BOBBIN SKEWER.
Original application filed J'anuary 4, 1917, Serial No. 140,561. Divided and this application filed November 19, 1926.
In Patent No. 1,267,977, granted to me May 28, 1918, there is disclosed a machine for rewinding yarn from bobblns to form cheeses. The bobbin being unwound lies upon its side in a bobbin pocket or holder, and revolves as theyarn is drawn off from the side of the bobbin.
There are advantages in drawing yarn off the end of the bobbin. This, however, requires that the bobbin be firmly held by its butt end so that it cannot turn or rise.
The object of the present invention, generally stated, is to provide means in the nature of a skewer upon which the bobbin may be supported and firmly held against turning or rising as theyarn is drawn off the end of the bobbin at high speed.
A particular object of the invention is to provide means of the character stated which shall require a minimum of effort or attention on the part of the operator.
This application is a division of my application Serial No. 140,561, filed January 4, 1917 (now Patent No. 1,611,890, dated December 28, 1926).
In the accompanying drawings,
Figure 1 is a vertical sectional view illustrating one embodiment of my invention.
Fig. 2 is a transverse section of the skewer taken in the plane of line 2-2 of Fig. 1.
While the invention may be employed in connection with bobbins of various types, I have herein shown. ordinary warp bobbins with yarn wound thereon with the so-called warp wind, wherein the yarn is wound upon the bobbin in concentric cylindrical layers, as distinguished from the filling wind, wherein the yarn is wound upon the bobbin in successive conical layers. wound yarn may be successfully drawn off the end of a bobbin at greater speed than filling-wound yarn.
The bobbins a are supported in a magazine which may be of any suitable construction, that herein shown comprising a disk 2 having a hub 3 which is fixed upon a vertical spindle 4. Said spindle is rotatably mounted in bearings 6 and 7 in the supporting framework. Means of any desired character may be provided for rotating the magazine step by step as required to move a spent bobbin out of running position and place a reserve bobbin in running position. The magazine comprises skewers 8 on which the Warp Serial No. 149,346.
annular shoulder 11 upon which the butt of the bobbin may stand. Above the shoulder 11 the skewer is provided with two annular surfaces 12 and 13 adapted to engage the walls of the bore of" the bobbin when the skewer is expanded, the surfaces 12 and 13 being spaced apart in order that the bobbin shall be gripped at two separated places and thus be firmly and concentrically. held at each of those places. I
The means for expanding the skewer comprises a pin 14 mounted in a tubular guide 15 carried by the plate 2.. The upper end of the guide 15 is. upwardly tapered as at 16, and fits within the correspondingly tapered lower end ofwthe' skewer. I The upper end of the pin 14 has a downwardly tapering surface 17 adapted, when the pin 1% is moved downwardly, to force the upper ends of the segments 9 apart and thus cause the skewer to engage the bobbin. A coiled expansive spring 18 surrounds the pin 14 within the guide 15 and bears against an annular shoulder 19 on the pin. It will be seen that the sprin 18 tends to cause the tapered surface 1 to enter between the upper ends of the segments 9 and also tends to move the skewer bodily downward over the tapered surface 16, the result being toexpand' the skewer into clamping engagement with the interior walls of the bobbin. skewer comprises the clamping portions 12 and 13 which are movable by the conical surfaces 16 and 17 until they come into contact with the interior walls of the bobbin, the skewer is capable of firmly clamping bobbins having bores of various sizes and tapers.
The skewers are caused to clamp and release the bobbins in the rotation of the magazine by means of a cam flange 20 on the bracket that supports the bearings 6 and 7. The low portion of the flange 20 is indicated at 21 in said figures, the portion 21 being joined to the elevated portion of the flange by the inclines 22, only one of which inclines Inasmuch as the is shown in the drawing. In the rotation of the magazine the pins 14 are moved around on the flange 20. When the pins are on the elevated portion of the flange, the skewer is in the contracted condition shown at the right-hand side of Fig. 1. When the pins l l are above the low portion 21, the skewers,
are in the expanded or clamping condition shown at the left-hand side of Fig. 1.
In use, the operator places a bobbin on a skewer 8 while the latter is above the high portion of the cam flange 20. When the skewer reachesa position above the low portion of the cam flange, the skewer is automatically actuated to clamp or look the bobbin against rotation or upward movement as the yarn is being drawn off the upper end of the bobbin. When the yarn is drawn off at high speed, the yarn balloons and thus swings clear of the yarn mass, and the tip of the bobbin, even when the yarn extends from the lower portion of the yarn mass. By usingwarp-wound bobbins and supporting them by means firmly engaging the butt, it
is possible to rewind very high speed and under low tension.
It will be apparent that the bobbin-supporting and locking means herein disclosed requires a minimum of attention and eiiort on the part of the operator. The skewer enters only the lower portion of the bobbin bore, hence the bobbin and the skewer can be engaged and disengaged by means of a relatively short movement. Notwithstandingtheshort hold which the skewer has on with the carrier at two longitudinally separated points.
2. A skewer for supporting ayarn carrier and adapted to enter only the lower end of the carrier, said skewer having, in combination, a plurality of longitudinal segments, and member movable into place between said segments to force the latter outwardly into clamping engagement with the carrier at two longitudinally separated points.
3. A yarn-carrier support consisting of a relatively short skewer adapted toenter only the-lower end of the yarn carrier internal means for expanding the lower end of the skewer into engagement with the carrier, and internal means for expanding the upper end of the skewer into engagement with the carrier.
In testimony whereof, I have hereuntoat fixed my signature. v
