5 Claims.
(Cl. 214-54),v
My invention relates to the construction of
mine cars and more especially to that type of
mine car which is equipped with a swinging end
gate that is automatically latched when closed
1'5 and which is adapted to be automatically tripped
to open for the purpose of releasing the car load
ing as it arrives at the unloading bins or chutes.
,This application is a division of my co-pending
application ?led January 6, 1932, Serial No.
‘710 585,015.
'
An object of my invention is to providemeans
in combination with an end-gate latching mech
anism which ?rst automatically engages the latch
operating means provided at the unloading bins
515 or chutes for the purpose of unlatching the end.
gate, and thereafter automatically disengages
the latch operating means as the car assumes its
unloading
position.

Other objects of my invention relate to certain
:20 novel features of construction, combination, and
arrangement of parts which willbe hereinafter
more fully described and particularly pointed out
in the appended claims, reference being had to
the accompanying two sheets of drawings in
/25 which:

Fig. 1 is a side elevation of a mine car embody
ing my improvements;

~
Fig. 2 is a front elevation of the same car;
Fig. 3 is a part horizontal section taken along
"30 the line 3-—3 of Fig. 2; and '
Fig. 4 is a part vertical section taken along the
line 4-4 of Fig. 2.
~
In the drawings the numeral l0 indicates the
mine car in which is embodied my improvements,
535 and in Fig. 1 the mine car I 9 is ‘shown in posi
tion at the automatic unloading point of the
tipple. The automatic unloading means is not
a part of my invention and any arrangement
would be suitable which would comprise a car
40 tilting device such as the tilting platform I I, and
a latch operating mechanism such as the biased
lever device I 2, shown diagrammatically in Fig. 1.
The car It comprises the car sides I3 attached
to which on the inside of the front upper cor
45 ners are the shaft support brackets M. The
brackets l4 extend above the top edge of the
sides I3 and are adapted to receive the shoul
dered and threaded ends l5 of the shaft IS. The
shaft I6 is secured in the brackets M by the cot
50 tered nuts l1, and by reason of the shouldered
engagement, the shaft It acts to maintain the
upper front corners of the sides l3 in rigid spaced
relation.
The front end of the car I 0 is closed by a
55 swinging end or door l8. The door l8 comprises
a steel plate l9 having its upper edge bent‘ or
rolled over to the outside to form a tubular top
edge 23 with the edge 2| bent ?at against the
outside of the door plate I9 and riveted thereto,
‘while its lower edge is similarly bent but in an '5
opposed direction. Riveted on the inside face
of the plate is at the top are the hinges 22 which
in turn are pivotally mounted upon the shaft l6.
Collars 23 functionally integral with the shaft [6
engage opposed faces of the outer pair of hinges 110
22, thus positioning the door IS in relation to
the sides of .themine car Ill. For stiffening pur
poses angle bars 24 at the ends and a pressed
steel recessed plate or stake 25 at the vertical
center are riveted to the inside face of the plate 515
I9. For latching the door It, the keeper plates
26 are riveted to the outside. of the mine car sides
~I3 at the lower front corners. On the front face
of the plate H! at the lower corners are riveted
the latch guides 21which guide the outer ends 20
of the substantially horizontal latches 28 while
their inner ends are pivotally attached to a ver
tical latch slide bar 29 by suitable means 30.
The latch slide bar 29 is slidably mounted in the
guides 3| and 32 riveted to the outside face of 525
the plate I9 on the vertical center. The upper
end 33 of the latch slide bar 29 is bent outward
for a purpose to be hereinafter described. Also
riveted on the outside face of the plate I 9 on
either side of the-vertical center and just above 1'30
the guide 3| are the cam brackets 34 having the
upward and outward sloping edges 35, the pur
poses of which will hereinafter be described.
Having thus described the structure of my mine
car I. will now describe its operation upon its 35
assumed arrival at the tipple loaded and ready to
be unloaded.
The car ‘ID as loaded is run onto a
car tilting device I l at the unloading point which
may, in the tilting platform type shown diagram
matically in Fig. 1, include stops 36 for the car 40
wheels 31. As the car wheels 31 engage the stops
36 the arrested momentum of the loaded car tends
to tilt the car I0 and the platform 38 forward
about the pivot point 39 until they come to rest at
a suitable unloading angle by engaging a stop not 45
shown. At the instant the car wheels 3‘! engage
the stops 36 the upper end 33 of the latch slide
bar 29 comes into engagement on its under side
with the suitably adapted end 40 of the biased
lever device I 2 (shown diagrammatically) pivot- 50
ally mounted to the structure 4| of the tipple.
The action of the biased lever device I2 in engage
ment with the latch slide bar 29 is such that as the
car I 0 tilts forward about the platform tilting
point 39 the latch slide bar 29 is raised, relatively 55

to its initial position on the front door l8, which
action results in withdrawal of the latches 28
from engagement with the keeper plates 26. As
the latches 28 disengage, the weight of the coal
against the swinging door l8 causes the latter to
swing outward and thus give ready exit to the
unloading position, and said end-gate so pivotally
unloading coal. As the car l0 continues to tilt
downward in its unloading operation after the
latches 28 are disengaged and the door 18 has
10 swung open, it is desirable that the biased lever
device 12 having done its work to be disengaged.
This is brought about by the outward sloping
edges 35 of the cam brackets 34 engaging the end
40 of the biased lever l2 and gradually disengag
15 ing the latter from the latch slide bar end 33.
When the point of disengagement is reached as
shown in dotted lines in Fig. l the latch slide bar
29 drops due to the action of gravity to its initial
position shown in Fig. 2. This also returns the
20 latches 28 to their initial position. When the car
is unloaded and is returned to a horizontal posi
tion, the door I8 tends, due to the action of grav
ity, to return to its closed position, and this return
movement brings the outer ends of the latches 28
25 into engagement with the sloping edges 42 of the
keeper plates 26. Since the latches 28 are pivot
ally attached to the latch slide bar 29 at 30 they
are free to rise along the slopes 42 in the guides
21 until the door I8 becomes closed, when the
30 latches 28 then drop into latched engagement
with the keeper plates 26 as shown in Fig. l. The
car I0 is then again ready to be loaded.
Although I have described and illustrated my
invention in considerable detail, I do not wish to
35 be limited to the exact and speci?c details there
of, as shown and described, but may use such
modi?cations in, substitutions for, or equivalents
thereof, as are embraced within the scope of my
invention or as pointed out in the claims.
