17 Claims. (01. 19-66) use with machines used in manufacturing raw.

cotton and other fibrous materials into yarns or cloth in which form it is usually placed on the market. In machines and methods heretofore used in oiling cotton and other fibrous materials it has been diflicult to have the oil penetrate evenly into the cotton or other fiber so that substantially all of the fiber was given the same amount of oil.

An object of my invention is to provide a device by means of which oil will be evenly distributed over the fiber and caused to penetrate evenly throughout the fiber.

A further object is to provide an improved pump for supplying the oil to the fiber. I

A still further object is to provide a machine for moistening cotton or other fiber either in its raw state or after it has been converted. into threads.

Further objects and advantages will become apparent as the description proceeds.

To simplify the description and to avoid needless repetition, the word cotton will be used but the machine is designed to treat any similar fibrous material, and should be so understood.

Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts,

cleaned in previous operations, is delivered by The cotton, generally after having been means of a conveyor 10 through rolls 11 to beater chamber 12 in which it is operated upon by heaters 13 which separate the fibers from the mass and straighten them as they are separated so that the fibers, after having been acted upon by the beaters, are in a highly divided state. The usual perforated grid 14 being positioned beneath the beater chamber 12. From the beater chamber the cotton is carried through a chamber 15, thence through rollers 16 and on through the machine. The other mechanism which engages the cotton forms no part of the present invention and therefore will not be, described further. My invention provides mechanism shownas a whole at 17 for delivering oil upon the cotton at a point where it will most completely impregnate the greatest number of fibers of the cotton. This is at the point where the cotton is subjected to the treatment in the beater chamber 12 to separate and straighten the fibers. The mechanism for supplying oil-to the cotton will now be described.

This consists of an air manifold 18 to which air under suitable pressure is supplied from any suitable source. Attached to the manifold 18 are outlet tubes 19 in the lower end of which are positioned nozzles 20. The nozzle 20 has a restriction at 21 and the outer end of the nozzle is slotted at 23 as shown in Fig. 3 or is provided with a number of small holes 22 as shown in Figure 4. In either case the oil issues from the nozzle in a sprayed jet which is either in sheet form or in the form of a number of radially spreading jets. As shown in-Figure 1, the ends or the nozzles are disposed within the beater 9 chamber '12 and are so positioned as tor-direct the spray of. oil upon the cotton fibers a't' the point or points where they are acted upon; by the heaters 13, so that the heaters not only separate and straighten the fibers but tend to mechanically distribute the oil over the fibers as they are separated. The tubes 19 are-provided with oilconne'ctions at 24 to which oil pipes 25 are attached in any suitable way as by unions'26. Oilunder pressure is supplied toeach of the tubes 25 by means of a pump shown as a whole at 27. This pump consists of a number of pumping chambers'each having an inlet and a discharge port. The inlet'ports are connected to a common inlet manifold 28 to which oil may be supplied in any suitable way. The outlets of the pumps are connected to pipes 25. The pumps are of the reciprocating type in which solid pistons opf erate. The pistons are all connected to-a common -operating head 29 which is guided upon suitable guides 30 and 31. The head is operated by means of a link 32.

The means for reciprocating the pump pistons is shown in detail in Figures 5 and 6 and consists of an arm 33 pivoted to the frame of the pump at 34. To the hub of this arm is attached a short arm 35 to the outer end of which is attached the operating link 32. An arm 36 pivots on a; shaft 3'7 on the frame of the machine and has on its lower end a gear segment 38. Secured on the other end of the shaft 37 is an arm 39 which is slotted and pivotally connected by means of a bolt 40 with the arm 33. The pivotal bolt 40 may be adjustable longitudinally of the arms 33 and 39"to provide means for Varying the length of stroke imparted to the pump pistons. The gear segment 38 is operated by means of a train of gears 41, 42 and 43 in which a small pinion operates on a larger gear to provide speed reduction in a well known manner. The gears are driven by a pinion 53 operating on a pinion 44 which meshes with the gear 41. Pinion 53 1am the inner end of a shaft 45 on the outer end of which is a .sprocket 46 over which operates a sprocket chain 47 which is driven by a sprocket 48 upon the outer end of a shaft on which roller 49 is mounted. The sprocket chain 47 is continuously driven. The pinions 53'and 44 are contin uously driven, pinion 41 is movable axially to en-' g ze and disengage the pinion 44. The pinion 41is mounted on a shaft 50 on the other end of which is a pinion 51 which engages with and drives the gear 43. The: shaft 50 is movable axially to engage and disengage gear 41 from the gear 44 by means of a rocker 52 which is pivoted at 54 on the frame of the machine. A spring 55 engages the other endof the rock arm and tends to hold the gear 41 in mesh with the gear 44. These gears are moved out of mesh by means of a rod 56 on which is secured a collar 57 engageable with the end of the arm 58. The rod 56 is connected to a'lever 59 by means of which it is operated, this lever being a well known part of a machine for rolling cotton of the type to which this invention is applied. A weighted arm 66 is provided for resetting the pistons when the clutch has been released. A stop 6'7 limits the backward stroke.

' When the rod 56 is operated to control a clutch which controls movement of the cotton material the pump is stopped to stop the supply of oil being sprayed upon the top of the material.

- oughly mixes with the cotton and so oils all of Instead of placing the oil nozzle as shownat 17 in Figure 1 it .may be positioned at the point X and as shown in detail in'Figure 10 in which case the oil is sprayed upon the cotton in the chamber 15. In this position, however, the oil also thormight supply oil at one, two or all of these positions if occasion seemed to require it.

In Figure 9 is illustrated a type of machine for supplying moisture to cotton in the form of threads in which the thread 60 passes over rollers 61 and 62 after it has undergone substantially all of its formative operations and passing out through a relatively low tunnel 63 where water nozzles or jets 64 are positioned to deliver water upon the moving sheet of threads. The nozzle is preferably positioned to project water in the direction opposite to that in which the thread is moving, the thread, however, is thoroughly coated with a film of water and has the water evenly distributed over its surface. The nozzle 64 is that shown in detail in Figure 2 and the water supplied to the nozzle may be supplied by a pump similar to that which supplies oil to the oil nozzle. An air duct 68 is provided through which a blast of air is blown by a fan, not shown. This blast of air carries the moisture back into the tunnel and assists in distributing it evenly on the fiber.

In applying the water and applying the oil air under pressure is necessary. This air may be under relatively low pressure and in passing through the nozzle 19 it contacts with the oil entering from the port 24. In actual operation the oil issuing from the port 24 will tend to adhere to the sides of the nozzle 21. Thevelocity of the air issuing from the manifold 18 will tend to stretch out the oil film and the air issuing through the restricted nozzle 21 will tend to break up the stretched film of oil into a fine mist or spray. The oil is very thoroughly atomized by the air and is in tit condition to be sprayed as a fine mist out through the perforated or slotted nozzle 22 or 23. In any case the oil is rendered sufficiently fine to be sprayed evenly and thoroughly on the. cotton in tlremachine.

It will be obvious to those skilled in the art that various changes may be'madein my invention without departing from the spirit thereof and therefore I do not limit myself to what is shown in the drawings and described in the specification, but only 'as indicated by the appended claims.
