Abstract: A plurality of annular collars are provided formed from collar halves. The collar halves are at least partially separable from one another to allow the collar halves to be slipped into and around a groove in a grooved roller for a reel-type cutting unit. The collar halves can then be abutted and secured together to substantially fill in the roller groove. When collars are placed into the last two or three grooves on each end of a grooved roller, a non-shouldered grooved roller is thereby converted into a shouldered grooved roller without having to remove and replace one set of rollers with another.

A pair of hand grips are extended from the second end of the handle member.

Abstract: A powered rotary screed provides a powered strike tube that rotates to provide a finish to wet concrete during screeding and a drive tube that provides motive power to the screed to assist with the difficult task of removing excess concrete from a poured pad, or other horizontal concrete surface. No framework or other supporting structure extends between ends of the screed thereby making the screed more portable than comparable screeds having a structure that supports the roller tubes and extends the length of the screed. Handles are pivotally coupled to plates at each end of the screed to maneuver and control the screed during operation. Because the handles are pivotally mounted, they can be pivoted outward to permit the screed to maneuver close to obstacles located near the pad.

A heat exchanger receives the exhaust gas from the internal combustion engine and transfers waste heat from the exhaust gas to the working fluid. An electric heating element is provided for converting some of the electric output of the generator into heat and transferring this heat to the working fluid. A pump circulates the working fluid through a ground-engaging heat exchanger.

Abstract: An aggregate floor including terrazzo and the like and a method for forming the floor on a supporting surface, the floor including a layer of flexible compound applied to the surface, a reinforcement mesh positioned between divider strips and adjacent the compound and supporting a layer of compacted aggregate forming a substantially level surface. The divider strips are selectively positioned in desired configurations on the flexible compound layer to divide the mesh and aggregate into discreet and crack controlled sections. A mixture of composite cement, water, and, in some cases, sand is applied to the surface of the aggregate layer in such a viscosity as to gravitate completely through the aggregate layer and make contact with the underlying layer of flexible compound. Such permeation fills and replaces the air pockets between the aggregate particles and deposits sufficient top coating on the surface of the aggregate to be polished to a finished surface.

Located on the flat table is a plurality of infrared heaters that form an oven over the flat table and which are pivotally attached to the handle for allowing the roofing paper to pass over the table and through the oven. The paper is drawn from the roll through the oven and under a pair of rollers that support the applicator.

Abstract: A vibratory roller having four drums that can be vibrated. The drums are driven individually, and are mounted in pairs in respective supports. One of the supports is attached to a front frame, and the other support is attached to a rear frame. The object of the invention is to improve the steering condition of vibratory rollers, and especially of trench rollers, in such a way that on the one hand changes in direction during normal travel, or small corrections in direction, can be rapidly undertaken without damaging the already compacted surface of the ground, and that on the other hand it is also possible to make sharp changes in direction practically on the spot. Previously known types of steering for vibratory rollers, namely fifth-wheel steering, transfer steering, articulated steering, and panzer steering, do not permit such a diversified steering condition. Pursuant to the invention, the desired steering condition is achieved by interconnecting the front and rear frames via a hinged or swivel coupling.

Abstract: A rotating tube concrete finisher is controlled and driven by an end handle assembly including an internal combustion engine. An outrigger wheel unit is coupled to the end handle assembly to form a stable end support for the end handle assembly and to support the weight of the end handle assembly including the engine. A pair of end handle assemblies can be coupled to opposing ends of a cylindrical finishing roller and may be selectively operated to drive the finishing roller in either a first or a second direction of rotation. A winch system facilitates uphill and downhill translation of the concrete finisher on a sloping concrete surface and enables the system to be operated by one man without undue effort.
