COMPLETE SPECIFICATION filed by the said Alexander Melville Clark at
the Office of the Commissioners of Patents on the 22nd January 1881.
ALEXANDER MELVILLE CLARK, of 53, Chancery Lane, in the County of
Middlesex, Patent Agent. AN IMPROVED WIND ENGINE OR MOTOR." A com-
munication from abroad by Manuel Eugenio de la Torre, of Mexico City, in the
Republic of Mexico.
This Invention relates to that class of motors that are driven by the action of
the wind, and consists of a wheel provided with curved vanes rotating on a vertical
axis within a cylindrical frame, which frame is closed on two opposite sides and
opened on two opposite sides, so that the wind entering the wheel at one side shall
escape at the other side, and said frame is revolved or adjusted to the wind by
vanes fixed on its top, one of which vanes is adjustable and may be moved to
regulate the supply of wind to the wheel.
In the accompanying Drawings, Figure 1 is a plan of the device; Figure 2 is a
transverse section of the same on line x-x, Figure 3; Figure 3 is a vertical
sectional elevation on line y-y, Figure 2.
Similar letters of reference indicate
corresponding parts.
The supporting frame of the device consists of base A¹, upright posts B, and
C is the
horizontal cross pieces B', which unite above the centre of the base A'.
vertical shaft pivoted in the step a, and journalled at its upper end in the cross
pieces B¹. The turbine wheel of the device is composed of two similar discs D¹, D',
which are secured to the shaft C at a suitable distance apart to receive between
them the four curved vanes E, E. The inner edge of each of these vanes E, E, is
fixed in a point about half way between the centre and the circumference of said
discs D¹, D¹, and its outer edge reaches to the circumference of said discs D', D';
F is a vertical cylindrical frame, closed on opposite sides by curved quadrantal

page_text: plates H, H, and supported on a vertical pivot g that is fixed centrally in a step d
on top of the cross pieces or timbers B¹ of the frame, and also by means of its
annular track 62, which forms part. of its top and rests on the anti-friction
rolls m, m. Resting on the top of this frame F and secured by pivot g are the two
horizontal vanes G, G', the former of which is fixed and stationary on the top of
said frame F, while the latter is laterally movable through a quarter of a circle,
and has pivoted into its lower edge a wheel or roller o to enable it to move with a
minimum of friction, and being set over one of the plates H and opposite the other
plate H, these vanes G, G', under the influence of the wind control the movement
or adjustment of the frame F, turning said frame so that the wind shall be admitted
at one side of the wheel D' and escape at the opposite side in a greater or lesser
degree, according to the pressure or force of the wind. The frame F is held perpen-
dicularly and made to revolve easily by means of the anti-friction rolls m, m, fixed
on the top of the cross pieces B¹ of the frame, and projecting up against the circular
track 62, and of the antifriction rolls n, n, that project laterally from the lower part
of the uprights B against the lower ring o¹ of the frame F.
This device can be used with equal advantage on land to drive machinery of all
kinds, and on the water to move the wheels or propellers of vessels, it being easily
adapted to either purpose.
Having described the nature of the said Invention and the manner of performing
the same, I declare that what I claim as new and desire to secure by Letters Patent
is,—
1st. A wind motor constructed substantially as herein shown and described,
consisting of the shaft C, vertical curved vanes E, E, revolving cylindrical frame F
provided with quadrantal plates H, H, and vanes G, G³, as set forth.
2nd. In a wind motor, the combination with the revolving cylindrical frame F
provided with quadrantal plates H, H, of the fixed vane G and movable vane G',
substantially as herein shown and described.
3rd. In a wind motor, the combination of the posts B and cross pieces B¹
provided with antifriction rolls m, n, of the frame F, provided with annular track b³
and ring o, substantially as herein shown and described, whereby the said frame. is
easily revolved as set forth.
4th. In a wind motor, the combination with the supporting frame of the turbine
wheel D¹ and revolving frame F, substantially as herein shown and described.
In witness whereof, I, the said Alexander Melville Clark, have hereunto set
my hand and seal, this Twentieth day of January, A.D. 1881.
