Abstract
Abstract A motor-transportable plant for delivering substances for treating roadways or the land, in which a tank is divided by a wall into two separate chambers, each accessible through a manhole, and which can be connected together by opening valves provided in the wall; one of said chambers comprises stirring means for a liquid and a solute contained in the chamber, and means for withdrawing the formed solution and feeding it to the outside of the tank, a motor being provided for said withdrawal and for feeding the solution; the second chamber comprises stirrer means and means for withdrawing a solid material contained in the chamber and for feeding it to distributors therefor; said stirrer and withdrawal means are extractable from the chamber through an aperture closable by means of a suitable cover; the tank is supported by a rigid quadrilateral frame provided with legs which can extend by hydraulic control and are each provided with orthogonal shafts which are inserted into the cross members of the frame to define, using locking means, respective horizontal and vertical positions of the legs in which these latter either lie against or are distant from the frame, each shaft having a length greater than one half the length of the cross member into which it is inserted, and a diameter different from the opposite shaft which is also inserted into the cross member, so that one shaft can itself be inserted into the other when the legs lie against the frame.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
255 words
A plant composed of multi-functional apparatus for delivering substances for the treatment of roadways or the land, characterised by comprising a tank divided by a wall into two separate chambers each accessible through a manhole, and which can be connected together by opening valves provided in the wall, one of said chambers comprising agitator means for a liquid and a solute contained in said chamber so as to form a complete solution of the solute in the liquid, motor means being provided for withdrawing and delivering the solution, the second chamber comprising second agitator means for solid material contained in the chamber, and means for withdrawing it and feeding it to distributor means therefor, said second agitator and withdrawal means being extractable from the chamber through an aperture which can be closed by means of a suitable cover; the tank being supported by a rigid quadrilateral frame provided with legs which can extend under hydraulic control and are each provided with orthogonal shafts which are inserted into the cross members of the frame in order to define, by the use of locking means, respective horizontal and vertical positions of the legs in which they lie against or are distant from the frame, each shaft having a length greater than one half the length of the cross member into which it is inserted, and a diameter different from the shaft opposite which is also inserted into the cross member, so that one shaft can be inserted into the other when the legs lie against the frame.
Claim 2
Dependent Claim
255 words
A plant composed of multi-functional apparatus for delivering substances for the treatment of roadways or the land, characterised by comprising a tank divided by a wall into two separate chambers each accessible through a manhole, and which can be connected together by opening valves provided in the wall, one of said chambers comprising agitator means for a liquid and a solute contained in said chamber so as to form a complete solution of the solute in the liquid, motor means being provided for withdrawing and delivering the solution, the second chamber comprising second agitator means for solid material contained in the chamber, and means for withdrawing it and feeding it to distributor means therefor, said second agitator and withdrawal means being extractable from the chamber through an aperture which can be closed by means of a suitable cover; the tank being supported by a rigid quadrilateral frame provided with legs which can extend under hydraulic control and are each provided with orthogonal shafts which are inserted into the cross members of the frame in order to define, by the use of locking means, respective horizontal and vertical positions of the legs in which they lie against or are distant from the frame, each shaft having a length greater than one half the length of the cross member into which it is inserted, and a diameter different from the shaft opposite which is also inserted into the cross member, so that one shaft can be inserted into the other when the legs lie against the frame.
Claim 3
Dependent Claim
57 words
A plant as claimed in claim 1, characterised in that the agitator means of the first chamber are in the form of tubular supports, in each of which there rotates a motor-driven shaft provided at one end with a disc rigid therewith and dipping into the chamber, the support being able to be swivelled inside the chamber.
Claim 4
Dependent Claim
88 words
A plant as claimed in claim 1, characterised in that the means for dissolving the solute in the liquid are constituted by a pipe with a filter, the pipe dipping into the chamber and connected to a pump which feeds the solution to a second pipe provided with bores and located in said chamber, and passing through the wall to continue into the second chamber so that it can be made active or inactive in this latter by opening or closing a valve disposed in said solution pipe.
Claim 5
Dependent Claim
77 words
A plant as claimed in claim 1, characterised in that the second agitator and withdrawal means of the second chamber are constituted respectively by a shaft comprising protuberances and by a worm, these being rotated by a motor and supported at their ends by two plates connected together by longitudinal cross members in such a manner as to form a frame which can be inserted through an aperture in the tank at the end of the chamber.
Claim 6
Dependent Claim
61 words
A plant as claimed in claim 1, characterised in that the distributor means for the material contained in the second chamber are constituted by a spreader disc which can be adjusted in level relative to the road surface and is supplied with the material fed by the agitator means, in a quantity which can be controlled by manually operated valve members.
