IMPROVEMENTS IN "CAR AXLE BOXES
Year: 1885

page_text: We RUSSELL BREWER and CHARLES MARCY ZEH, both residing at Newark,
in the county of Essex and State of New Jersey in the United States of America,
gentlemen, do hereby declare the nature of the invention for IMPROVEMENTS IN
"CAR AXLE BOXES" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:―
This invention has relation to car axle boxes and it consists in the construction
and novel arrangement of devices, all as hereinafter set forth, and pointed out in
the appended claims.
In the accompanying drawings, the letter A, designates the encasement or
external box upon which rests the equalizer box. This box is provided on the
underside of its top portion in front and rear with transversely concave bearings B,
which are engaged by the transversely convex lugs or rockers C, of the interior
bearing frame D, the lateral branches E, E, of which are provided with elongated
bearings F, for the journals, a, a, of the main antifriction roller G, which bears on
the axle journal H. The bearings F, are a little elongated horizontally to allow a
slight forward or backward motion to the bearing roller G, sufficient to prevent
said roller to come in contact with the lubricating rolls, which are arranged in
bearings of the frame D, in front and rear and below the level of the main bearing
roller. Usually two sets of lubricating rolls are employed, the lower K, K, dipping
into the lubricating substance in the receptacle or oil chamber L, in the bottom of
the box A, and the upper set N, N, engaging the lower set.
The upper rolls N, N, which are engaged by the journal in front or rear
according to its direction of movement are strengthened in position by the guides P,
of the box A, which are located respectively in front and rear of the fratne D, in
engagement with those portions of said frame where the bearings of said rolls N, N,
are located.
R, is a wheel or disc which is pivoted to a bearing A, having a slight rolling
movement, and adapted to come in contact at times with the end of the axle
journal H. It is designed to take up the end thrust of the journal. The weight
of the car is supported through the concaved bearings B, of the box by the bearing
frame D, and its roller upon the axle journal.

page_text: When the car is moved forward in either direction, the revolution of the axle
journal causes the main roller G to pass by means of the shifting bearings F, over
the crown of said journal from front to rear a slight, distance, and bringing into
action the lubricating rolls in front.
The lateral thrust and the vibratory movements of the axle whereby it deviates
from parallelism are accommodated in this box, by means of the convex lugs or
rockers C, of the bearing frame D, and by the concave bearings of the main box,
which are engaged thereby, so that sufficient lateral vibratory movement is allowed
to the bearing frame D, this being automatically constructed by the axle journal
through the bearing rollers.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is
1. In a car axle box, the combination with the antifriction roller bearing upon
the axle journal of an inner bearing frame supported in place by the axle journal
and having elongated bearings for the journals of said roller, substantially as
specified.
2. In a car axle box the combination with the axle journall, of a shifting anti-
friction roller bearing upon said axle journal, substantially as specified.
3. In a car axle box, carrying the antifriction rollers the inner bearing frame
and having transversely convex lugs or rockers, engaging concaved bearings of the
box, whereby the bearings are automatically governed by the vibratory movements
of the axle journal, substantially as specified.
4. The combination with an external box of the internal roller frame engaging
concave bearings of the box, and having a shifting bearing roller, to engage the axle
journal which automatically governs the roller frame, substantially as specified.
Dated this 6th day of October 1885.
