Specification of Letters Patent.
Patented Cet. 3ft, i916..
Application ledkT/[arch 6, 1916. Serial No. 82,454.Y
To all whom 'it may concern:
Be it known that I, RALPH ADAMS, a citi- Zen of the United States, residing in Falls City, in the county kof Polk and State of Cregon7 have invented certain new and useful Improvements in Spark-Arresters, of which the following is a specification. l
This invention relates to that class of spark arresters in which the smoke and vapors pass to the outlet of the furnace stack' through screens of wire cloth which serve to arrest the sparks and enable them to be delivered separately or apart from the smoke and vapors to a suitable receptacle or to the ground. y
The object of my invention is to provide a spark arrester of the kind referred to in which an extensive screen surface is afforded which will not unduly retard the draft, and whereby screens of small mesh may be employed. f Another object of the invention is to provide means for producing a strong draft through the fiues which will keep the screens clear of soot,4 etc. y
Another object is to provide means for regulating the draft so that when starting the fire, or first getting up steam7 a freer draft may be obtained.
My improvements are illustrated in the accompanying drawings in which,
Figure l is a view mainly in vertical central section but partly in elevation of a smoke stack with my improvements applied thereto. Fig. 2 is a similar view of a modification.
The hood A of the boiler is provided with a stack B having a reduced portion B hinged at b to the body of the stack and carrying an outlet-pipe B2 of reduced diameter. A frustum shaped screen C is mountedk in the lower portion of the stack and is preferably circular in cross-section, being wider at the bottom than at the top. lt is reinforced at its lower end where it is riveted or bolted to the hood A. The upper end of the screen carries a cap l), the outer edge of which is bolted or riveted to the upper edge f of the screen and it is formed with an annular spark-receiving chamber d. The central portion d of the cap is open and on one side the chamber d communicates with a pipe E leading to the ground or to a suitable recep tacle. This pipey is provided with a reticulated portion c which permits the escape of smoke and vapors but past which the the stack at it and connected at its outer end with an operating rod I by means of which the cone may be raised and lowered. J indicates an exhaust steam pipe from the engine delivering to the stack below the screens and K indicates a similar exhaust pipe delivering to the stack above the screens. Either one or both exhaust pipes may be used to create a strong draft through the stack.
lWhen the parts are in the position shown in Fig. l the products of combustion pass into the space between the inner and outer screens. Smoke and vapors pass through the sides of the outer screen and thence rise to the upper portion of the stack and pass out at the delivery end thereof. Smoke and vapors also pass through thek inner screen and continue up through the circular opene ing of the cap and pass out through the stack. The sparks are arrested by the screens and are received by the annular cap D, entering the chamber Z and passing out through the pipe E. Steam from the eX- haust pipe J passing upwardly through the screens creates a kstrong draft therein and causes the sparks, to be directed against the inclined surfaces of the screens. This has the effect of scraping or rasping the screens and keeping them clear of soot. Steam from the exhaust pipe K creates a draft above the screen and tends to produce a vacuum or a suction which promotes the draft. 1While I preferably use both exhaust pipes, only one of them need be employed.
When starting the fire, or when getting up steam, the inner screen cone F may be lowered so as to increase the draft. This may be done ty means of the rod l operating upon the lever H in such manner as to lower the screen F and permit the products of combustion to pass more freely out through the opening d of the cap. After this the rod l may be operated to draw the upper edge of the screen close to the edge of the cap. Any suitable means may be v employed for locking the rod l'. to hold the cone F in place.
ln Fig. 2 I, have shown a modification. In this case the stack A delivers to an enlarged upper portion B which is supported on the lower portion A by flanges M. l
The screen C is attached at its lower end to a. ring c which is supported on the flanges M. rllhe cap D is similar to that shown in Fig. l and communicates with a discharge pipe E like that before referred to. The inner cone F is also similar to that before described and it is operated in a similar way. ln this case the rod l is shown as being threaded at its lower end z' and carrying a nut z". The lower portion of the rod engages a stop plate These 'devices may be employed for holding the cone F in its closed position or permitting it to be lowered. riChe lower portion A of the stack is shown as being provided with openings a near its upper end over which are' arranged wings or deiectors a against which some of the sparks and vapors strike and are deflected through the openings a and Yrise to the outer portion of the screen'C. In this way the draft is (somewhat 'equali'z'ed My improvements maybe applied to locomotives, donkey engines, hoisting engines, traction engines, or vin 'fact Yall kinds 'of engines burning any fuel except oil. EXperience has Vde'i'm'mstrate'd that a's'park arrester constructed in accordance with my invention is most eiiicien't 'asY the draft Vcan be 'easily regulated, screens of line mesh may be employed so as to prevent 4the escape of v'sparks with the smoke, and the screens may passing upwardly between' the screens, a pipe connected with said cap for conducting sparks from the stack,a guide rod for the low r end of the cone, and means for raising and lowering the cone toward and away from the spark-receiving cap.
2. A spark arrester, comprising Va stack, a frustum-shaped screen within the stack, an inverted cone-shaped screen within the screen first mentioned, a spark-receiving cap above the' screens having an annular cham* ber for receiving sparks passing upwardly between the screens and which is open at bottom and has an inclined top wall, a dise charge pipe Yfor sparks connected with said annular chamber, a 'guide rod for the llower end of the cone, and means for raising and lowering Vthe cone rtoward and away from the spark-receiving cap. Y
3. A spark arrester, comprising a stack,a
frustum-shaped screen within the stack, an
inverted vcone-shaped vscreen "within the screen ii'rst mentioned, a Isparkire'ceiving cap above the screens for receiving sparks pass ing upwardly between the screens, a steam exhaust pipe deliverying below lsaid cone- -shaped screen, and 'a lsteam lexhaust pipe delii'ferin'g inthe 'stack above said screens.
i. A spark arrester, 'comprising a stack, a frustum-shaped screen within the stack, 'an inverted 'cone shaped screen v'within V.the
screen frstmentioned, a y'spark-r'ecei'ving cap above the screens having an annularfchamber for receiving sparks passing upwardly Y between the screens -and a centralopening above the tcp ofthe cone-shaped screen and which is 'of substantiallythe same diameter as the top ofthe cone'shaped screen, and
means lforraising and loweringv the coneshaped screen toward and away from said cap. p Y 'Y Y In testimony whereof, I have hereunto subscribed my name.
