This invention relates to the broad class of vehicle aeration and ventilation and has more particular reference to an improved window and door ventilator expressly designed for installa- 5 time upon present day types of automobiles and motor conveyances.

Admittedly, there is considerable activity in this particular line of endeavor and an apparent need for practicable means for satisfactorily ven- Tiil tilating the interior of automobile bodies, particularly of the so-called closed car type. In fact many automobiles are now being equipped at the time of manufacture with special draft controlling ventilation windows and equivalent devices and accessories.

it follows, therefore, that I have evolved and hiced a simple and economical window venor particularly adapted for use as an attachment to doors and windows of the sliding glass ty More specifically, however, the novelty is p iicated upon a ventilator capable of being installed in conventional or typical door and windew constructio without requiring extensive to us of the existing or stock parts, the ventilator being so made as to utilize the prin ciple of suction produced when the car is in. moti n to effectively extract foul air from the inoi the car and to set up a controlled cir ble 0. providing the requisite venties. .cular construction, features and ad t ll lescription and drawings. ings: l. a fragmentary elevational View the improved ventilator installed in a w opening and associated. with the a or pane.

; a longitudinal or horizontal settaken. on the plane of the line fragmentary fictional later from inner the automobile is denoted by the numeral '7 and the sliding glass window by the numeral 8. The felt or rubber packing is indicated at 9 and this is modified or out slightly at the top to accommodate the improved ventilator. The ventilator itself is preferably of light weight metal. It is made up primarily of two parts,

7 that is a longitudinally elongated attaching or adapter plate 10 and the semi-funnel shaped shield 11. This unit or part 11 may be conveniently referred to as the air evacuating funnel. This is so constructed and arranged as to provide forthe removal of foul air by the now well known suction principle, the suction being produced when the car or automobile is in motion. It will be noted in Figure 6 that the adapter and mounting plate is formed with a plurality of elongated air passage slots 12 of. general rectangular form and tapered at one end.

It will be observed that where the openings or till slots 12 occur the upper and lower edges of the plate are bent to provide retention or keeper flanges l3 and M respectively. These are bent with respect to the "plate 10 to accommodate the companion or attaching flanges 13c and I la carried by the longitudinally elongated or shell like funnel 11. It will be observed that the funnel approximates in length the circulating slot 12 so as to match and cooperate with said slot. Moreover, it will be observed that these flanges 13c and l lo or bent portions are formed inte gral with the tunnel. in other words the funnel fits over the slot 12 and corresponds more or less in shape and proportion thereto and is provided with upper and lower flanges which fit into the retaining flanges 13 and it on the plate. it will be noticed. in Figures 3 and l particularly that the tunnel is tapered that is it is increased gradually in cross sectional proportion, the forward end toward the rear discharge end l5, through which the air e. capes into the atmosphere. The shallow or forward end extends through the pointed end portion 16 of the slot and is provided with a suitably proportioned attaching lip or flange 1'5. This may be suitably seen ed. to the inner face of the adjacent porlLlOl 'S the plate l0. Obviously toe plate may he provided with any number of the slots 12 the companion evacuating units or funnels It. It is evident that by disposing the disends toward therear, that in a di e to the direction'oi movement of requisite suction is produced at end to draw out the air from the interior of the automobile.

It is further clear that the plate 10 is pro portioned so as to fit into the upper portion of the window frame with its end located in the guide groove or channel for the sliding glass window somewhat as shown in Figure 2 and the packing is cut so as to maintain a requisite air tight mounting and joints.

I might also call attention to the combined thickness of the flanges which serve to connect the various parts together. That is to say the thickness of the plates and flanges are such as to space the plate 10 from the window glass 8. In fact to insure more effective spacing the plate is provided on its interior with rubber spacing buttons 18. These buttons allow a slight circulation of air between the glass and the plate 10 to prevent sweating and frosting of the glass. The position of the device in the window however does not interfere with the free movement of the window glass. That is it can be raised and lowered in the usual way for giving signals or can be opened completely to a point below the ventilator and atmospheric conditions demanded. Not only this it will be observed that the glass 8 can be used as a regulator or control for regulating the size of the slot 12 to increase or decrease the ventilating action of the device.

It is evident that there are other various commercial phases and aspects of the application which might well be described but the essential thing that I desire to explain so far as this description is concerned is clearly describe and illustrate the construction and application of the ventilator itself.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size, and rearrangement of details coming within the field of inven es/aces tlon claimed may be resorted to in actual. practice, if desired.

Having thus described my invention, l claim as new is:

i. In a structure of the class described, in combination, a frame, said frame being provided with a guide channel, a sliding glass window in said channel, a plate supported in said channel and spaced clear ofthe glass window to permit unobstructed operation of said window, said plate being provided with air discharge slots and evacuating shields for said slots, said plate being further provided with spacing-buttons cooperable with the glass window to serve as antirrattler elements as well as to facilitate restricted circulation of air between the plate and window for the purposes described.

2. In a structure of the class described, in combination, a frame, said frame being provided with a guide channel, a sliding glass window in said channel, a plate supported in said channel and spaced clear of the glass window to permit unobstructed operation of said window, said plate being provided with air discharge-slots and evacuating shields for said slots, said plate being fun ther provided with spacing buttons cooperable with the glass window to serve as anti-rattler elements as well as to facilitate restricted circulation of air between the plate and window for the purpose described, a ventilator comprising an adaptation and supporting plate provided with a plurality of longitudinally elongated air circulation slots, and complemental funnel like shields or closures for said slots.

3. A ventilator of the class described comprising an adaptation and mounting plate having a slot, said plate being further provided with. spacing buttons cooperable with a glass window in a car door or the like to serve as anti-rattler elements as well as to facilitate restricted circulation of air between the plate and window for the pug poses described.
