Abstract

A method of glazing a sash is disclosed. The method begins by placing a sash on a glazing table, wherein the sash defines an opening therein and has a glazing leg extending into the opening in the sash. At least two positioner assemblies are actuated, each positioner assembly having a position member defining a distal end. Each position member is selectively slidable between a stored position and an extended position. When the positioner assemblies are actuated, each position member is moved into the extended position such that the distal end of the positioner member contacts the glazing leg of the sash. A viewing element is then inserted into the sash opening and into abutting contact with portions of the positioner members so as to create a gap between an interior surface of the sash and an outer edge of the viewing element. Once the viewing element is positioned, the positioner members are retracted. Next, a back bedding glazing compound applicator assembly is actuated to move from a stored position to a dispensing position. The back bedding glazing compound applicator includes a nozzle head that is configured to fit within the gap between the interior surface of the sash and the outer edge of the viewing element when in the dispensing position. Once positioned, back bedding glazing compound is dispensed between the glazing leg and the viewing element. Once dispensing is complete, the back bedding glazing compound applicator assembly is retracted.

Claims

1. A method of glazing a sash, comprising:

placing a sash on a glazing table, wherein the sash defines an opening therein, a glazing leg extending into the opening in the sash;

actuating at least two positioner assemblies, each positioner assembly having a position member defining a distal end, and wherein each position member is selectively slidable between a stored position and an extended position;

wherein the positioner assemblies are actuated such that each position member is moved into the extended position such that the distal end of the positioner member contacts the glazing leg of the sash;

inserting a viewing element into the sash opening and abutting the viewing element against portions of the positioner members so as to create a gap between an interior surface of the sash and an outer edge of the viewing element;

retracting the positioner members;

actuating a back bedding glazing compound applicator assembly to move from a stored position to a dispensing position, wherein the back bedding glazing compound applicator includes a nozzle head that is configured to fit within the gap between the interior surface of the sash and the outer edge of the viewing element when in the dispensing position;

dispensing back bedding glazing compound between the glazing leg and the viewing element; and

retracting back bedding glazing compound applicator assembly to the stored position.

2. The method of claim 1, further comprising fixing the sash onto the glazing table such that the sash is prevented from moving during the glazing method.

3. The method of claim 1, wherein a portion of the position members contact the interior surface of the sash when the distal end contacts the glazing leg.

4. The method of claim 1, wherein the position members each further comprise a tip element secured to the distal end thereof such that when the position members are moved to the extended position, the tip element contacts the glazing leg.

5. The method of claim 4, wherein the tip element of each position member contacts the interior surface of the sash when the tip member contacts the glazing leg.

6. The method of claim 1, wherein the viewing element is a layer of glass.

7. The method of claim 1, wherein the viewing element is an insulating glass unit assembly.

8. The method of claim 1, wherein the viewing element is pushed against each of the distal ends after being placed within the sash opening.

9. The method of claim 1 further comprising actuating a depth probe between a stored position and an extended position, wherein actuating the depth probe extends a distal end of the depth probe through the gap defined between the interior surface of the sash and an outer edge of the viewing element to detect the distance that the nozzle head must be actuated to place the nozzle head in the dispensing position;

and wherein depth probe is returned to the stored position after the distance is detected.

10. The method of claim 1, wherein the glazing leg further comprises an upwardly extending lip disposed on an outer edge of the glazing leg, the lip cooperating with a bottom surface of the viewing element and the glazing leg to define a glazing groove that is in fluid communication with the gap;

wherein the back bedding glazing compound is dispensed in the glazing groove.

11. The method of claim 10, wherein the nozzle head is configured with an opening formed on a side surface thereof, and wherein the opening is oriented towards the glazing groove when the nozzle head is in the dispensing position.

12. The method of claim 1, wherein the back bedding glazing compound applicator is manually moved from the stored position to the dispensing position.

13. The method of claim 12, further comprising providing a position indicator, wherein the position indicator indicates the position of the nozzle head prior to being placed in the dispensing position.

14. The method of claim 1, further comprising actuating a stabilizer assembly from a stored position to a dispensing position, wherein the stabilizer assembly is configured to impart a predetermined force on the viewing element while the back bedding glazing compound is being dispensed between the glazing leg and the viewing element.

15. The method of claim 14, wherein the stabilizer assembly comprises a biased roller ball that engages a top surface of the viewing element to impart the force on the viewing element.

16. The method of claim 15, wherein the stabilizer assembly and the back bedding glazing compound applicator assembly is integrally fixed with respect to one another such that movement of the back bedding glazing compound applicator assembly causes the stabilizer assembly to move.

17. The method of claim 1, wherein the back bedding glazing compound is dispensed along a common plane until it reaches an intersecting plane, whereby the nozzle assembly is retracted and the back bedding glazing compound applicator assembly is re-oriented with nozzle head being returned to the dispensing position in the intersecting plane.

18. The method of claim 1, wherein after the back bedding glazing compound applicator is retracted into the stored position, the sash is moved a transfer conveyor.

19. The method of claim 1, wherein the back bedding glazing compound has a cure time about 5 minutes.

20. A method of glazing a sash, comprising:

placing a sash on a glazing table, wherein the sash defines an opening therein, a glazing leg extending into the opening in the sash;

actuating at least two positioner assemblies, each positioner assembly having a position member defining a distal end, and wherein each position member is selectively slidable between a stored position and an extended position;

wherein the positioner assemblies are actuated such that each position member is moved into the extended position such that the distal end of the positioner member contacts the glazing leg of the sash;

inserting a viewing element into the sash opening and abutting the viewing element against portions of the positioner members so as to create a gap between an interior surface of the sash and an outer edge of the viewing element;

retracting the positioner members;

simultaneously actuating a back bedding glazing compound applicator assembly and a stabilizing assembly to move from a stored position to a dispensing position, wherein the back bedding glazing compound applicator includes a nozzle head that is configured to fit within the gap between the interior surface of the sash and the outer edge of the viewing element when in the dispensing position and the stabilizing assembly is configured with a roller ball element that is configured to impart a predetermined force on top surface of the viewing element while the back bedding glazing compound is being dispensed between the glazing leg and the viewing element so as to prevent the viewing element from pushing the viewing element upwardly in response to the back bedding glazing compound being dispensed;

dispensing back bedding glazing compound between the glazing leg and the viewing element while the stabilizer assembly imparts the predetermined force on the top surface of the viewing element and while the back bedding glazing compound applicator assembly and stabilizer assembly moves along the perimeter of the sash opening defined by the glazing leg; and

retracting back bedding glazing compound applicator assembly and the stabilizer assembly into the stored position after back bedding glazing compound has been applied along the perimeter.
