IMPROVEMENTS IN METALLIC WHEELS FOR COMMON ROAD CARRIAGES
Year: 1884

page_text: I THOMAS JEFFERIES of 142 Bradford Street Birmingham County of Warwick
Japanner do hereby declare the nature of my invention for IMPROVEMENTS IN
METALLIC WHEELS FOR COMMON ROAD CARRIAGES to be as follows:-
My invention consists in the application & use of metallic tubeing for the
periphery of wheels in general & for the casting together of the different parts in
or at the centre of the same, by the method known as stock casting. In the
construction of these wheels, after the tube is formed into a circle, I then bring the
faces of the two opposite ends thereof into close proximity so that they may be
either welded, or, hard soldered, or otherwise joined together. This being done,
I then perforate the inner part for the reception of the several spokes. The
insertion of the spokes is through the holes whereby they rest against the opposite
side of the inner part of the tube. Or, I screw tap the holes & then screw in the.
spokes. I then cast on to them the hub part & box which comprise the centre part
of the wheel.

be performed, to be particularly described and ascertained in and by the following
statement:-

insertion of the spokes is through the holes whereby they rest against the opposite
side of the inner part of the tube, or, I screw tap the holes and then screw in the
spokes. I then cast on to them the hub part & box, which comprise the centre
part of the wheel. The box or centre part of the wheels revolution is a seperate
& distinct part, before being cast into connexion with the hub or stock-cast part of
the wheel, from which the spokes radiate. When the spokes are inserted into the
ring they are then laid in the stocks & cast into or else screwed into the hub or
box. In the application of the tube tyre in substitution of the India rubber one to
what are called spider wheels; after the tube is brazed & the spoke holes formed
the spokes are then screwed into it, & the box as in the ordinary wheel of this kind.
The arrangement of the spokes in their insertion in the hub may be opposite to,
that is, in a straight line with each other, or they may be placed in a serrate order,
& of themselves they may be either solid, or tube, & of other than a parallel shape.
Having now particularly described & ascertained the nature of my said
invention & in what manner the same is to be performed; I declare that what
I claim is
1st Metallic tubing as a tube tyre, or periphery to all wheels for common road
purposes.
2nd; The method of stock-casting together, in two parts, as herein-before
described the centre part of all wheels for common road purposes.
