page_text: LETTERS PATENT to John Henry Johnson, of 17, Lincoln's Inn Fields,
in the County of Middlesex, Gentleman, for the Invention of
“An Improved Combined Pencil aND ERASER."—Ą communication from
abroad by Joseph Reckendorfer, of the City, County, and State of
New York. United States America.
PROVISIONAL SPECIFICATION left by the said John Henry Johnson
at the Office of the Commissioners of Patents, with his Petition
on the 6th February 1873.
I, JOHN HENRY JOHNSON, of No. 47, Lincoln's Inn Fields, in the
County of Middlesex, Gentleman, do hereby declare the nature of the said
Invention for "AN IMPROVED COMBINED PENCIL AND ERASER," a communi-
cation to me from abroad by Joseph Reckendorfer, of the City, County,
and State of New York, United States America, to be as follows:—
This Invention relates to lead or crayon pencils, having an india-
rubber or other like craser at one end of the same, and consists essen-
tially in making a wooden-cased lead pencil or crayon of equal or
practically equal diameter throughout the entire length, into one portion
of the length of which I insert and cement in the usual manner the lead

page_text: or crayon, whilst within the remaining portion from the opposite end of
the said wooden case or covering I form a cylindrical chamber for the
reception of a cylindrical piece of india-rubber or other like craser, which
may be cemented in its place like the lead or crayon, the same wooden
case serving to encrease both the lead or crayon and the cylindrical piece
of eraser. By this mode of construction I avoid any unsightly enlarge-
ment of the wooden case necessary for strengthening the same at the
part containing the eraser, whilst I at the same time avoid the splitting
of the case round the eraser, which has heretofore occurred by reason of
the chamber for the eraser and the piece of craser itself being hitherto
mado of a rectangular cross section, which section of necessity involves
the existance of weak portions in the wooden case at the several angles
or corners of the said rectangular chamber.
I further propose, according to this Invention, to reduce the pro-
truding part of the crasing material to a neat point by grinding or
otherwise before supplying the article to the market.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Henry Johnson in the Great Seal Patent
Office on the 5th August 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of
Middlesex, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of February, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-sixth
year of Her reign, did, for Herself, Her leirs and successors, give
and grant unto me, the said John Henry Johnson, Her special license
that I, the said John Henry Johnson, my executors, administrators, and
assigns, or such others as I, the said John Henry Johnson, my executors,
administrators, or assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, usc, exercise, and vend,
within the United Kingdom of Great Britain nud Ireland, the Channel
Islands, and Isle of Man, an Invention for "AN IMPROVED COMBINED
PENCIL AND ERASER," a communication to me from abroad by Joseph

page_text: Reckendorfer, of the City, County, and State of New York, United
States of America, upon the condition (amongst others) that I, the said
John Henry Johnson, my executors or administrators, by an instrument
in writing under my hand and scal, should particularly describe and
ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Henry Jolinson, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
Drawings, and to the letters and figures marked thereon, that is to
say:-
The said Invention relates to lead or crayon pencils having an india-
rubber or other like eraser at one end of the same, and consists essen-
tially in making a wooden-cased lead pencil or crayon of equal or
practically equal diameter throughout the entire length, into one portion
of the length of which I insert and cement in the usual manuer the
lead or crayon, whilst within the remaining portion, from the opposite
end of the said wooden case or covering, I form a cylindrical chamber
for the reception of a cylindrical piece of india-rubber or other like
crasure, which may be cemented in its place like the lead or crayon, the
same wooden case serving to enclose both the lead or crayon and the
cylindrical piece of craser. By this modo of construction I avoid any
unsightly enlargement of the wooden case necessary for strengthening
the same at the part containing the eraser, whilst I at the same time
avoid the splitting of the case round the eraser, which has heretoforo
occurred by reason of the chamber for the craser and the piece of craser
itself being hitherto made of a rectangular cross section, which section
of necessity involves the existence of weak portions in the wooden case
at the several angles or corners of the said rectangular chamber.
I further propose, according to this Invention, to reduce the pro-
truding part of the erasing material to a neat point by grinding or
otherwise before supplying the article to the market.
And in order that the said Invention may be fully understood I shall
now proceed more particularly to describe the same, and for that purpose

page_text: shall refer to the several Figures on the annexed Sheet of Drawings,
the same letters of reference indicating corresponding parts in all the
Figures.
Figure I. of the Drawings annexed represents a perspective elevation
of the improved combined pencil or crayon and craser; Figure 2 is a
longitudinal section of the same; and Figure 3 is a transverse section
taken through the craser and that part of the wooden case which
encloses it.
a is the wooden case made in two halves longitudinally from end to
end as in tho usual manner; b is the lead or crayon enclosed therein;
and c is the craser which is of a cylindrical form, and is enclosed in a
cylindrical chamber in the end of the wooden case, and fixed therein by
cement or otherwise.
The craser and the end of the wooden case are pointed or reduced to
a conical form, as shown, by grinding or otherwise before supplying the
same to the market.
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used or
carried into effect, I would observe in conclusion that I do not claim the
use of a lead pencil with a piece of india-rubber or other crasing inaterial
attached to or inserted into one end thereof for the purpose of crasing
marks, but what I consider to be novel and original, and therefore
claim as the Invention secured to me by the herein-before in part recited
Letters Patent is, the combination of the lead or crayon and the india-
rubber or other crasing substanco in the holder or wooden case of a
drawing pencil, when the whole is constructed and arranged substan-
tially in the manner and for the purpose herein-before described and
illustrated by the Drawings annexed.
In witness whereof, I, the said John Henry Johnson, have to this
my Specification set my hand and seal, this Thirty-first day of a
July One thousand eight hundred and seventy-three.
