JAMES LABANAUSKAS, or` WAUKEGAN; rumors.V
Avinv'rmn'rI-Nef APPARATUS.
Application'led March 26, 1925. 4Serial No. 18,512.
My invention relates to improvements in ventilating apparatusand has for' one of its objects the production of a device of the kind, Ywhich Vis extremely neat and attrac- Vtivein appearance, simple, convenient, compact, durable, reliable, .eiiicient andsatisfactory for use wherever found applicable. Manyfother objects and Vadvantages of the construction herein shown `and described will be obvious Lto 4those skilled in l.tlnaart from the disclosures her-einggiven.v
filo this end, my invention consists in the novel construction, arrangement and combination of parts herein shown and ldescribed, and more particularly pointed out in the claim.
1n the drawings, wherein like reference characters indicate like or corresponding parts; n
Fig. 1 is a vertical section through the apparatus embodying my invention, the samek being shown installed in the wall of a chimney;
Fig. 2 is a section taken on line 2--2 of Fig. 1; Y
Fig. 3 is a section taken on line 3-3 of Fig. 1; and
Fig. 4 is an enlarged fragmentarysection taken substantially on the same line as Fig. 3.
The apparatus embodyingl my invention is particularly adapted Afor use in dwellings for Ventilating kitchens, halls, basements and the lik-e. For the purposes illustrated, I have shown the apparatus installed in a chimney, but it will'be understood that l am limited to this use only in so far as defined in the appended claim.
Referring to the drawing, the reference character designates a chimney havingV a flue 11. A suitable aperture 12 formed in one wall of the chimney, which wall is also part of a kitchen or the like, is adapted to receive a sleeve 14 of any suitable form and material. In this instance, I have shown the sleeve 14 as cylindrical and have provided it will an inwardly projecting annular flange 15, the purpose of which will presently appear.- Projecting into the sleeve 14 is an annular flange 17 formed integral with a plate 18, which is positioned against the outer side of the apertured wall. The outer side of the plate 18 is also provided with an annular flange 2O in which is pivotally mounted a closure member 22, the closure member 22 being adapted'tforest against the outer edge of the annular flange 2O when it is in its closed position. Pivotally mounted inthe inner end ofthe sleeve 14 is a closnremember 24 which, when in its closed position, will abut the annular flange 15. Pivotally' mounted lupon the innerv surface of the sleeve 14 isa lever .25, one end .of which fis connected byfa llink 27 to the cesure member 24, thelink 27 being .loosely ypivoted inthe lever and .ein .an eye formed upon thevclosure :member 24.
The other end of the lever 25 is lv a rod BOand a relatively flexible strap 82, as shown. One end of the rod 30 is loosely pivoted in the lever 25 and the other end thereof is secured to one end of the strap 32 by means of rivets 33, or the equivalent. The other end of the strap 32 is fastened, as at 34, to an arcuate cam surface 35 formed upon a hinged member 36, whereby the closure member 22 is pivotally mounted in the aforementioned flange 20.
The strap 32 is sufficiently flexible so that when the closure member 22 is brought from the position wherein it is shown in Fi g. 3 to the position wherein it is shown in Figs. 1 and 4, the strap will be wrapped around the arcuate surface 35 in such manner that the lever 25 will be rotated in a clockwise direction (Fig. 1). This' rotation of the lever 25 will cause the link 27 to bring the closure member 24 from the position wherein it is shown in Fig. 3 to th-e position wherein it is shown in Figs. 1 and 4. However, inthe operativeconnected to the closure member 22 by preferred form of my invention, the strap 33 has sufficient rigidity so that when the closure member 22 isbrought into its closed position, the strap will not buckle, but will push the rod 30 to rotate the lever 25 in a counter-clockwise direction (Fig.-1). This rotation of the lever 25 will cause the link 27 to bring the closure member 24 into the position wherein it rests against the annular flange 15.
A fan bar 37a arranged transversely in one en the passage through the sleeve 14 and the plate 18, the same indicating draft through the device. A small electrica-l motor (not shown) may be mounted in the sleeve to drive the fan, if so desired, and provide increased draft.
Any suitable means may be provided for locking the closure members in their closed 37 may be rotatably mounted in a dofpositions. I prefer to provide a pivoted 'latch member 38 upon the closure member 22 adapted to engage a keeper 39 formed in the flange 20. This insures that an undesirable draft through the room may be prevented at any time.
Having thus described my invention it is obvious that various immaterial modifications may be made in the same Without departing from the spirit of my invention; hence I do not Wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned. Y
That I claim as new and desire to secure by Letters Patent is: v
In apparatus of the kind described and in combination, a passage open at its ends, a
closure member for each end of the passage,
means operatively connecting said closure members whereby when one of said members 1s opened the other will be opened, said means comprising a lever mounted in the passage, a link operatively connecting the lever with one of the closure members, a flexible strap operatively connecting 'the lever With the other of the closure members, a cam on said last mentioned closure member, said strap being adapted to be Wrapped about the cam when the closure member upon which it is mounted is opened whereby the lever is actuated to open the other closure member, said strap being sutliciently rigid that when it is univrapped from the cam by shutting of the closure member upon which it is mounted said strap will force the lever in the opposite direction to shut the other closure member.
In testimony whereof I have hereunto signed my name.
