BARBARA SARAH JANE MACKAY 6 Kingsley buildings Old Kent road in the
County of Surrey, Knife Cleaning Machine Manufacturer do hereby declare tho
nature of this invention and in what manner the same is to be performed, to he
particularly described and ascertained in and by the following statement:―
My Invention relates to improvements in the manufacture of a knife cleaning and
sharpening machine being in the form of a box about 9 inches long, 6 inches wide
and 4 inches deep, with one end open to allow the knife to be rubbed through
2 horizontal bars, covered with buff leather or other suitable material, and worked by
springs. To the upper bar a small box is attached for holding a supply of cleaning
powder which passes through an opening in the bottom of the box by the rubbing of
the knife. It cleans any sized table knife on both sides at once, giving a polish equal
to new, and a keen edge without injury to the knife. It combines effectiveness and
cleanliness, no powder being scattered or wasted. It is light and portable and can be
used in any apartment without causing dirt or annoyance, on the outside of the box I
fix a steel or knife sharpener, thus combining an effective knife cleaner and sharpener.
The combination as a whole being novel and usefull.
In order to make my invention better understood, I will now proceed to describe
the same by reference to the accompanying drawing on which Fig. A represents the
complete machine, about 9 inches long, 6 inches broad and 4 inches deep. The top B
is in the form of a sliding panel which is removeable so that a cloth or package of
cleaning powder can be put inside for use. The upper horizontal bar C, with powder
box D attached with slit in bottom for the powder to pass through, is let into a groove
in the left side of the box E, and secured by a spring of india rubber. The extended
end of the powder box projects through a cutting in the right side of the box F, and
is worked by a rubber ring attached to a knob on the outside of the box. When the
knife is passed through between the two horizontal bars, which are lined with buff
leather M for contact with the knife blade, the two springs give sufficiently to allow
the blade to pass through and receive a bright polish. On the lower part of the front
of the box is placed a piece of leather J for cleaning the shoulders of the knife; and
under the lower horizontal bar a piece of leather K for cleaning the back of the knife.
On the outside of the box is fixed the steel or knife sharpener L.
I wish it to be understood that I do not confine myself to the exact proportions as
specified, or materials as they may be varied if found necessary.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed, I declare that what I claim is.—
.I. The combination of materials hereinto defined and set forth, to be used as a knifo
cleaner and sharpener. The combination as a whole being novel and useful.
11. The manufacture and use of the improved knife cleaner and sharpener herein
mentioned substantially as described.
Dated this 5th day of March 1888.
