Fig. 1 is an end view of the machine^, and fig. 2 a section on 

 the line a a. In these figures, the letters refer to the correspond- 

 ing parts in both figures. A is a box or mould of cast-iron fixed 

 by hook joints at the corners, and bolted to the frame B^ .also of 

 cast-iron. The box is 13^ inches long, 10 inches wide, and 6 

 inches deep, but may be varied in size, according to the size of 

 tile wanted. It is fitted with a movable bottom or piston, which, 

 being attached to the rack-bar C, rises and falls with it. The 

 rack-bar is acted upon by a pinion fixed in the shaft D, supported 

 in the frame-work. This shaft D carries also a spoke-wheel E, 

 having eight bent spokes or hands^ by which the operator acts 

 upon the machine. 



To work this machine properly, one man and two boys are 

 required. The man stands on the side of the machine with his 

 right hand towards the spring-stop F ; one boy between the 

 machine and the table on which the bending-blocks or horses are 

 placed, and the other boy behind the table. The man having let 

 down the piston to its lowest point, takes a lump of clay of 

 sufficient size ; this he throws with force into the mould ; if it 

 does not fill up all the angles, he beats it in with the blow of a 

 mallet, and with the strike or bow, Fig. 3, cuts off any superfluous

clay that may stand above the edges of the mould, smooths the 

 clay with the same, turns the wheel E one spoke round, which.
