JACOB N. COHEN, OF PROVIDENCE, RHODE ISLAND.
. VENTILATOR.
.To all whom it may concern: 1 Be it known that I, JAoon N. Conan, subject of the Czar of Russia, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and ,usefulImprovements in. Ventilators, of which the following is a specification.
My invention relates to ventilators, and more particularly to the damper and to operating .parts thereof.
' e purposes of my invention are primarily to guide and discharge from the interior of the ventilator the water entering the ventilator and the moisture accumulating upon the damper and other parts by reason of condensation; also to facilitate and render more certaln the action of the' damper itself; and to attain the above ends by a simple and inexpensive mechanism.
To the enumerated ends essentially my in- I 'ventionconsists in such novel parts and in A is a hollow rectangular base-having a circular openlng, a, in its top bounded an inwardly directed upwardly inclined ..an-.
nular flange a. Fixed to or integral wiith the top of the base is a cylindrical casing B provided at its bottom margin with openings b in alinement with flangea. The
flange and the casing wall combine to form an internal trough or gutter C. Upon the casing is mounted the cowlm'em-ber D with the usual vane 03. The means for mounting the cowl may be of any preferred or usual construction comprising the usual vertical pivot rod E connected by a joint c with diametrically disposed braces F fixed to the casing, and with a vertical rod G connected by a joint 9 to a horizontal brace H.
Transversely' of the casing at one side of its center is a pintle I fixed to the casing by nuts i or otherwise Pivotally mounted upon the pintle is acircular damper plate J,
provided with a series of straight paralleh specification of Letters Patent. Application filed November 11,;1911. Serial Not 659,704.

wardly direct ed'marginal flange j nearly, in contact with the casing wall. A strap 7' fixed twthebottom of the plate J loosely re-' celves the plntle I and forms'a journal therefor. In the casing wall at a point not lower than the 'pintle is an inwardly directed stop or lug K upon which rests the edge of the flange j. Fixed to the plate J I K is a vertically disposed clasp L. In detail this clasp is bent up from resilient wire having its ends passing-through openings 1 1n the plate J and clamped tightly thereto near the stop by loops .Z, whence the material is bent to fdrm, two interspaced vertical loops l": and g n intermedlate downwardly directed. loop loop is retracted relatively to the closed or lower portion thereof. In one of the braces F above the plate J is fixed a downwa'rdly' directed pin I Y N ezir the member L on the plate J is fixed the upper end of a chain N to whose lower end is attached a weighted handle 0. Since the damper plate J is pivoted at one side of The opening Z ofthe last mentionedv its center it is evident that the weight of one portion 17 of the plate will be greater than the other portion of the plate 79. The weight of the portion p to which the chain N is attached is, together with the handle 0, in excess of the Weight of the portion p.
Therefore the flange j is normally held down upon the stop K; but when the handle 0 is manually lifted the weight of the portion 2 vis suflicient to force the plate J into a vertical. position as shown in broken lines in Fig. 1, whereby the pin M, whichis of greater diameter than the width of the-loop opening 1*, is forced into the loop I where it is held against accidental escape by-the resilient loops Z The described balancing of the damper parts makes its operation possible with very little exertion on the part of the manipulator. The height of the member K and the depth of the flange p relatively to the plane of the pintle I causes the damper plate J when in normal or closed position to be inclined.
The corrugations upon the plate J together with its inclination induces a certain delivery of all moisture accumulated upon both the top and bottom of the plate J. This collected liquid is precipitated into the gflltter C whence it percolates through the openings 6 to the exterior of the'base A onto the roof, so that no precipitation of moisthe casing, a stop member fixed in the casing in the, plane of the pintle, a damper plate upon the pintle, a downwardly directed marginal :fiarige upon the plate 'orma'lly resting upon the stop member, and agutter in the casing below the flange.
3. In a ventilator, the combination with a casing provided with openings near its bottom, of an upturned internal flange upon the perimeter of the casing adjacent the openings, 21 pintle mounted in the casing above the flange and transversely of the casing, adamper plate upon the pintle, a
stop member fixed in the casing, and a flange upon the damper plate resting upon the' stop member and overhanging the first mentioned flange.
4. In a ventilator, the combination with upon the stop member, a chain attached to the plateadjacent the stop member, a
weighted handle upon the chain, and a catch upon the plate near the stop member Ic'om prising two interspaced resilientloops, and a pin in the brace in the pathv of the-loops of greater diameter than the space between 1:
the loops.
In testimony whereof I have affixed my' signature in presence offtwo Witnesses. JACOB N. COHEN.
