Abstract: A continuous vertical the ground-excavating arrangement which comprises a guide post for being driven vertically into the ground deeper than the desired excavation depth so that said guide post can stand independently of excavation, a lower earth loading mechanism slidably secured to the guide post, a lower earth loading mechanisms, a vertical conveyor including an endless chain and conveying containers, and a horizontal earth discharging mechanism secured to the top end of the guide post. The lower earth loading mechanism includes means for securing cut ends of the endless chain for ease in adding chain links to the endless chain as the lower earth loading mechanism is periodically moved to lower excavating depths.

Abstract: A continuous vertical the ground-excavating method which comprises driving a guide post vertically into the ground deeper than the predetermined depth of excavation so that said guide post can stand independently of excavation, fixing a lower earth loading mechanism to a desired part of said guide post by using slidable securing means, excavating the ground and placing the excavated earth onto said lower earth loading mechanism, carrying up the excavated earth vertically from said lower earth loading mechanism by a conveyor system comprising endless chains and conveying containers, and further carrying the earth along an upper horizontal earth discharging mechanism secured to the top end of said guide post so as to extend horizontally, lowering said lower earth loading mechanism by a distance equal to the depth of the ground excavated, then cutting the endless chains and adding complementary endless chains while mounting supplementary conveying containers, and repeating said steps the required number of times

Abstract: A continuous conveyance system comprising a series of ship-shaped conveyance containers whereby bulk load is conveyed, two pairs of endless chains adapted to support and carry said conveyance containers at both front and rear portions thereof, said pairs of endless chains consisting of a pair of inner chains adapted to carry the front portion of each said container and a pair of outer chains adapted to carry the rear portion of said container, chain wheels around which said endless chains are passed, said chain wheels consisting of the inner chain wheels around which said inner endless chains are passed and the outer chain wheels around which said outer endless chains are passed, said both inner and outer chain wheels being secured to a common shaft at the rotatory section where the bulk load is received, the rotatory section where bulk load is dropped and the rotatory section where the direction of movement of the conveyance container is merely changed by 90.degree.
