A power sweeper has a handle having a first end graspable by a user and a second end, a drive shaft extending along the handle, and a power head coupled to the handle to rotate the drive shaft. A gear box is coupled to the drive shaft adjacent the second end, and a brush is coupled to the gear box for rotation in response to rotation of the drive shaft. The power sweeper includes an axle, and first and second wheels coupled to the axle. A shield is coupled to the gear box and defines an aperture through which the handle extends. The axle is moveable with respect to the shield and the brush to adjust an angle between the handle and the ground surface.

Power sweeper

A variable length drive shaft for a rolling mill roll including: a driven first end including a universal joint connecting with an end of a first splined shaft having an axial bore and counter bore and a driving second end including a universal joint connecting with a torque tube and a second spline shaft which engages with the first splined shaft for axial movement. A pilot rod is mounted in the counter bore adjacent to the end of the first splined shaft and extending along the length of drive shaft. A reaction tube is connected with the driving end and located within the torque tube. The reaction tube allows movement of the pilot rod within the drive shaft. Disk springs are mounted on the pilot rod and exert outward pressure against the driving and driven ends while allowing axial movement of the drive shaft.
