Patent number: 5485690Abstract: A lightweight snowplow configured of a number of small components, each easily lifted, moved, assembled, dis-assembled and stored by an average individual. The snowplow is especially suitable for use with small vehicles such as small trucks, utility vehicles and cars. The snowplow features novel alternate arrangements for operational lifting, stopping and lowering of the snowplow and a quick-hitch/release mechanism for easy plow attachment purposes. Finally, the mounting structure to which the plow is attached and detached is designed so as to be able to fit most small utility vehicles with two fore and aft frame chassis members and a frame mounted metal bumper without need for welding or special custom fit-up.Type: GrantFiled: January 18, 1994Date of Patent: January 23, 1996Inventor: James P. MacQueen

Patent number: 5435082Abstract: An apparatus, for stabilizing a plowing implement mounted on a motor vehicle, comprising a rigid stabilizer member having first and second opposed ends. One end of the stabilizer member supports an attachment device for attaching the stabilizer member to a plowing frame secured to a motor vehicle. The attachment device allows pivoting motion of the stabilizer member relative to the plowing frame. The second end of the stabilizer member has an abutment surface for abutting against a pivotable portion of the plowing implement when the plowing implement is raised into travel position. The stabilizer member is pivotable into an inoperative position where complete freedom of movement of the plow is achieved and an operative position by a control mechanism. When the stabilizer member is in its operative position, the abutment surface abuts against a pivotable portion of the plowing implement to minimize undesired bouncing of the plowing implement while the vehicle is traveling on a roadway.Type: GrantFiled: August 10, 1993Date of Patent: July 25, 1995Inventors: Eugene R. Frenette, Henry E. Frenette, Dana E. Frenette

Patent number: 5346018Abstract: An inventive three-point hitch assembly that attaches to the front end of a truck or pickup and supports at three points a plurality of implements or tools. It has a belt-driven power take-off for rotary tools that is controlled by an electric clutch and driven by a pulley attached below the truck engine pulley. A hydraulic lift cylinder raises and lowers the hitch and implement or tool, which by the hitch parallelogram form maintains the implements in a vertical orientation. The lift cylinder hydraulic pressure is supplied by connections to the truck power steering system via electrically controlled solenoid valves.Type: GrantFiled: October 26, 1992Date of Patent: September 13, 1994Inventor: Rick L. Koster

Patent number: 5205058Abstract: A roadbed maintenance device includes a first frame adapted for attachment to the front end of a vehicle, and a second frame to which a moldboard is joined. The first frame and the second frame are pivotably joined by a parallelogram linkage, so that the second frame can be pivoted between a lowered position in which the lower edge of the moldboard touches the roadway, and a raised position in which the lower edge of the moldboard does not touch the roadway. The pivoting movement is preferably accomplished by biasing the second frame toward the raised position, and applying a force to accomplish pivoting toward the lowered position. The pivoting force is provided by a gas-actuated cylinder linked to the second frame, using a compressed gas source on the vehicle. The moldboard is desirably made of molded rubber.Type: GrantFiled: April 25, 1990Date of Patent: April 27, 1993Inventors: A. Gregory Allen, Frank T. Samarzea

Patent number: 5191729Abstract: Safety apparatus for use in a moldboard assembly having a plurality of horizontally aligned trip blade units pivotally supported in the bottom of the moldboard frame so that the units move independently between a downwardly extended operative position and a rearwardly extended, fully tripped position. A biasing mechanism urges each unit into the operative position with a predetermined amount of force. A control mechanism further regulates the biasing force exerted on each unit so that the biasing force first increases as the unit moves out of the operative position and then decreases as the unit continues to move into the fully tripped position. The force exerted on each unit when in the fully tripped position is considerably less than that used to hold the unit in the operative position thereby preventing the assembly from lifting as it moves over an obstacle.Type: GrantFiled: September 30, 1991Date of Patent: March 9, 1993Assignee: Frink America, Inc.Inventor: Jan H. Verseef

Patent number: RE35700Abstract: A detachable snowplow blade lift assembly including a .?.mount.!. .Iadd.mounting .Iaddend.frame permanently connected to the vehicle frame. A snowplow assembly including an A-frame and a snowplow blade mounted on the A-frame is pivotally connected to the .?.mount.!. .Iadd.mounting .Iaddend.frame. A lift frame assembly including a lift actuator mechanism for raising and lowering the A-frame and snowplow blade is pivotally connected to the A-frame for rotation about a pivot axis. The snowplow blade lift assembly also includes a mounting arrangement for releasably connecting the A-frame and lift frame as a unit to the vehicle for pivotable movement of the A-frame relative to the vehicle and to the lift frame about the pivot axis. The A-frame mount affording pivotal movement of the A-frame and the lift frame about a common pivot axis provides a snowplow blade lift assembly which can be attached to, and detached from, the mounting frame as a unit and which has the capacity to stack snow.Type: GrantFiled: December 1, 1995Date of Patent: December 30, 1997Assignee: Douglas Dynamics, L.L.C.Inventors: Gary E. Watson, James R. Doornek, Thomas P. Fechter
