Automatic Vibrator Assembly Usable with a Concrete Finishing Tool

An automatic vibrator assembly usable with a concrete finishing tool and a float having industry standard float adaptor bolt layout, a front leading edge, and a trailing leading edge, the vibrator assembly comprising:

• a) a case comprising:
• i) a bottom section configured to cooperate with the float's industry standard float adapter bolt layout;
• ii) opposing front and back sides attached to the bottom section wherein the front and back sides are substantially parallel to the leading edge and a trailing edge of the cooperating float when case is attached to the float according to industry standard float adaptor bolt layout;
• iii) opposing first and second ends attached to the bottom section and positioned between the front and back sides such that the front side, first end, back side, and second end form a perimeter around the bottom section and together with the bottom section form a case chamber;
• and
• iv) a lid configured to attach to the perimeter of the case and to cooperate with the concrete finishing tool;
• b) a first vibrator mechanism attached to the bottom section of the case and positioned within the case chamber;
• c) a second vibrator mechanism attached to the bottom section of the case and positioned within the case chamber;
• d) a first switch assembly in electrical communication with the vibrator mechanism, wherein the first switch assembly is attached to the bottom section of the case near the back side of the case and positioned within the case chamber, comprises a first level sensor, and is configured to selectively engage the vibrator mechanism when a first threshold level of tilt is identified;
• e) a second switch assembly in electrical communication with the vibrator mechanism, wherein the second switch assembly is attached to the case near the front side of the case and positioned within the case chamber, comprises a second level sensor, and is configured to selective engage the vibrator mechanism when a second threshold level of tilt is identified;
• f) a variable speed controller positioned in the case chamber and in electrical communication with the vibrator mechanism;
• g) a variable speed input positioned on the case and in electrical communication with the variable speed controller;
• h) a dock for receiving a power source, wherein the dock attaches to the lid and wherein the power source is in electrical communication with the vibrator mechanism when it is positioned in the dock;
• and
• i) a master switch positioned on the case and in electrical communication with the vibrator mechanism, wherein the master switch selectively engages the vibrator mechanism for manual operation, the vibrator mechanism and first and second switch assemblies for automatic operation, or no vibrator mechanism.
