2 Claims.

The present invention relates to improvements in double hung sash windows for use in building structures such as dwellings, offices and factories.

The main object of this invention is to provide an improved combination vertically sliding and inwardly swinging sash structure, the upper and lower sash respectively consisting of a. rectangular vertically slidable frame and a glass-carrying-frame mounted for vertical swinging motion into the room in the slidable frame.

Another object of this invention is to out a rectangular recess or rabbet adjoining the inner edges of the. sliding frame and forming a fiange for concealing the swinging frame, the said flange being outwardly positioned and of such extent as to cover all the outwardly facing surfaces of the swinging frame so as to shield said swinging frame from exposure to rain or snow.

Another object of this invention is to provide seating and sealing means forming a storm-tight junction between the said. frames, so as to prevent the admission of rain or snow into the room when the inwardly swinging frame is in a closed position.

Another object of this invention is to provide a locking device which will automatically lock the inwardly swinging frame in a closed position or in any desired intermediate position between fully open and fully closed, and thus provide larger or smaller openings for ventilation to suit the convenience of the occupant of the house.

Another object of this invention resides in the particular arrangement and structural features of the cooperating elements.

With the above and other objects in View the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawing and pointed out in the claims which form part of this specification, it being understood that the embodiment herewith shown is merely illustrative and that various minor changes in the form, proportion, size and details of construction may be resorted to without departing from the spirit of the invention as expressed in the appended claims.

Reference will now be had to the drawing, wherein like numerals of reference designate corresponding parts throughout the several views, in which:

Figure 1 is an inside front elevation of a window equipped with vertically slidable double hung sash and improved with our glass-carryingframes for swinging motion into the room.

Figure 3 is a section of the easement and shows a top view of the lower sash with the glass-carrying-frame swung into the room, the section being: taken as on line 3-3 in Figure 1.

Figure 4 is an enlarged fragmentary portion of a modified combination rectangular slidable frame and glass-carrying-frame and shows the rabbeted edges of the rectangular slidable. frame and the outer sides of the glass-carrying-frame formed with a bevel all around.

Figure 5 isan enlarged fragmentary portion of a modified combination rectangular slidable frame and shows the rabbeted and beveled inner sides defining the aperture therein as. provided with sealing means forming a storm-tight junction.

Figure 6 is an enlarged fragmentary section of the glass-carrying-frame, the section being taken as on line 6-6 in Figure 3.

Figure 7 is an enlarged fragmentary section of the glass-carrying-frame, the section being taken as on line 7-'Z in Figure 3, and shows an intermediary locking device for locking the, glass-carrying-frame in any desired position between fully open and fully closed.

Figure 8 is an end view of a glass-carryingframe and shows a locking device which locks the glass-carrying-frame to the sash frame at the top and bottom when in a closed position, and which also serves for operating the intermediary locking device.

Figure 9 is an enlarged sectional view of a lockhead member forming part of the intermediary locking device.

In the illustrated embodiment of the invention, the several views show transparent glass window panes 10, 10, secured in glass- carryingframes 11, 11, mounted on hinges 12, 12, in the lower frame 13 and the upper frame 14 of a vertically slidable double hung sash window 15. The glass-carrying- frames 11, 11, are of rectangular form and are designed to enter into engagement with rectangular apertures 16, 16, in the upper and lower rectangular slidable frames for swinging motion into the room. The apertures 16, 16, are defined by rabbeted inner edges 17, 17, forming outwardly positioned rectangular flanges 18, 105 18, for concealing the swinging frames. The flanges 18, 18, projectfrom the edges 17, 17, a distance equal to the width of the woodwork of the glass-carrying-frame 11, and are designed to cover all the outwardly facing surfaces of the 110 swinging frame so as to shield said swinging frame from exposure to rain or snow.

As shown in Figure 4, the rabbeted edges 17-,- of the lower sash l3, and the outer sides 19, ofthe glass-carrying-frame 11, are formed with a bevel all around so as to form a seat and insure a tight junction between the swinging frame andthe rectangular slidable frame. A Weatherstrip 20, fastened to the lower rail 21-; ofthe glasscarrying-frame 11, has been provided for covering the lower flange 18, and serves as a drip to prevent rain or snow from getting into the room, It is to be noted that the beveled surface 19 has a downward direction into the room and that all the four beveled surfaces defining the rectangular aperture 16 taper towards the same point with the smallest end of the taper directed outward, out of the room.

As shown in Figure 5, the rabbeted and beveled side walls defining the aperture 16, have been provided with sealing means 22, forming a storm-tight junction. The sealing means 22, cornprises a dovetailed slot 23, a corrugated flat leaf spring 24, and a sealing member 25, having a cross-section of a segment of a circle. The sealing member 25, and the leaf spring 24, are iriserted into the dovetailed slot 23, at the time the sash is assembled and are designed to serve for the life of the window. The sealing member 25, is designed to recede into the dovetailed slot 23, when the glass-carrying-frame 11, is swung into closed position. It will thus be noted that the sealing member 25, extends all around the beveled sides defining the aperture 16, and seals the glass-carrying-frame 11, and cooperates with the beveled seat in forming a storm-tight junction and prevents the admission of rain or snow into the room when the inwardly swinging frame is in a closed position, and contacts with said sealing member 25.

As shown in Figure '7, the glass-carryingframe 11, has been recessed at its upper rail to provide a seat for a plate 26, having a through slot 2'7. The upper rail has also been provided with an elongated aperture 28, designed to house a lockhead member 29, having a reduced upper portion 30, which is adapted to enter into sliding engagement with the slot 2'7. The reduced upper portion 30, has been threaded to receive a screw 31, which serves to fasten a link arm 32, in pivotal engagement with the lockhead member 29. The said link arm being fastened in pivotal engagement at its other end with the upper rail of the sliding frame 13. The member 29, has been provided with an aperture 33, which serves to receive in sliding engagement a rotatable lock-bar 34. The lockhead member 29, has also been provided with a cross-slot 3'7, positioned in right-angular relation and in intersection with the aperture 33. The rotatable lockbar 34, has been provided with a plurality of spaced cross-slots 35, 35, and with a pinion gear 36, positioned at one end and flush with the end Wall 38, of the glass-carrying-frame 11.

As best shown in Figure 9, a spring 39, has been fastened to the lockhead member 29, and extends down into the cross-slot 3'7, and covers a portion of the aperture 33. It will thus be noted that when the rotatable lock-bar 34, is inserted in the aperture 33, with the cross-slots 35, 35, facing downwardly and the loclchead'member 29, is slid along said lock bar, that the spring 39, will enter one of the said cross-slots and will cause the link arm 32, to lock the glass-carrying-frame 11, in predetermined relation with the sliding frame.

As shown in Figure 8, there has been provided. upper and lower' vertically slidable lock-bolts 40,. 40, housed in the end wall 38, of the swinging frame 11, and being connected to an operating lever 41. by means of links 45, 45, and forced outwardly by springs 42, 42.- Each lock-bolt is beveled at the far end, where it is designed to enter an aperture 43, in the sliding frame 13. One of the lock-bolts 40, is provided with a rack portion 44, in engagement with the pinion gear 36, at the end of the rotatable lock-bar 34.

It will thus be noted that the operating lever 41, is pivotally connected to the links 45, 45, and to the lock- bolts 40, 40, and when pulled away from the swinging frame 11', the lock-bolts recede and become disengaged from the sliding frame and the rack portion 44, causes the rotatable lock-bar 34, to rotate and the cross-slots 35, 35, assume an upward position and unlock the swinging frame. The operator is then in a position, by further pulling on the operating lever 41, to swing the glass-carrying-frame 11, into the room any desired predetermined distance and on releasing the operating lever, the springs 42, 42, will cause the rack portion 44, to rotate the pinion gear 36, and to bring the cross-slots 35, 35, in a downward position when the spring 37, in the lockhead member 29, will engage with one of said crossslots and cause the link arm to automatically lock the glass-carrying-frame in an open position in fixed relation with the sliding frame, the said opening being dependent upon the predetermined spacing of the cross-slots 35, 35.

It is to be noted that when the beveled surfaces of the combined sliding and swinging frames are improved with the sealing means 22, that the corrugated leaf spring 24, is of ribbon-like thickness and is of substantially the same length as the sealing member 25, and forces the sealing member at a plurality of points all along its length into sealing contact with the beveled sides of the swinging frame.

Having thus described our invention, we claim as new and desire to secure by Letters Patent:

1. In a window, the combination with a vertically hinged glass-carrying frame mounted to swing in a rectangular aperture in a slidable frame, the sides of the aperture being rabbeted and forming a rectangular recess and an outwardly positioned rectangular flange in the slidable frame for shielding the outwardly facing sides of the swinging frame from external exposure, the four outer boundary sides of the rectangular recess being beveled and forming a tapering rectangular seat, the four outer boundary sides of the swinging frame being beveled and forming a tapering rectangular insert designed to permit seating contact in said tapering seat, said seat and said insert being positioned with the smallest end of the tapers directed outward, said beveled seating surfaces in said slidable frame being provided with longitudinal slots and spring-pressed sealing means recedable into said slots, said sealing means being positioned to contact only with intermediate portions of said tapering insert and adapting said seating and sealing mechanism to coact simultaneously and on all four sides of said swinging frame, and means for automatically locking said swinging frame in closed relation with said inclosing frame or for automatically locking said i ing frame in predetermined intermediate positions between fully open and fully closed.

2. In a window, the combination with a verti said seat and said insert being positioned with the smallest end of the tapers directed outward, said beveled seating surfaces in said inclosing frame being provided with longitudinal sealing means, said sealing means being in direct contact with intermediate portions of said tapering insert and adapting said seating and sealing mechanism to coact simultaneously and on all four sides of said swinging frame.
