Machine for filling containers

A machine for filling a plurality of containers by twos with a liquid which comprises an empty container infeed section, a filling section and a full container discharge section, the filling section comprising an annular tank for the liquid, rotatable around its own axis of symmetry, and a number of pairs of filling valves arranged substantially on a radius from the axis of symmetry of the tank and having underneath each pair of valves support mechanisms for the containers, rotatable in conjunction with the valves, which support mechanism receives containers from a transfer means in a first transfer section between the infeed and filling sections, the support mechanism comprising apparatus capable of changing vertical position to engage and disengage the filling mouth of the containers with the filling valves before the containers arrive at a second transfer section between the filling section and the discharge section, said empty container infeed section being equipped with an infeed spider apparatus capable of receiving and discharging empty containers by twos in a substantially radial alignment with respect to the axis of the infeed spider and with said infeed spider apparatus comprising a star mounted on a propelling axle on which a series of arms are mounted in an angularly movable manner, the arms jutting out from the periphery of the star and supporting a roller each, the rolling surface of each roller resting on a cam surface, stationary with respect to the machine, the aforesaid star apparatus having peripheral cavities which, in combination with the said arms, are capable of receiving two containers, the centers of which are substantially on a radius of the center of the aforesaid propelling axle, and of delivering them in an arrangement in which their centers are substantially on a radius of said symmetry axis whereby the containers are transferred from the empty container infeed section to the container filling section and a full bottle discharge means capable of withdrawing the filled contained by twos at a second transfer section between the filling and discharge sections.
