LESTER E BUD, br imrwmmmrrirefiemf.
ernennen-noon' nppncatipii mea .my A14,
To all whom t may concern.' Y i.
Be it known that; I, line'xnnlil.A Bunn, a citizen of the United Staten, residing at Philadelphia, in the county of Philadelphia '5 and State of Pennsylvania, have invented certain new and useful ImA rovements in Furnace-Door Arches,' of which the.fo1low`- in is n specification. v
u'ch trouble and expense has been caused b the frequent breaking .and Vfelling down oi7 the door alrches 'of furnaces.
One object of m present 'invention .is to so make a. furnace oor arch thatitwill inst for an exceptionally long time; :4
Another object is to so lconstruct my 1mproved arch that it will belrept comparatively cool and will alsoprotect and fermenti-ong support forthe brickwork and well adjacent thereto.
These objects, and other. advantageous; ends which will be described`l1erenafter, I f attain in the following manner, reference' being` had tothe accompanying drawings; in which- 'i Figure `1 iev a fragmentary elevation viewed 'from the interiorofl aV furnace shone, ing the side walls in section and illustrating? an arch structure made in .accordance-:Mit my invention,
Figure-2 is a section taken on the line of Figure 1,
Figure is a section taken on the line 3 of Figure 1,' l
Figure 4 is a, section taken onwrthline 4-e of Figure 2,
Figure 5 is a, sectiontaken on-1tne luie 5 5 of Figure 1,
Figure 6 is a detail toplplen view of one of the arch tops shown in igures l to 5 inelusive,
Figure 7 is an inverted plan view of the arch top shown in Figure 6, h
Figure 8 is an elevation showing the inner face of said arch top, end4 Figure 9 is an elevation showing the outer face of said arch top.
In the drawings I have illustrated my Vin. vention in the form of a two-door arch structure.
Referring to the drawings, 'l0 represents the side Walls of c furnace und l1 is the front plete which when used in connection with a boiler is known as the boiler Jr'ront.
In carrying out my invention I provide n dead plate 12 which has its opposite ends illustrated 31nd isf'sneced betwemathenpier 1921. semi n4514541.;
(ill
in this manner a passageway or channel 29 is formed between the inner` surface of the front-.plate 11 and the surfaces. 30 of the arch tops; said channel being arcuate and extend-` ing in the direction of the length of the arch tops. The channel 29 is open et its bottom so as to communicate with the space provided by the doorways 26. Each'o the arch tops 22 and 23 has a plurality of ports or m0 passageways 31 formed entirely within its yI thicknesssaid ports extending from the front surface 30 to the rear or inner surface 32. Thus the ports 31 communicate with the channel 29 and with the interior of the fire box 33 above the dead plete 12 as clearly shown in Figures 2 and 3.
In euch by the arch tops the ports 31 nre intersected oy e longitudinal pnmgewny 34 which is formed entirely within the thick- 1U endspcrtion'esczpostgaupongthe Sm The arrangement ness of the arch top end which is open at its opposite ends so as to communicate with the passa-ges in the piers as shown in Figure 4.
In this manner the ports 3l communicate with the channel 29 and with theinterior of the lire box 33 and also with the longitudinal passageway 34. The longitudinal passageway is in communication with the passages of the piers and also with the space 35 below the dead plate 12; said space 35 `forming the :ish pit of the :furnace in the usualrmanner; said front plate 1l having :ish doors 36. I preferably locate 'the ports''il'closer to'the top surfaces of the varch tops thanto tlie'bottom surfaces thereoso'that acomparatively large portion of the'metal is presentl directly over the doorways and the strength of the arch'tops i-snot impaired.
'I 'have found by actual use and installation that yarch structures'made in accordance with the above will last, even under A.severe operatingconditions, ffor a far greater time than other `known metallic arch structures. rovdes cooling means since air can circu ate through the piers, urch tops'and deadiplate `so.that'thet'einperature will-*be equally distributed atpractically all portions of `the `archstructure11sfis believed to 'be obvious from the illustration and 'foregoingdescription. In addition to this, the furnace -fton't isrlrept comparativehI cool since the provision `o'f the channel 29 serves 'as LAbreach in the :arch -top structure and also serves-.to-provide a coolingas'pace'between lthe lmajor 'portions vof the arch top and frontplute l1. I'n addition'to this, fthe brickworlr above Athe Iarches fand also adjacent the ends thereof-Will beprotected und consequently will last for a great 'lengthof time While I have -described my invention as taking ra :particu-lar form, it Vwill he 'iincl-erstood that the various -parts-offmy invention nia-'y rbe Jchanged -Withou't departing "from the spirit thereof, and hence -I do not. limit fmyself to the precise construction set forth, but consider that I am at liberty to make such changes 4land alterations fas fairly come within the scope of the appended claims.
Having thus described my invention, what I claim as newend desire to secure by Letv ters Patent is 1. A'fur'naceerch structure including a top, piers supporting the top, a dead plate supportmg t eV piers, the iers having upright passaves com'municatmg with the Vlash pit and. with ports-leading to there 'box, the dead plate having slots communicating )1i-ith -the upghtvpassuges, and the top fliermg-po'rts extendingffro'm front to rea-r thereof communicating with 'thedoorway land tlfe fire box. 4 i
2. A furnace arch structure including top, piers supporting lthe `top und havin I'pussages communicating with the ash 'p1t, Athe top having ports c'oInmunicat'ing with the doorway and `the fire Vbox Aand la transverse passage communicetin with the ports `and with the passages in 't ie piers I 3. A furnace `-areh structure lincluding a top, piers supporting -t'he top 'fand Vhzwmg passages communicating with 'the asl1.,pit, the top-havinga forwardlvyfextending flan-ge abutting the front plate and, forming f'a channel communicating with -the doorway, ports commumcating with'tle'chennel :and the lire box and fa passage Iinte-rsecting the ports and communicating with 'the .passages in the piers.`
4. A `furnace arch Astructure including a top vhaving l orts lcommunicating with fthe doorway Aan -jthe fire -box and -a transverse passage intersecting theports.
In testimony whereof I have vsignedmy name to 'this 4specile'etion in the fpr'esenceof two subscribing witnesses.
