cturer, opencer I lace Dlackneat nent, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in tricycles in which two riders sit side by
side. Machines of the type have hitherto been made with the two driving wheels
outside the two riders, and are very wide and cumbersome.
The novelty of the invention, is to make the machine very narrow, this is done by
placing the two riders over each of the driving wheels instead of between them; and
the arrangement of framing of the machine as hereafter described.
According to the invention I place a saddle or seat over each driving wheel. The
driving is transmitted through a balanced geared axle, by two chain wheels and
endless chain or bands; from two cranked axles placed underneath the seats or
saddles.
In front of the seat or saddles are two Tee-handles, one handle is fixed to the frame,
and the other handle is connected to the steering wheel fork, by means of a steering
rod, chain or band, or any other suitable arrangement.
The frame of the machine is constructed of tube or any other suitable material, and
is of an oblong form, placed between the two driving wheels. The front part of the
frame, carries at each end, the supports for the Tee-handles and the centre carries the
steering wheel fork socket.
The back part of the frame carries the bearings, in which the balance gear axle
works near the centre of each side of the frame are two brackets thrown outwards
to the centres of the two driving wheels; through these two brackets are carried two
vertical tubes, the lower extremity carries the crank axles, and the upper part carries
the seats or saddles, which are adjustable to suit the height of the riders.
I am aware that machines have been made, with two riders sitting over the driving
wheels; but such machines have been made without balance gear each rider driving
his wheel independly of the other.

I WILLIAM BUTCHER Cycle Manufacturer of Spencer Place Blackheath in the
County of Kent 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 improvements in Tricycles in which two riders sit side by
side. In carrying out the invention the saddles or seats I (Figs. 1& 2) are placed
above the centre of the two driving wheels, and are mounted on the curved seat
supports 1 & 2 carrying at their lower extremities the pedal and crank shaft
brackets 3; from which motion is transmitted to the axle 4 provided with balance
gear 4 by means of the two chains and chain wheels 61 and 6. The axle revolves
in the bearings 71 and 7" and is carried by the bridge tube 8 from which two
stay tubes 9 connect the curved seat supports 2 and 2¹¹.
From the seat supports the frame is extended to the cross bar 10 which is provided
with a steering socket 11 carrying the steering wheel in the fork 12. In front of tho
saddles or seats 1' and 11 are two adjustable Tee handles 13 and 1311 the handle
socket 14 is provided with a small lever 15 connected by a steering rod 16 to the
steering fork lever 17 so the handles 131 is used for steering the machine, and the
handle 18 is fixed.
In the centre of the balance geared axle is a brake drum 17 which is actuated by a
brake lever and strap not shewn on drawing. The machine can be considerably
reduced in width by making the two Tee bandles 13 and 13" to turn lengthways of
the machine and disconnecting the two outside pedals.
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 as follows
Claim I. In Tricycles where the riders sit side by side, the placing of a seat or
saddle over each driving wheel transmitting the power of the two riders by means of
gearing and a balance geared axle to the driving wheels as shewn in Figs. 1 and 2.
II. The arrangement of Frameing, Steering, and the manner in which the machine
can be reduced in width as applied to Tricycles where two riders sit side by side, as
substantially described and shewn in Figs. 1 and 2.
