9 claims. (014110-101) This invention relateszto stakers and more particularly to .improved means in :a stoker for dezdectingfuel.
It is an object of this invention .to provide in v a Stoker, :a deflector that is easily .and readily adjustable Vand capable of vdelecting fuel to any portion .of .the :fuel bed.
-Itzis mfurther object of this invention to provide a defiector mounted on .a pivotal .axis mov- 1o able transversely, the deflector .being arranged to `move about'said axis;
With these land other objects in View, 4which will become apparent vas the .description proceeds, the invention "resides in :the construction, combination .and .arrangement of parts, hereinafter moretfully .described and claimed, .and illustrated inthe accompanying drawings, in which Fig, 1 isla partial lvertical longitudinal .section ofthe stokerand .a portion of :the locomotive with the invention :in place;
Fig. i2 is .a plan view of the structure shown in Eig. r1; and
Eig.3 isfa vertical `section fon :the 'line 3--13 of In Ithe figures, III :designates :a boiler iirebox of conventional .designhaving ,a .backhead I I `with a :firing opening .=I2,.and provided withthe grate I3. Fuel is delivered to the rebox byV suitable stokerimechanism, only so vmuch beingshown as is Vnecessaryto a complete understanding of this invention.
The forward `tubular conduit section orriser Aof' .a flexible conduit .system .extending from' a source of Vfuel supply, .as the bin of sa'locomotive tender, to the firing opening I12 .of .the boiler is designated as I4. lThe riser :I4 is carried from the backhead fl .I by a supportingbracket 115. 'The riser terminates at its lower l.end in a spherical 'seat IE receiving .the ball member yII of a conduit section I8 leading forwardly from a source of fuel supply.
From :its lower end the :riser .extends zupwardly and forwardly, daring .outwardly .at its vupper end, :and communicates with the-'ring opening :I2 :through its 'laterally .spreading and substantially horizontal mouth portion I9. vThe mouth portion I9 is provided with .the flanges 52.0, :20a for attachment to .the sbackhead by suitable fastening means, as by bolts. 'This Imouth portion is formed with an upstanding wall 2l to ywhich is detachably tmounted .a .distributor plate 22, and forms :an .extended door portion of `the riser projecting'fthroughtheiiring opening fI.2 ofthe back- Ihead. The `riser 214 is .provided with an `,opening .'23 through which access .may .be fhad Yto ithe interior thereof. A cover 24 is provided for the opening 23. 'I'his cover is hinged at its upper end at 24a `to the riser I4 and is held in closed position by a latch v25. Rearwardly of the distributor plate 2-2 and outside of the firebox is a vertically 5V disposed nozzle or distributor head 26 to which pressure fluid such as steam is supplied by a desired number of supply 4pipes 21. The nozzle 2,6
is provided with openings 28 in horizontal alignment for emitting a fan-.shaped blast of `fluid 10 across the distributor plate. .l
Disposed in the conduit section I8 is a screw 29, preferably formed with'an additional ilight at its vforward end to assist in insuring a continuous stream of fuel.
In stoking devices of the character described and illustrated in the drawings, it has been found in practice that the screw means has a tendency .to discharge more fuel to one side of the riser than to the otherand in turn the fuel stream de- 0 liveredon to the steam blast is of unequal volume and more fuel is spread over one side of the rebox than the other, establishing troublesome iire conditions. The side to which more fuel is delivered depends -upon the direction of rotation 25 of Vthe screw means .and whether it is a left or right hand screw. f
This invention provides novel means to vovercome this uneven delivery and distribution l,of fuel comprising the deflector member 3-I pro- 30 vided with the vane 32 pivotally mounted in the upper portion of the riser I4 and arranged to :be-movable transversely of the riser I4 as hereinafter described. The `upper portion of the riser cover 24 is provided with a rectangular 35 slot or opening 33 forming a guide for the transverse movement of4 the defiector 3I.V The de- ;lector vane 32 depends in a; perpendicular position from its shaft portion 34. The shaft 34 extends up through the rectangular opening 33, 40 a handle 35 being securely fastened to the top of said shaft and arranged to give movement to the deflector vane 32 to any desired degree of deflection about its shaft 34 as an axis.- The -angular Vadjustment or the degree of deiiecton of 45 the deilector about the shaft 34 is regulated independently of the transverse movement of the deflector in the riser by moving the handle 35 to the right or left. The delector may therefore, be given an angular adjustment from any one 50 of its positions in the riser.
The deflector 3I and the handle 35 are supported from :the transversely movable plate 36, the top portion of which is designed to conform Withthe contour of the riser cover 24. The sides of the plate 36 are provided with the recesses 31 to permit the transverse movement of the plate. The lower end of the plate 36 is provided with the quadrant 38 for locking the deector handle in a predetermined position, the latter being provided with a suitable locking latch 39 to engage in the teeth of the quadrant. The portion 40 of the shaft 34 to which the handle 35 is attached is formed angularly to prevent movement of the deflector about its axis when the the handle is in fixed position. The upper end of the shaft 34 is threaded as at 4I and a nut 42 holds the deflector in place.
The shaft 43 supported in the bearings 44 and 45 and havng a threaded portion`46, extends transversely of the riser between the riser cover 24 and the plate 36. A threaded block, 41 on the threaded portion 46 of the shaft 43 engages l a slot 48 in the top portion of the plate 36. The shaft 43 is operated by means of the hand wheel 49. Turning the hand wheel 49 revolves the screwV 46 in the block 41, the block 41 as it moves along the screw 46 carries the plate 36 with it, which in turn moves the deector 3|. A few turns in either direction will move the deiiector to either the right or extreme left position. No appreciable effort is required to turn the hand wheel which can be readily adjusted during the time that the stoker is in operation or while the stoker is at rest. The deflector responds to the slightest movement of the hand wheel giving the fireman the finest possible adjustment and maintains it at the desired point. Moving the plate 36 by means of the hand wheel does not in any Way interfere with the original setting of the de- ,flector or deector handle locking device.
' If banks of fuel are formed on the left side, right side or center of the firebox, theyk can be burned away and therfire leveled out by so adjusting the deflector as to starve the banked side andY feed more coal tothe opposite side, the same being true of the center. Thus if it is desired to starve the left side of the firebox, the 'hand wheel is turned to move the deector nearer the left side wall of the riser conduit and the deflector blade is adjusted at an angle to the left sidewall by moving the handle to the left side of the quadrant. The amount of fuel fed to the left side being determined by the proximity of the rearward edge -of the deector vane to the left side wall of the riser. The closer the rearward edge of the deflector blade is to the riser left side wall the less fuel is fed to the left side of the firebox. Similarly banks may be removed from other parts of the iirebox.
Mynew deflector permits of a wider range of adjustments to positively insure a more even distribution resulting in a perfectly level fuel bed, higher rebox temperature, reduction in black smoke and instantaneouslyadjustable to quickly overcome banks in the rebed in any portion` of the firebox.
It is apparent my new deiiector has the advantage over types of deflectors now in use in that the fireman can set thefluid pressure distributor jets at a suitable pressure permitting them to spread the coal uniformly and then compensate for any unevenness in the firebed by adjustment of the deflector Without resorting to changing the pressure of any of the jets. This greatly simplifies the duties of the fireman.
