page_text: TO ALL PEOPLE TO WHOM THESE PRESENTS SHALL COME, I,
EDMUND BUNTING, late of Pitmans Buildings, Ironmonger Row, Old Street,;
London, and now of Saint John Square, in the County of Middlesex, Engine,
Maker, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under His Great Seal of Great Britain, bearing date at West-
minster, the Twenty-fifth day of March, in the thirty-seventh year of His
reign, did grant unto me, the said Edmund Bunting, my executors, adminis-
trators, and assigns, His said Majesty's especial licence, full power, sole
priviledge and authority, that I, the said Edmund Bunting, my executors,,
administrators, and assigns, and every of them, by myself and themselves, or,
by mine and their deputy or deputies, servants or agents, or such others as I,.
the said Edmund Bunting, my executors, administrators, or assigns, should at,
any time agree with, and no others, from time to time and at all times.
thereafter during the term of years therein expressed, should and lawfully
might make, use, exercise, and vend my "NEW INVENTED MACHINE, ENGINE,
OR INVENTION FOR PRODUCING A FORWARD AND RETROGRADE MOTION, CAPABLE OF,
BEING APPLIED TO MANGLES, PUMPS, CALENDARS, ROLLING PRESSES, OR ANY OTHER,,
PIECE OF MECHANISM," within that part of His Majesty's Kingdom of Great

page_text: Britain called England, His Dominion of Wales, and Town of Berwick-upon-
Tweed, in such manner as to me, the said Edmund Bunting, my executors,
administrators, and assigns, or any of them, should in their discretions seem
meet, and that I, the said Edmund Bunting, 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, accru-
ing, and arising, by reason of the said Invention, for and during the term of
years therein mentioned, to have, hold, exercise, and enjoy the said licence,
powers, privileges, and advantages therein-before granted or mentioned to be
granted unto me, the said Edmund Bunting, my executors, administrators, and
assigns, for and during and unto the full end and term of fourteen years from
the date thereof next and immediately ensuing, and fully to be complete and
ended, according to the Statute in such case made and provided; in which
said recited Letters Patent is contained a proviso, that if I, the said Edmund
Bunting, should not particularly describe and ascertain the nature of my
said Invention, and in what manner the same was to be performed, 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 one calendar
month next and immediately after the date thereof, that then the said recited
Letters Patent, and all liberties and advantages whatsoever thereby granted,
should utterly cease, determine, and become void, any thing therein-before
contained to the contrary in anywise notwithstanding, as in and by the
said recited Letters Patent, reference being thereunto had, will more fully
and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Edmund Bunting, do hereby declare that my said Invention is described in
manner following, that is to say:-
The parts whereby the forward and retrograde motion are produced consist
of an axis or spindle with two sockets; a bolt cut into the axis, which acts on
à fulcrum, which fulcrum passes through the spindle and also through the
middle of the bolt; the motion is given to this bolt, which locks and unlocks
alternately into the cavity in these sockets, by a rope or chain acting on a
stud which projects through each socket, and thereby presses down the bolt
and disengages each socket, as the rope or chain so presses as to cause the
socket so disengaged to turn freely round, so that the rope or chain is caused
to run off one socket that is disengaged while it runs on the other that is
engaged, and so on continually.
This Invention may be applied to work a mangle or callendar, raising

page_text: water, coals, or to any purpose where forward and retrograde motion is
required. It is worked by a common winch or handle, and it may be worked
with or without a fly, or with a pinion and wheel, to increase or decrease
the power, according to the weight required to be moved; the action
may be given by human strength, or by horse, steam, water, wind, or any
external power that can be applied.
Now the leading principle of this Invention is, that it produces a uniform
constant forward and retrograde motion, in in the most perfect, though in the
simplest manner, with less friction and less noise than any before invented.
Its strength and dimensions must always be in proportion to the machine it
is to work, and all the other parts of the machine may be in the common
dimensions of such machines in the usual way. This Invention is delineated
in the Drawing annexed to a scale of three inches to a foot, which dimensión
is about the size that will be required to work a mangle of common size.
Figure 1, in the plan hereunto annexed, is a section of the spindle on
being viewed from above. (A, A,) the bearings of the spindle that work
in brasses in the heads of the mangle; B, the mortice to receive the bolt;
C, the collar of the spindle against which the sockets work through which
the fulcrum of the bolt is fixed; D, the fulcrum that goes through the
collar of spindle on which the bolt acts.
Figure 2 is a side view of the spindle with the bolt fixed in it; the length
of the projecting part of the bolt must be such that, when one part is flush
with the spindle, the other to be of sufficient length to catch in the cavity of
the socket; A, the bolt; B, the fulcrum.
Figure 3 represents a spindle with sockets, bolt, studds, and ropes, handle
and fly; one rope leads from the top part of the socket, the other rope leads
from the bottom of the socket. A, A, are the studs which act in a mortice in
the socket, that, by the rope pressing in them, forces the bolt into the mortice
of the spindle at one end, and causes it to rise on the other, consequently
disengages it from one socket and causes it to be engaged with the other;
these studs may be slipped into the inside of sockets, and rivetted up inside
to prevent them falling out when in motion. It will be necessary to cut
away the back part of the mortice of the socket to cause the bolt
to engage the easier; B, the fly, and on the end of the spindle is a key
or nutt to keep the fly on; C, the handle or winch, on the outside of
which, on the spindle, is a key or nut to keep the handle from coming off, it
being necessary to pitch the mangle box to take the rollers out; a piece of
iron may be fixed, as at E, as shewn in number 1, 2, and 3, which should act

page_text: on a centre, and lap down on the spindle, to prevent the rope pressing on the
stud; or the same effect, will be produced by a common sliding bolt being
fixed to the collar of the spindle, which must project above the stud, that the
rope may not press on the stud to reverse the motion, but cause the box
to pitch.
In witness whereof, I, the said Edmund Bunting, have hereunto set my
hand and seal, the Twenty-second day of April, in the thirty-seventh 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, &c., and in the year of our Lord One thousand seven hundred
and ninety-seven.
SAM LEEDAM, Clerk to Mess's Miller & Sayer.
AND BE IT REMEMBERED, that on the same Twenty-second day of
April, in the year above mentioned, the aforesaid Edmund Bunting came
before our Lord the King in His Chancery, and acknowledged the Speci-
fication aforesaid, and all and every thing therein contained, in form above
written. And also the Specification aforesaid was stamped according to the
tenor of the Statute in that case made and provided.
Inrolled the Twenty-fourth day of April, in the year above written.
