follows:-
--
One object of my invention is to so attach the body or framework of a carriage
to the axle or axles as to relieve the springs of tractive stress.
For this purpose I mount freely on the axle near each wheel a lever or beam
having two equal arins and normally a vertical or approximately vertical attitude
and I so connect the lever arms to the carriage body or frame by links one forward
of the lever the other behind the lever and one higher and the other lower than the
axis of the axle that movement of the axis of the axle in relation to the carriage boly
or frame (as the case may be) can occur only in a straight line, and consequently the
springs will be relieved of any tractive stress. The stresses communicated by the
links will be respectively tensile or compressive according as the carriage is
mechanically propelled or is drawn by locomotive or animal power.
In a mechanically propelled carriage, for the purposes of communicating the
motive power to the wheels and of actuating the hand gea: for pivoting the fore or
locking axle in connexion therewith, so as to afford greater facility for turning
round curves of small radius, I mount two driving wheels freely on a fixed axle
and impart motion to the wheels directly or through any suitable gear by an
arrangement as follows:-On the axle are freely mounted two hollow shafts or
sleeves on each of which is secured a strap pulley tapering or conical in its length.
These pulleys are oppositely arranged and receive motion by two endless straps or
bands from other cone pulleys arranged on the motor shaft or on a counter shaft
driven therefrom. These fast mentioned pulleys have their largest diameters
opposite the smallest diameters of the cone pulleys to which they respectively
impart motion through the straps or bands. Hand gear is provided whereby the straps
or bands can be simultaneously shifted along in the direction of the cone or taper
of the pulleys. When the two straps or bands are running midway of the length
of their respective pulleys, the two pulleys on the axle will rotate at the same rate
and consequently the two driving wheels will be run at one and the same speed,
and according as the straps or bands are shifted from such middle position the
relative rates of rotation of the said two pulleys and the corresponding driving
wheels will be changed. The hand gear for effecting this shifting of the straps or
bands is also connected with that for pivoting the fore or locking axle-and in such
a manner as to cause the relative rotation of the outer and inner driving wheels of
the carriage to exactly conform to the angle of the fore or locking axle due to a
given curved path. If it be desired to communicate a relatively high rotative speed
of the engine or motor to the driving wheels I connect the hollow shafts or sleeves
above referred to with the driving wheels through sun and planet gear of the kind
wherein an eccentric on the quicker running shaft canses a pinion, partly
restrained in its movement by a link, to perform an orbital path around the teeth
of an internally geared spur wheel on the slower running shaft, the axes of the two
shafts being coincident. In lieu of making the pinion and internal wheel with
teeth I may substitute wedge shaped grooves and protuberances or what is known as

page_text: friction gear. By the means described a very considerable ratio of speed in the two
shafts can be obtained with only two wheels.
As will be evident in the construction of carriages some of my improvements may
he used without others, according to requirement,

Improvements in Mechanically Propelled and other Road
Carriages.
1. HENRY STRACEY BARRON late of 32 Gorst Road, Wandsworth Common but
now of Panlinzell, Vardens Road, New Wandsworth, 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:-
My invention has reference to improvements in mechanically propelled and other
rond vehicles as I will now proceed to describe with reference to the accompanying
fom sheets of drawings.
One object of my invention is to so attach the body or framework of a carriage
to the axle or axles as to relieve the springs of tractive stress.
Fig. 1 of the drawings is an elevation, as seen from the inside, of one of the
wheels of a carriage showing one arrangement for carrying out this part of my
invention.
According to this arrangement there is mounted freely on the axle 1 near
ench wheel, a lever or beam 2 having two equal arms and normally a vertical or
approximately vertical attitude as shewn, and the lever arms are connected to the
carriage body or frame by links 3, 4, one forward of the lever 2 and the other
behind it and one higher and the other lower than the axis of the axle 1, 50 that
movement of the axis of the axle in relation to the carriage body or frame (ns
the case may be) can occur only in a vertical straight line, and the springs 5 will
be relieved of any tractive stress. The stresses communicated by the links 3 and 4
will be respectively compressive and tensile if the carriage is mechanically
propelled through the axle 1 say in the direction from right to left (Fig. 1) and
tensile and compressive if it be drawn by locomotive or animal power in the same
direction. The body or frame of the vehicle is not shown but it will be under-
stood that the springs are connected to it by links 5 as usual and that the outer
ends of the links 3, 4 are also connected to it by suitably arranged studs 6, 7.
The dotted lines show the position of the spring and links when the vehicle is
londed.
In a mechanically propelled carriage for the purposes of communicating the
motive power to the wheels and of actuating the hand gear for pivoting the fore
or locking axle in connexion therewith, so as to afford greater facility for turning
round curves of small radius, I adopt the arrangement illustrated in Fig. 2 which
is a plan view of the under portion of a carriage with this part of my
invention
applied to it. In this arrangement two driving wheels 6 and 7 are freely mounted
on a fixed axle 8 and motion is imparted to the wheels directly or through any
suitable gear by an arrangement as follows:-On the axle 8 are freely mounted
two hollow shafts or sleeves 84, 8" on each of which is secured a strap pulley 9 or 10
tapering or conical in its length. These pulleys are oppositely arranged as shewn
and receive motion by two endless straps or bands 1 and 12 from other cone
pulleys 13 and 14 arranged on the motor shaft 15, or on a counter shalt driven

page_text: therefrom. These last mentioned pulleys 13 and 14 have their largest diameters
opposite the smallest diameters of the cone pulleys 9 and 10 to which they
respectively impart motion through the straps or bands. When the two straps or
bands are running midway of the length of their respective pulleys as shewn in
dotted lines the two pulleys 9 and 10 will rotate at the same rate and consequently
the two driving wheels 6 and 7 will be run at one and the same speed, and
according as the straps or bands are shifted from such middle position, the relative
rates of rotation of the said two pulleys and the corresponding driving wheels will
be changed. A vertical hand-operated spindle 16 is fixed to the fore or locking
axle 16 for the purpose of turning it in the usual manner on the circular ring 16
and to pins 16, 16 on either side of centre of the said axle are coupled rods 17, 18
whose other ends are coupled to the two arms 194, 19" of a T-shaped lever mounted
on a stud 20 carried by the framework of the vehicle. The other arm 19° of the
said lever is slotted and fitted with a sliding block 21 journalled on a pin 21°
extending from a bar 22 which is supported by bearings 23 on the under part of
the vehicle frame or body and is adapted by pins 22 to shift the straps or
bands 11 and 12. As will be seen the arrangement is such that when the fore
axle 16 is turned into an angular position as shown movement is communicated by
the rods 17 and 18 to the T lever-which moves the bar 22 endways and causes
the straps or bands 11, 12 to assume a position on their respective cone
pulleys 9, 14 and 10, 13 such as to alter the relative rotation of the driving
wheels 6 and 7 to suit that of the wheels 6 7 on the axle 16 when travelling in a
curved path. If the driving wheels 6 and 7 are to rotate at the same rate as the
pulleys 9 and 10 respectively they are fixed upon the sleeves carrying the respective
pulleys:
In some cases the T lever may be fixed direct to the hand turning spindle which
would then be located at 20 instead of at 16".
If it be desired to communicate a relatively high rotative speed of the engine
or motor to the driving wheels, the arrangement illustrated in side elevation and
horizontal section respectively in Figs. 3 and 4 may be adopted. In this arrange-
ment each hollow shaft or sleeve SA 8B that carries the strap pulley 9 or 10
(Fig. 2) is connected with the corresponding driving wheels 6 or 7 through sun
and planet gear of the kind wherein an eccentric 23 on the quicker running hollow
shaft or sleeve causes a pinion 24, partly restrained in its movement by a link 25
working in a pivoted block 26, to perform an orbital path, around the teeth of an
internally geared spur wheel 27 attached to or forming part of the hub of the
driving wheel. In lieu of making the pinion 24 and wheel 27 with teeth as in
Figs. 3 and 4 may substitute therefor wedge shaped grooves and protuberances
constituting what is known as friction gear, as shown in Fig. 5. Or the pinion 24
may, as shown in Figs. 6 and 7 which are similar views to Figs. 3 and 4 respectively,
be provided with a friction ring 24" of suitable material possessing some elasticity
such as india rubber vulcanite, woodite, or even leather, to work against the inner
periphery of the wheel 27 which may be milled or otherwise roughened to afford a
better grip between it and the friction ring. By the means described, a very
considerable ratio of speed between the sleeves 8 and 8 (Fig. 2) and that of the
driving wheels 6 and 7 can be obtained with only two wheels 24 or 24 and 27
(Figs. 3, 4, 5, 6, 7). The axle 8 (Figs. 4 and 7) does not revolve-but is adapted
to receive the centre bosses of the driving wheels and the sleeves 8A 8º (Fig. 2) to
which the cone pulleys 9-10 are attached.
As will be evident, in the construction of carriages some of my improvements may
be used without others, according to requirement.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Connecting the body or framework of a road vehicle to the axle or axles
thereof by means of levers or beams that are freely mounted on the axle or

page_text: axles near the ends thereof, have equal arms and normally a vertical or approxi
mately vertical attitude, and are each connected to the body or framework of
the vehicle by two links one forward of the lever and the other behind the lever
and one higher and the other lower than the axis of the axle, substantially as
herein before described with reference to and shown in Fig. 1 of the drawings for
the purpose specified.
2. A mechanically propelled rund vehicle having a pivoted fore or locking axle
and a non-pivoted rear axle wherein the driving wheels on the rear axle are driven
by taper or conical band pulleys that are fixed upon hollow shafts or sleeves on the
rear axle and are driven by bands from two similar but oppositely arranged taper
or conical pulleys fixed on the motor shaft, or on a shaft driven therefrom, and the
bands are arranged to be shifted by a band shifting device adapted to be operated
from the hand gear provided for turning the fore or locking carriage, the arrange
ment being such that when the two bands are running midway of the length of
their respective pulleys, the two driving wheels on the rear axle will be driven at
the same speed, and that when the fore or locking axle is turned into an angular
position the bands will be shifted so that the relative rotation of the inner and unter
driving wheels of the vehicle will be caused to approximately conform to the angle
of the fore or locking axle, substantially as described.
3. In a mechanically propelled road vehicle the combination with a pivoted fore
or lacking axle, a non-pivoted rear axle and the wheels thereon, of driving and
regulating mechanism constructed arranged and operating substantially as herein-
before described with reference to and shown in Fig. 2 of the drawings annexed
for the purpose specified.
4. A vehicle provided with driving and regulating mechanism of the kind referred
to in Claims 2 and 3 wherein the hollow shafts or sleeves carrying the band pulleys
on the rear axle are each connected to the corresponding driving wheels on the axle
through sun and planet gear constructed, arranged and operating substantially as
hereinbefore described with reference respectively to and shown in Figs. 3 and 4
in Fig. 5; and in Figs. 6 and 7 of the accompanying drawings.
