2 Claims.

This invention relates to window structures of the type in which window sashes are slidable in window frames and are frictionally held in adjusted position without the use of pulleys, sash cords or, counterbalancing weights.

It is a` primary object of the invention to provide improved and simplied guide channels and slider element structuresA for the sashes which can be readily applied in standard window frames without changes therein, so that our invention may be readily applied to existing as well as newly installed windows.

A further object of the invention is to provide improved structure and arrangement for more readily detaching the window sashes from their guide structures so that the sashes may be bodily removed from the frames for purposes of decoration or repair, or for washing. I

Another important object is to provide simple guide and slider elements for supporting and aligning the sashes and which will cooperate to function efliciently to seal the window against the weather without need of special weather stripping or other special sealing means.

The various features of our invention are incorporated in the structure shown on the drawings, in which drawings:

Figure l is a front elevation of a Window comprising upper and lower sashes;

Figure' 2 is an enlarged cross section on plan II-II of Figure 1;

Figure 3 is an enlarged section on plane III-III of Figure 1;

Figure 4 is an enlarged section on plane IV-IV of Figure 1;

Figure 5 is a section like Figure 4 showing the lower sash raised and the upper sash shifted down in the frame;

Figure 6 is a section like Figure 5 showing the lower sash detached from its guide elements and ready to be bodily removed from the frame;

Figure 7 is a section on plane VII--VII of Figure 4;

Figure 8 is a section on plane VIII--VIII of Figure 5;

Figure 9 is a section on plane IX-IX of Figure 2; and

Figure 10 is a section on plane X-X of Figure 9.

Referring to Figures 1, 2 and 3, the window frame shown is of the usual standard construction comprising the sill ID, the upper rail II, and the sides or uprights I2. Along the inner edges of the sides I2 are detachably secured the molding stops I3 and along the outer edges of the sides are the usual blind stops I4, a top stop strip I5 secured to the upper rail II registering with the stops I3. v

At each side of the window frame are a pair of inner and outer guide channel bars I6 and I'I which extend between the sill and top of the frame and are confined transversely between the inner and outer stops I3 and I4. 'Ihe inner channels I6 form guideways for the inner sash I and the outer channels I form guideways for outersash O. As best shown on Figure 10, each guide channel bar is of rectangular U-shaped cross section comprising the back wall I8, the side walls I9 and 2U and the retaining flanges 2| and 22 extending inwardly from the side walls into parallelism with the back wall. l

Referring particularly to Figures 7, 9 and 10, in each of the channels I6 is a slider element S of a length equal substantially to the height Vof the inner sash I. Each guide element comprises a comparatively wide strip 23 and a narrower strip 24 with one or more springs 25 between the strips tending to urge them respectively into friction engagement with the side walls I9 and 20 of the guide channel, the strips being of a depth for friction engagement with the back Wall of the channel and the retaining flanges 2l and 22 respectively. As shown on Figure 9 the springs 25 may be leaf springs with their deflected ends 25 anchored in slits 26 provided in either of the strips 23 or 24. Dowel pins 21 extending from the strip 23 extend into passages 28 in the strip 24 to hold the strips in alignment.

As best shown on Figures 2, 5 and 7, the strip 23 of each slider element S has embedded therein near its upper end a nut member 29 for receiving a screw 30 extending through a passage- Way 3I at the upper end of the corresponding side of the inner sash I so that when the screws are applied, the inner sash willV be secured to the slide elements in the opposite channels I6. When the inner sash is raised or lowered the slider'elements S to which it is secured will move in the guide channels IB and the frictional engagement of the spring-pressed slider strips 23 and 24 with the Walls of the guide channels will hold the sash in any adjusted position.

In order to hold the Asash in longitudinal alignment with the slider elements S, the slider elements are provided with guide rails or tongues 32. This tongue may .be 'a separate piece secured to the slider element strip 23, or may be integral therewith as shown on Figure 10. For receiving these guide'rails or tongues 32, the

-sash sides have the longitudinal extending channels 33 cut therein as `best shown on Figure 2. The tongues 32 terminate a distance above the lower ends of the slider element strips 23, and in the lower ends of the channels 33 stop pieces 34 are secured for abutting at their upper ends with the lower ends of the guide rails 32 when the sash is secured to the slider elements by the screws 30, this abutting engagement assisting the screws in holding the sash and slider elements against relative longitudinal displacement. In order to assist the screws in holding the sash and the slider strips together laterally, the labutting ends of the guide rails and the stop pieces 34 may be undercut or beveled as indicated at 35.

Describing now the procedure for bodily removing the inner sash from the window frame, it will be noted on Figure 2 that the Width of the sash is sligthly less than the distance between the front stop strips I3. On Figure 4 and in full lines on Figure 7 the inner sash I is shown in its lower or closed position with the screws 38 applied to secure the sash to the slider elements S. To release the sash for bodily removal from the frame, the screws 30 are withdrawn and the sash is raised as shown on Figures 5, 8 and by the dotted lines on Figure 7. Due to the abutting engagement of the stop pieces 34 on the sash with the ends of the guide tongues or rails 32 on the slider elements, the slidel` elements will be shifted up in their guide channels I6 with the sash. The sash is now shifted down to its .normal position along the guide tongues or rails 32, the slider elements being retained at the upper ends of the channels I6 by their frictional engagement with the channels. The sash channels 33 being now free of the tongues 32, the sash may be bodily removed from the window frame. To reapply the sash, it is set on the sill I in alignment with the'channels I6 and then shifted upwardly for reception of the tongues 32 in the sash channels 33 and the screws 30 are reapplied and the sash together with the slider elements is shifted down to its normal closed position. It is evident that, in order to remove the sash, it could first be raised to its upper position and the screws 30 then removed, and the sash then shifted down forbodily removal from the frame.

The outer sash O is mounted in the guide `channels II by slider elements S in the same manner as the inner sash. To bodily remove the outer sash, the usual procedure would be to rst raise the inner sash and then lower the outer sash and remove the screws 30 from the outer sash. The outer sash, after raising thereof together with the slider elements would then be shifted down along the slider element guide tongues 32 to withdraw the sash from the tongues so that the sash could then be bodily removed from the frame. To reapply the outer sash it is set on the sill in alignment with guide channels I'I and then shifted upwardly for reception of the tongues 32 by the sash channels 33, and then after a slight downward shift of the inner sash the screws 30 could be reapplied to the upper sash.

Another way of reapplying the sashes would be as follows. For reapplying the inner sash, the sash could be set on the window frame sill and the slider elements S shifted downwardly with their tongues 32 in the sash channels 33, and the screws 30 then applied. 'For reapplying the outer sash, it could be set on the sill and then, after suilicient downward shift of the inner sash for access to the slider elements for the outer sash, these slider elements could be shifted down for re-engagement with the outer sash channels 33 and application of the screws 3U. Thus for bodily removal of a sash from the frame, all that is necessary is to withdraw the screws 38 and vertically shift the sash for disengagement from its slider elements, and for reapplication of the sash all that is necessary is to set it into alignment with the guide channels and shift it vertically into reassociation with its slider elements, and then reapplication of the securing elements, such as the screws shown.

When the stop strips I3 are applied to the window frame, the channels I6 and I'I will be held with their inner side walls in intimate engagement and their outer side walls in intimate engagement respectively with the stop strips I3 and the strips I4, so that weather-tight joints result. The springs 25 will hold the strips 23 and 24 of the slider elements against the side walls of the guide channels, and the beveled abutment engagement 35 between the strips 23 and the sash stop pieces 34, and the screws 3|, will hold the tongues or rails 32 intimately in the sash channels 33, and the retainer flanges 2| of the guide channels will be intimately en gaged by the slider element strips 23 and the side walls of the sash adjacent to the channels 33, so that tight weather joints are provided. The retainer flanges 22 of the guide channels will be intimately engaged by the sash sides adjacent to the channels 33. With our improved arrangement it is therefore unnecessary to provide special weather stripping or weather sealing elements.

The slider strips are free at all times to be pressed by the springs 25 against the guide channel side Walls 20 to maintain the necessary friction between the slider elements and the guide channels for holding the sashes in raised positions.

As shown on the drawings, Window sashes and the slider elements S are shown as constructed of wood. It is evident, however, that these structures may be of metal. Where the sash is of wood, metal plates 36 are preferably provided to form seats for the screw heads and to prevent cutting or marring of the wood.

We have shown practical and efficient embodiment of the various features of our invention, but we do not desire to be limited to the exact construction, arrangement and operation shown and described as changes and modifications may be made which will still come within the scope of the invention and the appended claims.

We claim as follows:

1. In a window frame having outer and inner stops at each side, a pair of sheet metal guide channels at each side of the frame extending from the top to the bottom thereof and held laterally by the frame inner and outer stops, said channels along their outer edges having each inwardly directed retaining anges, a slider element in each channel confined therein by the retaining iianges of the channel and having sliding movement in the channel longitudinally thereof, friction means for each slider element tending to hold it in any position in the respective channel, an inner window sash between opposed channels and having tongue and groove connection with the slider elements in said channels, an outer sash between the opposed other channels and having tongue and groove connection with the slider elements in said channels and having detachable means for securing it to said slider elements, the frictional engagement of said slider elements in the channels being sufcient to hold the respective sash in any position thereof in the frame whereby, after movementl of a sash with the slider elements therefor to on-e end of said frame and subsequent release of the securing means, the slider elements will remain at such end of the frame and the sash may be moved toward the other end of the frame away from the slider elements for bodily removal of the sash from the frame.

2. In a window frame having a channel at each side thereof, a slider element in each channel for sliding longitudinally therein, a window sash having tongue and groove connections at its sides with said slider elements, securing means for securing said sash to said slider elements for movement of said elements with said sash when said sash is raised or lowered, means eiecting suicient friction between said slider elements and said channels for holding said sash in any adjusted position in said frame, cooperating bevelled abutments on said sash and said slider elements functioning independently of said securing means to hold said sash and slider elements laterally together and to cause said slider elements to move with said sash when said sash is raised but permitting downward movement of said sash relative to said slider elements, said securing means being releasable so that, after movement of said sash With said slider elements to the upper end of said frame, said slider elements will be frictionally held at such end and said sash may be moved in downward direction for longitudinal disengagement thereof from said slider elements and bodily removal from the frame.
