Abstract: 161,824. Chedburn, N. S., and Chalmers, W. R. March 29, 1920. Walls; wall-ties. - Walls are moulded section by section and course upon course by the use of uprights j secured by transverse bolts c passing through tubular ties d embedded in the concrete already set, and sliding moulds or shutters. The uprights which are recessed at the top ends are adapted to support horizontal members g<2> carrying a rail g<1> on which slides a movable mould, or to support sliding shutters g<20>, Fig. 21, which may carry a movable core for use in moulding hollow walls. The movable mould is formed with sides of different lengths hinged at one end to a front plate and adapted to receive at its other end a removable back plate carried by a transverse bolt c. This bolt is positioned at the spacing of a course above the, top bolt already in the concrete to support the uprights, and is aligned by means of a stop h contacting with the upright j. The sides of the mould carry sliding bolts which, after the mould is positioned, enter a recess between a vertical flange of the guide rail and the side of the mould to secure the mould in position. When a vertical waterproof course b is used in the wall, means to position the course are provided on the two ends of the mould, the bolts c and ties d passing through holes in the course. The ends of the horizontal supports are formed, one with an angle connecting plate g<3>, Fig. 16, and the other with a recessed end g<4> and a bolthole g<6> so that the ends may be joined, Fig. 17. For forming angles, angle rails are provided and also horizontal supports A, A<1>, Fig. 19, adapted to be hinged at A<3> to the free ends of the mould. the internal support A<1> being secured to an upright J by transverse bolts c.
