VENTILATOR Filed April 5. 1929 A TTORNE Y.
Patented Jan. 13, 1931 PATENT OFFICE l TETER CHINIEWIGZ, or `DETROIT, MICHIGAN vENTILAToR Application led April 5, 1929. Serial No.V 352,629.
This invention relates to improvements in ventilators and refers more particularly to wall ventilators, and aims, among other things to provide one which is simple and relatively cheap to manufacture,'and which may be installed either in a building already completed at comparatively slight expense or during actual building.
Another object of the invention is to provide a ventilator having means therein for preventing dust and dirt from passing through.
A further object of the invention isto so divert air passing through the ventilatori that it is practically impossible for a strong blast of air to pass through it; and to provide means for opening and closing it that it may be operated by pulling one or other of two cords that depend therefrom. j
Vith these and other objects and advantages in view which will become apparent as the specification proceeds, the invention, which consists in certain novel construction and combination of parts, is hereinafter more fully described with the aid ofthe accompanying drawings, in which:
Figure 1 illustrates a sectional elevation thereof.
Figure 2 is a partial front elevation.
Figure 3 is a section on the line 3-3'of Figure 1.
Figure 4 is an inverted plan view' of the outer end of the air duct.
Figure 5 is a section on the line 5 5 of Figure 1, and
Figure 6 is a section on the line 6-6Yof Figure 3. Y
Referring to the drawings, 1 designates the outer wall of a building, 2 woodworkv therein, 3 joists, and 4; the inner wall of a building. Y
5 indicates the ventilator casing which is adapted to be set in the woodwork 2 between two adjacent joists 3. On the front of the casing is a cover 6 having a central V,opening 7 therethrough. Over'this opening screening 8 is arranged which may be held in position as by an ornamental support 9, so that air Amay pass freely through the cover 6. c
spring 13.v
Pivotally mounted on the inner side of the cover 6 is a disc 10 oflarger diameter than the opening 7 so that when thesaid disc is in vertical position air cannot pass through the opening to'or from the casing 5. A bracket 55' l1 is also secured to the inner side of the cover 6 and has a central rearwardly projecting portion 11a. On the inner side of the disc 10, usually substantially centrally thereof, an eye 12 is arranged. 13 denotes a spring havu,` ing one end attached to the eye 12 and its opposite end fastened to the central portion 11a of the bracket 11. It will be noted that the eye 12 andthe said central portion 11a are relatively sopositioned that the spring 13 al- 55 waystends to move the disc 10 into the open position indicated atlOa in Figure 1, when the lower end of the cover rests against'the back of the casing 5.
To the disc 10 adjacent its lower margin, 70 that is the margin remote from its pivoted portion, a ycord 14 is secured, and on cover 6 a spring actuated latchl is positioned so that its latch bolt 15a is adapted to engage the lower margin of the said disc. The latch bolt 15a is bevelled at its outer extremitylb so that when the disc contacts with itwhen Y moving into closed positionwhich is accomplish'ed by pulling the cord 14, thelatch bolt moves inwards against the Vtension "of its spring 16 and allows the margin of the disc to pass. To the latch bolt 15a a second cord 17 is attached, when the latter is pulled the bolt'moves and allows the disc to be swung into open position indicated at' 10a by the Extending outwards from the casing 5 through the outer wall 1 isv an airyduct 18v which is preferably positioned opposite Vor above (the upper end Vof the disc 10. This duct has an aperture 19 in the outer end of its underside. The bottom of the duct adjaf centthe 'aperture is provided with flexible tongues 2O which engage the lower margin ofy a screen 2l theupper margin of whichA latter rest-s against the vertical'end wall of the duct. In this way the screen is made readily 'removable for cleaning purposes. Within the duct 18 a longitudinal partition 22 may also be provided slidable in slotted 100 rivets 23. In this manner incoming and outgoing air passages 24 and 25 are lformed.
26 and 27 denote eyelets through the cover 6 for the passage of the cords 14 and 17 respectively.
Vhen the disc 10 is in open position air may circulate aroundY its margin into or from the casing and through the duct, 18 but owing to the position of the duct relative to the disc it is almost impossible for an unpleasantly strong How of air to enter through the ventilator. Moreover the provision of the two screens 8 and 21 prevent large particles to pass through theventilator with the. air.
lVhile' inthe foregoing the preferred ernbodiment ot', the invention has been described and shown',`it is understood that the const-ruction is susceptible to such alterations and modifications as tall Within the scope of the appended claims. i n
TWhat I claim as my invention and desire to secure by Letters Patent is:
1. A ventilator comprising a casing having acover withan opening therethrough, a duct extending at right angles to said casing having an aperture towards its outer extremity,
a lshutter pivotally mounted in said casingl adapted to close said cover opening, means tending to hold said shutter in open position, a latch on said cover to hold said shutter in closed position, a 'cord attached to said shutterand extending through said cover by pulling which said shutter is moved into closed position, and a second cord attached to said latch and extending Vthrough said cover by pulling which the latch releases said shutter so that it may be moved into open position by said shutter opening` means.
2. lA ventilator comprising a casing having an opening therethrough, a shutter pivotal in said casing adapted to close said opening, an air duct having an aperture towards its outer extremity extending from said casing, said duct being so positioned relative 'to the casing openlng and the shutter that air` must ypass around the margin of the latter when travelling between said duct and said opening, a. spring mounted on said casing and connected to said shutter to move the latter in one direction, other means for moving said shutter in the other direction, and means for holding the shutter in such position that the spring remains intension.
31A ventilator comprising a casing having a cover with an opening therethrough, a shutter pivotally mounted in saidV casing adapted to-close said Cover opening, an air duct having an aperturetowards its outer extremity extending Afrom Vsaid casing, said duct being so positioned relativeto said casing and its shutter that air must Dass around the margin of the latter when travelling from said duct to'sajid cover opening, a spring actuated latch on said cover adapted to engage the margin of said shutter, means for releasing said latch, means for tending to move said shutter into open position, and means for moving said shutter into closed position. 4. A ventilator comprising a casing, a cover having an opening therethrough, a shutter pivotallymounted in said rcasing adapted to fclose spaidcover opening, an air duct extending substantially at right angles from said casing having an aperture towards its outer extremity,` a longitudinal removable partition in said duct, an inwardly removable screen in said duct adjacent said aperture, a spring actuated latch on said cover adapted to hold said shutter in closed position, means tending to open said shutter and hold it in open position, means for moving saidshutter into closed position from outside said casing, and means outside said casing for releasing said latchand rendering said shutter opening means operative,
