INVENTOR. Henry A Taylor Maurice E. Sterne/ 1 READILY REMOVABLE WINDOW WITI-I WEATHER- STRIPPING This invention relates to removable windows, both pluralhung and single sash types having balance assemblies associated therewith and more particularly an improved window of this type in which the sash of the same is readily removable from the window casing and the sash and casing include weather-stripping to seal the window.

Single and double-hung windows having balance assemblies are well known and in use. Such windows have been made removable from a window casing. The prior patent of Dawson J. Dinsmore U.S. Pat. No. 3,358,404 dated Dec. 19, 1967 shows one version of such a window construction. This particular construction requires that the balance assemblies mount to and move with the windows and require special latches in the jamb channels to be operated to remove the sash therefrom. Generally, windows of this type require translational movement of the sash within the jamb channels and compressibility of the portion of the jamb channel to permit removal of the sash therefrom. This provides for sloppiness in fit between sash and jamb channel and leakage of air around the same. This type f construction does not readily permit the addition of weather-stripping thereto to seal the window. In addition, this particular type of construction is not applicable to metal windows.

The present invention in a removable window is applicable to single and double-hung windows and is particularly adapted to the use of metal window and sash construction. It provides a simplified and improved design of a window which of incorporates a balance assembly and in which both sash may be readily removable without translational movement of the same. Further, it provides an improved structure whereby the sash may be moved in any position in the window casing and further provides for a substantially rigid guiding mounting of the sash within the casing. It further provides an improved and simplified weather-stripping of the window sash in the window casing from the outside toward the inside sealing both sides of each sash surfaces for all positions of movement to effectively weather-strip the window. It further requires no special latches and permits a simplified and easy removal of the window.

Therefore it is the principal object of this invention to provide an improved removable window assembly with balances.

Another object of this invention is to provide an improved construction of this type particularly adapted for metal windows.

A further object of this invention is to provide a removable window assembly in which the sash may be moved in any position with respect to the window casing.

A still further object of this invention is to provide an improved window construction of this type incorporating weather-stripping.

A still further object of this invention is toprovide a readily removable window assembly incorporating balances which is simple in design, low in cost and easy to maintain.

These and other objects of this invention will become apparent from a reading of the attached description together with the drawings wherein:

FIG. 1 is a perspective view of a removable double-hung window embodying our invention,

FIG. 2 is a sectional view of the same taken along the lines 22 in FIG. 1 and with one sash removed and a second sash tilted outward for removal,

FIG. 3 is a sectional view of a portion of the casing of FIG. 2 taken along the lines 33 therein,

FIG. 4 is a rear view of a balance assembly of the improved removable window,

FIG. 5 is an elevation view of a sash with parts broken away to show the guide structures thereon,

FIG. 6 is a sectional view of the window casing and a portion of the sash with parts broken away taken along the lines 6-6 in FIG. 7,

FIG. 7 is a sectional view of a portion of the jamb as shown in FIG. 6 taken along the lines 7-7 therein,

FIG. 8 is an end elevation view of a sash showing the guide structures, and

FIG. 9 is an end elevation view of the catch for the balance assembly cord.

Our improved window with balance having a removable sash is shown in the drawings in connection with a doublehung window. The principles of the invention are equally applicable to single-hung windows and is preferably utilized in metal window construction. Thus in FIG. 1, the window casing is indicated generally at 10 as incorporating side jambs 12 and 14 connected to a head frame 16 and a sill frame 20 to form the general rectangular casing construction. The side jambs, head and sill frames are preferably made of an extruded aluminum and the parts are held together through suitable screws, such as is indicated at 22, extending through apertures in the head and sill frames and into the side jambs, as will be hereinafter described.

. The side jamb construction will best be seen in the elevation view of FIG. 2 and the sectional view of FIG. 6. Each jamb member has an outer and inner jamb channel, indicated by the numerals 24 and 25, and as will be noted from the cross-sectional configuration of FIG. 6 the outer or upper sash is of a shorter width dimension than the inner or lower sash in the double-hung window. The jamb construction or cross section is so formed as to define the respective channels 24, 25 by flanges 26, 27 and 28 extending transversely out from an irregular base plate portion 30. Flange 26 has a transversely extending guide portion 31 depending therefrom which defines one side of the channel 24 or recess. It further extends outwardly to include a channel shaped portion 32 which mounts the weather-stripping material which will bear against the outer sash. The same construction exists for flange portion 27. Thus, the flange portions 26, 27 with the guide portions 31 extending transversely therefrom define the recess which extends the length of the jamb channel and in which is positioned the balance assembly, indicated generally at 35. The inner jamb channel is similarly formed between the flange portions 27, 28 with guide flanges 31 extending transversely therefrom to define the opening or the recess forming the inner jamb channel 25 with the flange portion 27 having a weather-stripping portion 38 extending therefrom to bear against the inner sash. Positioned in the upper portion of each of the jamb channels are balance assemblies 35 which are identical in construction and are shown in detail in FIG. 4. It should be noted, however, that any particular balance construction may be employed which will fit within the recess and will have an outer projecting guide surface, such as is indicated at 40, for the purpose of guiding the sash thereon. The back side of the base plate includes extending rib portions 42 which are split and which receive the screws 22 holding the head and sill frame portions to the jamb members forming the sides of the casing. Each jamb member is identical in construction and when assembled with the head frame and sill frame define aligned recesses or channels on the sides of the casing to guide the respective sash therein. The sill frame is inclined toward the outside of the window, as will be seen in FIG. 2.

For the purpose of the present disclosure, the balance assembly which is employed and positioned in each of the jamb channels on either side of the sash is shown from the back in FIG. 4 to disclose one version of the same. It includes a generaliy U shaped or channel shaped metal structure 44 having the curved or guide surface 40 on the outer edge of the same and with a spring 45 connected at one extremity to a pin 46 positioned through the sides and secured thereto. The free end of the spring, as indicated at 47, mounts a pulley member 48 having a plurality of sheaths over which the sash cord 49 extends. At the opposite extent of the balance assembly is positioned a fixed sheath or pulley 50 which is rigidly mounted in the channel by means of a pin 52 extending between the sides of the same. The operation of the balance assembly is conventional with the sash cord extending over the plurality of sheaths of the pulleys 48 and 50 causing the floating pulley 48 connected to the free end of the spring 49 to move as the sash cord is drawn out from the confines of the channel member 44 forming the frame for the balance assembly. A pin 53 positioned at the upper end of the balance assembly provides the means by which it is secured in the jamb channel. Thus, as will be seen in the sectional view of FIG. 3, a bent flange portion 55 in the jamb channel at the upper end of the same bears against the pin 53 to secure the same in the recess or jamb channel mounting the same in a particular position near the upper end of the jamb channel. The free extremity of the sash cord 49 carries a hook member 60 which has a generally V or triangular shaped notch therein and a transversely extending flange 62 formed integral therewith with an aperture therein to which the end of the sash cord is knotted. The opposite end of the hook member has a toothed portion 63, for the purpose of which will be later noted. As will be hereinafter identified, the hook members are adapted to ride below a lower guide on the sash to apply a spring bias to the same in a conventional manner.

The individual sash are also preferably of a metallic construction being made of extruded parts and held together in assembled relationship to form the four sides or sides, top and bottom of the individual sash. The particular details of this construction form no part of the present invention except to include provisions for forming of weather-stripping and guides as will be hereinafter noted. Thus, as will be seen in FIG. 1, the upper and outer sash 70 which is smaller in width dimension than the lower and inner sash 75 is formed basically of side parts 72 with top and bottom frame parts 73, 74 respectively which are held together through any suitable means such as screws, as will be hereinafter identified. The side parts 72 are generally channel shaped on their outer edges as will be seen in FIGS. and 6. Each of the sash are generally of the same construction. On the inner facing surface of the channeled edges is a weather-stripping flange portion 80 which projects translationally from the channel edges and mounts the weather-stripping material. The latter bears against the transversely extending flange portions 31 of the jamb channel to seal the window at this surface. Positioned in the channel shaped edges of each of the sash are upper and lower guide members identified at 90 and 100, respectively. In the enlarged and broken away view of FIG. 5, the side shape of the upper guide member 90 is disclosed. The upper guide member 90, one of which is mounted on each side of each sash in the window, is a generally bifurcated member having a V shaped notch 92 therein with an inwardly projecting flange 93 at one edge of the same. It includes a flat plate like portion 94 attached to the other end of the bifurcated portion. The flange 93 fits into a slot in the top of the side 72 of the sash frame and on each side thereof with the upper guide member being secured thereto by a screw indicated at 96 threaded through an aperture 97 in the upper frame portion of the sash. The flat upper surface projects beyond the upper level of the sash and is notched as at 98 to fit into the ridge surface 40 of the balance assembly 35 and guides the sash thereon. The upper guide member is made of a plastic material and the portion of the same carrying the plate like surface or guide portion 94 is bendable or deflectable to permit the window to be rotated away from or over the projecting surface of the balance assembly upon removal. The lower guide member 100 is also a plastic part which is generally rectangular in base surface hav ing a projecting flange 102 at one edge thereof which fits through a slot in the lower frame part 74 of the sash and is secured thereto by a screw 103 threaded through an aperture in the lower end of frame 72 of the sash. This lower guide portion has a first generally triangular surface 105 projecting a short distance out from the main body portion of the guide and with a smaller triangular shaped surface or projection 106 extending therefrom throughout the remainder of the extent of the transversely extending portion. The screws 96 and 103, in addition to holding the guide members 90, 100 in place also connect the side parts 72 of the sash to the top 73 and bottom 74 parts of the sash to hold the same in assembled relationship. FIG. 8 shows the upper and lower guide members 90,

as mounted in the channel shaped edges of the sash as they appear on one edge of the same with the same construction being present on the opposite edge surface and for the upper and lower sash.

The frame parts when assembled include the suitable recessed surface 78 into which the glass pane 76 is positioned to be held therein through suitable rubber or vinyl mounting or glazing 77 or equivalent structure. These upper and lower guide parts are made to be plastic material, such as teflon, to provide a lubricated surface for ease in movement over the metal surface of the jamb channel and balance assembly. When installed, the lower guide will project into the recesses 24, 25 or the jamb channels to ride therein with the triangular surface forming the guide surface thereof. The triangular projection 106 of each guide 100 projects into the recess and below the hook member 60 of the respective sash cord such that the generally triangular portion of the hook conforms to the shape of the projection 106. In this position the flange portion 62 is level and the tooth projecting portion 63 is directed away from the sides of the recess and generally parallel thereto to permit the hooks to slide in the recess. A spring bias is thus supplied to the lower portion of the sash from the balance assembly in a conventional manner with the hook member sliding in the channel with window movement. The upper guides 90 ride on the projecting surfaces 40 of the balance assemblies 35 which are rigidly positioned in the extruded jamb channels so that no translational movement occurs therebetween. The flange portions 80 on each sash carry weather-stripping material to seal the surface of the sash in the jamb channel or window casing at the inner sides of the same with the weather-stripping flanges 32 and 38 in the jamb channel bearing against the outer surfaces of the respective sashes. Thus, the sash dimensions are such as to be slightly less than the distance between the exposed surfaces of the balance assembly so that the window may be readily removed. All draft or air movement will be sealed by virtue of the weatherstripping bearing against the sides of the sash and the sides of the jamb channel on the opposite surfaces thereof as will be best seen in FIG. 6. This inner surface of the head frame 73 mounts a pair of depending weather-stripping flanges 110 which are positioned to align with the outerjamb channels or the channel for the outer sash 70 so that the upper edges ofthe same will slide between the weather-stripping material therein to seal the window at the top thereof. The lower edge of the upper sash or the frame part 74 has a U shaped or L shaped projection extending across the same as indicated in FIG. 7. The upper surface of the lower sash 75 has a similar L shaped projection on its outer surface with suitable weather-stripping material 122 carried therein and in the closed position of the double-hung sash a weather-stripping layer appears between the sashes at the upper and lower edges respectively to seal the window at this point. Plastic blocks 123 are mounted on the upper sash 70 at the ends of the flange 115 to block the air passage around the ends of the interlock or flanges 115, 120. Further, the sill frame part 20 has weather-stripping flanges 125 aligned with the inner jamb channel for the lower sash 75 such that the lower edge of the same will be positioned therebetween. In addition, the lower sash has a transversely projecting flange portion extending from the lower frame part at an elevation slightly above the weather-stripping flanges 125 in the sill mounting part to provide a handle or grip surface for moving the lower sash in its track.

The hook member 60 has a toothed surface 63 as will be best seen in FIG. 9 which when the hook member is rotated with rotation of the sash will bite into the metal surface of the jamb channel or the side surface thereof to maintain the sash cord and hook member in an extended position when a sash is removed. Thus, upon movement of the sash up and down, the sash cord with a hook extremity of the same will follow the sash due to its positioning under the lower guide members 100 to apply a conventional spring bias to the sash to balance the same in this movement. Whenever the sash is to be removed from the casing, the upper edge of the same is gripped and the sash is rotated outwardly about an axis defined by the lower guide members 100. This rotation will cause the hook members to rotate in the jamb channel since they ride against the triangular surface 106. With rotation of the sash the hook members move to a position wherein the toothed surface will bite into the jamb channel and hold the hook 60 in position. The window is then removed by tilting the sash on'one of its guide members to clear the other lower guide member 100 from the recess or jamb channel permitting the sash to be lifted out of the window casing. Both balance assemblies on either side of the jamb channel will have the respective hook members maintained in the position of sash removal so that the sash can be reinserted and installed in the window casing by reversing the procedure. The compressible or flexible upper guide member 90 insures that the upper end of the sash will be guided on the exposed surface of the balance assemblies and the weather-stripping surrounding the sash and carried by the sash and jamb assembles, respectively, seal the sash on the sides thereof. The weather-stripping at the head frame part and on the sill frame part of the window casing similarly seal the upper and lower edges of the respective sashes in the closed position of the window.

The improved window assembly provides a simplified structure particularly adapted for metal window construction by means of which the sash may be mounted and positively guided in a window casing or in the jamb channels and yet may be readily removed therefrom for cleaning and maintenance purposes. The sash cords of the balance assemblies will be retained in a position where the sash may be reinserted so that the hooks will be underneath the lower guides on the sash to apply a spring bias to the same. The improved window construction provides a sealed unit in which the sash will be smoothly and firmly guided within the jamb channels or window casing preventing leakage around the same. The improved structure is particularly adapted for metal windows with extruded parts for low cost construction.

In considering this invention it should be remembered that the present disclosure is illustrative only and the scope of the invention should be determined by the appended claims.
