Application filed May 20. 1903. Serial No. 157,914.

To all w/tm'n, it may concern:

Be it known that I, TnouAs F. Monnrn, a citizen of the United States, and residing at l Jersey City, county of Hudson, and State o" New Jersey, have invented certain new and useful Improvements in. Steam-Boilers, oi" which the rollowing is a specification.

My invention relates to steam-boilers, and I while it has particular reference to steaniboilers of the water-tube type the invention i is not limited thereto. I

l l l l l l In the accompanying drawing I have shown several forms of boilers in. which my invention is embodied.

In Figure I, I have shown a front view, partlyin section, of a boilerof the general type v now known on the market the Babcock & Wilcox water-tube boiler. In Fig. II, I have shown a. rear view of the said boiler with the 1 Walls partly in section. In Fig. III, I have shown a longitudinal sectional View of the boiler of the type shown in Figs. I and II. Fig. IV is a side elevation of a boiler embodying my invention, the said boiler being i of the marine type; and Fig. V is an end clevation or detail view of the upper part of the boiler,'showing the mode of arranging the i feed-water heater and superheater in the boiler.

Referring particularly to F g. II, a represents the drums of the boiler, which drums are ordinarily placed at the highest point in E the boiler. The bricked-in portions 1. ol the boiler-serve to surround the iron-work and l tubes, is usual in stationary boilers. c is i the fire-box, to which access is obtained b r f the usual type of door (1," and at the rear of the lire-box is a bridge-wall a. Extending l longitudinally of the boiler and suitably supl ported therein are one or more sets of ini vlincd water-tubesf, connected by suitable j headers 9, shown in the present instance as serpentine headers, although the said head i crs may be oi any desired constructimi. T he I set of water-tubes communicate by a trunk i or series ol trunks h with the drum at one end I and by a trunk or set ol trunks i at the other i end in order to produce the desired andv nee 5 cssary circulation. At or above the bridgewail e is a ballleplate j, shown in the present 5 instance as inclined and apcrturcd for the F passage of the water-tubes f. Another balllc-plate Z: is or likewise may be provided, l i'ic same being preferably located between the second flame-bridge Z and the bridge 6.

for to locate the feed-water heater.

B thus locatin the baffle lates and fire and flame bridges the course ot the i'lanie,

gases, and products of combustion is as follows: From the fire-box the flame and prod nets of combustion pass upward in front of the first fla1ne-bridge e and the battle-plate j, passing over the upper edge of the baflieplate 7', thence downward among the tubes beneath the second bafiie-plate to the rear thereof, and thence upward, passing out of the boiler through the flue connection m. It will be observed that a space above the longitudinally extending group of Watertubes is left above the said tubes and in front of the second lame -'bridge. This space is lettered o in the drawing and is for the purposes of containing the superheater. By referring to Fig. III it will be noticed that this supcrheater consists or a series of tubes 0, united. by common headers herein shown as ser entine headers.

In Fig. I, I have shown a pipe connection 0", by which the steam may enter the su er- .heater, and pipe connections 0 ,,by whie it may iind'a means of exit therefrom.

By referring to Fig. III it will be observed that there is a space in the rear of the rear or second flame-bridge l, Within which. I prefeed-water heater consists of transverse tubes p, united by headers g in the same n1annor as in the case of the constituent parts of the super-heater. The tubes constituting the feed-water heater are provided with any desirable usclul form of pipe-fittings o o and the headers are preferably located within the wall oi the boiler, so that the [lame does not come in-mntact with the'points of junction of the headers and tubes Where the tubes are expanded into the headers. At the ends ofthe feed-water heater I preferably locate and arrange one or more doors 0 in such manner that upon removing the doors access may be obtained to the feed-water heater for the purpose of cleaning, repairs, and inspection.

Details of the connections of the superheater'aud feed-water heater or economizer are not given in Figs. I, II, and III, as in Fig. IV and V such comiections are fully shown, and conseqi'iently nave been omitted from Figs. I, It, and iii for the purpose of clearness.

Above the Wall 3 is a series of Water, tubes 5 communicating at their ends by a series 0 headers 6 and 7. flhese headers are preferably serpentine headers and are provided with trunks. The headers 6 deliver into a suitable header or -1nanifold 8, con nesting by plpe or pipes 9 wlth'a steam-and water drum' 10.

In the drawin I have shown a deflectorplate 11, located inside ol" the drum 1 0, opposite theorilice 9 of the pipe 9. This delloctor-plate is useful to dellect the steam and hot Water entering the drum throi'igh the pipe 9. The lower part of the drum 1O communicatesby a suitable trunk or trunks 12 with the header 7, whereby ellicient steam circulation is secured. The ballle-plute 4 extends upward from the llame bridge or wall 3, and another bullle-plate 13 extends down ward about halt-way front the lop ol the group of inclined watM-tubcs. A suitable perforated partition or balll.cplate l-at like wise is provided and extends on an incline from the top of the frame of the boiler to the top of the ballle-platc l3.

I have shown in Fig. IV by the arrows the course of the flame and procucts ol'- combustion. Preferably located in the rear of the inclined battle-plate is a slmcrh'eater consisting of headers 15, receiving the ends ol tubes 16. -These tubes 16 extend transverselyof the boiler, preferably at substantially right angles to the inclined water-tubes .5. Steam comes to the superheater from the drum by the pipe 17. Owing to the fact that there is a part1t1on 18 in the headertbe steam is un able to pass laterally through the header, but

is deflected to the tubes 16, crossing the boiler and return ng tllrough the other set ol. tubes to the other side of the lileadcr 1:), and them-e passes out through theLp'iipe "In". in the space below thetop oi the boihw-l'rame and 1n front of the l altlc-platc i. harcshown a feed-water heater consisting cl, a plurality o l headers 19, connected. by pipes 20, tshowu in dotted lines hi Fig. V,l extending transversely claim, and desire to secure by Letters .latent,
