Year: 1876

page_text: LETTERS PATENT to William Howard, of Camden Town, in the County of
Middlesex, for the Invention of "IMPROVEMENTS IN INK ERASERS."
PROVISIONAL SPECIFICATION left by the said William Howard at the Office
of the Commissioners of Patents, on the 1st January 1876.
WILLIAM HOWARD, of Camden Town, in the County of Middlesex.
MENTS IN INK ERASERS.".
"IMPROVE-
This Invention relates to improvements in instruments for erasing or removing
ink or other marks from the surface of paper, parchment, or other materials. For
this purpose in placing of using the edge of a knife, sand, or emery paper, or com-
positions of india-rubber and other materials for abrading the surface I employ a
fine steel file of suitable form, which may be mounted in a holder.
The surface of the file employed for erasing is with advantage curved, and one or
both ends may be smooth and polished in order to rub down and smooth the
surface from which ink has been erased; or the file holder may be formed with a
smooth rubbing down surface, and also have a piece of india-rubber combined
therewith for cleaning paper and removing pencil or other marks therefrom.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said William Howard in the Great Seal Patent Office on the 30th June 1876.
WILLIAM HOWARD, of Camden Town, in the County of Middlesex.

into practice, I will proceed to describe the Drawing hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a plan and side view of an ink eraser constructed in accordence
with my Invention. a is the eraser mounted in the holder or handle b; one surface
of the eraser a is cut like a fine file, the other surface being smooth and polished
for the purpose of rubbing down and smoothing the surface of the paper after
erasures.
Figures 2 and 3 show other forms of erasures a made in accordence with my
Invention, mounted in holders b, having a piece of india-rubber c at one end, as
clearly shown in the Drawing.
Having thus described the nature of my Invention, and the manner of performing
or carrying the same into practice, what I claim is, the improved construction of
erasers or instruments for erasing ink or other marks from paper, parchment, or
other materials, substantially as herein described and represented in the Drawings
annexed.
In witness whereof, I, the said William Howard, have hereunto set my hand
