ALEXANDER ANTONIN GUILLOT, of Marseilles, in France, Civil Engineer. "A
NEW OR IMPROVED TUBULAR VALVE-COCK FOR DISCHARGING, ARRESTING, AND
REGULATING THE FLOW OF ALL FLUIDS UNDER ALL PRESSURES."
My Invention relates to a new or improved tubular valve-cock for discharging,
arresting, and regulating the flow of all fluids under all pressures; it is based on
the law of fluids, viz., that the pressure of a fluid acts in all directions and perpen-
dicularly to the surfaces of the vessel into which it is contained. It has for object
the construction of valve-cocks in such manner that the valve remains in equili.
brium when at work as well as when at rest, the pressure of the fluid acting in a
direction perpendicular to that of the valve, plug, or stopper.
For this purpose the valve-cock is provided with a chamber or reservoir into
which flows the fluid at any pressure, and circulates around the valve plug or stopper
for a portion of its length. This chamber or reservoir terminates in a projection or
socket into which I screw a tubular portion or guide forming a stuffing-box, and
through which passes and slides a hollow cylinder or tube acting as a valve plug or
stopper for discharging, regulating, and arresting the flow of the fluid. At the
outer extremity of such cylinder is fixed another chamber which I provide with a
nozzle for permitting the exit of the fluid, this chamber also acts as a handle to
open or close the cock.
The chamber or reservoir is furnished with a washer of leather or other suitable
material which is placed exactly opposite the cylinder or tubular valve or plug and
forms a tight joint on the valve, being slidden or pushed up against it, and thus
closes the cylindrical or tubular valve and arrests the passage of the fluid.
When a fluid is to be discharged by means of this valve-cock, the handle must be
first drawn or alidden outwards, and the fluid by its own pressure will enter and
flow through the cylindrical or tubular valve and will be discharged through the
nozzle, and when the desired quantity of fluid has been obtained, the handle is
pushed or slidden backward, and the cylindrical or tubular valve abutting against
the leather washer in the pressure chamber or reservoir, the supply will be arrested.
It will be thus easily understood that the pressure of the fluid acting only on the

page_text: surface of the cylindrical or tubular valve cannot displace it, as the pressure acts
perpendicularly to the direction of movement of such valve.
When applied to a communication valve-cock the fluid passes into the pressure
chamber where it flows around a portion of the cylindrical or tubular valve stopper
or plug, which on being drawn out, say by unscrewing a handle attached to the
valve, allows the fluid to pass into a passage communicating with the pipe or other
conduit into which the fluid is to be delivered.
The inner end of the cylindrical or tubular valve stopper or plug is in this
instance fitted with a disc to prevent the passage of the fluid therein, and abuts
when closed against the exit or communicating nozzle in the pressure chamber.
Instead of operating the tubular valve or plug to discharge, regulate, or arrest
the flow of the fluid, the valve-cock may be so contrived that the pressure chamber
is rendered moveable and the valve or plug a fixture.
