    • An electrically operated grinding wheel is described wherein the grinding wheel is adapted with a slidable tool rest member which will automatically position itself at a preselected distance from the grinding wheel. As the grinding wheel becomes worn and its wheel diameter decreased, the slidable tool rest member will be automatically moved towards the grinding wheel and a safe operational spacing between the grinding wheel and the tool rest member maintained. This is achieved through a motorized gear train which is actuated by a photoelectric cell carried within the housing of the tool rest member. Another feature is that as the wheel is worn and approaches a preselected minimum diameter, a switch is automatically actuated which will turn off the power to the grinding wheel preventing its operation until such time that the worn grinding wheel is replaced.
    • 描述了一种电动磨轮,其中砂轮适于具有可滑动的工具架,其可以自动地将其自身定位在离磨轮预定的距离处。 当砂轮磨损并且其轮直径减小时,可滑动的刀架构件将自动地朝向砂轮移动,并且保持砂轮和刀架部件之间的安全的操作间隔。 这是通过机动齿轮系实现的,该齿轮系由在工具架的壳体内承载的光电单元致动。 另一个特征是,当车轮磨损并接近预选的最小直径时,开关被自动启动,这将切断砂轮的动力,防止其运转,直到磨损的磨轮被更换为止。

    • A control device that can be mounted against the face plate of a rocker switch automatically operates the rocker switch in accordance with at least one predetermined program. The device also allows the predetermined program to be overridden to manipulate the switch as desired without removing the device. The device includes a controller for activating the device according to parameters of the predetermined program; a power component that is responsive to the controller; and a rotating member that is rotated by the power component with respect to the switch. The rotating member includes an inclined plane extending from a surface thereof and adapted to abut the rocker. When the inclined plane abuts a first portion of the rocker, the switch is placed in an opened position, and when the inclined plane abuts a second portion of the rocker, the switch is placed in a closed position.
