VENTHAING WINDOW-BASE.

To all whom t may concern.'

Be it known that I, Amun L. EvANs, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented new and useful Improvements 1n be swung outwardly Ventilating Window-Sashes, of which the following 1s a specification.I

In carrying out the present invention, it is my purpose to provide a ventilating window sash wherein supplemental Sashes may from the main sash to provide an opening for the admission of air into the room' or compartment and wherein the glass will be arranged in sections, so formed and correlated as to prevent the admission'of rain, snow or the like to the room or compartment when the glass is swung outwardly from the sash.

iVith the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claims.

In the accompanying drawings; .Figure 1 is a front elevation of a window sash constructed in accordance with the present invention.

Fi 2 .is an edge elevation of the same 'showlng the parts in open position.

Fig. 3 is a vertical sectional view there through.

. through the same.

- Fig. 5 is an 'enlarged detail view.

Fig. 6 is a similar view. Referring now to the drawings in detail, 1 designates a main sash or frame embodying top and bottom rails 2 and 3 respec-l tively and side Stiles 4. This sash 1 is adapted to be mounted ,in a window casing and is capable of vertical sliding movement therein as usual, and the inner surface of the bottom rail of the sash is provided with a tinger hold 5 to facilitate theraising and lowering of the sash. In they present instance, the outer surfaces of the top, and bottom rails and the side stiles of the sash contiguous to the inner edges of such rails and stilcs are rabbeted as at 6 and arranged within the sash adjacent to the respective stiles thereof are Lshaped frames 7. The vertical bar of each frame 7 is disposed within the rabbet of the adjacent stile and Specication of Letters Yat/ent.

' The converging is a horizontal sectional.v 'view` These hinges 8 are countersunk in the side stile of the sash. r[he lo'wer horizontal bars of the frames 7 are dis osed within the rabbeted portion of the ottom rail 3. Suitvably secured in each frame 7 is a right angular triangular section of glass 11 or other transparent material and the inclined edges of the glass sections confront each other. Each frame 7 and glass 11 carried'thereby forms what will be termed a triangular suplemental sash. The lass sections carried y the frames 7 are o? less width than the sash 1. Within the sash 1 is a relatively large trapezoidal frame 9 embodying a top bar, side bars depending from the top bar and converging toward each other at their lower ends, and abottom bar connecting the side bars at the lower extremities thereof. side bars of the frame 9 overlie the glass 1l in the frames 7 and the lower bar of the frame 9 is adapted to tit into the rabbet in the bottom rail of the sash, while the top in the upper rail of the sash. The top bar of the frame 9 is connected to the top rail of the sash by means of horizontal hinges 10 that are countersunk in the upper rail of the sash frame. Mounted in the frame 9 is a plate 11 of glass or other transparent material and the inclined edges of the glass sections 11 bear against the under surface of the plate 11. The frame 9 and plate 11 form what may also be termed a trapezoidal supplemental sash.

In the present instance, the lower bars of the respective frames 7 are equipped with hook-shaped keepers 12 having rather long upstanding bills which slidably engage the bottom bar of the frame 9 so that in the outward and inward movements of the frame 9 corresponding movements will be imparted to the frames 7.

In this form of my invention, the bottom bar of the frame 9 is equipped centrally with an eye 13 and connected to the eye 13 is one end of a strip 14 formed with openings 15 spaced apart longitudinally of the strip. Mounted in the inner edge ot' the bottom rail of the sash is a in 16 disposed in line with the eye 13, whi e arranged to one side of the nin 16 is a pin 17. Formed on one edge of the strip 14 is a depending lip 18 designed to overlie the bottom rail of the sash in one position of the Strip.

it is desired to ventilata the room or compartment bar its into the rabbet Patented rei. as, taie.

the sash in the window casing. the frame 9 is swung outwardly from the sash in a. vertical plane, thereby automatically swin g the frames outwardly in a horizontal p ane, and in the outward movement of these frames a space 'is' formed :between the su plemental frames'and the bottom rail of t e sash whereby the .air may pass through they sash and into the compartment. When the frames 9 and 7 are swung outwardlyto the desired position, the strip 14 is moved to engage one of the openings 15 with the pin 16 so as to hold the frames in open position.

The side bars of the frame 9 are referably formed with outwardly pro]ecting flanges 19 lined withrubber, felt or the like that 'frictionally engage the glass carried by the frames 7 so as to form weather proof joints between the frames 9'and 7 to prevent the entrance of rain, snow and the like to the compartment when the'frames are in open or c osed positions. y

To close the frame, the stri 14 is disengaged from the pin 16 and pu ledinwardly, thereby swinging the frames 9 and 7 into the sash'. The opening at the inner end of the strip 14 is offset from the remaining openings and-when the frames have been drawn into the sash, this otlset opening is engaged with the pin 16 and the strip 14 swung about the pin 16 asa fulcrum, thereby drawing the. frame tightly 'into the sash. Succeeding the swinging of .the strip 14 one of the openings 15 is engaged with the pin 17 and the lip 18 engaged with the bottom rail of the sash in order to hold the strip 14 against accidental movement.

The upper end portion of the side bars of the frame 9 are relatively thick as shown in the drawings so that the upper end of the glass sections 11 in the frame 7 will be comthat I do not limit or coniine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope oit the claims and without departing from the spirit of the invention.

I claim:

1. In a Ventilating window, a pair of triangular sashes hinged at the sldes of the window opening for horizontal swinging, and a third sash hinged above the triangular sashes for vertical lswinging and adapted when in extendedv position to be supported upon the hypotenusal edges of said pair of sashes. v

` 2. A pairof triangular sashes mounted at the sides of a window opening on vertical hinges for horizontal swinging, a third sash supported on horizontal hinges at the top of the window opening for vertical swinging, its sides overlying the first named sashes and adapted to be' supported upon their free edges when all sashes are open, and connections on the lower bars of the first named sashes slidably engagingv the last named sash as all lsashes are moved to closed position.

3. In a. Ventilating window, thev combination with a main frame; of triangular sashes hinged to the side stiles thereof for horizontal swinging, Aand a third sash hinged for vertical swinging and with its sides overlying the triangular sashes in any position of parts and abutting their hypotenusal edges when the sashes are open.

4. In a Ventilating window, the combination' with a frame; of a right-angular supplemental frame hinged in each side stile thereof and adapted to close into the bottom rail, triangular glasses in these frames, a fourth frame hinged in the top rail with its sides adapted to overlie said glasses and its lower bar to lie against the bottom rail when this frame is closed, a glass in the fourth frame, and hook-shaped kee ers on the lower bars of the said right-angu `ar frames whose bills slidably engage the lower bar of said fourth frame, for the purpose` set forth.

In testimony whereof I atlix my signature. 100
