SLIDABLE WINDOW-SASH SUPPORT.

Application filed September 7, 1926.

My invention relates to windows and has particular reference to a slidable mounting for the upper sash of the window which allows the pivoting of the said sash at its lower end, so that it may be swung into reversed position to present the outside of the sash inwardly for cleaning or for ventilation.

The object of the invention is to provide a mounting for the upper sash of a window which will allow said window to be raised and lowered in a vertical direction, but which will also allow the swinging of the upper end of the sash inwardly. It is desired to so connect the upper sash with a movable rider or stile that the sash may be swung inwardly with a minimum of ma nipulation. It is also desired to form the connection in such a manner that the construction will be economical to manufacture and simple in its operation.

Referring to the drawing herewith, Fig. 1 is a side elevation of a window casing, the upper portion of the window jamb being in vertical section approximately on the line 1-1 of Fig. 3. Fig. 2 is a side elevation of the window sash removed from the frame of the casing, the upper sash being in reversed position. Fig. 3 is a broken trans verse section approximately on the line 3-3 of Fig. 1. Fig. d is a broken front elevation of the upper sash showing the rider attached thereto. Fig. 5 is a top plan view of a sheet metal rider which may be used. Like numerals refer to like parts in all the views.

In the drawing 1 have shown a window casing 1 having a vertical channel 2 for the lower sash and a similar channel 3 for the upper sash. The improvement constituting the invention resides in the mounting of the up er sash and attention is, therefore, called to igs. 2, 3 and d. The upper sash 4 is mounted for attachment to riders 5, one on each side of the sash. These riders may be made of wood, as shown in Figs. 2, 3, and l, and in such case the sash cord may be secured to the rider adjacent the upper end. The rider is provided with a groove 7, which, as indicated in dotted lines in Fig. d, extends only part way through the rider from the inner side. A laterally projecting pin 8 at the lower end of the sash is adapted to fit within the groove 7 and to be adjustable therein. To secure the sash to Serial No. 133,923.

the rider a plate 9 is mounted upon the upper end of the rider, said plate having a flange 10 bent inwardly above the sash and adapted to fit closely against the upper face thereof. On the side of the rider presented outwardly a groove 11 is formed along the inner edge to provide a rain pocket, the position of which will be indicated in Fig. 8. This pocket is intended to catch water or moisture entering around the outer side of the sash and to allow it to drain downwardly and thus guard against its entrance past the window into the room.

lVhen the sash is in upright position upon the rider as shown in Fig. 4., the sash may be raised and lowered, balanced by the sash weights in the usual manner. WVhen it is desired to throw the upper end of the sash inwardly to provide a vent at the upper end or to reverse the sash, it is released from the plate 10 at the upper end and swung inwardly, and as the upper end is moved into the room the pivotal pin 8 may be moved upwardly in the groove 7 in the rider. It will be noted by reference to each of Figs. 1 and 2 that the upper side of the lower sash has been beveled orrounded upon its outer face where it is adapted to contact with the upper sash. This beveled portion has been arranged to act as a fulcrum about which the upper sash may turn or rather oscillate when it is being reversed. As the reversing movement is started the upper sash first bears up this beveled or rounded surface of the lower sash and the pins 8 are forced upwardly in the grooves 7. Thus a device is provided which tends to ease the shock in event the upper sash falls inwardly as it must fulcrum around the beveled portion, as well as the top face of the lower sash. This will allow the sash to be swung downwardly until it contacts with the up per end of the lower sash 18, as shown in Fig. 2. This will give access to the outer side of the window pane for cleaning.

If desired the rider may be made of sheet metal construction throughout, and in such case the sheet metal will be bent into a tubular form, such as is shown in Fig. 5, leaving an opening 14 in the sheet metal body 15, which provides for the rain pocket shown in the wooden construction.

The advantage of this mounting for the upper sash lies in the fact that the sash may be not only vertically slidable as is usual with window: sashes, but the sashvislalso allowed to be reversedto give access" to-the outside of the window sash for purposesof cleaning when desired, and thus reversal of the sash niaybe performed with little difficulty and without material change in the usual mounting of the sash. f I v Ilaving thus described my invention, what I claim as new and desire 'to protect byLetters Patent is:

3'1. A wi-ndow including a lower sash, an

' upper sash having its lower end overlapping the outer side'of said lower sash, riders for said upper sash,'said riders having grooves therein from a point adjacent-their lower ends toabout midway of said riders, pins at the lower end of said sash fitting slidably in said riders whereby the upper end of said upper sash may swing inwardly to lieagainst said lower sash, for the purpose described.

2. A window including a lower sash,an upper sash having its lower end overlapping the outer side of said lowersash, riders for said upper sash, said ridershaving grooves therein from a. point adjacent their lower ends to about midway of said riders,;pins at the lower end of said sash fitting sl-idably in said riders whereby the upper end of 4. In a window construction, ran upper partially reversible sash, riders for said upper sashjand pins slidably connecting said IlClGTS and upper sash, a lower sash having the upper side 1 thereof beveled to form :a

fulcrum upon which said upper sash'inay oscillate.

Intestinieny whereof 'I" hereunto affix my signature this day of August, AfD. 192 6.
