Referring more in detail to the drawings:

1 designates a window construction comprising a window casing or frame 2 including a sill 3, side jambs 4 and a header 5, each of which is arranged to provide a blind stop 6 defining the window opening 7 and having an inwardly facing shoulder 8. In this form of the invention, the window opening .7 is relatively large and is adapted to be closed by a..sing1e sash 9 which due to the size would be inconvenient to bodily move to and from the window opening. Therefore, it is preferable that the window sash be pivotally mounted in the window opening.

The window sash 9 includes a frame 10 in which a pane 11 is, mounted in a conventional manner, said frame having inner and

outer faces

12 and 13. The sash frame is of such a size that the outer surfaces or edges 14 are slightly spaced as at 15 from the inner edges 16 of the stops 6 whereby the sash frame is movable through the window opening 7. The sash frame is pivotally mounted on trunnion members 17 rotatably supported in brackets 18 suitably secured by fastening devices such as screws 19 to the window frame, as illustrated in Fig. 6. Seal strips 20 are secured to the inner and

outer faces

12 and 13 of the sash frame adjacent the periphery thereof whereby the sash is reversible in the window frame, if desired, said sash being freely pivotablein the window opening. In order to secure the sash in weatherti-ght relation to the frame, an auxiliary frame 21 is mounted in the window frame in sealing engagement with theseal strip 20 on the inner face of the window sash, and also in sealing engagement with a resilient seal strip 22 on the face 8 of the stop 6 adjacent the inner edges thereof around the window opening.

The frame 21 has a peripheral wall 23 with an edge 24 adaptedto engage the seal strip 22 when the wall 23 is in position surrounding the Window sash frame. The edge of the wall 23. opposite the edge 24 is turned inwardly whereby the auxiliary frame is substantially L- shaped in cross section with the inner wall 25 terminating in a lip 26 adapted to engage the seal strip 20 around the inner face of the window sash frame, the auxiliary frame being such and related to the

seal strips

20 and 22 whereby there is a weathertight seal completely surrounding the window sash and window opening.

The auxiliary frame is held in place to provide the weathertight seal for the window opening by means of a plurality of magnetic securing devices 27. The securing devices 27 each include housings 23 having laterally spaced

side plates

29 and 30 of mild steel or other permeable material. The

plates

29 and 30 are supported by non-magnetic material which in the illustrated structure is in the form of spacers 31 therebetween whereby the spacers 31 and

plates

29 and 30 form through passages 32 to slidably mount bar type permanent magnets 33. The housings are positioned whereby the passages 32 are perpendicular to the face 8 of the blind stop 6, said housings preferably being mounted on the frame 21 by means of suitable fastening devices such as bolts 34 of nonferrous metal with a spacer strip 35 of non-magnetic material between the plate 30 and the peripheral wall 23 of the frame 21 whereby the side plate adjacent said frame 21 does not contact any permeable metal. The housings are fixed on the auxiliary frame 21 at suitable spaced intervals thereon, and in the form illustrated in Fig. 1 there are eight such housings arranged around the frame. A plurality of mild steel plates 36 are fixed on the face 8 of the blind stop 6 and positioned whereby one registers with the passage of each of the housings and serves as an armature plate 36 in the magnetic securing device. The armature plates 36 are preferably secured to the window frame or blind stop by means of suitable fastening devices 37 such as screws and the like.

When the frame 21 is positioned surrounding the window sash with the edge 24 and lip 26 sealingly engaging the

sealing strips

22 and 20 respectively, the end edges 38 of the

side plates

29 and 30 engage the front face 39 of the respective armature plate 36. The bar type magnets 33 each have a size to substantially fill the passage in the respective housing and engage the side plates and are slidably moved into the passages until the inner ends 40 of the magnets engage stops 41 which provide for a slight spacing between the inner ends 40 of the magnet and the armature plate 38. In the illustrated structure, the stop 41 is in the form of a non-ferrous pin extending across the inner end of the passage 32. The magnets 33 are preferably formed of sintered material sometimes referred to as ceramic magnets or other relatively strong permanent magnet of small size. positioned between the

side plates

29 and 30 and spaced slightly from the armature plate 38, the magnetic flux is materially increased providing a very strong attraction to-firmly hold the auxiliary frame 21 relative to the window frame or casing. When it is desired to open the window, the individual magnets 33 may be pulled from the housings with little effort which is a mere fraction of the force holding the housings relative to the armature plate, and when the magnets are removed from the individual housings, the auxiliary frame may be lifted and removed from the window casing freeing the window sash for pivotal movement as desired. With the sealing strips 2t? on the opposite faces of the sash frame, the sash may be reversed and the auxiliary frame positioned and the magnets inserted to provide a'weathertight seal for the window opening and sash, positively holding the window sash in position.

In the-form of the invention illustrated in Figs. 7 and 8, the window opening 44 defined by the casing 45 and blind stop 46 thereof is sufl'lciently small whereby the sash and frame 47 may be easily lifted and moved. In this form of the invention, the inner face 48 of the stop 46 has a seal strip 49 around the edge of the window opening and there are a plurality of spaced armature plates 59 secured to the face 48 of the stop and spaced around the window opening for alignment with passages 51 through magnet housings 52 secured to the sash frame 47.

In the modified form of the invention, the sash frame is larger than the window opening 44 whereby the frame overlies seal strips 49, the sash frame preferably having ribs 53 extending from the inner and outer faces 54 and 55 of said frame to sealingly engage the strips 49 on the stop 46. While the structure shown in Figs. 7 and 8 is such that the sash is bodily removable from the casing, it is to be understood that it could be supported for swinging movement relative thereto or other bodily movement relative to the window opening. In the structure illustrated, the sash frame 47 is formed of wood or other non-magnetic material whereby the housings 52 may be secured thereto with one side plate 56 engaging the wood portion of said sash frame. If the sash frame is made of metal, then the plate 56 should be spaced therefrom by a suitable spacer of non-magnetic material. The plate 56 is supported in spaced relation to the other side plate 57 by means of spacers 58 of non-magnetic material to form the housings 52. The housings 52 are suitably secured to the sash frame by fastening devices such as screws 59 of non-ferrous metal which extend through aligned holes in the non-magnetic spacers 58 When respective armature plate mounted on the blind stop 46. When the magnets are removed from the respective housings, the sash may be bodily removed from the closing position relative to the window opening. When it is desired to close the window, the sash is moved into position with the ribs 53 engaging the seal strip 49 and with the passages 51 of the housings 52 registering with the armature plates 50 and the magnets are then slipped into the passage of the respective housing until the ends 61 engage the stops 62 at which position the magnetic ilux is increased whereby the magnets firmly hold the sash in place.

It is to be understood that while I have illustrated and described one form of my invention, it is not to be limited to the specific form or arrangement of parts herein described and shown except insofar as such limitations are included in the claims.
