ARTHUR CHARLES CHURCHMAN 31, Henley Road Ipswich Suffolk Tobacco
Manufacturer do hereby declare the nature of this invention to be as follows :-
My invention consists of an improvement in knives used in tobacco manufacture
for cutting the tobacco leaf. Instead of the flat or plane surface or surfaces of
the knife or knives hitherto used, I introduce a grooved, fluted, beaded, or indented
surface or surfaces, such grooves, flutes, beads or indentations produce a serrated
or irregular instead of a straight cutting edge on the knife owing to their being
carried vertically over part or the entire surface or sui faces or bevel or bevels of
the knife. This serrated or irregular edge when used in cutting tobacco imparts
its serrations or irregularities to the tobacco cut, thereby producing waved or
irregular threads, flakes or shreds of tobacco, and thus enhancing its value and
appearance in addition to which a knife having its edge so seirated cuts with
greater facility and retains its sharpness louger than a knife having a straight
edge.
Now my claim consists in the introduction of grooves flutes, beads or other
indentations on one or both sides or on the bovel or bevels of tobacco cutting
knives, producing thoroby a serrated or regular cutting edge, such grooves flutes,
beads or other indentations being of any width, depth, size or shape as may be found
desirable, and also in the improved appearance and value of the manufactured
tobacco thereby produced.

An Improvement in Knives Used in the Manufacture of Tobacco,
for Cutting the Tobacco Leaves, Cakes, or Plugs.
I ARTHUR CHARLES CHURCHMAN of 31 Henley Road Ipswich in the County
of Suffolk Tobacco Manufacturer 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 consists of an improvement in knives used in tobacco manufacture
for cutting tobacco leaf cakes or plugs and instead of making the surface or surfaces
of such knives plane or flat as at present I form in such surfaces a series of grooves
flutes beads or indentations which grooves flutes beads or indentations produce &
serrated or irregular cutting edge on the knife owing to the said grooves flutes
beads or indentations being vertically over part of or the whole of the surface or
surfaces or bevel or hevels of the knife. This serrated or irregular edge when the
knife is used for cutting tobacco imparts its serrations or irregularities to the
tobacco cut thereby producing waved or irregular threads flakes or shreds of
tobacco and thus enhancing its value and appearance in addition to which a knife

The same letters denote the same parts in all the figs.
a is the knife for use with a machine for making
cut
tobaccos bb are slots
therein to receive bolts or studs by means of which the knife is attached to the
machine c is the bevil at the back of the knife. As shewn at Figs. 1 2 & 3 the
front of the blade and the cutting edge thereof 18 grooved which when the machine
to which the knife is attached is in operation will give to the sheds threads or
flakes of cut tobacco a waved outline thereby enhancing the value and appearance
of the product of the machino. Furthermore knives so constructed out more
easily and reque sharpening less frequently than knives having a straight edge.
The back of the knife may be grooved as well as the front if desired and the
groes may be continued from bottom to top of the Luife if desired.
In Fig. 4 the edge and frout of the knife are serrated.
In Fig 5 the edge of the knife aud the front thereof are fluted.
In Fig. 6 the edge of the knife and the front thereof are headed.
Either of the herembefore mentioned forms of knife will give good results and
I do not bind myself to any particular form of grooves flutes indentations or
bending on the surface or edge of the knife as nuy suitable form of grooves flutes
beads or indentations may be used without departing from my invention, but,
Having now particularly described and ascertained the nature of iny said inven-
tion aud in what manner the same is to be performed, I declare that what [
claim is;
1. Knives for cutting tobacco leaves cakes or plugs having the surface or
surfaces and edges thereof fluted grooved serrated beaded or indented substantially
as herein before specified and for the purpose stated.
2. The constructions of kuives for cutting tobacco leaves cakes or plugs as
shewn by the accompanying drawings.
