\VILLIAM B. GROWTHER, SR, OF OCEAN BEACH, NEW JERSEY.
CHIMNEY COWL AND VENTILATOR.
SPECIFICATION forming part of Letters Patent No. 357,269, dated February 8, 1887.
Application filed September 2, 1886. Serial No. $2,506. (No modelal To all whom itmay concern.-
Be it known that I, WILLIAM B. GRowTHEn, Sr., a citizen of the United States, residing at Ocean Beach, in the county of- Monmouth and State of NewJersey, have invented a new and useful Improvement in Chimney Gowls and Ventilators, of which the following is a specifi-' cation.
My invention relates to an improvement in chimney cowls and ventilators; and it consists in the peculiar construction and combinationof devices, that willbe more fully set forth hereinafter, and particularly pointed out in the claims.
In the drawings, Figure 1 is partly a side elevation of my invention and partly a vertical longitudinal sectional view of the same. Fig. 2 is a vertical section taken on the line a a; of Fig. 1. Fig. 3 is a detached perspective view of the spreading cone.
A represents a vertical cylindrical pipe which projects from the upper end of the chimney, and is provided with a vertical pivotal stem, B, which projects above its upper end and at the center of the pipe.
0 representsa cowl, comprising a funnel, D, which is arranged horizontally, and avertical sleeve, E, which depends from the lower side of the funnel D, near the center thereof. The said sleeve is provided near its lower end with a horizontal cross-bar, F, which rests upon the upper-edge of the pipe A, and the stem B 'of the latter passes through an opening which is made in the center of the crossbar, and has its upper end journaled in the rear end of a funnel, G, which is inserted in the large end of the funnel D, so as to contract the opening in the said latter fuhnel. By this means it will be readily understood that the cowl is adapted to rotate on the upper end of the pipe A. The rear end of the funnel" Gproj ects somewhat beyond the center of the sleeve E, and to the rear end of the said funnel and supported at a slight distance in rear thereof is secured a spreading cone, H, the apex of which is in a line with the longitudinal center of the funnel G. This cone is provided with an opening at its apex, so as to permit the free circulation of air entirely through the cone.
I represents a vane .or wing, which is attached to the rear end of the funnel D, on the rearwardly from the said funnel.
upper side thereof, and projects vertically and The operation of my invention is as follows:
The vane serves to keep the mouth of the funnel D, and consequently the mouth of the funnel G is always directed, toward thewind, and a current of wind is thus caused to constantly pass through the funnel D and over the chimney. This creates a partial vacuum in the chimney and causes the air to rush upwardly therein, thus preventing the chimney from smoking by insuring active combustion, and also thoroughly ventilating the room in which the fire-place of the chimney is located. The
function of the spreading cone is to divert the current of air which passes through the funnel D and the induction-funnel G, and causes it to strike against the sides of the rear portion of the funnel D in a thin spray, and also to give a spiral orcycloidal motion to the current of air,
and thus increase the efficiency of the device,
as a ventilator. The air rushing through the funnel G is partly deflected by the cone H against .the sides of funnel D, and partially enters through the cone by means of the'opening in the apex thereof. This combined action of the air produces a whirling or cycloidal motion, as will be obvious.
It will be readily understood that the device is not necessarily limited to use on chimneys, as it may be readily employed to ventilate buildings without being placed upon chimneys, the only requisite being that the lower end of the pipe Ashall communicate with the apartment which itis desired to ventilate.
The spreading cone H is secured to the funnel by means of rods J, as shown in Fig. 3, that are soldered to the outside of the funnel.
To provide an anti'friction bearing for the stem B, I secure at the top of the cowl a tin piece, T, having guides or ways for a glass block, L, formed with a seat, m, for the upper conical end of the stem.
The cross-bar F, resting 011 the top of pipe A, supports the sleeve Eand funnel D; but to efl'ectually prevent the latter from being blown over, the pivotal rod or stem B passes through the funnel G.
By having the spiral motion to occur at a smoke arising therefrom cannot be blown down the chimney, but, on the contrary, the whlr1- ing or spiral motion will serve to exhaust or extract the smoke and provide an excellent draft, that will materially assist in making the fire burn.
Having thus fully described my invention, I claim- 1. In combination with the funnel D, the induction-funnel G, extending from one open end of the funnel D, the spreading cone H, having its open end projected into the open inner end of the funnel G, and the rods J, secured to the cone H and adapted to secure the same to the funnel G, as set forth.
