Working Engineer do hereby declare the nature of my invention for CLEANSING
OF SURFACE WATER AND SCUM OF STEAM GENERATORS OR BOILERS to be as
follows:-
My invention is for a new or improved apparatus for cleansing or removing the
scum froth or dirty water (by the aid of the steam) which collects near or upon the
surface of the water in the vessels or boilers used in the generation of steam and
which consists of a cone concave plate or dish which may be round or any convenient
shape made of metal or any suitable material placed or fixed in the steam generator
or boiler (by preference in the dome or steam collector allowing room for the free
egress of the steam around the edge or over the back of the cone concave plate or
dish) so as to be level with or slightly above the usual water line having the point
of the cone at the top and if a hollow plate or dish with its concave side to the
water line through the centre or at any convenient part I pass a pipe through the
cone hollow plate or dish to within a small distance of the water but by preference
not so near the water as the edge of the cone hollow plate or dish the pipe thence
passing to the outside of the steam generator or boiler and having a tap or valve
fixed thereon which may be turned or drawn at will so as to allow of the escape of
the dirty water froth and scum which have collected and been drawn to the conc
hollow plate or dish.
The cone, hollow plate, or dish may be lengthened out at one or more sides in
which case the lengthened part or parts may extend to the sides and ends of the
steam generator or boiler or the lengthened part or parts may be shaped like a
trough with the hollow or concavo side to the surface of the water.

page_text: JOHN SMITH, of Grove Road, Wakefield in the County of York, Working
Engineer, do hereby declare the nature of my invention for CLEANSING OF
SURFACE WATER, AND SCUM OF STEAM GENERATORS, OR BOILERS and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
My invention is for a New or improved Apparatus for cleansing, or removing the
Scum froth or dirty Water (by aid of the Steam) which collects near or on the
surface of the water in the Vessels or Boilers used in the Goneration of Steam.
It consists of a Cone Concave Plate or Dish which may be round or any other
convenient shape, one or more of these can be used according to the size of the
Vessel or Boiler to which they are applied. The Cone Concave Plate or Dish is
nade of Wrought Iron, Cast Metal, or any other suitable material placed or fixed
in the Steam Generator or Boiler, in the Dome or Steam collector or it may be
fixed in any other part of the Vessel or Boiler, allowing room for the free egress of
the Steam around the edge or over the back of the Cone Concave Plate or Dish so
as to be level with or slightly above the usual Water line having the raised part
of the Cone Concave Plate or Dish at the top, and the concave side to the Water
line, through the centre or any other convenient part. I pass a pipe through the
Cone Concave Plate or Dish to within a short distance of the Water, but by
preference not so near the water as the edge of the Cone Hollow Plate or Dish, the
Pipe from thence passing to the outside of the Steam Generator or Boiler, and
having a Tap or Valve fixed thereon which may be turned or drawn at will, so as
to allow of the escape of the dirty Water, Froth, or Scum, which have been drawn
to, or is forced by the action of the Steam, or otherwise, to the Cone hollow Plate
or Dish. The Cone Hollow Plate or Dish may be lengthened out at one or more
sides, in which case the lengthened part or parts may be extended to the side and
ends of the Steam Generator or Boiler, or the lengthened parts may be shaped like
a trough with the hollow or concave side to the surface of the water, or any
convenient number of smaller Cone Concave Plates or Dishes may be used.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is, An Improved Apparatus for removing the Scum or Dirt from the surface
of the Water in Steain Generators or Steam Boilers consisting of one or more Cones,
Hollow Plate or Dishes fixed in the said Generators or Boilers with the Concave
side next to the Water, and a Pipo carried from the inside of the Cone Hollow
Plate or Dish to the outside of the vessel or Boiler to which the Apparatus is
applied.
