ADOLPH MAEULEN, OF WILLIAMSPORT, PENNSYLVANIA, ASSIGNOR TO WILLIAMS- PORT MIRROR & GLASS COMPANY, OF WILLLAMSPORT, PENNSYLVANIA.

WINDOW-VENTILATOR.

Specification of Letters Patent.

Patented June 1G, 1914.

To all whom it may concern Be it known that I, ADoLPH-MAEULEN, a citizen of the United States, residing: at Williamsport, in the county of Lycoming and. State of Pennsylvania, have invented new and useful Improvements in Window-Venti- J lators, of which the following isal specificax tion.

The invention particularly relates to window ventilators employing a transparent front plate and collapsible. segmental side members of extremely light and strong construction.

In connection with the accompanying drawing, forming a part of this specieation j and wherein like numerals of reference designate corresponding parts throughout the several views: Figure 1 is a view in side ele- -vation of the side or end members of the ventilator with the front plate'and window v structure in vertical sect-ion.' Fig. 2 is a .ver-

tical sectional view Ithrough .the side .or .endf

member; Fig. 3 is a transverse sectionali v1ew taken through Fig. 2 on the line 3 3. Fig. 4 is a View in side elevation of aportion of a modified form of side .or end member with the front plate in vertical section. Fig. 5 is a side elevat-ion of a rear portion of Fi 4. Fig. 6 is atop plan view of a modie form of side or end member. Fig. 7 is a view in elevation of a portion of the form of Fig. 6, and Fig. 8 is a vertical sectional view taken through Fig. 1 on the line 8 8.

Reference numeral 1 designates the window frame, 2 the window sill, and 3, the window sash, to which the invention is applied. The invention consists broadly of a front glass plate 4 and two sides or end members. In the drawing onl one side or end member is illustrated, but 1t will be understood that there is aside or end member attached to each end of the front plate 4V and toeach side of the window frame. Each side or end member consists of two segmental plate sections 5 and 6. The side plate 5 is bent inwardly at right angles entirely along its front edge forming a fiange 7 behind which the glass front plate 4 is placed. The front plate 4 is engaged along 4its opposite or rear side by a flange 8 of a separate L-shaped bar, the other flange 9 of said bar bearing flat upon the side plate 5. The flange 8 is adjustable toward the flange 7 by means of bolts 10 to securely clamp the front plate 4. The upper edge of the plate 5 is vcnt out as at 12 thereby providing spaced :lugs or stops 14-1-5, one adjacent each side .edge of the plate 5. 'The side plate 6 comprises f-ront and rear spaced walls 16 and 17,

lintegrally connected along their side edges as at 18, by bending one from the other. The upper end portion 19 of the wall 17 is bent over upon the wall 16 closing the upper end of the plate 6 against entry of rain water. A portion 20 of the wall 17, which extends as at 21 beyond the side edge of the wall 16 throughout, is bent around the side edge of the wall 16 embracing between itself and said wall 16 the bent over portion 19 of the Wall 17 the former openings 22 permitting i-nsertion of a screw driver to drive screws 22 into the apertures 22 to secure `the plate 6 to the side 1 of the window frame. The plate 5 is inserted 'between the walls 16 and 17 of the plate 6, the stop 2O .being received in the cut-out portion 12 and ,engageable' with stops 14 and 15. Both plates 5 and 6 at their lower ends have registering openings to receive pivot screw 25 which passes into the` window sash. Vhen secured together in this manner, 'the plate 5 is freely movable between the walls 16 and 17 of plate 6, the-stop 15 engaging stop 20 preventing entire withdrawal of plate 5 In the modified forms, the plates vfand 6 are the same as in Fig. 1, except ,vv/ith respect to the receiving portion for/the front plate 4. In Figs. 4 and 5 the/,L-bar 26 is similar to the bar 8-9 of Fig. 1 though turned around. This bar has beaded fastenings '27 which enter openings 28 and slide into diagonal slots 29 in the plate 5 to crowd the bar against the glass front plate 4. In Figs. 6 and 7, the side portion of plate 5 is bent to provide inwardly extending double wall flange 30 and single flange 31, connected by portion 32 alined with the body portion of theplate 5. Between these par- ` allel flanges 30 and 31, the glass front pla'te is inserted.

What/is claimed as now is 1. In a window ventilator, a segmental side/plate having means for connection with a r,front member, a second segmental side plate having double walls and slidably receiving between its walls the first plate, a

stop extending across the space between the 116 Y Walls of the second plate, the first plate haning a cut out portion receiving said stop and the end Walls of the cut-out portion being engageable with the stop to arrest movements of the irst plate in the second plate, and said plates being pivoted together.

2. In a Window ventilator, a segmental side plate having means for connection with a front member, a second segmental side plate bent upon itself and slidably receiving between its Walls the first plate, one Wall of the second plate extending beyond the other Walland the same Wall having a portion bent around the' said other Wall forming a stop, the first plate having a cut-out portion receiving said stop; ,M Y

3. In a Window ventilator, a segmental side plate having 'means for connection With a front member and also having a cut-out portion, a second segmental side plate bent upon itself forming double Walls, the upper edge f one Wall being bent upon the other Wall, a portion of the side edge of one Wall being bent upon the other Wall forming a stop, said plates being pivoted together with the stop received Within the said cut-out portion. Y

4. In a vvindoitT ventilator, a segmental side plate having means for connection with a front member, stops extending beyond said upper edge, a second segmental sido plate of double Wall formation, the Walls being connected along their side edges, the upper edge of one Wall being bent around the other Wall, a portion of the side edge of one Wall being bent around the other Wall and constituting a stop, the side'edge of one of said walls extending beyond the other and beyond the last-mentioned stop, the first side plate being slidably received between the Walls of the second side plate, the stop of the second side plate being received between the stops of the first side plate, and the said plates beting pivoted together adjacent their lower en s.

5. In a Window ventilator, a side plate having a right angular flange along one edge, an L-shaped member having one of its flanges parallel With and movable with relation to said right angular flange, and the other flange of the L-'shaped member bearing flat upon the said side plate.

In testimony whereof I have hereunto set my hand in presence of t-Wo subscribing witnesses.

ADOLPII MAEULEN.
