I. TTE SATES P AUGUSTUS C. HINCKLEY. OF .POCATELLO, IDAHO.
SPARK- ARRESTER.
To all whom it may concern Beit known that 'I, AUGUSTUS C. HINCK- LEY, a citizen of the United States, residing at Pocatello, in the county of Bannock and State of Idaho, have invented :motive without excessively obstructing or impairing the draft. 'After the sparks have been arrested and broken into small particles, they are entrapped within a cinv der jacket and then delivered by the one or more conduits or discharge pipes to a point adjacent to the road bed.
A further. object of the invention is to provide in connection with the apparatus above described, a draft regulating petticoat together with means controlled exteriorly of the boiler for adjusting the petticoat in its relation to the steam exhaust nozzle, whereby the area of the inlet zone of the petticoat may be increased or diminished in accordance with the existing conditions.
With the above and other objects in view,
the invention consists in the novel construction, combination and arrangement of :parts, as herein described, illustrated and claimed.
In the accompanying drawings :-Figure lzis a front elevation of-a sutficient part of a locomotive omitting the front plate of the smoke box to show in elevationcertain parts of this invention. Fig. 2 is a side elevation partly in vertical 'longitudi- 1 nal section of the same, showing the complete device. Fig. 3 is a bottom plan view of the cinder breaker. Fig. 4 is a section through the same.
Referring to the drawings, 1 designates the boiler of a locomotive, 2 the smoke box and 3 the rear wall of the smoke box, the smoke stack being designated generally at A and comprising the cylindrical body portion 4, the base 5 by which it is secured to the smoke box and the head section comprising the top section 5' which converges upwardly and the lower section 6 which Patented Mar. 14, 1916.
Application filed. September 8, 1915. Serial N 0. 49,569.
converges downwardly where it is united to the cylindrical body portion 4. The sections 5 and 6 are secured together by a slitted pipe ring as shown.
Within the head section is a cinder breaker 7, provided with annular cinder breaking ribs 16, said cinder breaker being supported by rods 8 with the upper portion threaded to receive nuts 11 and 12 at the upper and lower ends of the bosses 10, provided on the cinder breaker for this purpose. The threaded portions of these rods 8 are sufiicient in length to admit of raising and lowering the cinder breaker 7 to suit conditions, the lower portions of these rods being flattened and secured to the stack body 5, as shown at 9. The cinder breaker has the shape of a globe segment so as to deflect the cinders in oblique directions through openings numbered 17 to a cinder chamber 18. Cinders thus conveyed to the chamber 18 arenot exposed to draft any longer and by gravity fall to cones 34 which are provided with discharge pipes 33, discharging cinders to the road bed.
The cinder breaker 7 is provided on its under side with a plurality of concentric annular ribs 13 having oblique cinder deflecting side faces 14 and 15 and downwardly facing crests 16 which act to break up large cinders while the oblique surfaces 14 and 15 scatter the broken portions of the cinders which thereupon fall upon the downwardly converging portion 6 of the head section of the stack. The clownwardly converging portion 6 of the stack is formed with an annular series of cinder outlet ports 1'? through which the cinders may escape into a cinder jacket 18 which is preferably composed of sheet metal and which encircles the body 4 of the stack and also:the lower portion of the section 6 of the head of the stack. The jacket 18 is shown as made in upper and lower sections united together by a slitted pipe ring 19, the adjacent edges of the sections of the cinder jacket being deflected outwardly and inserted through a slit in the ring 19 and permanently secured together and to said ring in any approved manner.
The jacket 18 protects the body 4 from being worn and burned out by the falling cinders. Said cinder jacket 18 extends down to the smoke box and up over the lower portion of the headgsection and is fastened to the latter directly above the cinder discharge openings 17.
Within the smokebox 2 there I are arranged telescoping pettlcoat pipes comprising the upper stationary section 20 and the lower adjustable section 21, adapted to be raised orv lowered by means hereinafter described. The stationary petticoat pipe 20 must have proper clearance at the top between the smoke stack base 5 for overdraft. The stationary' petticoat pipe 20 is supported by means of clamp supports 22 connected to the smoke box; Adjustable petticoat pipe 21 is guided by telescoping into the stationary pipe 20 and by passing through the annular opening of the guide 28 fastened to the smoke box. Support 28 and guide 26 are connected together by means of braces 29 to insure stability of 'these'parts. l
The lower end of the section 21 of'the petticoat is provided with a flaring mouth piece 31 which is adapted to be located directly above the steam exhaust nozzle 32 located in the base of the smoke box.
The means for adjusting the'petticoat pipe 21 comprises a hand lever 33 on the outside of the smoke box connected to the shaft 34.
- Bearings for this shaft are placed internally and externally of the smoke box, the in-.
ternal bearings 35-being fastened to, the petticoat pipe guide 28. The external bearing 35 is fastened to the smoke box sheet. The shaft 3% is provided with arms 36 having slots 37 to receive pins 38 on the petticoat pipe 21, thus directing the adjustment of the petticoat pipe. Segment 41 fastened to the outside of the smoke box is provided with anumber of holes 40 to receive a set pin 39 for holding the lever 33 in any desired position.
The jcinders caught in the jacket 18 are conducted therefrom by means of one or more exhaust pipes 33 each provided at its receiving end with a flared throat piece 34 riveted at 35 to the cinder jacket 18. These throat pieces are sufficiently flaring to extend nearly one-half the way around the cin- I der jacket 18. The cinders gravitate through the pipes 33 and are directed downwardly toward the road bed.
, Thepetticoat pipe 2 1 can be adjusted at any time while the'locomotive is in motion or at rest, and thus the arrangement can be adjusted to suit forced draft conditions;
Having thus described my invention, I claim 1. The combination with a steam boiler,
of a smoke stack formed with an annular series of cinder outlet ports in the lower por tion of the head section thereof, a cylindrical cinder jacket encircling the bodyof the stack proper and said cinder ports, cinder conducting and dlscharging means leadlng off from said jacket, and a perforated cinder breaker with deflecting ribs on its bottom face, supported in the stackabove said cinder ports, a steam exhaust nozzle in the base of the smoke box, and a telescoping petticoat, the upper section of which is stationary and supported with its top-edge'below the I bottom of the stack to allow for oversdraft, and the lower section of which is adjustable in relation to thesteam exhaust nozzle to vary the area of the inlet zone of the petticoat. i T
2. The combination with a steam boiler. of a smoke stack formed with an annular series of cinder outlet ports in the lower portion of the head section'thereof, a cylindrical cinder jacket encircling the body. of the stack proper and said cinder ports, cinder conducting and discharging means leading off from said jacket, and a perforated cinder' breaker with deflecting ribs on. itsbottom face, supported in the stack above said cin der ports, a steam exhaust nozzle in the base ofthe smoke box, and a telescoping petticoat, the upper section of which is stationaryand supported with its top edge below the bottom of the stack to allow for overdraft, and the lower section of which isadjustable infrelation to-the steam exhaust nozzle to vary the area of the inlet zone of the p'ettic-oat, and means controlled exter nally of the stackfor raisingand lowering such petticoat pipe and sustaining the same at different elevations.

In testimony whereof I afiix my signature.
