ABSTRACT:
I FIELD OF INVENTION
This invention relates to a Water Cannon for directing a stream of liquid at a selected direction and inclination for a selected duration, and to a unique trunnion for varying the direction and inclination of a water or other type cannon.
II BACKGROUND OF THE INVENTION
U.S. Pat. Nos. 5,160,086 and 5,641,120 disclose methods and apparatus for forming a lighted laminar flow fluid stream.
However, neither of these references disclose means for varying the direction, inclination or duration of the fluid stream.
U.S. Pat. Nos. 1,526,341; 2,759,731; 3,342,492; 3,362,713disclose water pistols and cannons used as amusement devices. But these references do not involve trunnion support.
U.S. Pat. No. 4,905,900 discloses a method and apparatus for cleaning an air conditioner with a water cannon having an air gun therein for explosively discharging a quantity of water to dislodge sludge in the air conditioner. But it is not supported on a trunnion.
U.S. Pat. No. 4,058,256 discloses a water cannon mounted on a vehicle such as an armored car with a trunnion for controlling crowds of unruly people. But this device is not at all for amusement, and does not disclose the trunnion stops to prevent undue horizontal and vertical azimuth bearing of the cannon.
U.S. Pat. No. 4,338,852 discloses a trunnion having stops to control vertical azimuth bearing of a gun and a torsion bumper stop for absorbing shock loads as the gun nears the limits of its upward and downward motion. But this not a water cannon or an amusement device.
III SUMMARY OF THE INVENTION
A. Objects of the Invention
One object of the present invention is to provide a trunnion for varying the direction and inclination of an apparatus for launching a fluid or solid.
Another object of the present invention is to provide a method and apparatus for launching a fluid stream at a selected direction and inclination.
Another object of the present invention is to provide a method and apparatus for varying the duration of the fluid stream.
Another object is to provide a water cannon amusement device.
Another object is to provide means for varying the extent of horizontal variation permitted.
Another object is to provide resilient stop means for varying the horizontal inclination of the device.
Another object is to provide means for varying the extent of vertical variation permitted.
Another object is to provide resilient stop means for varying the vertical inclination of the device.
Other objects will be apparent from the following Description and Drawings.
B. Summary
In accordance with the present invention a trunnion assembly is provided for mounting a launching device including a horizontal locating assembly
10
to provide for selected horizontal movement of the the launching device and a vertical locating assembly
80
for varying the inclination of the launching device.
In one embodiment the launching device includes an accumulator tank
24
located below the locating assemblies
10
,
80
, which receives a liquid such as water. A valve assembly
30
including solenoid valve
32
is in fluid communication with the accumulator tank
24
. Valve assembly
30
may be electrically or pnuematically controlled by a controller
34
.
A stantion assembly
40
includes a curved stand
42
having a vertical portion
43
, a curved portion
45
and a horizontal portion
46
. Vertical portion
43
includes a lower end portion
44
which extends into a bearing assembly
50
including a cylindrical enclosure
51
which receives cylindrical bearing
52
made of known composite bearing material, and is connected to lower end portion
44
with removable fastening means
53
such as bolt
54
. Bearing
52
is movable with respect to enclosure
51
and mounting plate
55
to which is integrally connected as by welding.
A flexible conduit means
60
includes a first fluid containing conduit
61
. A second flexible electrical conduit
62
carrying wires
63
, and first conduit
61
are fed into lower end portion
44
and through stantion assembly
40
and extend through stand horizontal portion
46
and into a barrel assembly
70
including a cylindrical barrel
71
and through cylindrical barrel extension
72
.
Pattern openings
14
(FIGS.
2
-
2
D)are provided in base plate
55
to receive stop assemblies
20
including stop plates
21
having openings
22
to receive fasteners
23
. Stops
24
are mounted vertically on stop plates
21
. Resilient bumpers
25
made of elastomeric material having a Durometer value of about 60 to 100 A Scale are mounted on stops
24
with fasteners
26
which extend through respective openings
27
and
28
,
28
a
in stops
24
and part way through bumpers
25
. As shown in
FIGS. 2E and 2F
the fastener
29
may be formed integral with the bumpers, or the opening
28
a
may be threaded to receive threaded fastener
26
(FIG.
2
D). Thus the extent of horizontal rotation can be varied through varied placement of stop assemblies
20
into openings
14
.
The vertical locating assembly
80
fits within stand horizontal portion
46
and barrel extension
72
, and as shown in
FIGS. 3-6
includes a cylindrical casing
81
extending into horizontal stand portion
46
having elongated openings therein
81
a
to receive set screws
87
. The extent of the elongation of openings
81
a
allows limited adjustability of the extent of vertical travel of the barrel
71
. Located within casing
81
is a sleeve
82
having openings
82
a
to also receive set screws
87
, which fix the location of sleeve
82
. A pair of cylindrical dogs
83
and
85
each having cutaway portions
83
b
and
85
b
are located within casing
81
and are movable on shaft
86
a
extending from base
86
, having a head
86
b
located within barrel extension
72
and includes openings
86
c
to receive set screws
87
which render the shaft
86
a
movable with barrel
71
about the horizontal A—A in FIG.
1
.
Located within respective cutaway portion
83
b
and
85
b
are semi-cylindrical floating stops
84
and
84
S made of elastomeric resilient material such as polyurethane having a Durometer value of 60 to 100 A Scale. As shown in
FIG. 5
clearance
84
C exists between floating stop
84
and dog
85
. Similar clearance exists between floating stop
84
and dog
83
.
The Flexible conduit
62
containing wires
63
extends through barrel
71
to a barrel end
73
to a light assembly
90
to light the liquid carried through flexible conduit
61
and discharged from the second end
75
of the barrel, which houses an orifice assembly
100
. The light assembly
90
includes an electrical switch
91
, a light bulb
92
, and an activating button
93
held in place within barrel end
73
by end cap
74
. At the second end
75
an orifice assembly
100
includes an orifice
105
which may have a knife edge
106
. Optionally diffuser material
107
may be included to lower the Reynolds number of the liquid to create laminar flow.
