2 BY LOU HINDIN Z TORNIEY United States Patent WOODEN FRAME STORM SASH FOR CASEMENT TYPE WINDOW Lou M. Hindin, Philadelphia, Pa.

Application January 26, 1955, Serial No. 484,139

2 Claims. (Cl. 20--55) My invention relates to storm windows, and more particuarly relates to storm windows with removable inserts for casement type windows.

In my invention, the storm window frame is fabricated of wood, metal, or plastic so that it may easily be attached to the inside face of a casement type window casing and the removable glass and screen sashes lie flush within the wood frame and are slidably supported. Means are also furnished for providing an adjustable deflector type ventilator.

Heretofore, casement windows were provided with outside storm sashes which were bulky in appearance and difficult of application and removal. Although the known forms of inside metal frame storm windows solved some of these difficulties, they also have other objectionable features that limit their coverage and performance.

It, therefore, is an object of my invention to provide a storm window frame having removable window glass and screen inserts for casement type windows which can readily be installed as a unit from the interior of the building.

Another object of my invention is to provide a storm window frame for casement type windows having inserts of single panel glass and which also may embody a ventilator opening.

Another object of my invention is to provide a storm window for a casement type window that provides the greatest coverage of both glass and metal of the prime window using the least amount of space in obtaining this object.

Another object of my invention is to provide a compact storm window which does not disfigure or mar the prime casement window.

Other objects of my invention are to provide an improved device of the character described, that is easily and economically produced, which is sturdy in construction, and which is highly efiicient in operation.

With the above and related objects in view, my invert-- tion consists in the details of construction and combination of parts, as will be more fully understood from the following description, when read in conjunction with the accompanying drawings in which:

Fig. 1 is an elevational view of the interior of a casement type window casing and a wooden, metal, or plastic storm window frame for the aforementioned casement showing a typical mounting of storm window, screen, and ventilator inserts embodying my invention.

Fig. 2 is a sectional view taken along lines 22 of Fig. 1.

Fig. 3 is a sectional View taken along lines 3-3 of Fig. 1.

Fig. 4 is a sectional view taken along lines 4-4 of Fig. 1.

Fig. 5 is a side elevational view of the easement type storm window embodying my invention showing the upper storm window insert in position and the ventilator in an open position.

Fig. 6 is a close-up fragmentary view showing the Patented Nov. 22, 1955 manner in which the upper storm window insert is held in position within the storm window frame on the frame Clasps.

Fig. 7 is a fragmentary view of the easement window latch mounted adjacent the storm window frame showing the manner of operation from the interior of a building.

Referring now in greater detail to the drawings, in which similar reference characters refer to similar parts, I show a casement window of the conventional type comprising vertically-pivoted, outwardly swinging casement sash, generally designated as A, mounted within a window casing, generally designated as B.

The casement type sash A is vertically pivoted upon hinges 10 so as to swing in a horizontal direction. Each hinge is comprised of a leaf 10A which extends in an outward direction from the casement sash A, and a cooperating leaf 10B which extends in an outward direction from the casing B, the leaves 10A and 10B being pivotally connected to one another by a pin NC. A manually operated crank 12 located interiorly drives a worm gear (not shown) for regulating the opening and closing of the swinging sash from the inside by means of a connecting pivotally mounted lever arm 14.

interiorly spaced from the sash A when in a closed position and amxed to the window casing B is a storm sash embodying my invention.

The storm sash comprises a wooden, metal, or plastic frame, generally designated as D, which is a permanently affixed frame and has included therein removable inserts, each of which is generally designated with a primary letter E.

The wooden, metal, or plastic frame D is permanently afiixed to the casing B by means of screws or nails and is finished with wooden moulding along the edges. The frame D comprises two vertical side uprights 16 which are mortised to an upper horizontal brace it; and a lower horizontal cross member 29. The upper horizontal brace 18 and the lower horizontal cross member are connected by a central vertical support 22 defining two openings 24 for the removable inserts E. The lower horizontal cross member is slotted and capped with metal or wood plates 26 which contain holes 28 adapted to receive and provide a weather-tight seal for the cranks 12 Vertically swinging latching levers 36 are pivoted at 32 to the central vertical support 22 at the interior of frame D for releasably interlocking engagement with a companion catch 34 mounted upon the interior face of the easement sash A and designed to draw sash A firmly against the window casing B from a point inside the storm sash within the building.

The vertical side uprights 16 and the central support 22 are rabbeted adjacent to openings 24 and facing interiorly to define vertical rails 36 with edges 36A for slidably supporting the removable inserts E. The upper horizontal brace 18 is notched adjacent to openings 24 and facing interiorly to form horizontally extending rabbets 38 whose vertical sides 38A lie .in the same plane as the vertical rails 36 but whose horizontal edges 38B are indented to a greater extent than edges 36A. Sheet metal flanges 40 are fastened to the interior face of the horizontal brace 18 adjacent to openings 24 and are curved slightly at its bottom portion in an inward direction to form deep, horizontally extending slots 42 having lips 44.

The lower horizontal cross member 20 is rabbeted adjacent to openings 24 and facing interiorly to form notches 46 whose vertically extending shoulders 46A lie in the same plane as rails 36 but whose indented bottom 46B extends slightly below the bottom portion of the opening 24. Horizontally extending inwardly curved lips 48 are mounted upon the inner face of the horizontal cross member 2t} adjacent to notches 46 to define a shallow lipped recess 50.

The removable inserts E comprise four types: an upper storm window El, a ventilator E2, a full screen insert E3, and a full glass storm window insert (not shown).

The upper storm Window insert E1 comprises a central glazed portion 52 and a surrounding extruded metal frame 54. The metal frame 54 has a specially designed bottom cross piece 56 with a downwardly projecting tongue 58 whose engaging surface 58A is flush with interior surface 56A of cross piece 56 from which the tongue 53 extends. Horizontally extending beyond the frame 54 and mounted upon its interior surface 56A are a pair of latching ears 60 which are adapted to engage with a pair of vertically clasping lugs 62 screwed to the interior face of vertical uprights 16 and central support 22.

The ventilator E2 comprises a central glazed portion 64 and a surrounding extruded metal bezel 66. The bezel 66 has a pin 68 which engages a chain 70 which, in turn, is mounted to the upright 16. The chain 70 holds ventilator E2 in an inwardly open position when the bottom of the ventilator is hingedly located within the shallow lipped recess 50.

To introduce the upper storm window insert E1, it is interiorly canted from top to bottom and while its upper edge rests upon the vertical rails 36, the top of the insert is slid beyond the relieved lip 44 into the deep slot 42 until stopped by horizontally extending edge 383.

While still pressed against the rails 36 and edge 38B, the upper insert E1 is swung in a vertical plane fiush against the rails 36 and then dropped until the horizontally extending latching ears 60 engage the vertical clasping lugs 62. The uppper portion of the insert E1 is maintained against the rabbeted edge 38A by the inner face of flange 40.

To maintain the ventilator E2 in a closed position, the upper storm window insert E1 is slid up into the clearance of slot 42 and the horizontally hinged ventilator is swung against rails 36. The upper insert is then lowered until its lower edge rests upon the upper edge of the ventilator E2 while the downwardly projecting tongue 58 grasps the upper interior portion of ventilator E2 maintaining it flush against the side rails 36. The vertical clasping lugs 62 provide a wedge for the latching ears 60and prevent rattling of the upper insert E1 and the ventilator E2.

The full screen insert E3 is introduced into the frame D by inclining the insert against rails 36 within the slot 42 and swinging the insert into a vertical plane. The insert E3 is then lowered into a locked position within the lower shallow slot 50. The full glass storm window insert (not shown) is similar to the full screen insert E3 and is mounted in a similar manner.

Although my invention has been described in considerable detail, such description is intended as being illustrative rather than limiting, since the invention may be variously embodied, and the scope of the invention is to be determined as claimed.
