page_text: J, THOMAS ROGER FARRELL of 32, Red Lion Street, Clerkenwell, London, E.C.
Bookbinder, do hereby declare the nature of this Invention to be as follows:-
My Invention has for its object to provide rear driving bicycles with a combined
skid brake and supporter whereby the greater part of the rider's weight may be
transferred directly to the ground so as to act most effectively for checking the
progress of the machine even on a steep gradient and enable the machine to be
brought to a dead stop and there remain without the rider alighting.
This improved brake is primarily adapted to be applied by the feet of the rider and
with this object it is constructed of a bifurcated lever jointed to a convenient point
on the main frame, the bifurcated members being adapted to pass below the orbits of
the pedals and towards the rear alongside the driving wheel at either side thereof
preferably as far as to the rear of the point of contact of the driving wheel with the
ground. These rearwardly extending skids would be normally held raised off the
ground by springs or other means attached to the rear fork or other convenient point
and admitting of the skids being depressed and brought into contact with the ground
by the direct pressure of the feet which are removed from the pedals for the purpose
so that the rider by standing thereon may.quickly transfer his whole weight thereto.
Instead of the skid brake being thus operated by the rider's weight the lever may
be continued forward of its fulcrum and connected by suitable means with a brake
lever handle mounted on the handle bar for operation by hand.

I, THOMAS ROGER FARRELL of 32, Red Lion Street, Clerkenwell, E.C. Bookbinder,
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 has for its object to provide rear driving bicycles with a skid brake
such that the whole or the greater part of the rider's weight may be brought to bear
upon it and cause it to be applied directly to the ground in such manner that it will
act most effectively for checking the speed of the machine and enable its progress to
be regulated even down the steepest gradient or to be brought to a dead stop, the

page_text: brake then also acting as a supporter to keep the machine upright without the rider
alighting.
The improved combined skid brake and supporter is illustrated in the accompanying
drawings forming part of this specification, wherein Figure 1 is a side elevation and
Fig. 2 a plan of the brake and of as much of the machine frame as is necessary to
illustrate its application.
The skid brake and supporter consists of a pair of foot plates A supported by the
ends of a bifurcated or shaped lever B B¹ jointed to the main frame or to a suitable
extension thereof the arms of the lever projecting rearwards clear of the pedals and
laterally outwards so as to support the foot plates A in such position to the rear and
outside of the orbits of the pedals as to enable the feet of the rider to be quickly
transferred from the pedals to the footplates when it is required to apply the brake.
The lever arms terminate in downwardly projecting skids or brake shoes C adapted
to bear and slide directly on the ground the skids being normally held raised off the
ground by a spring attached to the lever and to a suitable point of the machine.
In the example illustrated the foot plates A are carried by ring end members a
of the laterally extending cross member B of the 1 shaped lever the forwardly
extending portion of which is constructed preferably of a pair of parallel members B¹
whose forward ends are united to a cross member pivotted in a bracket D carried by a
rigid extension frame formed preferably of a pair of struts D¹ fixed to the bottom
bracket of the main frame, and a tie D² fixed to the bottom tube of the frame, the
object of duplicating the members B¹ of the lever and D₁ of the frame to which it is
pivotted being to afford the necessary stiffness to resist the bending moment
that might arise in consequence of unequal pressure of the two skids upon the ground
or any other cause. The lever B B₁ may however be bifurcated or U shaped and be
pivotted at its cross member in the same way as the 1 shaped lever illustrated. The
skids are depressed as shown in dotted lines in Fig. 1 so as to come into direct
contact with the ground and they are adapted by the rounded form of their faces to
ride over stones or inequalities of the ground and the rider by standing upon the foot
plates A may transfer the whole or any part of his weight to the skids either for the
purpose of checking speed or supporting the machine in the upright position when
stationary.
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. A combined skid brake and supporter. for bicycles, consisting of a pair of skids
carried by a rearwardly and laterally extending lever pivotted to the main frame or
an extension thereof and adapted to be depressed by the direct pressure of the riders
feet thereon substantially as described.
2. The herein described combined skid brake and supporter constructed and applied
substantially as shown and described.
