FEED-*WATER HEATER;

SPECIFICATION forming part Of Letters Patent N0. 724,413, dated. ll/Iar'cli 31, 1903. Application filed December 20, 1902. Serial No. 135,987. (No model.)

To all whom it may concern:

Be it known that LFRANK C.TRAUER, a citizen of the United States, residing at Heizer,'

in the county of Barton and State of Kansas, have invented new and useful Improvements in Feed-Water Heaters,- of which the follow- .ing is a specification.

My invention relates to improvements in feedwater heaters for steam-boilers, and more particularly pertains to that class used on locomotives.

The object of my invention is to provide a device of the character described in which the waste heat and smoke passing through the smoke-box and the smoke-stack is more efiectively used in heating the water before it is fed into the boiler and saving fuel and also allowing a greater steam-pressure to be kept in the boiler with the least possible amount of fuel.

Another object of my invention is to provide a device of the character described which is provided with means for cleaning the same and also means for drawing the water therefrom for the purpose of preventing the same from freezing when the engine is not in use.

In the accompanying drawings, Figure 1 is a perspective view of a locomotive with my device attached thereto. Fig. 2 is a transverse sectional view. Fig. 3 is a front view of a locomotive. Fig. 4 is a detached perspective view of the tank, showing the opening through which the smoke-stack passes.

Referring now to the drawings, A represents the ordinary tubular boiler used on 10- comotives now in use, and B is the smokebox carried by the forward end thereof and through which passes all of the smoke and gases from the fire-pot or furnace. Extending in the usual manner from the upper portion of said smoke-box is the smoke-stack C, which conveys the smoke and gases upward and causes a greater draft within the grate or fire-box.

The receptacle or tankD is oblong and extends transverse the smoke-box, and the upper portion is provided with an enlarged opening (I, through which the smoke-stackO passes, and surrounding the same is an upwardly extending flange d, by means of which it can be secured to the smoke-stack by rivets or bolts. The bottom of the tank D is formed by theupper portion of the smoke-box B, and surrounding the entire lower edge of said tank D is a flange d. Passinglthrough said flange and the smoke-box are bolts or rivets, by means of which the tank is held thereon and by means of which a water-tight connection is formed. By this construction it will be seen that the bottom of the tank is formed by the upper portion.

The ends of said receptacle or tank D, adjacent the lower portion, are provided with stopcocks F and F, of any desired construction, which will allow the water therein to be drawn off for the purpose of preventing it from freezing when the engine is not being used. The forward side-of said receptacle or tank D is provided with openings G and G, adjacent the ends, through which sediment may be readily removed. Surrounding said openings are outwardly-extending bolts H, which pass through the plates I and I,which cover said openings, and between said plates and the tank are packings, and screwed upon the ends of the bolts H are nuts H, which are adapted to force the plates I and I upward, and thus, make a water-tight connection. The upper portion of the receptacle or tank D is provided with an opening J ,through which the water is injected to fill the tank and boiler when it has been drawn ofi for the purpose of preventing the freezing thereof, as the water cannot be forced through the pipe E before the steam has been generated in the boiler, as the means carried by the pipe E for forcing water into the tank is driven by the engine. Connected to the upper portion of the opposite end to which the supply-pipe is attached is a pipe K, which extends downward and runs along the boiler and enters the same about midway its length, so that the heated water will enter the con ter of the boiler and evenly distribute itself V smoke-stack carried by said box, of a feedwater heater comprising an elongated tank extending transverse the boiler and having a central opening therein adapted to receive the smoke-stack, a flange surrounding said opening and secured to the smoke-stack, and a flange surrounding the lower edge of said tank and secured to the said smoke-box.

2. The combination with a cylindrical boiler having at one end a smoke-box, an upwardly-extending smoke-stack carried thereby, of a feed-water heater comprising a rectangular tank having, a curved open bottom adapted to rest upon said smoke-box, a flange surrounding said open bottom and secured to the smoke-box, the said tank having an opening in its top adapted to .receive the smoke-stack, and a flange surrounding said opening and secured to the smoke-stack.

3. The combination with a boiler having at one end a smoke-box and an upwardly-extending smoke-stack, of a feed-water heater comprising an elongated tank, extending transverse the boiler and supported thereby and surrounding the smoke-stack, a supplypipe in communication with the lower portion of one end of said tank, a discharge-pipe in communication with the upper portion of the opposite end and connected to the boiler, a check-valve carried by the pipe intermediate the boiler and tank, said tank having cleanout openings carried by the forward side, and cooks carried by the lower portion of each end, substantially as described.

4. The combination with a boiler having at one end a smoke-box and an upwardly-extending smoke-stack, of a feed-water heater comprising an elongated tank extending transverse the boiler and supported thereby and surrounding the smoke-stack, a supplypipe in communication with the lower portion of one end of said tank, a discharge-pipe in communication with the upper portion of the opposite end and connected to the boiler, a check-valve carried by the discharge-pipe intermediate the tank and boiler, said tank having clean-out openings carried by the forward side, cocks carried by the lower portion of each end of said tank, and the upper portion of said tank having a filling-opening, substantially as described.

5. The combination with a boiler having at one end a smoke-box and an upwardly-extending smoke-stack, of a feed-water heater comprising an elongated tank extending transverse the smoke-box and having an open ing in its upper side through which the smokestack passes, a flange surrounding said opening and secured to said smoke-stack, and the bottom of said tank formed by the upper portion of the smoke-box, and a flange surrounding the lower portion of the tank and'bolted to the smoke-box, substantially as described.

6. The combination with a boiler having at one end a smoke-box and an upwardly-extending smoke-stack, of a feed-water heater comprising an elongated tank extending transverse the boiler and resting upon the same and surrounding the smoke stack, flanges carried by said tank and secured to the boiler and smoke-stack, a supply-pipein communication with the lower portion of one end of said tank, a discharge-pipe in communication with the upper portion of the opposite end and connected to the boiler, a checkvalve carried by the pipe intermediate the boiler and the tank, said tank having cleanout openings carried by the forward side, and cooks carried by the lower portion of each end.

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

FRANK C. TRAUER.
