APPARATUS FOR TRANSPORTING MOL'I‘EN
MATERIALS
Spottiswoode W. Randolph, Baltimore, Md., as
signor, by mesne assignments, to Koppers
Company, a corporation of Delaware
Application July 1, 1936, Serial No. 88,476
5 Claims. (01. 105_2v0)
This invention relates to apparatus for the on a' railway truck E5. The vtrunnion l2 and’
transportation of molten materials, and more bearing l3 are formed with spherical bearing sur

tion metal (Fig. 3). It will be understood that

bearings adapted to receive trunnions mounted 10V
1G: One type of vehicle so employed comprises a con
tainer for the molten metal supported by means on the railway trucks.
For the purpose of tilting the container ID to
of trunnions, at either end, in bearings mounted
on railway trucks. In such vehicles the con
tainers are tiltable for the purpose of discharging
ll: their contents, tilting being e?ected by external
means, such as a crane operated hook, or by
means carried on the vehicle, such as an electric
motor mounted on one of the trucks and con
nected, through suitable gearing, to the con
tainer.
20
The present invention relates to vehicles of the
latter type, and has for an object the provision of
a suitable driving connection between the electric
motor or other source of power and the con
tainer, such means being employed that the con
2GI tainer may be tilted even though it be out of
alignment with the power shaft, due to inequali
ties in the track, sagging of thecontainer, per
manent misalignment of the parts, or for any
301 other reason. A further object is the provision of
a driving connection for the described purpose,
which will not be injured by misalignment of the
shaft and the container, occurring by reason of
the vehicle passing around curves or over ine
qualities in the track, or through other causes.
These and other objects, features and advantages will appear from the description which fol
lows, together with the accompanying drawing,
discharge its contents a suitable source of power,
such as a reversible electric motor I1, is provided.
The motor I‘! is connected by suitable reduction
gearing, indicated in Fig. 1, to a shaft l8, through
Which rotary motion is transmitted to the con- ‘
tainer ill by means now to be described. The
shaft i8 is journalled in bearings 21 and 23, car
ried by the gear casing 29, and is permitted sub- 8
stantially no end play.
As Will be best seen in Figs. 3 and 4, the trun
nion I2 is provided with a recess l9, rectangular
in cross-section, the upper and lower surfaces of
which are provided with liners Z0 andv 2| of anti
friction metal.* A hollow block 22,- rectangular in
cross-section,‘ is mounted'within'the recess I9,
?tting snugly between the anti-friction liners 20
and Eli. It will be perceived that the transverse
dimension of the block 22 is considerably less
than that of the recess l9, thus permitting the
block '22 a certain amount of horizontal planar
movement, both linear and angular, within the
recess l9. It will be understood that the term
“planar movement” refers to linear or angular 35
movement in which each element of the moving
member moves in a single plane, all of such planes
being parallel.

Fig. 1 is a side elevation of one end of a vehicle
of the type to which the present invention is
adapted;

entirely through, the central aperture in the
block 22, ?tting snugly between the vertical walls
Fig. 2 is an end view of the vehicle of Fig. 1;
Fig. 3 is an enlarged longitudinal vertical sec
23 and 24 thereof. The shaft l8 and block 22 are
secured together by means of pins 25, 25’ which
45 tion through the container supporting bearing
are threaded into the walls 23 and 24 of the block
and driving connection, on line 3—3 of Fig. 4;
Fig. 4 is a vertical transverse section on line
4-4 of Fig. 3; and
_
Fig. 5 is a horizontal section‘ on line 5—5 of
50 Fig. 3.
Referring to Fig. 1, a container It, provided
with a suitable charging and discharging opening
II, is provided at one end with a trunnion I2
which is supported in a bearing I3, the latter
65 being carried by a suitable pedestal l4 mounted
22, and extend inwardly into engagement with
vertically elongated slots 26, 26' formed in the
vertical surfaces of the shaft 18. The latter hav
ing a vertical dimension somewhat less than that
of the central aperture of the block 22, is per 50
mitted a certain amount of vertical planar move-7
ment, both linear and angular, within the block.
A lubricant chamber 35! is provided between the’
gear casing 29 and the bearing l3, and communi
cates with the recess H3. The chamber 30 is 55

of wheeled trucks, bearings carried by said trucks,
of lubricant, and to act as a reservoir supplying
lubricant to the bearings l3 and 28, and’ to the

.
Since the block 22 is secured to the shaft l8,
which latter is supported without substantial end
play, there will be no substantial longitudinal
movement of the block 22 and shaft ,l8 with
respect to the trunnion l2. However, since the
10 block 22 is permitted a limited transverse move
ment within the recess l9, and the shaft l8 may
have a limited vertical movement within the
block 22, it is apparent that the driving connec
tion thus formed between the shaft I8 and the
15 trunnion 12, will be‘operative despite such mis
alignment of the shaft and container as is likely
to occur in service, and will not be injured by
such misalignment.
.
Due to the inherently rugged nature of the
20 elements making up the drivingconnection of
the present invention, it is particularly well adapt
ed to transmit the considerable torque necessary
for tilting the heavy container ?lled with molten
metal, and to withstand injury.
25
The terms and expressions employed in the,
foregoing speci?cation are‘ terms of description
and not of limitation, and it is recognized that
many variations of the described mechanism may
be made without departing from the scope of the
present invention. For example, the recess l9,
~ block 22 and shaft 18 need not-be rectangular,
so long as the outer'surfaces of the block 22 are
complementary to the inner surfaces of recess I9
and the inner surfaces of block 22 are comple
35 mentary to the adjacent surfaces of theshaft
l8, and so long as each member has two opposite
