Specification of Letters Patent.

Application filed July 20, 1909. Serial No. 508,671.

To all 'whom it may concern.'

Be it known that I, EDWARD VIKI, a citizen of the Republic of Switzerland, residing in Lucerne, in the Canton of Lucerne, in the Republic of Switzerland, 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 form a part thereof.

My resent invention relates to steam condensers of the jet type, and the object of the invention is to so construct and arrange a condenser of this type, and its water circulation controlling provisions, that vthe condenser may be operated with such an equalizing water accumulator or reservoir in combination with the condenser proper as is described and claimed in the patent to NVeiss, No. 7 71,515, granted October lth, 19011, or

may be operated without the use of such an accumulator or reservoir.

In a condenser provided with an accumulator arranged and operating as described and claimed in the Weiss patent, the condensing water is caused to pass in series through two or more condensing ranges within the condensing chamber and a reservoir or reservoirs are provided, into each of which the water from one of a pair of condensing ranges is passed on its way to the other condensing range. By this arrangement the temperature of the water in the reservoir or tank between two condensing ranges corresponds to the average temperature at which the water leaves the range from which it passes to the reservoir. Hence when the steam supply to the condenser is intermittent, as it usually is, the water in the reservoir or reservoirs forms a for efficiently taking care of steam admitted to the condenser at any instant in excess of the average steam supply. The use of such accumulators or reservoirs has been found highly advantageous in practice as more steadily and efficiently with varying steam supplies than they would otherwise, and each condenser will take care of a larger temporary steam supply than could be taken care of at all by the same condenser without such a reservoir or reservoirs. Vhile the advantages of such accumulators or reservoirs are well recognized, conditions sometimes occur where it is desirable to operate an accumulator condenser for a period without using the accumulator reservoir or reservoirs. This may occur where the accumulators or reservoirs of a condenser require repairs and from other reasons it may become desirable to temporarily dispense with the use of the accumulator reservoir or reservoirs in an accumulator condenser which has been installed and operated with an accumulator reservoir in place and connected up. In other cases it is desirable to initially install a condenser, and put it in operation, without at the same time installing and connecting up an accumulator reservoir in order to save time or expense, or for other reasons, while, at the same time, the ability to readily provide such a condenser with an accumulator reservoir or reservoirs in the future is desirable.

By the use of the present invention, a condenser adapted to operate as an accumulator condenser when the proper reservoir and pipe connections are made, may be initially installed and operated without the provision of the accumulator reservoir or reservoirs and connections, and as an accumulator condenser which has been provided and used with an accumulator reservoir or reservoirs may be readily operated when desired without such reservoir or reservoirs. The various features of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of the invention however, and the advantages possessed by it, reference should be had to the accompanying drawings and descriptive matter in which I have illustrated forms in which the invention may be embodied.

Of the drawings, Figure 1, is an elevation, partly in section, showing an accumulator condenser and reservoir, with the condenser and its connections constructed and arranged in accordance with the present invention. Fig. 2, is a view, taken similarly to Fig. 1, showing a portion of a condenser substantially like that of Fig. 1 with a modified set of connections which may be used when the condenser is operated without an accumulator reservoir. Fig. .3, is a view, taken similarly to Fig. 2, and showing a portion of a condenser substantially similar to that of Figs. 1 and 2, having another arrangement of connections for use when the' condenser is operated without the accumulator reservoir, and Fig. 4 is a view taken similarly to Fig. l, showing the invention applied to a different type of condenser from that shown in Fig. l.

In the drawings, and referring first to the construction shown in Fig. l, A represents the body of a condenser of the lVeiss counter current type; B the main condensing water discharge conduit in the form of a barometric column; C the steam supply connection; D the cold water supply connection; E the connection leading from the upper end of the condensing chamber through which air and steam are normally discharged and through which water may issue from the condenser when the condenser operates as a parallel current condenser, as it does from time to time in practice; F represents cold condensing.'

a portion of the steam and air and water separator, and G the air pump connection; H represents an annular receptacle located in the condensing chamber into which the water passes from the pipe D.

I", I2 and I3 represent steam and water baffles by which the condensing water o-verflowing from the annular receptacle H is caused to pass in a broken stream through the upper condensing` range of the condenser into the annular receptacle J. Below the receptacle J is located another annular receptacle K. Below the upper end of the receptacle K is located a conical baflle I, and an annular baffle I5 which cause the water overflowing from either receptacle J or K to pass in broken streams through the second or lower condensing range of the condenser before it finally passes into, the body of water discharging through the conduit B. The condensing chamber is provided with a discharge orifice J 2 leading from the receptacle J and connected by a conduit L with the upper end of an equalizing or accumulating reservoir M. A pipe or conduit N leading from the lower end of the equalizer M is connected to an inlet orifice K2 in the condenser body leading to the receptacle K. Valves L and N are provided in the conduits L and N, respectively, and these conduits are connected between the condenser body and the valves by a bypass pipe O in which is placed a valve O.

In normal operation the valves L and N i are open and the valve O closed. In consequence the condensing water used in the first condensing range passes from the receptacle J into the upper end of the reservoir M. lVater passing from the lower end condense a portion of the of the reservoir M through conduit N 1s supplied to the receptacle K for use in the second condensing range of the condenser. Both the condensing ranges are effective to steam supply, the portions condensed by the two ranges varying to some extent with the arrangement in the condensing chamber of the receptacles and baffles and depending of course on the relation between the temperature of the water supplied to the upper condensing range through the pipe D and the temperature of the water supplied to the lower condensing range from the reservoir YM. At periods when the steam to be condensed is relatively small the water discharged into the reservoir M through conduit L is cooler of course than when the steam supply is larger. In consequence the water issuing from the reservoir M through the conduit is of a temperature which is an average of the temperatures of the water passing into the reservoir at different periods and with an intermittent steam supply the temperature o-f the water supplied to the second condens` ing range is always lower than the maximum final temperature of the water used in the upper' condensing range. In consequence the reservoir provides a supply of moderately heated water for taking care of the steam at periods when the supply of steam is much in excess of the average steam supply. Then for any reason it is desirable to operate the condenser without using the reservoir M, the valves L and N are closed Y and valve O is opened. When this is done the water will pass directly from the receptacle J into the receptacle K through the pipe O and the flow of the water through the two condensing ranges will be exactly the i.. same as before, but of course, since the accumulator reservoir is not used, the temperature of the water supplied to the second condensing range will vary from instant to instant with the final temperature of the water used in the first condensing range and hence the condenser will not operate as satisfactorily at periods when the steam supply is much above the normal. Then the steam supply is uniform however, the condenser will operate practically as eificiently as when the accumulator is connected in place.

4If the valve O is left closed when the valves L and N are closed the water accumulating in the receptacle J will splash over the inner edge thereof and, unless the consequent rise of the water level in the 115 receptacle J interferes with its operation, the condenser will operate practically as it did with the valve O open, though in this case the upper level of the second condensing range is slightly higher than before and lator M is cut out, and with such condensers therefore the pipe O and valve O may be dispensed with.

In installing an accumulator condenser without an accumulator but with the possibility of readily adding the acculnulator in the future, the bypass conduit O and valve O, as well as the pipes L and N and valves L and N may be dispensed with and other suitable provisions made for closing the passages J2 and K2 until the latter are closed by the equalizing reservoir after the latter is installed. Such other provisions may include stops for the passages or orifices J2 and K2 such as the covers P and P applied as shown in Fig. 2, where no exterior communication between the receptacles J and K is necessary, and where such connection is necessary or desirable, may consist of the bent pipe Q, secured in place as shown in Fig. 3.

In the construction shown in Fig. 4 I have shown an arrangement similar to that shown in Fig. l, by which an accumulator reservoir may or may not be used at will in connection with a common type of jet condenser in which A represents the condensing chamber, B the steam supply pipe, D the cold water supply pipe, J a receptacle at the lower end ofthe upper condensing range, and R represents a pumping mechanism for removing air and water from the condensing chamber. The connections between the receptacles J and K shown are identical with those between the receptacles J and K in the construction shown in Fig. l, and what has been said-above with respect to the arrangement of the connections between receptacles J and K applies to the connections between receptacles J and K of Fig. 1I.

Having now described my invention, what I claim as new and desire to secure by Letters Fatent is,

l. An injection condenser, adapted for operation with or without an equalizing reservoir, having in combination a condensing chamber, steam and cold water supply pipes connected thereto, means for drawing air and water from said chamber and water circulation controlling provisions includino` baille and receptacle devices located in'sai chamber, passages through the wall of said chamber adapted to be closed by the equalizing reservoir when the latter is in use and other provisions for closing said passages when said reservoir is not in use, all so relatively arranged as to cause the water admitted by the cold water supply pipe to pass in series through two or more condensing ranges, either by passing through one range to the other through said reservoir when the latter is in use, or without so passing when said passages are closed by said other provisions.

2. An injection condenser, adapted for operation with or without an equalizing reservoir, having in combination a condensing chamber, steam and cold water supply pipes connected thereto, means for withdrawing air and water from said chamber, and water circulation controlling provisions including battle and receptacle devices located in said chamber and passages through the wall ot' said chamber adapted to be stopped, placed in direct communication or connected through an equalizing reservoir, the whole being so relatively arranged as to cause the water admitted by the cold water supply pipe to pass in series through two or more condensing ranges, whether said passages are stopped or are connected directly or through the equalizing reservoir.
