ROBERT EARLY HARDAWAY, OF AUSTIN, TEXAS.
WIND AND WATER MOTOR.
SPECIFICATION forming part of Letters Patent No. 640,901, dated January 9, 1900.
Application filed March 5, 1898. Serial No, 672,677. (No model.)
To all whom zt 7mzay concern:
Be it known that I, ROBERT EARLY hIARD-
AWAY, a citizen of the United States, residing
at Austin, in the county of Travis and State of
5 Texas, have invented a new and useful Wind
and Water Motor, of which the following is
The invention relates to improvements in
wind and water motors.
Io The object of the present invention is to
improve the construction of windmills, more
especially that shown and described in Let-
ters Patent No. 588,572, granted to me Au-
gust 24,1897, and to increase the efficiency and
15 durability of the same and lessen the cost of
Another object of the invention is to pro-
vide a construction which besides being
adapted to be operated by the wind will be
20 capable of use in tidal rivers, streams, and
The invention consists in the construction
and novel combination and arrangement of
parts, as hereinafter fully described, illus-
25 trated in the accompanying drawings, and
pointed out in the claims hereto appended.
In the dra ings, Figure 1 is a vertical sec-
tional view of a windmill constructed in ac-
cordance with this invention. Fig. 2 is a
30 horizontal sectional view on the line 2 2 of
Fig. 1. Fig. 3 is an enlarged detail sectional
view of the lower bearing of the wind-wheel
shaft. Fig. 4 is an enlarged detail view illus-
trating the construction of one of the inter-
35 mediate bearings of the wind-wheel shaft and
illustrating the construction for throwing the
wind-wheels in and out of gear. Fig. 5 is a
detail view showing the wind-wheel shaft pro-
vided with a crank.
4o Like numerals of reference designate cor-
responding parts in the several figures of the
1 designates a vertical wind-wheel shaft
having its lower end 2 stepped in a bearing-
45 casing 3, provided with a circular ball race or
channel 4, receiving a series of antifriction-
balls 5, which support a bearing-disk 6. The
bearing-casing 3 consists of a horizontal bot-
tom plate provided with a central socket to
50 receive the lower end 2 of the wind-wheel
shaft, a horizontal top plate, and vertical side
walls, and the said casing is provided with
an outwardly-extending horizontal flange 7,
which is perforated for the reception of suit-
able, fastening devices for securing the bear- 55
mg-casing 3 in position.
The lower end 2 of the wind-wheel shaft is
reduced to receive the bearing-disk 6, which
fits against the shoulder formed by such re-
duction and is adapted to support the lower 6o
end of the wind-wheel shaft above the bottom
of the central socket of the bearing-casing 3.
The annular ball-race 4 of the bearing-casing
3 may be constructed in any suitable manner
and consists of vertical walls and a convex 65
bottom, and the bearing-disk 6 is provided at
its lower face with a convex ring 8, secured
in a recess of the disk 6 and forming a bear-
ing-surface for the tops of the balls. The
casing 3 is provided at one side with an oil- 7o
hole located above the annular ball-race and
adapted to permit the same to be readily sup-
plied with oil.
The wind-wheel shaf t,which may taper from
top to bottom, passes through a bearing-sleeve 75
9, located at the top of the casing 3 and ex-
tending downward through a central opening
of the same and provided with a horizontal
flange 10, which is bolted or otherwise secured
to the top of the bearing-casing 3. The sleeve 8o
10, which forms a journal-box, is composed
of two sections detachably secured together,
and a lining 11, of brass or other suitable
metal, is arranged within the sleeve 9. By
constructing the bearing-sleeve in two sec- 85
tions it may be readily removed for renewal,
repair, or adjustment. The top of the bear-
ing-sleeve is provided with an oil-recess 12
and has a cover or lid 13 for the same. The
cover may be hinged or it may be pivoted and 90
arranged to rotate horizontally to open and
The upper end of the wind-wheel shaft is
journaled in a bearing 14 of a casing mounted
on a frame consisting of a platform 15 and a 95
supporting- framework 16, suitably trussed
and braced by rods 17.
The casing 18, which receives and surrounds
a wind-wheel 19, is mounted upon the plat-
form of the supporting-frame and consists of oo
vertical partitions 20 and 21, diverging out-
wardly and composed of sections connected
