Machine for making grooves in the ground
First Claim
Patent Images
1. A machine for making grooves in the ground, said machine comprising:
- (a) a rotary disk connected to a mobile chassis and having a continuous peripheral edge devoid of teeth, said disk being mounted freely rotatable, the rotational drive of said disk being provided by contact thereof with the ground when said mobile chassis moves along;
(b) at least one vibrator acting on said disk, said disk penetrating the ground while forcing the matter to be compressed into the bottom and into the side walls of the grooves;
(c) a base plate which can be applied with pressure against the ground, said base plate being arranged orthogonally to the plane of said disk and being provided with a longitudinal space through which a segment of said disk can pass to make said grooves, the lateral edges of said longitudinal space being close to the lateral faces of said disk; and
(d) means bearing on said chassis and firmly pressing said disk and said base plate against the ground, said base plate preventing the matter from the grooves from being thrown outward when said base plate is pressed against the ground.

Abstract
According to the invention:
said machine comprises:
a base plate (8) through which a segment of a disk (4) can pass, said base plate preventing matter from the grooves from being thrown outward;
means firmly pressing said base plate and said disk against the ground; and
the disk (4) is mounted so that it can rotate freely, so as to make in the ground, without removing matter, a recess that corresponds to said groove.

11. A method for making in the ground a groove capable of accommodating a cable or an object having approximately the same size and shape as a cable, which consists of
(a) making a groove in the ground, without removing matter, with a vibrated disk mounted to rotate freely with regard to a base plate pressed against the ground and preventing the matter from the groove from being thrown outward, the rotational drive of said disk being provided by the mobile contact, under pressure, of said disk with the ground; - and
(b) laying said cable in said groove.
