NOV. 7, J. KLEIN WINDOW CONSTRUCTION Filed Feb 26, 1931 2 Sheets-Sheet l ATTORNEY Patented Nov. 7, 1933 L UNITED STATES PATENT OFFICE WINDOW CONSTRUCTION August J. Klein, Dubuque, Iowa Application February 26, 1931. Serial No. 518,419

2 Claims. (01. 20 -1'2 The invention relates to improvements in window constructions, and has for its primary object the provision of an improved construction of this character so constructed and arranged as to permit of the ready removal of the window sashes when desired.

Another object of the invention is the provision of an improved construction of the character indicated so constructed and arranged as to prevent rattling of the window while in use.

Another object of the invention is the provision of a construction of the character indicated so constructed and arranged as to be practically water and wind tight.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by refer ence to the accompanying drawings forming a part of this specification, and in which Fig. l is a partial interior face view of a window construction embodying the invention;

Fig. 2 a transverse section of the same taken through the sill of the window;

Fig. 3 a transverse section taken through the head jamb of the window;

Fig. i an enlarged horizontal section taken throughone side of the window frame; and

Fig. 5 asimilar section taken through the opposite side thereof.

The embodiment of the invention illustrated in the drawings comprises a suitable window frame constructed and arranged to be inserted in the wall of a building in the usual way and having a permanent jamb 10 at one side provided with the usual moldings and

strips

11, 12 and 13, providing the usual pair of adjacent guide grooves for the window sashes 14, this part of the construction being the ordinary, normal window frame construction.

At its opposite side the window frame is provided with a vertical side or anchoring jamb 15 secured as shown between vertical frame strips 16 and 1'7. A laterally slidable jamb 2 is arranged to slide laterally between the vertical frame strips 16 and 17, said jamb 2 being provided with moldings and strips 18 and 19, providing as shown the usual guide grooves for the window sashes 14. The slidable jamb 2 is yieldingly pressed into sliding engagement with the sashes 14 by means of three compression springs 1, each compression spring fitting over a corresponding positioning block 7 and fitting into a corresponding positioning socket 9, whereby each spring is properly held in place to perform its function of yieldingly and evenly pressing the jamb 2 into slidable engagement with the window sashes.

Guide strips 5 are arranged as shown on each jamb 10 and 2 substantially at the center of each sash groove, and each sash is provided on each side with a corresponding guide groove as shown to fit the corresponding guide strip. Each sash groove is provided at each end with a bearing block 4 adapted and arranged to ride upon the corresponding strip 5 and thereby confining the pressure to the four corners of each sash to pre-' vent binding when raising or lowering the same. For this purpose, each of the blocks 4 is preferably made of fiber composition.

A guide block 6 is arranged on the window sill in position to contact with the outer edge of the bottom of the slidable jamb 2 when it emerges from behind the strip 16, so that when the sashes are removed from the window the slidable jamb 2 will be held in place. A guide strip 6 is also provided on the head jamb of the window frame, as best shown in Fig. 3, there being a corresponding groove formed in the top of the outer sash to act as a weather strip and guide when the outer sash is in its uppermost position.

A suitable chamier or notch 8 is provided at the lower inner edge of the strip 1'7, as indicated by the dotted lines in Fig. 4, to permit of the draining of any water entering the pocket in which the slidable jamb slides.

By this arrangement, it will be noted that the sashes can be removed without interfering with or removing the parting strip or any of the guide strips or moldings of the window frame by bringing pressure to bear upon the top and bottom of the slidable jamb, thereby springingsaid slidable jamb back far enough to permit of the ready removal of the sashes. As will be noted, the slidable jamb is at one side only so that the other jamb is the same as in any standard win dow frame construction. The construction thus provided will not shake or rattle in use, and when the window sashes are closed, is practically air and wind tight. As indicated, no sash cords or sash weightsare required for said sashes.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details disclosed, but desire to avail myself of such variations and modifications as fall within the scope of the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A window construction comprising a frame having a jamb at one side provided with two adjacent guide grooves for window sashes; a laterally slidable jamb at the other side also provided with two adjacent guide grooves for said sashes; a plurality of positioning blocks on the vertical medial line of the outer side of said slidable jamb; compression springs engaging such positioning blocks and the adjacent frame sides, there being sockets in said frame sides registering with said blocks to receive the ends of said springs; a guide strip on each jamb substantially at the center of each of said guide grooves, there being corresponding guide grooves in said sashes to receive said strips; bearing blocks at each end of the guide grooves in said groove for a window sash; a laterally slidable spring-held jamb at the other side also provided with a guide groove for said sash; a guide strip on each jamb substantially at the center of each of said guide grooves, there being corresponding guide grooves in said sashes to receive said strips; and bearing blocks at each end of the guide grooves in said sashes to contact with said strips.
