others as 1, the said Charles Schmalcalder, my executors, administrators, or
assigns, should at any time agree with, and no others, from time to time
and at all times thenafter during the term of years therein expressed
should and lawfully make, use, exercise, and vend my said Invention within

said Charles Schmalcalder, my exors, admors, and assigns, or any of us,
should in our discretion seem meet, and I, the said Charles Schmalcalder,
my executors, administrators, and assigns, should and lawfully might have
and enjoy the whole profit, benefit, commodity, and advantage, from time to
time coming, growing, accruing, and arising by means of the said Invention,

and enjoy the said licence, powers, priviledges, and advantages therein-before
granted or mentioned to be granted unto me, the said Charles Schmalcalder,
my cfors, administrators, and assigns, for and during and unto the full end
and term of fourteen years from the date of the said Letters Patent next and
immediately ensuing, and fully to be compleat and ended. according to the
Statute in that case made and provided; and in which Letters Patent is
contained a proviso that ii 1. the said Charles Schmalcalder, should not par-
ticularly describe and ascertain the nature of my said Invention, and in what
manner the same is to be performed, by an instrument in writing under my
hand and scal. and cause the same to be enrolled in His Majesty's High
Court of Chancery within one calendar month next and immediately after the
date of the said Letters Patent, then the said Letters Patent, and all and all
liberty's and advantages whatsoever thereby, should cease, determine, and
become void, any thing therein-before contained to the contrary thereof in

page_text: anywise notwithstanding, as in and by the said Letters Patent, relation being
thereunto had, will more fully and at large appear.
NOW KNOW YE, that I, the said Charles Schmalcalder, in compliance
with the said proviso, do hereby describe and ascertain the nature of my
Invention, and the manner in which the said Invention is to be constructed,
applied, and worked, is in manner and form herein-after described with
reference to the Figure, Plate, or Plan thereof hereunto annext (that is
to say):-
My Invention consists in constructing, applying, and working the following
machine, which, for the sake of distinction, I call a delineator, coppier, propor-
tionometer, consisting of a hollow rod a, Figure 1 and 2, (the latter forming
a section of the instrument) screw'd together, and from two to twelve feet, or
still longer, chiefly made of copper or brass, sometimes wood, or any metal
applicable. The one end b carries a fine steel tracer c, made to slide out and
in, and to be fastened by the mill'd-head screw'd, the other end of the rod
having likewise a round hole to take up either a steel point, blacklead pencil,
or any other metallic point, which may be fastened therein by a mill'd-head
screw like d. 1 fix a tube in a ball e about ten inches long, and in diameter
sufficiently large to allow the rod a to slide easily and without shake in it;
the ball with this tube is moveable between two half sockets, forming together
what is commonly called a ball and socket. F is a frame made of wood, and
about two and a half or three feet long (this length depends from the length of
Through the sides of the frames
the rod), and is supported by two brackets.
F are holes, at certain distances, corresponding with the marks on the rod a;
hence it is evident, that in copying any original, supposing to the size of
,,,,&c., the swing board and the clamp screw h must be transplanted
to the different holes and divisions corresponding. The paper, ivory, or
copper, &c. is fastened upon the swinging board, either by screws or by a
brass frame form'd of two flat pieces of brass join'd together at the end by
hinges, and having on the other end two buttons to fasten the paper between.
In the uppermost of this plate an opening is made to allow the point to mark
upon the paper. The edges of this frame form and slide in a dove-tail move-
able upon the swinging board, and kept in the proper situation by the spring i.
On the back of the board is affixed a weight with a hook , to which is
attached a string forming a pulley, serving to prevent the point from acting
upon the paper when not wanted. The machine is fixed either to a partition
in any room. or to any piece of wood portable, and so constructed as to be
easily fixed upwright with a scrow clamp upon a table or any other stand.

page_text: The instrument is perfect, first, when all the parts are firmly connected and
without fluctuation: 2d, when the ball and socket are truly circular and move
easy: 3rd, when the rod passes truly through the centre of the ball: 4th.
when the rod is perfectly straight (the diameter of the rod is from half an
inch to two inches and upwards, according to the length); 5th, and lastly, in
turning the rod round in the sockets, the tracer and point in the two ends of
the rod must remain in the centre, to obtain which sometimes an adjustment
with four screws, Figure 3. is required. a. Figure 3. is a steel point; b, the
tracer and c, the form of the cutters used for cutting out the profiles. d is
a hook hanging on a string for the rod to rest in.
Having thus far mentioned and described the construction of this my new
Invention, so as, to the best of my belief and knowledge, will enable every
person or persons to work and make an instrument accordingly. I proceed
Lo describe the use of the delineator:-
First, for taking profiles, previous to the fixing of the instrument against
the partition, you must have taken the height from the bottom to the middle of
the face of a person sitting upon a chair; and that height, transfered upon the
partition. is the place where the sockets are to be fastened. Let the person's
head rest against a piece of wood lined with leather; begin tracing at the back,
and in tracing observe the screw d to form a right angle with every part of the
face in passing over it, in consequence whereof you must turn the rod round
in the socket, and the cutter e previously fixed in the rod will cut out the
profiles.
Secondly, when copy and trace pictures, landscapes, &c., I hang the
original up so as to swing, and fix either paper, ivory, copper, &c. upon the
swinging board, then placing the tracer to the edge of the original picture,
then begin following and tracing over every part of the picture, by which
means receive a copy upon the copper, ivory, &c. reversely. From the
construction of the instrument it is evident that the original as well as the
ivory. &c. must swing, on account of the tracer in the rod describing a circle
from the centre of the ball. Supposing, however, a picture of the size of
eight. feet square is to be copied upon copper to half the original size by a rud
of about ten feet, or even eight feet, long, the circle described by the rod or
trace from the centre of the ball would not deviate above one foot from the
plane surface of the picture; hence, this would be the space the original would
swing during the operation, and the swinging board in proportion.
Thirdly, and lastly, when I copy from nature, landscapes or whatever
obiect exposes itself to view, the machine remains as during the operation

page_text: above, and looking along the rod, keeping the tracer and the perpendicular
object together in sight, I follow and trace the latter, and receive a copy as
above.
In witness whereof, I, the said Charles Schmalcalder, have hereunto set
my hand and seal, the Twenty-ninth day of December, in the forty-
seventh year of the reign of His Majesty King George the Third, and
in the year of our Lord One thousand eight hundred and six.
