We, ALEXANDER CRAIG, Chief Engineer, and WALTER PHILLIPS, General
Manager, both of Messrs. Humber & Company Limited, of Coventry, in the County
of Warwick, do hereby declare the nature of this invention to be as follows:-
This invention relates to motor vehicles, one of its objects being the attachment
of the motor to the vehicle, say a tandem tricycle with a pair of leading wheels
and a single driving wheel for instance, by tubes clipped to the seat pin and rear
axle in such a manner as to make it easily detachable. In one construction accord-
ing to this invention the tubes of the motor frame are attached to the motor itself
by the bolts which hold the crank case together, upper bolts being employed as
hinge-pins for two of the motor frame members which extend to the rear axle of
the tricycle, and lower bolts serving to engage forks on the ends of other tubes
which also extend to the rear axle and are provided with chain adjusting devices,
thus forming an adjustment for the motor driving chain which may be tightened
or slackened in a manner well understood, the motor in this adjustment turning
slightly about the hinge-pins constituted as aforesaid. The tubular connections
between the carburettor and lamp tank, carried on convenient parts of the frame,
are preferably flexible. The motor frame tubes extending from the hinge-pins to
the back axle are in compression and from the same hinge-pins or points adjacent
tension members extend to the seat pin. These tension members may as an
alternative extend from the seat pin to the forks on the ends of the lower tubes
before referred to, crossing the compression members, and if desired being joined
thereto.
In order that the weight of the motor may not unduly affect the back wheel of
the tricycle, the bottom tubes may be hinged to turn freely about the ends of the
rear axle, and a tension spring can be inserted in the tension member or members,
thus carrying the motor on a kind of spring frame.

Although this invention is herein before described in its application to a tandem
tricycle of a particular type by way of example, it is to be clearly understood
that it is applicable in like manner by slightly modifying the arrangements of
the parts to other types of motor vehicle, and such modification is regarded as
being within the scope of the present invention.

page_text: We, ALEXANDER CRAIG, Chief Engineer, and WALTER PHILLIPS, General
Manager, both of Messrs. Humber and Company Limited, of Coventry, 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 relates to motor vehicles, one of its objects being the attachment
of the motor to the vehicle, say a tandem tricycle with a pair of leading wheeis
and a single driving wheel for instance, by tubes clipped to the seat pin and rear
axle in such a manner as to make it easily detachable. In one construction accord-
ing to this invention the tubes of the motor frame are attached to the motor itself
by the bolts which hold the crank case together, upper bolts being employed as
hinge-pins for two of the motor frame members which extend to the rear axle of
the tricycle, and lower bolts serving to engage forks on the ends of other tubes
which also extend to the rear axle and are provided with chain adjusting devices,
thus forming an adjustment for the motor driving chain which may be tightened
or slackened in a manner well understood, the motor in this adjustment turning
sligatly about une hinge-pins constituted as aforesaid. The tubular connections
between the carburettor and lamp tank, carried on convenient parts of the frame,
are preferably flexible. The motor frame tubes extending from the hinge-pins to
the back axle are in compression and from the same hinge-pins or points adjacent
tension members extend to the seat pin. These tension members may as an
alternative extend from the seat pin to the forks on the ends of the lower tubes
before referred to, crossing the compression members, and if desired being joined
thereto.
In order that the weight of the motor may not unduly affect the back wheel of
the tricycle, the bottom tubes may be hinged to turn freely about the ends of the
rear axle, and a tension spring can be inserted in the tension member or members,
thus carrying the motor on a kind of spring frame.
In the accompanying drawings,
Figure 1 is a perspective view of a tandem tricycle with a motor attached,
according to one method of carrying out this invention; and
Figure 2 is a perspective view of the rear portion of a bicycle or tricycle illus-
trating a modified method of attaching a motor to a vehicle.
Like letters indicate like parts throughout the drawings.
i.
Figure 1 illustrates a tricycle A of the well known Olympia" type to which
it is desired to attach a motor B. The type of motor shown is of the well known
De Dicn construction in which the several parts of the crank chamber B¹ are
bolted together by the bolts B2, and in attaching the motor B.to the tricvele A
the bolts B2 are used for connecting the motor to its supports. Two forked or
duplicated members CCI are secured to the motor B by the bolts B2 at the upper
and lower portions of the crank chamber B respectively. The ends of the mem-
hers CC remote from the motor B are secured at A to the axle of the driving wheel
A of the tricycle. A third forked or duplicated member C2 is secured at one end to
the bolt B2 which carries one end of the member C, the other end of the mem-
ber being secured to the seat pillar of the tricycle at A³. The members C and C

page_text: are free to pivot about the bolt B by which they are secured to the motor B and
the member C is provided on either side of the motor B with an adjustment
device C³. This adjustment device C is of any of the well known constructions
used in cycles for the purpose of adjusting the driving chain.
On the motor shaft B³ is mounted a sprocket B which drives a chain wheel D
(mounted on the driving wheel A' of the tricycle) by means of a chain D'.
If preferred the member C in place of being secured to the motor B at the
point where the member C is secured may be carried across the member C and
secured to the motor B at that point where the member C is attached. This
alternative position is illustrated by chain lines in the drawing. The mem-
bers CC may be either brazed into a common lug at A2 or may be separately
connected to the axle of the driving wheel A¹.
The operation of this mechanism is obvious;-
The member is in tension, while the members C C are in compression. The
chain is adjusted when desired by means of suitable adjustment devices C³
(one only being shown in the drawings) which causes the motor B to swing upon
the bolt B by which it is connected to the members CC2 thus increasing or
decreasing the distance between the sprocket B and chain wheel D. In order that
this movement may be allowed to the motor B the pipe which supplies the explosive
charge to the motor may be made wholly or in part of flexible tubing and any
operating rods or other connections arranged between the motor and tricycle must
also be provided with suitable links or flexible portions.
It will be seen that by disconnecting the member Cat A3 and the members C
at A² from the tricycle A the motor is readily removed and the tricycle left intact.
The chain wheel D may also be arranged to be easily removed from the wheel A'
if necessary by taking the latter out of its frame."
In the mechanism illustrated in Figure 2, the members C C₁ are made to pivot
about the axle of the driving wheel A and a spiral spring C is interposed between
the member C and its connection to the seat pillar of the tricycle at A3.
The member in Figure 2 may also be arranged in the position indicated by
chain lines in Figure 1, and when the member is thus arranged whether according
to Figure 1 or Figure 2, it may if desired be secured to the member C at that
point where the two members will intersect.
The object of this device is to lessen the strain upon the wheel of the motor A'
when the latter for instance is passing over uneven ground, by causing the motor
to swing about the point A2 while the spring C+ extends or contracts.
It will be understood that in the place of chain and chain wheel driving gear
being used between the motor B and the driving wheel A "Acatene" or any
other convenient form of driving gear may be utilised, the particular form of
gear forming no part of this invention. Also the wheel A¹ may if desired be
made removable from the tricycle with the motor, or the motor only may be
removable and attached when required to any ordinary cycle wheel. Further
any convenient form of motor may be used and if such motor has not convenient
bolts such as B to which the members C C C may be connected these members
may be attached by means of any convenient studs or bolts. The members CC'
need not necessarily be attached to the axle of the wheel A' at A2 but may if
preferred be secured to a portion of the cycle or vehicle frame.
Although this invention is hereinbefore described in its application to a tandem
tricycle of a particular type by way of example, it is to be clearly understood that
it is applicable in like manner by slightly modifying the arrangements of the
parts to other types of motor vehicle. If preferred the motor might
be attached to the front or steering wheel of a cycle or other vehicle.
It can easily be seen that either of the arrangements described with reference to
Figures 1 and 2 might with very slight modification be adapted for attachment
to the steering fork of a bicycle for instance, instead of to the rear fork of a
tricycle as shown and any such modification is regarded within the scope of the
present invention.
