Improvements in Motor Cycles.
I, MAX E. HERTEL, of 454 Lincoln Ave., in the City of Chicago, State of Illinois,
United States of America, 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 relates to a novel construction in a motocycle or other vehicle, the
object being to provide a device of this kind in which the motor, the gearing.
between the motor and the vehicle, and the brakes, are controlled by a single lever,
and which will be adapted to overcome the variations in resistance in travelling over
any road without varying the speed of the vehicle.
My invention consists in the features of construction and combinations of parts
hereinafter fully described and claimed.
Owing to variations in the character of the road travelled, the load upon the
ariving wheels (or in other words, the resistance offered to their progress) is con-
stantly varying. In order to prevent these variations from producing material
variation in the speed of the vehicle, I so associate a speed governor with the moving
parts of the machine and with the valve for controlling the supply of fuel to the
motor that when the speed decreases the governor will condition the valve to admit
an increased supply of fuel and thereby cause the motor to generate an increased
power for overcoming the increased resistance, and vice versa, and this constitutes
one feature of the present invention. This regulation of the speed of a vehicle by
means of a governor is possible only to the point where the motor reaches its
maximum capacity, and after this point is reached an increase in the resistance will
result either in a decrease in the speed of the vehicle or else in stopping it altogether
according to the amount of the increased resistance.
speed
'
When the motor has reached its maximum capacity and is still unable to over-
come the resistance it becomes necessary to lower the "
"of the gearing
between it and the driving wheels and hence I use variable gearing for this purpose
and the construction of this gearing constitutes another feature of the invention.
By lowering the speed of the gearing some speed in the vehicle is sacrificed, but
this sacrifice enables the motor to continue until the point is reached where the
motor has again reached its maximum capacity and the gearing has been adjusted
to the lowest speed provided for.
In order to prevent sudden variations in the speed of the vehicle from producing
corresponding variations in the speed of the motor and thereby subjecting the
machine to severe shocks and strains, the motor is connected with the driving-
wheels by means of gearing comprising two co-operating members having frictional
engagement with each other and the construction of this gearing constitutes another
feature of the invention. These co-operating friction members permit of a lost
motion between the motor and driving wheels whenever the relations of the load
and power are suddenly varied, either by a variation in the load, due to a variation
in the resistance, or by a variation in the power due to a change in the speed of the
motor.
As a further means for preventing sudden variations in the speed of the vehicle

page_text: from producing corresponding variations in the speed of the motor, I arrange a
fly-wheel on a shaft which derives its motion from the motor through the medium
of speed-multiplying gearing and this constitutes another feature of the invention.
It enables the fly-wheel to be run at a high speed while the motor is running at
a comparatively low speed. When the machine is in operation a certain amount of
energy is stored up in this fly-wheel and when the resistance to the progress of the
vehicle varies this energy is instantly expended in opposition to variation. Very
frequently these variations are of very short duration, as, for example, when they
are caused by the wheels coming in contact with stones or running into little
hollows, and in these cases the energy stored in the fly-wheel and in the moving
vehicle and load will be sufficient to in a great measure prevent them from affecting
the speed of the vehicle and thereby affecting the governor and consequently the
speed of the motor. This insures a steady and uniform as distinguished from an
unsteady and jerky progressive movement of the veliicle.
Another feature of the invention consists in transmitting motion from the crank-
shaft of the motor to a counter-shaft through the medium of speed-multiplying
gearing and transmitting the motion of this counter-shaft directly to the driving
wheels, instead of transmitting motion from the motor directly to the shaft of the
driving wheel..
2
Another feature of the invention consists in incorporating in the gearing, for
transmitting motion from the motor to the driving wheel two co-operating members
which are separable and connecting one of these members with the brake so that
this member and the brake move together..
Another feature of the invention consists in so constructing the movable member
of the gearing so that its component parts will assume a position in which the
lowest speed is transmitted to the driving wheels when starting the vehicle so as to
easily overcome the resistance offered. to such starting and which, afterwards, can
be changed to transmit high-speed by a simple operation of the hand lever.
Another feature of the invention consists in combining with this movable
member of the gearing and the brake a single lever by which both are operated..
Another feature of the invention consists in connecting one of these two separable
members of the gearing and the device for starting the motor with a single operating
lever, the parts being so arranged that when the lever is moved in the direction
necessary for starting the motor it moves the separable member of the gearing
aforesaid away from its co-operating member.
Another feature of the invention consists in providing hand mechanism by which
the motor may be started, (or in. other words; by which. its initial movement may
he produced) by the operator from his position on the seat of the vehicle.
Another feature of the invention consists in providing a single lever for operating
the mechanism for starting the motor, the brake and one of the separable members.
of the gearing.
Another feature of the invention consists in providing the valve gearing with a
part that is connmon to and connected with both the governor and the hand
mechanism for operating the valve so that said part may be moved and the valves
thereby influenced either by the governor or by the hand mechanism.
Another feature of the invention consists in providing the separately swiveled
steering wheel with extension arms and so connecting them by means of a rigid
rod that the wheels are held in proper positions with relation to each other.
Another feature of the invention consists in incorporating a spring in a connec-
tion between arms projecting from the forks of the front wheels and connecting the
opposite ends of this spring with the frame whereby the front wheels are held in
the planes parallel with the rear wheels.
Another feature of my invention consists in so mounting the drive wheels on the
frame and supporting the frame with relation thereto, by means of springs as to
relieve said frame from any shock. or jar to which it would otherwise be subjected
when said drive wheel happened.to encounter a stone or hollow.
Another feature of the invention consists in journaling each of the front wheels

supported by and rigidly connects a pair of links located upon opposite sides of the
wheel, which links in turn are pivoted to the prongs of the fork and extend back-
ward from their pivotal points, the links being held in normal positions by springs
of the particular shape hereinafter, described.
These and other features of the invention are particularly pointed out in the
claims hereinafter, and in order that the invention may be fully understood, I

The present invention is not concerned with the construction of the frame further
than that the frame shall be of such construction that it will afford. suitable means
for the attachment of the parts hereinafter described and. for the accomplishment
of the several objects of the invention, nor is the invention, concerned with the
details in the construction of the motor itself, (i.c., the device in. which is generated
the power for driving the vehicle), a motor of suitable construction being shown at 1
in Figs. 1 and 4: Preferably this motor has two cylinders, a piston fitting in each
cylinder and pitmen 2, both of which are connected at their outer ends, as, shown at

page_text: 3, to the crank 4 of a crank-shaft 5 journaled in bearings 6 supported by the frame.
Motion is transmitted from the crank-shaft 5 to a counter-shaft 7 through the
medium of intermeshing cogs and pinions 8 and 9 carried by the crank-shaft and
counter shaft, respectively. Preferably, in order to keep the weight of the machine
at a minimum, the cogs 8 enter into and form component parts of the crank-shaft
itself. That is to say, the crank-shaft is made up of the two cylindrical portions
that form the journals and fit in the journal boxes 6, the offset or eccentric portion
which forms the wrist or wrists to which the pitmen are connected and a pair of
disks to which these three parts are rigidly secured in the relative positions described,
the peripheries of these disks being provided with teeth so that at one and the
same time they form a part of the crank-shaft and the cog-wheels for transmitting
its motion. The counter-shaft is formed in three sections the central one of which
carries the fly-wheel F and the pinions 9 and it is journaled in bearings fixed to
the frame whereby it is positively held against endwise or lateral displacement,
while the outer sections have their inner ends connected to the central section by
means of universal joints 10 which may be of any desired construction. To each
of the outer sections of the counter-shaft is secured, near its outer extremity, one of
the two separable members of the gearing by which motion is transmitted from the
motor to the driving wheel 11. This member of the gearing is in the form of a
friction-wheel, 12 having in its periphery a V-groove and the member which co-
operates with it takes the form of a ring 13 which is secured to the driving wheel
and is concentric with the axis thereof. Preferably this ring is coated on its ex-
terior with rawhide or
some other material
and
for deadening sound
increasing friction and is secured to the rim of the wheel by means
a screw 15
of arms 14 each of which has a perforation through which
passes loosely and is screwed into the ring, a lock-nut 15° being provided for locking
the screw to the arm when the ring has been brought to a position concentric with
the axis of the wheel, this latter being done by properly manipulating the screws 15.
It has been stated that the friction-wheel 12 has a
V-groove in its periphery,
but the invention is not limited to a groove which is strictly V-shaped.
flaring groove will answer the purpose.

Any
Preferably, this friction wheel is constructed of two disks, one of which, 16, has
a hub 17 which fits loosely upon the counter-shaft 7 so as to be capable of sliding
endwise thereon, said hub being of sufficient length to receive and form a bearing
for a sleeve 18 of the second disk 19.
e
A pin 20 is rigidly secured in the hub 17 the projecting end of which enters a
longitudinal slot 20 in said sleeve 18 and serves to hold said disks 16 and 19 against
relative rotation. Said hub 17 is provided with a slot a which has a portion
extending partially around the same at right angles to the longitudinal axis of said
hub, and a portion c of equal length extending at an angle of about one hundred
and thirty-five degrees to said portion b and in a direction toward said disk 16. Said
sleeve 18 is provided with a similar slot din radial alignment with said slot a in
sai hub 17 and has a portione extending partially around said sleeve in the same
manner as said portion 6 in said slot a, and which is adapted to become flush with
the same to bring said disks 16 and 19 into a given position as hereinafter described.
The portion of said slot d, however, extends at the same angle to the portion
thereof as said portion c to said portion b, but in an opposite direction, that is, at
an angle of about ninety degrees to said portion c. A pin 21 passes through both
of said slots a and d and is rigidly secured in said shaft 7. Said pin 21 is adapted
to engage the walls of said slots a and d to cause said hub 17 and sleeve 18, and
thereby the disks 16 and 19 to turn with said shaft 7, and allow said disks a slight
rotation relative to said shaft. Such slight relative rotation of said disks obviously
causes said pin 21 to pass from the portions 6 and e of said slots a and d into the
portions c and f thereof and, owing to the relative directions in which the latter
extend, will cause said hub 17 to move in one direction thus bringing said disks 16
and 19 together in the position shown in full.lines in Fig. 5. When said disks 16
and 19 are in this position they engage the friction ring 13 adjacent their periphery

or, in other words, at the point where they transmit the highest speed to the drive
A spring 21 is trained around said sleeve 18 and bears at one end against
said disk 19 and at its other end against a plate 22 rigidly secured to the end of the
hub 17, thus serving to hold said disks 16 and 19 normally in the position shown in
full lines in Fig. 5.
The said disks 16 and 19 revolve in the direction indicated by the arrow g- In
starting the vehicle the disks 16 and 19 are brought into engagement with the fric-
tion ring 13 as shown in Fig. 5, while said shaft 7 is revolving. As they come into
contact with said friction ring 13 great resistance is offered to their revolution,
thus causing said shaft 7 to rotate with relation to the same. This causes the
pin 21 to move in said slots a and d in the direction of said arrow g, thus passing
from said portions and f thereof into said portions 6 and e bringing the latter
flush with each other and forcing said disks 16 and 19 apart, against the action of
said spring 21º, as shown in dotted lines in Fig. 5. As said disks are forced apart
they engage said friction ring 13 at points near their centers, thus obviously
applying greater power thereto at the sacrifice of speed. As said shaft 7 revolves
at a high speed it will be obvious that the foregoing operation of the gearing is
almost coincident with its application to the friction ring when the vehicle is at
rest, thus immediately applying its maximum power with its lowest speed
and easily starting the vehicle. After the vehicle is running at the highest
speed of which JS is capable when the above described transmitting
devices are geared to their lowest speed and it is desired to increase the
speed of the vehicle, the speed of the.motor and, consequently, the shaft 7 is momen-
tarily diminished so that the speed of said member 13, which will continue to
revolve for a short space with undiminished speed owing to the impetus of the
vehicle, exceeds the peripheral speed of said member 12 at its point of contact, thus.
causing the latter to turn at a higher speed than said shaft 7, thus causing said
disks to revolve with relation to said shaft in the direction of said arrow g and
causing the pin 21 to again enter the portions c and f of said slots a and d and
bringing said disks into the position shown in full lines in Fig. 5. The spring 21*
obviously aids this latter movement of said disks and serves to hold them in the
latter position. Immediately upon applying said disks to bring them into position
for a high speed, the speed of the motor is increased to the desired point to increase
the speed of the vehicle. Owing to the fact that when the vehicle is in motion,
the speed can be increased without great increase in resistance, the gearing will
not again be lowered, owing to the greater resistance of the spring and the fric-
tional resistance of the portions e and f of the slots a and d, unless resistance to the

is met said gearing will automatically change to decrease the speed and increase the
power in the same manner as in starting the vehicle.
The outer portion of the counter-shaft is journaled in a bearing 23 that is
slidably mounted upon a part 24 of the frame and this permits of the lateral move-
ment of the outer end of the counter-shaft for the purpose of moving the friction
wheel out of contact with the ring 13 when it is desired to prevent the transmission
of any motion from the counter-shaft to the driving wheel. On the other hand,
it permits the friction wheel to be moved toward the ring with sufficient force to
cause the ring to sink deeper into the groove of the wheel.
The journal boxes 23 are connected by links 25 to a pair of arms 26 that are ful-
erumed upon a part.27 of the frame and these arms are rigidly connected by a tie-
rod 28 extending from one of them to the other. This tie-rod is provided with a
tooth 29 which is arranged in operative relation to a dog 30 which is pivoted to a
hand-lever 31 that is fulcrumed to the part 27 of the frame. This dog is under the
influence of a spring 32 which tends to hold it normally in position to engage the
tooth 29, and the dog is connected by a rod 33 to a hand-lever 34 that is fulcrumed
to the hand-lever 31 at 35. When the hand-lever 31 is moved in the direction of
the arrow. Eig. 11. it will engage the tie-rod 28 and move it in the same direction
and thereby move the friction wheel 12 out of engagement with the ring 13. If

page_text: the motion in this direction is continued far enough the brake-shoes 36, which are
fixed to links 25, will be brought into contact with the driving wheels and thus,
it will be seen, by a single continuous movement of the lever 31 the friction wheels
may be moved out of engagement with their co-operating rings, so as to prevent
the transmission of motion from the counter-shaft to the driving wheels, and at the
same time the brakes apply. On the other hand, if the operating lever 31 be
moved in the opposite direction and the dog 30 be allowed to remain in normal
position it will engage the tooth 29 on the cross arm 28 and move the parts in
the opposite direction, thereby moving the brake-shoes out of engagement with the
wheels and at the same time moving the friction wheels into engagement with the.
rings on the driving wheels. If, however, when the lever is moved in this latter
direction the hand-lever 34 be pressed against the lever 31, as indicated by dotted
lines in Fig. 3, the dog 30 will be out of the path of the tooth 29 and hence the
tie-rod 28 and the parts whose movement depend upon its movement will remain at
rest:
:
In order to start a gasoline motor as usually constructed it is necessary to produce
by inanual power an induction stroke and a compression stroke of the piston. In
order to do this a dog 37 is pivoted to the hand-lever 31 and this dog is arranged in
operative relation to a ratchet wheel 37 rigidly mounted on the drive-shaft 5,
its heel 38 being in position to be engaged by a tappet 39 adjustably secured to
the rod 33. This tappet is under the influence of the spring 32 and also of the
Spring 40 so that normally these springs hold the dog out of engagement with the
cog-wheel, but when the lever 34 is pressed to the dotted position already described,
the tappet 39 is elevated and permits the dog to fall into engagement with the
ratchet wheel. While this condition exists, a movement of the lever 31 in the direc-
tion of the arrow in Fig. 11, will cause the dog to move the ratchet wheel 37" in
the direction of the arrow placed upon it, while a movement of the lever 31. in the
opposite direction will cause the dog to drag over the teeth of the ratchet wheel
and engage at a new point on the periphery thereof.. By thus moving the lever
back and forth, the ratchet wheel may be turned far enough to cause the piston to
make the strokes that are necessary in order to inspire a charge and compress it.
When this is done, if the charge is ignited the motor will start, and by releasing
the pressure upon the lever 34 the springs 32 and 40 will again automatically with-
draw the dog 37 from engagement with the cog-wheel 8. When the motor is in
operation and the friction-wheels 12 are out of engagement with the rings 13,
the motor may run at a speed which is controlled by a governor 41 and by the hand
mechanism hereinafter described, to which the action of the governor is subor-
dinated. By properly manipulating the hand mechanism, notwithstanding the
action of the governor, the motor may be set to running at a high speed before it
is geared with the driving wheels and this is an important improvement in a
motocycle since it enables the operator to store up considerable energy in the fly-
wheel before gearing the motor with the driving wheels and thus he is enabled to
overcome resistance that he could not overcome if the gearing between the motor
and driving wheels were not separable, or if the separable members thereof had a
toothed engagement instead of a frictional engagement with each other.
The present invention is not limited to a governor of any particular construction,
nor is it limited to a valve of any particular construction. In the drawing I have
shown a plug valve 42' mounted in a valve casing 43 having a fuel induction port
which is indicated by dotted lines at 44 and an eduction port 45 through which
the charge escapes on its way to the motor cylinders, the casing being also provided
with air induction ports 46. The stem 47 of the valve is pivotally connected to
one end of a lever 48 which carries at an intermediate point a pin 49 occupying a
groove in a sleeve 50 which is capable of moving longitudinally upon a counter
shaft 7 and forms a part of the governor, the other end of said lever being, passed

page_text: at-right angles as shown at 55 and passed out through a slot 56, the extremity of
this bent portion of the rod being pivotally connected to the other arm of the bell-
crank lever 52. The slot 56 permits the rod 54 to move up and down but prevents
it from rotating. The upper end of the rod 54 has a reduced portion 57 forming
a shoulder, and on this reduced portion is loosely mounted, so as to be capable of
turning, a disk 58 to which is permanently secured a sleeve 59 which surrounds the
upper portion of the lever 31 and is provided with a spiral slot GO in which fits a
pin 61 that is permanently fixed to the lever 31. The disk 58 is held in place on
the reduced end 57 of the rod 54 by means of a nut 62, a washer 63 being interposed
between the nut and disk. With this arrangement by turning the sleeve 59, the
spiral slot and pin will cause it to move endwise upon the lever 31 and being con-
nected with the rod 54 so that they are capable of only a rotary movement relatively
to each other, this rod will partake of the endwise movement of the sleeve. This
endwise movement of the rod will cause a movement of the bell-crank lever 52
and this in turn will cause a movement of the lever 48. During this action, the
pin 49 constitutes the fulcrum of the lever 48 and the operator is enabled to move
the valve 42 to any desired position within the range of its possible movement and
thus regulate the supply of fuel to the motor. On the other hand, when the
governor is in action, the bell-crank lever 52 constitutes the fulcrum of the lever 48
so that independently of the movement of the valve by the operator the valve will be
moved by the governor under the conditions that control the actions of the latter.
As shown in Fig. 3ª I prefer to provide the disk 58 with a graduated scale and to
provide the washer 63 with an index by means of which the operator may be guided
in adjusting the valve.
The forks 64 of the front wheels are provided with arms 65 which extend rear-
ward, and to each of these arms is pivotally connected one end of a rigid rod 56,
by which the arms are connected, so that they move together. Theoretically, the
projected axes of all the wheels of a vehicle should extend to a common center or
pivotal axis. When the wheels are all in parallel planes, and the vehicle travelling
in a straight line this pivotal axis is located at an infinite distance, but when
the wheels are moved out of parallel planes in order to turn the vehicle, the pivotal
axis approaches one side or the other, accordingly as the wheels are turned in one
direction or the other, and in making a short turn it is brought quite near.
Where the two steering wheels swivel about a common center (as, for example,
where they are carried by a single axle which swivels about a central pivot or king-
bolt) this condition is maintained by maintaining the steering wheels in parallel
planes, but where they do not swivel about a common center they must not be
maintained in parallel planes, excepting when the vehicle is travelling in a straight
line. The extent of the pivotal movement of the two wheels must differ, the one
nearer the pivotal axis requiring a greater movement than the other. In order to
accomplish this differential movement, the parts are so constructed, proportioned
and arranged that a line drawn through the center about which either of the wheels
swivels and through the point of connection between the arms 65 of said wheel
and the rod 66; will form an angle with the plane of the wheel-instead of being
parallel with it. Between these arms is also a connection comprising a spring 67
and two chains or similar inelastic devices 68 by which the ends of the spring are
connected to the arms, the ends of the spring being also connected by chains or other
inelastic devices 69 to the opposite sides of the frame, whereby the front wheel are
held normally in planes parallel with the rear wheels. The connections between
the spring 67 and the sides of the frame are preferably adjustable, and to this end I
incorporate therein. screws 70 which pass through perforated lugs 71 carried by the
frame, and I arrange on these screws check nuts 72 which engage opposite sides of
the lugs 71.
Pivoted to each of the prongs of each of the forks of the front wheels is a link 73
which extends backward from its pivotal point, the two links upon opposite sides
of the wheel being rigidly connected, so that they are compelled to move together.
Preferably they are connected by means of the axle-74, one end of which is per-

page_text: manently secured to one of the links and the other end of which has a non-
circular portion 75 fitting in a non-circular perforation of the other link, a nut 76
being provided for preventing the withdrawal of the non-circular portion of the
axle from the eye of the link. The links are held in normal positions, with a
yielding pressure, by means of springs 77 located upon opposite sides of the wheel 7
each of which is connected at one end to one prong of the fork and at the other end
to one of the links. I am aware that it is not new, broadly, to journal the front
wheel of a bicycle in links pivoted to the forks, but I believe myself to be the first
to use for this purpose links which extend backward instead of forward from their
pivotal points and which are rigidly connected so that they are compelled to move
together. The advantage of this construction is that it lessens the jar upon the
machine when a stone is encountered.
The drive wheels 11 are mounted upon pins of cranks 78 journaled in the rear-
most cross-tube 79 of the frame of the vehicle, so as to allow said drive wheels to
move with relation to said frame. Pins 80 extend inwardly from said cranks
opposite to said pins upon which the drive wheels 11 are mounted and are provided
with downwardly extending projections 81 provided with openings in their lower
ends through which the upper ends of links 82 pass, by means of which said pins 80
are connected with the springs 83 which support the frame of the vehicle at about
the height of the hubs of said drive wheels. Said springs 83 are secured at their
other ends to downwardly extending lugs 84 on the joints 85 between the parts 24
and 27 of said frame, and are further secured to the parts 24 by means of straps 86,
Docks 87 being interposed between said parts 24 and said springs 83 so as to bring
saiu springs sufficiently low to allow them free movement without coming into con-
tact with any portion of the frame or the parts secured thereto. Obviously, if
said drive wheels 11 come into contact with any obstruction, such as a stone or
hollow, they will pass over the same without subjecting the frame of the vehicle
to any jar, the latter being relieved by the springs 83.
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:-
I. In a motocycle, the combination with a vehicle, and a motor carried thereby,
of gearing for transmitting motion from the motor to the driving wheel, said gearing
including a two-part shaft, two cog-wheels, one carried by each part of said shaft,
a wrist-pin carried by and connecting the cog-wheels eccentrically, a counter-shaft
and pinions carried by the counter-shaft and gearing with the cog-wheels, sub-
stantially as set forth.
2. In a motocycle, the combination with a vehicle and a motor carried thereby,

gearing including separable co-operating members and a shaft carrying one of said
members and having a universal joint, a movable box in which said shaft is
icurnaled, and means for moving the box and thereby separating or bringing to-
