PROVISIONAL SPECIFICATION.
Improvements in Dough Notching Knives.
I, MARK DARE of No. 78 Cornwall Road, Lambeth, in the County of Surrey,
Baker, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in knives for notching dough.
In the case of dough made up in lengths of the same cross section as the size of
the piece to be sold, it has been customary to provide for the easy breaking off
from the length, of pieces of the proper size, to notch the said length transversely.
This has been done by a single blade, each cut producing one notch. The distances
between the notches have consequently been somewhat irregular, according to the
skill of the baker.
According to the present invention, the knife has many equidistant blades parallel
with each other, so that each cut shall make as many equidistant notches across the
length. The blades are made fast to a suitable handle. They may be single blades
rivetted by their tangs to a bar, which, in its turn, is made fast to a suitable handle
or the blades may be and handle may be stamped out of one piece of metal, each
blade being turned through an angle of 90°. Either method of manufacture, or
any other equivalent may be followed.

Improvements in Dough Notching Knives.
I, MARK DARE of No. 78 Cornwall Road, Lambeth, in the County of Surrey,
Baker, 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 knives for notching dough.
In the case of dough made up in lengths of the same cross section as the size of
the piece to be sold, it has been customary to provide for the easy breaking off
from the length, of pieces of the proper size, to notch the said length transversely.
This has been done by a single blade, each cut producing one notch. The distances
between the notches have consequently been somewhat irregular, according to the
skill of the baker.
According to the present invention, the knife has many equidistant blades parallel
with each other, so that each cut shall make as many equidistant notches across the
length. The blades are made fast to a suitable handle. They may be single blades
rivetted by their tangs to a bar, which, in its turn, is made fast to a suitable
handle, or the blades and handle may be stamped out of one piece of metal, each
blade being turned through an angle of 90°. Either method of manufacture, or
any other equivalent may be followed.

page_text: Referring to the accompanying figures:-
Figure 1 is a perspective view of an improved notching knife made according to
the first alternative method described above.
Figure 2 is a side elevation corresponding therewith.
Figure 3 is a perspective view of part of an improved notching knife made
according to the second alternative method described above.
Referring to Figures 1 and 2, a, a are the blades. They are uniform in size and
shape and stand in the knife at equal distances from each other their points in a
row and their edges in the same direction. is a metal bar to which the said blades
are made fast in the position above mentioned by having their tangs rivetted in it.
is the handle of the knife and the bar b is held fast to it by screws d. The shape
and material of the handle c as well as the shape of the bar d and the means by
which the latter is held to the former may be varied as may be desired..
The number of blades illustrated-six-is a convenient one but my invention
does not limit me to it.
The lines e, e indicate the plurality and parallelism of the notches which one
stroke of the improved knife.
Referring to Figure 3, the blades a¹ and the handle c are produced as already
described, by stamping them out of sheet metal and turning each blade through an
angle of 90°. There are no differences between the knife illustrated in Figures 1
and 2 and that illustrated in Figure 3, beyond those due to the respective process
of production. The positions of the knives with respect to each other and the
handle are not affected.
The invention does not limit me to rivetting the above mentioned tangs to the
bar they may be screwed into it or welded to it. The bar itself may be
dispensed with, the tangs being then inserted in the handle c and cemented or
rivetted thereto. But it is a feature of the present invention, that the blades a of
my improved notching knife, are held to the handle once for all-the construction
of it does not include, because it does not require, any joint between blade and
handle.
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 :-
The hereinbefore described combination of handle and plurality of blades held
rigidly thereto at distances apart dictated by the custom of the respective trade,
as and for the purpose set forth.
