PROVISIONAL SPECIFICATION.
Improvements in Knife-cleaning Apparatus.
We, BARNARD ALFRED SPAULL, of 61, Chancery Lane, London, W.C., Engineer,
and FREDERIC GEORGE BATE, of 55 and 56, Chancery Lane, London, aforesaid,
Commission Agent, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide a simple and efficient apparatus for
cleaning table knives, without straining the handles, and other disadvantages
which are well known with respect to rotary machines, and to this end the
apparatus consists of two parts, namely, a holding device for the handles of the
knives, and a rubbing device for cleaning the blades.
The holder consists of a cast metal block, having recesses with taper walls,
strips of rubber or other suitable material being provided to receive the handles.
The block is also formed with lugs, to which a flat plate with a handle is hinged
or pivotted, and this plate is preferably covered, on the underside, with a strip
of rubber or other suitable material, which will form a gripping surface.
The block is also provided with lugs, by which it may be secured to a table,
by_wood screws or clamps.
In working the apparatus, the handles of the knives are laid in the recesses
on the block; the hinged plate is then brought down upon them, and, with but
slight pressure, they are firmly held in position.
The rubbing device consists of two strips of suitable material hinged together
at one end, the free ends forming handles, which are gripped by the hand, and
pressed together, according to any desired pressure.
These strips are provided with longitudinal pads, and are inserted in tubes
of some suitable material of a honeycomb character, or having interstices
intended to receive and hold the polishing powder. These tubes constitute the
rubbing surfaces of the rubber or rubbing device.
A guard is placed at the handle end, to prevent the hand coming against the
blades of the knives, and in front of the guard is a kind of curtain of felt or other
material, to prevent the polishing powder working out at the end of the rubber,
and soiling the hand. The blades of the knives to be cleaned are placed between
the covered strips of the rubber, which is then moved backward and forward
over the blades, thus cleaning and polishing them.

We, BARNARD ALFRED SPAULL, of 61, Chancery Lane, London, W.C., Engineer,.
and FREDERIC GEORGE BATE, of 55 & 56, Chancery Lane, London, aforesaid,
Commission Agent, 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 object of this invention is to provide a simple and efficient apparatus for
cleaning table knives without straining the handles, and without other dis-
advantages which are well known with respect to rotary machines, and to this
end the apparatus consists of two parts, namely, a holding device for the handles
of the knives, and a rubbing device for cleaning the blades.
In the accompanying drawings Fig. 1 is a side view of the holding device,
Fig. 2 being a plan view of the same.

The holder consists of a cast metal block A, having recesses B, with taper walls,
strips of rubber or other suitable material, C, being provided to receive the
handles. The block A is also formed with lugs D, to which a flat plate E to be
called a holding plate, with a handle E', is hinged or pivotted, and this plate is
preferably covered on the underside with a strip of rubber or other suitable
material F, which will form a gripping surface.
The block is also provided with lugs G, by which it may be permanently secured
to a table by wood screws, and it has also a bar H to receive one arm of a clip or
cramp, by which the block may be secured temporarily to a table or board.
In working the apparatus, the handles of the knives are laid across the block
in the recesses (see Fig. 2); the hinged plate E is then brought down upon them,
and, with but slight pressure of the hand, they will be firmly held in position.
The rubbing device consists of two strips J, of suitable material, hinged
together at one end, the free ends forming handles, which are gripped by the hand
of the person using the apparatus, and pressed together according to any amount
of pressure it is desired to apply.
These strips are provided with longitudinal pads K, of felt or any other suit-
able material, and are inserted in tubes or sleeves L, of some suitable material
of a honeycomb character, or having interstices intended to receive and hold the
polishing powder. These tubes or sleeves L, which may be of wovern fabric,
constitute the rubbing surface of the rubber or rubbing device.
A guard M is placed at the handle end of the rubber, to prevent the hand
coming against the blades of the knives, and in front of the guard is a kind of
curtain of felt or other material N, to prevent the polishing powder working out
at the end of the rubber and soiling the hand. The blades of the knives to be
cleaned are placed between the covered strips J of the rubber, which is then
moved backward and forward over the blades, thus cleaning and polishing them.
By the use of tubes or sleeves forming the rubbing surface, this surface can
be readily renewed, when worn out, by slipping off or removing the worn tube,
and replacing it by a fresh one.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
∙1. In a knife cleaning apparatus consisting of a holding device and a rubbing

page_text: or cleaning device, the holding device as shewn and described, and consisting of
a recessed block to receive the handles of the knives, and a holding plate hinged to
the block, and intended to close down on the handles, and provided with a
handle whereby sufficient pressure to firmly hold the knife handle may be readily
given by the hand of the user, as set forth.
2. In a knife cleaning apparatus consisting of a holding device and a rubbing
or cleaning device, the rubbing device as herein shewn and described, and con-
sisting of strips of suitable material formed with handles at one end, and hinged
together at the other, having pads of felt or other suitable material on the inner
faces, and adapted to be inserted in tubes or sleeves of woven fabric or other
material, having interstices to hold the polishing powder, as set forth.
3. In a rubbing or cleaning device for knife cleaning apparatus, forming the
rubbing surface of removable tubes or sleeves of woven fabric, or other material
having suitable interstices, as herein shewn and described, and for the purpose
set forth.
4. The knife cleaning apparatus as herein shewn and described, and consisting
of two parts, namely, a holding device adapted to give the requisite pressure,
simply by the action of the hand of the user, and a rubbing device having a
rubbing surface of a woven fabric or other suitable material, provided with inter-
stices, to retain the polishing powder, as set forth.
