Abstract
Abstract A water fowl decoy contains a radio receiver adapted to receive signals from a remote radio transmitter. The receiver connects to an amplifier, one or more servos and other components within the decoy. A rudder operable by a servo steers the decoy. An electric motor drives a propeller to motivate the decoy. A folded or recessed grapple is extended when a servo mechanism within the decoy responds to a signal from the transmitter through the receiver. The decoy carries a battery pack and internal flotation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
116 words
A decoy controlled from a remote transmitter and comprising a hollow animal figure, a covered entry into the figure, external guide means, external propelling means, an electrical power source, a receiver responsive to the transmitter, a receiveramplifier, a first servo mechanism responsive to the receiver, a second servo mechanism responsive to the receiver, a motor, means on the amplifier connecting the power source and the motor to control the motor output, means connecting the motor to the propelling means, linkage between the first servo mechanism and the guide means, a grapple external of the figure having extending and retracted positions, and means responsive to the second servo mechanism adapted to retain the grapple in retracted position.
Claim 2
Dependent Claim
116 words
A decoy controlled from a remote transmitter and comprising a hollow animal figure, a covered entry into the figure, external guide means, external propelling means, an electrical power source, a receiver responsive to the transmitter, a receiveramplifier, a first servo mechanism responsive to the receiver, a second servo mechanism responsive to the receiver, a motor, means on the amplifier connecting the power source and the motor to control the motor output, means connecting the motor to the propelling means, linkage between the first servo mechanism and the guide means, a grapple external of the figure having extending and retracted positions, and means responsive to the second servo mechanism adapted to retain the grapple in retracted position.
Claim 3
Dependent Claim
25 words
A radio-controlled decoy in accordance with claim 1 further comprising an internal flotation member having a buoyancy factor exceeding the negative buoyancy of the decoy.
Claim 4
Dependent Claim
17 words
A decoy in accordance with claim 2 further comprising an external flotation member beneath the animal figure.
Claim 5
Dependent Claim
20 words
A decoy in accordance with claim 1 further comprising a towing attachment fixed at the rear of the animal figure.
Claim 6
Dependent Claim
56 words
A decoy in accordance with claim 1 wherein the external grapple comprises a resilient wire fixed to the animal figure, a grapple hook at the opposite end of the wire, and a locking pin extending from the animal figure with which the grapple hook is engageable, said lock pin being retractable by the second servo mechanism.
Claim 7
Dependent Claim
134 words
A decoy in accordance with claim 1 wherein the external grapple comprises a pair of grapple arms, a pair of substantially vertical pivots extending from the animal figure at spaced intervals, each grapple arm being fixed to the external end of a pivot, lever arms extending from the pivots internally of the animal figure, an actuating rod attached to each lever arm, a power arm on the second servo mechanism means linking each rod to the power arm such that each lever arm moves in an arc to turn its respective pivot to extend and retract the horizontal grapple arm externally attached to the pivot between retracted and extended positions in response to the servo mechanism, the extended positions of the grapple arms being divergent from the pivots and forward of the animal figure.
Claim 8
Dependent Claim
59 words
A decoy in accordance with claim 1 wherein the external grapple comprises a pair of grapple arms extending horizontally from the animal figure at spaced intervals, a power arm on the second servo mechanism Adapted to extend and retract the horizontal grapple arms, the extending positions of the grapple arms being respectively divergent and forward of the animal figure.
