CONDENSING PATENT @erica or NEW YORK, N. Y.

APPARATUS.

SPECIFICATION forming part of Letters Patent No. 248,981, dated November 1, 1881,

Application tiled July 1, 1881. (No model.) l

To all whom lit may concern Be it known that I, `BENJAMIN T. BABBi'r'r, ot the city of New York, in the county and State ot' New York, have invented'certain new and useful Improvements in GondensingApparatus, ot'which the following is a specification.

Myinventiou relates to condensers t'or steamengines and other purposes, which are adapted to work without an air-pump, the water being discharged from the condensers against the pressure of the atmosphere by Torricellian eolumns or barometric legs.l

The invention consists in the combination of two chambers provided with steam and water inlets and with water-outlets, to which are connected Torricellian columns or barometric legs, valves in said steam-inlets and wateroutlets, floats in said chambers, andaweighted tripping lever or beam, to which the several valves are connected, and which is actuated by said floats to adjust the valves simultaneously. to provide for the alternate passage ot' steam into one chamber and the alternate discharge of water from the other chamber, whereby I provide an apparatus which is entirely automatic in its action, and which is very desirable because of its simplicity.

The accompanying drawing represents a central vertical section of the apparatus ernbodyiug my invention.

A designates two chambers, (here shown as cyliudric in form, and ot' any suitablesize, according to the quantity of steam to be condensed.) In the chambers A are iloats B, having rods B', which project upward through stut'tingboxes a in the top of the chambers, and are adapted to act alternately upon opposite ends of a beam or lever, C, which is fulcrumed or pivoted in an upright post or column, D, and is provided with an upright projection or arm, C', weighted at b. Thus it will be seen that whenA either end of the beam C is raised to shift the center of gravity to the opposite side of its fulcrum the movement of the beam will be completed by gravity.

E designates asteam-inlet pipe connecting the two chambers A, and E designates the pipe by which steam to be condensed is delivered from the engine or other machine into the pipe E. The passage ot'steam to the chambers A is regulated or controlled by valves 0,

(here shown as consisting ot' ordinary plugvalves,) which are opened alternately by rods d, which form a connection between the beam U and the levers e of said valves. The water for condensing is introduced or injected continuously through two injection-nozzles, f, and the water and steam ent-er the chambers A together' through the steam-inlets.

F designates the discharge or outlet pipes leading irom the chambers A, and communieating with or forming Torricellian tubes 0r barometrie legs, which are of sufficient length to deliver the water against the force of the atmospheric pressure. In the discharge-pipes F are valves I1", which are attached to a common stem, F2, and by moving said stem longitudinally the valves are alternately opened and closed. rIlhe stem F2 is reciprocated by means of a bell-crank lever, G, receiving motion through a rod, Gr', from the beam or lever C, and it will be understood that when the steam-valve c ot' either chamber A is closed the water-valve F of that ch amberis open, and vice versa.

In order to provide for the escape from the chambers A ot' any air which may enter with the steam and water, I employ a novel form ot' valve, (shown in section as applied to the left-hand chamber.)

H designates a shell in the top of the chamber A, in which are tted a double puppetvalve, g, and a float, g'. Any air which may enter the chamber of course rises to the top thereof as the water rises therein, and when the water nearly reaches the top of the chamber is forced out through the valve y; but as soon as all the air is discharged and water, `A

passes through the valve g the float g is raised by the water and closes the valve tightly against its upper seat.

In the drawing I have represented the lefthand chamber A as performing the service ot a condenser, while the discharge-valve F of the right-hand chamber is open andthe water is being discharged therefrom. Steam and water en ter the left-hand chamber, and the water, gradually rising therein, elevatcs the float B, and, acting upon the beam C, tilts the same, shutting the cock or valve c ot' the left-hand chamber and opening the other cock or valve c, whereupon the operation is reversed and IOO the right-hand chamber is filled,while the full left-hand chamber is discharged.

By my invention I provide a simple and de sirable condenser which is continuons and au- 5 tomatic in its action, and with which n0 airpump is necessary.

What I claim as my invention, and desire to secure by Letters Patent, is*

1. In a condensing apparatus, the combinaa tion of two chambers, each having a steam and water inlet, and a Water-outlet communicating with a Torricellian column or barometric leg, valves arranged in said inlets and outlets, a weighted tripping beam or lever with which all said valves are connected, and floats within t5 said chambers for actuating said beam or lever, substantially as and for the purpose specified.

2. The combination of thechambersA A, the inlet pipe and valves E a, the injectionpipesf, the outlet pipes and valves F F', the 2o tripping beam or lever C, connected with all said valves, and the floats and rods B B', for acting upon said beam or lever, substantially as specified.
