6 Claims. (CL 2055) The object of my invention is to provide an auxiliary sash for a window frame having certain characteristics for forming a ventilator and having novel supporting means for the auxiliary sash when being installed or when in partially open position.

Still a further object is to provide an auxiliary sash having either a glass or screen covering, the frame and supports therefor being of simple, durable and inexpensive construction.

Another object is to provide an auxiliary s'ash arranged for easy installation and which permits perfectly controlled ventilation besides involving features of convenience for installing the auxiliary sash in a window frame and also for removing the auxiliary sash for swinging it outwardly for cleaning windows oi.' the window frame.

A further object is to provide an auxiliary sash which may be either installed from a ladder outside of a building or pushed out through the window opening and installed with the installer located on the inside of the building.

More particularly, it is my object to provide coacting means at the top of an auxiliary sash for registry with a window frame, with an additional support for the auxiliary sash while being moved to position to register at its coacting upper edge.

With these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawing; in which:

Figure 1 is anoutside elevation of a window frame, an auxiliary sash therein and a support for the auxiliary sash embodying my invention.

Figure 2 is an enlarged sectional view on the line 2-2 of Figure 1.

Figure 3 is another sectional view on the line 3-3 of Figure 1 showing the parts in a different position.

Figure 4 is a sectional view on the line 4-4 of Figure 2; and

Figure 5 is a perspective view of the auxiliary sash supporting means.

AOn the accompanying drawing, I have used the reference character A to indicate generally a window frame and B, a storm sash. 'I'he window frame A has a sill 10, side jambs 12 and a head 'jamb 14. Side casings 16 and a head casing 18 are provided for the window frame A in the ordinary manner.

'Ihe storm sash B is of the ordinary kind adapted to abut against side and upper

blind stops

20 and 22 with its outer face flush with the

casings

16 and 18. The upper edge of the storm sash B is retained in position by means of a bead 24 thereon coacting with a groove 26 in the lower edge of the head casing 18. The lower end of the storm sash B may be held in position by any`r suitable means. y By way of illustration, I show hooks 28 coacting with pins 30.

The bead 24 coacting with the groove 26 and the hooks -28 (one on each side of the sash B) 6 are al1 that is required to hold the sashB in position. No water can run in over the top of the sash, as in the usual construction, in employing the bead 24.

One of the objections to such construction is in installing or removing the storm sash. To facilitate this operation, I provide hooks 32 in the side casings 16 adjacent their upper ends.

The hooks 32 have upwardly extending terminal ends 34. The hooks 32 may be screwed into the casing as illustrated or provided with base flanges forattaching by means of screws, or any suitable means for supporting them may be provided.

Secured to the upper corners of the sash B are lugs 36. These may be screwed in position by screws 38. The lugs 36 project out over the. hooks 32 and have depressions or notches 40 for alignment purposes. The notches 40 serve to center the sash B relative to the hooks 32 so that it is in alignment with the opening it is to t. The notches also prevent slipping of the lugs 36 olf the hooks 32. The upturned ends 34 of the hooks 32 limit outward movement of the lugs 90 relative to the hooks.

When installing the storm sash B, the sash may be lifted for elevating the lugs 36 over the ends 34 of the hooks 32, as indicated by the arrow a in Figure 3 and then the lugsmay engage the hooks as shown in the full line position. The sash may be installed from a ladder outside the building or may be projected outwardly through the window frame opening by an installer on the inside of the building.

With the sash supported on the hooks 32, the m0 installer may now get a second and more convenient hold on the sashbefore finally pushing it into position, as indicated by the arrow b and the dotted line position in Figure 3. It will be 105 noted that the sash B is now in position for coaction of the bead 24 with the groove 26 upon lifting of the sash. The sash is preferably kprovided with'one or more hand hold notches 42 to facilitate the lifting operation to the position 'uil shown in Figure 2.

The hooks 28 may then be manipulated for retaining the sash B in installed position.

The

hardware parts

32 and 36 provide a very convenient means for a half-way station or breathing spell during the installation or removal of the storm sash. It is evident that the hardware can be used equally as effective on screens and therefore in some of my claims I have referred to an auxiliary sash rather than a storm sash. It will be obvious that an auxiliary sash can have either a glass covering or a screen cov-- ering. Y Y

Having the

hardware

32 and 36, the sash B lcan. be swung and slid loutwardly to the dotted-line position shown in Figure 2 for cleaning the inner and outer sashes 44 and 46 which slide vertically in the window frame A. This desirable adjustment is entirely lacking without such hardware. A further use for the supporting hooks 32 is in allowing the storm sash to assume a Ventilating position, but this is not so practical when the wind is blowing and causes a direct draft into the room. I have illustrated a more practical method for ventilation comprising a ventilator section 48 which normally assumes a. closed position in an opening 50 of the sash vB. I

The top and side edges of the ventilator section 48 are rabbeted to provide flanges 52 and 54 for lapping over the inner edge of the sash B. The lower edge is rabbeted to form a flange 56. The ange 56 laps outside of a flange 58 which is part of an astragal. The astragal also has a sill ange'60.

The astragal, consisting of the flanges 58 and 60, may be inserted in the sash B, after the frame of the sash has been assembled and surface sanded in the usual way. Thus the outwardly projecing flange sill ange 60 and the inwardly projecting flange 58 do notinterfere with the sanding operation. The astragal provides means for draining water from the flange 56 of the ventilator secton 48 and also serves as a support for hinges 62 which are connected with the flange 58 and with the ventilator section 48.

The ventilator section 48 maybe swung in-` wardly to a position where it can engage the lower edge of the inner sash 44, as shown in Figure 2, so that a flue is provided for circulation of air, as indicated by the arrows d. Thus the air for Ventilating purposes f'lows into the building adjacent the top of the window frame and thus prevents any direct draft adjacent the lower part of the window frame. Direct draft can be had, however, by adjusting therventilator section 48 to the dotted line position', resting on the stool 10a of the window frame A.

For retaining the ventilator section 48 in closed or open inclined position, hardware may be provided, such as a mounting bracket 64, a slide bar 66 pivoted thereto and having notches 65 and a headed clamping pin 68. The bracket 64 is mounted on the frame of the storm sash B, while the headed pin 68 is attached to the ventilator section 48. The slide bar 66 has a notch 67 which alines with the head of the pin 68 for disconnecting the ventilator section 48 from the slide bar so that it can be moved to the dotted lineposition in Figure 2.

The degree of inclination of the ventilator section 48, of course, may be readily adjusted and retained and if it is desired to deflect air into the room just above the ventilator section 48, the inner sash 44 may be raised any desired distance instead of being in engagement with the upper edge of the ventilator section as shown.

The ventilator section 48 is made as wide as-possible so as to leave as little space as feasible between the side edges thereof and the sides of the window frame A, so that most all the air will be deected up past the upper edge of the ventilator section.

Some changes may be madeinf the constructionv and arrangement of the parts of my device without departing from the real spirit and purpose of; my invention, and it is my intention to cover by my claims, any modified forms of structure or5 use of mechanical equivalents, which may be reasonably included within: their scope.

I` claim as my invention:
