WINDOW CONSTRUCTION.

Application 'flied rApril 25,

To all whomz't may concern.'

Be it known that I, THoMAsE. WALKER, a citizen of the United States 'of America, residing at Detroit, in the county of` Wayne and State of Michigan, have invented 'certain new and useful Improvementsin vJi/vindow Constructions, of which -thefollowing is aspecification, reference being had therein to the accompanying drawings. A,

This invention yrelates to windows havingv frames with sashes swingable therein, and more particularly to that type ofl window frame in which transversely hingedlysupported edges of sashesconstantly remain in the plane of the window frame with the hinge edges of the sashes adjustable in the frame so that thek sashes ymay be ,swung outwardlyA and lowered rkfor Ventilating and cleaning, purposes. Myy invention has further reference to the above type y'of window wherein superposed sashes have interlocking or interengaging meeting rails v'with said rails constructed so thatA theupper sash of the'window may be lockedin a closed position 'by' the ,lower sash, particularly when 'the'sashes aline or arel fully'withinthe window frame; As the windowfsashes are Ordinarily made -of metahadjustment of the upper sash, from an open toa closed position,

'may not at all times place the upper sash 1 in position to b e locked closedby the lower sash." In other words,`it'often` occurs that the upper sash is not fully closed'and conseunlocked .bythe closed flower sash, ory the upper sash must be further manipulated to sash locking it in a closed position.

Y The primary object of my invention is to furnish a window, as characterized above, with means for automatically and fully closing or placing an upper' sash withina `frame `,sothat itfmay be locked in a closed position by fthe lowersash, said means being actuated by ithe'lower sash 'to correctly, position the upper, sa'shso that portions thereof kmay bel engaged and held by the meeting railfo'f thelowersash. Y

vnl describing my 'invention byaid f as fragmentary views above referred to, l desire"l topoint out that some ofl the parts to fbe hereinafter. described arey duplicates, as

the vpresent'illustration simply shows one 1' side of awin'dow as having' a channel frame or stile 1 .with an upper sash 2 anda lower 'sash 3 y'adjustable lrelative to each other and also' relative to the frame. kIn the particu- Ilar ytype of window to which my invention refers, `thefupper sash 2 has its upper rail ,hingedly supported that the sash may be swungl outwardly andthe upper yhinged rail of f the," sash lowered lwithin, the window y frame. The upper sash'2` has ameetin'g rail which has a cross sectional shape Lproviding '"'aninner short legf andan outerlong lieg 6 and the short leg will be `again'speciif Gally referred te o The lower sash 3 is supported somewhat similar to the upper sash 2, that is, so that it may be swung outwardly relative to the window frame and the supporting rail of said sash raisedand lowered inthe window frame. The supporting rail of the lower sash 3 is known as the meeting` rail, and is designated 7. The cross sectional shape of this meeting rail provides, among other things, an inner long leg 8 which is adapted to overlie the short leg 5 of the upper sash 2 when said sashes are closed.

The meeting rail 7 of the lower sash 3 is provided with hinge members 9 preferably at the ends of said meeting rail, and said hinge members may Ibe connected tothe meeting rail by screws or other 'fastening means. The hinge members 9 are employed to hingedly connect the meeting rail 7 to a transverse member which is constantly within the easement frame and has its ends slidable in the rails or stiles 1. The transverse member, as best shown in Fig. 6, is preferably composed of an intermediate portion 10 and end portions 11, said end portions being standard for sashes and frames of various widths, and the intermediate portion may be made of various lengths so as to provide a transverse member of a desired length or width. This structural feature however, is optional with the maker of the window.

The end portions 11 of the transverse member are formed to receive the barrel portionsof the hinge members 9, and said hinge members are hingedly or pivotally connected to the end portions 11 by pintles 12 mounted endwise within the end portions 11, thus providing hinges fashioned after piano hinges.

Each end portion 11 has a vertically disposed shoe 13 extending above andbelow the transverse member and the shoe is adapted to slide in the frame or stile 1. `As best shown in Figs. 3 and 4, the frame or stile 1 may be provided with la channel wear member or liner 14 and the outer face of the shoe 13 may be provided with an adjustable or lixed wear plate or contact piece 15. That portion of the shoe 13 whichextends above the transverse member is provided with an outwardly projecting cam member or inclined way 16 having a comparatively sharp upper end` 17 adapted to impinge against theshort leg 5 of the upper meeting rail 4, at the end of said short leg, and `cause the partially closed upper sash to fully close so that the meeting rail 7 of the lower sash 3 may properly approach the meeting rail 4 and cause the short leg 5 thereof-to be sandwiched between the longL leg 8 of the meeting rail 7 and the transverse member which will be enclosed as the

meeting rails

4 and 7 are brought together. p y

With this type of window the upper sash 4 is first swung to a closed position or `approximately so, and then the lower sash 3 is closed causing the cam members to be elevated and impinge against the short leg 5 of the meeting rail 4, at the ends of said meeting rail. This takes place providing the upper sash 2 has not been completely closed, otherwise, the meeting rail 7 approaches the meeting rail 4 and the two rails assume positions about the transverse member. If the upper sash-2 is not completely closed the cam members 16 will deiiect or wedge the meeting rail 4 inwardly and as the upper sash assumes proper alinement with the channels 1, the long leg 8 and the transverse member of the lower sash 3 ride into position, as shown in Fig. 2 to retain the meeting rail 4 in aclosed position and against outward movement until the meeting rail 7 has been lowered. It is obvious that the bottom rail or edge of the lower sash 3 may be locked to secure bot-h sashes within the window frame. V

By reference to Fig. 3 it will be noted that the cam members 16 are enclosed by the frame and the channeled side rails of the upper sash 2 when said sash is closed, and since the transverse member is also rendered invisible by the closed sashes, the window frame and sash construction, in its entirety, will present afinished and neat appearance.

That I claim is 1. In a window, wherein upper and lower sashes are disconnected and independently tiltable and the lower sash holds the upper sash closed when said sashes are in alinement, the combination of a member adapted to support the lower sash, and means carried by said member adapted to contact with the upper sash to cause the upper sash to aline with the lower sash so as to be held closed thereby.

2. The combination covered by claim 1, wherein a portion of the upper sash is sandwiched between `said member and a portion of the lower sash. f

3. In a window frame, the combination of a movable lower sash adapted to have its upper edge move up and down in the window frame, an upper sash supported insaid window :trame and adapted to have its lower edge swung in an arc, and a cam member at the upper edge of said lower sash actuated by said sash to move .upwardly against the lower edgeof said upper sash and cause said upper sash to swing into vertical alinement with said lower sash.

4. The combination called for in claim 3, wherein there is a cam member at each side of the window frame with said cam members `disposed to be concealed when the sashes are closed.

.55. As a new article of manufacturefora window having sashes, a piece of hardware adapted to slide in the window to support one sash, said piece of hardware having cams at its ends adapted to impinge against the other sash and eii'ectadjustment of said sash.

6. In a window, a frame having independently adjustable swingable sashes with meeting rails adapted to be brought together so that one meeting rail may hold the other closed, cam members at the ends of one meeting rail to engage the ends of the other meeting rail and cause the last mentioned meeting rail to be deflected into the path of the first mentioned meeting rail to be engaged and held closed thereby.

7. In a window, a transverse sash supporting member having end portions slidable in said frame, said end portions being standard for frames of various widths, and

an intemiediate portion connecting the end portions of said member and having alength to properly space the end portions of said member to engage said frame.

8. In a window, an upper sash, a lower sash and a transverse member supporting said lower sash and having end portions shaped 'to slide in said frame and engage said upper sash, for the purpose herein specified.

9. A window as in claim 8, characterized by the lower sash being hingedly connected to the transverse member.

10. A window as in claim 8, characterized by said upper andlower sashes havingmeeting rails which enclose said transverse member when said sashes are closed.

11. As a new article of manufacture for a window having sashes, a piece of hardware adapted to slide, in the window to support one sash and by its sliding movement contact with and effect adjustment of the other sash.

In testimony whereof Ialix my signature in presence of two witnesses.
