I claim: v

1. In the manufacture of wire glass, the steps consisting of drawing a laver portion of glass upwardly from a molten bat-h, drawing another layer portion upwardly separate from the first layer portion, deflecting one layer portion, prior to uniting it with the other, feeding wire mesh between the glass layers, uniting the layers, and drawing the wire glass in a horizontal direction in a continuous manner. 1

2. In the manufacture of glass, the. steps consisting of drawing a layer portion of glass upwardly from molten bath, drawing upwardly another layer portion of glass separate from the first named portion, deflecting one layer portion separately from the other, and then bringingthe layers into contact, and drawing them in a generally horizontal direction in a continuous manner.

3. In the manufacture of wire glass, the' steps consistin of continuously directing a plurality of sheets upwardly in a general vertical direction from a bath of glass, bending the sheets into another direction at the place where one of said sheets first changes its general vertical direction, and continuously embedding the wire mesh between the sheets at said place, substantially as described.

4. In the manufacture of wire glass, the steps consisting of drawin a plurality of sheets in. a'general vertical irection, reheating the adjacent surfaces of the sheets, embedding wire mesh between them, and bending the combined layers over a bending device, substantially as described.

5. Inthe manufacture of wire glass, the stepsconsisting of drawing a plurality of sheets in a general vertical direction, reheating the adjacent surfaces of the. sheets, embedding wire mesh between them, bending the combined layers over a bending device, and fire polishing thesurface of the wire glass as it is formed, substantially as de; scribed.

6. In the-manufacture of wire glass, the method which consists in drawing a plurality of sheets upwardly in a eneral verass, unrolling a'roll. of wire .mesh at a level above the bath, and embedding said wire mesh between said sheets, substantially as described.

7. In the manufactureof wire glass, the method consisting in drawing a plurality of sheets upwardly in a general vertical direc tion from a bath of molten .'glass, bending them into a different direction, unrolling a;

,ten glass roller means for deflecti :flier into roll of wire mesh at a level above the bath andfeeding the wire mesh between the sheets, substantially as described.

8, In the manufacture of wire glass, the

steps consisting of drawing a layer portion of glass upwardly from a molten bath, drawing upwardly another layer portion'of glass separately from the first named ,portion, feeding wire meshbetween the glass layer portions, changing the direction of travel of the wire mesh 'rior-toJunitin'g 'the layers and the mesh, and thereafter uniting the three layers.

9. In the manufacture of wire glass, the steps consisting of drawing a layer portion of glass upwardly from the molten bath, drawing upwardl another layer portion of glass separately rom the first named portion, feeding wire mesh into contact with the inner face of one glass layer, and thereafter uniting the three layers and carrying them in "a generally horizontal direction. 7

10. In the manufacture of sheet glass, the steps consisting of drawing a sheet vertically from a bath of molten glass, acting upon the outer portions of the rising sheet with edge rollers while leaving its intermediate portion free, and deflecting the sheet'into an other path;at an angle to the vertical and horizontal after it asses the edge rollers.

11. In the manu acture of sheet glass, the steps consisting of drawing a sheet vertically' from a bath of molten'glass, acting. upon the outer portions of the rising sheet with edge rollers while leavin its ntermediate portion free, deflecting t e sheet into another path atan angle to the vertical and horizontal after it passes the edge rollers, and passing it over a roller engaging the intermediate portion of the sheet.

12. I In themanufacture of sheet glass,'the

1y from a and then deflecting it into a path'at an angle to both the vertical and the horizontal.

13. In glass-making apparatus, means for drawin a plurality of separate and disconnected at glass layers upwardly from molone of said layers independently of the another path, and means for bringing the two layers into contact and carrying them horizontally in a continuous manner.

14. In glass-making apparatus, means for drawin a plurality of separate and disconnected flat glam layers upwardly from molten glass,- roller means for deflecting one of said layers independently of the'other-into another path, and roller means-arranged to bend the other glasslayer in a horizontal direction to bringv the two layers into contact glass bath, engaging it by opposed rolling surfaces while traveling vertically,

and disconnected glass layers upwardly from wire mesh between them and carrythe wire glass in a horizontal direction.

16. In the manufacture of sheet glass, the steps consisting of. drawing a sheet verticallylfrom a glass bath, engaging it by opposed ro in then eflecting it into a tpath at an angle to both the vertical and e horizontal, and passing it over another deflecting roll which It acts to flatten the sheet, I

17. In the method of making wireglass, the steps consisting of continuously feeding molten glass to a heated receptacle wherein the glass rests as a liquidbath, continuously withdrawing from saidreceptacle. two spaced apart ribbons ofIglass while maintaining t e width thereof, brin 'ng the ribbons together at a point space apart from the receptacle, and-supplymg-wire mesh be- 2 tween the ribbons from a source lying within the-space defined b the receptacle and the ribbons extending t erefrom. '1

18. In the method of making wire glass, the steps consistin of continuously feedin'g 80 molten glass to" a eated receptacle wherein the glass rests as a liquid bath, continuously withdrawing from said receptacle two spaced apart ribbons of glass while maintaining the width thereof, brggin g the rib- 85 bons together at a point spa apart from the receptacle, and supplying wire mesh between'the ribbons from a source lying within the space defined ribbons extending refrom, the wire fabric 40 being supplied to the glass adjacent the point where the glass ribbons are brought together.

f a 19.. In the method. of making wire glass, the steps consisting of continuously feedin'g' molten glass to a heated receptacle wherein the glass rests as a liquid bath, continuously withdrawing, from 'said rece tacle two spaced apart ribbons (if glass whi e maintainsurfaces while travellng vertically, Y
