Definitions

  • xBri'efly statedythe invention consists in-theuse of arelativ'ely thin f rubber sheetwhich isplaced over the sheetsto be composited preliminary to the step of exhausting the air from between the sheets and 30 preliminary to applying the compositing pressure.
  • This additional sheet protects the diaphragm from cutting and wearingwhere it engages the corners of; the upper glass sheet of the series, and thus increases the life of [such dia- 135, phragm several times over.
  • its use also permits'of a much more complete exhaustion of the air from betweenrthe sheets, so that air pockets injthe composited plates are avoided and thequality'of the prod- 4Q uct improved.
  • FIG. 1 is a vertical section through the apparatus inopen position.
  • Fig. 2 is a similar 7 view on an enlarged scale but' with the lid of the 1 A5; apparatus closed.
  • 1 is the platen of a press similar to that shown in my application heretofore referred to;
  • This platen constitutes the upper wall of the chamber 2for the fluid which 5.50.: heats the platen.
  • the fiuid' is appliedfthrough the connections 3, 4 and 5 and may be steam ora liquid heated 'toa temperature sufficient for the purpose;
  • the upper surface of. the platen is pro--.
  • the platen'l- is. mounted in asuitable hollow framework'8 closed on the lower side by theplate'9.- i
  • the cover of the-device comprisesaplatelfl hingedto one of the members; 8, as indicated at 11, and provided with a latch bar 12 by means of which the lid may be locked in' closed'position,
  • the bar 12 may. be moved gbeneath Q5;
  • the set of sheets to be composited comprises a pair of glass sheets 19, 19 and an interposed sheet 2fl'of'pyroxylin 7Q plastic, the opposing surfaces of the s heetsbeing provided with a suitable cement for sticking them together upon -the application ofheat and pres'sureas iswell known in the art.
  • Interposed between- ;the -bottomsheet of glass 19 and the 8G platen 1 is a sheet of woven .metaljscreenf21',
  • a rubbersheet 22 which is relativelythin as compared to the diaphragm 14. This sheet isvery light and may be removed when the cover is raised, but is clamped in position by the cover 95 when the cover is closed, as indicatedin Fig.2. Before lowering the cover to closed position, air
  • the sheets to be jcomposited being heated during this period from the platen v1 which is in turn heated by the steam or hot liquid which is circulated through the chamber 2.
  • the, sheet 22 performs the further functionof giving the diaphragm protection from. the heat of the platen 1 which protection is another factor tending to increasethe life of the diaphragm.
  • the use of the sheet-22 alsopermits the operatorto see after the vacuum' is put on whether or not the plates'are. laid up properly and whether asatisfactory vacuum is applied before the lid is closed: Without this sheet, these conditions'would be obscured after the .:'closure of. the. lid, and the results secured correspondinge.
  • Apparatus formaking composite glass comprising a metal platen for supporting the sheets to be composited,-means for heating the platen, a movable metal cover fitting over the platen and provided on its inner side with a flexible diaphragm, a flexible sheet impervious to air fitting removabl y over the sheets to be: composited. which are supported on theplaten, means for exhausting .the air from the space between the open position, and means for supplying fluid under pressure behind the diaphragm.

  • a movablemetal cover fitting over the platen and provided on: itsinner side. with ,a:rubber.;dia
  • a method of making composite. glass which comprises superposing ,a. plurality of sheetsof glass, interposing a reinforcing material between the sheets which, is; adapted to ,be adhesively united thereto, disposing a flat sheet of flexible material impervious to air over one side of the glass, creating.a vacuum in the-space coveredby the material andapplying a compacting pressure 129 JAMES H.
