anism for a stoker that is conveniently adjusted,
The invention is particularly adapted to stokers
without dismantling any part of the stoker or for use with locomotives and is so illustrated and
the ñrebox, and has for its main object the pro
lo interrupting its. operation, to distribute fuel in
an even bed over the firebox under all conditions
of firing.
A further object of the invention resides in the
provision of novel distributing mechanism where
I 15 in fuel may be continuouslyspread in a uniform
. blanket over the entirevfirebed by a primary fuel
distributing means and more or less fuel may be
distributed over one side or the other of the fire
bed by auxiliary means independently of the pri
20 mary distributing means. '
Another object of the invention resides in the
provision of a novel blast chamber member.
Other objects of the invention reside in the
provision in a Stoker of novel adjustable features
25 that cooperate and are so related as to effect new
and useful results.
With the -above and other objects and advan-tages in view, the invention consists in the fea
tures of construction, the combination of ele
30' ments and arrangement of parts hereinafter more
fully described and claimed.

In the drawings, the locomotive is designated
generally by the numeral I0 and is provided with 15
a main supporting frame II and a ñrebox I2.
The ñrebox I2 is provided with grates I3, a.
smoke arch I4 supported on the customary arch
tubes I5 and a backwall I6 having a firing _open
ing I1 therethrough. Flues I8 extend forwardly 20
from the ñue sheet I9 at the forward end of the
flrebox I2.V A suitable stoker, indicated as a
whole at 20, is provided for conveying the fuel
from a source of supply and delivering it to the
firing opening I1. _The part of the stoker mecha.- 25
nism illustrated comprises _a riser casing 2|, which
is at the forward en‘d of a series of conduit ele
ments leading from a source of supply, such as
the tender of a locomotive. One of this series
of conduit elements is shown at .22 and a conveyor
screw for advancing fuel therethrough is shown
at 23.

`
A housing 24 surmounts the riser casing 2| and
communicates with the firing opening I1. The
housing 24 is apertured opposite the ñring open
ing as at 25, through which aperture access may
be gained to the ñrebox and through which fuel
may be hand ñred. A ñredoor 26, of any suitable
type, is arranged to form a closure for the aper
ture 25.

4As the fuel emerges from the riser casing 2|
into the housing 24 it is projected forwardly
through the firing opening I1 into the firebox
by a pressure ñuid blast issuing from the blast
chamber casting'21, which casting is mounted in
the rear wall of the riser casing 2| at the rear
of the rising column of fuel. The blast chamber
casting 21 comprises a plate-like portion 28, over
lapping the inner marginal edges of an opening
29 in the rear wall of the casing 2|, and a hub
portion 30 passing freely through the opening 29.
A cover plate 3l is mounted on the hub portion
30 and is drawn up tightly against the shoulder
32 by screwing the valve body 33 on the threaded
portion 34 of the hub 30. The outer portion of 55
2
aioaeae
the cover plate 3l overlaps the outer marginal
edge of the opening in the rear wall of the cas
, ing 2l, thereby holding the blast chamber cast
ing 21 in contact with the rear wall of the casing
2l, yet permitting sliding movement of the cast
ing 21 along the rear wall of the casing 2i to any
desired position, limited only by the clearance be
tween the hub 30 and the 'marginal edge of the
opening 29.
10 _Adjustment of the blast chamber casting 21 in a
horizontal transverse path is effected by an ad
"
.
i '
ing with passage 68, which chamber has not been
shown in the drawings. Jet openings 62 directed
through the openings 5d are provided in the wall
of the jet casting 55 and communicate with the
chambers therein. It becomes apparent, there
fore, that by manipulating the handle 56 to ro
tate the jet casting 55, the trajectory of the
pressure ñuid blast issuing from the jets 62 may
be raised or lowered as desired.
The blast of fluid under pressure issuing from' 10
the jets 62 projects the fuel emerging from the
riser casing 2l forwardly through the firing open
ing and into the ñrebox in aerial paths. This
blast constitutes the primary means for projecting
justing screw 35. This screw 35 is threaded
through- a boss 35a. and carries a head 36 received
in the guide member 31 of the blast chamber cast
„ fuel into the _ñrebox. However, a portion of the 15
15 ing 21. Now, when the screw 35 is turned in one
fuel emerging from the riser casing is not struck
direction, the head 36 exerts pressure against the
wall 38 moving the blast chamber casting 21 hori
zontally in one direction; and when the screw is
by the blast issuing from the jets 62, but drops
over the front wall 63 of the riser casing 2i onto
turned in the opposite direction, the head 36 , the distributor plate 66.
exerts pressure against the slotted wall 39 moving
the blast chamber castinghorizontally in the- op
posite direction. The wall 39 is slotted vertically
and the guideway for the head 36 extends ver
tically through the guide member 31 so that the
25 blast chamber casting’may be adjusted vertically.
Vertical adjustment of the blast chamber 'cast
ing 21 is provided for by a pair of adjusting screws
40, each of which has a right-hand thread thread
Y ed in the flange 4l of the casing 2i and a left
30 hand thread threaded in a block 42 which is ar
ranged to slide horizontally in a groove 43 in the
valve body 33. Vice versa, the left-hand threads
may be threaded in the ñange 4l and the right
hand threads> may be, threaded in the block d2.
35 Rotation of the adjusting screws 40 in one di
rection will raise the blast chamber casting and
rotation in the opposite direction will lower it.'
As a resultant of the vertical and horizontal
transverse adjustability of the blast chamber
40 casting 21, it may be adjusted to any- position
limited only by the clearance between the hub 39
and the marginal edge of the opening 29. f
The sides of the blast chamber casting 21 are
chamfered, as at d'4, and its lower edge is cham
fered, as at 45, to permit the blast chamber to
be more easily adjusted when the casing 2i is
ñlled with fuel and also to prevent obstructing
the passage'of fuel through the casing.
The blast chamber casting 21 is provided with
50 passages 4B, 41 and d8, that extend through the
hub portion 30 into the valve body 33. Fluid
The distributor plate extends forwardly from. 20
adjacent the front Wall 63 of the casing 2l into
the ñring opening i1 and is keyed to a shaft 65
that extends transversely through its rearward
end portion. The ends of the shaft 65 extend be
yond the sides of the distributor plate and are ro
tatively mounted in the bearings 65 and 61 formed
in the opposite side walls of the housing 24. By
rotating the shaft 65, the distributor plate may be
made to assume any desired inclination from the
horizontal. To provide for convenient adjust 30
ment of the plate, one end of the shaft-65 carries
an arm 68 exteriorly of the housing 24, to which
movement is communicated by means including
a rod 10, attached at one end to the free end of
the arm 68, and at its other end having thread
ed thereon an adjusting wheel 69.
Fuel is projected from the plate 64 by a blast '
of fluid under pressure issuing from a distributor
head 1_I.
This distributor head comprises a jet Y
40
pipe 'i2 that extends vertically through the rear
ward central portion of the plate 9d and is pro
vided with jet openings 13 in that portion project
ing above the surface of the plate 64. A sta
tionary casing 1Q surrounds that portion of the
jet pipe 12 that extends above the plate 59 and is
provided with a slot 15, through which under nor
mal operating conditions a blast of ñuid under
pressure issues from the jet openings 13. Fluid
under pressure is supplied to the jet pipe 12 from
a suitable source by the supply pipe 16.
50
The jet pipe 12 is provided beneath the plate
63 with‘an arm 11, to the free end of which is
under pressure is supplied to the chamber ¿i9 in
the valve body 33 from a suitable source of supply flexibly attached a rod 18 that projects through

permanent nature,x mere adjustment of the jet
bers |02 and |03 disposed above the plate 64, one
at each side of the firing opening. Each of the
defiecting members |02 and |03 comprises an
’ elongated bar |04 and a flattened horizontal
blade portion |05 having a curvate forward edge
from which depends a curved skirt |06.
The deiiecting members |02 and | 03 are secured
at their rearward ends to the shafts |01 and |08,
respectively, mounted respectively in the blocks
|09 and ||0. Guideways ||| and ||2 are formed 20
in the opposite side walls of the housing 24 in
which the blocks |09 and ||0, respectively, are
arranged to slide vertically. The shafts |01 and
4|08 are journaled in the blocks |09 and H0, re
