8 Claims.

The present invention relates to an awni type window consisting of a window frame and a plurality of sashes mounted so as to be tiltable outwardly for opening of the window. Windows of the awning type are not broadly new. My invention relates to certain improvements which are described in detail hereinafter.

There has long been a demand for a cord operated window which could be easily and quickly opened or closed, with little efiort and which would automatically lock itself in intermediate positions of adjustment. There has also been a demand for windows which could be operated without movement of Venetian or other blinds whichmay be associated with the window.

One of the primary objects of my invention is to provide an awning type window which is cord operated and which can be opened or closed rapidly and with a minimum of effort. Another object of my invention is to provide an awning type window which can be opened or closed without disturbing Venetian blinds, drapes, curtains or other window coverings. Another object of the invention is to provide a window of the awning type which automatically locks itself in any desired position of adjustment. Another object of the invention is to provide an awning type window having operating mechanism in which the initial opening movement of a window sash consists predominantly of tilting or pivotal movement of the sash about its upper edge, whereas subsequent opening movement of the sash consists predomlnantly of downward movement of the upper edge of the sash accompanied by pivotal movementof the sash about a horizontal axis intermediate its vertical length. Still another object of the invention is to provide an awning type window having hollow box-like jambs which house the opening and closing mechanism, and which have removable covers permitting access to the opening and closing mechanism for servicing or repair. Another object of the invention is to provide an awning type window in which theopening mechanism is positioned in the box jamb at one side of the window while the closing mechanism is positioned in the box jamb at the opposite side of the window.

The foregoing and other objects and advantages of the invention will be better understood by reference to the following description and the accompanying drawings, wherein:

Figure 16 is a transverse sectional view looking in the direction of the arrows along the line |6l 6 of Figure 4.

The window frame is designated generally by the reference numeral l8 and it includes a left box-like jamb 19 for housing the window opening mechanism, and a right box-like jamb 20 for housing the window closing mechanism.

The window frame l8 may be conveniently made v of metal and the entire window assembly may be sold as a unit for insertion in a window opening of a building. The outer flange 2| is of assistance in positioning and retaining the window assembly in a wall. The jamb' l9 preferably has a removable cover 22 to permit access to the opening mechanism, and the jamb 20 has a similar removable cover 23 to permit access to the closing mechanism. The sill of the frame is designated by the reference numeral 24 and the header by the reference numeral 25.

I have illustrated and described the invention as embodied in a window having two vertically spaced sashes, although it will be apparent that the invention is not limited to the use of two sashes. The upper and lower sashes are designated by the numerals 26 and 21, respectively.

The openingmechanism can be best understood by reference to Figures 3 to 6, inclusive. The upper corner of the upper sash 25 is pivotally secured by means of a bolt or rivet 28 to a head block 29. The head block 29 has secured thereto a stud 30, best shown in Figure 1]., WhiCh'iSS1idable in the guideway of a slide 3|. The upper corner of the sash 21 is pivotally secured by means of a bolt or rivet 32 to a head block 33 which is slidable along a slide 34. The head blocks 29 and 33 are rigidly connected by means of a head block connecting bar 35.

The lower sash 21 has pivotally-securedthereto at. fixed point 36a, the outer end of a stabilizer link 36, the inner end'of this link being pivotally connected to the jamb at 31.

A pivot arm 38 is'pivotally secured to the jamb 1:9 at '39. The outer long arm 46 of the pivot arm 38 is secured to'the side edge of the sash '25 for both pivotal and sliding movement relative thereto. The short inner arm 4| of the pivotarm 38 is angularly offset from the longer arm 59, as shown in the drawings. The short inner arm 4! is pivotally connected at 52 to the upper end of a pivot arm connecting bar 43. The lower end of thepivot arm connecting bar 43ispivotally secur'edat M to theshort inner arm45 of a pivot arm 56 which is pivotally secured "to the jamb Hi to $1. The longer outer arm d9 of the pivot armdfi is securedto the side edge of the sash 27 for both pivotal and sliding movement relative thereto.

As indicated above, the long arms 45 and'4'8 of the pivot arms 38 and 46, respectively, are secured tothe'side edges of the sashes 26 and 2? to permit both pivotal and sliding movement of the arms relative tothe sashes. The arm 45 of the pivot arm 38 is provided with a stud 49 which is slidable in the guideway of a slide 59 Which is best illustrated in Figures 12 and 13. The slide 59 is riveted or otherwise secured to the side edge of the sash 25. The outer end of arm 48 of the pivot arm 46 is provided with a similar stud 5! which is slidable in the-guideway of a slide 55 secured to the side edge of the sash 21.

A link cord 52 has one of its ends secured to thepivot arm connecting bar 43 by means of a suitable clip 53. The opposite end of the link cord 52 is connected to the head blockconnecting bar 35 by means of a clip 55. A floating pulley 55 is positioned on the link cord 52. An opening cord 55 is secured to the floating pulley 55. The opening cord extends downwardly around a lower stationary pulley 51, thence upwardly through the jamb [9, over an upper stationary pulley 58 and outwardly through a guide 59. The guide 59 positions the free end of the cord inwardly from the window so that a Venetian blind or other window covering will not interfere with access to the opening cord. In Figure 2 I have illustrated in dot-dash lines the header mechanism housing for a Venetian blind, such housing being designated by the reference numeral 69.

Figure 4 illustrates the window in closed position. The head blocks 29 and 33 are at their extreme upper limits of movement in their respective slides 3l and34. It will be noted that the free end of the opening cord 55.

slides 3| and 34 are inclined inwardly toward their upper ends, so that the upper ends of the sashes are drawn against the frame in the closed position. The stabilizer link 35 is approximately vertical and the short arms 4| and 45 of the pivot arms 93 and 46 are inclined approximately 30 above the horizontal. The studs 49 and 5i on the outer ends of the pivot arms 38 and 46 are at their extreme lower limit of'travel in the slides 50.

To open the window tension is applied to the This results in downward movement of the floating pulley 55.

The link cord 52 permits the head block connectingbar 35 and the pivot arm connecting bar 43 to move independently. The initial downward movement of thefloating pulley 55 will result predominantly in downward movement of the pivot arm connecting bar d3 with consequent pivotal movement of the pivot arms about their fi-xed pivotal axes 39 and 47. This pivotal movement of the pivot arms 33 and% will result in outward movement of the bottoms of the sashes 26 -and21. During this initial movement, the sashes26 and 2'1 pivot about their respective head'blo'cks29 and 33. Figure 5 illustrates the positions of the several elements after initial downward movement of the floating pulley 55. 'Itwillbe seen' that'the short inner arms ll and45ofthe pivotar'ms are now inclined approximately30 below the horizontal. The window sashesv have'been openedlto the extent illustrated. The'headblocks'29 and 33 have moved downwardly in their respective slides by only aumued extent. Further pulling on the opening cord 56 results in further downward movement of'the floating pulley '55 with consequent further opening of the sashes. ""Iheiposition of the elementsafter further openingof the sashes is illustrated in Figure 6. This further opening has resulted predominantly from downward movement of the upper edges of the sashes and their respective head blocks. It will be seen that the head blocks 29 and33-have movedto approximately the lowerlimit of their :travel'in their'respective slides 3| and 34. Thestabilizer link 35 occupies the position shown in Figure 6, and the studs 49 and 5| 'in the outer ends of the pivot arms have moved to approximately their upper limits of travel-in theslidesiii.

The closing mechanism-shown in Figures 7 and 8 is similar to the opening mechanism, andfor that reason the same reference --numerals are applied to corresponding elements. The closing mechanism is housed within the box-like ja'mb 29. The sashES-ispivotally secured to the head block "29 and the sash '21 is pivotally secured to the head block 33. The head blocks 29 and- 33 are rigidly secured to" each other bymeans of a head block connecting bar 35. The pivot arms3'8 and ii) are identical-'to'the comparable members described aboveandthey are joined by a pivot arm connecting bar 55. A stabilizer bar 36 is provided which holds the sashes 25 and 2'! in any desired position of adjustment'in spite ofgusts of wind or other forces Whichmay'be applied to them. The head block "29 is slidableina'slide 3! while the head b'lock'fifi is slidable in a slide 35. A link cord ti has oneof its'endssecured to the'head block connecting bar "35 while its opposite'end is connected to the pivotarm'connecting bar 43. "A floating pulley 52'is'poSitioned on the link cord 5 l. A closing cord 63 is secured to the floating pulley 52. 'This closing cord extends upwardly over a stationarypulleyfi l and through. v.a guide 65 similar to the guide. 59

described above.

When tension is applied to the closing cord 63, the floating pulley 62 will be elevated. The initial effect on the sashes is demonstrated by a comparison of Figures 7 and 8. The predominant movement during the initial closing operation will be upward movement of the upper ends of the sashes and their associated head blocks 29 and 33. .Further upward movement of the floating pulley 62 will cause the head blocks 29 and 33 to move slightly to their extreme upper limits of movement, but the predominant effects of such further upward movement of the floating pulley 62 will beupward movement of the pivot arm connecting bar 43, pivotal movement of the pivot arms 38 and 45 about their pivotal axes 39 and, and inward pivotal movement of the sashes. 28 and 21 about their respective head blocks. It will be seen that such closing movement can continue until the sashes are completely closed. It can also be seen that the closing movement is essentially the reverse of the opening movement described above.

I prefer to provide a latch 66 in the window sill 24 for the purpose of latching the lower sash 2?. Thislatch is bestillustrated in Figure 14. The hook 67 is pivotally connected at B8 to brackets 69 which are secured to the inner surface of the sill .24. v.The hook 61 may enter an opening in thesash 21 and engage a shoulder 10 to prevent opening of the lower sash 21 and consequently to prevent opening of the upper sash. The hook Sloan bemoved from the full line position shown in Figure 14 to the dotted line position to permit opening of the window.

I have found that the opening and closing mechanism which I have illustrated and described is particularly effectivefor use with windows of the easement type. The fact that the initial opening movement of the window is predominantly an outward swinging motion of the bottoms of the sashes and the factthat the further .opening movement is predominantly a downward movement of the upper ends of the sashes are essential in obtaining smooth operation with little effort on the part of the operator. The reverse operation in closing the windows also contributes to facility of operation. The use of the link cords 52 and GI and the floating pulleys 55 and 62 make these two types of movement possible since these elements permit independent relative movement of the head block connecting bar 35 and the pivot arm connecting bar 43.

I have referred to certain of the elements herein as cords, but it will be apparent that other suitable flexible elements can be used, and the term cords is intended to be generic to equivalent elements.

I have illustrated and described what I now consider to be the preferred embodiment of my invention, but it will be understood that various alterations and modifications may be resorted to without departing from the broader scope of my invention as defined by the following claims.
