31 Claims.

This invention relates to spinning and twister frames of the ring type.

In twister frames, and in somespinning frames also, but more especially those twister frames in which a vertical ring is used, it is a common practice to apply grease to the ring by hand in order to reduce the friction of the traveller on the ring. This is necessary more particularly in high speed twisters where the friction of the traveller becomes an important operating factor.- Usually it is the practice to grease the ring at every doff. In some cases, however, it is also customary for the machine attendant to apply grease to the rings individually while the frame is running. This is done by stopping the spindles one at a time by means of the knee brake and wiping a small quantity of grease on to the inner surface of the ring by hand. a

The lubrication of the rings in this manner is unsatisfactory for many reasons, among which may be mentioned particularly the fact that it is extremely variable, some rings necessarily receiving much more lubricant than others, it requires considerable labor, and the condition of 5 the rings as to lubrication varies from an over supply immediately after the application of the lubricant to an inadequate supply frequently before the next application. This method often results in throwing an excessive amount of lubricant around over adjacent parts of the machinery and the work, which in some cases is extremely objectionable.

The present invention deals especially with these problems. It aims todevise an apparatus for supplying lubricant to the rings of spinning and twister frames more uniformly and in controlled quantities- It is also an object of the invention to reduce the labor required in lubri- 4O eating rings and to perform this operation automatically.

In view of the fact that the invention is applicable both to spinning and twister frames but is used more generally in the latter type of machine, it will be herein disclosed as applied to a twister frame and both types of machines will be hereinafter included in the term twister frame.

The nature of the invention will be readily understood from the following description when read-in connection with the accompanying drawings, andv the novel features will be particularly pointed out in the appended claims.

' The arrangement shown in the drawings includes a ring rail carrying a series of rings with means for feeding oil from a common source of supply to all of said rings. Referring first to Figs.

2 to 6, inclusive, the ring rail is shown at 2, the rings at 3, and the holders for the rings at 4. Spindles located in operative relationship to cer- 40 tain of the rings are shown in Fig. 2 at 5. All of these parts may be constructed, arranged and operated in the usual manner except for certain details which will be hereinafter described. Usually each ring is pressed into its respective ring holder and each ring holder is secured to the ring rail by screws 6, l and 8, as best shown in Fig. 5, the holder being slotted to receive the three screws.

For the purpose of lubricating the rings, oil or other lubricating material is delivered from a common source of supply, as will later be described, to an oil supply line II! which extends along the rail 2 and preferably is located below the rail in the channel section thereof. This of the supply line conducts oil te a series of lubricating fixtures J2 which are associated with the respective rings and ring holders, each fixture preferably being located betweentwo adjacent ring holders and arranged to conduct oil from the supply'line to both ring holders with which it is associated. The supply line l8 may conveniently consist of copper tubing and may be connected to the fixtures|2 by fittings of well known forms. Each fixture includes an oil chamber l3, Figs. 4 to 6, through which the oil flows from one section of the supply line to another.

The fixtures l2 are each secured to the lower side of the ring rail by a screw l4, and they are each provided with two short hollow nipples |5-|5 which fit somewhat loosely into holes l6 formed in the lower surfaces of the ring holders. .Oil is delivered to the fixtures under pressure and flows upwardly through lubricators l1 and through the nipples |5 into the chamber I6, thence through oil ducts |8 in the ring holder and through additional ducts 26 in the rings themselves into grooves 2 I, one such groove being formed in the upper part of the inner circumferential surface of each ring. A gasket 22, Fig. 4, surrounding each nipple |5 prevents leakage of the oil around the nipple.

While the lubricator used may take any one of several forms, the type shown in Fig. 4 has proved very satisfactory. It is of a form readily obtainable on the market and consists of a body which is threaded into an internally threaded bore 23 in the fixture 2, the bottom of this bore being normally closed by a screw threaded plug 24. The lubricator includes a screen 25 holding a body of fibrous material 26 which acts as a filter, the screen being held in place by a ring 21 which is pressed into the body H. A hole 28 of accurate dimensions isdrilled axially in the body l1 and is partly filled by a pin 29. At the upper end of this pin is a valve 38 which normally is held seated by a coiled spring 3| backed up by a cap 32. Each pin 29 is made accurately so that the dimensions through which the oil must escape are practically the same at each lubricator. The

' springs 3| also are substantially uniform and they hold the heads of the valves seated with a substantial degree of pressure.

It will be clear, therefore, that if a predetermined quantity of oil under suflicient pressure is delivered to the supply line l6, all of the valves 30 in the lubrlcators will be lifted substantially simultaneously, and approximately uniform quantities of oil will be delivered to all of the grooves 2| in the rings. This oil tends to overflow the groove in each ring and to run down the inner surface of the ring and it is distributed around the entire surface of the ring by the traveller. The oil supply may be such that the traveller will act on it to form a meniscus which will persist as the traveller rotates around the ring.

By delivering the oil to the supply line I8 at predetermined intervals and in predetermined quantities, a substantially uniform lubricating condition can be maintained at each ring.

For the purpose of delivering oil to the supply line in this manner, we have provided a pump with mechanism for operating the pump intermittently from the driving mechanism of the twister frame. Referring to Fig. 1 it will be seen that the supply lines |8|6 for the'ring rails at the opposite sides of the frame are both connected to a main supply line 35 which leads from a pump cylinder 36, a checkvalve being located at the outlet of the cylinder to prevent a back flow of lubricant into the cylinder. This cylinder, as better shown in Fig. 10, is connected to the bottom of a supply tank 31. A piston 38 is mounted to reciprocate in the cylinder 36, the piston including a ball check valve 39. When the piston is lifted the oil fiowsfreely past the ball 39 into the lower part of the cylinder 36, but when the piston later is forced downwardly by the action of the spring 40, the ball check valve closes and the piston forces the oil trapped in the cylinder below it out through the supply lines 35 and III to the rings.

The mechanism for lifting the piston 38' comprises a cam 4|, Figs. 9 to 12, arranged to engage a roll 42 mounted in the end of a forked lever 43 which is fulcrumed on the tank 31 at 44. The piston rod 45 is located between the arms of, the lever 43 and is encircled by a cross head 46 which is pivoted to the lever 43 and is backed up by a nut 41 threaded on the piston rod 45. A check nut 48 locks the nut 41 in adjusted position. This arrangement provides a convenient means for adjusting the length of stroke of the piston 38.

The operating mechanism for the pump is conveniently driven from the cam shaft 50, Fig. 1, of the builder motion of the twister frame, this cam shaft, in turn, being driven in the usual manner by a worm gear connection with the driving mechanism for the other parts of the machine including the spindle driving drum and the feed rolls. All of these units are geared together so that the shaft 50 rotates in a definite time relationship to the other driven members of the machine. A sprocket wheel 5| on the cam shaft 56 is connected by a chain 52 with another sprocket wheel 53 on the driving shaft 54 of the vpump operating mechanism. This shaft therefore is driven continuously. The mechanism is arranged, however, to rotate the cam 4| once at the end of a predetermined and adjustable interval of time, such rotation serving to raise the piston rod 45 and then release it, thus allowing the spring 48 to depress the piston 38.

This mechanism includes a pinion 55 keyed to the driving shaft 54 and adapted to mesh with and drive a gear 56 on the shaft 51 on which the cam 4| is mounted. The teeth of the gear 56, however, have been removed from a certain section so that when this smooth section or gap arrives opposite the pinion 55 thegear 56 and the cam shaft 51 will stop. Movement of these parts is definitely arrested at this time by the engagement of a pin 58, Figs. 11 and 12, with the thickened portion 60 of a catch plate or stop plate 6|, the pin 58 being secured rigidly in the gear 56. In order to start these parts into rotation again a pick wheel or ratchet wheel 62 is located loosely on the shaft 57 and is arranged to be rotated step by step by a pawl 63 which is pivoted on an arm 64 mounted to rock on the shaft 51, this arm being pivoted to an eccentric 'strap 65 which is oscillated continuously by an ec-- centric 66 fast on the driving shaft 54. This shaft turns slowly so'that the movement of the pawl 63 is relatively slow. The point in its swing at which it engages the teeth of the pick 'wheel 62 is controlled by a guard 61 lying closely adjacent to the pick wheel, the pawl 63 running on the surface of this guard. The guard is supported on a stationary plate 68 and is adjustable thereon by means of a bolt and slot connection III with said plate 68. The arrangement is such that the pawl 63 may be allowed to move the pick wheel forward from one to a dozen or more teeth, as desired. Consequently, at a time determined by the setting of this guard, a pin II which projects rigidly from the pick wheel will strike the lug 12, Fig. 11, projecting from' the catch plate and rock this catch plate backwardly about its pivot 13, thus moving the stop lug ill out of engagement with the pin Bl. At this time the pin I4 which projects from the pick wheel 62 will engage another pin 15 projecting from the cam shaft 51 and will move the'whole cam shaft forward by an angular distance depending upon the movement imparted to the pickwheel by the pawl 63. This action is also aided by a spring 18, Fig. 12, one end of which is secured to a stationary pin, while its opposite end is' secured to a plate 11 that is pivoted to an eccentric stud IB projecting from the end of the cam shaft, the arrangement being such that this spring tends to rotate the cam shaft in the same direction in which it is rotated by the action of the pin 14 on the pin 15.. These parts give the gap gear 56 a suflicient rotative movement to bring its teeth into mesh with those of the driving pinion 55, whereupon the cam shaft 51 is given one complete revolution and is then stopped again, .the operations above described being repeated so long as the machine continues to run.

In order to avoid any possibility of breaking the parts in the event that the gears are not brought into proper mesh at the end of the pick-- ing operation, the gear .56 is mounted; on a squared portion 80, Fig. 11, of the cam shaft El, and is provided with a rectangular hole into which the squared part 80 fits. A spring 8! acts between the gear and the part 80 to hold the gear normally centered on the shaft, but permits the movement of the gap gear 58 away from the driving pinion in the event that the teeth do not mesh properly; This permits some slip to occur between the gears when the gap gear starts up which will result in bringing them into proper mesh. A dog 19 pivoted on the sta tionary plate 68 engages the pick wheel $2 and prevents reverse rotation of this wheel. While the cam shaft 51 is making its revolution, the pin 15 catches up with the pin 14 and moves the pick wheel 62 far enough to carry the pin H past the lug 12 on the catch plate 6! before the rotation of the cam shaft is stopped. the parts in approximately the position shown in Fig. 11 in readiness for the picking operation to begin again.

The oil tank 81 is equipped with a filling spent @3, the end of which normally is closed by a pivoted cover 8 When the twister frame is in operation the apparatus above described operates automatically to deliver 011 in approximately predetermined quantities and at predetermined intervals to all of the rings in the ring rail of the machine. The length of these intervals can be adjusted by adjusting the guard 61, as above described, to predetermine the amount which the pick wheel will be advanced by each stroke of the pawl. The quantity of olldelivered at each interval can be predetermined by adjusting the nuts t! and 48 on the pump piston rod 45, so as to adjust the operating stroke of the pump. The arrangement is such that the pressure of the oil at all of .the lubricators is substantially the same. The

lubricators control the flow of the oil from the oil supply line to the respective rings with which they are associated so that approximately the same quantity of oil is delivered to each ring. This arrangement, therefore, relieves the oper- .of the rings.

This leaves ator from any duty connected with the lubrication At the same time it provides a far more constant and uniform supply of lubricant to the rings than has been obtainable heretofore, avoiding both the excessive over supply at times and the inadequate supply at other times which has been an important objection to prior methods.

In some machines it is desirable to provide for the manual control of the pump operating mechanism so that the pump can be brought into operation by hand at any desired time, as for example, when the machine'attendant is starting up the twister after the, dofling operation has been completed. For this purpose a. rod 86, Fig. l, is pivoted to the catch'plate SI and runs to an arm 8'! secured on a rock shaft 88 which is' mounted in the end frame 90 of the machine. At the opposite side of the frame plate a handle 9| is secured tov the rock shaft 88 so that by depressing this handle the catch plate 6| can be rocked far enough .to release the pin 58, Fig. 11, in the same way that it is released automatically by the mechanism above described.

A somewhat different arrangement is shown in Figs. 7 and 8 adapted for use with large rings. Each of these rings 3f is providedwith a groove 92, Fig.8, extending around the entire circumference of the ring and which communicates through ducts 93 with a groove 2| like that formed in the rings 3. This ring has an intermediate bearing portion 94 which is engaged by the knee of the traveller T. Oil flows down over this surface and part of the oil flows through holes 95 to the outside of the ring where it serves to lubricate the surface on'which the heel of the In this construction some clearance is allowed between each nipple i5 and the hole therefor in the. ring holder so that the holder can be adjusted independently of the fixture and without disturbing the operative relationship of the fixture to the holder. A similar clearance is provided for this purpose in the construction shown in Fig. 4.

While we have herein shown and described a preferred embodiment of our invention, it will be understood that the invention may be embodied in other forms without'departing from the spirit or scope thereof. It should also be understood that while we have referred particularly to the lubricating material as oil, since this is the material which we prefer to use, other lubricants could be used with minor modificationsof the system shown.
