Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
178 words
A device to facilitate coupling to plow assembly to the front end of a vehicle whereby the vehicle and the plow assembly have mating coupling means comprising: a lift mechanism having an actuator means attached to a first arm; a second arm of three telescoping sections adapted to connect to the lift mechanism and extend forward of the vehicle; hook means at the inner end of the second arm adapted to engage the lift mechanism; notched projection means at the outer end of the said second arm; U-shaped securing means secured around the said second arm and positioned adjacent the attachment of the actuator means and the first arm adapted to engage the lift mechanism to prevent lateral pivoting of the arm; chain means adapted to connect to the said notched outer projection means and having two depending sections; and clamping means secured to the end of each depending chain section adapted to connect to corresponding locations on the plow assembly whereby the latter may be raised in a balanced manner to facilitate the coupling to the vehicle.
Claim 2
Independent Claim
178 words
A device to facilitate coupling to plow assembly to the front end of a vehicle whereby the vehicle and the plow assembly have mating coupling means comprising: a lift mechanism having an actuator means attached to a first arm; a second arm of three telescoping sections adapted to connect to the lift mechanism and extend forward of the vehicle; hook means at the inner end of the second arm adapted to engage the lift mechanism; notched projection means at the outer end of the said second arm; U-shaped securing means secured around the said second arm and positioned adjacent the attachment of the actuator means and the first arm adapted to engage the lift mechanism to prevent lateral pivoting of the arm; chain means adapted to connect to the said notched outer projection means and having two depending sections; and clamping means secured to the end of each depending chain section adapted to connect to corresponding locations on the plow assembly whereby the latter may be raised in a balanced manner to facilitate the coupling to the vehicle.
Claim 3
Dependent Claim
38 words
A device as set forth in claim 1 in which the telescoping sections of the said second arm means include calibration indicia to facilitate adjusting the proper length thereof to raise the plow assembly in a balanced manner.
Claim 4
Dependent Claim
122 words
In a system including a vehicle having a plow hitch including a lift mechanism, plow-connecting brackets and an adjustable forwardly extending arm having depending hook means, the method of connecting a plow assembly to the vehicle hitch comprising the steps of: locating a point on the plow assembly wherein the plow assembly will be horizontally balanced when raised; securing the hook means to the balance point on the plow assembly; adjusting the length of the forwardly extending arm to a length so that the connecting brackets on the vehicle are adjacent to corresponding connecting brackets on the plow assembly; activating the lift mechanism to raise the plow assembly in a balance, horizontal position; and engaging the respective hitch and plow connecting brackets.
Claim 5
Dependent Claim
122 words
In a system including a vehicle having a plow hitch including a lift mechanism, plow-connecting brackets and an adjustable forwardly extending arm having depending hook means, the method of connecting a plow assembly to the vehicle hitch comprising the steps of: locating a point on the plow assembly wherein the plow assembly will be horizontally balanced when raised; securing the hook means to the balance point on the plow assembly; adjusting the length of the forwardly extending arm to a length so that the connecting brackets on the vehicle are adjacent to corresponding connecting brackets on the plow assembly; activating the lift mechanism to raise the plow assembly in a balance, horizontal position; and engaging the respective hitch and plow connecting brackets.
