Abstract
Abstract A plant for filing molding cavities arranged in one or more bays. The plant comprises a framework of beams, a bucket mounted on the framework for horizontal displacement between a cement mixer station and a hopper. The hopper is mounted on a carriage which is displaceable in the same direction as the bucket. A conveyor is mounted on the carriage in alignment with the hopper for delivering concrete from the hopper to the molding cavities. The conveyor extends in a direction perpendicular to the direction of movement of the carriage. The entire conveyor assembly is displaceable along its own longitudinal axis between positions corresponding to the various molding cavities. The downstream end of the conveyor is fitted with a chute for directing concrete into a particular molding cavity. The operator may control the various elements such as the bucket, conveyor and carriage either from a console on the carriage or a control panel situated in the vicinity of the downstream end of the conveyor.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
163 words
A plant for filling a plurality of molding cavities arranged in a bay comprising, in combination, a framework, a mixer station operatively associated with said framework, a hopper, a bucket, means mounting said bucket on said framework for horizontal reciprocation relative to said framework between said mixer station and said hopper for delivering a mixed filling material to said hopper, a carriage carrying said hopper, said cArriage being supported by said framework and being displaceable relative to said framework in a direction parallel to the direction of movement of said bucket, a conveyor mounted on said carriage in alignment with said hopper for receiving a mixed filling material from said hopper, said conveyor having a longitudinal axis extending perpendicular to the direction of movement of said carriage, means mounting said conveyor on said carriage for movement between forward and rearward positions along its longitudinal axis relative to said carriage, and means associated with the conveyor for pouring a mixed filling material into molds.
Claim 2
Dependent Claim
163 words
A plant for filling a plurality of molding cavities arranged in a bay comprising, in combination, a framework, a mixer station operatively associated with said framework, a hopper, a bucket, means mounting said bucket on said framework for horizontal reciprocation relative to said framework between said mixer station and said hopper for delivering a mixed filling material to said hopper, a carriage carrying said hopper, said cArriage being supported by said framework and being displaceable relative to said framework in a direction parallel to the direction of movement of said bucket, a conveyor mounted on said carriage in alignment with said hopper for receiving a mixed filling material from said hopper, said conveyor having a longitudinal axis extending perpendicular to the direction of movement of said carriage, means mounting said conveyor on said carriage for movement between forward and rearward positions along its longitudinal axis relative to said carriage, and means associated with the conveyor for pouring a mixed filling material into molds.
