other signs are engraved or otherwise
marked corresponding with the several apartments of the building or
vessel. Each of these letters, numeral figures, or signs are concealed
or hidden from the view of the domestic or other servants by means of
a small sliding plate or shutter when the apparatus is in a quiescent
state. The sliding plates or shutters are each connected by a pin to a
sliding rod furnished with a retaining spring, and to the upper end of
each of these sliding rods is attached a wire or cord communicating

page_text: with one of the apartments of the building or vessel. The lower end
of each of the said sliding rods passes through a bar, which is connected
by means of any ordinary self-adjusting escape movement to the ham-
mer of a bell in such a manner that the raising of any one of the rods
will cause the hammer to strike the bell. I would also observe that
the raising of the rod, caused by pulling the wire in any of the several
apartments, at the same time uncovers or exposes to view its respective
figure, letter, or sign, so as to indicate to the servants from which
particular apartment or apartments the bell has been rung or struck,
even though attendance may be required simultaneously in several
different apartinents. The attendant, after ascertaining the numbers.
letters, or signs that are uncovered, by pulling a wire or cord replaces
all the shutters, in order that if during his or her absence the bell has
been struck the uncovering or exposure of the corresponding letier,
figure, or sign indicates the fact upon his or her return.. The mecha
nical construction and practical working of my Invention will be more
completely ascertained by referring to the illustrative Drawing hereunto
annexed, and to the numeral figures and letters of reference marked
thereon respectively, and corresponding with those in the following
explanation thereof:--

annexed, and to the numeral figures and letters of reference marked
thereon respectively, and corresponding with those in the following
explanation thereof :-
DESCRIPTION OF THE DRAWING.
Figure 1, exhibits an external front elevation of an apparatus con-
structed according to the principles of my Invention; Figure 2, is an
elevation of the apparatus with the front or dial plate removed
Figure 8, is an elevation of the back of the front or dial plate; Figure
4, is a top plan view of the apparatus; Figure 5, is an elevation of the
back plate, shewing more clearly the striking apparatus; and Figure 6,
is a transverse and vertical section taken through about the line A, B,
in Figure 1. At each of these Figures similar letters of reference are
employed to denote corresponding parts of the mechanism, in so far as
such said parts appear or can be seen at each of the Figures respec-
tively. A, A, marks a metal frame, to which the front or dial plate
B, B, and the back plate C, C, are screwed or otherwise attached.
The frame A, A, has holes drilled or otherwise formed through the

page_text: upper part thereof, through which pass a series of sliding rods D, D;
there is also a cross bar E, E, fixed to the frame A, A, through which
the lower ends of the rods D, D, pass (see Figures 2, and 6), the said
parts, as also the holes in the plate or bar E, F, being formed square
in order to prevent the sliding rods D, D, from turning round. F, F,
is a bar furnished with small holes through which the wires G, G,
attached to each of the sliding rods 1), D, pass, a small pin 1, being
inserted into each wire immediately below the bar. The bar F, F,
is supported and capable of swivelling upon pivots in the small levers
HI, H, the said levers being firmly connected together by means of the
bar I, and vibrating upon fulcra 2. On the bar 1, a small lever K, is
fixed, which is attached to the escape lever I, by means of a wire M.
N, N, is the bell; and O, O, is the hammer for striking the same. It
will be seen upon referring to Figures 1, and 2, that each of the sliding
rods D, D, is furnished with a pin or projection 2*, 2*, which takes
into one of the slots 3, 3, formed in the front or dial plate B, B; and
there are small shutters or plates P, P, which slide in the said slots
for the purpose of covering and uncovering certain figures or numbers
marked 1, 2, 3, 4, and so on. Q, Q, is a sliding frame (placed at the
back of the plate B, B), by means of which all the plates or shutters
may be returned to their original respective positions, being actuated
by means of the lever R, and wire S, S. T, T, are helical springs for
returning the said frame Q, Q, into the position shewn at Figure 3, in
the Drawing; and U, U, are similar springs, one attached to each of
the rods D, D, in order to return them to their respective positions
after having been raised.
Supposing each of the rods D, D, to be connected at its upper end to
the respective wire communicating with one of the apartments in such
a manner that when the wire is pulled its corresponding rod will be
raised, it will be evident that the rising of any one of the rods will
uncover its respective number, and at the same time by raising the
bar F, cause the hammer to strike the bell. The spring U, imme-
diately returns the rod D, into its original position, and the spring V
(see Figure 6.) sets the escape lever K, in gear, and at the same time
by raising the wire M, returns. the bar F, into its relative working

page_text: position, so that the instant the bell is struck all the parts return to s
their original working order, except the shutters or plates P, P, which
remain. up, as shewn at numbers 1, 6, and 14, in Figure 1, thereby
indicating those particular apartments as requiring attendance. Before
answering the summons the attendants should again cover the numbers
to enable them to ascertain upon returning whether the bell has been
rung from any other apartments, and such covering may be readily
effected by pulling up the wire S, S, which will cause the cross bars of
the frame Q, Q, to depress as many of the plates as were up, the springs
T, T, returning the said frame Q, Q, into its original position. If the
action of the spring V, should fail to lower the bar F, and set the
escapement in gear, it may readily be ascertained by the shutters
rising without the bell striking, and may be readily remedied without
removing the front plate by pulling down the wire W.
Having thus described the nature and object of my said Invention of
an improved domestic telegraph, together with the manner in which
the same is to be performed, I would remark, in conclusion, that I
claim as my Invention the peculiar construction and arrangement of
mechanism above described, and shewn in the several Figures of the
illustrative Drawing hereunto annexed, or any modification thereof, to
be employed in the manner and for the purposes above more parti-
cularly set forth.
In witness whereof, I, the said Jean Pierre Albert Galibert, have
hereunto set my hand and scal, this Nineteenth day of January,
in the year of our Lord One thousand eight hundred and fifty-
four.
Witness,
