JEFFERSON DAVIS JONES, OF TEMPLE, TEXAS.
To all whom it may concern:
Be it known that I, JEFFERSON DAVIS
JoNEs, a citizen of the United States, resid-
ing at Temple, in the county of Bell and
5 State of Texas, have invented new and use-
ful Improvements in Journal- Boxes, of
which the following is a specification.
This invention relates to improvements in
journal boxes for the axles of railway cars
10 and the like and particularly to a novel con-
struction of roller-bearing and lubricating
means therefor, the object of the invention
being to provide a construction of journal
box in which a series of bearing rollers may
15 be mounted in a novel manner to allow the
journal to turn freely and to effectually
withstand the strain falling thereon, and to
provide a simple type of lubricating means
for effectually lubricating the meeting sur-
20 faces of the journal and bearing.
The preferred embodiment of the inven-
tion is illustrated in the accompanying draw-
ing, in which:-
Figure 1 is a front elevation of a journal
25 box embodying my invention. Fig. 2 is a
vertical transverse section thereof. Fig. 3
is a vertical front to rear section thereof
taken centrally through the box.
Referring to the drawing, 1 designates a.
30 portion of the truck of a car, 2 a hanger
bracket carried thereby, 3 a car axle, 4 a
wheel mounted thereon, and 5 the journal of
the axle. The journal box is mounted for
vertical movement in the usual manner in
35 the bracket 2, and comprises upper and
lower sections 6 and 7, the meeting faces
of which are formed to provide an annular
chamber 8 receiving the journal 5. The sec-
tions 6 and 7 are detachably connected by
40 vertical bolts 9 and are slidably engaged
with the bracket in any preferred manner.
The inner or rear side of the chamber 8 is
closed by a rear cover 10 having an opening
11 therein of sufficient size to receive the
45 outer unreduced end of the axle 3, while
the forward end of the chamber is closed by
a cover plate 12, said plates being secured
in position by bolts 13 passing therethrough
and through the box sections 6 and 7. The
50 journal 5 is of reduced size with respect to
the body of the axle 3 and is provided at its
outer end with a collar or head 13' coexten-
sive in diameter with the axle, thus forming
with the coperating parts of the box an
55 annular runway around the journal to re-
ceive a series of bearing rollers 14. These

rollers hold the journal properly spaced
from the wall of the box and permit it to
turn with a minimum degree of friction.
The cover plate 12 is provided with an open- 6o
ing to receive the journal-head 13' and is
provided on its outer side in line with said
opening with an integral offset 14' forming
an oil or lubricant chamber 15, said enlarge-
ment having an upwardly extending neck 65
cored to provide a passage 16 through which
the oil or lubricant may be introduced into
said chamber. The upper end of the neck
terminates in an externally threaded nipple
17 engaged by a threaded closing cap 18. 70
The head 13' is slightly smaller in diameter
than the opening in the plate 12 to form an
intervening narrow feed duct 19 which com-
municates with the oil chamber 15. The
head 13' regulates the size of this duct, so 75
that but a restricted amount of oil can pass
therethrough into the chamber 8. The inner
side of the duct is also partially closed by
the outer ends of the rollers 14, so that the
amount of oil passing to the rollers cannot so
at any time be greater than that which wuld
be taken up by the rollers and transmitted
by the motion of the parts to the contacting
surfaces, thus retaining a body of oil in the
chamber 15 and preventing the journal box 85
from being flooded therewith.
It will be seen that the construction of the
box is such as to permit of ready assemblage
and disassemblage of its parts and that the
joints are close enough to restrict the en- 90
trance of dust and dirt to the interior, while
the arrangement of the parts of the journal
and the roller bearings serve to secure a co-
action between them to regulate the feed of
the oil thereto from the oil chamber. Hence 95
waste of oil will be effectually prevented.
Having thus described the invention, what
is claimed as new, is:-
In a journal bearing for axles, the combi-
nation of a journal box comprising a hori- 100
zontally divided body embodying upper and
lower sections forming a bearing chamber,
vertical tie-bolts connecting said sections on
opposite sides of said chamber, a cover plate
closing the outer side of the bearing chamber 105
and formed with an opening and an integral
central vertical exterior enlargement provid-
ing an oil chamber communicating through
said opening with the bearing chamber, said
enlargement being formed in its upper end 110
with a filling passage communicating at its
lower end with the oil chamber and project-
