Abstract
Abstract A device for accurately proportioning and mixing a liquid medicament or the like into drinking water for animals includes a reservoir in which the medicament and water are mixed, a water inlet supply capable of being adjusted to a desired predetermined flow rate, and a pumping arrangement for continuously injecting a predetermined flow rate of medicament into the reservoir container. A control device is arranged for initiating the water and medicament flow automatically as the demand for drinking water exists. A pre-set timing device is incorporated in the medicament flow circuit to permit cyclic feeding of the medicament to the water, if required. An elapsed time indicator in the water circuit permits calculation of the total quantity of water used.

Claim 1
Independent Claim
305 words
A liquid mixing apparatus for accurately proportioning additives into drinking water for animals, such as poultry, livestock and the like, said mixing apparatus comprising: a. support means; b. reservoir means for mixing and holding a water-additive solution mounted on said support means; c. water supply means for delivery of a quantity of water to said reservoir means at a predetermined rate; d. means for storing and injecting a quantity of additive to said reservoir at a predetermined rate proportionate to the flow rate of the water, said additive storing and injecting means includes a storage means for storing a prepared quantity of liquid additive solution mounted on said support means below said reservoir means so as to collect overflow from said reservoir means, pump means arranged for drawing the additive from the storage means and and adjustable regulator means connected to the output of said pump means whereby the predetermined flow rate of additive solution can be injected directly into the reservoir means, the output of said pump means further including a pressure by-pass means whereby the additive can be returned to the storage means when the pressure in the additive injecting means exceeds a predetermined pressure; e. means connected to said reservoir means for distributing the solution to a watering area for said animals whenever a demand for drinking water exists; and f. means for automatically controlling the flow of water and additive to said reservoir means for continuously mixing whenever the solution within the reservoir means is withdrawn below a predetermined level by said distributing means, said control means includes means for operating said pump means continuously when desired so that the prepared liquid additive when not injected into the mixing reservoir can be recirculated through the pressure by-pass means to maintain any insoluble particles within said additive in a state of suspension.
Claim 2
Dependent Claim
