Claims. 1

This invention relates to new and useful improvements in window structures and the primary object of the present invention is to provide a window structure including a plurality of outwardly swingable closure members together with a manually actuated lever for simultaneously raising all of said closure members.

' Another very important object of the present invention is to provide a window structure including a group of unitarily swinging closure members and a means for retaining or locking the closure members in a selected raised position and against accidental closing.

A further object of the present invention is toprovide a window structure composed of a plurality of outwardly swinging closure members with the adjacent horizontal edges of adjacent members being rabbeted to permit interlocking of adjacent members when they are in their closed position.

A still further aim of the present invention is to provide a window structure that is quickly and readily assembled or disassembled in a convenient manner, and which is neat and attractive in appearance, strong and durable in use, simple and practical in operation, inexpensive to manufacture, and otherwise Well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

- a. Figure 1' is a front view of the present invention; partly in elevation and partly in section;

Figure 2 is a side elevational view of Figure 1 and with dotted lines showing the closure members raised to their maximum position and the actuating lever lowered to its maximum position;

Figure 3 is a longitudinal vertical sectional view taken substantially on the plane of section frame composed of a pair of vertical side rails I2 and I4 having upper and lower grooves I6 and I8 in their inner faces and adjacent their ends that receive the ends of upper and

lower cross rails

20 and 22.

A plurality of closure members or window sashes 24 are associated with the frame and are mounted upon the frame for-vertical swinging movement in a manner now to be described. The

ends of the closure members 24 ,areprovided with recesses 26 that receive'anchor plates 28. The plates 28 are held in the recesses 26 by fasteners 30 that extend through the plates and into the ends of the closure members. Y.

The plates 28 are located relatively close to th upper edgesof the closure nriemliners and the plates 28 hold thev reduced threaded inner ends of horizontally projecting trunnionsor pivots 32 having splined outer ends 34. 7 1, The side rails I2 and I4 are provided withvertically spaced horizontal openings 36 in each of which there is fitted a hearing sleeve 38. The sleeves 38 rotatably support the trunnions 32 and the ends 34 of the trunnions project-outwardly from the side rails I2 and I4 to ,e nter splined openings 40 in the enlarged ends 42' of connecting arms 44. Set screws 46 threaded in'the ends 42 bear against the ends 34 of thetrunnions to hold the arms 44 on the trunnions. I ,l I The adjacent horizontal edges of adjacent closure members are rabbeted as at R, to permit interlocking of adjacent closure members when the closure members are moved to their closed position as shown in Figure v3. Y

The lower most of the openings 36 in the side rails are located below andparallel to the crossrail 22 and the bearing sleeves 38 therein rotatable support a strengthening rod or rock shaft 48 whose splined ends project from the rails I2 and I4 to support lower arms 45 similar to the arms 44. 1 j

A connecting bar 50 is pivoted, as at 5|, to each of the arms 44 that aremounted on the trunnions projecting through the rail I2 and to the arm 45 on one end of the shaft 48. Another connecing bar 52 is pivoted, as at 54, to each of the arms 44 that are mounted on the trunnions projecting through the rail I4 and to the arm 45 on the other end of the shaft 48. 7

An actuating lever 54 is pivoted, as at 56, to the rail I2 at a conveniently accessible position and is attached to the bar' 50 by a horizontal pivot 58 so that a lowering of the-lever 54 will effect a raising of the bar 50, directly, and will cause the closure members and the bar 52 toalso be raised. The opening in the lever 54 through which the pivot 58 extends; is sufliciently large as to permit the lever to be manually urged horizontally or laterally of the-rail I2 and the bar 50 for a purpose later to be described.

The free upwardly curved end portion 60 of the lever 54 supports a finger grip or knob 62 which permits a convenient handling of the lever during raising or lowering of the closure members.

Means is provided for locking the closure memlever 54 and a vertical slot 69 is provided in the.

trim T to prevent the lever from springing out of place.

The upper rail 20 supports a horizontalsealing strip that will contact the upper rabb'eted edge ports a lower'sealing strip 12 that will contact the lower rabbeted edge of the lowermost closure member when the lowermost closure member is in its closed position/as shown in Figure 3, toproperly seal 'theclosure's to the frame and to each. Obviously additional vertical resilient sealing strips may be applied to =the inner faces of the rails l2 and to :close the slight space between the ends of the closure members and the rails 12 and I4. M

The rails l2, i4, 26 and 22 are provided with ribs 74 to which there is secured a screened frame member 76. The frame member 16 is readily removed and may be replaced by a storm sash during cool weather. I

The recesses 26 extend to the upper edges of the sash so that when the sash is open; the fasteners 30 maybe'removed and the sash slipped from the plates'28 without having to remove any other parts.

The's'a'sh may be easily cleaned from the inside of the building by simply removing the screen. Also, the window structure is ofan awning type that will provide full ventilation as well as refleeting the sun out or the room. Furthermore, the sash may remain open during a Windstorm.

Additionally, there are no rods, bars or anything to obstruct the view through the sash nor is there anything to collect dust or mar its beauty except one small knob used for opening and closing the sash. 1

Having described the invention, what is claimed as new is:

1. A window structure comprising an open frame, a plurality of vertically swinging closure members mounted on said frame, connecting means between all of said members for simultaneous swinging movement of all of the members, a lever pivoted on said frame and also pivoted to said connecting means and manually actuated to simultaneously raise said closure members, and means carried by the frame and engaging said lever to retain the closure members in a selected raised position, said lever engaging means including an angle member having vertically disposed flanges, one fiang'e 'of said angle member having a plurality of vertically spaced notches for selectively receiving said lever. V

2.

4. A window structure comprising an open frame including a pair of vertical side rails, a plurality of closure members within said frame and including ends paralleling said rails, anchor plates secured to the ends of said closure members, horizontally projecting trunnions securedto said plates and extending through. said rails, each of said trunnions having an outer splined end projecting from said rails, connecting arms having splined openings receiving the splined ends'of said trunnions, a first connecting bar pivoted to the arms on the trunnions extendingthroug'h one side rail, a second connecting bar pivoted to the arms on the trunnions extending through the other side rail, a rock shaft on the frame paralleling the trunnions and pivoted to both bars, an actuating lever pivoted on said frame and also pivoted directly to said first bar for raising said closure members, and a vertical retainer on said frame adjacent said first ,bar and including a flange having a plurality of vertically spaced notches for selectively receiving said lever to retain the closure:members in a selected raised position. i
