DISTRIBUTOR HEAD‘ FOR ST‘OKERS
Charles A. Binney, Hornell, N. Y., assignor, by
mesne assignments to rl.“he Standard Stoker
Company, Inc., (1922), New York, N. Y., a cor
poration of Delaware
Application November 9, 1935, Serial No. 49,006
7 Claims.
My invention relates to stokers of the scatter
feed type, and more particularly to that type
wherein the fuel is introduced into the ?rebox
and then projected over the ?rebed by means. of
pressure?uid jets issuing from a chambered dis
tributor head disposed within the ?rebox.
It is an object of my invention to improve the
distributor head used in stokers of the above type
by constructing that portion of the head contain
ing the jet ori?ces as a member which is sepa
rable from that portion thereof into which the
pressure ?uid supply lines are secured.
Asa further object, my invention contemplates
the above improvements in stoker distributor
heads to the end that the portion of the head
which contains the jet ori?ces may be replaced
without disconnecting the pressure ?uid supply
lines from the distributor head.
It is also an object of my invention to improve
)20 the construction of the distributor head whereby
the connection of the supply leads thereto is
greatly facilitated.
Various other objects and advantages of my
invention will appear from the following de
scription thereof taken in connection with the
accompanying drawing which illustrates my in
vention adapted to a locomotive stoker of a well
bracket 9. Upon the upwardly directed portion
of the elbow conduit 2| an upright conduit 22 is
seatedand it extends upwardly into the ?rebox
to a point above the level of the grate and with
its rear wall 241 disposed adjacent but spaced >10 ,
from the inner sheet 18 of the water leg lcl. A
protective grate 25, which is mounted upon the
grate bearer 26, surrounds the forward and lat
eral sides of the upright conduit 22.
Fuel is conveyed through the stoker by means ‘
of a conveyor screw 21, the forward end of which 15
terminates within the elbow conduit 2! and forces
the .fuel upwardly through the upright conduit
22.
As the fuel emerges from the discharge
mouth 28 of the upright conduit 22, it is pro“ \
pelled forwardly into the ?rebox by blasts of 20
pressure fluid issuing from the distributor head

tion;
3i! and the rear wall 24 of the upright conduit,
rigidly secure the base 31 to the conduit 31%.‘ Ex
tending forwardly from the ?ange it is a pro-. 35
jection ‘l, V-shaped in transverse cross section
and arranged with the crest thereof directed

On this drawing,
Fig. 1 is a side elevation, partly in section, of
‘the forward end of a locomotive stoker illus

is indicated at S and includes an elbow 2|! which
passes beneath the rear water leg M of the
boiler and thence is directed upwardly toward the
?rebox 12. The elbow conduit 2| is rigidly car
ried by the locomotive frame 1! on a support
at the rear of the rising column of fuel, is novel
in construction and in its relation with asso
ciated parts of the stoker mechanism as will 25
hereinafter appear.
At its uppermost portion, the rear wall 211 of
the upright conduit 22 is provided with a recess
or indentation 29 on its inner side to receive a .30
?ange 30 of the base 3!, the former and latter
forming an integral portion of the distributor
known type.

tributor head illustrated in Fig. 1;

.
Referring to the drawing, and primarily to Fig.
1, L indicates a_locomotive having a boiler 10
45 ‘mounted above the frame ll. ‘ The boiler in
cludes a ?rebox l2, provided with a grate 13
which extends forwardly from the rear water leg
M of the boiler. An opening l5 for manual ?r
ing and entry into the ?rebox I2 is formed by
50 the ‘inner and outer sheets I6 and I1, respec
tively, of the rear water leg 14. This opening is
disposed above the level of the deck l8 of the
locomotive cab and is closed by the usual ?re
, door 20.
The stoker for delivering fuel into the ?rebox
Bolts 32, passing through the‘ ?ange
downwardly toward the fuel rising through the
upright conduit. A thin triangular-shaped rib
33 connects the crest of the projection, l ‘with
‘the ?ange 30, the rib 33 and V-shaped projec
tion being related so as to offer little, if any,
resistance to the upward movement of fuel.
The upper edge 34 of the projection l’ is
smooth and extends rearwardly to the plane of
the rear side of the ?ange 30. Extending in‘a
rearward direction from the aforesaid plane of
the ?ange 39 and formed integrally therewith
is a sector-shaped hood 35 in which are formed 50
two rows of passages 36 and 31. Each passage
36, 31 is provided at its lower end with a threaded
opening 36a, 31a, respectively, and opens for
wardly at its upper end through the face 38
which is perpendicular to the plane of the upper
2
2,121,313
edge 34 and is likewise smoothly ?nished.
At
each side of the sector-shaped hood 35 is a flange
39, the inner surface of which is ?ush with the
smoothly ?nished face 38.
A chambered head 40 is seated upon the base 31
between the face 38 and the upper edge 34 of
the base 3|. The head 40 has a smooth bottom
surface 4| which seats upon the upper edge 34
of the base 3|. At its rear side, the head 45 is
livery end thereof, means formed with said base
member providing a plurality of pressure ?uid
passages, each of said passages having an in
take opening within said ?rebox, a head remov
ably secured to said base member, said head in
cluding a plurality of chambers each being pro
vided at one side with a pressure ?uid intake
opening, each chamber being arranged for the
discharge of pressure ?uid at a point remote from
10 provided with a smooth face 42 and a ?ange 43
its intake opening, each chamber of said head 10
at each side of the head arranged with the outer
surface thereof ?ush with the face 42. The head
40 is provided with two rows of chambers 44, 45,
each of which at its rearward end opens through
the face 42 and is arranged to register with a
respective passage 36 or 31 of the sector-shaped
hood. A gasket 46 is interposed between the
faces 38, 42 to form an effective joint when the
bolts 41 which pass through ?anges 39, 43 are
20 drawn tightly.
Each upper chamber 44 is provided at its
forward end with forwardly directed jet ori?ces
at its intake opening arranged to register with
such as 53, while the lower chambers 45 are each
provided with laterally directed jet ori?ces 5|.
Pressure ?uid issuing from these jet ori?ces 50,
5! acts upon the fuel core rising through the up
right conduit 22 and projects it forwardly and
laterally into the ?rebox.
Pressure ?uid is con
ducted to the chambers 44, 45 by pipes such as
30 52 which are threaded into the openings 36a,
31a of the hood 35. The pipes 52 extend down
wardly from the distributor head D between the
inner sheet N5 of the water leg ill and the rear
wall 24 of the upright conduit 22 and thence
35 curve downwardly beneath the mud ring 8 of
the ?rebox. At their upper rearward ends, the
pipes 52 are connected to a pressure ?uid re
ceiving manifold 53, the latter being provided
with suitable valves 54 for independently con“
40 trolling the pressure of ?uid in the respective
pipes. In order to facilitate its connection with
the manifold 53 and the distributor head D, each
pipe 52 is provided with a pair of unions 55, one
of which is within the ?rebox l2 and the other
46 of which is exterior of the ?rebox.
Those familiar with the art will readily under
stand that by the invention embodied herein,
the chambered head 43 may be replaced when
the occasion demands, by removing the bolts 13‘!
50 which become accessible to a mechanic upon
opening of the ?redoor 20. Upon removal of the
bolts 41’, the chambered head 40 is removed and
replaced by a new one.
This is accomplished
without the necessity of disconnecting pipes
55 within the ?rebox. Prior to this invention it
has been necessary to disconnect the pressure
?uid supply pipes from the distributor head be
fore the latter could be removed. Since this
could only be done after the ?rebox has cooled
60 su?iciently for entry thereinto, the locomotive
wasremoved from service. By the present in
vention, the pipe connections between the mani
fold 53 and the distributor head D are disturbed
only when major repairs to the stoker are neces
65 sary, such as the repair or renewal of the up
right conduit 22.
