2 Claims. (Cl. 160-101) This invention relates to a window construction and more particularly to a window construction having builtin storm and screen protection.

An object of this invention is to provide a window construction in which storm and screen inserts are removably built into the structure and between a pair of sliding window members and the inserts are concealed from both inside and outside of the window.

Another object of the invention is to provide a doublehung window construction including upper and lower window sashes which are arranged with a space between their meeting rails so that a pair of vertically disposed inserts may be placed therebetween to provide the desired storm or screen protection depending upon the structure carried by the inserts.

A further object of the invention is to provide a window construction as dened in the preceding paragraph wherein the vertically disposed inserts are arranged in abutting relation in vertically disposed channels positioned between the upper and lower window sash with one of the sashes positioned to form part of said channels and being removable to enable placement and removal of the inserts in the channels.

A further object of the invention is to provide a window construction including a window sash which is removably mounted in the window framing by means which include a friction strip extending along one sash stile in sliding engagement with the adjacent window jamb, and means carried by the sash stile for moving the friction strip to a position to permit withdrawal of the window sash and to additionally vary the friction engagement between the friction strip and the jamb to provide proper counterbalance of the sash.

The objects of the invention generally set forth together with other ancillary advantages are attained by the construction and arrangement shown by way of illustration in the accompanying drawing, in which:

Fig. 1 is a vertical elevation of a window construction including the window framing, looking from the inside out, and with the lower sash slightly raised;

Fig. 2 is a horizontal section taken generally along the line 2-2 in Fig. l;

Fig. 3 is a vertical section taken generally along the line 3-3 in Fig. l but with the lower sash closed;

While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail an illustrative embodiment of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiment illus- 2,969,834 Patented Jan. 31, 1961 fice trated. The scope of the invention will be pointed out in the appended claims.

The window construction as shown in Figs. 1-3 comprises a lower window sash 1 and an upper window sash 2 having spaced apart meeting rails 3 and 4, respectively. The upper Window sash 2 has Stiles 5 and 6 at its sides. The stile 6 has vertically extending grooves 7 which slidably engage projectio-ns 8 formed in a block 9 forming part of one side jamb. The groove 7 and projections 8 constitute coacting means for slidably confining the sash stile 6. The sash stile 5 carries a vertically extending friction strip 10 Which is generally U shaped and has one leg 11 embedded in the stile 5 as by providing a vertically extending sawcut therein. The friction strip is arranged to be somewhat exible and may be made of aluminum or other suitable material. A base part 12 of the friction strip 10 is arranged to slidably engage a guide surface `13 formed in a block 14 forming part of the side jamb, The guide surface 13 tapers inwardly away from the sash stile 5. The base part 12 of the friction strip and the block 14 have slidably interengaged parts, as indicated at 15, to define coacting means for slidably confining the sash stile 5. Another leg 15a of the friction strip extends vertically along the front of the sash stile 5 for a` purpose more fully set forth hereinafter.

The lower Window sash 1 has stiles 16 and 17 at the side thereof, and the stile 17 is slidably confined to a vertically extending side jamb section 18 by coacting means, indicated at 19, comprising interengaging grooves in the stile 17 and projections on the jamb section 18. The stile 16 carries a friction strip 20 generally similar to that carried by the upper window sash 2 and has a leg 21 embedded in the stile 16 `and a base part 22 at an oblique angle to the leg 21 which slidably engages a surface 23 formed in the side jamb member 24 and which tapers inwardly away from the sash stile `16. Another leg 23 of the friction strip 20 extends vertically along the front of the stile 16, and the connection thereof to the base part 22 of the friction strip forms, with a notch 26 in the side jamb member 23, coacting means for slidably confining the stile 16.

As shown in Fig. 3, the meeting rails 3 and 4 are spaced apart to provide a space through which a pair of vertically displaced inserts 27 `and 28 may extend in abutting relation. These inserts may comprise a surround frame formed of a U-shaped, metal channel and receive panels of glass, such as indicated at 29, or a section of screen, such as indicated at 30, each of which may be secured to the surround frame by being embedded in suitable material.

The right-hand sides of these inserts 27 and 28. looking at Fig. 2, are confined in a channel extending vertically between the upper and lower window sashes. This channel is defined by the jamb sections 18 and 9 and a base jamb section 31 to which the jamb sections 9 and 18 are secured, the jamb sections 9, 18 and 31 forming a side jamb.

The left-hand sides of the inserts 27 and 28, looking at Fig. 2, are confined in the space between the upper and lower window sashes at one of their ,faces by the jamb sections 14 and 24 which comprise a side jamb and forming in part a channel which is completed by the stile 16 of the lower window sash 1.

As in conventional window construction, there may be a sill 32 from which the side jambs extend upwardly, and exterior trim members 33 and 34 also extend upwardly from the sill and partially over blind stop members 35 and 36 which engage and partially enclose the outer weather faces of theupper Window sash stiles 5 and 6. The other structure surrounding the window construction may include a conventional wall construction.

`It will be seen trom the foregoing that a pair of slidH -able window members have been provided with a space between their meeting rails so that a pair of vertically disposed inserts maybe disposed therebetween in abutting relation with each other, and the inserts are coniined by a window sash and cooperating side jamb structure.

In order to remove the lower window sash 1 so as to give access to the inserts 27 and 28 for removal thereof or to permit insertion of the inserts, the mechanism as shown particularly inFigs. 4 and 5 is provided. The friction strip is provided vwith a pair of vertically spaced, elliptical openings 40 and 41, as shown in Fig. 1. Associated witheach of these openings is a rotatable plugv42 rotatably embedded in an opening in the stile 16. This plug has anl exposed flange 43 which is circular so that portions thereof lie behind the friction strip" in order to confine the plug in the stile. Extending outwardly from the flange 43 is a T-shaped projection 44including a pair of legs 45 .and 46 of equal length and a cam section 47 having a slightly greater length than either of the legs 45 or 46. With this co-nstruction, rotation of the plug 42 in a clockwise direc'- tion, looking at Fig. 4, will carry the cam section 47 in a clockwise direction so as to ride against the edge of the non-circular opening 40 and function to pull the friction strip 20 away from the jamb surface 23 and clear of the notch 26 formed in the side jamb so that the edge of the window including sash stileg16V may be moved inwardly a distance suicient to then permit release of the coacting coniining means associated with the stile 17. The cam section `47 may be moved back generally to the position shown in Fig. 4 after the window sash is again put in place so as to return the friction strip 20 into sliding engagement with thel jamb surface 23 and behind the jamb notch 26. The rotatable plug `42 may also be slightly adjusted in either direction of rotation so as to vary the friction engagement of the friction strip 20 lwith the surface 23 in order to properly counterbalance the sash. I

A suitable key for operating the plug 42 is shown in Fig. 6 wherein a disc 4S has a handle 49 secured thereto, and the disc 4S carries four raised lugs 50 which may be placed against and interfitted with the raised, T-shaped projection 44 in order to facilitate turning of the lug.l

The structure shown in Figs. 4 and 5 is yalso utilized with lthe friction strip 10 associated with the upper window sash 5 to enable removal of the upper sash, and the openings in the friction strip 10 are shown at 51 and S2 in the upper sash 2. j

The structure for rendering the sashes removable, as well as adjusting the sliding action thereof with a minimum of force, renders it extremely simple for a person to remove or replace a window sash for purposes of cleaning the window glass or handling inserts 27 and 28.

It will be obvious that either screen or storm glass may be `carried by the inserts 27 and 2S, depending upon the season of the year, and it is possible to always have oneV insert provided with glass, as shown at 29, and to have two dierent, alternatively usable inserts at 27, one of which may have screen material, and the other glass.

I claim:
