Abstract
Abstract A jig for precasting a multiplicity of panels, one against another, and a demountable panel precasting plant containing a multiplicity of such jigs set in succession to form a precast wall panel plant are disclosed. Each jig comprises a fixed end wall for shaping the back face of the initial panel, a movable form in which the front face and side walls are shaped and a jig base on which the movable form reciprocates. The jig base may be a concrete slab bounded at its side edges by a pair of beams which serve as tracks for the movable form. A row of columns alongside each side of the jig base supports a cross beam to which the movable jig may be locked at the successive locations along the jig base corresponding to successive panel thicknesses so that each jig may cast panel against panel with the back face of all panels other than the initial panel formed against the front face of the previously cast panel. The movable jig may also be locked to the tracks.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
182 words
A jig for precasting a plurality of panels, one against another, which comprises: a. a fixed end wall against which the back face of the initial panel is cast; b. a wheeled movable form adapted to shape the panel sides and front face, the wheels being at the side edges of said movable form; c. a jig run on which said movable form reciprocates, said jig run comprising a continuous base slab, a portion of which serves to form the panel bottom of each successive panel; d. a track bounding said base slab at each side edge thereof, the wheels riding on said tracks; and e. means to which said movable form is locked while a panel is cast, said means further including positioning elements so that said movable form may be locked in place at successive locations along the length of said jig run corresponding to successive panel thicknesses, permitting thereby casting of panel against panel wherein the back face of all panels other than the initial panel are each formed against the front face of the next previously cast panel.

A jig for precasting a plurality of panels, one against another, which comprises: a. a fixed end wall against which the back face of the initial panel is cast; b. a movable form adapted to shape the panel sides and front face; c. a jig run on which said movable form reciprocates, said jig run comprising a continuous base slab, a portion of which serves to form the panel bottom of each successive panel; d. means to which said movable form is locked while a panel is cast, said means further including positioning elements so that said movable form may be locked in place at successive locations along the length of said jig run corresponding to successive panel thicknesses, permitting thereby casting of panel against panel wherein the back face of all panels other than the initial panel are each formed against the front face of the next previously cast panel; and e. a beam bounding said jig run at each side edge thereof, each said beam including thereon spaced apart locking and positioning elements which constitute at least a portion of the locking and positioning structure which secures said movable form when casting panel against panel.
Claim 4
Dependent Claim
197 words
A jig for precasting a plurality of panels, one against another, which comprises: a. a fixed end wall against which the back face of the initial panel is cast; b. a movable form adapted to shape the panel sides and front face; c. a jig run on which said movable form reciprocates, said jig run comprising a continuous base slab, a portion of which serves to form the panel bottom of each successive panel; d. means to which said movable form is locked while a panel is cast, said means further including positioning elements so that said movable form may be locked in place at successive locations along the length of said jig run corresponding to successive panel thicknesses, permitting thereby casting of panel against panel wherein the back face of all panels other than the initial panel are each formed against the front face of the next previously cast panel; and e. a beam bounding said jig run at each side edge thereof, each said beam including thereon spaced apart locking and positioning elements which constitute at least a portion of the locking and positioning structure which secures said movable form when casting panel against panel.
