Improvements in Wheels for Vehicles.
I, PIERRE SAMOIS, of Peruwelz, Belgium, Inventor, do hereby declare the nature
of this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement:-
The present invention relates to improved wheels applicable to vehicles of all
descriptions, in which the tires are fitted on cold without the use of any mech-
anism, and are so constructed that spokes, or segments of the felly, can be
replaced at will, without it being necessary to dismount the wheel, or to remove
the iron band or tire therefrom.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawings thereof, reference being had to letters
and figures marked thereon.
Fig. 1, is a view in elevation of an improved wheel with plain spokes, for light
vehicles.
Fig. 2, is a section of the same figure following a plane passing through its axis.
Fig. 3, is a view in elevation of a wheel constructed upon the same principle
as that shown in Fig. 1, but with crossed spokes for vehicles intended for heavy
loads.
Fig. 4, is à section of the same wheel following a plane passing through its
axis.
Fig's. 5, to 9, show various details of construction of the two wheels.
The wheel which forms the subject of the present invention consists: firstly,
of parts borrowed from ordinary wheels, the iron tire, the wooden felly, and the
spokes, also constructed of wood, but provided at their inner ends, towards the
centre of the wheel, with a special arrangement which will be described during
the course of the present description; secondly of a special nave or hub which
forms the principal characteristic feature of the invention.
The wheel may be constructed in two manners: first, with plain spokes for light
vehicles; 2nd with crossed spokes for vehicles for transporting heavy loads such
as omnibuses, field guns, etc.
In the case of wheels with plain spokes the nave or hub, constructed completely
of metal, carries a plate L', shown in section in Fig. 2, and in detail in Fig. 6,
and a plate M shown in detail in Fig. 7. These two plates are placed in juxta-
position the one to the other upon a barrel or axle box N which turns freely upon
the axle, which latter is not shown in the drawings. This barrel or axle box
has cast or formed on it two longitudinal tenons or ribs which engage in corre-
sponding grooves or recesses provided in the plates L and M, and which prevent
these latter from having any rotary movement imparted to them other than that
communicated by the drawing or traction of the axle.
In the plate M, twelve radial slots or mortises are provided which are intended
to receive trapezoidal shaped bolts P; in the plate L are provided twelve holes
corresponding exactly with the bottoms of the before mentioned mortises.
The screw threaded extremities of the bolts P are directed towards the exterior

page_text: of the wheel. The other extremities, which are of a trapezoidal form, receive the
spokes the ends of which abutting against the said bolts, are fitted in shoe
pieces T which facilitate the sliding of the said spokes upon the said bolts or
wedge pieces. A metal collar R is placed round the bolts P. This collar is per-
forated with holes which receive bolts S, which bolts to the number of twelve
pass between the spokes and through corresponding holes provided in the plate L,
and are tightened by means of nuts which latter bear against the exterior face
of this plate. These bolts retain the spokes between the collar R at one side and
the plate L on the other.
Between the segments of the felly are arranged tightening wedge pieces U for
use in case the pressing of the segments of the felly against the tire should produce
a certain amount of separation.
The wheel especially constructed for the large classes of vehicles is based upon
the principle which has been herein above described; the nave or hub being only
somewhat modified. The nave or hub, in this case, carries two plates L' and M
(Figs. 3, and 4,) placed the one in juxtaposition to the other upon the barrel or
axle box N which is practically the same as that of the wheel described in the
first place. These two plates are alike and are symetrically mounted upon the
barrel or axle box; one of the two is shown in detail in Fig. 9.
Between the two plates, is fixed upon the barrel or axle box a support 0
(Figs. 4, and 8,) in which twelve radial slots or mortises are provided alternately
agreeing with six holes perforated in the plate M¹, and with six holes perforated
in the plate L¹ in such a manner that the pressure bolts or wedge pieces P, to
the number of twelve, have their screw threaded portions turned towards the
exterior of the wheel, and the other extremities which are of a trapezoidal shape
receive the shoe pieces T which terminate the extremities of the spokes.
A metal collar R¹ placed round the mortised support 0, maintains a certain
space between the alternating spokes. Bolts S serve to insure the position of the
spokes between the collar R₁ and the plates L' and M¹.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is: -
1
1. A wheel applicable to vehicles of all kinds or classes, characterized by a
nave or hub entirely of metal consisting of two plates of circular form fixed upon
a barrel or axle box which rotates freely upon the axle of the vehicle, and which
possesses two longitudinal ribs or tenons engaging in corresponding grooves in
the plates so as to fix the latter upon the said barrel or axle box, one of
the plates possessing radial mortises or slots and the other through or passage
holes corresponding to the bottonis of the said slots or mortises, the said mortises
or slots receiving each a bolt of a trapezoidal form terminated by a cylindrical
part screw threaded and passing through the corresponding hole in the other
plate, and tightened by means of a nut upon this latter; by spokes possessing at
their extremities, which are directed towards the nave or hub, metal shoe pieces
each of which rests upon one of the trapezoidal bolts, the spokes being tightened
or pressed against the felly, at will, by means of the tightening of the said trape-
zoidal bolts; by a collar surrounding the first named plate, or mortised or slotted
plate, and connected to the second plate by .bolts passing between the spokes and
insuring the fixture of the said spokes; the mortised or slotted plate forming the
interior face of the nave or hub, the felly being provided with screw wedge
tightening pieces placed between its segments for use in cases in which a certain
separation is produced by the pressure of the segments against the tire; and the
wheel thus constructed being especially intended for light vehicles.
2. In a wheel such as that claimed in the first claim, the arrangement of crossed
spokes, for the special application of the wheel to heavy vehicles and to field
guns, characterized by two plates substantially similar symetrically fixed upon

page_text: the barrel or axle box rotating freely upon the axle of the vehicle, between which
plates is keyed upon the said barrel or axle box a supporting plate having twelve
radial slots or mortises, six of which slots or mortises correspond, taken two by
two on the supporting plate, with six through or passage holes perforated in one
of the above mentioned plates, and the other six alternately with the first, corre-
sponding with six holes perforated in the other plate, six trapezoidal tightening
bolts similar to those employed in the form of construction claimed in the first
claim, being placed in the first six slots or mortises and their screw threaded
extremities tightened by means of nuts upon one of the plates, and six other
similar bolts, placed in the other slots or mortises, having their screw threaded
extremities tightened upon the other plate, a ring being fitted round the above
mentioned bolts for the purpose of maintaining the separation of the spokes, and
a series of cylindrical bolts, passing through the two plates and the ring, insuring
the fixture of the spokes, which are placed through the medium of metal shoe
pieces, similar to those claimed in the first claim, alternately upon trapezoidal
tightening bolts.
