JOHN W. ROMANS, OF DENISON, TEXAS, ASSIGNOR OF THIRTY ONE-HUNDREDTHS TO
SAMUEL E. RIVES AND THIRTY ONE-HUNDREDTHS TO WILLIAM T. CACKLEY, OF
DENISON, TEXAS.WINDMILL.
Specification of Letters Patent.Patented July 23,1912.
Application filed October 3, 1911. Serial No. 652,623.
To all whom it may concern:
Be it known that I, JoAN W. ROMA-s, a
citizen of the United States, residing at
Denison, in the county of Grayson and State
5 of Texas, have invented a new and useful
Windmill, of which the following aspeci-
fication.
, This invention relates to wind mills, one
of its objects being to provide a wind wheel
10 having means operated by centrifugal force,
for shifting the blades of the wheel, auito-
matically relative to the axis of rotation of
said wheel so as to maintain uniform the
speed of rotation of the wheel.
15 A further object is to provide improved
means for transmitting motion from the
power shaft of the windmill to the pump
rod, said means serving to multiply the
number of strokes of the rod obtained
20 A further object .is to provide a.vane hav-
ing improved means for maintaining it nor-
mally in a predetermined position relative
to the action of rotation of the wind wheel.
With the foregoing and other objects in
25 view which: will appear as thel description
proceeds, the invention resides in the com-
bination and arrangement of parts and in
the details of construction hereinafter de-
scribed. and claimed, it being understood
30 that changes in t.he precise embodiment of
the invention herein disclosed can be made
within the scope of what is claimed. with-
out departing from the spirit of the inven-
tion.
35 In the accompanying drawinogs the pre-
ferred form of the invention has been
shown.
In said drawings :--I{ igure 1 is a view
partly in side elevation and partly in section
40 of. a. wind mill ernbodyirnig the present'.un-
provements. Fig. 2 is a section on line
A-B Fig. 1. IFig. 3 is r rear elevation of
the wind wheel, its shaft being shown in
section. Fig. 4 'is r side election of tihe
45 head of the x ini d mill and of the cami wheel
supported therearob ovf. Fig. u is a peIspec-
tive view of the supper end portion of the
pump rod and of its yole and bearing mem
ber. Fig. 6 is a longitudinal section through
50 the tubular shaft of the caun wheel, the main
shaft being shown in elevation therein.
Fig. 7 is a side elevation of the vane con-
trolling lever and the segment actuated
+hereby.Referring to the figures by characters of 5m,
reference 1 designates the upper portion of
the tower of the wind mill and secured with-
in said upper portion is a tubular bearing 9
on which. is mounted a revoluble head .3.
This. head has a central opening 4 ad d' ao
tubular bearing extension ) projects down-
wardly from the head and is adapted to ro-
tate within the bearing member 2. Stand-
ards cand 7 are bolted or otherwise secured
upon and extend upwardly.from the head 3, 5
the lower end portions of these standards
bein preferably offset, as indicated in Fig..
4 so as to support, at one side of the open-
ing 4, a iubuilar shaft 8 to which is secured
Sa cm wheel 9 preferably formed with three 70
substantially ovate wings, as clearly inci-
cated in Fig. 4. These wings are adapted,
during .the rotation of the cain wheel, to
successively move under and elevate an anti-
friction roller 10 carried by a cross bar 11 75
the ends of' which are mounted within
sleeves 12 adapted to slide upon parallel
guide rods 13. These rods are secured at
their lower ends to the head 3 and at their
upper ends to' a cross bar 14 supported by 80
the upper ends of the standards 6 and 7.
A yoke 15 is connected to the rod 11 and
extends downwardly therefrom, the lower
or intermediate portion of the yoke being -
attached to the upper end of the pump rod 85
16. Said pump rod extends.longitudinally
through the tubulha' bearing extension 5 and
has a spring 17 mounted thereon, one end
of the spring bearing against a portion of
.the tower 1 while the other end bears upon 90
a collar 18 connected to the rod 16. Said
spring thus serves to hold the pump rod
normally pressed downwardly and it will be
apparent that each time one of. the wings
of the carm wheel 9 elevates the anti-friction 95
roller10 and the yoke 15, the rod 16 will
be moved upwardly therewith, but as. soon.
as the anti-friction roller 10 passes the ele-
vated end or apex of the wing, the spring
17 will throw the rod 16 and the parts con- .iO
nected thereto -downwardly into position to
e promptly elevated by the next wing 'of
the wheel 9 engaging 'the roller 10.
A gear 19 is secured to one end of the
tubular shaft 8 and meshes with a smaller l05
gear 20 secured toscounter shaft 21. This
counter shaft is journiled within- the stand-
ard 7 and within an additional standard 221,033,351.
