Patent Number Title Of Patent Date Issued
8132983 Riding concrete trowel with stabilizers March 13, 2012
In a riding concrete finishing trowel, a stabilizer is operatively disposed between the frame and either the gearbox or a structure that is coupled to the gearbox so as reduce the effects of rotor assembly vibration on the trowel. In one embodiment, the stabilizer takes the form of a
7686538 Portable vibratory screed with bubble vial inclination indication system March 30, 2010
A portable vibratory screed includes a blade that is connected to a handle constructed to be manipulated by an operator. Nodes of minimum vibrational amplitude are formed at specific locations along the length of the blade when the exciter is driven at a rated operating speed. A site
7172365 Method of making and using a dynamically balanced walk behind trowel February 6, 2007
A method is provided of making and using a walk behind rotary trowel that is "dynamically balanced" so as to minimize the forces/torque that the operator must endure to control and guide the trowel. Characteristics that are accounted for by this method include, but are not limited to,
6974277 Dynamically balanced walk behind trowel December 13, 2005
A walk behind rotary trowel is configured to be "dynamically balanced" so as to minimize the forces/torque that the operator must endure to control and guide the trowel. Characteristics that are accounted for by this design include, but are not limited to, friction, engine torque, machin
6244730 Light source with easily accessed light guide June 12, 2001
A spotlight assembly is disclosed, including a spotlight energizeable to transmit a beam of light and having a lens frame configured to support a lens, and a cylinder coupled to the lens frame and adapted to receive at least one light guide through an opening in a sidewall of the cylinde
