REMOTE CONTROLLED TOY VEHICLE WITH FLUID EJECTION UPON COMMAND
~ackqround of the Invention
This invention relates~to toys and more par-
ticularly to toys that are model machines, such as,
inter alia, sophisticated radio controlled electric
motor actuated water c~non dispensing tanks, trucks,
cars, airplanes and other types of vehicles.
Toyg from the earlicst days have been a
necessary conatituent of human health and tevelopment.
Competition has produced countless ingenious contriv-
ances which are model machines, such as steam-engines,
mobiles, tanks, etc. many remotely controlled by radio
transmitter receiver equipment for movement and eguip-
ment functions.
DescriPtion of the Prior Art
Hany toys are model machines of known equip-
ment and particularly object3 such as cars, trucks and
various military vehicles. Some of the military vehi-
cles have been known to dispen3e projectile~ but none
are known which mount a water cannon and selectively
dlspense a self containcd water supply.
SummarY of the Invention
This invention relates to water di~pensinq
model vehicles which may be radio controlled.
It is, therefore, one object of this inven-
tion to provide a new and improved model vehicle that
~slectively dispen~es a projectile of water.
another object of this invention is to pro-
vide a new and improvet remotely controlled motor

driven military type vehicle that selectively dispenses a
stream or burst of water.
A still further object of this invention is to
provide a new and improved self powered toy that dispenses a
liquid such as water.
A still further object of this invention is to
provide a model machine such as a self powered vehicle that
contains its own water supply and pressurizing means which
may be programmed to selectively dispense a stream or burst
of water.
Further objects and advantages of the invention
will become apparent as the following description proceeds
and the features of novelty which characterize this invention
will be pointed out with particularity in the claims annexed
to and forming part of this specification.

DescriPtion of the Preferred Embodiment
Referring more particularl~ to the drawings
by characters of reference, Figs. 1~.: disclose a track
mounted vehicle 10 comprisin~ a truck like body 11 the
wheels 12 of which drive a pair of tracks 13. Tracks
13 are provided with a plurality of spaced parallelly
arranged rid~es or treads 14, 1~' on the outside and
inner curface thereof that cxtends laterally there-
across for enga~ing with cooperating ~rooves 15 in the
periphery of wheels 12 or vice versa, as well known in
the art.
It should be noted that the term vehicl~ is
intended to mean all forms of model cars, trucks,
boats, aircraft and the like.
Vehicle 10 is driven by a pair of twin motors
16 which may be a Mabuchi product with one motor con-
nected to e~ch of tho wheels of the vehi¢le for inde-
pendent or joint rotation thereof in oither dir~ction
of rotation.

Motors 16 are interconnected to a battery
pack 17 through a radio controlled receiver 18. The
battery pack may be a rechargeable 9.6 volt NiCd Tyco
Industries, Inc.'s of ~oorestown, New Jersey product or
7.2 or other multi battery configuration of various
voltages from the same or different companies. An on-
off switch 19 forming a part of the radio controlled
receiver 18 may be used for controlling the energi-
zation of motors 16. An antenna 20 also forming a part
of the radio controlled r~ceiver 18 is utilized for
receiving signals from a suitabl¢ transmitter 21 dia-
grammatically shown in Fig. 8 but well known iA the
art.
The transmitter comprises a number of con-
trols the adjustment of which manipulates the various
parts of the vehicle during operation. Although trans-
mitters may vary between different manufacturers and
even between different models of the same manufacturer,
all have some similar controls for operating toy vehi-
cles .
As shown in Figs. 7 and 8, transmitter 21provides drive wheel control for vehicle 10 to direct
its movement pattern and also as hereinafter e~plained
the movement and control of a water cannon 22 mounted
thereon. An antenna 23 is suitably mounted on the
outside of the housing of transmitter 21 for broadcast-
ing control signals to the receiver 18 of the model
truck, in a well known manner.
The primary job of the operator is to control
and maneuver the vehicle, i. e., to direct its movement
pattern. The direction ~nd speed of the vehicle is
dcterrined by the surfac~ on which it travels.

In accordance with the invention claimed, the water
cannon mounted on truck 10 is intended to simulate a cannon
usually found on a tank 45 as shown in Fig. 5D. This cannon
may be movable, as shown, in Fig. 5D or fixedly mounted as
shown in Figs. 1 and 2. In either instance, the cannon is
used to disperse a stream or burst of water 24 from a
reservoir 25 forming a part of vehicle 10.
This stream or burst of water 24 is drawn through a
pipeline 26 by a hydraulic cylinder 27 the piston 28 and
piston rod 29 of which are operable by a motor 30 through a
crank 31 and gear box 32 in the usual manner.
When an operator transmits a given signal from
transmitter 21 by switch 33 identified as FIRE in Fig. 8,
D.C. motor 30 actuates piston rod 29 to the left as shown in
Fig. 2 which causes the hydraulic cylinder 27 to fill with
water and upon their movement to the right forces the water
from the hydraulic cylinder to flow under pressure through
pipeline 34 which is mounted in cannon 22 coaxially thereof
and through a nozzle 35 to a selected target.
Motor 30 may be controlled by a remote controlled
receiver 36 which is energized and controlled by transmitter
21.
Thus, transmitter 21 may control the functions of
driving the vehicle in a controlled pattern and selectively
firing the cannon to discharge a stream, slug or burst of
water. More than one transmitter may be used if so desired.
Different channels or frequencies of a transmitter can be
used to control the cannon's actions as well as functions of
the vehicle.

Fig. 4 discloses a modification of the structure
shown in Figs. 1-3 wherein a reservoir 37 may contain a hand
actuated pump 38 built therein which is pressurized by a
piston, not shown. A valve 39 interconnecting reservoir 37
with pipeline 34 is radio controlled by a signal 40 received
from transmitter 21 which energizes actuator 41 which
selectively opens and closes valve 39 in a known manner.
It should be noted that the water dispensing
control means shown in Fig. 4 may be mounted on any type of
vehicle and still fall within the scope of this invention
even though it is shown mounted on vehicle 10.
Figs. 5A-5D illustrates various vehicles on which a
water cannon may be mounted and remotely controlled by a
radio transmitter mechanism.
Fig. 5A illustrates a hydro type boat 42, Fig. 5B a
passenger car 43, Fig. 5C an airplane 44 and Fig. 5D a tank
45. Figs. 1-3 illustrate the means and hardware for mounting
on the vehicles shown in Figs. 5A-5D.
Fig. 6. illustrates a means for boat 42 to draw
water 46 through a pipeline or tube 47 into a hydraulic
cylinder 48 actuated by a crank 49 and gear box 50 by a motor
51. Motor 51 may be radio controlled in the manner
heretofore explained for the structure shown in Figs. 1-3.
The water drawn into hydraulic cylinder 48 and pressurized
and controlled by motor 51 is dispersed through pipeline 34
of cannon 22 which is mounted on any one of the vehicles
shown in Figs. 5A-5D.

Fig. 7 diagrammatically illustrates a module 52
containing a water dispensing cannon 53 that may be mounted
on tank 45 without changing the projectile dispensing cannon
54 forming a part of the tank's armor.
The module 52 comprises a housing or turret 55
pivotally movable about point 56 by a crank type or hydraulic
actuator 57 mounted on tank 45 for arcuately moving the tanks
turret over a predetermined path resulting in the water
cannon 53 being moved in a predetermined arc.
The water cannon is connected through a pipe line
or tube 58 to a suitable source of water under pressure such
as the hydraulic systems shown in Figs. 2, 3 and 4. As
diagrammatically shown in Fig. 7, cannon 53 may be elevated
or depressed in a vertical manner by an actuator 59 that is
radio controlled.
Fig. 8 illustrates the hand controls or switches
for operating the vehicle, turrets and water cannon mounted
on any of the vehicles disclosed. Although hydraulic
cylinders are shown and described, the actuators could
operate pneumatic cylinders and such is considered within the
scope of this invention.
The transmitter 21 shown in Figs. 8 discloses a
toggle switch 60 that controls the energization of the drive
motors of the vehicles such as the truck shown in Figs. 1-3
that causes forward and reverse operation of the vehicle
while toggle switch 61 results in the left or right movement
of the vehicle in a well known manner.
Toggle switch 62 causes right and left movement of
the turret housing 55 while toggle switch 63
WO95/21669 215 9 9 1~ PCT~S94/01436
results in up and down or vertical movement of the
water cannon.
Althou~h but a few embo~ ts of the inven-
tion have been illustrated and ~escribed, it will be
apparent to those skilled in the art that various
changes snd modifications may be made therein without
departing from the spirit of the invention or from the
scope of the appended claims.
