Patented Oct. l, 1929 PATENT OFFICE WINDOW CONSTRUCTION Appnation meamay 5, 1927. seiial- N'o. 189,007.

This invention as indicated relates to a window construction. More'particularly it comprises a construction especially adapted for use with wooden windows which will at f. all times maintain the same in sliding engagement with the window frame irrespective of expansion or shrinkage of the sash or associated arts. It also includes 4a pair of guide mem ers preferably formed of metal 1o adapted to be associated respectively with the side of the window frame and the window sash and permitting adjustment or compensation between said parts so that they will not bind in the event of expansion of the wooden window frame or sash, and also to prevent shrinkage of thel wooden parts t cause such loose engagement that noisy vibration and leakage of air at the edges of the window will result.

It has heretofore been proposed to suspend windows resiliently so that motion of the sash in one direction would push against the guide member at one lateral edge and at the opposite ed e would exert tension upon the adjacent guide member. The present invention contemplates a similar arrangeemnt, but

also has in viewestablishing between one of the guide members and the supporting structure, an adjustment which will permit said vent bindin of the window, or any interference with s iding adjustment thereof.

' To theI accomplishment of the foregoing and related ends, said invention, then consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain structure embodying the invention, such disclosed means constituting, however, but several of various structural forms in which the principle of the invention may be used.

In said annexed drawing:

Fig. 1 is a side elevation showing a window construction embodying the principles of my invention; Fig. 2 is a sectional view taken along the line 2--2 shown in Fig. l;l

Fig. 3 isa similar view taken along the line 3 3 shown in Fig. 1; Fig. 4 is a fragmentary perspective view of the outer guide tube shown guide toassuine any necessary angle to pre-- in Fig. 1; Fig. 5 is a fragmentary view showing one construction of guide tube and resilient supporting member; Fig. 6 is a view similar to Fig 5 showing a modified form of supporting member; Fig. 7 is a top plan view 55 of a lateral edge of a window sash tted with a modified form of outer guide tube; and Fig.

8 is a transverse'sectional view of a modified form of inner guide member.

As is vclearly shown in Fig. .1, a wooden window sash 1 is provided in its lateral edge 2 with a channel 3 extending the entire length thereof. l/Vithin said'channel is inserted a slotted tubular member 4 of substantially the entire length of the window sash, said member having resilient tongues 5 formed by slitting the rearward portion of said member opposite its open or slotted side and adjacent each of its ends and bending resilient strips or tongues rearwardly therefrom. '10 The ends ofjsaid strips are secured by any suitable means such as screws 6 extendin through apertures 7adjacent said ends and into the base of the channel 'or groove formed in the lateral edge of the window sash.

The tubular member 4 is substantially cylindrical in form with a longitudinal slot 8 extending throughout its length on its outer side and is of a size to slidingly engage a guide member having a bead or tubular edge 1l formed on plate or base 12 adapted to be secured to the adjacent side of the window frame 13 by means of screws 14 or other fastening means. Thus there is provided a cylindrical guide member 11 within a cylindris cal sleeve 4, one of said members being firmly secured to the window frame and the other member being held in self-adjusting relation thereto within the groove at the lateral edge of the window sash. This construction, it will be noted, provides for free adjustment of the slotted cylinder 4 upon the cylindrical guide member 11. The window sash may expand or contract or be moved laterally or swung about a vertical axis without causing binding action on the guide members inasmuch as the guide member 4 isfiexibly supported. The degree of adjustment, between the window sash and window frame, it will be noted, isrelatively slight but the range of movement of the guide member 4 is fully adequate to take care of the expansion andcontraction which causes much difficulty in connection with the raisi`ng and lowering of windows at certain seasons of the year. This, as stated, is particularly true of windows of 4wooden construction, such las are used in dwellings, which often swell to such an extent that it is impossible to move them or which become so loose that they will rattle and cause much annoyance. I

lfVhile the strips or tongues 4 are adequate to position the outer tubular member, additional or substitute means may also be employed. Thus there is shown in Fig. 1, slotted plates 15, 16 attached-to the ends of the outer tube and bearing against the ends of the lateral member of the sash. The slotted plate is soldered, welded, or secured in any other suitable manner to the top edge of the outer tube and because of the wide slot 17 and the thin gauge ofthe material of the plate, the elasticitv of the slotted tubular member is not materially affected insofar as relates to its engagement with the inner tubular member. .Said slotted plates form air stops to prevent air currents in the guide channels.

'lhe outer tube may be formed with integral tongues as shown in Fig. 5 or may have separate strips 21 spot welded thereto, as is shown in Fig. 6, or secured in any other suitable manner to the tubular member 22 adjacent the respective ends. j

As is shown in Fig. 7, the outer tube 23 may7 be formed lof a strip of sheet met-al folded reversely at either side upon itself to provide an inner cylindrical portion and overlying side portions 24,. A pair of plates 25, 26 may be secured to the respective side portions at each end of the tubular member to maintain it in engagement with-the lateral grooved portion 27 of the sash.

A modified form of inner tubular member may also be employed, that shown in Fig. 8 being formed of a single strip of metal having a flat base 31 with side portions 32 bent toward each other and having marginal portions 33 of arcuate cross-section. The securing screw 34 or other fastening element is provided with a beveled head 35 adapted to contact with the inclined inner faces of the side portions and thus serve as an adjusting element for 'spreading apart or relieving the spreading action upon the arcuate marginal portions. In this manner the inner guide member may be given any desired degree of frictional engagement with the outer guide member.

In addition to thus compensating for eX- pansion and contraction, the apparatus may e adjusted to provide a degree of frictional engagement between the guide members which ma be adequate to maintain the window in a justed position without the use of the usual cords, pulleys and weights. Should the window be of somewhat more than usualof cords, pulleys and weights. This may be more readily accomplished by placing thev inner cylindrical guide member upon the window sash and placing the outer flexibly held slotted cylindrical member within a channelway ina Window frame. `The cords in such event would be concealed within the tubular guide and a very much improved appearance would be given to the window over the type of construction now in general use.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the structure herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed. f

I therefore particularly point out and distinctly claim as my invention:
