the Commissioners of Patents, with his Petition, on the 22nd May
1873. A communication from Mr. Fred. Honigmann, Director of
the Königshütte, residing at Aix-la-Chapelle.
I, FRANZ WIRTH, of the Firm of Wirth & Co., Patent Agency,
residing at Frankfort m (Germany), do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN THE CONSTRUCTION AND APPLI-
CATION OF ROPES, RODS, OR CHAINS TO BE EMPLOYED FOR TRANSMITTING MOTION TO
THE PLUNGERS OF PUMPS, OR FOR DRIVING PURPOSES UNDERGROUND, TOGETHER WITH
CERTAIN IMPROVEMENTS IN THE PLUNGERS OF THE PUMPS FORMING CONNECTION
THEREWITH," (a communication from Mr. Fred. Honigmann, Director
of the Königshüttë, a person resident at Aix-la-Chapelle), to be as
follows:-
The Invention is designed for the purpose of giving stability to ropes,
rods, or chains employed for transmitting motion from an engine or
other motive power machine to pumps or apparatus placed in sub-
terranean passages underground, so that the communication with such

page_text: pumps or apparatus down the shaft or entrance to the mines in which
they are placed may be sufficiently rigid for the purposes required.
According to the improved plan adopted when giving motion to the
plungers of pumps, the rope, rod, or chain is passed down the shaft
alongside the discharge pipe of the pump, recesses being formed in the
flanges of such pipe, so that the rope, rod, or chain may lie near to the
same, one end of which is connected to the plunger or plungers of the
pump or pumps, and its opposite end to a moveable cross head at a point
projecting from the pit shaft, and which is independent from the same.
The upward rise of the cross head gives to the plungers of the pump to
which the rope is connected their full lift or rise, the rope during the
downward stroke of the same being effected through the stability given
to the rope by its connection with the pipes.
The plunger of the pump or pumps is provided with an air space
over the top clack without taking extra space for the same in the 1
plunger; thus the top clack when lifting is closed, so that no water
during this motion is raised, the downward motion alone effecting the
expulsion of the water.
The former arrangement is the description of the means I employ in
order to give to the rope an alternate lift to the plunger when in con- 2
nection with the discharge pipe of the pumps, the stability to such rope
in the downward stroke being effected by means of the pipe itself.
According to a second arrangement I adopt in order to give the ropes
themselves the necessary stability without the aid of pipes, I proceed as
follows: I connect the ropes, top and bottom, that is above and below 2
ground, by means of adjustable screws or other equivalent, with levers
supported by their fulcra in a position that will enable the ropes stretched >
between them to be maintained in constant tension, which will give the
necessary alternate rise and fall to the plunger, or to other mechanism
to which motion is required to be transmitted.
The former arrangement of cross head, or the latter arrangement of
levers may be actuated by hand, or cattle, or by motive-power engines.
