COMPLETE SPECIFICATION.
Improvements in Gearing and Breaks for Bicycles and like
Vehicles.
I SAMUEL WARD Red Hill Arnold Nottinghamshire, Hosiery Manager, 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 :-
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a left side view of a bicycle of the usual construction with my
improvements applied thereto.
and
Figure 2 a plan of the same.
Figure 3 a right side view enlarged of a bracket and parts hereafter referred to
Figure 4 a side view of a chain wheel carried by the bracket.
The frame carrying the usual saddle bracket is provided with a bracket 1 on
which two slotted bearings 2 are capable of adjustment horizontally as shown at
Figure 3, between the bearings 2 an axle 3 revolves on a rod 4 the ends of which
are clamped to studs 5 in the bearings 2 by nuts 6, each end of the rod being screw
threaded for that purpose, the upper end of each stud has a screw threaded stem
which passes through the cap of the slotted bearing 2 and is adjusted vertically by
a nut above the cap.
The axle 3 carries a chain wheel at each end, the smaller one 7 shown in side
view at Figure 4 is driven by a chain passed round it and round the usual chain
wheel 8 on the pedal axle, a second chain passes round the larger wheel 9 on the
axle 3 and round a smaller chain wheel 10 on the axle of the rear or driving
wheel.
Intermediately of the chain wheels 7 and 9 the axle 3 carries a break pulley 11
pressed by a piece of leather or other suitable material secured interchangeably to
the underside of a break lever 12 hinged to an arm 13 on the saddle bracket, near
the arm the lever carries a stud hinged to the upper cranked end of a rod 14
provided with a stop washer 15 "shown at Figure 1 the rod after passing through
an arm 16 below which is a second stop washer 17 has its lower end hinged to one
end of a cranked lever 19 carried by an arm secured on the framing the other end
of the lower engages with the lever end of a rod 20 having its upper end hinged to
the back end of a rocking lever 21 carried by a stud secured to the framing, the
front end of the lever is connected to the lower end of a rod 22 having its upper end
hinged to and operated by a lever 23 rocking on a stud secured to the handle bar of
the vehicle. Between the washer 15 and arm 16 the rod 14 carries a spring 18
coiled round it which lifts and holds the break lever 12 clear of the break pulley 11
when the break is not in use, but upon the rider pressing the right end of the
lever 23 up towards the handle of the vehicle the break lever 12 will be forcibly
pressed onto the break pulley and stop the vehicle.
In the drawings two stay rods 24 are shown attached to the bearings of the
driving wheel and to the back ends of the bracket 1. But in new machines the
present backstays will be dispensed with and two stay rods will project at their
lower ends from the bearings of the driving wheel and have their upper ends
attached to the back ends of the bracket 1.
The drawings show a fifteen toothed chain wheel 8 on the pedal axle driving a
wheel 7 with nine teeth on one end of the axle 3, the other end of the axle carrying

page_text: a fifteen toothed chain wheel 9 driving a wheel 10 with eight teeth on the axle of
the rear wheel, but I do not confine myself to such ratio of teeth as the same may
be changed for wheels having a greater or less number of teeth according to the
choice of the rider.
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. In bicycles and like vehicles the construction and employment of a bracket 1
close under the saddle of the vehicle and above the rear wheel, the bracket
carrying an axle 3 with toothed chain wheels 7 and 9. The wheel 7 being driven
by a chain passed round it and the wheel on the pedal axle. The wheel 9 having
a chain passed round it and round a wheel 10 on the axle of the rear driving wheel
substantially as described and illustrated in the drawings annexed.
2. In bicycles and like vehicles the construction and employment of a break
pulley 11 on the axle 3 substantially as described and illustrated in the drawings
annexed.
Dated this Thirty-first day of December 1894.
