(01. 308-83)
It is the object of my invention to provide in a
railway-car journal-box means for preventing
the entrance of water into the journal-box waste.
In carrying out my invention I make the lower
5 portion of the front and side walls of the journal
box hollow, and I provide for communication be
tween the upper portion of - the cavity in the
hollow walls and the interior of the journal-box,
whereby any water which enters the upper por
.10 tion of the journal-box or which condenses upon
the side or front walls thereof will run down
such walls'and ‘enter the cavity in the lower por
tion thereof from which it is removed by a suit
able drain.
The accompanying drawing illustrates my in
vention: Fig. 1 is a vertical transverse section
through a railway-car journal-box on the line
i—! of Fig. 2; Fig. 2 is a vertical axial section on
the line 2-2 of Fig. 1; Fig. 3 is a fragmental view
similar to Fig. l but on an enlarged scale; Fig. 4
is a fragmental vertical section on the line 4--4
of Fig. 2; and Fig. 5 is a fragmental horizontal
section on the line 5—5 of Fig. 2.
In‘the journal-box I 0 shown in the drawing the
curved bottom of the box is made hollow tov pro
‘vide .a cavity ll which‘extends well up the sides
and front of the box substantially to the upper
secured in spaced relation to the inner face of
the lid [6. The lower edge of the shield I‘! is
disposed at the front of the box above the open
ing of the cavity ll, whereby any water drops
ping from the door l6 will run down the shield I1 5
and be discharged from the lower edge thereof
into‘ the cavity II.
To prevent the loss of any oil thrown by cen
trifugal force by the ?ange or collar 20 on the
end of the journal 2|, the bridge-portions l3 at
the sides of the box are preferably located in
the plane of the collar 20 and their upper sur
face is made trough-shaped to con?ne laterally
any downwardly flowing oil and direct it into the
journal-box waste. If desired, the side walls of 15
the journal-box, for‘ a short distance above the
bridges , l3, may be provided with spaced ribs
22 which serve to prevent oil from escaping lat
erally into the cavity II, where it would be lost.
I believe that, especially in cold weather, at 20
least some of the water collecting in the journal
box results from condensation of moisture upon
the inner surfaces of the journal-box walls. In
my construction the cavity ll serves to provide
heat-insulation for the metal which is in contact
with the waste; and,ras air can circulate freely
through the cavity, any condensation will occur
surface of the waste 12 therein and opens at its ‘ therein rather than in the waste compartment.
I claim as my invention:
top into the interior of the journal-box. Desir
ably, the opening which provides communication
between the cavity I! and the interior of the
journal-box is continuous, horizontally, along the
sides and front wall of the journal-box except for
the presence of bridge-portions I3. Additional
bridge-portions or struts M may extend across
the cavity H to stiffen the inner face of‘ the.
bottom of the box. The journal-box isprefer
. ably, although not necessarily an integral cast
ing, with the cavity formed by a core.
With the construction described, any water
1. In combination with a railway-car axle hav
ing journals and a collar adjacent each journal,
a journal-box receiving each journal and its as
sociated collar, said journal-box being formed
with hollow walls to provide a cavity which, at its
top, communicates with the interior of the jour
nal-box through an opening positioned to re- .
ceive water running down the inner surface of
the journal-box walls, said journal-box being
provided ‘with bridge-portions bridging said cav-‘
ity at the top thereof in the plane of said collar,
running down the side walls of the box, instead
of entering the waste l2, will enter the cavity II
said cavity also being provided with a drain.’
2. A railway car’ journal-box having an in
from which it may readily be drained. Prefer
ably, the cavity “ is drained by a generally U
shaped conduit l5 which opens exteriorly at the
clined lid closing an open end thereof, the lower
portion of said journal-box being formed with
hollow walls to provide a cavity, said cavity at it's
top communicating with the interior of the jour
inner end of the journal-box ‘and which pro
vides a trap adapted to seal the interior of the
journal-box from the admission of air.
Journal-boxes are customarily made with doors
50 or lids it which occupy an inclined position and
the upper portion of which lies above the journal
box waste. To prevent water collecting on the
inner surface of the lid from dropping into the
journal-box waste, I prefer to employ a shield I‘!
55 in the form of a sheet-metal member which is
nal-box through an opening extending across the
front of the journal-box adjacent said lid, a shield
mounted on said lid in spaced relation to the
inner surface of said lid in position to receive
water falling therefrom, the lower edge of said
shield being disposed over said opening whereby
water falling from the shield will pass through
said opening into said cavity, and a drain for
said cavity.

3. A railway car journal-box, the lower por
tion of said journal-box being formed with hol
low walls to provide a cavity, said cavity at its
top‘ communicating with the interior of the
journal-box through an opening including por
tions which extend longitudinally of said jour
nal-box along the sides thereof to receive water
running down the inner surface of the side walls
of the journal-box, and a drain for said cavity.
4. The invention set forth in claim 3 with the
addition that said journal-box is formed as an
integral casting.
5. The invention set forth in claim 3 with the
addition that said drain includes a. U-shaped por
tion forming a trap.
