at the Office of the Commissioners of Patents, with his Petition
and Declaration, on the 15th March 1873, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
JANSEN HAIGHT, of New York, in the State of New York, in the United
States of America, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENT IN
ARTISTS' SCRAPERS," and have petitioned Her Majesty to grant unto me,
O my executors, administrators, and assigns, Her Royal Letters Patent
for the same, and have made solemn Declaration that I am the true and
first Inventor thereof.

page_text: NOW KNOW YOU, that I, the said Henry Jansen Haight, do hereby
declare that the following Complete Specification under my hand and
seal, fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed, in and by the following
statement:-

This Invention relates to a certain tool or implement which I
denominate the "artists' Scraper," and consists of a steel plate of
peculiar form and shape having a smaller moveable index plate of
suitable size attached, capable of moving laterally on a pivot, and by the
adjustment of which the width of a sharpened edge on the plate may be 1
regulated. Other sharpened edges of various width are arranged on
this plate for the purpose of scraping off the paint from the outer edge
or border of the canvas, or of scraping and cleaning the pallet.
In order to explain this Invention as completely as possible, I now
proceed to describe the best means I am acquainted with for carrying the 1
same into practical effect, reference being had to the accompanying
Sheet of Drawings hereunto annexed, and to the letters of reference
marked thereon.
Figure I. represents a top view of my artist's scraper embodying my
Invention; Figures II. III. and IV. represent different views, shewing 20
the application and use of the scraper. This scraper consists of a steel
plate A, the general form and shape of which being shown in Fig. I.
The dimensions not being more than one sixteenth part of an inch in
thickness, and from one and one half to two inches in breadth in its
broadest part, and from six to seven inches in length. Upon this 2
plate A a smaller moveable index plate J of metal, oval in form, and of
suitable size and thickness is attached, capable to be moved laterally on
a pivot K (see Fig. I.)
The letters c, c, c, c, represent a serrated edge, the several serratures
being sharpened and graduated in length from one half inch to one and 30
one half inch respectively. The letter m also represents a sharpened edge
with a graduated scale of nine sixteenth parts of an inch cut upon the
surface, by means of which and by an adjustment of the index plate J
any desired width of the sharpened edge m may be obtained. These
sharpened edges c, c, c, c, and m, above referred to are intended to be used 3
in scraping off the paint from the outer edge or border of canvas
painted upon, in order to obtain a clean surface or border of
any desired

page_text: width surrounding a picture or painting, as represented at b, b, in
Fig. II., and at d, d, Fig. III.
The sharpened edges p, p, p, on the scraper A are intended to be used
for the purpose of scraping and cleaning the pallet as represented in
Fig. IV.
Having now fully described and set forth my Invention and the
manner in which the same is or may be used, I hereby declare that
what I claim as my Invention and desire to secure by Letters Patent
is, the artists' scraper A provided with the sharpened edges p, p, p,
and m, as above described, and also the serrated and sharpened
edges c, c, c, c, with the moveable oval shaped metallic index plate J, in
combination with the graduated scale m, as above described and shown
in the Drawing.
In witness whereof, I, the said Henry Jansen Haight have here-
unto set my hand and seal, this Twenty-eighth day of February,
in the year of our Lord One thousand eight hundred and seventy-
three.
