I, FERDINAND BOSSHARDT, of the Firm of F. Bosshardt & Co., of 4, Corporation
Street, Manchester, in, the County of Lancaster, Patent Agents, do hereby declare
the nature of this invention, which has been communicated to me from abroad by
Kugler & Co., of Zürich, in the Republic of Switzerland, to be as follows:-
This invention relates to an improved construction of ball bearing adapted to
receive axial as well as lateral thrust in such a manner that the balls which
receive the axial thrust are allowed a slight lateral movement and any lateral
thrust will be at once received by the side balls.
On annexed drawing Figs. 1-8 shows various forms of my improved con-
struction of ball bearing. The grooves for the balls are formed in the bushes a, a
secured to the axle. Each bush a has a flange a¹ and a groove a therein in
which run the side balls b adapted to receive the lateral thrust. The said side
balls are retained in their grooves by the inner ends of rings c, c employed
around the flanged bushes a, a, and secured to the hub B. The grooves co, a°,
which are formed parallel with the axle and in which the balls d run which
receive the lateral thrust, are partly formed in the flanged bushes a, a and
partly in the rings c, c and permit a slight lateral movement of the balls & which
causes any lateral thrust to be at once received by the side balls. This exceed-
ingly simple construction permits a uniform execution of the various uses in
connection with former arrangements where side balls are employed.
described construction has also the advantage of permitting the placing of the
ball bearing around the axle or axle pin completely fitted together.
The
Figs. 1 & 2 show my improved bearing in the form as applied to tram cars.
As previously described it has two bushes a, a, the flanges a¹ of which abut
against each other, Fig. 1, so as to cause the lateral thrust to be received in the
middle of the bearing, whilst in the arrangement shown in Fig. 2 the flanges a¹
of the bushes a, a, are positioned at each end and lateral thrust is also imme-
diately taken up by the side balls. The ball bearing is secured together by
means of the nut e
Fig. 3 shows a ball bearing suitable for road vehicles which is constructed
similarly to that described with reference to Fig. 2 with this difference that
between the two bushes a, a, a chamber f is provided for the purpose of bringing
the axial thrust and lateral thrust balls further apart from each other.
Fig. 4 shows a longitudinal section of a ball hearing suitable for rolling stock.
Fig. 5 is a cross section and Fig. 6 a cross section of the flanged bush of the same,
the flange a', the grooves therein and balls b being shown in elevation.
Figs. 4 & 5 show how the balls d which receive the axial thrust are placed
into their grooves, i.e. after the side balls 6 have been placed into their grooves
and the rings c, c over the flanged bushes a, a, they are introduced through an
opening in the hub B which afterwards is closed by means of a plug g.
Fig. 7 shows a longitudinal section of a ball bearing adapted for shafting

is similar to that described with reference to Fig. 1.

Improvements in Ball Bearings,
I, FERDINAND BOSSHARDT, of the Firm of F. Bosshardt & Co., of 4, Corporation
Street, Manchester, in the County of Lancaster, Patent Agents, do hereby declare
the nature of this invention, which has been communicated to me from abroad by
Kugler & Co., of Zürich, in the Republic of Switzerland, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention relates to an improved construction of ball bearing adapted to
receive axial as well as lateral thrust in such a manner that the balls which
receive the axle thrust are allowed a slight lateral movement and any lateral
thrust will be at once received by the side balls.
Figs. 18, of the drawings filed with my Provisional Specification, show
various forms of my improved construction of ball bearing. The grooves for
the balls are formed in the bushes a, a secured to the axle. Each bush a has a
flange a¹ and a groove a therein in which run the side balls b adapted to receive
the lateral thrust. The said side balls are retained in their grooves by the inner
ends of rings c, c employed around the flanged bushes a, a, and secured to the
hub B. The grooves co, a, which are formed parallel with the axle and in
which the balls d run which receive the lateral thrust, are partly formed in the
flanged bushes a, a and partly in the rings c, c and permit a slight lateral move-
ment of the balls d which causes any lateral thrust to be at once received by
the side balls. This exceedingly simple construction permits a uniform
execution of the various uses in connection with former arrangements where
side balls are employed. The described construction has also the advantage of
permitting the placing of the ball bearing around the axle or axle pin completely
fitted together.
Figs. 1&2 show my improved bearing in the form as applied to tram cars.
As previously described it has two bushes a, a, the flanges a' of which abut
against each other, Fig. 1, so as to cause the lateral thrust to be received in the
middle of the bearing, whilst in the arrangement shown in Fig. 2 the flanges a¹
of the bushes a, a, are positioned at each end and lateral thrust is also imme-
diately taken up by the side balls. The ball bearing is secured together by
means of the nut e.
Fig. 3 shows a ball bearing suitable for road vehicles which is constructed
similarly to that described with reference to Fig. 2, with this difference that
between the two bushes a, a, a chamber f is provided for the purpose of bringing
the axial thrust and lateral thrust balls further apart from each other.
Fig. 4 shows a longitudinal section of a ball bearing suitable for rolling stock.
Fig. 5 is a cross section and Fig. 6 a cross section of the flanged bush of the
same, the flange a², the grooves therein and balls 6 being shown in elevation.
Figs. 4 & 5 show how the balls d which receive the axial thrust are placed into
their grooves, i.e. after the side balls 6 have been placed into their grooves and
the rings c, cover the flanged bushes a, a, they are introduced through an opening
in the hub B which afterwards is closed by means of a plug 9.

page_text: Fig. 7 shows a longitudinal section of a ball bearing adapted for shafting
and Fig. 8 is a cross section of half of the same. This construction of bearing
is similar to that described with reference to Fig. 1.
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:-
1st. A ball bearing having ball races adapted to take up lateral and axial
thrust, consisting of two bushes arranged concentrically,, one of which bushes
has a flange for the reception of lateral thrust and the axial balls being arranged
in a groove between the said two bushes and the lateral balls in an annular
groove between the said flange and the face of the other bush, all substantially
as set forth.
2nd. The combination, with an annularly-flanged axle-sleeve, provided on its
circumference and on that side of its flange nearer and adjacent to the main body
of the sleeve with annular grooves, of an exterior casing sleeve or bushing pro-
vided with an interior annular groove, said casing-sleeve or bushing being placed
over the axle-sleeve with its groove in, register with the circumferential groove of
the axle sleeve, a series of halls arranged in the groove of the flange and running
in contact with the end of the casing-sleeve adjacent to said flange, and a series
of balls arranged in the registering grooves of the axle-sleeve and the casing-
sleeve, substantially as set forth.
3rd. The combination, with an axle or shaft, and an annularly-flanged sleeve
placed thereon, said sleeve being provided on its circumference with an annular
groove and on that side or face of its flange nearer and adjacent to the main
body of the sleeve with an annular groove, of a casing, a sleeve or bushing fixed
in said casing and provided with an interior annular groove in register with
the circumferential groove of the axle-sleeve, a series of balls arranged in the
annular groove, and running in contact with the end of the casing-sleeve adjacent
to the flange, and another series of balls arranged in the registering grooves of
the axle-sleeves and the casing-sleeve, substantially as set forth.
4th. The combination, with an axle or shaft, and two annularly-flanged sleeves
placed on said shaft or axle with the flanges abutting, said sleeves having, in
their circumferences, annular grooves, and said flanges having, in their faces,
annular grooves, of a casing, and sleeves fixed in the casing, over the axle-sleeves
and being provided with annular grooves, and the flanges of the axle-sleeves being
arranged opposite to the inner ends or to the outer ends of the casing-sleeves,
balls arranged in the grooves of the flanges, and balls arranged in the register-
ing grooves of the axle and casing-sleeves, substantially as set forth.
