An Improved Bread or other Knife.
We, FRANCIS HAYES and FRED JAMES LEWIS, both of the City of London,
in the County of Middlesex in the Province of Ontario, Canada; and both Manu-
facturers, 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
-
This invention relates particularly to a knife used to cut loaves into slices
but it may be used as a knife or saw to cut meat, or for cutting fruits or vegetables
of any kind.
The object being to readily and easily cut loaves into thin slices without
forming crumbs, at the same time, all danger of cutting or injuring the operator
is completely prevented..
And this invention consists of a knife in the cutting edge of the blade of which,
notches are formed at certain intervals, leaving a portion of the cutting edge of
the blade between each notch, and forming cutting breasts or angular cutting edges
of the sides of said notches, and then forming shallow grooves for a short distance
back from, and on a line with said notches, in one side of the blade, as will be
hereinafter first fully set forth and described, and then pointed out in the claim.
Reference being had to the accompanying drawings wherein,
Fig. 1. is a side elevation of a knife, embodying our invention.
Fig. 2. is a cross sectional view of the blade on the line a, a, of Fig. 1.
Fig. 3. is a longitudinal sectional view of the blade on the line a, a, of Fig. 1.
H, designates the handle; and, B, the knife blade secured thereto.
This knife blade, B, is preferably bevelled or sharpened on one side only as
shown at, b, Fig. 2.
And in the cutting edge of this knife blade, B, notches, n, are formed at intervals
apart, leaving portions, e, of the cutting edge of the blade between each notch,
as shown in Fig. 1. of the accompanying drawings; and, g, designates shallow
grooves formed in one side only of the knife blade in a line with the notches, n, and
a short distance back and from the cutting edge of the blade; as shown in Figs. 1.
and 3, of the accompanying drawings.
The sides of the notches, n, are sharpened, and form short breasts or cutting
edges, 8, which abut against small independent portions of the bread, meat, &c. at
an angle to that at which the portions, e, of the cutting edge of the knife engages
therewith; so that when cutting with this knife, the blade is cutting at two
different angles; viz.:-parallel with, and at an angle to the cutting edge of the
blade, when the knife is being drawn towards, or pushed from the operator, this
construction forms a knife blade, which readily and easily cuts through the bread,
and hardest crust, with very little pressure, and forming very little if any crumbs,
and this operation is intended to be performed with the bread resting on a cutting
board or bread plate, in which case, the knife is operated away from the operator,

page_text: thereby completely preventing any possibility of injury to the latter, when the
knife is in operation.
These grooves, g, in one side of the blade are formed for the purpose of relieving
the bread from the rubbing of the blade at the cutting edge when in operation,
which almost completely if not altogether prevents the rubbing off, of portions of,
and the formation of bread crumbs, from this cause, at the same time, by forming
these grooves, g, the process of sharpening the cutting breasts, s, is facilitated.
This construction of a knife-is-particularly adapted for cutting loaves into slices,
at the same time, we intend it to be used as a bread or meat knife or saw, and used
for cutting bread, meat, and fruits or vegetables of any kind.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is:-
As an article of manufacture, a handle, H, in combination with a blade, B,
preferably sharpened on one side, and having notches, n, formed at intervals apart,
in the cutting edge thereof, and portions, e, of the cutting edge between said
notches, n, the sides of which notches are sharpened, and form breasts or angular
cutting edges, 3, and the grooves, g, formed in one side of the blade only, and on a
line with the notches, n, and extending back a short distance from the cutting edge
of said blade, substantially as shown and described, and for the purpose specified.
