SPECIFICATION forming part of Letters ratentno. 725,212, dated Apri1'14, 1:903. pp i filed April 1 2- Serial No. 104.805. (N0 model.)

To'otZZ whont it nuty concern:

Be it known that 1, WILLIAM 0. BROWN, a citizen of the United States,residingin the borough of Richmond, city of New York, county of Richmond, and State of New York, have invented certain new and useful Improvements in Condenser Systems, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The object of the present invention is to provide an improved condenser system of that class employing surface condensers, and especially to provide a construction for efliciently separating the air and other uncondensable vapors from the water and, delivering them from the system.

A further object of the invention is to provide an apparatus in which the water of condensation is efficiently removed from the surface condenser whatever be the variation in amount of water flowing from the condenser.

The following are the two broader features of the invention: the combination,with a surface condenser and air-pump, of an air-cooler arranged so that the air passes through the cooler on its way to the air-pump, and the air is thus cooled and any condensable vapors therein condensed, the cooler being preferably inserted with the circulating-head of the condenser, so as to be cooled by the circulating water, and the combination, with a surface condenser, of a centrifugal or turbine pump for removing the water of condensation, so that the delivery of the pump will vary with the amount of water passing from the condenser and even a very small flow from the condenser be taken care of by a pump running at a constant speed without any floatvalve or other special control or regulating apparatus.

The invention includes also various features of construction and combinations of parts in condenser systems, all as more fully described hereinafter and particularly pointed out in the claims.

In the accompanying drawings, in which all the features of the invention are shown as applied in a simple preferred form, Figure 1 is a side elevation of the condenser system. Fig. 2 is an end elevation of the same. Fig. 3 is a water of condensation.

Referring now particularly to the construction shown in Figs. 1 to 5, A is the condenser, which is shown as a horizontal condenser, having the inlet B at the top for the exhauststeam and the usual vertical tail-pipe 0, opening from the bottom of the condenser for the The condenser has the tubes D for the circulating or condensing water, which tubes open at opposite ends into the inlet-chamber E and outlet-chamber. F for the circulating or condensing water, with which, respectively, connect the inlet and out- The inlet-pipe E for the circulating water connects with the pump G, by

which the condensing water is forced through" the condenser, this pump being shown as a centrifugal or turbine pump operated by the motor H. The tail-pipe O, through which the water of condensation passes from the condenser, is shown as extending downward into the pit below the condenser, as usual in this class of apparatus, and is connected by pipe 0' to the centrifugal or turbine pump I,which is shown as actuated by the long shaft 10 from the motor K, placed on the same level as the motor H. that the means by which the pump I is actuated and its connections with the condenser are not important so long as the water of condensation is delivered by a centrifugal or turbine arranged so as to secure the results of the invention.

Referring now to the devices for removing the air from the condenser and cooling it, the air is collected from the condenser by a pipe L in the lower part of the condenser, provided with small openings 11, throughwhich the air enters, this pipe being shown in the form of a cross extending well over the bottom of the condenser, and the pipe L is connected by pipe M to the chamber N at the end of the condenser from which the air passes to the air cooler. This aircooler may consist of tubes running through the condenser-head from one side to the other; but preferably 1 It will be understood, however,

-to the hot-well or elsewhere.

use the construction shown, in which inner and outer pipes 12 13 in the circulating-water chamber E are arranged so that the air passes from chamberN through the tubes 12 and then returns through tubes 18 into chamber O at the same side of the condenser as chamber N, with which chamber 0 connects the air-pipe P, forming the suction-pipe of the air-pump Q, which is shown as a common crank-driven plunger-pump. The chamber 0 and pipes 12 13 form not only an air-cooler and supplementary condenser, but also a separator for separating any condensed liquid from the air, any such liquid passing into the bottom of chamber 0 and through pipe 25 If desired, of course, a liquid-separator distinct from the cooler may be put on; but the construction shown is efficient.

The construction shown in Fig. 6 is or may be substantially the same as that above described, except that the pipe L for collecting the air from the bottom of the condenser is provided with openings 14 on its upper side, and this pipe is covered by a hood 15, which prevents the water passing into the pipe from above as it condenses in the upper part of the condenser. The form of the bottom of the condenser is such that the condensing Water flows from the condenser into the tail-pipe without permitting the collection of water in the condenser to a depth above the pipe 14, so that the air-pipe is kept clear from condensed water, except as water-vapor may pass through the air-pipe with the air.

The cooling of the air and the condensation of any condensable vapors therein on their way from the condenser to the air-pump secure a much more efficient action of the condenser system and of the air-pump. The removal of the water of condensation by the centrifugal pump or turbine secures the efficient delivery of varying amounts of water by a pump run at a constant speed and retains even the smallest amount of water, so as to keep the condenser clear, and this is impor tant also in securing an efficient and economical operation of the system.

While the air-cooler is preferably placed Within the condenser or condenser-head, so as to be cooled by the incoming condensing water, it will be understood that the air-cooler may be otherwise arranged and cooled and that the invention is not to be limited to the special form of apparatus shown as embodying the invention, as this may be varied widely While retaining the features claimed.
