Application led September 8, 1916. Serial No. 119,072.

To all whom 'it may concer/n.'

Be it known that l, WILLIAM S. Burnin, a citizen of the United States, residing at Chicago, in the county of Cool; and State of lllinois, have invented new and useful lmprovements in TWindow-Sashes, ofwhich the following is a specification.

This invention relates to windows and particularly to the sashes for windows which, through the use of this invention, may be easily removed from the window frames.

The object of the present invention is to provide a window frame with a simple, inexpensive, and reliable means for releasing both the upper and lower sashes from the grooves in the sides of the window frame, and from the sash cords without having to withdraw nails or screws when repairs, cleaning or painting is required.

Another object of the invention is directed to the attachment of the sash cords to the sash, by means of hook-like terminals on the outer ends of the cords that engage with the under side of the sashes and are held in engagement therewith when the sashes are in operative position, means being provided to catch the hooked ends of the terminals and hold the sash cords when the sashes are removed.

Other details of construction will be set forth in the following specification and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of a window complete provided with the improvement, a portion of the window frame being broken away;

Y Fig. 2 is a vertical longitudinal sectional view of the window frame, the edges of the sashes being shown in elevation, and

Fig. 3 is a detail perspective view of one corner of a window sash showing the sash cord holding means.

In the drawing, 10 indicates the window frame as a whole, 11 the jambs and 12 the window sill. As usual, the jambe 11 are each provided on its inner face with two parallel grooves 13, 111, formed by an inner molding strip 15, an outer strip 16 and a parting bead 17. Usually these three strips are continuous from the top of the window to the sill 12, but for the purpose of the present invention, the molding strip 15 and parting bead 17 are each formed of two longitudinal sections, divided a few inches above the meeting rails of the lower sash 18 and the upper sash 19 when the window is closed and connected as shown by a lap joint 2 The upper sections 21 of each molding strip 15 and parting bead 17 are fastened in the usual manner to the window frame by the use of nails. rfhe lower section 22 of each molding strip is held in a straight line with the upper section by means of a swinging latch or tongue 23, pivoted on the upper section 21 and adapted to swing over and retain the lapped end 20 of the lower section 22. Projections of any kind may be pro vided on the lower section22 to enter freely into recesses in the j amb 11 and sill 12 to prevent the section slipping. Instead of the swinging latch 23, any other desirable form of fastening may be employed.

The lower section 2l of the parting bead 17 is sustained in the same manner as sec- Jtion 22 and maintained in place by a latch 1n the sides of each sash are formed grooves 26 that extend longitudinally from top to bottom of the sash. rlfhese grooves form seats for metal strips 2i" that lie flush with the sides of the sash and permit the sash to slide freely7 in the window frame 10. Each metal strip 27 is preferably made nearly as long as the groove 2G and has an eye 28 in its upper end to which one end of the sash cord 29 is fastened. The lower' end of each strip is bent at a right angle toward the sash to form a foot or hook-like projection 30 that enters re ess 31 in the bottom of the sash. A cross notch 32 is made in the bottom rail of the lower sash 18 at each side which intersects the recess 31 of the same side, each notch being of such size that a swinging or other form of catch 3?), seated in a depression 34- in the window sill 12, can enter said notch and pass above the foot 30 of the metal strip 27. Similar cross notches, shown in dotted lines l? ig. 2, are made in the under side of the parting rail of the upper sash 19.

lli/'ith a window equipped with the means described, the sash may be easily removed and replaced without much effort. rl`he lower sash, if raised, is drawn down into closed position and the catches 33 on the window sill engaged with the hoolelile projections or feet 30 on the metal strips 27. rllhe catches 23 on the upper sections of the molding strips 15 are then disengaged from the lower sections and the latter removed l'the strips 27 from the grooves 26 in the sides ofV the sash. The upper sashis removed in the same way after lowering it by disengaging the catches 25 from the lower seovtions 24 of the parting bead and remove the same, then slip the catches over the inturned ends of the metal strips 27.

It is to be understood that while the oonstruction shovvn and described is the best form at present known, various changes in the construction and arrangement may be made withoutvdeparting from the principles of therinvention.

I claim:

l. The combination with a window frame and a sash slidable therein, said sash having longitudinal grooves in its side edges; of sash cord attaching strips removably itted in the grooves iiush with the edges of the sash, said'st'rips having angular lower ends extending, beneath the bottom rail of the sash, and means on the window iraine engageable with said angular lower ends of the strips for holding said strips stationary relative to the sash.

2. The combination with a window frame and a sash slidable therein, said sash having longitudinal grooves in its side edges; oi sash cord attaching strips removably litted in the grooves iiush with the edges oi' the sash, said strips having angular lower ends extending beneath the bottom rail of the sash, and catches pivoted on the window sill and engageable with said angular lower ends of the strips for holding the same stationary relative to the sash.

3. The combination with a window frame and a sash slidable therein, said sash having longitudinal grooves in its side edges; of sash cord attaching strips removably fitted in the grooves flush with the edges oit the sash, said strips having angular lower ends extending beneath the bottom rail o'f the sash, and catches pivoted on the window sill and engageable with said angular lower ends of the strips for holding the saine statimiary relative to the sash, that portion of the bottoni rail of the sash which is engaged by the angular lower ends of the strips haring recesses which are entered by the catches when the saine are swung to engage said angular lower ends of the strips.

In testimony whereof I aiix inv signature.

WILLIAM s. BURKE.
