CHIM N EY-COWL..

SPECIFICATION forming part of Letters Patent No. 519,954, dated May 15, 1894.

Application filed January 19, 1894. Serial No. 49'71433- (NO mOdGl-i To all whom it may concern: Be it known that I, JosEPH A. HoDEL, o Cumberland, in the county of Allegany and State of Maryland, have invented a new and useful Improvement in Chimney-(lewis, of

which the following is a specification.

My invention is an improvement in chimney cowls and has for its objects am ong others to incase t-he vane so it will form no unsightly projection beyond the topeither above or to one side thereof, to so support the draft regulator that it can turn freely and can be readily adjusted when bearings are worn7 to provlde ready outlet for water that may beat into the top and to prevent the accumulation of soot therein. The invention has forfurther objects other improvements and consists in the novel constructions, combinations and arrangements of parts as will be hereinafter described and pointed out in the claims.

In the drawings-Figure l shows the invention embodied in a double Hue the line and the lower portion of the top being shown in vertical section. Fig. 2 is a vertical section on about line 2-2 of Fig. l. Fig. 3 is a detail view of the draft regulator and vane; and Fig. 4 is a detail sectional view.

I have shown my invention applied to a double line but. manifestly it may be applied to a single fine if desired.

In applying the improvement to a double iiue the base plates A which cap the chimney are formed to abut at their meeting edges a or and the tops B have at their meeting edges or joint upwardly projected beads l) and such joint is capped by a ridge plate C which may be secured by the same bolts or rivets O C that secure the top B to the base plate A. This is important as it protects the joint of the covers and of the base plate from rain and the like as will be readily understood from Fig. l. At its lower outer edges the top has liange extensions B which serve to shed rain, dac., away from the chimney. The tubular or y lower portion D of the top preferably converges to a point cl where it abruptly dares outward and is prolonged into a lateral iange d whence it tapers inward its tapered or conical portion cl2 merging into the short cylindrical rim cl3 which is preferably shouldered at d4 on its outer side as shown.

the shaft F. The upper section Gof the cowl j is provided at its lower end with the legs G having their feet or lower ends g flared outward and rest-ed against and secured to the cone d2. The spaces between the legs G form the openings H through which the wind enters and the wind, smoke, &c.,discharge from the cowl. Above the openings I-I the cowl is imperforate and is widened out at I forming internally spaces for the play of the vane presently described. The roof J slopes downward from the crown j it may be rounded as shown or tapered if desired and is extended atj to shed rain clearof the inlet and outlet openings H. At its crown j the roof supports the bolt L which has at its lower end a bearing l for the shaft F and this bolt may be adjusted and held in any desired adjustment by nuts L L2 above and below the roof. This provides for the proper setting of the shaft in the first instance and for subsequent adj ustments to take up wear or for any other purpose desired. The shaft F extends between and journals in the bearings Zand c and upon it is secured the wind regulator M Whose top and sides except for the outlet opening M may be closed as shown. This regulator lits at its lower edge over top rim cl3 of the lower section and above the shoulder d4 such formation operating to prevent ingress of wind to the regulator at the side opposite the outlet opening M. To the inner side of the regulator is secured a scraper N which projects down inside the rim d3 and operates to scrape accumulations of soot, the., from said rim so it will drop down within the chimney. The vane O has its shank like portion O fixed to the shaft F within the regulator andthe vane projects out through the opening M in the regulator and plays within the cowl as shown. Now the arrangement of the vane entirely within the cowl is important as it hides the vane from view and also protects the said vane from the weather so that it is not so likely to rust as when exposed to rain, snow, dsc.

In operation the wind entering the openings II will strike the vane and operate upon the same to turn it and the outlet openingin the regulator to the lee side of the cowl so the smoke, the., passing up will be properly discharged. The vane being arranged within the cowl and between the shaft bearings its strain is evenly distributed upon the shaft and the bearings thereof are relieved of unequal strain and wear as will be understood from the drawings.

For use on rail road cars, steamboats and the like where the cowl is subjected to opposing currents of air the top of the regulator may be provided with outlet openings as indicated in dotted lines in Fig. 2.

While it may be preferred to connect the Vane with the regulator through the medium of the shaft it is manifest that it might be connected or fastened directly to the regulator without departing from the principles of the improvement.

In practice I cement the base plates upon the flues such plates being provided with openings to enable the cement to secure a better hold.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a chimney cowl the'base plates arranged to meet between the flues, the tops having their adjacent edges above the joint of the base plate provided with beads or lianges, the ridge plate covering such joint and the fastenings substantially as set forth.

2. A chimney cowl, provided with a revolving regulator and having a vane, connected with said regulator and arranged and operating entirely within the cowl substantially as set forth.

3. In a cowl substantially as described the regulator of the vane secured within said regulator and extended through t-he outlet opening thereof all substantially as set forth.

4. In a cowl the combination of the lower portion having at its top the cylindrical eX- ternally shouldered rim, and the regulator above said rim and fitted at its lower edge upon the said shouldered rim and a scraper connected with said regulator and operating within the said rim substantially as set forth.

5. The combination with a cowl, of the vane arranged within said cowl, and the part operated bythe said vane substantially as and for the purposes set forth.

6. The combination of the cowl, the shaft in said cowl, bearings for said shaft one of said bearings being adjustable and the regulator and vane secured to the said shaft, both the regulator and vane being arranged and operating within the cowl substantially as and for the purposes set forth.

7. A cowl having a lower section provided at its top with an inwardly tapered or conical portion, the upper section having at its lower edge legs provided with feet secured to said tapered or conical portion, the regulator operating in the cowl and the vane substantially as set forth.

8. The improved cowl herein described having the lower section provided with the inwardly tapered top the upper section having legs secured to the said top, the shaft arranged in the said cowl and the regulator and vane secured to the shaft and both arranged and operating within the cowl substantially as and for the purposes set forth.
