I, THE HONOURABLE REGINALD THOMAS DUDLEY BROUGHAM, of 22A, Dorset
Street, Portman Square, in the County of Middlesex, do hereby declare the nature
of this invention to be as follows:
The object of this invention is mainly to substitute rolling for sliding friction
in the locking or undercarriages of vehicles.
To effect this the rims of the two rings or wheels of the locking or undercarriage
which are concentric and one above the other are each formed of angle iron section
and between them they enclose an annular space approximately square in cross
section-the rim of one wheel forming the top and one side of the square and the
rim of the other wheel forming the bottom and other side of the square. Into
this annular space is inserted a loose ring carrying a series of rollers some of the
rollers are on horizontal axes the remainder of the rollers are on vertical axes.
The rollers on the horizontal axes keep the two wheels slightly apart from one
another and the rollers on the vertical axes keep them concentric. A bolt
passing down through a hollow stem which extends downwards from the centre
of the upper wheel and through a cross bar forming part of the lower wheel holds
the two wheels from separating from one another.
The rollers on the horizontal axes are conical radiating to a point at the centre
of the ring the surfaces of the rims of the two wheels which bear against them
are correspondingly coned.
The ring is formed as a hollow square in cross section-the horizontal axes of
the one set of rollers form connecting pins holding together two concentric rings
one smaller than and within the other. The vertical axes of the other set of
rollers hold two other rings or sections of rings against the upper and under
edges of the two first mentioned rings. The diameter of the rollers is slightly
greater than the width or depth of the ring so that the rollers project through
the sides and top and bottom of the ring and keep the ring from coming into
contact with the rims of the two wheels.
The lower or locking wheel is attached to the cross bar to which the fore axle
is secured by interposed springs. The upper wheel is fixed to the underside of
the fore part of the vehicle. The lower or locking wheel may be formed as a
toothed wheel around its circumference for a worn or toothed wheel worked by
steering mechanism to gear into.

Electrical and other Motor Vehicles.
I, THE HONOURABLE REGINALD THOMAS DUDLEY BROUGHAM, of 22A, Dorset
Street, Portman Square, in the County of Middlesex, do hereby declare the nature
of this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement:-
-
The object of this invention is mainly to substitute rolling for sliding friction
in the locking or undercarriages of vehicles.
To effect this the rims of the two rings or wheels of the locking or undercarriage
which are concentric and one above the other are each formed of angle iron section
and between them they enclose an annular space approximately square in cross
section the rim of one wheel forming the top and one side of the square and the
rim. of the other wheel forming the bottom and other side of the square. Into
this annular space is inserted a loose ring carrying a series of. rollers some of the
rollers are on horizontal axes the remainder of the rollers are on vertical axes.
The rollers on the horizontal axes keep the two wheels slightly apart from one
another and the rollers on the vertical axes keep them concentric. A bult
passing down through a hollow stem which extends downwards from the centre
of the upper wheel and through a cross bar forming part of the lower wheel holds
the two wheels from separating from one another.
Figure 1 of the drawings annexed is a vertical section of a locking or under-
carriage for a vehicle formed in the above way. Figure 2 is a plan one half in
section of the same. Figure 3 is a vertical section and Figure 4 a plan on a
larger scale taken through one of the conical rollers. Figures and 6 are similar
views taken through one of the horizontal rollers.
A is the rim of angle iron form of the upper wheel A. B the rim of the
lower wheel B. C is the ring inserted into the annular space enclosed between
the rims of the two wheels. D are the horizontal rollers which keep the wheels A
and B concentric and E are the vertical rollers which keep the two wheels at a
slight distance apart from one another. F is the bolt which keeps the two
wheels from moving away from one another. The rollers E are, as shown made
conical radiating to a point at the centre of the ring C-the surfaces of the rims
of the two wheels A and B which bear against them are correspondingly coned.
The ring C is formed as a hollow square in cross section. It is made up of two
concentric rings one smaller than and within the other held together as shown
by the horizontal axes of the rollers E and of two other rings or sections of rings
held against the upper and under edges of the two first mentioned rings by the
vertical axes of the rollers D. The diameter of the rollers is slightly greater than
the width or depth of the hollow ring C so that the rollers project through the
sides and top and bottom of this ring and keep the ring from coming into contact
with the rims of the two wheels A and B.
The lower or locking wheel B is to be attached to the cross bar to which the
fore axle of a vehicle is secured by interposed springs. The upper wheel A is to
be fixed to the underside of the fore part of a vehicle. G is a toothed wheel
which may be formed around the outer circumference of the rim B of the
wheel B for a worm or toothed wheel worked' by steering mechanism to gear into.
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 roller bearing locking or swivelling undercarriage composed of two con-
centric wheels one above the other and having their rims of angle iron form-the

page_text: two rims enclosing an annular space into which a ring carrying horizontal
and vertical rollers is inserted-the horizontal rollers being made conical and
serving to keep the two wheels apart and the vertical rollers serving to keep them
concentric.
2. A roller bearing locking or undercarriage constructed substantially as here-
in before described and illustrated in the drawings annexed.
