wherein the fi UNITED STATES WILLIAM F. WARDEN, OF AKRON, OHIO.
PATENT onnron. l
VENTILATOR.
To all whom it may concern:
Be it known that I, WILLIAM F. WARDEN, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented a certain new and useful lm rovement in Ventilators, of which the fol owing is a full, clear, and exactdescription, reference being had to the accompanying drawings.
This invention relates to ventilators of the type disclosed in Patent No. 677,512, issued Ju y 2, 1901, wherein a sliding damper is employed in conjunction with the air shaft to vary the size of the air port. In using ventilators in Weave sheds, it is necessary to maintain the temperature substantially constant and relatively high. Ventilators as ordinarily constructed are ineflicient, particularly in cold and windy weather, as it is practically Impossible to prevent someileakage through such dampers at all times and especially at Such times as the winds are high. It is also impossible in such ventilators to maintain, in cold weather, the temperaturewhich is necessary in the operation of such sheds, which temperature s ould not vary between the limits of 80 and 85 degrees Fahrenheit. A further serious difliculty in the employment of ventilators with such sheds has arisen from the condensation which takes place on the air shaft and which, dropping down into the building, ruins the fine machinery and the goods in process of manufacture.
It is the ob ect of this invention to provide a ventilator which, when occasion may require, ma be closed toprevent the escape of air theret rough but which, in warm weather, can be operated for ventilating purposes. 1
A furt erobject of the invention is to provide aventilator which will ositively prevent the discharge of water of condensation therefrom.
Generally speaking, the invention may be described as consisting of the combinations of elements embodied in the claims hereto.
annexed and illustrated 'in the. drawing,
re illustrates a vertical sectional view ta en through a ventilator. constructed in accordance with m invention,
.showing the same applied to t e roof of a shed or other building.
Describing the parts b reference numerals, 1 re resents t e air s aft-of my ventila Per end thereof with a downwardly incline deflector 2.
Specification of Letters Patent. Application filed April 25,
Patented June 15, 1909.
1908. Serial No. 429,110.
' by means of a hood 3, the lower end of which is of greater diameter than the" air shaft, whereby it overhangs said shaft and provides a deflector at the top of the air port. The hood 3,is su ported from the air shaft by means of a p urality of'light metallic frames 4, the lower ends whereof are connected to the top of the air shaft. The upper ends of the frame support the hood, as y means of rivets 5. Each frame comprises an inner vertical member, an outer vertical member, a downwardly inclined member, and a substantially horizontal member. The hood is secured to the inclined members of the frames while the outer sleeve 6, which surrounds and incloses the air port, is secured to the outer vertical members of the frames. 7 denotes anintermediate deflector simila to deflector 2, which is secured to the inner vertical member of each frame, as by means of rivets.
Within the air shaft 1, there is mounted a sliding damper 8. This damper is preferably fitted within the air shaft and is provided at its upper end with an outwardly projecting ledge 9 which engages the top of the shaft when the damper is lowered and su orts the damper in its lowered position. e outer end of flange 9 is rounded inwardly, as shown at 10, the diameter of such flange being such outer ends riveted orotherwise suitably se cured to the damper.
with t e cross bars 11 and the lower end whereof is pivotally connected to a bottom damper 13.
drawing, the bottom of the air shaft is bevelefi or inclined, being shown as substana y other uilding in which the ventilator may lid-shaped body having an upstanding flange shaft. The dam or is pivoted to the air The top of the air shaft is covered that the damper may be raised and'lowered For this purpose of so 0 erating said damper, I rovide a link 12, t e up er end whereof is pivotally connected 15 adapted to fitover the bottom of the air engaging the cross bars 11 at their points of intersection, said cross bars having. the1r As will be noted from an inspection of the i parallel with the roof 14 of the shed or be installed. The damper 13 comprises a shaft above the ottom thereof, the pivot close point to 1prevent leakage.
, vided wit being located above the lowest portion of the i This pivot of which there is attached a rope or cord 19 which may be led over-a pulley 20 for the purpose of raising and lowering dampers 8 and 13 together.
-' 21 denotes a clip or similar securing meansfor the rope or cord 19.
The flange 15 will be given such an inclination with respect to the bottom of the damper 13 as to enable it to fit more or less ythe lower end of the air shaft.
For the purpose of preventing the moisture produced by the condensation on and within the air shaft from entering the'shed or other building to which the ventilator may be applied, I provide the following construction:22 denotes a troughwhich is secured to the inner wall of the air shaft, said trough being inclined. As illustrated, the inclination of the trough corresponds to the inclination of the roof 14, the trough being located slightly above said roof. This trough is preferably of sheet metal and may be secured to the air shaft by riveting. The air shaft 1 is provided with an a erture 23 corresponding to the lowest ortion of trough 32 and with a spout 24, whereby any water of condensation that may collect within said trough may be discharged onto the roof of the shed, flashing 25 being provided at this This trough will collect a water of condensation that may accumulate within the interior of the air shaft thereabove and deliver the same onto the roof. W ater of condensation that ma form within said shaft below said trough will be largely collected within the damper 13 r and such water, together with such water of condensation asmay collect on the exterior of the air shaft that is within the building and such water as may'collect on the outside of damper 13'will be discharged into the drip pan 26, which is located below the ventllator. This drip pan may be suspended from the roof or ceiling of the building by means of straps 27 and will be provided with an outlet pipe '28 which will discharge the condensation at any desired point.
From the foregoing description, the operation of my invention wil be clear.
means of rope or cord '19, the dam ers 8 and, 13 may be operated simultaneous y to produce more or less circulation through the air shaft. The parts will, of course, be so pro-- portioned that, when the top of damper 8 en-' ,gages the hood 3, closing the air port,
dam er 13 will be in close engagement with the ottom of the air shaft.
a lug or arm 18, .to the outer end a said port, a damper adapted to close the bot- Vihen it is necessary that there shall be no circulationthrough the ventilator in order to maintain the temperature within the shed or building at the requisite degree, my ventilator may be so closed as to prevent such circulation. hen desirable to ventilate, the two dampers may be operated as conveniently as a single damper, and the ventilator will operate in the usual manner. Furthermore, any objection to the discharge of the water of condensation within the building or shed will be effectively overcome by my construction.
