Abstract
Abstract ABSTRACT A scaffold mechanism for constructing a cylindrical building, such as a concrete silo, with a horizontal platform supported on a plurality of fixed arms having telescopically extensible ends with the platform vertically supported on triangular-ly positioned peripheral vertical ground supported masts having pins placed in openings for locking the platform at vertical increments and having hydraulic lifters on each of the masts for raising the platform for each pouring of new concrete courses. A ground supported main central mast extends up through the platform and supports, at its upper end, cranes which are pivotally supported on the main mast for lifting the forms to reset positions, elevating concrete to a bucket cart which rolls peripherally around on the platform, or suspending and rotating hoses used for the placement of concrete when pumping is used in lieu of elevating concrete to a bucket cart. A hydraulic motor driven pump is carried on the platform for operating the elevating mechanism, the cart and the cranes.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
222 words
A scaffold mechanism for constructing a cylindrical building such as a concrete silo comprising in combination: a horizontal generally circular platform means for distributing construction ingredients to the cir-cular wall of a silo being of a size with the edges extend-ing close to the inner silo wall; a plurality of peripherally located ground supported vertical mast means for positioning immediately adjacent the inside of the circular wall for supporting the weight of said platform means within said wall; lateral stabilizing means at the edge of the platform for engagement with the silo wall; said mast means laterally supported with lateral support afforded by engagement of said lateral stabilizing means; a separate fluid pressure operated power elevation means for incrementally raising said plat-form means mounted on each of said mast means connected to the platform and releasably lockable to the mast means; said power elevation means having a releasable lock preventing downward motion of the elevation means for raising the platform but permitting free upward movement of the eleva-tion means for stepwise resetting the height of the eleva-tion means on the mast so that said elevation means can be moved upwardly on the mast means by its own power; and locking means independent of said power means for support-ingly locking said platform means to said mast means between operation of said power means.
