CERTAIN IMPROVEMENTS APPLICABLE TO SKETCHING, DRAWING, OR DELINEATING, WHICH I INTEND TO DENOMINATE PARLOUR'S SKETCHING CASE
Year: 1836

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
PARLOUR, of Addiscombe Road, Croydon, in the County of Surrey, Gentleman,
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 Thirtieth day of March, in the sixth year of His
reign, did, for Himself, His heirs and successors, give and grant unto me, the
said Samuel Parlour, His especial licence, full power, sole privilege and
authority, that I; the said Samuel Parlour, my exors, adfñors, and assigns, or
such others as I, the said Samuel Parlour, my 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, my Invention of "CERTAIN IMPROVEMENTS APPLICABLE TO
SKETCHING, DRAWING, OR DELINEATING, WHICH I INTEND TO DENOMINATE PARLOUR'S
SKETCHING CASE;" in which said Letters Patent is contained a proviso, that I,
the said Samuel Parlour, shall cause a particular description of the nature of
my 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 in part recited Letters
Patent, as in and by the same, reference being thereunto had, will more fully
and at large appear.

page_text: Figure 1 represents a side view of an apparatus arranged and combined
according to my improvements, such apparatus being affixed to a portfolio or
case; Figure 2 is a plan of the portfolio or case; Figures 3, 4, 5, and 6 shew
detached views of the several parts, the arrangement of which, and their
application to this particular purpose constitute my Invention. In each of
a is a hollow stem or
these Figures the same letters indicate similar parts.
standard, which moves stiffly on the hinge b, which is affixed to the case or
portfolio by a screw, which enters one of the holes c, c, in the portfolio or case.
At the upper part of the standard or stem a there is formed a screw, on
which the nut d screws, and the upper part of the standard being split, the
screwing down of the nut d will cause the upper end of the standard to press
on and retain the stem e in any position to which it may be placed, the stem e
being capable of sliding in the stem a. By this means the stem or standard
which supports and carries the parts hereafter described can be adjusted to the
length and position desired. fis a small reflector, of glass or other suitable
material, which is affixed in a frame, as is clearly shown in plan and side view
in Figure 3. This reflector consists of a square plate of glass, silvered on the
back side, and retained in the frame by the screw g. This reflector is
suspended on an axis h, and is capable of adjustment by means of a short
screw and nut i, the screw passing through a slit or opening; formed in the
frame k, by which means the reflector can be set at any desired angle with
respect to the other parts, in order to sketch any object it it desired to draw.
kis a frame, the shape and construction of which will be evident on examining
Figures 1 and 4. The frame k moving on an axis at 1, as is clearly shown.
m is a frame, shown separately at Figure 5, which represents a side view and
plan of that frame. In the frame m is affixed a square piece of brown or
other colored glass. The frame m moves stiffly on a pin or axis at the upper
part of the standard, as is clearly shewn. n is a frame, containing a lense to
suit the sight of the person using the instrument, and to clear the point of the
pencil when sketching; and it will be seen that by means of the screw o the
frame a may be set at and retained to any desired angle.

page_text: Having thus described the nature of my Invention, and the manner of
combining the various parts, I will describe the manner of using the same.
Having set the various frames and glasses, as is shewn at Figure 1, in such
manner as to produce the object it is desired to sketch to appear as if it were
reflected on the plane, below the eye of the person using the apparatus looking
through the instrument in the direction of the arrow, this adjustment will
be quickly obtained; and correctly to adjust the instrument, the apparent
reflection of a perpendicular line of an object on the plane below, should be
parallel to the sides of the portfolio or case. The object may then be sketched
with facility. The hand, having a pencil, can be seen clearly by the eye on look-
ing through the instrument, and hence as the object appears to the eye to be
reflected on the plane below, if such plane be a sheet of paper placed on the
portfolio or case, the sketch desired will be obtained.
In witness whereof, I, the said Samuel Parlour, have hereunto set my
hand and seal, this Twenty-eighth day of September, in the year of our
Lord One thousand eight hundred and thirty-six.
SAMUEL PARLOUR.
