Be it. known that I. Cmnm'cn P. BYRXES,
' of Sewickley, Alleghenyrounty, Pennsylis al view similar to Fig. 3
vania, have invented a new and useful Improrement in Drawing Glass. of which the following is a full, clear. and exact description, reference being had to the accompanying drawings. forming part of this specication,'in which- Figure l is a sectional side elevation showing one ferm of apparatus for carrying out my invention inthe manufacture of wire glass; Fig. 2 is a sectional front elevation atl-right angles to Fig. l; Fig. 3 is a View similar to Fig. l Showing another and (pre- `fe'rred' larrangement of apparatus; Fig. 4e showin-g .thea plying of wire fabric to a sirigle sheet or plate; Fig. 5 is a detail view showing anpther means foruniting sheets; and'Fig. 6
'1s a cross-sectional view showing the glass lsheets integrally `iomed at their ,edges prior to forcing them against t-he wire fabric; Fig. 7 is a side elevationshowing cam mechanism; and Fig.8 is a vertical section showing a modification.
My1 invention relates to the drawing of glass, and particularly-to the forming of` sheets or plates, and/ the making of wire glass.
The invention consists in drawing asheet or plate of glass from a bath of glass), and
l at the same time applyinga wire structure or y fabric thereto,
during the drawing operation.
It further consists in drawing two or more:
jsheets of glass and combining. therewith combined sheets' or tending lengthwise for` the vthe entire length of the pot.
during drawing.` a wire fabric of greater width lthan' the sheet. i
Itfurther consists in fire-polishing the plates during drawing, and in {othe'r details and steps hereinafter described .and claimed.
In the drawings, referring to Figs. l and 59,2, 2 represents. a pot arranged to contain moltenigl'ass, which may be of elliptical or rectangular forni.f and is provided with a refractory, partition, nozzle l'or well 3 eX- major part of lSpecification of Letters Patent.
In the form Patented June 8, 1915.
-able standards 6. The glass-holding pot is preferably supported in a suitable furnace which may be heated 1n any desirable manner, as by gas Jets 4. The drawlng frame S is preferably provided with two parallel baits 9. '9. which are adapted to enter the glass bath on either side of the central partition. It is also preferably` provided ,with
` central means shown at 10 for securing the upper end of the. wire fabric l thereto. A drawing chamber 11 preferably' surrounds the space abovefthe pot for a considerable -hei ght, in order to prevent too sudden cooling ofthe glass. TNithin the lower part of this drawing chamber I place a pair of pressing rollers 12. l2 which are preferably hollow and provided with hollow trunnions which are. mounted in sliding bearings. These bearings may move within suitable slots 13Min the sides of the chamber, so that the rollers may be moved back during the beginning of the operation. The rollers may be kept at any desired temperature by a heating or cooling fluid circulated through thennby iexible'pipes 12. The rollers may be forced forward and held by cams or any suitable devices. and may be covered with lasbestos or similar material.
In Fig.- T I show a cam having a grooved track acting on bearing lugs on the bars Q3 and arranged to simultaneously force the rollers inwardly against the sheet being drawn. l Y
In beginning the operation of making wire glass the baits are lowered into the bath in the usual manner, and are then drawn upwardlv The glass may be chilled or set at the ,drawing pointby movable water-cooled chilling bars ll, on one or both sides of the sheets., if desirable. After the two glass sheets being drawn have been lifted above the compressing rollers l2 I force in these rollers so as to unite the plastic glasslsheets upon and around the wire fabric. The pressure should be suicient to embed the wirev or unite the plates in the meshes` and make the three parts into-a glass plate with the fabric embedded therein. 1l-he two sheets or 15 give the glass able; toward and'froln each other within' the 'i 50 of sind therethrough plates mayabe drawn' of the thickness,
continues as long as desired, when the lower end may be severed from the bath by shears, by flame, er' in any other'desirable manner. The glass may be gur'ed, or a lpattern or -10 prism shape given thereto on one side if v Mdesiredr by using lanotherfpair of 'rollers l5 aboveAthe compressing rollers y One of these rollers l5 has a figured or patterned surface 'corresponding to that which it is desired to `These rollers are also movn '.chamberL l It will be noticed by reference to Fig. 2 that the glass sheets whichfare drawn are of less width than the width of the wire fabric'.`
'This is preferable since it avoids thev necessity for breaking 'off the side portions of the glass to expose the fabric for securing in the ufacture of thick sheet glass.
draw two sheets of-plates by apparatus simi- 90 sashor frame.` I may, however; draw the 25 glass 'sheets as wide or wider thanvthe wire fabric; 'and I may draw the sheets withintegral.' joining portions at 'the ends as shownin Fig. 6, the sheetsnthen forming the sides of' an 'inclosed article.-
InA usome cases the compressing` rollers may be withdrawn-after they have acted upon the first portion ofthe sheets, as the inclination of the draw 'will pull the two plastic glass sheets together, and tend to, unite them on the wire fabric.A
each other. v v
In order to 'avoid themoving iof the line j of draw from the surface of the bath toward 7,40.. the slotted partition, which' is liable to take place in the' vfirst form, I preferably use separating means; such as\ the rollers 16 shown in Fig. 3,- -betweenthesheets 'llhese rollers form guides whichhold the sheets 4as they are formed .at a certain distance apart froingeach other, the sheets being deflected to I4andy betweenv the compressing rollers l12"? as in the first form. @The rollers -16 may be` hollowI and cooled or .heated fby 4al circulation The compressing rollers and the -separatf ingV rollersmaybe faced 'with asbestos to `prevent injury totheglass, but as they are liable f to ,injure the surface ofthe] sheets 5 5 during compression -and forcing. togretherwA Aupon the fabric, Ieptreferably fire polish-the combined plate duringCC its drawing, and while still. in a plastic' condition. A For .this purpose I showi'the gas burners '17 a row of which or a wide thin burner Amay extend within the drawing chamber 11a on `both a sides of. the plate? A highly polished sheet will/thus be obtained which willa-void the necessity. for grinding and polishing, where t? f-Wigre rlaterlassds desiree.
- plastic, thus making a thick ,n iay then 'be drawn upward and fire polished 95 invention, I preferably employ a ric 4in which thel cross wires are welded .to The sheets ymay be` draw-n together by lmoving the baits toward In Figml I show form of' apparatus where a single plate lor sheet of glass is drawn in the` ordinary'manner and the wire fabric-1s forced in through one face thereof.,
.In this form lower rollers18 Jand 19l are 70 used: 'the' roller 19 being preferably 'eircomferentially grooved or corrugated, sofas/ to force into the plastic plate the'wire fabric't which is drawn from the reel 5b through the slot 2O in the sideY of the 'drawing chamber` ,11b- The upper plain compressing rollers 21, 21 then close the glass over thefabric and smooth the' face ofthe sheet. In this operation 'the fabric is therefore forced into v the plastic p ate as it is drawn, to any desirable distance, and the face of the plate is then rolled and smoothed down. IThisl species, as well as the article produced by Vrny'iriyentio'nf,arel reserved ,for separate applications, not being covered in this applica# 85 tion. I f I The process of 'drawing the two slfeets and uniting them. is also' applicable vfor the man- Thus I may lar to that of Fig.A 3, except that the, slotted partitionin the pot is done away with and the two sheets are.`forced together` while,
plate, which if desired while still plastic.
In forming wire glassaccordin `to my,A
ire-fabthe strand `wires at the crossing points. This. welded fabric will reduce the strain on the 'glass during expansion and conraction of the fabric. andgive less liability Q 'to cracking and 'breaking An integral ex' f' panded sheet metal fabric may also be usedl 1.05
Instead of using rollers to unite the sheets .I may use other means, thusv in Fig. .5 I
show `the yuse ofthin widejetspfgaseous Huid, such as air te force the sheets together Instead of Ad ecting above the guide rolls. v
botlrsheets into a plane intermediate of the two points of drawing, I may deflect one sheet only, this sheet together' with the" I A.

Many variations may be made in the form of the apparatus, as well asin the process,
