Description
(1) ?’v all wkorn it may concern:
(2) Be It I:nown that I, ‘W iLLIAMi C. COIL.L1N, ai citizen oif the U~nited States, residilig at W ichita. in tile county of Sedgikcl and State o>f Kiansas, have invenlted certain rtew anud u.’sifrr lup;rovemnents in Lampls, of tx i 11l the following is a specification.
(3) ”lie present inivention relates to vapor lamps, anid inore particularly latnpls of the type disclosed and claimed in my co-pend- }ng application, Serial Nro. 506,295, filed .Judy 7, 1909.” Ii 0o1e aspect, this inlvention involvIes certaini inlprovenients over the structure illustraitedl in said atpplication.
(4) One of the primary objects is to provide certain safety features, whereby danger of exp~losions is redluced1 to a lntinliln, in thle first Iplace, IW” producinlg an exceedini~ly strong font, inl which the fuel convcey ug standard constitutes practically az tie bolt betwecn the top and bottom walis afi saidl font, secondly, biy providing mleans .’hicl will effectively cut o1£ the flow. of fuiel fromt the font, in case the upper portion of thle lamp structure becomes broken off, and thirdly, by preventing accumulations of licluid fuel in the fluxing chlamb~er and pro- durinig a pilot light w”}ich will insure a .nitintcenance of the flames at. the burners.
(5) Still another object is to provide novel, simple ani effective means for supporting the shade by making certain elements of the lanlip :structlue perfurni the functions of sus- . )eig (levices.
(6) AnI ernaidiment of tile invention that is iruving entirely satisfactory, is disclosed in the acconlpanyillg (rawings, wherein :

Sunitable supp~ort- ing; feet 15 of yielding inaterii atre secured .E to the flanget~. ;t coniifled filling nipple and air jfrimpl covupling 16> is mounted upon one side of the font, some distance below its uipper endl. A. tubi lar” standarud, designated as a whIolc by the reference numieral 17, pro- 0 jecrts upward centrally from the font, and in he formIt illu-trated, coinpri~es sections 18 andI 1J, the ,cct ion 18 benug dlisposed1 within the i’ut.±, lhe Section 19 being arranged ,ubox c the smru, anti said sections bie- ‘

A niut ha;s a head :: bearing; 0 against tie lunder sidle of the bottom and a nc1c5l 23; that extends thlrought said bottom2 and is threadled into the lower enid of the sectiont Is. ‘This neckt is provided -;it h inlet “i)O~ts :’. that eotnnitunicate with the interior of the fornt and writh the interior of the -I anida l'(1 2,etioii. I L wi}i thus be C:~ idctit thtt rte oil or liquid fuel undler pressure within tile font wi}l he forced upiwardly thrvuryh the stail(vltrd. At portion of the staindard (Ti- rectly above tlh “rap 31, is preferabl”y sur- roul(ed by a hanle: sleeve 25 that bear.

(14) Connected to the upper en11( of tha standard secotion ii) ;old ron-titttig an estension thereof., is a ve “ial vaporizing; tube 2 8, within whicdl is placed a wick. T’his wick 04 pireferahbly ciornp;”ises a metal core rod 29 5irouudleld by asbestos 30. The valorizing tuhie, ben staih, it will be evident that tde wvick: mna he inserted into and removed from the upier end of said tube. Located bielow the wick, and preferably at the june- tiure of the vaporizing tube with the section 19, is a valve seat liug 31 having an upper ?”alve seat 32. anid a lower chamber 33. A’Ir- rangedl in, this chambfer is a ball valve 34 that noirnally rests upon the bottomn of the chainbor, so as to pei”1uit~ t;be fr e upward passage of the liquid filel from the font into the vaporizing tube, as “hereinafteres *plained.
(15) Detachably threaded upon the upper end b of the vaporsizing tube, is a couling head “”5 having a horizontally disposedl vapor passilgt’
(16) 36 surrounded by a valve seat 37r, said passage terminating in a downwardly extending outlet 38, to which- is coupled a vapor to delivery nozzle 39. The coupling has a horizontal extension 40 carryinug a pac>king gland 41, and through this gland extendls the stem 42 of a valve that is threaded into the extension and is movable into and out of coaction with the seat 37. A ktnurled head 43, secured to the outer end of the stem, constitutes means for actuating the valve. The nozzle 39 is threaded upon the coupling, and3 has a small di schiarge orifice 44 surrounded by an upstanding, boas 45 fitted within said nozzle. TIhe nozzle tie- pettds within the horizontal inlet stein 46 of a vertical Bunsen, or combined air and vapor conducting, p~ipe 47 that is disposed alongside the vaporizing tube 28. Thiis pipe 4 i is threade d through the top of a mixing chamber 48 that is thus supported by the pipe, the Lower end of said pipe extending downwardly nearly to the bottom of the chamber. The tube 47 is su’~portecl by means of a collar 49 that surrounds the vapori-iing tube 28, and is vertically slidable thereon:, this collar also surrounding a fired ” thimble a0 carried .by the vaporizing titbe 2S and having a peripheral groove therein.
(17) An outstanding set. screw 51, htavin a con- lpara:tively long stemn, is threaded thrnought the collar and engages in the groove of the thimbl1e, thus holding the parts in tht position iillustrated in F+ig. 2.
(18) The chamnber 48 has a bottom openinlg nior- mally closed by” a plug 52. antd is also po vided with outstaixling nilpples 5,3 cotmnuni- .cn~n kih its uIpper jxortion andt catrrying_;
(19) B5depending burn”=rs 54 that also constitute mantle supports, said burners being disposed oin opposite aides of the vapcrizing tube 28. The chamber 48 futrthermore has in its tower portion s vent openingr 55 conl- stitutirig a drain thtruugh which any liquid in the chamber cait discharg;e. It will b~e observed by reference to Fig. 5, that th:s vent 55 is disposcd dlirectly oppousite to the vaporizing tube 28S. The reason for this arrangement will h~e explained in the dlescrip- tion of the operation of the lamp.
(20) The shade for the lamp is designated 56, and is carried as usual1, by a suspending ring 57 having set screwcs 5i8 that engage the upper portion of the shade. This ring is prouvioed with openings, one of which is tles- :gnated :,9, which opening receives the outer end of the air inlet steri 46, the air regulating device 60 being detachably thtread- ti6 ed on said end. Another opposite opening 61 receives the outer portion of the set .ce stem 51, and an outstanding pin 62, carried by the cr.llar 411 and shown in Fig. ?,, es- tenils thlroug;h anotherr op~ening G3. It will thus be seen that the shadle supporting r:,g :,i is suspendled by the ~et =cr,-;. the stern -Ii tiid the pin G”3. ‘I’lw ltcail :+ fiiitliertorr is Jpro?”idcd with an iiipst Ufllin ri o~ectiutt 64. into which is thraded the stem G55 of a bell 6. this hell carrvi’ig a1 terminal ring Gi, by means of whicht the lamlp may l+e sirs- lpenled if d~siredl.
(21) The operation of the struc~ture is substan- “tiatllv as follow;s: Liqulid fuel is placed in the font 11. and is placed tunder air pressure. Sc A~s long as the valve 42n is closed, no fulel can pass through the lamp, hurt if sa:id valve is opleci. this fuel will puss upwardly th rou~ll the standard into the v”aporizer. Thiii vapor- izer”, bieing initially heated by arty suitable 8J nlea ns. will change the liquid into caper.
(22) which kvill l).+s throuigh the passagec G,6 atiM discharg.e olonnard ll} fruiii tlio ncozzle :;’.
(23) Th’le comparatively small orilicec -1 will create a retarding ptrs~irre in the vaporize~r.
(24) so that the op??:ard low?? ” of liquid fuel th ou r’ theo si a n,l a ro I , iile excedin a lv ,iow. and coriseojuentlv :ie valve :;4. shown in h;. . ,?ilt] nr’ainlt~:’ its iflolerative position. periiiitting tlet passage of the fuel.
(25) The vapor passingr donwardly through the pipe 47, will carryv air with it into the mixing chlibcr -t8, and the v;aporized fuel will pass fromt said t’hainber through the niphti~s :>: to the bnuers, where it wvill be con’,uried.
(26) thu+s niati1iliuing the usual mantles in in- candlOsccflt c ondition.
(27) It v:ill be” rioted thlat a single coutrofling valve 423 is employed in the structure, ivhieti valve regulate=: the vapor, as wvell as con- o trols the passage of fuel through the lamtp.
(28) Als a re~uiit. the light can be turned uip or down, or inunedi:;tely extinguished byT meoans of said valve 4t2. The arrangement of the valve moreover p~laces the patck~ing 11 and the handle outside the range of ]teat fromi the burner”.
(29) r’hlre are a number of impOlant advan- tage~s fur this structure, among lthicht may be me~ntioned the, following. The font is exceedingly” strong to withstand any inter- , niil pressur~e that may be brought against it, the standard] constituting am central ‘vie bolt. 7’Ie valve 3-4 also adds to the security of the device. As above explained, as Long as there is a retarding pressure in the va- porizer, atnd the oil feeds slowly through the standard, this valve 34 will be in its open position, but if through any accident, the ‘upper portion of the lamp structure 22i shotuld be broken off and the pressure thereby relieved above the valve, the increased force of the flow would cause the valve to seat and cut off such flow. The vent 55 is also an iniportant feature, and performs twvo 130O b~urners, and into the range of the fuei flow- irr firmi .mid burners, as illustrated in i”‘ig.
(30) 5.v Now it is a well kntown fact that to securre co~n plete comzbustion at the barner, the rnixtur-a of air an~d ” apor is such that tle – the larre is confined by the mantle, it i=’apt blav’ o$,.” or in other words, becomte e -:ingiiisiied. It may~z sometimes happen t] tt om=. or both tmanitles becomtre ac- cjdrtttalv broken wh~len there is no one ” about to ncotire the same,. and were it niot for the pilot Iighit, te, lamp might beco~me e%- tiztgi.hecd, as ab~ove esplained. The va- Iize22 as 2 COn2sequtence. wou~tld beco~me cool}, fire liqutid5 feecL wuld flowc npwardly there- thr”e g w:c-harge front tha nozzle Into the :30 u’i~c cham{“er, and thus flow; dlown unAOn the outside o]” the lamnp. Should an afcci- cnt. of thiis kind occur with the present Str’ttUre, te pilot Light above; described, waoruld ma”tint~iin the bunrners lighted at a?1 times, ;and thus overcome the .objection above described.
(31) Ift will be noted that in thin mechanism, th~e features of t}:e lamp structure are emi- plovedl as supporting n’eans for the shade, 40) rhu reducing the number of elements and eciirig a uhmetcncal structure.
(32) Als an iradjeatio.n of how; the mechanism utan b~e mtrxifiedl, attention is invited to F’irs. rIt? incltsiveP. In Figs. 7 and F, the :;vaporiring, te 28 has the controllintg and c:,t-off’ valve easin g”,8 secures] to its upper +”,d. thie valve 42u being. horizontally dis- pInr ed as behfre. The vapor conve’:ng ~nie:, :,(i t+”iniit,atto in a dow-narc<Iv es- ten+[ing nrle 39a~ that is introducedI into l,+” ut~per tf’flr’i’ ot e atir andr vatpir-condutct- itns pike 47i= x’hichi lpile has a horizontal ini:”t step, 4i . In tlii= form of structure, it w ill be u{b-rrv”r that theP valve is arinned 5~5 betwven tiems vaporiziug :tibe anr( noz~le, u one s,,irl the. T},e ilpe Ii’ has a collar 4! +’ -urronding the ttub”e and held in place ia -et screw 53a. The collar a?:=a carries ant rnii~tarucling pin U2a. The 5tein 46″, set (/i rrew 5:b aned pin d2″ constitute the support for the shade ring indicated in dotted lines, and designated 57a* In Figs. 9 and 10, the rarransemert more closely anprosimiates thatf cdisclos-ed in Figs. 1-6 intclusive. The ‘,aporizintg tube is designated 28°, and has ing the shade hailing s ing :,i °.
(33) trom the. foregoing it t5 thouttht that the construction, operation and many’ ad- van~tagev of the lueretn dctribed inverntion will be apparent to’ thase skilled in the art, without fthtor descriptiosn, and it. will be understood thi~.t various, changes in the size, shape, pro~por”tion and mtinor details of cont- stz-rui maybe resort..d to wvitout departing from=n the. spirit or sacrificing any of the ad~vantages of thee ir.vention.
