July 10, 1956 L. CARNICK BASEMENT WINDOW CONSTRUCTION Filed Jan. 7, 1954 INVENTOR. A y; r 6'? raw/ck United States Patent 2,753,964 BASEMENT WINDOW CONSTRUCTION Lyle Carnick, Detroit, Mich., assignor to Copco Steel & Engineering Company, Detroit, Mich., a corporation of Michigan Application January 7, 1954, Serial No. 402,692 3 Claims. (Cl. 189-69) This invention relates to a basement window construction and more particularly to a basement window having a removable ventilator installed in a frame, the ventilator having means to balance to control of the ventilator in opening, closing and locking the same in the frame, the control means also embodying the locking mechanism.

The instant invention employs metal frames and ventilators, but the construction is also applicable to wooden units. Most basement window units are arranged with center mounted locking levers or devices. When these levers are grasped to open or close the ventilators, the control is very uncertain, precarious and often ineffective, because the ventilator can swing to either side of center thus going easily out of control in opening or closing operations. Ventilators of metal are often quite heavy in weight, being fitted with glass panes and sealing putty. Also, excessive loading of the frame top bar causes difficulty in operating such center lever locking devices, which often become jammed or distorted. A further difficulty in control is the fact that basement Windows are located near the basement ceiling or joist line, above the heads of most persons. Very often ventilators are dropped out of frames or improperly locked or jammed in their frames because the locking lever is located in the middle of the ventilator.

Side arm connected window ventilators are also difficult to control in that the disengaging arm slots must be very carefully positioned at both sides of the ventilator before the latter can be freed of the arms. This often is difficult because a view of the arm slot positions is not always possible, and then the operation is accomplished by feeling the arm slots with respect to the ventilator. These side arm problems are completely absent from the instant invention, where the control and locking means are clearly visible and simply operated.

To avoid such difiiculties, the present invention provides control of the ventilator at both sides, where the control locking handles are grasped by the person who is installing, opening or closing the ventilator. The handles further serve as locking levers, and because they are positioned at each side of the ventilator, the closure is positive and distortion of the ventilator and/ or the frame is avoided.

It is therefore an object of the invention to provide a basement window construction in which the window ventilator is arranged to tilt and open from the top, control and handles means being provided at each side thereof. Another object is to provide control and handle means that function also as locking levers. Still another object is to provide a ventilator that is independent of the window frame when the control locking means are disengaged therefrom. A further object is to produce a window that is less costly, more positive in operation, more efiicient and effective, and easier to handle.

These and other objects of the invention will become more apparent from the description given below. The

description together with the appended drawings is a disclosure of one form which the invention may take, and is not intended to be a limitation of the forms and variations which persons skilled in the art may make. For a visual understanding of the invention, reference is made to the accompanying drawings, in which- Fig. 1 is a reduced front elevational view of the basement window embodying the inventive construction.

Fig. 2 is a vertical sectional view on the line 2-2 of Fig. 1, parts being broken away.

Fig. 3 is a horizontal fragmentary sectional view of the ventilator control means substantially on the line 3-3 of Fig. 1.

Fig. 4 is a vertical fragmentary sectional view of the ventilator tilted open in the window frame.

Fig. 5 is a horizontal sectional view taken on the line 5-5 of Fig. 1, parts being broken away.

As shown in Fig. 1, the basement window 10 comprises an outer frame 12, a ventilator 14, and control handles 16 arranged at each side of the ventilator.

Frame 12 comprises a top bar 18, a bottom bar 20, and side bars 22, all of Z-section shape. Tilting stop pins 24 are riveted into the side bars 22 near the bottom thereof. Control handle locking pins 26 are riveted into the side bars 22 substantially above the horizontal center line of the window.

Ventilator 14 consists of a top bar 28 and side bars 30, all of Z-section shape, and a bottom bar 32 of T- section shape. Bottom bar 32 is provided with a vertical section 34 and a horizontal T-stem 36. Tilting pins 38 are riveted into bottom bar T-stem 36 to provide a pivoting means in tilting the window open, and as a pivoting means in locking the window along the frame bottom bar 20. A small secction of T-bar vertical section 34 is coped out at its ends to allow for adequate tilting of the ventilator before it is stopped by pins 24. These latter pins are located above the top edge of frame bottom bar 20 a distance sufiicient to permit the ventilator T-bar 32 to slide out or through in order to remove the ventilator 14 from the frame 12. Insertion of the ventilator is achieved by passing the T-bar 32 back into the frame between the tilting pins 24 and the frame bar 20.

Control handles 16 are arranged to swing in a vertical slot 40 cut in ventilator side bars 30, and pivot on pins 42 fixed in side bars 30. Control handles 16 have a broad flat handle portion 44, a web plate 46, normal to portion 44, through which pivot pin 42 passes, and a cam catch 48 arranged in parallel with but offset from handle portion 44 by the connecting web plate 46.

Control handles 16 are located on pins 42 substantially above the horizontal center line or center of gravity of the ventilator 14 in order that when they are grasped, the ventilator will depend in a vertical fashion, greater control in handling the ventilator in or out of the frame, in tilting the ventilator open, or in closing it tightly in the frame.

Glass lights or panes 50 are sealed in the ventilator framing bars by means of putty 52, about a center T- section divider 54, in accordance with current window practice.

Because of the side control, locking and camming action of the control handles 16, the perimetric contact of the ventilator and the frame is positive and complete. In addition, the camming action of the control handles 16 against locking pins 26 causes the ventilator T-bar 32 to bear firmly down against the frame bottom bar or sill 20, so as to make it substantially weathertight.

Another feature of the construction is that double contact is achieved between the top and side bars of both ventilator and frame, thus making for an excellent weatherproof seal in the window. In Fig. 5, it will be thus giving noted the side bar Z-sections bear against each other at two lines, front and rear, so that a positive double weathering contact is achieved.

In operation, the basement window here described functions by a very simple method. The window frame 12 is fixedly mounted in a window opening, arranged in a cement block, brick or poured concrete wall. The frame should be sealed in place to prevent moisture and air leaks about the frame bars. The ventilator 14 is then put into the frame by passing the bottom bar pins 38 over and down inside past the frame bottom bar 20, at the same time easing ventilator bottom T-bar 32 past tilting stop pins 24 on the frame side bars 22.

To lock the ventilator 14 in place, control handles 16 are pivoted and lifted upwardly so that the cam catches 48 pass under locking pins 26. Handle portions 44 are then pivoted downward to lie flush along ventilator side bars 30, swinging cam catches 48 behind and into firm camming engagement with locking pins 26.

To tilt ventilator 14 open, the control handle portions 44 are pivoted upward, releasing cam catches 48 from pins 26 and the ventilator is tilted outwardly at the top, swinging downward on tilting pins 38 until stop pins 24 engage bottom T-bar 32 and bring the ventilator to rest.

It will be seen from the above that all action and operation of the ventilator 14 takes place after the control handles 16 are grasped by the person operating the window. Such balanced control insures smooth functioning of the window in its installation, opening, closing or removal operations. More efiicient closing is obtained because the window is cam latched above the center line, and there is practically no danger of leaving the window open when the control handles are pushed downward into locking position.

Because the control handle portions 44 are arranged and lie fiat upon the ventilator side bars 30, damage to the handles is substantially eliminated. Also packaging for shipment, and stacking of the units in storage or shipment is considerably improved. These aspects of the invention bring about a substantial reduction in costs.

It will be obvious, of course, that. the construction here disclosed is also applicable to residential, industrial and commercial windows.

Having described my invention in its simplest terms, it is to be understood that the details of the foregoing specification may be changed and varied in greater or lesser degree without departing from the essence of my invention.
