6 Claims. (Cl. 20-42) This invention relates to improvements in window structures and has particular reference to awning-type or projected windows.

One of the principal objects of this invention is to provide a novel awning-type window wherein the opening and closing of two or more sashes or ventilators is controlled by manipulation of one of the ventilators;

Multiple operated awning-type windows have been proposed heretofore .but have not proven entirely satisfactory due to certain inherent disadvantages. For example, it is necessary, in order to operably connect together the two or more ventilators of each window, to utilize space-consuming linkage arrangements which must be shielded to eliminate the unsightly appearance of the linkage structure. The shielding and linkage structure contained therein is positioned interiorly of the building and presents problems with regard to screening, inasmuch as the screening must be on the inside of the window. Accordingly, with presently commercially available multiple operated awning-type windows, the screening must be such as to encompass the linkage structure, and hence the entire window. From a standpoint of expense and appearance, this is undesirable, since generally one of the lights of the window is stationary, yet must be unnecessarily screened. Such structures are further disadvantageous in that they are relatively complicated from a mechanical standpoint, present installation and maintenance problems and are relatively expensive. In other installations, due to the limitations inherent in the structure thereof, it is necessary to use an expensive dummy ventilator for the stationary light in order to permit the operative connection between the movable ventilators to be made. One of the principal objects of this invention is to provide a multiple operated awningtype window which is not subject to these disadvantages.

Another object of this invention is to provide a multiple operated awning-type window in which the moving parts are all behind the frame inside the building structure so as not to be exposed to the weather.

Another object of this invention is to provide a window of the type described in which the moving parts thereof may be removed therefrom and re-installed therein from the inside without affecting the building structure itself.

Yet another object of this invention is to provide a multiple operated awning-type window which is simple in construction and hence relatively inexpensive, easy to install and maintain, yet which is highly 'etfective in operation.

Other objects and advantages of this invention it is believed will be readily apparent from the following detailed description of preferred embodiments thereof when read in connection with the accompanying drawings.

In the drawings:

Figure 6 is a sectional view taken substantially on the line 6-6 of Figure 5.

Figure 7 is a perspective detail view showing the stabilizer shoe, its shaft and associated lever arm.

Figure 8 is a diagrammatic view illustrating a modified form of the invention.

Figure 9 is a sectional view taken substantially on the line 99 of Figure 8.

Referring now to the drawings, the numeral 10 designates a window frame as a whole, embodying a sill section 11, side jambs 12 and a header 13. The several sections are rigidly connected at their abutting ends any desirable manner, such as by angle brackets or the like '(not shown). The window frame is mounted and secured in the preformed wall or other opening in any conventional manner. The frame is preferably rolled, extruded or formed metal.

The sill, jambs and header are each of similar shape, comprising outer and

inner flanges

15 and 16 respectively, and a web member 17 connecting the flanges.

The closures for the window forming a preferred embodiment of this invention comprises an upper sash or ventilator 20, an intermediate fixed light 21 and a lower ventilator 22 operably connected to the upper ventilator as will be described in detail below.

The frames of the ventilators are constructed of the same type of sections as the window frame 10. Thus, the upper ventilator frame comprises upper and

lower members

25 and 24, and side members or stiles 26. Similarly, the lower ventilator frame comprises upper and

lower members

29 and 28, and side members or stiles 39. The fixed light 21 is comprised of the side jambs 12 and upper and lower

meeting rail members

33 and 32. It will thus be understood that a dummy or a fixed ventilator is not required.

Means are provided for operably connecting the ventilator 20 to the window frame, and as shown in the drawings, these means may include the sliding shoe assemblies 38 and balancing arms 39. It will be understood that the means for connecting each side of the ventilator to the respective jamb are identical, so only one will be described in detail.

Secured to the upper frame member 25 of the ventilator 29, by means of screw members 40 is an anchor block 42. The block extends outwardly from the end of the frame member and carries an integral stub shaft or pin 43. The web 17 of the jamb is provided with an upper vertical slot 44 through which extends the shaft 43. A stabilizer shoe 45 is journalled on the shaft and is urged into contact with the exterior side of the jamb web 17 by means of a helical spring 47, one end of which bears against the shoe. The other end of the spring bears against a crank or lever arm 49 which is rigidly connected to the end of the shaft 43, preferably by means of welding.

The balance arm 39 is pivotally connected at one end to the jamb web 17 by means of a pin 52, and similarly pivotally connected at the other end to the ventilator side member 26 by means of screw member 54 and washer 55.

From the description thus far it will be understood that the ventilator 20 is operably connected to the frame 10 for outward opening movement with respect thereto. That is, as the lower portion of the ventilator swings outwardly, the upper portion thereof moves vertically downwardly by virtue of the sliding connection between stood that by reason of the shoes 45 and springs 47, the

ventilator is centered and. stabilized through tension thereof. The lower, part'of the groove 44 isiwidened as at 60 to permit the shoe assembly to, be removed therethrough for service or repair During normal use; this widened portion 60 is covered by a plate -61, secured to theweb 17 by means of screw members '62,.vwhich plater functions as a stop and weathering member. 11

The lower ventilator '22 is connected to the window frame in'a manner identical to that described above with respect'to the upper ventilatorv 20. Thus, a balance arm 65 is pivotally connected to the lower portion of the jamb web 17 and to theside member 30, and a sliding shoe assembly 67 operates in a slotv 68 in'the web 17. A lever arm 69fis rigidly'connected to the stub shaft (not shown) of the shoe assembly 167. It will again be understood that the ventilatorfconnecting members are duplicated on each side thereof. The upper and

lower ventilators

20 and 22 are connected together for simultaneous operation by means of an adjustable link member 70 which is pivotally connected at the upper and lower ends thereof, by means of bolt members 71 and 72, to theflever arms 49 and 69 respectively. The bolt 72 extends through a vertical slot 73 in the lower end of the link member 70, thus providing a means of adjustment of the relative positions of the lever, arms 49 and 69, and inturn, the ventilators 20 and. 22. The linkage assembly, which comprises the link member 70 and the lever arms 49 and 69, is enclosed in a cover member 80 suitably supported on a bracket element 81..

The above-described structure, which permits the linkage assemblies to be located to the sides of the window frame, enables use of simple, individual inside screens 85 and 86 for the'ventilators. This structure also permits the omission of .any screening covering the fixed light 21. Preferably, the lower screen 86 is of the sliding wicket type to permit ready access to the ventilator 22.

In operation, by manipulating the lower ventilator 22, the upper ventilator 20 is simultaneously and similarly operated through the linkage assembly.

A modified formof the invention is diagrammatically illustrated in Figure 8. 7 Here again, the window includes an upper ventilator 100, a lower ventilator 101, and an intermediate fixed light 102. Here, however, the upper ventilator is mounted to move outwardly, while the lower ventilator is mounted to move inwardly. The upper ventilator 100 is identical to the ventilator 20 previously described, and is similarly connected to the jamb' 106, being provided with a sliding shoe assembly 103, balancing arm 104 and lever arm 105.

The lower ventilator 101, on the other hand, is pivotally connected to the jamb 106. As shown best in Figure 9, an anchor block 107 is secured to the lower frame member 108 of the ventilator 101 by means of screw members 109. The block extends outwardly from the end of the frame member and carries an integral stub shaft or pin 110. The web 111 of the jamb 106 is provided with a slot 112, which permits the block and its associated parts to be disassembled from the ventilator after installation. A cover'plate 113 secured to the web 111 normally covers the slot 112 and, additionally, is provided with an aperture 114 through which extends the pin 110, the cover plate thus further functioning as a pivot for the pin 110 and hence also the ventilator 101. Rigidly secured to theend of the pin, as by welding, is a lever am 115.

The upper and lower ventilators 100 and 101' are connected together for simultaneous operation by means of an adjustable link member 120 which is pivotally connected at the upper and lower ends thereof, by means of

bolt members

121 and 122, to the lever,

arms

105 and 115. The entire linkage assembly is preferably enclosed in a cover member (not shown).

It will be noted from an inspection of Figure 8 that when the ventilators are in the closed position, the lever arm 115 is inclined at an angle of about 30 from the horizontal, and further, that the arm .115 is approximately twice the length of the arm 105. This is to compensate for the fact that the upper ventilator 100 both pivots outwardly and slides downwardly in operation, whereas the lower ventilator 101 has only a pivotal motion. By means of the structure shown, both ventilators simultaneously open to the same extent.

It will be understood from the above description that V simple ,yet highly efiiective multiple operating awningwhich is entirely protected from the weather, paint and V the like.

By virtue of the same structure, the shoe assemblies and other moving parts maybe lubricatedwithout marn'ng the appearance of the'sash, and, if desired, the moving parts may be removed from the inside without any change in the building structure. It is also apparent that the operating or linkage assembly is especially adapted to be contained within a compact, unobstructive housing or cover. As has been pointed out, the structure permits the use of screening directly attached to the frame, and only where needed. Moreover, the described structure is so' designed as to eliminate the pos sibility of the ventilators falling'out of the frame upon failure or arm breakage and/or shoe failure.

While the invention has been described as applied'to only two simultaneously-operated ventilators, it will be readily apparent to those skilled in the art that more than two ventilators may be connected for multiple operation in the same manner. Also, if it is desired to open the ventilators inwardly, rather than outwardly, this may be accomplished by a simple reversal of the respective positions of the shoe assemblies and of the balance arms, with respect to the ventilators.

Having'fully described my invention, it is to be understood that I do not wish to be limited to'the details herein set forth, but my invention is of the full scope of the appended claims. I
