Improvements in Discs or Washers for Valves and the like...
I, GEORGE BESTWICK, of 192, Green Lane, Patricroft, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
The improvement which forms the subject of this invention relates to the manu-
facture of washers or discs applicable to taps, valves and like uses; for the pur-
pose of this invention I employ the interior hard substance of carrozo pippin that
is obtained after the rind and fruit has been taken therefrom; I cut said hard
substance into sections of suitable form and steep them in a solution of chloride
of lime for forty eight hours or thereabouts, I then form these sections into discs
by turning them in a lathe and fit a brass or other metal cap to one side of said
discs, or insert the screwed end of a spindle therein.
The front may be made flexible by painting with muriatic acid and formed into
a cone or other required shape for taps and valves and like uses.

ashers for valves and the like.
I, GEORGE BESTWICK, of 192, Green Lane, Patricroft, 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:-
"
The improvements which form the subject of this invention relate to the pro-
duction of discs or washers and blanks of various shapes from the Corozo" nut
that is obtained from the corozo pippin after the rind and fruit has been removed
therefrom generally known as the ivory nut or seed of a tropical American palm,
which I treat with a solution of chloride of lime, and employ said discs washers
or blanks in the manufacture of valves, taps, and the like.
For the purposes of this invention I cut the aforesaid nut to a shape correspond-
ing approximately to the shape of the article required or from which said article
may be produced by turning in a lathe, and steep the same in a solution of chlor-
ide of lime for forty eight hours or thereabouts; it is then turned, bored, or other-
wise worked and may be employed separately or in combination with metal or
other material, If for example a valve is to be made, I cut a disc from the afore-
[Price 8d.1

page_text: said nut which I treat with chloride of lime as herein before named, and fit said
disc into a brass or other metal cap in which the screwed end of a spindle is inser-
ted, or said disc may be turned in a lathe and the screwed end of a spindle fitted
therein; the front or other part of the disc may be made flexible by painting with
muriatic acid, and formed by pressure into a cone or other required shape.
By these means, valves, valve seatings, taps and like articles are produced with
indestructable wearing surfaces either wholly from the corozo nut or in combina-
tion with metal or other material.
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:-
The manufacture of discs or washers for valves, taps, and like uses or for parts
of valves taps and the like from the Corozo" or ivory nut that has been treated
with a solution of chloride of lime substantially as herein before described.
