LOCK FOR STORM SASHES Filed July 11, 1952' BY w A M' Patented Sept. 15, 1953 4UNITED STATES PATENT OFFICE LOCK FUR. STORM SASH Irving H. Schwartz, Philadelphia, Pa. Application July 11, 1952, Serial No. 298,328

2 Claims.

1 f l Storm windows of the self storing type include a triple track attached to the window frame and in which are adapted to be slidably mounted the usual inner glazed sash, outer glazed sash, and the screened sash. Also retaining means are provided for retaining any of said sashes in any position to which it may be moved.

One object of my invention is to produce an limproved sash retaining device whereby the sash may be locked in any position to which it is adjusted.

A further object is to produce an improved sash retaining device which is light, inexpensive, and easy to operate.

A still further object is to produce a sash retaining device which is carried by, and movable with, the sash and which frictionally engages a wall of the track in which such sash slides.

These and other objects are attained by my invention as set forth in the following specication and the accompanying drawings in which:

Fig. l is an elevational view of a window the lower, inner, sash of which is provided with a sash retaining device embodying my invention.

Fig. 2 is an enlargement of the bracketed portion of Fig. 1.

Fig. 3 is an enlarged sectional view looking in the direction of line 3-3 on Fig. 1.

Fig. 4 is a fragmentary side elevational view of the storm sash frame shown detached, with the retaining device omitted.

Fig. 5 is an enlarged transverse, sectional View looking in the direction of line 5-5 on Fig. 4.

In Fig. l there is shown the inner, or room side,

of a wall of a room which is provided with a window opening of the usual type. The window opening is closed by means of the usual, inner and outer, vertically slidable, glazed sashes which are conventional in structure and operation and are therefore not shown nor described. For the purpose of this invention, it is merely necessary to refer to the conventional window frame, or to the wall defining the window opening, regardless of whether such wall be of wood, of masonry, or of other construction, as the window frame |2.

In order to adapt the window frame to a standard size storm sash, an adapter I4, of a generally U-shaped cross section, is secured to the window frame by means of screws or the like, not shown. The limbs i6 of the adapter frame are adapted adjustably to receive therebetween the inner and outer walls and 2| which form part of, or are carried by, the storm sash triple track to be later described. The

walls 20, and 2|, or either of them, is suitably secured to the limbs I6 of the adapter frame I4 by means of screws or the like, not shown. By this construction, the window opening, or the window frame I2, is adjusted, within reasonable limits, to receive a standard size storm Window thus making it unnecessary to fabricate the storm windows in many sizes and to close tolerances. The construction described also facilitates the mounting of the storm windows.

The inner ends of the walls 20 and 2| cradle between them an abutment wall 22 which serves as a backing for the Wall 24 of the sash receiving track. The track itself is formed of inwardly projecting

walls

26, 21 and 28 which, in cooperation with the extension 29 of the outer wall 2| of the adapter frame, define

channels

33, 34 and for respectively receiving the frames of the inner and outer glazed sashes and the screened sash.

The frame of the storm sash itself includes a body portion 36 the inner side of which is provided with a relatively narrow channel 38 for receiving the edge of the glass 39 and with a relatively large channel provided with gaskets 40 for engaging the marginal portion of the glass in a cushioned and tight manner, as best shown in Fig. 3. The opposite or outer, side of the sash frame is provided with a channel 42 for engaging one of the

walls

26, 21 or 23. It will be noted that the edges of the walls defining channel 42 converge as at 43 so as to have a line contact or bearing on the

wall

26, 21, or 28 engaged thereby and thus reduce friction and the tendency to bind.

The sash retaining device of my invention includes a plate-like member a portion 44 of which is adapted to engage the inner face 45 of the sash frame, and the inner edge of which is bent outwardly as at 46 so as to engage the inner edge 41 of the sash frame. The plate like member also includes a dished portion 48 from which is struck an outwardly projecting tongue 66 and the outer portion 52 of which is adapted to engage the inner, or room side face of adapter wall 20 as at 5|. The wall 20 of the adapter frame is provided with a marginal notch or hole 54 through which tongue is adapted to pass to engage the inner, o1' room side, face or wall of the track 28. See Fig. 3. The retaining device also includes a bolt or screw 56 which is adapted to pass through an opening 51 in the dished portion 48 and to engage a tapped opening 58 in the body 36 of the sash frame.

When it is desired to raise or lower the storm sash 60, the screw 56 is backed oi until the tongue 50 is disengaged from notch 54. When the sash has been moved to the desired position, the screw 56 is tightened to force the tongue 50 into tight engagement with track 28 and to force the outer, or right hand portion, of the dished member 48, as viewed in Fig. 3, into tight engagement with the room side of wall 20 of the adapter frame as shown at 5I. The sash is now locked tightly in position.

It will be seen that the retaining device is small, light, compact and inexpensive, that it is easy to operate, and that, being carried by the sash it can not be mislaid. Also, the part of the retaining device which engages the track 28 or the wall 20 does not have to enter a slot or hole but can engage any portion of the fixed surfaces' which correspond to the position of the sash. It will also be seen that the contact, at 5I, of the long edge (see Fig. 2) of the portion 52 of the retaining device, and; the contact of tongue 50 with track 28, produce a stable engagement sufcient to prevent rattling or slipping of' the sash.

What I claim is:

1. For use in connection with window construction of the type which includes a window frame, an inwardly projecting track carried` by said frame, a sash for closing the Window opening, and a pair o f outwardly projecting walls defining a channel for receiving said track with said walls disposed alilrlg` the opposite sides of said track, a lock for securing said sash to said window frame, said lock including a plate, a tongue projecting from said plate in the direction of said track, there beingy a passage formed in the adjacent one of said pair of walls through which said tongue is adapted to pass to engage said track, said platehaving an` opening therein and said sash frame having a tapped hole therein, and a bolt having a reduced portion adapted to pass through the opening in said plate to engage said tapped hole and having an enlarged head adapted to bear on said plate to press said tongue against said track.

2. For use in connection with window construction of the type which includes a window frame, an inwardly projecting track carried by said frame, a sash for closing the window opening, and a pair of outwardly projecting walls dening a channel for receiving said track with said walls disposed along the opposite sides of said track, a lock for securing said sash to said window frame, said lock including a plate, of a size suiiicient to overlap at least a portion of the window frame and at least a portion of the sash frame, a tongue projecting from said plate in the direction of said track, there being a passage formed in the adjacent one of said pair of walls through which said tongue is adapted to pass to engage said track, said plate having an opening therein and said sash frame having a tapped hole therein, and a bolt having a reduced portion adapted to pass through the opening in said plate to engage said tapped hole and having an enlarged head adapted to bear on said plate to press said tongue against said track and to press said plate against said sash frame and against said window frame.
