A New or Improved Device for Collecting Fur or Deposit in Kettles
and Boilers.
JOHN WILLIAM OAKFORD Oak Street Fakenham, Norfolk, Tinman &c. do
hereby declare the nature of this invention to be as follows:-
A number of metal rays of suitable size & material, radiate from a common
centre, & are fixed to a base of suitable material and weight, to enable the whole
to maintain an upright position in the kettle or boiler, the object being to obtain as
large a surface as possible in the most compact form, so as not to unduly lessen the
capacity of the vessel in which it is placed. For engine boilers the tubes, flues, or
any available part may be jacketed, or clad, with rays, as described above.
Dated this 19th day of March 1897.

JOHN WILLIAM OAKFORD,
Oak Street, Fakenham, Norfolk.
A New or Improved Device for Collecting Fur or Deposit in Kettles
and Boilers.
I, JOHN WILLIAM OAKFORD of Oak Street, Fakenham, Norfolk, Tinman, 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 has for object the lessening or prevention of incrustration in
boilers and other vessels used for heating water. The principle on which it is
based is that of affording a large surface of metal on which the calcareous matter
can be deposited while not appreciably decreasing the space available for the
water.
It consists of a number of metal plates of equal or nearly equal dimensions
radiating from a common centre, and attached to a base of suitable size and weight
to enable the article to maintain an upright position.
I will now describe the invention with reference to the accompanying drawings,
in which:
Fig. 1 shows a view in perspective of one of my incrustators with 10 fans. Any
suitable number of fans may be used. A ring or knob may be placed at the top,
as shewn in Fig. 2 for convenience of carrying or lifting.
Fig. 2 shows an elevation and plan of the same on a reduced scale. In the plan
view the top ring is omitted, and the base is shewn in dotted lines.
a, a are the fans or flat plates joined at the common centre b. c is the base. dis
a ring handle.
The mode of operation is to insert one or more of the articles in the kettle or

page_text: boiler, and allow the calcareous deposit to form on them. They can then be
removed and replaced others, or they can be cleared of deposit and restored to use.
It will be obvious that by doubling or trebling the metallic surface exposed to the
action of the water, a proportionately less amount of deposit will be formed on the
surface of the vessel.
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 l
-claim is:
An incrustator or device for collecting fur or deposit consisting of a series of
plates of suitable material connected to a common centre, and mounted on a
suitable base and with or without a handle; as herein described and set forth.
Dated this 3rd day of May 1897.
