PROVISIONAL SPECIFICATION.
Improvements in Knife Cleaners.
I, JOHN MARSDEN HECTOR, of Buckland Cottage, Lymington, Hampshire,
Gentleman, do hereby declare the nature of this invention to be as follows:--
According to this invention I use one or more inflated, or spring beds to support
the leather on which the cleaning powder is used. These inflated beds may be
arranged in any kind of knife cleaning machine and the inflation may be by air,
water, or other fluid of like nature, or spring. A simple plan to utilise these inflated
beds I have devised, is to have two beds pressed against each other with the
cleaning leathers between, held in a fixed support, and a frame to hold knives for
the blades to pass between the cleaners and given a reciprocating motion by any
suitable mechanism: or I may use an upright frame with a receptacle for the two
beds, and press the same together by aid of bell crank levers, actuated by a rod
from a pedal operated by the foot, which enables the pressure to be varied
at will.

COMPLETE SPECIFICATION.
Improvements in Knife Cleaners.
I, JOHN MARSDEN HECTOR, of Buckland Cottage, Lymington, in the County
of Hampshire, Gentleman, 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 :-
My invention relates to improvements in knife cleaners.
According to this invention I use one or more inflated or spring beds to support
the leather on which the cleaning powder is used. These inflated beds may be
arranged in any kind of knife cleaning machine, and the inflation may be by air
water or other fluid of like nature or spring. A simple plan to utilise these
inflated beds I have devised, is to have two beds pressed against each other with
the cleaning leathers between, held in a fixed support and a frame to hold knives
for the blades to pass between the cleaners and given a reciprocating motion by
any suitable mechanism or I may use an upright frame with a receptacle for the two
beds, and press the same together by aid of bell crank levers actuated by a rod from
a pedal operated by the foot which enables the pressure to be varied at will.
:
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1. is a front elevation.
Fig. 2, is a side elevation.
Fig. 3, is a cross section of the frame to hold the knives.
Fig. 4, is a vertical section of the inflated or spring beds.
Fig. 5, is a plan of the top of the inflated or spring beds.
I construct my invention with two inflated or spring beds a each being faced with
cleaning leathers 6 these said leathers receive the einery or other, knife cleaning

page_text: powder. The inflated or spring. beds are held in a fixed support c this said support
is bolted or rivetted to two iron uprights or standards k which are braced together
at the base with an iron frame. In each of the uprights or standards k is cut a
slot in order to allow the frame d to hold the knives to work up or down through
a reciprocating motion given to the fly-wheel i by the handle j, crank g and crank
rod h. At the top of the uprights or standards is fitted a shaft m with a crank g
this said crank g is connected to a loop n on the knife frame d. At one end of the
shaft m is fixed a fly-wheel i and at the other end of the shaft is a single crank o to
receive the pedal rod f which is connected to the foot pedal e.
If preferable this machine may be constructed to work by means of the fly-
wheel or by a foot pedal e, both actions may be used in one machine as in Figs. 1,
and 2, or a machine may be made to work with a foot-pedal and another by a
fly-wheel.
The foot-pedale is hinged to the iron frame at the base of the standards k.
The frame d for holding knives of any size is constructed with two raised blocks p
at each end and to these raised blocks is pivotted an iron frame q and also revolving
pins r. On the revolving pins r is fixed diminishing nuts s for the purpose of fixing
the knife handle t under the frame q. The top of the frame g is provided with a
leather pad u for the purpose of preventing the iron frame from injuring any
knife handle. The aforesaid pad is fixed to the frame by rivets between a.
longitudinal plate v and the frame.
9
Preferably the beds a may be pressed together by a screwed bolt c¹ fitted to the
frame of the fixed support c, or one of the beds may be fixed and the other
movable, or any other well known mechanism can be used for the purpose of
pressing the leathers together to grip the blades of knives in order to polish or
clean the same.
1
A tray c is fixed beneath the beds a so as to catch any loose refuse and to prevent
waste of polishing material.
The hereinbefore described machine may be used without a pedal, fly wheel, or
cranked shaft, and in this case the standards would be shortened, and handles d¹
(shown by dotted lines in Fig. 1,) attached to the frame d for the purpose of
working the frame up and down by manual labour in the slot in each of the
standards.
It will be understood that the foregoing is given by way of illustration, and
that the shapes materials and proportions of the parts may be varied in many ways
within the scope of my invention.
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 :-
1. In a knife cleaning machine, the combination of the beds pressed together by
a screwed bolt c¹ fitted to the frame of support c, or one fixed and the other loose,
or pressed together in any well known way so as to press the leathers together,
substantially as herein described and according to the accompanying drawing.
2. In a knife cleaning machine, the combination of handles d₁ and frame d with
short standards or frames, substantially as described.
3. In a knife cleaning machine, the combination of the inflated or spring beds a
with cleansing leathers 6 tray c¹ placed in a fixed support e mounted on uprights k,
with an iron frame at the base, and the slots and the shaft m with a crank g,
crank rod and fly-wheel i for operating the frame d by the handle j, substantially
as herein described and according to the arcompanying drawing.
4. In a knite cleaning machine, the combination of the apparatus with a single
crank o on the shaft m and pedal rod f and foot-pedal e for the purpose of giving a
reciprocating motion by the foot on the foot pedal, substantially as herein described
and according to the accompanying drawing.
5. In a knife cleaning machine, the combination of the apparatus and the
frame d having raised blocks p with an iron frame q plate v leather pad u revolving

page_text: pins and diminishing nuts s, substantially as herein described and according to the
accompanying drawing.
6. In a knife cleaning machine, the combination of the apparatus as illustrated
and described in the foregoing Specification and for the purpose specified.
Dated this 25th day of August 1894.
