Abstract
An imprint roller comprises a roller assembly, a frame, and a motor assembly. The roller assembly is supported on the frame and includes a vibrator head and a roller tube having a roller surface. An operator of the imprint roller may grip the frame and support at least a portion of the frame during operation of the imprint roller. The motor assembly is supported on the frame and operable to transfer mechanical energy through the frame to the vibrator head included in the roller assembly.
Claims18
A vibratory device for working concrete comprising:
- a frame having a first end and a second end opposite the first end,
- an implement configured to be removeably coupled to the first end of the frame, the implement including a vibrator head and a concrete engaging tool, the vibratory head transferring vibration to the tool,
- a motor assembly configured to be removeably coupled to the second end of the frame and operable to transfer mechanical energy through the frame to the vibrator head, and
- a frame extension having a first end and a second end opposite the first end, wherein the first end of the frame extension is configured to be removeably coupled to one of the implement and the second end of the frame, and the second end of the frame extension is configured to be removeably coupled to one of the motor assembly and the first end of the frame to change the distance between the motor assembly and the implement while transferring the mechanical energy through the frame extension;
- and
- wherein the frame extension comprises an extension drive member positioned within an extension drive member housing, wherein the extension drive member is rotatable within the extension drive member housing.
