page_text: I, JOHN ASBURY of Cheylesmore, Coventry in the County of Warwick, Machinist
do hereby declare the nature of this invention to be as follows:-
The invention consists in novel means for converting a tricycle into a tandem
of such a character that a lady can with facility ride on the second or back seat.
In carrying out my invention I attach to the main axle of the tricycle a loop or
other suitable frame which extends downwards and rearwards.
The attachment which I prefer to use is that for which I have applied for
Letters Patent in conjunction with Joseph White dated 23 February 1885,
No 2444, which will permit of slight vertical motion of the frame.
At the back of this pendent frame I secure a post, on the top of which the second
seat is secured, and I also provide on the post a suitable attachment for a trailing
or castor wheel, which will allow of lateral motion of the same, and also support
the back of the pendent frame.
In bearings on the pendent frame I mount a crank axle, on which, in addition
to the cranks and pedals, I key a chain wheel to receive a chain from the main
axle, so that the rear rider may assist in driving the vehicle.
From the upper part of the frame will extend to the rear, a pair of arms, which
will support steadying handles, or a steering handle connected to the steering.rod,
which will be prolonged for the purpose.
To one of these arms may also be secured the handle of a suitable brake.
By causing the pendent frame to dip downwards as before mentioned, ample
space will be allowed for a lady to ride on the back seat without inconvenience.

1 JOHN ASBURY of Cheylesmore, Coventry, in the County of Warwick,
Machinist do hereby declare the nature of this invention for "IMPROVEMENTS
IN VELOCIPEDES," and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:―
This invention consists in novel means for converting a Tricycle into a Tandem
of such a character that a lady can with facility ride on the second or back seat.
In the accompanying drawings,
Fig. 1 shows in side elevation my improved Tandem complete.
Fig. 2 shows detached from the Tricycle the parts which carry the second.or
back seat; and
Fig. 3 is a plan view of the same.
The Tricycle, which is a front steerer, is fitted with a pair of joint bearings A A
constructed according to the invention for which I have applied for Letters Patent
in conjunction with Joseph White, under date 23rd February 1885, No 2444.
These joint bearings are made fast to the Tricycle frame B by screwed studs a,
and receive the axle C of the travelling wheels. They form also the connection
between the Tricycle frame B and a detachable frame D (which carries the second
or back seat E), by means of screwed studs a*.-The frame D is formed with a
forked bracket piece d in front, carrying lugs at its extremities, which drop over
the studs a*, and nuts are then applied to the studs to secure the attachment.-
The frame D, which is made of steel tubing, takes a shape somewhat like that of
the letter U, for the purpose of providing a clear through space for the legs of the
seated rider.
The back of this frame forms a socket for the stem of the seat E, and near the
bottom of its front limb is a forked bracket d, forming bearings for the back pedal
axle F. This pedal axle is fitted with a chain wheel for receiving a chain from a
chain wheel on the travelling wheel axle.
dd is a pair of lugs fitted to the back, limb of the frame 1) for receiving the
vertical pivots of a trailing fork G, in which the trailing wheel H is mounted.
The lower pivot of this fork G drops into a fixed centre in the lower lug, and the
upper pivot works in an adjustable centre screwed into the upper lug, and made
fast thereto by a binding nut.
To the extremity of the forward limb of the frame D, a cross piece D¹, for
carrying the pull up handles d³, is secured, and mounted in bearings carried by this
cross piece, is a horizontal rock shaft I, carrying a brake handle i.-This rock shaft
is fitted with a short arm ¹, to which is jointed one end of a brake strap K, laid
around a brake pulley on the axle C of the travelling wheels, and made fast at its
other end to the underside of the forked bracket d.
A stop underlying the cross piece D¹, is fitted to the rock shaft I, and also a
tension springs for maintaining the brake handle in its normal position.
It will be obvious that instead of employing a trailing fork, a castor wheel
arrangement may be adopted for supporting the frame D in position.

page_text: From the foregoing description it will be understood, that ready access to the
back seat, suitable for a lady rider, is provided. The work of the back rider is
transmitted directly from the back pedal axle to the travelling wheel axle, and
the application of the brake, and if desired the steering of the vehicle, may be
effected by the back rider.
+
The use of the joint bearings not only provides for the facile detachment of the
frame D from the Tricycle, but also for the independent rising or falling of the
attached frames B and D.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, declare that what
I claim is
Interposing between the Tricycle frame and the trailing fork or its equivalent,
a frame constructed as above described for carrying the second or back seat, and
affording ready access thereto for lady riders, such frame connecting detachably
with the joint bearings of the Tricycle, and carrying the pedal axle, and also the
pull up and brake handles.
