Specification of Letters Patent.

Application filed March '7, 1906. Serial No. 3%,628.

To all whom it may concern:

Be it known that. I, GUSTAV B. Persona, a subject of the Emperor of Germany, residing in the city and. county of Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Condensers, of which the following is a true and exact description, reference being had to the accompanying drawings, which't'orm a part thereof.

My invention relates 'to condensers of the general character'of the condenser described in the patentto Weiss, reissue 11,591 or March 2nd, 1897, in which condenser the steam is condensed generally by a counter current mode of operation, but sometimes by a parallel current mode of operation, means belng provided for interrupting the vacuum when the condenser works by parallel currents and thus restoring it to normal counter current operation.

proved condenser.

The object of my invention is chiefly-to provide improved means for interrupting the vacuum and restoring the normal counter current operation in the apparatus, but I also have in view the general improvement of condensers of this kind.

The nature of my improvements will be best understood as described in connection with the drawings in which they are illus trated, in which- Figure 1 is a side elevation of my im Fig. 2, a sectional elevation on the line 22 of Fig. 1. Fig. 3, a plan view of the-head of the separation chamber with the top of the air-chamber removed. Fig. d is a crosssectional view through the air chamber taken as on the line H of Fig. 3, showing the lid of the air chamber in place. iii his a perspective view of the perforated imcket, and Fig. 6 is a perspective vien of the air valve and the parts of the valve operating mechanism directly connected therewith. 1

A is the bod otthe condenser, B the steam inlet leading into the bottom thereof, 0 the inlet leadingiu'to the top thereof, D tin-opening for convenient access to the lower part of the condenser body, E, E the water baron'ieter wastc pipe connecting with the bottom of the condenser and opening at bottom into a box E having openings as indicated at l) at each end, saidppenings being provided with l'iinged gates or valves 12*. The construction of the box. and its valves is the same as that of the box marked 11*, shown in Fig. 2, and hereinafter described. The box is situated in the waste water well I which in my improved'construction is a closed Well provldediwith a take oil pipe F and a cover F through which the water barometer pipes pass.

From the top of the condenser body leads the conduit G, ail-extension G of which is prolonged into the separation chamber H, as shown in .Fig. 2. An air pipe I, leads Patented Feb. l, 1910.,

from the top of this separation chamber to an air pump I. The separation chamber H connects at bottom with a water barometer waste pipe H, which extends down into the waste water well connecting at bottom with a box H having openings H provided with hinged valves Hf. I

To an elbow G? onthe pipe G I attach the air chamber'J, provided with an air port J, and supporting pivots'at J 2 and J.

K is the air. valve, normally heldseatedon the air port by some yieldingor resilient force, as by 'being supported on the cross bar K of the levers K K? pivoted at J,

and provided with a counterweight K.' The valve has also attached to it the rod L, which is connected with the end of the lever L pivoted in the air box at .J, and connected atan intermediate point with the dependlng rod U, which extends into the separation chamber, where itis attached to a perfo-- rated bucket M, iv indicating the perforation in the bottom of the bucket, and M? guide plates secured to the walls of the sepa ration chamber and serving to steady the perforated bucket. A pipe J connects with the air box J and leads into the head of the condenser chamber, as shown in Fig. 2. v

To return to the detailed construction of the condenser chamber, it will be. seen that the water'inlet 0 leads into an annular water chamber A in the top of the condenser, an annular rim A being provided at the top of the chamber and formed to direct the overflow of the water inwardly toward the center of the chamber, where it flows against a conical battle plate A, provided with perforations, through which a ortion otthe water is directed inward, whi e another portion tldwing over the bafiie plate is directed outward, as shown, and flows down until it comes-in contact with the annular conical flange or battle plate A also provided with perforations through which a portion of the water flows downward while the remainder of the water is directed inwardly tothe perforated dish-like battle plate indicated at A A tubular extension A5 extends up from the dish A, and a tubular extension A extends upward from the top of the conical baffle plate A, and at the bottom or" the condenser chamber I provide the upwardly converging flange A to insure that the water shall fall into the upper end of the waste pipe E out of contact with the sides of the pipe.

By inclosing the waste water well F, I avoid objectionable features of similar condensers owing to the splashing of water and. occasional ebullitions of steam, and by placing the device which covers the mechanism for breaking the vacuum in the separation chamber I also avoid the splashing of water mally in such volume that whatever portion is caught in the pail M runs freely out of the perforation Mf. Where the water is heated in the condenser body to a point where it willdpass upward with the air and steam in stea of downward, it rushes into the separation chamber H, in such volume as to fill the perforated pail M, the weight of which when filled with water is sutlicient to overcome the counterbalance K and draw the air valve K downward, permitting air to enter the air box through the port J, whence it passes into the ipe G and also through the pipe J into t e head of the condenser body, breaking the vacuum in the condenser to such a point that the water will no longer pass upward with the steam and thus restoring the condenser to normal counter current operation.

The'bafi le plate system of the condenser body has already been sutliciently described and is clearly indicated by the lines indicating the How of water in the drawing, Fig. 2. Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a condenser of the character described adapted to operate either as a parallel current or counter current condenser, the combination with the condensing chamber and the conduit through which the water passes from the condensing chamber when the condenser is working as a parallel current condenser, of means for temporarily ceases breaking the vacuum in the condenser, and an actuating device for said means comprising a perforated pail situated in said con-- dint. above the level to which water accumulates therein, and normally held in a fixed non-operative position by a yielding force, said pail being arranged. to be urged in the same direction out of said non-(normative po sition by the direct. impact against the pail of the water passing through said conduit and by the weight oi the water accumulating in said pail.

In a condenser having a body connecting at bottom with a waste water barometer pipe and at top with both an air pump and a waste water barometer pipe through a separating chamber, and having means for temporarily interrupting the vacuum in the condensing body, a device for operating said means to break the vacuum consisting of a perforated pail situated in the separator chamber and normally held in fixed nouoperative position by a. yielding force said. pail being arranged so that it; is urged in the same direction away from said non-operative position by the direct impact; of the water passing through the eparator clnnnlzcr and by the accumulation of water in the pail.

3. In a condenser of the character dcscribed having waste water barometer pipes connected with both the bottom and top of the condenser body, av closed waste water well into which both of said barometer pi pcs open, means for temporarily breaking the vacuum in the condenser, and a device for actuatin said means comprising a periorated pail situated in a conduit leading from the top of the condenser to the barometer pipe connected therewith and adapted to be actuated when there is an excessive flow of water through said conduit by the direct impact of water flowing through said conduit and by the weight oi the water accumulating in said pail.

4. In a condenser of the character dcscribed having waste water barometer pipes connected with both the bottom and top of the condenser body, the latter connection being through a separator chamber connected also to a vacuum pump, a closed waste water well into which both of said barometer pipes open, means for temporarily breaking the vacuum in. the condenser and a device for actuating said means consisting of a perforated pail suspended and guided for vertical movement in the separator but normally held in a fixed non-operative position by a yielding force, said pail being urged downward by the direct, impact. of water passing through said separator and also by the weight of water accumulating in said pail when an excessive flow of water through the separator takes place.
