in the County of Middlesex, 'Gentleman, för the Invention of
"IMPROVED SAND, GLASS, OR EMERY PAPER OR EMERY CLOTH."—A com-
munication from abroad by George Carpenter Taft, of Worcester,

Sealed the 25th July 1871, and dated the 28th February 1871.
PROVISIONAL SPECIFICATION left by the said John Henry Johnson
at the Office of the Commissioners of Patents, with his Petition,
on the 28th February 1871.
I, JOHN HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County
of Middlesex, Gentleman, do hereby declare the nature of the said Inven-.
tion for "IMPROved Sand, Glass, OR EMERY PAPER OR EMERY CLOTH,” a com-
munication from abroad by George Carpenter Taft, of Worcester, Massa-
chusetts, and Jacob Henry Armbruster, of Philadelphia, Pennsylvania,
United States of America, to be as follows:-
This Invention consists in the application of adhesive material to the
back of sand, glass, or emery paper or emery cloth. for. the purpose of

page_text: readily attaching the same to a strip of wood or other object, the sand or
emery paper thus prepared constituting an article of commerce which
will enable artisans to practice economy in the use of these indispensable
materials.
In using sand paper it is a common practice with carpenters, pattern
makers, and others to wrap a piece loosely round a strip of wood in order
to apply it evenly to the surface to be smoothed. In like manner it is a
common practice with machinists and other workers in metal to wrap a
strip of emery paper or emery cloth loosely round a file or other like
object prior to applying it to the surface to be polished. In both cases
the paper or cloth is rapidly worn away or torn and the surface removed
owing to the looseness of the wrapping. I afford a remedy for this rapid
destruction of the sand or emery paper by coating the back with gum,
glue, mucilage, or other equivalent cement, in the same manner as
postage and other stamps are treated, the sheets thus coated being sold
as articles of commerce, so that a strip cut from a sheet is in a condition
for immediate attachment to wood or other material, simply wetting the
gummed back of the strip and applying it to the wood under a slight
pressure being all that is necessary to effect the required adhesion.
Sand or emery paper or cloth will last much longer when cemented to
a strip of wood or other like object than when it is wrapped loosely to
the same; this Invention therefore affords the readiest means of effecting
the desired attachment and of exercising economy in the use of the
material.

SPECIFICATION in pursuance of the conditions of the Letters Patent, 2
filed by the said John Henry Johnson in the Great Scal Patent
Office on the 26th August 1871.
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 Twenty-eighth day of February, in the
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fourth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said John Henry Johnson, Her 3

page_text: 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,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
**IMPROVED SAND, Glass, OR EMERY PAPER OR EMERY CLOTH," a communication
from abroad by George Carpenter Taft, of Worcester, Massachusetts,
and Jacob Henry Armbruster, of Philadelphia, Pennsylvania, United
States of America, upon the condition (amongst others) that I, the
said John Henry Johnson, 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 immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said John Henry Johnson, 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, that is to say :—
'
The said Invention consists in the application of adhesive material to
the back of sand, glass, or emery paper or emery cloth for the purpose
of readily attaching the same to a strip of wood or other object, the sand
or emery paper thus prepared constituting an article of commerce which
will enable artisans to practice economy in the use of these indispensable
materials.
In using sand paper it is a common practice with carpenters, pattern
makers, and others to wrap a piece loosely round a strip of wood in order
to apply it evenly to the surface to be smoothed. In like manner it is
a common practice with machinists and other workers in metal to wrap
a strip of emery paper or emery cloth loosely round a file or other like
object prior to applying it to the surface to be polished. In both cases
thic paper or cloth is rapidly worn away or torn and the surface removed
owing to the looseness of the wrapping. I afford a remedy for this rapid
destruction of the sand or emery paper by coating the back with gum,
glue, mucilage, or other equivalent cement in the same manner as
postage and other stamps are treated, the sheets thus coated being sold

page_text: as articles of commerce, so that a strip cut from a sheet is in a condition
for immediate attachment to wood or other material, simply wetting the
gummed back of the strip and applying it to the wood under a slight
pressure being all that is necessary to effect the required adhesion.
Sand or emery paper or cloth will last much longer when cemented to 5
a strip of wood or other like object than when it is wrapped loosely
to the same; this Invention, therefore, affords the readiest means of
effecting the desired attachment and of exercising economy in the use
of the material.
Having now described and particularly ascertained the nature of the 1
said Invention, and the manner in which the same is or may be used
or carried into effect, I would observe in conclusion that 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 manufacture and use of sand, glass, or emery paper or emery
cloth rendered adhesive at the back, substantially as and for the purpose
lierein-before described.
In witness whereof, I, the said John Henry Johnson, have to
