PROVISIONAL SPEC
Improvements in the Construction of Four Wheeled Road
Vehicles.
I, JAMES HAMILTON KELLY, of 9 Dalmarnock Street, Parkhead, in the County
of the City of Glasgow, Van and Lorry Builder, do hereby declare the nature of
my invention to be as follows:-
This invention comprises improvements in the construction of four wheeled road
vehicles such as lorries, omnibuses, carriages and such like, which are fitted with
turning rings between the fore part of the body and the fore wheels, and refers to
improved methods of constructing such rings which will relieve the strain on the
central connecting bolt and reduce wear and tear.
According to the improvements of this invention these rings which are
constructed at present with flat bearing faces would be formed as follows:-
The lower ring would be formed with vertical flanges on each side all round so
as to form a groove or channel, and the upper ring would work in this groove, and.
would preferably be checked on each side so as to form horizontal flanges which
would rest on the top of the vertical flanges of the lower ring and serve as a cover
to keep out dust.
The groove in the lower ring would also serve to hold a lubricant. The
arrangement of the rings might be reversed and the grooved ring be placed above
the other but the above mentioned is the preferable arrangement and the rings.
might also be formed with flanges only on one side.

Improvements in the Construction of Four Wheeled Road
Vehicles.
I, JAMES HAMILTON KELLY, of 9 Dalmarnock Street, Parkhead, in the County
of the City of Glasgow, Van and Lorry Builder, do hereby declare the nature of
my invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement that is to say:-
This invention comprises improvements in the construction of four wheeled road
vehicles such as lorries, omnibuses, carriages and such like, which are fitted with
turning rings between the fore part of the body and the fore wheels, and refers
to improved methods of constructing such rings which will relieve the strain on
the central connecting bolt and reduce wear and tear.
And in order that my said invention and the manner of carrying same into effect

page_text: or practice may be properly understood I have hereunto appended a sheet of
explanatory drawings in which
Figure 1 is a sectional view of one half of a pair of turning rings,
Figure 2 an inverted plan of the upper ring shown in Figure 1 and
Figure 3 a plan of the lower ring while
Figure 4 is a sectional view of one half of a pair of turning rings of a modified
construction.
According to the improvements of this invention, these rings which are
constructed at present with flat bearing faces are formed as follows:-
As shown in Figures 1 to 3 the lower ring A is formed with vertical flanges on
each side all round so as to form a groove or channel and the upper ring B works
in this groove and preferably is checked on each side so as to form horizontal
flanges which rest on the top of the vertical flanges of the lower ring A and serve
as covers to keep out dust. The groove in the lower ring A may also serve to
hold a lubricant.
The arrangement of the rings may be reversed and the grooved ring A be
placed above the other B but the above mentioned is the preferable arrangement
and the rings might also be formed with flanges only on one side, or' as shown in
Figure 4 in which the upper and lower rings are checked to fit one another.
These improved rings are fitted to the vehicles in any ordinary manner.
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
First. The manufacture and use of turning rings for road vehicles constructed
all substantially as herein described and illustrated by the accompanying
drawings.
Second. The manufacture and use of turning rings for road vehicles constructed
all substantially as herein described and illustrated by Figures 1 to 3 of the
accompanying drawings.
Dated the 14th day of January 1897.
