Improvements in Spring Wheels for Vehicles.
I, JULIO LATINI, of 634 Avenida de Mayo, Buenos Aires, Argentine Republic,
Architect, 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:-
My invention relates to a new system of wheels for carriages or any kind of
wheeled vehicles, presenting many advantages over those used at present, on
account of whose hard nature some have attempted to mitigate the severe jolting
which they communicate to the vehicles, by means of pneumatic tires such as
are used in bicycles, but with rare exceptions this method is not practical on
account of its great expense and lack of the necessary qualities of solidity and
durability.
.
My elastic or spring wheel however, unites all the following desirable con-
ditions:
-:
1. Diminished weight of the wheels.
2. A double duration of service on account of the diminishing of the severe
jolting and vibration generally produced in all the bearings and points of contact
below the level of the suspensory springs of the vehicle, which constitute a grave
defect productive of friction and wearing out in ordinary vehicles,
3. A diminished weight in the construction of vehicles using these wheels, by
omitting if desired the ordinary springs.
4. Suppression of the lateral jolting.
5. A material lessening of all disagreeable noise and trembling or violent
vibration.
6. A great decrease in oscillating motion.
7. Economy in the cost.
8. Esthetic superiority.
All these advantages may be better understood by reference to the accompany-
ing drawings, in which equal parts are denoted by equal letters in all the figures:
I have omitted in the representation of the hub or centre of the wheel, the axle,
the box and the screw and nut, these being the same as in ordinary vehicles. In
the drawings:-
Figure represents a lateral view of the wheel, giving a general idea of the
parts which compose it, which are as follows:
-
A. The curved spring spokes made of spring steel, and replacing the wooden
spokes which are at present used in most vehicles.
B. The iron bands or collars which securely fasten the spring spokes to the hub
of the wheel.

page_text: C. The hub of the wheel.
D. The rim or felloe consisting of a single piece of flexible wood curved in
circular form and united at its extremities.
E. The steel tire.
F. The connecting bolt with screw thread and nut to secure the end of the
spring spoke to the rim of the wheel.
G. The triple or bilobate washer of india rubber which isolates the spring
spokes from contact with the rim and from the nut of the bolt F, in order that
the vibrations and jarring of the tire may not be communicated to the body of
the vehicle.
H. The nut of the bolt F.
Figure II represents a vertical section of the wheel on the line L M of
Figure I.
Figure III represents a transverse section on the line N, O of Fig. 1 through
the centre of the union of the spring spoke with the rim or tire.
Figures IV and V represents the same extremity of the spring spoke as seen
from the side and from above respectively.
Figures VI and VII represent front and side views of one of the spring spokes
before being bent into position.
The proportions of the wheel shown in the drawings are for a
66 Victoria" but
nevertheless they may be varied in form and size in order to meet the require-
ments of all classes of vehicles.
Having thus explained my invention, it may be readily understood that the
wheel constituting the said invention, on account of its spring spokes and of their
reciprocal movement in their point of union with the outer rim of the wheel, will
be extremely sensitive to the constant blows or jolts received at any point and
from any direction, and the axle being suspended as it were below the centre of
the wheel, it cannot be affected by the severe jolts which the rim and tire receive
while running over a rough road, and as a consequence, these jolts cannot be
transmitted to the body of the vehicle. The outer circle of the wheel consisting
of the tire and the rim of flexible wood as has already been said, by its flexibility
and lightness resists and adapts itself to the jolts caused by the roughness of the
road, and even the light concussions which it may receive are not communicated
fully to the spring spokes on account of the triple washer which holds the same
gently as if between two pillows, isolating it from all contact with any hard
substance.
Besides, the weight of the vehicle does not rest, as in ordinary vehicles, upon
two or three only of the spokes, but is divided among all the points of union of
the spring spokes, and in consequence, a greater weight can be supported than
with ordinary wheels, without being subject to breaking or other deterioration.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A wheel for coaches or other vehicles, having spring spokes, or spokes in
form of springs, with the object of easing the motion avoiding the troublesome
noise, trembling and vibrations which are usually produced in vehicles provided
with ordinary wheels, substantially as described.
2. In an elastic wheel such as has been mentioned in the first claim, the com-
lination of the hub and the rim or outer circle, which may be of any known
class, with the spring spokes of steel or of any convenient material, which serve
as suspensory springs, either principal or auxiliary, for the vehicle, substantially
as described.
3. In an elastic wheel such as has been mentioned in the first claim, the com-
bination of the spring spokes connected with the hub and the rim of the wheel;
and the triple or bilobate washers of india rubber placed between said spring

herein described with reference to the accompanying drawings and with the objects
indicated.
