Claims.

This invention relates to a window construction and more particularly to a double hung window in which the upper and lower sashes, in addition to being movable vertically, may also be swung inwardly similar to a easement window, but which construction has advantages over a easement window.

It is an object of this invention to provide a novel window construction in which the parts are weather-tight, wherein the sash is readily movable vertically and yet may also be swung inwardly to permit Washing, cleaning or painting of the sashes and the Window panes carried thereby.

Another object of the invention is to provide novel guide means for the sashes during their Vertical movement, a portion of which guide means readily permits pivotal movement of the sashes.

A further object is to provide a combination double hung and easement window construction which may be easily and economically manufactured and installed, and in which the parts will require a minimum of replacement.

A further object is to provide a window construction of the character referred to with which a storm window or screen may be readily used, while permitting access to the storm window or screen from inside a house in which the construction is installed.

Still another object of the invention is to provide a window that can easily be adjusted in its mounting to tighten or ret same without removal of any fixed stops or balance means.

Another object is to provide a balance for a window wherein the balance means are completely concealed at all times regardless of the position of the window.

A further object is to facilitate the positioning of storm windows or screens from the inside of irregularly sized double hung windows, such as Oriel windows.

Yet another object is to provide double hung windows with a uniform glass line and with at least 90 degrees inward swinging movement when the windows are superimposed.

Another object of the invention is to provide an uncomplicated window construction wherein the window is pivotally but tightly mounted at one edge and adapted for vertical movement therealeng while the window also can be easily secured ina tightly closed position when desired.

Another object is to provide a double hung window with tracks for vertical movement thereon but from which one edge of each window can be sprung when at predetermined release points.

Yet another object of the invention is to provide a novel double hung window wherein storm sash associated therewith may be removed by swinging the windows inwardly, or by raising or lowering the sash vertically.

Another object is to provide a window construction having all advantages of a double hung window and more advantages than a easement window in that the Window can be selectively vertically positioned, and be swung inwardly at any desired Vertical position.

A further object is to balance either the top or bottom sash in an open position at any desired vertical height for the convenience of a person washing or painting the window.

Another object is to provide a double hung window which can be adjusted to provide full exposure of the entire window opening for ventilation or other purposes.

A further object is to provide a window sash with tracks for controlling its position and permitting vertical movement thereon but from which one edge of the sash can be released when at predetermined release points.

Yet another object of the invention is to retain a window sash of the class referred to normally in complete engagement with its guide tracks even when at its release position, and to facilitate engagement and disengagement of the window sash and tracks.

Other objects and advantages will become apparent from the following description taken in conjunction with the accompanying drawings.

For a better understanding of the invention, reference should be had to the accompanying drawings, wherein:

Fig. 9 is an enlarged fragmentary section taken substantially on line 9-9 of Fig. 8,

Fig. 10 is a similar section taken substantially on line Ill-I8 of Fig. 8,

Fig. 11 is a view similar to Fig. 8 with both sashes swung inwardly.

Fig. 12 is an elevation of a modication of the invention;

Fig. 13 is a cross setcion on line I3|3 of Fig. 12; and

Fig. 14 is an enlarged section of a portion of the structure of Fig. 13.

Referring to the drawings, the numeral I designates a top window frame member suitably connetced to side frame members and I2, the lower ends of which are suitably secured to the customary sill I3, under which the usual molding I4 may be provided.

As will be noted from Fig. 2, the sill I3 preferably has a portion I which may be integral therewith, that extends through the outer sheeting I6 of the dwelling in which the window is mounted and may rest on one of the suppotring elements of the dwelling, such as a 2 by 4, I1. The portion I5 of the sill tapers as at |8 throughout the greater portion of its width and has an increased taper at I9, the purpose of which will be explained hereinafter. Adjacent the lower edge of the top frame member IU, a horizontal supporting member 20 is suitably secured and the latter is also suitably secured to the outer sheeting I6.

A vertical support 2| (see Fig. 4, 6, `8 and ll) extends from the member 20 downwardly to the sill and is secured at its front end to frame member I I adjacent the inner edge of the latter, while its rear end is secured to a ller member 22 which in turn is secured to the wall sheeting I6. A similar support 23 is secured between frame member I2 and a second ller member |22, and extends between the sill and support 2U.

Secured to the inner faces of support 2| and filler members 22 and |22 is a vertical frame member 24 that extends from the sill to the support 20. Member 24 is generally substantially rectangular in cross-section with a portion cut out and rounded as indicated at 25. A vertical frame member 26, similar in cross-section and length to member 24, is secured to support 23 and filler |22, and has a portion cut out and rounded as at 21.

Co-operating with

frame members

24 and 26 for both vertical and swinging movement with respect thereto, is an upper sash member, indicated as a whole by the numeral 28, having upper and

lower rails

29 and 35, and side rails 3| and 32, all of which enclose va pane of glass 33. As shown, a channeled guide and hinge member 34, generally arcuate in cross-section, extends from the sill to the support 20 and has a flattened p0rtion 35 usually secured to and embedded in the front face of frame member 24, being secured to the latter by counter-sunk screws 36, or the like. Any suitable guide and hinge member, such as a pair of vertically spaced guide and hinge elements 31, is secured to the side rail 3| adjacent the upper and lower ends of the latter. Elements 31 are generally annular in cross-section and have Ka flattened extension 38 which usually is embedded in the side face of rail 3| that is adjacent to the frame member 24, being secured plementary to and co-operates with the rounded portion 25 of the frame member 24 to assist in providing a seal when the upper sash member 28 is in its closed position, as indicated in Figs. 4 and 8. The Iarrangement is such that the hinge elements 31 fit within the channeled member 34 and may either slide vertically or pivot therein, so that the upper sash may be moved vertically or swung inwardly from its closed position and then outwardly to its closed position.

Suitable lock means, which also may provide a guide for the opposite side rail 32, are provided for thev upper sash member 28. These means may include a channeled guide member 4|, also generally arcuate in cross-section like the member 34, that extends from the sill to the support 28 and has a attened portion 42 usually embedded in the front face of the frame member 26, being secured to the latter by countersunk screws 43, or the like. In its lower portion, guide member 4| is provided with one or more, in this instance two elongated spaced openings 44, which open to the front of the member 4| or toward the interior of the dwelling. A pair of guide and locking elements 45 are secured to spaced portions of the side rail 32 adjacent the upper and lower ends of the latter. The spacing of the elements 45 is equal to the spacing of the openings 44, but the latter are slightly longer than the elements 45. Locking elements 45 are generally annular in cross-section with their ends tapered inwardly for streamlining, and have a flattened extension 46 (Fig. 5) which usually is embedded in the side face of rail 32 that is adjacent to the frame member 26, being fastened to rail 32 by counter-sunk screws 41, or the like. Rail 32 has a rounded portion 48 that co-operates with the rounded portion 25 of frame member 26 to assist in providing a seal when the upper sash member 28 is in its closed position. The arrangement is such that the locking elements 45 t within the channeled member 4| and may slide vertically therein, but when the elements 45 are in alignment with the openings' 44, these elements may be swung inwardly out of engagement with guide member 4| by which movement the upper sash member also is moved pivotally about the guide 34.

Thus, the upper sash 28 may be moved vertically of the window frame with the hinge elements 31 and the locking elements 45 acting as guides within the channeled members 34 and 4|, respectively, while this sash may be swung inwardly only when in a lowered position with the locking elements 45 in alignment with the openings 44. However, once released, the sash 28 may be moved to any desired vertical position and still be swung approximately from its closed position.

Inwardly of frame member 24 and secured to the front face thereof so as to cover the attened portion 35 of channeled member 34, usually there is a vertical spacing member 49 that extends from the sill to the support 20. Member 49 may also be secured to support 2| and is preferably of a thickness about equal .to the outside diameter of channeled member 34. Secured to the inner faces of support 2| and spacer 49 is a smaller width vertical frame 50, extending from the sill to the top support 20, being generally rectangular in cross-section except that it is cut out and rounded as at 5|.

Secured to the front face of frame member 26 so as to cover the flattened portion 42 of the channeled member 4|, and also to the vertical support 23, usually is a vertical spacing member 52, similar to member 49 and coextensive with the latter, except that the member 52 is preferably not as wide as member A119 to accommodate the guide 4| which is positioned, usually, to the side of the upper sash member. A vertical frame member 53 is secured to the inner faces of support 23 and spacer 52, and member 53 is of the same general shape and length as frame member 50, except that the former is somewhat thicker than the latter, which provides space into which the sash 28 may swing, and has a portion cut out and rounded as at 55.

Co-operating with frame members 53 and 53 for both vertical and swinging movement with respect thereto, is a lower sash member, indicated as a whole by the numeral 56, having upper and lower rails 51 and 58, and

side rails

59 and 60, all of which enclose a pane of glass 5|. A channeled guide member 62, similar in all respects to guide member 31S, extends from the sill to the support and has a flattened portion 63, usually secured to the front face of frame member 55, being fastened to the latter by counter-sunk screws 54, or the like. A pair of spaced guide and hinge elements 55, similar in all respects to the elements 31, are secured to the side rail 59 adjacent the upper and lower ends of the latter. Hinge elements 65 have a flattened extension 68, as shown in Fig. 8, which is shown embedded in the side face of rail 59 that is adjacent to frame member 59, being fastened to said rail by countersunk screws 6l, or the like. ySide rail 59 also has a rounded portion 68 that co-operates with the rounded portion 5| of frame member 5i! to assist in providing a seal when the lower sash member 56 is in closed position, as indicated in Figs. 6 and 8. The arrangement is similar to the arrangement previously described for the upper sash 28, whereby hinge elements 65 fit within the channeled member 62, so that the lower sash 55 may be moved vertically at any time and also be pivotally moved about the longitudinal axis of the elements 65.

A channeled guide member B9, similar in all respects to guide member 4|, and best shown in Figs. 4 and 5, extends from the sill to the support and has a attened portion 'l0 that is usually embedded in the front face of the frame member 53, being fastened to the latter by counter-sunk screws ll, or the like. In its lower portion, guide member 69 is provided with elongated spaced openings '2 (see Figs. 1 and 10), similar in all respects to the openings lill and parallel therewith. A pair of spaced guide and locking elements '53, usually similar in all respects to locking elements 5, are secured to the side rail 59 adjacent the upper and lower ends of the latter, and have a flattened extension 'i4 that is embedded in the side face of rail 60 that is adjacent to frame member 53, being secured to rail 60 by counter-sunk screws l5, or the like. Rail 6@ has a rounded portion l5 that co-operates with the rounded portion 55 of frame member 53 to assist in providing a seal when the lower sash member 56 is in closed position. The arrangement is again similal1 to that described in connection with the upper sash member 2B, whereby the hinge elements 55 and the locking elements 'i3 act as guides within the channeled

members

52 and 69, respectively, during Vertical movement of the lower sash member 53, while the latter may be swung inwardly only when the locking elements 13 are in alignment with the openings 12.

A small spacer member v'l1 extends from the.

sill to the support 20, and is secured to the adjacent faces of support 2| and side frame member i in position to cover and conceal the iiattened' portion 63 of channeled member 62. A similar spacer 'I8 is secured to support 23 and side frame member I2` to cover and conceal the flattened portion l0 of channeled member 69.

It will be observed more particularly from Figs. 1 and 8 that the glass panes 33 and 5| are in proper alignment and parallel when the upper and lower sashes are in closed position. The meeting rails, 3! of the upper sash and 5l of the lower, as shown in Fig. 2, have their meeting faces inclined as at 'I9 and 80, and slightly overlapping as at 8|, to provide a weather-tightseal between the sashes. A conventional locking means 82 (Fig. 1) may be provided to lock th sashes in closed position.

A conventional sash balance is provided for each of the

sashes

28 and 55. The balancesv shown are indicated as a whole by the numeral 33, and are known as the Caldwell type of balance. These balances are available on the market and their operation is understood by those familiar with this art, so that a detailed description of its parts and operation is not believed to be necessary. As indicated in Fig. 3, each balance extends through an opening 84 in the support 29, and its base plate 85 is secured in the latter support by screws 85. Its cable 8l, usually metallic is spring controlled, and in the balance shown in Fig. 3, this cable passes through an opening 58 in the base plate 85 and usually has its lower end extending into and secured to the upper hinge element 35 of the lower sash 58, as indicated in Fig. 9. The cable 8l of the other balance may be similarly connected to the upper hinge element 3l of the upper sash member 28, as indicated in Figs. 1 and 2. It should be noted that the cables for their complete length extending from the balances are completely enclosed in the members 313 and 52 which are iixedly secured in the window frame so that the cables are never exposed.

As shown in Figs. 1 and 2, safety blocks 95 are secured to the lower surface of support 25 in vertical alignment with the upper rail 51 of the lower sash 55. This arrangement provides abutments against which the lower sash may strike in its upward vertical movement which will prevent the latching mechanism 82 from contacting support 2i! and being damaged thereby.

A rubber or rubber composition or other conventional sealing strip 9| (Fig. 2) is embedded in the upper end of rail 29 of the upper sash to' insure a weather-tight seal when the upper sash is locked in closed position. A weather-tight seal is obtained at the bottom of the lower sash member by beveling the lower front portion of bottom rail 58, as indicated at 92, so that the bevel 92 co-operates with the beveled portion |9 of sill i3, while a less beveled portion 93 on rail 5S co-operates with the beveled portion I8 on the sill. Thus, a tight fit is assured between the sill and the lower sash member.

l'n the operation of the sashes, their closed and locked position is indicated in Figs. 1 and 2, and after the latching mechanism S2 is released, either sash may be moved vertically up and down in the same manner that ordinary double hung sashes may be operated. During their vertical movement these sashes are guided by the oppositely disposed hinge and locking elements 7 moving within. the channeled members that extend for the full height of the window opening, and the sash balances will permit raising or lowering of the sashes to the desired extent.

In order to swing the lower sash inwardly like a easement window it is only necessary to align the locking elements 13 with the opening 12 (see Fig. 9) and the lower sash may be swung inwardly as indicated in Fig. 1.1. If the lower sash is down as in Fig. 1 when it is desired to swing it open, it is necessary to raise the sash a little in order to align elements 'I3 properly with the openings 12.

When it is desired to swing the upper sash inwardly, it is necessary to lower the upper sash until its locking elements 45 are in proper alignment with openings 44. If the lower sash has then been swung open, it is possible to swing the upper sash inwardly also, as indicated in Fig. 11. It will be observed that the upper sash cannot be swung inwardly until the lower sash has first been swung inwardly.

It will be realized that any size or number of the guide and hinge

elements

31 and 65 may be provided in the window construction of the invention. Likewise, the guide and locking

members

45 and 13 provided on the opposite side of the window sash of the invention can be of any desired size and number inasmuch as the

openings

44 and 12 are formed of complementary size and shape to the

slides numbers

45 and 13 whereby they may pass through such openings. Furthermore, the guide and locking rails 4I and 69 that are secured to the window frame may be of any desired cross section with the

slides

45 and 13 then being formed of a shape substantially complementary to the cross sectional contour of the rails with which such slides are engaged. It even would be possible in practice of the invention to use entirely diierent type of lock means on the releasable side of the window construction so as to retain it in a closed position at any desired time. Such means might even comprise a conventional device such as a spring bolt which would be carried by each of the window sashes and have keepers or receiving sockets provided therefor on the sides of the frame. However, normally I prefer to use some type of elongate guide means with which the free edges of the

sashes

28 and 56 may be releasably engaged for vertical sliding movement so as to retain such windows in tight association with the window frame at all normal times.

Since the cables 81 which extend down from the balances 83 are received within the

guide members

34 and 62, these cables are completely enclosed at all times. Such guide and hinge members are xedly secured to the window frame whereby it is relatively easy to clean around same and the movable cables do not provide any cleaning obstacle.

While in the drawings disclosed herein, the release points for both the upper and lower sashes are shown at the same vertical position, in some instances it may be desirable to provide such release points at spaced vertical portions of the window frame. Also, the pivot and hinge device could be horizontally positioned in place of vertically positioned.

The principles of the invention are applicable to any type of window construction and such window may be made from any desired material, either wood or metallic. Furthermore, the window construction is satisfactory for use with oriel windows, while it might also be used with a triple hung window where it is desired to have one or more windows movable and pivotal with relation to the others. Furthermore, in some instances the window construction might even be used with merely one window which has a vertical space into which it can be slid, when desired to expose the window opening. Also the construction could be used with a window which has only limited vertical movement in its associated frame. It should be noted that, as indicated in Fig. 11 of the drawing, both

sashes

28 and 56 can be swung through substantially 90: degrees movement in opening same to expose the window opening completely. This feature is achieved by the provision of appreciably wider side frames for the upper sash 28 with relation to the side frames that are used for the lower sash 56 and the differences in such width is compensated for in the assembly by the guide rails 24 and 26 in relation to the guide rails 50 and 53 forming part of the window frame. These members are complementary to the side rails of the window sash and their width diierences compensates for the differences in width of the window sash members.

In some instances it might be desirable to combine the space strips 49 and 52 with the associated frame strips 50 and 53, respectively, since itmay be preferable to form such members integral. Also, the spacer strips 11 and 18 might even be made integral with the rest of the frame members, when desired, only in such instancesv the arms 63 and 10 on the hinge locking members would then usually be made to extend along the outer surfaces of the window frame. Likewise the

entire side members

24, 49, 5D and 11 and corresponding members on the other side may possibly be combined to form an integral side member for the window frame. This construction would then have the guide and hinge members be secured to the exposed surface of the sides of the window frame.

It is believed to .be apparent that I have provided a novel window construction which has all the advantages of a double hung window and also has advantages over a easement window. The sashes may readily be reached for cleaning, painting, washing, etc., and can be positioned in any desired Avertical location for such action. Further, my window construction is well adapted for use with storm windows or screens and facilitates access to movement of same. In Figs. 2, 4, 6, 8 and 11, I have shown a storm window mounted in a storm sash 96 which is removably secured to a frame 91 that is permanently mounted in the outer sheeting I6 of the dwelling. As will be noted from Fig. 11, the storm sash may readily be removed and replaced from inside the dwelling after the

sashes

28 and 56 have been swung open.

Figs. 12, 13 and 14 of the drawings show a modification of the invention wherein special means are illustrated for retaining the slide members on the releasable edges of the window sashes in engagement with their retaining channels even when such window sash is positioned at its release point. This embodiment of the invention also illustrates a simpler type of vertical frame means which may be used in practice of the invention, but the apparatus disclosed, in general, is the same as that of the previous embodiment of the invention. Fig. 13 best shows that ller members IOI and |02 may be provided in the window frame and have vertical supports |03 and I04 secured thereto in any conventional manner. The front edges of the vertical supports ID3 and I04 may have conventional molding strips I65 and |06, respectively, associated therewith whereas any desired means (not shown) may be secured to the :filler members. Figs. 13 and 14 best show that a vertical frame member lill and |018 respectively, is secured to each of the vertical supports |03 and |04 and extends substantially the width or depth thereof and the forward surfaces of such vertical frame members lill and HI8 are provided with shoulders |09 and I il] and with curved surfaces |I Iv and |I2, respectively, similar to the other embodiment of the invention. A relatively smal-l vertical frame member IIS and II4 is secured to the transversely inner surfaces of each of the frame members lill' and |23, respectively, adjacent the outer portion thereof, that is, the portion adjacent the outside of the window frame of the invention. Any conventional means, such as elongate bolts H5 and l la and shorter bolts IIS and IIEa may be used to secure the vertical frame members IiVI and i818 to the remainder of the frame whereas the small vertical frame members II3 and lill may be secured in place in any desired manner. Bolts i5 also usually position a guide and hinge member IIl adjacent the rear of the window frame, and bolts IIS a guide and hinge member H3 adjacent the front oi the window frame, while bolts Iia position an anchoring and guide member or element IIS adjacent the rear of the other side of the frame while a similar anchoring and guide element |22 is positioned adjacent the front of the window frame by .bolts I ld.. A window sash, indicated generally by the numeral i2i, is provided for vertical sliding movement intermediate the guide and hinge member i i8 and the anchoring and guide member IZB and a hinge element |22 is secured to one lateral margin oi the window sash I2! for this purpose.

Fig. 14 of the drawings best shows an important feature of the invention which is that of providing a retainer lip |23 that is formed on the anchor and guide element at a release opening :'24 that is formed therein. This anchoring and guide member IZB engages with a guide element which is conventionally secured to a sill member i2E of the window sash i2 I. It should be noted that the retaining lip |23 adjacent the base thereof is outwardly and arcuately curved to be in snug engagement with the guide member |25 and that the lip |23 extends up approximately one third or" the diameter of the guide member 25 in engagement therewith whereas the outermost end of the lip 23 is curved backwardly upon itself, or outwardly with relation to the guide 25 to be completely free from same. Thus the lip |23 is adapted to retain the guide |25 in engagement with the anchor and guide member I2!) even when the guide is positioned at the opening |24 but that a slight force applied to the window sash I2! at the free edge thereof will spring the guide member |25 out of engagement with the lip I 23. Likewise, when engaging the guide with the lip |23, it can be temporarily iiattened, as indicated in dotted lines in Fig. 14 to engage the guide and lip. The lip |23 normally is integral with the anchor and guide I2II and is formed of such material, usually metal, as to be resilient and permit engagement of the lip and the guide member |25, or disengagement thereof, at any desired time but normally retain the two in a given relation. A similar lip |2'I is also provided on the anchor and guide member II9 at a release opening |28 formed therein.

In some instances, it may be desired to use another type of a retainer member, such as an overlying resilient clip, in association with the release lli) openings formed in the guide and anchoring members of the invention.

While usually not as desirable as the constructions illustrated herein, it is possible to form the hinge and guide elements carried on the window sashes, of such contour that they would engage with the outer surfaces of the hinge and anchor members rather than being received within the bores of such members, as shown.

Inner and outer in this specication and claims normally relates to the window and frame with relation to the house or other building with which the window and frame are associated.

While I have shown and described the preferred embodiment of my invention, it will be apparent that the invention is not limited thereto, and changes and modications may be made therein without departing from the spirit of the invention or from the scope of the subjoined claims.
