My invention relates to and has particular 'I reference to Windows for housinsT having sash frames movable up and down.

Conventional windows having vertical movable sash frames have a disadvantage in that it is diiiicult and even dangerous to wash the outer sides of the window panes. Numerous devices have been invented to facilitate this task but they have a disadvantage in being cumbersome, eX- pensive and dicult to handle.

My invention has for its object to provide a window of a simple and inexpensive construction, in which the sash frames, while being movable up and down in the same manner as conventional sash frames, being for instance, provided with counterweights on ropes to facilitate such movement, are also rotatable on horizontal axes in a vertical plane so that each sash with its glass pane can be placed in a horizontal position or even lower, so that the outer side of the pane can be easily and conveniently washed and cleaned from inside the room.

An allied object of my invention is to provide means to yieldably align the sash frames in their normal operating position and to seal the clearances between the relatively movable parts.

Still another object of my invention is to provide a windowframe having vertically extending compartments with removable covers for the ropes and weights, so constructed that the latter can be inspected and repaired without taking apart the window casing as is the case with conventional windows.

The foregoing and other objects and features of my invention are more fully described in the accompanying specication and drawings which:

Fig. l is a perspective View of my 'window in which the sash frames are partly turned on the vertical axes for exposing the outer sides of the glass panes;

Fig. 2 is a front View of section;

Fig. 4 is a similar sectional viewvshowing the sash frames moved in a vertical direction for a normal opening of the window;

Fig. 5 is a horizontal sectional view on an enlarged scale showing the connections between a guiding bar and its associated vertical frame member;

Fig. 6 is a detail View of a sealing 'rcdgand the same partly in inv Fig. 7 is a sectional detail View of the frame on an enlarged scale.

My window comprises a window frame having vertical boards 5, 6 connected at the top and at the bottom by horizontal boards 1, 8 respectively, thus forming a rectangular frame. The horizontal boards extend at the ends beyond the ends of the vertical boards, forming compartments for sash weights S, le. The compartments or boxes are closed at the sides by front and rear cover boards 3, 4 secured to the vertical boards 5, 6 by screws il to facilitate their removal for inspection or repair of the weights or cords.

Either the inner 4 or the outer 3 cover boards may be removed for such an inspection as desired.

Upper and lower sash frames l5, l5 respectively have window panes I l, I8 and are slidably fitted in grooves 23, 24 in guiding bars i9, 20, which grooves may be formed by guiding strips i2 and a control strip I3, as shown more clearly in Fig. 5. The bars I9, 2i) are rotatively supported at the inner sides of the vertical boards 5, B by bolts 2i with nuts 22. The bolts of each pair of guiding bars i9 and 29 are aligned and pass through the central portions of the bars so that the bars can be rotated on the bolts as on trunnions. Each pair of the bars I9 and 20` can be rotated as a unit, the bars being connected by the sash frames l5, I6.

As may be seen, for instance, in Figs. 3 and 7, the grooves 23 are used for the lower sash frame, and the grooves 24 are used for the upper sash frame. The upper and lower respective grooves are aligned, forming continuations of each other, when the bars i9, E@ are placed in a vertical position.l In such a position of the guiding bars, the lower sash frame can be moved into the upper grooves and the upper sash frame can be moved into the lower grooves as shown in Fig. 4'.

To hold the guiding bars in their aligned position, rods 2l, 23 are provided and placed partly in vertical slots 29 in the boards 5, E and partly in corresponding slots 3) in the guiding bars I9, 20. The rods are movably supported on bolts 3| slidably extending through corresponding holes in the boards 5, E. Springs 32 are placed between the rods and the bottoms of the slots for urging the rods outward. Heads 33 limit the outward movement of the rods when the guiding bars are rotated. The springs are just strong enough to retain the guiding bars in their vertical alignment but the bars can be easily pushed out of this alignment for rotation ina vertical plane. The rodsat the same time serve as sea-ling devices for preventing any rain water from penetrating through clearances at the sides of the guiding bars.

The clearance between the upper side of the lower sash frame and the lower side of the upper sash frame is closed by a bar 35 secured to the lower sash frame as shown more clearly in Fig. 3.

To facilitate the rotation of the sash frames, the guiding bars are trimmed at an angle where they join each other in the middle of the window at 36. The upper and lower ends of the guiding bars and of the sash frames are also trimmed at an angle, engaging in their closed position correspondingly trimmed inclined sealing boards 25, 26. Such an arrangement of the tapering surfaces, besides facilitating the rotation of the sash frames, provides for a tight seal between the relatively movable surfaces when the window is closed.

The sealing boards are tapered down outwardly so that the rain water cannot creep over the lower board 26 into the room back of the window. The same purpose is achieved by the inclined junction in the middle of the window between the ends of the guiding bars.

Another advantage of my construction is that the sash frames can be turned in a vertical plane as show in Fig. l so that both sides of the window panes can easily be cleaned and washed from inside the house. Moreover, they are so inclined that the water used for their washing runs outside the window and cannot escape into the room. Metal strips 52 are mounted at the inner sides of the boards 5, 6 to reduce the friction between the guiding bars and the boards when the bars are rotated, also to provide an additional seal between the relatively movable surfaces.

For connecting the weights 9, IU to the sash frames, they are provided with eye bolts 40 secured in the outer edges of the sash frames and pass through slots 4|, 42 in the boards 5, 6 and guiding bars I9, 20 respectively as shown more clearly in Fig. 5. The eye bolts are located on the level of the trunnion or pivoting bolts 2l when the Window is in a closed position. The slots 4I, 42 are enlarged at these points to facilitate the rotation of the guiding bars in a vertical plane. The upper and lower slots 4|, 42 register with each other when the window is closed as may be seen, for instance, in Figs. 3 and 4, so that the eye bolts can pass from the slot in one guiding bar into the corresponding slot in the other guiding bar when the sash frames are moved up or down.

The sash frames are counterweighted by weights 9, I at the ends of cords or chains 41, 48 passing over blocks or pulleys 49, 50 supported at the undersides of the end portions of the upper board 1. The weights and cords are located in the end compartments of the window frame and can easily be inspected or repaired by removing boards 3 or 4 which are detachably securedby screws H. This work obviously can be performed by ordinary occupants of the house, without the necessity of engaging a skilled carpenter as is usually necessary with conventional counterweight suspension.

It is obvious that the sash frames can be turned in the vertical planes into a more or less inclined position as shown in Fig. l not only for cleaning but also for opening the window when it rains, to prevent rain water (or snow) from getting into the house, the rain drops readily `bowing outward from the inclined glass panes.

It will be understood that various features and `to be moved in a vertical principles of each of the embodiments o the invention above described or referred to may be utilized or substituted in the other embodiments.

Thus, it should be noted that the term boards employed herein should be taken in its broadest sense and not as a limitation to any particular materiali It is obvious that my invention is equally applicable to windows made partly or entirely of wood, plastic compositions, metal, etc.

While the invention has been described in detail with respect to certain particular preferred examples, it will be understood by those skilled in the art after understanding the invention, that various changes and further modifications may be made without departing from the spirit and scope of the invention, and it is intended therefore in the appended claims to cover all such changes and modications.
