COALING GATE‘ FOR LOCOMOTIVES

13 Claims.
My invention relates to improvements in coal
chutes.
It has for one object to provide a new
and improved form of coal chute particularly
forv use in connection with locomotive fueling
stations wherein the gate which controls the ?ow
of coal will not jam, will not permit unauthorized
or unintended leakage of coal, will insure a uni
form ?ow of coal from the bin while preventing
skimming or control of the character of coal by
Other objects will appear
from time to time throughout the speci?cation

Like parts are indicated by like characters
throughout the speci?cation and drawings.
I is a coal bin having an inclined bottom wall
2', a vertical front wall 3, there being an aperture
or port 4 in the front wall immediately adjacent
the lower extremity of the inclined bin. This
aperture4 is encircled by an angle ?ange 5 to
which is bolted a ?xed gate chute 6 which is
rectangular in cross section, the lower ?oor ‘of
which is in general alignment with the floor 2.
1, ‘l are brackets on the upper wall of the ?xed
chute. 8 is a rock shaft rotatable in those
brackets. 9, 9 are‘sleeves bolted to the opposed
ends of the rock shafts having lugs ID to which
arebolted control levers H from which depend
downwardly operating rods l2, from which the
' engineer or ?reman in the tender may open or
close the gate. Extending downwardly along op
~ posed sides of the ?xed chute from and rigidly
-mounted on the rockshaft 8 are rock arms I3;
A lower gate link I4 is pivoted to each rock arm‘
13 and an upper gate link 15 slotted at I6 is en
gaged by the pivot pin ll that joins the three
links. The gate is a two part gate, the upper
part comprising an arcuate member l8 having
Cl Cit inwardly turned ?anges at each end pivoted at
(Cl. 193-21)
IS on the side walls of the ?xed chute. The link
[5 is pivoted to a lug 20 on each of said inturned
ends so that the link I5 causes rotary movement
of the upper gate portion l8 about its pivot point.
The upper gate arcuate portion l8 has a straight
cutting edge extending clear across the chute.
The lower gate member comprises two superposed
arcuate gate sections 2|, 22, section 2| being
reinforced by 22 and both being supported on a
stirrup 23 having stirrup arms also pivoted at
[9. The link 14 pivoted to a lug 24 causes oper
ation of this stirrup member. Reference to Fig
ure 6 shows that the undercut portion does not
have a straight cutting lip but tapers upwardly
to a point at the center.
Figure 3 shows the parts in the closed position.
Figure 4 shows the parts in the open position.
A counter clockwise rotation of the rock shaft 8
?rst takes place without movement of the gate
l8 because the pin ll slides in the slot l6 and -' ’
cushions the opening movement of the lower
gate section. Later on as the excursion proceeds
to the position shown in Figure 4 both gates are
opened. On the return or closing movement
clockwise direction of the rock shaft 8 immedi
ately causes a forward or closing movement of
the lower gate but the closing movement of the
upper gate does not start until the pin IT has re
turned from the position of Figure 4 in the right
hand end of the slot to the position of Figure 3 30
in the left hand end of the slot.
The result of this is that in order to open the
gate, the operator must manipulate the rock shaft
to ?rst start the withdrawal of the lower pointed
gate member and then to ?nish with the com
pletion of its withdrawal and the opening of the
upper straight edged gate portion. This results
in a full ?ow of coal. As the gate closes, the
upper gate portion remains at rest until the
pointed gate portion has come partially into play 4.0
tending to divide the flow of coal and tending as
the two gates come together to gradually restrict
the passage up to a point where the pointed gate
is immediately adjacent the upper gate when
coal flows through two passages, one at either
side of the chute. Therefore coal movement is
entirely stopped. This arrangement insures that
a uniform ?ow of coal will take place.
Depending downwardly from the pivot pins i9
on the fixed chute is a yoke 25 which yoke ex 50
tends across beneath the ?xed chute. 26 is an
adjustable chute pivoted on the yoke. This ad
justable chute extends upwardly behind and
above the lower extremity of the fixed chute and
has at its end a boot 2‘! adapted to catch and 55
2,107,781

guide the coal. 28 is a ring associated with the
boot which may be grasped by a hook 29 in the
hands of the operator to pull the adjustable
chute down from the position shown in dottedlines
in Figure l to the position shown in full lines.
30 is a bail to which is fastened a holding rope
3! which extends up to any suitable counter
balance. Figure 2 shows the angle of move
ment possible for this adjustable chute where
10 by the coal may be properly positioned on the
tender of the locomotive.
depending therefrom, links each separately pivot
ed on the upper and lower gate and pivoted on
the rock lever, one of said links having a slot
whereby movement of the rock lever and the
other link takes place through a limited excur
sion without movement of the slotted link.
