The upper end of said forms a valve-seat L1, which is provided with cylinder, upon one side thereof, is provided a series of circularly-arranged apertures 5, with a supplemental boxing or casing 23, that roo 5o that are adapted to be normally closed by the is adapted to accommodate the transverse upwardly-opening spring-pressed valves 5, shaft 24, journaled in the sides thereof, and to sa'` esac-ra which are secured the arms or rods 25, carrying at theirinner ends Within said cylinder the floats 26 that are adapted to rise and fall with the rise and fall of the water within the cylinder. The said shaft 24 projects without the sides of said casing 23 and through the ordinary packing or stuiiing boxes 27 and is adapted to receive the double bell-crank levers 28, the upper ends of which are connected by the transverse rod 29, `upon which is mounted the friction contact-roller 30, while the outer ends or arms of said bell-crank levers are adapted to receive `the laterally-adjustable Weights 3l, working thereover, aud

Mounted upon the rod or stem 37 and within the cylinder 33 is the float-cup 3.9,that is adapted to rise and fallwith the rise and fall of the water in the adjacent cylinder l, and thereby vertically reciprocates said stem. To the upper end of said stem is connected a cross piece or bar 40, from which depends the opposite 'parallel arms 4l, working in the bearing-plate 42, secured to said tube 34, and said arms are adapted to receive thetappets or collars 43, mounted thereon and carried by the reciprocation of the stem 37. A tilting lever 44 is pivoted centrally at 45 to the U-shaped casting 4G, supported upon the cylinder 1, and is provided at its lower end with the friction contact-roller 47 and the inwardly-proj ectin g stud or roller 48, that is designed to travel in the segmental slot 49, located in said U-shaped casting, and by means of which the movement of said tilting lever is limited. An adjustable weight 50 is mounted upon the upwardly-extendin g end of said arm or lever and is adapted to throw the same sharply to the right or left after said lever has assumed a vertical position in the manner to be presently described. The main valve-operating rod 51 is supported upon and horizontally over the top of the cylinder l and is connected at one end to the arm of the double bellcrank lever 52, pivoted upon thebracket 53 at one end of said cylinder, and said bell-crank lever is provided with the connecting frictionroller, similar to roller 30, that is designed to be engaged by the tappets 43, carried by the reciprocating stem 37, and thus causes the said valve-rod 51 to be controlled from that side of the cylinder in one direction. The opposite end of said lever or arm 5l is provided withJthe downwardly-extending tappet 55, that is designed to be engaged by the roller A branch 30 upon thedouble bell-crank lever 23 when the floats have been carried to a horizontal position, and thusdraws said rod in an opposite direction to that in which the same is drawn by the tappets 43. The said lever or arm 51 is further provided with the intermediate tappets 56 and 56, respectively, between which the `contact-roller 47 ofthe tilting lever 44 is designed to travel, and accordingly as said rod or lever 51 is moved in either direction the said tappets carry the tilting lever 44 in a vertical position, in which position the weight 50 thereon overbalances the same and throwsthe lever sharply to the right or left, according to `Whether the lever or rod 51 is reciprocated to the left or right, and the sudden tilting movement of said weighted lever sharply reciprocates the small valve-arm 57, pivotall y secured at 58 near the lower end of the tilting lever 44, and carries the spaced tappets 59 and 59, between which the balance Valve-lever 60 depends and carries the contactfriction-roller 61, which is engaged by either of the said tappets, according to the direction in which the tiltinglever falls, and thus opens the balance steam-valve 62, operated by said lever and located in the steam-pipe 63,communicating with the steamopening 22, located in said cylinder directly over the diffusion-plate 21. The said steampipe 63 is connected with any suitable generating-boiler, and is further provided with a supplemental hand-operated balancevalve 64, by means of which the steam is let on and entirely shut oit at the option of the operator. The cylinders l may be duplicated, if desired, and connected with asingle Water supply pipe by suitable connection for the purpose of obtaining an increased volume of Water, if desired.

The operation of the pump is automatic after the same has once been started by the operator. Primarily the cylinder 1 is filled with a sufficient quantity of water in order that the level of the same, may be above the inlet spray-pipe 14, so that Water will stand within the same within the cylinder. The steam is now let on by the operator through the hand-operated balance-valve V64, located in the steam-supply pipe 63, and the lever 60 of the balance-valve 63 is turned by hand, so as to give a free passage of the steam to within the cylinder. The steam filling the cylinder completely is almost instantly condensed by the spray-condenser 18, thus completely IOO IIO

filling the cylinder with Water and bringing the oats 26 up toV a horizontal position, thus communicating motion through the bell-crank levers 23 to the horizontal arm or lever 5l by means of the contact-roller 30 of said bellcranks engaging the tappet 55 on said rod or arm, and through the smaller intermediate tappets 56 and 5,6, engaging thelower end of said tilting lever,causes the same to be sharply thrown to one end of itslimit of movement, and thus starts the automatic operation of the pump. It can be readily seen that after the 'tilting lever has been caused to assume a vertical position the weight ofthe ball or otherl tact-roller 6l upon the e'nd ofthe valve-operating lever 60, thus opening the passage-ways and allowing the steam or other vapor'which may be used for creating a vacuum to pass immediately into the cylinder, and, as can be readily seen, this primary operation causes the valve-operating part to assume a position holding the same open while the cylinder is full. The steam being thus admitted into the cylinder impingcs on the concaved diffusion-plate and is equalized over the entire surface of the water in the cylinder, which under the pressure of the steam is forced downward and out through the discharge-outlet 6, through the valve-chamber thereover, and out through the discharge-pipe 12 to the place of delivery. The water being now discharged, the iioats 26 have descended to their lowermost limit and carried the bell-crank levers 23 away from the tappet 55 on one end of the horizontal rod 5l, thus leaving the rod free to be acted on by the vertically-reciprocating tappets 4:3, engaging the double bellcrank levers 52, secured to the opposite upper end of the cylinder and connected to the 0pposite end of said rod. The opening communieating the cylinder 33 with the main cylinder 3l governs the discharge of the water, inasmuch as the cup 39 located therein falls with the fall of the water, and when the water has fallen its allowed limit the said cup also has fallen with it and carries the stem or rod 37 downward, and thereby causes the tappets 43 4to iinpinge upon the roller of the bell-crank levers 52 and draw the operating-rod 5l in the reverse direction, or to the right, as illustrated in the drawings. rlhe tappet 56 upon said rod 5l now carries thetilting lever to a vertical or perpendicular position, at which point the same sharply falls to theleft, or the reverse direction from which it fell to open the steam-valve, and thus carries the tappet 59a upon the valvelever or arm 57 to the right' and against the lower end of the valve-lever 60, thus throwing the same to its vertical position, in which the ports or steam-passages are instantly closed. The water in the cylinder having been thus discharged to its allowed level, the steam is thus shut off through the medium of the float-cup 49 in the manner just described, and leaves the cylinderlcornpletely illed with the steam or vapor. The4 instant the steam or Ivapor is shut off the pressure of the water in the discharge-pipe l2, extending above the top of the cylinder, forces its way into and through the conductingpipe4 and upward through the perforated pipe 17 into the spray-condensing chamber 18 and through the radially-extending perforated s'pra'y-arm 19, the column of water n ot only giving force to spray the same within the cylinder, but the spraying is also accelerated by the uvacuum Vinstantly formed at the closing of the'steam-valve. again filled by the watersucked within the same by the vacuum through the suction-pipe 2 and suction-chamber 3, and the alternate automatic operations of the pump are repeated in the manner j ust described,
