An Improved Attachment to Knives for Regulating the Thickness
of Substances Sliced.
I JOSEPH CLARE of 368 Waterloo Road, Burslem, Agent, 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 to an attachment to knives for cutting bacon, bread and
other substances, which will regulate the thickness of the slice and cause it to be
more evenly cut.
The device consists of a strip of metal preferably with its front edge turned
up or bevelled, fitted to the upper side of the knife by means of screws or
like means.
The strip is held at the required distance from the knife blade by means of small
blocks or distance pieces at the extreme ends through which pass the screw pins
fitting the parts together and fastened by suitable nuts. When the substance is
being cut, the slice will pass between the upper side of the blade and the regulating
strip, the latter bearing on it and thus preventing the blade from penetrating
beyond a certain depth, forming a guide by which the thickness of the slice is
regulated. If it is desired to cut thicker slices, small washers could be placed on
top of the blocks, or larger blocks could be employed.
In order that the invention may be more clearly understood, reference is had to
the accompanying drawings in which
Fig. 1 is a side elevation of the device fitted to the knife, Fig. 2 is a plan of the
same, and Fig. 3 is a cross section.
The blade A of the knife is perforated or slotted at each end, and the guiding
strip B is held at the required distance from the blade by the blocks or distance
pieces C at each end. Screw pins D with rivet heads are passed through the
perforations in the blade blocks and guiding strip, and small nuts d are employed
to fix the parts together. The edge 6 of the guiding strip as shown in cross section
is slightly turned up in order to allow of it passing over the material being cut
without danger of its impeding the course of the knife. The washers if they are
required can be placed between the block and guiding strip or knife blade raising
the strip off the blade.
If the strip be made strong the end fastening may be dispensed with and it may
be fixed only at the handle end. As shown the guiding strip can be easily removed
by unscrewing the nuts, when the knife is to be sharpened or cleaned.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is --
(1.) A guiding attachment for knives consisting of a metal strip fitted removably
to the blade of the knife at a known distance to regulate the thickness of slices
substantially as described.
(2.) A guiding attachment for knives consisting of a metal. strip fitted to the
blade by means of a screw pin, nut and block or distance piece at each end
substantially as and for the purposes specified.
(3.) The improved knife attachment constructed and operating substantially as
