PROVISIONAL SPECIFICATION.
An Improved Nave for the Wheels of Carts, Cars, Carriages and like
Road Vehicles..
I, John Edmund MCILROY, Commission Agent, Lisburn Street, Ballynahinch,

This invention relates to an improved nave for the wheels of carts, cars, car-
riages and like road vehicles and it has for its object to lessen friction and improve
the working of the naves of vehicle wheels upon their axles.
In carrying out the invention I make the wheel nave of cast iron or steel and
in two pieces or parts bolted together. The body of the nave has an annular
groove in it formed for the reception of a number of steel rollers which run upon
the axle. The spokes of the wheel do not require to be tenoned to the nave but
are inserted between two circumferential flanges on the two pieces or parts of the
nave and are wedged, bolted or otherwise held in place.

An Improved Nave for the Wheels of Carts, Cars, Carriages and like
Road Vehicles.
I, JOHN EDMUND MCILROY, Commission Agent, Lisburn Street, Ballynahinch,
co. Down, 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 relates to an improved nave for the wheels of carts, cars, car-
riages and like road vehicles and it has for its object to lessen friction and improve
the working of the naves of vehicle wheels upon their axles.
In order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings whereon,
Fig. 1 is a side elevation, partly in section, of the wheel nave.
Fig. 2 is a vertical cross section of the wheel nave and part of the axle.
In carrying out the invention I make the wheel nave of cast iron or steel and
in two parts a, b, bolted together by means of bolts c and nuts c. The part a
of the hub has a recess d in it for the reception of the collar e made one with the
part b. Between the collar e and the axle f is an annular space g for the reception
of a number of steel rollers / which run upon the axle. These rollers are long and
narrow as shown at Fig. 2 and can revolve freely in the annular space.
