<p>1. Device for measuring and pouring out determined quantities of materials comprising a frame (8) and a container (1), - the container (1) being formed by two compartments (2) and (3) situated on either side of the plane of symmetry A-B of the container (1), back to back or able to be n.ade integrally, - the said container (1) being movable and able to rock in an oscillatory movement about an axis (6) passing through the plane of symmetry A-B of the container (1), the axis (6) being horizontal and arranged so as to be supported on the seatings (7) of the frame (8), - this container (1) being, in addition, provided with : - a means (9) able to control the amplitude of its oscillations on either side of the vertical, - a means (10) enabling its rocking couple to be regulated and controlled, - and a means (11) ensuring that the rocking couple of the container (1) is identical about the axis (6) and on either side of the vertical, characterized in that : - the compartments (2) and (3) of the container (1) enclude side pieces which are constituted respectively by movable shutters (4) and (4') and (5) and (5') : - the means (9) able to control the amplitude of the oscillations of the receptacle (1) is formed by a stop (19) placed at the top (16) of the container (1) and in the plane of symmetry A-B, which stop (19) co-operates on the one hand with a slider (20) which may be fixed to the frame (8), provided with catches (21) and (22) limiting the travel of the stop (19) ; - the means (10) enabling the rocking couple of the container (1) to be regulated and controlled is constituted by an adjustable weight (23) arranged at the level of the upper part of the container (1), - the means (11) ensuring that the rocking couple of the container (1) is identical about the axis (6) and on both sides of the vertical is constituted by an adjustable weight (24) arranged at the level of the lower part of the container (1).</p> |
