To all whom t may concern:

Be it known thatL'FRANn DUTCHER, a citizen of fthe United States, residing at Grottoes, in the county .of Rockingham yand State of Virginia, have invented certain new and useful Improvements in Windowv Constructions, of lwhich the following is a speci- ,provide hingedly connected sashes slidably Amounted at one of their ends in the window frame, and means operatively connecting and balancing the hinged s ashes and operating to sustain the same in their adjusted open positions.

It is also an important object of my invention to provide simple and effective operating means 'wherebyv a plurality of pairs of .hinged sashes may be easily operated in unison and moved totheir open or closed positions.

`It is a further general object ofthe inveiition to. improve the construction and .serviceability of windows whereby the desired .amount of ventilation may be obtained, the

window construction beingY comparatively simple, durable and capable of rmanufacture at relatively low cost. i i

With the above yand other objects in view, .my invention consistsin the novel features of construction, combination and arrangement of parts to be hereinafter more fully VAdescribed, claimedand illustrated in the accompanying drawings,in which,

Application filed August 30, 1916. Serial No. 117,675.

the mounting of the sliding ends of the winf dow sashes and Fig. 7 is a similar view illustrating a sheet metal, lire-proof construction of the window.

Referring more particularly to Figs. l and 2 of the drawings, 5 designates the frame of the window, the vertical side bars 6 of which are provided in their inner faces with the longitudinal channels 7 Within the lframe 5, the sashes are arranged in pairs. The sashes 8 in each pair are hingedly connected to each other at their opposed ends, as at 9. At the opposite ends of the top rail of the upper sash and the bottom rail of the lower sash in each pair, trunnions 10 are rigidly iXed in any preferred manner. In Fig. 6 of the drawings, I have illustrated one Convenient practical manner of mounting the sashes for relative sliding movement in the window frame. To this end, the metal blocks 11 are mounted in the channels 7 for free vertical movement, and

Veach of said blocks is formed With a bearing socket 12 tol receive one of the trun-v nions 10.y

In the top bar of .the frame 5, at each end thereof, a pulley or sheavel 13 is suitably mounted, and over the same a chain or cord 14 is trained. @ne end of this chain is suitably connected to the slide block 11 for the upper sash 8. The chains 14 extend downwardly and around and between the pair of guide pulleys 15 and have their lower ends attached to the slide-blocks 11 for thetrunnions of the lower sash 8 inthe upper pair of'sashes. The ychains 14 are entirely covered and hidden from view by the molding strips 16 ywhich* are secured to the inner facesl of the side bars of thev frame 5.

To the slidably mounted end of each of #the sashes 8 and preferably at each side of ...tareas-.l1 essaie@-aiittiesteiiliisttetls ...sedi-@serais their @lessi assisi-@neas 'ai-@W11 in Fig. 1, an outward pressure upon the hingedlyl connected ends of the sashes in the upper pair causes the chains 14 to pull the sliding end of the lower sash upwardly to the same extent as the sliding end of the upper sash moves downwardly in the window frame, and the tendency of the inner end of the upper sash to gravitate downwardly in *theV window frame iscounterbalanced by the weight of the lower sash. The corresponding sashes in the two pairs being connected by the bars 18, it is manifest that the sashes in the lower pair will also be moved to precisely the same relative angular relation as the sashes in the upper-pair. Thus, any desired amount of ventilation- 'may be obtained and the angular disposition of the'several sashes operates to direct the air currents into the room or apartment.

A In Fig. 3 of the drawing, I have illustrated a slightly different chain connection between the sashes, whereby the connecting bars 18 may be dispensed with. In this arrangement, the'chains 14 extend substantially the entire length of the window and have their upper ends attached to the slide blocks of the uppermost sash and their lower ends to the slide blocks of the lowermost sash. rIhe intermediate portions of the chains pass between the guide rollers or pulleys 15 which `are mounted substantially at the center of the window frame. The lower sash in the upper pair is connected tothe upper sash in the lower pair by means of the hinges 9', it being understood that these hingedly connected ends of f the ytwo pairs of sashes are not slidable in sashes in the upper pair.

the side bars of the window frame but are freely movable transversely with respect thereto. Thus, the four sashes may be disposed in various angularly adjusted positions or moved in unison vertically in the window frame and will be sustained in such adjusted positions by mean of thecounterbalancing chains 14. Y

Fig. 4 illustrates stillanother alternative arrangement of the operating connection between the window sashes wherein the corresponding sashes in each pair are connected at one side of the window by the bars 18",

and to the upper ends of the bars connecting the lower sashes, chains 14a are attached and extend upwardly around guide pulleys 13 mounted on the top bar of the window frame and lthen across to the opposite 'side of thetirely exposed, but it is manifest, of course, vthat inV practicethese parts may be suitably mounted inthe window frame or in-A closed within a suitable casing or housing fixed thereto. It is further to be borne in mind Y that while I have herein illustrated only two pairs of the relatively movable sashes, any

desired number of pairs may be used, the Y sash connections simply Vbeing multiplied.

The construction of the window as shown in Fig. 6, is quite similar to the usual construction of wood windows, but in Fig. 7 I have shown the manner of mounting the sliding sashes in a metal, fire-proof window construction, and it will be noted therein that y the verticalside of the window frame is constructed in two parts, each formed from a sheet metal plate. The main section 20 is bent to provide the vertical channel 7 in its inner wall, within which the slide block 11 is mounted to receive the pin or trunnion 10 on the sash 8. rlhek framev plate 2O is also bent to provide a vertical flange 21 at one side of the channel 7 andthe sheet metal plate from which the vertical:

stileof the window sash 8 is formed, is suitably bent to provide an oppositelyA projecting,`vertical flange 22 whichextends inwardlyV between the flange 21 and the inner side face of the frame plate20. V'Iheflange 22 in Fig. 8, and the corresponding part in Fig. 7, does not extend the entire length of the sash, but terminates short of the sash against the sash frame and prevent the free swinging movement of the sash. A longitudinally extending, sheet metal channel plate 23 projects inwardly from the wallof pivot so that said flange will not bindV the channel 7 and is suitably secured to the opposite sides thereof.` The spaced, intermediate portions of the guide channels 7 and the plate 23 provide a pocket vor chamber to receive the chain connection between the sashes. The edges of the body plate Q0 i on the sash frame are connected by the outer vertical side plate 25 by forming interlocking, longitudinal tongues on the edges of said plates and securely ,clenching the same y together.

AFrom the foregoing description, talien in connection with the accompanymgdrawings,

-the construction, manner of operationand several advantages of the illustrated embodiments of my invention will be clearly and fully understood. In practice, I have found that the construction and mounting of the sashes above referred to provide a very convenient and easily operated window whereby the adjustment of the sashes can be readily effected to secure the desired ventilation. The convenience of this arrange ment of the sashes whereby they can be disposed at various relative inclinations in Washing or cleaning the windows, is apparent. In the present application, no particular mounting and construction of the guide pulleys or wheels for the cord or chain connection is included, as this and other details of the invention I propose t0 later improve whereby a practical, eiicient and durable construction of such parts will be provided. It is, therefore, to be understood that in the commercial development of the invention, I contemplate making numerous mechanical changes of a minor character and I, therefore, reserve the privilege of adopting all such legitimate modiiications as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent is l l. The combination with a window frame, of a pair of sashes hingedly connected to each other at one of their ends, means for slidably mounting the other ends of the sashes in the window frame for relative vertical movement, an additional pair of relatively movable sashes, means operatively connecting each of the latter sashes to one of the first named sashes and permitting of the angular movement of all of said sashes with respect to each other, and counterbalancing means connected only to the rst named sashes to sustain the several sashes in their adjusted positions with respect to the frame.

2. The combination with a window frame, of upper and lower pairs of sashes operatively connected to each other for movement as a unit, the sashes in each pair being also hingedly connected to each other for relative angular adjustment, and counterbalancing means movable in the frame and operatively connected to certain of the sashes to sustain the sashes in their adjusted angular positions and also prevent their casual vertical move* ment with respect to the frame.

3. The combination with a window frame, of a plurality of pairs of window sashes, the sashes in each pair being hingedly connected to each other at one of their ends, means for slidably mounting the sashes at their other ends in the window frame for relative vertical movement, an operating connection between the corresponding sashes in the several pairs, and means for balancing said sashes and sustaining the same in their angularly adj ust-ed positions in the frame with respect to each other. f

In testimony whereof I hereunto affix my signature in the presence of two witnesses. FRANK DUTCHER.
