This invention relates to improved apparatus fer the winding of thread, and more particularly it relates to apparatus for removably mounting a bobbin or spool on a rotatable spindle. The pres- ``5 ent invention has particular utility in the 'spinning of articial silk.
In the spinning of artificial silk, for example, from a viscose solution; vthe freshlycoagulated thread is wound on to a foraminous or perforated f' bobbin on which it may subsequently 1be subjected to a purifying operation. The bobbin is customarily removably mounted on a rotating spindle. In order to maintain a uniform tensionon the freshly formed thread as it is being drawn from the spinneret, it is necessary toposition the bobbin concentrically of the axis of the rotating spindle and prevent slipping of the ybobbin. relative to the spindle. vThe bobbin must furthermore be removably positioned on the spindle invsuch a manner that a full bobbin can be quickly removed and an empty bobbin substituted therefor.
It is therefore an object of the present invention `to provide an improved bobbin-holding mechanism which will permit ready exchange of bobbins on a. spindle.
It is a further object of the present invention Q concentric to the' axis of the spindle without sub- Y stantial slippage relative thereto.
Other objects of the invention will appear hereinafter. l 7
The various advantageous features of the pres- 315 ent invention will be more clearly apparent by reference to `the following detailed description taken in connection with the accompanying@ illustratins, in which: t l
Figure 1 i's a side elevational view showing a 40 bobbin in position on a bobbin-holding device con-l structed in accordance with the invention.
' Figure 2 is a-vertical cross-sectional view of'the .bobbin-holding device shown in Figure 1. Figure 3 is .an` endview'of the bobbin-holding device shown in Figure 2. A
. Figure 4 isa cross-sectionalview taken along" line l'i-Iof Figure 2.
Figure 5 is an end view of the bobbin-holding deviceof Figure 2 with the cap removed. A
.Referring to the drawings, reference numeral Il designates a rigid base support which is provided with a centrally positioned opening for rev ception of the rotatable 4spindle I3. The spindle lisI provided with a anged shoulder portion I5 55 against which the base support II may rest. The
base support I has a ange I1 and a plurality of longitudinal grooves I9. The gro'oifes I9 extend into the flange I1 thus providing shoulder 2| for holding one end of the bobbin contacting member 23. The base support I is preferably provided 5 with a number of depressions or counter sunk portions 25 which are adapted to cooperate with projection ..21 of the bobbin contacting members. The bobbin contacting members are provided with a number of counter sunk portions 29 `in which 10 may be positioned resilient elements 3| or 33, which elements'may be composed of rubber or any other resilient material or may be springs of any desired configuration so as to resiliently support the bobbin contacting members 23. In the device 15 illustrated, the resilientmembers are constructed of rubber. Two of the fourbobbin contacting members illustrated are lprovided with solid rubber elements 3| which have a relatively small amount of resiliency, and two of the members 23 20 are provided with rubber elements 33 having perforations therein so as to cause them to yield much more readily than the rubber elements 3|. It will thus be obvious that two of the bobbin contacting members'23 will be considerably more 25 yieldable than theother two contacting members. The advantage of having two of the bobbin contacting members moreyieldable than the other two similar members is to prevent an eccentric positioning of the bobbin on the bobbin holding 30 device as will appear hereinafter.
base'thereoi? as is illustrated by the oset portion 39; These oii'set grooves are adapted to t about the bobbin contacting members 23 and particularly the lugs 4| of the said contacting members so as to prevent the contacting members from being removed from the grooves I9. The cap 351s provldedwith a projecting lip which ,covers the 45 ends of members 23'and thereby holds the latter in the base support -The base support. is provided with a plurality'of projecting members y 43 (see Figure 2) which projecting members have circular notches 4'5 inlwhich maybe positioned an v50 annular rubber ring of circular cross section. The cap 35 is also 4provided with circular notches which may be'v aligned withv the circular notchesv 45 so that the annular rubber ring ,.,of circular cross section will tlt within the-'notches off-extensionv 55 hold the cap and base Support together.
It is preferred that the notches cutinto flange I1, whereby to provide the shoulders 2l for retaining the bobbincontacting members, be cut with a greater radius for the bobbin contacting members provided with the more yieldable rubber retaining means 33 than for the contacting members provided with the less-yieldable solid rubber supporting meansv 3l. shown in Figure 2 of the drawings in which the shoulderZl, adapted to hold the bobbin contacting member which is provided with the perforated yieldable supporting means 33, is thinner thanthe shoulder 2| adapted to hold theother bobbin contacting member. The latter shoulder 2l is positioned to hold its contacting member at a distance from the longitudinal axisv of the spindle substantially equal to the inside radius of the bobbin. Thiswill obviously permit the bobbin contacting members supported by the perforated yieldable element 33 to be thrust outwardly from the axis of the spindle a greater distance than the other contacting members. Therefore, in placing the bobbin 41 on the bobbin holding means, the contacting members which are positioned on the more resilient means 33 are pushed inwardly whereas the other bobbin contacting members remain substantially stationary, thus holding the bobbin concentric to the longitudinal axis of spindle I3..v This permissible movement of two of the bobbin contacting members is clearly illustrated in Figure 4 of the drawings by dotted lines. Itis preferred to have the members 3| slightly yieldable so that a bobbin which is bentslightly out of shape may be forced onto the bobbin holding means.
The base support II, the bobbin contactingV members 23, and the'cap 35 may be made of any desirable material which will be inert to treating liquids used in the treatment of artificial silk bers. 'Ihey may, forV example, be constructed of hard rubber, resin condensation products, aluminum or other metal or metalalloys.
of any yieldable material, it being preferred that the members in some of the contacting members be more yieldable than the others. Instead of perforating the relatively dense, non-yieldable, rubber block in order to make it yieldable, a
more yieldable rubber such as, for example;
sponge rubber, may be used in which case it need not be perforated or may be perforated with a smaller number of perforations.
Bobbin-holding devices constructed in accordance with the present invention are adapted to maintain a uniform tension on a bobbin and This is clearlyY The. yieldable members 3l and 33 may-be constructed to maintain the bobbin concentrically of the axis of the rotating spindle. The bobbin contacting means has suilicient surface to prevent slipping of the bobbin relative to the spindle, and at the same time has suillcient yieldability to easily remove the bobbin from the bobbin-holding device when desired. I This yieldability can easily be .varied by substitution of blocks of different dencontacting members, whereby to aid in holdinga bobbin concentrically of said spindle.
2. In a bobbin holder, a basesupport, means for mounting said support on-a spindle, a plurality of radially movable bobbin contacting members positioned in said base support, yieldable members of varying yieldability so constructed and arranged between said support and said contacting members as to permit the various contacting members to move radially inwardly different distances by the positioning of aibobbin on said holder.
3.,In a bobbin holder, a' rigid base support, means for mounting said support on a spindle,
xa plurality of radially movable bobbin contacting members positioned in said base support, a plurality of yieldable members positioned between and in contact with the base support and each of said contacting members, the yieldable members positioned in contact with some of said contacting members having a greater resiliency than the yieldable members positioned in contact with the other contacting members.
4. In a bobbin holder, a base support, means for mounting said support on a spindle, a plurality of bobbin-contacting members mounted in said support, said contacting members radially movable relative to said support; a plurality of yieldable members positioned between said support and each of said contacting members, at least one of said contacting members b eing mounted with greaterv permissible radial movement and being provided with yieldable members of greater yieldability than the remaining contacting members.
