COMPLETE SPECIFICATION.
Improvements in Knife Cleaners.
We, CLAUDE WILLIAM BUCKLE, Gentleman, of 20, Cambridge Road, The
Avenue, and FREDERICK HOWARD ELLISTON, Law Clerk, of 61, Livingstone
Road, both of Southampton, in the County of Hampshire, and CHARLES HINDLE,
Agent, of 3, Cursitor Street, in the County of London, 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 knife boards or cleaners chiefly for domestic use and has
for its object to provide a device which will be more handy in use and will clean off
the rust and stain, and polish the knife blades more efficiently than those heretofore
in use.
According to our invention we form the acting surface of the knife cleaner with
a suitable transverse curve, so that in cross section it is of a convex configuration
instead of flat or level as has hitherto been the case. The foundation is or may
be of wood and is suitably curved as described to receive the acting surface, the
material of which may be "Lincrusta," leather, or other suitable material or
substance presenting a plain but suitably refractory or gritty surface.
Further, according to our invention we serrate this convex surface, that is, in or
upon it we form a series of serrations in the form of either longitudinal or
approximately longitudinal corrugations or alternate solid ridges and open grooves
of suitable shape, section, and area, so that the completed surface is both convex
transversely, and serrated, corrugated, or grooved longitudinally or in any suitable
direction or directions.
In use the bath-brick or other cleaning and polishing agent fills up flush the
said serrations, corrugations, or grooves, so that the convex surface becomes
practically solid, being composed as stated of alternate strips of solid material
and polishing agent, and whether the acting surface be plain or serrated, in
either case the necessary pressure upon and bending of the knife blades in
contact with such surface during cleaning and polishing ensures increase of
friction and hence better polishing qualifications.
The accompanying drawings illustrate our invention.
Fig. 1 is an end view showing the knife cleaner with a plain convex surface;
Fig. 2 illustrates in perspective our improved knife cleaner with the convex
surface corrugated;
Fig. 3 is an end view with corrugations; and
Fig. 4 the same with grooves shown as being filled up with the polishing
material.

B is the foundation, A. the acting convex surface, a a the corrugations or grooves
formed in same, and c the polishing agent filling the grooves a. The ends of the
corrugations or grooves may be stopped in any convenient manner to better retain
the polishing agent c.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what
we claim is :-
1. A knife cleaner formed with a transversely curved convex acting surface as

or grooves formed therein or thereupon substantially as and for the purpose above
set forth.
