This invention relates to, lioppers, end__more
particularly to hoppers ‘employed
:boiler 'fiur
naces having in lconjunction `therewith :troughs
into which the Water for quenching the `azslamay
drain. In hoppers io‘fçgthis 'character it frequently
happens :that considerable. refuse enters :the
trough from the llfiopper Kwith the watencansing
the outlet discharge .df the trough to fclog. When
this occurs Athe nwater hows Aover the *wallsof the
trough and spills onto ¿the :door therebeneath.
In -order lto receive lthe fwater :draining lfrom the
hopper land to Tconserve space, `the trough must
necessarily be _positioned in lclose proximity to the
hopper and-because _o'f this :it is lditiicult ’to re
move the refuse collected -therein. ;. =

The _primaryfobject of the present invention.
therefore, is fto provide means whereby the trough
may bedumpe'd at intervals :so »that any .foreign
matter -collected ytherein will be discharged there
,A more vspeciñc object of r .the> present invention
is <to provide novel mechanism tomdumping the
trough, which -functions independently of operat
:Other and `further"objects will become appar

The hopper I shown herein is of the general
type disclosed in United States application Serial
No. 282,776, filed June 4, 1928, and comprises side
walls 2 and 3, and end walls 4 and 5. Hopper I
may be secured to the walls of an ash pit so that
the ashes discharging from the furnace may enter
vthe same by gravity. The bottom opening of the
hopper is normally closedby a pair of swinging
gates 6 and 1, the side supporting members 8 and
9 of which are pivotally supported upon pins I8
and II secured to brackets I2 and I3 provided
on the end walls 4 and 5 respectively. The side
supporting members 8 and 9 are provided with
50 intermeshing segmental gear members I4 and I5.
The lower edge of each gate 6 is provided with a
tooth section I6 which meshes with a gear I1 se
cured to a shaft I8 extending lengthwise of the
hopper. Shaft I8 is suitably journalled in brack
ets I9 secured to and extending outwardly from
end Walls '4,and 5. l'I'he supporting .members 8
and :9 ¿for the fgates ~6 andY :l :are respectively pro
vided avi-th enlarged >openings 23 and ‘2 I, thus 4per
mitting swinging-movement of the gates. From
the construction -of the 'elements-just described,

itis seen that upon vactuation of shaft I 8, gears Il
will -simuiltaneottslyswingthe-gate members S and
’l in opposite ‘directions’ about pins I8 and I-I.A
A bridge `member 22'secured to v4end'walls '4 and
5 near the lower ledges thereofgsubstantiaßlly mid- l0 ‘
wayfbe'tween'side walls 2 and 3, .is provided to de
ñectuthe 'ash from a »trough 24 supported there
beneath 4when the gates `6 'and `-I are opened.
shown .in'Fig~ 3, the inner edges of gates Ai5 and l
are spaced apart forming a drain for 'the hopper. l5
Asl'stated, ttide-‘bridge 2.2 is'provided to deflect 'the
ash from(- gtncmgh 24 “and thus. prevent Idamage
thereto.- It is apparent., however; that the trough
may ‘be »constructed 'snñîiciently'> rugged Áas not to
ing mechanisms for the hopper gates. ` -
be damaged by failing ash, and in such construc 20
tions the bridge 22 may beeliminated. 'Trough
24 has »securedto the 'end-s thereof pins 25 and 25,
respectively, which .extend through apertures pro
vided in brackets E21? and 28, secured, respectively,
to end walls 4‘and'5. 'Secured to pin 25 is a 'gear
Sßvvhich ¿meshes with a segmental gear 3| rotat
ably mounted îupon4 sapin î'32 secured to A¿bracket
The outer end of an arm 33 integral v/i't‘h seg
mental rgear 3i is pivotal-ly attached ’to fone end of '
a link 34. The other end of said link is pivotally '
attached to the upper end of an arm 35 rotatably
mounted upon a pin 36 secured to end wall 4, as
shown in Fig. l. Depending from pin 35 and se
cured to arm 35 is a hand operated lever 31. A
plate 38 is also secured to end wall 4 and is pro- ‘
vided with two or more radial slots 39 and 4D re
spectively. A hand operated det/ent 4I is slidably
mounted in suitable guides 42 provided on lever 31
and a spring 43 normally urges said detent 4I into
slot 39 provided in plate 38. A link 44 is pivotally
attached to detent 4I and lever 31 near the lower
ends thereof. It therefore is seen that by draw
ing the lower end of detent 4I toward lever 31
link 44 will be rocked downwardly, thus causing
detent 4I to move out of engagement with slot 39. 45
From the construction of the elements just de
scribed, it is seen that in order to tilt trough 24,
the operator simply grasps the lower end of lever
31 and detent 4I, whereby detent 4I will imme
diately be released from locking engagement with 50
plate 38, and then swings said lever in a counter
clockwise direction. This movement is imme
diately imparted to trough 24 through link 34, and
gears 3i and 30, causing said trough to swing
about its pivot. When the lever 31 has been
nating in a discharge opening, closure means nor
mally closing said opening, said closure means'
swung so that detent 4I registers with slot 40 in
Vplate 38, trough 24 will have been swung through
an angle of substantially 180 degrees, and any
foreign matter collected therein will be dis
charged. By releasing the grip on detent 4|
spring 43 will urge said detent into locking er1-v

For the purpose of illustration the'trough con

It is obvious, however, Y that they are
-equally applicable to. hoppers wherein a pair of
sliding gates are employed to close the discharge
