"This invention'i'elates to a multiple -=sash-window construction of the-louver type.

"The main objectof v the present invention is to provide a multiple sash *win'dow construction having novel means for opening and closing the sashes.

A more particular object of the present invention is to provide a multiple sash window construction having a plurality of banks of multip'le sash units, in which window construction there r are "springJnieans urging the "sashes toward open positions and which window construction further includes amanually operable mechanism for closing the sashes of all the banks against the resistance of the spring means.

Various other objects will beapparent from the following description .taken in connection with the accompanying drawings wherein:

"Figure .1.is a front view? in elevationof a multiple bank window frame construction incorporating the concepts of the present invention;

Figure 2 is a fragmentary sectional view taken along line22 ofFigure 1;

Figure 3 is a fragmentary verticalsectional view taken along line'3-3 "of Figure 1 andshowing the sash-operating mechanism;

'Figure '4 "is a vertical ssectional view taken along line 4-'-4 of Figure 1,showingr:the tension springs for: urging the sashes towardi theirxopen position Figure 5 is-a view similar to :Figure 4, but showing the sashes: in their open positions;

Figure 6 is a fragmentary horizontal view taken along line 6-E of Figure 4.

Referring to the .accompanying drawings, wherein similar reference characters designate similar. parts throughout, the arrangement in Figure 1 includes a window frame, generallyentitled 9, having a sill ll, ahea'd I3, jambs l5 and I! and mullions l9 and 2|. Framesflis thus divided for the reception of threebanks of sashes, generally entitled- 23, 25-and 21, which" are adapted to be operated in unison.

The sashes of each bank are mounted for swinging movement about 'horizontalaxes. The manner of swingably mounting -the'sashesmay take many forms, but the preferred form is shown inFigures 4, 5-and 6. As shown in Figure 4, each sash is swingably connected to the window frame: by atipair oiarmplatesfl; only one of 2 which is sh-ownfor 'eaehsash, each armplate being'pivotally'mountedat its-outer or upper-end toits sash *and being -pivotally connected at"3i to the associated jamb or'mullion depending upon the location ofthe-armplate. Each'sash is also connectedto-the window frame' by-a pair of sash plates --33, onlyone-o'fwhich is shown for each sash each sash plate'being fixedly connected-at one or itsends to theupperend of its sash -and being pivotally connected at its opposite end at 35 to a shoe-36 which i's fixedly securedl toa contihuous traveling -track 39 slidablyreceived Within a channelprovided'in the associated jamb or mullion depending upon the location' of the particular continuous traveling track. As is apparent 'from iF igures i and 5,*the traveling tracks interconnectthe sashes of each bank sothatthe sashes swing i in unison 1 from open l to closed positionsand vice versa.

'Each sa'sh-is urged "toward" its open position by a pair of tension springs 4| connecting sash plates- '33 "to pivots '3l "mounted on' the iambs or muliions. 'Only"one tensiomspring is shown for eachf sash. The tension "springs are obviously under te'nsion in the positions in which they are disposed in -Figure 4 andare also under tension, but of -a lesser 'degreegin the positions disclosed in 'Figure 5,-=so that-the-sa'shes arefirmly *disposed in their open positions.

Sash-operating mechanism is provided for closing -the banks of sashesin unison with 'one another at against the *resistance of *the tension springs 4i and for =progressively releasing the sashes efor GDEIIiHgmQVemEHt under the influence of i tension -springs 4|. 'This operating mechanism is best shown'in- Figures 1, 2 and '3 andmomprises "-a common -cable "drive shaft *43 rotatably extending through the mullions l9 "and 2 and into jambs t5 and I! and being rotatably supported in these variousmembers bysuitable bearings 45 (see *Figure 2). Cable drive shaft 43 hassecured thereto therealong cable spools 41 disposed-adjacent the jambs and mullions and carrying*cables 49,-=each being secured atone end to its spool and atthe other *endto thelower end of' theassociatediower sash by-a screw-'5 I.

For rotating -cor'nmon "cable "drive shaft 43, there is provided an encased worm gear drive 53yincluding a worm-wheel 55 secured to cable drive-shaft13 1 (seeFigurefl) and a worm '51 in driving engagementwith worm wheel 55. Worm gear drive 53 is mounted on sill ll by a suitable bracket 59, compare Figures 2 and 3. Worm 51 is mounted on a vertical drive shaft 5| extending through the sill H and down into a wall 63 below the frame 9 and connected by a universal joint 65 to a drive stud 61 mounted in a crank box 59 provided in wall 63. The drive stud has a depending non-circular end which is adapted to fit into a crank and by which the worm drive shaft 6! can be rotated to thereby rotate cable drive shaft 43. It is obvious that the worm gear drive 53 is a self-locking drive in that it can not be driven from the worm wheel to the worm but only from the worm to the worm wheel and therefore the sashes will remain in any position in' which they are adjusted by rotation of cable drive shaft 43.

The operation of the Window frame construction is as follows. In the position of the parts shown in Figure l, the tension springs ii are under considerable tension urging the sashes to swing outwardly to the positions shown in Figure 5. A suitable crank not shown can be insorted into the crank box and through the mechanism previously described, the cable drive shaft 43 can be rotated in a direction to unwind the cables 49 from the cablespools d? to progressively release the sashes for outwardly swinging movement. Although the sashes are shown in their completely open positions in Figure 5, it is obvious that the cranking operation could be terminated at any point and the sashes would remain in such position because of the non-reversible drive through the worm gear drive 53. When it is desired to close the windows, the operating crank is again inserted into the crankbox and the drive stud rotated to reversely rotate the cable drive shaft and wind up the cables 41 pulling the sashes inwardly so as to close the sashes. It is obvious that since the sashes are interconnected vertically by the traveling tracks 39, and horizontally by the common cable drive shaft 43, all the sashes of the entire window con struction will move in unison from open to closed positions.

Although two tension springs have been disclosed for each sash, it is contemplated that a pair of very heavy coil springs could be connected at one set of ends to the opposed tracks of a bank of sashes and at their other set of ends to the jambs or mullions, thereby providing only two springs for each bank of sashes. Such construction is to be considered an equivalent of that shown in the drawings.

By the present invention, a window frame construction has been provided including a plurality of sashes all operable in unison, said sashes being readily opened and closed by the simple operation of a single mastercrank which can be inserted into the crankbox 69.

Although a worm gear drive has been shown for cable 49, the invention is not intended to be limited by this disclosure since there are many other types of possible operators, including screw, slide, etc. which may be considered as equivalent to the worm gear drive; Furthermore, the operator for the cable can be mounted in various places about the window, and the mounting on the sill of gear drive 53 is not intended to be a limitation but only illustration of a practical application of the present invention.

While I have shown the preferred form of my invention, it is to be understood that various changes may be made in this construction by V 4 those skilled in the art without departing from the spirit of the invention as defined in the appended claims.

Havin 'thus described my invention, what I claim and desire to secure by Letters Patent is:
