As shown in Fig. 2;the' 'supportmg means Jfo'r the double glazing Iii-lit r4 0" comprises a wooden till 1-"! which rests a m'etal sill plate la suitably secured thereto and provided along itsouter edge with a down-turned flange 1'9 overlapping the upper marginal portions of the adjacent facin'giipanels "12. wil l' be'noted, the upper'surface of the Wooden 'sill 'I 1 and 'metal sill iplate1-8 slant forwardly 'and downwardly to facilitate drainage o'f' 'water or moistureaway from thefun'it and the supporting means'therefor. It will "be I v evident that should the double glazing" unit 1. 0 he "set verti'oally on edg'e -u'pon the ineline'd metal To overcome "this; t he instant I rev-entity -pie'c e wedge-shaped member.
of the same length and width as the bottom member and is provided intermediate its side edges with a longitudinally extending tongue 23 adapted to bereceived within the groove 22, said tongue being somewhat thicker than the depth of the groove 22 so that when the top member is placed upon the bottom member, they are spaced slightly from-one another at opposite sides of said tongue as in Fig.2, to permit the top member to rock transversely upon said bottom member. Thus, when the double glazing unit I Ii is rested upon the top'member 21 in a vertical position, the said top member will automatically adjust itself transversely so that the upper suriace thereof will engage the lower edges of both of the glass sheets.
The sill I i may also not always be perfectly level longitudinally of the window opening, and in order to compensate therefor, the bottom sur-' face 24' of the top member 21 is longitudinally curved so that the block is thickest at its longitudinalcenterand becomes progressively thinner towards its opposite; ends, Because of this, the
-bloc'k cannot only rock transversely upon the tongue 23-but likewise longitudinally tov automatically adjust itself to any variations in the sill orsill plate. By this means, the weight of the unit. will be uniformely distributed. over both of the glass sheets, thereby reducing to a minimum the setting up ofstrains in the unit tend- "ing to rupture the seal or break the glass sheets. Itispreferred that the'upper surface of the top member 2| of the-setting block be covered with v a layerof material 25 which may consist of a :..strip 'oflead, leather, or other. like material. The
groove :22 and tongue 23 may be suitably rough ened, sandblasting ,or the like, to minimize .orprevent. slippage between the top and bottom members.
' The double glazing unitfll may be mounted in the window openingby any suitable type of metal sash construction. Asshown, by Way of example,
it is secured in'place. by thetwo metal sash secj-tions-2fi and'2l arranged at opposite sides of the unit and secured to the wooden sill. Each sash section comprises a metal strip 28 provided along one edge with an inturnedjflange 2S resting upon the sill or sill plate andal ong its opposite edge with an inturned 'flange 3!} bearing against the adjacent glass sheet. The sash sections are secured to; the wooden'sill by screws .31 which force the-flanges 28 upon the sill or sill plate and theflanges 30 against opposite sides of the double glazing unit. v In Fig. .4 is illustrated a somewhat different type of setting block which is particularly adapted for levelling a glazing unit where irregularities in the supporting structure will not be taken .up by the :setting block shown in Fig; 3 or Where the glazing unit, is of sufficient length as to require the use of three or more setting blocks as in Fig. 1.
.This block-embodies a modified base or bottom member 32 having a fiatbottom: surface 33 and an'inclined upper-surface 34 which results in a Provided in the upper inclined surface 34 is a longitudinally extending groove 35 for receiving the tongue 23 of the top member- 2! which is of the same type as shown .in- Fig. The bottom member 32 is somewhat .longerthan the top member so that. the top member may be moved along the inclined upper surface of the bottom member until the desired position with relation to the glazing unit has been obtained. Thus, with this type of setting block, the top member can beraised or lowered to com- -pensate for any.irregularity-in the supporting 4 structure and thereby bring the upper surface of the top member into the same plane as the top members of the setting blocks supporting the opposite ends of the unit.
It is to be understood that the form of the invention herewith shown and described is to be taken as the preferred embodiment of the same, and that various changes in the shape, size and arrangement of parts may be resorted to Without departing from the spirit of the invention or the scope of the subjoined claims.
What I claim is:
1. In a mounting for multiple glass sheet glazing units, a setting. block comprising a bottom' member and a top member carried upon said bottom member and adapted to support the glazing unit, on edge in a vertical position, the upper surface of said bottom member having a, longitudinally extending groove therein while the lower surface of said top member has a longitudinal- 13' extending tongue loosely received within said groove for rocking movement transversely thereof, said tongue being longitudinally convex to also provide for longitudinal rocking of thetopmember with respect to the bottom member.
2. In a mounting for multiple glass sheetglazing units, a setting block comprising a bottom member and a top member carried upon said bottom member and adapted to support the glazing unit on edge in a vertical position, the upper surface of said bottom member having a longitudinally'extending groove therein While the'lower surface of said top member has a longitudinally extending tongue rockably received within'said face of said top member has a longitudinally extending tongue rockably received within said groove whereby said upper member is rockable transversely with respect to said bottom member, the bottom surface of said upper member being curved longitudinally so that it isthickest at its center with gradually diminishing thickness towards its opposite ends.
' 3. In a mounting for multiple glass sheet glazing units, a setting block comprising a bottom member and a top member carried upon said bottom member and adapted to support the glazing unit on edge in avertical position, the upper surface of said bottom member having a longitudinally extending groove therein while the lower surface of said top member has a longitudinally extending tongue loosely received within said groove for rocking movement transversely thereof, said tonguebeing longitudinally convex to also provide for longitudinal rocking of the top member with respect to the bottom member, the bottom member being relatively longer than .the top member and having an inclined upper surface along which said top member may be moved to bodily raise or lower the same, the longitudinally extending groove in said bottom member being parallel to the inclined upper surface thereof.
4. In a mounting for multiple glass sheet glazing units, a setting block comprising a bottom member and a top member carried upon said bottom member and adapted to support the glazing unit'on'edge in a .verticalposition, the upper surface of said bottom member having a longitudinally extending groove substantially intermediate the side edges thereof while the lower surface of' with gradually diminishing thickness towards its PPWW? finds, the bottom member being rela- 5 6 tively longer than the top member and having an REFERENCES CITED inclined upper surface along which said top The following references are of record in the ber may be moved to bodily raise or lower the fil f this patent;
