Abstract

1,225,373. Brick-laying apparatus. P. M. THOMAS. 14 May, 1968, No. 22777/68. Heading EIS. Horizontal brick, &c joints are formed using e.g. a clamp (Fig. 3) or a supporting tray (Fig. 11) to hold the brick mechanically, virbrating the mortar bed, using, e.g. vibrators 10 on the clamp or vibrators 43 on the tray, and locating the bricks at the correct level using the supporting surface for the first brick course as a datum. The tray is used to support bricks 37 with vertical mortar layers 39 therebetween, and a mortar layer 38 thereon, the tray being lowered by a frame 41 with prongs 46 thereon which press the bricks down. When the bricks 37 are at the desired height, slides (45), Fig. 12 (not shown) are withdrawn, to which the horizontal fingers 40 forming the tray are attached. Vertical mortar layers can alternatively be formed independently of the horizontal layers using a hopper (16), Fig. 4 (not shown) with vibrators attached, in combination with stirring rods (23) attached to a further vibrator (18), or in combination therewith using a similar hopper (26), Fig. 8 (not shown) with a rear extension (31) to form the horizontal layer. A hopper for laying horizontal mortar layers only is illustrated in Figs. 1 and 2 (not shown).
