Abstract
Abstract Chamber-defining means define a closed chamber, a sealing inlet to and a sealing outlet from said chamber. Stock-feeding means are provided for continuously moving stock to be oiled through said inlet, chamber, and outlet along a predetermined path. A row of nozzles open in said chamber and are spaced apart transversely to said path and directed toward said path and operable to discharge an oil-air mixture toward said path. Each of said nozzles comprises a needle, which is displaceable to vary the rate at which said oil-air mixture is discharged from said nozzle. An oil conduit and a compressed-air conduit are connected to said nozzles. An automatic control system is provided to control the rate at which said oil-air mixture is discharged from said nozzles in proportion to the speed of travel of said stock in said chamber. Said control system comprises a sensing roller engageable with said stock and adapted to be driven thereby at a speed which is proportional to said speed of travel, a tachogenerator arranged to be driven by said sensing roller and to produce an output signal representative of said speed of travel, an actuator, a controller arranged to receive said output signal and to control the operation of said actuator in response to said output signal, and a linkage operatively connecting said actuator to said needles and arranged to displace said needles in response to a change of said speed of travel resulting in an operation of said actuator.
