Referring non' to the accompanying drawvings in which like numerals and letters efrcferenc'e indicate like parts in all of the figures, A designates the. bell fiar of an air' exhausting apparatus which' includes the top B, 4the bottom 'C and 'the intermediate The top', bottom andintermediate members B, C and A are yheld together 'i bolts af which are inthe.'

-"sulaled from the iop and bottom by the in- .siilating' bushing'a; l as clearly shown' 1n Fig. -1. -To insure an hernieiieal joint between parts B. and C and the transparent fseetio'n A, I provide the cup shaped portions (z. v1n which the packing rings a? are held'. 1

' The top B is apertured as atA o to'receive thevinner receptacle E which has an annular flange E' by means of which it is secured to the top l. Fasteiied to the top inist-rows ,ffgfor otherii'ise, 4is a 'second receptacle F which surrounds and is preferably arranged conventi-wally with the receptacle E, ,which 4receptacles,ll Vand l" have their outlet :ipertures or mouths in the saine,verticalulinement for apurpose presently understood.

-K designates a. culibrating mouth piece lit-ted'oi'er one or both ofthereceptacles E .tlicl'niouth of receptacle 1") ltorwhich itis sccured by the split ring K and the springs K which-take' in thc depressions f of thofrecepa' 'g2 .for admitting the material to the receptacleA Fanil this pipe G isprovided .ijitli a funnel shaped receptacle G A.for a purpose readily. understood;- .Gl designates a 'pipe Fig. 7, is a n Aand l (on the drawings-it. is shown only over coinmgnicating with the receptacle F, conl the dust from entering the ipe a and eventrolled by a cut-ofi valve G i'or the admission of either compressed air or steam for driving the semi-liquid material out of thc :receptacle F durinc' the process of squirting the iillet :is will be Ihereinafter' more fully explained.

'lhe receptacle E is closed by a top or cap plate g which is secured thereto bythe screws e, which screws also serve tq'connect tlic receptacle E to the top B. An inlet pipe gl2 havin the cut-oil' valve g coinrilunicat-es with tlie receptacle E through an aperture in the late g and by means of which the Inaterial is fed to the receptacle E.

g designates a pi ie communicating with the receptacle E an controlled by a cut-mi' valve g1 by means of which compressed air or steam is admitted to receptacle E to force its contents out during the process of squirtin the fillet.

assin through an insulating gland n2 in rzte g is the tubular rod N through which the needle red n asses. A terminal c is connected to the ro N as shown in Fig. 1 by means of which 'any suitable source of electric currentsupply may be brought into electrical connection therewith. The top B is apertured to receive the pipe connection' a from any suitable air exhaust'- ing or rarefying apparatus, not shown, and the communication with such apparatus is revulated by the valve au in the pipe a.

. designates an incandescent lamp held within the bell 'ar A for lighting up the inte- .rior thereof an this lamp connects with any suitable outside source of current supply in the usual manner.

M represents a fillet intercepter and sampler consisting of the receiver m, the connecting tube and holder m', the hook m which passes through the tube 1n and has its outer end provided with a stopper inserted into a mouth piece ms for hermetically closing the tube-m. The tube m passes hei;-

`meticslly through the insulating stuiling m to the inside of the bell jar A. By means of this sam ler M which is.movable toward and from t ie iillet, samples of the s uirted fillet ma be taken at various times an withdrawn om the apparatusfor testing or other purposes.

- O represents an ejector or other dust sprinkler for ejectingv into the belljar inte nor at a suitable elevation graphite or other functionally similar dust for coating and d ing' the squirted illet, which effect it shou d be understood, is aided by the exhausting of the bell jarwhich exhausti action also aids the dust to reach the .fi et L as it is squirted, so that it may settle thereon and coat the same.

The mouth of the pipe which connects with the air exhausting apparatus may be covered with a cloth diaphragm c to prevent tually reaching the pump. he excess of dust in the bell jar is collected by the dust collector I diagrammuticiilly shown in Fig. 1.

a" indicates :in iiir admitting pi e communicat-ing with the bell jar A and w iicli is controllcd by a valve as, as clearly shown in Fig. 1.

lt represents a guide for the fillet core or filament., which hns a loop r for surrounding the fillet between the inout-h K of the receptacles and the coiler apparatus hereinafter side the bell jar A and hei-metically closed with respect to the saine. This vessel, as

shown in the drawings, forms a part ofthe sup orting base of the coiler mechanism hereina ter more fully explained and this vessel H has for its object to receive steam therein throughthc pipe als which passes through the in ating ushing a" of the bottom'C and th. steam supply to the vessel li is regu-v lated by the valve a as shown. This vessel f H serves as a heater to radiate heat into the s ace into which the fillet is being squirted.

i bile I have shown this heater as a steamV heater, yet I desire it understood that the same may be used to burn charcoal therein,

for the production of the heat.

While I have shown the vessel H asia art of the base of the coiler mechanism, yet de sire it understood that the heat-producing' vessel may be an independent vessel and iocated anywhere within the bell-jar, without departing from my invention. Y

he mouth piece K before referred to is so designed as to give the fillet the desired cross4 sectional area and is made up of'essentially two parts, the mouth piecelmember and a split ring K' and individual narrow springs K with projections for entering the indentations fof the receptacles.

It should be understood however, 'that I do not limit myself to the exact method of attachingdthese calibrating mouth piecesas any suita le means ma l be used, which will perform the desired unc-- tion and I also desire it understood that one or more of the vessels may be provided with these calibrat` mouth pieces depending upon the condition of the fillet. I also dosire it understood that I do not limit'mynalf to the use of the exact form of'calibrating,

mouth pieces, as any other suitable' calibrating devices such for instance, as the smaller ends of the tentaclesof the lobster, may

used. D l

From the foregoing it will be seen that the axial center of the stub-shaft 2h dos not coincide with the center of the gear 4 and therefore when the internal gear housing is revolving the center of the shaft 2h will also describe a circle. As the local position of the centers of the pinions or gears 2f"1d with respect to each other are constant the gears will commence revolving as soon as the gear 4 comes into contact with the rack portion 5 and rolls on it. Supposing the number of teeth in the gear 2*- to be equal to the number of teeth in the rack section 5, the gear 2c and eoiling vessel 7 will make one full revolution around the axial line of the stub shaft 2" tbereb r forming the small circular loop in the ilament around the conically shaped members' 1a. Continuing the rotationot' thegear 4Q over the are or angle B (see Fig. 6) the gear 2" will be' then without motion and the coiling vessel will rotate around its center V, Fig. 4, thereby forming the oval shape part of the filament over the other core member 1'l of the rece tacle. During this period of coiling the ibut plate 2 and the coiling vessel l are held in proper position with res ect to the housing 4' b the locking stu or lug .8 s ring presse to its locking position. To iminis l tbe friction in the gears and other parts, the whole space between the housing` 4 and the base 3 is filled with any suitable lubricating material. Y When a small receptacle rotatable on a central'vertical axis without the coiler mechanism, is used, it is only necessary to manipulate the lille-t by means of the guide R.

While I have shown the coiler mechanism as any automatically operating mechanism yet a simple rotary receptacle may be used particularly when it is desired to merely form a circular or hemispherical iillet or one of a spiral form or any other mechanisms devisa le in mechanical art mav be used for similarly moving the coiler. he receptacle or coiler it will be noticed is provided with a groove or grooves d into which the issuingtillet i is caused to drop. The coiler mechanism is so formed and regulated as to move only with sufficient speed to take up the illet as it is scuirted into the receptacle 1, the speed .at w lich the fillet is squirted being regulated by regulating the pressure in the receptacles E and F for forcing the materials therein connoticed that the mouth of the groove i? is tained out through the mouth of the said receptacles.

By reference to the drawings it will be wider or funnel shape to compensate for discrepancies in the mutual positions and speeds ofoperation of the said parts.l The ceiling mec xanism perfomis'thevfunction 1st. by proyiding means for receiving the squirted ilament at the same rate ot length perstated time as it is ejected from themouth of the recepta cle, such rate of ejection being`r regulated either 'by regulating the pressure of the air before the materials in the receptacles or by regulating the revolving speed or motion of the coiler mechanism. 2nd, The coiler mechanism lserves to form the llet into the individual shape desired.

brom the foregoing'it is apparent that for diflerent forms or shapes of glowers not only dillerent tillet receptacles are requiredl but the position of the receptacles can be varied with respect to the supporting parts being either eccentrical or concentrical, depending on the shape or form of iilament desired.

One result obtained by the coiler mechanism is to hold both of the coils and the uniformly cut parts thereof, while the same are being treated,-hardened or evenzually carbonized, until they are ready to be assembled in the complete lamp. To permit of ready access to the coiler fillet the envelop 1b may be made removable and is preferably composed of glass to permit inspection of the coiled material during the operation of the apparatus and I may omit to use this envelop lJ if desired when the ceiling action is such that it can be dispensed with. Again when this envelop 1b lis not used, the coiled fillet is under the drying influence of raretied air as before referred to and may be dust coated by means of the dust ejector 0.

When the envelop 1b is used I may till the groove d with any suit-able liquid which will preserve or serve a useful function with respect to the fillet, provisionbeing made for the over-flow of such liquid in the hollow core members 1-l I may construct the coiler of any suitable .mechanism now known in the art to allow for passing current through the iilament.

While I have shown one of the receptacles E as loca-ted within the other receptacle l1", I do not desire it understood that such is the only position they may assume vas both receptacles ma be held entirely without the bell jar H so ong as their ezzit ends are within the bell jar and so long as their exit ends are practically in the same aline-ment so that the two fillets issuing simultaneously may be twirled or twisted to form a .single cord, thread or fillet and as such be guided into the coiler mechanism receptacle. Again while I have shown but two rece tacles yet I desire it understood there may more or less, depending on the number of strata, of which it is desired to construct luminants.

In Fig. 7, I have shown a modified form of my invention in which I suspend a bobblll S upon which is wound a fine metallic wire the end of which, passing throng-h the squirting mouths, is secured to the receptacle so that in the formation of the fillet the same will be 2.
