ElmorrAi Schottenberg, Youngstown; Ohio; ass
signer, by mesne assignments; to R'epubllmSteeli t'iprporation, .Gleveland Ohio;...a,. cozpcraticm N mIersexv Application December 27, 1949, SeriaI'NGsBSJZIIZ This invention relatestolouvenwindows" of" thetype having ar-tier of hinged'sashes which in closed position are in a vertical plane and which may be moved totheir open positions byrevolving eaehsasli-ahoutiit's hinge; The invention relates more particularly to means for. me inting the sashes and for, opening and 0105.-
In-generahit is the object ofthis inventionrto provide means for opening and closing the sashes of a,-,10llVel. window of the type mentioned .which diff sifrom previous means known and which is sturdy in structure and relativelyinexpensivezto manufacture and assemble.
Amotherobject is to provide, such meansfwhich is pcsitive in action and durablein use.
A further object is the provision of such means which permits-thesimultaneous operation of a number-mi sashes on a window or, if conditions requirein; any particular-sash .orsashes-1 may be made permanently stationary; without affecting the operation of the other sashes.
A still further object of the invention is to provide a window of the type mentioned in which the top corners of the sashes are supported by sliding pivots mounted in vertical slots in the window jambs and bell cranks for moving the sashes or vents about said pivots to open and close them, the bell cranks being simultaneously operated by vertical connecting links, which links are in turn moved up and down by gear segments operated by pinions on a torsion shaft within the sill of the window, means being provided to rotate the shaft manually or otherwise.
These and other objects and advantages of the invention will be apparent from the following description considered together with the accompanying drawing in which:
Figure 1 is a perspective view of a louver window in accordance with an embodiment of this invention with the sashes thereof in open position.
Figure 2 is a perspective view similar to Figure 1 with parts removed to show the linkage system.
Figure 3 is an enlarged side elevational view, partly in section, of the left lower corner of the embodiment illustrated in the previous figures showing the arrangement and operation of the mechanical elements therein.
Figure 4 is a section along the line 4-4 of Figure 3.
Referring with more particularity to the drawing in which like numerals designate like parts, the embodiment illustrated comprisesa window frame having a lintel l I, sill l2 and jambs l3 and l4. The sill 'and jambs contain theoperatingi mechanismand are; therefore; preferably of a. hollowconstructiom- Thedlntel may or: may notb'eof hollow constructiom The plurality of sashes" 15 are. disposed: one
above the other within the. open area"v of the frame. Four or such: sashes: are; shownv iirthe drawings: shafts or rods- It; It that are seeuredfto the' upperendofthe-sashes'and which-project 'outward ly on either side thereof to. slidably? 'and 'pivotally" engage vertical slots H;- i'l in the ja'mbs;
Eac-lrsashis actuated by'a pair of hell cranks:
l8; ifl having-eachanextension arm Iii-projectition of'the jambs and verti'callymovable therein;
The lowermost bell cranks-attire bottompf the" jambs are each rigidly secured to a curved gear segment 24 by means of rivets 24a and 24b. These gears mesh with pinions 25, 25 at the ends of a horizontal torsion shaft 26. Said torsion shaft is disposed within the hollow portion of the sill l2 and is rotatably mounted in bearings 21, 21. Rotation of the shaft is efiected by means of a worm gear consisting of worm wheel 28 secured to the shaft 26 and a worm 29 engaging the wheel on a crank shaft 30 of a crank 3|. The crank handle 32 is adapted to be manually operated and is disposed on the outside of the sill. However, should it be desired to operate the device by an electric motor, for example, the worm 29 could be connected to the power shaft of such a motor located within the sill with suitable operating switches disposed on the outside at any convenient place.
Each gear segment 24 has a shoulder 33 at one end which is adapted to abut an inner wall 34 of its respective jamb when it is in its extreme position to close the sashes. The other end of the rack gear is provided with another shoulder 35 which abuts a projection 36 when the rack is in its opposite extreme position to open the sashes.
Guide lugs 31 project from the bearings 21 to prevent the segments from running on their pinions in the direction of the bearings. Other guide lugs may be provided where necessary.
In operation the sashes are opened and closed merely by turning the crank handle 32 which Each-sash is provi'dediwitir a" pair of i causes rotation of the torsion shaft 26. Said shaft, in turn, rotates the pinions 25, acting upon the gear segments 24 as a lever. Since these gear segments are secured to the lowermost of the bell cranks I8 they cause them to turn about their apex pivots which motion is transmitted simultaneously to all the bell cranks through the links 23. When the rotation is in one direction the extension arms IQ of the bell cranks are forced upward and inward which forces the sashes upward and inward. This rotation is made possible by the fact that the sashes are attached to the jambs by means of the rods or shafts which slidably operate in the vertical slots I'l. When the opposite rotation is effected the extension arms 19 are forced outwardly and downwardly which permits the upper parts of the sashes to drop within the limits provided by the slots l1 and at the same time the lower portion of the sashes are forced outwardly in the position illustrated in Figures 1 and 2.
If it is desired to immobilize any oneor more of the sashes, they are simply secured in the closed position and disconnected from the extension arms of their corresponding bell cranks.
Iclaim:
1. A louver window comprising a frame having a sill, a lintel, jambs and a tier of sashes in the open area of the frame, means for slidably and pivotally supporting the upper end of said sashes on said jambs, upwardly projecting bell cranks for each sash pivoted to the jambs, said bell cranks having upwardly directed extension arms pivoted to the sashes and additional relatively shorter arms projecting in the opposite direction, a vertical travel link for each jamb with the lower end thereof pivotally connected to each of said additional arms, gear segments rigidly and ecccntrically secured to said shorter additional arms of the bell cranks with respect to the bell crank pivots of the lowermost sash, pinions meshing with the gear segments, a torsion shaft carrying said pinions, and means for r0- tating the torsion shaft.
2. A louver window comprising a frame having a sill, a lintel, jambs and a tier of sashes in the open area of the frame, means for slidably and pivotally supporting the upper end of said sashes on said jambs, upwardly extended bell cranks for each sash pivoted to the jambs, said bell cranks having upwardly directed extension arms formed with depending lugs pivoted to the sashes and additional relatively shorter arms projecting in the opposite direction, a vertical travel link for each jamb pivotally connected to the extended end of each of said additional arms, gear segments secured to the said additional arms of the bell cranks of the lowermost sash, pinions meshing with the gear segments, a torsion shaft carrying said pinions and having its axis at right angles to the axis of said gear segments, means for rotating the torsion shaft, and abutment means associated with said gear segments for limiting their movements substantially within the operative range of the bell cranks.
