PROVISIONAL SPECIFICATION.
Improvements in Feeding Steam Boilers with Water and in the
Means therefor.
We, RICHARD WITHINGTON BROMILEY SANDERSON, of Office D, Royal
Exchange. Manchester, in the County of Lancaster, Cotton Merchant, and
FRANKLIN Hoop, of 6 York Street, Charles Street, Manchester aforesaid,
Engineer, do hereby declare the nature of this invention to be as follows:-
Our invention relates to improvements in feeding steam boilers and in the means
therefor, and the chief object of our improvements is to feed the water into the
boiler in the form of spray by a spreading appliance which can be employed
without necessitating the cutting of fresh holes in the boiler shell.
We accomplish this object by connecting to the ordinary feed pipe a pipe
which extends horizontally from the feed to near the opposite end of the boiler
or any shorter distance. The end of this pipe is closed and it is supported in
any convenient manner and to it is connected a branch pipe or two
branch pipes each branch supporting a spreader or distribuitor consisting of a
chamber having a narrow annular outlet.
or more
The feed water entering the boiler by the feed pipe is conducted by the
horizontal pipe to each distributor by which it is discharged through the annular
outlet above named into the boiler in the form of spray.
The construction and form of the distributor may be varied or modified to suit
different requirements.
Dated this 15th day of April 1891.

COMPLETE SPECIFICATION.
Improvements in Feeding Steam Boilers with Water and in the
Means therefor.
We, RICHARD WITHINGTON BROMILEY SANDERSON, of Office D, Royal
Exchange, Manchester, in the County of Lancaster, Cotton Merchant, and
FRANKLIN Hoop, of 6 York Street, Charles Street, Manchester, aforesaid,
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:-
Our invention relates to improvements in feeding steam boilers and in the means
therefor, and the chief object of our improvements is to feed the water into the
boiler in the form of spray by a spreading appliance preferably of mushroom shape
which can be employed without necessitating the cutting of fresh holes in the
boiler shell.
We accomplish this object by connecting to the ordinary feed pipe a pipe which
extends horizontally from the fed to near the opposite end of the boiler or any
shorter distance. The end of this pipe is closed and it is supported in any con-
venient manner and to it is connected a branch pipe or two or more branch pipes
each branch supporting a spreader or distributor consisting of a chamber having a
narrow annular outlet.
The feed water entering the boiler by the feed pipe is conducted by the
horizontal pipe to each distributor by which it is discharged through the annular
outlet above named into the boiler in the form of spray.

page_text: And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Figure 1 is a side elevation of part of a steam boiler with a portion of the shell
removed to show the application of our improved feed water spreader and Fig. 2 is
a detail sectional view on an enlarged scale of our improved feed water spreader.
In Fig. 1-a represents the boiler shell, 6 the valve for controlling the admission
of the feed water, and e a horizontal pipe carried from such valve either the full
length of the boiler or any shorter distance; to this pipe is fitted a branch pipe d
suitably stayed to carry our improved spreading device which is placed near the
top of the boiler.
The spreading device, see Fig. 2, is fitted to the end of the branch pipe and
consists of a conical mouthpiece e and flange to which the disc is bolted by
bolts the periphery or outer edge of the disc being bevelled or bent over so as
to leave a narrow annular space between it and the flange e' through which feed
water passes and falls in the form of spray into the steam space of the boiler and on
to the water and thus avoids contact with the shell or flues of the boiler.
By this arrangement cold water could be applied to a boiler and be thoroughly
heated before it is admitted through the spreading device in the form of spray to
the steam space.
Any suitable number of spreading devices could be applied to a boiler.
The construction and form of the spreader or distributor may be varied or
modified to suit different requirements.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
1. The combination with the feed pipe of a boiler, of a feed water spreading
and distributing appliance or appliances constructed and operating substantially
in the manner and for the purposes herein set forth.
2. The feed water spreader or distributor consisting of the following parts in
combination namely a supply pipe such as d the conical mouthpiece and the
disc arranged as shown in Fig. 2.
