nnnr'r APPLIANCE- FOR oHIMnEYs on. VENTILATOR-STACKS.
Specification of Letters iatent. Patented J 11119 29, 1920.
Application filed September 29, 1919. Serial No, 327,267.
T 0 all whom'it may concern: Be ,it known that I, ALFRED JoNns, a citizen of the. United States, and a resident of the cityof Chicago, county of Cook, and State of Illinois, have inventedcertain new and useful Improvements in Draft Appl1 ances for Chimneys or Ventilator-Stacks, of which the following is a full, true, and exact description, reference being had to the accompanying drawing, forming a part of this specification.
This invention relates to draft appliances for chimneys or ventilator stacks and its principal object is to increase the efficiency of devices of this character. Another obj ect is to provide improved means for positively directing currents of passing air upward around the smoke flue and over the top of the same, to thereby increase the draft. The invention consists in the several novel features hereinafter fully set forth and claimed.
The invention is clearly illustrated in the accompanying drawing, in which Figure 1 is a perspective view of a draft appliance embodying a simple form of the present invention; Fig. 2 is a central, vertical section therethrough; Fig. 3 is a horizontal section taken on line 33 of Fig. 2; Fig. 4 is a horizontal section taken on line 4-4 of Fig. 2, and Fig. 5 is a fragmental, vertical section taken on line 5-5 of Fig. 3.
Referring to said drawing, the reference character 6 designates a chimney of ordinary construction and 7 designates the draft appliance. The device is preferably constructed of upper and lower, separable sections 8, 9, the lower section 9 having a rectangular base portion 10 surrounding and resting upon the chimney top. The sides 11, of the lower section are flat, and incline upward toward the center of the device; at the upper end of the flat, inclined sides, is a tubular end or pipe 12.
Riveted or otherwise secured to the corners made by the inclined sides .11, are
maybe made ofsheet metal, bent upon themselves as is clearly shown in Fig. 4 and they have base portions or webs '15 that fit around the corners and are riveted to the inclined sides 11.
The upper section 8 comprises a tubular stack. 16 having upon its lower end an out wardly and downwardly flaring hood 17 that rests upon the wings 13 (seeFig, 5).
and said wings may be tapered toward their upper ends, as at 18, to fit against the inner face of the hood 17 The stack 16 is somewhat larger in diameter than the tubular end or pipe 12 of the lower section and it is spaced away therefrom by struts or other spacers 19 preferably riveted or otherwise secured to the pipe 12. It is to be observed that an annular air passage 20 is left between inclined sides 11 and hood 17 which is continued upward between the pipe 12 and stack 16, as at 20*- Above the stack 16 is supported a conical water shed '21 which may be secured to the stack 16 by metal strips 22. A band of metal 23 is fastened to the stack 16 near its upper end and is formed with loops 24, to which guy wires may be secured for the purpose of steadying the stack 16.
In operation, any current of air striking any inclined side 11 is caught between the wings 13 at the edges of that side, and directed upwardv into the annular space 20 between the upper ends of the inclined side and hood 17, from which it passes up through the annular space 20 and passes out through the upperv open end of the stack 16, producing an injector-like action and drawing the smoke or other gases up through the lower section 9, and discharging them out through the upper end of the stack 16. The arrows a, in Fig. 2, indicate the passage, through the device, of a current of air, moving in a direction from right to left in Fig. 2, and the arrows 12 indicate the passage of smoke or other gases through the device.
Obviously, the appliance may be secured upon the top of ventilator stacks and may be used for ventilating purposes, as is well understood.
More or less variation of the exact details of construction is possible without departing from the spirit of this invention; I desire, therefore, not to limit myself to the exact form of the construction shown and described, but intend in the following claims to point out all of the invention described herein.
I claim as my invention:
1. A draft appliance, comprising a rectangular'base portion having upwardly and inwardly inclined, flat sides,terminating in a tubular end, and wings secured to the 7 sides at the corners thereof and formed with transverse flanges, said inclined sides, with their flanged wings, converging upwardly toward each other, and a stack spaced away from and surrounding said tubular end and having a downwardly and outwardly flaring hood resting upon and supported by said wmgs. V
2. A draft appliance, comprising a rectangular base portion having upwardly inclined, flat sides, terminating in a tubular end, and wings secured thereto at the corners, and formed with transverse flanges, said inclined sides, with their flanged wings, converging upwardly toward each other,
and a removable stack surrounding and .spaced away from said tubular end and having a downwardlly an outwardly flaring hood resting upon and'supported by said wings, said inclined sides, wings and hood forming'individual air passages, disposed around theupper end of the base portion.
3. A draft appliance, comprising upper and lower sections,.the upper section comprising a stack having a downwardly and outwardly flaring hood at its lower end, and the lower section comprising a rectangular base formed with individual upwardly inclined trough-like members disposed around a common center and converging toward each other, the edges of said trough like members having transverse flanges extending to and under said hood and forming the support for said upper section, there being 7 a tubular end atthe top of the inclined trough-like members projecting up into said stack. v
ALFRED JONES.
