Description
June 24, 1958 E. D. BISHOP WINDOW CONSTRUCTION Filed July 29. 1955 l 2,839,794 Patented June 24, 1958 j 2,839,794 .jf v VvviNnow, CoNsr-'RCTION f Everett D; Bishop, Kansas City, Kans. `application Jury 2,9, 195s, serial No. 525,108 z claims. V(ci. zii-52.2)
This .invention relates Vto 'new' and useful improvements window constructionin which -a window sash, or sashes, are mounted slidably 'in a frame. In windows of this type, the sashes are commonly held at any adjusted elevation by a system of sash cords, pulleys, and sash weights. v
The principalobject of thepresent inventionistheprovision of a window kof the Vgeneral class :described wherein the sash cords, pulleys and weights -are'eliminated Another object yis the provision -of .a window of the class described wherein the sashes are held releasably at United Sit-.MCS
formedtospresent longitudinal grooves 22 therein. At the opposite-side of the frame, adjacent the inner face of jamb 8, another pair of tracks 24 and 26 are mounted between stops 12 and 14, and cooperate respectively with tracks 18 and 20, having grooves 22 formed longitudinally in the operative faces thereof. Tracks 24 and 26, however, are movable transversely toward and from the iixed tracks. Each of the'movable tracks is supported by a plurality of screws 28 disposed at spaced intervals along the length thereof. Each of said screwshas an enlarged at head 30 embedded in alsocket 32 formed in the gr-ooved face of the track. Said screw then extends l through the' track, and is threaded into jamb 8. VA coil any "elevation by a'frictional device, said frictional deviclebeingryieldable whereby to compensate for Iday-today expansion and Vcontraction ofthe frame andsashes due to temperaturean'd humidity changes, and adjustable in tension whereby to compensate for sashes Vofdifterlent weights, and to compensate for wear.
A further object is the provision of a window of the class described wherein the sashes are easily removable from the frame for convenience of cleaning and repair, but which are nevertheless normally locked against unauthorized removal, as by burglars.
Other objects are simplicity and economy of construction, ease and convenience of use, and adaptability of the operating principles for use in connection with other devices employing slides.
to a position permitting the removal thereof from the frame.
Like reference numerals apply to similar parts throughout the several views, and the numeral 2 applies to a window frame having the usual lower sill 4 and top rail 6.
`The side rails or jambs 8 and 10 `are attached at their lower ends to sill 4 and at their upper ends to top rail 6, and are parallel. An inner stop board 12 extends around the top and sides of the frame, extending inwardly therefrom. An outer stop boa-rd 14 extends around the top and sides of the frame at the outer face thereof, projecting inwardly from said frame. Avdecorative facing, or molding 16 is applied to the outer face of stop 14, and it is to be understood that a similar strip or strips, not shown, could be applied to innerstop 12.
Mounted against the inner face of frame jamb '10, between stops 12 and 14, are a pair of slide tracks 18 and 20.` Said tracks are offset from each other transversely to the plane of the window, extend the full height of the frame, and are ixedly secured in said frame in any suitable manner. The operative face `of each track is spring 34 is disposed about the screw between the jamb and the track, said` spring seating yin a socket 36 `formed therefor in the jamb. -A smaller, weaker spring 38 is disposed between ;the screw head 30`and the bottom of socket 32 of the track, for a purpose .described below.
An upper sash 40 is carried slidably between tracks 24 and 1'8, the side rails 42 `of said sash having ribs 44 formed therein engaging the grooves 22 of said tracks. A lower sash 46 is carried slidably between tracks 26 and 20, the side rails 48 thereof also having ribs 44 for engaging the tracks. Each of the sashes carries the usual glass pane 50.
It is apparent that springs 34 Apress tracks 24 and 26 frictionally against the sashes, the opposite edges of the sashes engaging ixedy tracks 1'8 :aand 20. As long as the frictional load on-'each sash is proper, it is evident .that said sash wil-1 .be prevented from -moving lby its own weight, and will be retained at any elevation to which it is manually moved. At the same time, a slight amount of manual pressure on the sash will overcome the Itrack friction, and the sash may be moved easily to any positiondesired. Thus the usual sash cords, pulleys and weights are completely dispensed with, with consequent apparent advantages of economy, simplicity and spacesaving. Other advantages are that this structure renders theconnection virtually air and dust-tight, and rattlefree.
Adjustment of the frictional load on the sash may be obtained by turning screws 28 witha screwdriver. Each screw carries a stronger spring 34 urging the track against the sash, and a weaker spring 38 urging the track away from the sash, so that the total resultant force urging the track against the sash is equal .to the compressive loady of springs 34 minus the compressive loads of springs 38. The two springs are so proportioned that spring 38 can never completely overcome spring 34 or move the track away from the sash.
It will be apparent from Fig. 3 that either of the sashes may be removed from the frame by first moving the sash bodily to the left, forcing the movable track outwardly against springs 34, until the ribs 44 vat the left edge of the sash clear the grooves 22 of the fixed track. The left edge of the sash may then be tilted out of the frame, and the sash lifted clear of the frame. The sash may be reinserted by reversing the above process.
However, it will be noted that for most positions of each sash it cannot be moved to the left, since it overvlies the heads of screws 34, and will butt against said will not interfere with the sash-retaining properties there- When the sash is m-oved to one certain position of elevation, sockets 52 formed in the side rail thereof adjacent the movable- `rail will be brought into'ialignment with y Y `vertical movement vby any well-known securing means,
not shown, the sashes cannot be forced horizontally to the side and removed, as'by a burglar. -Y
Each of the movable tracks 24 and 26 is provided with four screws 28, spaced as shown in Fig. k1. -It is desirable that the space between any two alternate screws, as between the rst andthird or second and fourth screws, be less than lthe linear length of the sash in engagement with the slide. This insures that the sash will always overlie at least two screws, and sometimes three, and'thereby assists in preventing tilting or canting of the sash in the frame. It is also desirable that-the spacing between any two successive pairs of screws be unequal as Yshown.
This prevents theY occurrence of more than one position at which the sash may be removed,.and hence reduces the probability that the sash might be movedto a removal position purely by chance.
Although I have shown and described a specificV embodiment of my invention, it will be apparent that many minor changes of structure and operation could be made without departing from the spirit of the invention as defined by the scope of the appended claims.
What I claim as new and desire to protect by.. Letters Patent is:
l. A window structure including a frame having a pair of parallel jambs, a rst slide track fixed to the rst of said jambs, a second slide track, a plurality of screws attaching said second track to thevsecond of saidljambs, and a sash having its opposite edges respectively in slidv enlarged heads countersunk in the face of the track engaged by said sash, and compression springs disposed between said second track and second jamb, said sash andV tracks having mating ribs and,r grooves whereby said sash must be moved transversely to saidtracks in its own plane to disengage it from said tracks, the' clearance between the heads of said screwsY and theadjacent edge of said sash being less than the transverse movement required to free the sash, said sash having a plurality of sockets formed in the edge thereof adjacent said track and adapted to be brought into registering relation with said screws when said sash is moved to one position, whereby said sash may be removed.
2. A structure as recited in claim 1 wherein said screws are spaced along said track at'intervals such that the space between any alternate pair thereof is less than the linear engagement of said sash with said track, and the screw intervening between said pair of screws is spaced unequally from the screws of the pair. f
