CHIMNEY CONSTRUCTIGN.

application. ieafranuary 25, 192e. serai no. 614,117.

To all whom t may concern.'

Be it known that l, FRANCK E. ALBINI, a citizen of the Republic of Switzerland, residing at Stockton, county of San Joaquin, State of California, have invented certain new and useful lmprovements in Chimney Construction; and I do declare the following to be a full, clear, and exact description of the same, r ference being had to the accompanying drawings and to the characters of reference marked thereon, which form a part of this application.

rlhis invention relates to improvements in the construction of chimneys and particularly to that portion thereof above the building and exposed to the wind, the principal object of my invention is to provide a device for exterior attachment to any chimne;T flue by means of which the draft through the flue is greatly increased, particularly when a wind is blowing, and regardless of the direction thereof, and the common tendency of gusty winds to cause a back draft in the flue is eliminated.

The device also prevents rain from blowing down the chimney.

Another object of the invention is to provide a means for spraying water both down the chimney and on the roof adjacent the same in the event that accumulated soot in the chimney should catch fire, as frequently occurs. n

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed. l

rThese objects I accomplish by meansof such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

ln the drawings similar characters of reference indicate corresponding parts in the several views.

Fig. l is a side elevation of the assembled structure, partly in section.

Fig. 2 is an end view of the same.

Referring now more particularly to the characters of reference on the drawings, the

numeral l denotes a straight vertical chimney or flue portion, adapted to be mounted on the fixed building flue just above the roof of the building in which the flue is located.

Horizontal laterals 2 extend from opposite sides of said flue intermediate its ends, at the outer ends of which laterals are short open ended Ventilating ilues 3, parallel to the main flue in the common plane thereof, but sloping theretoward from their lower to their upper ends, which are below the @0 upper end of the main flue.

The main flue, laterals and Ventilating flues all freely communicate with each other, and are secured together to form a rigid unit.

Surrounding the top of the flue l, and' spaced therefrom all around, is a frustoconical collar fl, projecting outwardly at its lower end far enough to receive some of the draft of air passing up through the side ilues 3, and extending above said main flue for a certain distance.

Projecting upwardly valongside the flue l is a water pipe, leading from the exterior of the building and connected to any controlled source 0f supply.

The upper end of said pipe overhangs the flue l a certain distance thereabove, and terminates in a vertically disposed spray nozzle 6 facing downwardly into the flue and located centrally thereof. This nozzle is arranged to direct a stream of water, when the latter is turned on, not only down the chimney, but outside and around the same over a certain area.

Mounted on the pipe 5 above the nozzle and in alinement with the axis of the flue is a vertical stem 7, forming a support for a flat cone-shaped hood 8, set at a slight angle from a horizontal plane, and having, on its high side and at a point removed from or eccentric to the apex of the hood, a sleeve 9 in which the stem 7 seats, said sleeve being turnable on the stem.

Fixed on the cone and projecting from the sleeve to a point a certain distance beyond the adjacent side-edge thereof and positioned in the plane of a radial line drawn through the cone-apex and sleeve 9 is a vane 10, having a counterweight member l1 thereon to balance the oset weight of the cone relative to its point of support.

Secured to and under the cone on the side thereof opposite to the vane and positioned substantially in a transverse plane at right angles to the latter is a baffle plate or deiector 12, sloping away from the chimney from top to bottom, and having a horizontal curvature from side to side, the center of which is on the inner side thereof.

The lower periphery of this plate is also preferably curved so as to be substantially semi-circular in shape, projecting below the top of the iiue l, while the upper edge thereof is spaced intermediate its ends iroiii the hood 8, as shown at i3.

From the above description it will be evident that with a blowing of the winda the hood 8 will be rotated so as to bring the vane 10 in line with the wind and with the baiile l2 on the Windward side of the chimney. The wind is thus prevented `freni passing directly over the chimney, but must pass around the deleetor, which lwider than the chininey7 fit iiiay pass, as seine of it does, between the de' cctor and hood.

A. substantially horizontal draft is therefore created a certain distance above the flue, which of course increases the draft through the latter.

it the saine time, an upward draft is also created by the passage of between tl 11G collar l and 'flue l, and up through the side fines 3 which in turn creates a draft in the 7 1 f u laterale 2 and diie i, the whole combination 'd' 7 e?? 'of i- 1w, ft H 1 1 H i piovi ing a very iiiciciit @iii iiiocgn ,.ic main iiue, eliminating the possibility of any Wind blowing down the chimney and causing a back-draft.

The pipe 5, as will be seen9 not only provides an insurance against chimney lires and root iires caused by overheated i'lues, but serves as the ineans by which the hood and its attached parts are supportel.

From the foregoing description it will he readily seen that l have produced such a device as substantially fulfills the objects oit' the invention as set forth herein.

While this specification sets "rorth in detail the present and preferred construction incarne of the device, still in practice such deviations frein such detail may be resorted to as do not forni a departure freni the spirit of the invention, as defined by the appended claims.

Having thus described my invention, what ll claiin as new and iisetul and desire to secure by Letters Patent is:

l. An exterior chiiniiey structure comprising a vertical iiue portion, laterale leading -troni the iiue intermediate its ends3 and open-ended Ventilating` iiues connected intermediate their eiidsiwith the iaterals, said ventilating iliies sloping toward the niain liue Jfreni bottoni to top and terminating short oit the top or said inaiii fine, and a collar 'lic-ring` outwardly roni top to bottom iixed on top of' tie inain flue, said collar being)` positioned to receive 'soineiof the airdratt rising` through the Ventilating iiues.

2. [in exterior chimney structure comprising vertical ilue, a hood over the flue, said hood beingY it'orined as a `dat cone and being disposed relative to the iliie so that the apex of the hood is to one side of the center of the flue and the hood has then a substantially horizontal portion on one side of its apex eX- tending` centraily over the flue, while the hood on the opposite side of its apex proects at a downward aiivfle be 7ond the iiue and a deiiector plate projecting downwardly troni said other side or" the hood to a point below the top of the flue, said plate being arranged to cause a current of air strikingthe saine to iinpinge against the substantially horizontal face of the hood.

lin testimony whereof l aiiix niy signature.

FRANCK E. ALBlNl.
