page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
NEALE, of Leadenhall Street, in the City of London, Watchmaker, send
greeting.
WHEREAS His most Excellent Majesty King George the Second, by His
Letters Patent under the Great Seal of Great Britain, bearing date the
Twelfth day of July, in the eighteenth year of His reign, did give and grant
unto me, the said John Neale, His especial licence, that I, the said John
Neale, during the term of years therein expressed, should and lawfully might
make, use, exercise, and vend my new Invention of "A QUADRANTAL PLANET-
ARIAN MACHINE, BY WHICH THE ALTITUDE OF ANY OF THE PLANETS OR FIXED
STARRS MAY BE TAKEN, AS ALSO ALL THE USES OF THE ORBERY ANSWERED,"
within England, Wales, and Town of Berwick-upon-Tweed; in which said
recited Letters Patent there is contained a provisoe obliging me, the said
John Neale, by a writing under my hand and seal, to cause a particular
description of the nature of the said Invention, and in what manner the
same is to be performed, to be inrolled in His Majesty's High Court of
Chancery within four kalendar months after the date of the said recited Letters
Patent, as in and by the same (relation being thereunto had) may more at
large appear.
NOW KNOW YEE, that in compliance with the said provisoe, I, the said
John Neale, do hereby declare that the said Invention is to be performed
according to the Plan and the description thereof [intituled A Description of

The four outward. Lines in figue I includes the frame Ⓒ at the 4 corners and paralel with the center represents the pillers A and 1 shows the place for 2 studs in Brass to be fixt. In the upper one must run the pevit of a pinyon of 8 noted by A
in the mid-way between the 2 former which must take into a Cantrite wheel mackt tt of 32 Teeth and at the lower end a little beyond the Studs must be turned with a key as markt on the out side of the Frame, The Cantrite wheel this
turned must be trevited on a pinyon of 8 taking into the wheel B with 26 Teeth and on the other side into the great wheel C with 106. the wheel D. 4.& Revited on the Arbor E takes into the pinyon D. E. and also on the Lower end a Brass
Bobb screwed to it represented by D. E. f. which is all that is necessary for the inside part of the whole Machine - Except by any particular Request But how such a hifle should be able to conduct the motions of the Sun and all the
planets and Satalates on one side and a pair of hands for the uses of the Quadrant on the other will be best discovered by the motion workt on each side the frame - figure 2 on the Arbor I which comes thro' the plate and is
the whiel f Nº 60 taking into the pinion g. 6 on which # N: 60 is Revited leading common pinyon of 10 on I, a hand fixt on the point of E Arbor shews the degrees, and another on I point shows the minet, which
two hands are noted by N. M and 1 & K. the divided part of the Dial the Spring over the * shews that so soon as the observation be taken the Triger snaps immediately into the Teeth of II and effectually stops the hands
at the altitude required - In figure 5. P is the arbor which comes thro' on which is Revited that wheel In figure 0 which is turned by the key
the Body of the Sun by a Grew at Top. O is a wheel of 30
Teeth Rivited on a Socket fitted to this Arbor and at the Top of which is fitted a hand that leads Mercury being himself lead by a wheel of equal N from the Actor & over I is a Wheel of 52 markt I which leads S. 205 being
revited to a socket at the Top of it goes the hand that Leads Venus W. N°52 fixt over T Leads N° 12 whose Socket leads the Earth and Moon; over this Socket
a Bridge fixt by a Screw at a and s the cubor C in figure I
comeing thro' has the wheel Y. 40 which takes into Y.SC which is revited on a socket on the Top of which is the hand that leads Maus over y 40 is a Steel pinyon of & which leads Z. N: 164 revited to a Socket to which is fixt the hand

on the Top of which goes Saturn at the point with his king and five Satalets But as a wheel of 80 Teeth taking into a •punyon of 16 is in the same proportion of of 20 takeing into one of 4. as also a wheel of a 160
into one of 32 d: all keep the same exactness. Therefore in this machine the numbers may be all varied according to the sise of the Machine and the sise be according to the Will of the purchaser - As for the Moons in the Earth Supiter and Saturn they
all led by pinions of equal numbers fixt in the hollow part of the Arbors between the Satalet and the Body of that planet round which it moves and by a pingpon of the same N° also are each of the Indet directed upon which account they
may upon occasion be any or all of them had separate from the Oevery with their respective Globes - In figure 4 is represented the nature of the aforesaid Invention when for the cimusement of the civious they
made in a perimidicall method It represents the pedestall on which is a Steel Arbor x. .x is fixt perpendicular I is a brass nut which goes over the Steel Arbor x. x and takes into 2 wheels whose numbers must be as
12 to 29 8 1/2 these must lead 2 others of proportionable numbers back to the Arbor x. x. and lead a nut fixt to F. F. must lead 2 more whels S. S. whose numbers must be as 12 to 2. these must lead 2 others of proportionable
