SPARK ARRESIER.
Application filed January 13, 19,2621 Serial No. 80.897.
This invention relates to a spark arrester and is designed for use, more especially, with the steam boilers of locomotives, logging machines and other engines, operating in the woods, to prevent escaping sparks setting afire brush and other inflammable material.
The object of my invention is the pro vision of a spark arrester comprising apparatus whose parts are constructed and ar ranged to cause particles of mattei' issuing from a furnace stack to be doused in a body of water to quench the sparks and obviate accidental lires.
The invention, generally stated, consists in the employment upon a stack of an annular water containing pan in association with a plurality of nozzle stack-outlets through which smoke and other unconsumed particles 2o of matter are delivered as jets into the water to extinguish any fire or flames before escaping into the atmosphere.
The invention further consists in the novel construction, adaptation and Combination of es parts hereinafter described and claimed.
In the accompanying drawing,
Figure 1 is a perspective View of a portion of a steam boiler with a spark arrester embodying my invention applied thereto; Fig.
:i0 2 is a )lan view ot Fig. 1; and Fig. 3 is a View showing the boiler portion in elevation, and the spark arrester in vertical section on line 3-3 of Fig. 2.
In said drawing, the reference numeral 5 .1:5 represents a steam boiler having a stack 6.
' Formed integral with or secured to said stack, as by means of a clamping band 7, for example, is a stack pipe 8 constituting a prolongation of the boiler stack.
Said stack pipe 8 has an internal diameter approximating that of the stack 6. Pro vided upon the upper end of the stack pipe 8 is a hollow head 9 of an inverted truncated conoidal shape having a top wall 10.
Surrounding the stack pipe 8 is an annular Immediately above the chamber 16 the wall 10 of the head is provid-ed with a series of apertures 17 disposed in spaced a art circular relation concentric of the axis o the head 9.
Connected with the wall 10 at the respective apertures are the inlet ends of discharge nozzles 18, which nozzles consist of tubes bent upon themselves so that each will be provided with a leg 19 extending upwardly from the head 9 to a return. bend 20 and a downwardly directed leg 21 extending down outside or' the stack head into the pan 11 and terminating above the water surface therein. 22 represent straps embracing the legs 21 of the several nozzles and are secured to the outer wall 13 of the pan.
The axes of the return bend and the leg portions of each nozzle are located in a vertical plane disposed radially, or nearly so, with respect to the vertical axis of thel stack and the head 9.
The nozzle legs 21 which extend into the tank are, preferably, inclined inwardly or toward the stack axis, from the respective bends to their lower extremities.
By thus directing the outlet ends of the nozzles inwardly and having them terminate in the region between the water and the plane of the top of the pan, the delivery of combustion products from the stack is facilitated by winds or currents of air moving from any direction transversely of the device.
In practice the sum of the areas or cross sections of the nozzles should be less than the internal area or cross section of the stack thereby accelerating the passage of the smoke streams through the nozzles. Such increased speed of the smoke streams ensures their being delivered upon the water surface with such force that the heavier particles, at least, will be submerged in the water resulting in the quenching o'l' the sparks.
The smoke after being freed from sparks and heavy solid particles-which are caught is the water-escapes through the open top of the pan.
The construction and roperation of Vthe spark arrester will, it is thought, be understood from the foregoing description.
A spark arrester comprising, in combination, a smoke stack, an annular water-containing pan surrounding said stack, a head member connected to the upper end of the inverted U-shupe, one end of each tube being connected to the head :it the respective 10 aperture and the other ends of the respective tubes extending downwardly into Suid pan.
