摘要： A method of control and a control circuit for use in connecting all or sub-parts of a battery supply to a battery driven motor includes relays connected between a motor and each sub-part of a battery supply; a timer having a predetermined time period and which changes its output condition at the end of each time period; a motor speed selector for selecting either full motor speed or a portion thereof; and a switch arrangement which interconnects the relays, timer and motor speed selector. The switch arrangement provides for a first sub-part of the battery supply to be connected to the motor when the selector is in a less than full speed position and when the timer has one output condition. A second sub-part of the battery supply is connected to the motor when the selector is in a less than full speed position and the timer has a second output condition. The relays connect the full battery supply to the motor when the selector is in a full speed position.

摘要： This is an improvement for a powered floor scrubber which in use is moved forward and backward across a floor to be scrubbed. A scrub brush is rotated within a housing which is open at the bottom and water is supplied within the housing. The improvement consists of attaching double lipped suction squeegees at both the front and rear of the housing and connecting them both to a source of vacuum to suck up soiled water from the floor. The flexible squeegee lips are mounted in such a way that as the machine is moved forward the lips of the front squeegee fold together and shut off the airflow to it while the rear squeegee remains functional. When the machine is moved backward a reverse action of the squeegees occurs, so that there is always a functional squeegee sucking up soiled water behind the scrub brush while airflow to the opposite squeegee is shut off whether the machine is moving forward or backward.

摘要： A mechanism for controlling the speed and direction of a self-propelled machine, such as, for example, a floor cleaning machine, or the like. A rotatable control handle is provided and includes a speed control cam which moves a variable resistor slide member by means of a speed control arm connected to the cam follower. The variable resistor is connected between a battery power source and a propulsion motor to control the voltage to a speed control. The handle has a neutral position at which the machine is stationary, and rotation of the handle about its own axis in either direction will cause the motor to move the machine, the direction of rotation determining the direction of movement. The control handle carries a series of direction control cams which operate switches to control the direction of flow of current to the motor and thereby the direction in which the machine moves.

摘要翻译： 这是对动力地板洗涤器的改进，其在使用中向前和向后移动穿过地板进行擦洗。 洗刷刷在底部开放的壳体内旋转，并且水在壳体内供应。 改进之处在于将双唇吸气刮板安装在外壳的前部和后部，并将它们连接到真空源，以从地板吸入污水。 柔性刮板唇以这样的方式安装，使得当机器向前移动时，前刮板的唇部折叠在一起，并且在后刮板保持功能的同时切断气流。 当机器向后移动时，发生刮板的反作用，因此总是有功能的刮板将洗刷刷吸入污水中，同时关闭机器向前或向后移动到相对的刮板的气流。

摘要： A floor scrubbing machine for tile and other hard surface floors has a low enough profile height that it can be operated bodily under furniture or equipment such as, for example, seats in fast food stores. This floor scrubber has three principle functioning components, comprising a tank for cleaning solution and means to apply that solution to the floor, a powered scrub brush to agitate the solution on the floor, and a vacuum pickup squeegee system which dries the floor after scrubbing by removing spent solution from the floor to an on board tank. Floor scrubbers are known which comprise the three above elements, but are too tall to operate under the seats of fast food stores, except with a remote wand attachment which is cumbersome and slow. Other floor scrubbers are known which are low enough to operate bodily in such places but lack a vacuum pickup squeegee system for drying the floor, and leave a hard surface floor unacceptably wet, or require following operations to dry it. The present invention overcomes the shortcomings of these prior art floor scrubbers.
