7 Specification of L'etters'latent. Pat t 22, 19 1 Application filed September 29,1914. Serial No. seiloss.

T 0 all whom it may concern v 7 Be it known that 1, HUGE S. S rUD ERT, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, haveinvented certain new and useful Improvements in Steam-Boilers, of

Iwhich the following is a specification.

My invention relates to steam boilers, and

comprises the novel parts and, combinations of parts which will be hereinafter part1cu- I larly defined by the claim.

Theobject of my inventioihis to provide a stronger and more efficient steam genera tor, especially for mar ne bo1lers,-one which will better stand the racking motion. ofa vessel, and one which can easily be cleaned and inspected.

Other objects will appear from a study of the specification and claim.

In the accompanying drawings, I have shown my invention in the form which is now. preferred by me.

Figure 1 is a side elevation of my boiler, part of the casing being removed and part being shown in section. Fig. 2 is an end elevation and partial section of my boiler.

clean, and yet strong enough to stand the racking and quivering of the vessel. They must also be eflicient and economical in operation. My boiler is designed to include all of these desirable features.

I provide a steam drum 1 which is of sufficient length to project through the ends of the casing 7. This drum 1 is provided at drums l positioned at each side of the boiler, and to which they are coupled by T- flttings' 22. This forms an inverted U- shape connection between the, steam drum 1 and respective mud-drums 4. The pipes 3, however, extend directly downward at each side from the drum 1, and are connected to mud-drums 4: by T-fittings 32. This forms an inverted V-shaped connection, and the pipes 2 and 3 to supportjthe drum 1, andhold itfirmly in, place against vertical and lateral strains, 1

The steam generator proper consists of a series of. coils 5 connected with the muddrumst by. risers These coils are each constituted of a plurality of pipes Which ared1sposed'in inclined positions, as shown,

to facilitate the circulation of the water ashort distance of the center of theboiler;

Instead of each individual coil vbeing di-- rectly, connected with the. steam drum, a group of coils preferably two, are joined at 51 by any suitable connection, and thence a singlepipe 52 connectseachpair of coils with the drum and at adistance above the water level therein. A doubling plate 13, so called, is advantageously provided to reinforce the drum where it istoppedtoreceive the pipe connection 52 to compensate for the borings in the drum shell and afford greater lengths of threads to. engage said connection. In marine boilers, it is desirable that they should occupy very little space, be easy. to;

To better distribute the - furnace heat 6 and 61 arranged in a peculiar manner. Two plates 6, one on each side of the boiler, extend horizontally just above the generating coils, from end to end of the boiler.

These bafiie-plates 6 are of widths to pro-v vide passages for the hot combustion gases between their .inner sides and the steamdrum 1. A baffle-plate 61 is placed on a plane below the plane, of plates 6, and ex tendsfrQm the rear end of the casing tov within ashortv distance from the front end thereof. This plate 61, however, does not touch the sides of the casing, but extends outwardly fromthe center on both sides but part-way to the sides of the casing. More particularly, the baffles 6 and 61 contribute to direct the currents of heated gases, causing them to flow forwardly and laterally from, and then against, the drum before estherein and promote the flow 0f-the gen- 'erated steam to the drum 1, and are" ar'-' ranged in the fire-box to extend-to within among-the pipe coils, I provide baflie-plates caping by stack outlet 75. By such device, a more effective heating of the coils and" steam drum is attained than would otherwise obtain.

The casing 7 is provided with openings 71 at front and rear for the projection of the steam drum 1. This casing is also provided with the usual openings, as the furnace doors 72, ash doors 73 and cleaning out openings 74. v

I have left a space 7 6 between the cells 5, the casing 7 and the steam-drum 1. This will allow a man to enter through one of the doors 74 to inspect or repair theboiler.

12. This battle-plate extends downwardly in front of the dischargeopemngs and is arranged sothat the.water andsteam discharged from the generating coils 5 will lIIl-' pinge upon 1t, and be deflected downward,

as the pipes 52 are placed above the water level in the drum. The fluid thus 11np1nging the plates will ina measure, effect the separation of the steam from the vaccoinpanying water, the water discharged from the coils fallin into the bod T ofwater H1 the drum while the SiLQHHI'Will mingle with that'in the drum. tobe led-0t? through pipe:

14, and accordingly obviate the discharge of saturated steamfrom the boiler.

if it is desired to remove one of the coils 5 for any reason, an operator may enter at 7% into space 7 6 to d1sconnect a c011 at 55 or 54, and, by entering the door 72 into the boiler furnace, the respective pipe may be unscrewed for the removal of the coil. viher'e convenient, the side of the casing 7 may be detached and the coils taken out Very easily; otherwise a coil may have to be sep arated into parts which will pass through one of the casing doors. In this way the Gopies of this patent-may be obtained for five cents each, by addressing the Commissioner ofjPatents,

coils may be quickly andeasilyremoved for 1 repairs when necessary. 7
