10 Claims.

This invention relates to window operators; and has special reference to windows including a vertical series of sections supported for swinging movements on horizontal axes from and to closed and open positions.

Objects of the invention are to provide an improved window including a vertical series of sections supported by pivots extending from their ends through the vertical portions of the window frame, a vertically movable rack bar in each side member of the frame for rotating said pivots and thereby opening or closing the respective window sections; to provide novel metallic sash structure for the window panes including metallic frame -members shaped and formed to maintain necessary and desired rigidity indefinitely; to provide sealing Weatherstrip devices for maintaining sealed joints between the respective sections and also between the sections and the window frame; to provide connections operated by said rack bars for turning the pivots of the window sections to open and to close said sections; and to provide novel easily operated mechanism for moving said rack bars vertically as required to open the window sections successively and to close them in the same order.

Another object of the invention is to provide improved'operating mechanism for the window sections comprising levers connected with the pivots by which the sections are supported, vertically movable bars having racks thereon for engaging gear segments respectively and at different vertical positions of the rack bars in order to operate said levers and move the window sections, and means for sealing in weatherproof manner the respective window sections when they are closed.

Other objects will appear from the following description, reference being made to the annexed drawings, in which- Fig. l is an inner side elevation of a window constructed in accordance with the present invention.

Fig. 4 is a similar View showing all but one of the window sections open.

Fig. 5 is an enlarged view of one of the gear segments forming a part of the operating mechanism for each window section.

Fig. 6 is a side elevation of one of the cooperating lever members for movingthe window sections.

Fig. 7 is an enlarged vertical sectional view on the line 1-1 of Fig. 1, parts being omitted.

Fig. 8 is an enlarged horizontal sectional view on the line 8 8 of Fig. 1.

Fig. 9 is an enlarged horizontal sectional view on the line 99 of Fig. 1.

Fig, 10 is an enlarged sectional view on the line Ill-10 of Fig. 2, showing more clearly the connections for moving the window sections.

The window frame is mounted rigidlyin the proper opening in the building wall, and may include duplicate vetrical side portions each composed of angular members I, 2, and 3, attached together and to the building wall at the sides of 20 the window opening, and having their-upper ends attached to the'rigid frame device 4 and their lower ends attached to the rigid frame device 5.

A frame thus constructed provides vertical spaces 6 in the vertical side portions and a space I in 25 the'lower portion thereof. The operating mechanism for the window sections is mounted in these spaces and thereby concealed and protected. A vertical reinforcing bar 8 is attached to each vertical angular member I. The frame 6 further comprises angle bars 9 attached to the members I, the top member 4 and the bottom member 5. Angle bars l0 (Fig. 8) are attached to the angle bars 9 at the sides of the frame, and channel-members ll (Fig. 7) are attached to the 35 angle bars 9 along the top andbottom of the frame.

Resilient metallic sealing strips I2 are secured between the inwardly extended portions of'the angle bars 9 and ID at the sides of the frame, and have angularly extended arms l3 engaging the reinforcing bars 8. Resilient sealing weatherstrips M are attached between the-angle bars 9 and II at the top and bottom of the frame and extend outwardly therefrom for cooperation with 45 the respective window sashes.

Each end of the respective window sections comprises a metallic stripbent to provide a sup? porting portion IS, an outwardly extended pane abutting portion l6, anda laterally extended flange l'l contacting the adjacent member I. The lower ends of the end members of each window section are connected by a metallic strip bent to provide a portion [8, an outwardly extended pane abutting portion 19, and a down- Wardly extended margin 20. The upper ends of the end members of each window section are connected by a metallic strip bent toprovide an upper portion 2|, an inwardly extended abutting frame portion 22, and a downwardly extended flange 23 at the outer margin of the portion 2|. A reinforcing bar 24 may be mounted in the frame 22 wherever needed to prevent downward bending of the window sash. In instances where it is desired to divide the longitudinal area of any window sash to receive separate panes of window glass, T-bars 25 may be attached to the lower and upper horizontal portions of the respective window sashes (Figs. 1 and 9). The window panes 26 are mounted in the respective window sashes against the abutments I6, l9 and 22 and secured in position by putty 21, or otherwise as desired. The upper portion 2| ofeach window sash, excepting the uppermost window sash, has attached thereto an angle strip 28 constituting an abutment for the next adjacent window sash portion I8, while the flanges 20 of the respective window sashes engage the outer edges of the next lower window sashes when the window sashes are closed, as shown in Fig. '7. Resilient sealing weatherstrips 29 are attached to the angle members 28 for close contact with the lower edges of the adjacent window sashes when the windows are closed. These resilient weatherstrips 29 are in continuation of and in cooperative relationship with the strips I2 and M. The upper portion of the window frame includes an angle strip 39 cooperating with and extending downwardly beyond the top of the upper window sash at the outside to constitute a guard and protecting device, preventing the passage of water and other substances inwardly above the upper window sash. A bar 3| is attached to the lower frame device 5, has an abutment for the downwardly extended flange 20 of the lower window sash, and cooperates therewith to prevent inward passage of rain and other substances.

Each window sash is pivotally supported by a pair of axially alined pivots 32 attached to the ends thereof and extending through bearing sleeves 33 attached to and extending through the reinforcing bars 8 and the members I into the spaces 6. Levers 34 are rigidly attached to the outer ends of the pivots 32 within the spaces 6, and have slots 35 receiving rollers 36 rotatively supported by levers 3'! supported for turning movements on pivots 38 attached to the members 42 within the spaces 6 (Figs. 2 and 10). The levers 31 are attached by welding or otherwise to gear segments 39, also supported for turning movements on the pivots 38. By this construction and arrangement, the levers 3'! will move the levers 34 when said levers 31 are operated from the positions shown in Fig. 2' to the positions shown in Figs. 3 and 4 and beyond, and Vice versa.

A vertically movable rack bar 40 is mounted for vertical sliding movements in each vertical space 6 which are at the sides of the window frame. Each of said rack bars 40 is formed with a series of spaced racks 4| corresponding to the respective segments 39 and adapted to be moved successively into and out of meshing engagement therewith. The order in which the racks 4| may be engaged with and disengaged from the respective segments 39 may be varied as desired, so that the different window sections may be opened successively in any desired order and .Closed in the reverse order. These rack bars are mounted between and are guided by the levers 31 and guide elements 42 which are secured to the members by fasteners 43 (Fig. 8). The lower ends of the rack bars operate between guides 44 and 45 attached to the members substantially below the lower pivots 32 (Figs. 2 and 4).

In each space 6 a sprocket chain 46 has its ends engaged with the rack bar 40 and is engaged over upper sprocket wheels 41 and lower sprocket wheels 48. The lower sprocket wheels 48 are attached to the ends of a horizontal shaft 49 rotatively supported within the lower space A worm gear 50 is attached to the shaft 49 and is in permanent engagement with a worm 5| rigid on a short shaft 52 so that, when said shaft 52 is rotated, the chains 46 will be operated and the rack bars 40 moved vertically. A crank 53 is attached to the inner end of the shaft 52 so that said shaft may be operated manually as required to open and close the window sections.

As shown, the upper racks 4| will first engage the. upper segments 39 and thereby open the upper window section. Next, the lower racks 4| will engage the lower segments 39 and thereby open the lower window section, the upper racks 4| passing out of engagement with the upper segments 39 at the time the upper window section is in open position. At the time the lower window section is in open position, the lower racks 4| pass out of engagement with the lower segments 39. Thus, it is apparent that only the upper window section may be opened and kept open while the remaining window sections remain closed, or both the upper and lower window sec-- tions may be opened and kept open while the intermediate window sections remain closed. Or, as shown in Fig. 4, the intermediate window sections may be successively opened and kept open by continued upward movement of the rack bars 40.

When it is desired to close any or all of the window sections, the rack bars 40 are moved in the reverse direction to the extent required to close the selected window sections in the reverse order to that in which they were opened.

It is now apparent that this invention attains all of its intended objects and purposes efficiently and satisfactorily; sashes and operating mechanism are of strong and durable construction and may be varied widely within the scope of equivalent limits without departure from the principle of the invention.
