= The, present invention relates toleer's, particularly for annealing ware of variable heights In annealing bottles, for exaniple, it is important that-"the annealing heat .Fbe controlled to insure adequate annealing of the lower portions of thebottles without -subs o jecting the upper portions to toomuch heat,

which may be sufiicient to cause deformation of the bottle necks where the heat aroundthe upper portion of the, bottle-is suflicient-to soften-the glass. t a

In some instances e'fiorts have been made to avoid undesirable neck softening by reducing the temperature in the upper, portion: of the leer. This reduction has generally been accompanied by a corresponding reduction of the heat in the lowerportion of the leer, as a resultof w-hich the l0Wer por-,

tions of the ware, particularly in'the case of relatively tall bottles, have -been insufliciently annealed. V V v Where the height of the 166i, nsid rs suflicient'to accommodate relativelyytall bottles,-a considerable amount, of heat -is wasted V in' the annealing of small, bottles lot a vrfe'W inches height.

Constructions have been proposed for regulating or controllingsthe annealing: heat to which the upperan'dlower portions of relatively tall b0ttles,;for example, areto be i subjected. Some ofthese constructions ll]:

- portion ofthe leer.

volve a relatively-I movable Y :ba'flie plate located Within theileerfbetween the ceiling and floor thereof, such platesbeing raised or lowered to acc'ommodate Ware of different heights. Such'bafile plates, however, are subject to the disadvantage I thatQ-heat is transferred to and through such plates and the'heated airrises past them into the upper It has also been proposed to raise and lower the ceiling of the leer with respect to the floor thereof, or with respect to an endless belt carrying the ware throughgthe leer, but theseconstructionsare, likewise disadadjusting the ceiling :otthe ,leer vertically, the thickness ,olfinsulation' of-the leer walls has been vaijiedg thus not only resulting a loss ofhe'at but introducing a variable fac- U tor inthe control ofthe proper annealingtemperatures- Another. objection to such constructions has been that, in accomplishing variability in height of'the leer for ware of" different heights, a considerable heat loss has resultedd'ue to leakage where-the parts annealing of ware I of different heights,

"whereby adequate annealing of: both the.

upper and lower portionsof ware, such as tall bottles, may be accomplished iwithout of the present danger of undue softeningof the bottle necks f or upper portions of the warei.

prising relatively movable upper andloWer sectlons 1n which these sections may be mov ablerelatively' without the occurrencelof any'variation in the wallfthickness or insu lati0n.- f 7 e V 1 A further object "of the invention. is to provide, in connection with this relative movement, means for insuring tightness of Q the relatively movable parts after their ad: justment, said means permitting relatively free movement of the leer sections when dey sired and providing a seal after vthe adjustment, resultingin a wall tightness comparableto that-0f known leers having relatively fixed or unchangeable interior height.

Referring in detail to; the drawmgs, the

leer here shown as embodying a preferredv form of the invention is provided witha stationary bottomconsisting of layers 11 and 12 of insulating material resting ion'a bottom plate 13 which, in turn, is supported by suitable framework 15. The bottom 13 is preferably providedwith side flanges 16" between which is received the lower insulat ing layer12. The flangedplates 18 receive between them the insulating layer 11, hold.

' in g layer, 12. p

plate 18 is. side plate 20 extending the length of the leer, 'eaohplate 20 supporting ingit in' fixed relation to the: lower 'insu'lat Supported upon each "flanged aware guide'22, for guiding ware carried longitudinally through the leerup'on an end- 1 less wire belt conveyor 24, idle rollers 25: being provided outside-of and below the bottom of the leer for the flower run of the conveyor. The upper run ofthe conveyor. is supported by a plurality of spaced rails 26 extending substantially-lengthwise of the leer and supported in fixed pos'itionthere in upon a plurality of firebricks 28, or other suitable supports. Above the bottom of the leer and below the rails 26 are-located a plurality of heating'elements 80,wh'ichare preferably composed of electrical resistance to facilitate their convenient control in groups. Theheatsupplied by these elements'passes upwardly in theleer through the interstices ofthe wire belt conveyor-for annealing. the ware carried thereby. p

- The stationary rails 26, upon which rides the upper run ofthe conveyor, instead of.

extending exactly parallelwith the length of the leer, preferablyextend at a slight anglethereto in order to distribute'wear on the lower face of the upper run of thebelt- F or example, the rails 26",fat the were entrance end of the 'leerpinayextend toward the right side ofthe leer and the rails at theware exit end of the leer may extend inwardly of the leer toward the same. side.

This construction not only distributes the e0 wear on the conveyor belt but also prevents the conveyor from. being biased toward either side asit travels-through theleer.

In iorder further tore'duce the wear upon the conveyorbelt, each rail 26 is preferably provided in its upper face with a plurality of holes or: depressions,preferably with flat bottoms, for the. insertion of lubricating plugs,. forexample, of compressed graphite or other lubricating material capable of withstanding relativelyhigh temperatures, such, for example,-as 18009 F.

The conveyor belt is: moved tl rough the leer by any suitable mechanism, which, for

;example,may include 1endYrollers and suit-. -able driving means such as a motor 36 through reduction gearing 38.1

The invention includes .an upper leer section, vertically movable w th respect to the "leer bottom, andthis upper movable section preferably includes atoplO and side walls 42, all carried within thesheet metal cover As indicated inFi ure 2the too of the leer is preferably provided withits thickest and most effect ve insulation at the ware enitrance end, hereinshown as being at the left. hand endas viewed in Figure 2, the thickness of p this insulation being reduced in stepstoward the ware exit end of the leer.

Theside walls 42 of the movable section may be, provided'with. insulation of unvarying thickness throughout theirlength, or

of varyingthickness' or effectiveness, if dcsired;

' The invention includes means for supporting and for raising and lowering the upper movable section and, as embodied in the present illustrated'form of the invention, an inverted channel iron e8, extends lengthwise of the leer along-the bottom of each side 1 wall 42,,being' secured thereto by vertically extending through-bolts 50 whose upper ends extend beyondthe leer-top and are suitably secured to carrying beams 52, one of which extends lengthwise of the leer'horizontally abovel'each side wall thereof. The beams 52,

at suitablefintervals therealong, carry fixed thereto=pu1leys 54. s

Cooperating with thepulleys on each side are cables 5 6, each. having one end fixed, as

at 58,'in the upper transverse supports 60 carried by the vertical members 62 of a 56 and'thereby" raise or lower the upper "movable'leer' section. The means for this purposeherein; illustrated includes a pair of chams 76' passing over su1table sprocket gears fixed on shaft 7 0 and'operativ'e'ly connected, through reduction gearing 80, to an actuating pulley 82 orsprocket wheel which may be operated conveniently by hand through the chain 86, or by other i's'liitable adjusted to provide for effective @annealingf of ware of predete mined, height, and, in the present embodiment,' flthisQmeans not only looks the movable sections to each other in fixed relation, but alsolacts' to sealthese sec 'tionsftogether. after their relativeadjust ment, thereby ellnllinating*heat losses which would otherwlseioccur and! also ns'nring against nndesired variation of the successively'predetermlned lower temperatures w thln ware .eXit end.
