page_text: I JAMES ROBSON of 20 London Street, Fitzroy Square, Middlesex, Builder, do
hereby declare the nature of this invention to be as follows:-
The object of my invention is, to so construct or arrange a tricycle or velocipedé
that by loosening certain parts of the frame the width of the body may be reduced
to enable it, i.e. the machine, being passed through narrow doorways and passages
for convenience of stowage, and be readily made perfect and rigid when required
for riding purposes.
According to my invention, I make the frame of two side bars, connected at
their front ends by sockets and ends of a cross bar or axle, by which the front or
leading wheel if one only be fitted, is held in position. The back end of the side
bars have the axle pins of the rear wheels fixed to theip, said back ends having
socket plates or lugs, to which at one side a transverse bar or bars are affixed by
keys and bolts.
The side frame carries by depending bars, the crank pedals, the rod of which is
swivel jointed near to one end, to enable one part when released from its sidė
frame to be turned upon sideways, the 'fixed part having a disc or other appliance
attached, by which motion can be given to an intermediate gear from which the
driver wheel is operated by an endless chain.
The front or leading wheel, if one only be fitted, is provided with the usual
turning or steering appliances and 'operated by the driver.
The rear transverse frame is preferable of lattice shape and has the parts rigidly
connected by end bars, provided with hinge bolts at one side to the back of one
side frame and fixable to the back of the other side frame by a key to hold that
end and the idle wheel in position, which transverse frame when the key is lifted
can be turned on its hinge bolts 'to allow of one frame being folded towards 'the
other frame and the width of the machine to be thereby reduced.
I have referred to a leading wheel or wheels but by a certain modification in
the arrangement, the steering wheel or wheels may be the trailing wheel or
wheels.

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:-
"
The object of my invention, is to so construct or arrange a tricycle or velocipede
that by loosening certain parts of the frame the width of the body may be reduced
to enable it, i.e.- the machine-being passed through narrow doorways and
passages for convenience of stowage-and be readily made perfect and rigid when
required for riding purposes.
According to my invention, which will be understood by reference to the
annexed drawings in which Figure 1 is a plan of a tricycle, I make the frame of
two side bars A A¹ connected at their front ends by sockets B B and ends of a
cross bar or axle C by which the front or leading wheel D (if one only be fitted) is
held in position. The back ends of the side bars A A¹ have the axle pins of the
rear wheels E E¹ fixed to them, said back ends having socket plates or lugs F F to
which at one side a transverse bar or bars G G are affixed by keys or bolts H, H
(see Figure 2) the other side of the transverse bars G G being held in position by
a spring bolt or key I which may be unbolted when it is desired to fold up the
machine, or both sides of the transverse bars G G may be affixed to the socket
plate or lugs FF said transverse bar being hinged in the centre as shown at
Figures 1, 3 and 5.
The side bars A A¹ carry the crank pedals, the rod J of which is swivel jointed
near to one end K to enable one part when released from its side frame to be
turned up or sideways as shown at Figure 3, the fixed part L having a disc M or
other appliance attached by which, motion can be given by means of a connecting
rod N to an intermediate gear O from which the driver wheel P is operated by an
endless chain Q.
The front or leading wheel D (if one only be fitted) is provided with the usual
turning or steering appliances R.and operated by the driver.
The rear transverse frame G G is preferable of lattice shape as shown at
Figures 2 and 5 and has the parts rigidly connected by end bars S S provided
with hinge bolts H H at one side to the back of one side frame and fixable to the
back of the other side frame by a key I to hold that end and the idle wheel in
position, which transverse frame when the key is lifted can be turned on its hinge
bolts HH to allow of one frame A being folded towards the other frame A¹ and
the width of the machine to be thereby reduced.
Figure 4 is a side elevation and Figure 5 is a view of the rear transverse frame,
formed in two halves and capable of being folded from the centre, the frame when
extended being held rigidly in position by means of a sliding collar T which can

page_text: be moved to fit tightly over the top bar G of one half and a continuation U of the
top bar of the other half of the frame.
I have referred to a leading wheel or wheels but by a certain modification in the
arrangement the steering wheel or wheels may be the trailing wheel or 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
I claim is
1. The improved construction or arrangement of folding tricycle or velocipede
herein before described and substantially as shown in the annexed drawings.
2. So joining the two side frames A A¹ to the front transverse frame Č, that on
a release or folding in of the back transverse frame G the two side frames A A¹
with the drive wheels E E¹ can be brought towards each other as set forth.
