IMPROVEMENT IN HUMBER PATTERN TRICYCLES
Year: 1885

I ALFRED TOM SHELLARD Engineer & Machinist 3 Old King St Bristol do
hereby declare the nature of my invention for IMPROVEMENT IN HUMBER PATTERN
TRICYCLES as above to be as follows:-
The improvement consiste in an arrangement for giving rider power over wheels
in steering also for placing the backbone & back wheel under his control as well.
Arrangement consists of 3 cogs one attached to end of a vertical steering handle
an intermediate cog & a small cog attached to neck as in drawing or attached to
bottom centre similar to the bottom of steering handle. The back-bone is fixed to
head or tubing that constitutes the head. The neck instead of being in back-bone
is in front bone. I claim the absolute right of having invented an arrangement
that gives the rider control over back-bone & back wheel without its being a rear
steerer I also claim the fixing of backbone to head instead of working in it which
is entirely new in these machines. Also the right of placing neck in front bone
instead of in back bone The arrangement may be either worked with two three
or four cogs or with quadrant & wheel or with slot link & wheels or any other
mechanical contrivance to effect the purpose without altering the principle.
Dated this 8th day of September 1885.

page_text: and for Placing the Backbone Under Control.
I ALFRED TOM SHELLARD, of 3 Old King Street, Bristol, Engineer, 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:-
This Invention consists of improvements in the steering apparatus of tricycles
constructed on the "Humber" pattern, for the purpose of placing the wheels and
back bone under more perfect control.
With this object, the handle bar is not attached to a continuation of the front
bone of the machine, but is mounted on a separate stem or rod placed vertically
between the saddle and the front bone upon which it acts through the medium of
connecting links or toothed wheels.
Both methods are illustrated in the accompanying sheet of Drawings, Figure 1
of which represents a side elevation of the apparatus and Figure 2 a plan view
thereof.
A represents the back bone of the machine and B the front bone thereof which
is arranged so as to turn freely in the hollow tube C.
The handle bar D is attached to the top of a rod or stem E on the bottom of
which is a cross bar F, a similar cross bar G being attached to the front bone B.
The cross bars F and G are connected by links H so that any motion of the
handle bar is transmitted to the front bone which carries the wheel bearings J.
In Figure 3 I have shewn elevation of portion of a machine in which the front
bone is pivotted upon a spindle K, the bearings of which are attached to the
tube C. On the bottom of the handle bar is a toothed wheel L which through
the medium of the carrier wheel M acts on a toothed wheel or segment N connected.
with the front bone.
.. Having now particularly described and ascertained the nature of my said
Invention and the manner in which the same is to be performed, I declare that
what I claim, is:-
1. Fixing the back bone to the head of the machine instead of having it to
work therein and forming the joint or neck in the front bone.
2. The arrangement of steering mechanism shewn and described in reference to
Figures 1 and 2 of the accompanying drawings.
3. The arrangement of steering mechanism shewn and described in reference to
Figure 3 of the accompanying drawings.
Dated the 24th day of November 1885.
