WINDOW CONSTRUCTION Filed March 8, 1948 ATTORNEY Patented Jan. 1, 1952 UNITED STATES PATE NT OFFICE This invention relates to improvements in window construction.

The principal objects of this invention are:

First, to provide a window construction which will admit a greater amount of light than the present standard type of window construction.

Second, to provide a window construction for dwellings and the like including a screen and storm sash which is particularly adapted for unit construction and shipment and which will require no fitting when installed in a building.

Third, to provide a window construction which will admit an increased amount of light and provide adequate ventilation at a reduced cost. Other objects and advantages pertaining to the details and economies of my invention will be apparent from the following description and claims.

The drawings of which there is one sheet illustrate a preferred form of my window construction.

Fig. 1 is an inside elevational view of my window construction as installed in a house.

Fig. 2 is an outside elevational view of my window construction partially broken away to illustrate details of construction thereof.

Fig. 3 is a fragmentary horizontal cross sectional view along the line 3-3 in Fig. 2.

Fig. 4 is a fragmentary horizontal cross sectional view along the line 4-4 in Fig. 2.

Fig. 5 is a fragmentary vertical cross sectional view along the line 5-5 in Fig. 5.

My window construction consists of a main frame including side members I, a top cross member 2, a bottom cross member or sill 3, and an intermediate cross member 4. The intermediate cross member is rigidly connected between the side members I as by a tongue and grooved joint 5 or other suitable fastening means and serves to strengthen the main frame and prevent bowing of the side members.

As is most clearly illustrated in Fig. 5 the intermediate cross member 4 is downwardly and outwardly sloped as at 6 on its upper surface and its upper inside edge is rabbeted as at 1. The lower cross member 3 is also outwardly and downwardly sloped in the usual fashion and is provided with horns 8 at its ends extending laterally beyond the side frame members I. My frame is adapted to be installed between the studding 9 of a building in the usual fashion and inner and outer trim or face boards l0 may be secured to the frame in the usual manner.

Above the intermediate cross member 4 the side members I are channeled as at H to re- 2 Claims. (CI. 20-52) ceive the parting strip I3 and molding strip l2 with the window pane l4 positioned therebetween. The rear edge of. the parting strip I3 is arranged flush with the forward edge of the rabbet groove 1 so that the window pane [4 seats against the parting strip and the outer edge of the rabbet groove. The top cross member 2 is grooved as at I5 to receive the upper edge of the window pane. The inner edge of the molding strip 12 is arranged flush with the inner edge of the intermediate cross member 4 so that the inner edge of the molding strip constitutes an outer guide for the lower movable sash Hi. The movablesash I6 is of standard construction and is provided with a lower window pane I1. The inner sash is retained against the molding, and intermediate cross member 4 by the inner guide stops l8 secured to the main frame members.

Below the intermediate cross member 4 and flush with the outside of the movable sash, the side frame members I are grooved to receive the lower ends of the molding strips l2 for guiding the movable sash in its lowered position. The mold strips I2 also form a blind stop against which the screen sash 2| may seat. The screen sash 2| is secured in place by suitable fastening such as the familiar spring pressed pin 22. Where desired a storm sash corresponding in size to the screen sash may be provided for interchanging with the screen sash.

All of the sash frames and parts for my window construction can be mass manufactured and assembled to fit the main frame which can also be manufactured in many standardized sizes and easily installed in a building. My window construction is thus adapted for economical mass production and shipment and requires little labor to be installed. The upper window pane I4 is considerably larger than the corresponding pane in present conventional window construction since there is no sash frame to reduce the size of the upper window pane. I have observed that the great majority of double sash windows presently in use have their upper sash frames stuck or frozen to the window frame by painting, both inside and out, so that no ventilation is lost by permanently securing my upper pane directly to the main frame of the window.

My lower window sash may be provided with the usual sash cord 23 and counter-balancing sash weight 24 but the expense of a duplicate sash cord and weight for the upper window is eliminated in my construction. I also eliminate the cost of a separate upper sash frame andguide strips for the upper and lower sash as the inner molding for the upper pane also serves as a guide for the lower sash.

I have thus described a highly practical form of my window construction but it should be understood that I do not limit my invention to the particular embodiment illustrated. Obviously the relative positions of the fixed pane and movable sash could be reversed and the parting strips and molding strips I3 could be vsecured directly to the side frame members I without setting them into grooves in the side frame members if desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. Window construction comprising, a main frame having side members and top and bottom cross members, an intermediate cross member fixedly secured between said side members and rabbeted on its upper inside edge, parting strips set into said side members above said intermediate member and with theirinside surfaces approximately flush with t-hevertical surface of the rabbet thereof, an upper window pane permanently secured against said parting strips and the vertical surface of the rabbeted portion of said intermediate member, a sash frame slidable in said main frame and along the rear side of said intermediate cross member, molding strips set against the inside of said pane and constituting outer guides for said sash, inner sash guides secured to said main frame, and lower sashguides set into said side members below said intermediate member with their outer sides constituting blind stops.

2. Window construction comprising, a main frame having side members and top and bottom cross members, an intermediate cross member fixedly secured between said side members and rabbeted on its upper inside edge, parting strips on said side members above said intermediate member and with their inside surfaces approximately flush with the vertical surface of the rabbet thereof, an upper window pane permanently secured against said parting strips and the vertical surface of the rabbeted portion of said intermediate member, a sash frame slidable in said main frame and along the rear side of said REFERENCES CITED The following references are of record in the file of this patent:
