Patented Apr. 5, il'tik Application filed June 10, 1308 Serial No. 437,716.

To all whom it may concern:

Be it known that I, Jnrrin W. Hairpin, a citizen of the United States, and a resident of Sourlake, in the county of Hardin and State of Texas, have made certain new and useful Improvements in ater-Heaters, of which the following is a specification.

My invention relates to improvements in feed water heaters and has for its object to provide an improved apparatus for the rapid and economical heating of water for steam purposes in oil and gas burning boilers.

My invention consists in certain novel tca tures of construction, arrangement and combination of parts as will be hereinafter fully described and pointed out in the claims, reference being had to the accompanying drawings, in which Figure 1. is a perspective view of a boiler turnace showing location of my improvement. Fig. 2 is a rear View of the tar et Fig. 3 a section taken on line S-3 ot Fig. Fig. 4 is a section taken on line d4; of

In carrying out my invention I use a plate A of cast iron, which may be square or oblong and may be from one-halt to one inch in thickness, this plate being termed the target This plate is set up inside the boiler turnacc in place of the tire brick target used in oil burning boilers. To the back of the target is secured the pocket 1%, which, as shown, is enlarged at its central portion 3* and narrows down toward its ends where the connections for the feed water pipe are made. The incoming teed water enters the pocket B at end B and after passing diagonally across the target, that being the position of the pocket, discharges at the end B that is, the water from the teed pipe on its way to the boiler teed connections will pass immediately back of the target plate and through the pocket, passing directly opposite and back of the point where the jet of burning fuel oil is thrown against the plate. The pocket B will be appr Ximately three times the capacity of the same length of straight teed pipe, thus permitting the water to pass slowly by the point where the fire is hottest, thus becoming already heated before it reaches the boiler teed connections. The base of the target plate is made with. a flange B extending rearwardly and bent at such an angle that the target plate stands at an angle of about by thus inclining the target plate backward the heat thrown against the target plate from the oil jet is deflected upward and toward the boiler dues, and thus avoiding waste of heat. in the event it is desired to use more than one boiler, or, what is known as a battery of boilers, these plates or targets may be connectcd by the teed pipe, and, the water instead of passing from the first target or heating pointinto the first boiler, will pass through the heat. of all the boilers in the battery. and is fed back hot into the other boilers by means of ordinary teed lines or feed columns, thus greatly reducing the amount of i'uel oil or gas required tor producing the necessary amount of steam. These targets may be made in any desired size, for use in connection with the various sizes and kinds of boilers used.

The front of the target. will be protected by a facing of the brick or other heat resisting medium, held thereon in any suitable manner. The target plate may be made in sections which can be readily passed through the furnace door, and then assembled and held together in a. single plate by tongues and'grooyes, or other suitable means. The target itself may constitute the circulating medium for the feed water, it only being necessary that such medium shall be interposed in the path ot the injected flame. The flange B may also be dispensed with as the feed water pipe connections will form a suitiiciently strong support to maintain the target in its desired position. By inclining the target the full force of the flame is not allowed to get to the boiling lines as such would soon burn them out.

i: claim l. A device for heating feed water in oil or gas burning boiler furnaces, consisting of a target plate mounted within the lire box and inclined upwardly and rearwa-rdly in the tire box, a pocket located at the rear of said plate, said pocket having connection at one end with feed supply, and at the other end with the boiler teed connections.

2. A device for heating teed water in oil or gas burnin boiler furnaces, consisting of target plate having a bent base to cause the plate to setat an angle and project upwardly and rcarwardly in the fire box, a

pocket located at the back of the plate to serve as a passage for feed water, said pocket being enlarged in its central portion, and having connection at one end with the feet water supply and at the other with the boiler feed connections.

3. A device for heating feed water in oil or gas burning boiler furnaces, consisting oi? a target plate having a flanged base disposed atan angle to cause the plate to suine a rearwardly inclined position, a pocket located at the back of the plate and extending diagonally across the same, said pocket serving as a passage for feed water and having a connection at one end with the feed water supply and at its other end with the boiler teed connections.

t. A device for heating feed water in oil or gas burning boiler furnaces, consisting ot a metal plate having anangularly disposed base flange, a pocket placed at the back of said plate extending diagonally across the same, and having its central Zone enlarged, said pocket serving as apassage for the teed water, and having connection at one end with the feed water supply, and at its other end with the boiler teed connections.

5. A device for heating teed water in oil or gas burning furnaces, consisting of a feed water conducting medium located within the fire box and tilted rearwardly at an angle from the vertical, and positioned to receive and defiect upwardly and rearwardly the flame of an injector burner.

(3. A device for heating feed water in oil or gas burning furnaces, consisting of a target plate constituting feed water medium, tilted rearwardly at an angle from the Vertical, and positioned in the fire box of the furnace to intercept and deflect upwardly and rearwardly the flame of an injector burner.

T. A device for heating feed water in oil or gas burning furnaces consisting of a target plate placed within the fire box of the furnace and inclined upwardly and rearwardly, a pocket forming part of said plate and having connection at one end with the feed water supply and at the other end with the boiler teed connection, said feed water and boiler feed connections supporting and holding the target plate in position within the fire box.

8. A device of the class described comprising an oil discharge nozzle, a targetin the path thereof and constituting a feed water heater, and means for directing water to and from the target.
