page_text: I, HAMILTON ROGERS, of Toledo, County of Lucas, and State of Ohio, U.S.A.,
Engineer, do hereby declare the nature of this Invention, and in what manner the
same is to be performed to be particularly described and ascertained in and by
the following statement :-
The object of my Invention is to provide means by which the packing necessarily
employed shall be retained in its proper relation to the journal, also, to prevent dirt
from entering the box and mixing with the lubricant contained therein, also, in
providing a drip box into which any of the lubricant that may travel along the
journal may be led therein and saved; I have also provided a scraper intermediate
the rear end of the journal bearing and box, so pivoted as to allow a semi-revolution
to conform to the direction of revolution of the axle, thereby tending to prevent
escape of the lubricant in the direction of the axle, and returning the same to the oil
receptacle in the box.
I have also provided a peculiar and valuable form of metal packing, particularly
adapted to insure an unvarying capillary feed of lubricant to the journal, as will more
fully appear in the description, reference being made to the accompanying drawings:
in which :-
Figure 1 represents a longitudinal vertical sectional view of my improved
device.
Figure 2 is a cross sectional elevation of the same on the lines x. x. Figure 1.
Figure 3 is a detail view of my improved dust board.
A designates the car axle, B the bearing, C the wedge; these parts are of usua!
construction, and therefore need no further description.
D represents the upper, G the lower portion of a dust board adapted to encircle the
axle within the box and prevent the ingress of dust to the lubricant. The part D is
preferably formed of a width sufficient to allow the formation of grooves E into
which slide portion F, F, of the part G, slide F, F, being of sufficient length to extend
past the upper end of the part D and enter perforations J of a spring H loosely
retained in place upon the upper end of part D, and are held under the tension of
spring H by gibs or keys K, or in any preferred manner.
M is a scraper journaled in the part D of the dust board by means of rod L passing
through the same; the rod L extends upward from the part D a sufficient distance

page_text: to allow spring H, (which has a central perforation) to be held in place thereby, part D
is cut away sufficiently to allow the scraper to rest therein and to be held into
frictional engagement with the axle.
Qis a box supplemental to, and formed beneath the main box and is preferably
cast integral therewith, upon its under side is fastened a spring U¹ having a catch U,
for the purpose of holding a drip pan, or lubricant receptacle, T within its proper place
within box Q.
R is an inclined cut away portion of the main box adapted to lead any of the
lubricant that may escape upon the axle into the drip pan T, as the same may drop
onto the inclined projection S of the box Q.
P are longitudinal ribs or projections upon the bottom of the main box, these ribs
having communicating passages O through which the lubricant may flow to maintain
an even height in the box. These ribs are for the purpose of retaining the packing P₁
in place and preventing the same from moving in the direction of rotation of the
axle so far from the centre of the box as to lessen if not altogether stop the feed of
lubricant by capiliary attraction.
for
In the packing shown in figure 1, I have illustrated an improved means
insuring an even feed of the lubricant. I employ a metal packing P₁ formed of wire,
metal shavings, or a resilient metal of analogous character, which by its elasticity
tend at all times to hold the cotton waste or any fibrous material that may be incor-
porated therewith into engagement with the axle journal; or, if preferred, the metal
packing alone may be employed.
It will be seen that this feature is of great value when it is considered that the
cotton waste usually employed when saturated with lubricant is of such density and
weight as to fall below the point of frictional engagement, or in the absence of
ribs P, be rolled into one corner of the box in a position to be practically
useless.
In operation, the axle journal is placed into position within the box, the dust board
is adjusted around the axle by inserting the parts F of the bottom portion G through
the perforation J of spring H, and are held in place by gibs or keys K, by which the
dust board at all times is caused to encircle the axle, and be held into frictional
engagement sufficiently to prevent the ingress of dust, at the same time by the
attachment of these parts through the medium of spring H they are allowed to
yield to the motion of the axle.
When the dust board is in position as described, the scraper M is brought to bear
upon the axle between the dust board and bearing B, the outer end of the scraper
radiating towards the inner portion of the box at all times without reference to the
direction of rotation of the axle as the friction upon scraper M revolves the same to
correspond to the direction of the axle rotation, the inclined portion of the cut away
part of the dust board allowing the scraper to rest in an inclined relation to the length
of the axle, thereby tending to lead the lubricant that may tend to travel upon the
axle back to the main box.
The packing composed of resilient metal or metal wound with cotton waste
is held from lateral displacement by ribs P, and any of the lubricant that
may have passed the scraper and dust board is led down the side of the main box,
thereby not only effecting a great saving of lubricant, but preventing the flow
of the same on the wheels of the train, and other parts of the running gear of
the car:
My improvement can be attached to the present form of car axle boxes with but
slight expense.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what
1 claim is;
1st. In a Car Axle Box, in combination with a car axle, a dust board composed
of two sections yieldingly connected, as and for the purpose set forth.
2nd. In a Car Axle Box, a pivoted scraper adapted to automatically adjust the

page_text: inclination of the same toward the box, and in the direction of the rotation of
the axle, as and for the purpose set forth.
3rd. A Car Axle Box, provided with ribs having communicating passages, in
combination with a flexible packing, as and for the purpose set forth.
4th. A flexible packing for Car Axle Boxes, composed of whole or in part, of
resilient metal and means for holding the same, in frictional engagement with the
axle journal, as and for the purpose set forth.
5th. A Car Axle Box, provided with a supplemental removable drip pan, and
means for leading the scraping lubricant therein, as and for the purpose set
forth.
6th. In a Car Axle Box, a dust board having a scraper pivoted therein, adapted
to rest upon the axle, as and for the purpose set forth.
