Abstract: Apparatus for raising a conveyor above the surface of a poured concrete structure as the structure is formed includes a post moveable in a vertical direction that supports a conveyor on top of the post. A horizontal support tube is connected to the post, as well as a collar. A jack engages the support and raises the post and collar. A hydraulic means then places a base around the post below the collar so that when the jack is lowered, the conveyor, post and collar are supported by the newly placed base, thereby raising the conveyor relative to the surface of the structure.

Abstract: A concrete finishing machine having a movable framework mounted transversely over a paved area and defining an axis. A carriage is movably attached to the framework and has means for moving the carriage along the length of the framework. The carriage carries at least one rotating auger unit having leading and trailing portions mounted on one shaft and a finishing member. The auger unit has a leading portion having a helically arranged blade with an outer edge that is positioned in a fixed, spaced relationship with a desired grade. The trailing portion has a helically arranged blade with a band attached thereto to spread forward the excess concrete left by the leading portion and to finish the concrete at the desired grade. Plunging concrete vibrators are placed adjacent the auger unit leading portions.

Abstract: Apparatus for conveying concrete mix to distant, elevated points includes a two-segment discharge conveyor with its outer segment suspended from a movable trolley that is mounted on the boom of a cantilever crane. The segments are pivotally joined and the discharge point of the outer segment may be positioned by swinging the boom and first conveyor and driving the trolley along the boom.

Abstract: An auger hopper for transferring cementious material or the like from a supply source such as a cement truck or dump truck to a conveyor belt. A hopper is provided together with a frame for permitting the hopper to straddle and attach to the conveyor. An auger is floatably mounted for rotation within and near the bottom of the hopper. The hopper and conveyor are movably mounted on wheels. Means for mounting at least one of the wheels is provided by which the attitude of at least one wheel mounting means may be varied in relation to the hopper and conveyor. The auger operates to drive cementious materials from the ends of the hopper toward the center and then to discharge the cementious material through a discharge opening at the bottom and onto the conveyor belt without plugging the hopper.

Abstract: In a multiple, variable length conveyor system having at least two conveyor frames, one conveyor frame movable parallel to the other frame, a single, slack-free conveyor belt is positioned in combination with both frames and passes in a continuous loop forward from the back of the top conveyor to the front thereof, back from the front of the top conveyor to the back of bottom conveyor, forward from the back of the bottom conveyor to the front thereof and back over the front of the top conveyor to the back thereof to complete the loop. This single belt system permits relative movement between the conveyor frames from a collapsed state to an extended state and obviates the need for separate conveyor belts for each conveyor frame. This system is particularly applicable to multiple, variable length conveyors for conveying concrete such as multiple conveyors positioned above the extendible boom of a crane-type wheeled vehicle.
