Improvements in Feed Check Valves for Steam Generators,
Superheaters, and Water or other Liquid Receivers.
I, FRANCIS WILKINSON, of 157 Dukinfield Road, Hyde, in the County of Chester,
Foreman Mechanic do hereby declare the nature of this Invention to be as
follows:-
My invention relates to improvements in feed check valves for steam generators,
superheaters and water or other liquid receivers and the object of my
improvements is to construct a check valve which is readily accessible for
examination and repairs.
I accomplish this object by fitting a check valve controlled by a screwed spindle
or equivalent in a valve casing fitted with a valve plug which controls the ordinary
inlet passage from the feed to the boiler or other receptacle.
When access is desired to the check valve the plug is turned partly round to close
the feed passage at both inlet and outlet and access can then be had to the check
valve by removing its cover.

I, FRANCIS WILKINSON, of 157 Dukinfield Road, Hyde, in the County of Chester,
Foreman Mechanic, 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:-
My invention relates to improvements in feed check valves for steam generators,
superheaters and water or other liquid receivers and the object of my improvements
is to construct a check valve which is readily accessible for examination and repairs,
I accomplish this object by fitting a check valve controlled by a screwed spindle
or equivalent in a valve casing fitted with a valve plug which controls the ordinary
inlet passage from the feed to the boiler or other receptacle.
In the accompanying Sheet of Drawings-
Figures 1 and 2 are side sectional elevations of a feed check valve constructed
according to my present improvements, and Figure 3 is an outside view of the

page_text: In these views, A designates the ordinary check valve, B the hand wheel and
screwed spindle for regulating the same, C the valve casing, D the ordinary feed
inlet passage E the valve plug fitted within the casing C, and F the spindle for
operating the plug E.
When access is desired to the check valve A the plug E is turned partly round
by means of the spindle F to close the feed passage D at both inlet and outlet and
access can then be had to the check valve by removing the cover of the casing C.
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:
In a valve casing provided with an inlet passage from the feed to the boiler or
the like, the combination with the check valve A, of the valve plug E substantially
as and for the purposes herein set forth.
