Patent number: 11035085Abstract: A method of mounting at least one spray gun assembly onto an arm of a line striper includes installing a first clamp onto the arm with the first clamp being connected to a first spray gun assembly and the first clamp having an opening. The first clamp is installed onto the arm by placing the arm within the opening of the first clamp without sliding the first clamp onto an end of the arm. The method also includes securing the arm of the line striper within the opening of the first clamp.Type: GrantFiled: January 28, 2020Date of Patent: June 15, 2021Assignee: Graco Minnesota Inc.Inventor: Steven R.

Patent number: 10857561Abstract: A material sprayer includes a hopper and a shaker assembly mounted onto a sidewall of the hopper. The hopper includes at least one sidewall that extends along a first plane. The shaker assembly includes a resilient bracket, an electromagnetic coil, and an armature. The resilient bracket is mounted to the sidewall of the hopper and includes first and second ends and a curved portion. The electromagnetic coil is mounted to a portion of the resilient bracket and is configured to generate a magnetic field in response to a current from a power source. The armature is mounted to a portion of the resilient bracket such that the armature is able to move relative to the electromagnetic coil along an acceleration axis that is orthogonal to the first plane of the sidewall of the hopper.Type: GrantFiled: January 15, 2018Date of Patent: December 8, 2020Assignee: Graco Minnesota Inc.Inventors: Jeromy D. Horning, Thomas E. Pauly, Steven R. Kuczenski

Patent number: 10584452Abstract: A line stripe includes a frame, a mounting arm extending from the frame, a G-shaped clamp, a vertical bar, an extension bar, and a spray gun. The G-shaped clamp has an opening through which the mounting arm is able to extend and a fastener configured to secure the mounting arm within the opening. The opening allows the first clamp to be mounted and then secured on the mounting arm without relative sliding between the first clamp and the mounting arm. The vertical bar is attached to and extends from the clamp. The extension bar is attached to and extends from the vertical bar, and the spray gun is attachable to the extension bar. The clamp is configured to be installable upon and removable from the mounting bar without having to remove similar G-shaped clamps from the mounting bar.Type: GrantFiled: January 20, 2017Date of Patent: March 10, 2020Assignee: Graco Minnesota Inc.Inventor: Steven R. Kuczenski

Patent number: 10563364Abstract: A line striping system comprises a chassis, wheels, a spray system, a propulsion system and a steering system. The wheels are mounted under the chassis. The spray system is mounted on the chassis. The propulsion system is mounted on the chassis to drive a wheel. The steering system is coupled to the chassis. The steering system comprises a handlebar rotatatable to steer a wheel, and a speed bar pivotable to control the propulsion system.Type: GrantFiled: September 26, 2018Date of Patent: February 18, 2020Assignee: Graco Minnesota Inc.Inventors: Christopher A. Lins, Thomas L. Triplett, James C. Schroeder, Steven R. Kuczenski, Barry W. Mattson, Brian M. Mulgrew, Douglas S. Ryder

Patent number: 10358781Abstract: A line striper comprises a sprayer secured to a frame, and a guided wheel assembly rotatably mounted to the frame. The guided wheel assembly includes an adjustment disk with screw notches along its outer diameter, an alignment plate coaxially surrounding and abutting the adjustment disk, alignment screws threaded through the alignment plate to engage screw notches on the adjustment disk, and an antirotation lock. The screws set a rotational alignment of the alignment plate relative to the adjustment disk, and the adjustment disk is coupled via a spindle axle to a guide wheel. The antirotation lock engages a locking feature on the alignment plate, thereby fixing the orientation of the guide wheel relative to the wheeled frame at an angle determined by the rotational alignment.Type: GrantFiled: January 20, 2017Date of Patent: July 23, 2019Assignee: Graco Minnesota Inc.Inventor: Steven R. Kuczenski
