Improvements in and connected with Motor Driven Vehicles.
I, WILLIAM EDMUND SIMPSON, of 28. Victoria Street, Westminster, in the
County of London, Engineer, do hereby declare the nature of this invention
to be as follows;-
This invention relates to improvements in and connected with motor driven
vehicles.
The main object of the invention is to provide an arrangement whereby the
lever or levers serving to control the direction and speed of motion of the vehicle
may be so interlocked with the steering handle that when the driver releases the
said handle, the lever or levers is or are brought automatically into such a position
that the vehicle is brought to rest, the motor being thrown out of gear or stopped
altogether, and the brakes being also applied. Thus in the event of the driver
being suddenly disabled and failing to properly control the steering handle no
serious consequences will be likely to ensue as might be the case if the vehicle were
to continue to travel uncontrolled.
In carrying out my invention I prefer to provide a single controlling lever
combined with a variable speed and reversing gear of the kind in which a pair of
slotted levers are employed one of which is operated by the motor and serves to
work the other through the medium of an adjustable pin, this latter lever being
connected by a cord or the like with a suitable clutch arrangement. In this kind
of gear the variation in speed is obtained by altering the position of the adjustable
pin, which changes the throw or stroke of the second lever.
Now according to my invention I effect the necessary alteration in the position
of the adjustable pin by means of toggle bars or cams actuated by the aforesaid
controlling lever.
These toggle bars or cams and the reversing gear may be so connected to the
lever that when the lever is moved in one direction or the other, the vehicle is
caused to move in the same direction with a speed corresponding to the degree of
movement of the lever. The lever is normally brought to its intermediate or
central portion by suitable springs, this position being that in which no motion
is imparted to the vehicle.
The brakes are so connected with the lever that they are applied when it is in
this central position.
Obviously such an arrangement of controlling lever may be combined with bevel
gearing or other suitable reversing or variable speed mechanism, instead of with
that above referred to.
According to one arrangement I may provide for retaining the controlling lever
in any desired position, a spring-catch operated by a finger lever and adapted to
engage a suitable notched segment. According to another arrangement I may
employ a smooth segment on which works a double roller clutch, connected with
the lever, this clutch being similar in its action to that described in the specifica-
מ
.

page_text: tion above referred to. The rollers are normally separated by a spring so as to
engage with the segment and are thrown out of action by pusher pieces connected
with spring arms or the like on the handle of the lever."
The interlocking of the levers and steering handle so as to effect the release of
the controlling lever on the release of the steering handle, is brought about by
suitably connecting the said handle with the mechanism by which the lever is
retained in position.
To this end the said steering handle may be connected with the segment of
the retaining mechanism in such a manner that when the said steering handle
is released it moves the segment out of engagement with the aforesaid spring
catch or rollers. The steering handle may be hinged or jointed and provided with
a spring so that it will normally assume a vertical position, from which it must
be raised into a horizontal position for steering, the connections between the steer-
ing handle and segment being so arranged that the segment is out of engagement
as long as the handle is depressed.
If a roller clutch be employed in such a case means are provided to retain the
rollers therein when the segment is removed.
Although I have referred to a lever and steering handle in the preceding
description, yet obviously my invention is equally applicable if hand wheels or
other devices are employed for controlling the motor and steering the vehicle.

Improvements in and connected with Motor Driven Vehicles.
1, WILLIAM EDMUND SIMPSON, of 28. Victorin Street, Westminster, in the
County of London, 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 improvements in and connected with motor driven
vehicles, which improvements are particularly applicable to vehicles provided with
a variable speed gear of the kind described in the Specification of British Patent
No. 27184 of 1896.
The main object of the invention is to provide an arrangement whereby the
lever or levers serving to control the direction and speed of motion of the vehicle
may be so interlocked with the steering handle that when the driver releases the
said handle, the lever or levers are shifted automatically into such a position that
the vehicle is brought to rest, the motor being thrown out of gear. Thus in the
event of the driver being suddenly disabled and failing to properly control the
steering handle no serious consequence will be likely to ensuo as might be the case
if the vehicle were to continue to travel uncontrolled.
In carrying out my invention I prefer to provide a single controlling lever
combined with a variable speed and reversing gear of the kind set forth in the
aforesaid specification, in which a pair of slotted levers are employed one of which
is operated by the motor and serves to work the other through the medium of an
adjustable pin, this latter lever being connected by a cord or the like with a
suitable clutch arrangement. In this kind of gear the variation in speed is
obtained by altering the position of the adjustable pin which changes the throw
or stroke of the second lever."

page_text: Now according to my invention I effect the necessary alteration in the position
of the said adjustable pin by means of toggle bars or cams actuated by the afore-
said controlling lever.
These toggle bars or cams and the reversing gear are so connected to the con-
trolling lever that when the latter is moved in one direction or the other, the vehicle
is caused to move in the same direction with a speed corresponding to the degree of
movement of the lever. The lever is normally brought to its intermediate or
central position by a suitable spring or springs this position being that in which
no motion is imparted to the vehicle.
In order that my invention may be clearly understood and readily carried into
effect I will now proceed to describe the same more fully with reference to the
accompanying drawings in which :-
Figure 1 shows a side elevation of the controlling lever and the mechanism
connecting it with the adjustable pin of the speed controlling levers and with the
levers controlling the reversible clutches.
Figure 2 is a plan of the apparatus shown in Figure 1.
Figure 3 illustrates a roller clutch for retaining the controlling lever in position
on its segment.
Figure 4 is a detail view of part of the roller clutch.
Figures 5 and 6 show the means for connecting the controlling lever segment
with the steering lever.
A is the controlling lever pivoted at a. a is a spring which normally tends to
bring the said lever to its central position. This lever A is retained in any
desired position on a notched rack B by means of the spring catch a which
engages with the notched rack and is operated by the finger lever
According to another arrangement shown in Figure 3, I employ a smooth
segment B and retain the lever A in any required position thereon by means of
the double roller clutch at the rollers of which are normally separated by a spring
so as to engage with the segment, and are thrown out of action, when it is required
to shift the lever A, by means of pusher pieces connected to the spring arms a³,
the rollers then assuming the position shown in Figure 4.
The lever A is connected to the end of a lever c on the transverse shaft D, by
the connecting rod C To the extremities of the shaft D, which is suitably
mounted in fixed bearings, are attached the toggle levers d connecting the said
shaft to the pins d. Each of these pins d is the adjustable pin of a lever speed
gear for operating one of the reversible clutches e, as is fully described in the
Specification of the aforesaid British Patent No. 27184, the said pin being
marked therein. is a rod connecting a lever c¹ on the shaft D to the pivot c³
to which the ends at one extremity of the cranked levers care pivoted. The
forked ends of these levers actuate the sliding drums (marked in the drawings
forming part of the prior Specification No. 27184%) for reversing or throwing out
of gear the reversible clutches e mounted on the driving wheel axle ; and actuated
by the adjustable speed lever gears of which dd are the adjustable pins. The in-
clined slots in the said drums h¹ are so shaped that when the lever A is in the
position shown in Figure 1 the reversible clutches are thrown into gear and the
adjustable sliding pins d are so situated that the motor drives the vehicle at full
speed in one direction; if the lever is thrown right over to the opposite side of its
segment the clutches will be reversed but the pins & will assume the same position,
and the vehicle will be propelled at full speed in the opposite direction; if the
lever A is placed in its central or intermediate position the reversible clutches on
the driving axle will be thrown out of gear, and the pins d, controlling the
adjustable lever speed gear for actuating the said reversible clutches, will be
brought into line with the fixed fulcrums on which the said levers work and the
said gear be thus rendered inoperative. When the lever A is placed in inter-
mediate positions to those above mentioned the vehicle will be driven in either
direction as the case may be and at different rates of speed. G is a cranked lever

page_text: the longer arm of which forms the steering lever, and is pivoted to the steering
axle g at g. This steering arm is normally held in a vertical position by means
of the spring S as shown in Figure 6, and when required for steering is raised
to its horizontal position as shown in Figure 5. The shorter arm of this lever
has a ball at the end thereof which forms a ball and socket joint with a suitable
socket formed at one end of the rod H the other end of which is pivoted at h to
one end of a lever K which is fulcrumed at 2 and has a cam k at the other end
thereof. The segment B is carried by a bar & having a slot b therein in which
are located the two fixed screws or pins, so that the segment is capable of sliding
vertically upon these pins is a pin situated at the free end of the bar band
bearing on the cam &; the steering bar being thus connected with the segment
for retaining the controlling lever in position
When the lever G is raised to the position shown in Figure 5 the cam & acting
upon the pin raises the segment into gear with the lever A. When the driver
releases the steering lever, however, the latter is depressed by the spring S and,
by means of the rod H, moves the cam & so as to allow the rack to fall out of gear
with the lever A. which latter is then brought by its spring a' into its central or
inoperative position and the vehicle is consequently stopped.
Any suitable brake may be connected to the lever A so as to be applied when
said lover is in its central position.
Although I have described my invention as applied to a particular form of speed
gear and reversing mechanism obviously I may adapt the same to other forms of
variable speed and reversing gear without departing from my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare thai what
I claim is:
1. In a motor driven vehicle, interlocking the speed controlling and reversing
mechanism, and the brake, with the steering handle or wheel in such manner that
when the steering handle is released by the driver, the motor is thrown out of gear
with the driving axle of the vehicle and the latter stopped.
2. In a motor driven vehicle, the herein described means for connecting the
steering lever to the controlling lever segment for the purpose specified.
3. In a motor driven vehicle, the roller clutch for retaining the controlling lever
in position on its segment, constructed and operating substantially as described.
4. In a motor driven vehicle, the means whereby the lever or levers serving to
control the direction and speed of motion of the vehicle may be interlocked with
the steering handle, substantially as herein described with reference to the accom-
panying drawings and for the purpose specified.

Improvements in and connected with Internal Combustion Motors.
I, WILLIAM EDMUND SIMPSON, of 28, Victoria Street, Westminster, in the
County of London, Engineer, do hereby declare the nature of this invention
to be as follows;
-
This invention relates to improvements in and connected with internal com-
bustion motors. The main object of the invention is to provide improved means for
cooling the cylinders of internal combustion motors, and for diluting the exhaust
products, so as to diminish the unpleasant odour thereof.
For this purpose I arrange the motor so that the piston on its forward side
acts to pump air through an annular space or casing around the said cylinder, such
air being afterwards caused to commingle with the exhaust.
In carrying out my invention I may provide the motor with a suitable casing
forming a crank chamber, and the cylinder with a suitable casing or jacket
separated therefrom by an annular space which communicates with the aforesaid
crank chamber by a valve controlled passage or passages. The cylinder may be
provided with gills, ribs or other projections extending into the said annular space
and serving to increase the cooling surface.
The arrangement is such that as the piston performs its inward stroke, it draws
air into the crank chamber through a suitable inlet valve, whilst as it performs
its outward stroke, it forces air from the crank chamber through the annular space
around the cylinder, thus cooling the latter.
The commingling of the air, after it has passed through the said annular space,
with the exhaust from the cylinder, may be effected by contracting the outer end
of the cylinder jacket, and arranging the exhaust aperture, which may be of
conical form, centrally in the contracted part so as to obtain an injector-like action
beween the exhaust and the air in the annular space.

ascertained in and by the following statement:-
The invention relates to improvements in and connected with internal com-
bustion motors. The main object of the invention is to provide improved means for
cooling the cylinder of internal combustion motors, and for diluting the exhaust
products, SU to diminish the unpleasant odour thereof. For this
purpose I arrange the motor so that the piston on its forward side ncis
to pump air through an annular space or casing around the said cylinder, such
air being afterwards caused to commingle with the exhaust.
In carrying ont my invention provide the motor with a suitable casing
forming a crank chamber, and the cylinder with a suitable casing or jacket
separated therefrom by an annular space which communicates with the aforesaid
crank chamber by a valve controlled passage or passages. The cylinder may be
provided with gills, ribs or other projections extending into the said annular space
and serving to increase the cooling surface.
In order that my said invention may be clearly understood and readily carried
into effect I will now proceed to describe the same more fully with reference to
the accompanying drawings in which;
Figure is an elevation partly in section of an internal combustion engine, of
the type described in British Patent No. 4924 of 1896, constructed according to my
invention.
Figures 2 and 3 are sectional plan views on the lines and y-y respectively
of Figure 1.
A is the cylinder of an internal combustion engine, provided with ribs a and
surrounded by an external casing a having its upper end contracted to form the
outlui a is the exhaust outlet from the cylinder A arranged centrally within
the outlet a³. Bis the piston working in the cylinder A. b is the piston rod
connecting the piston to the crank pin C. D is the frame or bed supporting the
engine and also forms a sealed casing or crank chamber. d is a suitable air inlet
valve to the chamber D and are outlet valves from the chamber D which com-
municate with the space between the cylinder A and its outer casing a', into
which space the ribs a project. The valves are rubber flap valves held in posi-
tion by the guards ³, and are arranged circularly round the cylinder between the
bolts E which sure the cylinder to the chamber D.
As the piston B performs its inward stroke it draws air through the valve d
into the chamber D, the valves being closed; and as the said piston performs
its outward stroke the valve d is closed and air is forced from the chamber D
through the valves into the annular space between the cylinder A and its
case and thence to the outlet a as shown by the arrows, thus cooling the
cylinder. As this air passes out of the cylinder casing it commingles with the
products of combustion passing from the outlet a³, an ejector like action being set
up tween the exhaust and the said air, and the products of combustion being
thus diluted and to some extent deodorised.
In some cases, as when applying my invention to a motor in which a double-
acting piston is employed, a separate piston may be employed for pumping air
through the casing, (or jacket) and such piston may be double-acting and may
form the cross head of the motor.
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. In internal combustion motors, valves operating in conjunction with the
piston thereof or with an auxiliary piston. for producing a current of atmospheric
air to cool the cylinder and dilute the exhaust products of combustion as they
leave the said cylinder for the purpose specified.
2. In an internal combustion motor a sealed crank chamber fitted with air inlet

page_text: and outlet valves communicating with an annular space between the cylinder and
its casing substantially as described and for the purpose specified.
3. An internal combustion motor constructed and operating substantially as
herein described with reference to the accompanying drawings for the purpose
specified.
