vTo all whom tmay concern:
Be itlknown that I, JOHN PIERCE, dr., a citizen of the United Dtates, and aresident of South Norwalk, vin thecounty ofV Fair-v field vand btateV of Connecticut, have 1n- Another object is to provide for the generation ofgdrier steam by producing a boiler having a,low steam Contact with the water. Another objectisto prevent water enter- .ing the steam [drum when the boiler is placed at an angle as when an automobile `is 'on a-hills1deor a yacht 1s rolling 1n ka heavy sea. f
Another object Ais to construct a boiler having high j thermo efficiency `and perfect circulation under-all conditions. f
A .further Objectis Yto produce a high pressureboiler having the right proportions of water "and steam for fast steaming.V
VA still further object is Yto provide means wherebyv anyofthe headers and connected v,011@ 0f the. Sections;
tubes may be easily removed and replaced. Other objects and advantages will be apparent as the description proceeds.
Intheaccompanying drawings: `Figure 1 is a front elevationof the boiler, vparts being broken away; Fig. Qis a side elevationof the same; Fig. 3 is a top plan view;- Fig. 4 is a fragmentary rear elevation, parts being shown'in cross section;
,Fig 5 is a detail section of one ofthe headers showing the angular relation of the bent ends of the tubes weldedK thereto. t
Fig. 6 is an enlarged fragmentary View of Y v MView of one of the connections V,between the steam .drum v and headers.
. `Referring to the drawings, al feed water intakepipe 1 is shownconnectedtoone end Fig. 7 is a .detail of a Vfeedwater distributing drum 2 located at the bottom or intake end of my improved boiler. t Y In order .tor distribute 'the Water rapidly and uniformly to the entire boiler. I- construct' the'same of a number of sectionsl 3,
each section comprising a vcomplete f unit consisting fof ra vertical .tubular header v4 Vand steam generatortube's 5. Ten sections are shown in the drawings but any number v may 4be used, `depending' upon .the horse power of the engine to ,be driven.` l As the sections are identical in constructionthe description of one willsulce for all. i
The vertical tubular headers 4 are conthereofv and connected to the 4top `of "the headers V4`by the short sections ofltubing. 10 and-12' and a high .pressure union v11 slniilar to the one 7 above described. f
In order to feed, to the engine the hottest and driest steam possible, VIplace asteam discharge pipe 13 at-the highest pointrin the steam drum 9, so that the steam yunder pressure at this point can pass through openings 14 'in the steam discharge pipe 13 @and through saidpipe 134 to the engine not shown in thel drawings.
`'llhe steam generatortubes 5 are `formed of a single piece of seamless steel tubing bent `to ,form a loop, one-end being welded to they header at 15 and the other endat 16. The point y16 being v,higher than the point 15, the loop 17 is consequently disposedat an angleto the vertical header 4. The angles of curvature indicated by the reference letter A in Fig. 5, represent `the angle of least resistance to the circulation of water and steam. '1`he' curvature of the ends of thetubes 5 also to lool; said ends are placed in the proper openings 18 in thevertical 'headers,'prior to welding.
Toprevent any strain being placed on the generator tubes and their connections to the verticalA headers 4I "provide depending hangers 18y boltedv at their upperends as at 19 Yto a horizontally disposed I beam 20 secured to the boiler casing, not shown; and in properly spaced "relation to one another are tube supporting stirrups 21 designed `to take up all vertical vibration of the tubes 5.
` Some of the heat applied to the boiler will'V pass directly up through the space 22 between the tubes 5 until it reaches a bafle plate 23, when it will be deflected to the adjacent section. rlhe baffle plates are made of a suitable heat resisting material and are placed in staggered relation throughout the boiler so as to obtain all of the heat possible from the fire.
` In operation my boiler is simple and eflicient. Water is fed in through the feed water intake 1 to the feed water distributing drum 2 and is in turn fed to the headers where it rises to the level indicated by the reference letter L. The waterlevel L gives the right have thehighest possible thermo efiiciency,
as will be seen as the vdescription proceeds. My boiler has a greater heating surface in a given space than any boiler of its type.
' Heat is applied to the boiler in the usual vof the heat as possible. i Y y 'passes under the steam drum 9, around the way and passes upward as shown by the arrowsin Fig. 2, around the baHle plates 23` and 'out at thetop. The bafile plates 23 retard the progress of the heat upward passing it to the next section and giving it a rolling action throughout the boiler, thus giving the' tubes a chance to absorb as much The heat then unions 11and the tops of headers 4 and finally to the atmosphere. vAs the .heat passes around unions 11 and the tops of headers 4 it further heats the steam, thus reducing the possibility of moist steam lreaching the steam discharge pipe 13.
A perfect circulation of water is made possible by the particular angle at which the generator tubes are placed in relation to the headers 4, this angle is indicated in Fig. 6
by the reference letter B. In this connection it will be stated that as the water passes from the header into the lower leg of each of the tubes,y it is heated and passes back and into the headers by way of the upper leg ofV each tube. The lvaporized product passing y from lthe latter rising in the header while p thatv part of the water not heated suiciently to vaporize will drop or fall and rthereby again circulate through the tubes. Thus the water will circulate through the various tubes until it has been vaporized and that boiler.-
the quality of the heated products will be free from moisture. The circulation is also aided by the provision of tubes Ahaving the same size inner bore free from sharp angles or projectionsof any kind, rllhis increased circulation not only .aids fast steaming but tends to prevent sediment settling in the tubes. i The generator tubes 5 above the water line L contain only steam which is fully dried and superheated by the action o'f heat Vagainst said tubes giving a higher pressure than obtainable by methods used in the past. A low steam contacty with the water is due to the arrangement of headers 4and gener- 4'ator tubes 5 as illustrated, further aiding the production of dry steam and as the steam is not in direct contact with the main bodyV of water saturation is prevented. The steam drum 9 is placed high enough to prevent water entering when the car is on a hillside at vany angle. I have provided the steam discharge pipe `13 to take the steam from the 'highest point in the steam drum 9 which-is supplied from the various sections 3, thus equalizing thel pressure throughout thesystem and minimizingthe tendency of an engine to prime or draw water from the My boiler vsections 3- are demountableand interchangeable at rall times so that quick repairs may bek made without removing be removed for repairs by unscrewingthe unions-7 and 11 and if desired pipes leading thereto may be plugged and the boiler operated as before without decreasing the efii- 'boiler from car. Any ofthe sections 3 may ciency orpower of the remaining sections. 1
,Inl assembling my boilerI prefer toy use seamless steel tubing of high tensile strength for my feed water distributing drum, head-` ers and steam drum with their ends plugged tubes vare also of seamless steel tubing properly annealed before and after bending.
'The angle indicated bythe 'letter Ain Fig.
1 serves a double purpose;'that of aiding the circulation and'also as a locking means for holding the tube inposition while being welded. y
It is to be understood that the Vform of my invention herewith shown and described and welded as illustrated.v The generatorf is to be taken as a preferred example of the Y same, and that various changes in the shape,
size and arrangement of parts may be resorted to without departing from the spirit of the invention or vthe scope of the subjoinedclaim." Y
Having thus described myinvention, what I claim as new and desireJ to secure and protect by `Letters Patent of the` United States, is: Y
In a steam generator, a horizontally disposed water distributer head, ,a steam drum arranged above the distributer head and in parallel relatonthereto, a plurality of parand parallel to each other, one leg of each allel vertical headers communicating with tube being secured to the header at a point 10 the dstrbuter head and steam drum, a plubetween the legs of the adj aeent tube, so ralty of horizontally disposed U-shaped that the unvaporzed products passing from circulating tubes communicating With each the upper leg of each tube Will fall and pass of the Vertical headers, the planes through into the lower leg.
