Original No. 1,615,834, dated February 1, 1921, Serial Io. $0,950, am my 18, 1925. a lication mreissue fled November 25, 1927. Serial No. 235,716.
The invention relates to apparatus for producing a continuous sheet or ribbon continuously from a bod of molten glass. It has for its, primary ject the provision of improved means for accomplishing the function as above set forth and for producing glass of superior quality, which is perfectly,
Fig. .5 is a section on the VV of Fig. 2.
And Fig. 6 is a vertical sectionthrough a modification of theFig. 1 construction.
1 Referring to the drawings, '1 is the end ofa melting tank, preferably of the well-known regenerator type having at its end the forehearth or kiln 2 with a pair of cut 06 gates 3 and4, arranged as indicated inFig. 1. These gates are supported from above by means of the chains 5 and[6 carried by suitable overhead lifting means, not shown, the gate 3 being of refractory material, such as clay, and the gate 4 being of metal provided with-means whereby it may be cooled by a circulation of water. The 11 per side of the iorehearth 2 18 open and in t s open space is mounted a pair of forming or sizing rolls 7 and 8, such rolls a being journaled at their ends in the brldge 9, such bridge being movable into and out not shown, to which the bridgeis connected 1 by means of the chains 10. j p 7 Onthe outer side of the roll 8 1sa table or platen 11, preferably water cooled by means of a circulation therethrough. The glass sheet 12 passes over the table 11 and onto the apron 13, such apron bei pmvided with a series of watercooled ven rolls 14 to 24. The apron rests at this left of position by means of an overhead crane,
tensio right hand end is pivoted for swinging movement around the axle 26 of the roll 24,
so thatwhen desired, the apron may be swung up-to a vertical position from the horizontal position shown. Mounted above the apron is a. portable cover 27 supported from above by means of the chain 28 preferably carried upon a suitable crane whereby the cover may be moved laterally after it 15 lifted from the position shown. A plurality of burner pipes 29, 30 and 31 are ample ed for maintainlng the temperature of the glass in its passage to the leer. Beneath the apron 1s a portable bottom member 32 supported upon thetruck 33 mounted on the track 34. The member 32 assists in maintaining temperature conditions constant in the space surrounding the glass thereabove. The truck permits the member 32 to be removed to one side when the apron is removed in order to give more ready access tothe front end of the furnace for replacements or repairs.
From the apron,the glass passes into the end of the leer 35, which is of the roller type employing the series of rolls 36, 37, 38, etc.
The leer rolls are driven by means of a chain 39 passin around suitable sprockets on the ends of t e roll shafts. The and roll 24 of the series of apron rolls is driven from the endleer roll 36 by means of a short chain 40, passing around suitable sprockets on the ends of the two rolls The other apron rolls are driven by means of the chain 41 passing around a sprocket on the end of the roll 26 and over' the tops of other sprockets carried by the ends of the apron rolls. -An idler roll 42 is provided as a takep for maintaining the chain 41 in v The endsof the rolls 7 and 8 are set down into theside walls of the forehearth 2, as 1 indicated at 43 in Fig. 4, and the triangular ace in'the wall between the rolls is prefer- :bly closed by means of the hollow metal circ' heated froni a burnen pipe 46 leading .in at one end, the gases of combustion allowed to discharge through perforations 47 at the other end. The heating of the member tends to give tla: edge of the sheet which on the shafts to which the tumbler shafts 'continuously,
are connected; The ends of the bridge are so ported by the standards 48 (Fig. 2 to w ichsuchendsaresecuredbymeanso the bolts 48".
In operation the rolls 7 and 8 are rotated drawing up from the body of molten lass the sheet 12' which p over 'the tab e 11 and the apron 13 to the leer.- Thecontact of the glass with the rolls 7 and a Band with the table 11 causes it to set-to suchan extent that it will not sag to any substanfill (hgl'BO when it p w the apron 13 and from this point on, any unevenness in the glass is flattened out as the sheet progressesover'the rollers and the leer. The glass is annealed in the leer and cut ofi at the far end thereof, after which it s ground and polished in the usual way on circular tables or in a straight away surfacing operation. The rolls 7 and 8 size the sheet to substantially its final thickness, the surface formed being relatively smooth as compared with-plate glass casein the usual way on tables, but uires grindi' and polishing due to the ii iarring of tli bfi Fig. 6 i ustrates a-modification, which differs from that of Fig. 1 only in that the sheet 12 as formed between the sizing .8 pa directly onto the water cooled rolls 54 of the apron, instead of passing first onto a table or platen, such as thetable 11 in Fig. 1. This arrangement me be if the glass sheet as itis formed y the rolls 7 and 8 l8 snificiently chilled so that it will "not sag to any substantial extent in passing to the end roll of the apron and over the succeeding rolls of the apron.
What I claim is:
1; In combination,
y and having the rh'ons of their peripheries casing 53 comover the rollers of rolls 7 and,
so as to of said ,rolls for carrying away the glass which is formed.
2. In combination, a glass tank containing 'which the ends of the rols are journaled,
means for supporting the bridge for vertical movement, an a glass receiving bed extendlaterally from the side of one of said :is for carrying away the glass wh ch is formed.
3.. In combination, a glass tank contaming a body of molten g1 and having a slot in its upper wall, a pair 0 horizontaldriven and cooled sizing rolls seated in and slot,
and constituting a closure therefor and having the lower portions of their peripher ies immersed in said body of glass, and a glass receiving bed extendin laterally from the side of one of said re s for earrymg away the glass which isformed.
4. In combination, a glass tank containing a body of molten glass, and having a slot in having the lower portions of their pe'ripherits upper wall, a pair of horizontal vdriven ies immersed in said body of glass, 9. bridge in which the ends of the rolls are journaled,
