J. VERNON VENTILATOR Filed March 15 1921 enemas May 13, 1e24,
UNETED STATES PATENT OFFICE VENTILATOR.
Application filed March 15, 1921. Serial No. 452,416.
To all whom it may concern Be it known that I, JOHN VERNON, a citizen of the United States, residing at Phila-y delphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Ventilators, of which the following is a specification. 2
One object of my invention is to provide a ventilator of simple and durable construction which will have parts automatically cooperative to regulate the amount of ventilation proportionately to the strength of the wind.
Another object of my invention isto so construct my improved ventilator that it can be readily used in a window and will provide uniform ventilation -at--all times.
These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which Figure 1 is a front elevation of a window ventilator made in accordance with my invention.
Figure 2 is a top plan View of Figure 1,
Figure 3 is an enlarged section taken on the line of Figure 1, 1
Figure 4t is a fragmentary top plan view of certain of the parts shownin Figure3 with the hood removed,
Figure 5 is a perspective view ter-supporting portion of the device shown in Figures 3 and 1,
Figure 6 is a fragmentary elevation showing in full lines the position into which it is necessary to move the automatically operative shutter to connect or disconnect the same,
Figure shutter,
Figure Sis a section taken on the line 88 of Figure 7,
Figure 9 is a front elevation showing another way of making one of the parts of my invention, and
Figure 10 is a section taken on the line 101O of Figure 9.
'Referring to the drawings and particularly to Figures 1 to S inclusive, l1 represents a member which is illustrated in the 7 is an enlarged face viewof the of the shut form of a board which can be used in a window. This board, as shown in Figures 1 and 2, has two of my improved ventilating devices 12 illustrated in combination therewith. Since these devices 12 are similarly constructed I will only describe one in detail and it will be understood that one or any number of these devices can be used in combination with a board or similar member. My improved device 12 includes a tube 13 which provides a passageway Lt transversely through the member 11. The tube 13 is preferably made of a separate piece from the member 11 and fits within a hole 15 which is cut or otherwise formed transversely through the member 11. The tube 13 can be secured to the member 11 in any suitable manner and I have illustrated for this purpose screws 16. The edge 17 of the tube 13 extends at a slant or incline forwardly and upwardly so that the tube 13 at its top 18 projects further from the front surface 19. of the member 11 than at its bottom.20 as clearly shown in Figure 3.
The top of the tube 13 supports an extension 21 which, in Figures 1 to 6 inclusive, is
illustrated as a separate piece from the tube 13 and is secured to the top 18 of the tube by screws 22; said screws passing through slots 23 in the extension 21. The extension 21 overhangs the outermost portion of the edge 17 of the tube 13 and has a transversely extending groove-2+1 in its top surface; said extension forward, of the groove being made comparatively thin and preferably parallel with the adjacent side of the groove to form a lip 25. A shutter 26, as clearly shown in Figures 7 and 8, includes a very thin plate 27 preferably of light weight metal such as aluminum. This plate has a tongue 28 projecting therefrom and below this tongue the plate is of a shape preferably of the same contour as the cross section of the tube 13 taken in the direction of the slant of the edge 17 In the present instance the cross section of the tube 18 is substantially circular and the lower part of the shutter is therefore substantially circular. The tongue 28 has a slot- 29 cut therethrough of a contour similar to that of thelip 25 of the extension 21 so that when the shutter is moved into the posi tion shown in full lines in Figure 6, the shutter can he slipped over the lip and hang and freely swing in the bottom of the groove 24.. The inner surface of the plate 27 of the shutter 26 is prei' crably covered by a coating of soft felt and the position of the groove 24- is such that the shutterw-ill normally hang in a vertical position with thefelt 3O spaced from the edge 17 of the tube 13 the space between the felt and the edge 17' being greater adjacent the bottom of the tube and snutter than at the top.
A hood 31 which is preferably made of metal, such as copper, is secured'to'the sur face 19 of the member 11 and serves as a covering for the tube and shutter .said' hood at its bottom having an opening The hood 31 flares downwardly and adjacent its bottom on its inner surface has a felt pad 33 secured thereto for-abutment under certain conditions with the shutter 26 as shown in dot-and-dash lines in Figure 3. In other words, the shutter 26 can swing until it strikes the pad 33 but it will be noted that it will be impossible for the shutter to become accidentally detached from the extension 21 until the hood 31 is removed from" the member 11 since the hood does not permit the swinging of the shutter-to the extentthat it can be slipped off the lip 25. In other words,
as previously stated, the shutter must be' moved at a greater angle, such for example as shown in Figure 6, before it can be detached from' the extension 21.
The arrangement is such that any gentle breezes occurring outside of the ventilator will cause air to pass upwardly between the shutter and the edge 17 of the tube 13 and will then pass through the passageway 14. However, if the wind becomes stronger and passesupwardly through the opening 32 of the hood, a pressure will be produced on the outside of the shutter and swing the shutter toward the edge 17 and thereby reduce the opening between the shutter and the edge 17 of the tube. As has been found in actual use an exceptionally strong gust of wind will cause the shutter to be swung into contact with the edge 17 and cut off entrance pf air through the passageway until the strength of the wind decreases.
Under certain conditions I have found that upon change of the wind where the device is used in the window of a room or in a building of any character that there is a counter action and instead of air entering throughthe passageway 14 it will pass outwardly tlierethrough and move the shutter into the dot-and-dash line position as shown iii-Figure 3.
By providing the. felt 30 on the shutter 26 and the felt pad 33 on the inner surface of the hood 31, the device is practically noiseless even though the tube 13 and hood 31ers made of metal The device can be I quickly and cheaply manufactured since in of the tube having an extension 21 made integral with the remaining portion of the tube and if desired this tube having the integral part can be stamped out of flat sheet metal bent into form as illustrated. I have indicated the tube in this particular construction by the reference character 13 In all other respects the construction and use of'the tube is similar to that described in connection with the tube 13.
While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to ing a slot formed therein for the reception of said extension and to permit the tongue above said slot to work in the groove.
2. A ventilator including a tube having its front edge slanting upwardly and forwardly, a support for said tube, a hood covering said tube and open at the bottom, and a shutter mounted to freely swing in front of said tube, said shutter normally resting in a vertical position but adapted to freely swing beyond the vertical position in either direction.
3. A ventilator including a board having a hole; a tube fitting within the hole and having a front end slanting upwardly and forwardly; a shutter mounted to freely swing toward and from said end of the tube, said shutter normally resting in a vertical position but adapted to move beyond said vertical position in either direction under wind pressure; and an open bottom downwardly flaring hood covering said tube.
4; A ventilator including a member providing a-passageway and having its front edge slanting upwardly and forwardly, an extension on said member having a groove formed therein and located beyond said edge, a shutter having a portion working in the groove and normally resting in a vertical position, a cushion on one side of said shutter for engagement with said edge, and
a hood in spaced relation with respect to said edge, open at the bottom and provided JOHN VERNON. 5 with a cushion for engagement with the Witnesses:
