PROVISIONAL SPECIFICATION.
Improvements in Circular Cutters for Cutting Tobacco Leaves,
Paper, Leather, and similar Materials.
We, EBENEZER RICHARDSON, of Woodseats, Sheffield, Mechanic, and GEORGE
WILLIAM ELLIOTT of Meersbrook Park Road Heeley, Sheffield, Engineer, do
hereby declare the nature of this invention to be as follows:-
Circular cutters have hitherto been made in such a form that it is difficult to
resharpen them when they have become blunt with use. In most cases it has been
necessary to take them out of their handles or carriers and fix them in a lathe for
this purpose.
The object of this invention is to render the opperation of resharpening very
easy & obviate the necessity of taking them out of their handles or carriers for
resharpening.
This is effected by making the cutters of a dish form, one side being dished, or
hollowed out, so that the cutting edge projects on that side beyond any other part
of it, and also sufficient to allow it to be rubbed on a whetstone or other sharpening
medium, without allowing the head of the centre pin on which it revolves, coming
in contact with it.
The cutter is attached to its handle or carrier by means of a pin screwed at one
end to attach it to the handle or carrier, and plain in the centre for the cutter to
revolve upon, and having a head on the unscrewed end to prevent the cutter from
coming off it.
With this mode of attachment the handle or carrier is on the rounded or convex
side of the cutter, the hollowed or concave side being without obstruction of any
kind.
The cutters may also be attached to their handles or carriers, by means of pins
having a bearing on both sides of the cutters, in which case it is more difficult to
resharpen them without detaching them from their handles or carriers, but much
easier than those at present in use.

EBENEZER RICHARDSON of Woodseats near Sheffield, Mechanic, and GEORGE
WILLIAM ELLIOTT Meersbrook Park Road, Heeley, Sheffield Mining and
Mechanical Engineer 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:-
Circular cutters have hitherto been made in such a form that it is difficult to

page_text: re-sharpen them when they have become blunt with use. In most cases it has been
necessary to take them out of their handles or carriers and to fix them in a lathe
for this purpose. The object of this invention is to render or make easy the
operation of re-sharpening and obviate the necessity of taking them out of their
handles or carriers for re-sharpening.
This is effected by making the cutters as shown in Figs. 1, 2 & 3 on accompanying
drawings.
Fig. 1. is the side view of the cutter with part of handle or carrier shown
Fig. 2. is a front view with part of handle or carrier shown,
Fig. 3. is an enlarged section of the cutting wheel.
The cutting wheel in Figs. 1, 2 & 3 is of a dish forin, that is, one side being dished
or hollowed out so that the cutting edge b, b, b, projects on that side beyond any
other part of it, and also sufficient to allow it to be rubbed on a whetstone or other
sharpening medium without allowing the head of centre pin c, c, c. on which it
revolves coming in contact with the whetstone or sharpening medium. The cutter
is attached to its handle or carrier D. D. D "so that it may revolve" by means of
the pin c. c. c. which is screwed at one end to attach it to the handle or
carrier D. D. D, the pin c. c. c. to be plain, or smooth where the cutter A. A. A.
revolves upon and to have a head G on the unscrewed end to prevent the
cutter A. A. A. from coming off, or detached from handle or carrier D. D. D,
with this mode of attachment the handle or carrier D. D. D. is on the rounded or
convex side e, e. e. of the cutter, the hollowed or concave side f, f, f, being without
obstruction of any kind.
The cutters may also be attached to their handles or carriers by means of pins
having a bearing on both sides of the cutter wheel in which case it would be more
difficult to re-sharpen them without detaching them from their handles or carriers,
but much easier than those at present in use.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :
(1.) The right to make and sell circular-cutters, disbed or hollowed on one side
substantially for the purpose and in the manner herein described and illustrated.
