Year: 1842

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
GEORGE HUGHES, of No. 158, Strand, in the County of Middlesex, General
Agent, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Ninth day of June, in the fifth year of Her reign, did, for Herself,
Her heirs and successors, give and grant unto me, the said John George Hughes,
Her especial licence, full power, sole privilege and authority, that I, the said
John George Hughes, my executors, administrators, and assigns, or such others
as I, the said John George Hughes, my executors, administrators, or assigns,
should at any time agree with, and no others, from time to time and at all
times during the term of years therein expressed, should and lawfully might
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, my Invention of "A NEW APPLICATION OF TELEGRAPHIC
SIGNALS, AND THE MODE OF APPLYING THE SAME;" in which said Letters Patent is
contained a proviso, that I, the said George John Hughes, shall cause a
particular description of the nature of my said Invention, and in what manner
the same is to be performed, to be enrolled in Her said Majesty's High Court
of Chancery within six calendar months next and immediately after the date
of the said in part recited Letters Patent, as in and by the same, reference
being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John George Hughes, do hereby declare the nature of my Invention to
consist, first, in the application of telegraphic signals to the transmission of
lomestic orders from one part of a house or building to another; secondly, in
the application of telegraphic signals to the transmission of domestic orders,

page_text: and orders for the general working of vessels, and also orders for the manage-
ment and regulation of the engines on board steam vessels from one part of
the vessel to another; and lastly, in a particular mode of accomplishing the
same without the aid of verbal communication of any kind. And in further
compliance with the said proviso, I, the said John George Hughes, do hereby
describe the manner in which my said Invention is to be performed, by the
following, statement thereof, reference being had to the Drawing annexed,
and to the figures and letters marked thereon, that is to say:-
DESCRIPTION OF THE DRAWING.
First, with reference to that part of my-said Invention which relates to the
application of telegraphic signals to convey domestic orders from any one part
of a house or building to another. Figure 1 represents the manner in which a
communication may be made from one place to another by means of an endless
band composed of catgut, cord, chain, or any other fabric capable of rotation
on pullies, that portion of the Figure marked No. 1 being placed in the
position from whence the communication is to be made, and that portion of
the Figure marked No. 2 in the position to which the communication is to be
conveyed; a, a, a, a, denote two sheaves or pullies of exactly equal diameters,
over which a band or chain b, b, b, b, b, is passed, so that motion being given
to the pully, or sheave a, a, No. 1, by the handle c, it is communicated by
means of the band b to the corresponding sheave at, No. 2, so that the handle c
No. 1, which is fixed upon the axis of the pulley a, a, No. 1, being moved or
caused to rotate thro' a certain portion of the circumference of the dial d, and
made to rest against any of the words or sentences marked thereon, a similar
motion is produced in the pulley a, a, No. 2, thereby moving the index E thro
the same space, and consequently pointing to a similar word or sentence upon
the dial f. The pullies g, g, g, are exhibited to shew the mode in which the
band or bands can be made to traverse angles. On the circumference of the
pulley a, No. 2, are affixed a number of studs or pins h, which, upon motion
being given to the pully, strike the tail of the bell hammer i, and thereby ring
the bell to draw attention to the movement of the index.
Figure 2 represents another method by which intelligence may be con-
veyed. a, a, represents a drum, similar to those used in clocks or timepieces,
containing a coiled spring; b, b, are cranks like those used for bells, and
hung with wire in a similar way; the crank 61 is supposed to be situate at
the station No. 2, where the communication is to be received, and has a
chain passing from it round the drum a, a; the bell crank b is situate at the
station No. 1, from which the communication is to be made, and having a wire

page_text: passing from it to the small ring e; on drawing the ring e down, motion is
given to the crank b and thence thro' any series of cranks to the crank 6 1,
which again, thro' the chain or wire c passing as before described round the
drum a, a, causes it to rotate. The crank 6 1 being drawn back as far as
the stop f, will cause the drum to make one revolution; on the ring e being
drawn down to the stop or peg No. 2, being one-seventh of the stroke of
the cranks 6 and 61, it will thereby cause the drum a and dial plate d to
make one-seventh of a revolution; the space between the stops No. 1 to 7 is
equal to the stroke of the cranks 6 and 61, and bearing a ratio or being
equal to the circumference of the drum a, it is evident that the ring e, being
drawn down thro' one-seventh of the space, it will cause the drum a to make
one-seventh of a revolution. Presuming that it is desired to draw attention by
means of a bell to any of the figures, words, or sentences marked within or
against the spaces 1 to 7 upon the dial at station No. 2 (similar figures,
words, or sentences being written against divisions similarly numbered on
the plate g at station No. 1), it is only necessary to draw the ring e to the
peg placed against the sentence to which it is wished to direct attention, and
the dial plate will rotate in the manner herein-before described until the
corresponding sentence rests opposite the indicator. n. k, k, are two screw
boxes for..adjusting the length of the wires, so as to produce an equal move-
ment at both extremities of the series of cranks.
In Figure 3 à similar arrangement is made use of to produce the same
motion of the dial, but in this Figure the dial is covered with a fixed circular
plate, in which an aperture is cut sufficiently large only to exhibit the
sentence, or communication necessary to be shewn.
Figures 4 and 5 exhibit the mode in which the above-described instru-
ments may be applied to convey intelligence, as herein-before described,
for marine and domestic. purposes. Figure 4 is a transverse section of a
steam vessel; a, a,, represents the paddle boxes, and 6, 6, the spaces occupied
by the engines. The instruments are here employed to convey the com-
mands of the captain, pilot, or other person to the engineer. There is on
eitlier paddle box a machine similar to No. 1 in Figures No. 1 and 2,.so
that upon the handle being "moved against the requisite indication upon
the dial plate, it is comniunicated by the bands d, d, to the instrument e. in
the engine room, which, by the ringing of a bell, as herein-before described,
calls the attention of the engineer to the communication .conveyed. Figure 5
shews a transverse section of a dwelling house, in several rooms of which the
instruments are placed, the communications being forwarded in the same
manner and by the same means as in Figure 4; a and c are instruments

page_text: similar to No. 1, Figure 1; and band d, instruments similar to No. 2,
Figure 1.
Having now described the nature of my Invention, and the manner in which
the same is to be performed, I hereby claim,-
First, the application of telegraphic signals for the transmission of domestic
orders from one part of a dwelling house or other building to another.
Secondly, the application of similar signals for the transmission of orders for
the management of ships or vessels from one part of a ship or vessel to
another, and particularly the orders of the captain or pilot to the engineers of
steam vessels.
And thirdly, the mode of applying such signals to such purposes by means of
corresponding tablets on which corresponding orders are written, one placed at
the spot whence the orders are to emanate, and the other at the spot where
they are to be received, the communication between the two or more tablets
being made by means of cranks or pullies, as shewn in the Drawing, or by any
other suitable connections.
And such my Invention being, to the best of my knowledge and belief,
entirely new and never before used within that part of IIer said Majesty's
United Kingdom of Great Britain and Ireland, Her said Dominion of Wales,
or Town of Berwick-upon-Tweed, I do hereby declare this to be my Specifi-
cation of the same, and that I do verily believe this my said Specification doth
comply in all respects fully and without reserve or disguise with the proviso in
the said herein-before in part recited Letters Patent contained; wherefore I
hereby claim to maintain exclusive right and privilege to my said Invention.
In witness whereof, I, the said John George Hughes, have hereunto set
my hand and seal, the Ninth day of December, One thousand eight
