Complete Specification Left, 24th Oct., 1888-Accepted, 7th Dec., 1888
I, DAN ALBONE, of the "Ivel" Cycle Works, Biggleswade, in the County of
Bedford, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to.improvements in the manufacture of convertible velocipedes,
according to which the machine may be a tandem safety bicycle; a safety bicycle; a
front steering tricycle, or a rear driving tandem tricycle, as may be desired; and
when the machine is set as a "safety" to carry two riders, they will both be between
the front and the driving wheels, and both drive on to the same wheel.
In carrying my invention into effect, I make the frame longer than usual, by
inserting a removable piece therein, making the connections by means of knuckle-
joints, or their equivalents. This removable piece carries a second saddle-tube, saddle,
handle-bar, and the necessary additional chain-wheel, chain, and cranks.
To make the machine a tandem safety bicycle, the frame is lengthened by the inser-
tion of the removable piece above mentioned. The chain wheel on the stalk thereof
drives on to the wheel on the back stalk, and the latter on to the rear wheel as
usual.
To convert a tandem safety bicycle constructed according to my invention into a
single safety bicycle, the removable piece is taken out with its attachments and the
frame closed by means of the joint above described.
To convert a tandem safety bicycle constructed according to my invention into a
single tricycle, the removable piece with its adjuncts is taken out the frame shut up
and the rear wheel replaced by an axle and pair of wheels. The axle is strengthened
by the addition of a bridge, and is furnished with a pair of lugs adapted to be connected
to the fork ends of the frame.
To convert a tandem safety bicycle constructed according to my invention into a
rear driving tandem tricycle, I replace the rear wheel of the bicycle in the manner
explained in the last paragraph.
Dated this 24th day of January 1888.

page_text: I, DAN ALBONE, of the "Ivel" Cycle Works, Biggleswade, in the County of Bedford,
Manufacturer, 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 improvements in the manufacture of convertible velocipedes,
according to which the machine may be a tandem safety bicycle; a safety bicycle; a
front steering tricycle; or a rear driving tandem tricycle, as may be desired.
«
When a machine constructed according to my invention is set as a safety" to
carry two riders, they will both be between the front and the driving wheels, and will
both drive onto the same wheel.
In order that my invention, and the means by which the same is to be carried into
practical effect, may be thoroughly understood, I will now describe them in detail,
referring in so doing to the accompanying drawings, which are to be taken as part of
this specification and read therewith.
Figure 1 is a side elevation of a machine fitted with my invention, and put together
as a tandem safety bicycle.
Figure 2 is a side elevation of the same machine converted into a tandem tricycle.
Figure 3 is a rear elevation of the driving wheels, axle, bridge, and connections of
the machine illustrated in Figure 2.
Figure 4 is a plan, to a larger scale, of a knuckle-joint such as is adapted for the
purpose of my invention for use in the machine-backbone.
Referring to Figure 1,
The ordinary backbone is divided into two portions a, a', and has its adjacent ends
finished as parts of knuckle-joints, and thereby adapted to receive a lengthening
tube B, the ends of which are finished to correspond with the respective ends of the
divided backbone.
The lengthening tube is furnished with a stalk C, saddle c, and handle bar d. It
carries at its lower extremity a chain-wheel E, the chain e of which drives onto a
wheelfast on the axis of the back chain-wheel 9.
A tandem safety bicycle constructed as illustrated in Figure 1 and described there-
with is converted into a safety bicycle by freeing both knuckle-joints h and i, taking
out the lengthening tube and its attachments, removing the chain e from the
wheel, bringing the two portions a, a¹ of the back-bone together, and bolting
them up.
A safety or a tandem bicycle is converted, according to my invention, into a front
steering single or tandem tricycle in the following manner.
The back chain j is taken off the chain-wheel k on the axle of the driving wheel;
and the latter, with its chain-wheel, is taken out of the back-fork, and replaced by the
pair of driving wheels illustrated in Figure 3. The axle is strengthened by a
bridge piece m and two braces n, n. From the latter project two studs o, o, adapted

page_text: in respect of position and size to receive the slotted ends of the back-fork, and to
hold it by their nuts o¹, o¹. The chain j is then fixed round the chain-wheel p upon
the axle l.
I am aware that it is not new to convert safety into tandem bicycles by the use of
an auxiliary frame carrying an additional seat, pedal, crank, axis and handle bar, and
I make no general claim, therefore, for the use of such arrangements.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I. declare that what I
claim is :-
1. The combination of divided backbone and lengthening tube, as set forth.
2. The combination of divided backbone, lengthening tube, and knuckle-joint or
equivalent connection, by which the said tube may be inserted in the said backbone
and made a rigid part thereof, as set forth.
.
3. The combination of divided backbone, lengthening tube, additional stalk, saddle,
handle bar, chain-wheel, and chain, as and for the purpose set forth.
4. The method of making safety and tandem bicycles mutually convertible, as the
same is herein before set forth.
5. The method of making single rider and tandem tricycles mutually convertible, as
the same is herein before set forth.
