Abstract
Abstract A trackway with horizontal forms between the rails for use in casting building wall sections from cementitious materials has a rail mounted apparatus that straddles the forms and is used for storing and dispensing the cementitious materials into the forms. The apparatus is self-propelled and has a plurality of open top bins that are mounted on a horizontally movable carriage beneath a hopper that is used to receive and discharge the cementitious materials into the bins. The carriage is mounted on a vertically movable frame that is suspended from an open box-like frame component of the apparatus. The bins have narrow elongated bottom discharge openings that are transversely arranged to dispense the materials into the forms and the openings are equipped with gates that are independently opened and closed by hydraulically powered cylinders. Hydraulically powered cylinders are used for horizontally moving the carriage and for vertically moving the supporting frame for the carriage and a vibrating assembly that has a shoe for floating concrete in the form is supported and movable with the carriage and is also equipped with means for vertically moving the assembly with respect to the carriage. The vehicle-type apparatus is also equipped with compartments for storing fluids that are dispensed through suitable nozzle equipped headers that are either mounted on the body frame of the apparatus or on the vertically movable frame.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
268 words
The combination comprising an elongated trackway having spaced apart parallel rails, a plurality of open top horizontally arranged forms that are located in the space between said rails and spaced apart along the trackway for use in casting vertical wall sections from cementitious materials, and an apparatus for storing and dispensing said materials into said forms, said apparatus comprising a rigid body frame having a bottom portion and a top portion which is vertically spaced from said bottom portion, wheels rotatably mounted on said rails and supporting said body frame over the space therebetween, a rigid frame mounted on said body frame and vertically movable between the top and bottom portions thereof, a carriage supported on the vertically movable frame, said carriage being horizontally movable on said vertically movable frame and in parallel with said rails, a plurality of elongated bins arranged transversely of the trackway and mounted on and movable with said carriage, each of said bins having an open top portion for receiving cementitious material to be stored therein, an elongated transversely arranged narrow bottom opening for discharging the stored cementitious material into said forms, and a gate movable between open and closed positions with respect to the bottom opening of the bin, said apparatus further comprising manually controllable powered means secured to the body frame for vertically moving the vertically movable frame, manually controllable powered means secured to the vertically movable frame for horizontally moving said carriage on said vertically movable frame, and manually controllable powered means supported by and movable with the carriage for moving the gate between the open and closed positions therefor.
Claim 2
Dependent Claim
268 words
The combination comprising an elongated trackway having spaced apart parallel rails, a plurality of open top horizontally arranged forms that are located in the space between said rails and spaced apart along the trackway for use in casting vertical wall sections from cementitious materials, and an apparatus for storing and dispensing said materials into said forms, said apparatus comprising a rigid body frame having a bottom portion and a top portion which is vertically spaced from said bottom portion, wheels rotatably mounted on said rails and supporting said body frame over the space therebetween, a rigid frame mounted on said body frame and vertically movable between the top and bottom portions thereof, a carriage supported on the vertically movable frame, said carriage being horizontally movable on said vertically movable frame and in parallel with said rails, a plurality of elongated bins arranged transversely of the trackway and mounted on and movable with said carriage, each of said bins having an open top portion for receiving cementitious material to be stored therein, an elongated transversely arranged narrow bottom opening for discharging the stored cementitious material into said forms, and a gate movable between open and closed positions with respect to the bottom opening of the bin, said apparatus further comprising manually controllable powered means secured to the body frame for vertically moving the vertically movable frame, manually controllable powered means secured to the vertically movable frame for horizontally moving said carriage on said vertically movable frame, and manually controllable powered means supported by and movable with the carriage for moving the gate between the open and closed positions therefor.
Claim 3
Dependent Claim
51 words
The combination in accord with claim 1 where said apparatus comprises an assembly supported by and movable with the carriage for use in floating concrete in said forms, said assembly comprising an elongated transversely arranged shoe receivable in the open tops of said forms, and powered means for vibrating said shoe.
Claim 4
Dependent Claim
29 words
The combination in accord with claim 2 where said apparatus comprises manually controllable powered means mounted on said carriage for vertically moving said assembly with respect to said carriage.
Claim 5
Dependent Claim
