TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
FLIGHT, of Saint Martin's Lane, in the Liberty of Westminster, in the County
of Middlesex, Organ Builder, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Royal Letters Patent under the Great Seal of His United Kingdom of
Great Britain and Ireland, bearing date at Westminster, the Twenty-sixth day
of September, in the forty-ninth year of His reign, give and grant unto me,
the said Benjamin Flight, my executors, administrators, and assigns, His
especial licence, that I, the said Benjamin Flight, my executors, administrators,
and assigns, during the term of years therein mentioned, should and lawfully
might make, use, exercise, and vend, within that part of His Majesty's United
Kingdom of Great Britain and Ireland called England, His Dominion of
Wales, and Town of Berwick-upon-Tweed, my Invention of "A NEW METAL
NAVE, AXLE, AND BOX FOR WHEELED CARRIAGES, BY MEANS OF WHICH THE DANGER OF
OVERTURNING, AND THE CONCUSSION ARISING FROM CARRIAGES COMING IN CONTACT AT
THE NAVE, IS CONSIDERABLY LESSENED, THE NAVE IS MUCH STRONGER AND GIVES MORE
LIGHTNESS OF APPEARANCE TO THE CARRIAGES THAN THOSE NOW IN GENERAL USE, THE
BATTLING OF THE CARRIAGES IN ACTION IS ALSO LESSENED, THE OILING OF THE WHEELS,
WHICH NEED NOT BE TAKEN OFF FOR THAT PURPOSE, IS PERFORMED WITH GREATER EASE
AND FACILITY, AND THE OIL IS EFFECTUALLY PREVENTED FROM COMMUNICATING TO THE
SPOKES OF THE WHEELS;" in which said Letters Patent is contained a proviso,
obliging me, the said Benjamin Flight, to particularly describe and ascertain
the nature of my said Invention, and in what manner the same is to be per-
formed, by an Instrument in writing under my hand and seal, and cause the
same to be inrolled in His Majesty's High Court of Chancery, within two
calendar months next after the date of the said recited Letters Patent.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Benjamin Flight, do hereby declare that the nature of my said Invention, and
in what manner the same is to be performed are as follow (that is to say) :-
My Invention consists of a metal nave, axle, and box for wheeled carriages;
the nave is the block or centre of the wheel with the mortice holes therein to
receive the spokes; the axle is a fixture in the centre of the nave; the box
(which forms a part of the tree) receives the axle, which is confined therein by
a pair of chaps and a bolt going through the same; the reservoir to contain
the oil is within the external end of the axle, and the oil is introduced through
a hole in the cap of the nave, which is closed by a screw; the whole as
represented in the Drawings in the margin hereof. A wood nave, having a
metal lining in which to fix the axle, may be adopted, but I prefer the metal
nave. Fig. 1 in the margin hereof is an external view of the nave, axle, box,
and tree together; Fig. 2, an external view of the box and tree detached;
f, the hole to receive the bolt; Fig. 3, the axle detached; Fig. 4, the chaps;
Fig. 5, the section of Fig. 1. A, A, the nave; a, the axle fixed at the conic
part i, i, in the nave; B, the cap screwed within (or on the nave) tight against
the end of the axle at h, k, to keep it secure; C, C, C, the reservoir at the end
of the axle to hold the oil and the conductor of the oil to the surface of the
axle; b, a screw to the centre of the cap at which the oil is introduced; d, a
groove at the end of the axle for the chaps c, e, to secure it within the box;
f, a bolt through the box and chaps; g, the nut to the bolt.
In witness whereof, the said Benjamin Flight, have hereunto set my hand
and seal, the Twenty-first day of November, in the year of our Lord
