C., assignor to Burlington Mills Corporation, Greensboro, N. C. Application April 7, 1945, Serial No. 587,149 3 Claims. (Cl. 57-1l6) 1 My invention relates to a system of lubricating ñier blocks located on the delivery bobbing of an 2 to high tension when the machine is in motion. The invention will be more readily understood up-twist spinning frame. by reference to the accompanying drawing and A conventional flier consists essentially of a body portion, a foot member adapted to lit into an aperture formed on the end of the bobbin and hier Wires supported by the body of the block. The ñier is associated with the bobbin from which the following detailed description in which a spe ciñc embodiment of the inventive thought is set forth by way of illustration rather than by way of limitation. In the drawing: Fig. 1 is an elevation partly in section showing and is free to rotate on the bobbin spindle; the 10 the cooperating parts of the spinning machine to which the oiling device is to be applied; rayon withdrawn from the bobbin is tensioned Fig. 2 is a vertical sectional View on a larger and provided with a twist before it is wound on a scale of the upper part of Fig. 1 showing the lubri second or storage bobbin; preparatory to use on rayon or other material is to be unwound or spun fabricating machines. The spinning machine comprises a plurality of spindles having bobbing mounted thereon, the bobbins upon which the rayon is wound before it is twisted being below the line of bobbins which receive the rayon after it has been properly ten sioned and twisted. When the spinning machine is in motion, the yarn running from the delivery bobbin to the take-up bobbin is tensioned resulting in stretched yarn and broken ends due to the high tension. If the stretched yarn and broken lilament yarn are cating features in detail; Fig. 3 is a horizontal section on the line 3--3 of Fig. 2; Fig. 4 is a detail Vertical section showing the oil supply compartment at the top of the spindle; and Fig. 5 is a plan view of the machine on a smaller scale than Fig. l. Referring in detail to the drawing, reference numeral It denotes a conventional spindle hav ing a bobbin II mounted thereon. The numeral i2 denotes the flier block which carries flier arms I3, I3. These elements may be of conventional allowed to go through a defect will appear in the design. For the purpose of lubricating the flier goods made from this particular run of rayon or block the upper portion I4 of the spindle is made yarn. ~ hollow to provide a compartment E5 therein In order to eliminate the excessive tension, bro ken filaments and stretched yarn, according to 30 which serves as a reservoir for the oil supply. A cylindrical Wick It is inserted in the oil supply present practice, it is necessary to oil the hole in compartment, the wick being slightly shorter the flier block Which fits around the spindle, It than the compartment so that when the wick is will be appreciated that in the average rayon forced to the bottom of the compartment there throwing plant, comprising iifteen thousand to twenty-uve thousand spindles, considerable time 35 is left a space between the wick and the top of is required by the operatorsl in oiling the flier the spindle. This space is provided to facilitate the introduction of oil to the wick and compart blocks when full bobbins are put on the spindle ment when the spinning machine is in motion. as well as removing bobbins from the spindles In the hollow upper portion I4 of the spindle which have broken ends in order that the hole in 40 two oil supply holes or lines il and I8 are pro the flier block may be oiled. vided extending from the outside of the spindle It is the purpose of the present invention to Wall to the oil supply compartment, these open prevent stretched yarn and broken ends in the ings being at a position where the flier block rayon as it is taken off the lowei` bobbin `and revolves. It will be noted that the oil lines I1 wound on the upper one, thus eliminating the necessity of operators oiling the flier block hole d and i8 are at different levels, the distance apart varying with the size of the flier block. By so when full bobbins are put on or when removing spacing the oil openings a more efficient lubrica bobbins having broken ends in order that the flier tion of the íiier block is obtained. While two block hole may be oiled. This is accomplished by openings are shown it will be obvious that the providing the spindle holding the delivery bobbin and flier block with an oil supply compartment 50 invention in its broadest aspects is not limited to this number, as one or more openings may which by means of a wick and oil lines keeps the be provided depending on the extent of lubrica flier block oiled. tion desired. Similarly the size of the openings 'I'he object of my invention is to provide an im proved method of oiling the flier block, adapted to prevent stretched yarn and broken iilaments due may be varied as desired. The Wick I5 may be supplied with oil when the 2,409,523 3 spindles are not in motion, a light grade of oil being preferably employed. The space 20 be tween the top of the wick I6 and the top of the oil supply compartment I5 makes it possible to supply sufficient light grade oil to last for sev The invention has been described in detail for the purpose of illustration, but it will be obvious eral weeks, depending on the speed of the spin ning machine. The wick I6 soon absorbs the oil, I claim: 1. In a spinning machine, comprising a spindle having a delivery bobbin mounted thereon, and a flier block ñtting over the upper portion of leaving the oil space 20 .above the wick empty. The oil which has been absorbed by the wick travels along the wick by capillary action, and when the machine is in motion centrifugal force throws the oil out through the oil lines I'I and I3 against the inside of the flier block I2. This block revolves slightly faster than the spindle I0 or delivery bobbin I I, causing friction between the inside of the flier block and the outside of the spindle rand producing a high tension on the end running from the delivery bobbin to the take-up bobbin (not shown).
