Improvements in Axle-boxes for Railway Vehicles.
We, PATRICK BROWNLEY, of St. John, in the County of St. John, Province of
New Brunswick, Dominion of Canada, Brass Finisher, and JAMES STRATON of said
St. John, Barrister at Law, 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:-
Our invention relates to that class of journal boxes in which the journals are auto-
matically lubricated; and it consists in certain novel features hereinafter fully set
forth and claimed, the object being to produce a simpler, cheaper and more effective
device of this character than is now in ordinary use.
The nature and operation of the improvement will be readily understood by all
conversant with such matters from the following explanation.
In the accompanying drawing :-
Figure 1 is a vertical longitudinal section of a car journal-box provided with our
improvement; and
Figure 2 a vertical transverse section of the same taken on line x, x of Figure 1.
Like letters and figures of reference indicate corresponding parts in the different
figures of the drawings.
A represents the body of the journal box which is supported on the car in the usual
manner, and B, the axle.
The axle is reduced at its outer end forming the journal C between a shoulder b, and
annular flange d.
The body A is preferably rectangular in cross-section and to a bed-piece f in the
top thereof is secured a bushing g which bears upon the journal C.
A longitudinally arranged partition h is secured within the box below the journal,
forming a chamber D for receiving waste or packing.
The space between the partition h and the bottom of the box forms an oil
reservoir G hereafter described, the bottom i being inclined outwardly as shown in
Figure 1.
A circular or nearly circular box H is secured to the outer end of the body A, by
bolts passing through lugs m on said body, the journal flange d projecting through
an opening in the inner box wall.
The box is provided with a door p, in its outer face and may be cast integral with
the body A, if preferred, instead of being bolted thereto.
An arm t, is secured centrally to the end of the journal C, and is revolved thereby
in the chamber v, of the box H, said arm being provided with a forked head w
(Figure 2) the prongs of which may curve or slope laterally after the manner of
propeller-wings.
An opening 15, connects the packing chamber D with the box chamber v, through
which the packing may be passed, said opening being closed by a door 16, at its
outer end.
A longitudinally arranged inwardly inclined distributing shelf 17 is secured within
the body A at each side of the journal C, an inwardly inclined duct 18 leading from
the chamber of the box H, onto each shelf 17.
In the use of our improvement the reservoir G is supplied with oil or other
lubricant, a portion of which is discharged therefrom into the box H.
As the axle revolves the agitating art rotates in the chamber v of said box. The
forked head w of said arm carries the lubricant with it from the reservoir and .a
portion thereof clinging to the walls of the chamber runs back into the ducts or
gutters 18.
Thence it runs onto the shelves 17, and as said shelves are inclined rearwardly as
well as inwardly the lubricant is thereby distributed continuously onto the journal and
packing in the chamber D.

page_text: Should the oil overflow the chamber D it will pass downward through conductor 19
at the rear of said box into the reservoir, or over the front of said packing chamber
into the chamber v:
It will be seen that the arm t constantly raises the lubricant and supplies it directly
to the hearings thus obviating the liability of these parts becoming overheated.
We do not confine ourselves to employing packing in the chamber D as the
device can be used without it in many cases and still keep the journal sufficiently
lubricated.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we wish it understood that
we claim
First. In a journal box of the character described, the combination of a body
provided with a bushing in its upper portion a horizontal partition below the axle
opening forming a packing chamber and lubricant reservoir; inwardly inclined dis-
tributing shelves above said packing chamber; a box on the outer end of said body
into which the reservoir opens; ducts leading from said box onto said shelves; and
an arm secured to the journal and fitted to rotate in said box substantially as and for
the purpose set forth.
Second. In a device of the character described, the combination of a body; a
bushing bearing upon the axle journal; a box in the outer end of said body provided
with a door; a packing chamber in said body opening into said box: a door for said
chamber a reservoir in the body opening into said box; ducts leading from said box
onto inwardly inclined distributing shelves in the body; and a laterally projecting
arm on said journal fitted to rotate in said box and raise the lubricant to said ducts
substantially as described.
Third. In a journal-box a body provided with a bushing for supporting it on an
axle journal; a box on said body provided with a door; an oil reservoir leading into
said box; ducts leading from the box onto inclined shelves in the body for distributing
the lubricant onto the journal; and an arm fixed to the outer end of the journal and
rotating in said box, said arm having a forked head whereby the lubricant from the
reservoir may be conveyed to said ducts substantially as described.
Fourth. In a journal-box, a body provided with a bushing bearing on the axle
journal; a circular box on the outer end of said body provided with a door; a
packing chamber below said journal opening into said box; an oil reservoir opening
into said box and provided with an outwardly inclined bottom; ducts leading from
said box onto inwardly inclined distributing shelves in said body; and an arm pro-
jecting laterally from the outer end of said journal and fitted to rotate in said box,
said arm having a forked head; provided with curved prongs whereby oil from the
reservoir may be conveyed to said ducts substantially as described.
Fifth. In a journal-box the axle-journal C, provided with the flange d in combina-
tion with the body A, having the bushing g; the box H on said body; the reservoir G
opening into said box; the inclined shelves 17; the ducts 18, leading from said box
to said shelves and the arm t, secured to said journal, all being arranged to operate
substantially as described.
Sixth. In a journal-box the combination of the axle B; the body A, having the
bushing g, bearing on the journal C; the box H, provided with the inclined bottom i,
and the door p; the partitions h forming packing chamber D, and reservoir G opening
into said box, the door 16 for said chamber; the ducts 18 leading from said box to
inclined distributing shelves in said body and the arm t provided with the forked
head w, substantially as and for the purpose set forth.
Seventh. In a journal box an arm secured to the revolving journal substantially as
and for the purpose set forth.
