homely ^w Z "-shaped and arranged at horizontal and vertical intervals of 18 inches in the wall space by embedding in the mortar joints.

Erecting such a cavity wall by hand is difficult in that the individual walls are separated from one another and must therefore be brought into alignment individually · In addition, care must be taken that the mortar applied nothing falls into the space between the individual walls · Even a very slight layer of mortar on one of the metal brackets could possibly lead moisture τοη of the outer to the inner wall and create a damp spot on the inner surface of the finished wall

The main advantage of this cavity wall is that, eoftrn it is built correctly, the inner surface of the inner wall has to be painted or directly covered with wallpaper.

By mechanically erecting such a cavity wall, a misalignment can be avoided far more easily, since the stones extremely precisely arranged by the machine and both walls are listed in parallel and at the same level.

Here is an important feature to be noted. The type, size and weight of the stones used determine the friction between the stones 34 and the surface of the slide 32 depending on the angle of inclination of the slide. To minimize the friction component of the brick against the chute To restrict, the slide angle is therefore adjustable. The angle of inclination of the slide is preferably adjusted around the axis of the cam 36. The bottom and walls of the slide can, in whole or in part, with anti-friction strips 32-a of any one suitable plastic such as polyamide plastic or the like be occupied. These. Chute feed makes it possible to use a carrying tong full of stones immediately-give up on the slide, like Fig. 13 shows.

The correct working height for each layer or row of bricks is determined by a vertically displaceable platform 46, which carries the equipment for the removal of the bricks from the elevator and the transfer to the brick laying devices arranged at the level of the corresponding brick layers of the wall. On the Stage 46 also houses the control and operating device for the means for removing the bricks from the elevator »Next the stage carries a funnel with a mortar rat and

909837/0098

also serves to make this funnel so over every brick layer to ensure that a layer of mortar is applied for the next brick layer.

The stage 46 also carries the various devices for the correct arrangement and subsequent tamping of the bricks to achieve perfect, full-surface contact between the undersurface of each brick and the layer of mortar below that undersurface and at the end faces.

The various parts of the devices placed on the stage are briefly mentioned and then each element is described in more detail with reference to the individual figures.

As FIG. 1 shows, the stage 46 is suspended from suitable cables 48 running over cable pulleys 50, which are wound up by a shaft 52 which can be rotated by means of a handwheel 54. A counterweight 56 located at the rear of the machine is used to rebalance the stage in any position to which it is moved . In addition, means are provided to hold the stage in such a position. These will be described later.
