motion. A circular groove is preferably formed in the disc where it bears on the
ball, the cross section of this groove being a segment of a circle of a somewhat larger
radius than the ball.
The discs themselves may have on their axes collars running on anti-friction balls
at their bearings, these balls being kept apart by a ring with holes or slots one for
each ball.
For driving a vehicle mounted as above described the discs that rest on the balls
may have teeth to gear as bevel-wheels with those on a horizontal driving shaft.

We, ALOIS MARY LEINWATHER of 1II Wasergasse 32 Engineer and Doctor
HEINRICH GLASER of I Franzenoring 22 Lawyer both of Vienna in the Austrian
Empire 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 :—
According to this invention discs are mounted under the vehicle or moving body
on axes perpendicular to the plane of motion. Bencat each disc at one side a ball
is held loosely in a ring fixed to the. vehicle. While the vehicle or other body
advances the discs revolve on their respective balls which roll along the plane of
motion..
The dises themselves may have on their axes collars running on antifriction balls
at their bearings these balls heing kept apart by a ring with holes or slots one for
each ball.
For driving a vehicle mounted as above described the discs that rest on the balls
may have teeth to gear as bevel wheels with those on a horizontal driving shaft.
The vehicles may have brakes arranged to act on the road or ground these heing
arms or levers kept usually raised and lowered when the vehicle is to be retarded:
or arrested.
Figure 1 of the accompanying drawings is a part plan partly in section of a car
embodying this invention.
Figure 2 is a part longitudinal section thereof.
Figure 3 is a partial end elevation of the car.
Figure 1 is a sectional side elevation and
Figure 5a front elevation of a supporting ball and the parts connected therewith.
Figure 6 is a plan of the ball and the sliding frame by which it is surrounded.
Figure 7 is a plan of one of the plates for the bearings of the discs.
Figure 8 is a plan of the ring retaining the anti-friction balls.
Figure 9 is a plan of a disc.
C
on
" is one of the longitudinal girders of a car frame adapted to be supported on
balls b. care discs parallel to the plane of motion mounted free to revolve, *the
underside of the girders a their journals with coned ends having bearings in
plates & bolted to the girders-e are antifriction balls which are interposed between
the upper surface of the discs c and the under surface of the bearing plates d and are
kept in position in holes e² of a ring e¹ which fits the journal c¹ resting on its
shoulder c³.
Beneath each disce on one side of its axis is the supporting ball which is kept in
position by a frame loosely surrounding the ball and having extending down from
it inclined guard plates 1 by which the ball is kept from slipping should the vehicle
be lifted from the ground.

page_text: In order that the balls b may be capable of a certain amount of lateral displacement
to accommodate themselves to inequalities of the road the frames are free to slide
in guides 9 which are suspended from the girders a by hangers g'. The lateral
displacement of the frame foutwards is limited by a lip and the displacement of the
ball towards the axis of the disc c is limited by a central conical boss c*.
The supporting balls b may run upon a road bed or upon a grooved rail as shown
in Figure 5.
For traction there are two rods one extending from each end to the middle of the
vehicle these rods having their ends screw-threaded and connected by a nut j by
which they can be tightened up.
They are guided in brackets & between which and the nut are traction springs l.
At each end of the car is a buffer consisting of a cross-head m faced with sheet
steel mand moveable on bolts m² on which are rubber cushions n interposed between
the crosshead and the front bar a' of the frame.
In the middle of an elongated recess m³ of the crosshead m the draw bar i is jointed
the coupling link o by a bolt o'
The discs c. may be beveled as shown in figures 4 and 5 and provided with teeth to
gear with wheels driven by a motor on the car.
The brakes may be arranged to act on the road or rails as shewn in Figures 1. and 2.
where P is a brake lever of which there is one at each side of the car they are
pivotted at p and are connected by a rod p² 3 being the rod by which the brake
levers can be raised or lowered. There are two sets of the levers p those of the one
set directed forwards as in Figure 2 those of the other directed backwards. By
lowering the forward lovers, the vehicle may be suddenly stopped and it may be more
gradually stopped by lowering the other levers.
What we claim is :-
1. On a vehicle the combination of dises mounted to revolve on axes perpendicular
to the plane of motion with balls arranged in a frame one beneath each disc on one
side of its axis substantially as and for the purpose set forth.
2. In combination with the discs referred to in the preceding claim antifriction
balls interposed between them and the bearing plates on the car frame substantially
as and for the purpose described.
3. The construction of the discs above referred to as bevil wheels capable of being
driven by a motor on the vehicle.
