An Improved Device for Cleaning Knives or the like.
I, OTTO STEIN, of the Firm of Gebrueder Stein, of Barmen, in the Empire of
Germany, Manufacturers, do hereby declare the nature of this invention to be as
follows:
This invention relates to an improved device for cleaning knives and is shown
in the annexed drawing in Figs. 1, 2 and 3 in plan view, longitudinal section and
side view respectively.
This device consists of the two bars a provided with handles and hinged to one
another by means of an intermediary piece b. The distance of the two bars a
from one another corresponds to the length of this intermediary piece b and the
thickness of the intermediary layers must be chosen correspondingly, so that the
latter lightly touch one another and can be pressed strongly against one another
by pressing the two bars together by means of the handles. In order to make the
bars a
as light as possible, they are slotted as at a¹. On the inner side
of each bar is placed a thin flat spring c of the width of the bar having on both
ends several pins c¹. On each flat spring c lies an elastic under layer d of felt
india rubber or the like, which is fixed on the flat spring by means of the cleaning
strip e, the two ends of which extend over the points c¹ provided on the ends of
the flat springs c. The cleaning strips. may consist of emery cloth, emery paper
or the like.
For fastening the flat springs c carrying the cleaning strips e and the elastic
under layers each bar a has on the inner side the projections a³, a³ of which the
latter has an adjusting screws.
C
After the elastic under layer d with the cleaning strip e has been laid on the
flat spring the ends of the cleaning strips are passed round the ends of the springs,
and the points c¹ are pressed into the cleaning strip and fix the same with the
under layer d on the flat spring. In order to fix the latter on the bars a the flat
spring g after having been bent a little is slid under the projections a³ a2 and
the screws s and the screws are screwed up a little after the flat spring is again
straight. The flat spring thus fastened with the under layer d and cleaning
stripe on the holder.
The knife or the like to be cleaned is slid between the cleaning strips lying
against one another and is moved to and fro in the longitudinal direction of the
cleaning device. By pressing the two bars a more or less together it is possible
to regulate the friction on the cleaning strips.
By means of this arrangement the friction is equal over the whole surface.

Germany, Manufacturers, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to an improved device for cleaning knives, and is shown
in the annexed drawing, in,
Figs. 1, 2 and 3 in plan view, longitudinal section, and side view respectively.
This device consists of the two bars a, provided with handles and hinged to one
another by means of an intermediary piece b. The distance of the two bars a
from one another corresponds to the length of this intermediary piece band the
thickness of the intermediary layers must be chosen correspondingly, so that the
latter lightly touch one another and can be pressed strongly against one another
by pressing the two bars together by means of the handles. In order to make the
bars a
as light as possible, they are slotted as at a¹. On the inner side
of each bar is placed a thin flat spring of the width of the bar having on both
ends several pins c¹. On each flat spring c lies an elastic under-layer of felt,
india-rubber, or the like, which is fixed on the flat spring by means of the cleaning
strip e, the two ends of which extend over the points c¹ provided on the ends of
the flat springs c. The cleaning strips may consist of emery cloth, emery-paper,
or the like.
For fastening the flat springs carrying the cleaning strips e and the elastic
under-layers d each bar a has on the inner side the projections a² a³ of which the
latter has an adjusting screw s.
After the elastic under layer d with the cleaning strip e has been laid on the
flat spring e, the ends of the cleaning strips are passed round the ends of the springs,
and the points c¹ are pressed into the cleaning strip and fix the same with the
under-layer d on the flat spring. In order to fix the latter on the bars a the flat
spring, after having been bent a little, is slid under the projections a³, a² and
the screws s and the screws are screwed up a little after the flat spring is again
straight. The flat spring is thus fastened with the under layer d and cleaning
strip e on the holder.
The knife, or the like, to be cleaned is slid between the cleaning strips, lying
against one another and is moved to and fro in the longitudinal direction of the
cleaning device. By pressing the two bars a more or less together it is possible
to regulate the friction on the cleaning strips.
By means of this arrangement the friction is equal over the whole surface.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is:
1. The device for cleaning knives and the like, adapted to be operated substan-
tially as set forth.
2. The device for cleaning knives and the like having means for holding remov-
able cleaning strips attached substantially as illustrated and described, the said
device being adapted to be operated substantially as set forth.
