VENTILATINQ- WINDOW.

Specification of Letters Patent.

Patented Apr. 11, 1922.

To all whom it My concem Be it known that I, (J'nAnLns R. BOWMAN, a citizen of the United States, residing at- Butler, in the county of Bates and State of Missouri, have invented certain new and useful Improvements in Ventilating lVindows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyng drawings, and to the letters and figures of reference marked thereon,

' which form a part of this specification.

This invention relates to ventilating windows for buildings and the primary object thereof is to provide a window frame adapted to conveniently support normally aligning window pane sections, each of which is capable of being independently tilted about its pivots to provide a ventilating space, thus permitting the window to be opened without. the necessity of employing sash cords or weights.

Another object of the invention is to provide an inexpensive, durable and efficient window frame which is preferably constructed of metal and provided with means for adjust-ably retaining the window pane sections or units in any adjusted position between two extremes, the general organization being such that a tight window may be provided to protect the interior of the building against the elements, and the sections are so mounted that any one or all of them can be tilted from a vertical plane to an inclined plane to permit ventilation, the angle of inclination of the pane sections determining the angle of the stream line of air entering the building.

The novel arrangement of parts and combinations of parts illustrating the preferred embodiment of my invention will be specifically described hereinafter, reference being had to-the accompanying drawings, in

which Fig. 1 is a perspective view of a window frame and its complementary pane units or sections, parts being broken away to show certain elementsin section.

Fig. 2 is a fragmentary, longitudinal, sectional view through the window pane units. Fig. 3 is a transverse sectional view through one of the frame stiles and a pane supporting means, and

Fig. 4 is a detail perspective view of a fragment of one of the stiles of the window frame.

In carrying out my invention I prefer to construct the window frame of metal. The frame is shown as consisting of the stiles or sides 1 and 2, the top rail 3 and the bottom rail 4 to provide a substantially rectangular frame. There are battens or cleats 5 and 6 on the respective rails 3- and 4, against which the top edge of the uppermost pane section Or panel and the lower end of the lowermost pane section or panel may respectively contact so that when all of the panels are in vertical alignment, a tight closure will be provided for the window opening.

Each side bar 1 and 2 is provided with offset portions 7, and with inclined slotted portions 8 and vertically slotted portions 9, there being openings or recesses 10 in each ofi set portion to receive the pins or stop projections 11 on the ends of the yielding actuating levers 12, which are connected to the jaws or clamping beads 13 which constitute supports for the panels 14. The: beads 13 may be in the form of channels with their

free edges

15 and 16 adapted to clamp against the opposite sides of the panels 14, the tension of the

jaws 0r edges

15 and 16 being determined by the nuts 17 on the bolts 18, which also constitute fastening means for securing the flanges 19 of the levers 12 to the beads.

The beads or clamping members are provided with pivot pins or trunnions 20, which are adapted to be received in the slots 9 on the respective vertical side members 1 and 2 so that when the panels or members are in place, they may be swung about the axes of the pivots 20.

The edges of complementary panels or panel units are beveled, as at 21 and 22 (Fig. 2), to effect a closed barrier to wind or rain when the panels are in vertical alignment.

Packing may be utilized if desired along the edges of the panels for the clamping beads so as to afford efficient grips for the

jaws

15 and 16 as well as to eliminate the tendency of the glass to crack, due to expansion and contraction induced by variations in temperature.

If desired, the inclined portions of the longitudinal edges may also be faced with felt, rubber or similar packing material, al-

- all of them may be swun though these may be omitted if found expedient.

Assuming all the parts to be assembled and the panels in vertical alignment, the window opening will be effectually closed. If it is desired to ventilate the building, one or more pairs of arms '12 may be actuated to withdraw the pins 11 from the recesses 1O sothat the panels may be swung about the axes of the pivot members 20, as indicated in Fig. 1, the panels being held at a determined angle by allowing each of the stop projections 11 to enter one of the arcuate row of holes or recesses -10.

If additional ventilation is required, the panel may be swung to a substantially horizontal position or additional panels may be tilted in the manner of the second panel from the top (Fig. 1).- Indeed, substantially all of the panels can be swung to a substantially horizontal plane if desired, or to any angle within-a range of 90. Ordmarily, 45 will be the proper angle and the panels may be so inclined as to direct the incoming air upwardly so as to prevent liability of draught being directed upon the occupants of the room in which the invention happens to be located.

It will be apparent that the device can .be easily constructed, the side bars may be stamped out of sheet metal if desired and the frame fabricated in an appropriate manner.

It will also be apparent that the panels may be'constructed of plate glass with the beads or supporting clamping members at the respective ends extending the entire Width of the glass panel and that the operating layers 12 may be fastened to the beads by the same bolts that provide the necessary clamping tension for the beads. The levers 12, however, may be. otherwise fastened if desired.

When the panel is equipped with its end beads and levers with the trunnions or pivots 20 projecting in opposite directions, it will be apparent that the completed panel unit may then be associated with the frame by guiding the pivots 20 into engagement with the forwardly inclined slots 8 and allowing them to be seated in the bottom.

slots 9 so that the pins 11 will move in the same are as the are formed by the row of recesses or openings 10. The parts are then assembled and it will be only necessar to tilt. the panelsto the proper. angles w ere ditions, the dimensions being immaterial as they may vary in accordance with the requlrements.

Under certain conditions the sides of the frame may be constructed of concrete or artificial stone with the

slots

8 and 9 formed therein and the openings 10 for the window pane panels and their'appurtenances, or the sides may be constructed of wood but I pre fer metal as it most readily adapts itself for the purpose intended.

It is to be understood that the levers 12 are sufficiently yielding so that the stop pins or projections 11 can be retracted from the openings 10 when it is desired to adjust the panels.

What I claim and desire to secure by Letters-Patent is:

1. A window frame having side bars provided with pivot-receiving openings, a transparent panel extending across the frame and having pivots engaging said openings, a lever connected to the panel, having a stop projection, and an oflset portion on one of the side bars having recesses to be engaged by the stop projection whereby the panel may be held in a predetermined inclined position.

2. In combination, a window frame hav-- ing side bars provided with vertical slots merging into inclined slots, panels between the side bars having trunnions in their ends engageable. with the inclined slots to be guided into the vertical slots, and yielding levers connected to the panels stop projections, the side bars having openings for engagement with the projections.

3. In combmation, a window frame comprising vertical side bars having offset portions projecting forwardly of the side bars, the side bars having trunnion-receiving slots and the offset portions having stop-receiving openings, a plurality of panels extending across the frame, edge-engaging beads clamped to the opposite ends of the panels, trunnions carried by said beads and engaging the trunnion-receiving slots, and levers carried by the beads and having stop projections engaging the openings in the offset portions of the side bars.

In testimony whereof I afiix m signature,

CHARLES R. B WMAN.
