Application led November 15, 1907. Serial No. 402,289.
To all 'whom 'it ma/y concern:
Be it lmown that I, JULIUs KINDnRvArnn, a citizen of the United States, residing at Richmond in the county of Henrico and State ofy Virginia, have invented certain new and useful Improvements in Boilers, of which the following is a specication.
My invention relates to boilers, and more particularly to boilers designed for' use on locomotives. .As iswell known, boilers of the -tyfpe usually employed for this purpose are o l, comparatively low eiiciency, owing chiefly to the fact that they have a relatively small heating surface, such surface being composed wholly of the fire box and lire tubes.
The primary object of my invention is, therefore, to provide a boiler of the locomotive t pe, which shall have a larger heating sur ace, and, hence, a higher efficiency than those heretofore employed.
A further object of the invention is to prov vide this increased heating surface without increasing the external dimensions, or altering the standard sha of the boiler, whereby my im roved bo' er may be mounted on any well own form of locomotive, substantially without change.
A further object is to provide a boiler which canbe constructed more easily andy chea ly than the types now in use, and in whic the cost of maintenance will be re duced.
-A further object is to provide a structure in which the use of stay-bolts is largely eliminated.
A further object lis to provide a structure, by the use of which the emission of cinders from the smoke stack is greatly reduced. This is due to the fact that the increased heating surface renders excessive draft unnecessary, vand this also results in increasing the life of the boiler tubes J With the above and other objects in view, and to improvev generally upon the details of such devices, my invention consists in the construction and arrangement of parts hereinafter described, and illustrated in the accompanying drawings, in which Flgure 1 is a central, longitudinal section, through my improved boiler and firebox, the grate being omitted for clearness. Fig. 2 is a view of the same partly `in end elevation, and partl l in transverse section alone the line 2 2, ig. 1. Fig. 3 is a plan'orf the lower water drum, parts being shown in section. Fig. 4 is an enlarged sectional detail, substantially on theI line 4 4 of Fig. 2, showing method of securing drum heads. Fig. 5 is a sectional view, on a greatly enlarged scale, showing certain details of construction hereinafter referred to. Fig. 6 is a section on line 6 6, of Fi` 5, looking. in the direction of the arrow. i 7 is a section of the tubes, taken on line 7, of Fig. 5. Fig. 8'is a cross sectional view of the sealing strip employed.
My invention contemplates, broadly, the provision of a combined water-tube and retube boiler, and to this end I arrange watertubes within the re box, as now to be described.
Referring to the drawings in detail: 1 indicates the usual boilershell, having the combustion chamber 2, and fire tubes 3, extending therefrom.- The rear sheet 4, is carried downward to form the front wall of the forward waterleg, while the rear wall comprises a sheet 5, bent over on the sheet 4, and flanged internally to form the mouth of the combustion chamber. Therear waterleg is formed by the usual mud ring 6, and sheets 6 and 7, bent and lapped as at 8, to form a fuel opening. All of said sheets are secured by means of the usual rivets, (not shown).
Extending between the front and rear water le are a air of upper drums, 9, and a air o lower rums, 10. By reference to Flg. 2, it will be seen that the upper drums are lar r than the lower, and are dis osed relative y close together, while the ower drums. are located at the extreme sides of the boiler. This arrangement is referable, as it permits of great width of re-box between the lower drums, and at the same time, produces a structure which conforms to the standard shape of the locomotive type of boiler. The method of connectin these drums with the water legs, I regar as an important feature of my invention. The rear sheet 5 of the front water leg is cut and turned up so as to form flanges 11, and 12, which embrace the ends of the upper and lower drums, respectively, and to which the same are securely riveted. This is clearly shown in Fig. 3. The sheets 6 and 7, forming the rear water leg, are rovided with palrs of similar out-turned an es, 13, 15,
14 and 16, respectively, and the rums pass-"110 entirely through this rear water leg, and, terminate .substantially flush with the outer f its correspondinglower drum, I arrange a series of water tubes, 24, beaded into the` edge of theflanges 14, 16, as shown in AFig. 3. By reference to this lignite also, as well as to Flg. 1, it will be seen that in that portion of the drums lying between the sheets 6 and 7 within the water leg, I forni a series of lar e openings, 17, extending all. around' te drums, and serving, as is obvlous, to establish communication between said drums and said water leg. Within the rear endv of each of the drums, (as 9, Fig. 4) I fit a flanged ring 18, and secure the same in place by means of a series of rivets, 21, passing drums. I preferably dis ose these tubes in rows, (three being shown and the tubes of the inner rows may, or may not have their ends swaged or reduced,` as found desirable. Although they are so shownin the drawing,
l it is to be understood that I `do not Wish to be limited to this (construction. It is, however, desirable,` that the tubes of the oute'r row should lie as close together as possible. To this end, therefore, I taper or swa e the ends of these tubes from, say, 2g inc esto 2% inches, or any suitable amount, and also place thev outer holes, 26, in the 'dnlmvery' much closerl together than the :inner holes,
' 27.` (See Fig. 3.)
It Awill now be understood ,that I propose f to utilize the space lcetweenfthev two outer 4. Y opening between them.
yrows of tubes as the ire-box, and have these .outer tubes constituteythe side walls thereof.
Hence, I space the tubes in the inner rows well apart, so that the heated products of combustion may readily circulate between them, but the tubesvof the outer 'rows I arrange so that `thereis only a very small As to the method of arrangingy the-outer rows oftubes and associated parts, reference is hadto Figa, 6, 7 and 8. Of these, Fig. 5 is a view looking from the outside of the boiler, and shows a ragm'entjof one of the drums, 10, at one end, where it entersone of the water legs, say, for instance,V
where it is secured to sheet 5 ofthe forward water le The construction of bothends of allthe ruins is the same so that a descripf tion ot' this one will su ce. The drawing clearly shows the ends of the outer row oit tubes,"24, swaged as at 25, and beaded into section, and o the drum 10. Rivets 28, secure the drum to block in position. The crevice between the body of the tubes I ill by means of a sealing strip, 31. This,`as shown in Fig. 8, consists of a strip of ta ered or wedge-sha ed crosssubst'antially the Il thel tubes, formed of copper soft annealed iron, or other suitable materlal. This'strip isv inserted between two tubes, and then its thin edge upset with a calking tool, so as to form an effective seal between .the tubes, as shown in Fi 7. I regard this as one of the important eatures of the invention.
The space between each end tube and the corresponding water leg is filled by means of a cast iron block, 32, preferabl divided into two or more sections. along one edge, against a series of studs35, screwed into the sheet, such as v5, of the water leg, and at its other edge,-it is radiused, as shown at 40, so as to conform to the shape of the tube 24, againstwhich it seats. This block is provided on vits inner face with a suitable chamber in which is laid fire brick, 33, or some such material, held in place by means of bolts, 34, let into the same,
ength of This b ook rests,
and securedto the block 32. Lugs 37 are carried'by said block on its other face, and resting against the two series of lugs 35 and 37 isla sealing plate, 38, one edge of which abuts against the wall 5 of the water leg, while the other edge is radiused and ogeed, as indicated at 41, so as to conf fit snugly against the tube, 24, where it is swa ed. Bolts 36 extend outwardly from the lock 32, and project through the plate 38. As this plate is preferably formed of sheet steel, such as boiler plate, it will be seen that by tightening up the nuts 39 on the bolts 36, the plate 38, which is slightly bowed, or conca-ved, will have a tendency to straighten and thus elongate, and in so doing, jam between the sheet 5, and the tube 24, thus forming a tight seal. This is necessary in order to revent the leakage of outside air into the re-box, and I regard this methodvof forming a seal as an important feature of my invention.
Referring again to Figs. 1 and 2, 42 rep resents the usual, or any ldesired form of te, supported on an I-beam, 43, secured y means of bolts 44, to a series of brackets preferably six or more, are equally spaced crm to and 45..A These brackets, of which there are along theside of the `lowerv drums, 10, and secured thereto as by means of stud bolts 46. An' angle bar 47, extends the length of the drum, vandis securely bolted to the brackets, 45. From the other Hange o this bar is adapte supported the usual ash pan, 48, by means of bolts, 49, passing through sleeves, 50.
Extending around said drums, 9 and 10, and
outer row of tubes, 24, and spaced apart therefrom is a sheathing or casing, 52, serving to cover and hold in position, sectional magnesia lagging, 51, or other heat resisting material.
In order to protect the rear wall of the forward water-leg, and, also, to deflect the flame, and cause'it to spread through and around the water tubes 24, I arrange a batlie plate, or fire wall, 55, constructed of fire brick, and supported on water tubes, 53, 54, in an inclined position, as shown. All of said tubes extend from the forward Water leg, upwardly and backwardly, some of them, as 53, having their upper ends beaded into the drums, 9, while others, as 54, conneet with the rear water leg.
Wh'le I have thus described my improved boiler fully and in detail, I `wish it distinctly understood that I do not limit myself to Such exact details, but contemplate the sub stitution of any and all such mechanical equivalents as may fairly be said to fall within the spirit of the invention, and the scope of the'appended claims.
It Will thus be seen that I have provided a highly efiicient, and economical boiler, having many points of superiority over those now in use, and it is thought that the numerous advantages thereof will be readily appreciated by those skilled in the art.
