' SPECIFICATION forming part of Letters Patent No. 300,079, dated June 10, 1884.
Application filed lilarch 7, 1884. (No model.)
To aZZ whom it may concern:
Be it known that we, J. WORTH J AOKMAN,
HERBERT B. NEIGHBOR, JOHN R. Simon, and
SAMUEL F. HABLITZEL, citizens of theUnited States, residing at Lafayette, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Chimney-Oowls, of which the following is a specification.
The object of our invention is to prevent the wind from blowing down the throat of a chimney, causing it to smoke, by providing it with a top so constructed that itmay revolve like a weather-vane, with its mouth always to the leeward.
The invention consists in a metallic elbow of pipe provided with a counterbalance weight, mounted over the chimney-cowl upon suitable friction rollers or travelers, upon which it may easily turn, and stayed in an unvarying upright position by means of an additional bearing between the rollers and the turn in the elbow,-as will be more fully described. 2 5 In the accompanying drawings, Figure 1 represents the invention and a portion of the chimney in perspective; Fig. 2, a longitudinal section of the lower part of the device, showing the detail of its construction.
The elbow A is similar in general outline to those in common use, its mouth opening at right angles to the throat of the chimney. In order that it may turn with the least possible friction and without the possibility of binding, it is provided with an overhanging weight, B, to counterbalance the weight of the elbow opposite thereto. This is so simple as to require no description. In addition to this, the elbow is stayed in an upright position by an encircling collar, G, of wire or other suitable material, properly braced in all directions, and forming a bearing a little below the turn in the elbow, in which the latter is free to revolve. The bottom of the elbow is provided with a flange, b, which rests upon small friction-rollers or travelers to a, mounted on a suitable base, 0. The base is provided with an annular casing, c, which covers the rollers, and the horizontal portion of which pro- 50 jects inward over the flange of the elbow and prevents displacement by lifting. To render the action of the elbow still more certain and perfect, it is made to revolve around a ring, D, secured to the base G, and extending upward a short distance inside the vertical por-. tion of the elbow. The common tendency toward lateral strain, and consequent binding in the bearings, due to top-heaviness and to the center of gravity being outside the center of motion, is still further reduced by plac- 6o ing the vane E under the mouth of the elbow, instead of above it. This brings the pressure of the wind opposite the upper bearing, as will be seen by reference to Fig. 1, and insures prompt and smooth action on the part of the elbow. The lower working parts are protected from the elements by a flaring hood, F.
Thus constructed, the device forms a top for a chimney which revolves with very little 7o friction and with no possibility of sticking and binding. The result is that it acts quickly and freely, without which qualities no chim- -'ney -cowl is a certain preventive against smoking chimneys in gusty weather.
Having thus briefly described our invention, what we claim as new, and desire to secure by Letters Patent, is-
1. In a chimney-cowl, the elbow stayed near the curvature therein by an encircling 8o bearing, and provided with an annular flange at or near the bottom, resting upon anti-friction rollers pivoted in the base, substantially as shown and described.
2. In a chimney-cowl, the combination of elbow A, counter-balance 13, upper bearing,
G, flange b, and rollers a a, all constructed, arranged, and operating substantially as and for the purpose set forth.
3. In a chimney-cowl, the combination of 0 elbow A, counter-balance B, upper bearing,
G, flange b, rollers a a, casing 0, ring D, hood F, and vane E, all substantially as shown and described.
In testimony whereof we aflix our signatures 5 in presence of two witnesses.
