Abstract

A powered concrete screed apparatus comprising a roller rotatably attached to a chassis. The chassis includes an elongated member that extends in spaced, parallel relation to the roller, and is of substantially the same length as the roller. The elongated member is attached to the roller at one end by a motor removably mounted thereto and which includes gears extending therefrom which are operatively attached to the roller, and at its opposite end by a plate which extends between the tubing and roller. A pair of handles are mounted to and extend upwardly from the tubular member, and are independently, slidably adjustable along the length of the tubular member. The handles are also telescopically adjustable, thereby permitting their lengths to be selectively controlled. A throttle is removably attached to one of the handles and electrically connected to the motor, thereby permitting selective control of the power output from the motor. The screed apparatus also include a pair of wheel assemblies attached to the tubular member at opposite ends thereof. The wheel assemblies permit the apparatus to be easily moved to and from a worksite without damaging the roller.

Dependent claims

An apparatus for screeding concrete, comprising:

a) an elongated chassis having first and second opposed, terminal ends, and extending along a first longitudinal axis;
b) an elongated roller of predetermined diameter rotatably connected to said chassis, said roller including first and second open, opposed, terminal ends, said roller extending in spaced parallel relation to said chassis along a second longitudinal axis;
c) motor means mounted to one of said first and second terminal ends of said chassis;
d) gear means operably interconnecting said motor means to said roller, whereby actuation of said motor means causes said gear means to effect rotation of said roller about its said second longitudinal axis;
e) first and second elongated arms attached to and extending perpendicularly outwardly from said chassis, and in spaced, parallel relation to one another, said first and second arms each including at least one hole formed transversely therethrough, with said at least one hole formed through said first arm being positioned in axially aligned relation with a corresponding one of said at least one hole formed through said second arm;
f) a mounting block securely attached to said motor means, said mounting block having at least one hole formed therethrough which is positioned in axially aligned relation to a corresponding one of said at least one holes formed through said first and second arms;
and
g) means for fastening said mounting block to said first and second arms.
