A NEW QUADRANT OR QUARTER CIRCLE AND STANDARD, WHICH, BY BEING AFFIXED TO DOORS, WOULD, BY THE HELP OF A LINE, PULLIES, AND WEIGHT, SHUT THE SAME WITH MORE EASE AND CERTAINTY, AND WITH LESS NOISE, THAN HAD BEEN DONE BY ANY METHOD HITHERTO MADE USE OF

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANCIS
MOORE, of Cheapside, in the City of London, Linen Draper, send greeting.
WHEREAS His present most Excellent Majesty King George the Third,
by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Thirteenth day of June, in the twenty-sixth year of
His reign, reciting that I, the said Francis Moore, had, by my Petition,
humbly represented unto His said Majesty that, after much study, I had
invented "A NEW QUADRANT OR QUARTER CIRCLE AND STANDARD, WHICH, BY
BEING AFFIXED TO DOORS, WOULD, BY THE HELP OF A LINE, PULLIES, AND WEIGHT,
SHUT THE SAME WITH MORE EASE AND CERTAINTY, AND WITH LESS NOISE, THAN HAD
BEEN DONE BY ANY METHOD HITHERTO MADE USE OF," and praying His Majesty's
Letters Patent for the sole use, benefit, and advantage of his said Invention,
within England, Wales, and the Town of Berwick-upon-Tweed, for the term
of fourteen years from the date of the said Letters Patent; in which said
Letters Patent is contained a proviso that if I, the said Francis Moore, shall
not 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 Majesty's
High Court of Chancery within one calendar month next and immediately
after the date of the said Letters Patent, that then the said Letters Patent,
and all liberties and advantages whatsoever thereby granted, should utterly
cease, determine, and become void, as in and by the said Letters Patent,
reference being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that I, the said Francis Moore, in compliance with
the said proviso, do hereby describe and ascertain the nature of my said
Invention, and in what manner the same is to be performed, by the Plan or
particular thereof hereunder written.
In witness whereof, I, the said Francis Moore, have hereunto set my
hand and seal, this Thirteenth day of July, in the twenty-sixth 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-six.

THO BURROUGHS.
Fig 1, Letter A, represents my new door quadrant, or quarter circle, with a
groove on the extream or outside, leading from B, where there is a hole,
to the point C. When this quadrant is screwed to the inside of a door, at or
near the top, by the strap D, through the holes E, E, and the line F is made
fast through the hole at B, and runs along the groove to C, and then over the
horizontal pully G, which must be fastened to the mantle, or under the top
part of the door case, or a piece of wood, which must lay flat over the door,
and then the said line F must run over the verticle pully affixed to the side of
the door case or jaumb; then to the end of this line F hang a weight K, which,
when heavy enough to overcome the weight of the door, the resistance of the
air and friction will pull the door to and shut it. This quadrant is for a door
which opens to the right-hand side.
Fig 2 represents the same quadrant with my new standard I, pullys 6, 6, 6,
and 7, 7, 7.
Fig 3, No. 1, represents the quadrant reversed, which is fixed to a door as
already described, will shut it; but this is for a door which opens to the left-
hand. Both these quadrants are to be placed or fixed to the inside of doors,
to pull or draw them to letter I, in Fig 2. No. 2, in Fig 3, and No. 2, in
Figure 4, represent my new. standard; the 2 latter in the shape or figure of a
dolphin, with the head made fast to the foot or plate 3, which standard
is to be screwed through to the foot 3, to the door post, checks, case, or side
which the door hangs to, so that the standard I, in Fig 2, or dolphin No. 2, in
Fig 3 & 4, may stand flat or nearly horizontal, being fastened by the foot 3

page_text: nearly to the door case or cheeks, and to stand as far from the base as to
admit of the quadrant No. 1 to pass or sweep within the pulley 6 fixed to the
back part of the dolphin's tail, by fastening the line F, F, F, to a hole at 6 in
the groove of the quadrant, and running the same line up the near side and over
the horizontal pulley 6, 6, 6, and then to and over the verticle pulley 7, 7, 7, in
the dolphin's head, and to the end of this line hang the weight K, K, sufficient
to overcome the weight of the door, resistance of the air, and friction; and such
weight will press or pull too the door and shut it. This is for a door which
opens to the right hand; the reverse must be for the left. In both cases,
where the standard is made use of, the whole apparatus must be placed behind
the door, by which means the weight K, K, suspended at the end of the
line F, F, F, is caused to press or force the door to; but when the quadrant
only is applied, the apparatus must all be withinside of the door; and in that
case the descent of the weight K pulls the door to and shuts it.
Fig 4 gives a different view of the shape of my dolphin, standard 2, foot 3,
pulleys 6 & 7, line F, and weight K.
AND BE IT REMEMBERED, that on the Thirteenth day of July, in the
year of our Lord 1786, the aforesaid Francis Moore came before our said
Lord the King in His Chancery, and acknowledged the Specification afore-
said, 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 Statutes made for that purpose.
Inrolled the Thirteenth day of July, in the year of our Lord One
thousand seven hundred and eighty-six.
