We ROBERT TURNBULL of 14 Beaconsfield Street, Newcastle on Tyne, Northum-
berland, Naval Architect and MARY BARCLAY of 79 Park Road, Newcastle on
Tyne, Northumberland, do hereby declare the nature of our said invention for
IMPROVEMENTS IN ROTARY MACHINES FOR CLEANING AND POLISHING KNIVES
AND SIMILAR ARTICLES to be as follows:-
*C
"
Our invention relates to machinery for cleaning, polishing and sharpening knives
and similar articles whereby a constant and uniform pressure is exerted on each
side of the blade independent of the tapering form of the blade.
In carrying out our Invention we provide or construct a metal or wooden frame
of the form required. Within this frame we fix a cylinder which is screwed on to
the back of the frame by a nut and screw bolt with collar, the front end of which
projects several inches from the face of the cylinder On to this bolt we fix a
circular disc of metal or wood which is specially made for carrying the knives
which are secured to the circumference of the disc by thumb screws or other
suitable appliances. A handle is also fitted on to the outside of this disc.
On the cylinder is fixed a covering of Linoleum Leather, India Rubber, Brushes,
or parts of each or bristles fixed in the cylinder.
Outside the circumference of the cylinder we make a belt of canvas or steel and
one of Linoleum which is glued thereto. On the outside of the canvas, crosswise,
pieces of thin wood or iron are fixed, which are screwed through both Linoleum
and canvas. The lower part of this belt is screwed on to a piece of wood at the
bottom or other convenient place of the frame a little to one side of the centre.
It is then brought round the cylinder and nearly against the other end which is
connected by a screw working across the bottom projecting out at one side and
operated upon by a small wheel which draws the belt tight or slackens it, formning
a powerful brake as required.
The knives are inserted on the upper side to the right of the centre, A thumb
screw with a band attached is then pressed down over the handle of the knife, it is
then pushed round a little and another knife inserted and secured by similar means.
This is repeated until the number of knives required to be cleaned are all fixed.
Power is then applied to the handle which revolves the knives and rapidly cleans
them as the power is applied.

page_text: The Linoleum has partly a plain surface but the principal part is cut at intervals
pressed out and a thin tapering piece of Linoleum or India rubber put behind it
to keep it out the required shape which forms steps or projections.
The knives travel between those projections which form an elastic bed, it will
thus be seen that as the parts wear, the belt will be lengthened or slackened, by
screwing up a wheel, and in all cases still keep an uniform pressure no matter what
the wear may be.
On the upper side of the metal frame holes are made for the emery powder
or other polishing material necessary for the cleaning of the knives, it then
passes
on to the belt and holes are inserted in this, through which the emery powder or
other polishing material passes on to the knives distributing the powder on to the
rubbing surfaces, the surplus falling on to the bottom of the casing and is caught
in a save all, the powder is lifted up and placed in the top again.
The linoleum may be cut on an angle or across in the form of tapes, so long as a
raised surface is obtained both on the upper and lower sides of belt and on
cylinder.
'
It will thus be seen that any number of knives may be cleaned by increasing
the diameter of the cylinder. It being distinctly understood that the knives
themselves revolve and that the linoleum leather, India rubber, brushes and other
apparatus used for cleaning knives remain stationary.
The head or upper part of the machine should fall back to about an angle of
from 50 to 70 degrees, this keeps the shoulders of the knives against the cleaning
parts.
In some cases the cylinder is screwed on by two or three nut and screw bolts
the centre bolt working loosely and the circular disc keyed on to it. The handle
may then be fitted on to the opposite end of bolt at back of the machine also a
small fly wheel may be fixed if required at back.
The frame may be partly of iron and partly of wood.

Knives and similar Articles.
We ROBERT TURNBULL of 14 Beaconsfield Street, Newcastle on Tyne, Northum-
berland, Naval Architect and MARY BARCLAY of 79 Park Road, Newcastle on
Tyne, Northumberland, do hereby declare 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 Machines for cleaning, polishing, and sharpening knives
and similar articles, whereby a constant and uniform pressure is exerted on each
side of the blade independent of the tapering form of the blade.
In carrying out our invention, we provide or construct a metal or wooden frame
of the form required. Within this frame we fix a cylinder, which is screwed on to
the back of the frame by a nut and screw bolt with collar, the front end of which
projects several inches from the face of cylinder. Onto this bolt we fix a
circular disc of metal or wood which is specially made for carrying the knives
which are secured to the circumference of the disc by thumb screws or other
suitable appliances, a handle is also fitted onto the outside of this disc.
On the cylinder is fixed a covering of Linoleum, Leather, India rubber, Brushes,
or parts of each, or Bristles fixed in the cylinder.
Outside the circumference of the cylinder we make a belt of canvas or steel and
one of linoleum which is glued thereto. On the outside of the canvas crosswise,
pieces of thin wood or iron are fixed which are screwed through both linoleum and
canvas. The lower part of this belt is screwed on to a piece of wood at the bottom
or other convenient place of the frame a little to one side of the centre. It is
then brought round the cylinder and nearly against the other end which is
connected by a screw working across the bottom projecting out at one side, and
operated by a small wheel, which draws the belt tight or slackens it, forming a
powerful brake as required.
The knives are inserted on the upper side to the right of the centre, a thumb
screw with band attached is then pressed down over the handle of the knife, it is
then pushed round a little, and another knife inserted and secured by similar or
equivalent means. This is repeated until the number of knives required to be
cleaned are all fixed.
.
Power is then applied to the handle which revolves the knives and rapidly cleans
them as the power is applied.
The linoleum has partly a plain surface but the principle part is cut at intervals
pressed out and a thin tapering piece of linoleum or india rubber put behind it to
keep it out to the required shape, forming steps or projections.
The knives travel between those projections, which form an elastic bed. It will
thus be seen that as the parts wear the belt will be lengthened or slackened by
screwing up a wheel and in all cases still keep an uniform pressure no matter what
the wear may be.

page_text: On the upper side of the metal frame, holes are made for the emery powder or
other polishing material necessary for the cleaning of the knives, it then passes
on to the belt having holes, through which the emery powder or other polishing
material passes on to the knives; distributing the powder on to the rubbing surfaces,
the supplies falling on to the bottom of the casing and is caught in a save all, the
powder is lifted up and placed in the top again.
.
The linoleum may be cut on an angle or across in the form of tapes so long as a
raised surface is obtained both on the upper and lower sides of belt and on
cylinder.
It will thus be seen that any number of knives may be cleaned by increasing the
diameter of the cylinder. It being distinctly understood that the knives themselves
are moved round and that the linoleum, leather, india rubber, brushes, and other
apparatus used for cleaning knives remain stationary.
The head or upper part of the machine should fall back to about an angle of, from
50 to 70 degrees, this keeps the shoulders of the knives against the cleaning parts.
In some cases the cylinder is screwed on by two or three nut and screw bolts,
the centre bolt working loosely and the circular disc keyed on to it. The handle
imay then be fitted onto the opposite end of the bolt at the back of the machine,
also a small wheel may be fixed if required, at back.
The frame may be partly of iron and partly of wood.
The mode of carrying this invention into effect will be understood by reference
to the annexed drawings in which Figure 1 is a part sectional end elevation.
Figure 2 shows a side view of same. Figure 3 is a half view of cylinder end and
Figure 4 shows a view of the linoleum with laps.

Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
1. In a machine for cleaning and polishing knives and similar articles the
rotating frame A which support and carry the knives in a circular direction
between the cleaning media as set forth.
2. In a knife cleaning machine the appliances by which pressure on the knives
can be varied at will as herein set forth.
3. The appliances or means for fixing the handles of the knives in the rotating
frame as set forth and shown in the annexed drawings.
