"IMPROVEMENTS IN RAILWAY CARRIAGE AXLE BOXES AND JOURNAL BEARINGS."
[A communication from abroad by Charles Erwin Candee, of the City County and
State of New York, and Albert Gallatin Story, of Little Falls in the County of
Herkimer, State of New York United States of America]
These improvements relate to car axle boxes containing anti-friction rollers for
the journals of the axles.
The Invention consists, 1st, in an improved construction of box, 2nd in devices
for ensuring continuous lubrication, and 3rd in an arrangement of packing devices
that render the box tight to exclude dust and prevent escape of oil.
The bottom portion of the axle box is formed as a basin to contain the lubricant,
and the box is closed on all sides, at the front and the back by plates, all the joints
being packed to exclude dust. The box is divided by a vertical partition to form
the two chambers of different size, the larger one to contain the anti-friction
rollers and journal of the axle, and the smaller chamber to contain the lubricating
devices. The latter chamber is accessible by removal of its covering plate, and
the two chambers connect by an opening in the partition, so that the lubricating
material shall be at the same level in both, and pass freely from one to another.
The axlo extends through a stuffing box in the back covering plate of the axle box
and through the larger chamber and partition. Three anti-friction rollers are

page_text: employed of which one, which is larger than the two others, is placed directly
above the axle journal, the smaller rollers being arranged at opposite sides of the
journal with their axes slightly above the centre of the axle so that the axle is
centered between the rollers. The rollers are mounted loose upon spindles which
have bearings in the front of the axle box and abut against the front covering
plate, and the rear plate is formed with recesses that receive the rear ends of the
spindles. In the back plate are set screws taking against the ends of the
spindles for use in setting them up tightly. The opening in the stuffing box for
the axle is eccentric so that the axle bears on the box only at the lower side of
the opening. The opening in partition is also eccentric to prevent the contact of
the shoulder on the axle with the partition except on the lower side. The box
contains suitable packing that is surrounded by a lapped circular band of flexible
or spring metal, and the gland of the box is provided with set screws taking upon
the band so that the band can be compressed and the packing made as tight us
necessary. With these packing devices the box can be made dust and oil tight.
The lubricating devices are as follows:-The hub of the upper friction roller is
formed to project over the oil chamber and the projecting portion is made as a
toothed wheel. In the oil chamber is a flanged disc or wheel sustained on a stud
that projects from the front plate, and around the wheels is passed a chain provided
with buckets or knobs. The chain being moved by the revolution of friction
roller, the buckets carry the oil up from the oil chamber to the roller.
ensures a continuous supply of lubricant to the bearings of the roller.
This
This construction provides for the convenient access to and removal of the anti-
friction rollers and other parts contained in the box. The rollers steady the
journal and prevent any lateral or oscillating movement. The box being air tight,
dust cannot enter nor oil escape.

openings in the box and gland and prevent the packing from entering.

IMPROVEMENTS IN RAILWAY CARRIAGE AXLE-BOXES AND JOURNAL-BEARINGS
"
A cominunication from abroad by Charles Erwin Candee, of the City, County, and
State of New York, and Albert Gallatin Story, of Little Falls, in the County of
Herkimer, State of New York United States of America
These improvements relate to car-axle boxes containing anti-friction rollers for
the journals of the axle.
The Invention consists first in an improved construction of box, second in
devices for ensuring continuous lubrication, and third in an arrangement of packing
devices that render the box tight to exclude dust and prevent escape of oil.
The axle box is formed with a cavity in its lower portion for containing the
lubricant and is divided by a vertical partition into two compartments, one for the
lubricating devices and the other for the anti-friction rollers, and the back plate
has a packing box at the outside containing adjustable packings
In the accompanying Drawing Figure 1, is a front view of an axle box containing
the improvements with the front plate removed. Figure 2, is a vertical transverse
section of the box. Figure 3, is a horizontal section on line x x of Figure 1.
Figure 4, is a vertical longitudinal section on line y y of Figure 3, and Figure 5,
is a cross section of the packing gland.
A is the axle box having its bottom portion a formed as a basin to contain the
lubricant. The box is closed on all sides, at the front by a plate b, and at the back
by a plate c, all the joints being packed to exclude dust. The box is divided by a
vertical partition d, to form two chambers B B¹ the former and larger one B, to
contain the anti-friction rollers and journal of the axle, and the smaller chamber B¹
to contain the lubricating devices. The chamber B¹ is accessible by removing the
front plate b, and the two chambers connect by an opening d¹, in the partition, so
that the lubricating material shall be at the same level in both and pass freely
from one to the other.
C is the axle extending through a stuffing box D, in the back plate c, and
through the chamber B and partition d. cfg are the friction rollers, placed, the
larger one e, directly above the axle journal, and the two smaller rollers f. g. at
opposite sides of the journal, with their axes slightly above the centre of the axle,
so that the axle is centered between the rollers. The rollers are mounted loose
upon spindles e¹ f1 and g¹ respectively, which have bearings in the front of box A,
and abut against the covering plate b, the rear ends of said spindles being received
in recesses h formed in the rear plate c; t are set screws on the rear plate taking
against the ends of the spindles for use in setting them up rightly.
The opening in the stuffing box D, for the axle, is eccentric so that the axle
bears on the box only at the lower side of the opening as seen clearly in Figures 2
and 4. The opening in partition d, is also eccentric to prevent the contact of the
shoulder i on the axle with the partition, except on the lower side. The box D,
contains suitable packing that is surrounded by a lapped circular band k, of
flexible or spring metal as clearly shown in Figure 5, and the gland l, of the box
is provided with set screws n to act upon the band k, so that the band can be
compressed and the packing made as tight as necessary.
With these packing
devices the box can be made dust and oil tight.
The lubricating devices are as follows:-The hub of the upper friction roller e, is

page_text: formed to project over the oil chamber B¹, and the projecting portion is made as a
toothed wheel m. In the oil chamber is a flanged disk or wheel o, sustained on a
stud p, that projects from the front plate b and around the wheels m o is passed a
chain Figure 1 provided with buckets or knobs ». The chain being moved by
the revolution of friction roller e, the buckets carry the oil up from the oil
chamber B' to the roller, whereby a continuous supply of lubricant to the bearings
of the roller is ensured.
The construction of axle box shown provides for the convenient access to and
removal of the anti-friction rollers and other parts contained. The rollers steady
the journal and prevent any lateral or oscillating movement. The box being air
tight, dust cannot enter nor oil escape.
It is preferred to place at each side of the packing, bevelled washers u, shown in
Figure 2, which cover the openings in the box and gland and prevent the packing
from entering.
Having described the nature of the said Invention and the manner of performing
the same 1 declare that what I claim as the Invention to be protected by the
herein before in part recited Letters Patent is —
1st The car axle box A, divided into chambers B B¹, the smaller chamber
containing lubricating devices and the larger chamber containing anti-friction
rollers e, f, g, for the axle journal, substantially as shown and described.
2nd The car axle box A, closed on all sides and containing anti-friction rollers
for the axle-journal, and provided with packing box D, for the axle where it enters
the box, substantially as described
3rd The axle box A, provided with partition d, and back plates c, having
openings in which the axle is sustained eccentrically by anti-friction rollers, and
the packing box D, fitted with spring band and set scrows n, all substantially as
shown and described.
4th The combination of anti-friction roller e provided with toothed wheel m,
the loose wheel o, in the oil chamber, and chain or band q connecting the wheel,
substantially as shown and described.
5th The spring band and screws n in combination with packing box D and
axle C, substantially as shown and described
6th The anti-friction roller e provided at one end with a projecting gear
wheel m for receiving and giving motion to a lubricating chain or band
substantially as described.
In witness whereof I the said William Clark have hereunto set my hand and
seal this Twenty-third day of June AD 1882.
