Applicationflm November '17, 191-1. Serial No. 660,809."

To all whom it may concern:

Be' known that I, NICKoLAs J. ROETHER, citizen of, the United States, residing at Mineral Point, in .the county of Iowa and State of \Visconsin, have invented, certain new and useful Improvements in Spark Arresters; andI do hereby declare. the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains'to make and use the same.

This inventionrelates to spark arresters and more particularly to that class of spark arrest'ers adapted for use upon smoke stacks of engines;

' An" object of the'invention is to provide a.

spark arrester attachment for smoke stacks which will eiiectively arrest the sparks and prevent escape of the same.

Another object is to devise a spark arrester of this character which may be readily positioned upon. the upper end of a smoke stack and which will allow the escape of the smoke, but will prevent the sparks or cinders from escaping and probably causing serious damage.

Another object. is to devise a spark. arrester of novel form and one which will be extremely effective .in the performance of its duties;

Other objects and advantages will be herein after set forth and pointed out in-the specification and claim.

In the accompanying drawings whichare maKe a part oi this a plication, Figure 1,- is a vertical sectional view through the spark arrester secured upon the upper' end of a smoke stack, said view being taken on the line 1-1, Fig. 2, while, Fig. 2, is a similar view,- at right angles to Fig. 1, taken on the line 2-2, Fig. 1.

Referring more particularly to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 r restnts the upper end ofan ordinary smok stack over which the inverted V-shaped bottom 2 of'the spark arrest'ei; housing is secured, a suitable opening being provided through the center of the bottom 2 to accommodate the smoke stack 1,} said stack projecting slightly throughd: the bottom 2. The bottom 2 is, preferably made rigid with the upper end of the smoke stack 1 and may, if desired, be formed integral therewith.

The side edges of the converging walls closed by screens. This willprevent any shown at of the inverted V shaped bottom 2 are con;

nected to the opposite sides 3 of the spark arrester casing. The lower edges of the slanting portions of the inverted- V-shaped bottom 2, however, are directed downwardly as shown at 4, adjacent the smoke stack 1, to meet thehorizontalportions 5, some distance below the upper end of the smoke stack. Connecting with the horizontal portlons 5, opposite the portions 4:, are the lower edges of the sides 6, positioned at.-

.right angles to and' connecting with the sides 3, above the smoke stack 1. Depending, from thelower horizontal portion 5 are th e'pipes 7, beneath which buckets or other suitable means may be placed to catch soot and the like collected between the walls 4 and 6,' it being understood that the valve plates 8, resting upon the horizontal portion 6 are drawn outwardly to allow the 'soot to pass downwardly through the pipesff.

The upper end of the casing is closed by a cover or top 9 secured upon the upper edges of the

sides

3 and 6, and depending from the edges of a central opening in the top 9 is a screen 10 which is preferably wedge shaped and has its opposite ends 10 sparks or .cinders, reaching the upper end of the casing, from escaping through the central opening therethrough.

Projecting 'nwardly and downwardly from the inner surface of the side 6, near the upper ends thereof, are the deflecting plates 11. p

The sides 6 may be sloped inwardly, as 6, near their upper ends, if de shed, and the edges of the sides 3, below the invented V- haped central portion 2 of the bottom of the casing, may be converged slightly,"as shown at 3', toward the lower horizontal portions 5, upon opposite sides of the smoke stack. s Above the smoke stack 1 are the the oppositely disposed hollow cone members 12 and '13, the bases of said cones being disposed in a horizontal plane and-secured together by the'flan es 12' and 13' respectively. The point 0 the inverted cone 13 extends into the upper end of the smoke stack 1 and is supported in position by means o"f'the supportiiig straps 14, having their opposite ends Bent and secured to the cone 13 and to the interior of the smoke stack 1, adjacent the u per edge of the latter. Directed putwar y and upwardly from opposite sided of and secured to the upper cone 12 are the baflle plates 15 which are bent to dispose one portion at an angle to the other and convergingupwardly. The plates 15 are connected attheir lower portions and upon'opposite sides of the cone l2'by the integral portion 16; V

Thus it will be seen that when this an rester is in use, smoke, sparks and cinders pass out of the upper end of the smoke stack 1' and are guided by the lower cone 13 against the baflle plates 15 which will serve to retard the'same and deflect the sparks and Cinders and causethem to drop'between the plates 11 are directed any Clnd61:S'3.II'8St8dthereby will readily-slide offof said plates and drop downwardly upon the valve plates 8. The smoke will continue upwardly through the casing and travel outthrough the screens 10, which will also serve to prevent any small cinders orsparks, which may succeed in passing the-bafile plates 15 and deflecting plates 11', from escaping through d the upper end of the. device.

Itwillthus be'seen, that, by usingthis spark arrester, the sparks and-cinders traveling upwardly through the Smokestack will be prevented from escaping to the atmosphere and probably causing a. the or other serious'damage. It will-also be evident that,

asothe lower portions of the casing,between the portions 4 and side walls '6 and 3, are filled with cinders'an-d soot, suitable receptacles may be placedbeneat-h the pipe 7 and the valve plates 8 withdrawn to allow the. cinders and soot to drop downwardly through the pipe 7 and into the receptacle, thus cleaning the casing. It'w'ill also be evident that this spark arrester may he employed iilipon any smoke stack and will be highly e cient and efiective in the performance of its duties;

Owing to the extremely smallnumber of parts and the comparatively simple formation thereof, it will be evident that the spark arrester-may be manufactured at areasonable cost and will be, subs'tantial'in use.

- What I claim is:'-

A spark arrester comprising the combina-- tionwith asmoke stack, oppositely disposed cone membershavin'g their bases secured together and disposed in a horizontal plane,

and baflle plates secured to the .upper of said cones and disposed upwardly and outwardly therefrom; of a'casi-ng secured over the-upper end of the smoke stack, said casing having a screened openingin the upper portion thereof and deflecting plates nearits upper end, said casing depending" below the upper end of the smoke; stack and upon opposite sides of the latter, an inverted V-shaped bottom disposed between said de-.

pending portions' and provided with a circularopening 'for' receiving said, smoke stack, pipes projecting from said dependingportions, valve plates within said depending g portions to cover the open'upper ends of 'p p v In testimony whereof I have signed tiny name to this specification thepresenc e of two subscribing witnesses.
