put in motion by the Lever I. ; a Slide L. which is elevated or 

 depressed by the Lever M. In order to press a biick, the piston 

 is drawn back, as is represented in Fig. 1. The brick is put into 

 the space at S. The piston is brought forward by bringing down 

 the pinion lever G. — this permits the end of the [perpetual lever, 

 which before rested on the end of the rack, to fall into the socket 

 at K. The foot is then placed upon the lever 1. which, together 

 with the power applied to G. gives an itnmense pressure. vVnen 

 the foot is removed the weight of the Ball at N. brings up the lever, 

 which, also, by an apparatus described below, elevates the end of 

 the knuckle-joint. 



The foot is imniedialcly placed upon the lever M. which raises 

 the slide L. and the brick is pushed forward !.;. bringing the lever 

 G. still further down, and the brick is left on a boarn at P. The 

 foot is then removed from M. The slide L. falls by its own weight 

 — the piston is brought back by means of the pinion lever F. G. 

 and the machine is ready for another brick. 



Fig. 2, represents the apparatus for raising the knuckle-joint. 

 N. is the Ball, at the end of the lever I. O. a tlat Chain, passing 

 over a Pulley R. which is fastened to a Wire T. which is also 

 fastened to one end of the angular lever U. When the ball frills, 

 it pulls the end of the lever U. towards it, and the other extremity 

 moves the contrary way, and by striking against the arm of the 

 perpetual lever H. raises it in such a manner, that it slides over 

 the end of the rack E. and vice versa. 



The particular Improvements which are claimed, aside from the 

 general combination of powers, are, 



1. The mould is made to flair, or, in other words, it is some- 

 what wider at the mouth, where the piston stanVis in the drawing, 

 than at the place where the brick is, when the pressure is given. 



2. The detatching or lifting the lever, or knuckle-joint H. and 

 the apparatus tlierefor. 



3. The mode of moving the brick from the mould, after being 

 pressed. 



4. A greater length, both of perpetual lever and the finger lever, 

 which passes over the knuckle — it being extended any required 

 length.
