WINDOW.

Specification of Letters Patent.

Patented May i e, 1919.

Application filed November 6,191?. -Serial No. 200,611.

'1 'u cell who nt it may concem Be it known that I, ALEXANDER E. KUNE- MAN, a citizen of the United States, residing at Erie in the County of Erie and State of Pennsylvania, have invented new and useful lu'provements in Windows, of which the following is a specification.

The object of the invention is to form a window with a sliding sash or sliding sashes which may be readily swung inwardly so as to permit of the cleaning of the outer surfaces of the windows.

The invention is illustrated in the acoompanying drawings as followsz Figure 1 shows a front elevation of a Window, the lower sash being open.

Fig. 2 is a similar View, both sashes being slightly swung.

Fig. 3 a front elevation, partly in section.

Fig. 4: a section on the line i-t in Fig. 3.

Fig. 5 a section on the line 5-5 in Fig. 3.

l marks the casing, 2 the inner stops, one of which is removable, 3 the intermediate stop at one side of the window, 3 the outer stop at the same side, 4- the outer stop at the opposite side of the casing, 5 the lower sash and 6 the upper sash.

Arranged at one side of the casing (the side having the stops 2 and 3) are the hinges 7. As shown they are secured to the casing. These hinges are provided With the thuinb screws 8 by means of which the lower sash may be detachably secured to the hinges With the sash slightly raised so as to be free froni any stop at the bottom. The

hinges are preferably formed with an ofset 9 so that clearance is made for the thumb screws 8. The weights may be detached, or if the chains 10 and 11 have suiiicient length the sashes will readily swing free exposing the 'outer surface. The inner stop opposite the hinges is detachable so as to permit the inward swinging of the windows.

An intermediate stop 12 is arranged opposite the intermediate stop This interinediate stop is arranged preferably at the top of the sash 6 and terminates above the lowest position of the edge of the upper sash so that the upper sash when moved downwardly will clear this stop12 in swinging inwardly. A stop 13 is secured to the front or inner face of the upper sash 6 and is preferably forned in continuation of the stop 12 when the window 6 is closed. The casing is preferably provided with a step 14:, This forms a stop for' the lower sash;

perfect sliding face provided for the lower i sash' so that aproper fit may be made by adjusting the stop 2 opposite the step 14.

The lower sash may be swung inwardly for cleaning by raising it securing the hinges, removing the opposite stop 2 and swinging the window inwardly. This operation is clearly shown in Fig. 1. If it is desired to swing the upper sash inwardly, it is lowered bringing 'the hooks 15 which are arranged on the upper rail of the sash into openings 16 in the top of the lower sash. The upper sash is thus hung on the lower sash. As the lower sash is swung inwardly it is carried with it, thus bringing the outer surface of the upper window to within the building so that it may be readily cleaned.

It will be noted thatthe stop 13 acting against the outer face of the lower sash holds the upper sash in place as it is lowered. When the upper sash is attached to the lower sash by the hooks 15 and the sashes swung out the stop holds the lower portion of the upper sash spaced from the lower sash so that the sashes will close in proper relation and consequently the upper sash will clear stop 3 as the sashes are closed.

It will also be noted that when the sashes are Secured together they swing as one piece, and this piece is more than double the thickness of 'one sash. The step 14: is particularly advantageous in this connection, because it allows the outer sash to clear the casing as the windows are shut with a close fit between the outer sash and its guideway.

What I claim as new is 1. In a window, the combination of two closure members comprising a casing and a lower sash swingingly mounted in the cas ing; an upper sash slidably mounted in the casing; means for securing the upper sash to the lower sash whereby the upper sash may swing with the lower sash; and a stop carried by one of the sashes and engaging the opposing face of the other sash holding the upper sash in spaced relation to the lower sash as the upper sash is raised and lowered and as the sashes are swung together.

2. In a window, the combination of a eat-sing having; sash slides at one' side and its opposite side provided with stepped ways, the inner Way being stepped outwardly from the Way for the upper sash; an upper sash slidingly mounted in the oasng; a lower sash slidingly nounted in the casing and sliding against the step in the casing; means for securing the lower sash to a swinging mounting; and means for securing the upper sash to the lower sash Whereby it may be swung inwardly With the lower sash.

3. In a Window, the conbinaton of a easing having sash slides at one side and its opposite side provided With stepped ways, the inner way being stepped outwardly from the Way for the upper sash; an upper sash slidingly mounted in the casing; a lower sash slidingly nounted in the cusng and sliding against the step in the casing; neans for securng the lower sash to u swingng mounting; means for securng the upper sash to the lower sash Whereby it may be sWung inwerdly With the lowe` sash; and a stop ca''ed by one of the sushes and engaging the opposng face of the other sash holding the uppesash in spaeed relation to the lower sash :s the upper sash is raised and lowered and as the sashes are swung together.

In testinony Whereof I have hereunto set my hand.
