- a table (1) is shown capable of resting on damping means (2) of silent-block type arranged on the horizontal upper face of a supporting frame (7).
- This frame can allow the positioning of one or two or more independent tables, while operating in perfect synchronism.
- the vibrator mechanism referenced as a whole by (3), while on the upper plane of the or each of the tables, is arranged a mold (4) capable of receiving a mass of material (5) intended to be compacted by one or more presses (6).
- the aforementioned vibrator mechanism thus subjects, by its action, the table to a vertical back and forth movement against the silent blocks allowing the compaction of the material.
- the vibratory mechanism consists in placing, under the table or each of the reception tables, rubble stones or all products to vibrate in general, sets of pulleys (8 - 9, 10 - 11) coupled two by two and arranged to receive masses (12) judiciously arranged forming unbalanced and having a vibratory effect during the rotation of the pulleys. These masses are only placed on a diametrical part of the pulleys and more restrictively, in an arc less than their half-perimeter.
- said pulleys are arranged with a plurality of holes (8.1, 9.1, 10.1, 11.1) regularly distributed radially, and in some of which is introduced a mass such as piece of lead or the like. All pulleys are notched and are coupled two by two by a toothed belt (13), while a tensioner (14) ensures the tensioning.
- each body of parallelepiped shape is arranged with internal bores to allow the passage of the axes of rotation of said pulleys and of the tensioner associated with each pair of pulleys.
- a couple of pulleys and tension rollers are arranged in its upper part.
- the block is arranged with brackets or legs (16) capable of being fixed by any means to the lower part of the corresponding table.
- the pulleys (8, 9, 10 and 11) are mounted in pairs (8 - 10, 9 - 11) on two shafts (S1 - S2) which are associated with a phase shifting device capable of to cause the partial rotation of some of the pulleys therebetween and thus the orientation of the masses forming unbalanced.
- Some pulleys are mounted keyed on the trees (S1 and S2) and others are mounted idly on said trees in a judicious arrangement ensuring their placing in opposition.
- the pairs of pulleys (8 - 9, 10 - 11) have thus been arranged for the first table, and the pairs of pulleys ( 18 - 19, 20 - 21) for the second table.
- the pulleys (8 and 20) are keyed on the shaft (S2)
- the pulleys (11 and 19) are keyed on the shaft (S1)
- the pulleys (10 and 18) are mounted idly on the shaft (S2 )

- the shafts (S1 - S2) or their extension also referenced (S1 - S2) for understanding are then arranged in a supporting structure (24) and pivotable at (25) relative to the support casing of the aforementioned phase shift device.
- the motor shaft (S1) is associated at the end with an engine block (26) ensuring the continuous operation of the assembly.
- the supporting structure (24) thus comprises two flanges (24.1 - 24.2) having a triangular profile and braced between them. They allow the fixing of two rollers (29 - 30) arranged substantially in the end portions of the angles, while said structure is articulated on an axis (25) mounted transversely and secured at its ends to a housing or protective casing of the phase shift device.
- the flanges are spaced apart to allow positioning of a pulley (28) in a fixed position mounted on the motor shaft (S1).
- the flanges have an oblong opening (24.3) in relation to the position of said pulley during the oscillation of the bearing structure as will be specified.
- Another pulley (27) is disposed on the shaft (S2) in axial alignment with the pulley (28), outside the pivoting structure, said pulleys (27 - 28) being fixed in position on their respective shafts.
- the two rollers (29 - 30) are arranged on either side of the axis defined between the pulleys (27 - 28).
- the pulley (27) is located outside the volume of the supporting structure.
- a toothed belt (31) is mounted around the pulleys (27 - 28) and the rollers (29 and 30) as illustrated in the drawings.

- the position of the axis (25) is advantageously predetermined and unique so as to maintain a constant width of the belt (31).
- the bearing structure (24) pivoting relative to the frame makes it possible not to use a tension roller as practiced according to the prior art.
- the supporting structure is subjected to an angular pivoting movement or to limited oscillation by means, for example, of a jack (V) fixed to the aforementioned casing and whose rod is associated with one of the flanges cited above.
- An adjustable positive stop (68) angularly limits and preselects the angular value of phase shift.
- This positive stop is for example, as illustrated in FIG. 21, a bar (69) disposed transversely between the flanges (24.1 - 24.2), said stop being associated with a profiled element (70) mounted at articulation with respect to the bearing structure (24) and advantageously, from the axis (25) of articulation thereof.
- the profiled element is itself articulated by means of a jack (71) fixed to the protective casing (32) of the mechanism. According to the development of the rod (71.1) of the jack (71), a position of pivot limit of the bearing structure (24) is defined, thus defining a maximum angulation and causing an appropriate phase shift of the vibratory elements.
- the angular pivotempnt of the bearing structure will have an effect on the positioning of the pulleys (27 and 28) thus causing an action of phase shift of the shafts (S1 and S2) relative to each other.
- an oscillation of the supporting structure by more or less 12.75 ° causes a phase shift of 180o.

- the pulleys (10 and 18) will suffer the same effect and the masses will take a position diametrically opposite to the masses arranged on the pulleys (8 and 20).
