PROVISIONAL SPECIFICATION.
Improvements in Valves for Water-gas Plant.
I, RICHARD NICKERSON OAKMAN, the Younger, of Greenfield in the State of
Massachusetts, United States of America, Gentleman, do hereby declare the
nature of this invention to be as follows:-
This invention is intended more particularly for use with that class of water
gas plant described in the Specifications of two several Letters Patent granted
to Burdett Loomis dated respectively:-5 November, 1888, No. 15983, &
4 June 1889, No. 9279, and the invention consists in a novel arrangement of
swivel valve to close the passage (previous to making water gas) by which the.
producer gas is drawn off from the generator.
In carrying out this invention, I employ a flat casing, towards one side of which
I form inlet and outlet openings, with which are connected respectively a pipe from
the generator, and a pipe to the exhauster.
In this casing I pivot, by one side, a frame having a cylindrical recess in which
is placed a loose disc valve.
The faces of the valve and seat are faced to obtain a good joint.
The pivot of the frame extends through a stuffing box, and is provided with a
lever handle by which the valve may be swung from one side to the other, as
occasion may require.
When the fuel in the generator has been brought to a high state of incan-
descence, and it is desired to make water gas, the valve is closed so as to break
all connection between the generator and exhauster, and the steam is then turned
on, the water gas thus produced passing off through other passages provided for
the purpose.
As the valve slides over the face of its seat, it clears the seat of any dirt, and
the valve being loosely retained, is held firmly on its seat by the pressure of the
gases.
Dated this 22nd day of December 1890.

Improvements in Valves for Water-gas Plant.
I RICHARD NICKERSON OAKMAN, the Younger, of Greenfield in the State
of Massachusetts, United States of America, 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 :-
This invention is intended more particularly for use with that class of water
gas plant described in the Specifications of two several Letters Patent granted
to Burdett Loomis, dated respectively 5th Nov. 1888, No. 15983, and
June 4th 1889, No. 9279, and the invention consists in a novel arrangement of
swivel valve to close the passage (previous to making water gas) by which the
producer gas is drawn off from the generator.
In carrying out this invention, I employ a flat casing, towards one side of which
I form inlet and outlet openings, with which are connected respectively a pipe
from the generator and a pipe to the exhauster.
In this casing I pivot, by one side, a frame having a cylindrical recess in which

The pivot of the frame extends through a si

occasion may require.
เ
When the fuel in the generator has been b
ve and seat are faced to obtain
g box, and is provided with a
rom one side to the other, as
ht to a high state of incan-
descence, and it is desired to make water gas,---valve is closed so as to break
all connection between the generator and exhaust
on, the water gas thus produced passing off thro
the purpose.
As the valve slides over the face of its seat
the valve being loosely, retained, is held firmly
gases.

In the accompanying drawing,
Fig. 1 is a plan view of the improved valve.
Fig. 2 is a plan view with the valve and cover re
Fig. 3 is a longitudinal section.
Fig. 4 is a transverse section; and
and the steam is then turned
other passages provided for
...rs the seat of any dirt, and
seat by the pressure of the
ed.
Figs. 5 show. in plan and cross section the valve frame.
A is the flat casing composed of three parts, name a base plate A, to which is
bolted a cover or upper part A¹, a lateral extension. A² being bolted or otherwise
secured to the base and cover.
B is the inlet for the gases from the generator, and B¹ is the outlet to the
exhauster.
C is the valve seat, which is detachable, and is secured to the base A. by bolts
and nuts a a.
D is an annular frame with a lug fitted to receive a spindle D; which is passed
through a suitable stuffing box in the cover A', and provided with a handle D²,
by which it may be turned.
E is the valve consisting of a disc with an annular flange which fits loosely in
the frame D.
In the normal position of the valve, the passage through the casing is open, and
the valve E is swung back into the lateral extension A, ribs C, flush with, and
connected to the detachable valve seat, being provided to support it in that
position.
The valve, when being closed, slides over the face of its seat, and clears the
seat of any dirt, and it is held firmly to its seat by the pressure of gases on the
top.
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 I
claim is :-
1. In a valve for use in water gas plant, the combination of a loose disc,
suitably operated, and a detachable seat, as set forth.
2. A valve for water gas plant constructed, arranged, and operating substantially
as herein shown and described.
