page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ROBERT
BURTON COOPER, of Battersea Fields, in the County of Surry, Esquire, and
GEORGE FREDERICK ECKSTEIN, of High Holborn, in the County of Middlesex,
Ironmonger, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twelfth day of October, in the fourth year of His reign,
did, for Himself, His heirs and successors, give and grant unto us, the said
Robert Burton Cooper and George Frederick Eckstein, His especial licence,
full power, sole privilege and authority, that we, the said Robert Burton
Cooper and George Frederick Eckstein, our exors, adñiors, and assigns, or
such others as we, the said Robert Burton Cooper, our exors, admors, or
assigns, should at any time agree with, and no others, from time to time and
at all times during the term of years therein expressed, should and lawfully
might make, use, exercise, and vend, within England, Wales, and the Town
of Berwick-upon-Tweed, our Invention of "AN INSTRUMENT OR APPARATUS
POR POINTING PENCILS, AND CERTAIN OTHER PURPOSES;" in which said Letters
Patent is contained a proviso, that we, the said Robert Burton Cooper and
George Frederick Eckstein, or one of us, shall cause a particular description
of the nature of our said Invention, and in what manner the same is to be
performed, to be inrolled in. His said Majesty's High Court of Chancery
within six calendar months next and immediately after the date of the said

page_text: in part recited Letters Patent, as in and by the same, reference being there-
unto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
Robert Burton Cooper and George Frederick Eckstein, do hereby declare the
nature of our Invention, and the manner in which the same is to be performed,
are fully described and ascertained in and by the following description thereof,
reference being had to the Drawing hereunto annexed, and to the figures and
letters marked thereon, that is to say :-
Our Invention of an instrument or apparatus for pointing pencils, and
certain other purposes, consists in combining or forming an instrument or
apparatus by setting two files, or other sufficiently hard and rough surfaces,
at an angle to each other, and thus leaving a longitudinal, concave, angular
space between them, which instrument or apparatus, so formed, may be
constructed separately, or may be attached to other instruments, according to
the purpose to which it is to be applied.
DESCRIPTION OF THE DRAWING.
Figure 1 represents the instrument or apparatus separate, set in a frame;
a, a, being two files, set at right angles to each other, in a frame b of wood,
tortoise shell, metal, or other suitable substance, the two files a, a, being
affixed by cement or otherwise. This Figure shews our Invention in the most
simple form; we will therefore proceed to describe the manner of using the
same Supposing it is intended to point a black lead or other pencil, the
same is to be rubbed backwards and forwards with a very slight degree of
pressure in the position shown by the pencil c, continuing to turn it round in
order that all parts may be equally reduced by the files. By this means a
very sharp point will be obtained, and the wood part of the pencil reduced to
a long and even cone to the extent required. Now, it will be evident from
the above description that this instrument would be equally useful in pointing
holders for pens and hair pencils or brushes, and the stilletoes of ladies' work-
boxes, particularly such as are made of ivory, mother-o'-pearl, or of hard
woods, and by making the instrument to the proper size and roughness it
would be found useful in rasping or removing the ends of leaden or other
metal pipes, and producing a concave end thereto in order to prepare them for
making a joint by soldering; and it will be further evident that this instru-
ment may be combined in a variety of ways with other instruments. At the
same time it will be desirable to give some examples, that our Invention may
be most fully understood.

page_text: Figure 2 represents slate, having one of our instruments let into the
frame, by which the slate pencil may from time to time be pointed as it is
worn by use. Figure 3 shews the back of a knife; the two springs a, a,
(which act on the blades) are formed into files or rough surfaces at an
angle to each other, by which points may be made as before described.
Figure 4 is a plan, and Figure 5 is an end view in section, of two cir-
cular files or rough surfaces a, a, turning on axes in the frame b, for it will
be evident that an angle suited to the purpose will be formed between two
circular files; but this construction is more expensive. In some instances, in
place of forming the angle by means of two files, we have formed them on
one flat piece of metal, and bending them into an instrument having longi-
tudinally an angle with roughed surfaces similar to those above described, and
afford all the advantages of two files.
Having now described the nature of our Invention, and the manner of
constructing and using the same, we would remark that we are aware that
instruments have been before made by the intersection or crossing of files for
the purpose of sharpening knives and other instruments, but in these instances
the files are placed alternately, leaving an open space opposite each file. Now
it will be evident that such an instrument would not be suitable to accomplish
the object of our Invention, nor do we claim the producing an instrument or
apparatus made up of intersecting files leaving open spaces opposite to each
file, our instrument or apparatus requiring that the two surfaces by which the
angular space is formed should be continuous and opposite each other; and
we would have it understood that we do not confine ourselves to any particular
material for making the files or rough surfaces, as it will be readily understood
that a great variety of substances may be used, though in most instances we
prefer that they should be files made of steel; and lastly, we would have it
understood, that what we claim as our Invention is, the combining of files or
other sufficiently hard and rough surfaces, into an instrument or apparatus
having a continuous concave angular space or groove as above described, and
for the purposes aforesaid.
In witness whereof, we, the said Robert Burton Cooper and George
Frederick Eckstein, have hereunto set our hands and seals, this
Seventh day of April, in the year of our Lord One thousand eight
hundred and thirty-four.
