G. c. OAKES I VENTILATING DEVICE Fild April 9, 1954 INVENTOR Patented Mar. 17, 1936 TING DEVICE My invention relates to ventilating devices for windows and in its more specific aspect for windows of conveyances, such as automobiles, aeroplanes and other land, air or water conveyances.

It is well known that the air currents flowing along the sides of a car, due to its speed, are bent outwardly at the front corner posts and return into contact with the sides at a point intermediate the front and rear ends of the forward windows. Therefore, if an opening be provided only in the region between the front corner post and said intermediate point, no air will blow from the outside to the interior of the car through said opening but, rather, the inside air will be will result. heretofore been taken to provide for draftless ventilation, by cutting away the forward upper portion of the glass window or the forward lower 20 portion of the top window frame member, the window'when partially raised into initial contact with said member closing the window opening save for said cut away portion, through which draftless ventilation takes place. By raising the window fully the entire window opening is closed.

These expedients, while effective for ventilation, alter the lines of the car body or window structure and are costly to make since in the one the lower side of the top frame member, mate- ,rially narrowing it at that point, and in the other case cutting out a similar recess from the upper front corner of the plate glass window, an expensive operation.

35 My invention contemplates the provision of a similarly located ventilating opening but without the necessity of modifying either the lines of the door frame or of the window, itself, so that the external lines of the fixed parts of the car'body and window remain unchanged. This I accomplish at a greatly reduced cost. Moreover, my device may be quickly, easily and cheaply applied to cars already in use without any modification of their fixed structure,whatever.

4 To these ends my invention contemplates the substitution for the cushioning felt, or other resilient material, in the window seat channel of the top window frame member, of a'cushioning member, conveniently of U-shape in cross sec- 50 tion, preferably of resilient material, such as rubber or the like. Where a U-shaped member is used one or both of its sides are extended a material distance below the lower edge of the top frame member, the extended side or sides 55 being cut away at the forward end or ends, at

drawn out therethrough and draftless ventilation Advantage of this phenomenon has case they involve forming an elongated recess in least to the lower edge of the top frame member, to form a ventilating opening. This member therefore serves the double function of providing a cushioning seat for the window and also an opening for draftless ventilation. The latter ,result is effected by raising the window to the loweredge of the U-shaped member. In this position as well as in the full raised position there is preferably a positive contact between the re-'- silient member and the window top, preventin drafts and rattling or vibration. To further increase the anti-rattlingcharacteristics of my device its extended side or sides may conveniently converge slightly, the inner free lower edges being beveled to permit easy ingress of the window top.

In another aspect my inventioncontemplates the provision of a ventilating strip made of a material that may be easily cut and mounted in ventilating position by the layman without special tools.

A ventilating strip made of rubber or similar material that may be easily cut with ordinary tools answers this purpose. A strip made of rubber and slightly longer than the maximum length required may be easily out 01f with a knife at either or both ends to, adjust both the overall length and that of the ventilating opening to that most appropriate to any particular make of car. Moreover, since its base as well as its side or sides is flexible it may be easily bent into engagement with the curved bottom of the top frame member or the channel therein without cutting or trim-.

ming its base, as would be necessary in the case" of glass or other rigid material. To facilitate mounting, its. base may be further covered with an adhesive of appropriate character, covered by a protective fabric, which can be peeled off when ready for use. After cutting to length, the width of frame channels being substantially uniform in all makes of cars, when the U-shapecl'type of strip is employed it is only necessary toIIremove the protecting fabric and mount the strip by means of its channel on the top of, the glass window in its lowered position. Then by simply raising the window to its extremeupward 'position the strip will be forced into place, the adhesive of Fig. 1.

Fig. 4 is a perspective view of my ventilating strip with a portion of the adhesive protecting fabric separated at one end, and

Fig. 5 is a vertical section of one of the possible modifications of my invention.

Referring to the drawing, there is shown a car body I provided with side door 2 having sideframe members 3 and top window frame member 4, with window channeli in its bottom. In this channel my ventilating strip 6 is conveniently mounted. This strip is shown in Figs. 1-4 as provided with a base 1, two side extensions 8, cut away at their forward ends 9 to provide a ventilating opening, the front side portions l being only deep enough to serve-as cushioning means for the window when fully raised. It is obvious that when made of rubber or similar flexible material the base I, and particularly that portion of it under the shallow sides l0 where the curvature of window top frame channels is greatest, will readily bend into engagement with said channels without the necessity of trimming to a fit. In order to install it is only necessary to cut to length and remove the protecting fabric II from the adhesive l2 and mount the strip in the top frame channel in the manner already described. Of course any other manner of mounting the strip may be employed.

In Fig. the ventilating device is shown as having only one side extended downwardly to effect ventilation the other side 8' being only of sufflcient depth to effect cushioning of the channel in top frame member 4. This and other forms may where found desirable be reinforced by a flexible plate 13 such as thin sheet steel, this being conveniently omitted from the cut away portion 9 to permit easier bending of the forward end of The side extensions 8 are preferably designedzontal ribs or projections l6. By these expedients all chattering and rattling of the window is prevented.

In Fig. 3 is shown the direction of. the air currents when the window is in draftless ventilating position.

It will be understood that changes may be made in the forms disclosed as where, for instance, the door is not provided with an upper window frame but the window when raised has a seat in the top. Here a single cushioning extension located on the inner side of the window and suitably secured to the seat may be employed. Such changes do not depart from the spirit of my invention. It is also obvious that certain features may sometimes be used to advantage without a corresponding use of other features.
