WINDOW CONSTRUCTION.

i Application filed. March 13, 1922. Serial N0. 543,232.

To all whom t may concern i Be it known that gI, PAUL BECKER, a`

citizen of the United States, residing at p East Cleveland, in the county of Cuyahoga and State ,of Ohio,` have invented a certain new and useful Improvement in Window Constructions, of which the following is a full, clear, and exact description.

This invention y'relates to a window construction for buildings.

The principal yobject of the invention is to provide .a window `construction wherein both the upper and lower sashes may be readily removedy when desired for cleaning or'for any 4other purpose. Further the invention'aims to accomplish, the above result with what may be termed a weightless sash, that is toqsay, one which can be easily Araised and lowered, and which will stay at a lgiven position without thenecessity for the usual ropes and counterbalancing sash weights. .v

In the accompanying sheet of drawings, Fig. 1 is a perspective view of a window construction embodying my invention, the lower sashbeing removed and two molding pieces which respectivelyform portions of the guideways for the upper land lower sashes Vbeing shown by dotted linesout of their normal positions to illustrate the manner inwhich they may be swung to permit the removal of the upper and lower sashes; likewise in this view one ofthe weather strips for, the lower sash is shown by dotted, lines to illustrate its removability to permit the removal lof the lower sash; Fig. 2 is a. vertcal sectional view of ,the same showing by dotted lines` the upper enf . .one of the so-called anti-friction bearings;

Fig.7-.is adetailed sectional vieW illustrating the-manner in which theweather strippingis fitted into ythe window `frame so thatthe projecting portions' thereof will fit p -into the verticalV slotsv in-the'window sashes;

and Fig. 8 shows one of the two removable sectionsof the weather stripping removed from 'the frame.

Referring now to the drawings, 10 represents the window frame, and 11 and 12 the upper and lower sashes which are adapted to be moved up and down in verticalguideways at the sides of the frame 10.

As the present invent-ion contemplates the removability of the sashes from the frame 10, the usual sash weights and cords are eliminated, and in order that the sashes may be readily raised and lowered .and will nevertheless remain in a postion to which they may be moved, anti-friction rollers are provided at one or both sides of each sash, but preferably on one side only. Although ball bearings have been used by me very effectively, I prefer to employ cylindrical `bearings 13, and `to mount each of these bearings in a bifurcated endof a holder 14 1n the form of a metal stamping provided `with a shank which is fitted and held friction tight in openings provided in the vertical edge of the sash. Any number of these rollers may be provided along the side of the sash, butin this instance two are shown. These rollers are adapted to engage theopposing wall of the runwayof the frame 10 directly opposite the sash, and they are pref erably pressed yieldingly againstthe runway bywspring means which in this instance is provided at the opposite side of the sash and is here shown to consist of a Hat leaf spring 15, which is secured at one end to thesash and extends lengthwise of the sash. This leaf spring is bowed outwardly as best shown in Fig. 3, and it provides just enough friction to hold the sash in any postion to which it may be raised or lowered, but still it permits the sash to be moved quite readily.

To provide a construction which is substantially draft andA dust tight, weather stripping is provided for the sides and bottoni of the lower sash, and for the sides and top, of the upper sash. This weather stripping is ,in the forin-` of flat vmetal strips 16 the vertical ones of which fit into slots in the window4 frame and project` outwardly from the slots into companion slots 17 provided in the window sashes alongside the rollers` 13 and springs 15. F or the lower sash there is a weather strip which extends across the bottom of the frame, and two vertical strips which extend up along the sides from vthe windowframe, the vertical weather strips 16 along one side of the frame for both sashesare removable from thevslots which normally receive them. Should it be desired to remove the removable strip for the flower. sash, the latter is slid up to the top of the frame, whereupon the weather strip can be lifted out of place. Likewise, should it be desired to rem ove the removable strip forthe upper sash, the latter is moved4 downwardly in the frame to the bottom thereof, whereupon `the removable section of the weather stripping can be lifted out of place. The slots 17a of the frame which receive the removable vertical weather' strips 16 are of the same length as these strips so that the latter are not moved up or down when the sashes are raised or lowered.

To permit the sashes to be removed not onlyris itsessential that the weather strips lalong one side of the frame be removable,

but it is essential .also that the molding strips or portions thereof which constitute the front guide walls for the upper and lower sashes be readily removable, or movable to positions suchas to enable the upper and lower sashes to be swung inward and lifted bodily from the frame. This last mentioned feature is attained by, and consitutes an important part of the present invention.

In accordance with the presentlinvention the molding strip 18 which constitutes the front guideway for the lower sash at that side where the removable weather strips are arranged, is not permanently fastened in its normal position, but at its upper end is hinged or pivoted by a screw 19 or equivalent device, the pivotal axis being in a direction crosswise of the jamb so that this molding strip can be swung inward into the room. At its lower end adjacent the bottom of the frame, this stripfis held in place by asliding latch 20 .having a part which is adapted to projectacross the bottom of this molding strip, as indi-cated in Fig. 1, but when the latch is pulled back the molding stripv can be swung into the room.` Likewise a section 21 of the molding strip which forms the front or inner wall of the guideway for the upper sash at 'that side thereof where theremovable weather strips are arranged, ispivoted'to .the window frame at 22 so thatit also can be swung inward in the manner indicated by dotted lines in Figs. 1 and 2 provided the lower window is removed. It is not essential .that the .lower end ofthis molding section 21 befastened in place for normally the sashes hold it in normal position notwithstanding the fact that'it is pivotedtoswing in the manner just stated. Y

Ordinarily the molding strip 18 and the molding strip section 21 are vertical and function in the ordinary manner like fixed molding strips, as indicatedbyfull.v lines in F ig. 1. The sashes can now be moved up and downin the usual manner, and will stay where placed,.notwithstanding the fact that sash weights are not connected-'to them.

Should it be desired` toremove the lower sash to clean it, or for some other purpose,V this sash is elevated so thatitextends opposite the upper sash; then the removable weather stripping section 16 is slipped out of place.; then the molding strip18 is swung inwardly, i.e. away from. the frame.; and then the` sash may be lowered to its normal position and then swunginward at the.. side where the removable weather stripping, and movable moldingstrip are normally located,

.and then lifted out of place. To restore it,

dow frame and the removable weather stripy` section is slipped out of place; then'the sec tion 21 of the molding is swung inward then.

the sash is elevated somewhat so asto come opposite the opening .provided by the swinging. of the section 21 of the molding, and'V then is swung inward at the` side wherethe removable weather strip and swinging 1 molding strip are normally arranged, and then lifted bodily out `of place.

Thus it .will be seen 'that the Vobjects stated at the beginning of the specification are accomplishedin a very effective manner by the present invention.

Having described my invention, I claim: 1. In a window construction, a window frame 'having upper 4and'flower sashes slidable vertically in guideways formed by the frame, weather stripping carried by the frame land engaged bysaid sashes,'.sections of 4the weather`- stripping' engaged by up'- right portions 'ofthe sashesfon one side of` the frame being removable,l an'dfsa'id frame having on` the side upon which the Aremovable weather strippingis mounted molding strips with'movable` portions normally forming the innerwalls Vof vthe upright guideways stripping extend, one upright section normally engaged by the lower sash being removable from the frame when the lower sash is elevated to the top thereof, and one upright section of the weather stripping on the same side of the frame normally engaged by the upper sash being removable from the frame when the upper sash is lowered to the bottom of the frame, and said frame having molding strips constituting inner guide walls for the sashes,

portions of said molding strips on the side of the frame having the removable weather strips being movable to permit the removal of the sashes when the removable sections of the weather stripping are removed, said sashes being movable laterally in the frame sufliciently to permit the side freed from the weather stripping and molding strips to be swung inwardly.

3. In a window construction, a window frame having a pair of sashes movable up and down in vertical guideways of the frame, one in a plane at the rear `of the other, said frame having slots receiving weather stripping, and the sashes having slots into which portions of said weather stripping extend, one upright section normally engaged by the lower sash being removable from the Iframe when the lower sash is elevated to the top thereof, and one upright Section of the weather stripping on the same side of the frame normally engaged by the upper sash being removable from the frame when the upper sash is lowered to the bottom of the frame, and said frame having molding strips constituting inner guide walls for the sashes on the side of the frame having the removable weather stripping, portions of said strips being pivoted to swing inward so as to permit the removal of the sashes when the removable sections of the weather stripping are removed, said sashes being movable laterally in the frame sufficiently to permit the side freed lfrom the weather stripping and molding strips to be swung inwardly.

et. In a window construction, a window frame having a sash slidable therein, weather stripping for the sash comprising a section extending across the end of the frame and two upright sections extending vertically along the sides of the frame for substantialy the height of the sash, said weather stripping being in the form of flat strips located in slots of the window frame, and the sash having slots into which said strips normaly extend, one of the strips along one of the sides of the sash being readily removable from the slot of the frame when the sash is moved along the Iframe for substantially its height away from normal position, and said frame having a molding which normally retains the sash in the frame and constitutes part of the guideway therefor, a portion of the molding located opposite said removable section of the weather stripping being movable from normal position so asto permit the sash to be swung inward and lifted out of place when the removable section of the weather stripping is removed, said sash being yieldably supported in the frame whereby it is movable laterally to permit the side freed from the weather stripping and molding to be swung inwardly.

In testimony whereof, I hereunto aiiix my signature.

PAUL BECKER.
