JORDAN HAMM, OF MAY, TEXAS.
WINDMILL.
SPECIFICATION forming part of Letters Patent No. 386,466, dated July 24, 1888.
Application filed November 1, 1887. Serial No. 253,991. (No model.)To all who071l it n c coacer:
Be it known that I, JoRDAN HIvrtar, a citi-
zen of the United States, residing at May, in
the county of Brown and State of Texas, have
5 invented a new and useful Improvement in
Windmills, of which the following is a speci-
fication.
My invention relates to an improvement in
windmills; and it consists in the peculiar con-
ro struction and combination of devices, that will
be more fully set forth hereinafter, and par-
ticularly pointed out in the claim.
In the drawings, Figure 1 is a side elevation
of a windmill embodying my improvements.
15 Fig. 2 is a longitndinal secion on line y y of
Fig. 3. Fig. 3 is a horizontal section taken
on the line x x of Fig. 1. Fig. 4 is a top plan
view.
A represents a vertical rectangular frame,
20 which is provided at a suitable distance froni
its lower end, in the center, with a bridge, B,
on the central portion of which, on its upper
side, is located an arched bracket, C. Across
the upper side of the frame A extends a pair
25 of transverse bars, D, which are connected at
their centers and in a vertical line with the
bridge by a block, E. In the center of this
block is journaled a short vertical shaft, F, to
the upper end of which is attached a vane,G.
30 H represents a vertical shaft, the lower end
of which is journaled in the bracket C, and is
stepped in a bearing, I, arranged on the up-
per side of the center of the bridge B, the np-
per end of the said shaft HI being journaled in
35 a vertical opening made in the lower end of
the shaft F, and thereby the said shafts F and
1H are independently revoluble.
K represents a vertical cylindrical case,hav-
ing the heads L, which are connected together
40 on one side for a suitable space by a curved
plate, M, which is preferably made of sheet
metal and extends around about one-third the
circumference of the case. If desired, a piece
of canvas of suitable size may be substituted
45 for the metallic plate 31. The upper side of
the case is pivotally connected to the lower
end of the shaft F, and the lower side of the
case is journaled centrally on the shaft H and
bears upon the upper side of the bracket C.
5o N represents the wind-wheel, which com-
prises the circular horizontal heads O, con-
nected together by means of concave wings P,
which are preferably made of sheet metal, andare curved, as shown in Fig. 3, and have their
sides bent around bolt-rods B, which connect
the circular heads of the wind-wheel. The
shaft H extends through the central portions
of the heads of the wind-wheel and is firmly
secured to the same, so that the wind-wheel
rotates with the said shaft.
S represents a lever, which is attached to
the lower portion of the shaft F just above the
casing, and extends outwardly from the said
shaft for a suitable distance. To this lever is
attached a depending rod, T, that extends to
within a suitable distance of the ground.
Near the lower end of the shaft H is at-
tached a band-pulley, U, by means of which
power may be transmitted from the said shaft
to any suitable machinery.
The operation of my invention is as follows:
When the lever S is released, the shaft F and
casing are disconnected and the casing cuts off
the wind from the wheel, as will be readily un-
derstood; but when the lever S, which is at-
tached to the lower end of the shaft F, is made
to engage with one of the notches T' in the
head L of the case, (by means of the depend-
ing rod T,) the shaft F and casing are attached
to each other and are free to rotate together,
so that the vane G turns the said shaft and
casing to expose one side of the wind-wheel to
the wind, and thus permit the wind to strike
fairly upon the wings of the wind-wheel one
side thereof, so as to rotate the wind-wheel
and the shaft H.
Having thus described my invention, I
claim-
The combination of the horizontal wind-
wheel, the semi-cylindrical case partly inclos-
ing the same and independently revoluble,the
case having tile notches T2 in its upper side,
the vane having the shaft or port whose lower
end forms the upper pivot for the said case,
and the lever S, having its inner end fast to
the vane shaft or port, and adapted to eligage
the said notches, and thereby cause the case
to expose any desired area of the wheel to the
wind, substantially as described.
In testimony that I claim the foregoing as my
own I have hereto affixed my signature in pres-
ence of two witnesses.
