BRO April l SELF LOCKING VENT Filed Nov. 6. 1956 glwvcnfm Clare/nceEBfo wn y5o v of a stationary section 8 and removable section UNITED STATES PATENTGIFFIC- i Patented Apr. 12, 1938 Y Y SELF-LOCKING VENT y Clarence Brown, Bentonl Harbon, Mich. f Y Application November 6, 1936, serie1.Ne. 109,600
This invention relates to ventilators and more particularly to roof ventilators. Y
The primary object of this invention resides in the yprovision of a leak-proof roof ventilator havinga removable self-locking section or cap there- Another object of this invention resides in the provision of a roof or smoke pipe ventilator consisting of an embodiment of elements secured tgether against leakage without the use of solder or other similar fluxing material. e
A further object of this invention resides in th provision of a roof or othersimilar type ventilator having a particularly constructed stationary y section adapted to accommodate a removable section or cap.
A still further 'object of this invention resides in the provision of a roof ventilator consisting of a stationary section and cap adapted to be revmovably assembled thereon so as to prevent rattling therebetween. l
, Aside from the aforesaid objects this invention resides in the provision of a roof ventilator consisting of a stationary and removable section or Acap held together by locking means adapted to v bindingly retain the sections against displacement andin rigid relation to one another.
With these and other objects in view this invention resides in certain novel features of construction and arrangement of elements to be vherein- "after more particularly described in the specifica- I the ventilator approximately on line 3-3 of Fig. 2.
In the present illustration of this invention the i' numeral 5 designates, in general, a roof or other similar type ventilator which preferably consists or cap 8.
The stationary section 8 consists of a suitably shaped base plate 6 having an openingl'l therein to the wall of which is connected as by flanges I I,
(01.. asl-.66).
formed on the lower endsoi outer .and inner;y
v 'I'he outer sleeve 9 is provided With an outwardly projecting annular bead I 2 adjacent its upper end, while secured to the outer surface of the sleeve, in the region of the bead and in circumferential spaced relation, are substantially resilient clamps I3 adapted to engage tangently disposed flanges I5 formed on the lower end of a removable sleeve I4 which supports a hood I6 and skirt I1 therefrom through the instrumentality of suitable brackets I8 rigidly connected thereto as by rivets or the like. While the sleeves 9 and II! are herein recited as an adjunct to the base plate 6 to form a roof ventilator it is within the purview of this invention to soconstruct the exit end of a smoke pipe for removable attachment of the cap 8' thereto.
In order to permit the'clamps to readily align with the flanges I5 when assembling the removable and stationary sections, the flanges are gradually reduced in Vwidth at one of their extremities as at I5' and, upon disposing the clamps in alignmentY with the flanges at said reduced portions, the flanges will pass beneath the clamps upon rotating the removable section in the proper direction, thus causing the sleeve I4 to be tightened against the bead as the higher portions of the anges slide beneath the clamps.
Although the removable section may be connected to the stationary section as heretofore stated, it is withinr the purview of this invention to snap the flanges I5 beneath the clamps and With this invention fully set forth it is apparent Y a leak-proof roof ventilator is provided'without soldering the joints of the various elements thereof and, through the instrumentality of the selflocking elements, the removable section can be easily connected tothe stationary section and turned until tightened. y
Having thus described my invention what'I claim and desire to protect by Letters Patent is:
1. In a, ventilator of the character set forth the combination of, a base plate having an opening thereininner and outer sleeves secured to the base plate in registration with the opening there- Y 1n, an annular bead on the outer of said sleeves,
sleeve in the region of the bead, a removable Sleeve telescopically connected to the free end ,of the aforesaid sleeves, tangently disposed flanges formed on the removable sleeve for engagement by the clamps, a hood over the removable sleeve, a skirt surrounding the upper portion of the removable sleeve in spaced relation therewith, and brackets secured to the removable sleeve and supporting the hood and skirt in spaced relation to one another.
2. In a Ventilator of the character set forth the combination of, a base plate having an opening therein,V a tubular section secured tothe base plate in registration with the opening` therein, an annular bead on the tubular section adjacent its outer end, resilient clamps secured tothe:
tubular section with their free ends deected outwardly and overlying the annular bead, a re-v movable sleeve telescopically connected toY the free end of theV tubular section; means on the peripherally spaced clamps secured to the outer removable sleeve engaged by the resilient clamps for seating the inner end thereof against the annular bead Yoi" the tubular section, and a hood Y carried by the removable sleeve in spaced relation thereto. c
3. In a Ventilator of the character set forth the Vcombination of, a stationary tubularv section, an annular bead formed on the stationary section adjacent its outer end, means formed on the Vinner end of the stationary section for securing
