and attach-ments therefor
Year: 1899

page_text: 1, CHARLES MONTAGUE LINLEY, of 281, Oxford Street, County of London
Engineer, do hereby declare the nature of this invention to be as follows:-
-:
This invention relates to motor cycles and particularly to tricycles and attach-
ments therefor.
In carrying out the invention I employ any usual or convenient motor tricycle
and connect to this a trailing attachment as follows:-
The trailer itself consists of a suitable framework with cranks, foot pedals,
and a road wheel and saddle so that the person sitting upon the trailer can
assist in the propulsion of the whole vehicle if desired. The trailing attach-
ment is connected with the tricycle by a flexible connection which will allow of
the trailer rising or falling, or turning sideways independently of the tricycle
so that suitable accommodation is obtained for inequalities of the road, turning
corners etc. The handles for the rider of the trailer are carried not by the trailer
itself, but by the tricycle, being attached thereto in any convenient manner, and
with any necessary connection.
The trailer may be connected to the cycle by any suitable form of universal
or equivalent joint which will give in all directions excepting in a vertical plane
lying fore and aft of the whole machine.
One way of effecting this flexible connection is to pivot a yoke upon or about
he main driving axle or back part of the frame of the tricycle; this will give
he necessary up and down movement to the trailer. To obtain the movement
ecessary for turning corners the trailer is provided with a steering head con-
ected to or carried by the before-mentioned yoke.
btained by means of a modification of the well known Hooke's joint which will

The same result may be
artly by the trailer, the proportions of the joint and the extent of the wearing
rfaces being adapted to the requirements of the case.
The trailer may be adapted to receive more than one person and more than

page_text: I, CHARLES MONTAGUE LINLEY, of 281, Oxford Street, 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 motor cycles and particularly to tricycles and attach-
ments therefor.
In carrying out the invention I employ any usual or convenient motor tricycle
and connect to this a trailing attachment as follows:-
The trailer itself consists of a suitable framework with cranks, foot pedals,
and a road wheel and saddle so that the person sitting upon the trailer can
assist in the propulsion of the whole vehicle if desired. The trailing attach-
ment is connected with the tricycle by a flexible connection which will allow of
the trailer rising or falling, or turning sideways independently of the tricycle
so that suitable accommodation is obtained for inequalities of the road, turning
corners, etc., the connection is however so made that no oscillatory move-
ment about a longitudinal axis is possible between the cycle and the trailer.
The handles for the rider of the trailer are carried not by the trailer itself, but
by the tricycle, being attached thereto in any convenient manner, and with any
necessary connection.
One way of effecting the flexible connection is to pivot a yoke upon or about
the main driving axle or back part of the frame of the tricycle; this will give
the necessary up and down movement to the trailer. To obtain the movement
necessary for turning corners the trailer is provided with a steering head con-
nected to or carried by the before-mentioned yoke. The same result may be
obtained by means of a modification of the well known Hooke's joint which will
be carried partly by some rigid portion of the framework of the tricycle and
partly by the trailer, the proportions of the joint and the extent of the wearing
surfaces being adapted to the requirements of the case.
The trailer may be adapted to receive more than one person and more than
one may utilize his power for driving purposes if necessary.
This trailer may be provided with a free wheel and any necessary brake, foot-
rests or driving mechanism.
By the term "free wheel is to be understood any arrangement acting to
allow the pedals to remain stationary while the wheel which they normally drive
rotates.
In the accompanying drawings:-
-
Figure is a perspective view showing one construction of trailing attach-
ment according to this invention connected to a motor tricycle, and
Figure 2 is a side elevation of a portion of the machine drawn to a larger
scale.
Like letters indicate like parts throughout the drawings.
With reference first to Figure 1, the frame of the trailing attachment comprises
an approximately vertical tube A forming a steering tube socket and connected
by a horizontal tube B to the lower end of a seat pillar tube C. The upper
end of the steering tube socket A is joined to the same point by a diagonal tube D
and this tube is again connected to the seat pillar tube C by a short cross tube E.
Back forks F and chain stays G are provided and the wheel H of the trailer is
driven from the pedals J by means of a chain wheel K, chain K' and a sprocket
wheel K, the latter being preferably of the free wheel type in order that the

page_text: edals J of the trailer may be stationary except when the rider of the traner is
elping to propel the whole machine.
Within the tube A is another tube A¹ provided at its top end with a steering
head Land handle bar L' and carrying at its lower extremity a yoke M which
by means of clamps M' is attached to the casing N¹ which surrounds the rear
xle of the motor tricycle N. Stays O are placed between the head L and the
ends of the arms of the yoke to give rigidity to them.
Although the head L is termed a "steering head" it will of course be seen
that the rider of the trailer cannot actually turn the tube A¹ and yoke M but
the turning of the trailer relatively to the cycle can nevertheless be facilitated
by the rider.
One of the clamps M¹ is shown in Figure 2 and it will be seen that the
upper jaw is pivotted as at M² and slotted as at M³ to engage with a hinged
bolt which is pivotted on the lower jaw of the clamp. By loosening the nuts
of the bolts M and swinging the jaws M³ back on their pivots the trailer may
be readily detached from the motor cycle. The jaws M are arranged to be an
easy fit round the casing or bar which they grip so that an up and down motion
of the trailer may take place independently of the motor cycle to allow for
inequalities in the road.
It will be seen that the tube A is rigidly attached to the yoke M which is
capable of an oscillatory motion in a vertical plane about the casing of the rear
axle of the cycle as a pivot and the other portion of the trailer can turn about
the tube A¹.
Although the yoke is conveniently clamped to the rear axle of the cycle it may
in some cases be desirable to attach it to the bridge N2 usually provided in
motor cycles. Dotted lines in Figure 1 indicate this method of attachment.
The term "cycle" in this specification is to be understood to cover any
machine with a rigid wheel base, i.e. with three or more road wheels.
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
1 claim is:-
1. A trailing attachment for a motor cycle having driving gear and a
wheel."
free
2. A trailing attachment for a motor cycle having a pivotted yoke such as M
which can be secured substantially as described to the axle or frame of the
cycle.
3. In a trailing attachment for a motor cycle the combination with a pivotted
yoke such as M of a steering head" attached thereto.
4. The complete trailing attachment for a cycle substantially as described and
illustrated in the accompanying drawings.
