Fuel-lubricating oil proportioner and mixer

A fuel-lubricating oil proportioner and mixer for discharge into a fuel tank, comprising:

• a temporary storage container;
• means for sensing the quantity of fluid in said container and indicating the accumulated quantity at any instant of time;
• a fluid reservoir;
• means for conveying fluid from said reservoir to said container in a stream flow;
• means for initiating and stopping said stream flow to establish a predetermined quantity in said container;
• said means for predetermined quantity being operator-determined;
• means for conveying fluid from said container to said tank in a stream flow;
• and
• mutually exclusive valve means for establishing said flow to or from said container.

A fuel-lubricating proportioner and mixer for discharge into a fuel tank, comprising in combination:

• a lubricating oil reservoir;
• a graduated lubricating oil measuring container;
• a reversible pump connected to said measuring container;
• two-way valve means;
• first conduit means interconnecting said valve means and said pump;
• second conduit means interconnecting said oil reservoir and said valve means;
• third conduit means interconnecting said valve means and the fuel tank;
• means for controlling the position of said valve means enabling said pump to convey a measured quantity of oil from said oil reservoir to said measuring container when said valve means is in a first position and said reversible pump is moving in a first direction and for enabling said pump to convey said measured quantity of oil from said oil reservoir to the fuel tank when said valve means is in a second position and said reversible pump is moving in a second direction.
