Specification of Letters Patent.
Application filed June 24, 1907.
Patented June 30, 1908.
Serial No. 380,480.
To all whom it may concern:
Be it known that I, O'rro SCHUBERT, a subject of the King of Prussia, and a resident of Charlottenburg, near Berlin, in the Kingdom of Prussia and German Empire, have invented new and useful Improvements in Cowls, of which the following is a specification.
My invention relates to an improved chimney top or cowl, comprising two superposed tubular sections united by a ball and socket joint, so that the upper section can adjust itself according to the direction of the wind.
The invention is illustrated in the accompanying drawing, in which Figure l is a vertical section through a cowl, Fig. 2 a vertical section throu h the top cowl pipe, and Fi 3 a sectiona view showing to a larger scje a detail to be hereinafter referred to. Fig. 4 is an elevation of the cowl.
The cowl consists of two main parts: the fixed pipe A and the movable pipe B superposed thereon. The top of the pipe A has the form of a truncated sphere a, which is received by the foot of the pipe B, which has somewhat the shape of an inverted cup I). The two arts 0. and I) thus constitute a socalled bal and socket joint. The ball a contains a s ider or the like h, supporting a hardened stee boss g, presenting a point exactly in the center of the ball a. The pipe B contains a spider or the like (I at whose center there is secured a dependent rod 0. The end of the rod is hardened and presents a recess to receive the point of the boss g, on which it rests. At the bottom of the rod 0 there is secured an annular cross c, with pendent balance-weight.
It is obvious that owing to the ball and socket joint the section B will yield to the force of the Wind and bend over more or less in the direction of the latter, as indicated by dotted lines in Fig. 1. On abatement of the wind the weight fwill return the section B to its normal upright position (Fig. l).
WVhatever position the section B may occupy, it is clear that the smoke from the chimney will always pass from the pipe A through the pipe B.
Having thus described my invention, I claim as new:-
1. A cowl comprising two superposed tubular sections in which the top of the lower section has the "form of a truncated sphere, which is embraced by the cupped foot of the upper section, the lower section having a device presenting a central bearing point on which the upper section rests by means of a rod connected therewith substantially as described.
2. A cowl, comprising a lower tubular section whose top has the form of a truncated sphere; a device presenting a central bearing oint secured in this section; an upper tubuar section having a cupped foot which enibraees the top of the lower section; and a member secured centrally in the upper sec tion and resting upon said point; substantially as described.
3. A cowl, comprising a lower tubular section whose top has the form of a truncated sphere; a device presenting a central bearing oint secured in this section; an upper tubuar section having a cupped foot which embraces the top of the lower section; a pendent member secured centrally in the upper section and resting upon said point; and a balance-weight attached to said pendent member; substantially as described.
In testimony whereof I aflix my signature in presence of two witnesses.
