COMBINATION TOP AND BOTTOM WlNDOW SASH AND FRAME.

SPECIFICATION forming part of Letters Patent No. 741,058, dated October 13, 1903.

' Application filed September 2, 1902. $erial No. 121,884. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH Moss, a subject of the King of Great Britain and Ireland, residing at Apollo Chambers, 326 Flinders Lane, Melbourne, in the county of Bourke, State of Victoria, Commonwealth of Australia, have invented certain new and useful Improvements in Combination Top and Bottom Window Sashes and Frames, of which the following is a specification.

The object of my invention is to provide a window the outside of which can be as easily cleaned from theinterior of the building as the inside of the said window. To this end I so construct the sliding sashes of windows that the lower half of each sash can be swung outwardly from the building and the upper half swung inwardly into the same. In the past the cleaning of the exterior of windows, especially those at an altitude, has been an exceedingly dangerous operation; but with my invention, each sash being pivotally supported near its middle on each side, the task can be easily performed without either danger or inconvenience. Various types of windows to meet these ends have been designed in the past; but with my combination, which is cheap and as readily applied to old as to new sashes, the number of parts are limited and the cost of the installation, therefore, trifling, in addition to which the top sash can be pulled to the bottom of the box-frame and be turned outside in as readily as the bottom one.

Referring to the drawings which form a part of this specification, Figure 1 represents an inside elevation of a top and bottom sash complete. Fig.2 is an enlarged interior view of part of the lower sash. Fig. 3 is a transverse section on line 3 3, Fig. 1, enlarged, looking downward. 7

Similar letters of reference indicate similar or corresponding parts where they occur in the several views.

On reference to the drawings it will be seen that the top sash A and the bottom sash B have on each side of them the stiles A and B, respectively. Each sashin its total width is narrower than the width between the parting-beads C, Fig. 3, secured inside the sashframe, so that the said sash is capable of passing through the sash-frame without meeting any obstruction.

Each sash is pivotally supported between the side slides E. The slides are of the same length as the stiles and are free to slide vertically between the beads C in the windowframe. Each slide may be connected near its top to one end of a sash-line F, which sashline passes over pulleys G and has attached to its other end sash-weights H, as in ordinary window construction. j

Above and below the pivot-pins D and on the meeting surfaces between each stile and its respective slide are dust and draft excluding strips J and J, strips J being on the stile and strips J on the slide. These strips are constructed to fit each other and may be integral with the slides and the stiles, respectively, or they may be added thereto. They are so arranged in relation to each other as to prevent rain, dust, or drafts entering the room. Preferably the windowframe is so constructed that the inner sash can be elevated sufficiently high for the top rail of the upper or outer sash (when it is down and the lower or inner sash up) to pull inwardly past the lower rail of the lower sash into the building. The upper sash can thus be pulled to the bottom of the frame and its outer surface pulled into the room and cleaned without mounting ladders or steps. 7

It will be seen by reference to Fig. 3 that the inner surface of each slide E is beveled or Wedge-shaped, as shown at E, and to the inner surface of the sash-stiles are attached horizontally-movable combination dust-excluding and locking slides or plates Q, provided with inwardly-flaring portions Q on their outer edges, adapted to engage the beveled faces E of the adjacent slidesE when the plates Q are moved outward. Each of these plates Q is made of metal, wood, or other material and has therein several horizontal oblong holes Q These plates Q, exclude all dust on account of the wedge-shaped contact of their outer edges Q with the surfaces E of the slides, and they are held to the stiles by suitable fastenings, button-headed screws Q being-shown passing through the oblong holes Q before referred to. The inner edge of each plate Q is preferably turned inward, as seen at B, Fig. 3, and formsa finger-hold by which the said plates can be moved to or from the slides. When the portion Q of the said plates are pushed over the slides, as seen in Fig. 3, they not only exclude the dust, but lock the sashes against swinging on their pivots.

When it is desired to clean the windows, the inner surfaces of the glass panes are cleansed while the sash and slides are locked by plates Q. Then plates Q are drawn inward and the sash turned on its pivots in the slides until the outer surface of the panes are brought to the inside of the building at an angle of about forty-five degrees.

With my invention each sash is capable of moving in a vertical plane and also moving on pivot-pins, and not only can the ventilation of a room be regulated; but the operation of window-cleaning is rendered practically quite safe.

Having thus described my invention, I claim- 1. In combination, the window-frame having sash-guides, vertically-movable slides in said guides having tapered wedge-shaped portions on their inner faces, a' sash hung upon and pivoted between said slides, and laterally-adjustable dust-excluding and locking plates attached to the inner faces of the stiles and provided with inwardly-flared portions adapted to engage the beveled faces of the adjacent slides, for the purpose and substantially as described.

2. In combination, the window-frame having vertical sash-guides, vertically-movable slides in said guides having dust-excluding strips on their opposed faces and having Wedge-shaped or beveled portions on their inner faces, a sash, pivotally hung on and between said slides, having dust excluding strips on its side stiles opposed to those on the strips, and laterally-adjustable dust-excluding and locking plates attached to the side stiles of the sash and having outwardly-flaring portions adapted to engage the beveled portions on the slides, all substantially as described.

In Witness whereof I have hereunto set my hand to this specification in the presence of two witnesses.

JOSEPH MOSS.
