IMPROVEMENT IN TRICYCLES & OTHER VELOCIPEDES
Year: 1884

page_text: I THOMAS SHAKESPEAR a director of The Royal Machine Manufacturing Coy La
Herbert Road, Small Heath, Birmingham Manufacturer do hereby declare the
nature of my invention for IMPROVEMENT IN TRICYCLES & OTHER VELOCIPEDES to
be as follows:-
My invention relates to the method of applying the brake to Tricycles & other
similar Machines. I propose to make one handle answer as a resting handle and
also for applying the brake, and the method by which I accomplish this is shown
by the drawing herewith. Fig. 1 represents a side view and Fig. 2 an end view-
on reference to Fig. 1 the drawing shows the drum wheel A to which band brake B
is applied this band I connect with lever C and carry by means of rod D to the
lower end of vertical spindle E, which spindle revolves in bearing F. By giving
the Handle attached to top of spindle E part of a revolution the band B is brought
into contact with drum wheel A and acts as a brake. By applying a spring lever
as shown at G the spindle handle may be fixed when the brake is off, partly on, or
fully on, as desired.
By a re-arrangement of levers, my invention can be applied to Tricycles or
Sociables working with drum wheel in centre of machine.

Company Limited Herbert Road Small Heath Birmingham Manufacturer do
bereby declare the nature of my invention for IMPROVEMENT IN TRICYCLES AND
OTHER VELOCIPEDES, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :—
My invention relates to the method of applying the brake to tricycles and other
similar machines. I propose to make one handle answer as a resting handle, and
also for applying the brake and the method by which I accomplish this is shewn
by the drawings herewith.
Fig. 1. represents a side view and Fig. 2. an end view-the letters of reference 1
indicate corresponding parts in each figure-On reference to Fig. 1 the drawing
shows the drum wheel A to which band brake B is applied-by connection with
lever C.
D is a rod attached to levers C & H. Lever H is fixed to handle shaft E. F is
the bearing in which handle shaft E works and forms part of the left arm of 1
tricycle. G represents a small stop lever attached to handle shaft E by means of
joint I.
At the bottom of lever G is a peg or tooth J which drops into holes or ratchet
teeth cut into bearing F.
K is a spring attached to lever G for the purpose of keeping the peg or tooth J :
in the hole or ratchet teeth in bearing F.
By turning the handle shaft E the band brake B is brought into contact with
the surface of drum wheel A preventing the free movement of machine and the
peg or tooth at bottom of lever G drops into one of the holes or notches in
bearing F and fixes the brake at the point to which it has been turned, thus
avoiding any further muscular strain on the hand of the rider for the purpose of
keeping the brake on. By depressing lever G with the thumb the tooth J is
released from ratchet in bearing F, and by reversing handle shaft E the band
brake B is withdrawn from drum wheel A. altogether, or its pressure regulated to
any degree required.
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
An adjustable band brake applicable to Tricycles and other similar velocipedes
which may be fixed at any desired point so as to sustain the brake pressure
without further assistance from the rider, and by the combination hereinbefore
described I am able to dispense with a seperate handle for the purpose of applying
the brake and thereby simplifying its application by its connection with the
resting handle.
Dated this thirty first day of August 1885.
