A MACHINE OR ENGINE CONSTRUCTED ON SELF-MOVING PRINCIPLES
Year: 1779

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I JOHN
DIETRICK MÜLLER, of the Parish of Saint James, in the Liberty of Westminster,
in the County of Middlesex, Gentleman, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Sixteenth day of June, in the nineteenth year of His reign, did
give and grant unto me, the said John Dietrick Müller, His special lycence,
full power, sole priviledge and authority, that I, the said John Dietrick Müller,
my exors, admors, and assigns, should and lawfully might, during the term of
years therein expressed, make, use, exercise, and vend throughout that part of
Great Britain called England, the Dominion of Wales, and Town of Berwick-
upon-Tweed, and also in all His Majesty's Colonies and Plantations abroad, my
Invention of "A MACHINE OR ENGINE CONSTRUCTED ON SELF-MOVING PRINCIPLES;"
in which said recited Letters Patent is contained a proviso obliging me, the said
John Dietrick Müller, by writing under my hand and seal, to cause a particular
description of the nature of the said Invention, and in what manner the same
is to be performed, to be inrolled in His Majesty's High Court of Chancery
within four calender months after the date of the said recited Letters Patent,
as in and by the sd recited Letters Patent, and the Statute in that behalf made,
relation being thereunto respectively had, may more at large appear.
NOW KNOW YE, that in compliance with the said proviso, and in pur-
suance of the said Statute, I, the said John Dietrick Müller, do hereby
declare that my said Invention is composed, made, and performed, in manner
herein-after mentioned, that is to say :-

page_text: My said machine or engine consists of the following parts, and depends on
the following principals, viz, a double wheel, consisting of two frames, fixed on
and at right angles to an axis, moving on and supported by two pivots or
gudgeons; the places of each of these wheels or frames thus placed parallel
to each other, and having each two or more apertures corresponding with each
other, in such manner that the axis of a cylinder passing thro' the corre-
sponding aperture in both frames shall be exactly paralled to the axis on which
the wheels or frames turn. The internal surface of these apertures are smooth,
and truly circular, and bear to the whole circumference of the wheele or frame
the same proportion that is represented by the Figure hereunto or hereunder
annexed, marked No. 1. The distances of the internal surface of these wheels
or frames may be more or less at pleasure, as may also the diametor of the
wheels or frame, according to the intended power of the machine. Each
aperture has belonging to it an oblong box of the shape and proportion repre-
sented in the Figure marked No. 2; this box has connected to it two cylindric
pieces, so fixed to it that the axis of both may lie in the same streight line, and
at right angles to the sides of the box; these cylinders are each exactly half
the diameter of the apertures in the wheels or frames, and roll on the internal
surface thereof, serving as an axis for the oblong boxes to turn upon, and
having teeth or trundles to run, take, or act into other teeth formed on the
sides or external surface of the apertures, as represented in Figure marked
No. 3. In order that those cylinders may constantly keep a position truly paralled
to the axis of the wheels or frames, and to prevent the circumference of the
cylinders from slipping or sliding on the internal circumference of the apertures
in which they roll, each of these oblong boxes have each of their opposit
sides to which the axis or cylindric pieces are fixed perferated with three holes
of an oval shape, and bearing to each other the respective possition represented
in Figure (No. 2) hereunto annexed; and to each of these holes or oval
openings belongs a weight of the shap represented in Figures 4, 5, 6, having
two cylindric parts exactly equal to each other that may roll on the internal
circumference of these oval openings or holes as the oblong box in which they
are contained turns on its axis. It is evident from the possition of these oval
holes, that when the oblong box in which they are placed comes, or is in a
perpendicular position, that the weights which move in them will roll further
from the center, so as forcible to bring the oblong box to an inclined position,
and by that means the teeth or trundles on its cylindric axis will act on
the teeth which belong to the external surface of the apertures in the
wheele or frame, in a manner similar to progressive steps of a man acting
in the wheel of a crane, and thus the powers which are generated in any

page_text: machine depend upon the exact formation and relative positions of these
oval holes in the oblong boxes, & also the relative positions of the oblong boxes
in the apertures, which are severally and truly represented in Figure No. 1.
The exact proportion of the several parts may be had by a reference to the
annexed scale; the scale is formed by dividing the full extent of the diameter of
the intended wheel or frame into twelve equal parts, which may be called
modules, and each of these, being subdivided into twelve parts, may be called
minutes, and thus is a universal scale formed for any size. The framing and
external appearance of the machine may be varied according to the judgement
and fancy of the artist without loosing the effect; and it may be made of wood,
iron, steel, brass, or any other mettal or material that may be judged fit for the
purpose, or that may best answer the purposes of strength, durability, and
cheapness.
In witness whereof, I have hereunto set my hand and seal, this Fifteenth
day of October, in the year of our Lord One thousand seven hundred
and seventy-nine.
THO HANDLEY.
JOHN SAVAGE.
AND BE IT REMEMBERED, that on the Fifteenth day of October, in
the year of our Lord 1779, the aforesaid John Dietrick Müller came before
our said Lord the King in His Chancery, and acknowledged the Specifi-
cation aforesaid, and all and every thing therein contained and specified, in form
above written. And also the Specification aforesaid was stampt according
to the tenor of the Statute made in the sixth year of the reign of the late
King and Queen W and Mary of England, and so forth, and in the seventeenth
year of the reign of His Maty King George the Third.
Inrolled the Sixteenth day of October, in the year of our Lord One thou-
send seven hundred and seventy-nine
