COMBINATION vnnrrrnn'ron Ann CANOPY.
Application fiieana 10,
The present invention relates to improve-- 'ments in a combination ventilator and can opy and its particular object is to provide a built-in'canopy for a kitchen stove or simllar appliances which is constructed'in such a manner as to serve as a ventilator for the entire room. 7
Canopies of this character are used in connection with kitchen stoves at the present time, but they extend downwardly below the v ceiling and leave an airgpocket surrounding the same, which is not subjected to the draft of the canopy. Where the canopy thus depends from the ceiling it'also usually hapv pens that itsouter wall soon becomes unsightly. due to vapors condensing on the same and leaving marks difficult to remove.
In the present invention it is proposed to construct a canopyin such a manner as to be perfectly flush with the ceiling so that the entire room is subjected to the draft of the canopy, there being no air pockets while at the same time the canopy-catches the smoke and vapors rising from the stove;
It should be understood that while my combination ventilator and'canopy has been described principally in connection with a kitchen stove; a similar construction may render useful service inother connections.
i The preferred form of my invention is illustrated in the accompanying drawing in which 1 Figure 1 shows a top plan view of my combination ventilator and canopy. Figure 2 a vertical central section the same. v
Figures 3 and 4 enlarged detail views in section of portions of my device. J While I'have shown only the through preferred i 4.0 7 form of the invention, I wish to have it un- ..derstood that various changes or modifications may. be made within the scope of the claim attached hereto without departing from the spirit of-the invent-ion. j I My canopy 1 is made of sheet metal and 7 preferably consists of four side elements 2 slanting downwardly so as to leave a comparatively smallopening 3 on top and a large opening at the bottom. The lower 1926. semi no) ioaoco.
margin ofthe entire canopy is first turned outwardly as at (5 to present a horizontal flange then turned upon itself-as at 7 until it reaches thebase of the flange 6 so, as to. present a double, thickness of material while 2 its extreme end is bent downwardly as at 8 to form a vertical flange. The canopy is." made of a size-so as to fit at its lower end between two ceiling joists 9 withthe horizontal flange 6. lying against the bottom of the joists so that the entire canopy may so r be secured to the joists by vmeans of a few nails driven through the double flange. The j V vertical flange8 is dimensioned to substan-.
tially correspond to the thickness of the ceil-.
ing which latter usually consists'of laths 11 5 nailed to the joist and plaster 12 secured to the laths and finished in any suitable manner. The lower end of the flange 8 may be curled as shown at '13.
At the neck of the upperend the canopy a i is turned into a vertical flange .141 then turnedupon itself. as at 16 and turned again as at 17 to provide a groove into which may 1 be placed the lower end of a transition piece 18 which latter reduces the opening and al- (5 lows of connection with a cylindrical pipe 19. The corners at which the sides 2 join may be re-enforced by means of ribs21. I
The advantages of my combination ventilator and canopy should be readily understood so from the foregoing description; After the ceiling joists have been laid, the canopy is placed so that its horizontal flange 6 lies.)
against the bottom faces of thejtwojoists as shown in Figure 2 and is secured in place by the introduction of a number of-nails.v
The transition piece is oined and the pipe Y 1 joined to the transition piece. The laths and coat of plaster may then be applied and'j when finished the face of the plaster is substantially flush with the bottom edge of the canopy so that no conden'sationcan deposit;
on the outside of the canopy while at the same time the entire room is subjected to the draft of the canopy, spaces or air pockets. The joints on the in-' side of'the canopy are made so that there is 'no resistance to the flow of gases. The enthere being no draft I tire canopy nlay be made of one sheet of metal and may be pressed into form by a simple operation.
I claim I In combination, parallel ceiling joists of flange to the bottom faces of the joists, and a second flange extending downwardly from the inner margin of the first flange, the second flange serving as an abutment for and being coextensive With a ceiling secured to the bottom of the floor joists.
In testimony whereof I affix-my signature.
