PROVISIONAL SPECIFICATION left by the said William Morgan-Brown
at the Office of the Commissioners of Patents, with his Petition,
on the 21st April 1873.
I, WILLIAM MORGAN-BROWN, of the Firm of Brandon and Morgan-
Brown, Engineers and Patent Agents, of 38; Southampton Buildings,
London, and 13, Rue Gaillon, Paris, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN THE TRANSMISSION OF MOTIVE POWER
and in the AppARATUS FOR THAT PURPOSE," to be as follows:-

page_text: the application of the pressure of liquids, liquids mixed with air or
other gaseous matter and enclosed in tubes of small diameter for the
purpose of, firstly, for communicating movements to great distances to
bells and to telegraphs usually worked by electricity; secondly, to
distribute the time by means of several timekeepers that are made
to work regularly together; thirdly, to communicate fire to mines and
torpedoes, either on land or under water, or at sea without electricity
and by simple metallic wires or tubular wires non-insulated called
aero-hydraulic.
The tubular wires which may be used for submarine lines may be
used without any covering to save expense, and any rupture can be
easily discovered by filling them from the ends with compressed air,
which escaping at the broken part produces on the surface of the water
a considerable bubbling easily seen.
The movement of the fluids enclosed in the conducting tubes or wires
is obtained by pressure from pumps or hydraulic presses worked by
hand, steam, or hydraulic force according to the necessity or convenience
of the power, and the said movements are made visible at each ex-
tremity of the conducting tubes or wires either by signs marked on
bands of paper, as in the Morse telegraph, or on alphabetical dials, or by
means of the impression conveyed in any other suitable manner.
The apparatus used consists, for the first case, in a pump established
at the transmitting end of the tubular wire and a graduated glass scale
at the receiving end, the liquid used being hermetically closed within
the two connected by the tubular wire, whatever its length may be. I
prefer working the pump by means of a handle rotating round a fixed
graduated dial plate and connected with its plunger in any convenient
manner, so that the rotation of this handle in one direction will cause a
depression of the liquid in the pump, whilst rotated in the other direction
it will cause a corresponding elevation of the said liquid. On charging
this apparatus with such an amount of liquid that on the handle being
set at 0 on the circular graduated scale its level on the graduated glass
scale stands also at 0, it follows that the depression of the liquid in the
pump to any figure of the scale attached to the same will cause a corre-
sponding elevation of the liquid in the glass tube, and vice versa.
For the second and third cases I prefer using at one extremity of the
tubular wire a pump, the plunger of which receives a direct rectilinear
motion in order that its action may be repeated more rapidly, and at

page_text: the other extremity of the tubular wire I adapt a small piston which
rising on the depression imparted to the plunger is caused by any
appropriate mechanism either to actuate the pendulum of a time keeper
or to liberate a spring catch, which by its percussion ignites the fuse of
a mine, or torpedo, or such similar exploding agent.
