Improvements in Under Frames for Road Vehicles.
I, ZDZISLAV MAEVSKY, of No. 38, Vozniesniensky Prospecte Log. Nr. 53, St.
Petersburg, in the Empire of Russia, 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 invention relates to under frames for vehicles in which, in contra distinc-
tion to the arrangements herein before employed, the carrying wheels are not
arranged on both sides of the centre line of the vehicle, but are arranged in the
said centre line itself. In this manner when the load is uniformly distributed,
the vehicle will run with very much more ease, so that a considerable saving of
power will be effected in the propulsion or traction thereof.
The invention therefore consists in the arrangement of the carrying wheels of
a vehicle in the centre line while for the purpose of propelling the vehicle in the
case of motor cars for example and for providing lateral support in the case of
oscillations there are arranged laterally on the centre line of the vehicle additional
wheels which may, however, be raised and thus be rendered inoperative.
The accompanying drawing illustrates the new under frame for vehicles in one
arrangement which is shewn by way of example. Figure 1 being a side eleva-
tion, and Figure 2 a front elevation of the same.
The longitudinal frame a upon which the bottom of the vehicle is fixed is
provided for the purpose of receiving the bearings for the front and hind wheels c
and d with suitable forks or hornplates and . The construction of the
frame a, as also its attachment to the bottom of the vehicle, and the construction
of the forks or hornplates c and d may be designed suitably according to the
size and weight of the vehicle. For the purpose of laterally supporting the
vehicle lateral wheels must be provided which are to be constructed and arranged
preferably in such a manner that they shall be capable of being raised or lowered
by an operator on the vehicle itself.
In the arrangement shewn here the axle f of these supporting wheels e is
arranged by way of example with a bearing in a forked bent lever g h which is
pivotted at i, and which can be operated and fixed by depressing the foot plate k.
The supporting wheels are lowered or raised by the driver of the vehicle according
to requirement, and the foot plate & may be retained in its lower position by means
of a spring catch . In this case also the construction of the supporting wheels
and of the lifting device may be designed according to the requirements of each
case.
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. An under frame for vehicles in which the carrying wheels are arranged in
al whilst for the purnac

page_text: of supporting the vehicle in the case of oscillations, there are provided laterally
supporting wheels e which are capable of being uplifted, substantially as described.
2. A particular form of construction of an under frame for vehicles in which
the lateral wheels e are not arranged to be capable of being uplifted, substantially
as described.
