A NEW METHOD OF PRESERVING THE EQUALIBRIUM AND PREVENTING ALL KIND OF CARRIAGES FROM OVERTURNING
Year: 1807

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WILLIAMS, of Cornhill, in the City of London, Stationer, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Nineteenth day of
December, in the forty-seventh year of His reign, give and grant unto me,
the said John Williams, my exors, admors, and assigns, His especial licence,
full power, sole priviledge and authority, that I, the said John Williams, my
exors, adññors, or assigns, during the term of fourteen years therein mentioned,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "A NEW
METHOD OF PRESERVING THE EQUALIBRIUM AND PREVENTING ALL KIND OF CARRIAGES
FROM OVERTURNING;" in which said Letters Patent there is contained a proviso,
obliging me, the said John Williams, by an instrument in writing under my
hand and seal, to 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 Majesty's High Court of Chancery within one calendar month after
the date of the said recited Letters Patent, as in and by the same, relation.
being thereunto had, may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Williams, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are particularly
described and ascertained as follows, that is to say:-
Instead of putting each pair of the wheels of the carriage upon one and
the same inflexible axis or framing, having extreme parts answering the

page_text: purposes of an inflexible axis, as is usually donc,, whereby the said wheels in
each pair are made to preserve an unalterable position with regard to cach
other, I do substitute in the place of each of the said inflexible axis, or parts
answering the purpose of the same, a pair of levers proceeding or projecting
horizontally on each side in opposite directions from the same part of the perch
or middle bar or framing made use of to connect the wheels of and belonging
to the said carriage, and at right angles to the line of traction, and I do join
or connect each of the said levers to or with the said perch or middle bar
or framing made use of to connect the said wheels by means of an hinge, or
any other strong and well-made joint of the nature of an hinge, so fixed and
applied that each of the said levers shall be allowed to move in a vertical
circle, or up and down, but not at all sideways; and upon the extremities
of the said levers, which are formed into pivots or points of the axle of
the usual materials, I do put and secure my wheels. And, further, I do
support the body of the carriage upon springs of any fit and suitable
figure, by causing the said springs to bear or act upon the said levers, to.
which I do in some constructions affix the same, and in other construc-
tions I do cause the said springs to act or play, with one end not fastened
or fixed, and in this last case I do connect the said body with the framing
beneath by means of an upright bolt or pin which leaves room for play or
motion of the body up and down to a greater or less degree as may be
required, and of which play or motion the quantity may at pleasure be regu-
lated by an adjustment of the length of the said bolt or pin; I do also apply
other springs to support the fore and hind parts of the said body by causing
the said springs to bear upon the perch or middle bar or framing of the said
carriage, but in four-wheel carriages the said back and front springs are not
required, but may be used if preferable. And I do further declare that the
effect of the said levers and the interposed springs, as herein-before described,
is, that whenever an obstacle or cavity shall present itself or be met with in
the road to or by any one of the said wheels, the said wheel will rise over or
be depressed into the same without producing the same disturbance in the.
equilibrium or endangering the oversetting of the carriage in the same degree
as would happen in like circumstances to carriages constructed without the
use and application of my said Invention.
In witness whereof, I, the said John Williams, have hereunto set my
Irand and seal, this Nineteenth day of January, in the year of our
Lord One thousand eight hundred and eight.
JOHN WILLIAMS. (L.S.)
