WATER HEATING AND FEEDING APPARATUS FOR STEAM-BOILERS.

SPECIFICATION forming part of Letters Patent No. 513,955, dated January 30, 1894.

, Applicationfiled October 11,1893. Serial No. 487.822. (No model.)

To all whom it may concern.-

Be it known that I, WINFIELD S. RICHARD- SON, a citizen of the United States, residing at Camden, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Water Heating and Feeding Apparatus for Steam-Boilers, of which the following is a specification.

My invention has relation to water heaters and feeders for steam boilers; and it relates more particularly to the general construction and arrangement of such apparatus.

The principal objects of my invention are first, to provide a comparatively simple, durable and effective water heater and feeder for steam boilers so constructed and arranged as to present the water to the boiler at all times at or about the boiling point thereof; second, to provide a water heater and feeder for steam boilers arranged so as to occupy a position above the water line of the boiler and with suitable steam connections arranged between the heater and feeder and the boiler and respectively connected therewith above said water line in the boiler; third, to provide a Water heating and feeding apparatus for steam boilers so arranged as to occupy a position above the water line in the boiler and with a steam pipe connection with the boiler above the water line in the boiler and with the bottom of the heater and feeder having a controlled feed connection to the boiler be low the water line therein; fourth, to provide a water heater and feeder for steam boilers heated through radiation by exhaust steam from an engine and with an overflow pipe or vent connection extending from the top of the heater and feeder to a waste receptacle; fifth, to provide a water'heating and feeding apparatus for steam boilers having pipe connections extending into the bottom of the apparatus from an elevated tank or reservoir for supplying the same with water and with an overflow pipe or Vent extending downward from the top of the heater and feeder and the water heated by exhaust steam from an engine, as wellas the water supply of the tank or reservoir and the heater and feeder disposed above the normal water line in the boiler with the water feed connection from the heater and feeder to the boiler arranged below the water line therein and the steam supply from the boiler to the heater and feeder to equalize back pressure thereon disposed above the normal water line of the boiler and connected with the top of the heater and feeder; and sixth, to provide a water heater and feeder for steam boilers adapted to feed the latter with an expansive fluid or water at or about the boiling point and with back pressure equalized or positively compensated for by a pipe connection disposed between the boiler and the heater and feeder and a pipe connection for permitting of the flow of the expansive fluid or water to the boiler from the heater and feeder by gravity, the construction and arrangement being such asthat all tendency to explosion or blowing out of the head of the boiler is avoided; and moreover, with the instantaneous conversion of the expansive fluid or hot water into steam upon admission to the boiler prevented, which is the constant tendency when water or an expansive fluid of an uncertain temperature is presented to a boiler in the now practiced modes of feeding the same, when the boiler is overheated.

My invention consists of the improvements in water heating and feeding apparatus for steam boilers constructed and arranged for operation in substantially the mannerhereinafter more particularly described and claimed.

The nature and general characteristic features of my invention will be more fully understood from the following description taken in connection with the accompanying drawing forming part hereof, and which illustrates partly in central section and partly in elevation a water heating and feeding apparatus in application to a steam boiler and in connection with an elevated water supply containing or embodying the features of my invention.

Referring to the drawings, A, is a steam boiler with its accessories of any preferred construction and arrangement for use.

B, is an elevated Water tank or reservoir provided with a supply pipe b, and with a discharge pipe I)".

C, is a water heater and boiler feeder provided with a pipe 0, extending through the same or formed into a coil the dotted lines therein. This pipe 0, extends from the engine D, and constitutes the eX- haust pipe thereof and it may be extended from the heater and feeder G, into the elevated water tank or reservoir B, in order to remove the chill of the water anterior to the discharge of the same from the tank or reservoir B, through the pipe b, to the heater and feeder C, and which pipe b, is connected with the bottom of the heater and feeder O. The pipe b, is provided with a stop-cock 12 as illustrated, for cutting off the supply from the tank or reservoir B, to the heater and feeder O.

0 is an overflow pipe or vent connected with the head of the heater and feeder O, and extending downward into a waste receptacle 0 This pipe 0 is provided with a stopcock 0.

e, is a pipe extending from the bottom of the heater and feeder G, into the wall of the boiler A, and it is provided with a stop-cock e, and with a check valve 6 to prevent back pressure.

f, is a steam pipe connected with the top of the heater and feeder O, and with the boiler A, above the normal water line thereof, for equalizing back pressure on the feed pipe 6, to the boiler. This pipe f, is provided with a stop-cock f.

The heater and feeder 0, located above the waterline of the boiler and the feed therefrom is arranged so that the water is fed or flows to the boiler by gravity and with the pipe f for equalizing back pressure on the feed the boiler can be always kept supplied with its required quota of hot water or expansive fluid; and moreover, as this fluid presented to the boiler is always at or about the boiling point, any danger or tendency to explosion or blowing out of the head of the boiler will be entirely obviated, and an efficient working'of the boiler will thus be insured with the requirement of the least possible attention being given thereto.

The operation of the apparatus hereinbefore described is as folloWs:To fill the heater and feeder O with water from the tank or resc, as indicated by ervoir B, the stop-cock b provided in the pipe 2), is opened, as well as the stop-cock c, in the overflow pipe or vent c and the respective stop-cocks e and f, in the feed and steam pipes e andf, are closed.

In feeding the boiler from the heater and feeder C, it will be understood that the respective stop-cocks b and 0 in the pipes 11 and 0 will be closed and the stop-cocks e and f, will be opened, thereby permitting nnder perfect regulation the boiler A, to be fed with hot water and the same may be readily and expeditiously kept supplied therewith with the least possible labor attending upon the same.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A hot water heater and feederfor steam boilers disposed above the water line of the boiler and provided with a controlled feed from the bottom of the heater and feeder and to the boiler below the water line therein, a steam pipe connected with the top of said heater and feeder and the boiler above the Water line therein, a controlled overflow or vent leading from the head of the heater or feeder and a water supply connected with the bottom of said heater or feeder, substantially as and for the purposes set forth.

2. A hot water heater or feeder connected with the exhaust of an engine and disposed above the water line of a boiler, a controlled water supply connected with the bottom of the heater and feeder, a controlled overflow extending downward from the top thereof, a controlled feed with a check leading from said heater and feeder to the boiler below the water line therein and a steam pipe connected with the top of the boiler and above the water line therein, substantially as and for the purposes set forth.

In testimony whereof I have hereunto set my signature in the presence of two subscribing witnesses.
