CHARLES B. HOBRON, OF BOERNE, TEXAS, ASSIGNOR OF ONE-THIRD TO
SAMUEL S. EVELAND, OF PHILADELPHIA, PENNSYLVANIA.
ANTIFRICTIO N-BEARING.
SPECIFICATION forming part of Letters Patent No. 603,642, dated May 10, 1898.
Application filed April 7, 1897. Serial No. 631,132. (No model.)To all whom zt may concern:
Be it known that I, CHARLES B. HOBRON,
a citizen of the United States, residing at
Boerne, in the county of Kendall and State
5 of Texas, have invented certain new and use-
ful Improvements in Antifriction-Bearings,
of which the following is a specification.
The object of my invention is to provide an
improved antifriction - bearing for vehicle-
io hubs and the like, my special object being to
provide improved means for affording anti-
friction-bearings for the ends of the hub and
means for excluding dust from the bearings.
In the accompanying drawings, Figure 1 is
15 a view, partly in longitudinal central section
and partly in elevation, of a vehicle-hub and
one end of an axle with my improvements ap-
plied. Fig. 2 is a perspective view of one of
the caps or end pieces employed. Fig. 3 is a
20 perspective view of one of the rings which
surround the journal or arm of the axle.
Fig. 4 is a perspective view of one end of the
sleeve or casing which surrounds the axle.
Fig. 5 is a detail view showing a modified way
25 of excluding dust from the ball-bearings at
the inner end of the sleeve. Fig. 6 is a de-
tail view on an enlarged scale, showing the
preferred way of excluding dust from the ball-
bearings. This figure also shows the man-
30 ner of arranging the balls in the undercut an-
nular groove.
The end of the axle A is formed with a col-
lar B and the journal or axle-arm C. The
end of the axle-arm is screw-threaded at D
35 to receive a nut E. A sleeve or casing F sur-
rounds the journal, and between the casing
and the journal are interposed a series of
rows of balls G and a series of rings II. At
each end of the casing F is arranged an end
40 piece or cap I, each of which is provided with
an annular series of balls J to receive end
thrust and wear and an annular rib K to ex-
clude dust. Each end piece is arranged to
fit in a socket 2 in the end of the casing, and
45 preferably each end piece is formed with
wings, fitting into corresponding recesses k
in the sleeve and projecting therefrom to re-
ceive screw-rods L, which tie the end pieces
at opposite ends of the casing together and
5o extend through the wooden portion of thehub. Where wings are employed, the end
pieces are prevented from turning relatively
to the sleeve; but if the wings were omitted
the end pieces would be free to rotate rela-
tively to the sleeve and relatively to the jour- 55
nal. Each series of balls J is arranged in an
annular undercut groove J' in the end piece,
and the balls are inserted through a passage
1, leading to the rear portion of the groove.
This passage may be stopped by a suitable 6o
plug after the balls have been inserted. The
annular rib K is arranged to enter a corre-
sponding annular groove K' in the collar B
or in the nutE. The arrangement may, how-
ever, be reversed and the groove formed in 65
the end piece and the rib on the collar or on
the nut, as indicated in Fig. 5. Each end
piece is also formed with an annular flange
M, concaved slightly at m to accommodate
the adjacent annular series of balls. 70
In the drawings I have shown four sets of
balls and three rings. The balls are so ar-
ranged as to each have two bearing-points
only, one against the sleeve or casing and one
against the journal The rings have annu- 75
lar grooves h arranged on opposite sides of
the balls; but these grooves are so formed as
to clear the balls-that is to say, the rings do
not press against the balls, nor do the balls
with any wearing pressure press against the 8o
rings, it being desirable that each ball shall
have two bearing-points only, as before stated,
and these points should be on the journal and
on the surrounding casing. Therefore the
grooves at their inner ends terminate in fins 85
h', which project only a short distance under
the balls, and the grooves at their upper ends
are so wide that the rings do not more than
merely touch the balls. In fact, they may be
so arranged that the distance between the 90
outer surfaces or edges of adjacent rings shall
be greater than the diameter of the balls.
The distance between the opposing or adja-
cent fins, however, should be a little less than
the diameter of the balls, so that when the 95
journal is removed the balls shall not drop
out of place. It is likewise true that the dis-
tance between the end ring and the flange M
on each end piece is such as to prevent a
bearing contact, such as to exert a wearing ioo
