Specification of Letters Patent. Patented. March10, 1908 Application filed May 23, 1906. Serial 110,318,878,
To all whom it may concern: 7
Be it known that I, Lewis H. STARRETT, a native of the Dominion of Canada, residing at Portland, in the county of Multnomah and State of Oregon, have invented new and useful Improvements in Spark Arresters, of which thefollowing is a specification.
This invention relates to spark arresters,
'- designed especially for use on the stacks of locomotive portable and stationary boilers, and has for its objects to produce a comparatively simple, inexpensive device of this character which may be inexpensively in stalled, one whereby the sparks will be eflectually arrested and precipitated into the spark receptacle, one wherein the, hood may be adjusted as circumstances require, and one in which the receptacle may be conveniently drained and cleaned.
With these and other objects in view, the invention comprises the novel features of construction and combination of parts more fully hereinafter described. I
In the accompanying drawings, there is shown a central vertical section taken longitudinally through the smoke stack equipped witha spark arrester embodying the invention.
' Referrin jto the drawings, 1 designates a smoke stac duct on which is fixed a hollow drum or receptacle 2 comprising prefer-' ably an inverted" truncated cone secured to the duct and a truncated cone supported on the up er endof the other andhaving a tubular is'c'harge mouth or duct 3 of greater diameter "than and centered above the discharge e-nd of the stack -1 wh ich projects into the lower on d of and'extends substantially half the distance through-the vessel 2 to form' thereina central, tubular shell or core 4; forming a continuance. of astack, it being noted that the upper duct 3 projects at its lower end as at-5 into the receptacle 2 for a purpose whichwill hereinafter appear. A,
"Arranged over the upper open end of the stack 1 within the drum 2 is an arched spark arresting member or hood 6 fixed upon the upper ends ofsa plurality of vertically de: pending engaging members or arms 7 which are yieldable laterall' and slidably engage the internal surface 0 the stack for-retaining the hood in position thereon; there being extended into the drum through an opening 8 in the upper cone an adjusting lever 9 pivoted between its ends in a suitable bearing 10 outside the cone and at its inner end as v 11 to the hood 6, saidlever having engaged with its-outer end a depending traction'ele- .ment or chain 12 extended through a suitable guide 13 and carried to a point for convenient operation by the engineer to effect a vertical adjustment of the hood 6, which is provided with a cylindrical, vertically depending flange or rim 14 and with a central,
depending conical deflecting .portion 15. The lever is adapted to strike the lower edge of the upper duct 3 for limiting the upward movement of the hood.
Entering one side wall of the drum 2 and v in a plane beneath that of the upper end of the core 4 is a feed pipe 16 adapted for supplying water to the receptacle which is pro-v vided with an overflow pipe 17 entering the wall of the drum at a point slightly below the oint of entrance of the i e 16 and at the ine of the desired level 0 ,t' e water 18 contained within the vessel which has at a point adjacent the juncture of its lower end with the stack a draW-ofl valve or cook 19.
In practice, the sparks passing u Ward through the stack-1 with the smoke wil come in contact with the hood for precipitation into theli uid 18 within'the receptacle, it 1 being note that in the'action of arresting the sparks the central conical portion 15 of the hood serves to throw the sparks outward while the depending flange 14 with which they come in contact causes their positive precipitation into the underlying liquid. -When desired, tliehood may be lifted vertically in effecting its adjustment toward and from the upper portion of the stack by downward tractlon on the element 13, it being a {parent i that by slacking the ,element t e weight of the hood 6 will carry the'same automatically downward toward the mouth of the stack. It is apparent that an sparks which may esca e from the hood wil contact with the inward y projecting portion 5'of the dischargetube and be arrested thereby for precipitation into the liquid.
- Having thus described my invention, what I claim is:
In a spark arrester, the combination of a smokeduct, an inverted truncated cone secured around the upper portion of the duct to constitute with the latter a water containing receptacle, a truncated cone resting on and secured to the upper end of the first cone and provided with an opening in its wall, a
' into the 15p duct arranged-in axial alinement with and of greater diameter "than the smoke duct and extending at its lower end a suitable distance intothe upper cone,'a hood disposed in the up er cone and- .rovided with a de ending cy indrical rim, exible vertical mem I cured at their up er ends to the under side of the hood and s i ably engaging the internal surface of thelower duct, a lever extending er cone through the o ening thereof an ingfidly connected with t e top of the hood, a crum for the lever located ment of the outside the upper cone and arranged to permit the lever to strike the lower end of the upper duct for limiting the upward movehood, and means connecting with the lever for actuating the same.
In testimony whereof I ah'ix my signature in presence of two witnesses.
