1 Claim.

This invention relates to new and useful improvements in storm windows for dwellings or the like, and it is among the objects thereof to provide a storm or auxiliary window structure in which the aperture frames are self-sealing and require no caulking after mounting in place.

Another object of the invention is the provision of aperture frames of a shape to receive the sash with the side frames adjustable relative to the head casing in a manner to be interlocking therewith.

Another object of the invention is the provision of a storm window design in which the aperture frame and sash frame are shaped to maintain a sliding fit to seal the joint while permitting adjustability of the sash frame relative to the aperture frame.

Still another object of the invention is the provision of aperture frames and sash frames of structural shapes designed to give rigidity and strength while permitting sufficient flexibility for relative alinement of the cooperating parts.

Still another object of the invention is the provision of an improved ventilator structure for use with the aperture frames having novel features of construction to render it accessible for cleaning.

These and other objects of the invention will become more apparent from a consideration of the accompanying drawing, constituting a part hereof, in which 1ike reference characters designate like parts, and in which Fig. 1 is a front elevational view of a storm window embodying the principles of this invention;

Fig. 2 a top plan View, partially in section, of a corner of the aperture frame taken on the line 22, Fig. 1;

Fig. 3 a front elevational View of the corner showing a special joint for interlocking the side aperture frames with the head casing, a section of which is shown in Fig. 2;

Fig. 4 an end elevational view of Fig. 3, viewed from the right-hand side of the drawing;

Fig. 5 a cross sectional view of the aperture frame, sash frame and sash;

Fig. 6 a front elevational view of the head casing and side frame assembled and joined;

Fig. 7 an end elevational view of the aperture frame of a type for receiving the sash without an intermediate sash frame;

Fig. 8 a cross sectional view of the structure of Fig. 7 with the sash disposed therein;

Fig. 9 a cross sectional view of an aperture 2 frame, sash frame and sash having interacting flange portions constituting baffles and illustrating spring means disposed between the aperture frame and sash frame;

Fig. 10 a similar view eliminating the interacting flange or bafile members;

Fig. 11 a vertical cross section through a ventilator as shown in Figs. 17 and 18 taken on the line Il-H, Fig. 17;

Fig. 12 to 16 cross sectional views of different forms of aperture frames embodying the sealing feature;

Fig. 17 a rear elevational tilator; and

Fig. 18 a front elevational view thereof.

With reference to Fig. 1 of the drawing, the numeral I designates vertical sash frames mounted on aperture frames 2 having a head casing 3, a ventilator 4 and a window sash 5 associated therewith. The sealer frame 2, as shown in Fig. 5, is a U-shaped member 6 having a straight leg I with a knife edge 8 and having a flange 9 with a knife edge In, the sealer frame being secured to the wood frame of a window by screws I I with the knife edges 8 and H1 seated into the wood frame l2 to seal along theentire periphery thereof. This construction eliminates caulking and further assures proper seating of the sealer frame 6 on the aperture frame of a building to provide rigidity and strength.

A sash frame l3, which is referred to in Fig. l as the head casing 3, is of substantially H-shape with a partition 14 forming a channel at the top which slidingly engages the U-shaped sealer frame 6. The depth of the channel of the H- frame and the sealer frame are such as to permit alinement of the sash frame i3 relative to the sealer frame 6 to position the sa h frame relative to the window sash which is designated by the numeral l5 in Fig. 5. The lower portion of the head casing or sash frame [3 is contracted to provide a slot iii of substantially the width of the sash IE to permit free sliding movement of the window sash in the sash frame l3. As shown in Figs. 2, 3 and 6, the side and head casings l and 3 of the sash frame may be jointed by slotting the head casing on the lines I1 and I8 and by notching the side casing at Hi. When they are joined as shown in Fig. 6, they may be secured by pins 20, the slotting functioning to interlock the head casing with the side casing of the sash frames.

In the form of the device shown in Figs. 7 and 8, the sealer frame 21 constitutes the sash frame for receiving the sash 22 as shown in Fig. 8.

view of the ven- The sash frame is provided with knife edges 23 and 24 which are pressed into the wood aperture frame of the building, and the frame 2| is secured by screws 25 as shown in Fig. 8,

The sash frames may be yieldingly mounted on the sealer frames by disposing spring elements 26 therebetween as shown in Figs. 9 and 10 or a leaf spring 26a shown in Fig. 5. In the form of the device shown in Figs. 9 and 10, the seal ing frames 27 and 27a are provided with the knife edge members 23 and 24 as shown in Figs. 7 and 8, but they differ from the structure of Fig. 5 by having open channels 23. The sash frame 29 of Fig. 9 is provided with an offset flange 30 which is disposed in a groove 3! of the window sash 32 forming a tortuous path or baflie for excluding the outside atmosphere. In the form of the device shown in Fig. 10, the window sash 33 abuts against an extension 34 of the sash frame 35.

Figs. 12 to 16 illustrate various shapes; and dispositions of sealer frames or sash. frames 2!, 2111,21, 21a and 27b, however they may be used, all being provided with knife edges 23 and 24 forseating in wooden aperture frames.

In Figs. 11, 1'7 and 18, ventilators 36 are mounted on the sealer frame 31 by a channel shaped cross-member having flanges 38a disposed over the legs 39 of the channel member 31. The outside wall of the ventilator is provided with louvered slots 40, and a screen 4| extends across offsets 42 and 43. The ventilator is provided with a movable wall 44 of sheet metal having an offset bottom flange that fits in a slot 45 of the ventilator to permit tilting movement as shown by dotted lines in Fig. 11. A latch 46 is provided to lock the inner wall in the ventilator frame as shown in full lines in Fig. 11. The inner' wall 44, when in its tilted position, provides screened ventilation and can be lifted out of the ventilator frame to render it accessible for cleaning of the screen. The top of the ventilator frame is shaped to coact with the bottom of the sash 47' of the window with which it cooperates.

In: the mounting of the storm window in the window aperture of a dwelling, the sealer frame 6 is applied with the knife edges embedded in the wood frame. The sash frames where used in the form of Fig. 5 are then mounted in sliding engagement with the sealer frames and the sashes are mounted in the sash frames as shown. The head casing 3 may be cut out as shown in Figs. 2 and 3 to receive the side sash frames I and interlock therewith as described. By means of the sealer frames and sash frames, standard metal frames may be applied to various sized window apertures by cutting them to length and joining the side frames with the head casings to interlock the sash frames and form a durable, air-tight assembly.

Although several embodiments of the invention have been herein illustrated and described, it will be evident to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.

I claim:

In a storm window structure, a sealer frame for mounting on the Wooden aperture frame of buildings comprising a U-shaped member, one leg of which is provided with a knife edge and the other leg extending into a horizontal seat with a knife edge on its outer extremity, said knife edges being adapted to pierce the wooden aperture frame to seal therewith.
