RUDOLPH D. KASSING, OF ST. LOUIS, MISSOURI.

STEAM-BOILER.

SPECIFICATION forming part of Letters Patent No. 450,940, dated April 21, 1891.

Application filed November 22, 1890. Serial No. 372,324. (No model.)

To ttZZ whom it may concern} Be it known that I, RUDOLPH D. KASSING, of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Steam-Boilers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in steam-boilers; and it consists in the novel arrangement and combination of parts, as will be more fully hereinafter described, and designated in the claims.

In the drawings, Figure 1 is a side elevation of my complete invention with a portion broken awayto more fully show the construction thereof. Fig. 2 is a longitudinal section taken on the line a: a: of Fig. 1, showing the arrangement of the deflecting-walls. Fig. 3 is a vertical cross-section taken on the line 3 y of Fig. 2.

The object of my invention is to increase the heating-surface and water-space of steamboilers without materially increasing the volume of the same. To achieve this construction I attach a water rib or basin to the shell of a boiler in a suspended position.

Referring to the drawings, 1 represents a boiler with a shell 2 and a series of longitudinal tubes 3 and a smoke-stack 4.

5 indicates the breeching of the front end of the boiler, having formed therein a manhole 6, through which the interior of the boiler can be inspected, and all precipitated products removed therefrom.

7 represents the furnace-chamber or the place in which the heat is generated.

8 indicates a series of grate-bars on which the coal or fuel is placed, and 9 are door-spaces through which the same is inserted and placed in the furnace-chamber, and 10 are doors which are adapted to inclose said spaces.

11 indicate the side walls of the foundation for the boiler.

12 indicates the water rib or basin, which embodies my invention. Said water-rib is suspended directly below boiler 1, and is thereto attached in any suitable and mechanical manner, preferably, however, by flanging the upper surface of said water-rib and riveting it to the exterior of the boiler by a series of rivets 11, as shown in the drawings.

16 represents the cap of said I water-rib, which is lapped over the end of the water-rib and thereto secured by means of rivets 17. The upper edge of said cap is flanged outwardly, however, and is secured to the exterior surface of the boiler in any substantial and mechanical manner. The inclosed space of said water-rib is in communication with the inclosed space of the boiler 1, which communication is elfected by means of elongated slot-s or perforations 18, through which the water contained in the boiler finds an exit into the water-rib.

The water-rib 12 is provided with a series of transverse tubes 19. The number, however, is indefinite, depending on the amount of heating-surface required and also the water-space desired. The water poured into the boiler passes down into the water-rib and flows around the tubes 19, and is there heated. The lower surface of the water-rib rests on a foundation and division wall 20.

21 indicates a mud-drum, which is secured to the water-rib in any suitable and mechanical manner, preferably, however, by flanging the upper portion of the end of the shell of the mud-drum and securing it to the end of the water-rib, and extending the lower portion of the shell of said mud-drum, passing the extended portion over the lower portion of the shell of said mud-drum and thereby substantially securing it. Said mud-drum is in communication with the inclosed space of the water-rib and also rests in a suitable depression formed in the foundation-wall.

22 indicates a cap which is secured to the end of the water-rib, and is provided with a m an-hole 23, through which a person can pass into the interior of the mud-drum and repair and attend to the inner structure, as desired.

24,25, 26, and 27 represent a series of deflecting-walls, which are constructed adjacent to the sides of the water-rib and at suitable and functional distances apart. The heat proceeding from the furnace-chamber strikes against deflecting-wall 24, which is arranged adjacent to the furnace, is deflected across to the opposite side of the furnace, whereby all the heat that is generated in the furnace is caused to emerge from the furnace only on one side thereof, as shown by the arrows. Said generated heat passes in a direction toward the rear of the boiler, strikes against the deflecting-wall 25, whereby all the calorific power is caused to pass through the front section of the transverse tubes 19 and then emerges from said tubes on the opposite side from deflecting-wall 25. The heat-rays that have passed through the front section of tubes 19 and emerged from said tubes again pass backwardly in a direction toward the rear of the boiler and strike against deflecting-wall 26, and are there deflected and caused to pass through tubes 19 to the side of the furnace from which they emerged originally. This series of deflections is continued until all the deflecting-walls have been passed, and then the heat strikes the back foundation-wall 23 of the boiler and is deflected upward and caused to pass through the longitudinal tubes 3, and all the heat that is not expended by being brought in contact with the coldness caused by the water passes out through the smoke-stack at, which is secured to the front end of the boiler.

By the construction as herein described it can be readily perceived thata great amount of heating-surface can be obtained without materially increasing the volume of the boiler, and the entire amount of such spaces is constructed and put together in compact form.

Having fully described my invention, what I claim is- 1. A boiler-shell, as 2, having projecting from its outer surface awater-rib, as 12, which communicates with the interior of said shell and is provided with a series of short tubes, as 19, passing transversely therethrough and arranged or grouped in separate series or sections, substantially as specified.

2. The combination, in aboiler, of a slotted shell 2, having projecting downward from and secured to its lower surface awater-rib 12, the rib communicating with the interior of the shell through the slots therein,a longitudinal base-wall 20 below the said water-rib, tubes arranged within the said water-rib in separate sections or series, an inclosing wall around the said water-rib, a source of heat communicating with the interior of the said inclosing wall on one side of the water-rib, and de fleeting-walls upon the alternate sides of the water-rib between the separate sections of tubes therein, as described.

3. A steam-boiler consisting of shell 2, horizontal tubes located in the said shell, a smokestack -it,secured to the same, a depending water-rib 12, secured to said shell and terminating at a distance from the end of the shell 2, transverse tubes 19, located in and a muddrum 21 secured to said water-leg, deflecting Walls 24, 25, 26, and 27 for deflecting the calorific power through said tubes, and a furnace-chamber '7, in which the calorific power is generated, substantially as set forth.

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