  • Patent number: 8137026
    Abstract: A rotating cylinder cement screeding system having a drive assembly and handle at one end for powering and controlling the screeding system. The rotating cylinder may be defined by one or more tubular screed roller sections of varying lengths, thereby allowing a user to customize the length of the system to match a specific cement pour. Further, each tubular screed roller section may be supplied with a male and female end for interlocking with each other and for receiving a variety of add-on attachments. At least one riser assembly may be interconnected to a drive assembly end and/or a non-driven end of the rotating cylinder cement screeding system. The riser assembly may elevate the rotating cylinder a distance above a finished slab to prevent the rotating cylinder from contacting the finished slab during a screeding operation.

  • Patent number: 7621694
    Abstract: A curb forming machine for use by a single operator to form curved curbing includes a single rotatable curb-forming roller, a handle assembly for pulling and maneuvering the roller, and a motor for rotating the roller. The roller includes a generally cylindrical body, a neck at one end of the body, and a shaping surface, all of which are coaxial. The motor rotates the roller so that the lower periphery of the roller moves toward the direction of pulling to shape and smooth wet concrete into curbing. An overflow guard prevents wet concrete from flowing over the roller onto the finished curb, and an alignment device extends outwardly from the roller to contact a form member. A curb forming method includes pulling and steering such a roller around a curved form, including around tight curves in the form.

    Abstract: A compactor module is adapted to be attached to a tractor module to form a complete unit. Eight pneumatic tires support the rear portion of the compactor. An emergency or parking brake is attached to each compacting wheel. The brakes are interconnected by a continuous cable and pulley control system. All brakes are applied in unison when the cable tension in the control system is increased, due to the retraction of a piston rod of an air cylinder connected to one end of the cable. The rod retracts when the pressure in the air cylinder falls below a certain predetermined level. The rod projects outwardly when the pressure in the air cylinder returns above the predetermined level. The tension in the control system is relaxed when the air pressure in the cylinder again rises above the predetermined level, the rod returns to its extended position, and the brakes are substantially simultaneously released. The other end of the cable is attached to a winch.
