Application September 2, 1931. Serial No. 560,700 3 claims. (ci. 24o- 7.1)l
This invention relates to ventilator-lanterns and more particularly to unitary means which serve both as lights and ventilators for automobiles, omnibuses, ships, airplanes, airships, street cars, railway vehicles, and in any case where a lamp is exposed to gaseous currents. i
My combined ventilator and lighting means considerably reduces wind resistance that exists when separate Ventilating and lighting means are used. There results a lessening in power consumption and cost of fuel. My device is compact and adds to the beauty of design. Itis also less expensive to manufacture than separate units for lighting and Ventilating.
The present invention comprises a combination of means for housing a lamp in an air passage and a light transmitting means adjacent one end of the passage whereby a suction is created by 'air currents impinging on thelight transmitting means. 'The light transmitting means may include any transparent or translucent material adapted to be rigidly placed at or adjacent the said end of the passage, and the lamp is preferably so placed in the passage that the light rays pass or arel projected directly through the light transmitting means.
One end of the air passage is connected to the chamber or enclosur'e to be ventilated and .the other end is provided with the above light transmitting means. This latter end is preferably placed so that the light transmitting means serves to bring about suction of the air from the chamber or enclosure through the air passage.
Various modifications of my device are shown in the accompanying drawings, in which Figure 1 is a side elevational view ofvone form of my device;
1 Fig. 2 is a front elevational view of the device shown in Fig. 1;
Fig. 3 is a vertical cross-sectional view on the line 3-3 of Fig. 2;
Fig. 4 is a cross-sectional View on line 4-4v of Fig. 3;
Fig. 5 is a cross-sectional view of another form of mydevice which view is taken on line 5-5 of Fig. 6;`
Fig. 6 is a front elevational view of Ithe form shown vin Fig. 5; i
Fig. 7 is a plan view of a portion of the device shown in Fig. 5;
Fig. 8 is a vertical cross-sectional view of still another form of my device which view is taken on line 8-8 of Fig. 9;
Fig. 9` is a front elevational view of the form 55 shown in Fig. 8; and
Fig. 10 is a side elevational view partly in cross section showing a modeof attaching my device.
The modification shown in Figs. 1 to 4, com prises a tubular member 1, a casing 2 connected to one end 3 of the tubular member l, and a light transmitting means or lens 4. The other end 5 of the tubular member 1 is adapted to be connected to a chamber or enclosure to be ventilated. The casing 2 is shaped tohouse the lamp 6 and forms with the tube 1 a continuous passage for air, said tube 1 serving as a support for the device. The lamp 6 may-be mounted anywhere in the casing 2 and the lens 4 is placed across the opening 'l of the casing 2. The lens 4 is mounted adjacent, the opening 7 by means of spaced supports 8 so that airV may pass through the spaces 9. The diameter of the lens 4 including the supporting structure l0 extending around the edge of the lens, is greater than the diameter of the opening '7 of the casing 2. The lens 4 is so placed that the axis thereof passes through the center of the opening 7 and at right angles to the plane oil the opening.
- When the above described form is in use, the wind blows against the lens 4 and assumes approximately the path shown by the full lines 1l. The wind current upon passing over the edge of the lens structurecreates a low pressure region in back of the lens 4 at the spaces 9 and along the casing 2 whereby suction is created at the opening '7 and gases are withdrawn through the tube 1 and the casing 2 from the enclosure to which the tube 1 is connected a-t the open end 5. The current of gas Withdrawn yfrom the enclosure is indicated by the dashed lines 12. The light rays y passing through the lens 4 are indicated by dotted lines 13. The casing is so shaped as to produce a stream-,line effect and to prevent wind from disturbing the low pressure region and from entering thev low pressure region.v The tube or support l.' is also preferably shaped to produce stream-line effect and its cross section may be formed as shown in Fig. 4. i
The modification shown in Figs. 5-7 comprises a tubular member 14 which corresponds to the tubular memberv 1 of the modification described above, and a casing l5 connected to one end 16 of the tubular member 14. The other end 17 of the tubular member 14 is adapted to be connected to the enclosure from which air is to be Withdrawn. The casing 15 is of the same general shape as the casing 2 shown in the first modification and is provided with an opening 18 in which is mounted a lamp casing 19. The inner surface of the lamp casing serves as a reflector for light rays fromthe lamp 20.' The lamp'casing 19 is spaced from the inner surface of the casing 15 and is held in position by spacing means 21 so as to form an annular opening 22 for the passage of air.
' Supported by the casing 19 and placed in front of the lamp 20 is a lens 23. The lens andthe structure which supports its edge may be so shaped and is of such size that it serves to deect the wind so as to create a low pressure region in back of the lens at the opening 18 and along the casing 15. For this purpose the supporting structure for the lens 23 may comprise an annular member 24. Any suitable well known means may be used to attach the lens to the member 24.
In the application of the modication shown in Fig. 5, the wind current upon impinging against the lensl 23 and the annular member 24, assumes approximately the paths shown by the 'full lines 25. The 'gases exhausted from the enclosure to which the end 17 of the tube 14 is connected assume approximately the paths shown by the dashed lines 26. The rays are indicated by the dotted lines 27.
Various means may be employed to prevent the entrance of snow or rain into the enclosure to which my ventilator-lanterns are connected. Means are provided in the casing 15, for example, for the purpose of deecting water and to prevent its passage into the tubular member 14. One
form of such delecting means combined with means for defiecting air currents is shown in crosssection in Fig. 5 and a top view thereof is shown in Fig. 7 indicated by the numeral 28. The crosssection of the means 28 in Fig. 5 is taken on line 5-5'.of Fig. 7 which corresponds to line 5 5 of Fig. 6.` This means 28 comprises a metal sheet 29 spaced from the outer surface of the casing 19 and bent so as to guide the water which may enter the opening 18, particularly Ithe upper portions thereof, between the outer surface of the casing 19and the sheet 29. The lower edge of the sheet 29 is extended forwardly so that it conducts the water past the upper end 16 of the tube 14.
For the purpose of defiecting air currents, coming up through the tube 14, sheets 30 and 31 may be attached to the sheet 29. Rod 32 is provided for focussing the lamp 20, and this rod may pass through the sheets 29 and 31 through the openings 33 and 34 respectively.
The modification shown in Figs. 8 and 9 comprises a tubular member 35 and a casing 36 to which the tubular member 35 is connected. The casing 36 is of parabolic or conoidal shape, and enclosing the open end thereof is a lens 37. Slots are provided in the casing in regions where low pressure areas exist when wind impinges on the lens 37. For this purpose slots 38 and 39 are provided in the portion of the casing 36 which portion lies in front of the forward portion 40 of the tube 35 and in back of the lens 37. Any number of slots may be provided and if desired slot 38 may be omitted. L
A parabolic or conoidal Acasing 41 is provided within the casing 36 for housing the lamp 42. Means 43 for deflecting water which may happen to enter the casing 36 through the slot 38 and for deflecting gases coming up through the tube 35, may be provided, similar to means 28 in Fig. 7.
In all of the modications electric current may be fed to the lamps by means of suitable wiring which, as shown, may pass through the supporting tubular members connecting the device to the enclosure to be ventilated.
In Fig. 10 my device, indicated by the numeral 44 is shown connected by-the tubular support 45 Vbe entirely enclosed so that the reflector means to piping 46 which may be led to and connected to a chamber to be ventilated or evacuated. For use on automobiles, for instance, my device may be attached anywhere for example on the hood or front end and the piping 46 may be led to the rear and open into the passenger compartment at any convenient place. The suction produced by Wind impinging on the lens is sufficient to withdraw air from the compartment. A
The suction effect produced may be variedby varying the shape of-the lens. Concave lenses as shown in Figs. 1 and 5 are particularly adapted to be applied to my device where it is used on relatively slower movingvehicles or transportation means. Convex lenses as shown in Fig. 8 are useful in cases where my device is applied to high speed transportation means. Flat-surfaced light transmitting means may be used in some cases.
As shown in certain instances the lamp may is not contacted by the gase's drawn through the device. In some instances a reflector may be omitted.
It is thought that the invention and many of its attendant advantages will be understood from the foregoing description and drawings, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the forms hereinbefore being merely the preferred embodiments thereof.
