Abstract: A roller carriage assembly for a road surface finishing machine of the type having an elongated main frame is disclosed. The assembly features a vibrating drum or roller wherein rotating eccentric weights used to generate vibrations can be rotated at speeds which are independent of the speed of roller rotation to thus permit the finishing of extremely low slump concrete. The assembly employs a scissors extender system which permits rapid and precise changes in the level of the roller relative to the main frame without affecting the attitude of the former relative to the latter. The scissors extender system is locked in place by a rotating locking mechanism and is rigidified by the use of four chains disposed at the corners of the system and strung between upper and lower plates between which the scissors mechanism operates.

Abstract: A method for levelling and smoothing concrete when concreting large areas. According to the method a machine which is so constructed that it floats lightly even on highly fluid concrete mass and thus normally exerts a very low surface pressure against the substratum, is caused to move over the surface of the concrete while smoothing and levelling the same as a result of rolling motion between the surface and a belt of the machine in contact therewith. The smoothing or levelling effect of the belt can be amplified by vibrating a plate supporting the belt. The concrete may also be subjected to vacuum treatment at the same time as levelling or smoothing the concrete. The invention also relates to a machine for carrying out the method.

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.

The second member includes an adjustment mechanism to accommodate different sized rolls.

Abstract: Method and apparatus for compacting a layer of material using a compacting machine having at least one drum which is rolled over the layer; the material layer is acted on by gravitational force of the roller and an oscillating force. The latter is the result of applying a rapidly substantially alternating torque to the drum about its axis. The direction of action of the torque is reversed with a high frequency in relation to the frequency with which the direction of travel of the compacting unit is reversed. The invention also embraces means for executing the method wherein the torque on the drum is provided by at least two synchronously operating, rotating eccentric means spaced from the shaft of the drum, and which are adapted such that the forces caused by their synchronous movement can substantially neutralize each other radially to the drum and co-act to form a pure torque on the drum about its shaft.

Abstract: A method is disclosed for providing optimal compaction of various materials by controlling the vibration amplitude of an adjustable amplitude vibratory roller. The vibration amplitude is automatically reduced when excessively high jolting forces are sensed by transducers carried by the roller or its frame. The apparatus for carrying out the method includes a continuously adjustable eccentric element in the vibratory roller, at least two signal transducers mounted on the roller drum or frame and axially separated, to generate signals representing the vibrational movement of the roller. A regulating system responsive to the signals from the signal transducers reset the adjustable eccentric element to vary the vibration amplitude and provide optimal compaction.

The rotor structure is mechanically balanced so that substantially no vibratory force is transmitted through the rotor shaft and bearings.

Abstract: An earthen structure for holding back a body of water has a sloped surface which is paved with an overlapping arrangement of strips constructed of castable material. Each strip is formed by conveying castable material from a mobile receiving hopper that is propelled adjacent to the base of the earthen structure. A bridge conveyor projects laterally from the receiving hopper over the slope. The bridge conveyor deposits the castable material onto the slope forwardly of a spreader device that is advanced longitudinally relative to the slope by a prime mover. A scraper blade of the spreader device is positioned at a preselected elevation by a forwardly projecting sidewall which is connected to the blade and slidable on a previously formed strip. The sidewall maintains the castable material in front of the blade, as the advancing blade spreads the material in a longitudinal strip of a preselected thickness and having a lateral edge extending a preselected lateral dimension outwardly from the sloped surface.

Abstract: A concrete slab striker employs a counter-rotating roller to grade or strike off the surface of a freshly poured concrete slab while the concrete is still in the plastic state. An elongated roller is supported on a form bordering the concrete slab in engagement with the concrete surface. A manually movable support frame and pull device coupled to opposite ends of the roller allow workmen to pull the roller across the concrete slab. Simultaneously, the roller is rotated in a direction opposite to its direction of travel relative to the surface of the concrete slab. A thin coating of hardened concrete particles accumulates on the roller to impart a texturized surface to the concrete slab when cured.
