PROVISIONAL SPECIFICATION.
Improvements in and relating to Fuel Economisers for Heating
Boiler Feed Water.
I THOMAS SYKES of 385 Stockport Road Manchester in the County of
Lancaster, Engineer do hereby declare the nature of this invention to be as
follows:-
My invention relates to the top boxes of fuel economisers of the vertical type
such as are ordinarily employed in connection with steam boilers. My invention
has for its object an improvement in the construction and method of application of
the caps used for the purpose of closing the holes in the top box the said holes
being formed immediately above the pipes forming the body of the economiser.
In carrying my said invention into effect I form circular nipples surrounding
the holes and I accurately bore the hole to the required size. I turn or face each
nipple and also form an angular surface like a valve seat at the upper edge of
the hole. The cap which is used to close the holes is formed with a cylindrical
nipple or shank and a circular flange on the upper surface of which is a square
nipple by which the cap can be revolved. I form corresponding screw threads
in the hole and on the nipple of the cap so that the cap can be screwed into
the hole. At the junction of the nipple and flange of the cap I form a corre-
sponding angular surface to that at the top of the hole so that when the cap is
screwed down into the two surfaces form a close and accurate joint.

I, THOMAS SYKES of 385 Stockport Road Manchester in the County of
Lancaster Engineer 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 the top boxes of fuel economisers of the vertical type

has for its object an improvement in the construction and method of application of
the caps used for the purpose of closing the holes in the top box the said holes
being formed immediately above the pipes forming the body of the economiser.
In carrying my said invention into effect I form circular nipples B surrounding
the holes and I accurately bore the hole to the required size. I turn or face each
nipple B and also form an angular surface F like a valve seat at the upper edge of
the hole. The cap C which is used to close the hole is formed with a cylindrical
nipple or shank C' and a circular flange C on the upper surface of which is a
square nipple D by which the cap can be revolved. I form corresponding screw
threads E in the hole and on the nipple of the cap so that the cap can be screwed

corresponding angular surface to that Fat the top of the hole so that when the cap
is screwed down the two surfaces form a close and accurate joint.
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
The combination with and application to the top boxes of fuel economisers of
caps constructed substantially as herein described and illustrated.
