STPECIFIGATION forming part of Letters Patent No. 623,134, dated April 18, 1899.
Application filed August 12, 1898. Serial No. 688,412. (No model.)
To all whont it may concern:
Be it known that we, HARRY C. CLAY and MARSHAL T. REEVES, citizens of the United States, residing at Columbus, in the county of Bartholomew and State of Indiana, have invented a new and useful Smoke-Stack and Spark-Arrester, of which the following is a specification.
Our invention relates to an improvement in smoke-stacks and spark-arresters.
The object of our invention is to produce a spark-arrestin g stack in which the sparks and cinders may be returned to the fire-box, in which the outer shell of the stack may be kept so cool as not to injure the paint thereon, and in which the spark-arresting device may be moved so as to increase the draft through the stack.
The accompanying drawings illustrate our invention.
Figure 1 is a central vertical section thereof. Fig. 2 is apartial section at right angles to Fig. 1. Fig. 3 is a sectional view of a modified form. Fig. 4 is a section on line 4 4 of Fig. 1. Fig. 5 is a section on line 5 5, Fig. 1.
In the drawings, 6 indicates a base-casting provided with a central opening,around which is formed an upwardly-extending annular flange 7. Upon the inner periphery of flange 7 is a series of separated lugs 8. Secured to the outer periphery of flange 7 is the lower end of the outer shell 9 of the stack, the upper end of which may be, if desired, oflarger diameter than the lower end. Secured to the upper end of the shell 9 is a cap-ring 10, the upper edge of which is beveled, as at 11, so as to receive an inverted conical ring 12, to the outer periphery of the smaller or lower end of which is secured the base of an inverted conical screen 13. Secured to the inner ends of lugs 8 is the lower end of the inner shell 14, the arrangement being such that a series of openings is left between the outside of the inner shell and the flange '7. The upper end of the shell 14 is held in position by means of a series of rivets 16, which are surrounded by thimbles 17, which extend between the two shells.
In the modification shown in Fig. 3 a supplemental inner shell 18 of larger diameter than the shell 14, but of smaller diameter than that portion of the outer shell in which it is mounted, is placed with its lower end slightly lower than the upper end of the shell 14, the said lower end beingheld in position by means of rivets 19, the said rivets passing through the three shells and being surrounded by thimbles 20 and 20, which extend between the shells 14 and 1S and 18 and 9, respectively. The upper end of the supplemental shell is held in position by ,means of rivets 21 and thimbles 22. The arrangement of shell 18 is such that an annular space 23 is left between its lower.
end and the upper end of the shell 14, and a similar space 24 is left between its upper end and the screen-cone.
For the purpose of raising the screen-cone from its normal position we secure to oppo site sides of the ring 12 a pair of depending bars 25, which pass alongside the shell 9 through openings 26, formed in the cap-ring 10, the sides of said openings forming guides for maintaining the bars 25 in upright positions. Secured to the outside of shell 9 is a bearing-lug 27, to which is pivoted a yoke 28, thearms 29 and 30 of which are pivoted to the lower ends of the bars 25. Secured to the outer or free end of the yoke 28is a cross-bar 31, to the upper end of which may be secured a rope or cable by means of which the yoke may be swung upon its pivot and the lower end of which is in such position that when the yoke is swung so as to raise the screencone the said lower end will be thrown into engagement with the shell 9, and thus act as a stop to prevent a further upward movement of the screen-cone.
The operation is as follows: The smoke as it issues from the fire-box passes upward through the inner shell 14, and the .cinders carried by said smoke are deflected by the screen-cone 14 and caused to drop down between the two shells 9 and 14 and to pass back into the fire-box through the openings 15 between the lugs of the base-casting. By this means the usual accumulation of cinders inside the outer shell and the consequent burning of the paint on said shell is avoided.
In the modification shown in Fig. 3 the cinders pass down over the top of the innershell 14 between it and the supplemental shell 18 and also pass over the top of the supplemental shell, the cinders in both instances passing down through the openings into the fire-box.
The screen-cone cuts down the draft to some extent, and in order to increase the draft the screen-cone may be lifted vertically into the position shown in dotted lines in Fig. 2, thus opening a clear outlet from the outer shell.
e claim as our invention 1. In a smoke-stack, an annular base-casting having lugs 8 in its inner periphery, an outer shell secured at its lower end to said casting, an inner shell secured at its lower end to the inner ends of said lugs, a second inner shell, of larger diameter than the first mentioned inner shell, a series of rivets passing through the outer shell, the lower end of the second inner shell and the upper end of the firstinner shell, a series of thimbles placed over said rivets between the two innershells, a series of thimbles placed over said rivets between the second inner shell and the outer shell, a series of rivets passing through the outer shell and the upper end of the second inner shell, and thimbles placed over said rivets between the two shells.
2. In a smoke-stack, the combination with the shell thereof, of a cap-ring secured to the top thereof, a spark-arresting screen mounted in said shell, a pair of bars secured to said screen and extending down alongside the outside of the shell through the cap-ring, and a yoke pivoted to said shell and having its arms in engagement with said bars.
3. In a smoke-stack, the combination with the shell thereof, of a spark-arresting screen mounted therein, a pair of bars secured to said screen and extending down alongside the outside of the shell, a yoke pivoted to said shell and having its arms connected to said bars, and a cross-bar carried by said yoke one end of said bar being in a position to engage the shell and limit the movement of the yoke and consequent movement of the bars and screen, substantially as described.
4, In a smoke-stack, the combination with the shell thereof, of a cap-ring secured to the top thereof, a spark-arresting screen mounted in said shell, a pair of bars secured to said screen and extending down alongside the outside of the shell through the cap-ring, a yoke pivoted to said shell and having its arms connected to said bars, and means carried by said yoke for limiting the movement of said yoke.
