Inthe manufacture ofsheetglass by the continuous process,-the newly formed plastic sheet, after leaving the forming rolls, passes over an apron en route to the leer.
5 After being formed the sheet rests on the lower roll for a certain predetermined are of rotation and then encountersthe nose of the aproin which guidesthe sheet onto the apron. In order to "properly control the cooling 1() and chilling of the new sheet,'it is advisable to be able to regulate the duration of contact of sheet and roll, and in order to do this the apron is adjustable as to position.
The object of this invention is toprovide devices whereby the position of the apron nose may be adjusted by a single simple operation, and without changing the distance or gap between roll and apron nose.
Further and other objects and advantages will be apparent from the'specifications and claims, and. from the drawings which show by illustration what 1s considered the preferred enibodnnent of the lnventlon.
Fig.1 is a side elevation of one inodifica .25 tion of the invention.
Fig. 2 is aside elevation of another modification of the invention in which not only the nose of the apron, but the entiresurface of the apron adjacent theroll, iskept at a fixed distance from the roll in all positions of adjustment.
Fig. 3 is a section on the line 33 of Fig. 2 showing details of the adjusting device.
Referring to Fig. 1, molten metal flows from the right between upper and lower rolls 10 and 12, to emerge as sheet 14. The sheet rests on: roller '12 until it encounters nose 16 oi the apronlS, whereuponthe sheet passes over the top of the apron en route to the leer. The apron is built in sections rigidly mounted on bar 20 which is provided at its lower end with rollers 22 resting on a plate 24. The
upper end of the apron is provided with ln'a-ckets 26 through which passes a trunnion rod 28, extending from side to' side of the apron. Rod 28 passes through a curved slot 30 in a vertical plate 32 rigidly mounted at each side of the apron. Plates 32 may be held at the desired height by means: of bolts '34; passing through selected holes 36in the was. seiri i are. 364,753.

Except at the lowest position of the apron there is a gap between the low end of upper section and the high end of the second section. If this gap becomes extreme, an air cooled pipe 76 is placed as shown in Fig. 2 to help carry the sheet over the gap.
It is to be understood that the invention is not limited to the specific embodiment and construction herein described but may be used in other ways without departure from its spirit as defined by the following claims.
We claim 1. In apparatus for making sheet glass, in combination, upper and lower rolls adapted to form a glass sheet, an apron having a nose adjacent said lower roll and adapted to conduct the sheet away from said roll, and means for adjusting the nose of said apron vertically while maintaining said nose at a constant distance :trom said roll, said adjusting means comprising a member fixed on said apron and devices constraining said member to follow a fixed path.
2. In apparatus for making sheet glass, in combination, upper and lower rolls adapted to term a glass sheet, an apron having a nose 'acent said lower roll and adapted to coni. the sheet away from said roll, and means for adjusting the nose of said apron vertically while maintaining said nose at a con stant distance from said roll, said adjusting means comprising a fixed guide, member which constrains the apron to move in a pre determined path. 7
3. in apparatus for forming sheet glass, in combination, an upper roll, a lower roll, an apron having a nose adjacent said lower roll, a selt-i-iligniug nut, a screw threaded through said nut and adapted to adjust-said apron vertically when said nut is turned; and guiding devices operative when said apron is ad-- just-ed for maintaining the distance between said apron nose and said lower roll.
In apparatus for forming sheet glass, in combination, an upper roll, a lower roll, an apron having an end adjacent said lower roll, a self-aligning nut, a screw threaded through.
' said. nut and adapted to adjust said apron vertically when said nut isturned; and guiding devices operative when said apron is adjusted "for maintaining the distance between the end of said apron and said lower roll.
5. In apparatus for forming sheet glass, in V 5 v lower roll, and means operable to ad ust said section, means for adjusting said upper sec' tion circumterentially of said roll, a horizontal guide, and a hinge between said upper section and the lower portion of said apron whereby saidlower portion may constantly rest on said guide in any position of adjustment of said upper section.
in testimony whereof we hereto altix oui signatures.
