page_text: I, GEORGE CROYDON MARKS, of 18, Southampton Buildings, London, W.C.,
Consulting Engineer (being a communication from abroad by Monsieur Gaston
Boutitie, of Bayonne, France), do hereby declare the nature of this invention
to be as follows:-
This invention relates to motor vehicles and has for its object to so provide a
motor vehicle that the motor shall not be subject to the shocks incidental to
the passage of the vehicle over irregular surfaces and so that the gearing shall
be noiseless in operation and in which the construction shall be simple and the
operation effective.
The invention consists in mounting the motor upon a superposed frame
supported upon an under frame by means of springs and in the employment of
belt gear to communicate motion from the motor to the driving mechanism which
belt gear is relatively long.
In carrying the invention into effect in the provision of a motor car an under
frame is provided upon which a second frame is mounted carried upon the under
frame by means of springs. The motor is mounted upon the superposed frame
near the front end of the car and communicates motion to a secondary shaft
mounted in proximity to the rear driving axle. A loose pulley is mounted upon
this secondary shaft upon which the belt may be caused to pass from the adjacent
fixed pulley so as to disconnect the motor. Motion is communicated from the
secondary shaft to the driving axle through differential gear or an equation box
centrally disposed upon the driving axle. The motion may, however, be com-
municated to the driving wheels by the provision of toothed wheels integral
with the hubs of such driving wheels with which toothed wheels pinions provided
upon the extremities of the secondary shaft may gear thereby obviating the
employment of a rotating axle. It will be understood that in the provision of
a motor car as hereinbefore described the shocks incidental to the use of such
cars over rough roads are not communicated to the motor while the belt gear
employed is noiseless and is capable of being conveniently enclosed within a
casing while the employment of a belt relatively long permits of the relative
movement of the driving mechanism of the motor.

page_text: Boutitie, of Bayonne, France), 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 motor vehicles and has for its object to so provide a
motor vehicle that the motor shall not be subject to the shocks incidental to
the passage of the vehicle over irregular surfaces and so that the gearing shall
be noiseless in operation and in which the construction shall be simple and the
operation effective.
The invention consists in mounting the motor upon a superposed frame
supported upon an under frame by means of springs and in the employment of
belt gear to communicate motion from the motor to the driving mechanism which
belt gear is relatively long.
The invention is illustrated in the accompanying drawings in which
Figures 1 and 2 are respectively sectional elevation and plan of the under
frame of a motor vehicle with the improvements applied thereto.
Figure 3 is a plan showing a modification in the driving gear.
In carrying the invention into effect in the provision of a motor car as illus-
trated in the drawings an under frame a is provided upon which a second frame
is mounted carried upon the under frame by means of springs r.
The motor
is mounted upon the superposed frame 6 near the front end of the car and
communicates motion from its driving pulley c by a belt m to a pulley d
on a secondary shaft i mounted in proximity to the rear driving axle h. A
loose pulley is mounted upon this secondary shaft upon which the belt m
may be caused to pass from the adjacent fixed pulley so as to disconnect
the motor. Motion is communicated from the secondary shaft i to the driving
axle h through differential gear or an equation box k centrally disposed upon the
driving axle. The motion may, however, be communicated to the driving
wheels by the provision of toothed wheels n integral with the hubs of such
driving wheels with which toothed wheels or pinions n' provided upon the
extremities of the secondary shaft may gear, as shown in Figure 3, thereby
obviating the employment of a rotating axle. It will be understood that in
the provision of a motor car as hereinbefore described the shocks incidental to
the use of such cars over rough roads are not communicated to the motor while
the belt gear employed is noiseless and is capable of being conveniently enclosed
within a casing while the employment of a belt relatively long permits of the
relative movement of the driving mechanism of the motor.
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:-
The improvements in motor driven vehicles comprising an under frame carried
by the wheels of the vehicle and supporting by means of springs a second frame
on which the body of the vehicle and the motor are mounted the latter trans-
mitting motion to the driving gear by a long belt substantially as hereinbefore
described and illustrated.
