FEEB WATER H EATER.

"'PECIFIGATION forming part of Letters Patent No. 675,553, dated June 4, 1901. Application filed October 29,1900. Serial No. $1,700. (No model.)

To ctZZ whom, it may concern: a

Be it known that I, JOHN WV. CASEY, a citizen of the United States, residing at Sistersville, in the county of Tyler and State of \Vest Virginia, have invented certain new and useful Improvements in Feed-W'ater Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to feed water heaters which are located in the furnace of steam-boilers, and has for its objects the better circulation of the water through the heater, whether the feed-water is being fed to the boiler or cut off, to collecting the sediment after the water is heated on its way to the boiler, and also to provide means for feeding the water to the boiler direct should occasion require the cutting out of the heater.

Referring to the drawings accompanying this specification, Figure 1 is a side elevation of a locomotive-boiler, showing the pipe connections from the injector to the heater and to the boiler direct and from the heater to the mud-drum and boiler. Fig. 2 is a section through the furnace and heater, taken on line 1 2 of Fig. 1; and Fig. 8 is a similar view showing a modification of the arrangement of the heater in the furnace.

It will be understood that all the pipe connections, the injector, and the mud-druin are duplicated on the other side of the boiler and that the drawings make a sufficient showing to fully illustrate the invention.

In the drawings, A. is the boiler, and B the furnace, in which is located crosswise the heater 0.

The heater is a vessel of any form, but shown in this instance cylindrical, and is provided with heads D D. The heater is divided horizontally nearly its whole length by plates (Z (Z, each of which extends from the heads to near the center, where an opening 6 is formed. To each head below the plates (Z (Z is attached the feed-water pipes E E from the injectors. Also to each head above the plates is attached the discharge-pipes F F, leading to the mud-drum and boiler.

Attached to the feed-water pipes E E is the circulating-pipe ll, provided with the valves 7t 7t and leading down to the waterspace of the furnace or fire-box.

I is the injector, having the usual steam and water supply connecting pipes 2'11 and the discharge '11. This discharge leads into a T-coupling, from which the pipe E leads to the bottom of the healer. Also from the same coupling leads the pipe L direct to the boiler. The pipes E and L are provided with valves m and Z, respectively. The discharge-pipe F F from the heater leads into the mud-drum G, which is provided with the blow-off pipe g and valve g, the latter of which may be operated from the cab in any well-known manner. From the mud-drum leads the pipe F to the boiler. This pipe is provided with a valve f. The pipes F andL are connected to a T-coupling, which is outside the usual check -valve coupling to the boiler. (Not shown.)

The pipes leading to and from the heater, as shown in Fig. 1, pass through the fire-box to the heater, while in the modification shown in Fig. 3 an opening the size of the heater is made in each side of the firebox and through which the heater extends and is supported by the same. In other respects the heater and its connections are the same.

In operation the Valves f, h, and m are opened and valve l is closed. The injector is started, when the water will pass through the pipe E to the bottom of the heater under the plates d d to the center of the heater, when it passes through the opening 6 and back over the plates and out through the pipes F into the mud-dru in G, which is of sufficient size to cause a slow current of Water, thereby permitting the sediment in the now heated water to settle in the mud-drum, where it can be blown off at pleasure. The now purified Water passes through the pipe F to the boiler.

Should the injector be stopped for any reason, the circulating-pipe would prevent the water from being converted into steam, and thereby burning the heater, since as the water is heated it passes up through the feed pipe into the boiler, and at the same time the heater is supplied with water from the boiler through the circulating-pipe.

While the feed-water is passing into the heater water from the boiler through the circulating-pipe also passes in with it. Therefore there is circulation of the water in the boiler as long as the heater is not cut out.

Should the heater become defective from long use or other reasons, the same can be cut out by closing valves h, f, and m and opening valve Z. This would cause the feed-water from the injector to pass through the pipe L direct to the boiler.

What I claim is-- 1. In a feed-water heater, the combination of a furnace with a water-heater therein,which is provided with horizontal division-plates which leave an opening in the center of the heater, water-inlet pipes entering each head below said plates, and water-outlet pipes leading from each head above said plates, substantially as described.

2. In a feed-water heater, the combination of a furnace with a water-heater therein,which is provided with horizontal division-plates which leave an opening in the center of the heater, water-inlet pipes entering each head below said plates, water-outlet pipes leading from each head above said plates, and circulating-pipes connected to the water-inlet pipe and lower water-space of the boiler, substantially as described.

8. In a feed-water heater, the combination of a furnace with a water-heater therein, feedwater pipes leading to the same, dischargepipes leadingfrom the same, and a mud-drum through which the water passes before entering the boiler, and means for feeding the water direct to the boiler or through the muddrum, substantially as described.

4. In a feed-water heater, the combination of a furnace with a water-heater therein, feedwater pipes leading from the injector to the heater, discharge pipes leading from the heater to the boiler, discharge-pipes leading directly from injector to boiler, and valves in said pipes by which the water may be directed through the heater or direct to the boiler, sub stantially as described.

5. In a feed-water heater, the combination of a furnace with a water-heater therein provided with horizontal division-plates leading from the heads to near the middle of said heater, and outlet and inlet pipes respectively above and below said plates, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN w. CASEY".
