Thepresent invention relates to a centrifugal diffusing apparatus for; s preading,. in
the hot or cold state, products for the main-- the material to be spread and receiving ts movement from any suitable driving mechanism, is characterized by the arrangement,'on an axis capable of receiving a continuous r01 tary movement, of walls providing between them zones fed with material to be spread and from which centrifugal force enters in action for projecting the said material by. dispersing it according'to a conical zone the theoretical axis of which mingleswith the axis of rotation of the walls.-
The arrangement. of the rotating wallsis variable with the nature of the product to be spread, its degree of fluidity, or its homogeneity.
The. accompanying drawing illustrates, by way of example only, various forms of con; struction of the diffusing apparatus forming the subject-matter of the invention, 'as well as a form of construction of a mechanism for ac driving this diffusing apparatus. v

Figs. 14 and 15 are views similar to Figs. 10 and 11 illustrating another form of construction of the diffusing apparatus.
-As indicated in theforegoing, the arrangement of the rotating walls of the diffusing apparatus varies according to the material to 10. and Hand relate toa fourth form of conbe spread and the condition of fluidity or of homogeneity of the latter. A vehicle transporting the tank containing the material to be spread is providedwith a mechanism permanently mounted on a rotating axis to which can be rapidly secured the diffusing apparatus proper whic is specially suited to the material to be spread.
Fig. 4} shows a form of construction of the frame of the diffusing apparatus which has the aspect of" a casing 1 made of cast metal, for instance. This casing 1 is provided'with a bed plate 2 for securing itat any suitable place on the vehicle as will be explained later on. It is divided into two distinct chambers by a partition 3 on which is provided a bearing 4 for the axis 5 which receives the diffusing apparatus proper and imparts to the same its rotary movement. The upper chamber constitutes a transmission box, and, in the example illustrated, contains two bevel 'p'inions 6 and 7 respectively secured on the axis 5 and on a transverse shaft 8. The latter,
suitably supported in ball bearings 9 or other types of suitable bearings arranged in the fixed partition 10 and in a wall 11, receives its movement from any suitable source of power and transmits it to the axis 5.
The lower chamber is provided with a tube 12 connected by a flange 13 and any suitable junction means to a pipe for feeding under pressure, or simply by gravity, the material to be dispersed.
In Figs. 1 to 3, it will be seen that the casing 1 is secured by its bed plate 2 on a cross bar 14. arranged at the rear of the frame of the vehicle which carries the tank 15 containing the material to be spread. The vehicle can be of any desired arrangement and its construction does not concern the invention. It can be provided, if need be, with means for heating and stirring the material.
In the example illustrated, use is made of a single diffusing apparatus arranged in the axis of the vehicle. It is obvious and in partioular in the case oi large zones to be covered with. Pwte. t ns-,ma .eri ,that,,,sereral dis, fusing essiaen e em the same vehicle.
The rotation of the shaft can be effected by an independent niotorfnory iand asiillustrated, by the carrying wheels pf thevehiole.

As indicatedin the foregoing, any type" of lao diffusing apparatus can be secured on the driving axis 5, for instance b means of a central socket 27 secured by a key 28 or any other suitable securing means.
The various types of diffusing apparatus which have just been described are only simple examples of realization to which modifications can be made or to which elements can be added, according to the materials to be treated, without departing from the scope of the invention;
The object sought for by the arrangements described is to put centrifugal force in action for dispersing the material and dividing it by partitions and apertures, this material being fed to the diffusing apparatus by gravity or under pressure, by any suitable means.
\Vhat I claim as my invention and desire to secure by Letters Patent is:
1. In a centrifugal diffusing apparatus for spreading products on roadways, a fixed frustum-shaped casing, means for feeding said casing at its part of smallest diameter with the product to be spread, said casing being open at its part of largest diameter, a rotatin member fitted in the said casing, a shaft co-axial with the casing and keyed on the said rotating member, and means to rotate the said shaft.
