SAMUEL CUTLER, of Millwall, in the County of Middlesex. *IMPROVEMENTS IN
GAS VALVES, AND IN THE ARRANGEMENT OF THE PIPES CONNECTING THEM WITH
THE VESSELS WITH WHICH THEY MAY BE EMPLOYED."
"
This Invention has for its objects the making of multiple way gas valves in such
a manner that while great simplicity of construction is attained efficiency is also
ensured, especially when those of the hydraulic form herein after described are
adopted, and the arrangement of the pipes connecting them with the various vessels
with which they may be employed, so as to reduce the great complexity that often
prevails, and at the same time render it possible to work the vessels in any desired
order.
The Invention consists, firstly, in forming a hollow vessel or chamber closed on
all sides, and from the bottom of which and within it rise as many pipes as there
are inlets to the valve. These pipes extend to about half the height of the vessel,
and are connected at their lower portions to the respective mains over which the
valves have control. Each pipe is covered by a bell or cylinder closed at top, and
capable of being raised above the mouth of the pipe. Each of these bells may have
fixed to it a central vertical rod that extends downwards through a guide to the
Driss 71

page_text: bottom or near the bottom of the pipe, and upwards through a stuffing box in the
-top-of-the-chamber,-the-upper-part-of-the-rod-that-protrudes-being screwed-or-
having a rack attached to it. On the top of the outside of the vessel is a frame
through which the screwed ends or racks of the rods pass, each rod being furnished
with a nut and hand wheel or a pinion wheel and handle, so as to raise or lower
the bell over its corresponding pipe pipe. In the upper part of the chamber is formed
an orifice which serves as an outlet. The chamber being partially filled with liquid,
and all the bells down, it will be seen that on gas attempting to pass from any of
the inlets into the chamber it will be unable to do so, the bells being scaled in the
liquid,-but-on-raising-any-one-or-more-of-the-bells-above-the-suface-of-the-liquid-a
free way will be offered to the passage of the gas, and it will pass to the outlet
without obstruction.
In order to prevent any sudden check to the flow of the gas when closing the
valve, and as a means of regulating the said flow, the bottom edge of the bell may be
formed with deep serrations, so as gradually to reduce the area of the gas way, and
in the like manner increase it when opening the valve.
Secondly. Instead of using liquid in the chamber the rising pipes may be
shortened very materially, and the tops of them fashioned into seats for either flat
disc valves or those of a more or less truncated conical form, the valves being
opened or closed by means of the screws or racks in the manner before
described.
In lieu of screws or racks weighted levers may be used, or chains and balance
weights.
In working the valves may be used either as before mentioned, or the upper
orifice may serve as the inlet, when the pipes will become so many outlets.
Thirdly. The arrangement of the connecting pipes on such a system as to reduce
them greatly in number while they admit of the vessels with which they are con-
nected being worked in any desired order, the system being applicable to any
number of purifiers or other vessels.
