- 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 vibrating mechanism thus subjects, by its action, the table to a vertical movement back and forth 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 be vibrated in general, sets of pulleys (8 - 9, 10 - 11) coupled in pairs and arranged to receive masses (12) judiciously arranged forming unbalanced and having a vibratory effect during the rotation of the pulleys. These masses are arranged only on a diametrical part of the pulleys and more restrictively, according to an arc of a circle less than their semi-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 the 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 between them 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 pulleys (9 and 21) are mounted idly on the shaft (S1).
- each pulley the masses or weights arranged on each pulley are all in the same plane to allow, during operation and rotation of the pulleys, to have a common vibratory effect capable of acting on the aforementioned table or tables causing the compaction of materials, the shafts (S1 - S2) rotating in opposite directions.
- This device which is located outside the receiving frame of the table or tables, comprises shafts in extension of the driving shafts (S1 - S2) associated by any complementary coupling means such as cardan joints (22.1, 22.2 - 23.1 - 23.2).
- 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 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) related to the position of said pulley during the oscillation of the supporting 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 aforementioned bearing structure is mounted with articulation on the axis (25), which is located outside the plane defined by the drive pulleys (27 - 28). Said structure is disposed inside the protective casing (32) of all of these mechanisms.
- 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 the rod of which is associated with one of the aforementioned flanges.
- 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.
- any action on the drive shaft (S1) will cause the partial rotation of the pulleys (11 and 19) keyed onto the shaft, so that the masses or weights located on these pulleys will rotate 180 ° and take a position diametrically opposite to the masses arranged on the pulleys (9 and 21).
- the pulleys (10 and 18) will suffer the same effect and the masses will take a position diametrically opposite to the masses disposed on the pulleys (8 and 20).

- Actions on the X - X 'and Y - Y' axes cause an angulation of these with respect to the axis Z - Z 'defined by the alignment plane of the drive pulley (33) and the tensioner (34), and have the result of gradually causing a separation of the masses (54 ) with respect to the masses (53) as far as coming, according to FIG. 14, in the position of complete diametric opposition thus making it possible to cancel any vibratory effect on the aforementioned table or tables.
