Description
Oct. 1 1940. L..M. JONES WINDOW VENTILATOR Filed Oct. 17, 19:58-
Patented Oct. 1, 1940 UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to a window ventilator which can be readily inserted in or removed from a window opening, which is adjustable to fit windows of different widths and which is provided with pivoted slats or louvers capable of being locked in different positions. Window ventilators of this general type are known, and the present invention aims to provide certain detailed improvements by which such devices are rendered simpler in construction and operation and more economical to manufacture, and which are more eflicient in affording ventilation and protection against rain or the like.
The invention is illustrated in the accompanying drawing forming a part hereof, and in which:
Figure l is a vertical elevation showing the inner side of a ventilator involving the present improvements Figure 2 is a transverse section on the line 2-2 of Figure 4;
Figure 3 is a vertical section on the line 3-3 of Figure 1, showing the pivoted louvers in closed position;
Figure 4 is a vertical section similar to Figure 3 showing the louvers in partially open position;
Figure 5 is a partial transverse horizontal section on the line 55 of Figure'l; and
Figure 6 is an enlarged partial vertical section on the line 6-6 of Figure 1. Referring to the accompanying drawing in detail, the various parts of the ventilator are preferably made of relatively thin sheet metal so formed and shaped as to produce a strong and light and relatively rigid structure which can be easily and cheaply manufactured.
As shown in said drawing, the ventilator includes two vertical side members II) which are substantially the same in construction. These members are connected by an upper horizontal member made up of two parts A and B and a lower horizontal member made up of two parts HA and H3. The parts HA and B of the upper horizontal member are so formed and arranged that the former will slide or telescope into the latter. Similarly, the parts 12A and |2B of the lower horizontal member are so formed and arranged that the part I2A will slide or telescope into the part MB. The parts II A and B of the upper member and the parts I2A and I2B of the lower member are rigidly secured to the vertical members II] as by rivets or spot-welding or in any other suitable manner. The vertical and horizontal members form the frame of the ventilator.
A plurality of spaced slats or louvers are arranged between the vertical members IO and each of these slats is composed of two parts or sections I3A and BB which are so shaped and arranged as to slide or telescope into each other and which are provided at their ends with inwardly projecting ears' [3C pivoted at I3D to the vertical members l0. Since the upper and lower members of the ventilator frame as well as the pivoted louvers are extensible, it will be understood that the ventilator as a whole is adjustable horizontally so as to fit windows of different widths.
In forming the vertical members Ill, the metal s bent into the form of a rectangular channel bar which is made of such size as to fit in the inner guideway of a window frame, indicated at W, that is the guideway of the lower or inner window sash. The inner side of each vertical member ID is shaped to provide a transversely extending flange IDA which overlies the space within the channel of the member I0. The outer side of each member I0 is bent outwardly to form a flange 10B and the ends of the louvers are pivotedat [3D to said flanges IllB, as above noted.
Aconnecting bar l4 is arranged in the channel of each member l0 and is pivotally connected to said ears I3C of the louvers. The ears I and the connecting bars I4 are practically concealed behind the transverse flanges IDA of the member I0, which construction adds to the appearance of the ventilator and prevents curtains or draperies from becoming entangled in the pivoted ends of the louvers.
A latch or handle I5 is connected to the inner face of one of the pivoted louvers adjacent the end thereof and this handle extends inwardly adjacent the edge of one of the flanges IDA, above mentioned. This flange is provided with a series of notches 10C into any one of which the handle [5 may be inserted. The handle l5 is so riveted or otherwise pivoted to the louver as to have a limited lateral movement relative to the flange IDA. It will be seen that by grasping the handle l5 and moving it up or down all the louvers through the medium of the connecting bars l4 can be simultaneously opened or closed to any extent desired and then locked in position by inserting the handle into one of the notches HIC.
In order to insure against the entrance of rain or the like when the louvers are closed or slightly open, the overlapping edges thereof are formed as shown in the drawing. The upper edge of each louver is bent outwardly to form a flange I3E and the lower edge thereof is bent inwardly to form a flange I3F. The lower flange I3F of one louver contacts with and overlies the upper flange I3E of the next louver below when the louvers are closed. This makes a very tight Joint between the louvers. Even when the louvers are opened to some extent, the flanges HE and III will under ordinary circumstances shed water in the absence of strong winds, and prevent its passage through the ventilator.
It will be noted particularly in Figure 6 that on the sections 13A of the louvers, the upper flange HE is made plain or flat and the lower flange I3F is made in the form of an open bead or channel. On the sections I3B this arrangement is reversed, that is, the upper flange ISE forms an open bead and the lower flange ISF is made plain or flat. By this arrangement, when the sections [3A and I3B are assembled, the flat flange on one section slides into the open bead on the other section.
The arrangement of the flanges HE and ISF on the pivoted louvers not only serves to produce tight joints between the louvers, but the particular construction of these flanges afiords means by which the sections of the louvers are readily slidable relative to each other, and furthermore, the flanges on the louvers tend to substantially increase the strength of the louvers so that they will resist tendency toward bending.
The parts HA and HE of the upper frame member are arranged to form a seat on which the window sash may rest, and this seat is preferably inclined outwardly to avoid entrance of water at this point. Said parts are also provided with an inner flange HC and an outer flange I ID which are constructed like the flanges on the louvers as above described. The flange IIC cooperates with the window sash to make a tight joint and the flange IID cooperates with the flange I3E at the upper edge of the top louver to produce a tight joint at that point when the louvers are closed. The parts HA and MB of the lower frame member are also provided with upper and lower cooperating flanges I20 and IZD.
It will be apparent from the foregoing construction that the louvers may be easily and readily adjusted to obtain the degree of ventilation desired and then looked in'position. When closed, entrance of rain or the like is prevented, and even when partially open they will protect against rain and at the same time furnish ventilatlon. If any rain is driven inwardly by the wind past the ends of the louvers, it will be caught in the channels of the vertical members I II and will run downwardly to the window sill and escape to the outside without passing through through the ventilator.
The ventilator as constructed will not interfere with the usual outside window screen as indicated at l6 and can therefore be inserted or removed without disturbing the screen.
Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:
A window ventilator having at each end a vertical side member and also having horizontal top and bottom members, said top and bottom members being rigidly secured at each end to the upper and lower ends respectively of said side members, each of said side members having a longitudinal channel on the inner side thereof m and said top member having a flat outwardly inclined top surface forming a seat for a window sash, a plurality of spaced louvers extending between said side members and pivotally connected thereto on the outer side of said channels in the side members, said top and bottom members and said louvers each comprising two parts slidably connected to each other, whereby said side members may be moved toward or from each other to accommodate windows of diiferent widths, each of said louvers having an outwardly bent flange along its upper edge and an inwardly bent flange along its lower edge, said flanges being arranged to engage and overlap corresponding flanges on adjacent louvers whenthe louvers are closed, a connecting bar arranged in each of the channels of said side members and pivotally connected to each of said louvers, the inner side of each of said channels being shaped to form a transversely extending flange, which flanges overlie and conceal said bars and the joints between the same and the ends of said louvers, a handle pivotally connected to one of said louvers and extending inwardly adjacent'to one of said flanges whereby the louvers may be simultaneously operated, and cooperating locking means on said last named flange and said handle for locking the handle and said louvers in any one of a plurality of positions.
