8 Claims. (Cl. 189-75) This invention relates to a window frame structure and particularly to improvements in the jamb assembly thereof.

The invention is embodied in a window assembly of the storm sash screen type wherein three guide channels are provided adapted to carry three slidable sash. Two of these sash may be'storm sash and thethird sash a screen sash. The invention is here shownas embodied in such an assembly formed of metal such as aluminum.

An object is to provide such a window structure wherein the window sash may be readily removed from the inside of a building for washing and easily and quickly replaced in position.

A meritorious feature is the provision of a jamb assembly so constructed that the removal and replacement of sash is facilitated by partially disassembling the jamb structure and this can be readily and quickly accomplished.'

Another meritorious feature is the provision of a jamb assembly of the character specified wherein the lower portion of certain guide channel members may be detached from the remainder of the jamb assembly so as to facilitate the removal of sash therefrom.

A further meritorious feature is the provision of a jamb assembly of the character described wherein two of the guide channels are embodied in parts which are so associated with the remainder of the assembly as to dene with such remainder three guide channels but the parts which make up the two guide channels may be removed from the remainder of the assembly so far as the lower portion of the assembly is concerned while remaining a part thereof through the upper portion of the assembly.

Another object is the provision of a jamb assembly in a window structure of the character specified wherein one of the guide channel walls is bent at the upper corner of the lower portion of such guide channel out of the plane of the channel and into the plane of the adjacent channel forming a yielding part which is adapted to engage underneath a sash when elevated thereabove to support the same.-

Other objects, advantages and meritorious features will appear from the following description, claims and accompanying drawings, wherein:

Fig. 8 is a horizontal sectional view taken on the line 8-8 of Fig. 1;

Fig. 9. is a horizontal sectional view taken on the same line as Fig. 8 but showing the lower portions of two of the guide channels withdrawn from the remaining portion of the assembly;

Fig. l0 is a horizontal sectional view taken on the line 10-10 of Fig. l.

The window structure is shown as mounted within a window opening on the outside thereof. Such window opening is provided in a building that is ordinarily constructedwith a stationary jamb element 20 which is rabbeted asat 22 providing a shoulder upon which the assembly may be secured by means of screws, nails or the like 24, as shown particularly in Figs. 3, 4, 6 and 7. The window opening of course is provided with a header and a sill shown in dotted outline in Fig. 1.

My window structure comprisesa pair of opposedy of sheet metal shaped so as to delne three header wells within which the upper rails of the three sash carried by the window structure may be received. The two jamb assemblies -are connected together at the bottom by a sill assembly 28, shown more particularly in Fig.`2 which exhibits an upstanding portion 30 terminating in a ange 32 adapted to seatupon the stationary window sill. The portion30 is provided with an upstanding ledge 34 on the inside of the window opening. The invention claimed resides particularly in the construction of the jamb assemblies. The two jamb assemblies are similar.

Each jamb assembly comprises a base channel member 36 which is directly secured by the screws 24 to the stationary jamb on the window. This base channel member extends through the length of the jamb assembly. Connected with and seating kupon the base channel memberk The screws 24 extend through the leg 40 of the Z-shaped member and secure the same within the base channel, as shown particularly in Figs. 3 and 4. The other leg of the Z-shaped member which is indicated as 42 and which projects in the opposite direction from the leg 40 constitutes a side wall of one of the three guide channels. This leg 42 may be folded over upon itself as at 43 as shown in Fig. 4.

There is a guide channel sub-assembly which is made up of two guide channel members. One guide channel member is indicated by the numeral 44. It is twice the width of a guide channel runway. It is seated upon the base of the Z-shaped member 38. It has one side wall 46 which is spaced such a distance from the side wall 42 of the Z -shaped member that it defines therewith one of the three guide channels. The other guide channel member which goes to make up the guide channel subassembly is indicated by the numeral 48. It is seated within the guide channel 44 as shown particularly in Figs. 3 and 4. It has a guide channel wall 50 which is so spaced from the guide channel wall 46 that it defines therewith a guide channel. It has another guide channel wall 52 which with the wall 50 defines a guide channel.

The guide channel wall 52 is bent over upon itself as at These jamb assemblies are secured to-A frictionally received within the channel of the leg 40 of the Z-shaped member, as shown particularly in Figs. 3, 4, 6, 8, 9 and 10. The engagement of the lip portion of the folded over wall 54 within the channel of the leg 40 of the Z-'shaped member 38 is what holds the sub-assembly upon the Z-shaped member.

Throughout Ythe upper portion of the jamb assembly the screws 24 extend also through the leg 54 and serve to retain the parts together. Throughout the lower portions of the assembly the screws do not extend through the lip ofthe wall '54 and such lower portions of the sub-assembly are therefore readily removable, as shown in Fig. 7.

It will be seen that the sub-assembly which is made up of the guide channel 44 and the guide channel '48 is divided into upper and lower portions, as shown particularly'in Figs. 6 and 7. The upper portions have a vertical dimension greater than the vertical dimension of the sash 'that are slidably mounted within the window assembly. The sash may therefore be elevated into the upper portion of the sub-assembly entirely clear of the lower portion and permitting removal, as shown in Fig. 7 by withdrawal of the lip 54 from the channel of the Z-shaped member.

In the window assembly the upper storm sash is indicated as U, the lower storm sash as L, and the screen as S. These sash structures are shown in position in Figs. l and 2 with the screen and one of the sash lowered in Fig. 2. In Fig. all three sash are shown as elevated above the lower guide channel assembly and into the upper guide channel assembly. When it is desired to remove the sash from the assembly they are raised into the upper portions, as shown in Fig. 5. The lower portions of the guide channels which make up the sub-assembly may then be withdrawn, as shown in Fig. 7 because the lip S4 in the lower portion of the sub-assembly is of less width than the lip in the upper portion and is not pierced by the screws 24.

The side wall 46 of the channel 44 has its upper cornerbent out of the plane of the channel, as shown at 58, in Figs. 5, 6 and 7 so that such yielding corner bend is disposed within the outer guide channel and therefore will serve to hold the sash U in the elevated position when the sash is raised thereabove, as shown in Fig. 5. Also as .shown in Fig. 5, the side walls of the channels preferably present a wave-like contour as shown by reference character 60 so that friction is exerted upon the sash sliding through the channels sufficient to maintain them in positions of elevated adjustment.

It is apparent, therefore, that in a window frame as herein described not only will the sash be maintained at adjusted elevated positions but the sash may be relatively easily removed from the frame. Such sash may be raised into -the upper portion of the window frame. The subassembly of each janib assembly may then be withdrawn as shown in Fig. 7. Each sub-assembly may be withdrawn inwardly. Upon withdrawal of this sub-assembly a sash may be lowered from the upper half of the frame into the'lower half. Such sash may then be moved laterally from the frame. Each of the sash may be thus removed.

For replacement the sash may be inserted into the lower 'half of the frame and elevated. Upon elevation of the sash the opposed assemblies may be reinserted and the window is ready for use. It does not require any tools or removal of screws or the like to effect the removal and replacement of the sash.
