Similar letters in the several figures refer to cor- 

 responding parts. 



A is the main pipe for conducting the propel- 

 ling water from the head, or reservoir, to the 

 pyramidal air-chamber. The pipe descends be- 

 low the level of that portion of it which connects 

 with the air chamber just before it reaches the 

 said chamber, and then ascends in a curved line 

 to it, forming a curved bend in the pipe, as at A\ 

 for the purpose of preventing the air received 

 at the valve B, during the time in which the 

 vacuum is produced in the air and water cham- 

 ber, as hereafter described from filling the pipe 

 A, as the air will not descend at said bend in the 

 tube, so that tlie surplus of said air. after having 

 filled the condensing chamber L, may be carried 

 off by the current of water through the valve B. 



The pipe A is enlarged below the air chamber 

 L, as at A2, and has an opening O into the air 

 chamber L, through which the water passes when 

 the valve B is closed. 



B is a valve attached to a curved, vibrating 

 lever C, turning on gudgeons D, in boxes, as its 

 fulcrum, having a set screw E, for regulating 

 the descent of the valve, and a counter balance 

 F, for adjusting the valve. When this valve B 

 is down, as shown in fig. 7, the water from the 

 head flows through the opening, which it closes; 

 when it is up, as shown in fig. 6, the water rises 

 into the pyramidal chamber L, through the open- 

 ing O, and condeses the air therein. 



H is a pipe for conveying the spring water to 



the spring water chamber. 1 is an air chamber 

 into which the water is forced. J is tlie valve 

 for holding it. K is a pipe, or hose, for convey- 

 ing the water to its place of destination. The 

 above named parts, lettered from A to K, inclu- 

 sive, are made and operated in the usual manner. 

 The improvements are as follows : 



Lis a pyramidal chamber, into whicli air is 

 admitted through the valve B, when it descends 

 by the pressure of the external air, to supply the 

 partial vacuum created in the pipe A, and cham- 

 bers L and N. 



This pyramidal chamber has a communication, 

 by a small opening M, at the top, with another 

 chamber, N, called the spring or pure water 

 chamber ; through which opening M, the air, so 

 condensed, is forced, and presses on the spring 

 or other water, introduced into the same through 

 the pipe H, by which pressure the water in said 

 spring water chamber is forced upward through 

 a tube P, i-eaching to near the bottom of said 

 chamber N, through the valve J, into the air 

 chamber I ; said valve being represented as open 

 in fig. 6, and as closed in fig. 7. 



To raise water with this machine, open the 

 valve B, the water, which is now in motion in 

 the pipe A, will pass through the opening O, 

 into the pyramidal condensing chamber L, and 

 condense the air the same as before ; the con- 

 densed air will force the spring water up the tube 

 P, (whicli had entered through the pipe H, 

 during the continuance of the partial vacuum 

 above spoken of,) into the chamber I, and con- 

 dense the air therein, until its density is equal to 

 that in the condensing chambers Land N, below. 

 At this time the spring water will cease to flow 

 into the air chamber 1, the valve .T closes, and 

 the air in the chambers I, L and N commences 

 expanding, that in the lov.er chambers, L and N, 

 giving motion to the propelling fluid and driving 

 it backward, producing a partial vacuum in the 

 machine, and ihe air in the upper chamber L, 

 forcing the spring water to its place of destina- 

 tion. The said partial vacuum in the machine-, 

 caused by the reaction of the machine, as 

 aforesaid, and the pressure of the external at- 

 mosphere on the valve B, will cause it to open 

 again. The water from the head then flows 

 through this valve with an accelerating move- 

 ment, until it has acquired that degree of veloc- 

 ity as to cause the valve to close. The water 

 having no longer any vent through the valve B, 

 passes through the opening O, into the pyramid- 

 al air chamber L, and repeats the operation 

 above mentioned, successively. 



In this manner the operation will continue as 

 long as the machine remains in order, and there 

 is a head of water to propel it. The ', alve V is 

 for the purpose of supplying the chamber I with 

 air, by almitting said air into the tube P. The 

 said air is admitted during the time that the par- 

 tial vacuum above mentioned takes place. The
