Improvements in and connected with Motors for Use in Driving
Vehicles and for other Driving Purposes.
CHARLES ROE and HENRY ROE, Manufacturing Engineers, of 53, Park Road,
Aston, and HORACE KNIGHT, Mechanical Engineer, of New Street, Stoke, Coventry,
all in the County of Warwick, do hereby declare the nature of this invention
to be as follows:-
This invention has for its object the providing of varying speeds especially
applicable for actuating the shafts of motor-cars and the like and also applicable
for the actuating of the shafts of driven machinery of any kind where change
of speed of the driven shaft is required, this invention has also for its object the
providing of means for applying a brake and relieving the driving-belt of driven
machinery.
In carrying out our invention the intermediate shaft of the driven motor-car
or other driven machinery is raised or lowered (preferably radially) from centre
of back axle by means of suitable levers, so that when lowered, the driving belt
will be tightened and drive, and when the shaft is lifted sufficiently high the
drum on the said shaft will come in contact with a brake block or with brake-
blocks and so stop the car driven, or the other machinery driven.
We utilize either the crank-shaft the intermediate shaft-spindle, or the back
axle of a motor-car, and such shafts we drive by means of the pulleys and new
original intervening gear hereinafter described.
When the belt is driving on the forward pulley the shaft rotates in an opposite
direction to that which it would when driven by the reversing pulley.
On the shaft is secured the driving-key, the shaft is free to slide through suitable
bearings from right to left or from left to right, the driving-key slides with the
shaft.
When the driving-key is situated centrally within the bosses of wheels all three
gear-wheels are locked and rotate together with the intermediate shaft at their
normal speed.
By shifting the belt on to the reversing pulley the inner wheel becomes the
driver and through the intermediate pinion gives motion to the outside wheel which
in turn drives the intermediate shaft through the medium of the driving-key but
in an opposite direction to that in which the reversing pulley is being driven by
the belt.
By sliding the intermediate shaft to the extreme right the stop pin engages with
the outside wheel and prevents the same from rotating, simultaneously the driving-
key would shift an equal distance to the right and thereby come in contact with
the internal driving surface of the inner wheel.
As the forward pulley revolved, the pinion would roll round the fixed outside
wheel and impart motion to the inner wheel which takes contact with the driving-
key and thereby causes the intermediate shaft to revolve at a speed governed by
the number of teeth in the gear-wheels.

the driving-key has shifted an equal distance to the left and thereby come in
contact with the internal driving surface of the outer wheel then driving the
intermediate shaft at a speed governed by the number of teeth in the gear wheels.
The pinion is then made hollow and afterwards utilized to contain a suitable
lubricant one end being fitted with a fixed plate and the other end fitted with a
screwed plug so that the plug can be screwed within the hollow pinion and thereby
force out some of the lubricant (through suitable holes) to come in contact with
the teeth of the pinion and be transferred to the whole of the gear teeth to lubricate
the same.

Improvements in and connected with Motors for Use in Driving
Vehicles and for other Driving Purposes.
We, CHARLES ROE and HENRY ROE, Manufacturing Engineers, of 53, Park Road,
Aston, and HORACE KNIGHT, Mechanical Engineer, of New Street, Stoke, Coventry,
all in the County of Warwick, 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 has for its object the providing of varying speeds especially
applicable for actuating the shafts of motor-cars and the like and also applicable
for actuating the shafts of driven machinery of any kind where change of speed
of the driven shaft is required, this invention has also for its object the providing
of means for applying a brake and relieving the driving belt of driven machinery.
We will now proceed to describe with reference to the accompanying drawings
the manner in which our invention is constructed and used.
Figure 1 represents a sectional side elevation of our improved mechanism.
Figure 2 represents a sectional plan of Figure 1.
Figure 3 represents the brake mechanism applied to the brake-drum on the
back axle.
as represented at
In carrying out our invention the intermediate shaft a
Figures 12 and 3 is raised or lowered radially from centre of back axle such
lowering being effected by means of the lever and the lever handle k¹, connected
to the frame o so that when the shaft a is lowered the distance between its centre &
the centre of motor driving pulley is increased, thereby tightening the belt 7 in
drive the pullies b and c.
When the shaft a is lifted sufficiently high the pullies bande will take contact
with the brake blocks as shewn at m and m¹ Figure 1, the block represented in
dotted line m being behind the block represented at m, such contact with the
brake blocks m and m aforesaid prevents the pullies and c from revolving, at
the same time the driving belt would become slack and cease to drive.
The supplementary brake shewn at Figure 3 is operated in the following
manner; the brake lever carrying the brake block m is free to rock on its
fixed bracket and when the shaft a shewn at Figure 3 is lifted by means of the
lever k and lever handle k¹, the frame o shewn at Figure 3 causes the brake lever
to rock on the bracket 2 and thereby moves the brake block m in contact with

page_text: the brake drum thus stopping the motor-car or other driven machinery to which
ou invention is applied.
The pullies and gearing are shewn on the drawings in connection with the
intermediate shaft a but the crank shaft, or back axle can be utilized when
found advantageous.
The shaft a Figures 12 and 3 is driven by means of the pullies
and e and
such pullies b and c are actuated through the driving belt from the motor shaft.
in conjunction with the new intervening gear hereinafter described.
When the belt is driving on the pulley b as shewn at Figure 2 the shaft
rotates in an opposite direction to that which it would when driven by means of
pulley c.
We will now describe the method whereby the shaft and driving key à are
slidden laterally within their bearings.
On the shaft a is secured the driving key as shewn at Figures 1 and 2; the
shaft a is free to slide through suitable bearings and from right to left or
from left to right; the driving key d slides with the shaft a and the sliding of
such shaft a is accomplished by means of the lever q, the connecting rod r, the
lever, the bevil wheel shaft 3 and the lever handle k¹, in combination with the
bevil-gear s and s¹.
The action of the aforesaid levers is as follows, we partly rotate the bevil
wheels s by means of the lever handle k¹, a rotary movement is thereby given to
the bevil wheel s which in turn transmits the motion by means of the shaft
and partly rotates the lever shewn at Figure 2, and by means of the connecting
rod imparts a movement to lever q Figure 2, thereby causing the shaft to slide
through the aforesaid bearings a¹ and a².
When the driving key d is situated centrally within the driving bosses of gear
wheels 9 and e, all the gear wheels are locked and rotate with shaft at their
normal speed.
By sliding the shaft a to the extreme right the stop pin engages with the
wheel 9 at thereby preventing the wheel g from rotating; simultaneously the
driving key d would shift an equal distance to the right and thereby come in
contact with the internal driving surface el of wheel c; as the pulley revolved
the pinions would roll round the fixed wheel g and impart motion to the toothed
wheel e which being in contact with the driving key causes the shaft a to revolve
at a sperd governed by the number of teeth in the gear wheels ef and g.
By sliding the shaft to the extreme left the stop pin h is withdrawn from gl
and the stop pin h¹ engages with the wheel e ate thereby preventing the wheel
from rotating; simultaneously the driving key d has shifted to the left and thereby
come in contact with the internal driving surface e³ of the internal toothl
wheel, as the pulley revolved the pinions of would roll round the fixed wheel e
and impart motion to the toothed wheel g which being in contact with driving
key would cause the shaft a to revolve at a speed governed by the number of
teeth in the gear wheels ef and g.
The springs and Figure 2 are provided and interposed to reduce the speed
of the respective wheels and e before the pins and enter the holes g and g
respectively, thereby preventing any severe shock or shearing action on the stop
pins and h
On shifting the belt by means of the sliding cross-bar and the dependent
fork on the pulley & the wheel e being then securely attached to the same thereby
becomes the driver and the intermediate pinions give motion to the wheel g
which in turn drives the shaft a through the medium of the driving key but
in an opposite direction to that in which pulley is being driven by means of the
belt l.
The pulley is held stationary by means of blocks of rubber, wood or other
suitable material which take contact with such pulley b when the cross-bar is
shifted, such pulley 6 may be provided with projecting strips.

page_text: The lever is provided for the purpose of automatically withdrawing the stop
pin from the wheel e when the belt is shifted on to the reversing pulley c.
The pinion f is made hollow and utilized to contain a suitable lubricant, one
end of such pinion f is fitted with a fixed plate and the other end is fitted with
a screwed plug; between some or all of the teeth of the pinion very small holes
are drilled so that by screwing the plug within the hollow pinion some of the
lubricant is forced out through the very small holes provided between the roots
of the teeth; thereby lubricating the gear wheels.
In some cases we can where desired provide teeth on the faces of either of the
pullies and thereby providing facilities for actuating the same by means of
gear wheels instead of belts.
We can where desired connect the oscillating end of the swinging frame o of
our improved mechanism to the framing of the motor-car or other machine by
means of a suitable supporting spring.
In some cases when the gear is fixed on the back axle instead of the intermediate
shaft a and it is inconvenient to give the required lateral movement to such axle,
the said axle may be a fixture laterally and the gear arranged to move laterally
upon the shaft, thus producing the same effect as when the shaft is moved and
the gear fixed.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is: -
1st. The improvements in mechanism for actuating the shafts of motor-cars
and the like and for actuating the shafts of driven machinery consisting of the
gear wheels, levers and brakes connected together and actuated in the manner
illustrated and described in relation to Figures 12 and 3.
2nd. In improved mechanism for actuating the shafts of motor-cars and other
driven machinery the brake and connections as illustrated at Figure 3 and described
in connection therewith.
3rd. In improved mechanism for actuating the shafts of motor-cars and other
driven machinery the sliding of the shaft a by means of the levers k lever handle ¹
and gear wheels s and s¹ in conjunction with the connecting rod r and lever q.
4th. In improved mechanism for actuating the shafts of motor-cars and other
driven machinery the utilization of stop pins such as h and h¹ so actuated as to
withdraw and release one stop pin and to engage the other stop pin for the purpose
of locking one gear wheel from rotating and liberating the other wheel to thereby
change the speed of the shaft.
5th. In improved mechanism for actuating the shafts of motor-cars and other
driven machinery the utilization of the lever for automatically withdrawing the
stop pin from the wheel e for the purpose of reversing the direction of rotation
of the shaft a in combination with the block u² connected to the sliding cross-bar.
6th. In improved mechanism for actuating the shafts of motor-cars and other
driven machinery the utilization of the hollow pierced pinion f as a receptacle
to contain a lubricant and to thereby lubricate the gear wheels.
