Be it knownthat I, vMAX CLEMEN'S SCHU- BERT, a citi'zenofv Germany, residing aty I do hereby declare the following to be a ful-l, clear, and exact description of the invention,

such as will enable others Skilled inthe art to which vit appertain's'to. make and use the same.

My invention relates tochimney-cowls and caps or partial closures for the -upperends of i chimney-fines, stacks, *or Ventilating-pipes.

It comprises a systematic arrangement of deflectorsand hoods designed a vd adapted to'cxclude all objectionable doszndrafts or counter-currents, at same time.A permitting and encouraging the unrestricted egress of smoke, waste products of combustion, and gases from within.

The invention also performs the functions of `a spark-arrester anc serves at all times to preserve the chimney, stack, or pipe from damaging eects of the elements by closing the outlet end thereof against the admission of rain and snow. i

The invention will he hereinafter described, and particularly pointed ont in the claims following.

In the accompanying drawings, which form Y part of' this specification, and whereon cor' responding letters of reference indicate the same parts in the several views, Figure l represents a side elevation of the invention applied to the upper outlet end of a stack. Fig. 2 is a central vertical section of salme, and Fig. 3 is a side View of one of the continuous angle-irons employed as a frame upon PATENT OEErcE.

Secured to the frame-irons 'D at points abOY-.Q

stack A isan upwardly-,divergingannular" jacket F; which practically forms a'lcoxntir1u4 5 5 ation of the,l stack, though" ofginc'rea'seddi-g ameter, and vis finished ati-"1 sjlow Idgle b f aslight overhang af, alsodifver'gig t wardly extending. "f, [f1.1

Within the confines of 'frainea po'i' ,I approximating the upperedg'e lof*`` et EQ, are secured radial strapsiI'I I', affording e,- support for ahollow defleting-drunifht l h' ocmp'ying` a position inl;tire'jce'titer of the,l` structure and of double conical shape, bavving'y oppositely-disp'osed apexes G G and al common base H for purposes that will later appear, l

Surrounding the upper end of drum Fand also 'overhanging jacket E is a centrally-perforated' converging hood J, serving principally asa dellector for' outside currents and drafts. The said hood is also secured to frame D by rivets or otherwise and is surmounted by a conical cap L, serving'as a closure for the upper end of the structure.;

This being a description of the invention, its operation and effect are as follows: Smoke and waste products of combustion or gases rising naturally through stack A first come in cont'fct withthe lowermost end of drum F,

projez 1 slightly into the flaring extremity B of the stack, and are thereby deiiected, findinf; vent between' jacket E and hood J through the aperture K, or if under influence of an upward exterior draft said aperture'is passed` theymust necessarily escape through aper. ture N above. On the other hand, it will be observed that no direct gush orrush of air can enter at the aperture M, any upward c'urrent or |suction being checked by the baseof the collar C, a downward current being thrown off by the` lower outward flare of the jacket E, while a horizontal or upwardly-inclined current is modified by contact with the outer side of the flaring collar C and the upwardlyflaring end of pipe A, sending a gentle current into the jacket E, which by contact with the lower portion of the drum F is deiiected upward, sufficiently stimulating the draft` to carry the smoke and gas upward to the aperture K, where it escapes to the atmosphere. The wind coming in at the aperture K strikes the upper portion of drum F, by which the rupted escape of smoke.

current" is broken and deflected upwardly,l and it will be observed that the draft will be disturbed only in the quarter froufwhich the Wind is blowing, ,leaving at least three-fourths v of the annular spacebetwecn the jacket' E and the drum F for the free and uniuter The aperture N bctween the section J and cap L allows the heat to escape to the atmosphere, while the cap L prevents the Wud'uor rain" from entering at the top. l

Having thus described myiuveution, what f 1.' Ina chimney I-clam, and desire to secure by Letters Patr,
