6 Claims.

My invention relates to storm windows which are mounted to enclose the usual windows of a building and has particular relation to storm windows of the type adapted to be mounted on easement windows.

A storm window constructed in accordance with the teachings of the prior art of which I am aware consists of a rigid transparent assembly adapted to be securely mounted either inside or outside of a building on the frame of a building window which it is to enclose. The frame of the storm window assembly is sealed to the frame or the building window; but the joint includes breather vents, and particles of soot, dirt and other foreign materials seep in through the vents with the air which circulates between the windows and become deposited on the transparent surfaces which bounds the space between the windows. It is essential that both surfaces of the building window and the storm window be` cleaned periodically. The external surfaces of both windows can be handled with facility but the surfaces bounding the space between the windows is not readily accessible.

In cleaning storm windows constructed in accordance with the teachings of the prior art, it is necessary to remove the storm window entirely from the building window. Such removal involves serious inconvenience and difficulty, and often, because o f the ineptness of the person who cleans the windows, may result in fracture of either the storm window or the building windows.

It is, accordingly, an' object of my invention to vprovide a storm window assembly which shall readily permit cleaning of the surfaces bounding the space between the building window and the storm window without vremoval ofthe storm window from the building window.

Another object of my invention is to provide a storm window assembly which when in use may be readily cleaned completely without serious inconvenience or diiculty.

A further object of my invention is to provide a novel storm window construction. l An ancillary object of my invention is to provide a novel'hinge.

f In accordance with my invention, I provide a storm window assembly in which the transparent portion of the storm window is hinged to the frame on which it is supported. This frame is designed to be secured to the frame of the building window and the hinge assembly in accordance with my invention, is so conceived that its bearing is provided in the frame of the storm Window and its hinge rod is secured to the transparent portion oi the window.

The storm window is repeatedly opened and closed during cleaning and is otherwise subject to substantial wear. In accordance with a specie aspect of my invention, then, the hinge is of sturdy construction including a single hinge rod which extends throughout the length of the bearing. Such a long rod would have a tendency to bind but this tendency is suppressed by thrust bearings provided at both ends of the rod. The hinge bearing is provided with a positive stop which preventsrthe window from swinging over too great an angle. This stop positions the storm window conveniently for cleaning and prevents damage to it by its abruptly being thrown open by an attendant;

Storm windows of the type involved in my invention are preferably composed ofy aluminum or aluminum alloys. Such metals have a tendency to oxidize. To suppress any locking or binding effect by reason of the oxidation, the hinge rod, in accordance with my invention, is provided with scraper edges which remove any oxidation from the bearing. The hinge rod is also provided with grease grooves so that the bearing is maintained welllubricated.

The entire hinge is mounted within the frame of the storm window assembly and there are no external projections. The transparent portion of the storm window is maintained closed by a spring loaded latch whichy firmly holds this portion against the frame.

The novel features that I consider characteristic of my invention is set forth with particularity and in the appended claims. My invention itself, however, both as to its organization and its method of operation, together with additional objects and advantages thereof will be understood by reference to the following description and to the drawings, in which:

Fig. 6 is a view in front elevation of another portion of the storm window in accordance with my invention with a part broken away; and

Fig. 7 is a fragmentary view partly in section showing a. modification of my invention.

The structure shown in the drawing comprises a supporting frame 1 adapted to be mounted on the frame 9 of the building window II to be covered. The frame 1 is of rectangular shape and has four sides I3, l5, I1 and I9. The sides are of composite contour but of generally trapezoidal longitudinal cross section, the ends being at an angle of 45 to the longest side. The dimensions of the sides are such that the shorter sides I1 and I9 may be disposed between the longer sides I3 and I5 in edge-along-edge engagement. One edge each of the sides I1 and I9 are bra-Zed to the edges of the side I3 and the other edges of each are held in engagement with the side I by corner gussets 2I which are staked at 23. A rigid frame is thus formed.

While the frame shown in the drawings is brazed at two corners and gusseted'at the other two, frames formed in other Ways are within the scope of my invention. All four corners of the frame may be brazed or all four corners may be gusseted.

The long side I3 of the frame 1 consists of an elongated rectangular strip 25 along which a hollow slot or channel 21 having the cross section of the segment of a circle extends. A supporting ange 29 projects from one edge of strip 25, and a strip 3I of substantial area extends from the other end. The flange 29 and the strip 25 together constitute a right angle bracket. The iiange 29 connects with the strip 25 through a web 33 at right angles with it which is integral with the flange on one side and with the strip on the other. There is a notch 35 which serves a breather vent in the web 33. The flange 29 has bevelled edges and when mounted on the building window is sealed into a suitable plastic seal 31, which securely engages the frame 9 of the building window. The ange 29 is also secured to the frame 9 of the building window by a plurality of machine screws 39.

The other long side I5 of the frame 1 consists of a similar strip 4I having a hollow slot or channel 43 from which a supporting flange 45 projects. As in the case of the other side, a web 41 extends between the flange l5 and the strip 4I and includes a breather vent 49. The strip 4I also has a lip 5I of substantial area. The shorter sides I1 and I9 are also provided with iianges 53 and 55, respectively, which are sealed to the frame 9 of the building window in the same manner as the flanges 29 and 45 of the longer sides I3 and I5.

The transparent portion of the storm window consists of a frame 59 within which a translucent surface 6I such as glass is sealed. This frame 59 is mounted on the supporting frame 1 in such manner that sides 63, 65, 61 and 69 of the window frame are parallel to corresponding sides l 3, I5, I1 and I9, respectively, of the supporting frame 1, and one of the surfaces each of the sides 63 and 65 rests against the lips 3| and 5I, respectively.

The frame 59 is joined to the long side I3 of the supporting frame 1 through a hinge rod which is of generally circular section and is pivotally mounted in the slot 21 of this side. A bracket 13 extends between the hinge rod 1I and the corresponding side 63 of the window frame 59; the bracket 13 is integral with the hinge pin 1I and is secured to the frame 59 by screws holding the frame 59 against the lip 3I. This bracket 13 is bent substantially at right angles between its junction with the hinge rod 1I and its mounting on the frame 59. The boundary 19 of the slot 21 remote from the frame 59 is at an acute angle to the adjacent surface 11 of the bracket 13 and when the bracket is rotated with the hinge rod 1I it engages this surface 16 and is stopped from pivoting beyond it. The angle between the surfaces 'f6 and 1'! is such that the storm window SI may be pivoted out to a convenient position for cleaning and the coaction of the surfaces 16 and 11 holds the storm window in this position while it is being cleaned.

The hinge rod is provided with one or more grooves 19, the sides of which terminate abruptly at the slot 21. .As the hinge rod rotates, the engagement of the edges of these grooves 19 with the slot tend to clean the slot, removing oxides and other foreign particles. The grooves 19 also serve for lubrication purposes holding a lubricant between the rod 1I and the slot 21.

The hinge rod 1I extends along the whole length of the slot 21 and to prevent binding of the long hinge rod, bronze end bearing studs 8l and 83 are provided. These studs 8l and 83 engage the ends of the hinge rod on one side and the adjacent edges of the sides I1 and I9, respectively, of the supporting frame on the other.

Where a gusseted structure to the side I3 is used, the ends of the gussets projecting along side I3 may serve as thrust bearings. This structure is shown in Fig. '7. In Figure 7 the ends of hinge rod 1l are shown as bearing simultaneously against the ends of gussets 2l, which are located partially within the channel or slot 21.

Here, the gussets 2I perform the function of end bearings 8i, 83 in Figure 4.

On the opposite side 91, the frame of the window is provided with a latch 81. This latch comprises a pin 39 which is slidably mounted in the frame 59 near the center of the side 91 and carries at its external end a cup shaped projection 9I rigidly secured thereto. The pin projects through a notch in the lip 5I. This pin is held in its outermost position by a spring 93 which engages the inner surface of the cup 9| at one end and a washer secured to the side 59 at the other. At its internal end, the pin carries a locking hook 91 which engages the lip 5I extending from the strip 4I and under the action of the spring 93 holds the frame 59 in engagement with the strip 4I.

With the hook 91 engaging the lip 5I of the adjacent strip 4I, the window is in the closed position. The hook 91 may be disengaged from the strip 4I by compressing the cup-shaped portion 9| and turning it. The window assembly may then be pivoted outward to the angle determined by the limiting stop 16. The surfaces of the building window I l and the storm window 6I which bound the space between the windows may thus be readily cleaned without damage to either of the windows.

The storm windows may be mounted to pivot in different ways depending on the structure of the building windows. A storm window may swing about the edge (9) of a building window along which the building Window is pivoted, that is, the hinge of the storm window may be substantially coaxial with the hinges of the building window. Such an arrangement is used where two building windows covering an opening are arranged to swing away from their joint, one clockwise and the other counterclockwise. The storm window may also be arranged to swing about a hinge mounted along the edge of the building window which is opened. Such an arrangement is used where the building windows which open are disposed adjacent a picture window and the sides of the building windows along the picture window swing away from the picture Window. Where a storm window covers a transom window, the storm window may be horizontally hinged. The storm window for a picture window is also customarily horizontally hinged with the storm window swinging upward from the lower side of the picture window.

An important feature of my invention is the continuous hinge. This hinge has a length corresponding to the length of the side of the building window along which it is mounted. For long storm windows it is correspondingly long. The hinge therefore is in all situations capable of supporting the storm window.

While I have shown a certain specific object of my invention, I am fully aware that many modii'lcations thereof are possible. My invention, therefore, is not to be limited except insofar as is necessitated by the prior art and by the spirit of the appended claims.
