' shaped lpieces such as stove Alegswhich must be y placed on enameling racks outsidevof the furnaceand then charged by suitable means as yby a charging fork.
In accordance'with thepr'esent yinvention I propose to 1provide means for adapting the standard permanentl -rack type furnace @to the ename'li'ng of small irregular shaped piecesby providinglremova'ble capping bars which are placed on the pins ofthe permanent racks to constitute supports fory lthe removable racks whichmayfbe ,placed thereon by fthelchar'ging fork. It lis .among the objects of the invention 'to provide affurnace structure adapted foruse as astandard j permanent rack 'type l.enameling' lfurnace.and which is readily convertible toa removable' rack 'type furnace in accordance with thekind of ware itfisdesired to fire. i
Another objectof the invention isto provide a plurality of sectional cappingbars which are provided with seats for engaginglthe pins of the permanent .rack .andwhich arev longitudinally disposedin'groups and arranged in transverse spacedrelation to constitute central and end portions for the removable rack members.
Another object of the invention is to provide a charging fork with capping bars to adapt it for handling removable racks carrying the enamely ware into and out of the furnace. v
In the accompanying drawings constituting a part hereof and in which like reference characters designate like parts, Fig. 1 is a sectional elevational View of an enameling furnace embodying the principles of this 'invention; Fig. 2 is a plan view of a charging fork used in connection with the operation of the furnace shown in Fig. l; Fig. 3 a cross sectional view taken along the line III--l III, Fig. '24; Fig. 4 a plan View `of a 'removable rack.; Fig. 5.a. longitudinal sectionalielevational viewofthe furnace shown in fF ig. l; 'and Figs. Gand 7 are respectively a plan and .section ofthe capping bars `utilized in adapting a standard furnace tothe use ofre` movable racks.
Referring to 1 of @the drawings the structure therein lillustrated comprises the sidewalls -1 and top 2 of a furnace provided with suitable heating relcrnents 3"a.nd having transverse beams t supported kon ledges of Hthe .furnace wall. Running longitudinalLy of the furnace chamber isa refractory pier f6 whichconstitutes afcentra'l support for the beams 4.' rThe beams 4 are provided with lpins which is .placed thereon by a suitable chargingffork suchas isshown in 2. l
The charging "fork comp rises 'a plurality of parallel spaced bars 8 having rprojecting ,pins 7 thereon similar to the pins shown in Fig. 'l and the bars 8 are-so spaced'that'they register with the spacesbetween thepins of the furnace so th "a.t when vthe charging 'forkfis projectedinto 'the furnace,theb ars 8 will lie between the `pins s7 and by subjectingthe-fork 7 which constitutethe supports lfor the ware toyertical movement to eitherraise or'lower .the `ware to be' heated onv tlre'pinsv V7', 'the fur.- n'ace'i's" charged or discharged asthe case 'be and the charging kfork 5visfwithdrawn.
'i Itl will Lb'eund'erstood*with Yreferenceto Fig. Y5 ithat ythe permanentrack enclosing the p in members 7 'is preferably made` of sectional members" to prevent ybuckling .and distortion ue -to' 'expansion and contraction effected The subject matter 'heretofore explained constitutes no part of the present invention since it is descriptive of a standard form of enameling furnace of the permanent rack rvtype which is, as previously explained, suitable for enameling large sheets or table topsv and the like. I y
My invention consists in capping the pins 7 of the permanent rack with suitable bars 10 (Figs. l and 5) to provide supports for a plurality of removable racks 11 (Figs. land 4) and further in providing similar capping bars for the charging fork of Fig. Q,whereby the racks are placed on the fork, loaded with lware to be enameled, and then charged into the furnace chamber where they arel supported on the capping bars 10.
Referring to Figs. 6 and 7 the. capping bars are of any suitable shape and provided with tapered openings 13 which need not necessarily project through the bars but are preferably extended through the entire bar section as shown 'in Fig. 7 ,to facilitateithe coring ofthe openings since the bars are preferably cast of suitable heat resisting alloy.-
A plurality of the bars 10 are arranged longi tudinally in the furnace in the vmanner shown in Figs. 1 and 5 and also transversely in Vspaced relation asfshown in Fig.1 toprovide i "end and central supports `forthe removable racks 11;v As shown in Fig. 3, tivo ysets of bars are longitudinally disposed in spaced relation on the charging forli so that When the latter is projected between' the pins 7 of thev permanent rack in the furnace7 the bars 10 'of theV forlrwill'lic between the capping bars of the furnace rack whereby the removable l'f racks11 maybe loweredjto andfromy the capping bars in the furnace.
The capping barsmay bereadily placed in VVthe furnaceby tongs and by virtueof their seats readilyl alignthemselves with' the pin lmembers 7, andthe bars are similarly placed on the charging fork `whereby the standard permanent type rack furnace is conveniently converted into the removable rack type structure, thus permitting thel use of the furnace for thefiring of small irregularly shaped arv-V ticles.` y A The advantages of such a combined permanent and removable' racktype furnace are readily apparentfrom afconsideration of the co'stof furnace structures which `makes it highly desirable to Iutilize'a single furnace forboth large and small articles.
A 4 The removable racks 11 shown in Figsv.;`
and 5 lare of a standard form'and comprise double rows of supporting pins Whichare integrallyformed lWith a supporting band or rim.l The racks are adapted to rest transversely of the bars on the charging fork in the order ofthe arran ement shown in Fig. 5 and, `when so assem ledon the fork, the Ware is laid on'the pins 7 after which the racks are bodily transferred to the vcapping the spirit of this invention.
tion with'a plurality of'longit'udinal sections provided With pins foi 'supporting' articles, of a plurality of capping bars havin 'seatsfor engagingsome of said pins, .said'j ars cornlpraising sectional members disposed'in 'long'itudinal alinement,` and in spacedjrj-relation transversely lof the 4furnace to. constitute vcen'- tral and end supports for rerriovable'rack 'i members.l t e v Intestimony 4my handlV whereof, have hereunto set ,f i
