V. S. LUNDEL-l- VENT ILATOR Filed March 1, 1939 Patented Mar. 25, 1941 UNITED, STATES PATENT OFFICE Victor S. Lundell, Jamestown, N. Y.

Application March 1, 19-39, Serial No. 259,185

Claims.

This invention relates to an improvement in ventilators and more particularly to ventilators for installation and use with windows of the swinging or sliding type.

In the disclosed form, the invention is applied to and forms part of a casement window, being interposed between the glass panel and either the upper or lower window rail. The ventilator engages the window rail and provides a seat and securement for one edge of the glass panel.

One of the objects of the invention lies in the provision of a ventilator for application to a swinging or sliding sash.

Another object of the invention lies in the provision of a ventilatorthat may be built into a casement sash or subsequently added thereto upon removal of the glass panel and replacement by one of smaller dimensions.

Another object of the invention lies in the provision of a ventilator for a swinging or sliding sash that provides both inside and outside closure means for the ventilator opening.

Another object of the invention lies in the provision of a ventilator having an exterior closure member which serves as a hood or shield to prevent ingress of the elements.

Another object of the invention lies in the provision of a ventilator having an inside closure that serves to prevent foreign particles from entering the space within the ventilator.

Another object of the invention lies in the provision of a ventilator having a closure member adapted to receive and seat a screen.

Other and further objects and advantages of the invention will be more fully understood from a consideration of the following specification taken in conjunction with the accompanying drawing; and in which- Figure 1 is a perspective view of a casement window in which is embodied one form of the invention;

Figure 8 illustrates the application of the in- 5 vention to a top position in a window.

Reference is now had to the drawing wherein the numeral I0 is employed to generally designate a conventional casement window structure. The window comprises a frame II and sash I2. 10 In cross section the rails of the frame and sash are conventional, as illustrated. In the application of a ventilator, embodying the present invention, to the lower portion of a casement window, said ventilator is designed to rest upon the lower horizontal sash rail I3. This rail includes a horizontal web portion I4, an inner upstanding flange l6, and an outer downwardly directed flange I1. 'Ihe vertical rails N3 of the sash are similar to the rail l3 in cross section.

The ventilator I9 is adapted to be mounted on the rail I3 and comprises relatively fixed and movable members 2| and 22. The fixed member 2|, when adapted for use with a casement window, comprises end blocks 23 having vertical 25 channels 24 located adjacent the inner face thereof. These channels are adapted to receive the inwardly projecting flanges of the side rails l8. The blocks 23 are connected by a hood or shield 26. In the present disclosure the hood is formed with slots 21 adapted to receive screws 28 that have threaded engagement with the upper curved surfaces of the blocks. It is apparent, however, that the blocks and hood may be formed integral by stamping from sheet metal or by casting. The outer faces 29 of the blocks 23 are of a generally circular contour, which contour is followed by the hood 26. The inner edge of the hood terminates in an upstanding flange 3| that is in vertical alignment with the channels 24 and, therefore, with the inwardly directed flange of the upstanding sash rails I8. The blocks 23, in the present form of the invention,

- are each formed with a circular bearing portion 32 that projects inwardly of the ends of the ventilator and is of a diameter less than the width and height of the blocks.

The rotatable member 22 of the ventilator comprises inner' and

outer elements

33 and 34. The inner element includes a curved portion 36 that terminates in a short flange 31 along one edge and a more extensive flange 38 along the other edge. The curved portion 36 of the element 33 is secured to circular plates 39. These plates are positioned adjacent the ends of the

elements

33 and 34, being in close proximity with the bearing portions 32. One or more intermediate plates 39 may be provided, depending on the length of the ventilator. The outer element 34 is formed with a curved portion 4| and terminates along one longitudinal edge in an outwardly directed flange 42. The element 34 is secured to plates 39 substantially diametrically opposite the curved portion 36 of element 33. A ventilating passageway 35 is thus provided. The ends of

elements

33 and 34, projecting beyond the plates 39, provide partial circular recesses into which the end bearings 32 project. Thus, the member 22 is mounted for rotation in the member 2|.

Reference is now had to Figure '1 of the drawing wherein is shown a modification of the structure above described. In this instance, the fixed member 43 includes top and bottom elements 44 and 46. The top element is formed with a hood portion 41 similar to the hood 26 heretofore described. However, the upper portion of the hood 41 is made with a horizontal flange 48 that terminates in an upwardly directed flange 49. The lower element 45 is an angular bar having an upstanding flange that terminates in a laterally offset portion 52. The offset portion 52 overlies the upper edge of flange l6 of the rail l3, being in the same vertical plane therewith. The upper and lower elements of this fixed member are connected by end blocks heretofore described. The rotatable member of this modification comprises

elements

53 and 54. Element 54 is substantially identical with the element 33 heretofore described. Element 54, however, is formed with an upstanding flange 56 that contacts a shoulder formed at the jointure of the hood 41 with flange 48.

It will be noted in the structure of Figure 3 that the rotatable member 22, when in closed position, provides three-surface contact with the fixed member 2|; namely,

flanges

31, 38, and 42. In the modification of Figure '7, however, due to the additional provision of flange 56, four-surface contact is had between the rotatable memher and the fixed member when the ventilator is closed. Furthermore, in the modification, provision of a bottom element 46 may, under certain circumstances, provide better seating for the ventilator'on the horizontal window rail 13.

Attention is now directed to Figure 8 wherein is shown an application of the present invention to the top of a casement window. In this instance, the fixed member 51 includes a hood 58 that terminates adjacent the downwardly directed flange 53 of the upper horizontal rail SI of the sash. The lower element of this member is generally T-shaped and includes upper and lower flanges 62 and 33. The upper flange serves as a stop to limit movement of the rotatable member and the lower flange substitutes for flange 53 in the positioning of a glass panel 64. The rotatable member 66 may be substantially identical with the rotatable members heretofore described.

It is to be particularly noted in the present invention that the rotatable member is comprised of two semi-circular spaced apart elements and that the flanges on these elements serve as stops to limit movement and to constitute a contact seal when the ventilator is closed. Furthermore, the ventilator is closed ext-eriorly as well as interiorly by the provision of two rotatable elements. Thus, neither dirt, nor snow, nor ice can interfere'with the proper functioning of the device. In Figure 4 of the drawing there is shown a section of screening 61. Should it be found necessary to screen a ventilator of this type, a small piece of screening may be cut and inserted into the circular portion of the rotatable member in a curved position and the natural springiness of the screen will hold it in place. It is to be understood that the inner and outer elements of the rotatable member are substantially in balance and, therefore, no spring or latch means is required to maintain the ventilator in either open or closed position. Furthermore, should the ventilator be open and a storm occur, it is conceivable that wind striking the large flange 42 would close the ventilator.

The present invention, as mentioned above, is adaptable for mounting in windows previously installed. The procedure simply involves removing the glass panel, inserting the ventilator in thesash frame, shortening the glass equivalent to the ventilator height, and repositioning said glass.

Although applicant has shown and described only a few of several modifications of the invention and its application to a casement window, it will be understood by those skilled in the art that other modifications or variations of the structure may be made and are contemplated insofar as they are within the spirit and scope of the invention as defined in the hereunto anneXed claims.
