Patent number: 9635990Abstract: A pivot suspension has two separate wheels and a channel, which has two ends axially extending across a floor cleaning or burnishing machine. One wheel is attached to a first end of the channel and the other wheel is attached to a second end of the channel. The pivot suspension further has a pivot rod that is pivotably attached to and is in line from front to rear with the machine. The pivot rod is fixedly connected to the channel at a location between the two channel ends. As a result, the wheels and channel are pivotably attached to the machine, by way of the pivot rod. In combination with at least one wheel or caster that is attached to a frame of the machine, the two channel wheels form three points of contact with a floor, even if there is dirt, debris, and unevenness on or in the floor.Type: GrantFiled: November 17, 2015Date of Patent: May 2, 2017Assignee: NSS Enterprises, Inc.Inventor: Jeffery R.

Patent number: 9554683Abstract: A floor cleaning or burnishing machine has at least one motor controller that is electrically connected to an analog joystick control, right and left potentiometers, an electrical power source, and right and left electrical drive motors. The right motor is mechanically connected to a right rear steering drive wheel and the left motor is mechanically connected to a left rear steering drive wheel. Rotational speed and direction of each rear wheel is independently controlled, by way of the joystick in cooperation with respective potentiometers, in either a forward or reverse direction. At any given time, each potentiometer controls a respective motor controller which individually controls the rotational speed and direction of a respective wheel, thereby each wheel is capable of rotating in an opposite direction at a different speed to the other wheel. To slow the floor cleaning or burnishing machine down, regenerative braking is utilized by operating the motors as generators.Type: GrantFiled: May 1, 2013Date of Patent: January 31, 2017Assignee: NSS Enterprises, Inc.Inventors: Jeffery R.
