Improved Method of Constructing, Mounting, and Arranging the
Under Frame and Driving Appliances of Electric and other
Road Motor Cars, and in Means or Apparatus for Reducing
Vibrations and Oscillations, and to Facilitate Ease of Action
in Starting such Cars.
I, HAZELWOOD CARMONT, of Helmsdale, Kingston on Thames, Surrey, Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to a certain improved method of constructing, mounting,
and arranging the under frame and driving appliances of electric and other road
motor cars and in means or apparatus for reducing vibrations and oscillations and
to facilitate ease of action in starting such cars.
For the purpose of my invention, I take the body of an ordinary omnibus, cab,
or other four wheeled vehicle and so construct the back under frame and arrange
the parts that those wheels can be turned within certain angles for guiding
purposes, said under frame being provided with a cranked-axle between which and
the body when mounted upon it said under frame can turn, the operation being effected
from the front by a hand wheel and rods or chains. The cranked axle is movable
circularwise upon a broad base to produce steadiness and to obviate vibrations and
oscillations of the body while the vehicle is travelling, and springs are fitted to
give ease of motion and comfort to the passengers or occupants.
The springs of the hind wheels are preferably of the long plate kind affixed from
about the centre of the body to the rear portion of the front under frame which
is, in a sense, rigid and has no independent turning action, it is supported or hung
from springs fitted to the lower part of the front axle which is also cranked, the
upper part of the cranked axle having the usual springs affixed and on which the
front body rests.
The projecting fore part of the front under frame serves as a platform for power
motor and is in connection by wheels and chains or other gear with the front wheels
for driving them.
Bands on the periphery portions of these wheels have each an annular groove
or grooves for the reception of coiled springs and chocks, so that the power when
first applied is through the chocks and thence through the coiled springs to effect
a gradual start, the springs being kept in tension during the running, and rebound
to bring the vehicle gradually to a standstill when the power is shut off, thus
obviating concussions particularly at starting which is now so much complained of
by riders of motor cars.
It will be gathered from the foregoing that my under frame is a structure in
itself and the bodies of existing vehicles can be fitted thereon, so that there need
be no change in the appearance of public vehicles except that they are horseless.

Improved Method of Constructing, Mounting, and Arranging the
Under Frame and Driving Appliances of Electric and other
Road Motor Cars, and in Means or Apparatus for Reducing
Vibrations and Oscillations, and to Facilitate Ease of Action
in Starting such Cars.
I, HAZELWOOD CARMONT, of Helmsdale, Kingston on Thames, Surrey, 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 a certain improved method of constructing, mounting,
and arranging the under frame and driving appliance of electric and other road
motor cars, and in means or apparatus for reducing vibrations and oscillations and
to facilitate ease of action in starting such cars.
For the purpose of my invention, I take the body of an ordinary omnibus, cab,
or other four wheeled vehicle and so construct the front under frame and arrango the
parts that those wheels can be turned within certain angles for guiding purposes.
The front under frame serves to receive a power motor and is in connection by
wheels and chains or other gear with the front wheels for driving them.
Bands on the periphery. portions of theso wheels have each an annular groove
or grooves for the reception of coiled springs and chocks, so that the power when
first applied is through the chocks and thence through the coiled springs to effect
a gradual start, the springs being kept in tension during the running and rebound
to bring the vehicle gradually to a standstill when the power is shut off, thus
obviating concussions particularly at starting which is now so much complained of by
riders of motor cars.
It will be gathered from the foregoing that my under frame is a structure in
itself and the bodies of existing vehicles can be fitted thereon, so that there need
be no change in the appearance of public vehicles except that they are horseless.
My invention is represented in the annexed drawings.
Figure 1 side elevation of an ordinary omnibus.
Figure 2 front end of same.
Figure 3 under plan.
Figure 4 inside view of one of the front wheels with the helical spring in an annular
channel of a box secured to the wheel.
Figure 5 elevation of hind cranked axle of the usual construction but with plates
within which a roller can move, said roller being on the end of a spring leading
from the rear of the front under carriage.
Figure 6 elevation of the foot clutch incchanism for starting and stopping the
vehicle.
A is the body of the vehicle. B, C, the front and hind wheels respectively.
D, is a box or receptacle in which a motive power engine can be placed for operating
the chain gear wheels E, E, on the shaft F on which shaft the clutches G, G, are
slidingly keyed to rotate therewith, the chain gear wheels E, E, being loosely mounted
on the shaft F for rotation only when the clutches G, G, are thrown into contact
with the clutch blocks H, H, of the chain gear wheels E, E, this being effected by
pressure on the foot plate 1 secured to the right and left hand screw threaded
shaft J with which the collars K, K, also screw threaded are respectively in gear.
These collars K, K, held in forks L, L, of levers M, M, are pivoted on lugs N, N,
fixed to the under box D. The rear of the box D has a plate or laminated spring
extension P affixed, and the free end of this spring carries a roller Qriding
between straps R, R, secured to the hind axle S by clips T, T, said straps being of
segmental form struck from the perch bolt U of the vehicle. The chains V, V, of

page_text: the gear E, E, are led round toothed rings W, W, which have motion on the front
wheels B, B, by their connection to ring frames X, X, which are secured to the spokes
of the ordinary front wheels B, B, the rings W, W, and the frames X, X, each
forming an annular chamber in which coiled springs Y, Y, are retained and are capable
of being compressed by the onward travel of the wheels B, B, and the chocks Z, Z,
of the rings W, W, against the resistance of the fixed chocks a, a, of the frames X, X,
there being supplementary springs b, b, between the chocks Z and a as buffer springs
to resist back pressure when the chocks are approaching each other.
The front part of the body of the vehicle has a frame c affixed and this has a
segmental toothed plate d as part thereof, into which a pinion e gears, said pinion being
secured by brackets f, f, on a platform g and front of the box D respectively, the
turning of said pinion e by the hand wheel h and spindle i effecting the steering or
guiding of the vehicle.
The platform g upon which the attendant stands has the foot plate I projecting
upwardly so that the attendant has only to press upon it to put the clutches G, G, into
gear with the blocks H, H, of the front wheels, the motive power being already and
constantly in motion for propulsion purposes.
On the removal of the attendant's foot, the spring; causes the foot plate I to
spring up, and in doing this the foot plate I which is affixed to the shaft reverses
the rotation of the collars K, K, and takes the clutches G G out of gear, the shaft F
continuing its rotation from the prime mover arranged within the box D.
In order that a motive machine in the carrier box D be kept separate from the
vehicle body A, I employ a deep cranked axle k for the front wheels B, B, and provide
springs 1, 1, between said axle k and box D to prevent the pulsations of the engine in
the box D being communicated to the occupants of the vehicle, other springs m, m,
being provided between the transom bar and the front axle k, so that oscillations from
unevenness of the roadway are absorbed by the ordinary springs m, m, and the
oscillations and vibrations communicated to the box Ď are absorbed by the
springs l, l.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Providing the front of a four wheeled vehicle with a projecting frame c, the
edge face of which is a toothed rack d for a gear pinion e on a swing round under
fore carriage, said frame being horizontally arranged between a foot or platform g and
motor box D, as and for the purposes described.
2. Providing a four wheeled vehicle with an under carriage formed as a box D
for containing a power engine, said box D being supported by springs 1, 1, on the
same axle as those supporting the body of the vehicle, as specified.
3. Connecting the front under carriage or box D of a four wheeled vehicle by
a spring P to a segmental frame R affixed to the rear axle S, said spring P having
a roller Q to slide or move as a guide in said frame R, as described.
4. In a four wheeled vehicle so fitting. a ring band X that it in conjunction
with an otherwise loose ring W having teeth on its periphery and enclosing a
spring Y may form the means of applying the power of a motor engine to the front or
other travelling wheels, as and for the purposes specified.
5. In a power driven four wheeled road vehiclo, providing a double or two separate
clutches G, G, on a main driving shaft for simultaneous operation from a reversely
threaded shaft under direction of a foot plate I, as shown at Figure 6 of the
annexed drawings.
