AN IMPROVED MODE OF AND MACHINERY POR OBTAINING AND APPLYING MOTIVE POWER, MORE ESPECIALLY DESIGNED FOR THE TRANS- MISSION OF THE SAME TO LONG DISTANCES."
Year: 1869

page_text: LETTERS PATENT to Horace Call, of Concord, in the County of
Merrimack, State of New Hampshire, United States of America, for
the Invention of "AN IMPROVED MODE OF AND MACHINERY POR OBTAINING
AND APPLYING MOTIVE POWER, MORE ESPECIALLY DESIGNED FOR THE TRANS-
MISSION OF THE SAME TO LONG DISTANCES."
PROVISIONAL SPECIFICATION left by the said Horace Call at the
Office of the Commissioners of Patents, with his Petition, on the
25th August 1869.
I, HORACE CALL, of Concord, in the County of Merrimack, State of
New Hampshire, United States of America, do hereby declare the nature
of the said Invention for "AN IMPROVED MODE OF AND MACHINERY FOR
OBTAINING AND APPLYING MOTIVE POWER, MORE ESPECIALLY DESIGNED FOR THE
TRANSMISSION OF THE SAME TO LONG DISTANCES," to be as follows:-
My said Invention relates more especially to the transmission of power
between distant localitics for various useful purposes.

page_text: To carry the said Invention into practice I construct a tank or cistern,
which is nearly filled with water. Submerged in this tank is a wheel
having buckets of a curved form. The said wheel turns on an an
axis which passes through the sides of the tank, the bearings being
packed to render them water-tight. An air pipe is introduced into the
tank and descends to the bottom of the same, its end being curved
and arranged immediately under the wheel in such a manner as to
discharge air into the buckets.
An apparatus for condensing air constructed in any suitable manner
is placed near the source of power, which may be a natural waterfall at
any distance from the place to which the power is to be transmitted.
From this condensing apparatus the air pipe herein-before described is
conducted to the tank, which is preferably arranged near the work to
which the power is to be applied. By this condensing apparatus air is
forced through the said pipe (which may be laid underground) for any
desired distance, and will discharge it under the buckets of the wheel,
displacing the water from the said buckets, and of course exerting a
lifting power on the circumference of the wheel equal or nearly equal to
the weight of water displaced. A drum may be attached to the axis on
the end projecting through the tank; or gearing in any of the forms
ordinarily used for connecting machinery to water wheels may be
employed. The power developed will of course be proportional to the
size of the wheel employed, and the condensing apparatus must be
sufficient to supply the air with such rapidity as to keep the buckets
full. The power required to force the air will not be great, but the
volume of air used in some cases will be considerable and will involve
the use of pipes large enough to supply it freely to the wheel.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Horace Call in the Great Seal Patent Office on
the 24th February 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HORACE
CALL, of Concord, in the County of Merrimac, State of New Hampshire,
United States of America, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of August, in the year

page_text: of our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Horace Call, Her special licence, that I,
the said Horace Call, my executors, administrators, and assigns, or such
others as I,. the said Horace Call, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed, should
and lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "AN IMPROVED MODE OF AND MACHINERY FOR
OBTAINING AND APPLYING MOTIVE POWER, MORE ESPECIALLY DESIGNED FOR THE
TRANSMISSION OF THE SAME TO LONG DISTANCES," upon the condition (amongst
others) that I, the said Horace Call, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Horace Call, do hereby declare
the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
Drawing forming a part of this Specification :-
My said Invention relates more especially to the transmission of power
between distant localities for various useful purposes.
To carry my said Invention into practice I construct a tank or cistern,
which is nearly filled with water. Submerged in this tank is a wheel
having buckets of a curved form. The said wheel turns on an axis
which passes through the sides of the tank, the bearings being packed to
render them water-tight. An air pipe is introduced into the tank and
descends to the bottom of the same, its end being curved and arranged
immediately under the wheel in such a manner that the air passed
through the said pipe will be discharged into the buckets.
An apparatus for condensing air constructed in any suitable manner is
placed near the source of power, which may be a natural waterfall at any
distance from the place whereto the power is to be transmitted. From
this condensing apparatus the air pipe herein-before described is con-

page_text: buckets e instead of the bucket wheel 6 illustrated in Figures 1 and 2.
The said drums are not placed vertically one over the other, but are
arranged with the series of buckets inclined, as shown, so that the over-
flowing air from the lowest bucket may fill the next, and so on in starting
the machine. The air pipe is arranged as described in connection with
Figures 1 and 2.
Having now fully described my Invention, and shown how the same
may be conveniently and advantageously carried into practice, I claim,
the mode of and machinery for obtaining and transmitting motive power,
substantially as herein set forth.
In witness whereof, I, the said Horace Call, have hereunto set my
hand and seal, this Fifth day of January, in the year of our Lord
One thousand eight hundred and seventy.
HORACE CALL. (L.S.)
