Abstract
Abstract A metered fluid-pumping system includes an upright support which may be selectively raised or lowered between two extreme positions. An air-operated pump is attached to the upper portion of the support and is adapted to be lowered within an open-topped bulk fluid container. A flexible hose is attached to the output of the pump to enable selective dispensing of metered amounts of fluid from the bulk container. Structure is provided to meter selected amounts of fluid pumped from the container according to a preselected stored count and then to automatically shut off the pump. Structure is also provided which continuously senses the level of the fluid within the bulk container while providing a nonimpinging wiping action on the interior walls of the bulk container, and then automatically shuts the pump off when the fluid is substantially exhausted from the container without losing the stored count.

Claim 3
Independent Claim
200 words
A system for pumping fluid from bulk fluid containers comprising: a. a pedestal supporting an elongated upright member, b. an extension member mounted on said upright member and movable relative thereto along the longitudinal axis of said upright member, c. air pressure means selectively connectable to said upright member for elevating and lowering said extension member, d. an air-motor-operated fluid pump connected to the upper portion of said extension member for being selectively Raised above and lowered within bulk fluid containers, e. a watertight cabinet rigidly attached to said extension member and containing counter means for monitoring the operation of said fluid pump, f. means for presetting a selected amount of fluid to be pumped and for terminating the operation of said pump means in response to said counter means, said means automatically resetting said system for repeat pumping of said selected amount of fluid after termination of said pump operation, g. means for detecting the level of fluid within the container and for terminating the operation of said pump means when the fluid is substantially depleted within the container, and h. means responsive to the exhaust of said motor for detecting the amount of fluid pumped by said pump.
Claim 4
Independent Claim
200 words
A system for pumping fluid from bulk fluid containers comprising: a. a pedestal supporting an elongated upright member, b. an extension member mounted on said upright member and movable relative thereto along the longitudinal axis of said upright member, c. air pressure means selectively connectable to said upright member for elevating and lowering said extension member, d. an air-motor-operated fluid pump connected to the upper portion of said extension member for being selectively Raised above and lowered within bulk fluid containers, e. a watertight cabinet rigidly attached to said extension member and containing counter means for monitoring the operation of said fluid pump, f. means for presetting a selected amount of fluid to be pumped and for terminating the operation of said pump means in response to said counter means, said means automatically resetting said system for repeat pumping of said selected amount of fluid after termination of said pump operation, g. means for detecting the level of fluid within the container and for terminating the operation of said pump means when the fluid is substantially depleted within the container, and h. means responsive to the exhaust of said motor for detecting the amount of fluid pumped by said pump.
Claim 5
Dependent Claim
