HUGH GORD ON MACWILLIAM, OF NEW ROCHELLE, NEW YORK.

' wmnow.

Application filed May 18,

To all whom it may concern Be it known that I. Huon G. MAowiL- LIAM. a subject of the King of Great Britain, and'resident of New Rochelle. in the county of lvcstchcster and State of New York, have invented certain new and useful Improvements in' Windows, of which the following is a specification.

My invention relates to windows and has particular reference to a type which combines the advantages of a sliding sash for general purposes and a swinging member on each sash acting as a frame for the glass and by the use of whichswinging feature the glass may be easily and readily'cleaned both on the inside and the outside faces.

One of the objects of my invention is to provide window sashes of the type described which are practical and of low cost and which can be easily placed in any ordinary window frame and in such a manner that repairs may be easily made and outside screens, storm sashes. or blinds of full or half length may be permanently attached without interfering with the operation of the window. I

A. further object is to produc-ean eilic ient combination of sashes which may each have a maximum of light giving space.

Another object is to provide means for making all joints around the swinging mem bers water and air tight as nearly as may be required.

Further objects are to provide proper joints between the sliding sashes when closed, to eliminate any rough projection on either surface of the sashes. and to providelocking means forsaid swinging members, locking means for said sliding sashes when closed, and aligning means for said sliding sashes when in registering position whereby the upper swinging member may be swung through the lower sash when the lower swinging member is open, and without danger of window breakage.

. Another. object is to provide supporting hinged means whereby the lower swinging member may swing clear of the upper swinging member when the latter is Other objects will become apparent as the description proceeds.

My invention consists in such novel features of construction and arran ement of parts as are hereinafter described and particularly pointed out in the claims .hereto appended, one practical embodiment of my "the usual manner the two sashes may opened.

invention being shown in the accompanying drawing in which- Fig. 1 shows the general appearance of a window having my improved features.

Fig. 2 shows a part vertical side section through the window sashes. with the sashes and swinging members closed and locked.

Fig. 3 shows a similar part section with both sashes aligned in registering position.

Fig. 4 is a detail view in section on line 4% of Fig. 3 showing wide opening of the upper swinging member. I

Fig. 5 is a detail of the sash construction.

Fig. 6 a detail of the flush member locking means. i

Fig. 7 is a top view of the sashes showing the beveled feature of the side edges of the swinging members.

Similar reference characters refer to similar parts throughout the several views.

I intend no limitations other than those of the claims A window frame lof ordinary type is illustrated having fitted thereto my improved sashes. top 2 and bottom 3 both of which slide in a well known manuerfithe weight cords of-thc sashes being shown for example as at 4 passing over pulleys 5, only oneofwhich is shown. These sashes 2, 3, may have each an outside. sliding. and an inner swinging spectirely; the swinging member 9 of the upper sash being smaller than the smallest part of the opening provided in the lower sash for closure by swinging member 10.

' Locking means are provided as for example a lock 6 on the lower sash frame 3 and a catch 7 on the lower rail of swinging member 9. A similar catch. 7 may be swinging rigid frame member 9, 10, re-

placed on the upper portion of the sash-2 arranged to take into a \rcccss R in the window casing 1 when the By sliding sash 2 down andsash 3 up brought into registering )osition (Figfli) in which position the catch 7 of the upper sash may coact with the lock 6 of the lower sash to hold the two window sashes fixedly together. The swinging members 9, .10, may then be-swung inwardly one after the other as for cleaning or mending purposes. The swinging members are locked. in closed position as by flush locks 11 (Fig. 1 and Fig. 6). These locks may be: opened by the insertion of a key and may be of an standard type but if used should be'fiusii upper sash is closed.

frame flush with the beveled edge 13 against 10 which the beveled edge 14 of the swinging frame abuts, the other art of the hinge be ing flush therein. Sas es 2 and 3 are provided with Weatherstrip frames 15, 15 re- -s actively, having each a periphery of the 15 s ape and bevel of the sides of the respective swinging member opening and having an angle cross section as shown. The frames 15, 15 are disposed between the members 3 and 10 and 2 and 9.respectively when the .29 swingingtmembers are in normal position, 1 and eac frame ---provides a lip portion against which the respective .swingin r member tightly closes. One flange each Weatherstrip frame is sunk into the beveled 2 ed as 13 of the rails of its sash (Fig. 4),

an a channel or more is out in the face of each of the swinging members 9, 10. as shown at 16, 16 (Fig. l) which inter-fits with the upturned lip portion of the 39 weather strip 15, when the swinging 1 members are closed.

* The upper swinging member 9 is supported by a hinge 19 (Fig. 4) sunk in both the sash and the member edges and the memher 9 ma be opened, at least 90 degrees through t e lower sash opening when the member 10 is swung fully open.

In closed position of the sashes the swinging member'- 9 cannot be opened because it I 69 abuts the lower sliding sash 3 and in fact the member 9 can only be opened with both sashes registering.

With both sashes closed the lower sash cross bar interlocks at the center joint 21 with the upper sash cross bar (Fig. 2). in order to provide for this joint and yet permit sliding the sashes together the lower sash top cross bar is wider than the bottom cross bar while the upper sash top cross bar is narrower than its bottom cross bar as shown.

Having thus described one embodiment of my invention what I desire to claim is 1. In a window, an upper sliding sash frame having a centrally disposed SWlIl ing member and a lower sliding sash frame aving a centrally disposed swinging member. means to lock both sashes together in registering position at any point and means whereby said upper sash swinging member may be swung inwardly through a centrally disposed opening in said lower sash frame, when the swinging member of said lower sash frame is open.

2. In a window, an upper slidin sash frame having a centrally d'l posed swinging n gmber and a lower sliding sash frame, having a centrally d sposed swinging member, means to lock said frames together in closed position, additional means adapted to coact with part of the first mentioned means to lock said frames together in registering position, and locking means for said swinging members, substantially as described.

Signed at New Rochelle, in the county of Westchestr and State of New York, this 18th day of March A. D. 1920.
