The root10 of a building 1 1 isprovided asuitable roundgop'enin'g receiving the lower or inner end of the tubular body of stack-12' of my .iimprov'em'ent The stack has secured thereon a suitable flanged collar 13 which surrounds the 'openingin the roof and which is secured to the roof. The tuibular stack 12 is provided with right aneullarly arranged partitionsl l extending the entire length of the said stack dividing the interior thereof into four separate lines 1'5 1-5. The stack 12, adjacent to its outer end, and upon its outer surface, is provided with a plurality of spaced spring finge'r's 16.
The hood or cowl for the tubular stack is broadly indicated by the numeral 17, the same also comprising a tubular body hav iiig a conical top 18. In the top. and at a suitable distance inward, of the edge thereof is secured, man desired or preferred manii'er an annular member or ring 19;, while at the botton'rof the s id cowl is a n d I similar ring 20, The rings 19 and 20. areconnected by afseries of inner and outer members 21 and "22 respectively, the said 'men'ibe'r's in connection with the rings formingth'e side or bodyot the cowl. v
,Th e inner members, it will be noted, by reference to the drawings are approximately "Speciiica tion of t'tte'rsrieht. Paten'ted Dec. 31, 1918. Applicatioil fiiedeu ust'sr-ie v. serial No. 189,147; I
semi-cylindrical in cross section having their edges flanged inwardly, as at 23, and these flanges are secured, in any desired or preferred manner, to the inner periphery of the ring members 19 and 20, the lower edges of the said semi-cylindrical members being projected a suitable distance below the lower ring member 20, as clearly illustrated by the drawings. The outer members 22 comprise plates which are centrally bent upon them selves, so that the same comprise angle members and the edges of these members are secured to the outer periphery of the ring members 19 and 20, in such a manner as to each bridge two of the inner members 21. The outer members or plates are properly spaced away from each other as are the inner members 21, and the spaces provided between the said spaced inner and outer members provide both the air entrance and the air outlet passages of the device. The cowl is designed to he slipped over the outer end of the stack 12, certain of the -crosssectionally U-shaped'members comprising the inner wall of the cowl, being engaged by the spring fingers 16 to effectively sustain the cowl upon the stack. The arrangement of the inner and outer walls of the cowl, providing the air passages ftherebetween is such that the air will take a tortuous path or direction in enteringthe stack and be directed through the flues thereof to the build ing, and likewise, the air from the building will take a similar path in finding an exit through the passages in the cowl. The arrangement is also such that regardless of the operation of the aircurrents on the exterior of the building, certain of such currents by the numeral 24. the same including a flat cylindrical top. plate 25, having upon its outer face a circular band or ring 26. While secured to the inner face of the said top 25 is two right angularly disposed plates 272' 7, each, in the nature of a right angular member, and the apex of these plates are spaced away from each other, whereby both of the said plates may be snugly received in two of the diametrically o posite flues 15 in the stack 12, the said plates serving as protecting means for the valve proper.
To the plate or top 25 of the valve 24, near the center thereof, is secured one end of a flexible elementpr'eferablv in the nature of a a grooved pulley 29 journaled in a suitable hanger 30 that is secured in the center of the be arranged in convenient proximity to the.
operator of the valve from the interior of the building, and upon the said interior of the building is arranged suitable means for holding the chain, whereby the valve maybe retained in' proper regulated position.
