I HENRY JELLEY of the firm, Jelley Brothers and Company, of 2, North Street,
Wandsworth, Surrey, Tricycle Manufacturers, do hereby declare the nature of my
invention to be as follows:-
:-
The object of this invention is, to arrange telescopic axles for use with Tricycles in
such a manner that either or both main wheels can, after loosening a set screw, be
pushed along a centre pin, towards the chain wheel to reduce the width of the machine,
the reverse operation enabling the wheels to be set further apart for widening it, the
set screw locking the wheels in their respective positions.
For the purpose of my invention I form a broad shoulder or boss at about the centre
of the chain wheel and from the face of the boss I have two pins or rods, one of
which is shorter than the other. Over these pins or rods I arrange tubes which carry
the large wheels, said tubes being slotted to enable them to be moved along when the
set screws are loosened. The screws also pass through sleeves, the inner ends of
which have each a bevil pinion in gear with a bevil wheel on the two faces of the
chain wheel so as to partake of motion therefrom when the chain wheel is turned.
The outer end of the shorter of the two pins or rods abut against a loose fitting
pin or rod in the tube of one wheel and the set screw of this side takes into it.

An Improved Arrangement of Telescopic Axles for Tricycles
(Telescoping from both Sides).
I HENRY JELLEY of the firm Jelley Brothers and Company of 2 North Street,
Wandsworth, Surrey, Tricycle Manufacturers, 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 :-
The object of this invention is to arrange telescopic axles for use with tricycles in
such a manner that either or both main wheels can after loosening a set screw or its
equivalent be pushed along upon a centre pin or rod towards the chain wheel to
reduce the width of the machine, the reverse operation enabling the wheels to be set
further apart for widening it, the set screw, or it may be a key, locking the wheels in
their respective positions.
For the purpose of my invention I form a broad shoulder or boss at about the
centre of the chain wheel and from the faces of the boss I have two pins or rods ;
one of which is shorter than the other. Over these pins or rods I arrange tubes
which carry the large wheels, said tubes being slotted to enable them to be moved
along when the set screws are loosened, the screws also pass through sleeves the inner
ends of which have each a bevil pinion in gear with a bevil wheel on the two faces of
the chain wheel so as to partake of motion therefrom when the chain wheel is turned.
The outer end of the shorter of the two pins or rods abut against a loose fitting
pin or rod in the tube of one wheel and the set screw of this side takes into it.
My invention will be understood by reference to the annexed drawings Figures 1
and 2 section and elevation respectively of a centre driving motion for Tricycles. A
is the chain wheel. B the caulks or sprockets thereon for taking into the links of the
chain which receives its motion from a corresponding wheel connected with the pedal
levers, C is the boss of said chain wheel and D. E. are armis or rods forming part of
same, one, E being shorter than the other. The boss C and the rods D. E. are encased
in sleeves F. G. and the inner ends of these are enlarged and formed with wheel
teeth, H. I. which gear into a pinion J working within the two faces of the chain
wheel A.
'
The two sleeves F. G are carried by bearings K. L. M these having a strap N
attached, to which the T piece P of the backbone and seat carrier are affixed.
The sleeve on the longer rod encloses at its outer end a tube Q, on which one of
the big wheels R of the machine is fitted, the rod D serving as a kind of plug in
said tube for giving stiffness to that side of the machine and when the machine has
to be reduced in width a set screw S with which the sleeve F is provided is loosened,
the tube which is slotted can be pushed along between the sleeve F and the rod D
whereby the wheel R will be brought nearer or closer to the centre of the machine,
such closeness being determined by the length of the slot T as seen at Figures 1
and 2, in one case the wheel R is supposed to be drawn out to its fullest extent and

page_text: the set screw which takes into the rod D fixes said tube at the right hand end of its
slot, while in Figure 2, the wheel R is shown pushed close up to the bearing K the
tube also being pushed along so that the set screw S nips it at the left hand end of
the slot, therefore if the slot be 6 inches long, the wheel R can be set 6 inches closer
to the centre of the machine or at any part thereof by simply loosening the scrow,
pushing the tube in, and tightening up the screw again.
The same operation can be effected with the other big wheel of the machine by
simply loosening the set screw U and pushing the tube V along between the rod É
and sleeve G for the length or any part of the length of its slot. The set screw U
engages in a loose fitting rod W, the end of which abuts against the end of the rod E.
The rod N may be of any desired length and need not necessarily be so long as to
go into that part of the tube V on which the wheel is fitted thus if the slot on this
side be 6 inches long, the wheel can be pushed on to that extent which, with the
reduced width of say 6 inches of the wheel R would make the machine 12 inches
narrower on its wheel base or track.
I have referred to moving both wheels to reduce the width of the machine but this
is only essential for the proper balance of the same the rider being then seated
centrally between the two wheels but if one wheel only be shifted the machine is
capable of being worked, the rider then sitting more on one side than the other and
thereby altering his own propelling action.
Figures 3 and 4 represent a cotter or key S passed through a strap X also through
a slot cut in the sleeve F and tube Q and pressing upon a flat portion of the rod D to
lock the pieces firmly together when the wheel R is shifted along to the desired
position.
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 telescopic axles for tricycles as hereinbefore described and as
shown in the annexed drawings.
2. In connection with telescopic main axles of tricycles so forming the chain wheel
boss that it carries a bevil wheel J gearing into other bevil wheels or pinions H, I, on
sleeves which encircle the boss (and extensions D, E therefrom and encloses within
said sleeves a slotted tube capable of being pushed along on the rods D, E, and fixed
by set screws S, U, or their equivalents such as the key all as, and for the purpose
described.
