My invention relates to improvements in vertically swingable sash windows for dwellings and the like.

The primary object of the invention is to provide a weatherproof window with vertically spaced and swingable metal sash frames adapted to open upwardly and outwardly and which are rust-proof, non-corrosive, and especially designed to be manufactured at a lower cost than present-day metal sash frames and without expensive shop equipment.

Another object is to provide such a window with metal sash frames which will drain water and moisture out of the same so as to prevent the accumulation thereof at the bottoms of the sash frames with consequent rust corrosion, and leakage at the lower edges of the sashes.

Still another object is to provide a window of the character above set forth in which glass panes are sealed in meta1 sash frames and may be easily and quickly installed therein and replaced without the use of putty and the like.

Still another object is to provide a window of the character specified in which the sash frames and other parts may be inexpensively stamped out of sheet metal so as to avoidthe use of expensive extrusions.

Still another object is to provide inexpensive, simply constructed operating means for easily and quickly opening and closing the upwardly swingable sashes.

Other and subordinate objects within the purview of my invention, together with the precise nature of my improvements, will be readily understood when the succeeding description and claims are read with reference to the drawings, accompanying and forming part of this specification.

In said drawings:

Figure 2 is a View in vertical section taken on the line 22 of Figure 1 with the sashes shown open in broken lines;

Figure 3 is a View in horizontal section taken on the line 33 of Figure 1 and partly broken away and drawn to a larger scale;

Figure l is a view in vertical section of the upper half of the window taken on the line 4-4 of Figure 1 and drawn to the same scale as Fi ureB;

Figure 5 is a similar view of the lower half of the window taken on the line 5-5 of Figure 1;

Figure 6 is a view in perspective of the parts of one of the sashes disassembled;

Figure 7 is a view in perspective of the sealing strip between the top of the uppermost sash and the window frame, together with the keeper and water shed bar therefor, detached and disassembled.

Referring now to the drawings by numerals, according to my invention, as illustrated, a window is provided comprising a window frame l, preferably aluminum, suitably fitted and secured in the window opening 2 in a wall 3 and comprising a header 4, side stiles 5, and a sill member t preferably set against an inner shoulder l in the wall 3. A pair of flat side, stop ribs 8 extend vertically along the side stiles 5 and are spaced inwardly of the front of said frame I a distance suitable for a purpose presently seen. The sill member 6 is rabbeted along its upper, front edge to form a stop shoulder 9 on said member flush with the outer sides of the side stop ribs 8. A header rib i 0 extends along the bottom and front edge of the header 4 between said ribs 8. The side stop ribs 8, stop shoulder 9, and header ribs Iii are preferably formed integrally with the window frame I and serve a particular purpose presently seen.

A plurality of vertically spaced sashes H are provided in the window frame I to open outwardly and upwardly, three being shown in the present instance, and which will now be described.

Each sash ll comprises a sash frame [2 including a pair of substantially triangular, fiat, side frame members [3 of non-corrosive rustproof, sheet metal, preferably sheet aluminum, and which taper edgewise downwardly and are pivoted at the upper Wider ends thereof, as by pivots It, to the side stop ribs 8 in opposite sides of the window frame I to swing about an horizontal axis and lie flat-wise against said ribs 8 when the sashes H are closed, but, with sulficient clearance to prevent frictional binding of the same against said ribs 8. Each pair of side frame members I 3 at the upper ends thereof project inwardly of the window frame I past the side stop ribs 8 for a purpose presently apparent.

An upper stamped out cross bar !5, of obtuse angled cross section, and sheet aluminum, extends between and connects the upper ends of each pair of side frame members 13 and is secured thereto, flush with the upper and outer side edges of said members l3, by a pair of flanged ears 16, I! on each end of said bar, one of the ears E5 of each pair being bolted, as at it, to the adjacent side frame members it, and the other cars l? ofeach pair being bolted, as at E5, to a right angled edge flange 2% on the upper end of the adjacent side frame members it. The cars ii in each pair ar also bolted, as at 22, to the adjacent side frame members It. The pivots Hi extend through the ears I? and the side frame members 53 of each sash frame it and may take the form of wooden screws, as shown, if the window frame 5 be formed of wood. Suitable bolt holes 23, 2d are provided in the ears l5, i'l and bolt holes 25, E6 in the flanges 25 and the side frame members i3, for the described bolts, and holes 2?, 28 are provided in said ears ii and the side frame members it for the p vots i The upper crossbar 55 of each sash frame 13 forms a downwardly and outwardly slantin top 29 for the sash frame for a particular pur-- pose presently apparent.

A weatherproof seal is provided between the top 29 of the uppermost sash frame l2 and the window frame l, to seal said sash frame at the top, when said sash frame i2 is closed. For this purpose, a double thickness felt, sealing strip 39 is attached by screws 3| to the bottom of the header rib is to extend along said rib and lie, when the sash frame i2 is closed, over and on the top 29 of said sash frame 2 to be clampingly engaged at its inner folded edge by said top 29. In this connection, it is to be noted that the pivots i i of the side frame members it, or sash frames [2 are located forwardly of the inner edge of the sealing strip 36 so that the uppermost sash H is swingable downwardly and inwardly into closing position with the top 29 thereof adapted to swing outwardly and upwardly into clamping engagement with said sealing strip 36. This results in a weather-tight and otherwise efiicient seal between the top 29 of the uppermost sash frame l2 and the header t of the window frame I.

A keeper and water-shed bar 32, of stamped out sheet aluminum, is secured by the screws 3| to the bottom of the header rib l and to the front edge of the sealing strip 363 and extends forwardly out of the window frame 1 to prevent rain and the like from beating inwardly past the top 29 of the uppermost sash frame E2. The keeper and water-shed bar 32 is of zig-zag form in cross section to fit against the sealing strip 39 and said rib ill. Suitable holes 33, 34 are provided in said sealing strip 3!} and bar 32 for the screws 3|.

Sealing means is provided between the sides of the sashes l i, when closed, and the front edges of the side stiles comprising the following. The side frame members it of each sash frame I2 are provided at the front edges thereof with outwardly and laterally offset channel-flanges 36 of rectangular shape in cross section and which overlap the cross bar is below the top 29 of the sash frame and depend below the lower ends of said side frame members it with open sides confronting. The channel flanges 36, when the sash frames [2 are closed overlap and fit flush against the front sides of the side stiles 8 and form weather-tight seals at the sides of the sashes I I. The channel flanges 38 are formed with bottom end gaps 3'! in the rear sides thereof and with right angled bottom ears 38 for a purpose presently seen. At the upper ends thereof, the channel flanges 36 are open and each is provided with a front forwardly offset, beveled end portion 39 and an exposed rear side extension Ml between said portion 39 and the flange 2| all for a purpose presently apparent.

A plate glass pane M for each sash i l is fitted at its side edges in channel sealing strips 42 of felt fitted in the channel flanges 36, the bottom edge of the pane ll resting on the bottom cars 33 are being supported thereby. The channel sealing strips #12 opposite the gaps 3'! are cut away, as at 53, so that the lower edge portion of the glass pane M is exposed on the rear face thereof from side to side of the pane. At the upper ends thereof the channel sealing strips G2 are provided with front cut-outs 44 so that the fronts of said strips terminate in the portions 39.

A particular feature of my invention is means for forming a weather-tight seal along the upper edge of the pane ii of each sash ii, and a seal between the lower edge of each sash H and the next lower one, all as now to be described.

As best shown in Figures 4, 5 and 6, a folded felt sealing strip 46 is extended along the front side of the cross bar 15 of each sash frame l2 with a double thickness portion 41 riveted, as at 8, to said bar above the pane ll and said strip below the rivets 48 straddling the upper edge of pane ii. The cut-outs M and the open ends of the sealing strips 42 fit against the lower edges of the sealing strips 41. A keeper bar 56 of zig-zag cross-section, and stamped out sheet aluminum, extends along said sealing strip 4! and is riveted in place by the rivets 48, said bar overlying the sealing strip ll and upper edge of the pane M in front of said pane and being spaced downwardly of the sealing strip ll to leave a double thickness portion of said strip exposed above said keeper bar 5E. The ends of the sealing strips 46 and of said keeper bar 50 extend into the channel flanges 36 and both said strips and said bar conformably fit into forwardly offset portions 39 and close the upper ends of the channel flanges 36 with the back of the sealing strip 3! fitting above said ends against the extensions 40 of said channel flanges. Suitable rivet holes 5| 52 are provided in said strip 48 and said bar 59. The exposed lower edge portion of each pane 5|, when the sash frames 12 are closed, overlap and fit the sealing strip 46 of the next lower sash frame l2 above the keeper bar 50 so that the sashes II are sealed at the lower edges thereof, when closed, without glass engaging glass, or metal, and whereby a perfect and weathentight seal is formed.

Operating mechanism for opening and closing the sash frames i2 is provided comprising a worm gear casing 55 secured in the bottom of the window frame l by screws 56 to one of the side stiles 5, and containing a worm 5? and a worm gear 53, both operative about horizontal axes. The worm 5? is provided with a shaft 59 extending inwardly beyond the window frame I for operation by a suitable hand crank (iii. A crank arm 6i fast on the shaft 52 of the worm wheel 5'1, for vertical swinging by said shaft 62 extends toward the lowermost sash H through a slot es in said casing 55. A vertical, operating channel bar 55 of stamped out sheet aluminum is pivotally connected to the upper ends of the side frame members l3 of the sash frames l2 in rearwardly offset relation to the pivots M of said frame members i 3. The pivotal connections of the operating bar at to said members l3 comprise, in each instance, an aluminum bracket plate 65 which is riveted at 66, to the channel side of said bar (it with a central lateral pivot stud 6'! extending through an upper end aperture 68 in the associated side frame members it. A link 69 operatively connects the crank arm 6! to the operating bar 65 with a lower end pivoted, as at 78, to said arm Bi and its other end pivoted to the lower end of said bar 64 by a pivoted stud ll on a bracket plate if like the bracket plate 55. Suitable washers l3, 14 may be provided on the pivot studs 61, l I. As best shown in Figure 3 the operating bar fit, the link $53 and the crank arm 61 are disposed between the side frame members i3 of the sash frames 12, at one side of the sashes ii, and the adjacent side stile 5, a space being provided for that purpose by pivoting said sash frame members it on the side stop ribs 8.

By operating the hand crank 60, the operating bar 64 may be moved vertically, with lateral play, compensated for by the link 69, to swing the sashes l i vertically and upwardly from closed position shown in full lines in the drawings into selected open positions with a limit of opening movement, as shown in broken lines in Figure 2, established by engagement of the top 29 of the uppermost sash frame l2 with the keeper and water shed bar 32. With the sash frames [2 closed, the same are effectively sealed, in the manner previously explained. The described sash frames l2 provide for sealing the panes i! therein, without putty, or the like, and by bending the bottom cars 38 of the channel flanges 36 downwardly, said panes M, with the sealing strips 42 thereon, may be slid upwardly in the channel flanges 35 for installation or replacement purposes and then looked in the sash frames l2, which is to say, in the channel flanges 35, by bending said bottom cars 38 back under the lower edges of the panes M. As will be seen, installation or replacement of the panes fl is rendered quick, easy and safe.

Any suitable type of screen 15 may be fitted in the window opening 2 against the window frame I in the rear of said frame.

The foregoing will, it is believed, suffice to impart a clear understanding of my invention, without further explanation.
