WHEREAS His present Majesty King George the Third, by His Royal
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Sixth day of October last, hath been most graciously pleased to
give and grant unto me, JOHN SHANKSTER, of Great Pulteney Street, in the
Parish of Saint James, Westminster, in the County of Middlesex, Oval
Turner, and my exors, adiñors, and assigns, for the term of fourteen years
from the date of the said Letters Patent, especial license, full power, sole
priviledge and authority, to make, use, exercise, and vend, within that part of
Great Britain called England, His said Majesty's Dominion of Wales, and
Town of Berwick-upon-Tweed, my "NEW METHOD OF HANGING OF COACHES,
CHARIOTS, PHAETONS, CALASHES, GIGGS, CHAISES, AND OTHER CARRIAGES, WHEREBY
THE LIVES AND LIMBS OF HIS SAID MAJESTY'S SUBJECTS TO BE CONVEYED THEREIN
AND THEREBY ARE RENDERED MORE SAFE AND SECURE THAN IN OR BY ANY OTHER
CARRIAGE HERETOFORE MADE, BUILT, AND HUNG FOR THE CARRIAGE OR CONVEYANCE
OF PERSONS TRAVELLING AND OTHERWISE CONVEYED THEREBY;" in which said
Letters Patent is contained a proviso that I, the said John Shankster,
should particularly 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 seal, and cause the same to be inrolled in His said
Majesty's High Court of Chancery within one month next and immediately
after the date of the said Letters Patent, otherwise the said Letters Patent,
and all liberties and advantages thereby granted, should utterly cease, deter-
mine, and be void, as in & by the said Royal Letters Patent, reference being
thereto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in pursuance of the said Royal Letters Patent,
and of the above-mentioned proviso therein contained, I, the said John
Shankster, do hereby disclose, discover, and describe my said Invention in
manner following (that is to say):-
axle coming from and fixed
before, and to the middle rail
without an iron bracket or
No. 1, A represents an iron spindle or
to the middle rail or middle pillar or top rail
or middle pillar or top rail behind, with or
brackets to assist to carry the weight of the body, which center enters B, a
jointed swivel, the bed of which is composed of a joint on each side, to be
clipped by and fastened to the shackle or loops of the springs before and
behind. Little b and c represent two small bolts in bolt holes for the purpose
of suffering the spindles to play no further than consistently easy in the aperture
or hole in the swivel C. The swivel may be made in the following manner,
either in brass or iron or any hard-mixed metal, by leaving two shoulders
which form a hollow between where the bolts in the spindle are described, the
swivel forming a cap or die collar, which is the hole or aperture, and may be
screwed or rivetted together, the bottom part of which may be screwed or
rivetted on to the bed before described. No. 1, D represents an iron box or
frame, with a bolt, marked little e, playing through the center thereof, which
bolt is to drop in or clip the perch or a roller or rollers fixed on the perch.
The box, when affixed to the bottom of the body, will prevent the same from
overturning when entered by passengers, or from being affected by any biass
through their sitting on either side, but which bolt, nevertheless, by means of
a lead or other metal ball or roller rolling on two flyers or regulators marked f
and 9, to be affixed on two spindles marked h and i on the box, and may have
rule joints at the part where the spindles go through, that when the body
comes to the ground the rule joints may give upwards, and suffer the bolt to
loose itself in its box, which will prevent its being broken. The flyers or regu-
lators may
have loops or links or small chains on their internal points, to which
the bolt is to hang in the center, and to proceed through a case in the inside
of the box made to fit it. The ball, being put on the internal points of the
flyers or regulators, from its weight will naturally throw them down, and
_cause the bolt to drop, and clip the perch or roller or rollers, until the carriage
by any shock or obstruction be near overturning, in which case the ball, from
its gravity, will find its center towards the extreme points of the flyers or
regulators, being on the lowest side, and will consequently draw the bolt up,
make it quit the perch, and suffer the body to find its center. j and k are
bolts or pins on which the extreme points of the flyers drop when the bolt is
not level. Note.-The above box, bolts, and appurts may be applied under
the seat or seats of coaches, chariots, phaetons, or any other carriage used for

page_text: pleasure, and may be likewise affixed to a box or frame marked E hung
between the front spring and another hung between the hind spring, and
secured by braces, the difference of which will be, that the bolt will strike into
the box or frame instead of clipping the perch or roller.
The Invention may be also performed in the following manner; viz³, by a
box or frame, as before spoken of, and marked E, inclosing a wheel marked F,
with two shifters or regulators marked G, H; G hanging pendant by means of
the bolt or pin No. 1, thereon to the top of the wheel, and H hanging by
another pin No. 2, passing through the stem of or shaft of G, on the carriage
receiving any shock so as to endanger its overturning immediately draws up
the bolt marked affixed to the end of H, and admits of the body finding its
center. These shifters hang perpendicular when the carriage is upright, but
which on any bias or obstruction of the carriage the bolt I is drawn up from
the notch at the bottom of the box or frame marked E, but which shifters
again fall perpendicular, and again shuts into the notch, immediately on the
convulsion being over.
No. 2. This box or frame is to be hung between the front springs, and
another box or frame of the same construction with its contents to be hung
between the hind springs, and to be suspended by braces or chains. The
spindles or axles that are to go in at the center of these boxes or frames must
have square ends instead of round ones, as before described for the swivels
No. 1, and instead of bolts to confine it may have screwed nuts on the ends.
Note. The coachman's seat and footman's standing board may by this
Invention be suspended and kept free from danger by the spindles which
proceed from the body being made longer, and having square ends on which
may be slipped square eyes to fit, to which irons the seat and standing board
may be, agreeable to fancy, elevated or kept very low.
In witness whereof, I, the said John Shankster, have hereunto set my
hand and seal, this Sixth day of November, in the twenty-eighth year
of the reign of our Sovereign Lord George the Third, by the grace of
God of Great Britain, France, and Ireland King, Defender of the
Faith, and so forth, and in the year of our Lord One thousand seven
hundred and eighty-seven.

STER.
