I, JAMES SWAN, of 622, Buchanan Street, Topeka, Kansas, U.S.A., Inventor,
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to improve the construction of journal bearings,
more especially the means for securing a Babbitt metal or similar lining to the
same and to provide a simple and comparatively inexpensive device whereby
such a lining will be securely fastened to a journal bearing and will be prevented
from becoming loose and displaced.
"
brasses"
By this invention, those parts of a journal-bearing known as the
have their concave inner surfaces cast or otherwise formed with recesses at their
sides and ends, and also one or more apertures extending therethrough; said
apertures being countersunk on the outer surface of the brasses.
Suitable lugs project upwardly from the bottoms of the recesses and are adapted
to be bent over to form hooks.
When Babbitt or like metal, in a molten state, is poured into the brasses it
enters the recesses and forms around the hook shaped lugs, and also enters the
apertures through the brasses; being retained therein by the countersunk portion
thereof.

Improvements in Journal Bearings.
I, JAMES SWAN, of 622, Buchanan Street, Topeka, Kansas, U.S.A., Inventor,
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 follow-
ing statement:-
-
The invention relates to improvements in journal bearings.
The object of the present invention is to improve the construction of journal
bearings, more especially the means for securing a Babbitt metal or similar lining
to the same, and the provide a simple and comparatively inexpensive device
whereby such a lining will be securely fastened to a journal bearing and will be
prevented from becoming loose and displaced.
The invention consists in the construction and novel combination and arrange-
ment of parts, as hereinafter fully described, illustrated in the accompanying
drawings, and pointed out in the claim hereto appended.
In the drawings, Figure 1 is a longitudinal sectional view of a journal box
229

page_text: provided with a journal bearing constructed in accordance with this invention,
Fig. 2 is a perspective view of the journal-bearing preparatory to receiving the
soft-metal lining and before the lugs or projections are bent downward or inward
to their engaging position. Fig. 3 is a similar view, the lugs or projections being
bent inwards to form hooks. Fig. 4 is a perspective view shewing the journal
bearing complete. Fig. 5 is a transverse sectional view of the same.
Like numerals of reference indicate corresponding parts in the several figures
of the drawings.
1 designates a journal bearing or brass arranged within a journal box 2 and
interposed between the journal of an axle 3 and a key or wedge 4 in the usual
manner.
The journal bearing or brass is provided at its inner or lower concave face with
a lining 5, of Babbitt metal or other suitable material, and in order to fasten the
same securely in place and prevent it from becoming loose when subjected to
severe usage the journal bearing has a central opening 6 and is provided with
side and end recesses 7 and 8, in which are arranged tapering projections or
lugs 9 and 10, located at the sides and ends of the journal bearing or brass, as
clearly shewn in Figs. 2 and 3 of the accompanying drawings. The recesses or
gutters 7 and 8, which are located at opposite sides of the bearing or brass and
which extend across the ends, are substantially triangular in cross section, and
the projections or lugs, which are malleable, are formed on the inner faces or
walls and are adapted to be bent in the direction of the outer walls to form
hooks. The Babbitt metal or other soft-metal lining is applied to the journal
brass or bearing in a liquid state, and the metal runs around and settles in the
recesses or gutters. When the metal becomes cool and hard it is firmly inter-
locked with the journal bearing or brass and is securely held by the hook-shaped
projections or lugs. The opening 6, which extends entirely through the body
portion of the bearing, is enlarged and flared at the top to form a head for the
core 11, of Babbitt metal, moulded in the opening.
The invention has the following advantages:-The journal bearing or brass
is simple and comparatively inexpensive in construction, and the means for fasten-
ing the Babbitt metal lining are efficient, easily constructed, and capable of
enabling the lining to obtain a firm hold on the concave face of the body portion
of the journal brass or bearing.
The body portion of the journal bearing or brass consists of a single piece of
metal, and the soft-metal lining is secured to the body by simply pouring it on
the same without employing any fastening devices, such as rivets or the like.
Changes in the form, proportion, and minor details of construction may be
resorted to without departing from the spirit or sacrificing any of the advantages
of the invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is―
A journal bearing or brass comprising a solid body portion consisting of a
single piece of metal and provided at opposite sides with narrow gutters formed 4
by recessing the solid body portion, the malleable projections or lugs formed integral
with the body portion and located at the sides of the recesses and adapted to be
bent over the latter to form hooks, and a lining of soft material applied to the
body portion in a molten condition, and having the projections or lugs embedded
in it, whereby it is retained in the body portion, substantially as described.
