PROVISIONAL SPECIFICATION.
Improvements in Valves.
I, ERNEST HODGES of 585, Oldham Road Newton Heath, Manchester, Brass
Finisher, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improvement in steam, water and other valves, and
has for its object to provide an arrangement by means of which the seating and
valve can be removed from the shell by breaking a single joint only.
In carrying out my invention, I fit within a shell of any suitable construction, a
casing which bears tightly against the lower end of the shell, and is screwed into it
at the upper end, the joint being packed to render it tight. This casing is screwed
internally at its lower end to receive the valve bearing, which is screwed into the
end and is of annular form. Inside this casing and retained in position by the
bearing, the valve is placed furnished with a number of legs or projections, which
form guides extending through the central perforation of the bearing piece. The
valve is prevented from getting out of position by striking against the upper end of
the casing, a small motion being allowed it to permit the water or steam to pass.
The side of the casing is formed with a series of perforations connected with the
outlet. A non return valve is thus provided the seating of which can be moved
from the shell by simply undoing one joint allowing the inside of the valve to be
removed and repaired without interfering with the shell. The shell will thus last
much longer than is at present the case, the wearing parts being removable.

Improvements in Valves.
I ERNEST HODGES of 585, Oldham Road, Newton Heath, Manchester, Brass
Finisher 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 relates to an improvement in steam, water, and other valves, and
has for its object to provide an arrangement by means of which the seating and valve
may be removed from the shell by breaking a single joint alone.
And in order that this invention may be the better understood I have appended
the accompanying sheet of drawings in which-
Fig. 1. is a vertical section of a valve constructed according to this invention.
Fig. 2. is an external view of the inner valve casing, and
Fig. 3. is a plan of the underside thereof.
In carrying out this invention I fit within the outer shell A of the valve a casing
or chamber B which is provided with a screw thread as shown at band which
screws into the outer shell A. Within the casing is the valve proper C for which
a seating is provided at D formed upo the screwed plug E. This plug E is coned

down into the outer shell as shewn in Fig. 1. Perforations G are formed in the
casing B to allow of free communication with the outlet H. The lift of the valve
is governed by the space left between the pin 1 at the top thereof and the top of
the ensing. A nut head is formed at the top by means of which the casing may
be removed.
With a valve constructed as herein described it is only necessary to remove the
inner casing B when the plug E may be withdrawn and the valve is free.
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 steain and other valves the use of an inner movable valve chamber sub-
stantially as herein described and shewn by the accompanying drawings.
2. In steam and other valves the combination of an inner movable valve chamber
or casing with an outer shell substantially as herein described and shown by the
accompanying drawings.
