CUT-OUT DEVICE FOR WINDMILLS.Specification of Letters Patent. Patented June 25, 1918.
Application filed November 27, 1917. Serial No. 204,226.To all whom it may concern:
Be it known that I, PHIL M. PENNING-
TON, a citizen of the United States of
America, residing at Bellevue, R. F. D. #2,
5 in the county of Clay and State of Texas,
have invented new and useful Improvements
in Cut-Out Devices for Windmills, of which
the following is a specification.
The invention relates particularly to an
10 improved attachment for wind mills, where-
by the mill may be thrown out of gear auto-
matically when the supply tank becomes
filled.
Another feature of the invention resides
15 in the provision of a latch for the lever
which throws the mill in gear, this latch
being conjoined with the weight that is
rendered operative to release the latch only
when the float carried within the tank is
20 lifted by the water which fills the latter.
Still another feature of the invention is
the provision of a device of this character
which is simple in construction, durable and
effective in operation and which can be
25 manufactured at small cost.
Other and further features will be made
apparent as the detail description of the de-
vice progresses.
To the exact construction in which the de-
30 vice is shown and described, the invention
is not to be restricted. The actual reduc-
tion to practice may show certain changes
or alterations to be desirable and these the
right is claimed to make in so far as they do
35 not depart from the spirit of the subjoined
claims.
In the accompanying drawings:
Figure 1 is an elevation of a portion of a
windmill tower, showing the improved cut-
40 out mechanism attached thereto.
Fig. 2 is a view looking in the direction
of the arrow in Fig. 1.
Fig. 3 is a section on the line 3-3 of
Fig. 1.
45 Referring to the drawings in which only
a portion of a windmill tower is shown, the
arms 1 are attached by any suitable means
to a post 2 of the tower, the lever 3 having
one end pivotally mounted between these
50 arms 1. The lever 3 has attached to it the
usual rod 4 which leads to the mill and is
designed to throw the latter into or out of
gear, depending on whether it is drawn
down or raised. The rod 4 is connected to
55 the lever 3 at a point slightly to one side
of the longitudinal center of the latter andnearer to its pivotal connection with the
arms 1 than to its free end. Thus as the
lever 3 is moved from, the horizontal posi-
tion downward into the vertical position, the 60
rod 4 operates to throw in the clutch on the
.windmill, this portion of the windmill not-
being shown because it is not essential to an
understanding of the invention. The con-
ventional form of windmill clutch is ar- 65
ranged to stand normally in the inoperative
position, so that this position tends to exert
a pull on the rod 4 to raise the lever 3 to a
horizontal position unless the latter is re-
tained in the vertical position before re- 70
ferred to.
With the present invention a latch 5 is
designed for attachment to the post 2 of the
tower. This latch comprises a resilient plate
having a right angled end 6 by means of 75
which it is attached to the end of the post,
the plate further having a depression 7
formed in the upper face, in which depres-
sion the end of the lever 3 engages to hold
the latter in the vertical position. On the 80
forward end of the latch but to one side,
there is attached a weight 8, the end of a
cable 9 being also attached at this point.
The cable rises upwardly and passes over
a pulley 10 rotatably mounted in a bracket 85
11 which is attached to the post 2 of the
tower. From the pulley 10, the cable 9
passes to a second pulley 12 which is mount-
ed in a bracket 13 that is attached on top
of the water tank 14, the cable' passing down 90
into the water tank and carrying at its end
therein a float 15.
When the water tank 14 is empty, the
float 15 remains suspended therein and is of
greater weight than the weight 8. There- 95
fore, this float exerts a pull on the cable
9 which keeps the latch 5 raised to its high-
est position. The windmill being in the in-
operative position because of the lever 3
being raised so that the rod 4 does not exert 100
a force to keep the clutch engaged, the lever
is depressed to the vertical position by hand
and its free end made to engage in the de-
pression 7 formed in the latch 5, in which
depression it remains engaged and keeps 105
the windmill clutch in engagement because
of the float 15 tending to raise the latch 5.
The windmill then begins the pumping op-
eration and delivers the water to the tank
14 (these connections not being shown be- 110
cause of being unessential to an understand-
ing of the invention) which water, when1,270,320.
