Application June 14, 1957, Serial No. 665,722

Claims. (Cl. 2042) The present invention relates to window construction and has for its main object the provision of means whereby two window sashes may remain upon the same providing ventilation, and whereby the two window sashes may be brought to a horizontal position to permit access to the outer faces of the Window panes for cleaning or washing the same.

Still another object of the present invention is the provision of a suitable mechanism whereby one of the window. sashes may be bodily shifted inwardly of the dwelling and brought within a plane removed from the plane of the other window sash, and whereby the first of said window sashes may be shifted in a vertical direction upon the plane which is removed from the plane of the other window sash.

Still another object of the present invention is the provision of means whereby a window sash, when angularly shifted out of a window opening, may be maintained in its angular adjusted position;

A still further object of the present invention is the I provision of novel means for guiding the upright shifting movement of a window sash bodily within a window opening, irrespective as to whether the window sash has been angularly shifted within a dwelling or whether the same is in its normal closed position within a window opening.

A still further object of the present invention is to generally improve a window construction, including a window frame and a window sash of the type capable of angular adjustment within the window frame and capable of upright shifting movement within the window frame either during its normal closed position or its angular adjusted position.

With the above general objects in view and others that will appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views;

Fig. 7 is an edge elevational view of the two window sashes, illustrating the position of the lower sash when shifted inwardly of the dwelling to a plane removed from the plane of the upper sash, further illustrating the mechanism whereby the lower window sash may be shifted to the position stated as well as to the angular position thereof;

Fig. 8 is a similar view as that shown in Fig. 7 of the lower window sash, illustrating the angular position of the lower window sash with the mechanism for supporting said window sash in that position;

Fig. 9 is a fragmentary face elevational view of the lower window sash with the mechanism whereby the said window sash may be shifted and supported in its positions shown in Figs. 7. and 8, the View having been taken substantially upon a plane indicated by line 9-9 of Fig. 7; and

Fig. 10 is a perspective view of a portion of the mechanism whereby the lower window sash may be shifted to the various positions above indicated and illustrated in Figs. 4, 7 and 8, and whereby the same may be maintained in those positions.

Referring in detail to the present drawings there is shown therein a window frame which includes vertical frame side members 11, lower horizontal frame member 12 and upper horizontal frame member 13. Inner window sill 14 is rigidly supported upon said lower horito the inner faces of said vertical frame side members 11 are molding strips 19, which are in a spaced relation with the oppositely disposed inner faces of said frame bars 17. Afiixed to the inner face of each of said molding strips 19 is weather strip 20, including an inwardly directed extension 21.

Fitted within the window frame as hereinabove defined is a lower window sash, which includes a lower horizontal sash bar 22, upper horizontal sash bar 23 and a pair of vertical sash bars 24, said bars being arranged in a frame for maintaining therewithin window pane 25.

The upper window sash includesa lower horizontal sash bar 26, anupper horizontal sash bar 27 and a pair of vertical sash bars 28, said bars being arranged in a frame for maintaining therewithin window pane 29.

The upper horizontal bar 23 of the lower sash and the lower horizontal bar 26 of the upper sash are suitably molded to define scarf joint 30, so formed however that when the two sashes are in a mutually closed relation within the window frame, as seen in Fig. 2, the upper window sash cannot be moved either vertically or angularly until the lower sash by its upper portion has f Felt weather-strip '31, 'is aflixed to the inwardly dis:

P951114; c of mq'ld ri 1 d s n rp se therebctween the vertical sash bars '24 and 28' of the two windowsashes, as, best seen in Figs. 3 and 6 for preventing dust andhw'ind from entering'the dwelling'when the two sashes remain in a closed position within the window frame. t

- ferried-upon the inner face of each vertical sash bar 24 and-'28 of-the two window sashesis molding strip plate 32, which by its inner free edge, which defines lip 33', overl-aps-and-engages extension 21 of said weather strip 20, as is best seen in' Fig. 6-. Thus, 'when the two window sashes are -in a closedposition within the window frame, extensional-and lip '33- are in a mutually contacting relation for providing a seahfor-preventing dust or wind from entering a dwelling; l

' Itis further observed that when-the two sashes are in a mutualvertical a-linement, as seen in 'Fig, 2; the'lower horizontal bar 22 of the lower window sash remains in eont-act wi th the outer edg elof the window sill'14, while the upper horizontalf'bar 27 of the upper 'sash remains within'recess-lo of board 15. I j j Each of the vertical sash,

bars

24 and 28 of the .two window-sashes remain spaced from each vertical frame side member 1 1, asbest seen in Fig. 6, and in conjunction withframebars 1'7- and molding strips 19 define oblong vertical jhousings 34;, one adjacent each of said" vertical framcside-mernbers 11, extending along the entire height of the window frame, as best seen in Figs. 3 and 6.;

Positioned within each housing 34' and rigidly secured by their ends to the lower and upper horizontal frame members-Hand 13, is a pair of rods '35. With relation to-theinside of the dwelling a pair of opposed rods 35 which are farthest removed from the dwelling, or. more specifically those which are nearest to frame bars 17, will be hereinafter referred to as outerrods 35, while a pair of opposed rods -35'which are nearest to the dwelling, or more specifically those which are adjacent molding strips 19, 'will be hereinafter referred toast-he inner rods 35. Afiixed to eachof the side edges of the vertical sash bars 28 oftheupper window sash, by'means of a plurality of screws 36, andadjacent the lower' end thereof, is plate '37-, Positionedupon-cachet said 'outer rods 35 yfor'upright sliding thereonis a-lower sleeve 38 and an upper sleeve 39; Extending from the-'l-'ower end of the lower sleeve 3.8,in the direction of each of said vertical sash bars 28, is'pin 40 whichenters an aperture provided in the lower end of each plate 37, and-thereby forms-a pivot for the lower most end ofthe upper window sash, uponWhichthe-latter may angularly swing'as is seen in Fig. 4. As an alternative construction of the said pivot, shown in Fig. 5, rod

'41 is made to extend-through the entire length of the lower 'horizontal sash bar 26 and through the-two plates 37, and enter, by its ends an enlargement 42- made atthe lower .endof each sleeve 38, and thereby form a pivot upon which the upper window sash-may angularly. swing inwardly f the. dwelling, as shown .in Big. 4. T

Ooactingwith'each' side of the upper window sash is arm:,43, which by its lower end is pivotal'ly .affixed, .as at 44, to plate 37:, at a point substantially centrally ofthe latter, and by itsoupper endzis pivotallysconnected, as at 45,10 sleeve .39., adjacent the lower end thereof.

Assuming that the lower window :sash. :is angularly shifted out'of the window .openihgand otherwise out. of thepa th of: the upper. window sash, the conditions which willbe. later apparent, the. upper: window sash; is capable fiangularly shifting :Within the dwellingfrom the window open n f n of assuming various angular positions; from almostventical position. to. the ;horizontal-position,-; the latterbest shownin: Bi ;:4.. When in thatilatterpo t the outer face of the window pane 29 will become exposed withinthe dwelling thereby permitting ready access thereto for the purpose of washing the same. One of the intermediate positions of the upper window sash between vertical and horizontal is indicated by dotted lines in Fig. 4. When in one of said intermediate positions the opening of the Window will provide ventilation.

Regardless as to what extent the upper window sash' is angularly shifted fromw-ithin the window opening the former moves upon its

pivot

40 or 41. "When the upper window sash remainsfin'a horizontal position arm 43 shifts to an angular position both with relation to the upper sash and to the upper sleeve 39 as is seen in Fig. 4. Since said upper sleeve 39 is capable of shifting :upon each of outer rods 35 to or away from the lower sleeve 38, the two sleeves remain in a spaced mutual relation, as is seen in Fig. 5, with arm 43 remaining in a vertical position when the upper window sash is-within the window opening. When however the upper window sash'has beenangu'larly shifted to the horiz n 'po ion, s o in F s-v ia-upper sleevej3'9 by its lower end comes incontac't with the npper end of lower sleeve .3 8, and the latteracts as a stop for preventing farther angular shifting of the. upper window sash'beyond' the horizontal plane.

When thelower window sash has been angularly shifted it is possible for the .upper window sash to shift downwardl y and within the confines of the lower. portion ofthe window opening, the outer rods 35 guiding sleeves '38 and 39 in' their shifting movement.

Referring to the mechanismfor angularly shiftingi the lower window sash within. the window openinggpositions best shown in Figs. 4'and8, as well as for'bodily moving the lower window sash away from the plane ofithe'upper window sash, position best shown inFig 7; thesame in: cludes a pair of lower sleeves 46. and a pair of upper sleeves 47'positioned' for upright sliding movementmpon V inner rods 35. V

An 'L-shaped' member, generally indicated by 48 in Fig;

7 ,1 0, fitted upon each of the two lower edge corners oftlie y d sthe hor o ta lower sash, includ'es side plate 49, afiixed by a'plurality of screws 50 to each side edge of vertical sash bars 24., and bottom plate 51 afiixed to each end; ofthe'loweredge of the lower horizontal sash bar 2 2 by means of screws which pass through apertures 52. The lower end of plate 49"has an extension 53. directed toward a dwelling, with an xar= cuate recess 54, opening upon the outer edge of said plate 49 and entering saidextension 53.

The ends of the lower; horizontal sash bar 22' are-filed away from the continuing side edges of the vertical sash bars24, for defining, 1n conjunction with the lower end' of each plate 49 a recess 55, for accommodating therewithin link 56, which, by its upper end is pivoted upon -pin"57 mounted upon plate 49 and extending inwardly of recess 55 --adjacent theupper end of the latter. a f e Each of saidlower sleeves 46, ad'acent-its lower end; is provided with'a rigidly affixed pin 58, which extends toward the-lower window'sash, ina transverse :relationwith and past said plate 49; z v

Coacting with each side edge-ofthe lower windowsash is 59-, which by itsflower end'is. pivoted to the outer faceof-plate 49, substantially central-ly'thereof, 'by means of pin '60. By itsupperend-said arm-59 is. p ivoted'itmthe lower end of: the' uppersleeve 47; upon pin 61.

When the lowerwindow sash remains within the window opening or when the same is anguilarly Shiftfid,;jl1 either ofthose-cases pinr5firemains within the .closed: end of recessv or :sloti4, pins. :58: constituting. the supporting pivot or fulcrum for the sashm'hile in those positions,;;as seeninFigs. 4 andlSr. Whentherlower-window sash has been; shifted to. the horizontalposition, as seen Big; 4,.lowerzcnds of upper sleevessdfl coming in contact'wtith the upper: ends oflowersleeves-AG, prevent further downward shifting movement of the lower windowsash bew n ane- .WheirieMvs sash is shifted angularly from horizontal; tgwalfdfi the window opening, then arms 59 shift the upper sleeves 47 away from the lower sleeves 46, as is seen in Fig. 8. When the lower window sash is within the window opening in closed position, arms 59 remain in a vertical position and in parallelism with inner rods 35,

sleeves

46 and 47, and vertical sash bars 24. Similarly as was already described in connection with the upper window sash, when the lower window sash is brought to its horizontal shifted position, shown in Fig. 4, the outer face of the window pane 25 will be exposed within the dwelling permitting access thereto for the purpose of washing or cleaning. The lower window sash is capable of assuming various angular positions from vertical closed position to the horizontal position, as is seen in Figs. 4 and 8. No matter what particular angular position, from the vertical closed position, the lower window sash assumes, it is capable of bodily shifting in a vertical direction as is clearly indicated in Figs. 4 and 8, being guided in its bodily vertical shifting movement by the inner pair of rods 35 and

sleeves

46 and 47.

Arms 59 support the lower window sash in its angular adjusted position.

It is also noted that when the lower window sash is in a horizontal position pin 58 does not extend to the closed end of recess 54, but remains substantially centrally thereof, as is seen in Fig. 4. It is also noted that when the lower window sash is in a closed position within the window opening, the same is pushed in the direction away from the dwelling, until said lower window sash is on a common plane with the upper window sash, with the lower horizontal sash bar 26 of the upper window sash interconnected with the upper horizontal sash bar 23 of the lower window sash, through joint 30, as is seen in Fig. 2. In that closed position of the lower window sash pins 58 will find themselves within the closed ends of slots 54, as is seen on reference to the showing in Fig. 8. In that closed position of the lower window sash Within the window opening arms 59 will not be on a vertical line, but their lower ends will be on a plane toward the outside of the dwelling, with the upper ends of said arms 59' on a plane nearer to the dwelling, position substantially opposite from that shown in Fig. 7.

To bodily shift the lower window sash to the plane away from that of the upper window sash, first the upper end of the lower window sash is shifted within the dwelling, for bringing the lower window sash to an angular position. Thereupon the lower window sash while inthat angular position is bodily shifted in an upward direc tion until the lower horizontal sash bar 22 clears sill 14. When this has been accomplished the lower end of the lower sash is shifted inwardly of the dwelling. This latter operation causes link 56 to angularly shift and assume the position out of recess 55, as is seen in Fig. 7. Bodily shifting of the lower portion of the lower window sash moves the lower end of the lower window sash away from pins 58 so that said pins 58 remain out of slots 54, as is seen in Fig. 7.

When the above several steps have. taken place the lower window sash will be moved out of the plane of the upper window sash, with the lower window sash bodily shifted within the dwelling, as is seen in Fig. 7, ready to be shifted in an upward direction to assume an alined position on a horizontal plane with the upper window sash, thereby completely clearing the lower portion of the window opening.

Obviously, arms 59 must shift in the upright direction when the lower window sash is bodily shifted upon the plane removed from the plane of the upper window sash.

Were the molding strip plates 32 rigid with the vertical sash bars 28 of the upper window sash, arms 59 while shifting in an upward direction would encounter said molding strip plates 32 coacting with the upper window sash. To obviate the obstacle suitable mechanism is provided for causing said molding strip plates 32 at the upper window sash to shift away from the vertical frame side members 11, thereby providing clearance between extensions 21 and lips 33 for said arms 59 to shift there-; between in their upward shifting movement.

The lower corner portions of said lips 33 are filed away as at 62 for permitting entrance of said arms 59 past said lips 33 and extensions 21, at the inception of the upward shifting movement of said arms 53 as they are brought oppositely of the ends of the lower horizontal sash bar 26 of the upper window sash. This contact of arms 59 with the filed away'portions 62 .of lips 33 will cause molding strip plates 32 at the upper window sash to bodily shift away from the vertical frame side members 11, 'or more specifically from their contactual engagement with extensions 21. The mechanism for bodily shifting molding strip plates 32 and lips 33 away from weather strips 20 and extension 21, includes transverse slots 63 one adjacent each end of the portion of the molding strip plate 32 which remains in the immediate contact with the inner face of each vertical sash bar 28 of the upper window sash.

Washer 64 overlies the body portion of the molding strip plate 32 which is in contact with the inner face of each vertical sash bar 28, including the slot 63. Screw 65 is passed through washer 64 and is driven into the vertical sash bar 28. By virtue of this construction screws 65 constitute guides upon which each molding strip plate 32 is capable of bodily shifting to or away from vertical frame side members 11. For normally maintaining the molding strip plates 32 shifted toward the vertical frame side members 11 with lips 33 normally in a contactual engagement with extensions 21, a pair of resilient wires 66 is provided, one adjacent each end of the portion of each molding strip plate 32 which contacts with the inner face of the vertical sash bar 28. One end of each wire 66 is driven into the vertical sash bar 28, or is otherwise rigidly aifixed thereto, as at 67. The opposite end of each wire 66 is soldered or otherwise afiixed to the underface of the portion of each molding strip plate 32 which overlies the vertical sash bar 28, as at 68. Normally said wires 66 due to their inherent resilient nature, tend to urge said molding strip plates 32 and their lips 33 toward the vertical frame side members 11 with lips 33 in contactual relation with extensions .21, as best seen in Fig. 6. When however under the actuation of arms 59 as the latter pass past the filed away corners 62 of said lips 33, the latter as well as the molding strip plates 32 are caused to shift away from the vertical frame side members 11 and against the tensioning action of wires 66, thereby shifting said lips 33 away from their contactual relation with extensions 21 effecting a slot between said lips 33 and extensions 21 of a width suificient for said arms to enter and thereby to permit the unobstructed upright shifting movement of said arms 59 as the lower window sash is bodily shifted upon the plane removed from the plane of the upper window sash.

To accommodate said wires '66 the body portions of said vertical sash bars 28 are scooped or hollowedas at 69. In Fig. 1 portions of said molding strip plates 32 are broken away to illustrate depressions 69, wires 66 and the connections of the latter with the vertical sash bars 28 and said molding strip plates 32.

When the lower window sash has been moved in a downward direction and away from its alinement on a horizontal plane with the upper window sash, and once said arms 59 have cleared lips 33, the molding strip plates 32, by virtue of the action of wires 66, assume their normal closed position, shifted toward the vertical frame side members 11, with lips 33 in a reestablished contactual closed relation with extensions 21 as seen in Fig. 6.

From the hereinabove description it will be apparent that when the lower window sash remains in a horizontal position the upper window sash may be shifted downwardly and oppositely to the lower portion of the window opening, and as far as arms 59 will permit. Thus, either 7 sir-w ndow sashes when in ahorizontal position may ez'shi tedi re rhe d rec nto a p d e m ne position in order to have :a convenient 'accessto wash-t e outer Eachspringflt) is disposedintermediately of rods 35 and.

located-within each housing 34. The upper end of each spring 70 is attired to the upper horizontal frame member 13., :as at :Each spring 7 1 is located forwardly of each inner rod 35,,within-each housing 34, and substantially intermediately ofeach inner rod and each molding strip 19. The

upper end of each spring 71 is ailixed to the upper horizontal frame member 13.

Rigidlyaflixed to each upper sleeve 39 is bar 73, and rigidly affixed to, each of said upper sleeves 47 -is bar 74'. Said bars 721' and 74. by their opposite lower ends are at timesxin :a frictional contract with the lower sleeves 38 I and; 46, respectively, irrespective as to whether or not uppersleeves39 :and 47 are in contact by their lower ends with the :upper ends ofthe

lower sleeves

38 and 46, respectively, as seen in'Fi-g'. 4, or whether said upper sleeves are inuazspaced relation from said lower sleeves,as is seen inFig. 5-. ESaidbars73, and 74 are of a resilient nature for the purposeof exerting a comparatively strong frictional: contact upon said lowertsleeves' 38 and 46, respectively, and consequently for the purpose of engenderizng-rfriction between said sleeves 38 and the outer pair of r:cxis 35 as well .as between said sleeves 46 and the inner nodsSS.

integrally formedwith :and laterally projecting from each bar. 73 and 74. are

lugs

73 and 74, respectively, to whiohthe lower ends of. springs 70 and 71, respectively, are affixed.

By virtue of the friction aforesaid there is a bra-king action between sleeves 38 :and 46 and their respective outer :and ,inner'mds 35. This braking action prevents window sashes from shifting in the upward direction unlessmanual pressure is imparted to the sashes in order tonovercome the said friction and the braking action between :the said lower sleeves and rods 35.

lnlieu of springs 70 and T71 usual cords may be a-iiixed to. lugs and. 74; to be actuated by the conventional weights Whether springs or cords are used, in either event the braking action between the lower sleeves and:

their coacting rods willbe maintained for the purpose hereinabove specified. I

Latching devices 75. (Fig. l) are .aflixed to the upper horizontal sash bar 23 and the lower horizontal sash bar 26, of the lower and upper window sashes, respectively, whereby the two sashes may be locked when the same remain in .a-.closed'positionwithin the window opening, as is seen in Fig. 2.

Ring 76 may be affixed to the upper horizontal sash'bar 2-3 of the lower sash whereby said sash may be manually pulled from its closed position shown in Fig. 2 for angularly' shifting the same.

Carried by the lower ends of molding strip plates 32 is a pair of spacers 77, best shown in Figs. 1 and 2, which preventcontact ofthe lower window sash with the upper window sash when the lower window sash has been brought out of the plane of the upper window sash when the same is upwardly shifted, as is seen in Fig; 7', thereby preventing marringof the two window sashes which would ensue if the sashes were in :a frictional contact.

it is also noted that when the lower windowv sash is in a closed position within the window opening, and in aline-v ment 'ona vertical plane-with thesupper windowposition best shown in Fig. 2,, extension 53;, with platesandjSl, will remaininanz-outwardly shifted positionvvvgnh" relation to thedwelling, thereby causing Pil :8 to withinthe closed end ofrecess 541as is seen'in .Fig fii;

From the hereinabove description it will he, apparent that said links 56 and pins 58, inconj-unction'witlr tensions 53 and recesses 54, define a flexible hinge.eon,- nection'bet-ween the lower window sash. and-.';the lower sleeves 46, permitting said lowerwi-ndow sashntonaher na-tely assume a closed co-planar relation with the window sash, as is shown in Fig, 2, or anoutwardly shifted position upon a plane removed from theeommon verti'cle plane with theupper window 82181338 15 seen-'im Fig. 7.- a i From .the hereinabove description -it will also be rapparent that in additionto the function of bars-735 and 74', already described, the said bars bearingg against-thelower sleeves 38; and 46, respectively, tend topreventthe down,- ward sliding movement of the upper sleeves 39- .and 47",, respectively, toward'the cooperating lower sleeves 3 8=and 46, respectively, and thereby tend-to maintainone'or the other window sash in its angularly adiustedposition, in dicated by dotted lines in Fig, 4, or by'f-ulllines. shown in, Fig. 8.; Such angularly adjusted position of the-window sash will be maintainedby the actionof; one or the other of the said bars 73- :and 74- untilzmanu-al pre ssureis applied a gai-nst the window sash to alter itsangularposition against the action of either of the said: bars 73. and 74'.. Thus, said bars 73 and 74' have av double function, namely, they counteract the action of springs ,and- 71 .to. maintain the sashes in their vertical adjusted position within the window, and secondly, they maintain. the win dow sashes in. their angularly adjusted-position-within thewi-ndow, other than the horizontal. position, because in that latter position the sashes are maintained by virtueof the upper sleeves having come in contact with, the lQWer sleeves. V l v While there are described herein preferred, embod'h ments ofthe present invention, itis nevertheless to; be understood that minor changes may be made therein; without departing from the spirit and scope of the invens tion as claimed. a
