Improvements in Apparatus for Slicing Bread.
I, WILHELM EISNER, of Hohenlohenhütte, Upper Silesia, in the German Empire,
Publican, 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 a new or improved apparatus for slicing bread and is.
illustrated by the accompanying drawings to which reference will hereinafter be
made...
Figure 1 shews a sectional side view;
Figure 2, an end view; and
Figure 3, a cross section.
In the apparatus constructed according to these improvements, the loaf or other
form of bread to be sliced is placed in a box casing a of suitable shape and dimen-
sions which has a hinged upper part b. Toward the back end of the casing there
is arranged an internal transverse plate c, to the front of which there is connected
by the spiral spring d or other suitable elastic connection, the dished plate e.
The transverse plate acting as an abutment, the spring e tends to force the dished
plate forward, and, the bread being in front of and in contact with the dished plate,
is equally forced forward. The end of the loaf then protrudes through the open
front end of the casing, near which there is pivotted a knife f, which may be
ground along both edges so that it can be used for cutting on either or both sides.
The lower part of the plate c has formed upon or secured to it a saddle nut h, which
rides upon the screw g arranged longitudinally under the casing. On the front end
of the screw there is fixed a ratchet. wheel i with which there engages a pawl k,
pivotted on the knife f. If the knife therefore is moved in the direction indicated
by the arrow, a partial rotation is given to the screw 7 and the plate c is conse-
quently moved forward in the direction of the knife, the spring d being simul-
taneously compressed. In front of the opening in the case a there is a gauge
plate which can be adjusted as required for various thicknesses of slices. The
back surface of this plate is always in contact with the front surface of the loaf so
that this surface of the bread does not become dry when the apparatus is tempor-
arily out of use. The gauge plate is fixed upon the forward end of the slide
bolt m, which is capable of being moved longitudinally. A spiral spring n is
wound upon the bolt as indicated in such a manner that it tends to force the bolt
and gauge plate backwards. A ring o is fixed at the front end of the bolt whereby
the plate may be pulled forward from the front of the casing to a limited distance.
A recess is cut in the front end of the bolt into which there may be fitted one of
several semi-cylindrical distances pieces 9, which determines the thickness of the
slice to be cut. The distance piece is of such a size that it cannot pass through the
bolt hole and thus holds the gauge plate at a distance away from the front end of
the casing equal to its length. The gauge plate is further secured and guided by
means of a pin r and the adjustable spiral spring s thereon.
There is upon the knife f a fixed part or projection t, and upon the gauge plate 1

page_text: a corresponding fixed part u. The projections are so arranged that they come into
contact when the knife has almost passed through the bread. The stroke of the
knife being continued, the projections come into touch, and an inclined part on
one of them pushes the plate away from the bread so that when the bread is cut
right through, the severed slice is free to fall away from the apparatus. The slice
having been cut and separated, the knife may be moved backwards either by hand
or by means of a specially provided spring not shewn in the drawings. Then, as
soon as the projections t and u are out of contact, the spring d again presses the
cut surface of the loaf against the gauge plate, and the return stroke of the knife
being completed, all is ready for the severance, in the same manner, of another
slice.
When it is necessary to insert a loaf into the apparatus, the cover b is lifted
and the back plate c with the spring d and dished plate e are lifted so far that
the nut is free of the screw g, when they are transposed to the back of the
apparatus where they are replaced. The loaf is then placed in front of the dished
plate and the final adjustment can be made either by relifting the plate c and
pushing it forward or by reciprocating the knife so as to rotate the screw
the end of the loaf protrudes through the opening where the slices are cut. The
cover being closed the apparatus may be used as required.
until
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:
-
•
1. In apparatus for slicing bread, the combination and arrangement of the
back plates and spring cde, a nut and screw gh, a ratchet wheel on the screw
with which a pawl
the knife engages,
onl
a gauge plate l mounted
on a spring bolt m, a projection t on the knife, and a correspond-
ing projection u on the gauge plate, substantially as hereinbefore described
and as illustrated by the accompanying drawings.
2. An apparatus for slicing bread constructed arranged and operating substan-
tially as hereinbefore described with reference to the accompanying drawings.
