PROVISIONAL SPECIFICATION.
Improvements in Cycles.
We, WALTER DARKER-PITT of 24 Stonebridge Park, Willesden, in the County
of Middlesex, Gentleman, and FREDERICK ARTHUR DARLINGTON, A.M.I.C.E.
of Marbury, St. Julians Farm Road, West Norwood in the County of Surrey,
Civil Engineer, do hereby declare the nature of this invention to be as follows:-
This our invention relates to improvements in cycles, and the object of our said
invention is to enable the rider of a bicycle or similar machine, to remain stationary
without dismounting should he require to suddenly arrest his progress, by reason
of a sudden stoppage or slowing of any traffic which he may be following, or from
any other cause.
་
The invention consists of the arrangement and combination of the following parts,
substantially as hereinafter described
A tube of steel or other material is attached to the framing of the cycle by any
suitable joint, extending downwards preferably between the driving and steering
wheels thereof, within the said tube is a plunger which is kept raised by a helical
spring surrounding the same and bearing against a head upon the plunger at one
end, and the closed end of the tube at the other. The rod of the said plunger
extends downwardly from the tube being bifurcated and bent outwards to a suitable
width the outer ends of the said bifurcated portions having mounted thereon castors
or rollers adapted to bear upon the surface of the road when the plunger is depressed..
The depression of the said plunger is effected by the foot of the rider being placed
upon a horizontal bracket which is fixed upon the rod of the plunger at a suitable
point, preferably within the sleeve or tube and extending through a slot in the
same...
Thus it will be seen that the rider may by depressing the device cause the
castors or wheels to bear upon the ground on either side of the machine,. thus
enabling him to maintain his seat.
The bearing of the castors or wheels upon the ground will not impede the
progress of the cycle but will support the machine laterally when going at a slow
pace or when stationary.
The whole device may be easily and quickly detached from the framing of the
machine.
By-means of a set-screw or pin, the plunger may be retained in its extended
position and'the cycle left standing should the rider leave his machine at any time.

page_text: The same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This our invention relates to improvements.in cycles, and the object with which
our invention is devised is to enable the rider of a bicycle or similar machine, to
remain stationary without dismounting, should he require to suddenly arrest his
progress by reason of a sudden stoppage or slowing of any traffic which he may be
following or from any other cause.
The invention consists of the arrangement and combination of the following parts,
substantially as hereinafter described.
In order that our invention may be readily understood, reference is made to the
accompanying drawings in which—
Figure 1, is a side elevation showing the machine with our invention. applied
thereto.
Figure 2, is a cross section of the same, on the line ay Figure 1. And
Figures 3, 4 and 5 are detailed views drawn to an enlarged scale.
Like letters of reference indicate similar parts in all the figures.
A, is a tube of steel or other metal which is. attached by clips or screws to the
frame a of the bicycle. The said tube extends downwardly preferably between the
driving and steering wheels thereof. Within the said tube is a plunger 6 which is
kept raised by helical spring csurrounding the rod B which is screwed or otherwise
fitted into the said plunger, the said spring e bearing against the plunger head bat
one end, and the cap d of the tube A at the other. The rod B extends through
the said cap d and is connected to a horizontal arm e at its lower end, the outer
ends of said arme being bent downwards and carrying thereon castors or rollers
adapted to bear upon the surface of the road when the plunger is depressed. The
depression of the said plunger is effected by means of the rod which carries a
pedal or cross bar i the said rod being mounted in a guide ; on the framing of the
machine and connected at its lower end to a pin or stud upon a loose collar above
the plunger head 6 by means of a depending fork 1. .The said stud k works in a
vertical slot m formed in the tube A.
The arm e in its raised position is preferably in the same vertical plane as the
wheels of the machine to which it is applied and the said arm: is; rotated during its
depression so that when in its lowest position and bearing upon the ground it shall
stand at right angles to the said plane. This rotation is effected by means of a
segmental helical slot n within the tube A in which is engaged a nut or pin upon
the head of the said rod. The depression of the rod operating the rod B thus
causes the pin or stud to traverse the helical slot n thus causing the rod e to. turn a
quarter of a circle, the position of the arm e and the rollers carried thereby is
indica ted by dotted lines in Figures 1 and 2..
The rider brings the device into operation by placing his foot upon the pedal i
thus causing the castors or wheels:g at the extremities of the arm e to bear upon
the ground on either side of the machine, thus enabling him to maintain his seat
while at the same time the contact with the ground will not impede the progress of
the cycle but will support the machine laterally and in a vertical, plane when going
at a slow pace or when stationary.
The whole device may be easily and quickly detached from the framing of the
machine.
•
By means of a set screw or pin p through the guide ; upon the framing of the
machine, the rod h may be retained in its depressed position and the cycle left
standing should the rider leave his machine at any time.
We do not wish to confine ourselves to the exact construction shown as the device
may be operated by means of a hand lever if so desired.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
I..
1. The combination with the framing of a cycle of a.vertical rod carrying at its

page_text: lower end horizontal arms with castors or bearing wheels at their outer ends a
vertical rod carrying a pedal bar for depressing the said wheels, a spring adapted
to normally retain the said wheels in their raised position, and means for partially
rotating the said arms, the whole being constructed, arranged and operating
substantially as described and illustrated.
