VENTILATR.
rl`his invention relates to ventilators and more particularly to a damper or shutter tev control the passage of air through the ven tilator.
One object of the invention is to providev a shutter which when closed, will completely 'lock the ventilator and prevent air and rainl Yfrom passing downwardly through the same. i
Another object of the invention is to provide the shutter or damper with a mounting which may be securely fastened in the ventilator but easily removedtherefrom if necessary.
Another object of the invention is to cause the shutter to normally remain open but permit it to be easily shut and secured in the closed position The invention is illustrated in the accompanying drawing, wherein,F
Figure l is vertical sectional view through the improved ventilator.
Figure 2 is a transverse sectional view taken through the ventilatorr along the line 2 2 of Figure l.
The ventilator to which l the limproved shutter or ldamper has been shown applied includes the usual tubular body or conduit i whichl may be of any size desired, and is open at its ends. A hood 2 is supported above the upper end of the conduit 1 by a suitable number of brackets 3, which in addition to supporting the hood 2, also support an annular wind baffle 4 serving to prevent wind from blowing into the upper end of the ventilator between the hood and open upper end of the conduit. Under present conditions it is customary to provide a shut-ter 0r damper in a ventilator but they do not fit snugly when closed, and a space Vis left about the damper between its peripheral edgesr ard the walls of the tubular body of the venti lator through which wind and rain may pass. The space referred Vto 'also permits warm air to pass upwardly through the ventilator from a room and makes it difficult to heat the room in cold weather. Y
In order to overcome the objections noted above I have provided .f1 closure for the ventilator which includes 'a sleeve 5 adapted to fit snugly into the conduit l. This sleeve is of less depth removably secured by a suitable number of bolts or other removable fasteners 6. The upper endportion of the sleeve is foldedk inwardly to provide a circumferentially eX- y than the vconduit andis.
tending fiange 7' and tongues lare cut radially from the frange and bent upwardlyto provide bearing ears 8 disposed 1n opposed .rela- "tion to each other diametrically of the sleeve.
At opposite sides of the recesses 9 formed by the tongues'or ears 8 the free side portions of the: flange are bentto form offset'lips l() and 1l disposed respectivelybelow andabove the plane of the flange, as clearly, .shown in Figure 1'. 1
The closure disk i2 carries a pivot rod 13 which extends diametrically across it and is secured by clamping brackets 14 with its end' portions projecting from the disk.v The projected Vend portions of the rod 13 Vfit into openings formed in thebearing ears 8 and pivotally mount the disk with diametrically opposed marginal Aportions of the` disk fitted into the recesses 9.- By an inspection of Figure l, itv .will bessen that when the disk is mounted and in a. closed position it rests uponthe upper face of the lip 10 for approX- imately one-half its circumference and for the remainder of its circumference engages theunder face of the lip '11. Therefore an overlapping engagement is provided be-4 tween the `disk and the two lips and an air and rain tight closure for the ventilator will be provided. A. weight l5 is secured against the under face of the disk to normally retain it in an open position, as indicated by dotted lines in Figure 1, and an actuating line 16 is connected with an eye .17'so that by drawing upon the line the disk may be swung to a closed position, and held shut by tying the line to a nail or other suitable keeper in a room from which the ventilator leads. It will, of course, be obvious that the line eX- tends vdownwardly through the ventilator and must be of suiiicient length to be readily reached by a person in the room. If it is requiredto repair the closure for the Ventiessary repairs made. The sleeve will then be passed upwardly through the ventilator to the proper position and the securing bolts replaced. s
Having thus described the invention, I claim: l i
v1. A conduit, an vannularly extending flange in said conduit having tongues cut therefrom andbent to provide diametrically opposed recesses dividing the flange into Gli llO
eircumferentially extending portions constituting abutnients and having their ends spaced from each other; said abutment portions being offset from the body of the fiange in opposite directions, a closure disk litted into saidreoesses and pivot-ally connected with said tongues for swinging into androut of a closed position, the closure having` Close contacting engagement with the abutment portions of the flangesl when Closed, a Weight yieldably holding said closure open, and an actuating element connected with said olosure and. extending longitudinallyy through said conduit to permit Closing of the Closure against the action of said Weight.
2. A conduit, a sleeve fitting snugly in said conduit, and removably secured therein and having its upper end port-ion bent'in- Wardly to 'forni an annular liange carried by said sleeve dlainetrleally opposed portions of said flange beingcut to provide tongues bent upwardly to torni dianietrically opposed recesses, a Closure disk pivoted to said tongues vand fitting into said recesses,
