8 Claims.

The present invention relates to improvements in the construction of windows of the type used principally for residences and ofiices, and is directed particularly to a reversible window construction which is useful for both indirect ventilating and convenient cleaning.

A principal object of this invention is to provide an improved window construction applicable to I either wood or metal fabrication in which a sash carrying frame is supported for bodily movement out of a fixed window frame forming a part of the building construction.

A more specific object of the invention is to be found in the provision for unobstructed movement of a conventional pair of vertically sliding sash in any position of the movable assembly.

A further and important object of the invention resides in the provision of a novel window construction in which the sash carrying frame can be moved to a position of spaced relation from the fixed window frame when indirect ventilation is desirable or necessary.

An additional principal object of the invention is to provide a window construction in which the sash may 'be quickly and easily reversed for safe cleaning or repair within the buildng. Specific features of improvement incidental to this object include provision for reversal of the window sash without removal of any of the parts of the window construction or disconnection of conventional sash balances.

Further specific objects of this invention reside in the provision for the conventional use of window screening and storm windows, adequate sealing of the movable window sash assembly in the fixed window frame, and preservation of an architecturally acceptable window appearance both from within and without.

A further specific object is to provide a window construction in which the sash may be reversed for convenience and safe cleaning without causing undue leakage of outside air into the building.

These and other features of improvement contributing to complete satisfaction in use and economy of manufacture will be apparent from the following detailed description of a preferred embodiment taken in connection with the accompanying drawings in which:

Fig. 1 is a partially sectioned inside elevation of the assembled window construction in normal relation;

Fig. 2 is a. vertical section taken on line II-II of Fig. 1 showing the assembled window construction to an enlarged scale;

Fig. 3 is a horizontal enlarged section taken on line III-III of Fig. 1 and showing the window components in a different operative relation;

Fig. 4 is a side elevation partly in section of the window construction in the operative relation of Fig. 3;

Fig. 5 is a cross-sectional view taken on line V-V of Fig. 2;

Fig. 6 shows an inside elevational view of the assembled window with certain parts removed for purposes of illustration;

Fig. 7 is a vertical section to reduced scale taken on line VIP-VII of Fig. 4 with certain parts in a diiferent adjusted position;

Fig. 8 is a partial cross-sectional view to an enlarged scale taken on line VIIIVI[I of Fig. 1: and

Fig. 9 is a fragmentary inside elevational view partially sectioned showing a bottom portion of the movable window frame assembly.

As seen best in Figs. 3 and 4, the window construction of this invention comprises a window wall frame It] to be fixed in a corresponding opening in a house of other building, and a bodily movable and reversible window sash assembly l2 connected with the wall frame 10 by upper and lower linkages I l and I6. The relation of the frame It] to the opening in the house or other building is shown by dotted Wall lines WL.

The fixed window frame I0 comprises an upper horizontal member or lintel I8 and a lower horizontal member or sill 20 secured at their ends to a pair of vertical uprights or framing

members

22 and 24. A rectangular outer facing frame 26 covers the outer edges of wall frame It) and overlaps the adjacent margins of the building structure in which it is mounted. Adjacent its lower portion and immediately above the sill 20, the facing frame 26 is provided with a drain ledge 28 extending the full width as shown in Fig. 3. The drain ledge or strip 28 is formed with a convex inner edge 29, extending throughout the widthwise opening provided by said frame, for sealing purposes which will be more fully described. An inner mold strip 30 of rectangular cross section extends interiorly around the other three side edges of the facing frame 26 in the manner shown in Figs. 2, 4 and 7 to serve as a guide and seal for the movable sash assembly I2.

With reference to Figs. 2, 3 and 4, it will be observed that the window sash assembly l2 which is mounted for bodily movement includes upper and lower

framed sashes

32 and 34 guided for vertical movement by

parallel side jambs

36, 36 having respective side facing members 31 secured thereto and extending laterally to cover the inner edges of the

members

22 and 24 of the fixed wall frame ill. The jambs 36 are connected at their upper ends to an overhead lintel 38 and at their lower ends to a sill member 39 of special shape. The sill member 39 is formed to provide a central inwardly inclined portion 40 terminating in a concave edge 4! formed and arranged for complemental engagement with the convex inner edge 29 of the drain ledge 28 as shown best in Fig. 2. The size and slope of the inclined or wedge portion 40 is such as to fi1l snugly the wedge-shaped opening of the facing frame 26 adjacent the sill edge 29. Theremainingcinner portions of the sill 39 adjacent-the respective ends of the wedge portion 49 will engage and abut the corresponding portions orthe insideof the outer frame 28 as indicated in Figs. 3 and 7.

Figs. 2 and 8 best show the manner in-which 1 the overhead lintel 38 and the side jambs 36 engage the adjacent side of the inner; mold strip 39. whenthe window sash assembly. is received. in=.the frame). The sash.32.;and 34are of conventional construction andarrangement for slid-- ing between a vertical parting strip 42 and inner.

and. outer-stopstrips 44.2;aand .46. disposedas shown in Fig. 8. A conventional ledge member 4111s secured to the inner marginal portion of the sill w39 soas to ,provide:further guiding and. abutment for the lower.sash-;34;The side facing members 31, 3l.extend..betweenand .abut the inward projections. of. overhead. lintel 38. and the sill member 39.

Figs. 1 and-4 illustratev-theimanner in which conventionalformsof sashloalance maybe associated with the

sash

32 and 34. In the preferred. embodiment. these. sash. balances. comprise weights 48; 48 arrangedon oppositesides of each sash and connected:witlrrespective cords 59 xtending over. pulleys 52;;52 tocengagelrespectively with the balanced sashes; .321: and 34;

Thedetails, of. the uppenandlower sash link-- ages. 14 and; i6. will ..be:.understood .from a con siderationof Fig. .3. The linkage. has a pivot pin connection 54 .witlra hingeplate:56= located at its ,inner. end and. securedito the=upper: horizontal framing member 8 :by.; means-such as a plurality of screw threadedif asteners fl 58,-. The framing member [8. is prov-idedtwith' a recess 60 at -its inner right end,.formed andarranged to-so receive, the, linkage. .l 4 in its collapsed or folded position. At titsouter endthe linkage I4 has-.a similar pivot. pin. connection Elwith a hinge plate- 64'lsecured -.-by., screwithreadedtfasteners 66,- B6- toithe central portionof the. inner :face of a pivot- 5o ally mounted. upper. trim B8;..'I'he. uppertrim 68 is mounted for pivotingonthetsashrframelintel 38 and a corresponding pivotally mountedlower trim IO-is carried on the undersidepfthe sashframe sil139, the pivotal axes being central,,and aligned. c

vertically.

Further. details of ,the pivotal; association of thetrimmembers-SB and ldwiththe sash frame are shown in Fig. 9 which illustrates the mount ing of trimlil, .it being understood ,that them-135 verted mounting of the upper. trim 691s the same. A headed pivotppin 'H is threadedly secured in the trim l0 and extendsjloosely through a securing and bearing plate 14" which is inset in the underface of the sill 39 "and secured in place by 70* countersunk screws 16516: The sill member 39 is also recessed atldto-provide clearance for rotation-of the-headedpin 'IZ-With-the lower-trim- 10. Pivot pin 12 issecured-againstrotation in' trim 10. and turns loosely inthe bearing plate"-'l4'.-

As the construction and arrangement of the linkage i6 is similar except for its location on the bottom and at the opposite side of the sash assembly 12, it will suffice to note that an inner pivot pin connection joins the linkage to a hinge plate 56, an outer pivot pin connection 82 is associated with hinge plate 54, and the upper inner. edge portion of the framing sill 29 is recessed at 84 (Fig. 4)-to receive the linkage. Each separate linkage means, M or (6, is of a length sufficient for reversing of the sash assembly 12 in its inner pivoting position.

The upper linkage 44 comprises a long link 86 pivotally connected to a short link 88 disposed adjacent the-trim 68.-- A leaf spring 90 is secured to one side of the long link 86 and formed and arranged to extend over the connection between the two links and an adjacent edge of the short link- 88--to provide a yielding stop against straightening of the toggle connection of the linkage and folding of the linkage-in the opposite direction from thatishown inFigs. 3 and,5. The manner in which the spring 90:;cooperates with the links. 86;.and .Sdwhen the bodily movable window sash assemblyis ,completelywithdrawn fromthe fixed frame It is clearly shown in- Fig. ,3.

Figs. 2 and 5 show..thepreferred manner of holding or looking the movable-sash assembly l2, withinthe fixed frame; lilfor. use in a convene .tionalmanner. For this purpose, individual bolts 92'.are. arranged to extendoutwardly through the overhead lintel 38 and the..sill 39;,respectively, forv threaded .engagement.;with, nut vvmembers 94 countersunk and. retained in. the upper framing v, member 18; and the lowerframingmember 20 of the fixed vframe 10.1: Each bolt, 92; is provided with a butterfiyheadilfia which is countersunk in the innerface of the overheadlintel-38or the sill39 asthe case maybe when the threaded ends of-the bolts :are tightened intothe nuts 94. The head .95 of the lower bolt. 9.231s covered bythe bot-. tom of the sash at when thelatter is in a closed position,. andthe head 96:.ofthe corresponding upper. bolt 927.comes between the parting. and stop strips whereit will. be.-.inconspiouous.a It will be, appreciatedthat these boitsare readily accessible, fromatherinside .ofithe window- .and that, they, cannot. be tampered .with, or released when the upperiandllowe-r sash...are closed .andlocked in. the usualimanner. Fig-=5 shows the manner in which the bolts 92 are arranged to pass through the sash linkages. when .thellatter. are. in closed position.

In. order .to secure and steadyithe -bodily movable window sash assembly. 12in its spaced posi-. tionavithini the house. OIqOthEI'a-blllldil'lg .(Fig. 4)., detachablestrutmeans-in theform of metal gatet hooks 98, 98 may be pivotally connected [to the. inner. sides .of the verticaltframing members 22 and 2t adjacent the bottomvand engaged witheyes 99;99securedto. the inside faces of the verticalfacing members- 3i of-the movable sash frame. The-fixed

framing members

22 and 24 also oarryretaining pins lilil for holding the gatehooks-98- in vertical position when not in: use, as. illustrated-in Fig. 7.

The'usefulness andversatility of the windowconstruction of this invention-will-appear-more fully'irom thefollowingdescription of its operation and use.--- When-the movable Window sash assembly {2 is secured within the fixed frame ID as shown in Fig. -2, theindividual sashes 32- and 34-m'ay be slid-up and down; i-n-the usual manner. 1 The movable assembly l2=is unsecured by-loosen-- ing andwithdrawing-theupper bolt '92-*by means of the inwardly exposed head 96, and the lower bolt 92 may be removed in the same manner after the lower sash 34 has been raised sufficiently to provide access to the bolt head 96. This unsecurin is quickly and readily accomplished from the inside of the building with which the window is associated. A straight inward pull on the window sash assembly l2 will move it bodily out of the fixed frame It and unfold the upper and lower linkages l4 and [6 which suspend it from the fixed frame Hi. This position of operation is shown in Fig. 3 after the hooks 98 have been connected with the eyes 99 on the inside of the facing members 31 of the movable sash frame. In this position indirect ventilation of the interior of the building is provided around the whole inside periphery of the fixed frame It. It will be particularly observed that no part of the window construction required adjusting or moving in this operation, except for separation of the securing bolts 92. The sash weights 48 and cords 50 are now exposed for convenient adjustment and repair, although conveniently removable boxing in sides can be provided if desired.

When the hooks 98 are unfastened the vertically aligned central, pivotal connections provided by

pins

12, 12 permit the window sash assembly I 2 to be rotated through a half turn or 180 degrees from the position shown in Fig. 3. This turning places the side facing members 31 adjacent the inner edges of the upright framing members '22 and 24 against which they may be pushed in order to close the opening of frame Ill while the insides of the

sash

32 and 34 are being washed, repaired or painted. The pivotally mounted upper and lower trims 63 and Hi to which the pivot pins l2, l2 and the linkages l4 and it are connected will remain facing in the same direction in order to accommodate this half turning of the remainder of the window sash assembly and inward movement with the linkages to seal the upper and lower edges of the opening defined on the inner side of the fixed frame H).

In addition to the complete sealing provided by the inner mold strip 30 and interfitting of the wedge-shaped sill portion 40 with the drain ledge 28 of frame l9, weatherstrips may be added around the outside edge of side jamb 36 and the window asembly lintel 38.

It will thus be seen that the objects of this invention have been attained by providing an attractive window construction having a window sash assembly which may be moved inwardly for purposes of indirect ventilation and reversed for convenient and safe access to the outer sides of the window sash without appreciable leakage of air into the room during the operation. These objects have been accomplished without materially increasin the cost of the window construction or material departure from conventional features, and without requiring the separation of any of the window parts during operation.

While a preferred embodiment of this invention has been described in detail, it will be appreciated by those skilled in the art that various changes can be made in details of construction and arrangement of parts without departing from the principles of the invention and the scope of the appended claims.
