Measuring apparatus for shot dispensers

In apparatus for delivering accurate amounts of a mixture of at least two liquid ingredients, including ingredient supply means and mixer means to receive, mix and deliver said mixture, measuring means to be disposed between said supply and mixer means to determine the quantity of each ingredient to be delivered to the mixer means, the measuring means comprising:

• a hollow housing;
• a plurality of pairs of ports in said housing, each pair comprising an inlet port and an outlet port and each port having a mouth;
• working surface means extending around and between the inlet port and outlet port of each said pair, the mouth of each port being open to the working surface means;
• transporter means movably mounted in said housing for movement as between a charge position and a discharge position;
• a plurality of cavities formed in said transporter means, each cavity having a mouth;
• means to move said transporter means as between said positions;
• working surface means on said transporter means, the mouth of each cavity being open to last said working surface means;
• the first said working surface means and last said working surface means being in engagement when the transporter means is in said charge and discharge positions and as it moves between the same;
• said cavities respectively being in registry with said inlet ports when said transporter means is in the charge position and being respectively in registry with said outlet ports when the transporter means is in the discharge position and said inlet ports and said cavities being closed off respectively by the engagement of said working surface means when the transporter means moves as between said charge and discharge positions;
• inlet passage means in said housing respectively independently connecting each inlet port to the exterior of said housing for respectively independently delivering ingredients from the exterior of the housing to the inlet ports and thence into the respective cavities;
• outlet passage means in said housing respectively independently connecting each outlet port to the exterior of said housing for respectively independently delivering ingredients from cavities to the exterior of the housing;
• and
• control means operative when the transporter means is in the charge position to control the amount of ingredient material to be received by a cavity and operative when the transporter means is in the discharge position to cause ingredient material in each cavity to flow out of the cavity and into said outlet passage means.
