VENTILATOR Filed May 14, 1934 INVENTOR Patented June 16, 1936 UNITED STATE PATENT OFFICE.
1 Claim.
This invention relates to ventilators for windows and the like and it has particular reference to ventilators arranged to be disposed in the sash channel of a window of the slide sash type.
The principal object of the invention is to provide a ventilator capable of ready installation and one which will control drafts through the window and will permit of ventilation yet when properly adjusted will exclude rain. The invention is likewise advantageous in that it may be adjusted to prevent a view of the interior of a room, therefore making it unnecessary to lower the window shade which will interfere with free passage of air through the window.
Another object of the invention is to provide a ventilator capable of adjustment as to width so as to render the same adaptable for installation in windows of various widths. Moreover, the adjusting features of the ventilator are such that they are not visible when the invention is installed operatively in a window, consequently, the invention has a pleasing appearance as well as being utilitarian in nature.
Yet another object of the invention is to provide for movement or adjustment of the ventilator relative to its operative position in a window and which adjustment allows the ventilator to be moved into and out of the sash channel of the lower sash of a window and in which position, the sash will be freely moved to open or closed position.
With the foregoing objects as paramount, the invention has particular reference to its salient features of construction and arrangement of parts which will become manifest,as the description proceeds, taken in connection with the accompanying drawing, wherein:
Figure 1 is a, front perspective view of a window ventilator constructed according to the present invention.
Figure 2 is a. fragmentary View of a window frame in vertical section, showing an end elevation of the invention in operative position.
Figure 3 is a view similar to Figure 6 but showing the invention in inoperative position.
Figure 4 is a fragmentary view partly in section on lines 44 on Figure 3.
Figure 5 is a perspective view of one of the end members of the ventilator in detail.
Figure 6 is an end elevation of the ventilator frame with the end member removed.
Figure 7 is a modified form of the end member which is adapted for use especially in windows where it is not desired to move the same outside the operative plane of the lower sash.
Figure 8 is a plan view of Figure 7.
Figure 9 is a fragmentary view of the lower portion of a window showing the invention mounted therein, and
Figure 10 is a fragmentary detail view of one of the slats, showing the manner in which the slats are collectively joined together for common movement.
Continuing with a more detailed description of the invention, a substantially rectangular frame I is provided, the ends of which are provided with internally threaded bosses 2 as shown in Figures 4 and 6. The purpose of these bosses will be explained presently.
A plurality of relatively parallel slats 3 are pivotally arranged within and lengthwise of the frame 1. While the invention is not limited as to the manner in which these slats are mounted, one form of such mounting is shown in Figure 4 which comprises a tube 4 having a slotted end to receive the end of a slat 3. The free end of this tube is internally threaded to receive a screw 5 passing through the end of the frame I. Each of the slats 3 is thus mounted for pivotal movement in the frame I and for the sake ofconven-ience, the slats are joined together for common movement by means of the strip or rod 6 and connected in a manner similar to that shown in Figure 10 to each of the slats. The connec tion shown in Figure 10 is comprised of a pair of projections 1 either integral with or connected to the slat and embracing the rod or strip 6. A pin 8 pivotally connects the projections l to the rod 6.
For the purpose of adjustment to conform the invention to windows of various widths, a pair of end members 9 are provided, one of which is shownin detail in Figure 5. These end members have flanges [0 which overreach the ends of the frame I and are effective in concealing the ends of the slats 3 and likewise prevent ingress of water in case of rain. For the purpose of strengthening the end members and to close a space which would otherwise be open to ingress of moisture, a strip of metal I I is provided both at the top and bottom.
In the preferred embodiment, the end members are provided with grooves l2 which are parallel with the angularly arranged ends of the end members and companion grooves l 3, parallel with the first mentioned grooves l2 and interconnected by a short groove l4. These grooves are made by a suitable die impression and while slots may be substituted, they might lessen the strength of the end pieces and would therefore be of doubtful practicability. To attach the end pieces 9 to the ends of the frame I, screws l5 are inserted through countersunk openings 16 in the end pieces and threaded into the internally threaded bosses 2 in the manner shown in Figure 4. It is apparent that by virtue of this manner of securement, the position of the end members may be adjusted relative to the ends of the frame I by adjusting the screws 15, by using a longer or shorter screw or bolt. By this manner of adjustment, the width of the ventilator may be changed to correspond with the width of a window without any material change in the appearance of the ventilator since the wide flanges ID of the end members 9 normally overlie the ends of the frame I.
In order to install the ventilator in a window, pegs or square headed screws I! are driven in the window casing IS in the rail intermediate the two sash channels. Two of such pegs or screws are provided for each side of the window casing and spaced apart. The ventilator is held initially in such position and advanced so that the pegs I! will be received in the inclined grooves I3 and further advancement of the ventilator will cause the pegs to be received in the short interconnected grooves I 4 and after the ventilator is passed over the sill 19 of the window, the pegs will be received in the upper grooves I 2 and which grooves will permit of movement of the ventilator from the position shown in Figure 2 to that shown in Figure 3 and vice versa. The position shown in Figure 2 is the operative position of the ventilator, it being observed that it lies within the path of movement of the lower sash of the window and which sash may be lowered to rest upon top of the ventilator. Should it be desired to lower the sash to the bottom, it is simply necessary to push the ventilator outward, out of the path of the sash and in which position it remains until it is again moved to operative position for further use. Should it be desired to remove the ventilator, it is simply necessary to reverse the operation of installation.
In Figures 7 and 8 is shown a slightly modified form of end member which may be desirable for use in windows where it may not be pleasing to have the ventilator positioned exteriorly of the lower sash when not in use. The end member 20 is shown as having grooves 2| therein in inclined parallel planes, each having ofisets 22. A substantially U-shaped channel member 23 is affixed along the edge of each end member 20 and the grooves 2! terminate in offset slots 24 in the channel members 23. A suitable peg or other projection, not shown but similar to the peg I! in Figures 2 and 3 is received in each of the grooves 2| and which afford guides and retaining means for the ventilator. Thus, when the ventilator is not in use, it is a simple matter to lift the same to a point where the pegs or projections 10 will be received in the slots 2| and by pulling the ventilator forward, it may be readily removed.
In both, the preferred and the modified form of the invention, a pair of hooks 25 are provided which engage eyes suitably secured to the lower 1;) sash of the window as shown in Figure 9. A protection is afforded the occupants of a house by this arrangement which precludes the possibility of the ventilator being removed by raising the sash from outside the window, thereby gain- 20 ing entrance to a house by way of the window.
Manifestly, the construction shown is capable of some modification and such modification as is considered within the scope of meaning of the appended claim is also considered within the spirit and intent of the invention.
What is claimed is:
In a ventilator for sash windows and the like, the combination comprising a rectangular frame of a depth slightly greater than the thickness of the sash of said window and having spaced slats pivoted to either end thereof on their longitudinal axes whereby to be overlapping when closed, means disposed midway between the ends of said frame to hold said slats for collective movement, a pair of end members conformable to the ends of said frame having flanges of unequal width to conceal the ends of said slats, interiorly threaded bosses carried by the ends of said frame, screws receivable in said bosses for adjustably retaining said and members, said end members having parallel, interconnecting grooves impressed therein at angles relative to their vertical axes, corresponding to the plane of the sill of said window, means carried by the frame of said window and receivable in said grooves for holding said frame to a limited range of movement during adjustment thereof and means for securing said frame to the lower sash of said window.
