PROVISIONAL SPECIFICATION.
Improvements in Wheels for Carriages and other Vehicles.
I, WILLIAM STEWART of 124 Harmony Row, Govan, Glasgow in the County
of Lanark, North Britain, Contractor, do hereby declare the nature of this inven-
tion to be as follows:-
--
This invention relates to improvements in wheels for carts, carriages and other
vehicles and consists in constructing the wheel of metal whereby deterioration of
the present wheel through the use of wood is obviated.
In the carrying out of my invention I construct the spokes of steel or other metal
tubes which are screwed onto studs formed upon the nave. The felloe of the wheel
may be secured to the spokes by means of studs. With a rubber tyre I prefer to
use a felloe of U or V section the stud being passed through the bottom of such a
felloe into the end of the spoke. The ordinary bush can be inserted inside the nave
and the bush may be formed with a flange or flanges, or key, fitting into corre-
spondingly shaped recesses formed in the nave so as to keep the bush secure within
the nave.
The studs on the nave may be forged thereon or they may be tapped into the
nave. The bush may be made of the ordinary brass, gun metal or cast iron and the
rest of the wheel of forged iron or steel.

COMPLETE SPECIFICATION.
Improvements in Wheels for Carriages and other Vehicles.
I, WM. STEWART of 124 Harmony Row, Govan, Glasgow in the County of
Lanark, North Britain Contractor 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 which relates to improvements in wheels for carts, carriages and
other vehicles, consists in so constructing such wheels of metal that they are lighter,
stronger and more durable and also the deterioration of the present wheel through
the use of wood is obviated.
Figures 1 and 2 are part front elevation and section respectively of a wheel
constructed according to my invention.
Referring to said drawings I construct the nave A of metal and I provide it with
a number of screwed studs B which may be formed in one with the nave or as shown
tapped therein; the outer extremities of said studs B are then screwed into the ends
of the spokes Cwhich are preferably hollow steel or other metal rods or tubes. To
the outer ends of said spokes C, I attach, preferably by means of tapped screws D,
the felloe E which may be of any desired shape; though with an india rubber
tyre F as shown I prefer to employ a felloe of a U or V shape in section, the
screws D being passed through the bottom of such a felloe into the ends of the
spokes C as shown in Figure 2. A bush may be inserted in the nave but I prefer to
form the bush and nave as one as shown. When the bush is made separate from
the nave it may be formed with one or more flauges or with keys which fit into
corresponding grooves or recesses formed in the nave in such a manner as to retain
the bush therein; and to facilitate oiling I may provide an oil hole and screw pin
arrangement G as shown.

page_text: The nave and bush may be made of brass, gun metal, iron or other metal, and the
remainder of the wheel may be made of iron or steel. The tyre F may be made
of india rubber or other material and of any desired shape & construction whether
solid or pneumatic.
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 :-
1st. Constructing the wheels of carriages, carts and the like of metal substantially
in the manner as, and for the purposes as hereinbefore described and shown in the
drawings.
2nd. In the construction of the wheels of carriages, carts and the like, the
arrangement, construction and combination of the nave A, spokes C, and felloe E
with tyre F, all substantially as and for the purposes hereinbefore described and
shown in the drawings.
3rd. In carriage, cart and similar wheels, forming the spokes of hollow metal rods
or tubes, substantially as and for the purposes hereinbefore described and shown in
the drawings.
