6 Claims. (Cl. 98--88) The present invention relates to improvements in window constructions and the primary object of the invention is to provide a window sash having a fixed upper glazed portion and a movable lower shield portion forming a closure for the lower portion of the sash and capable of being disposed in various adjusted open positions with respect to the upper fixed portion for ventilatin purposes, the entire sash structure capable of being readily mounted in a window frame of simple and inexpensive construction.

A further object of the invention is to provide a window which is devoid of sash cords and weights, and one wherein ventilation may be obtained without objectionable drafts entering the room.

A further object resides in the novel arrangement whereby the rockable and slidable ventilating shield will provide a weather tight construction when in closed relation in the sash.

A still further object resides in the novel means for screening the lower portion of the sash against entrance of insects when the shield is open, and permitting ready cleaning of the upper fixed glazed'portion of the sash.

A still further object is to provide a window sash of this character having an open lower portion closed by a rockable and removable shield portion which is also capable of being slid into overlying relation to the fixed upper portion of the sash.

Other objects and advantages of the invention will appear in the following detailed description, taken in connection with the accompanying drawings, forming a part of this specification, and in which drawings Figure 1 is a plan View looking at the inner side of the improved window sash with the ventilating shield in a closed position in the lower portion of the sash.

Figure 11 is a broken away view looking at the inner side of the supporting trough for the rocking deflecting shield.

Figure 12 is a fragmentary detail section showing one manner of securing the channel members to the end shields of the ventilating shield.

Figure 13 is a detail horizontal section thru the combined screen member and storm sash.

In the drawings and wherein like reference characters designate corresponding parts thruout the views, the letter A may generally designate the improved window sash and B a. window frame or other casing in which the sash is mounted.

The frame or casing B may be suitably mounted in a window or other wall opening C and comprises a plain rectangular frame or casing of wood or other construction in which the sash A is mounted in any preferred manner.

The sash A comprises parallel side rail 6, a bottom rail 7 and a top rail 8. Connecting the side rails 6 substantially midway of their height is a medial or parting rail 9 dividing the sash into upper and lower portions I9 and H respectively. The upper portion l6 may be termed the fixed or closed portion of the sash and is suitably glazed with glass as at l2, while the lower portion ll of the sash, below the parting rail 9 may be termed the open portion of the sash and this lower portion of the sash is provided with a rockable and slidable ventilating shield l4. and a screen member I5.

Referrin now to the construction and arrangement of the closure forming ventilating shield It, the same comprises a glass deflecting shield It provided along its side edges with metal channel members ll which embrace the ends of the shield and have triangular end flange portions 18 and I9 embracing the cut away corner portions of the glass shield. Extending inwardly in line with the web of each channel member I! is a lockin tongue or rib 2B which extends thruout the length of the channel. Associated with each end of the shield It is an end shield or wing 21 of segmental shape having an arcuate upper edge provided with notches 22, and provided along its outer edge with a right angular stop flange 23. These end shields 2|, as shown in Figures 5, '7 and 8, overlie the confronting faces of the side rails 6 between the bottom rail 1 and parting J rail 9 of the sash. As shown also in Figures 7 and 8, the side rails 6 are rabbeted as at 24 to receive the stop flange 23 and limit inward rocking of the shield I l.

Secured along the inner edge of each end shield or wing 2| is a channel member 25 including a U- shaped portion which embraces the edge of the wing, and these channel members may be secured to the Wings by striking lugs from the flanges of the U-shaped portion into the wing as at 26 in Figure 12.

Extending inwardly from the inner side of each channel member 25 are flanges 21 and 28 which form guides for the ends of the shield M to slide in. The flange 28 along the inner edge of the wing 2| is of L-shape and has its free edge directed toward the flange 21 to form a slot for receiving the tongue 20. Extending from the outer side of each channel member 25 is an L- shaped flange 29 forming a slot into which the inner edge of a facing plate 39 extends when the shield is closed as in Figures 7 and 8. These facing plates 3|] extend along the confronting faces of the side rails 6 between the bottom rail 1 and parting rail 9. The side rails 6 are rabbeted as at 3! to form a slot into which the flange 29 extends when the shield is closed, This interfitting of the plate 321 and flange 29 renders the assembly draft proof when the shield is closed.

Secured to the bottom rail 7 with its ends extending into the lower ends of the rabbets 3| is a trough 32 in which the ventilating shield i4 is rockably supported. This trough 32 may be formed from sheet metal and includes a bottom wall33, a vertical wall 34 along the outer edge of the bottom wall, and a divergent wall 35 along the inner edge of 'the bottom wall. The wall 34 terminates short of the ends of the trough to accommodate the end shields 2| and flanges 2], while the wall 35 extends into the rabbets 3|. The ends of the trough are closed by end walls 35. A strip of rubber or other yieldable material 3'! may be disposed in the bottom of the trough for the glass shield I6 to rest upon and form a weather tight arrangement.

Recessed into the inner face of the parting rail 9 is a rubber or felt cushioning and sealing strip 38 against which theshield l abuts when in a closed position. Thus, when the shield I6 is closed, the same is sealed at its upper and lower ends by the strips 38 and 31 respectively, and along each side edge by the interfitting'of the plate 3|! and flange 29. Secured to the under side of the parting rail 9, adjacent each end of the rail, is a keeper 39 each having a spring urged ball normally urged against its adjacent end wing 2! and adapted to engage in the notches 22 for retaining the ventilating shield in various adjusted positions. A handle all is secured to the upper flange portion I8 of each channel member H by means of a screw or the like 4|, and these screws also serve to clamp the members I! to the glass shield. These handles ll] serve as pulls for rocking the shield.

Secured to the lower flange portion l9 ofeach channel member I! is a lift handle 42. These handles 42 are secured by screws 43 which also serve'to clamp the members I to the glass shield. The cut-away corner portions I6, shown in Figure l, at the lower edge of the shield l6, together with the flange portions l9, provide chambers for receiving sliding lock bolts 44 normally urged toward the ends of the shield by springs 45 enclosed in the handles 42. These bolts M extend thru openings in their respective channel members l1, and when the shield I4 is in a closed position, have their ends projected thru the end shields 2i and into openings 46 in the side rails 6. Thus the bolts d4 serve to lock the shield I4 against sliding and rocking movement. Suitable handles 4'! serve for operating the bolts 44.

Secured in each of the inner rabbets 3| of the side rails 6 in alignment above each of the channel members is a guide channel 59. These guide channels are open at their confronting sides and are adapted to slidably receive the channel members H of the deflecting shield I6 when the shield is raised in the sash as in Figure 3, into overlying relation to the glazed upper portion of the sash. These guide channels are formed with grooves 5! in which the ribs 20 slide and prevent lateral shifting of the shield, as shown in Figure 9. When the shield is in a raised position, the bolts 44 are projected into openings 53 in the side rails B for retaining the shield raised.

Thus the ventilating shield |4 may be rocked in the trough 82 for controlling the air entering thru the lower open portion of the sash, and the deflecting shield l6 may be slid upwardly in the sash to provide a fully open lower sash portion. It will be observed that the shield IE slides in the end wings 2| upwardly into the guide channels 50.

Referring now to the screen member [5, the same is mounted in the lower open portion H of the sash between the end wings 2| of the ventilator shield so as to swing outwardly of the sash. The screen member |5 comprises a frame 55 fitting in the outer side of the sash A and disposed entirely within the plane ofthe sash, as shown in Figure 5. The upper rail of the frame 55 fits in a rabbet formed in the under side of the parting rail 9, while the lower rail of this frame fits in a'rabbet formed in the upper side of the bottom rail 1 of the sash. One side rail of the screen frame carries hinge eyes 56 at the outer side of the rail for receiving hinge pins 51 provided'on hinge plates 58 secured to the sash rails and 9. The top and bottom rails of the screen frame, adjacent to the opposite side rail, are provided with spring latches 59 having latch bolts adapted to be projected into latch openings 60 provided in the sash rails and 9 for retaining the screen memher in a closed position in the sash opening. A

suitable screening 6| such as screen wire or the like, is secured over'the outer side of the frame 55 as by a; wire retainer 62. a

The screen member I5 is also adapted to serve as a storm sash when desired by the insertionof a pane of glass 63 into the frame. Theframe 55 is provided'at the inside of its marginal rails with an inwardly opening channel 64 in which-is disposed a sealing strip 65, such as of rubber, felt or the like, and against which the glass 63 seats and is removably retained as by means of suitable retaining means 66. a As shown in Figures '7 and 8, the screen memher is is disposed between the end shields 2| so that these shields may pass between the ends of the screen member and the side rails of the sash frame upon rocking of the ventilating shield, As shown in Figure 6, the end shields 2| are of such width at their lower portions as to extend between the ends of the screen and sash side rails and thus close the space between the ends of the screen and the sash side rails.

Thus when the ventilating shield I4 is in a lowered position, as in Figures 1 and 2, the shield may be rocked to provide various degrees of ventilation, and when the deflecting shield I6 is in a raised position as in Figure 3, full ventilation may be had thru the lower portion l l of the sash. Also, when the shield I6 is raised, in the screen member l5 may be swung out to permit ready cleaning of the outside of the upper glazed portion It of the sash.

While the channel members 25 have been shown as metal members secured to the inner edges of the end wings 2!, which are preferably formed of a suitable plastic material, these channel members 25 may also be formed of a plastic material and made as an integral part of the end wings. Likewise, various other portions of the structure may also be formed of plastic materials whenever such is found practical and desirable.

Changes in detail may be made to the form of the invention herein shown and described, without departing from the spirit of the invention or the scope of the following claims.
