COMBINED FEED-PUMP AND CONDENSING APPARATUS.

SPECIF'TCATIN forming p art of Letters Patent 110.307,04?, dated October 21,1884.

Application filed July 2, 1934. (Xo model.)

lo all w'wm, it may concern:

Be it known that I, JOHN HOUPT, of Springtown,in the county of Bucks and State of Pennsylvania, have invented a new and Improved Combined Feed-Pump and Condensing Apparatus, of which the following is a full, clear, and exact description.

rlhis invention more particularly relates to combined feed-pumps for steam-boilers of marine engines and condensing apparatus for supplying hot fresh water thereto, substantially as described in Letters Patent No. 296, 009, granted to me April 1, 1884; and it mainly consists in a loaded or safety-valve and whistle or alarm attachment to said devices, for the purpose of indicating the internal pressure and working condition of the auxiliary force or feed pump forming partof the apparatus.

The condensing and boiler-feeding apparatus for steam-engines described in my abovenamed Letters Patent used a primary and a secondary condenser, and included a combination, with the primary condenser or moderator for direct application to or connection with the engine-cylinder, and arranged .intermediately of said cylinder and the secondary condenser, and with a feed or force pump in controllable connection with the duct which passed oif the hot water of condensation from the primary condenser, of apipe or duct in controllable connection with said :force or feed pump, and with the secondary condenser for drawing off accumulated vapor from the pump; and said apparatus, furthermore,included a combination,with the primary condenser or moderator and secondary condenser of such compound condensing` apparatus, of a compound plunger, force, or feed pump adapted to supply to the boiler of an engine hot fresh water of condensation from the primary condenser. The invention which is the subject of this specication combines with theauxiliary forcepump andsecondary condenser a chamber, in combination with said forcepump,iitted with 'a loaded or safety valve and alarm or whistle,

and escape-pipes for hot water and vapor collecting in said chamber, substantially as hereinafter specified, and for the purposes hereinbefore named.

Reference is to be had to the accompanying drawing, forming part of this speciiieation, iirwhich the gure represents a vertical sec- -tion of a combined feed-pump and condensing apparatus with safety-valve and steam-whistle attached, all in accordance with my invention.

A indicates the cylinder of the feed-pump proper, and B its plunger, C, the deli-veryvalve of the pump, arranged at the upper or discharge end of the cylinder A under cover of an outlet-branch, I),'connecting with the boiler.

E E EL indicate the hot-water-supply pipe to the upper or discharge end of the cylinder A from the cylinder F of the auxiliary force or feed pump, the plunger of which is indicated by the letter J. n

G is a gage-cock titted to said pipe, and H a spring check-valve arranged within a chainber, I, between said pumps.

L indicates the inlet-valve of the auxiliary pump, and K M N O P are the pipe-connections between the hot-water feed-pump and the condensing apparatus.

R is the primary surface-condenser; S, the secondary surface-condenser or save-all; T, the air-pump; U, the upper hot-well, and Y the hot-water-boiler supply-pipe. rlhe pipe N, which is controlled by a cock, G', serves, in conjunction with the pipe O, to connect the pump F with the upper end of the secondary condenser S or pipe r leading thereto. The pipe O is an elevating one and inclines upwardly from the pump-cylinder F to draw oft' -the hot pure vapor from the compound plunger-pump by the air-pump T of the condensing apparatus, and thereby utilizing said vapor,ins`tead of allowing it to become an annoyance,in equalizing and overcoming back-pressure on the receiving-valves of the pure hotwatcr feed-pump. rlhe primary condenser R R,which first receives the exhaust-steam by an inlet, g, has the hot water of condensation passed oft' from it by the pipes r 1" into the lower hot-well, XV, for transmission to the boiler, and M is the pipe controlled by a cock, G2, and connected with the pipe r', through which the hot fresh water at a higher -temperature than could be aiforded by the ordinary condenser is drawn by the compound forcepump and forced into the boiler.

Z indicates the circulating-pump of the condenser.

Q is a safety-valve and whistle or alarm chamber in communication below by a pas- IOO ber.

sage,b,\\'itl1 the space or chamber immediately above the plunger J of the auxiliary forcepump. Said chamber Q is also connected below by a pipe, X, with the pipe M for escape of any accumulated hot water, and is counected above by a pipe, Y, with the elevatingpipc O for escape of hot vapor l'rom said cham A is a safety-valve within the chamber Q, and B/ a vapor or steam Whistle therein. These devices, which, by means ol'l Jthe pipes X Y, are connected with the secondary condenser, serve toindieate the internal pressure and working condition of the auxiliary force or feed pump, the valve A rising and the Whistle or alarm B being sounded whenever the pressure is excessive.

Having thus described my invention, l claim as newand desire to secure by Letters Patentl. In a combined feedpump 'for boilers and condensing apparat-us, the combination, with the pump and condensing apparatus, ol" a chamber in communication with both, and a safety-valve and Whistle or alarm arranged within said chamber, substantially as and for the purposes speciiied.

2. The combination, with the auxiliary boiler force and feed pump F J,lhe secondary condenser S, and the hotwvater and vapor pipes M @,connccting said pump and condenser, of the chamber Q, the duct 7), connecting said chamber with the pump, the hot-Water-escape pipe X, and hot-vapor-escape pipe Y from said chamber, and the safety-valve A, and alarm or Whistle B', arranged within said chainber, essentially as described.

3. In condensing and boiler-feeding apparatus i'or steam-engines in which a primary and secondary condenser are used, and in which a compound plunger force or feedvpump for supplying the boiler with pure het Water is combined with the condensing apparatus, the combinatiomwith the pump-cylinders AF and their valves and connections,and with the primary condenser ,lt and secondary condenser S, ol" the air-pump T, the hot-Wells U Q the pipes r r 9",the hot-water pipes P M,the hotvapor1 pipe O, the pipes or ducts X Y I), the valve-chamber Q, the loaded or safety valve A', and the Whistle or alarm BQ substantially as shown and described.
