of the cylinder, is the pressing screw, which consists essen-
tially of a cone, with a continuous spiral thread or blade
wound around it, like the ordinary gimlet-pointed wood

of a little water. The hopper is circular, larger at the bot-
tom than at the top, and enters the large end of the cylin-

The projection of this blade from the cyl. inder gradually increases, and its pitch is the length of a brick; so that when the cylinder revolves the blade will cut the stream of clay into lengths which cannot be greater than its pitch, and can be less only when the speed of revolution is too fast relatively with the speed of the stream. The coincidence of these speeds is ingeniously accomplished by using the pressure of the stream against the blade as a means of governing the speed of revolution. Arrangements are made to prevent any damage from the accidental presence of stones in the clay. After the bricks are cut off they are carried on an endless belt under a dusting-machine, to put them in better condition for handling and to improve the surface when burnt. They are taken from this belt by

The machine of George S. Tiffany of London, Canada, is a horizontal expressing pug-mill, embodying the novel feature of two 2-bladed screws behind the die, revolving in opposite directions. The design of the machine is shown by the drawings. Fig. 10 is a perspective view; fig. 11, a central longitudinal section, taken vertically.

It revolves about six times as rapidly as the mill-shaft, and in an opposite direction, the objects being to reduce the strain on the mill-shaft and to confine the pressure by which the clay is forced through the die more nearly to the area of the die. The gear-wheels are on the driving-shaft, to which motion is given by the band-wheel U, fig. 10. The device for cutting off the bricks from the bar as it issues from the die is shown in figs. 10 and 11. The bar is first received upon the carrying-band P, and thence passes to the rollers on the rack of the cutting-table. The rack rests on rockers 1 r, which permit it to have a reciprocating motion to and from the forming.
