PROVISIONAL SPECIFICATION.
Improved Means of Applying High Pressure Water to Hydraulic
Machinery.
-
THOMAS TINKER, Peacefield House, Marple Cheshire, Water Engineer
and Surveyor do hereby declare the nature of this invention to be as follows:-
To provide a medium for transmitting hydraulic power to rams, elevators, hoists
and lifts economically and conveniently.
This I accomplish by means of an intermediary cylinder or chamber placed in
any convenient position between the power to be applied and the work to be
accomplished-of a capacity equal to that of the tube or cylinder in which the ram
or shaft supporting, carrying or drawing the load, works.
This intermediary cylinder or chamber to be filled with water or other liquid in
a quiescent state, and not under pressure, which liquid will be acted upon by a
piston working in the intermediary cylinder or chamber, the rod, shaft or ram of
which will be moved by the water under pressure and the quiescent water forced to
alter its form from that of the intermediary cylinder or chamber to that of a tube
or cylinder in which works the ram or shaft supporting, carrying or drawing the
load, and which altered form will be of a less diameter or sectional area than that
of the intermediary cylinder or chamber but of the same cubical capacity. By this
means the stroke of the ram immediately acted upon by the water under pressure
will be shortened and thereby reduce the expenditure of water and consequently
the cost of working.
The water or other liquid in the intermediary cylinder or chamber-quiescent and
not under pressure when not in use; and which can be used repeatedly for the-same
purpose without loss-will furnish the medium for forcing the ram or shaft
supporting, carrying or drawing the load, by being changed from a bulky to an
elongated form, that is to say, from a volume with a greater sectional area to one
of less sectional area, but of a proportionately greater length.

Machinery.
THOMAS TINKER, Peacefield House, Cross Lane Marple near Stockport
Water Engineer and Surveyor, 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 :-
The object of this invention is to provide a medium for transmitting hydraulic
power to rams, elevators, hoists lifts, cranes, presses and motors-hereinafter
generally alluded to described or called, hydraulic plant "-economically,
conveniently and efficiently.

This I accomplish by means of an intermediary_cylinder or chamber A with
piston B and ram and cylinder or tube marked C and D respectively all shewn on the
accompanying drawings and marked respectively Figure 1, Figure 2, and
Figure 3-placed in any convenient position between the power to be applied and
the work to be accomplished, the cylinder A being of a capacity-in the case
דנ...rD

page_text: of elevators, hoists, lifts, and cranes-equal to or in excess of that of the tube or
cylinder in which moves or works the ram or shaft immediately supporting
carrying or drawing the load and in the case of presses and motors of any
convenient capacity varying according to the requirements of the case to which the
invention is intended to be applied.
This intermediary cylinder or chamber A to be filled with water or other liquid
not subject to any force other than that of gravity or of the atmosphere when the
hydraulic plant is not at work; and hereinafter alluded to described, or called
quiescent liquid, which quiescent liquid will be acted upon by the piston B working
in the intermediary cylinder or chamber A. the ram C of which will be moved by
the power water or water under pressure, thereby altering its form from that of the
cylinder or chamber A in the case of elevators hoists lifts and cranes to that of the
tube or cylinder in which moves or works the rain or shaft immediately supporting,
carrying, or drawing the load-and-in-the-case of presses and motors to any form
convenient for the required purpose, and which altered form will be of a less
diameter or sectional area than that of the intermediary cylinder or chamber A,
but of the same cubical contents; by this means the stroke of the ram C
immediately acted upon by the water under pressure, will be shortened propor-
tionately to the area of piston, thereby reducing to a minimum the expenditure
of water.
The quiescent liquid in the intermediary cylinder or chamber A which can be
used repeatedly for the same purpose without any appreciable loss-will furnish
the medium for forcing-in the case of hoists elevators, lifts and cranes-the ram
or shaft supporting carrying or drawing the load by being changed from a bulky to
an elongated form, that is to say from a volume of a greater sectional area to
a volume of less sectional area but of a proportionately greater length,-and in the
case of presses and motors for reducing the pressure of the power water to any
pressure that may be required to suit any particular purpose or case.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what
claim is
1. The interposition of an intermediary cylinder filled with quiescent water
or other liquid and in which works a piston with high pressure ram attached
as described in the Specification for the purpose of applying high pressure water to
hydraulic machinery working or intended to be worked at a lower pressure.
