Year: 1774

page_text: TO ALL PEOPLE TO WHOM THESE PRESENTS SHALL COME, I,
FRANCIS PINTO, of Well's Street, in the Parish of Saint Marylebone, in the
County of Middlesex, Gentleman, 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
Westminster, the Seventeenth day of November, in the fifteenth year of His
reign, did grant unto me, the said Francis Pinto, my executors, administrators,
and assigns, His said Majesty's especial licence, full power, sole privilege
and authority, that I, the said Francis Pinto, my executors, administrators, and
assigns, and every of them, by myself and themselves, or by mine and their
deputy or deputys, servants or agents, or such others as I, the said Francis
Pinto, 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, exer-
cise, and vend my "NEW-INVENTED PUMP OF A NEW CONSTRUCTION AND UPON
NEW PRINCIPLES, TO BE WORKED BY FIRE, BY MEANS WHEREOF WATER MAY BE
RAISED TO ANY HEIGHT AND IN ANY QUANTITY OCCASION MAY REQUIRE," within that
part of His Majesty's Kingdom of Great Britain called England, His.
Dominion of Wales, and Town of Berwick-upon-Tweed, in such manner as
to me, the said Francis Pinto, my executors, administrators, and assigns, or
any of them, should in their discretions seem meet; and that I, the said Francis
Pinto, 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, accruing, 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, priviledges, and advantages therein-before
granted or mentioned to be granted unto me, the said Francis Pinto, my execu-
tors, 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 compleat 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 Francis Pinto, should not particularly describe and ascertain the
nature of my said Invention, and in what manner the same was to be per-
formed, 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 four
calendar months 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, anything herein-
before contained to the contrary in anywise notwithstanding, as in and by the
said in part recited Letters Patent, relation being thereunto had, will more
fully and at large appear.
NOW I, the said Francis Pinto, do hereby declare the more essential parts
of my said Invention in manner following (that is to say):-
After a proper rarifying the air, or taking it out of a recipient, for which
purpose one may indifferently make use either of vapour, as it is commonly
practised; of flame or heat of living coals, according to the situation and pur-
poses the machine is designed for, one may (without it being necessary to make
use of any sort of pistoon) cause the water to ascend to a great height, and
that in several manners, which all depend on the following reasons. And it
must be observed that whenever I shall mention the recipient A, it ought to
be understood of that recipient which each pump must have in order to make
the vacuum in it by means of the flame, heat of living coals, or of the vapour,
as it is above said. The general notion is, that the atmosphere cannot cause
pure water (that is to say, without the mixture of other liquid) to ascend to a
greater height than that of thirty-two French feet, because in reality thirty-two
feet of water make the counter ballance against the impression of the atmo-
sphere. Now, I will shew upon the same that the weight of the atmosphere
shall cause twenty, twenty-six, and even thirty feet of water to rise to a very
great height through a tube that is either totally empty, or that contains a
much rarified air, since in this case the impression of the atmosphere is stronger
than the weight of thirty, twenty-six, or less feet of water.

Although the first and second Figure, together with the explanations that
are placed over against them, do not intirely shew the whole mechanism of the
pump, it does sufficiently what is necessary to understanil what I have said
just now.
Although my fire pump, after being disposed in the manner already said,
may be of the greatest utility on vast many cases,, however, many cases may
happen in which it would be more useful (instead of one single tube for the
water to ascend through) to make use of a repetition of tubes applied to a par-
ticular mechanism, as, for instance, it is seen in the third Figure, upon which
I shall make the most material explanations. R is the mouth, through which
the heat of burning coals (or the watery vapour instead of it) is to be intro-
duced into the recipient A;, but if they will make use of the flame instead of
these two mentioned means, in order to make the vacuum in the recipient A,
it will then be more convenient to introduce the flame through the side of the
recipient, as, for instance, in S. As soon as the recipient A shall become a
vacuum, the weight of the atmosphere shall begin to cause the water to ascend
at the same time through the pipes F, G, H, I, and these shall throw it into
their respective recipients B, C, D, E, which recipients communicate with tho
recipient A by means of the pipes marked Q: In the same manner as soon as
the mouths R or S of the recipient A shall open the valves, which every one of
the above said pipes F, G, H, I, ought to have, in order to keep them full of
water; shall shut, and as to the water which the recipients B, C, D, E, shall
have successively received, it shall naturally run into their respective, inferior
recipients L, M, N, O, by the means of a communication pipe which each of
the recipients B, C, D, E, shall have with its respective inferior recipients
L, M, N, O. Every one of these communication pipes must have its valve to
hinder the water which the recipients L, M, N, O, may have received from
re-ascending to their respective superior recipients B, C, D, E, from whence
they have received it, as it should happen as soon as the recipient A should be
a vacuum. In this manner the water which at every time shall ascend through
the pipe G, will be that which the recipient L shall have at a time received;
the water which at every time shall ascend through the pipe H, will be that
which the recipient M shall have at a time received; the water which at every
time shall ascend through the pipe I, will be that which the recipient N shall
have at a time received; and finally the water which at every time the re-
cipient O may have received, shall afterwards be ready to be employed to set
the machine aworking, &c.
This explanation is made upon four partitions of pipes to set an example,
but their number may be lessened or augmented according to the height to

of the single recipient A. I have supposed the recipient A to be at the upper
part of the pump; but if occasion requires it may be placed in a lower place,
and even near the bottom, or as it is seen in the second Figure.
In witness whereof, I, the said Francis Pinto, have hereunto set my
hand and seal, the Tenth day of March, in the fifteenth 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 seventy-five.
Inrolled the said Tenth day of March, in the year last above written.

When my new method she il be applied to the marine purposes, one
one must make use of th. Blaze only in order to make the vacuum
