AN IMPROVED CONSTRUCTION OF BLOWER
Year: 1853

page_text: LETTERS PATENT to Gage Stickney, of Hanover Street, Pimlico,
in the County of Middlesex, Mechanical Engineer, for the Inven-
tion of "AN IMPROVED CONSTRUCTION OF BLOWER."-A cominuni-
Sealed the 21st December 1853, and dated the 3rd September 1853.
PROVISIONAL SPECIFICATION left by the said Gage Stickney at
the Office of the Commissioners of Patents, with his Petition, on
the 3rd September 1853.
I, GAGE STICKNEY, do hereby declare the nature of the said Inven-
tion for "AN IMPROVED CONSTRUCTION OF BLOWER" to be as follows:-
The object of this Invention is to produce a fan or blower which
shall keep up a continuous and powerful blast of air by a small expen-
diture of power.
The improved blower consists of a rotary fan placed in a circular
case having open sides to admit of the in-draft of air. The compart-
ment in which the fan is placed is so formed as to allow of just sufficient
room for the rotation of the fan, which is provided with A shaped

channel. Into this channel the air is thrown through a small annular
opening by the fan, and it is led off by an air trunk, to be employed in
any required manner
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Gage Stickney in the Great Seal Patent Office on
the 3rd March 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
GAGE STICKNEY, of Hanover Street, Pimlico, in the County of Middlesex,
Mechanical Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of September, in the
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said Gage Stickney, Her special
licence that I, the said Gage Stickney, my executors, administrators,
and assigns, or such others as I, the said Gage Stickney, 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
CONSTRUCTION OF BLOWER," being a communication from abroad, upon
the condition (amongst others) that I, the said Gage Stickney, by an
instrument in writing under my hand and scal, 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.tlic 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 Gage Stickney, do hereby declare
the nature of the 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 Drawing here

page_text: to say)..
The object of this Invention is to produce a fan or blower' which
shall keep up a continuous and powerful blast of air by a small expen
diture of power.
1)
In carrying out this Invention a fan, having pointed blades somė.
what like the flukes of an anchor, is mounted in the centre of a circular
case, which is open at the sides to allow of an in-draft of air as the fan
rotates, and is provided at its periphery with an annular chamber, into
which the air is thrown, and from which the air is led off to be employed
as circumstances may dictate.

section taken through the middle of the case. Fig. 3, is a horizontal
section of the blower, taken in the line 1, 2, of Fig. 2, with the fan
removed. Fig. 4, shews the fan in front view, as detached from its
case. a, a, is a circular case having openings b, b, in its sides. From
the lip of the openings b, b, the flat sides gradually approach each other
(as at c, c, Fig. 3), and then expand into an annular chamber d, which
is provided with a vent at e, for the escape of the air from the blower:
This case a, is preferred to be made of cast iron, but other materials
may be employed, if thought desirable. To the sides of the case,
when made of cast iron or other strong material, bearing brackets f,f,
for carrying the fan spindle g, are bolted. On this spindle is keyed the
fan h, which consists simply of three curved arms cast on a boss, and
carrying severally a curved pointed blade.
The forward extremity of these blades extends to or projects a short
distance into the annular chamber d, (see Fig. 2,) and the form of
the blade in plan is such as will conform to the sectional figure of the
space through which it moves. Rotary motion is communicated to
the fan by a band from any first mover passing over a pulley i, keyed
to the spindle g; and the air, as it is drawn into the case a, by the
rotation of the fan, is conducted out of the case, and diffused as required
by a system of pipes k, k, connected with a main pipe k*, which is
bolted to the lip of the vent e.

page_text: Having now described the Invention of "An Improved Construction
of Blower," as communicated to me by my foreign correspondent, I
wish it to be understood that under the above in part recited Letters
Patent, I claim constructing the circular case of the blower with an
annular chamber at its periphery for receiving and transmitting the air
drawn in by the rotating fan, as above explained; and also combining
with such case a rotating fan set concentrically therewith, and provided
with blades, which approximate closely in form to the sectional area in
which they work.
In witness whereof, I, the said Gage Stickney, have hereunto set
my hand and seal, the Seventh day of February, in the year of
our Lord One thousand eight hundred and fifty-four.
GAGE STICKNEY. (L.S.)
