page_text: I, MATHIEN FOIDART, of 63, Quai du Hoinant, Brussels, Belgium, Engineer,
do hereby declare the nature of this invention to be as follows:-
The present invention consists in an improved ball bearing provided with cer-
tain arrangements which render it especially applicable to vehicles intended for
heavy loads and a high speed.
The bearing consists essentially of a smooth sleeve mounted loosely upon the
axle journal or upon any suitable shaft or axis. The sleeve is provided at one
extremity with a shoulder or collar whilst the other extremity is recessed to
receive the projections or tenons of a plate or disc which is applied against the
end of the journal and is keyed to it by means of a key which engages in a
suitable groove or key way in the said journal. A buffer acted on by a spring
serves to keep the plate or disc against the end of the journal.
The stem of the above-mentioned buffer and the spring which surrounds it
are located in a recess or chamber cast or formed on a cap or plug screwed into
the end of the axle box or casing.
This cap or plug also serves to maintain in place the outer sleeve which bears
at its other end against the inner shoulder on the axle box.
The arrangement of the retaining plate or disc and of the impact buffer has
for its object, when the bearing or axle box is applied to vehicles, the dispensation
of any longitudinal keying of the journal and of all rigid connections by means
of screws or otherwise between the said journal and the box, connections which
are liable to fracture or disconnection by reason of the vibrations and the lateral
movements of the vehicle, more especially in the case of tramway cars.
my arrangement the impact is taken up by the spring of the buffer and there-
fore in no way interferes with the retaining plate or disc. The tendency (which
is very slight) of the cap or plug to become unscrewed can be counteracted by
means of a screw fitted in the oil hole.
In
On the sleeve are mounted freely rings or loose collars or washers between
each of which is placed a set of bails. The first ring or loose collar or washer
towards the inside rests against the shoulder or fixed collar, whilst the last,
exteriorly, is, as are all the others, held in place by the ends of the tenons of
the plate or disc. The working balls are kept at a distance the one from the
other by means of intermediate balls of smaller diameter.
The bearing box is provided at the front end with an oil hole formed in the
axle box and in the cap or plug, by means of which the lubricating material is
introduced into the bearing box where it occupies the lower portion of this
latter, so that the balls are continually oiled during the travelling movement.
I have found that experience has amply demonstrated that the rings or loose
collars or washers are much more advantageous than annular grooves inasmuch as
they prevent the balls from deviating from their circular course or race.
The intermediate balls, have, moreover, the advantage of doing away with the

page_text: friction between the main balls, and in consequence of considerably diminishing
the general friction.
The ball bearing such as has been herein above described is especially applicable
to vehicles, and to heavy loads.
Dated this 30th day of November 1898.

I, MATHIEN FOIDART, of 63, Quai du Hainairt, Brussels, Belgium, Engineer,
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:-
This present invention consists in an improved ball bearing provided with cer-
tain arrangements which render it especially applicable to vehicles intended for
heavy loads and a high speed.
This bearing is illustrated in the annexed drawing in which,
Fig. 1, is a longitudinal section through the ball bearing.
Fig. 2, is a transverse section on the line -y Fig. 1.
Fig. 3, is a view of the tightening plate.
Fig. 4, is a longitudinal section of a bearing with intermediate balls.
Fig. 5, is a transverse section on the line V-Z Fig. 4.
The bearings consists essentially of a smooth sleeve A mounted loosely upon
the axle journal C (or upon any suitable shaft or axis).
The sleeve A is provided at one extremity with a shoulder or collar a whilst
the other extremity is recessed to receive the projections or tenons 6 of a plate or
disc B which is applied against the end of the journal C and is keyed to it by
means of the key which engages in a suitable groove or key way in the said
journal. A buffer D acted on by a spring & serves to keep the plate or disc B
against the end of the journal.
The stem of the above mentioned buffer and the spring which surrounds it are
located in a recess or chamber e cast or formed on a cap or plug E screwed into
the end of the axle box or casing F.
This cap or plug also serves to maintain in place the outer sleeve G which bears
at its other end against the inner shoulder on the axle box F.
The arrangement of the retaining plate or disc and of the impact buffer has
for its object, when the bearing or axle box is applied to vehicles, the dispensation
of any longitudinal keying of the journal and of all rigid connections by means
of screws or otherwise between the said journal and the box, connections which
are liable to fracture or discnnection by reason of the vibrations and the lateral
movements of the vehicle, more especially in the case of tramway cars.
In my
arrangement the impact is taken up by the spring of the buffer and therefore in
no way way interferes with the retaining plate or disc.
The tendency (which is very slight) of the cap or plug E to become unscrewed
can be counteracted by means of a screw fitted in the oil hole h.
On the sleeve A are mounted freely rings or loose collars or washers between
each of which is placed a set of balls g. The first ring or loose collar or washer
towards the inside rests against the shoulder or fixed collar a, whilst the last,
exteriorly, is, as are all the others, held in placed by the ends of the tenous b of
the plate or disc B.

page_text: Figs. 4, and 5, illustrate a ball bearing identical with, that hereinabove
described, but wherein the working balls are kept at a distance the one from the
other by means of intermediate balls g₁ of smaller diameter.
The bearing box is provided at the front end with an oil hole h formed in the
axle box F and in the cap or plug E, by means of which the lubricating material
is introduced into the bearing box where it occupies the lower portion of this
latter, so that the balls are continually oiled during their travelling movement.
I have found that experience has amply demonstrated that the rings or loose
collars or washers are much more advantageous than annular grooves inasmuch
as they prevent the balls from deviating from their circular course or race.
The intermediate balls have, moreover the advantage of doing away with the
friction between the main balls, and in consequence of considerally diminishing
the general friction.
The ball bearing such as has been hereinabove described is especially applicable
to vehicles, and to heavy loads.
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:-
1. A ball bearing characterized by a sleeve to receive the balls mounted freely
upon the axis and held in position thereon by means of a plate or its equivalent,
having tenous engaging in recesses in the sleeve, and held against the extremity
of the axis, where it is keyed, by an arrangement capable of giving.
2. A. ball bearing characterized by a sleeve mounted upon the axis, rings
washers or collars mounted upon the said sleeve, balls between each of the said
rings or collars, and an arrangement for holding the balls and the rings, collars
or washers in position.
3. A ball bearing characterized by a sleeve mounted on the axis, rings, collars,
or washers mounted on the said sleeve, working or main balls between each of
the said rings, collars, or washers intermediate balls of smaller diameter to keep
the working or main balls apart, and an arrangement for keeping the balls and
the rings or washers in place.
