PPARATUS FOR OILING TEXTILE I MATERIALS This invention relates to improvements in an apparatus for applying softening or lubricating oil to textile materials prior to fabricating same and the principal-object of the invention is to provide means for automatically controlling the delivery of oil to the textiles taken from the picker feeder and delivered to the picker in the initial stage of handling the textile material to :be fabricated into yarn.

A further object is to provide an equipment which may be accurately adjusted to deliver any required volume of oil to the textile material being transferred.

' A still further object is to provide an apparatus which will, in the event of failure of any of the delivery spray nozzles, automatically increase the flow through the remaining operating nozzles so that the required amount of oil delivery will be maintained.

The principal feature of the invention consists in arranging a flow control valve in the feed pipe leading from the pressure pump for feeding the oil emulsion to the spray nozzles for delivering the oil to the textile material being transferred, and controlling said valve by means of a slow speed reversible motor operated member, the operation of which is controlled by an adjustable flow meter arranged in the feed pipe between the pump and the control valve. I

In the manufacture of textiles from wool or other materials it is necessary to apply a stipulated quantity of oil emulsion to a given quantity of material to facilitate manufacture and the oil is sprayed upon the material from suitable nozzles while it is being transferred from storage to the initial picker machine.

f It has been the customary practice to control the flow of oil from the nozzles by the manual manipulation of a control valve while a constant pressure is maintained in the supply line by a I J- Frederick W.

of the delivery nozzles become clogged,'the amount of oil delivered to the material will be inadequate and ununiform and in any event the flow. control is arbitrary being dependant upon the judgement of the attendant of the apparatus.

In carrying the present invention into effect, the usual form of picker feeder I feeds the'fibrous materials in a broad sheet from the feed pit 2 and delivers same to the apron 3 of the picker machine 4.

Arranged over the feeder apron 3 of the picker 4 is a transverse spray pipe 5 which is provided with a plurality of suitable spray nozzles 6 which direct the oil emulsion in a fine spray over the material.

The spray pipe 5 is connected by a pipe 7 to the pressure feed pump 8 which is connected with an oil emulsion tank 9.

A flow control valve I is arranged in a suitable location intermediate of the length of the pipe I. This valve is a direct action valve which is spring actuated to open and is of a well known construction and need not be described in detail.

Arranged above the valve In and operatively engaging the upper end of the spindle thereof, is an eccentric disc or cam II Which is mounted on the shaft of a reversible slow speed motor mechanism I2 which may be of any suitable type the details of which form no part of this invention.

Between the valve I0 and the feed pump 8 the feed pipe I is provided with the spaced-apart branch pipes I3 and I4 between which is arranged a normally closed shut-off valve I5.

Connected between the ends of the branch pipes I3 and I4 is a suitable form of fluid flow meter I6, presferably of the type hereinafter described which measures the flow of fluid therethrough.

' Floatably supported within the diverging tube II of the flow meter I6 is a cupped member I8 from which a rod l 9 extends upwardly into a tube 20, said rod carrying a permanent magnet ex tension 2| which is in rod form. As is well understood during fluid flow through the meter with the valve I5 closed the cup-shaped member or float I8 assumes a position in the diverging or tapered tube I1 whereby the annular opening between the float and tube wall is such as to provide the required flow area corresponding to the flow rate through the tube. Arranged outside of and spaced from the tube 20 is a casing 22 which has a longitudinal slot 23 in which is slidably mounted a block 24. This block may be secured in any desired position in the length of the casin 22. Suspended from the block 24 is a small mercur switch 25 in tube form in which a magnetically controllable pivotal contact member is mounted. The pivotal member when influenced by the magnetic field of the movable magnet is caused to tilt to close an electric circuit through the wires 26 connected through a suitable transformer 2i to the solenoid of a double throw relay 28 so that when the flow of oil through the float meter it reaches a given rate or amount the cupped member 18 has operated to move the magnet to operate the switch to close the relay circuit.

Contacts 29 are arranged in the relay to be closed when the relay is energized as described controlled magnet effects the breaking of the circuit through the switch 25, the solenoid of the transformer 2's" releases its plunger to break the circuit to the cam operating motor but it immediately closes the contacts 29 of the relay to direct current through the motor I2 to reverse the movement of the valve operating cam The valve ID is operated by the cam H to slowly choke the oil fiow when such flow becomes excessive and operates the meter I6 to close the motor circuit and when the flow decreases the meter is reverses the motor circuit and the spring-opened valve follows the slowly moving cam and again increases the flow. The result of this operation of the motor I2 is that while the machine is in operation the motor is slowly but continually hunting that is, moving the cam i2 slowly back and forth thus manipulating the valve to maintain a substantially constant flow of oil to the nozzles.

If however a nozzle becomes clogged the flow will decrease and the valve control motor will continue to operate to permit the valve to open further and increase the flow through the other nozzles maintaining a substantially constant flow through the meter and a constant volume of oil deposited on each unit length of material fed beneath the nozzles.

The device as herein described is extremely simple and utilizes well known standard mechanisms but it has been found in practice to operate very effectively and maintains an automatic flow control which ensures the textile materials being uniformly treated at all times that is, each unit length of material passing beneath the spray nozzles will receive an equal volume of oil independent of the plugging of one or more of the nozzles. It will of course be understood that any unevenness in the actual oil distribution over the surface of each unit length of material caused by the blockage of a nozzle is equalized in the handling and mixing of the material in subsequent operations which efiect the spreading of the oil uniformly throughout the material fibres.

The control valve has been herein shown as being operated by a motor operated cam but it will be appreciated that such control valve might be operated hydraulically and the hydraulic mechanism controlled by suitable means operated through the relay.
