and in Germany February 4, 1930 6 Claims. (01. 139-72) 7 1. My invention-relates to sliding windows for use the ground floors of .dwellingseand business establishments, the window when lowered being received. in a shaft adjoining the, cellar. As

3:115 these windows are constructed .of large dimensions,-.the,substantial masses of metal forming .the sash conducts away the heatand with a heavy frost the metal parts sweat at the side facing theroom.v

.Further, withsuch arrangements good packing .of....the closed window, especially at the sidenext the cellar, is of particular importance. The warm air atthe basement passes very rapidly in winter through untight joints and the room is quickly cooled. Further, with defective packing disagreeable odors readily pass through the shaft. The invention avoids the drawbacks inherent in known constructions. l

Inthe present construction the sliding windows have a metal frame-work carrying the I glass-pane, said frame-work having closed inwill .serve as a shaft into which the window'is -lowered.vv

sulating chambers alongall the sides and edges of said pane which prevent theconduction away iof the heat. r

Secured to the underside of the sash is an intermediate'frame also of box formation and partitioned intoseveral air chambers, with or with ,out auxiliary chambers; a frame ,arranged ;be-

neath said intermediate frame forming a chamber acting as an insulating space. j

. Further details ,of the, invention are hereinrafter described and illustrated in the accompanyingdrawing inrwhich Fig. 1 shows diagrammatically the window assembly, in cross sectionj h .'Fig.. 2:is aside elevation of the sash.

. Fig.3 is a section on the line IIgI-III ofFi Fig. 4 is a section ontheline of Fig. 2. Fig.- 5 is asection showing the upper part I of the window sash in, lowered position.

Fig. 6 is a cross-section showing another form I of the lower frame member and packing means.

The floor 3 is formed in the plane of the window with .a slot 3'x-which iscontinued in downward direction as a shaft 4. In the embodiment illustrated it is assumed that the cellar of the house with the lower part of the window sash 2 is a bracket 5 engaged bya rope 5' actuated through. gearingby a motor inorder to .'raise and lower thewindows mechanically (Fig. l)

The window pane 1 is fitted in the sash 2 which embracesall four edges of the frame and is'of boxlike formation. There are thus provided at both sides of the plane of the pane cavities 21 which are closedon the street side andonthe room side, and also at the faces which bearon the pane and serve. as insulating spaces.

At the upper side of the window there is con nected with the sash 2 a cross frame: 28 which is closed on top by a plate 30 carrying the packing strips. 30, which, when,. the windowis'closed,

bear against two sealing faces 31 on the tranmembers the middle one '37- of which is of T formation and provided with cranked flanges (Fig. 4). These members areguidedin suitable recesses in thelining member 34 fixed to the masonry .35 with the. interposition of a filling medium. r

This style of guidance ensures easy andexact translatory movement of the window an'd also tight sealing. The-tortuous crevices resembling those presented by labyrinth packings prevent coldair fromstreaming in from outside.

In the lining member 34there'are-also pro- .vided closed chambers 33' acting as insulating spaces. I a

.On the underside. of the window there is secured-to the-sash 2 an intermediate frame 6 also of box formation, the cavity of which intermediate frame is partitioned'by awall 24 of wood or other poorly conducting material intotwo chambers 22, 23 acting as insulating spaces. On

the room side or at both. sides there. is fixed. to

. the auxiliary frame 6 a supplemental frame (Figs. 3 and 6) which forms an auxiliary in-' sulating chamber 7.

A plate 9 connected withthe frame 6 serves as an upper closure for a chamber 10 which is bounded by. lateral walls 10 and a. lower transverseplate 10" connected with the bracket-5.

At the'basej of the chamber 10 there are arranged for-example between spring contact clips electrical heating resistances 25. To' conduct the current there serves a conductor26 leading toa contact .27. by means of which for example a heating current can be switchedon or off fromthe dwelling. room. For the supply, of current there may naturally also bev used other suitable I arrangements; for example, a contact stud may there are provided angle bars 8 which project at both sides above the frame. In the space bounded by the vertical flanges of the angle bars 8 (Fig. 3) there are fitted-at both sides grooved packing strips 11 of rubber or the like. Additional angle irons 12' servingas carriers for packing tubes 13 are connected with the lateral walls 10 of the box frame 10.

The slot 3 is lined on both sides with bars 14 which each merge on top into a T-piece 16. One limb of the T-piece projects over the slot 3 and is provided on the upper side with an inclined face 15 which facilitates therunning offof water. The T-piece 16 has a downward projection 16' (Figs. 3 and 5) or an inclined face 16" (Fig. 6).

When the window is closed, that is, raised, the rubber packings l1 engage the projections 16 of the bars 14. Further, at the same time the tubular packings 13 bear against the inclined faces 1'7of the bars 14.

In this way there are formed on both sides closed insulating chambers'20 of which each is bounded by the outer walls of the bar 14, by the wall 10 of the frame 10, and on top and bottom by the packings l1 and 13. These insulating chambers prevent exchange of air and heat between the room closed 'by'the window and the shaft or cellar. I

In the modified construction accordingto Fig. '6 each T-piece 16 is provided with an inclined face 16". The plate 9 has laterally projecting parts 18 upon which rest carriers 19 for the packing tubes 21'. In the raised or'closedposition of the window these "tubes are pressed against the faces 16". The arrangement'of the lower packings 13 is the same as in the construction according to Fig. 3. In this case also, in the closed position of thewindow' closed insulating cham- Zbers are formed by the double packing at both sides of the window, which chambers pack the window reliably from the underside and prevent draughts and penetration of odors from the cellar.

In the construction according to Fig. 6 the boxes '7 have projections which are inclined in correspondence with the packing faces 16" and which act as a stopon lifting the window;

The bars l l'also insulate the chambers 20 relatively to the masonry. Theyoverlapthe sill at the outer side and close the slot 3 at the inner side so that between them andthe masonry auxiliary insulating chambers 14' .are provided.

With the windowfully open the plate 30 bears against the T-shaped projections 16 of the bars 14 as shown in Fig. 5, so that-the shaft is covered.
