Abstract
Abstract A plug body has in it a cavity in which a water driven rotor is rotatively mounted. A water conduit in the plug body has an intake opening positioned forwardly of the rotor and a discharge opening positioned to direct water onto the rotor to rotate the same. The weight of the rotor is off-center relative to its axis of rotation and when said rotor is rotated the off center weight will cause said rotor to vibrate and impart to the plug body an erratic movement alluring to fish. Means controlled by the rotor to jet water sidewise from the plug body and further increase its erratic movement is also provided.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
160 words
In a plug type fishing lure, a plug body having in its rear end portion a cavity; a water driven rotor mounted for rotation in said cavity about an axis and with the weight of the rotor off-center relative to said axis; a water conduit in said plug body having an intake opening forwardly of said rotor and a discharge opening positioned to direct water onto said rotor to thereby rotate said rotor, the off-center weight of said rotor relative to its axis of rotation vibrating said rotor and imparting to the plug body an erratic movement alluring to fish when the plug body is in water and there is substantial relative movement between the water and the plug body; at least one water discharge port extending from said cavity outwardly through a side wall of the plug body; and means operable in opening and closing said port connected with said rotor and controlled by rotary movement of said rotor.
Claim 2
Dependent Claim
160 words
In a plug type fishing lure, a plug body having in its rear end portion a cavity; a water driven rotor mounted for rotation in said cavity about an axis and with the weight of the rotor off-center relative to said axis; a water conduit in said plug body having an intake opening forwardly of said rotor and a discharge opening positioned to direct water onto said rotor to thereby rotate said rotor, the off-center weight of said rotor relative to its axis of rotation vibrating said rotor and imparting to the plug body an erratic movement alluring to fish when the plug body is in water and there is substantial relative movement between the water and the plug body; at least one water discharge port extending from said cavity outwardly through a side wall of the plug body; and means operable in opening and closing said port connected with said rotor and controlled by rotary movement of said rotor.
Claim 3
Dependent Claim
28 words
The plug type fishing lure as claimed in claim 1 in which the water driven rotor has vanes extending in generally radial directions against which the water reacts.
Claim 4
Dependent Claim
39 words
The plug type fishing lure as claimed in claim 1 in which the off-center weight of said rotor is provided by a weight attached to said rotor in a position outwardly from the axis of rotation of said rotor.
Claim 5
Dependent Claim
62 words
The plug type fishing lure as claimed in claim 1 in which an opening is provided in the plug body rearwardly of said rotor between said cavity and the exterior of the plug body, whereby water outside of the plug body and moving in a rearward direction relative to and close to the plug body will exert a suction in said cavity.
Claim 6
Dependent Claim
76 words
The plug type fishing lure as claimed in claim 1 in which two approximately diametrically opposite water discharge ports extend from said cavity outwardly through side walls of the plug body and in which means operable in opening one of said ports and simultaneously closing the other port whereby jets Of water will be discharged alternately from opposite sides of said plug body, is connected with said rotor and controlled by rotary movement of said rotor.
Claim 7
Dependent Claim
74 words
The plug type fishing lure as claimed in claim 5 in which the means operable in opening one of said ports and simultaneously closing the other port is a movably supported valve carrying member connected with the rotor and two valves carried by said valve carrying member, each valve being movable by said valve carrying member into open and closed relation to one of said ports in response to rotary movement of said rotor.
Claim 8
Dependent Claim
59 words
The plug type fishing lure as claimed in claim 5 in which the means operable in opening one of said ports and simultaneously closing the other port is an approximately semicircular member of substantial width on the water driven rotor movable alternately past said ports in close proximity to said ports and in water shut-off relation to said ports.
