7 Claims. 20-53) The present invention relates to a window construction and refers more particularly to a window comprising a window frame and pane elements 'tiltably supported in said frame on substantially horizontal axes extending laterally'of said frame.

s An object of the present invention is to provide a windowof the above type with Weatherstrip means. I

Another object is to provide means for tilting one or more of said pane elements, the means being operable by a single actuating lever or the like and operative on said pane elements atboth ends of the latter, the means further being operative to tilt pane element to which it is connected by the same amount and at the same time.

. Yet another object is that,if, through abuse or other accident, the tilting means becomes damaged in such a way as tobe wholly inoperative, the pane elements will by gravity assume a vertical, closed position. I

A further object is to provide means associated with said tilting means and actuated by the same actuating means for'actuating said Weatherstrip means into sealing relation with said window frame after said pane elements have been actuated into substantially vertical and closed relation, and for actuating saidweatherstrip means out of said sealing relation previous to tilting said pane elements. 7

Another and further object is that the sealing action of said Weatherstrip means shall oonstitute a lock means preventing relative motion between said pane elements and said window frame.

Still another object of the invention is to provide a window frame in which the four elements constituting the sides of the rectangular frame shall be disconnectable from one form for convenience and economy in shipping.

Other objects will in part be obvious therefrom and in part will be pointed out as the description proceeds. I

In the accompanying drawing, in which is shown one of the various possible illustrative embodimentsof this invention:

Figure '1 is' a front elevation of a bodying the present invention.

Figure '2 is a sectional view on the line 2-2 of Figure 1.

window emfRefer-ring now in detail to the drawings, my im- 1 proved window [0 comprises thev substantially rectangular window frame IOA, the latter comprising the side members I013; H,--header l2 and sill l 3, all preferably of channel sheet met-a1 construction. The side members HlB, II have surfaces 13A, I3B finished square with their length, and portions projecting beyond said square finished portions and formed with slots I3D. The portions I30 project through slots 13E in header l2 and sill l3. Wedges I3F are'driven into slots 3D to draw the square finished portions l3'A, |3B against the sill l3 to detachablyconnect the three sides together into the substantially rectangular window frame IDA. The frame can thus be shipped completely knocked down at a considerable saving of shipping space, and assembled on thejob.

The bars l4 tending longitudinally thereof, and bolts 14B extending perpendicularly from side members IOB extend through slots I 4A and carry the nuts M C. whereby the bars 14 are vertically slid-ably mounted in the side members HiB. Bars [4 are further formed with the slots MD, which are so located relative to one another as to constitute a rack l5.

A circular gear I6 is rotatably mounted on stud l! on side member IDE and is operatively connected to handle 18, and to bar Hi, the teeth of gear I 6 engaging the rack l5,so that rotation of handle l8 rotates gear lb to slide bar l4 relative to side member 103.

.Bars [4 are formed with a plurality of long openings I9 and comprise the racks 2!! along one side of the openings and facing thereinto.

The pane holding elements or sash 20A comprise at each end the side bars 2013 having an elongated body of modified H cross section, the latter comprising a bight or U-shaped portion 200 and a guide ledge portion 20D extending in a common plane with and integral with one of the arms 20E of the U portion 200.

Gears 2i engage the racks 2|] of bars M in the side members IBB, H, and are securely mounted on the .pivot shafts 22 of pane holding elements 20A, the shafts 22 being journaled in the side members lllB, H at 22A. Firmly mounted on gears 2| are the parti-cylindrical segments 23 forming part of the window locking and weatherstrip actuating mechanism 24 to be described hereafter.

The window panes '25 are made up of two sheets of glass separated by spacer strips 25A. Straps 2-6 rotatably connect the pivot shafts 22 to the other arms 26A of the U-shaped portions are formed with the slots" MA ex- 3 20C opposite the arms 28E in the plane of the guide ledge 20D. The .panes 25 are frictionally and resiliently held in the U-shaped portions 20C by the insulating material 21 located under compression between panes 23 and portions 200.

The following means are provided for causing simultaneous and equal motion in the same direction of the bars l4-mo-un'ted in each of the side members IOB of window frame MA.

A shaft 28 is rotatably jou-rnaled as at 23A in both side members 10B, I, extending therebetween inside the sill I3. Gears 29 keyed to shaft 28 near each end thereof engage the racks 33 of bars l4, so that sliding actuation of the bar It illustrated in Figures 3, 4Vand 5 and on the left of Figure 1 rotates shaft 28 and thus slidingly actuates the similar bar l4 nthe right of Figure 1 by the same amount in the same direction at the same time. i The locking and weather strip mechanism 24 previously mentioned comprises the sleeve bearing 3| and the sleeve 32 slidably mounted on' pivot shaft 22 and in bearing 31. Segr'nent 23 is formed with the arcuate cam slot 33, and pin 34 mounted in sleeve 32 extends radially therefrom and into slot' 3'3. The weath-erstrips 35, of L cross section, are rigid and equal in length to the height of the pane elements 29A and are firmly mounted by means of their integral collars 36 on the sleeves 32. Resilient insulating material 37 extends around the foot of the L of weatherstrips 35 and in sliding contact with the guide ledge 26D. Thus sleeves 32 and weatherstrips 35 are slidable as units longitudinally of pivot shafts 22 and pane elements 23A. Since outer surfaces of weather'strips 35, extending for a substantial distance on both sides of the axis of pivot shafts 22 and of sleeve 32, are in sliding surface contact with the inner surfaces 20F of guide ledge 23D, said surface 28F extending substantially longitud-inally of pane holding elements orsash 23A, relative rotation between Weatherstrip and sash is prevented, and rotation of sleeve 32 is effective to rotatethe pane elements 23A. In the illustrated position of Figure 5, weatherstrips'35 ex tend into the Weatherstrip grooves 33 formed in' side members NIB, 1 l, and extending from header 2 to sill i3 and facing into the window opening.

The window'operatesby rotating handle I8 clockwise of Figure 1, thus rotating gears H in the direction of the arrow of Fig-ure 3 and clockwise of Figure 4, sliding bars id upward, both bars [4 of the window moving together as previously explained. Upward movement of bars l4 causes rotation of gears 21 counterclockwise of Figure 3 and in the direction of the arrow of Figure 4. Segments 23 being fast to gears 25 will move with them. Pins 34 cannot rotate as they are fast to sleeve 32 which are fast to weatherstrips 35 which are engaged in grooves '38. Therefore pins Stand sleeves 32 with them will be cammed to the right of Figures 4 and, 5, disengaging weatherstrips 35 from grooves 38. Because the pivotal suspension of pane elements 28A is higher than the center of. gravity thereof, and also be'-' cause the axis of rotation of the pane elements is located inwardly of the window relative to the center of mass of the pane holding elements,

in all positions thereof, gravity will bias pane holding elements 23A towards a substantially vertical, closed position, so that they are at all times resisting the tilted position illustrated in Figure 2. Pins 34 being fixed against'rota'tion relative to pane elements 20A will thus resist rotation away from the vertical position of pane tion of handle [8 is first effective to progressively release pane holding elements 23A to the action of gravity to close the same, after which further rotation of segments 23 will cam pins 34 to the left of Figures 4 and 5 to return weatherstrips 35 into grooves 38' to simultaneously lock the window and seal it against the entry of the weather.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use. Asvarione possible embodimentsw might be made of the above invention, and as. various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is.v to be interpreted as illustrative and not in a limiting sense. 7 3
