Year: 1881

page_text: LETTERS PATENT to Henry Charles de Berenger, of 7, Sinclair Road, West
Kensington, County of Middlesex, Gentleman, for an Invention of "IMPROVE-
MENTS IN THE MANUFACTURE OF KNIFE-BOARDS.'
PROVISIONAL SPECIFICATION left by the said Henry Charles de Berenger
at the Office of the Commissioners of Patents on the 27th October 1881.
HENRY CHARLES DE BERENGER, of 7, Sinclair Road, West Kensington, County
of Middlesex, Gentleman. IMPROVEMENTS IN THE MANUFACTURE OF KNIFE-
BOARDS.'
"
I construct knifeboards of wood or any other material covered with leather,
kamptulicon, linoleum, or any other tough substance or composition, and perforate
such covering with a large number of holes of a round shape, a star pattern, or any
other shape.
These holes are to be filled up with a paste made of emery powder, brickdust,
or any of the powders usually taken for cleaning and polishing knives, mixed with
gum, oil, treacle, or any other binding medium, or the holes inay be simply filled
up with any dry polishing powder.
The object of this Invention is to prevent the great waste of polishing powder,
as the holes if once filled with polishing paste will very seldom require refilling,
and will keep the knifeboard supplied with a polishing material until the covering
is worn off; the knifeboard can be hung up or stood up after use without losing the
paste. If the holes are filled up with loose knifepowder instead of paste a great
saving in powder will be effected, but the paste is preferable. I find holes of
three sixteenth of an inch diameter and one quarter of an inch apart most suitable
for my purpose.
Having thus described the nature of my Invention and the manner of performing
the same, I would have it understood that I claim the manufacture of knifeboards
having a perforated covering to hold polishing paste or powder.

I construct knifeboards of wood or any other material covered with leather,
kamptulicon, linoleum, or any other tough substance or composition, and perforate
such covering with a large number of holes of a round shape or star pattern, or any
other shape. These holes are to be filled up with a paste or composition made of
emery powder, brickdust, or any of the powders usually taken for cleaning and
polishing knives; as a binding medium for this paste can be used, gum, glue, oil,
treacle, or similar material. Instead of such composition or paste the holes may
be filled up with the dry polishing powder. The object of this Invention is to
prevent the great waste of polishing powder, as the holes if once filled with
polishing paste will very seldom require refilling, and will keep the knifeboard
supplied with a polishing material until the covering is worn off, a further
advantage is the_great_cleanliness in use, there being no dust from the knifeboard,
which can be hung up or stood up after use without losing the polishing paste.
I find holes of 3/1 diameter and 1/4 to 3/ apart from each other most suitable
for my purpose; it is advisable to perforate the leather or other covering before it
is glued on to the board.
Having thus described the nature of my Invention and the manner of performing
the same, I would have it understood that I claim the manufacture of knifeboards
having a perforated covering to hold polishing paste or powder.
In witness whereof, I, the said Henry Charles de Berenger, have hereunto set
my hand and seal, the Twenty seventh day of April, in the year of our Lord
One thousand eight hundred and eighty two.
