Improvements in Driving Mechanism for Axles of Motor-cars, Cycles,
and for like Purposes.
I, THOMAS WILLIAM NAYLER, of Friar Street, Hereford, in the County of
Hereford, Engineer, do hereby declare the nature of this invention to be as
follows:-
-
This invention relates to an improved form of driving mechanism used upon
motor-cars and for like purposes in which a resilient hub or spring boss is employed
with suitable washers and couplings for allowing vibration of the axle of the
vehicle to be effected without interfering with the driving arrangements of the
mechanism or motor employed in connection with the vehicle.
In carrying my invention into effect I mount a spur or other wheel upon a
hollow bush or sleeve which is carried upon the axle or other driving shaft of the
vehicle, and I interpose between the inner portion of the bush and the outer
diameter of the axle or shaft, a disc or discs or pads of rubber or like elastic
material, or I may arrange a series of springs therein to enable the shaft or axle
to vibrate without effecting the position of the gearing in connection therewith.
In order to admit of the vibration of the axle I provide a number of washers
each having projections or a projection thereon to engage in like recesses or
jaws formed upon the companion washer, the whole forming a clutch which allows
the shaft or axle to be free to move within it while the driving effect is transmitted
from one to the other. The cnd washer I keep in position by means of a screw or
other collar attached to the axle or shaft. By this arrangement of loose and fixed
washers I provide a parallel universal joint or coupling in which the shaft has
freedom of movement while transmitting its driving power.
I employ my improved driving arrangement and my improved elastic hub for
use in connection with motor-cars or for other like purposes.

and for like Purposes.
I, THOMAS WILLIAM NAYLER, of Friars Street, Hereford, in the County of
Hereford, Engineer, do hereby declare the nature of this invention and in what

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention relates to an improved form of driving mechanism used upon
motor cars and for like purposes in which a resilient hub or spring boss is employed
with suitable washers and couplings for allowing vibration of the axle of the
vehicle to be effected without interfering with the driving arrangements of the
mechanism or motor employed in connection with the vehicle.
The invention consists generally in an improved arrangement of elastic hub,
and further in the methods of coupling this clastic hub to the axle and driving
or driven wheel so that rotary motion may be transmitted without in any way
interfering with the complete resilience of the hub in any direction.
The methods of carrying the invention into effect are illustrated in the accom-
panying drawings as follows,--
Figure 1 is a front elevation (one half in section) of the improved hub and
coupling where the motion of a gear wheel is transmitted to the axle or vice versa.
Figure 2 is a front elevation (one half in section) of the improved hub and
coupling where the axles motion is transmitted to the road wheel.
Figures 3 and 4 are respectively front and side view of the improved metallic
clutch or coupling.
In carrying the invention into effect in the manner illustrated in Figure 1
of the drawings the spur or gear wheel A through which the power from the
motor is transmitted is mounted upon the hollow sleeve B and adjusted laterally
therein by the screwed ring C. The road wheel axle D revolves in a shallow
liner E and interposed between this liner and the inner surface of the sleeve B
are arranged a number of rubber discs or pads F, F, though any equivalent device
giving the necessary resilience such as short radially arranged springs may be
employed between the liner and the sleeve, and similarly allow the shaft or
axle to vibrate without affecting the position of the gearing in connection
therewith. Metallic distance rings F, Fi, or other convenient means, may be
employed to hold the discs F F in position laterally.
The clutch for transmitting the rotary motion from the wheel A. to the axle 1)
or vice-versa is constructed as shown in Figures 3 and 4 of a washer G of any suitable
metal or like material with four driving projections integral therewith, and two
of the said projections H, H, are placed on one face of the washer, and the
remaining two H', H', on the opposite face thereof at right angles to the first
two. The washer G is placed in situ (see Figure 1) between a metallic nut and
washer and the projecting boss K of the spur wheel A, and the washer I is
provided with a slot J right across its face of sufficient depth and width to receive
the projections H H of the washer, while similarly the edge of the boss K is
slotted to receive the projections H H¹. The clutch washer is kept in place by
the nut and washer I and the whole arrangement forms a parallel universal joint
or coupling in which the axle 1) has freedom of movement while power is being
transmitted to or from it.
Figure 2 illustrates a modification in which the power is transmitted from the
axle to the road wheel and where a pad or roller is substituted for the discs F F. 4
The axle L revolves in a liner M and placed between this liner L and the hollow
hub N is a continuous roller pad or roller ( with spaces such as P P removed to
allow room for displacement and prevent too great rigidity. This rubber O is
held laterally in position by the screwed adjustment ring Q and the inturned
collar R of the hub. The metallic clutch washer is similar to that hereinbefore 5
described with reference to Figures 3 and 4 and one of these are placed on each
side of the hub, one lying on the right hand side, between the adjusting ring Q
and a collar S formed integral with the axle L; and one on the left hand side
between the inturned collar R of the hub and a metallic washer and nut T.
Similarly, projections H and H fit into corresponding slots J in the metallic 5
surfaces adjacent to them, and the whole arrangement forms a parallel universal

page_text: joint or coupling in which the axle L has freedom of movement, while power is
transmitted to or from it.
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. The improved combined elastic hub and power transmission coupling or
clutch for axles of motors cars, cycles and for like purposes, substantially as
hereinbefore described with reference to Figures 1, 3, and 4 of the accompanying
drawings.
2. The improved combined elastic hub and power transmission coupling or
clutch for axles of motor cars, cycles and like purposes substantially as here-
inbefore described with reference to Figures 2, 3, and 4 of the accompanying
drawings.
3. The improvements in combined elastic hubs and power transmission couplings
for axles of motor cars, cycles and like purposes substantially as hereinbefore
described with reference to the accompanying drawings.
