PROVISIONAL SPECIFICATION.
Improvements in Knife Cleaners.
We JOSEPH THOMPSON (Engineer) of Decoto in the County of Alameda and
FRANK CORDÉ (Bookkeeper) of San Francisco, both in the State of California,
United States of America, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a simple, inexpensive and durable household implement
that is applicable for use in the cleaning of table knives, the main object of the
invention being to provide for the yielding support of the polishing material and for
the delivery of such material in such quantities as may be required.
It consists of a box-like structure, in one end of which there is a transverse slot
or opening. The box is provided with a lid or cover, upon which there is secured
a strip of polishing leather, and the lid is normally held closed by hooks or
catches.
Within the box is arranged a rubber strip, and above said strip is placed a thin
apertured strip.
In order that these strips may be yieldingly held together a pair of strips placed
side by side are provided, which carry blocks that are provided with springs that
bear against the under face of the lid or cover. The adjacent edges of these strips
are cut away at places and the polishing material which may be emery, pulverised
bath brick, or any other of the well known polishing agents, is placed in the space
above these strips, and the knife to be cleaned is passed in between the rubber and
apertured strips and reciprocated, the polishing material passing downward through
the openings formed by the cuts and apertures.
Dated this 7th day of January 1890.
.COMPLETE SPECIFICATION.
Improvements in Knife Cleaners.
We, JOSEPH THOMPSON (Engineer) of Decoto in the County of Alameda, and
FRANK CORDE (Book-keeper) of San Francisco, both in the State of California,
United States of America, 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 relates to a simple inexpensive and durable household implement
that is applicable for use in the cleaning of table knives; the main object of the
invention being to provide for the yielding support of the polishing material and for
the delivery of such material in such quantities as may be required.
To the ends above named, the invention consists in the novel construction and
combination of the various parts, as will be hereinafter explained and specifically
pointed out in the claims.
Reference is to be had to the accompanying drawings, forming part of this specifi-
cation, in which figure 1 is a plan view of the improved knife cleaner, the lid or
cover being thrown back. Figure 2 is a central longitudinal sectional view of the
cleaner, on line < figure 1; and figure 3 is a cross-sectional view thereof.
Similar letters and figures of reference indicate corresponding parts in all the
views.

page_text: In the drawings, 10 represents a box-like structure in one end of which there is
a transverse slot or opening a. The box 10 is provided with a lid or cover 11 upon
which there is secured a strip of polishing leather 12 and the lid is normally held
closed by hooks or catches 13: Within the box 10 is arranged a rubber strip 14
and above said strip is placed a thin apertured strip 15, the apertures in the said
strip 15 being shewn at b. In order that the strips 14 and 15 may be yieldingly
held together, we provide strips 16 and 16ª which carry blocks 17 that are provided
with springs 18 said springs bearing against the under face of the lid or cover 11.
The approaching edges of the strips 16 and 16ª are cut away at places, as shown
In order that the cleaner may be held against displacement, we form the
bottom of the box 10 with projections that are apertured to receive retaining
screws by means of which the cleaner may be secured to any fixed object.
at c.
In operation, the polishing material, which may be emery-pulverised bath brick or
any other of the well-known polishing agents, is placed in the space above the
strips 16 and 16 and the knife to be cleaned is passed in between the strips 14
and 15, entering through the slot a. The knife, having been placed as just set forth,
is reciprocated, the polishing material passing downward through the openings
formed by the cuts c and apertures b. The polishing strip 12 may be used for forks
as well as knives.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is ;-
In a knife cleaner, the combination, with a box 10 formed with a slot or aperture a
at one end, of a rubber strip 14 located in the bottom of the box, an apertured strip 15
arranged above the strip 14, longitudinal strips 16 and 16ª arranged above the
apertured strip 15 cut away at suitable points along their adjacent edges, blocks
carried by the strips 16 and 16", and springs carried by the blocks and arranged to
bear against the box-lid, substantially as described.
