‘
gteferring to the drawings, a locomotive is in
dicated generally by the letter A and a tender
by B, the two being connected by a coupling C
to permit articulation therebetween. ‘
'
The locomotive A is provided with a boiler ?re
thereby providing for universal movement be
tween the conduit and nozzle. The conduit 26 40
is provided at its lower end with rollers 30
mounted on the bearings 14, preferably formed
integral with the lower end of the transfer con
duit 26. The rollers 30 are movable along the
tracks 3| of the tender frame ll to permit fore 45
and aft movement of the transfer conduit 26 with
respect to the tender as relative longitudinal
movement between the locomotive and tender
occurs.
The lower portion 32 of the conduit 26 is hop 50
per-like in construction. having diverging side
walls 33 and 34, an upright front wall 35, and a
rear wall 36 having an upright lower portion 31
and a rearwardly inclined upper portion 38. For
ward of the front wall 35, the hopper 32 is pro
2

vided with an integral trough extension 38, an
opening 58 in the front wall 35 providing com
munication between the hopper 32 and the ex
tension 38. ' A tubular member 5| constitutes the
of the angle bars 58. The bottom wall 53 of the
chute extends downwardly and forwardly from
the rear slope sheet 22 of the bin over the in
clined upper ,wall portion 38 of the hopper 32.

pered portion of the side walls of the spout 51,
'
A single screw conveyor 82 is mounted in the
transfer conduit 25 and terminates at its forward
10 end within the nozzle 21, making substantially
a direct delivery of fuel from the hopper 32 to
the distributing mechanism ,53. The substan
tially straight delivery avoids any sharp turns or
angles which wouldtend to cause impacting of
15 the fuel and consequent undesirable crushing of
the fuel and permits the use of a single continu
ous screw conveyor, thus obviating the use of
universal joints in the screw conveying system
which also tend to cause undesirable crushing
7
20 of the fuel.
The screw conveyor - 52 is driven from its rear
ward end by a motor 54, mounted on the locomo
tive frame 45. The motor shaft 55 is universally
connected to’ a shaft 51 comprising telescopical
25 ly related sections 88 and 58, which in turn is
universally connected with ‘a shaft 58 journaled
in_ a bracket 5|, mounted on the conduit 25. The
shaft 58 is universally connected with a shaft
52, journaled in the gear casing 53, and gearing
30 54 operatively connects the shaft 52 with the
shaft 55, which inturn is connected with the
screw conveyor 52.

-
In the practical application to a locomoti
and tender of a stoker having a straight inclined
transfer conduit delivering fuel from the tender
to the firing opening, as best shown in Figures
1 and 3, it is clear that the transfer conduit can
extend rearwardly into the tender a limited dis
tance only. It is desirable, however, to have the
opening in the fuel bin floor extend to the rear
ward end of the bin to make the entire bin avail
able for stoker ?ring of .fuel. In the patent to
Fahnestock 1,792,216 the fuel must be conveyed
forwardly from beneath the rear of the bin to the
hopper of the transfer conveyor by another eon
veyor. Such added conveying means is obviated
in the present construction, and fuel is delivered
by gravity from all parts of the bin directly to
the hopper 32 of the transfer conduit 25. Elimi
nation of added conveying means provides addi
tional water space without in any way limiting
the coal carrying space. In applicant’s novel
construction a shorter section of the screw‘ is re
ceiving coal from the fuel bin, thus less power is
55 required to operate the stoker.
'
Angle bars 55 are secured to the under side of
the bin floor 23 and extend longitudinally along
the opposite sides of the opening 28. Secured
to the inner sides of the angle bars 55 is a spout
51 embracing the opening 25, having a sloping
front wall 58 and side walls 58 and 50. The side
walls 58 and Gil extend downwardly a greater
distance near the front wall 58 and taper off to
ward the rear of the bin. The height of the front
and side walls 58, 58 and 581s of course limited
so that sufficient clearance is provided to permit
pulling the transfer conduit 25 out of the tender
or inserting it therein through the front end
thereof.
70
.
,
In order to permit the fuel in the rearward
portion of the bin to fall by gravity into the
hopper of the transfer conduit, a chute 5| is pro
vided. The chute 5| is pivotally mounted at its
rearward end subjacent the rearward end of the
75 bin ?oor on pins 52 secured in the outer sides
so that the chute can be raised about its pivotal
connection to telescope the rearward portion of
the spout 51.
10
-
A spout 85 is pivotally mounted on a bar 51 ex
tending transversely of and secured to the for
ward ends of the angle bars 55. The spout 55
has a front wall 58 fitting within the hopper 32
and outside of the front wall of the spout 51. 15
The side walls 58 and 18 of the spout 55 fit outside
of and telescope the front end of the chute 5|
and likewise ?t outside of and telescope the lower
edge of the forward portion of the side walls
of the spout 51. A bar 1| extends transversely 20
of and is secured to the extreme lower rearward
ends of the side walls 58 and 10 of the spout 55.
The lower rearward end of the spout 55 rests on
the inclined wall portion 38 of the hopper 32 and
is free to move therealong as longitudinal move
25
ment of the transfer conduit with respect to the
tender occurs. ‘The lower end of the chute 5|
rests on the bar 1| permitting the chute 5| to
slide within the 'spout 55. The motion of the
hopper, it will be seen, causes movement of the 30
pivotally mounted chute 5|, since the latter is
supported ‘at its end
opposite its pivotally
mounted end on the inclined wall portion 38 of
the hopper 32, thereby keeping the fuel agitated
which will cause it to be fed onto the screw con
veyor 52 more uniformly.
35.
'
The spouts 51 and 55 and the chute 5| thus
form guides insuring the delivery of all the fuel
to the hopper 32. The pivotal-connections of
the spout 55 and the chute 5| permit them to be 40
raised when the transfer conduit is either re
moved or placed in position in the tender. To
prevent the chute 5| and spout 55 from coming
apart and dropping down after the transfer con—
duit is removed, a slot 12 is provided in each of 45
the side walls 54 and 55 of the chute 5| arranged
to receive the pins 13 secured to the side walls 58
and 10 of the spout 55.
The lower. forward wall of the nozzle 21 is
provided with a slightly upturned transversely
extending rolled edge || | and the lower rearward
end of the distributing device 43 is provided with
an arcuate indentation “2 arranged to receive
the rolled edge “I, permitting partial rotation
of the distributing mechanism 43_ about a trans 55
verse horizontal axis. When the lock nuts 8|
are loosened, the distributing mechanism can
be rotated a distance corresponding to the length
of the arcuate slot 82 and adjusted to any one
of a number of positions and secured in that 60
position by tightening the lock nuts 8|. Thus the
trajectory of the propelled fuel particles can be
adjusted by increasing or decreasing the slope
of the distributing table.
,
The adjustable feature of the distributing 65
mechanism together with the short nozzle 43 and
its universal connection with the tubular con
duit 8| permits the stoker to be applied to any
backhead whether it be a sloping backhead, or
a straight backhead. Thus all parts of the 70
stoker can be made of uniform and standard con
struction with the exception of the tubular con
duit 5|, which can be conveniently and simply
made to required length.
