Constant depth reservoir

An apparatus for regulating an amount of a friction reducing lubricant applied to a surface of a workpiece, the apparatus comprising:

• a primary reservoir, for containing the friction reducing lubricant, having an opening;
• a constant depth reservoir connected to said primary reservoir through said opening for receiving the lubricant;
• said constant depth reservoir including a liquid drop control valve, an orifice and a valve and float assembly;
• said liquid drop control valve capable of opening and closing said orifice;
• said valve and float assembly capable of opening and closing said opening;
• a sight feed having an inlet connected to said constant depth reservoir through said orifice, an outlet connected to a venturi nozzle chamber having a nozzle, and an atmospheric vent;
• a means for supplying compressed air to said nozzle through said nozzle chamber for dispersing the lubricant from said outlet.

An apparatus for dispersing a lubricant consisting essentially of:

• a primary reservoir having a first orifice;
• a needle valve engageable with said first orifice;
• a low volume constant depth reservoir having a second orifice;
• a float assembly in said low volume constant depth reservoir;
• said float assembly and needle valve capable of variably closing and opening said first orifice;
• said low volume constant depth reservoir being located beneath said first orifice;
• a liquid drop control needle valve being movable with respect to said second orifice;
• a sight feed vented to atmosphere, having an inlet and an outlet;
• said inlet being connected to said second orifice of said liquid drop control needle valve;
• a venturi nozzle having first and second inlets and an outlet;
• said first inlet of said venturi nozzle being removably attached to said outlet of said sight;
• a pressurized air source;
• said second inlet of said venturi nozzle being connected to said pressurized air source;
• whereby when said float assembly moves up and down in said low volume constant depth reservoir, said float assembly opens and closes said needle valve to a varying degree, and lubricant is transferred from said primary reservoir to said low volume constant depth reservoir by means of gravity feed.

An apparatus for dispensing a lubricant, the apparatus comprising:

• a primary reservoir containing a lubricant and having a first orifice connected to a constant depth reservoir containing a float assembly that is mechanically connected to a needle valve that is engageable with the first orifice so that the float assembly and the needle valve act in conjunction to variably open and close the first orifice;
• whereby the amount of lubricant that passes through the first orifice varies in relation to the degree to which the float assembly and the needle valve open and close the first orifice;
• the constant depth reservoir further including a lubricant drop control valve connected to a sight feed vented to atmosphere, said sight feed receives said lubricant regulated by said lubricant drop control valve;
• said sight feed having an outlet connected to a venturi nozzle;
• the venturi nozzle including a first inlet connected to a pressurized air supply and a first outlet to disperse said lubricant. d
