There are two cases to be considered: (1) when the drying-places are on the ground-floor, on the same level as the machines; (2) when they are in storeys.
In this case the transport is effected by means of barrows and waggons. The barrows, which are of a special shape, are made of wood (Fig. 180) or of iron (Fig. 181); they consist of an inclined platform on which the bricks are placed, either flat or on edge, in rows separated by spaces of a few centimetres.
When the bricks are made of fairly firm paste, other rows may be placed on the first, but the first must be sprinkled with sand, otherwise the bricks will stick together. Each barrow takes from 30 to 50 bricks, according to their dimensions. The barrows may have one wheel or two.

Whenever the production is fairly large, it is advisable to substitute waggons for barrows.
Rails of 0.40 or 0.50 metre gauge are laid down in the drying-sheds, and at the end of the shed a line of rails is placed, at right angles to the other, and carrying a transfer trolley (Fig. 182), which is more economical and more quickly worked than a turn-table.

This arrangement is particularly advantageous in combined sheds (Fig. 175); it is at the same time useful for carrying away dry products.
The waggons used consist of a simple framework (Fig. I 84) on which is placed a wooden platform. To push the waggon, an iron rod is fixed to one end of the frame. The waggons used for transport of dry and fired bricks may also be employed (Fig. 183). The only difference is that these have two sheet-iron ends to the platform. The bricks should be made of fairly firm paste, so that several layers may be taken.

If soft paste is used for manufacture, it is better to employ waggons with shelves (Figs. 185, 186) which allow of about 500 bricks being carried on planks. These waggons are also useful with cutting-tables with side removal (Figs. 145, 146).
All that is required is to carry the board, with the bricks on it, from the table to the waggon; labour is thus much simplified.
The same waggons are also used for drying in galleries; the spaces at the centre of the waggon and between the planks allow the hot air to pass and so assist desiccation.

In this case the products have to be transported from the machines to the different storeys of the drying-sheds. Therefore the use of lifts is indicated. These may be arranged for carrying full barrows and waggons; they are then ordinary lifts of large size. They work satisfactorily but require much power. Hence it is preferable to use lifts which raise the bricks direct (Fig. 187). On the different storeys boys remove the bricks and place them on barrows or waggons for transport to the various parts of the drying-rooms.
The trays being hung so that they always remain horizontal, a brick may be overlooked without its upsetting in passing over the top of the lift.
The wheels of the lower drum are adjustable, so that a proper degree of tension can always be given to the endless chain. This lift is placed close to the cutter of the machine, and the bricks are thus passed direct to the trays.
