Improvements in and applicable to Road Locomotives and Motor
Vehicles.
I EDWARD KENWORTHY DUTTON of Arden Cornwall Road Harrogate in the
County of York Gentleman do hereby declare the nature of this invention to be as
follows:-
My invention relates to vehicles provided with motive mechanism.
In a former invention for which I made application numbered 11587 and dated
May 28th in the present year I used friction wheels and discs to transmit motion to
the driving wheels.
I propose in some cases to use a motor having a vertical shaft carrying a
horizontal disc to act upon the friction wheels. The shaft carrying the said
wheels may be carried by swing arms and be arranged to be moved to withdraw
the wheels from contact with the disc by means of a foot or hand lever or by
suitable means. The said shaft may be connected with the driving wheels or
wheel axles by means of chain or toothed gearing and balance gear. To facilitate
turning a vehicle which may or may not be propelled in accordance with my
inventions I construct the balance gear so that it can be turned into a reversing
motion.
I employ sliding clutches or parts to release the intermediate bevel wheel from
the driving motion and to hold it from being carried around and to connect one of
the other bevels with the driving motion. In one arrangement I mount the two
side bevels upon sleeves on a part which carries the intermediate bevel and adapt
one sleeve and one side bevel to engage with connected clutches which can be
operated by means of a foot lever or by suitable means. When the clutches are
shifted for turning a part is brought into position to prevent the intermediate
bevel from being carried around. The side bevels may drive the two wheels by
means of separate chains.
In a modification the sprocket wheel would be capable of revolving upon a part
carrying the intermediate bevel the connections being effected by means of locking
bolts latches or catches operated by a sliding part.
Instead of thus changing the action of the balance gear I may apply a locking
motion or clutch to one or each driving wheel or axle and connect the same with a
foot lever which would preferably be kept locked by the steering shaft until the
leading wheels would be in position suitable for the vehicle to be turned upon one
locked wheel. The locking might be effected by means of a cam or of cams or of
a recessed collar upon the steering shaft or by other suitable means. I may
arrange for the wheel to be locked by operating upon a hand wheel or handle. In
any case the friction wheels when employed would be prevented from being shifted
to give more than a suitably slow speed when turning.
propose to employ friction gearing to aid in the steering. For this purpose
friction wheels connected in accordance with my invention may be used. I shift
the wheels upon the dise by sliding the friction wheel shaft end wise. A part of
the shaft is screwed and works in a nut which is carried by or connected with a
lever upon the steering shaft or otherwise with the said shaft so that the friction
wheel shaft can be slid endwise in either direction, the shaft immediately working

page_text: back by reason of the screwed part working in the nut. In place of the screw and
nut the friction wheel shaft may be slid by means of a worm wheel or sector fixed
upon or connected with the steering shaft and gearing with a long worm upon the
friction wheel shaft or upon a shaft connected therewith. Reversing clutches
could be used in place of the friction wheels but I prefer the latter. The friction
wheel shaft is connected by spur or chain gearing with a second shaft provided
with a worm which gears with a sector or wheel fixed upon the locking carriage or
part carrying the steering wheels or wheel.
Whenever the friction wheel shaft would be rotated the worm shaft would be
rotated to a corresponding extent so that it would act in unison with the friction wheel
shaft, and put the locking carriage into the required position determined by the
movement of the steering handle. In some cases the friction wheel shaft might
directly turn the worm gearing with the sector and be free to slide within the said
worm.
I prefer to make it impossible to turn the steering shaft to any great extent
without reducing the speed of the vehicle. A cam or excentric may act upon a
lever or part through which the friction wheel shifting notion for varying the speed
would be transmitted.
I propose in some cases to apply an air cylinder or more than one if required to
aid the motor when required and to start the motor if it is of a nature to require
starting.
Compressed air would be stored when the work for the motor would be
light the air cylinder valve or valves being reversible. I enclose the machinery
as much as possible parts of the casing consisting of pervious filtering material.
By the term vehicle I do not exclude such locomotives as traction engines and
road rollers.

Improvements in and applicable to Road Locomotives and Motor
Vehicles.
I EDWARD KENWORTHY DUTTON, of Arden, Cornwall Road, Harrogate, in
the County of York, Gentleman, do hereby declare the nature of my said
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 relates to vehicles provided with motive mechanism and to
locomotives such as traction engines and road-rollers. I employ friction reversing
gearing to aid in the steering of such vehicles and locomotives such gearing being
brought into action by an end-wise sliding shaft which when revolving tends to
work back and to facilitate turning I construct the balance gear so that it can be
turned into a reversing motion.
. In the accompanying drawings which are illustrative of my invention:-
Fig. 1 represents a part of the said sliding shaft and of the parts for effecting
the sliding of the same and
Fig. 2 shows another method of effecting the sliding of such shaft.
In Fig. 1, a is a shaft which is fitted to revolve in suitable bearings and also to
move endwise in either direction. A portion of this shaft is cut with a screw
thread and a nut b engages with such thread. This nut would be connected with
the steering shaft of the vehicle in any suitable manner so that the nut could be
acted upon to slide the shaft end wise in either direction.

page_text: In the example, side links ce are supposed to connect the nut with a lever upon
the steering shaft of the vehicle but as the parts for connecting the nut and, the
steering shaft may be greatly varied they are not shown in the drawings.
In Fig. 2 the end-wise movement of the shaft is effected by means of a worm
wheel or sector d which engages with a long worm or screw e upon the shaft a..
The worm wheel may be fixed upon the steering shaft of the vehicle or be
connected with it by suitable means.
When the worm wheel is turned in either direction it causes an end-wise
movement of the shaft a. The said shaft or a shaft coupled to the same is
supposed to extend through the parts in Fig. 3 wherein the said shaft is seen
passing through two friction wheels ff1 which are mounted to revolve loosely
upon the shaft and are connected by bevel wheels g g 1. The intermediate
wheel g 1 is carried by a block / which is fast to the shaft.
The two friction wheels are in contact with a disc i which receives a rapid
revolving motion-say in the direction indicated by the arrow-from the motor of
the vehicle whereby the two friction wheels are revolved in contrary directions.
So long as the two wheels are equidistant from the disc centre the shaft a will
remain at rest. Supposing that the said shaft is moved end-wise in the direction
indicated in Fig. 1 so as to bring the wheel nearer to and the wheel f1 further
from the disc centre the shaft will be revolved in the indicated direction. It will
be seen that by reason of the screw working in the nut the shaft will slide back so
that the two friction wheels will be shifted back to their normal positions and the
revolving movement of the shaft will cease. By sliding the shaft in the contrary
direction the shaft will be revolved in the contrary direction.
The result of this action of the parts is that when the driver of the vehicle
moves his steering lever the friction gearing turns the shaft in the direction and to
the extent determined by the movement of the lever and then.ceases until the
driver moves the lever back or makes a further movement of the lever. The
shaft a may be caused to turn a worm gearing with a worm wheel upon the locking
carriage of the vehicle or may be.connected with any suitable parts adapted to put
the vehicle wheels in the.required positions. It will be understood that if the last
mained worm is upon the shaft a the shaft,must be free to slide in the worm without
moving it end-wise,
A bar el or other means is or are employed to keep the.nut from revolving with
the shaft.
:
Fig. 4, shows an arrangement.adapted for cases wherein the shaft a could not
extend across the axis of the shaft actuating the reversing motion. A bevel
wheel is fixed upon a shaft k.which revolves when the vehicle is in motion. With
the wheel either of two friction wheels 11 may be caused to engage by sliding the
frame m in one direction or the other. This sliding movement is derived from the
shaft a which is mounted in the frame and is connected with the friction wheels' by
means of spur gearing. It will be seen that the revolution of the shaft a will only
continue so long as the shaft is moved end-wise in either direction.
In Fig. 5, the shaft a carries a pair of friction cones n n which are adapted to
engage with hollow cones which are formed in .bevel wheels o o and are .connected
by an intermediate bevel wheel p the parts constituting a friction clutch reversing
motion. The action is the same as that of Fig. 4, either clutch.being put in action
by sliding the shaft a and disengaging itself immediately the movement of the
steering lever ceases.
Such a motion is suitable for heavy vehicles or for cases wherein the driving
shaft actuated by the motor or vehicle axle does not revolve rapidly.
The remaining figs. illustrate.the.improvements in the balance gear. In Figa. 6
and 7.QQ are the inner ends of the driving wheel axles of a vehicle upon which
are fixed the two bevel wheels R R1 of the balance,gear. In the ordinary gear
the sprocket wheel S would be fixed or formed upon the part carrying the inter-
mediate bevel T bat in the example the sprocket wheel is fitted to revolve upon a
wheel U in which the intermediate T is mounted and to engage with and be

page_text: disengaged from the wheel U as may be desired. The wheel U is formed with a
druni u upon which a brake can be caused to act. In the sprocket ring are mounted
short spindles V which are formed with reverse pawls V1 V 2. On the wheel U
are formed teeth with which the pawl V 1 can engage and upon a rim upon the
bevel R 1 are formed teeth with which the pawl V 2 can engage.
The latter pawl is connected by a link V 3 with a sleeve W which can be slid
upon the axle by means of a lever or by suitable means. When the said sleeve is
near to the bevel R1 the pawl V 2 is out of gear with the said bevel and the
pawl V 1 is in gear with the wheel U as in the drawing the balance gear then acting
in the ordinary manner.
When the sleeve is moved away from the beve! the pawl V 2 is brought into
gear and the pawl V 1 out of gear the wheel U being held by means of the brake
or by other suitable means. The sprocket wheel will then drive the wheel R 1
which acting through the intermediate bevel will revolve the wheel R in the
reverse direction.
The motion illustrated by Fig. 8 is adapted for cases wherein the motion is
transmitted to the vehicle axle by means of an intermediate shaft. In the fig. a
part of such a shaft is represented by X being hollow in the example. Upon this
shaft two bevel wheels are mounted to revolve loosely and are connected by an
intermediate bevel as in ordinary balance gear. The intermediate Y is carried by
a brake drum partly represented by Z which is also loose upon the shaft. The
hub of the brake drum and the eye of the bevel A are both slotted to suit a key B
which is fixed to a rod C which can be operated by the driver.
The ends of the key extend through slots in the shaft so as to engage with the
slots in the bevel A or the hub Z as may be required. In the fig. the key is in
driving gear with the bevel whecl. If the brake be applied to keep the part Z
from revolving the gear will act as a reversing motion the wheels A and D
revolving in opposite directions but if the key be shifted out of the wheel A into
the boss of Z then the two wheels A and D will revolve in the same direction
as the shaft. Each bevel carries a sprocket wheel E and chains connect these with
the two driving wheels or axles of the vehicle. The steering wheels should be
capable of being put into positions which will allow the vehicle to turn around
when the driving wheels revolve in reverse directions.
The shaft X may be solid and the changes be effected by means of clutches
sliding on the shaft and engaging one with one of the bevels and the other with a
sleeve attached to the part 2 and extending through the other bevel, or through
the same bevel.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination of parts substantially as and for the purpose, set forth and
indicated with reference to Figs. 1 and 3 of the accompanying drawings.
2. As means for communicating motion from the motor or a revolving shaft of
a vehicle or locomotive to the parts which turn the locking carriage or angle the
steering wheel or wheels; a shaft mounted to slide endwise and connected with
friction reversing gear which is put in action by sliding the shaft such sliding
movement being imparted through a nut or wormwheel acting upon a screw thread
upon the shaft so that the revolution of the shaft tends to put the reversing motion
out of driving action substantially as set forth.
3. The combinations of parts substantially as and for the purpose set forth with
reference to Figs. 6, 7, and 8 of the drawings hereto.
4. The balance gear adapted to have parts arranged to engage and be disengaged
by means of catches pawls keys or clutches substantially as and for the purpose
set forth and indicated.
5. The method of and means for converting the balance gear through which

page_text: motion is transmitted to the driving wheels of vehicles of the class herein referred.
to into reversing motions substantially as and for the purpose set forth and
indicated.
